Embodiment Construction

[0028] In order to make it easier for those skilled in the art to understand and realize the present invention, the embodiments of the present invention are described in conjunction with the accompanying drawings.

[0029] like image 3 As shown, in the M3UA protocol, the protocol data field in the data message is used to store the message content of the telephone user part. After M3UA receives the 24-bit telephone user part message from NIF (node ​​interworking function part) or MTP3 user (such as telephone user part / ISDN user part, etc.), it converts it into a data message and transmits it in the M3UA network. According to the M3UA protocol, the conversion rules are as follows:

[0030] The length of the SLS field is 8 bits, of which the lower 4 bits are used to store the SLS part of the TUP message;

[0031] The length of the OPC field is 32 bits, of which the lower 24 bits are used to store the OPC part of the TUP message;

[0032] The length of the DPC field is 32 bits...

Abstract

A loss free transparent transmitting method of circuit identification code includes receiving partial message of telephone user and converting said partial message to be data message , setting middle four bits of circuit identification code message on said partial message in unused field of data message and transmitting data message to transmission part of the third layer message .

Description

technical field [0001] The invention relates to a network communication technology, in particular to a method for lossless transparent transmission of circuit identification codes based on M3UA. Background technique [0002] The signaling system is the key technology of modern communication networks, and the reliable transmission of signaling messages by telecommunication equipment is the key to ensure the correct operation of the telecommunication network. In the traditional telecommunication network, there are already a series of norms and technologies to ensure the reliability of the signaling system, such as the currently mature narrowband No.7 signaling system. With the gradual maturity of IP packet network technology, IP packet network can be used to carry voice, data, multimedia and other services. The traditional circuit-switched network and packet network are in the stage of integration. In order to realize the intercommunication between traditional circuit-switched...
