However, the following embodiments do not limit the claimed invention, and all combinations of features described in the embodiments are included. It is not necessarily essential for the solution of the invention.

  FIG. 1 shows an overview of a communication control apparatus 20 according to an embodiment of the present invention. The communication control device 20 provides status information indicating the status of each user of the plurality of communication terminals 10, for example, presence information indicating the current status of the user, to the registered plurality of communication terminals 10. The communication control device 20 records the terminal identification information of another communication terminal 10 that is permitted to provide the presence information of the one communication terminal 10 in association with the terminal identification information that identifies the one communication terminal 10. A block that records terminal identification information of another communication terminal 10 for which provision of presence information of the one communication terminal 10 is prohibited in association with the contact list and terminal identification information for identifying the one communication terminal 10 With a list. The communication control device 20 is, for example, the SIP server 22 and / or the presence server 24, and is the communication terminal 10 having a part or all of the configuration and functions of the communication control device 20.

  Even when the communication control apparatus 20 according to the present embodiment receives a request for providing presence information again within a predetermined time from the communication terminal 10 of the communication partner who has refused the provision of presence information once. The purpose is to automatically reject the request within the predetermined time.

  First, the communication terminal 10 (B) sends a request for registration to the contact list of the communication terminal 10 (A) included in the presence server 24 to the network 40 so that the presence information of the communication terminal 10 (A) can be referred to. To the presence server 24 (S100). The presence server 24 is a block list in which the terminal identification information for identifying the received communication terminal 10 (B), for example, the telephone number of the communication terminal 10 (B) is associated with the terminal identifier for identifying the communication terminal 10 (A). If it is determined that the registration request is not recorded, the registration request transmitted by the communication terminal 10 (B) is notified to the communication terminal 10 (A) (S102).

  When the communication terminal 10 (A) receives a registration request from the communication terminal 10 (B), the communication terminal 10 (A) displays text data indicating that the registration request has been received on the display unit 172 to inform the user of the communication terminal 10 (A). And whether to accept a registration request from the communication terminal 10 (B). For example, the communication terminal 10 (B) displays the text “Registration request notification has been received from Mr. B.” on the display unit 172 included in the communication terminal 10 (B) and accepts the registration request. An icon 400 that allows the user to select this, and an icon 410 that allows the user to select to reject the registration are displayed.

  When the user selects the icon 400, the communication terminal 10 (A) transmits information indicating that the registration request from the communication terminal 10 (B) is accepted to the presence server 24, and the contact included in the presence server 24. In the list, the terminal identification information of the communication terminal 10 (B) is recorded in association with the terminal identification information of the communication terminal 10 (A). Then, the presence server 24 records the terminal identification information of the communication terminal 10 (B) in the contact list in association with the terminal identification information of the communication terminal 10 (A), and then stores the communication terminal 10 (B) in the contact list. A registration completion notification indicating that the recording has been completed is sent (S106). As a result, the communication terminal 10 (B) can refer to the presence information of the communication terminal 10 (A), and works on the SIP server 22 (S105) to perform half-duplex Push-To-Talk (PTT). ) It is also possible to communicate using a communication method.

  On the other hand, when the user selects the icon 410, the communication terminal 10 (A) transmits information indicating that the registration request from the communication terminal 10 (B) is rejected to the presence server 24. Then, the communication terminal 10 (A) records the terminal identification information of the communication terminal 10 (B) in the block list provided in the presence server 24 in association with the terminal identification information of the communication terminal 10 (A). The presence server 24 records the terminal identification information of the communication terminal 10 (B) in the block list in association with the terminal identification information of the communication terminal 10 (A), and then enters the contact list in the communication terminal 10 (B). A refusal notification indicating that the recording of the file cannot be made is sent (S106).

  In such a case, the presence server 24 adds the communication terminal 10 (B) to the block list until a predetermined time (for example, 72 hours) elapses after the terminal identification information of the communication terminal 10 (B) is recorded in the block list. Record the terminal identification information of B). Then, when the presence server 24 receives a registration request to the contact list of the communication terminal 10 (A) again from the communication terminal 10 (B) within the predetermined time (S108), the presence request 24 Is not notified to the communication terminal 10 (A), and a rejection notification is notified to the communication terminal 10 (B) (S107). Then, the presence server 24 deletes the terminal identification information of the communication terminal 10 (B) recorded in the block list after a predetermined time has elapsed. Subsequently, when the communication control apparatus 20 receives again a registration request to the contact list of the communication terminal 10 (A) from the communication terminal 10 (B), the communication control apparatus 20 notifies the communication terminal 10 (A) of the registration request. Then, the user of the communication terminal 10 (A) is made to select again whether or not to accept a registration request from the communication terminal 10 (B).

  In addition, the communication terminal 10 (A) may include a block list. For example, the communication terminal 10 (A) receives a registration request to the contact list from the communication terminal 10 (B). Then, when the terminal identification information of the communication terminal 10 (B) is recorded in the block list included in the communication terminal 10 (A), the communication terminal 10 (A) communicates with the user of the communication terminal 10 (A). A notification of rejection is notified to the communication terminal 10 (B) without notifying that the registration request to the contact list has been received from 10 (B). Subsequently, the communication terminal 10 (A) records the terminal identification information of the communication terminal 10 (B) in the block list, and after a predetermined time has elapsed, the communication terminal 10 (B) Delete terminal identification information. When the communication terminal 10 (A) receives the registration request again from the communication terminal 10 (B), the communication terminal 10 (A) accepts the registration request from the communication terminal 10 (B) to the user of the communication terminal 10 (A). To select whether or not.

  According to the communication control apparatus 20 according to the present embodiment, information indicating that a registration request from another communication terminal 10 to the contact list of one communication terminal 10 is prohibited is used as terminal identification of the other communication terminal 10. Since a block list that is recorded in association with information is provided, when a registration request is once rejected in one communication terminal 10, the communication control device 20 can automatically reject a registration request from the other communication terminal 10. . Thereby, the user of one communication terminal 10 can ignore a registration request from another communication terminal 10 that does not desire to receive a registration request without performing a complicated operation on the one communication terminal 10. .

  In addition, since the communication terminal 10 includes part or all of the configuration and functions of the block list included in the communication control device 20 according to the present embodiment, the communication terminal 10 may not automatically receive registration requests. The registration request from the communication terminal 10 can be ignored. Furthermore, according to the communication control apparatus 20 according to the present embodiment, even when the terminal identification information is once recorded in the block list, the recorded terminal identification information can be deleted after a predetermined time has elapsed. Thereby, even if the terminal identification information is mistakenly recorded in the block list, the user can select whether to accept the registration request again after a predetermined time has elapsed.

  FIG. 2 shows an example of a functional configuration of the communication control apparatus 20 according to the present embodiment. The communication control device 20 provides status information indicating the status of the user of the first communication terminal to other registered communication terminals (for example, the second communication terminal) other than the first communication terminal. Here, the first communication terminal and the second communication terminal described in the claims are examples of the communication terminal 10 in the above description of FIG. The communication control device 20 includes a provision request receiving unit 200, a response selection control unit 210, a registration information recording unit 220, a response notification unit 230, a response acquisition unit 240, a notification control unit 250, a prohibition information erasing unit 260, and a time measurement unit 270.

Note that the first communication terminal has part or all of the configuration and functions of the communication control device 20, and the first communication terminal also exhibits substantially the same function as the communication control device 20.

  The provision request receiving unit 200 receives request information for requesting provision of status information from the second communication terminal. The request information is a registration request for requesting recording of terminal identification information in the permission information recording unit 224. The permission information recording unit 224 records permission information indicating that provision of status information of the first communication terminal is permitted in association with terminal identification information of another communication terminal 10 different from the first communication terminal. . The permission information recording unit 224 is, for example, a contact list that records terminal identification information for identifying other communication terminals 10 that can receive provision of presence information of the communication terminal 10. The provision request receiving unit 200 supplies the received request information and the terminal identification information of the second communication terminal that has transmitted the request information to the registration information recording unit 220. Further, the provision request receiving unit 200 supplies information indicating that the request information has been received from the second communication terminal to the response selection control unit 210 and the notification control unit 250.

  The registration information recording unit 220 records prohibition information indicating that provision of status information to the second communication terminal is prohibited. Specifically, the prohibition information recording unit 222 included in the registration information recording unit 220 records the prohibition information in association with the terminal identification information of the second communication terminal. More specifically, the prohibition information recording unit 222 records prohibition information in association with terminal identification information designated by the user of the first communication terminal. In addition, the prohibition information recording unit 222 provides status information of the other communication terminals 10 identified by the terminal identification information in association with each of the plurality of terminal identification information identifying each of the other communication terminals 10. Record prohibition information indicating prohibition.

  Further, the prohibition information recording unit 222 records the prohibition information in association with the terminal identification information of the second communication terminal in accordance with a user instruction. Specifically, the prohibition information recording unit 222 responds to the terminal identification information of the second communication terminal when the user rejects the request information for the request information received by the provision request receiving unit 200. And record. For example, when the communication control device 20 is the presence server 24 and / or the SIP server 22, the communication control device 20 provides a provision request notification unit that notifies the communication terminal 10 of the request information received by the provision request reception unit 200. Further, it may be provided. Then, the communication terminal 10 notifies the user of the communication terminal 10 of the request information notified by the provision request notification unit.

  Subsequently, the communication terminal 10 causes the user of the communication terminal 10 to select whether to accept the request information notified by the provision request notification unit. Specifically, the response selection unit included in the communication terminal 10 causes the user to select whether or not to accept the request information. The communication terminal 10 transmits prohibition information to the communication control device 20 when the response selection unit selects not to accept the request information. Then, the response acquisition unit 240 included in the communication control device 20 acquires prohibition information from the communication terminal 10. The response acquisition unit 240 records the prohibition information received from the communication terminal 10 in the prohibition information recording unit 222. In addition, the response acquisition unit 240 supplies information indicating that the prohibition information is recorded in the prohibition information recording unit 222 to the response notification unit 230.

  Further, even when the communication control device 20 is the communication terminal 10, the communication control device 20 may further include a provision request notification unit that notifies the user of the request information received by the provision request reception unit 200. Then, in response to the request information notified by the provision request notification unit, the response acquisition unit 240 allows the user to select whether or not to accept the request information. When the response acquisition unit 240 acquires information indicating that the request information is not accepted from the user, the response acquisition unit 240 records the prohibition information in the prohibition information recording unit 222. The prohibition information recording unit 222 supplies information indicating that the prohibition information has been recorded to the notification control unit 250 and the time measurement unit 270.

  The time measurement unit 270 measures a predetermined time from when the registration information recording unit 220 records the prohibition information. Specifically, the time measuring unit 270 starts measuring a predetermined time from receiving information indicating that the prohibition information has been recorded from the registration information recording unit 220. And the time measurement part 270 complete | finishes measurement of time, when predetermined time passes. When the registration information recording unit 220 records a plurality of pieces of prohibition information, the time measurement unit 270 measures a predetermined time for each of the plurality of pieces of prohibition information. The time measurement unit 270 includes information indicating that measurement of a predetermined time has started and information indicating that measurement of a predetermined time has ended, the response selection control unit 210, the notification control unit 250, and the prohibition This is supplied to the information erasing unit 260.

  The prohibition information erasure unit 260 erases the prohibition information recorded by the registration information recording unit 220 when a predetermined time has elapsed since the registration information recording unit 220 recorded the prohibition information. In addition, the prohibition information erasure unit 260 stores the prohibition information of the number that can be recorded by the registration information recording unit 220 when the registration information recording unit 220 should record prohibition information about the new other communication terminal 10. In the case where it has already been recorded, the prohibition information that has been recorded for the longest time since the registration information recording unit 220 recorded is deleted from the prohibition information recorded by the registration information recording unit 220. Then, the prohibition information erasure unit 260 causes the registration information recording unit 220 to record prohibition information about the new other communication terminal 10. In this case, the prohibition information recording unit 222 supplies the response selection control unit 210 with information indicating that the recorded prohibition information has been deleted by the prohibition information deleting unit 260.

  In addition, the registration information recording unit 220 records permission information indicating that the provision of status information to the second communication terminal is permitted. Specifically, the permission information recording unit 224 included in the registration information recording unit 220 records the permission information in association with the terminal identification information of the second communication terminal. More specifically, the permission information recording unit 224 records the permission information in association with the terminal identification information specified by the user of the first communication terminal. Further, the permission information recording unit 224 provides status information to the other communication terminals 10 identified by the terminal identification information in association with each of the plurality of terminal identification information identifying each of the other communication terminals 10. The permission information indicating that permission is granted is recorded.

  The response notification unit 230 is controlled by the notification control unit 250 so that the provision request receiving unit 200 receives a request from the second communication terminal before a predetermined time elapses after the registration information recording unit 220 records the prohibition information. When the request information is received, the second communication terminal is notified that the second communication terminal cannot receive provision of status information. Specifically, when the user of the first communication terminal selects that the provision of the status information is prohibited according to the request information received by the provision request receiving unit 200, the response notification unit 230 receives the second communication terminal. Notifies the second communication terminal that the status information cannot be provided. When the response notification unit 230 receives information indicating that the prohibition information has been recorded in the prohibition information recording unit 222 from the response acquisition unit 240, the user of the first communication terminal prohibits the provision of status information. It judges that it selected, and notifies a 2nd communication terminal that the 2nd communication terminal cannot receive provision of status information.

  Further, the response notification unit 230 is controlled by the notification control unit 250 when the user of the first communication terminal selects to prohibit the provision of the status information according to the request information received by the provision request receiving unit 200. Then, the second communication terminal is notified that the provision of the status information has been rejected. Then, the response notifying unit 230 indicates that there is no response from the user of the first communication terminal when there is no response from the user of the first communication terminal with respect to the request information received by the provision request receiving unit 200. Notify the communication terminal. Further, the response notification unit 230 notifies the second communication terminal that there is no response from the user of the first communication terminal when the prohibition information is recorded in the registration information recording unit 220. That is, the response notification unit 230 sends a response to the request information requested by the second communication terminal from the user of the first communication terminal to the second communication terminal, and to the request information received from the first communication terminal. The second communication terminal is notified that there is no response from the user of the first communication terminal, which shows the same content as when the user refuses.

  As a result, regardless of whether the first communication terminal rejects the registration request or the first communication terminal cannot respond to the registration request, the registration request is not permitted for the user of the second communication terminal. The same predetermined message is notified. Therefore, it is possible to prevent the user of the second communication terminal from having a negative feeling when the registration request is rejected by the first communication terminal.

  When the provision request receiving unit 200 receives the request information from the second communication terminal after a predetermined time has elapsed since the registration information recording unit 220 recorded the prohibition information, the response selection control unit 210 receives the request information from the second communication terminal. 2. The user of the first communication terminal is allowed to select whether or not the provision of status information to the communication terminal is prohibited. For example, when the communication control device 20 is the presence server 24 and / or the SIP server 22, the response selection control unit 210 transmits the request information to the first communication terminal, and transmits the status information to the second communication terminal. The user of the first communication terminal is allowed to select whether to prohibit the provision. In addition, the response selection control unit 210 receives the request information from the second communication terminal after the prohibition information deletion unit 260 deletes the prohibition information recorded by the registration information recording unit 220. The user of the first communication terminal is allowed to select whether or not the provision of status information to the second communication terminal is prohibited. The response selection control unit 210 records the permission information in the permission information recording unit 224 when the user of the first communication terminal accepts the request information. The response selection control unit 210 records the prohibition information in the prohibition information recording unit 222 when the user of the first communication terminal does not accept the request information.

  When the communication control device 20 is the presence server 24 and / or the SIP server 22, the response selection control unit 210 transmits request information to the first communication terminal, and transmits status information to the second communication terminal. The user of the first communication terminal is allowed to select whether to prohibit the provision. When the user of the first communication terminal selects that the provision of the status information to the second communication terminal is prohibited according to the request information received by the provision request receiving unit 200, the registration information recording unit 220 Record the prohibition information again. The response notifying unit 230 receives the request information from the second communication terminal before the predetermined time elapses after the registration information recording unit 220 records the prohibition information again. In addition, the second communication terminal is notified that the second communication terminal cannot receive the provision of the status information.

  When the provision request receiving unit 200 receives the request information from the second communication terminal before the predetermined time has elapsed since the registration information recording unit 220 recorded the prohibition information, the notification control unit 250 The second notification terminal 230 cannot receive the status information from the response notification unit 230 without allowing the user of the first communication terminal to select whether to prohibit the provision of the status information to the communication terminal. 2 Notify the communication terminal. When the communication control device 20 is the presence server 24 and / or the SIP server 22, the second communication terminal provides status information to the response notification unit 230 without notifying the request information to the first communication terminal. The second communication terminal is notified that it cannot be received.

  When the communication control device 20 is the communication terminal 10, the registration information recording unit 220 records user information indicating the user of the communication terminal 10 in association with the terminal identification information of the communication terminal 10. You may have a book. In such a case, when the provision request receiving unit 200 receives the request information from the second communication terminal, the communication terminal 10 records the terminal identification information of the second communication terminal that has transmitted the request information in the phone book. The user information of the second communication terminal is notified to the user of the communication terminal 10. On the other hand, when the terminal identification information of the second communication terminal is not recorded in the telephone directory, the terminal identification information of the second communication terminal is notified to the user of the communication terminal 10. The user information is, for example, text data indicating the user's name or name, and is image data or the like associated with the user in advance.

  According to the communication control apparatus 20 according to the present embodiment, prohibition information indicating prohibition of provision of status information of the first communication terminal can be recorded in association with the terminal identification information of the second communication terminal. If the registration request is once rejected at the communication terminal, the communication control device 20 can automatically reject the registration request from the second communication terminal. As a result, the user of the first communication terminal simply designates the second communication terminal that does not want to receive the registration request once, and automatically requests the registration request from the second communication terminal without requiring a complicated operation from the user. Can be rejected.

  Further, when the communication control device 20 according to the present embodiment is the communication terminal 10, the communication terminal 10 itself can automatically reject a registration request from the second communication terminal. Furthermore, according to the communication control apparatus 20 according to the present embodiment, even when the prohibition information is recorded once, the recorded prohibition information can be erased after a predetermined time has elapsed. Thereby, even if the prohibition information is erroneously recorded, it is possible to give the user an opportunity to select whether or not to accept the registration request again.

  FIG. 3 shows an example of the data structure of the prohibition information recording unit 222 according to this embodiment. The prohibition information recording unit 222 is associated with the communication terminal identification information for identifying each of the plurality of communication terminals 10 and prohibits the provision of status information of other communication terminals 10 of the plurality of communication terminals 10. Record prohibited information. The prohibition information recording unit 222 may record the communication terminal identification information of the communication terminals 10 for which provision of status information of the plurality of communication terminals 10 is prohibited in association with each of the plurality of communication terminals 10. . The communication terminal identification information is an example of the terminal identification information in the above description of FIGS. 1 to 2, and is, for example, a telephone number.

  The prohibition information recording unit 222 may further store a recording date and time when the prohibition information is recorded in association with the communication terminal identification information. The prohibition information erasure unit 260 reads the recording date and time recorded by the prohibition information recording unit 222 when the prohibition information recording unit 222 has already recorded the number of prohibition information that can be recorded. The prohibition information that has passed the longest time since the recording by 222 is deleted.

  FIG. 4 shows an example of the flow of processing in the communication terminal 10 and the communication control apparatus 20 according to the present embodiment. First, the communication terminal 10 (A) transmits a contact list registration request to the communication terminal 10 (B) (S400). For example, the communication terminal 10 (A) transmits an XCAP PUT-200OK message (AUID = resource-lists Add B) to the communication control device 20 (A) on the communication terminal 10 (A) side (S405). The communication control device 20 (A) is, for example, the presence server 24 on the communication terminal 10 (A) side. Then, the communication control device 20 (A) transmits a SUBSCRIBE-202 Accepted message (Presence) to the communication control device 20 (B) on the communication terminal 10 (B) side (S410).

  Subsequently, the communication control apparatus 20 (B) transmits a NOTIFY-200 OK message ((info) state = pending) to the communication terminal 10 (B) in response to the SUBSCRIBE-202 Accepted message received from the communication control apparatus 20 (A). (S415). The communication terminal 10 (B) notifies the registration request to the user of the communication terminal 10 (B) in response to the received NOTIFY-200OK message (S420). When the user of the communication terminal 10 (B) selects to reject the registration request from the communication terminal 10 (A) in response to the registration request, that is, when “No” is selected (S425). The communication terminal 10 (B) transmits an XCAP PUT-200 OK message (AUID = pres-rules, A's “sub-handling” = “block”) to the communication control device 20 (B) (S440).

  After receiving the SUBSCRIBE-202 Accepted message (S410), the communication control device 20 (B) transmits a NOTIFY-200 OK message ((presence) state = pending) to the communication control device 20 (A) (S430). . Then, after receiving the NOTIFY-200OK message (S430), the communication control device 20 (A) transmits the NOTIFY-200OK message ((eventlist) state = pending) to the communication terminal 10 (A) (S435). Subsequently, after receiving the XCAP PUT-200OK message from the communication terminal 10 (B) (S440), the communication control device 20 (B) sends a NOTIFY-200OK message ((presence) to the communication control device 20 (A). ) State = terminate, reason = reject) are transmitted to the communication control apparatus 20 (A) (S445).

  After receiving the NOTIFY-200 OK message (S445), the communication control device 20 (A) transmits a NOTIFY-200 OK message ((eventlist) state = terminated, reason = reject) to the communication terminal 10 (A) (S450). . Then, the communication terminal 10 (A) transmits an XCAP PUT-200 OK message (AUID = resource-lists Delete B) to the communication control apparatus 20 (A) (S455). Subsequently, the communication terminal 10 (A) notifies the user of the communication terminal 10 (A) of an ignorance response and notifies that the presence information of the communication terminal 10 (B) cannot be referred to (S460).

  FIG. 5 shows an example of the flow of processing in the communication terminal 10 and the communication control apparatus 20 according to the present embodiment. First, the communication terminal 10 (A) transmits a contact list registration request to the communication terminal 10 (B) (S500). The communication terminal 10 (A) transmits an XCAP PUT-200 OK message (AUID = resource-lists Add B) to the communication control device 20 (A) on the communication terminal 10 (A) side (S505). Then, the communication control device 20 (A) transmits a SUBSCRIBE-202 Accepted message (Presence) to the communication control device 20 (B) on the communication terminal 10 (B) side (S510). Subsequently, the communication control apparatus 20 (B) transmits a NOTIFY-200 OK message ((info) state = pending) to the communication terminal 10 (B) in response to the SUBSCRIBE-202 Accepted message received from the communication control apparatus 20 (A). (S515). The communication terminal 10 (B) notifies the registration request to the user of the communication terminal 10 (B) in response to the received NOTIFY-200OK message (S520).

  When the user of the communication terminal 10 (B) selects to permit the registration request from the communication terminal 10 (A) in response to the registration request, that is, when “Yes” is selected (S525). The communication terminal 10 (B) transmits an XCAP PUT-200 OK message (AUID = resource-lists Add A) to the communication control apparatus 20 (B) (S540). After receiving the SUBSCRIBE-202 Accepted message (S510), the communication control device 20 (B) transmits a NOTIFY-200 OK message ((presence) state = pending) to the communication control device 20 (A) (S530). .

  Then, after receiving the NOTIFY-200OK message (S530), the communication control device 20 (A) transmits the NOTIFY-200OK message ((eventlist) state = pending) to the communication terminal 10 (A) (S535). Subsequently, after receiving the XCAP PUT-200 OK message from the communication terminal 10 (B) (S540), the communication control device 20 (B) sends a NOTIFY-200 OK message ((presence) to the communication control device 20 (A). ) (State = active) is transmitted to the communication control apparatus 20 (A) (S545). Then, the communication control device 20 (A) transmits a NOTIFY-200 OK message ((event list) state = active) to the communication terminal 10 (A) (S550). The communication terminal 10 (A) that has received the NOTIFY-200 OK message (state = active) from the communication control device 20 (A) notifies the user of the communication terminal 10 (A) of a permission response notification (S555). This completes registration.

  On the other hand, after receiving the XCAP PUT-200OK message from the communication terminal 10 (B) (S540), the communication control device 20 (B) transmits a SUBSCRIVE-200OK message (presence) to the communication control device 20 (A). (S560). After receiving the SUBSCRIVE-200OK message from the communication control apparatus 20 (A), the communication control apparatus 20 (B) transmits a NOTIFY-200OK message ((presence) state = active) to the communication control apparatus 20 (B). (S565), a NOTIFY-200OK message ((winfo) state = active) is transmitted to the communication terminal 10 (A) (S570). Then, after receiving the NOTIFY-200OK message from the communication control apparatus 20 (A), the communication control apparatus 20 (B) transmits a NOTIFY-200OK message ((eventlist) state = active) to the communication terminal 10 (B). (S575). After receiving the NOTIFY-200 OK message, the communication terminal 10 (B) notifies the user of the communication terminal 10 (B) of a permission response (S580). This completes registration.

  FIG. 6 shows an example of the flow of processing in the communication control apparatus 20 according to the present embodiment. Specifically, when the communication control device 20 is the presence server 24 and / or the SIP server 22, the limit on the number of block rules (for example, prohibition information) that can be held in the control-side block list included in the communication control device 20 An example of the flow of processing when exceeding is shown. The communication control device 20 transmits a NOTIFY-200 OK message ((info) state = pending) to the communication terminal 10 in response to a registration request from another communication terminal 10 (S600). When receiving the NOTIFY-200 OK message, the communication terminal 10 notifies the user of the communication terminal 10 of a registration request (S605).

  Here, when the user of the communication terminal 10 selects “No” to reject the registration request (S610), the communication terminal 10 sends an XCAP PUT message (AUID = pres-rules, A) to the communication control device 20. 's "sub-handling" = "block") is transmitted (S615). Specifically, the communication terminal 10 transmits information including the new block rule and the existing block rule to the communication control apparatus 20 in the XCAP PUT message. For example, the communication terminal 10 associates the block rule already recorded in the terminal block list included in the communication terminal 10 with the terminal identification information of another communication terminal 10 that the user has rejected the registration request. Record the new block rule.

  The communication control device 20 determines whether or not the limit of the block rule that can be held in the control side block list is exceeded, and when it is determined that the limit is exceeded, the control side block list sets the block rule. A 409 Conflict “Document to large” message, which is an error message indicating that recording cannot be performed, is transmitted to the communication terminal 10 (S620). When the communication terminal 10 receives the error message, the information obtained by deleting the oldest block rule from among the block rules held by the communication terminal 10 is renewed as an XCAP PUT message (AUID = pres-rules, A ′. s "sub-handling" = "block") and transmitted to the communication control apparatus 20. And the communication control apparatus 20 records a block rule in the control side block list with which the communication control apparatus 20 is provided, and transmits the 200OK message which is the confirmation information which recording completed to the communication terminal 10 (S630).

  FIG. 7 shows an example of the processing flow in the communication terminal 10 according to the present embodiment. Specifically, an example of the flow of processing when the limit of the number of block rules (for example, prohibition information) that can be held in the terminal-side block list provided in the communication terminal 10 is exceeded is shown. First, the communication control device 20 transmits a NOTIFY-200 OK message ((info) state = pending) to the communication terminal 10 in response to a registration request from another communication terminal 10 of the communication terminal 10 (S700). When receiving the NOTIFY-200 OK message, the communication terminal 10 notifies the user of the communication terminal 10 of a registration request (S705).

  If the user of the communication terminal 10 selects “No” to reject the registration request (S710), the communication terminal 10 sends an XCAP PUT message (AUID = pres-rules, A ′) to the communication control device 20. s "sub-handling" = "block") is transmitted (S715), and the communication terminal 10 adds another communication terminal to the communication terminal 10 to which the user has rejected the registration request in the terminal-side block list of the communication terminal 10 A new block rule is recorded in association with the 10 terminal identification information. Here, when the limit of the number of block rules that can be recorded in the terminal block list is reached, the communication terminal 10 deletes the oldest block rule among the block rules held by the communication terminal 10. Then, the communication terminal 10 records a new block rule in the terminal-side block list in association with the terminal identification information of another communication terminal 10 of the communication terminal 10 for which the user has rejected the registration request.

  FIG. 8 shows an outline of a communication terminal 10 according to another embodiment. The communication terminal 10 is a communication terminal 10 whose communication is controlled based on communication settings registered in the external communication control device 20. The communication terminal 10 is a communication terminal that transmits and receives communication data, and is specifically a mobile phone terminal. For example, the communication terminal 10 may be a mobile phone terminal that performs voice data packet communication using the PTT communication method, which is a half-duplex communication method. The communication terminal 10 may be a notebook personal computer, a PDA, a portable information terminal such as a game machine, and a desktop PC having a function of transmitting and receiving communication data.

  When the communication terminal 10 according to the present embodiment makes a response to a registration request to the contact list from another communication terminal 10 when the communication terminal 10 is out of service area, the communication terminal 10 records the response content, It is an object to transmit the response content recorded when 10 returns to the service area to the communication control device 20.

  First, the communication terminal 10 (A) requests the presence server 24 as an example of the communication control device 20 to provide presence information of the communication terminal 10 (B) via the communication relay device 30 (A) and the network 40. Request information to be transmitted is transmitted (S200). Presence information is an example of status information. The presence server 24 is a block list in which terminal identification information for identifying the received communication terminal 10 (A), for example, a telephone number of the communication terminal 10 (A) is associated with a terminal identifier for identifying the communication terminal 10 (B). If it is determined that the information is not recorded in the communication terminal 10 (A), the registration request transmitted from the communication terminal 10 (A) is notified to the communication terminal 10 (B) (S202).

  The communication terminal 10 (B) notifies the user of the request information notified by the presence server 24, and allows the user to select whether to permit or reject the request information. When the user selects to reject the request information, the communication terminal 10 (B) transmits prohibition information indicating that the presence information is not provided to the communication terminal 10 (A) to the presence server 24. The presence server 24 records the prohibition information received from the communication terminal 10 (B) for a predetermined time in association with the terminal identifier for identifying the communication terminal 10 (A). As a result, even if the communication terminal 10 (A) transmits request information to the communication terminal 10 (A) again within the predetermined time, the presence server 24 sends the communication terminal 10 (A). ) Is automatically notified that the presence information cannot be referred to (S206).

  Here, in the communication terminal 10 (B), when the user selects to permit or reject the request information from the communication terminal 10 (A), the communication terminal 10 (B) exists outside the service area. Consider the case. That is, the communication terminal 10 (B) has an electromagnetic wave intensity from the communication relay device 30 (B) that relays communication between the communication terminal 10 (B) and the presence server 24 being smaller than a predetermined reference value. When communication is not possible, the communication terminal 10 (B) records communication setting information to be transmitted to the presence server 24. When the communication terminal 10 (B) returns to the service area, the recorded communication setting information is automatically transmitted to the presence server 24 (S204). Thus, the user can automatically transmit and register the communication setting information to the presence server 24 without grasping whether the communication terminal 10 (B) is in the area or not. .

  Here, when the communication terminal 10 (B) has recorded the communication setting information to be transmitted to the presence server 24, the communication terminal 10 (B) transmits the communication setting information to the presence server 24 for the user of the communication terminal 10 (B). A message indicating that the message is automatically transmitted without any operation is displayed on the display unit 172. For example, when the communication terminal 10 (B) moves out of service after receiving a registration request from the communication terminal 10 (A) and the user selects to reject the registration request, the display unit 172 displays “ "Reject registration accepted" is displayed. Further, when the communication terminal 10 (B) receives the registration request from the communication terminal 10 (A) and selects to reject the registration request received while remaining in the service area, the communication terminal 10 (B) When the communication setting information is transmitted from, the display unit 172 displays “Rejected registration accepted.”

  As a result, the user of the communication terminal 10 (B) can grasp that the registration request from the communication terminal 10 (A) is automatically set to a state in which the communication terminal 10 (B) automatically rejects the communication request. It can be easily recognized that after the terminal 10 (B) transitions to the area, it is not necessary for the user to register and reject the registration request from the communication terminal 10 (A).

  FIG. 9 shows an example of a functional configuration of the communication terminal 10 according to another embodiment. The communication terminal 10 includes a communication setting acquisition unit 100, a communication setting information recording unit 110, a transmission control unit 120, a communication setting information transmission unit 130, a communication availability determination unit 140, an electric field strength monitoring unit 150, a user interface control unit 160, and a user. The interface unit 170 includes a display unit 172 and an audio output unit 174. Note that the communication terminal 10 may further include some or all of the functions and configurations of the communication control device 20 described in the above description of FIGS.

  The communication setting acquisition unit 100 acquires communication setting information indicating the communication setting of the communication terminal 10 instructed by the user. The communication setting information is, for example, prohibition information indicating that provision of status information indicating a user status to other communication terminals 10 is prohibited. Further, the communication setting information may be permission information indicating that the status information is permitted to be provided to other communication terminals 10. Further, the communication setting information may be information for setting a communication service to be added to communication in the communication terminal 10 such as transfer setting and answering machine setting. For example, the communication setting acquisition unit 100 acquires a communication setting indicating that the communication control device 20 registers the prohibition information in association with the terminal identification information instructed by the user. The communication setting acquisition unit 100 supplies the acquired communication setting information to the communication setting information recording unit 110 and the transmission control unit 120.

  The communication control device 20 is associated with terminal identification information for identifying the other communication terminal 10, permission information indicating that provision of status information is permitted, or prohibition indicating that provision of status information is prohibited. Information is registered. And the communication control apparatus 20 transmits the status information of the said communication terminal 10 to the other communication terminal 10 matched with the permission information. On the other hand, the communication control device 20 does not transmit the status information of the communication terminal 10 to other communication terminals 10 associated with the prohibition information. Note that the status information is, for example, presence information of the communication terminal 10.

  The electric field strength monitoring unit 150 monitors the electric field strength of the electromagnetic wave from the external communication relay device 30 that relays communication between the communication terminal 10 and the communication control device 20. The electric field strength monitoring unit 150 supplies information indicating the electric field strength of the electromagnetic wave from the communication relay device 30 to the communication availability determination unit 140. The communication possibility determination unit 140 determines whether communication between the communication terminal 10 and the communication control device 20 is possible. Specifically, the communication feasibility determining unit 140 analyzes information indicating the electric field strength of the electromagnetic wave received from the electric field strength monitoring unit 150, and the electric field strength monitored by the electric field strength monitoring unit 150 is a predetermined standard. When the value is exceeded, it is determined that the communication terminal 10 and the communication control device 20 can communicate with each other. The communication availability determination unit 140 supplies the determination result to the communication setting information recording unit 110, the transmission control unit 120, and the interface control unit 160.

  The communication setting information recording unit 110 records the communication setting information acquired by the communication setting acquisition unit 100 when the communication availability determination unit 140 determines that the communication terminal 10 and the communication control device 20 cannot communicate with each other. That is, the communication setting information recording unit 110 receives the communication acquired from the communication setting acquisition unit 100 when the determination result received from the communication availability determination unit 140 indicates that the communication terminal 10 and the communication control device 20 cannot communicate with each other. Record the setting information. The communication setting information recording unit 110 is controlled by the transmission control unit 120 and supplies the recorded communication setting information to the transmission control unit 120.

  The transmission control unit 120 records the communication setting information when the communication availability determination unit 140 determines that the communication terminal 10 and the communication control device 20 can communicate after the communication setting information recording unit 110 records the communication setting information. The communication setting information recorded by the unit 110 is transmitted from the communication setting information transmitting unit 130 to the communication control device 20 to be registered in the communication control device 20. The transmission control unit 120 supplies the interface control unit 160 with information indicating whether or not to transmit the communication setting information from the communication setting information transmission unit 130.

  The communication setting information transmission unit 130 displays the communication setting information acquired by the communication setting acquisition unit 100 when the communication availability determination unit 140 determines that the communication terminal 10 and the communication control device 20 can communicate with each other. To be registered in the communication control device 20. Specifically, the communication setting information transmission unit 130 transmits the communication setting information acquired by the communication setting acquisition unit 100 to the communication control device 20, so that the communication control device 20 has terminal identification information designated by the user. The prohibition information is registered in association.

  The user interface unit 170 supports the user's operation on the communication terminal 10 when the user instructs the communication setting of the communication terminal 10. When the communication interface information determining unit 140 determines that the communication terminal 10 and the communication control device 20 can communicate with each other, the communication setting information transmitting unit 130 sends the communication setting information to the communication control device 20. The user interface unit when the communication setting information recording unit 110 records the communication setting information when the communication terminal 10 and the communication control device 20 cannot communicate with each other. The same notification is sent from 170 to the user.

  Specifically, the user interface unit 170 includes a display unit 172 that displays contents for supporting user operations on the communication terminal 10. Then, the communication setting information transmission unit 130 transmits the communication setting information to the communication control device 20 when the communication control unit 160 determines that the communication terminal 10 and the communication control device 20 can communicate with each other. On the display unit 172 when the communication setting information recording unit 110 records the communication setting information when the communication permission determination unit 140 determines that the communication terminal 10 and the communication control device 20 cannot communicate with each other. Display the same display data.

  In addition, the user interface unit 170 includes a voice output unit 174 that notifies the content that supports the user operation on the communication terminal 10 by voice. Then, the communication setting information transmission unit 130 transmits the communication setting information to the communication control device 20 when the communication control unit 160 determines that the communication terminal 10 and the communication control device 20 can communicate with each other. The voice output unit 174 when the communication setting information recording unit 110 records the communication setting information when the communication determination unit 140 determines that the communication terminal 10 and the communication control device 20 cannot communicate with each other. May output the same audio data.

  Further, when the communication terminal 10 is turned on, the communication terminal 10 displays a list of the presence information of other communication terminals 10 on the display unit 172 and allows the user to refer to the presence information of the communication terminal 10. May be further provided to the presence server 24 periodically and automatically.

  The presence processing unit works with the presence server 24 to acquire presence information of a plurality of other communication terminals 10 different from the communication terminal 10, and transmits the presence information of the communication terminal 10 to the presence server 24. The presence information transmission unit to be recorded in the presence server 24 and the communication terminal 10 to be able to use the presence information and to provide the presence information of the communication terminal 10 when the communication terminal 10 is powered on. The activation condition recording unit in which a predetermined procedure is recorded, and the presence information acquisition unit, presence information transmission unit, and activation condition recording unit automatically when the communication terminal 10 is turned on. It has an automatic starting part which supplies electric power and starts each.

  Specifically, when the communication terminal 10 is powered on, the automatic activation unit detects the power activation and activates the presence information acquisition unit, presence information transmission unit, and activation condition recording unit. In the activation condition recording unit, for example, the IMS (IP Multimedia Subsystem) setting is ON, network automatic adjustment is performed, and network availability is provided so that presence information can be used in the communication terminal 10. When it is in the middle, an automatic activation condition for automatically acquiring / providing presence information is recorded.

  When the automatic activation unit determines that the automatic activation condition recorded by the activation condition recording unit is satisfied, the automatic activation unit causes the presence information acquisition unit to automatically acquire presence information of a plurality of other communication terminals 10 and The information transmitting unit automatically transmits the presence information of the communication terminal 10 to the presence server 24. With this configuration, the communication terminal 10 automatically acquires the presence information of the other communication terminal 10 and notifies the presence server 24 of the presence information of the communication terminal 10 only by turning on the power of the communication terminal 10. Can be executed. Further, the automatic activation unit may automatically execute transmission of a Poc (Push to Talk over Cellular) setting regarding acquisition of Watcher information and a PTT communication method.

  As a result, the communication terminal 10 transitions the state of the communication terminal 10 to a state where the communication terminal 10 can automatically receive the presence service and the PTT communication service when the communication terminal 10 is turned on and is in a standby state. Can be made.

  According to the communication terminal 10 according to the present embodiment, when the user sets predetermined communication setting information in the communication terminal 10, even if the communication terminal 10 is out of the service area, the setting content is recorded. In addition, the setting contents recorded when the communication terminal 10 returns to the service area can be automatically transmitted to the communication control device 20 for registration. Thereby, the user of the communication terminal 10 does not always have to confirm whether or not the communication terminal 10 has returned to the service area, and the communication setting information desired by the user is automatically transmitted to the communication control device 20. You can register.

  FIG. 10 shows an example of the flow of processing in the communication terminal 10 according to another embodiment. First, when request information for requesting provision of status information of the communication terminal 10 is transmitted from another communication terminal 10 different from the communication terminal 10 to the communication control apparatus 20, the communication control apparatus 20 A NOTIFY-200 OK message ((info) state = pending) is transmitted (S1000). When receiving the NOTIFY-200 OK message, the communication terminal 10 notifies the user of the communication terminal 10 of a registration request (S1005). When the user selects “No” in response to the registration request (S1010), the communication terminal 10 records prohibition information in a block list included in the communication terminal 10 (S1025).

  Then, the communication terminal 10 transmits an XCAP PUT-200 OK message (AUID = pres-rules, A ′s “sub-handling” = “block”) to the communication control device 20 (S1015). When the communication control device 20 receives the XCAP PUT-200 OK message, the communication control device 20 records prohibition information in association with the terminal identification information of the other communication terminal 10 in the block list included in the communication control device 20. Thereby, in both the communication control apparatus 20 and the communication terminal 10, since the terminal identification information of the other communication terminal 10 in which the user of the communication terminal 10 refused the registration request can be recorded in the block list, the other communication terminal 10 When the registration request is transmitted again, the registration request from the other communication terminal 10 can be surely rejected.

  FIG. 11 shows an example of a process flow in the communication terminal 10 according to another embodiment. First, when request information for requesting provision of status information of the communication terminal 10 is transmitted from another communication terminal 10 different from the communication terminal 10 to the communication control apparatus 20, the communication control apparatus 20 A NOTIFY-200 OK message ((info) state = pending) is transmitted (S1100). When receiving the NOTIFY-200 OK message, the communication terminal 10 notifies the user of the communication terminal 10 of a registration request (S1155).

  Here, when the communication terminal 10 moves out of the service area (S1120), when the user selects “No” in response to the registration request (S1125), the communication terminal 10 is a terminal of another communication terminal 10. The prohibition information is recorded in association with the identification information. When the communication terminal 10 returns to the service area (S1130), the communication terminal 10 sends an XCAP PUT-200OK message (AUID = pres-rules, A's “sub-handling” = “block”) to the communication control device 20. ) Is transmitted (S1140). That is, the prohibition information is recorded in the block list of the communication control device 20 when the communication terminal 10 returns to the service area.

  Here, even if the registration request is transmitted from the communication control device 20 immediately after the communication terminal 10 returns to the service area, the communication terminal 10 records the prohibition information. Do not process. That is, even if the NOTIFY-200 OK message ((info) state = pending) is received from the communication control device 20 immediately after the communication terminal 10 returns to the service area (S1135), the communication terminal 10 is not connected to another communication terminal. Since the prohibition information indicating that the registration request from 10 is not accepted is recorded, no processing is performed.
