Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a telephone service method, telephone service apparatus and telephone service program for providing a certain service when receiving a telephone call. 
     2. Description of the Related Art 
     In the past, when dialing another party by a telephone to call a mobile phone or regular phone of that party, the other party sometimes will not answer the phone for some reason or another. In such a case, one has continue ringing until the other party answers the phone or ends up being switched to an answering service function, listens to the message, and then records one&#39;s own message after the beep. 
     In the case of an audible ringing signal, the audible ringing signal remains the same at all times. In the case of an answering service function, the message indicating that the answering service function has begun, for example, “I can&#39;t come to the phone now . . . ”, runs, a beep is given, and then recording is begun. 
     In the above way, in a conventional telephone, one could only hear the same audible ringing signal continuously when calling up another party. The caller therefore wasted his or her time. 
     Alternatively, after continuously ringing for a certain time, the answering service function kicked in and a message indicating that the function started ran. Therefore the caller had to listen to the same fixed information again and again. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a telephone service method and apparatus which refer to a table when a phone call is made and when the number called is registered, send another message in place of the audible ringing signal or answering service announcement message, and return cash to the called user or the calling user. 
     To attain the above object, the telephone service method of the present invention comprises the steps of receiving a request for line connection from a phone of a caller, determining an identifier of a phone of a called party for which line connection is requested, judging whether the identifier of the called party is registered in a management table linking called party identifiers and business advertisements, and, when judging that the identifier of the called party is registered, sending a business advertisement linked with that identifier from business advertisements stored in a content database to the phone of the caller.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Preferred embodiments of the present invention will be described in detail below while referring to the attached figures. 
     The means for achieving the object of the present invention will be explained first with reference to  FIGS. 1A and 1B . In  FIGS. 1A and 1B , the telephone  1  is a telephone (including mobile phones) which a user uses to make a call. 
     A processing apparatus  2  performs various processing in accordance with a set program. Here, it is comprised of a call sending and receiving means  3  and a customer master  22 . The call sending and receiving means  3  sends and receives calls or sends messages. The customer master  22  is registered with telephone numbers of called parties. 
     Next, the operation will be explained. When receiving a call from a phone  1  of a caller, the call sending and receiving means  3  of the processing apparatus  2  refers to the customer master (table)  22 . When the number of the called party is registered, it sends a message out in place of an audible ringing signal or answering service announcement. It also stores the number of the called party etc. as a log when sending out a message. 
     That is, when receiving a phone call, it judges whether the number of the called party is registered in the customer master  22 , sends out a message when judging that it is registered, and stores the number of the called party as a log when sending out that message. 
     The number of the caller is stored as a log only when the sending time of the message exceeds a predetermined length. Further, the message sent is switched to another message according to the season, date and time, day of the week, etc. set in the table (master) linked with the messages. 
     Cash is returned to the called parties and callers based on phone numbers stored in the log. 
     Next, an embodiment of the present invention and its operation will be successively explained using the attached drawings. 
       FIG. 1  is a view of the overall layout of  FIGS. 1A and 1B .  FIGS. 1A and 1B  are views of the system configuration of the present invention. 
     In  FIGS. 1A and 1B , the telephone  1  is a phone by which a user places a call (including mobile phones), that is, a phone (terminal) for the transfer of a voice signal or data by wired or wireless connection. 
     The processing apparatus  2  performs various processing in accordance with a set program. Here, it is comprised of a call sending and receiving means  3 , an announcement message broadcasting means  4 , an answering service recording means  5 , a billing means  6 , a customer information and stock information linking means  13 , a CM stock registering and cashback amount registering means  17 , a customer master  22 , a phone usage log file  25 , announcement content  27 , etc. 
     The call sending and receiving means  3  sends and receives audio data of calls of a caller and a called party, sends normal audible ringing signals or answering service announcements or messages in place of the same etc. (explained later using  FIGS. 2A  to  2 D to  FIGS. 8A  to  8 F). 
     The message broadcasting means  4  sends the usual message of an answering service function or, when the conditions match, a message in place of the same. 
     The answering service recording means  5  records content as in a usual answering service function. 
     The billing means  6  calculates the cash to be returned to the customers of the calling or called phone numbers based on the phone usage log file  25 , customer master  22 , etc. and prepares bills including the cashback amounts. Here, it prepares a customer cashback list  7 , a stock cashback list  9 , etc. Further, it performs processing for billing the expenses for the cashback service to the content preparers (agents). 
     The customer cashback list  7  is a list of the amounts of cash to be returned to the calling and called customers when messages are sent. A customer billing system  8  of the carrier subtracts the amounts of cash from the amounts billed to the customers of that carrier (carrier providing the communications network to the customers) based on the customer cashback list and prepares bills for the remaining amounts. 
     The stock cashback list  9  is a list of the amounts of cash to be returned for each message (stock) sent to customers. An agent billing system  10  of the carrier prepares bills for the transmission of stock (messages) based on the stock cashback list  9 . 
     A user  11  uses the Internet or i-mode  12  to register membership information or a selected message (register as customer in customer CM master  22 ). 
     The customer information and stock information linking means  13  links the customer information and stock (messages to be sent) (see FIG.  8 B). 
     An operator  14  of the carrier registers customers who apply to receive the cashback service for listening to messages on the phone in the customer CM master  22 . 
     The content preparer (agent)  15  prepares content (messages or commercials etc. to be sent). 
     A content input means  16  inputs the content, cashback conditions, etc. through the Internet. 
     The CM stock registering and cashback registering means  17  registers the content input from the content input means  16  and the amounts of cash to be returned by linking with each other. 
     A cashback means  20  calculates the amounts of cash to be returned in accordance with the amounts of messages which customers of telephone numbers placing calls listen to. 
     The customer master  22  is registered with (updates) the CM numbers, rate systems, cashback amounts, etc. linked with the customers (see later explained FIG.  8 B). 
     The phone usage log file  25  stores logs of usage of phones sent content in place of ordinary audible ringing signals or announcement messages (see later explained  FIG. 8E ) 
     The announcement content  27  is a content database formed by registration of prepared content taking the place of ordinary audible ringing signals or answering service announcements. 
     A telephone  31  is the phone of the called party to which a call is placed by the telephone  1 . Illustration of the network between the telephone  1  and the processing apparatus  2 , the network between the processing apparatus  2  and the telephone  31 , the exchange, etc. is omitted. 
     Next, the operation when a user uses the telephone  1  to dial a number and place a call through the processing apparatus  2 , under the configuration of  FIGS. 1A and 1B , will be explained in detail in accordance with the flow charts of  FIGS. 2A  to  2 D. 
       FIG. 2  is a view of the overall layout of  FIGS. 2A  to  2 D.  FIGS. 2A  to  2 D are flow charts of the call receiving processing of the present invention.  FIGS. 2A and 2B  are overall flow charts. 
     In  FIGS. 2A and 2B , at step S 1 , a user places a call. This is done by the calling user of  FIG. 1A  dialing the phone  1  to place a call which is then routed through the processing apparatus  2  (that is, picking up the receiver and dialing the phone number). 
     At step S 2 , a not shown called phone position judging means judges if the called phone is out of the service area. That is, it judges if it is out of the service area when receiving the call of step S 1  and calling up the telephone of that number (in a mobile phone, when it is not in an area reached by the radio waves or when the power is turned off). When YES, that is, the phone is judged to be out of the service area, the routine proceeds to step S 11 , from which the routine proceeds to the answering service number announcement processing (answering service announcement processing of  FIGS. 3A  to  3 D), where the routine ends. On the other hand, when NO at step S 2 , that is, the phone is judged to be in the service area, the routine proceeds to step S 3 . 
     At step S 3 , the called number is searched for from the telephone numbers registered in the customer CM master  22 . 
     At step S 4 , it is judged if the customer number (called telephone number) is registered in the customer CM master  22 . When YES, that is, it is judged that the customer number is registered, the routine proceeds to step S 5 . When NO, that is, it is judged that the customer number is not registered and therefore the called customer has not registered that it wishes to obtain cash back in return for running a message (content), the routine proceeds to step S 12 , where an ordinary audible ringing signal is sent to the calling phone  1 . The routine then ends. 
     At step S 5 , a new phone usage log file  25  is prepared. This stores the phone number of the called party, the phone number of the caller, the CM No. of the customer CM master, and the starting date. 
     At step S 6 , the registered message of the customer is read and broadcast. That is, the apparatus reads the registered message (content, commercial, etc.) of the CM number registered linked in the customer master  22  of FIG.  8 B and broadcasts (sends) it to the phone  1  of the calling customer instead of the usual audible ringing signal to play it to the calling customer. 
     At step S 7 , it is judged if the called party picks up the phone  31 . That is, it is judged if the called party answers the phone. When YES, that is, the called party answers the phone  31 , the routine proceeds to step S 9 , where it is judged if the message sent was run to the end. Based on the results of judgement, the “listened-to-end” flag and ending time in the phone usage log file  25  are updated (set) and the routine ended. On the other hand, when NO, that is, when the called party does not answer the phone, the routine proceeds to step S 8 . 
     At step S 8 , the time is monitored. For example, the time is monitored for up to 120 seconds. If below 120 seconds, the routine returns to the judgement of step S 7 , while when over 120 seconds, it proceeds to step S 11 . 
     At step S 10 , the time is monitored. When over 120 seconds, it proceeds to step S 11 . 
     At step S 11 , the routine proceeds to the answering service number announcement processing of  FIGS. 3A  to  3 D. 
       FIG. 2C  shows an example of the detailed processing for reading and broadcasting (sending) the message of step S 6  in FIG.  2 A. 
     In  FIG. 2C , at step S 21 , the CM master  21  is searched through using the CM number in the customer CM master  22 . This is done by extracting the CM number (commercial number, for example, “001”) registered linked with the phone number of the caller (customer number) from the customer CM master  22  of FIG.  8 B and searching for the record of the CM number (“001”) from the CM master  21  of FIG.  8 A. 
     At step S 22 , the content file is selected based on the CM switching code. This is done by switching and selecting among a plurality of recorded content files (selecting a content file corresponding to the CM switching code) based on the CM switching code (for example, “1” meaning change every Monday) of the record of the CM number (for example, “001”) in the CM master  21  of FIG.  8 A. 
     Step S 25  to step S 30  of  FIG. 2D  show the detailed processing of step S 22  of FIG.  2 C. 
     At step S 25 , the CM switching code in the CM master  21  for the CM number is referred to. 
     At step S 26 , it is judged if the content is determined by day. This is done by judging if the CM switching code referred to at step S 25  calls for changing the content by day. When YES, the routine proceeds to step S 27 , where the file path in the CM master  21  for that day is obtained, then the routine proceeds to step S 23 . On the other hand, when NO at step S 26 , the routine proceeds to step S 28 . 
     At step S 28 , it is judged if the content is determined by hour. This is done by judging if the CM switching code referred to at step S 25  calls for changing the content by hour. When YES, the routine proceeds to step S 29 , where the file path in the CM master  21  for that hour is obtained, then the routine proceeds to step S 23 . On the other hand, when NO at step S 28 , the routine proceeds to step S 30 , where the file path of the default file name in the CM master  21  is obtained, then the routine proceeds to step S 23 . 
     At step S 23 , the content file of the file path designated at step S 27 , step S 29 , or step S 30  is loaded. 
     At step S 24 , the hard disk storage device is accessed and the content of the file is reproduced (sent toward the telephone  1  of the customer). Next, the content is played to the calling customer. 
       FIG. 3  is a view of the overall layout of  FIGS. 3A  to  3 D.  FIGS. 3A  to  3 D are flow charts of the answering service announcement processing of the present invention.  FIGS. 3A and 3B  are overall flow charts. 
     In  FIGS. 3A and 3B , at step S 31 , the called telephone number is searched for from the telephone numbers registered in the customer CM master  22 . 
     At step S 32 , it is judged if the customer number is registered. If YES, that is, it is judged that the customer number is registered, the routine proceeds to step S 33 . If NO at step S 32 , that is, it is learned that the customer number is not registered and therefore the called customer has not registered that it wishes cash back in return for transmitting a message (content), the routine proceeds to step S 37 , where the default normal message is broadcast, then the routine proceeds to step S 36 , where the answering service recording function is activated and the routine ends. 
     At step S 33 , it is learned that the called customer has registered that it wishes cash back in return for transmitting a message (content), so a new phone usage log file  25  is recorded with the “customer number” and “CM number” obtained by referring to the customer CM master  22  and is recorded with the telephone number of the caller, that is, the “other party number”, and the starting time for reproducing the message. Logs of these are stored. 
     At step S 34 , the registered message of the called customer is read and reproduced. This is done by reading the registered message (content, commercial, etc.) of the CM number registered linked with the CM customer master  22  of  FIG. 8B , broadcasting (sending) it toward the phone  1  of the calling customer, and playing it to the calling customer. At step S 35 , the “listened-to-end” flag in the phone usage log file  25  is updated (set) to YES (listened to end), then the routine proceeds to step S 36 , where the routine proceeds to the answering service recording function and the routine ends. Further, while not shown, when the calling customer hangs up the phone during the answering service announcement message, the “listened-to-end” flag is updated to NO (hung up in the middle) and the routine is ended as it is. 
       FIG. 3C  shows an example of the detailed processing for reading and broadcasting (sending) a message of step S 34  in  FIGS. 3A and 3B . Here, step S 41  to step S 50  of  FIGS. 3C and 3D  correspond to step S 21  to step S 30  of  FIGS. 2C and 2D , so explanations thereof will be omitted. 
     By the above step S 41  to step S 50 , the calling customer dials the phone  1 , the called party answers the phone, then a predetermined file is loaded in accordance with a switching code based on the customer CM master  22  of FIG.  8 B and the CM master  21  of  FIG. 8A , then the content is converted to audio and sent toward the phone  1  of the customer. At this time, by setting the switching code (setting it to change the content for each day, for each hour, for each season, etc.), it is possible to switch the content sent to the phone  1  of the calling customer to the optimal content at any time. 
       FIG. 4  is a view of the overall layout of  FIGS. 4A  to  4 D.  FIGS. 4A  to  4 D are flow charts of the processing for selection and registration of a message set in advance by a called customer according to the present invention. 
       FIGS. 4A and 4B  show an example of an operator of a service center handling processing for registration for a customer by phone. 
     In  FIGS. 4A and 4B , at step S 51 , the operator answers a call from a customer. 
     At step S 52 , it confirms (authenticates) the customer. 
     At step S 53 , it compares the registered telephone number with the customer number to obtain the CM number. 
     At step S 54 , it explains and previews the CM information (explained in detail at step S 71  to step S 76  of FIGS.  4 C and  4 D). 
     At step S 55 , it judges if the CM has been decided on. When YES, the routine proceeds to step S 56 , where the operator performs processing linking the customer and the CM, then the routine ends. 
     Due to the above, it becomes possible to perform processing for linking the customer information and the stock information (CM&#39;s and contents). 
       FIG. 4B  shows an example of input by a customer by the Web or i-mode. 
     In  FIG. 4B , at step S 61 , customer authentication processing (ID, password) is performed. Next, the routine proceeds to step S 52 , where processing similar to the above is performed. 
       FIGS. 4C and 4D  show an example of processing for explaining and previewing CM information. 
     In  FIGS. 4C and 4D , at step S 71 , the CM master  21  is searched through by the CM number in the customer CM master  22 . For example, the CM master  21  is searched through as shown in FIG.  4 D. When the result at step S 71  is “EXISTS”, the routine proceeds to step S 72 , while when the result is “NOT EXIST”, the routine proceeds to step S 74 . 
     At step S 72 , since it is learned by the “EXISTS” at step S 71  that the CM exists in the CM master  21  of  FIG. 8A , it is then judged whether to change the CM/rate. When YES, the routine proceeds to step S 74 , while when NO, the CM is previewed at step S 73  and the routine ended. 
     At step S 74 , the CM name, CM number, and CM content are displayed from the CM master  21  and the desired CM is selected. In this case, when an operator receives this by a phone call, the operator verbally explains the information regarding the CM to the customer to persuade the customer to select it. 
     At step S 75 , the customer previews the CM. 
     At step S 76 , the amount is shown from the cashback master  23  using the CM number as a key and the rate system is determined. For example, as shown by the cashback master  23  described in  FIG. 4D , either a flat rate or usage-based rate system is determined. 
       FIG. 5  is a view of the overall layout of  FIGS. 5A and 5B . 
       FIGS. 5A and 5B  are flow charts of the processing for a content preparer (agent) of the present invention to register various conditions relating to the content stock and cashback service. 
     In  FIG. 5A , at step S 81 , the preparer performs processing for physically and temporarily storing the content. For example, it copies data by file transfer technology on the Internet or on a CD-ROM, MO, FDD, tape, or other medium. 
     At step S 82 , the CM agent company registers the information relating to a CM in the CM master  21 . For example, it registers it as shown in the CM master  21  shown in FIG.  5 B. 
     At step S 83 , the CM agent company or managing company (intermediary) register its information in the CM agent master  24 . For example, it registers this in the CM agent master  24  shown in FIG.  5 B. 
     At step S 84 , the CM agent company registers information in the CM cashback master  23 . For example, it registers this in the CM cashback master  23  shown in FIG.  5 B. 
     Due to the above, it becomes possible to perform processing for registration of the CM stock and the cashback amount. 
       FIG. 6  is a view of the overall layout of  FIGS. 6A and 6B .  FIGS. 6A and 6B  are flow charts of the processing when cash is returned to the calling customer of the present invention. 
     In  FIG. 6A , at step S 91 , it is judged if the “listened-to-end” flag is YES using as a key the other party number in the phone usage log file  25 . When YES, that is, it is learned that the CM was listened to up to the end, the routine proceeds to step  92 , where the amount of the usage-based rate in the CM cashback master  23  is returned to the caller using the CM number as a key (that amount is added to the cashback amount to update it as shown in the caller log file  26  of FIG.  6 A). On the other hand, when NO at step S 91 , it is learned that the phone was hung up in the middle of the CM, so at step S 93  (FIG.  6 B), the amount of the usage-based rate in the CM cashback master  23 ×caller rate is returned to the caller using the CM number as a key (similarly updated as in the caller log file  26  of FIG.  6 A). When the CM number is “001” (FIG.  8 C), reference to the CM cashback master  23  shows that the caller discount rate is “100%”, so the amount becomes 50 yen regardless of whether the entire CM was listened to or not. 
       FIG. 7  is a view of the overall layout of  FIGS. 7A  to  7 D.  FIGS. 7A  to  7 D are flow charts of the billing processing of the present invention. 
       FIGS. 7A and 7B  show an example of processing for billing a customer. 
     In  FIGS. 7A and 7B , at step S 101 , preparation of statement data including the discount to the customer starts based on the phone usage log file  25  and the customer CM master  22 . 
     At step S 102 , it is judged if the phone usage log file  25  includes the customer number registered in the customer Cm master  22 . When YES, the routine proceeds to step S 103 . When NO, the routine ends and processing for billing normal charges is performed. 
     At step S 103  (FIG.  7 B), it is determined if the rate is a flat one from the customer CM master  22 . That is, it is determined if the rate system of the entry concerned is a flat rate from the customer CM master  22  of FIG.  7 A. When YES, the routine proceeds to step S 104 , where the flat rate in the CM cashback master  23  is made the cashback amount in the customer CM master  22 , then the routine proceeds to step S 108 . On the other hand, when NO at step S 103 , a usage-based system is used for the cashback service, so the routine proceeds to step S 105  (FIG.  7 B). 
     At step S 105  (FIG.  7 B), it is determined if the “listened-to-end” flag in the phone usage log file  25  containing that customer number is YES (listened to the end). When YES, the routine proceeds to step S 106 , where the usage-based rate in the CM cashback master  23  is added to the cashback amount in the customer CM master  22 , then the routine proceeds to step S 108 . When NO at step S 105 , that is, it is learned that the “listened-to-end” flag is NO and the phone was hung up in the middle of the CM, the routine proceeds to step S 107 , where no cash is returned. Therefore, nothing is added to the cashback amount in the customer CM master  22  and the routine proceeds to step S 108 . When there is another phone usage log file  25  containing that customer number, the routine returns to step S 102 , where the processing is repeated. 
     At step S 108 , the total of the cashback amount in the customer CM master  22  is found for each customer No. 
     At step S 109 , the bill is prepared by subtracting the total cashback amount from the phone charges. 
       FIGS. 8A  to  8 F show examples of masters and files of the present invention. The “processing  1 ” to “processing  12 ” shown in the figures are processings registered or updated in the “processing  1 ” to “processing  12 ” shown in anyone of  FIGS. 2A  to  2 D to  FIGS. 7A  to  7 D. 
       FIG. 8A  shows an example of the CM master  21 . The CM master  21  is registered with the following information linked together:

     Here, the “CM number” is the number of the commercial and corresponds to the number of the commercial to be played to the customer registered in advance linked with the customer number of the customer CM master  22  shown in the later explained FIG.  8 B. The “Type” is set as “Ringer”, that is, the type of sending a commercial to a calling customer instead of the audible ringing signal of the telephone, or with “Answering service”, that is, type of answering the call and sending a commercial to a calling customer instead of the conventional answering service message. The “CM name” is the name of the commercial determined by the CM number. The “CM content” is the content of the commercial determined by the CM number. The “Number of seconds” is the number of seconds during which the commercial is sent to the customer. The “Message” is the message announcing the commercial. The “CM switching code” is the code for switching the commercial, for example, “1” meaning to change it every Monday. The “File name when CM switching code is 1”, “File name when CM switching code is 2”, and “Default file” are the names of the files storing the commercials when the switching code is “1”, “2”, and default. 
     In this way, by registering information in the CM master  21  (the registration of all information is performed by the CM agent companies by the “processing  6 ”), when a calling customer (telephone number) is learned from the customer CM master  22 , it is possible to generate audio based on the corresponding CM file from the CM master  21  based on the corresponding CM number and send it to the calling customer for listening or to make the customer listen to another commercial switched on for example Monday in accordance with the switching code. 
       FIG. 8B  shows an example of the customer CM master  22 . The customer CM master  22  is registered with the following information linked together:

The “Usage-based rate (amount per call)” is the rate per call when the cashback amount for a CM number is based on usage. The “Caller discount rate” is the caller rate used for example at step S 93  of  FIG. 6B  explained above, that is, the coefficient used for multiplication with the usage-based rate when calculating the amount of cash to be returned when the “listened-to-end” flag is NO (phone is hung up in the middle of the commercial). The “CM agent number” is the number of the commercial agent. 
     The CM cashback master  23  is registered with the rate for each CM number, divided into flat rates and usage-based rates, by the CM agent companies by the “processing  8 ” and registered with the discount rate for the cashback service of the caller side.
