The conference service device 2 performs simultaneous communication connection of the participating terminals 1 in each communication terminal 1 via the switching node 3 in accordance with an instruction from the connection processing unit 6 of the switching node 3 which will be described later. Further, the exchange node 3 performs an exchange process of normal communication between the respective communication terminals 1,
The connection processing is performed in the simultaneous communication conference.
Therefore, as a functional unit for executing the connection processing in the simultaneous communication conference, the exchange node 3 includes the terminal management unit (terminal management unit) 4, the number translation unit (number translation unit) 5, the connection processing unit (connection processing unit). ) 6 is provided.

Here, the terminal management unit 4 registers and manages the chairman qualification terminal and the chairman terminal.
As shown in FIG. 3, a chair qualification registration control unit 41 and a chair qualification terminal check unit 42 are provided. The chair qualification registration control unit 41 registers or updates the chair qualification terminal among the plurality of communication terminals 1 in advance by operating the communication terminal 1 / maintenance staff command. Therefore, the chair qualification registration control unit 41 is configured to perform the following processing. That is, the chair qualification registration control unit 41 indexes the subscriber data of the communication terminal 1 instructed to register as the chair qualification terminal at the time of command input or update from the terminal (step A1 in FIG. 3), The qualification display of the data is updated (step A2 in FIG. 3), and the update result is notified to the communication terminal 1 / maintenance person (step A3 in FIG. 3). When indexing the subscriber data, the subscriber data is read out via the number translation unit 5. Further, the chair qualification registration control unit 41 is adapted to collectively register the qualification display together with other information at the initial subscriber data registration.

Also, when registering the chairman qualified terminal, the terminal management unit 4 registers the chairman qualified terminal so that the convening method of all the participating terminals 1 and the additional terminal 1 adopts the batch connection processing method. Has become. Therefore, the chair qualification terminal, when making a request for convening a meeting, simultaneously designates the members of the multipoint address to be convened in the meeting by collectively designating by the group address specification.
Further, this collective designation information is provided with additional information in addition to the group address, and this additional information is difference information (information such as addition / deletion) of meeting convening members with respect to the group address.

The chair qualification terminal check unit 42
The conference connection request is permitted only when a subscriber service request call (connection request at the time of convening a conference) is sent from a pre-registered chairman qualification terminal. At the same time, only the chairman qualified terminal is recognized as the chairman terminal, and the connection processing unit 6 is notified that the communication terminal 1 is the chairman terminal. Also, the chair qualification terminal check unit 42
Is designed to perform connection control processing for additional terminals during a conference.

Therefore, the chair qualification terminal check unit 42
Is configured to perform the processing shown in FIGS. That is, the subscriber data of the communication terminal 1 which has made a connection request at the time of convening a conference is read out via the number translation unit 5 (step B1 in FIG. 3), and the presence or absence of the chairman qualification display is checked from the subscriber data (FIG. Step B2 of 3).

When the chairperson qualification is displayed in the subscriber data, the "OK" route in step B2 of FIG. 3 is taken to indicate that the communication terminal 1 is the chairperson terminal to the connection processing unit 6. Notification (step B in FIG. 3)
3), notify the chairman terminal / maintenance person that this communication terminal 1 is authorized as the chairman terminal (step B4 in FIG. 3).
It is like this. If the chairperson qualification is not displayed in the subscriber data, the “NO” route in step B2 of FIG. 3 is taken to indicate that the communication terminal 1 was not certified as the chairman terminal. The maintenance person is notified (step B4 in FIG. 3).

Further, when the chairman qualified terminal check unit 42 accepts a conference service call at the time of additional call during the conference, it reads the subscriber data of the communication terminal 1 via the number translation unit 5. (Step B'1 in FIG. 4). Then, it is determined whether or not the communication terminal 1 is a chairman qualified terminal (step B'2 in FIG. 4), and the fact is notified to the chairman terminal / maintenance person (FIG. 4).
Step B'3).

By the way, when a request for convening a conference is made from the chairman terminal by batch designation by group address designation, the number translation unit 5 determines a multipoint address based on the group address and additional information included in the request. It is a thing. For this reason, the number translation unit 5 is composed of a number translation execution unit 51 and a group address management table 52, as shown in FIG. The number translation executing unit 51 determines a multipoint address from the group address, the additional information, and the information registered in the group address management table 52.

Therefore, the number translation executing section 51 is configured to perform the processing shown in FIG. That is,
The number translation executing unit 51 indexes the corresponding address expansion table registered in advance in the group address management table 52 according to "group address + difference information" passed as transmission information from the chairman terminal ( Step C1 of FIG. 5). Then, the difference address is corrected from each address of the members of the designated group to determine the ground address (step C2 in FIG. 5), and the determined address information is passed to the connection processing unit 6. (Step C3 in FIG. 5).

Further, the number translation executing section 51 is connected to the communication terminal 1 /
When the maintenance person inquires about the registration status of the group address, the designated group address information is taken out (step D1 in FIG. 5), the group address is expanded (step D2 in FIG. 5), and the registration status is communicated. Terminal 1
/ It notifies the maintenance person (step D3 in FIG. 5).

Alternatively, when the communication terminal 1 / maintenance person makes a request to update the group address, the number translation executing section 51 takes out the specified group address information (step D1 in FIG. 5) and sends it. The additional information and the like are updated (step D2 in FIG. 5), and the result is notified to the communication terminal 1 / maintenance person (step D3 in FIG. 5).

Then, the group address management table 5
As indicated by its name, reference numeral 2 is a table for registering the addresses of members who are invited to the conference in group units and managing the group addresses. By the way, the connection processing unit (multipoint connection control unit) 6 performs the connection with all the participating terminals 1 via the conference service device 2 in the following manner. That is, the connection processing unit 6 executes the connection process for the participating terminal 1 based on the multipoint address determined by the number translation unit 5.

When the connection completion waiting time for collective connection processing elapses, the connection processing unit 6 notifies the chairman terminal of the connection completion, and holds the conference connection service by the currently connected call. It is like this. In addition, the connection processing unit 6 is configured to continue the connection processing for the remaining connected calls that have not yet participated in the conference and the halfway participation calls even after the conference connection service is held. Further, when the remaining connected calls are completed, they are sequentially added to the conference connection, and the fact is notified to the chair terminal or the maintenance person. Further, the connection processing unit 6 stops the connection of the remaining calls when the connection completion waiting time for the ongoing call elapses.

Further, the connection processing unit 6 determines the connection completion waiting time of all participating terminals 1 and the connection completion waiting time for ongoing calls in the collective connection processing method before the conference is held and after the connection processing is started. It is designed to be updated at the request of the chairman terminal / maintenance person. Furthermore, the connection processing unit 6
When a connection release request is received from the chair terminal in the connection release at the end of the conference, the connection is released by all the terminals 1 participating in the conference and the conference is terminated. When receiving the connection release request from the terminal 1, only the connection of the requesting terminal 1 is released.

For this reason, the connection processing unit 6 comprises a multipoint connection control request unit 61, a connection result control unit 62, a continuous connection result control unit 63, and a disconnection control unit 64. Here, the multipoint connection control request unit 61 performs timed monitoring control of the connection completion waiting time of all participating terminals 1 of the collective connection process in the multipoint connection control. Therefore, the process shown in FIG. 6 is performed. Is configured to do. That is,
Upon receiving the expanded address from the number translation unit 5 (step E1 in FIG. 6), the multipoint connection control request unit 61 checks whether or not there is timing designation in the outgoing information from the chairman terminal (FIG. 6). Step E2).

When there is a timed request from the chairman's terminal, FIG.
The “Yes” route of step E2 is taken, the value is taken as overall timing (step E3 in FIG. 6), and this value is set as it is (step E5 in FIG. 6). If a new timing designated time is sent from the chairman terminal / maintenance person after the connection processing is started, the timing is updated as an overall timing value.

If there is no time request from the chairman terminal, the "none" route of step E2 of FIG. 6 is taken and a variable value according to the number of connected ground points is set as overall timing (step E4 of FIG. 6). (Step E5 in FIG. 6). After the overall timing is set, the conference service device 2 and the exchange node 3 are requested to connect the communication terminal 1 and the conference service device 2 corresponding to the expanded address (step E6 in FIG. 6). .

The variable value is calculated by the following equation. Basic value + (total number of communication terminals 1 invited to conference × time T) However, the basic value is a value registered in advance, and the time T is the time assigned to one communication terminal 1. still,
The multipoint connection control request unit 61 also sets the connection completion waiting time for the ongoing call in the same manner as above.

The connection result control unit 62 performs a connection process at the end of the connection, and therefore is configured to perform the process shown in FIG. That is, the connection result control unit 62 receives the connection result of each communication terminal 1 by the exchange process of the exchange node 3 and accumulates the information (step F1 in FIG. 7). On this occasion,
Regarding the connection control information of all the participating terminals 1, the result is notified only to the completed portion or the incomplete portion, or both information is notified to the chairperson terminal / maintenance person (step F4 in FIG. 7).

When the connection of all the communication terminals 1 is completed within the connection completion waiting time of all the participating terminals 1 in the collective connection processing method, the "complete" route of step F2 of FIG. 7 is taken to release the overall timing. Then (step F3 in FIG. 7), a connection result notification indicating the completion of the connection is notified to the chairperson terminal / maintenance person (step F4 in FIG. 7).

Further, the connection result control unit 62, when the first timed monitoring is activated when executing the multipoint connection control, that is,
When the control completion waiting time for collective connection control is over (TO (time.
over)), a continuous connection processing in progress display is set, and that effect is notified to the continuous connection result control unit 63, and the caller terminal (chairman terminal) 1 is once notified of completion of call connection. For ongoing calls, the connection operation is continued (steps G2 and G in FIG. 7).
3).

Further, the continuous connection result control unit 63 controls the ongoing call, and therefore is configured to perform the processing shown in FIGS. That is, when the continuous call is connected, the continuous connection result control unit 63 receives the information from the connection result control unit 62, takes the dotted line route of step F1 of FIG. 7, and connects the connected communication terminal. No. 1 is also incorporated in the conference service by notifying the chairman terminal / maintenance person by a notification signal (Fig. 7).
Step H1).

Further, the continuous connection result control unit 63 is adapted to carry out batch timed monitoring in the same manner as the first call connection request. That is, the connection result of the ongoing call by the exchange processing of the exchange node 3 is received and the information is accumulated (step J1 in FIG. 8). At this time, regarding the connection control information of the communication terminal 1 which is continuing, the result is notified to the chairperson terminal / maintenance person only for the completed portion or only for the incomplete portion (FIG. 8).
Step J4).

When all the connection of the ongoing call is completed within the connection completion waiting time for the ongoing call, the "complete" route of step J2 in FIG. 8 is taken to release the overall timing. (Step J3 in FIG. 8), the connection result notification indicating the completion of the connection is notified to the chairperson terminal / maintenance person (Step J4 in FIG. 8). Further, the continuous connection result control unit 63 sets the continuous connection processing in progress display when the control completion waiting time for the ongoing call is over (TO (time.over) in step K1 of FIG. 8). (Step K2 in FIG. 8), the connection completion notification is sent to the calling terminal 1 (Step K3 in FIG. 8).
The notice of connection completion to the chairman terminal / maintenance person is given by a notification signal different from the call connection completion.

The disconnection control unit 64 controls the call disconnection process, and is therefore configured to perform the process shown in FIG. That is, when the disconnection request is sent, the disconnection control unit 64 checks whether the requester is the chairperson terminal or the general participation terminal 1 (step L1 in FIG. 9). Then, if the disconnection request sent is from the general participation terminal (participation terminal in step L1 of FIG. 9), the disconnection request of the communication terminal 1 is recognized and only the connection of this terminal 1 is released. (Step L2 in FIG. 9). When the disconnection request from the general participation terminal is recognized, the fact is notified that the current connection result information (F1 of the connection result control unit 62 of FIG. 7 and FIG.
The continuous connection result control unit 63 is updated to J1) (step L3 in FIG. 9) to notify the chairman terminal / maintenance person of the disconnection completion notification (step L4 in FIG. 9).

If the disconnect request sent is from the chairman terminal (“chairman terminal” route in step L1 of FIG. 9), the connected call information is retrieved (step L of FIG. 9).
5) Based on the connection call information, the calls of all terminals 1 participating in the conference are released (step L in FIG. 9).
6). Then, when disconnection of all communication terminals 1 is completed, a disconnection completion notification is sent to the chairman terminal / maintenance person (step L7 in FIG. 9).

With this arrangement, the exchange node 3 is
Simultaneous communication is performed by connecting a plurality of communication terminals 1 and the conference service device 2. That is, the exchange node 3 is the chairman terminal /
According to the instruction from the maintenance person, by the terminal management unit 4,
The chairman qualified terminal is registered in advance from the plurality of communication terminals 1. At the same time, the exchange node 3 sets, in the connection processing unit 6, the connection completion waiting time of all the participating terminals 1 in the collective connection processing method instructed by the communication terminal 1 or the maintenance person.

Then, the terminal management unit 4 only when the registered chairman qualification terminal issues a connection request at the time of convening a meeting.
Accepting the conference connection request, the chairman qualified terminal is recognized as the chairman terminal. At this time, if a meeting invitation request is made from the chairman terminal by batch designation by group address designation, the number translation unit 5 determines the multipoint address based on the group address and the difference information included in the request. In other words, the number translation unit 5 considers the difference information for each communication terminal information forming the group.

Then, the connection processing unit 6 executes the connection with each participating terminal 1 via the conference service device 2 as described below. That is, the connection processing unit 6 executes the connection process for the participating terminal 1 based on the multipoint address determined by the number translation unit 5. Then, when the connection completion waiting time for the collective connection processing elapses, the connection processing unit 6 notifies the chairman terminal of the connection completion, and holds the conference connection service by the currently connected call.

Further, even after the conference connection service is held, the connection processing unit 6 continues the connection processing for the remaining connected call and the halfway participation call. Then, when the remaining connected calls are completed, at that time, they are sequentially added to the conference connection, and the fact is notified to the chairperson terminal or the maintenance person. After that, when the connection completion waiting time for the ongoing call elapses, the connection processing unit 6
Abandon the remaining call connections.

After the connection processing is started, the chairperson terminal or the maintenance person changes the connection completion waiting time of all participating terminals 1 in the collective connection processing method set before the conference or the connection completion waiting time of the ongoing call. When instructed,
The connection processing unit 6 updates the connection completion waiting time of all participating terminals 1 and the connection completion waiting time for ongoing calls in the collective connection processing method.

As a result, from this point, the connection completion waiting times for the connection processing of all participating terminals 1 in the batch connection processing method currently in progress and the connection processing for ongoing calls are newly updated. It will be changed to the one you did. Further, in connection release at the end of the conference, when the chair terminal sends a connection release request to the connection processing unit 6, the connection processing unit 6 having received this request releases the connection of all the terminals 1 participating in the conference. Alternatively, when a participating terminal 1 other than the chairperson terminal sends a connection release request to the connection processing unit 6, only the connection of the requesting terminal 1 is released by the connection processing unit 6 that has received this request.

By providing the exchange node 3 with the terminal management unit 4, the number translation unit 5, and the connection processing unit 6 as described above, addresses can be input all at once, and call connection can be controlled in a short time. I can do it. At the same time, the load on the communication terminal (chairperson's terminal) can be reduced, and its handling becomes simple. Then, since the chairperson terminal can grasp all the connection destination information, the security can be improved and the smooth remote conference can be promoted.

Further, the connection completion waiting time of all participating terminals 1 and the update of the connection completion waiting time for ongoing calls in the collective connection processing method can be freely changed before the conference is held or after the connection processing is started. , The timing of holding a conference can be set according to the situation, and the conference can be more smoothly proceeded. Further, the communication terminal 1 desiring a disconnection request can freely leave the conference without affecting the other conference participation terminals 1, and at the end of the conference, the chair terminal simply requests the switching node 3 to disconnect. Since the collective disconnection process is performed, the operation of each communication terminal 1 can be simplified.
