DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a group signal receiving system for a multiprocessor exchange having a plurality of call processors and line resource management processors. The present invention relates to a group signal receiving method in a multiprocessor exchange for realizing a method of distributing a group.

[0002]

2. Description of the Related Art In a conventional multiprocessor exchange, since line resource management and call state management are performed by one processor, there is no need to distribute group signals.

[0003]

In the conventional group signal receiving method described above, only one line resource management and one call state management are realized, and a plurality of line resource management processors and a call processing processor are provided. There is a problem that such a multiprocessor switch cannot be used.

[0004]

According to the present invention, a group signal receiving system in a multiprocessor exchange according to the present invention comprises a plurality of line resource management processors and a line resource management for centrally managing whether a trunk line is empty, in use, or closed in a multiprocessor exchange. A system configuration including a plurality of call processors for managing a call state by signal transmission / reception of a relay line to a processor, and a line having the same point code is accommodated in the plurality of call processors and the line resource management processor. In this case, a group signal distribution processor is provided, and the line is managed by the group signal distribution processor .
A group signal is distributed to the line resource management processor.

[0005]

According to the present invention, under the condition that a line having the same point code is accommodated in a plurality of call processors and line resource management processors, the No. 7 signaling system of the integrated services digital network (ISDN) is used. Enables reception of group signals.

[0006]

FIG. 1 is a block diagram showing an embodiment of the present invention, and shows an example of the configuration of a system showing a combination of a group signal distribution processor, a line resource management processor and a call processing processor. In FIG. 1, 1 is Kosho
Physical processor, 3 empty trunk line, in use, in line resource management processor to centrally manage during occlusion, and a round wire resource management processor 3-1, 3-2 and 3-3. 4 is a plurality of line resource management processors 3
And in the call processor that manages the call state by the signal transmitting and receiving trunk line for the line resource management processor 3-1 to 3-3, the call processor 4-1, 4-2 ...
4-4. Reference numeral 2 denotes a group signal distribution processor that has a line accommodation state of the entire system and distributes a group signal to a corresponding processor.

A group signal distribution processor 2 is provided when a line having the same point code is accommodated in a plurality of call processors and line resource management processors.
The group signal distribution processor 2 is configured to distribute a group signal to the line resource management processor 3 for the corresponding line.

FIG. 2 is an explanatory diagram showing an example of a line accommodation data configuration in the group signal distribution processor 2 in FIG. 1. PC indicates a point code, and CIC indicates a line number.

FIG. 3 is a flow chart for explaining the operation of FIG. 1 and shows a flow chart in the group signal distribution processor 2. In this flowchart, predetermined processing is executed in each of steps 101, 102,... 107.

Next, the operation of the embodiment shown in FIG. 1 will be described with reference to FIGS. Here, the reception of the group block signal will be described. First, the call processor 1 receives the group block signal and sends it to the group signal distribution processor 2 as it is. The group signal distribution processor 2 reads the line accommodation data shown in FIG. 2 which is the received group block signal (step 102 in FIG. 3), and distributes the signal to the corresponding line resource management processor 3 (step 103 in FIG. 3, 10
4).

[0011] Next, the call processing processor circuit resources management processor 3 that manages the call state of the corresponding line
4 for signal distribution. The distribution here is the CI shown in FIG.
This is performed using the lower two bits of C (line number). Then, upon receiving the signal, the call processor 4 changes the call state to the closed state, and notifies the line resource management processor 3 of the end of the processing after the end of the processing. The line resource management processor 3 that has received the notification of the end of this processing rewrites the state of the resource management table while the partner station is closed, and notifies the group signal distribution processor 2 (step 105 in FIG. 3).

After receiving all the processing end notifications from the line resource management processor 3 that has distributed the signal (Yes in step 106 of FIG. 3), the group signal distribution processor 2 blocks the other station through the call processing processor 1. A response signal is returned (step 107 in FIG. 3).

[0013]

As described above, according to the present invention, by adding a group signal distribution processor, the same point code can be used in a multiprocessor exchange having a plurality of line resource management processors and a plurality of call processors. This makes it possible to receive the group signal when the group signal is accommodated in the processor of the present invention.
