Abstract

PURPOSE:To process a user's message without being conscious of a processor to be received for each message by providing a function making a point code in each No.7 signal link control processor coincident with a content of state management data of a sub system to a multi-processor type system in which plural No.7 signal link control processors with a signal connection control section in a No.7 common line signal system mounted to them are in existence. CONSTITUTION:The system is provided with a common management processor 1 implementing the state management of a sub system and a point code, each of No.7 signal link control processors 2-4 transfers the management message to the common management processor 1 and the common management processor 1 informs a state change to each of the No.7 signal link control processors 2-4.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
No. 7 equipped with a common line signaling system signal connection controller 7
The signal link control processor has one processor in one system, and the state management method in the multiprocessor configuration was not considered.

[0004]

The state management system of the signal connection control unit according to the present invention is No. C in 7 common line signaling
CITT Recommendation Q. 711 to 714, a plurality of Nos. 7 of the multiprocessor type system having a 7-signal link control processor. 7 common link processor for managing the signal link control processor, The signal connection control unit of the No. 7 signal link control processor transfers the message accompanied by the state change of the subsystem to the common management processor; The signal connection control unit of the 7-signal link control processor is provided with notifying means for notifying the point code or the state change of the subsystem.

Then, each of the above No. 7 The signal code control processor is characterized in that the point code and the content of data for managing the state of the subsystem are always matched to process the user's message.

[0006]

The present invention will be described below with reference to the drawings. 1 is a block diagram showing an embodiment of the present invention. 7 shows the positioning of the 7-signal link control processors 2, 3 to 4.

The common management processor 1 is No. 7 Signal link control Processors 2 to 4 carry out the status management of subsystems and point codes collectively based on the content of the management message of the signal connection control transferred via the communication bus 5, and the status changes. Communication bus 5 if there is
Via each No. 7 Signal Link Control Processor 2, -4
Notify to.

2 to 4 are block diagrams for explaining the detailed procedure of this embodiment, and FIG. No. 7 signal link control processor to the common management processor transfers the message accompanied by the state change of the subsystem. 7 shows the state change notification processing of the subsystem to the 7-signal link control processor, and FIG. 4 shows the user message transfer processing (in the case of a relay station).

Common management processor 1, No. 7 signal link control processors 2 to 4 are each a signal connection control unit 1
1, 21, ~ 41 and state management data 12, 22, ~ 4
2 and message transfer units 13, 23 and 43, and the message transfer units 23 to 43 transfer a message accompanied by a change in subsystem status to the common management processor 1 via the communication bus 5.

In FIG. No. 7 that received the UDT (SSA: Subsystem Acceptance) message transmitted via link 7 The signal connection control unit 41 in the 7-signal link control processor 4 transfers the message to the signal connection control unit 1 in the common management processor 1 via the communication bus 5. Upon receiving the message, the signal connection control unit 11 in the common management processor 1 interprets the message,
The state of the relevant subsystem in the state management data 11 in the own processor is rewritten to allow.

In FIG. 3, the signal connection control unit 11 in the common management processor 1 indicates that the status of the subsystem has changed via the communication bus 5. 7 signal link control processor 2, No. 7 Signal Link Control Processor 4 is notified. No. which received this. 7 signal link control processor 2, No. The 7-signal link control processor 4 rewrites the status of the corresponding subsystem in the status management data 22 and 42 in each processor.

In this embodiment, the common management processors 1 and N are
o. 7 signal link control processor 2, No. Since the contents of the state management data 5 held by the 7-signal link control processor 4 are matched according to the above procedure, even if the UDT message is relayed as shown in FIG. N without being aware
o. 7 signal link control processor 2, No. The reception processing may be performed by either of the 7-signal link control processor 4.

[0013]

As described above, according to the present invention, a plurality of N
o. 7 has a common management processor for managing the 7-signal link control processor. The signal control unit of the No. 7 signal link control processor transfers a message accompanied by a state change of the subsystem to the common management processor. No. 7 signal link control processor is notified of the point code or the status change of the subsystem by the signal connection control unit. No. 7 signal link control processor has the point code and the contents of data for managing the status of the subsystem always match. 7
It has an effect that a user's message can be processed without being aware of the multi-configuration of the signal link control processor.
