Abstract

PURPOSE:To improve the utilizing efficiency of a line port of a center node by applying control such as provision of a representative number, registration and erasure dynamically for each sponsored conference with respect to a multi- point conference unit of the center node to which a terminal equipment is going to be connected. CONSTITUTION:When a request of desiring the start of a conference from a time T at three points of terminal equipments A, B and C is inputted to a conference reservation system, a representative number control means 103 selects three ports provided to a center node, gives one representative number and registers sets of each line number of the 3 ports corresponding to the representative number to a representative number database 105. The terminal equipments A, B, C call the representative number to an exchange 104 at a conference start time T. The exchange 104 discriminates the information of the representative number database 105 as ports of line numbers 1, 2, 3 of the center node, calls the center node to apply connection control.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a representative number control system for connecting a plurality of terminals to a multipoint conference unit.

(Prior Art) An example of a conventional multipoint conference connection control system will be described with reference to FIG. In the figure, 600 is the center node, which has two multipoint conference units 60L 602, and 1 as the line number.
, 2, 3, 4, 5, 6, 7, and 8. The exchange 603 is also equipped with a representative number database 604. A line port is fixedly assigned to each multipoint conference unit 601 and 602. Figure 6 shows line numbers 1, 2,
The three ports of 3 are fixedly connected to the multipoint conference unit 601.
The diagram shows that five ports with line numbers 4, 5, 6, 7, and 8 are fixedly assigned to the multipoint conference unit 602. Furthermore, line number 1
, 2, and 3 are assigned a representative number IO, and five sets of line numbers 4, 5, 6, 7, and 8 are assigned a representative number 20. This information is stored in the representative number database 6 as shown in Figure 7.
04 and cannot be rewritten.

Here, as an example, a connection method when a three-point conference is held between terminals A, B, and C using the multi-point conference unit 60J will be shown. It is assumed that the representative number 10 representing the line numbers of the three boats connected to this multipoint conference unit 601 has been notified in advance to each terminal A, B, and C by means such as a conference notification. When the conference start time arrives, terminals A, B, and C each make a call using number 10 to be connected. When the exchange 603 receives the number 10, it determines from the representative number database that the representative number indicates each port of line numbers 1, 2, and 3 of the center node, and communicates between each terminal A, B, (; and those ports). The line is connected.In this case, as in the typical number processing in an exchange, an empty port is searched and connected, so the combination of each terminal and boat is arbitrary.

(The problem to be solved by the invention is that in the conventional connection control system for multipoint conferences, it is not possible to rewrite the representative number database of the exchange. had to be fixed and registered in the representative number database.Therefore, the number of terminals that could be accommodated by the corresponding multipoint conference unit was limited to the number of boats initially determined by the representative number. For example, the multipoint conference unit 6 shown in FIG.
01 is a unit with a maximum of 3 points, and 602 is a canine dog 5
It is a unit up to a point. For this reason, for example, when conducting a four-point conference, the multipoint conference unit 1-602 must be used, and one port 1-602 becomes unused and wasted.

In this example, the 8 ports are fixedly divided into 3 ports and 5 ports, so it is impossible to hold two 4-point conferences at the same time.

(Means for Solving the Problem) According to the representative number control method for multipoint conference connection according to the present invention, at least one multipoint conference unit is provided in the center node and transmits and receives information between a plurality of terminals. This is a method in which the plurality of terminals are connected via a switch.
Said multi-point conference. A representative number control system for multipoint conference connections is proposed in which each terminal makes a call using a line representative number that uniquely represents a network as an identifier.

Further, the representative number control means provided in the center/one node connects the multipoint conference unit from M ports provided in the center node to which line numbers are fixedly assigned in advance prior to the conference. N (N<M) boats are selected and connected to the multipoint conference unit I in the center node, and the N? A representative number that uniquely represents each line number of the boat is assigned, and a set of the four-line number of the boat corresponding to the representative number of the boat is registered in the representative number database provided by the exchange and Co., and the said exchange It is characterized in that line connection control is performed according to jl' aa representative number database information.

Further, after the meeting is over, the set of the registered representative number and the corresponding line number is deleted from the representative number database.

(Operation) In the representative number control method in multipoint conference connection of the present invention, {
J. Prior to the conference call, select as many boats as the number of points 7 and connect them to the multipoint conference unit, and provide a representative number representing the line number of those boats 1 to each terminal. The registered representative number 8 will be deleted when the meeting is over.

(Embodiment) FIG. 1 is a functional block diagram showing the system configuration of an embodiment of the representative number control method in multipoint conference connection according to the present invention. The center node 100 has line numbers 1, 2,
8 ports having ports 3, 4, 5, 6, 7, and 8, multipoint conference units 101 and 102 that connect a plurality of these ports to exchange information between terminals, and are used prior to a conference. It consists of a representative number control means 103 that selects ports, connects them to a multipoint communication unit, assigns a representative number, and registers/deletes the ports in a representative number database 105 provided in the exchange 104. Ru.

In the following, as an example, a connection method between three points of terminals A, B, and C will be explained first. First, it is assumed that a conference reservation system is generally used to set up a conference.

In other words, the person setting up the meeting must specify in advance the number of participants or locations,
Conference reservation information such as start time is registered in the conference reservation system. Here, as an example, a request from terminal A to hold a conference at three locations with terminals B and C starting at time T is input into the conference reservation system. This embodiment does not particularly limit the implementation structure of such a conference reservation system.

When the representative number control means 103 receives this information from the conference reservation system, it performs the following control. First, since the number of terminals to be connected to the multipoint conference unit is three, three are selected from the boats provided in the center node.

Now assume that these are ports with line numbers 1, 2, and 3, respectively. Next, the representative number control means 103 assigns one representative number to these three boats. Let's call this number 10 now. Further, the representative number control means 103 allocates these three boats to the multipoint conference unit 101 as connection ports, that is, the representative number 10 is assigned to the multipoint conference unit 101. Next, the representative number control stage 103 registers in the representative number database 105 the set of line numbers of the three ports corresponding to this representative number 10. This situation is shown in FIG.

FIG. 2(a) shows the contents of the representative number database when no conference is set, that is, when nothing is registered. Next, FIG. 2(b) shows the contents of the representative number database when the representative number control means registers a set of three boats corresponding to the representative number 10. The conference reservation information and representative number are sent to each terminal A. B, C
will be sent in advance to the following users. Although a mail service is generally used for this method, this embodiment does not particularly limit the implementation structure of such a mail system. After the above control, the exchange connects ifi! in the sequence shown in FIG. 3(a) as an example. Perform I control. That is, at the conference start time T, each terminal A, B, and C calls the exchange 104 using the representative number 10 and L7. In the exchange 104, based on the information in the representative number database 105, this representative number 10 is assigned to the center node's line numbers 1 and 2.
It determines that this indicates port No. and No. 3, calls the center node, and performs connection control. As a result, the terminal and the multipoint conference unit are connected as shown in FIG. 3(b), and a conversation can be performed. In this case, the combination of each terminal and port can be arbitrary as the vacant boat is searched for as seen in the representative number processing in the exchange, but as shown in Figure 3(b)
So terminal A and line number 1 boat, terminal B and line number 2
This shows an example in which a port with terminal C and a port with line number 3 are connected. A specific example of a representative number connection system in this exchange is a relay stand system, but this embodiment does not specifically limit the system.

When the request is completed, the representative number control means 103 deletes the information registered in the representative number database 105,
Return to the state shown in FIG. 2(a).

Next, an example of a conference held between four terminals E, F, G, and H will be explained using FIG. 4. Similarly, when the representative number control means 403 receives conference information from the conference reservation system, it performs the following control. First, since the number of terminals to be connected to the multipoint conference unit is four, four terminals are selected from the boats provided in the center node. Now assume that these are boats with line numbers 3, 4, 5, and 6, respectively.

Next, the representative number control means 403 assigns one representative number to these four boats. Let's call this number 10 now. Representative number again! The trlJ control means 403 uses these four
One boat is assigned to the multipoint connection unit 401 as a connection boat. In other words, the representative number 10 is assigned to the multipoint conference unit}401. Next, the representative number control means 403 registers in the representative number database 405 the set of line numbers of the four boats corresponding to this representative number 10. This situation is similarly shown in FIG.

FIG. 2(a) shows the contents of the representative number database when no conference is set, that is, when nothing is registered. Next, FIG. 2(C) shows the contents of the representative number database when the representative number control means registers a set of four ports corresponding to the representative number 10. The conference reservation information and representative number are sent to each terminal E, F, G.
, H are sent in advance in the same way. After the above control, the exchange performs connection control in the sequence shown in FIG. 5(a) as an example. That is, at the conference start time, each terminal E, F, G, and H makes a call to the exchange 404 using number 10 as the representative number. The exchange 404 determines from the information in the representative number database 405 that the representative number 10 indicates the ports of the center node's line numbers 3, 4, 5, and 6, and calls the center node to control the connection. . As a result, the terminal and the multipoint conference unit are connected and a conference can be held as shown in FIG. 5(b). Figure 5(b) shows an example in which terminal E and the port with line number 3, terminal F and the port with line number 4, terminal G and the port with line number 5, and terminal H and the port with line number 6 are connected. There is. When the meeting ends, the representative number control means 403
deletes the information registered in the representative number database 405 and returns to the state shown in FIG. 2(a).

(Effects of the Invention) As shown in the embodiments above, in the representative number control system for multipoint conference connection according to the present invention, prior to the conference, as many boats as the number of connection points are selected and connected to the multipoint conference unit. Furthermore, a representative number representative of the line numbers of those boats is assigned and registered in a representative number database provided in the exchange, and when the conference ends, the registration of the registered representative number is deleted. In this way, by dynamically performing controls such as assigning, registering, and deleting representative numbers for each conference held in response to the multipoint conference unit of the center node that a terminal attempts to connect to, it is possible to always use as many ports as necessary. The efficiency of using the line ports of the center node is significantly improved compared to the conventional method.
