Problems solved by technology

[0006] It can be seen from the prior art that when there are multiple signaling routes between the source signaling point and the target signaling point, regardless of the load sharing mode or the active / standby mode, different service messages are selected in the same routing mode. Signaling routing, so it cannot meet the networking requirements of selecting different signaling routes for different business messages during network evolution

Embodiment Construction

[0035] In the M3UA protocol, AS (Application Server, application server) is a logical entity that serves a specific routing key, such as: processing a specific range of PSTN (Public Switched Telephone Network, public switched telephone network) trunks (by SIO (Service Information Octet , service information octet), OPC (Originating Point Code, source signaling point code), DPC (DestinationPoint Code, destination signaling point code) and CIC (Circuit Identification Code, circuit identification code) range to limit) calls or handle all HLR (HomeLocation Register, home location register) transaction virtual database. These SIO, OPC, DPC, CIC ranges or SCCP SSNs can form a routing key, identified by a unique routing context. When the M3UA of the signaling gateway SG distributes the message from SS7 to each AS, it can obtain relevant information from the message, such as routing key information such as SIO, OPC, DPC, and CIC, and use it to form a routing key to send the message ...

Abstract

The invention discloses a method and device for selecting signaling routes for different service messages, by the obtained service message mark, target signaling point code and source signaling point code corresponding to service message of an upper user, determining corresponding signaling route for the service message, so as to be able to meet the networking requirements for selecting different carrying signaling routes for different service messages in the network evolution course.

Description

technical field [0001] The invention relates to the communication field, in particular to the technology for selecting signaling routes for different service messages. Background technique [0002] With the development of IP-based telecommunication networks, the traditional No. 7 signaling network based on TDM (Time Division Multiplexing, Time Division Multiplexing) is gradually transitioning to IP-based. MTP (Message Transfer Part) based on TDM The transport protocol evolves to the M3UA (MTP3 User Adaptation) transport protocol based on IP bearer, and the ISUP (ISDN User Part, ISDN User Part) relay signaling evolves to the BICC (bearer-independent call control protocol) relay signaling. In the evolution process, in order to ensure network stability and service continuity, a gradual evolution method is generally adopted, so that different service messages may coexist. [0003] For example, if figure 1 As shown, the traditional signaling exchanged between the switching offi...
