Abstract

This invention discloses a method for transmitting information on signaling kinks based on No.7 signaling system containing a sending end and a receiving end directing to the link or connecting with the link by a switch point. The method includes 1. adding a virtual relay in the exchange device of send / receive ends, each one is assigned with corresponding circuit identification code(CIC) and arranged in the virtual relay group, the said information includes the route information corresponding to the virtual relay 2. The sending end selects the information only needing transferred on the signaling link to be transmitted to the receiving end by the virtual relay which utilizes original parameters, adaptive parameters or self-defined ISUP information to transfer necessary information.

Description

technical field

[0001] The invention relates to the field of telecommunications, in particular to a method for transmitting messages on a signaling link based on the No. 7 signaling system. Background technique

[0002] No.7 signaling system is an international and standardized general public channel signal system, which can meet the requirements of various communication services, can be used in telephone network, intelligent network and integrated digital network, etc., and can also be used as a reliable No. 7 signaling system is an indispensable support system leading to the development of network integration and intelligence.

[0003] The basic structure of No.7 signaling is mainly divided into message transfer part (MTP), signal connection part (SCCP) and user part (UP). Among them, the user part (UP) includes the ISDN user part (ISUP), which defines the signal procedures of the ISDN communication network and the messages and message codes to realize these procedures. ...
