Title: Information management method, information management device, information management program, and call receiving device

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application is a continuation application of International Application No. PCT/JP2007/064999, filed Jul. 31, 2007. The contents of this application are incorporated herein by reference in their entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an information management method, an information management device, an information management program, and a call receiving device. 
     2. Discussion of the Background 
     Pay-per-click systems have been used as one method of advertising using web pages on the Internet. A pay-per-click system is a system in which an advertising agency charges an advertisement fee to an advertiser according to the number of times an item of advertisement information displayed on a web page is clicked. 
     For example, when advertisement information of the advertiser is posted on a web page of an advertisement providing site and a user who has viewed the page selects (clicks) the advertisement information, a website managed by the advertiser is linked to and the user can view detailed information regarding the advertisement information. In addition, according to the number of clicks made on the advertisement information, the advertiser pays an advertisement fee to the administrator of the portal site. 
     This method is frequently used in portal (entrance) sites that have many users (viewers) and are capable of providing high advertising effectiveness. The administrator of the portal site establishes frames for advertisements as part of the site page, runs advertisements by lending the frames for advertisements to advertisers, and collects advertisement fees according to the number of clicks made on each item of advertisement information. 
     However, this pay-per-click system has a problem in that, when an advertiser does not have their own site, no site can be set to be linked to and no detailed information regarding the advertisement information can be provided. Moreover, because payment of an advertisement fee is generated simply through clicks made on advertisement information, the effect of “direct contact with users (clients)” cannot be obtained for the cost of advertising. 
     Moreover, because the advertisement fee is generated according to the number of clicks made even when a user unintentionally clicks the advertisement information or intentionally repeats clicking, the association between the advertising effectiveness and the advertisement fee may be decreased. 
     Therefore, another system has been suggested in which a phone number corresponding to each advertiser is posted on a web page of an advertisement providing site along with the advertisement information, and when a user who has seen the information calls the advertiser, an advertisement fee is charged based on the establishment of the phone call. One of the systems using this advertising method is referred to as a Pay-Per-Call system, such as the one described in Japanese Patent Application Publication No. 2005-115945, for example. 
     However, when posting advertisement information on a plurality of advertisement providing sites, if all of the posted phone numbers are uniformly the same phone numbers, it is impossible to distinguish which advertisement providing site the user has seen to make the phone call. Therefore, there is a problem in that it is impossible to ascertain which advertisement providing sites have a high advertising effectiveness and which advertisement providing sites have a low advertising effectiveness. 
     Therefore, another method has been suggested in which different phone numbers are allocated for each item of advertisement information and posted on different advertisement providing sites in order to ascertain, based on the phone number the user calls, which advertisement providing site the user has seen to make the phone call (e.g., see WO/2007/015531). According to this method, the advertising effectiveness of each advertisement providing site can be ascertained 
     Today, there are many advertisement providing sites. For example, when an advertiser posts advertisement information of their company on 10,000 advertisement providing sites, if different phone numbers are allocated to each of these sites and posted, it is necessary to prepare 10,000 numbers, which is a large number of phone numbers. 
     Moreover, advertisement information of a plurality of items of merchandise (subjects of advertisements, such as products and services) may be posted in one advertisement providing site. Supposing that the advertiser posts advertisement information for 10,000 types of merchandise in one advertisement providing site and allocates different phone numbers to each item of merchandise, it is necessary to prepare 100,000,000 phone numbers for 10,000 sites×10,000 items of merchandise. 
     In this way, to allocate different phone numbers to each of many advertisement providing sites and items of merchandise, it is necessary to have phone numbers with a large number of digits. However, if the number of digits of the phone number is increased, the frequency of misdialing by users making a phone call will increase and the number of users who give up making the call due to the complexity of the process will increase, leading to declined advertising effectiveness. Depending on the specifications on the side of the call receiving system, there are restrictions on the number of phone number digits that may be allocated to advertisement information, and it may not be possible to readily increase the number of digits. 
     Moreover, the number of advertisement providing sites on which the advertiser posts the advertisement information and the number of items of merchandise handled may vary, and it is therefore necessary to ensure a generous number of phone numbers for each of the advertisers (or each of the advertisement providing sites). In this way, even if the number of digits of the phone numbers is increased, the phone number resources are soon depleted and it is necessary to further increase the number of digits of the phone numbers to secure the necessary number of phone numbers for each of the advertisers. 
     SUMMARY OF THE INVENTION 
     According to one aspect of the present invention, an information management method is for managing identification information that is explicitly or implicitly provided in a web page and that is for identifying a call receiver. The information management method includes changing the status of the identification information rendered available for a call connection to a first call receiver from being available for sending to the web server hosting the web page into being unavailable for sending. The status of the identification information rendered unavailable for the sending is changed into being available for a call connection to a second call receiver. The status of the identification information rendered available for a call connection to the second call receiver is changed into being available for sending to the web server or other web servers. 
     According to another aspect of the present invention, an information management device is for managing identification information that is explicitly or implicitly provided in a web page and identifies a call receiver. The information management device includes a first controller, a second controller, and a third controller. The first controller is configured to change the status of the identification information rendered available for a call connection to a first call receiver from being available for sending to the web server hosting the web page into being unavailable for sending. The second controller is configured to change the status of the identification information rendered unavailable for the sending into being available for a call connection to a second call receiver. The third controller is configured to change the status of the identification information rendered available for a call connection to the second call receiver into being available for sending to the web server or other web servers. 
     According to still another aspect of the present invention, an information management device includes a management-information acquisition part, a first determination part, a second determination part, and an identification-information sending part. The management-information acquisition part is configured to acquire management information for identifying advertisement information provided in a web page from a web server hosting the web page. The first determination part is configured to determine whether identification information for identifying a call receiver and the acquired management information are mutually associated. The second determination part is configured to determine whether the identification information is available for provision to the web server. The identification-information sending part is configured to send the identification information to the web server if the identification information is mutually associated with the management information and available for the provision. 
     According to yet still another aspect of the present invention, an information management program is for managing identification information that is explicitly or implicitly provided in a web page and that is for identifying a call receiver. The information management program causes a computer to perform changing the status of the identification information rendered available for a call connection to a first call receiver from being available for sending to the web server hosting the web page into being unavailable for sending. The status of the identification information rendered unavailable for the sending is changed into being available for a call connection to a second call receiver. The status of the identification information rendered available for a call connection to the second call receiver is changed into being available for sending to the web server or other web servers. 
     According to yet still another aspect of the present invention, an information management program causes a computer to perform acquiring management information for identifying advertisement information provided in a web page from a web server hosting the web page. Whether identification information for identifying a call receiver and the acquired management information are mutually associated is determined. Whether the identification information is available for provision to the web server is determined. The identification information is sent to the web server if the identification information is mutually associated with the management information and available for the provision. 
     According to the other aspect of the present invention, a call receiving device includes a call receiving part, a call-receiver-information receiving part, and a call connection part. The call receiving part receives a call based on identification information that is explicitly or implicitly provided in a web page and is for identifying a call receiver. If any call receiver is associated with the identification information, the call-receiver-information receiving part receives information of the call receiver, and if no call receiver is associated with the identification information, the call-receiver-information receiving part receives information indicating the absence of call receivers. If the information of the call receiver is received, the call connection part connects the call to the call receiver, and if the information indicating absence of call receivers is received, the call connection part renders the call unconnected.

     DESCRIPTION OF THE EMBODIMENTS 
     The embodiments will now be described with reference to the accompanying drawings, wherein like reference numerals designate corresponding or identical elements throughout the various drawings. 
     An information management method according to an embodiment of the present invention is an information management method for managing identification information that is explicitly or implicitly provided in a web page and identifies a call receiver, the method including: changing the status of identification information rendered available for a call connection to a first call receiver from being available for sending to a web server hosting the web page to being unavailable for sending; changing the status of the identification information rendered unavailable for sending into being available for a call connection to a second call receiver; and changing the status of the identification information rendered available for a call connection to the second call receiver into being available for sending to the web server or other web servers. 
     Because the status of the identification information rendered available for a call connection to the first call receiver is changed from being available for sending to the web server to being unavailable for sending, and then rendered available for a call connection to the second call receiver and rendered available for sending to the web server or other web servers, different call receivers may be dynamically connected to one identification information. Therefore, this method may contribute to the effective use and prevention of depletion of identification information. 
     Herein, “explicitly or implicitly provided in a web page” includes cases in which identification information is explicitly displayed as character information on a web page. It also includes situations in which the information is not explicitly displayed on a web page but is internally associated with data of that web page and may be explicitly provided based on some manipulation of the web page and in which it is possible to make a call to a call receiver associated with the identification information. 
     Identification information is information that identifies a call receiver by being associated with the call receiver and is composed of numbers with multiple numbers of digits, for example. The identification information is also associated with advertisement information, for example, and different identification information may be allocated to each item of advertisement information. 
     The status in which the identification information is available for sending to a web server refers to a status in which, for example, when the user accesses a web page, the identification information associated with the advertisement information may be sent to the web server and displayed on the web page. “The status in which the identification information is available for a call connection to a first call receiver” refers to a status in which a call based on the identification information may be connected to the first call receiver. 
     Changing the status of identification information from being available for sending to the web server to being unavailable for sending may be executed based on the establishment of a first predefined condition. 
     The establishment of the first predefined condition includes fulfillment of a certain period and fulfillment of a certain number of times, for example. For example, in cases in which the identification information is rendered unavailable for sending to the web server based on the fulfillment of a certain period, the identification information may be rendered available for provision at the web server for only a certain period and subsequently rendered unavailable for provision at the web server. 
     Then, the identification information rendered unavailable for provision is rendered available for a call connection to a second call receiver different from the first call receiver and may be provided to the web server, and one item of identification information may thereby be associated with various call receivers at staggered times and the identification information may be effectively reused. 
     On the other hand, if the identification information and the advertisement information are mutually associated, the identification information to be associated with one item of advertisement information may be changed in various ways at staggered times. Therefore, by ascertaining which item of identification information the call from the user was based on, it is possible to ascertain the period of time or time zone in which that advertisement information is exerting a high advertising effectiveness. 
     The method may further include a step of, after a predefined period has elapsed following the execution of changing the status of the identification information from being available for sending to the web server to being unavailable for sending, changing the status of the identification information into being unavailable for a call connection to the first call receiver. Then, that predefined period may be extended or reduced based on the establishment of a second predefined condition. 
     The establishment of the second predefined condition includes, for example, the presence or absence of calls based on the identification information within that predefined period. That is, if there is a call based on the identification information within the predefined period, the predefined period may be extended, and if there is no call, the predefined period may be reduced. In this way, even if the identification information is no longer provided to the web page, the advertising effectiveness of the advertisement information associated with that identification information will still remain, and if a call based on that identification information is sometimes made, a period (predefined period) available for properly connecting that call to the first call receiver may be extended. 
     In addition, herein, “unavailable for a call connection” refers to rendering a call based on that identification information unconnected to the call receiver. That is, it refers to a situation in which, even if there is a call based on the identification information, that call is not caused to be received by the call receiver by processing it to be busy, placing it on hold, or processing a response announcement that the connecting destination does not exist. 
     A period unavailable for connection from the execution of changing the status of the identification information into being unavailable for a call connection to the first call receiver to the execution of changing the status into being available for a call connection to the second call receiver may be extended or reduced based on the establishment of a third predefined condition. 
     The establishment of the third predefined condition includes the presence or absence of calls based on the identification information within that period unavailable for connection, for example. Specifically, if there is a call based on the identification information within the period unavailable for connection, the period unavailable for connection may be extended, and if there is no call, the period unavailable for connection may be reduced. In this way, even if the identification information has not been provided to the web page for a long period, the advertising effectiveness of the advertisement information associated with that identification information will still remain, and if a call based on that identification information is sometimes made, a period in which the call is unconnected without making a connection to a new second call receiver for a while may be extended. 
     An information management device according to an embodiment of the present invention is an information management device for managing identification information that is explicitly or implicitly provided in a web page and identifies a call receiver, wherein the information management device: changes the status of the identification information rendered available for a call connection to a first call receiver from being available for sending to the web server hosting the web page to being unavailable for sending; changes the status of the identification information rendered unavailable for sending into being available for a call connection to a second call receiver; and changes the status of the identification information rendered available for a call connection to the second call receiver into being available for sending to the web server or other web servers. 
     Because the status of the identification information rendered available for a call connection to the first call receiver is changed from being available for sending to the web server to being unavailable for sending and then rendered available for a call connection to the second call receiver and rendered available for sending to the web server or other web servers, different call receivers may be dynamically connected to one identification information. Therefore, this method may contribute to the effective use and the prevention of depletion of identification information. 
     The device may further include: a connection-status changing part that changes the status of the identification information into being unavailable for a call connection to the first call receiver, and changes the status of the identification information into being available for a call connection to the second call receiver; a call-reception-information receiving part that receives call-reception information indicating that there was a call based on the identification information; and a period changing part that, if receiving the call-reception information within a predefined period between changing the status of the identification information into being unavailable for the sending and changing the status into being unavailable for a call connection to the first call receiver, extends the predefined period, and if receiving the call-reception information within a period unavailable for connection between changing the status of the identification information into being unavailable for a call connection to the first call receiver and changing the status into being available for a call connection to the second call receiver, extends the period unavailable for connection. 
     With the operation of the period changing part, even if the identification information is no longer provided to the web page, depending on the degree of remaining advertising effectiveness of the advertisement information associated with that identification information, a period (predefined period) in which a call based on that identification information can be properly connected to the first call receiver may be extended, or a period in which that call is unconnected (period unavailable for connection) may be extended. 
     An information management device according to an embodiment of the present invention includes: a management-information acquisition part for acquiring management information for identifying advertisement information provided in a web page from the web server hosting the web page; a first determination part for determining whether identification information for identifying a call receiver and the acquired management information are mutually associated; a second determination part for determining whether the identification information is available for provision to the web server; and an identification-information sending part that sends the identification information to the web server if the identification information and the management information are mutually associated and available for the provision. 
     Because the identification-information sending part sends the identification information if the management information and the identification information are mutually associated and if that identification information is available for provision to the web server, the identification information will not be sent to the web server if the management information and the identification information are not mutually associated or if the associated identification information is unavailable for provision. Thus, sending/not sending to the web server may be properly managed depending on the status of the identification-information. 
     Herein, management information is information for identifying the advertisement information, including, for example, an advertiser ID allocated to each advertiser (hereinafter referred to as MID), an advertising agent ID allocated to each advertising agent (hereinafter referred to as DID), an ID allocated to each product or service (merchandise) related to an advertisement (hereinafter referred to as PID), and an ID allocated to each site of an advertisement provider (partner) that is associated with the advertising agent and to which a request to post the advertisement information is made (hereinafter referred to as SID). Also, if an individual posts the advertisement information on their web page, blog, etc., based on a contract with the partner, an ID allocated to each personal page or personal blog ID (hereinafter referred to as UID) may be included. 
     The device may further include an identification-information-association executing part that, if the identification information and the management information are not mutually associated, associates the identification information with the management information. 
     Because the identification-information-association executing part associates the identification information with the management information if the identification information and the management information are not mutually associated (i.e., if the association between both is removed), the identification-information sending part may, if receiving the management information from a web server, always send the identification information to that web server. Thus, in the web page, the identification information associated with the advertisement information may be displayed at all times. 
     In addition to extracting that identification information from identification information not associated with any management information, by extracting it from identification information not associated with any call receiver, associating it with a call receiver related to the advertisement information, and also associating it with the management information to send it to the web server, a call based on the identification information provided in the web page may be properly connected to that call receiver. 
     The information management device according to claim  8 , further including an identification-information-association executing part that, if the identification information is unavailable for provision to the web server, associates other identification information different from the identification information with the management information. 
     Because the identification-information-association executing part associates other identification information with the management information if the identification information associated with the management information is unavailable for provision, the identification-information sending part may, even if the identification information is unavailable for provision when acquiring the management information from a web server, send other identification information to the web server. Thus, in the web page, the identification information associated with the advertisement information may be displayed at all times. 
     In addition to extracting other identification information from identification information not associated with any management information, by extracting it from identification information not associated with any call receiver, associating it with a call receiver related to the advertisement information and also associating it with the management information to send it to the web server, a call based on other identification information provided in the web page may be properly connected to that call receiver. 
     An information management program according to an embodiment of the present invention is an information management program for managing identification information that is explicitly or implicitly provided in a web page and identifies a call receiver, wherein the information management program causes a computer to fulfill functions to: change the status of the identification information rendered available for a call connection to a first call receiver from being available for sending to the web server hosting the web page to being unavailable for sending; change the status of the identification information rendered unavailable for sending into being available for a call connection to a second call receiver; and change the status of the identification information rendered available for a call connection to the second call receiver into being available for sending to the web server or other web servers. 
     Because the status of the identification information rendered available for a call connection to the first call receiver is changed from being available for sending to the web server to being unavailable for sending and then rendered available for a call connection to the second call receiver and rendered available for sending to the web server or other web servers, different call receivers may be dynamically connected to one identification information. Therefore, this method may contribute to the effective use and the prevention of depletion of identification information. 
     An information management program according to an embodiment of the present invention causes a computer to function as: a management-information acquisition part for acquiring management information for identifying advertisement information provided in a web page from the web server hosting the web page; a first determination part for determining whether identification information for identifying a call receiver and the acquired management information are mutually associated; a second determination part for determining whether the identification information is available for provision to the web server; and an identification-information sending part that sends the identification information to the web server if the identification information and the management information are mutually associated and available for the provision. 
     Because the identification-information sending part sends the identification information if the management information and the identification information are mutually associated and if that identification information is available for provision to the web server, the identification information will not be sent to the web server if the management information and the identification information are not mutually associated or if the associated identification information is unavailable for provision. Thus, sending/not sending to the web server may be properly managed depending on the status of the identification information. 
     A call receiving device according to an embodiment of the present invention includes: a call receiving part that receives a call based on identification information that is explicitly or implicitly provided in a web page and that identifies a call receiver; a call-receiver-information receiving part that, if any call receiver is associated with the identification information, receives information of the call receiver, and if no call receiver is associated with the identification information, receives information indicating the absence of call receivers; and a call connection part that, if the information of the call receiver is received, connects the call to the call receiver, and if the information indicating the absence of call receivers is received, renders the call unconnected. 
     According to the embodiment of the present invention, by dynamically allocating identification information for indicating a phone number in a Pay-Per-Call system to individual items of advertisement information and identifying a call receiver, and by enabling the reuse of the identification information, the effective use and the prevention of depletion of the identification information resources may be allowed 
     By dynamically changing the identification information depending on the period of provision to a web page and the number of times of provision, the advertising effectiveness may also be ascertained by period of time or time zone. Also, by extending/reducing a period connected or unconnected to the call receiver depending of the degree of calls based on identification information for which provision to the web page has been terminated, it is possible to accurately ascertain the advertising effectiveness, prevent confusion among users, and further the effective use of identification information resources. 
     Embodiment 1 
     An advertisement information management system S using an information management method according to Embodiment 1 of the present invention will now be described with reference to the drawings. Furthermore, in the present specification, a server means a server computer, and a site (a website and an Internet site are also generally synonymous) means a collective entity of web pages built virtually within the server. A web page can be specified by an URL and is a virtual information-providing medium in which various types of information such as character information and image information are posted. Herein, “posting on a website” is used in a synonymous manner with “posting on a web page”, and “viewing a website” is used in a synonymous manner with “viewing a web page”. 
       FIG. 1  is a schematic diagram illustrating the overall configuration of this advertisement information management system S. This advertisement information management system S is roughly configured with an information management server (information management device)  1  and a call receiving server (call receiving device)  2 , and the information management server  1  is connected to an advertiser&#39;s server  3 , an agent&#39;s server  4 , advertisement providing servers  5   a - 5   c , and a user&#39;s computer  6  via the internet W in a manner that allows for information to be received and sent. The advertiser and the user have an advertiser&#39;s phone  7  and a user&#39;s phone  8 , respectively, which are connected to the call receiving server  2  via a telephone network N. 
     The advertiser&#39;s server  3  is a server computer managed by an advertiser A, and an advertiser&#39;s website (advertiser&#39;s site)  3   a  is built internally as a second Internet site. This advertiser&#39;s site  3   a  is linked to advertisement information  9   a - 9   c  described below and the content of the advertiser&#39;s site  3   a  (detailed information of the advertisement information) will be displayed on the user&#39;s computer  6  when a user U clicks on the advertisement information  9   a - 9   c . Moreover, the advertiser A can send a banner image  9  to the agent&#39;s server  4  via the advertiser&#39;s server  3 . 
     This banner image  9  is, for example, a decorative advertisement image to which various colors and patterns have been added to gather the attention of users, or a descriptive advertisement image that briefly describes the content of the advertisement of the advertiser A. 
     The agent&#39;s server  4  is a server computer managed by the advertising agent and connected to a plurality of advertisement providing servers  5   a - 5   c  via the Internet W, and comprehensively manages these advertisement providing servers  5   a - 5   c . The agent&#39;s server  4  has a function to receive the banner image  9  from the advertiser&#39;s server  3 . Then, the server sends the banner image  9  to the information management server  1  and receives the banner image  9  combined with a script (index information)  21  such as Flash from the information management server  1 . Furthermore, the server also has a function to send the combined banner image  9  as advertisement information  9   a - 9   c  to the plurality of advertisement providing servers  5   a - 5   c . Details of this script  21  are described below. 
     The agent&#39;s server  4  has an internal memory device that is not shown. Inside that memory device, a management ID database  4   a  is built as shown in  FIG. 2 . This management ID database  4   a  is built by mutually associating a management ID (management information)  14  and the banner image  9 . 
     This management ID  14  is information used for accounting management for each item of advertisement information  9   a - 9   c  and is also information that identifies advertisement information  9   a - 9   c . The management ID is composed of an MID (advertiser ID)  14   p , a DID (advertising agent ID)  14   q , a PID (merchandise ID)  14   r , and an SID (advertisement providing site ID)  14   s , for example. Specifically, the management ID  14  allows for identifying advertisement information for merchandise posted on an advertisement providing site managed by an advertising agent. Furthermore, if the management ID  14  includes a UID (personal page ID)  14   t , the management ID allows for identifying advertisement information based on a contract with an advertisement providing site administrator (advertisement provider) and posted on a personal page (or a personal blog, etc). Thus, individual items of the advertisement information  9   a - 9   c  are associated with the management IDs  14   a - 14   c , respectively. 
     The advertisement providing servers (web servers)  5   a - 5   c  are server computers each managed by an advertisement provider, and advertisement providing sites  12   a - 12   c  are built inside each of the servers as first Internet sites.  FIG. 3  is an example of a display screen of a web page of the advertisement providing site  12   a.    
     This advertisement providing site  12   a  is a so-called portal site, and various types of information are posted within the web page. An advertisement frame  13   a  is placed within the web page, and the advertisement information  9   a  received from the agent&#39;s server  4  is posted within the advertisement frame  13   a.    
     The advertisement information  9   a  is configured by combining the banner image  9  with the script  21  and has a function to display the identification information  11   a  to the user U with the functions of the script  21  while gathering the attention of the user U. The identification information  11   a  is information for identifying a call receiver, such as, for example, phone number information “0125423-0011002553” having a total of 17 digits that include a server identification number as the first 7 digits and an advertisement identification number as the second 10 digits. The user U can contact by phone (call) the advertiser A of this advertisement information  9   a  by making a call based on this identification information  11   a.    
     For the method of providing the identification information  11   a  in the advertisement providing site  12   a , several methods are applicable. For example, as shown in  FIG. 3 , there is a method in which the identification information  11   a  is displayed by being posted on the advertisement providing site  12   a  along with the banner image  9 . For example, there is a method in which, as shown in  FIG. 4A , in a normal state (i.e., when the mouse pointer M is not on the banner image  9 ), only the banner image  9  is displayed and the identification information  11   a  is not displayed, and as shown in  FIG. 4B , when the mouse pointer M is moved onto the banner image  9 , the identification information  11   a  is displayed in a balloon. For example, there is a method in which, as shown in  FIG. 5B , in a normal state (i.e., before clicking on the banner image  9  with the mouse), only the banner image  9  is displayed and the identification information  11   a  is not displayed and, as shown in  FIG. 5B , when the banner image  9  is clicked with the mouse, another window appears and the identification information  11   a  is displayed within the window. 
     The advertisement information  9   b ,  9   c  are similarly posted on the advertisement providing sites  12   b ,  12   c  as well. The banner image  9  in the advertisement information  9   b ,  9   c  is common to that in the advertisement information  9   a , and each item of the identification information  11   b ,  11   c  displayed with the functions of the script  21  has a different number. Specifically, the identification information  11   b  has the number “0125423-0011002554” and the identification information  11   c  has the number “0125423-0011002555”. Therefore, ascertaining which number the user U has called allows for ascertaining which of the advertisement information  9   a - 9   c  had advertising effectiveness. 
     Of course, the identification information  11   a - 11   c  is not limited to 17-digit phone number information and may be 2- to 4-digit information that is a part of a phone number or may be an input number of a few digits for the user U to input into the destination server after making the call. Moreover, if the destination server has a voice-recognition function, the identification information  11   a - 11   c  may also be a keyword for the user U to say during the call. As the other configurations of the advertisement providing sites  12   b ,  12   c  are similar to that of the advertisement providing site  12   a , descriptions thereof are omitted. 
     Furthermore, in the present Embodiment 1, it has been described that the agent&#39;s server  4  is managed by the advertising agent and the advertisement providing servers  5   a - 5   c  are managed by the advertisement providers as if they are separate servers, but of course, they do not necessarily have to be separate. For example, one advertising agent may manage the plurality of advertisement providing servers  5   a - 5   c  and eliminate the agent&#39;s server  4 , and each of the advertisement providing servers  5   a - 5   c  may function as the agent&#39;s server. Moreover, based on a contract with the administrator of each of the advertisement providing sites  12   a - 12   c , the advertisement information  9   a - 9   c  may be posted on a plurality of personal pages associated with each of the advertisement providing sites  12   a - 12   c.    
     The user&#39;s computer  6  is a computer managed and used by the user U who views the advertisement providing sites  12   a - 12   c . When the user U views the advertisement providing site  12   a  via the internet W with the user&#39;s computer  6 , the advertisement information  9   a  will be displayed on the display screen of the user&#39;s computer  6  along with various types of information within the advertisement providing site  12   a.    
     Then, when the user U is interested in the advertisement information  9   a  and calls the displayed number “0125423-0011002553” from the user&#39;s phone  8  at home, it is received by the call receiving server  2 , allowing for the phone call to the advertiser A. 
     The information management server  1  is a server computer that configures the principal part of this advertisement information management system S and is connected to the agent&#39;s server  4  via the Internet W. This information management server  1  executes the operation to combine the banner image  9  received from the agent&#39;s server  4  with the script  21  and return the combined banner image  9  to the agent&#39;s server  4 . Furthermore, it also executes the operation to acquire request signals for the identification information  11   a - 11   c  along with information of the management IDs  14   a - 14   c  from the advertisement providing servers  5   a - 5   c . Based on the request signals, it also executes an operation to dynamically allocate and send the identification information  11   a - 11   c  to the advertisement providing servers  5   a - 5   c  corresponding to the management IDs  14   a - 14   c  based on the status thereof. Furthermore, when receiving the identification information  11   a - 11   c  from the call receiving server  2  described below, it also executes an operation to send information indicating the status of the identification information  11   a - 11   c  to the call receiving server  2 . 
       FIG. 6  is a block diagram showing an overview of the internal configuration of this information management server  1 . The information management server  1  internally has a central processing unit (CPU)  15  and the memory device  16 . This CPU  15  executes each operation described above as the principal part of the computer. 
     In the memory device  16 , an information management program P, information management database D, and identification information database E are stored. Each operation described above is executed by the CPU  15  based on instructions from this information management program P. Specifically, with the information management program P, the CPU  15  functions as a script combining part  15   a , a management ID acquisition part (management-information acquisition part)  15   b , a first determination part  15   c , a second determination part  15   d , an identification-information-association executing part  15   e , an identification-information sending part  15   f , a sending-status changing part  15   g , a connection-status changing part  15   h , a call-reception-information receiving part  15   j , and a period changing part  15   k . The functions of each part and operations thereof will now be described as follows with reference to  FIG. 7 . 
     The script combining part  15   a  has a function to combine the predefined script  21  with the banner image  9  received from the agent&#39;s server  4  and return it to the agent&#39;s server  4 . The banner image  9  combined with the script  21  is sent as the advertisement information  9   a - 9   c  from the agent&#39;s server  4  to the plurality of advertisement providing servers  5   a - 5   c.    
     The script  21  is an operation module that is composed of Flash, etc., and has a function to send a request signal for the identification information  11  to the information management server  1  and display the identification information  11  from the information management server  1  within a web page. Specifically, when a web page of the advertisement providing sites  12   a - 12   c  is viewed by the user U, based on the function of the script  21  in the advertisement information  9   a - 9   c  posted on the web page, the identification information  11   a - 11   c  received from the information management server  1  will be displayed within the web page. 
     The management ID acquisition part  15   b  has a function to acquire the management IDs  14   a - 14   c  sent from the advertisement providing servers  5   a - 5   c . For example, if the user U accesses the advertisement providing site  12   a  using the user&#39;s computer  6 , based on the function of the script  21  in the advertisement information  9   a , a request signal for identification information is sent from the advertisement providing server  5   a  to the information management server  1 . In doing so, from the advertisement providing server  5   a , the management ID  14   a  of the advertisement information  9   a  is sent to the information management server  1  along with the request signal and the management ID  14   a  is acquired by the management ID acquisition part  15   b . The management ID acquisition part  15   b  sends information of the acquired management ID 14  to the first determination part  15   c  and the second determination part  15   d.    
     The first determination part  15   c  has a function to determine whether the acquired management ID  14   a  is mutually associated with any identification information. As this determination function is performed by using the information management database D, the information management database D will now be described as follows. 
       FIG. 8  is a data structure diagram showing an overview of the internal structure of the information management database D. The information management database D is built with the management ID  14 , identification information  11 , and status information  17  that are each mutually associated. In this information management database D, for example, if the identification information  11   a  is associated with the management ID  14   a , it means that a call receiver indicated by the management ID  14   a  (i.e., the advertiser&#39;s phone  7  of the advertiser A) and the identification information  11   a  are mutually associated. 
     Herein, the status information  17  is information indicating various statuses of the identification information  11  and has sending-status information  17   a  and connection-status information  17   b , for example. If the sending-status information  17   a  is “1”, this indicates a status in which it is possible to send the identification information  11  to the advertisement providing servers  5   a - 5   c . If the sending-status information  17   a  is “0”, this indicates a status in which it is not possible to send the identification information  11  to the advertisement providing servers  5   a - 5   c.    
     Moreover, if the connection-status information  17   b  is “1”, this indicates a status in which a call based on the identification information  11  can be connected to a call receiver indicated by the management ID  14  associated with the identification information  11 . If the connection-status information  17   b  is “0”, this indicates a status in which a call based on the identification information  11  cannot be connected to a call receiver indicated by the management ID  14  associated with the identification information  11 . For example, if the identification information  11   a  is associated with the management ID  14   a  and if the connection-status information  17   b  thereof is “1”, a call based on the identification information  11   a  will be connected to the advertiser&#39;s phone  7  of the advertiser A indicated by the management ID  14   a.    
     In addition, in the information management database D, if the sending-status information  17   a  of the identification information  11  is “1”, the connection-status information  17   b  is always “1”, whereas if the sending-status information  17   a  is “0”, the connection-status information  17   b  may be “1” or “0”. Moreover, a plurality of items of identification information  11  may be associated with one management ID  14 , among which there is always one identification information  11  whose sending-status information  17   a  is “1” while the sending-status information  17   a  of the other items of identification information  11  is “0”. 
     Within the identification information database E in the memory device  16 , as shown in  FIG. 9 , the plurality of items of identification information  11  have been stored without being associated with either the management ID  14  or a call receiver in advance. When particular identification information  11   a  among them is associated with a particular management ID  14   a  by the identification-information-association executing part  15   e , in the information management database D, the identification information  11   a  will be set to be associated with the management ID  14   a , and the sending-status information  17   a  and the connection-status information  17   b  are set for the identification information  11   a  by the sending-status changing part  15   g  and the connection-status changing part  15   h . Then, when the association between the management ID  14   a  and the identification information  11   a  is removed by the identification-information-association executing part  15   e , the identification information  11   a  associated with the management ID  14   a  in the information management database D will be deleted. Then, if all of the identification information  11   a  is deleted from the information management database D, the identification information  11   a  will again be stored into the identification information database E. Subsequently, when another management ID  14   b  and the identification information  11   a  are mutually associated in this case, the identification information  11   a  will be set in a field corresponding to the management ID  14   b  in the information management database D. 
     The plurality of items of the identification information in this identification information database E may be stored without being associated with either the management ID  14  or a call receiver; however, for example, an association with a call receiver (i.e., an advertiser) alone may be made in advance. For example, in a case in which 1,000,000,000 types of identification information are stored, 200,000,000 types of identification information may be allocated to 5 call receivers (advertisers) each in advance. In that case, when the identification-information-association executing part  15   e  described below extracts the identification information from this identification information database E, based on information of the call receiver (advertiser) indicated by the management ID  14 , it will extract one item of identification information from the information allocated to the call receiver. 
     The first determination part  15   c  determines the presence or absence of the identification information  11  associated with the management information ID  14   a  by referring to the information management database D, and if there is associated identification information  11  (identification information  11   a  in the present embodiment), it sends information indicating “presence of identification information” to the second determination part  15   d . If there is no identification information  11  associated with the management ID  14   a , it sends information indicating “absence of identification information” to the identification-information-association executing part  15   e.    
     The second determination part  15   d  has a function to determine whether the identification information  11  is available for provision to the web server. Specifically, if it receives information indicating “presence of identification information” from the first determination part  15   c , it confirms the sending-status information  17   a  of the identification information  11   a  associated with the management ID  14   a  by referring to the information management database D. Then, if the sending-status information  17   a  of the identification information  11   a  is “1” (i.e., indicating a status available for sending), it sends information indicating “available for sending” to the identification-information sending part  15   f.    
     On the other hand, if the sending-status information  17   a  of all of the identification information  11  associated with the management ID  14   a  is “0”, it sends information indicating “unavailable for sending” to the identification-information-association executing part  15   e.    
     The identification-information-association executing part  15   e  has a function to associate the identification information  11  with the management ID  14  if the identification information  11  and the management ID  14  are not mutually associated. Specifically, when it receives information indicating “absence of identification information” from the first determination, it extracts new identification information  11   a  associated with neither the management ID  14  nor a call receiver from the identification information database E and associates it with the management ID  14   a.    
     In addition, when new identification information  11   a  is associated with the management ID  14   a  by the identification-information-association executing part  15   e , both the sending-status information  17   a  and the connection-status information  17   b  of the identification information  11   a  are set to “1” by the sending-status changing part  15   g  and the connection-status changing part  15   h . Then, the identification-information-association executing part  15   e  sends information indicating “presence of identification information” and “available for sending” to the identification-information sending part  15   f.    
     Moreover, the identification-information-association executing part  15   e  also has a function to associate other identification information  11   e  different from the identification information  11  with the management ID  14  if the identification information  11  is unavailable for provision to the advertisement providing servers  5   a - 5   c . Specifically, when it receives information indicating “unavailable for sending” form the second determination part  15   d , it extracts other identification information  11   e  that is different from the identification information  11   a  and is associated with neither the management ID  14  nor a call receiver but associated with the management ID  14   a  from the identification information database E and associates it with the management ID  14   a.    
     In addition, when the management ID  14   a  is associated with other identification information  11   e  by the identification-information-association executing part  15   e , both the sending-status information  17   a  and the connection-status information  17   b  of other identification information  11   e  are set to “1” by the sending-status changing part  15   g  and the connection-status changing part  15   h . Then, the identification-information-association executing part  15   e  sends information indicating “presence of identification information” and “available for sending” to the identification-information sending part  15   f.    
     The identification-information sending part  15   f  has a function to send the identification information  11  to the advertisement providing servers  5   a - 5   c  if the identification information  11  and the management ID  14  are mutually associated and available for provision. Specifically, if receiving information indicating “available for sending” from the second determination part  15   d , or if receiving information indicating “presence of identification information” and “available for sending” from the identification-information-association executing part  15   e , it sends the identification information  11  that is associated with the management ID  14   a  and available for sending to the advertisement providing server  5   a  indicated by the management ID  14   a.    
     If the user U accesses the advertisement providing site  12   a  through this series of functions and operations by the CPU  15 , the identification information associated with the management ID  14   a  and rendered available for sending at that point will be dynamically sent to the advertisement providing server  5   a  and displayed on the advertisement providing site  12   a.    
     In addition, in the present Embodiment 1, in both cases in which the first determination part  15   c  determines “absence of identification information” and in which the second determination part  15   d  determines “unavailable for sending”, the identification-information-association executing part  15   e  is configured to associate new identification information  11  with the management ID  14   a . However, it is also possible for information indicating “absence of identification information” by the first determination part  15   c  and information indicating “unavailable for sending” by the second determination part  15   d  to be configured to be sent to the identification-information sending part  15   f , and in those cases, the identification information is not sent to the advertisement providing server  5   a.    
     Next, each function of the sending-status changing part  15   g , the connection-status changing part  15   h , the call-reception-information receiving part  15   j , and the period changing part  15   k  will now be described using the explanatory diagram of statuses shown in  FIG. 10 .  FIG. 10  is an explanatory diagram of statuses for describing each status of the identification information  11   a.    
     The sending-status information  17   a  indicated by (a) in the figure is, as described above, information indicating whether the identification information  11   a  is available for sending to the advertisement providing server  5   a  when there is a request signal from the advertisement providing server  5   a . The “1” status of this sending-status information  17   a  indicating that it is available for sending and the “0” status indicating that it is unavailable for sending are set and changed based on the function of the sending-status changing part  15   g.    
     The connection-status information  17   b  indicated by (b) is information indicating whether a call based on the identification information  11   a  is available for a call connection to a call receiver. The “1” status of this connection-status information  17   b  indicating that it is available for connection and the “0” status indicating that it is unavailable for connection are set and changed based on the function of the connection-status changing part  15   h . Herein, a call receiver refers to an advertiser&#39;s contact destination (advertiser&#39;s phone  7 ) indicated by the management ID  14   a  associated with the identification information  11   a . Specifically, if the identification information  11   a  is associated with the management ID  14   a , the call receiver is the advertiser&#39;s phone  7  (first call receiver), but if the identification information  11   a  is associated with another new management ID  14   d , the call receiver will be another call receiver (second call receiver) different from the advertiser&#39;s phone  7 . 
     The status of association with the management ID  14  indicated by (c) is a status indicating whether the identification information  11   a  is associated with the management ID. Specifically, “Y” is a status in which the identification information  11   a  is associated with any item of management ID  14  and the identification information  11   a  is not in the identification information database E but in the information management database D. Conversely, “N” is a status in which the identification information  11   a  is associated with none of the items of management ID  14  and the identification information  11   a  is in the identification information database E and not in the information management database D. 
     The extraction signal indicated by (d) is a signal representing an extracting operation from within the identification information database E by the identification-information-association executing part  15   e . When this extraction signal is turned “ON”, the identification information  11   a  is extracted from within the identification information database E and associated with the management ID  14 , and both the sending-status information  17   a  and the connection-status information  17   b  of the identification information  11   a  are set to “1”. 
     For example, if the user U accesses the advertisement providing site  12   a  during a published period T 1  in the figure, the identification information  11   a  is associated with the management ID  14   a  and made available for sending and connection, and the identification information  11   a  is therefore displayed on the advertisement providing site  12   a . Then, a call based on the identification information  11   a  is connected to the advertiser&#39;s phone  7 . 
     However, if the user U accesses the advertisement providing site  12   a  during an unpublished period (predefined period) T 2  in the figure, the identification information  11   a  is associated with the management ID  14   a  but unavailable for sending, and the identification information  11   a  is therefore not sent to the advertisement providing server  5   a . At this time, other identification information  11   e  extracted by the identification-information-association executing part  15   e  is sent to the advertisement providing server  5   a . Because the identification information  11   a  is unavailable for sending but available for connection during this unpublished period T 2 , if a call based on the identification information  11   a  is made, that call is connected to the advertiser&#39;s phone  7  as the first call receiver. In addition, the published period T 1  and unpublished period T 2  are collectively referred to as a period available for connection T 12 . 
     If the user U accesses the advertisement providing site  12   a  during a disabled period T 3  in the figure, the identification information  11   a  is associated with the management ID  14   a  but unavailable for sending and unavailable for connection. Therefore, the identification information  11   a  is not sent to the advertisement providing server  5   a , and a call based on the identification information  11   a  is rendered unavailable for connection (busy, on hold, announcement of failed connection, etc.). In addition, other identification information  11   e  is displayed on the advertisement providing site  12   a.    
     Moreover, the case in which the user U accesses the advertisement providing site  12   a  during a dissociated period T 4  is similar to the case of the disabled period T 3 . However, in this dissociated period T 4 , the association between the management ID  14   a  and the identification information  11   a  is removed and the identification information  11   a  is deleted from the information management database D and stored into the identification information database E. Therefore, the identification information  11   a  is available for association with any management ID  14  and call receiver based on a request signal from other advertisement providing servers. In addition, the disabled period T 3  and the dissociated period T 4  are collectively referred to as a period unavailable for connection T 34 . 
     In addition, these respective periods T 1 -T 4  may be set at any time or period. Moreover, particularly for the published period T 1 , etc., they may be set not on the basis of time but on the basis of the number of accesses to the advertisement providing server  5   a  (i.e., the number of times the identification information  11   a  is sent to the advertisement providing server  5   a ). 
     During this dissociated period T 4 , when extraction of the identification information  11   a  by the identification-information-association executing part  15   e  (X in the figure) is executed and an association with a new management ID (new management information)  14   d  is made, the identification information  11   a  will be sent to an advertisement providing server indicated by the new management ID  14   d , and a call based on the identification information  11   a  will be connected to a second call receiver indicated by the new management ID  14   d.    
     The call-reception-information receiving part  15   j  has a function to receive call-reception information  18  indicating that there was a call based on the identification information  11   a  from the call receiving server  2 . Then, based on the information management database D, it returns information of the call receiver associated with the identification information  11   a  and rendered available for connection to the call receiving server  2 . 
     Specifically, if there is no identification information  11   a  in the information management database D, or if there is the identification information  11   a  but its connection-status information  17   b  is “0”, it returns information indicating “unavailable for connection” to the call receiving server  2 . On the other hand, if there is the identification information  11   a  in the information management database D and its connection-status information  17   b  is “1”, it returns the phone number information of the advertiser&#39;s phone  7  as the call receiver based on the management ID  14   a  associated with the identification information  11   a.    
     The period changing part  15   k  has a function to extend the unpublished period T 2  if there is a call based on the identification information  11   a  during the unpublished period (predefined period) T 2  between changing the status of the identification information  11   a  into being unavailable for sending and changing the status into being unavailable for a call connection to the advertiser&#39;s phone  7 . Specifically, if the call-reception-information receiving part  15   j  receives the call-reception information  18  based on the identification information  11   a  during the unpublished period T 2 , it extends the period in which the call can be connected to the advertiser&#39;s phone  7  based on the judgment that the advertising effectiveness of the advertisement information  9   a  associated with the identification information  11   a  remains. 
     For example, it is also possible to configure the unpublished period T 2  to be reduced if there is no call based on the identification information  11   a  at all at a particular point (e.g., intermediate point) within the unpublished period T 2 . 
     Moreover, the period changing part  15   k  has a function to extend the period unavailable for connection T 34  if there is a call based on the identification information  11   a  during the period unavailable for connection T 34  between changing the status of the identification information  11   a  into being unavailable for a call connection to the advertiser&#39;s phone  7  and changing the status into being available for a call connection to the second call receiver. In particular, if the call-reception-information receiving part  15   j  receives the call-reception information  18  based on the identification information  11   a  during the disabled period T 3 , it extends the disabled period T 3  in which the call cannot be connected the based on the judgment that it is too early to associate the identification information  11   a  with a new call receiver. 
     For example, it is also possible to configure the disabled period T 3  to be reduced if there is no call based on the identification information  11   a  at all at a particular point (e.g., intermediate point) within the disabled period T 3 . 
     The call receiving server  2  is a server computer for receiving a call from a user&#39;s phone  8  of the user U and is connected to the information management server  1  and the telephone network N. The user&#39;s phone  8  and the advertiser&#39;s phone  7  of the advertiser A are also connected to this telephone network N, allowing a call to be made from the user U to the advertiser A via the call receiving server  2 . 
     The call receiving server  2  has an internal central processing unit (CPU) that is not shown, and that CPU functions as a call receiving part, an input-information extracting part, an information sending part, a call-receiver-information receiving part, and a call connection part. 
     The call receiving part has a function to receive the call from the user&#39;s phone  8 . Specifically, when the user U who has viewed the advertisement providing site  12   a  inputs the identification information  11   a  (17-digit phone number information “0125423-0011002553”) displayed on a site page into the user&#39;s phone  8 , a call is made to the call receiving server  2  based on the first 7-digit server identification number. The call receiving part recognizes the call without receiving it and acquires information of the input 17-digit phone number “0125423-0011002553”. As the call receiving part does not receive the call, the user U may make the phone call smoothly as if they had directly called the call receiver without becoming aware of the relay of the call receiving server  2 . 
     The input-information extracting part has a function to extract the phone number information as the input information  19  when it receives the phone number information from the call receiving part. In the present Embodiment 1, all of the 17 digits of the phone number information input in the user&#39;s phone  8  by the user U are extracted as the input information  19 , but of course, a part of the phone number information may be extracted as the input information  19 , or voice information stated by the user U based on information such as a keyword may be extracted as the input information  19 . 
     For example, when the user U inputs the first 7-digit server identification number to make a call, the call receiving server  2  receives it, and if the second 10-digit advertisement identification number is input during the automatic response, the advertisement identification number may be extracted as the input information  19  by the input-information extracting part. 
     Moreover, in cases in which the call receiving server  2  has a voice-recognition function, the user U says a keyword as the input information  19  during the automatic response and the voice information may thereby be extracted as the input information  19  by the input-information extracting part. For example, when the user U says “0011002553” on the phone, the advertisement identification number for the call may be recognized to be “0011002553”. 
     Furthermore, in the present Embodiment 1, in cases in which the phone number information as the identification information  11   a  is “0125423-0011002553”, in which the phone number information as the identification information  11   b  is “0125423-0011002554”, and in which the phone number information as the identification information  11   c  is “0125423-0011002555”, the advertiser&#39;s phone  7  of the advertiser A will be the call receiver. Then, it is possible to ascertain which of the advertiser&#39;s phone  7  was based on for the user U to make a call based on the differences in the numbers of the phone number information, specifically the final digit. 
     The information sending part has a function to send the input information  19  extracted by the input-information extracting part along with the call-reception information  18  to the information management server  1 . The input information  19  and the call-reception information  18  are received by the call-reception-information receiving part  15   j.    
     The call-receiver-information receiving part  15   j  has a function to receive information of the call receiver if any call receiver is associated with the identification information  11   a  corresponding to the input information  19 , and to receive information indicating the absence of call receivers if no call receiver is associated with the identification information  11   a . Specifically, if the identification information  11   a  corresponding to the input information  19  is associated with the management ID  14   a  and the connection-status information  17   b  of the identification information  11   a  is “1”, the phone number information of the advertiser A as the call receiver indicated by the management ID  14   a  is received. On the other hand, if the identification information  11   a  is not associated with any management ID  14 , or if it is associated with the management ID  14  but its connection-status information  17   b  is “0”, index information indicating “unavailable for connection” corresponding to the absence of call receivers is received. 
     The call connection part connects a call to the advertiser&#39;s phone  7  if the information received by the call-receiver-information receiving part  15   j  is information of the call receiver (phone number information of the advertiser A). On the other hand, it renders the call unconnected if the information received by the call-receiver-information receiving part  15   j  is information indicating “unavailable for connection”. 
     Furthermore, in the present Embodiment 1, an example has been described that is configured so that the call receiving server  2  extracts the input information in the call and sends the input information to the information management server  1 , but of course, it may be configured so that the information management server  1  has an input-information extracting part and when it receives call information from the call receiving server  2 , it extracts the input information from the information. 
     Moreover, in the present Embodiment 1, an example has been described in which the information management server  1  and the call receiving server  2  are configured as separate bodies, but of course, they may be configured so that the functions of both are implemented with one server computer. Furthermore, one server computer may function as the agent&#39;s server  4  as well as the information management server  1  and the call receiving server  2 . 
     Next, the operations of the advertisement information management system S using the advertisement information management method according to this Embodiment 1 will be described using the flow charts shown in  FIGS. 11 and 12 . 
     First, the procedure before the identification information  11  is displayed within the web page when the user U views the advertisement providing site  12   a  is described using  FIG. 11 . The advertiser&#39;s server  3  sends the banner image  9  to the agent&#39;s server  4  based on the request for posting an advertisement from the advertiser A (S.  1 ). The agent&#39;s server  4  sends the received banner image  9  to the information management server  1  (S.  2 ). The information management server  1  combines the script  21  with the received banner image  9  and sends it to the agent&#39;s server  4  (S.  3 ). 
     The agent&#39;s server  4  associates the received and combined banner image  9  with the plurality of the management IDs  14   a - 14   c  as the plurality of items of the advertisement information  9   a - 9   c  (S.  4 ) and sends the advertisement information  9   a - 9   c  to advertisement providing servers  5   a - 5   c , respectively (S.  5 ). 
     The advertisement providing servers  5   a - 5   c  post the received advertisement information  9   a - 9   c  on web pages of the advertisement providing sites  12   a - 12   c , respectively (S.  6 ). 
     When the user U accesses the advertisement providing server  5   a  using the user&#39;s computer  6  and views the advertisement providing site  12   a , the management ID  14   a  and the request signal are sent to the information management server  1  by the function of the script  21  of the advertisement information  9   a  (S.  7 ). At the information management server  1 , it is determined whether the identification information  11   a  is associated with the management ID  14   a  (S.  8 ). Then, if the identification information  11   a  is associated with the management ID  14   a  (S.  8 ), the sending-status information  17   a  of the identification information  11   a  is determined (S.  9 ). If the sending-status information  17   a  of the identification information  11   a  is “1” (S.  9 ), the identification information  11   a  is sent to the advertisement providing server  5   a  (S.  10 ) and the identification information  11   a  is displayed on the web page of the advertisement providing site  12   a.    
     Even in cases in which the identification information  11   a  is associated with the management ID  14   a  (S.  8 ), if the sending-status information  17   a  of the identification information  11   a  is “0” (S.  9 ), other identification information  11   e  different from the identification information  11   a  is extracted from the identification information database E (S.  11 ), the identification information  11   e  is sent to the advertisement providing server  5   a  (S.  12 ), and the identification information  11   e  is displayed on the web page of the advertisement providing site  12   a . Of course, in this case, if other identification information  11   d  separate from the identification information  11   a  is associated with the management ID  14   a  and the sending-status information  17   a  of the identification information  11   d  is “1”, the identification information  11   d  is sent to the advertisement providing server  5   a  without extracting the identification information  11   e.    
     If no identification information including the identification information  11   a  is associated with the management ID  14   a  (S.  8 ), new identification information  11   a  is extracted from the identification information database E (S.  13 ), the identification information  11   a  is sent to the advertisement providing server  5   a  (S.  14 ), and the identification information  11   a  is displayed on the web page of the advertisement providing site  12   a.    
     Subsequent processing of a call connection by the user U who has seen the identification information  11   a  will be described using  FIG. 12 . Based on the identification information  11   a  displayed within the web page of the advertisement providing site  12   a , the user U inputs the input information  19  into the user&#39;s phone  8  to make a call (S.  31 ). The call receiving server  2  receives the call and extracts the input information  19  (S.  32 ). The call receiving server  2  sends the extracted input information  19  and the call-reception information  18  to the information management server  1  (S.  33 ). 
     The information management server  1 , based on the received input information  19 , checks whether the identification information  11   a  corresponding to the input information  19  is associated with the management ID  14  (S.  34 ) and confirms the connection-status information  17   b  of the identification information  11   a  (S.  35 ). Then, if the identification information  11   a  is associated with the management ID  14  (S.  34 ) and its connection-status information  17   b  is “1” (S.  35 ), the call receiver information (phone number information of the advertiser A) is returned to the call receiving server  2  (S.  36 ). Then, the call receiving server  2 , based on the returned call receiver information, connects the call from the user U to the advertiser&#39;s phone  7  (S.  37 ). 
     If the identification information  11   a  is not associated with the management ID  14  (S.  34 ), or if the connection-status information  17   b  of the identification information  11   a  is “0” (S.  35 ), the information management server  1  returns information indicating “unavailable for connection” to the call receiving server  2  (S.  38 ). The call receiving server  2  processes the call from the user U as unconnected (processing as busy, processing to place the call on hold, processing to announce a failure to connect, etc.) (S.  39 ). 
     Embodiment 2 
       FIG. 13  is a schematic diagram showing the overall configuration of an advertisement information management system S′ using the information management method according to Embodiment 2 of the present invention. Furthermore, in the present Embodiment 2, configurations similar to those in Embodiment 1 are provided with the same symbols and the descriptions thereof are omitted. 
     This Embodiment 2 describes the advertisement information management system S′ that addresses cases in which the functions of the script  21  cannot be used in the advertisement providing sites  12   a - 12   c , for example if the advertisement providing sites  12   a - 12   c  are cell-phone sites. 
     In this Embodiment 2, when the agent&#39;s server  4  receives the banner image  9  from the advertiser&#39;s server  3 , processes to link the banner image  9  to landing pages  1   a - 1   c  built within the information management server  1  are performed, and the banner image  9  is associated with the management IDs  14   a - 14   c  and sent to the advertisement providing servers  5   a - 5   c , respectively. Therefore, a process for combining the script  21  with the banner image  9  is not performed by the information management server  1 . 
     On the other hand, within the information management server  1 , the landing pages  1   a - 1   c  corresponding to the managements ID  14   a - 14   c , respectively, are built. These landing pages  1   a - 1   c  are web page with the script  21  embedded therein. For example, when the landing page  1   a  is accessed based on the link from the advertisement information  9   a , information of the management ID  14   a  and a request signal will be sent to the management ID acquisition part  15   b  of CPU  15  based on the function of the script  21  in the landing page  1   a . Therefore, in the landing page  1   a , the identification information  11   a  associated with the management ID  14   a  will be displayed. 
     Of course, instead of building separate landing pages  1   a - 1   c  that each correspond to each advertisement information  9   a - 9   c , a single landing page  1   a  accessed with the link from the plurality of items of the advertisement information  9   a - 9   c  may be built to provide a configuration in which each of corresponding management IDs  14   a - 14   c  is sent from the advertisement providing servers  5   a - 5   c  on which each item of advertisement information  9   a - 9   c  is posted upon access to the landing page  1   a . This allows the landing page  1   a  to properly display the identification information  11   a - 11   c  corresponding to the received management IDs  14   a - 14   c.    
     Preferred embodiments of the present invention have been described above, but the present invention is not limited to these, and it is possible to make various modifications and changes within the scope of the invention. 
     For example, in Embodiments 1 and 2, configurations have been described in which the advertiser&#39;s site  3   a  is liked to the advertisement information  9   a - 9   c  and the content of the advertiser&#39;s site  3   a  is displayed on the user&#39;s computer  6  by clicking on the advertisement information  9   a - 9   c , but this advertiser&#39;s site  3   a  is not an essential requirement. Specifically, in Embodiment 1, the location to which the advertisement information  9   a - 9   c  is linked may be a site other than the advertiser&#39;s site  3   a  (a site managed by others than the advertiser A), and even if the advertisement information  9   a - 9   c  does not link to any site, it falls within the scope of the present invention. 
     Of course, in this case, the banner image  9  is not sent from the advertiser&#39;s site  3   a  to the agent&#39;s server, but the banner image  9  may be sent from another site described above to the agent&#39;s server  4 , or the banner image  9  may be generated within the agent&#39;s server  4 . 
     Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
