Problems solved by technology

Assuming that there are multiple available paths between endpoints A and B, then for each endpoint, there may be multiple source addresses and destination addresses. When the coupling needs to switch the main path, if only the coupling primary path is changed The destination address of the channel is obviously not enough, but the IETF standard does not provide a detailed solution for how to change the source address of the coupling primary channel

Abstract

The method comprises: maintaining the preset parameters in the data structure of each communication path link-coupled under SCTP (stream control transmission protocol); determining the amount of SCTP link-coupled communication paths; determining the correlated relation between the source address and the destination address of each communication path; determining the main path; when needing to make the switch of main path, polling each SCTP link-coupled communication path except the main path to select a proper communication path as new main path.

Description

technical field [0001] The present invention relates to the technical field of the third generation mobile communication, and in particular, relates to the realization of the SCTP (Stream Control Transmission Protocol, Stream Control Transmission Protocol) multi-homing function in the WCDMA (Wideband Code Division Multiple Address, Wideband Code Division Multiple Access) system method. Background technique [0002] SCTP is a stream control transmission protocol used in IP networks. It is improved by IETF (Internet Engineering Task Force, Internet Engineering Task Force) on the basis of the original TCP (Control Transmission Protocol, Control Transmission Protocol). It is specially designed for signaling messages on IP networks. A protocol for transport, SCTP is a key part of building next-generation high-quality communications and e-commerce applications over IP networks. [0003] Compared with TCP and UDP (User Datagram Protocol, User Datagram Protocol), SCTP has two major...
