The terminal ID of the candidate is extracted.

  Here, the destination terminal IDs “01ab”, “01ba”, and “01db” corresponding to 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 using the search key, and operates for each of the terminal IDs extracted by the terminal extraction unit 54, such as “offline”, “online (communicable)”. ”,“ Online (communicating) ”. Thereby, the operation state of each terminal 10 corresponding to the terminal IDs “01ab”, “01ba”, and “01db” can be obtained. Note that the terminal status acquisition unit 55 monitors the terminal management DB 5003, and acquires each operating status each time the operating status of the terminal 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. The destination state information includes, for example, terminal IDs “01ab”, “01ba”, “01db” as search keys used in step S27, and state information indicating the operating state of each terminal 10.

Each selection button 1311 includes information such as the terminal ID 1312 of each terminal, the total number of meetings 1313, the destination list registration state 1314, and the like. Note that a list screen 1301 of participating terminals shown in FIG. 13A is used by the display control unit 17 to register an unregistered terminal to be displayed on the display unit using the participating terminal information received by the transmitting and receiving unit 11. It is an example of a screen.

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

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

  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.

  On the confirmation screen 1302 shown in FIG. 13B, a highlighted selection button 1321 corresponding to the selected terminal ID “01bb” and a pop-up 1322 for accepting a user's confirmation operation are displayed. The user of the terminal 10A can perform an unregistered terminal registration operation 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 drawings 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 of 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 from the terminal 10A requesting registration of information on the unregistered terminal, the registration control unit 60 registers the information on the unregistered terminal in the destination list of the terminal 10A. (Registration processing) is started.

  In step S1211, the registration control unit 60 of the transmission management device 50 issues a registration confirmation request that requests an unregistered terminal (for example, the terminal 10B) to confirm registration 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 the 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 shown in FIG. Let it.

  FIG. 14 is a diagram illustrating an example of a registration confirmation screen according to the first embodiment. In the example of FIG. 14, the registration confirmation screen 1401 displays, for example, a pop-up 1413 indicating that a registration application from another terminal has been received on a screen during a meeting. The screen of the terminal 10B during the conference displays, 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 itself, and the like.

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

  In step S1214, the transmission / reception unit 11 of the terminal 10B notifies the transmission management device 50 of an acceptance notification indicating that the registration is accepted, in response to the 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 transmits a rejection notification indicating that the registration is rejected. To the transmission management device 50.

  In step S1215, upon receiving the acceptance notification from the terminal 10B, the registration control unit 60 of the transmission management device 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, a 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 shown in FIG. 8B, the terminal ID of the terminal 10B is stored in the request source terminal ID of the record in which the request source terminal ID is the terminal ID of the terminal 10A.

  According to the present embodiment, 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 receives 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 will be described in which the registration process is executed without receiving an acceptance operation by the user of the terminal 10B.

  FIG. 15 is a sequence diagram illustrating an example of a registration process of an unregistered terminal according to the second embodiment. Note that the processing of 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, the description here will focus on the differences from the first embodiment. I do.

  In step S1501, the notification unit 59 of the transmission management device 50 transmits, to the terminal 10A, participation terminal information that is information of other terminals participating in the same conference (communication session) as the terminal 10A. The participating 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 10A is registered in the destination list, and information such as the total number of conferences. For example, a destination list of another terminal 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 participating terminal list screen 1301 as shown in FIG. 13A on the display unit of the terminal 10A as in step S1207 of FIG.

  In step 1503, the operation input receiving unit 12 of the terminal 10A receives, for example, a registration introduction operation by the user from 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 this embodiment, it is assumed that the user of the terminal 10A selects a terminal whose destination list registration state is “registered” from the participating terminal list screen 1301.

  In step S1504, the display control unit 17 of the terminal 10A causes the display unit to display, for example, a registration introduction screen 1601 as shown in FIG. On the registration introduction screen 1601 shown in FIG. 16A, a pop-up list 1611 of an introduction possible list, which 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. In addition, the pop-up 1611 of the introduceable list includes one or more select buttons 1612 for selecting a terminal to be introduced from one or more introduceable terminals.

  Preferably, the selection button 1612 includes information indicating the total number of meetings between the terminal having the selected terminal ID “01ba” and the terminal having the introduceable terminal ID “01ab”. Thereby, the user of the terminal 10A can determine whether or not the selected terminal and the terminal that can be introduced have frequent meetings.

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

  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, the “destination terminal ID” that is the destination list of the terminal 10A includes the terminal IDs “01ab”, “01ba”, and “01db”.

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

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

  In step S1505, the operation input reception unit 12 of the terminal 10A receives a user's registration introduction operation from, for example, a pop-up list 1611 of an 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 registered and introduced from the selection buttons 1612 displayed on the pop-up list 1611 of the referable 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 list 1611 of the introduceable 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's confirmation operation is displayed. By selecting the “YES” button 1622 of the pop-up 1621 displayed on the confirmation screen 1602, the user of the terminal 10A can perform the registration introduction operation of the selected terminal.

  In step S1506, the transmission / reception unit 11 of the terminal 10A transmits to the transmission management device 50 the registration introduction request for requesting the terminal registration introduction processing accepted in step S1505.

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

  Note that the registration introduction process refers to, for example, registering each terminal ID in the destination list of the terminal with the terminal ID “01ba” selected in step S1503 and the terminal with the terminal ID “01ab” selected in step S1505. This is the processing to be performed. For example, the terminal ID “01ab” is registered in the destination list of the terminal having the terminal ID “01ba” by the registration introduction process, 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 device 50 updates the conference history management table 802 included in the conference history management DB 5006. For example, the registration control unit 60 deletes a record whose registration source terminal ID is “01ba” and whose unregistered ID is “01ab” from the conference history management table 802. Further, the registration control unit 60 deletes a record whose registration source terminal ID is “01ab” and whose unregistered ID is “01ba” from the conference history management table 802.

  In step S1509, the registration control unit 60 of the transmission management device 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.

  According to the above processing, also in the present embodiment, in the transmission system 1 for selecting a destination using the destination list, the user of the terminal (transmission terminal) 10 transmits the other terminal (transmission terminal) participating in the session. Can be easily registered in the destination list.

  Further, according to the present embodiment, the user of the terminal 10 can easily register another terminal participating in the session in the destination list without depending on the accepting operation of the user of the other terminal. become able to.

  In step S1702, the notification unit 59 of the transmission management device 50 selects, from among the other terminals participating in the same conference as the terminal 10A, the registration candidate terminals that are not registered in the destination list of the terminal 10A. A registration recommended terminal that recommends registration to the terminal 10A is determined.

  For example, when the number of registration candidate terminals is equal to or less than a predetermined number (for example, two), the notification unit 59 determines each of the registration candidate terminals as a registration recommended terminal. On the other hand, when the number of registration candidate terminals exceeds a predetermined number (for example, two), the notification unit 59 extracts a predetermined number of registration candidate terminals from the registration candidate terminals in descending order of priority, Decide on a terminal recommended for registration.

  In step S1703, the notification unit 59 of the transmission management device 50 notifies the terminal 10A of the information on the registration recommended terminal determined in step S1702.

  In step S1704, when the transmission / reception unit 11 of the terminal 10A receives the registration recommendation terminal information notified from the transmission management device 50, the display control unit 17 uses the received information, for example, as shown in FIG. A registration recommendation screen as shown is displayed on the display unit.
