Problems solved by technology

[0005] However, the implementation method of the existing technology abandons the commonality and runs two independent signaling versions at the same time on one signaling point, which complicates the signaling system and increases the amount of system maintenance and instability factors.
[0006] Patents and documents that can solve the above-mentioned prior art problems have not yet been retrieved

Embodiment Construction

[0020] Whether it is the broadband link layer protocol SSCF-NNI or the narrowband link layer protocol MTP2, the primitive definitions between them and MTP3 are exactly the same. To realize the integration of wideband and narrowband signaling, a single interface needs to be used in the signaling system, and most of the differences between wideband and narrowband are limited below their respective link layers. which is:

[0021] In the MTP3 protocol layer, there are three signaling links for wide and narrowband signaling systems, namely 64K, 2M and broadband links. Three kinds of links are uniformly numbered, which is convenient for signaling management; only the category item is added to the link attribute, and it is used when it is necessary to distinguish the wide and narrowband attributes of the link;

[0022] The format of the MTP3 management message is only the switch request and switch response messages, which need to be processed separately for different links; the leng...

Abstract

The method is as the follows: interface for MTP3, SSCF-NNI and MTP2 are defined uniformly, classification is added is attribute of signalling link, the maximum support length of MTP3 in revised at MTP3 / b layer, compatibility processing of MTP3 protocol is carried out and supporting wide band message processing of SCCp module is carried out.

Description

technical field [0001] The present invention relates to the realization method of the No. 7 signaling system, in particular to the realization method of the processing system which realizes the integration of wideband and narrowband signaling at MTP3 (messagetransfer part3) and above protocol layers. Background technique [0002] In the third-generation mobile communication products, the signaling part includes both the broadband signaling system carried on ATM and the narrowband signaling system carried on E1 or T1. [0003] The link layers of the two signaling systems use different protocols, namely the MTP2 protocol and the SSCF-NNI and SSCOP protocols, but the mode of the interface part of the two is basically the same as that of MTP3: the processing of the MTP3 / b (broadband message transfer part3) layer, in MTP3 On the basis of the protocol, modifications are made to adapt to broadband, including the format of switching request and switching re...
