Transmission apparatus, method for M3UA protocol based circuit identification code information and signalling network

Abstract

The invention provides a transmission device of circuit identification information which is based on M3UA protocol. The invention comprises an MTP3 protocol solid element of a signaling gateway module, an M3UA protocol solid element and an M3UA protocol solid element of an IP module, wherein the MTP3 protocol solid element of the signaling gateway module also comprises a conversion unit which is used for filling the middle four information of the circuit identification into the initial positions of a user protocol data domain when converting a plurality of messages of phone users in the MTP3 protocol solid element of the signaling gateway module into M3UA data message format. The device and the implementation methods of the invention solves the problem of the prior art that parts of the circuit identification are lost or the products of different manufactures have butt obstacles and thereby realizing the complete transmission of a CIC information and the butt of products of different manufactures without carrying the unused field of the protocol by using the initial field of the four user protocol data domains with the M3UA data message in the middle of the CIC information.

Description

Transmission device, method and signaling network of circuit identification code information based on M3UA protocol technical field The present invention relates to signaling network transmission technology, in particular to a transmission device for circuit identification code information based on the M3UA (MTP3-UserAdaptationlayer, No.7 Signaling Information Transfer Part (MTP) third-level user adaptation layer) protocol and its Implementation. Background technique In order to meet the needs of transmitting signaling protocols on IP networks, IETF (Internet Engineering Task Force, Network Working Group) set up a special signaling transmission group, and the IP network SIGTRAN ((SignallingTransport, signaling transmission protocol) protocol) they formulated supports the transmission of The IP network transports traditional circuit-switched signaling. As an important protocol of SIGTRAN, M3UA is widely used in the core network transmission part of mobile communication. T...

AI Technical Summary

Problems solved by technology

The present invention aims to solve the problem that the middle 4 bits of CIC information in the prior art are discarded or placed in an unused field when converted into an M3UA data message format, resulting in the limitation of the number of resources that can be used to undertake voice transmission and the problems caused by different manufacturers. To solve problems such as product docking barriers, a transmission device for circuit identification code information based on the M3UA protocol and its implementation method are provided, so as to realize the complete transmission of CIC information and the docking of products from different manufacturers without enabling the unused fields of the protocol
