example 1

[0119] Method example 1: Distribution of connectionless messages sent by upper-layer users. Include the following specific steps:

[0120] - When the SIF receives a message from an upper-layer user, it obtains the destination point information (DPC or DPCSSN) and the local point code (OPC or OPCSSN) of the message from the called address and the calling address.

[0121] -Acquiring the status of the destination point in SCCP and SUA according to the destination point and the information of this point.

[0122] - According to the status of the destination point in SCCP and SUA, and the configured distribution strategy (load sharing, active backup), select the type of protocol to be transferred, and issue the message accordingly. If it is load sharing, it is necessary to implement SCCP and SUA service load sharing according to the call correlation of the upper layer, and keep the number of calls transmitted by SCCP and SUA equal; All call messages.

example 2

[0123] Method example two: Realize the distribution of connected messages through the connection ID resource pool.

[0124] When the message is a connection message, the interaction between the network side and the upper-layer user N primitive is realized according to the connection reference. The parameters of the connected N primitives in the protocol are defined in the following table:

Abstract

A method for making compatible of SCCP and SUA includes setting adaptive layer SIF on signaling connection control unit SCCP and up-layer of user message adaptive layer SUA on signaling connection control unit, utilizing SIF to distribute message for making compatible of SCCP and SUA when message is received by SIF. The device used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to the network field, in particular to a method and device compatible with SCCP and SUA. Background technique [0002] 1. Technical background of SUA protocol. [0003] With the application and popularization of softswitch technology, the traditional telecommunication network is developing towards the direction of intercommunication with IP network. Among them, the most critical issue is that No.7 signaling, which has been widely used, can be efficiently and reliably transmitted in the IP network. As early as 1999, IETF began to formulate the SIGTRAN protocol cluster based on IP technology, which mainly includes the adaptation protocol of the MTP layer of the No.7 signaling system to provide the transmission capability of No.7 signaling on the IP network. At present, IETF has further proposed the SCCP layer adaptation protocol of the signaling connection control part—SUA (Signalling Connection Control Part User Adaptation Layer,...
