Candidate terminal IDs are extracted.

  Here, “01ab”, “01ba”, and “01db”, which are destination terminal IDs for the terminal ID “01aa” of the terminal 10aa, are extracted.

  In step S27, the terminal status acquisition unit 55 of the transmission management device 50 uses the terminal IDs “01ab”, “01ba”, and “01db” of the destination terminal candidates extracted by the terminal extraction unit 54 as search keys. The terminal status acquisition unit 55 searches the terminal management table 703 included in the terminal management DB 5003 by using the search key, and the operation status “offline” and “online (communicable)” for each terminal ID extracted by the terminal extraction unit 54. ”And“ Online (during communication) ”are read out. Thereby, the operating state of each terminal 10 corresponding to the terminal IDs “01ab”, “01ba”, and “01db” can be acquired. The terminal state acquisition unit 55 monitors the terminal management DB 5003 and acquires each operation state every time the terminal operation state changes.

  In step S28, the transmission / reception unit 51 of the transmission management device 50 transmits the destination state information to the terminal 10aa via the transmission network 2. This destination status information includes, for example, terminal IDs “01ab”, “01ba”, “01db” as search keys used in step S27, status information indicating the operating status of each terminal 10, and the like.

  Thereby, the terminal 10aa can grasp the current operation states “offline”, “online (communication possible)”, and “online (during communication)” of the terminals 10ab, 10ba, and 10db that are candidates for the destination terminal. it can.

  In step S29, the terminal extraction unit 54 of the transmission management device 50 uses the terminal ID “01aa” of the terminal 10aa that requested the login as a search key.

  In step S30, the state management unit 53 of the transmission management device 50 uses the terminal ID “01aa” of the terminal 10aa that requested the login as a search key. The state management unit 53 searches the terminal management table 703 included in the terminal management DB 5003 using the search key, and acquires the operating state “online (communicable)” of the terminal 10aa that requested the login.

  In steps S31-1 and S31-2, the transmission / reception unit 51 of the transmission management device 50 has, for example, the terminal management table 703 shown in FIG. The terminal ID is extracted. In addition, the transmission / reception unit 51 transmits the terminal ID of the request source terminal (terminal 10aa) and the operation state “online (communicable)” to the terminal 10 (for example, terminal 10ba, terminal 10db) corresponding to the specified terminal ID. Send status information including

  When transmitting the status information to the terminals 10ba and 10db, the transmission / reception unit 51 refers to the IP address of each terminal managed in the terminal management table 703 based on the terminal IDs “01ba” and “01db”. .

  As a result, the terminal 10db and 10ba that can specify and transmit the terminal 10aa that has requested login as the destination terminal are assigned the terminal ID “01aa” and the operation status “online (during communication)” of the terminal 10aa that has requested login. I can tell you.

  When step S28 of the preparatory stage operation is completed, the display control unit 17 of the terminal 10aa determines from the information of the destination list displayed on the display 120 that the terminal participating in the video conference, that is, the operating state is “online”. The information on the terminal 10db that is “in communication” or “online (communication available)” may be highlighted on the display 120. Thereby, the user can recognize the terminal 10 participating in the video conference or the terminal 10 that can participate.

In this case, it is desirable that the notification unit 59 of the transmission management device 50 notifies the terminal 10 by including the priority information of the conference history management table 802 in the participating terminal information.

  In step S1207, when the transmission / reception unit 11 of the terminal 10A receives the participating terminal information notified from the transmission management device 50, the display control unit 17 uses the received participating terminal information, for example, FIG. A list screen of participating terminals as shown in FIG.

  A list screen 1301 of participating terminals shown in FIG. 13A displays a plurality of selection buttons 1311 for selecting participating terminals that are other terminals participating in the same conference as the terminal 10A. Each selection button 1311 includes information such as the terminal ID 1312 of each terminal, the cumulative conference count 1313, and the destination list registration state 1314. Note that the participation terminal list screen 1301 illustrated in FIG. 13A is a display for the display control unit 17 to register an unregistered terminal to be displayed on the display unit using the participation terminal information received by the transmission / reception unit 11. It is an example of a screen.

  In step S1208, the operation input receiving unit 12 of the terminal 10A receives a user registration operation from the participating terminal list screen 1301 illustrated in FIG.

  For example, the user of the terminal 10A corresponds to a terminal that is desired to be registered in the destination list from among the terminals whose destination list registration status is “unregistered” displayed on the participating terminal list screen 1301 shown in FIG. The selection button 1311 to be selected is selected.

  For example, when the user of the terminal 10A selects the selection button 1311 corresponding to the terminal with the terminal ID “01bb” from the participating terminal list screen 1301 shown in FIG. A confirmation screen 1302 as shown in b) is displayed on the display unit.

  In the confirmation screen 1302 shown in FIG. 13B, a selection button 1321 that is highlighted and corresponding to the selected terminal ID “01bb” and a pop-up 1322 that accepts a user confirmation operation are displayed. The user of the terminal 10 </ b> A can perform the registration operation of the unregistered terminal by selecting the “YES” button 1323 of the pop-up 1322 displayed on the confirmation screen 1302.

  In FIG. 13B, “terminal (01bb)” represents the terminal 10 whose terminal ID is “01bb”. The same applies to other figures thereafter.

  In step S1209, the transmission / reception unit 11 of the terminal 10A transmits, to the transmission management device 50, a registration request for requesting registration of the information on the unregistered terminal received in step S1208 in the destination list.

  In step S1210, when the registration control unit 60 of the transmission management device 50 receives a registration request for requesting registration of information on an unregistered terminal from the terminal 10A, control for registering information on the unregistered terminal in the destination list of the terminal 10A. (Registration process) starts.

  In step S1211, the registration control unit 60 of the transmission management device 50 issues a registration confirmation request for requesting confirmation of registration to an unregistered terminal (for example, the terminal 10B) based on the terminal ID of the unregistered terminal included in the registration request. Send.

  In step S1212, when the transmission / reception unit 11 of the terminal 10B receives a registration confirmation request from the transmission management device 50, the display control unit 17 of the terminal 10B displays, for example, a registration confirmation screen as illustrated in FIG. Let

  FIG. 14 is a diagram illustrating an example of a registration confirmation screen according to the first embodiment. In the example of FIG. 14, on the registration confirmation screen 1401, for example, a pop-up 1413 indicating that a registration application from another terminal has been received is displayed on the screen during the meeting. Note that, for example, conference images 1411a to 1411c received from other terminals participating in the conference, a conference image 1412 of the terminal 10B that is the terminal 10B, and the like are displayed on the screen during the conference of the terminal 10B.

  The user of the terminal 10B can perform an acceptance operation for accepting registration by selecting a “YES” button 1414 from a pop-up 1413 displayed on the registration confirmation screen 1401.

  In step S <b> 1214, the transmission / reception unit 11 of the terminal 10 </ b> B notifies the transmission management apparatus 50 of an acceptance notification indicating that the registration is accepted in response to an acceptance operation by the user.

  For example, when the user of the terminal 10B selects the “NO” button from the pop-up 1413 displayed on the registration confirmation screen 1401, the transmission / reception unit 11 of the terminal 10B rejects the registration. To the transmission management device 50.

  In step S1215, when receiving the acceptance notification from the terminal 10B, the registration control unit 60 of the transmission management apparatus 50 updates the conference history management table 802 included in the conference history management DB 5006. For example, in the conference history management table 802 shown in FIG. 8B, the record in which the registration source terminal ID is the terminal ID of the terminal 10A and the unregistered terminal ID is the terminal ID of the terminal 10B is deleted.

  In step S1216, the registration control unit 60 of the transmission management device 50 registers the terminal ID of the terminal 10B in the destination list of the terminal 10A. For example, in the destination list management table 702 illustrated in FIG. 8B, the terminal ID of the terminal 10B is stored in the request source terminal ID of the record whose request source terminal ID is the terminal ID of the terminal 10A.

  Through the above processing, according to the present embodiment, in the transmission system 1 that selects a destination using the destination list, the user of the terminal (transmission terminal) 10 is joined to another terminal (transmission terminal) participating in the session. Can be easily registered in the destination list.

[Second Embodiment]
In the first embodiment, when the user of the terminal 10A registers the terminal 10B that is not registered in the destination list among the terminals participating in the conference during the conference, the terminal 10B accepts the terminal 10B. Registration to the destination list was performed based on the operation.

  In the second embodiment, an example in which registration processing is executed without receiving an acceptance operation by the user of the terminal 10B will be described.

  FIG. 15 is a sequence diagram illustrating an example of registration processing of an unregistered terminal according to the second embodiment. Note that the processing in steps S1201 to S1205 in FIG. 15 is the same as the registration processing of the unregistered terminal according to the first embodiment shown in FIG. 12, and therefore, here, the description will focus on differences from the first embodiment. I do.

  In step S1501, the notification unit 59 of the transmission management device 50 transmits participation terminal information, which is information on other terminals participating in the same conference (communication session) as the terminal 10A, to the terminal 10A. The participation terminal information includes, for example, terminal IDs of other terminals participating in the same conference as the terminal 10A, information indicating whether or not the terminal is registered in the destination list of the terminal 10A, and information such as the total number of meetings. Thus, a destination list of other terminals participating in the same conference as the terminal 10A is included.

  In step S1502, the display control unit 17 of the terminal 10A displays a list screen 1301 of participating terminals as illustrated in FIG. 13A on the display unit of the terminal 10A, as in step S1207 of FIG.

  In step 1503, the operation input accepting unit 12 of the terminal 10A accepts a registration introduction operation by the user from, for example, the participating terminal list screen 1301 shown in FIG. For example, in the “registration operation” of the first embodiment, the user of the terminal 10A selects a terminal whose destination list registration state is “unregistered” from the participating terminal list screen 1301. On the other hand, in the “registration introduction operation” of the present embodiment, it is assumed that the user of the terminal 10A selects a terminal whose destination list registration state is “registration” from the participating terminal list screen 1301.

  In step S1504, the display control unit 17 of the terminal 10A displays, for example, a registration introduction screen 1601 as illustrated in FIG. 16A on the display unit in response to reception of the registration introduction operation. On the registration introduction screen 1601 shown in FIG. 16A, a pop-up 1611 of an introduceable list that is a list of terminals that can be introduced to the terminal selected in step S1503 (for example, the terminal with the terminal ID “01ba”) is displayed. ing. Further, the pop-up 1611 of the introduceable list includes one or more selection buttons 1612 for selecting a terminal to be introduced from one or more introduceable terminals.

  Preferably, the selection button 1612 includes information indicating the cumulative number of conferences between the selected terminal ID “01ba” and the terminal ID “01ab” that can be introduced. Thereby, the user of the terminal 10A can determine whether the selected terminal and the terminal that can be introduced frequently hold meetings.

  The selected terminal, for example, the terminal that can be introduced to the terminal having the terminal ID “01ba” is the terminal that has the terminal ID “01ba” among the terminals registered in the destination list of the terminal 10A. Terminals that are not registered in the list are extracted.

  For example, in the destination list management table 702 shown in FIG. 7B, it is assumed that the terminal ID of the terminal 10A is “01aa”. In this case, terminal IDs “01ab”, “01ba”, and “01db” are included in the “destination terminal ID” that is the destination list of the terminal 10A.

  Here, assuming that the selected terminal ID is “01ba”, the “destination terminal ID” that is the destination list of the terminal ID “01ab” does not include the selected terminal ID “01ba”. On the other hand, the selected terminal ID “01ba” is included in the “destination terminal ID” that is the destination list of the terminal ID “01db”.

  In this case, the terminal that can be introduced by the terminal 10A to the terminal having the selected terminal ID “01ba” is the terminal ID “01ab”.

  In step S1505, the operation input accepting unit 12 of the terminal 10A accepts a user's registration introduction operation from, for example, a pop-up 1611 of the introduction possible list on the registration introduction screen 1601 shown in FIG.

  For example, the user of the terminal 10A selects the selection button 1612 corresponding to the terminal to be introduced from the selection buttons 1612 displayed in the pop-up 1611 of the introduction possible list shown in FIG. For example, when the user of the terminal 10A selects the selection button 1612 corresponding to the terminal with the terminal ID “01ab” from the pop-up 1611 of the referable list shown in FIG. A confirmation screen 1602 as shown in b) is displayed on the display unit.

  On the confirmation screen 1602 shown in FIG. 16B, a pop-up 1621 for accepting a user confirmation operation is displayed. The user of the terminal 10 </ b> A can perform the registration introduction operation of the selected terminal by selecting the “YES” button 1622 of the pop-up 1621 displayed on the confirmation screen 1602.

  In step S <b> 1506, the transmission / reception unit 11 of the terminal 10 </ b> A transmits a registration introduction request for requesting the registration introduction process of the terminal received in step S <b> 1505 to the transmission management apparatus 50.

  In step S1507, upon receiving a registration introduction request from the terminal 10A, the registration control unit 60 of the transmission management device 50 starts a terminal registration introduction process.

  For example, the registration introduction process registers each other's terminal IDs in the destination list of the terminal having the terminal ID “01ba” selected in step S1503 and the terminal having the terminal ID “01ab” selected in step S1505. It is processing to do. For example, in the registration introduction process, the terminal ID “01ab” is registered in the destination list of the terminal having the terminal ID “01ba”, and the terminal ID “01ba” is registered in the destination list of the terminal having the terminal ID “01ab”. be registered.

  In step S1508, the registration control unit 60 of the transmission management apparatus 50 updates the conference history management table 802 included in the conference history management DB 5006. For example, the registration control unit 60 deletes the record having the registration source terminal ID “01ba” and the unregistered ID “01ab” from the conference history management table 802. Further, the registration control unit 60 deletes the record having the registration source terminal ID “01ab” and the unregistered ID “01ba” from the conference history management table 802.

  In step S1509, the registration control unit 60 of the transmission management apparatus 50 registers the terminal ID “01ab” in the destination list of the terminal having the terminal ID “01ba”, and registers the terminal ID “01ab” in the destination list of the terminal having the terminal ID “01ab”. The terminal ID “01ba” is registered.

  Through the above processing, also in the present embodiment, in the transmission system 1 that selects a destination using the destination list, the user of the terminal (transmission terminal) 10 connects other terminals (transmission terminals) participating in the session. , Can be easily registered in the destination list.

  In addition, according to the present embodiment, the user of the terminal 10 can easily register other terminals participating in the session in the destination list without depending on the acceptance operation of the user of the other terminals. become able to.
