INTER PROCESSING METHOD OF CCITT NO.7 SIGNAL IN DISTRIBUTED STRUCTURE SWITCHING SYSTEM

摘要

The present invention can be applied to a common line signal network user unit (ISUP), a telephone user unit (TUP), an intermediate service unit (ISP), a dialogue processing unit In the distributed structure exchanger, which guarantees the order of a series of messages in a specific signal relation by making the load of multiple message processors uniform for each message output from the application part (TCAP) It is easy to control by devising a common selection table for messages output from various common signal network user units (ISUP, TUP, ISP, TCAP), reducing waste of exchangers and providing easy maintenance Each of the output messages generated in the plurality of common line signal user sub-processors is divided into a single signal message And a message receiving step of receiving a user part output message from a user part common access control function block when a message is output to an arbitrary signal message processor in an arbitrary common signal signal user part processor A message type checking step of identifying a type of a message received in the message receiving step; a processor selection code separating step of separating a corresponding signal message processor selection code according to a message type identified in the message type checking step; A processor address extraction step of extracting a processor address from the signal message processor selection table with the selection code separated in the processor selection code separation step, a message addressed to the address extracted in the processor address extraction step As a transmission step, It is.
