Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connection control method for a communications switching network, and more particularly to a connection control method for a manual switchboard.

Conventionally, incoming calls for call requests were handled by the incoming call center, such as toll stations that handled 100 number calls and international exchanges that handled international calls, but recently two A method is being considered in which data is transferred and handled at intervals (or longer) depending on the operating status of the switchboard. An example of this will be explained with reference to FIG.

Stations A and B mutually count the number of waiting calls on the switchboards EBA and EBB, and check the operating status of the switchboards using the modem.
Notification is made via data line d through MDA and MDB. A call INB that comes into the exchange SWB of station B selects the one with the lower load between the exchange EBB of its own station (station B) and the exchange EBA of station A, and if the load on station A is lower, it is contacted. After connecting to the exchange SWA of the A station through the line 1 and being handled by the exchange SWA of the A station, the outgoing line
Connected to OUTA.

On the other hand, if the outgoing line is an expensive line such as an international line, there are two outgoing stations (multiple stations) to the same destination.
A method is used to connect the outgoing lines by making a detour connection to each other. This will be explained with reference to FIG. For a call INA that comes into station A (this is the same for calls originating from the switchboard, but will be omitted in this explanation), if the outgoing line OUTA of the own station is busy, the outgoing line status of station B is sent to the data line d. Obtain it, and if the detourable line is empty, use the contact line l
connect to B station's exchange SWB through
Connect to OUTB.

If the above two methods exist at the same time, for example, B
A case may be considered in which an incoming call to a station is handled by the switchboard of the A station and then connected to the outgoing line of the B station. In other words, this is a case where the communication line between A and B is used to go back and forth.

The present invention makes it possible to connect within the B station by using the switchboard of the A station, without having to reciprocate the communication line between the A station and the B station, even when the above two systems coexist.

According to the present invention, there is provided a means for mutually transferring operating status information of exchange stations installed in a plurality of exchange stations and busy status information of outgoing lines, and means for remotely controlling the switching equipment of the first station, and the system includes means for remotely controlling an incoming call to the second station from the first station to the second station based on operating status information of the switching boards of the second station and the first station. If it is determined that the load is heavier, the load is transferred to the first station, the reception and outgoing processing is performed at the switchboard of the first station, and the outgoing line status of the second station and the first station is transferred. Based on the information, if the outgoing line of the first station is busy and the outgoing line of the second station is empty, the first station's switchboard controls the handling of the second station's switchboard. A connection control system for a communications switching network is obtained, which is characterized in that the incoming line of the second station and the outgoing line of the second station are connected.

Next, an embodiment of the present invention will be described with reference to FIG. FIG. 3 is a block diagram of an embodiment of the present invention, in which an incoming call (INB) to station B is determined to have a lower load on station A than the operating status of the switchboard.
Connected to the central office exchange EBA. After the A-station switchboard EBA performs reception processing, it performs a connection operation to the outgoing line OUTA. When the switchboard SWA of station A learns that there is no outgoing line OUTA for its own station, it switches to the outgoing line of station B
Look for OUTB. If there is an empty line OUTB of B station, A
The connection request from the central office exchange EBA is transferred to the B station through the data line d, and the incoming line INB and outgoing line are connected at the B station.
Performs control to connect OUTB and disconnect connection line l.
Remote control from the switchboard during this time can be realized using conventional technology, so a detailed explanation will be omitted. The A station's switchboard EBA is restored, and the connection train is carried out only within the B station. If the call now calls the switchboard again, it is connected to the B-station switchboard EBB.

As explained above, the present invention enables a plurality of switching centers having manual switching boards to operate effectively by combining the operating status of the switching board, the outgoing line idle/busy information, and the remote control system of the switching board. I can do it.

Claims (1)

[Claims] 1. Means for mutually transferring operating status information of exchange stations installed in a plurality of exchange stations and busy status information of outgoing lines, and a means for mutually transferring information on the operating status of exchange stations installed in a plurality of exchange stations, and a means for mutually transmitting information on the operating status of exchange stations installed in a plurality of exchange stations, and exchange equipment of other stations from each of the exchange stations installed in the plurality of exchange stations. It has a means for remotely controlling incoming calls to the second station from the first station to the second station based on operating status information of the switching boards of the second station and the first station. When it is determined that the load is heavy, it is transferred to the first station, the reception and outgoing processing is performed at the switchboard of the first station, and the outgoing line status information of the second station and the first station is used. If the outgoing line of the first station is busy and the outgoing line of the second station is empty, the first station's switching board controls the handling of the second station's switching board, and the second station's outgoing line is busy. A communication switching circuit network connection control system characterized by connecting an incoming line of a second station and an outgoing line of a second station.
