As a result, the amount of communication between the call processor 2-i and the management processor 3 increases, which puts pressure on the processing capacity of the call processor 2-i and the management processor 3, resulting in a problem in that the time required to set up a communication path is extended.

[Means for solving problems]

FIG. 1 is a diagram showing the principle of the present invention.

In FIG. 1, 100 is a communication path network, 200 is a call processor, and 300 is a management processor.

Reference numeral 400 denotes a channel information storage means attached to each call processor 200 according to the present invention.

Reference numeral 500 denotes a communication path information storage means attached to the management processor 300 according to the present invention.

Each channel information storage means 400 stores the idle/blocked state of some channels set within each channel yI100 managed by the corresponding call processor 200.

In addition, the communication path information storage means 500 stores information about each communication path network 100.
The empty/blocked states of the remaining communication paths set within the call path are stored.

A part of Sm, for example, tie 1, thrower 1-TSa to TSg does not indicate an empty/occupied state, and empty/occupied information Hb is stored.

On the other hand, map memory (M
P) 4 is provided with communication path network corresponding areas 41 to 4n corresponding to all communication path networks 1-1 to 1-n, and each communication path network corresponding area 41 has respective communication path networks 1-1 to 1-n. Road!
The vacancy information is stored in each map memory 8-i of each time slot TSa to Tsm% on the incoming highway 16 and each time slot TSa to TSm on the outgoing highway 17 in 1ll-i. Empty/busy information tab is stored that indicates the vacancy/busy state of time slots other than time slots TSa to TSg, that is, time slots TSh to TSm.

In FIGS. 2 to 4 and 6, the call processor 2-i that needs to set up a call path analyzes the accommodation position number of the outgoing line for which the call path is to be set up (step 53 in FIG. 4).
1).

Since the accommodation location number of the outgoing line includes the accommodation channel network number, the call processor 2-i analyzes the accommodation location number to determine whether the outgoing line is accommodated in the managed communication channel M41-i, that is, if the same call It is possible to identify whether the connection is within the processor (CPR) 2-1 (step 532).

As a result of the identification, if it is found that the outgoing line is accommodated in the communication path IM1i that is managed by the call processor 2-i itself,
That is, when it is determined that the connection is within the own call processor (CPR) 2-1, the call processor 2-i refers to the attached map memory 8-i and records the time slots TSa to TSg on the human highway 16 and the output. A communication route is selected using the same time slots TS, which are both vacant, from time slots TSa to TSg on the highway 17 (step 533).

If the selection is successful (step 534), the call processor 2-+ immediately controls the primary time switch 12, the space switch 13, and the secondary time switch 14 in the call path %f41-i to set up the call path. .

Note that in step S32, if it is determined that the outgoing line is accommodated in a communication network other than the communication network 1-i that is managed by the call processor 2-1 itself, that is, the call processor 2-1 itself
CPR) If it is determined that the connection is not within 2-i,
Alternatively, if the selection is not successful in step S34, the call processor 2-4 requests the management processor 3 to select a communication path (step 535).

The management processor 3 refers to the attached map memory 4, selects an empty communication path, and transmits the selection result to the associated call processor 2-1 (steps S41 to S543) in the same manner as described above.

The call processor 2-1, which has received the selection result from the management processor 3, selects the next time switch 12 and the space switch 13.
and the secondary time switch 14 based on the selection result, and the selected communication path is set on the communication path network 1-1 (step 536).

For example, the uplink 5 accommodated in the 11T1 channel network 1-1
When connecting the PB signal receiver 6-1 accommodated in the same communication path network 1-1, the communication path 'fi41
The call processor 2-1 that manages the PB signal receiver 6-1 analyzes the accommodation position number of the PB signal receiver 6-1, and
-1, the map memory 8-1 is referred to, and the empty/busy information ttab is found for both time slots TSa to TSg on the passenger highway 16 and exit highway 17.
selects the same time slot hTs that is free, and if the selection is successful, controls the primary time switch 12, space switch 13, and secondary time switch 14 in the communication path network 1-1 to switch the selected communication path. Set.

Next, when connecting the uplink line 5u accommodated in the communication path network 1-1 and the downlink line 7d accommodated in the communication path M41-n, the call processor 2-1 uses the accommodation position number of the downlink line 7d. If it is determined that the connection is not within the own call processor 2-1, the management processor 3 is requested to select a communication path. The management processor 3 that has extracted the selection request refers to the map memory 4 and obtains air blockage information on both the incoming highway 16 in the communication network corresponding area 41 and the outgoing highway 17 in the communication network corresponding area 4n. selects the same time slot TS that is free and transmits the selection result to the call processor 2.
-1 and 2-n. The call processor 2-1 is
The call route switch 2-n controls the primary time switch 12 and the space switch 13 in the call network 1-1, and the call switch 2-n controls the space switch 13 and the secondary time switch 14 in the call network 1-n, and selects Set up the communication path.

As is clear from the above description, according to this embodiment, when the call processor 2-i identifies a connection within its own processor,
Since a free call path is selected by referring to the attached map memory 8-i without requesting the management processor 3 to make a selection, the amount of communication between each call processor 2-1 and the management processor 3 is reduced. A decrease in the processing capacity of each call processor 2-i and management processor 3 is prevented.

Note that FIGS. 2 to 4 and 5 are merely examples of the present invention, and the configurations of the communication path network 1-1 and map memories 4 and 8-4 are limited to those shown in the figures. Although many other modifications may be considered, the effects of the present invention remain the same in any case.
