A plurality of information terminals 2-1 to 2-n (hereinafter also simply referred to as information terminals 2) associated with each of ˜1-n on a one-to-one basis, a SIP server 3 accommodating the IP extension telephone terminal 1, It is configured with. Here, the IP extension telephone terminal 1, the information terminal 2, and the SIP server 3 are connected to the LAN 5, and the LAN 5 is connected to the WAN 6 via the router 4. The WAN 6 is connected to an IP telephone terminal 7 which is a call partner terminal.

  The SIP server 3 executes call control processing in cooperation with the IP extension telephone terminal 1 in accordance with SIP (Session Initiation Protocol), and between the IP extension telephone terminal 1 and the IP telephone terminal 7 or between the IP extension telephone terminals 1. Establish a session (call path). Further, the SIP server 3 has a group incoming function, and when an incoming call is received from the WAN 6 to a telephone number (group number) assigned to an arbitrary group, the IP extension telephone terminal 1 belonging to this group. Are called all at once.

  The IP extension telephone terminal 1 cooperates with the SIP server 3 to execute call control processing according to SIP, and establishes a session with the IP telephone terminal 7 or another IP extension telephone terminal 1. Also, the IP extension telephone terminal 1 performs voice recognition processing on the call data with the partner terminal, extracts a keyword, specifies a theme associated with the keyword in advance, and uses this theme as its own IP extension telephone terminal. 1 to the paired information terminal 2.

  The information terminal 2 manages the group to which the IP extension telephone terminal 1 paired with the information terminal 2 belongs, and the group previously associated with the theme received from the IP extension telephone terminal 1 The IP extension telephone terminal 1 is specified as a group to participate in (participating group), and the SIP server 3 is requested to register the IP extension telephone terminal 1 paired with the own information terminal 2 in the specified participation group. Thereby, the IP extension telephone terminal 1 paired with the own information terminal 2 belongs to the specified participating group. In addition, the information terminal 2 sends the IP extension telephone terminal 1 paired with the information terminal 2 to the group name and group number of the identified participating group and the telephone of each of the other IP extension telephone terminals 1 belonging to the participating group. In addition to notifying participation group information including book data, each of the other IP extension telephone terminals 1 belonging to the specified participation group has a group name, a group number of the participating group and an IP extension paired with the own information terminal 2 The group participation terminal information including the telephone directory data of the telephone terminal 1 is transmitted.

  FIG. 2 is a sequence diagram for explaining an operation example of the IP telephone system according to the present embodiment.

  As shown in the figure, it is assumed that the IP extension telephone terminal 1-1 starts a call with the IP telephone terminal 7 on the WAN 6 side (S100). During a call, the IP extension telephone terminal 1-1 converts the call data into text data by voice recognition processing (S101). Thereafter, when the call with the IP telephone terminal 7 is terminated (S102), the IP extension telephone terminal 1-1 extracts a keyword satisfying the theme specific condition prepared in advance from the text data converted from the call data. Try (S103). Then, a theme associated in advance with the extracted keyword is specified (S104), and this theme is transmitted to the information terminal 2-1 paired with the own IP extension telephone terminal 1-1 (S105).

  When the information terminal 2-1 receives the theme from the IP extension telephone terminal 1-1 paired with the information terminal 2-1, the information terminal 2-1 starts from the electronic mail and the electronic document file stored in the information terminal 2-1. Then, an electronic mail or electronic document file including this theme is searched (S106). If there is such an e-mail or electronic document file, it is determined that there is a track record of handling this theme, and a group previously associated with this theme is specified as a participating group (S107). Then, it is determined whether or not the IP extension telephone terminal 1-1 belongs to the identified participating group (S108).

  Here, when the IP extension telephone terminal 1-1 already belongs to the identified participating group, the information terminal 2-1 extends the expiration date of the belonging of the IP extension telephone terminal 1-1 to the participating group.

  On the other hand, when the IP extension telephone terminal 1-1 does not belong to the identified participating group, the information terminal 2-1 sets the expiration date of the belonging of the IP extension telephone terminal 1-1 to the participating group, In order to make the IP extension telephone terminal 1-1 belong to this participating group, a group registration request is generated with the designation of the group number of the participating group and the extension number of the IP extension telephone terminal 1-1. It transmits to the server 3 (S109). In response to this, the SIP server 3 additionally registers the extension number of the IP extension telephone terminal 1-1 to the extension number associated with the group number specified in the group registration request, and the IP extension telephone terminal 1 -1 belongs to the participating group (S110).

  The information terminal 2-1 also has the group number of the participating group and the telephone directory data (extension number, address information, user information) of the IP extension telephone terminals 1 other than the IP extension telephone terminal 1-1 belonging to this participation group. Etc.) is generated. Then, this participation group information is transmitted to the IP extension telephone terminal 1-1 (S111). In response to this, the IP extension telephone terminal 1-1 uses the group number included in the participation group information and the phone book data of the other IP extension telephone terminal 1 as a group to which the own IP extension telephone terminal 1-1 belongs. As group information.

  Further, the information terminal 2-1 generates group participation terminal information including the group number of the participating group and the telephone directory data (extension number, address information, user information, etc.) of the IP extension telephone terminal 1-1. And this group participating terminal information is transmitted to each IP extension telephone terminal 1 other than the IP extension telephone terminal 1-1 which belongs to this participating group (S112). In response to this, each IP extension telephone terminal 1 other than the IP extension telephone terminal 1-1 belonging to this participation group adds the IP extension telephone terminal to the group information of the group number included in the group participation terminal information. 1-1 phone book data is added.

  Thereafter, the information terminal 2-1 monitors the expiration date of the affiliation of the IP extension telephone terminal 1-1 for the participating group to which the IP extension telephone terminal 1-1 newly belongs. If the expiration date has passed (S113), this participation group is set as a group (withdrawal group) from which the IP extension telephone terminal 1-1 should leave, and the IP extension telephone terminal 1-1 is withdrawn from the withdrawal group. At the same time, a group registration deletion request accompanied with designation of the group number of the withdrawal group and the extension number of the IP extension telephone terminal 1-1 is generated, and this group registration deletion request is transmitted to the SIP server 3 (S114). In response, the SIP server 3 deletes the extension number of the IP extension telephone terminal 1-1 associated with the group number specified in the group registration deletion request (S115).

  Further, the information terminal 2-1 generates withdrawal group information accompanied by designation of the group name and group number of the withdrawal group. Then, this withdrawal group information is transmitted to the IP extension telephone terminal 1-1 (S116). In response to this, the IP extension telephone terminal 1-1 deletes the group information of the withdrawal group specified by the group number specified by the withdrawal group information.

  Further, the information terminal 2-1 generates group withdrawal terminal information including the group name and group number of the withdrawal group and the telephone directory data of the IP extension telephone terminal 1-1. Then, this group withdrawal terminal information is transmitted to each IP extension telephone terminal 1 other than the IP extension telephone terminal 1-1 belonging to this withdrawal group (S117). In response to this, each IP extension telephone terminal 1 other than the IP extension telephone terminal 1-1 belonging to this withdrawal group uses the IP extension telephone terminal from the group information of the group number included in the group withdrawal terminal information. The phone book data 1-1 is deleted.

  Here, the information terminal 2-1 generates and transmits the group participation terminal information and the group withdrawal terminal information. However, the SIP server 3 that has received the group registration request or the group registration deletion request may perform the transmission and reception. Good.

To share group information.

  The participation group specifying unit 212 selects a group (participating group) to which the IP extension telephone terminal 1 should participate based on the theme received from the IP extension telephone terminal 1 paired with the own information terminal 2 via the theme reception unit 207. Identify. Specifically, the record 2080 in which the received theme is registered in the field 2081 is searched from the theme storage unit 208, and the group in which the group name is registered in the field 2082 of the searched record 2080 is specified as a participating group. . Here, if it is registered in the field 2083 of the retrieved record 2080 that an e-mail is required, an e-mail containing the target theme in the title or e-mail body is stored in the e-mail storage unit 204. Is a condition specific to the participating group. If it is registered in the field 2084 of the searched record 2080 that the electronic document file needs to be present, an electronic document file containing the target theme in the file name or document body is stored in the electronic document file storage unit 206. It is assumed that the condition is specific for the participating group.

  In addition, when the participating group specifying unit 212 specifies a participating group based on the theme received from the IP extension telephone terminal 1 paired with the own information terminal 2, the participating group specifying unit 212 refers to the belonging group storage unit 209 and The record 2090 whose group name is registered in the field 2091 is searched. If such a record 2090 can be searched (the IP extension telephone terminal 1 paired with the own information terminal 2 has already belonged to the participating group), the expiration date registered in the field 2092 of this record 2090 is set after the lapse of a predetermined period. Extend to (for example, 2 weeks after the current date and time). On the other hand, if such a record 2090 does not exist (the IP extension telephone terminal 1 paired with the own information terminal 2 does not belong to the participating group), a new record 2090 is added to the belonging group storage unit 209, and this record 2090 In the field 2091, the group name of the participating group is registered, and in the field 2092, an expiration date (for example, a date after a predetermined time elapses from the current date) is registered.

  The withdrawal group identification unit 213 refers to the belonging group storage unit 209 and identifies a group (withdrawal group) to which the IP extension telephone terminal 1 paired with the own information terminal 2 should withdraw. Specifically, it is checked whether or not there is a record 2090 whose expiration date registered in the field 2092 has passed by referring to the belonging group storage unit 209. If there is such a record 2090, the group specified by the group name registered in the field 2091 of this record 2090 is specified as the withdrawal group, and this record 2090 is deleted from the belonging group storage unit 209.

  The group registration / registration deletion request unit 214 specifies the group number of the participating group and the extension number of the IP extension telephone terminal 1 paired with the own information terminal 2 when the participating group is specified by the participating group specifying unit 212. The accompanying group registration request is generated, and this group registration request is transmitted to the SIP server 3 via the communication interface unit 201.

  Further, the group registration / registration deletion request unit 214, when the withdrawal group identification unit 213 identifies the withdrawal group, the group number of the withdrawal group and the extension number of the IP extension telephone terminal 1 paired with the own information terminal 2 A group registration deletion request with designation is generated, and this group registration deletion request is transmitted to the SIP server 3 via the communication interface unit 201.

  The group update information transmission unit 215 is stored in the group information storage unit 210 when the IP extension telephone terminal 1 paired with the own information terminal 2 does not belong to the participation group specified by the participation group specification unit 212. A record 2103 of the telephone directory data of the IP extension telephone terminal 1 paired with the own information terminal 2 is added to the participating group table 2100. The contents of this table 2100 are transmitted as participation group information to the IP extension telephone terminal 1 paired with the own information terminal 2 via the communication interface unit 201. Further, group participation terminal information including the group name and group number of the participating group and the telephone directory data of the IP extension telephone terminal 1 paired with the own information terminal 2 is generated. Then, using the participating group table 2100, each IP extension telephone terminal 1 belonging to the participating group (however, excluding the IP extension telephone terminal 1 paired with the own information terminal 2) is specified, and the communication interface unit 201. The group participation terminal information is transmitted to these IP extension telephone terminals 1 via.

  In addition, when the withdrawal group identification unit 213 identifies a withdrawal group, the group update information transmission unit 215 uses the withdrawal group table 2100 stored in the group information storage unit 210 to establish an IP pair with the own information terminal 2. The record 2103 of the telephone directory data of the extension telephone terminal 1 is deleted. Also, the withdrawal group information including the group name and group number of the withdrawal group is transmitted to the IP extension telephone terminal 1 paired with the own information terminal 2 via the communication interface unit 201. Further, group withdrawal terminal information including the group name of the withdrawal group, the group number, and the telephone directory data of the IP extension telephone terminal 1 paired with the own information terminal 2 is generated. Then, using the withdrawal group table 2100, each IP extension telephone terminal 1 belonging to this withdrawal group (however, excluding the IP extension telephone terminal 1 paired with the own information terminal 2) is specified, and the communication interface unit The group withdrawal terminal information is transmitted to these IP extension telephone terminals 1 via 201.

  10 and 11 are flowcharts for explaining the operation of the information terminal 2.

  First, when the theme receiving unit 207 receives a theme from the IP extension telephone terminal 1 paired with the own information terminal 2 via the communication interface unit 201 (YES in S300), the theme receiving unit 207 passes this to the participating group specifying unit 212. In response, the participating group identification unit 212 refers to the theme storage unit 208 and searches for a record 2080 in which the theme is registered in the field 2081 (S301). Then, the participation conditions registered in the fields 2083 and 2084 of the record 2080 are confirmed (S302).

  When only the presence of an e-mail is requested as a participation condition (“E-mail” in S302), the participation group specifying unit 212 uses the title or e-mail as the theme received from the IP extension telephone terminal 1 paired with the own information terminal 2 It is checked whether or not the e-mail included in the text is stored in the e-mail storage unit 204 (S303). If such an e-mail is stored (YES in S303), the process proceeds to S306. If such an e-mail is not stored (NO in S303), the process proceeds to S320.

  When only the presence of an electronic document file is requested as a participation condition (“electronic document file” in S302), the participation group identification unit 212 files the theme received from the IP extension telephone terminal 1 paired with the own information terminal 2 It is checked whether the electronic document file included in the name or the document text is stored in the electronic document file storage unit 206 (S304). If such an electronic document file is stored (YES in S304), the process proceeds to S306. If such an electronic document file is not stored (NO in S304), the process proceeds to S320.

  When the presence of both an electronic mail and an electronic document file is requested as a participation condition (“electronic document mail and electronic document file” in S302), the participation group specifying unit 212 makes an IP extension phone paired with its own information terminal 2 Whether the e-mail containing the theme received from the terminal 1 in the title or the mail body and the electronic document file containing the theme in the file name or the document body are stored in the e-mail storage unit 204 and the electronic document file storage unit 206, respectively. Whether or not is checked (S305). If such an e-mail and electronic document file are stored (YES in S305), the process proceeds to S306, and if not stored (NO in S305), the process proceeds to S320.

  If the existence of neither an email nor an electronic document file is requested as a participation condition (“None” in S302), the process proceeds to S306.

  In S306, the participating group specifying unit 212 specifies the group name registered in the field 2082 of the record 2080 searched from the theme storage unit 208 as the participating group. Then, the participating group identification unit 212 refers to the affiliation group storage unit 209 and checks whether or not the participating group has already been registered as an affiliation group (S307). Specifically, it is checked whether or not the record 2090 in which the participation group is registered in the field 2091 is stored in the affiliation group storage unit 209.

  When the record 2090 in which the participation group is registered in the field 2091 is stored in the affiliation group storage unit 209 (YES in S307), the participation group identification unit 212 determines the expiration date registered in the field 2092 of this record 2090. Is extended until a predetermined period has elapsed (S308). Thereafter, the process proceeds to S320.

  On the other hand, when such a record 2090 is not stored in the affiliation group storage unit 209 (NO in S307), the participating group identification unit 212 adds a new record 2090 to the affiliation group storage unit 209. The group name of the participating group is registered in the field 2091, and the expiration date is registered in the field 2092 (S309). Then, the participating group specifying unit 213 notifies the group update information transmitting unit 215 of the group name of the participating group.

  In response to this, the group update information transmission unit 215 specifies the table 2100 stored in the group information storage unit 210 in association with the group name of the participating group.
