On the company&#39;s mobile communication network  2  are installed a calling-side exchange  21  and a receiving-side exchange  22 . Further, the mobile communication center  3  is installed with a server apparatus  31 . In addition, to simplify descriptions,  FIG. 1  shows the case of a single calling-side terminal apparatus  1 A, a single receiving-side terminal apparatus  1 B and a single another-company terminal apparatus  5 , but the present invention is actually applicable to pluralities of calling-side terminal apparatuses, receiving-side terminal apparatuses and another-company terminal apparatuses. 
     Each of the terminal apparatuses  1 A,  1 B and  5  is a mobile terminal apparatus, and has an operating system (mobile apparatus OS), and on the mobile apparatus OS operate the browser function, viewer function and other functions. Further, the mobile communication network  2  is a network among the terminal apparatuses  1 A,  1 B that are the company&#39;s mobile terminals, and the mobile communication center  3 , and the mobile communication network  4  is a network between the another company&#39;s mobile terminal  5  and the mobile communication center  3 . The mobile communication network  2  includes a mobile packet communication network, in addition to the normal mobile communication network. Further, the mobile communication center  3  has, for example, an i-mode (registered trademark) server and the like, has the gateway function for connecting the mobile communication networks  2  and  4 , and more specifically, has the information distribution function, e-mail transmission/reception function, e-mail storage function, contracted client management function, information provider management function and information fee billing function. 
       FIG. 2  is a diagram illustrating a configuration of each of the terminal apparatuses  1 A,  1 B in the information updating system as shown in  FIG. 1 . In addition, the terminal apparatuses  1 A,  1 B are assumed to have all the components provided in the normal mobile terminal apparatus. Each of the terminal apparatuses  1 A,  1 B is mainly comprised of a control section  11  that controls the entire apparatus, a communication control section  12  that communicates with terminal apparatuses and mobile communication center  3 , an input section  13  to input various data, a display section  14  that displays various information, a storing section  15  that stores various data including an address book containing registered information as shown in  FIG. 6 , a search section  16  that searches the address book for registered information of a predetermined user, and an updating section  17  that updates the registered information of the user based on the updated information. 
     The communication control section  12  has the wireless communication function supporting the cellular telephone function, and performs wireless communication for calls and data communication with receiving-side another terminal apparatus  1 B of a registered user of the company via the calling-side exchange  21  and the company&#39;s mobile communication network  2 . Further, the communication control section  12  performs wireless communication with the calling-side exchange  21 , the company&#39;s mobile communication network  2  and the mobile communication center  3  to transmit updated information. 
     As shown in  FIG. 6 , the address book stored in the storing section  15  contains at least a telephone number and e-mail address  6   a  of a communicating party, terminal function information  6   b,  personal information  6   c  such as an address and the like, field  6   d  for comments, etc. 
     The search section  16  searches the address book stored in the storing section  15  for a user (information of the calling-side terminal apparatus) based on address information (for example, a telephone number or e-mail address) about the user included in the received updated information. In this case, when at least one of the telephone number and e-mail address is registered with the address book, it is possible to search for the user. In this case, when both of the telephone number and e-mail address are registered with the address book, the search is made preferentially based on the telephone number. For example, in the case that the updated information of D-san from the calling-side terminal apparatus is as shown in  FIG. 8(   a ), when the telephone number and e-mail address are registered for D-san as shown in  FIG. 8(   b ), the address book is searched using the telephone number as a key. Meanwhile, when the e-mail address is only registered for D-san, the address book is searched using the e-mail address as a key. 
     The updating section  17  changes the registered information in the address book stored in the storing section  15  by operation from the input section  13 . In other words, the updating section  17  in the calling-side terminal apparatus  1 A generates updated information based on a change of the registered information. Meanwhile, the updating section  17  of the receiving-side terminal apparatus  1 B updates the registered information in the address book based on the received updated information. 
       FIG. 3  is a block diagram illustrating a configuration of the calling-side exchange in the information updating system as shown in  FIG. 1 . In addition, the calling-side exchange  21  is assumed to have all the components provided in the normal exchange. The calling-side exchange  21  is mainly comprised of a control section  211  that controls the entire apparatus, a communication control section  212  that communicates with the calling-side terminal apparatus  1 A, receiving-side exchange  22  or server apparatus  31 , a checking section  213  that acquires a telephone number associated with an e-mail address, and a determining section  214  that determines whether or not the receiving-side terminal apparatus  1 B is a registered user of the company. 
     When the updated information is transmitted to an e-mail address of the receiving-side terminal apparatus  1 B from the calling-side terminal apparatus  1 A, the checking section  213  gains access to the server apparatus  31  of the mobile communication center  3  that manages e-mail addresses via the communication control section  212 , and checks a telephone number associated with the e-mail address to acquire. The acquired telephone number is sent to the determining section  214 . 
     The determining section  214  determines whether or not the receiving-side terminal apparatus  1 B is a registered user of the company based on the address information of the receiving-side terminal apparatus  1 B transmitted from the calling-side terminal apparatus  1 A. The calling-side exchange  21  has information of telephone numbers of registered users of the company, checks the telephone number of the receiving-side terminal apparatus  1 B against the information of telephone numbers of registered users of the company, and thereby determines whether or not the receiving-side terminal apparatus  1 B is a registered user of the company. The determination result is sent to the control section  211 . The control section  211  transmits the updated information from the calling-side terminal apparatus  1 A to the receiving-side exchange  22  when the determination result indicates the registered user of the company, while transmitting the updated information from the calling-side terminal apparatus  1 A to the server apparatus  31  when the determination result does not indicate the registered user of the company. 
       FIG. 4  is a diagram illustrating a configuration of the receiving-side exchange in the information updating system as shown in  FIG. 1 . In addition, the receiving-side exchange  22  is assumed to have all the components provided in the normal exchange. The receiving-side exchange  22  is mainly comprised of a control section  221  that controls the entire apparatus, a communication control section  222  that communicates with the receiving-side terminal apparatus  1 B, calling-side exchange  22  or server apparatus  31 , and a determining section  223  that determines whether or not the receiving-side terminal apparatus  1 B supports this system. 
     The determining section  223  determines whether or not the receiving-side terminal apparatus  1 B is capable of supporting the system based on the address information of the receiving-side terminal apparatus  1 B transmitted from the calling-side terminal apparatus  1 A. The receiving-side exchange  22  has information of telephone numbers of terminal apparatuses capable of supporting the system, checks the telephone number of the receiving-side terminal apparatus  1 B against the information of telephone numbers of terminal apparatuses capable of supporting the system, and thereby determines whether or not the receiving-side terminal apparatus  1 B is capable of supporting the system. The determination result is sent to the control section  221 . The control section  221  transmits the updated information from the calling-side terminal apparatus  1 A to the receiving-side terminal apparatus  1 B when the determination result indicates that the apparatus  1 B supports the system, while transmitting the updated information from the calling-side terminal apparatus  1 A to the server apparatus  31  when the determination result indicates that the apparatus  1 B does not support the system. 
       FIG. 5  is a diagram illustrating a configuration of the server apparatus in the information updating system as shown in  FIG. 1 .

     The managing section  313  manages the address information of mobile terminal apparatuses. For example, when the apparatus  31  is entrusted with address books of the users, the section  313  manages the address books. 
     Based on the updated information from the calling-side terminal apparatus  1 A, the updating section  314  updates the registered information of the address book managed in the managing section  313 . Meanwhile, the updating section  314  generates an update site based on the updated information from the calling-side terminal apparatus  1 A. 
     The extracting section  315  extracts transmission destinations having the address information of the calling-side terminal apparatus. The extracting section  315  extracts receiving-side terminal apparatuses  1 B to transmit the updated information from the calling-side terminal apparatus  1 A from the address books managed in the managing section  313 . More specifically, the section  315  extracts address books containing the address information of the calling-side terminal apparatus from the address books managed in the managing section  313 , and specifies terminal apparatuses of users of the extracted address books. In other words, the section  315  specifies address information of the terminal apparatuses to transmit the updated information as the transmission destinations. 
     Described next is an information updating method according to Embodiment 1 of the invention. 
     In the information updating system of this Embodiment, in transmission after updating the address information such as the telephone number, e-mail address and the like, when the calling-side terminal apparatus  1 A transmits updated information generated from the updated address information to the calling-side exchange  21  in addition to the transmission information, the updated information is transmitted to the receiving-side terminal apparatus  1 B via the calling-side exchange  21  and receiving-side exchange  22 . 
     In other words, in the information updating method of the invention, the updated information and the address information of the mobile terminal apparatus is transmitted from the calling-side terminal apparatus to the receiving-side terminal apparatus, and the receiving-side terminal apparatus searches the address book for the information of the calling-side terminal apparatus based on the address information, and updates the searched information of the calling-side terminal apparatus based on the updated information. 
       FIG. 7  is a sequence diagram to explain the information updating method according to Embodiment 1 of the invention. This sequence is in the case where a user of the receiving-side terminal apparatus is a registered user of the company, and the receiving-side terminal apparatus is capable of supporting this system. Described herein is the case where the calling-side terminal apparatus  1 A first updates the address information, and then, calls the receiving-side terminal apparatus  1 B. In addition, the invention is not limited to this aspect, and the calling-side terminal apparatus  1 A may transmit the updated information to the receiving-side terminal apparatus  1 B separately from a call. 
     When the calling-side terminal apparatus  1 A transmits the updated information obtained by updating the address information, the updated information is transmitted to the calling-side exchange  21  (ST 11 ). In the calling-side exchange  21 , the determining section  214  determines whether or not the receiving-side terminal apparatus  1 B is a registered user of the company from the address information of the receiving-side terminal apparatus  1 B (ST 12 ). Then, when the receiving-side terminal apparatus  1 B is a registered user of the company, the updated information is transmitted to the receiving-side exchange  22  (ST 13 ). In addition, in the case that the calling-side terminal apparatus  1 A transmits the updated information, when the updated information is transmitted to the e-mail address of the receiving-side terminal apparatus  1 B, in the calling-side exchange  21 , the checking section  213  gains access to the server apparatus  31  of the mobile communication center  3  to acquire a telephone number corresponding to the e-mail address, and the updated information is transmitted to the receiving-side exchange  22  with the telephone number. 
     In the receiving-side exchange  22 , the determining section  223  determines whether or not the receiving-side terminal apparatus  1 B is capable of supporting this system from the address information of the receiving-side terminal apparatus  1 B (ST 14 ). Then, when the receiving-side terminal apparatus  1 B is capable of supporting the system, the exchange  22  transmits the updated information to the receiving-side terminal apparatus  1 B (ST 15 ). Next, in the receiving-side terminal apparatus  1 B, the search section  16  searches the address book based on the address information of the calling-side terminal apparatus  1 A, and the searched registered information is updated based on the updated information (ST 16 ). Then, the receiving-side terminal apparatus  1 B transmits a result indicating that update was made to the calling-side terminal apparatus  1 A (ST 17 ), and in the calling-side terminal apparatus  1 A, the display section  14  displays the update result transmitted from the receiving-side terminal apparatus  1 B (ST 18 ). By this means, the user of the calling-side terminal apparatus  1 A is capable of confirming completion of update of the registered information in the address book of the communicating party. 
     When the receiving-side terminal apparatus  1 B receives the updated information, for example, as shown in  FIG. 9(   a ), the display section  14  displays an update mark. When the user clicks the update mark, a screen as shown in  FIG. 9(   b ) is displayed to require a reply to permission of update. At this point, as shown in  FIG. 9(   c ), the user is capable of checking the update content. Then, when the user permits update, as shown in  FIG. 9(   d ) or  9 ( e ), the registered information of the address book is updated based on the updated information, and display of “new” indicating the information being updated is also displayed. In addition, the display examples and procedure as shown in  FIG. 9  are examples, and capable of being modified as appropriate. 
     Thus, when the user of the receiving-side terminal apparatus is a registered user of the company and the receiving-side terminal apparatus is capable of supporting the system, it is possible to automatically update the registered information in the address book of the communicating party individually. By this means, the user updating the registered information is capable of readily notifying the communicating party of the updated information, and it is possible on the communicating party side to update the registered information without conducting work for editing the address book. 
       FIG. 10  is another sequence diagram to explain the information updating method according to Embodiment 1 of the invention. This sequence is in the case where a user of the receiving-side terminal apparatus is a registered user of the company, and the receiving-side terminal apparatus is not capable of supporting this system. Described herein is the case where the calling-side terminal apparatus  1 A first updates the address information, and then, calls the receiving-side terminal apparatus  1 B. In addition, the invention is not limited to this aspect, and the calling-side terminal apparatus  1 A may transmit the updated information to the receiving-side terminal apparatus  1 B separately from a call. 
     When the calling-side terminal apparatus  1 A transmits the updated information obtained by updating the address information, the updated information is transmitted to the calling-side exchange  21  (ST 21 ). In the calling-side exchange  21 , the determining section  214  determines whether or not the receiving-side terminal apparatus  1 B is a registered user of the company from the address information of the receiving-side terminal apparatus  1 B (ST 22 ). Then, when the receiving-side terminal apparatus  1 B is a registered user of the company, the updated information is transmitted to the receiving-side exchange  22  (ST 23 ). In addition, in the case that the calling-side terminal apparatus  1 A transmits the updated information, when the updated information is transmitted to the e-mail address of the receiving-side terminal apparatus  1 B, in the calling-side exchange  21 , the checking section  213  gains access to the server apparatus  31  of the mobile communication center  3  to acquire a telephone number corresponding to the e-mail address, and the updated information is transmitted to the receiving-side exchange  22  with the telephone number. 
     In the receiving-side exchange  22 , the determining section  223  determines whether or not the receiving-side terminal apparatus  1 B is capable of supporting this system from the address information of the receiving-side terminal apparatus  1 B (ST 24 ). Then, when the receiving-side terminal apparatus  1 B is not capable of supporting the system, the exchange  22  transmits the updated information to the server apparatus  31  of the mobile communication center  3  (ST 25 ). 
     In the server apparatus  31 , the updating section  314  generates an update site including the updated information from the receiving-side exchange  22  (ST 26 ). Then, the communication control section  312  transmits an address (URL) of a storage location of the generated update site to the receiving-side exchange  22  (ST 27 ). In addition, the update site to generate is not limited particularly in the structure or the like, as long as the updated information is included in the site. 
     Next, in the receiving-side exchange  22 , the communication control section  221  transmits the URL of the update site to the telephone number of the receiving-side terminal apparatus  1 B by SMS (Short Message Service) (ST 28 ). In the receiving-side terminal apparatus  1 B, the communication control section  12  gains access to the URL of the update site (ST 29 ), and displays the update site in the display section  14  of the receiving-side terminal apparatus  1 B. By this means, the user of the receiving-side terminal apparatus  1 B is capable of recognizing update of the registered information in the calling-side terminal apparatus  1 A by the update site. Further, when necessary, the user downloads the updated information or registered information including the updated information from the server apparatus  31  (ST 30 ). By this means, it is possible to reflect update of the registered information in the calling-side terminal apparatus  1 A in the receiving-side terminal apparatus  1 B. In this case, the search section  16  searches the address book based on the address information of the calling-side terminal apparatus  1 A, and the searched registered information is updated based on the updated information. 
     When the receiving-side terminal apparatus  1 B receives the SMS, for example, as shown in  FIG. 12(   a ), the display section  14  displays an SMS mark. When the user clicks the SMS mark, the URL of the update site is displayed on the screen as shown in  FIG. 12(   b ). Then, when the user clicks the URL of the update site, the user is capable of viewing the updated information of the registered information of the address book as shown in  FIG. 12(   c ). In addition, the display examples and procedure as shown in  FIG. 12  are examples, and capable of being modified as appropriate. 
     Then, the server apparatus  31  transmits a result indicating the updated information being checked to the calling-side terminal apparatus  1 A (ST 31 ), and the calling-side terminal apparatus  1 A displays the check result transmitted from the server apparatus  31  in the display section  14  (ST 32 ). By this means, the user of the calling-side terminal apparatus  1 A is capable of recognizing that the communicating party checked update of the registered information of the address book. 
     Thus, even when the user of the receiving-side terminal apparatus is a registered user of the company but the receiving-side terminal apparatus is not capable of supporting the system, it is also possible to notify the communication party of update of the registered information of the address book individually. 
       FIG. 11  is still another sequence diagram to explain the information updating method according to Embodiment 1 of the invention. This sequence diagram is in the case that a user of the receiving-side terminal apparatus is not a registered user of the company. Described herein is the case where the calling-side terminal apparatus  1 A first updates the address information, and then, calls the receiving-side terminal apparatus  5 . In addition, the invention is not limited to this aspect, and the calling-side terminal apparatus  1 A may transmit the updated information to the receiving-side terminal apparatus  5  separately from a call. 
     When the calling-side terminal apparatus  1 A transmits the updated information obtained by updating the address information, the updated information is transmitted to the calling-side exchange  21  (ST 41 ). In the calling-side exchange  21 , the determining section  214  determines whether or not the receiving-side terminal apparatus  5  is a registered user of the company from the address information of the receiving-side terminal apparatus  5  (ST 42 ). Then, when the receiving-side terminal apparatus  5  is not a registered user of the company, the updated information is transmitted to the server apparatus  31  of the mobile communication center  3  (ST 43 ). 
     In the server apparatus  31 , the updating section  314  generates an update site including the updated information from the calling-side exchange  21  (ST 44 ). Then, the communication control section  312  transmits an address (URL) of a storage location of the generated update site to the calling-side exchange  21  (ST 45 ). In addition, the update site to generate is not limited particularly in the structure or the like, as long as the updated information is included in the site. 
     Next, in the calling-side exchange  21 , the communication control section  221  transmits the URL of the update site to the telephone number of the receiving-side terminal apparatus  5  by e-mail via the mobile communication center  3  and another-company mobile communication network  4  (ST 46 ). Next, the receiving-side terminal apparatus  5  gains access to the URL of the update site (ST 47 ) to display the update site. By this means, the user of the receiving-side terminal apparatus  5  is capable of recognizing update of the registered information in the calling-side terminal apparatus  1 A by the update site. 
     When the receiving-side terminal apparatus  5  receives the e-mail, for example, as shown in  FIG. 12(   a ), an SMS mark is displayed on the display screen. When the user clicks the SMS mark, the URL of the update site is displayed on the screen as shown in  FIG. 12(   b ). Then, when the user clicks the URL of the update site, the user is capable of viewing the updated information of the registered information of the address book as shown in  FIG. 12(   c ). In addition, the display examples and procedure as shown in  FIG. 12  are examples, and capable of being modified as appropriate. 
     Then, the server apparatus  31  transmits a result indicating the updated information being checked to the calling-side terminal apparatus  1 A (ST 48 ), and the calling-side terminal apparatus  1 A displays the check result transmitted from the server apparatus  31  in the display section  14  (ST 49 ). By this means, the user of the calling-side terminal apparatus  1 A is capable of recognizing that the communicating party checked update of the registered information of the address book. 
     Thus, even when the user of the receiving-side terminal apparatus is not a registered user of the company, it is also possible to notify the communication party of update of the registered information of the address book individually. In addition, in first access to the update site of the server apparatus  31 , authentication may be performed to verify the access from the receiving-side terminal apparatus  5  that is the communicating party of the calling-side terminal apparatus  1 A. 
     When authentication processing is performed, for example, the processing is executed in the procedure as shown in  FIG. 13 . When the calling-side exchange  21  transmits the updated information to the server apparatus  31 , the exchange  21  also transmits the address information of the receiving-side terminal apparatus  5  (ST 43 ). When the server apparatus  31  receives the updated information and address information, the apparatus  31  transmits authentication information (for example, authentication code) to the calling-side exchange  21  (ST 61 ). At this point, the server apparatus  31  holds the address information (e-mail address) and authentication information of the receiving-side terminal apparatus  5 . When the calling-side exchange  21  receives the authentication information, the exchange  21  transmits the authentication information to the e-mail address of the receiving-side terminal apparatus  5  by e-mail (ST 62 ). Then, when the receiving-side terminal apparatus  5  receives the e-mail, the apparatus  5  transmits an e-mail (authentication e-mail) including the authentication information to the server apparatus  31  (ST 63 ). 
     The server apparatus  31  compares the held e-mail address and authentication information with the e-mail address of the sender of the authentication e-mail and the authentication information, and authenticates the user of the receiving-side terminal apparatus  5  (ST 64 ). When the user is authenticated, the URL of the update site is transmitted to the receiving-side terminal apparatus  5  by e-mail (ST 65 ). Then, the receiving-side terminal apparatus  5  gains access to the URL of the update site (ST 66 ) to display the update site. At this point, the server apparatus  31  acquires specific information such as a user ID, telephone number or the like, and another specific information (identification information) such as a client certificate or the like on the receiving-side terminal apparatus  5 . By this means, the user of the receiving-side terminal apparatus  5  is capable of checking update of the registered information in the calling-side terminal apparatus  1 A using the update site. Then, the server apparatus  31  transmits a result indicating the updated information being checked to the receiving-side terminal apparatus  5  (ST 67 ). With respect to subsequent accesses to the server apparatus  31  from the receiving-side terminal apparatus  5 , the server apparatus  31  is able to perform authentication using the acquired identification information, and the need of the above-mentioned authentication processing is eliminated. 
     Embodiment 2 
     In this Embodiment, the case is described where updated information of the calling-side terminal apparatus is collectively distributed to receiving-side terminal apparatuses, and the receiving-side terminal apparatus updates registered information of the calling-side terminal apparatus based on the updated information. 
     In the information updating method of the invention, the calling-side terminal apparatus transmits the updated information of mobile terminal information to the server apparatus, the server apparatus extracts receiving-side terminal apparatuses having the address information of the calling-side terminal apparatus from management information of mobile terminal apparatuses, and distributes the updated information to the extracted receiving-side terminal apparatuses, and the receiving-side terminal apparatuses update the information of the calling-side terminal apparatus based on the updated information. 
       FIG. 14  is a sequence diagram to explain an information updating method according to Embodiment 2 of the invention. The sequence as shown in  FIG. 14(   a ) is in the case where users of the receiving-side terminal apparatuses are registered users of the company, and the receiving-side terminal apparatuses are capable of supporting this system. The condition is assumed herein that the server apparatus  31  manages address books of mobile terminal apparatuses. 
     When the calling-side terminal apparatus  1 A transmits the updated information obtained by updating the address information, the updated information is transmitted to the server apparatus  31  of the mobile communication center  3  (ST 51 ). In the server apparatus  31 , the extracting section  315  extracts address books including the registered information (address information) of the calling-side terminal apparatus  1 A from among the address books managed in the managing section  313  (ST 52 ). Then, the apparatus  31  distributes the updated information of the calling-side terminal apparatus  1 A collectively to telephone numbers of users of the extracted address books (ST 53 ). In other words, the apparatus  31  broadcasts the updated information simultaneously to terminal apparatuses (receiving-side terminal apparatuses  1 B) of owners of the address books including the registered information of the user of the calling-side terminal apparatus  1 A. 
     Next, in the receiving-side terminal apparatus  1 B, the search section  16  searches the address book based on the address information of the calling-side terminal apparatus  1 A, and the searched registered information is updated based on the updated information (ST 54 ). Then, the receiving-side terminal apparatus  1 B transmits a result indicating update being made to the calling-side terminal apparatus  1 A (ST 55 ), and in the calling-side terminal apparatus  1 A, the display section  14  displays the update result transmitted from the receiving-side terminal apparatus  1 B (ST 56 ). By this means, the user of the calling-side terminal apparatus  1 A is capable of confirming completion of update of the registered information in the address book of the communicating party. 
     Thus, when the users of the receiving-side terminal apparatuses are registered users of the company and the receiving-side terminal apparatuses are capable of supporting the system, it is possible to automatically update the registered information in the address books of the communicating parties by one operation. By this means, the user updating the registered information is capable of collectively notifying a plurality of communicating parties of the updated information, and it is possible on each communicating party side to update the registered information without conducting work for editing the address book. 
     Also in this Embodiment, as in Embodiment 1, cases are considered that the receiving-side terminal apparatus  1 B is not capable of supporting the system, and that the receiving-side terminal apparatus  5  is not a registered user of the company. In such cases, as in Embodiment 1, the calling-side exchange  21  and receiving-side exchange  22  make determinations, i.e. the calling-side exchange  21  determines whether or not the user is a registered user of the company, while the receiving-side exchange  22  determines whether or not the apparatus is capable of supporting the system, and the apparatus gains access to the update site generated in the server apparatus  31 . 
     In this case, as shown in  FIG. 14(   b ), when the server apparatus  31  receives the updated information, the apparatus  31  generates an update site including the updated information, and transmits an address (URL) of a storage location of the generated update site to the receiving-side terminal apparatuses  1 B,  5  (ST 57 ). The receiving-side terminal apparatuses  1 B,  5  gain access to the URL of the update site (ST 58 ), and display the update site. By this means, the users of the receiving-side terminal apparatuses  1 B,  5  are capable of recognizing update of the registered information in the calling-side terminal apparatus  1 A by the update site. Further, when the user of the receiving-side terminal apparatus  1 B is a registered user of the company, as needed, the user downloads the updated information or registered information including the updated information from the server apparatus  31  (ST 59 ). By this means, it is possible to reflect update of the registered information in the calling-side terminal apparatus  1 A in the receiving-side terminal apparatus  1 B. In this case, the search section  16  searches the address book based on the address information of the calling-side terminal apparatus  1 A, and the searched registered information is updated based on the updated information. 
     Then, the receiving-side terminal apparatuses  1 B,  5  transmit a result indicating the updated information being checked to the calling-side terminal apparatus  1 A (ST 55 ), and the calling-side terminal apparatus  1 A displays the check result (ST 56 ). By this means, the user of the calling-side terminal apparatus  1 A is capable of recognizing that the communicating party checked update of the registered information of the address book. 
     Thus, even in the case where the user of the receiving-side terminal apparatus is not a registered user of the company or the receiving-side terminal apparatus is not capable of supporting the system, it is possible to automatically notify the registered information of the address book of the communicating party by one operation. By this means, the user updating the registered information is capable of collectively notifying a plurality of communicating parties of the updated information. 
     The present invention is not limited to above-mentioned Embodiments 1 and 2, and is capable of being carried into practice with various modifications thereof. For example, it is described in above-mentioned Embodiments 1 and 2 that the server apparatus for generating the update site of the updated information is the same as the server apparatus entrusted with address books, but the invention is not limited thereto, and the server apparatus for generating the update site of the updated information and the server apparatus entrusted with address books may be provided separately from each other. Further, without departing from the scope of the invention, the processing sections and processing procedures are capable of being carried into practice with various modifications thereof as appropriate. Moreover, the invention is capable of being modified as appropriate to be carried into practice without departing from the scope of the invention.
