Method for carrying out signal switching between different standard systems

Abstract

The present invention provides signalling switch over method between different standard systems, to realize communication protocol intercommunication in different standard system of network of communication. It contains use signalling link inserting signalling switch over platform in different protocol standards end office, link pair consisting of data link and submitting signalling switch over platform management, providing signalling connection between end office and signalling switch over platform, signalling switch over platform receiving one side end office sent signalling, through codingdecoding and signalling conversion transmitting message to opposite side end office to complete signalling switch over. The present invention possesses good mobility and versatility and saves telecommunication operating cost.

Description

technical field [0001] The invention relates to a signaling system and switching technology in the field of communication, in particular to a method for realizing communication protocols intercommunicating among different standard systems in a communication network. Background technique [0002] The signaling network is an important part of the communication network. The No. 7 signaling system adopts the public channel signaling method. Due to the separation of the communication channel and the signaling channel, it has large signaling capacity, fast transmission speed, and can transmit and remove circuits. The advantages of connecting various business control signals and data other than signaling have been widely used in communication networks. [0003] figure 1 It is a schematic diagram of the basic structure of the existing signaling network, in which SP (Signaling Point) and STP (Signaling Transfer Point) establish connections at various levels of SS7 through links. ...

AI Technical Summary

Problems solved by technology

[0006] Question 1. Most switches on the telecommunications network can support the ISUP protocol, but many of these switches can only support one type of ANSI standard or ITU standard, and cannot support both types of standards at the same time;

[0007] Question 2. There is a difference between the ISUP protocol of the ITU standard and the ANSI standard. Direct connection will cause errors in message recognition, and even make the connection impossible to complete and normal intercommunication.

This solution can effectively solve the above problems, but the introduction of the tandem office makes the network structure complex, and the cost of transformation is high; the data configuration of the end office needs to be changed; it takes up a lot of resources, especially when different types of protocols need to be connected When there are many end offices, the cost will be greatly increased
