Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of signaling transfer protocol (Signal TransportProtocol is hereinafter to be referred as SIGTRAN) service processes (Server Process is hereinafter to be referred as SP) state consistency restoration methods.
Background technology
Institute's protocols having of the SP that describes in the SIGTRAN stack of the Internet engineering duty group (Internet Engineering Task Force is called for short IETF) definition includes M3UA, SUA, M2UA, IUA, V5U or the like.The SIGTRAN that relates to the SP description is used as legacy circuit-switched networks (Switched Circuit Network, hereinafter to be referred as SCN) domain signaling and User Agreement thereof be at the adapting protocol of IP network, mainly between IP territory peers include both node or SGW (SignalingGateway is hereinafter to be referred as SG) and IP territory end node, carry out adaptive to SCN domain signaling and User Agreement thereof.
The application scenario of SIGTRAN is divided into two kinds, please refer to Fig. 1.A kind of application is peers include both node (IPSEP) the some service interaction in the IP territory, the logical channel that SIGTRAN is used to carry SCN domain signaling and User Agreement data thereof is called IP operation service processes (Internet ProtocolService Process, hereinafter to be referred as IPSP), be divided into the client and server end.Another application is (IPSEP) mutual between SGW and IP territory end node, and the logical channel of SIGTRAN carrying SCN domain signaling and User Agreement data thereof is respectively signaling gateway process (Signaling Gateway Process is hereinafter to be referred as SGP) on the gateway and the application service process (Application Service Process is hereinafter to be referred as ASP) on the end node of IP territory.Logical channel under two kinds of application scenarios is commonly referred to as SP, and the SP of local terminal need safeguard the state of the relevant SP in opposite end.
Please refer to Fig. 2, the state of SP is divided into two classes, ASP_DOWN and non-ASP_DOWN.
