Embodiment Construction

[0109] The main idea of ​​the method of the present invention is: pre-setting routing policy decision point, and routing policy information is set in routing policy decision point, routing decision query entity inquires current routing decision to routing policy decision point; Routing policy decision point is based on current routing policy information , and the routing decision-related information stored in the CS / IMS domain determine the current routing decision information; the policy decision point returns the determined current routing decision information to the routing decision query entity; the routing decision query entity completes subsequent routing control according to the routing decision.

[0110] Referring to shown in Fig. 1, the method that the present invention realizes cross-routing control comprises the following steps:

[0111] Step 101: The routing decision query entity queries the routing policy decision point for the current routing decision.

[0112] S...

Abstract

This invention discloses a method for realizing route control used in the route control including IMS domain and CS domain, in which, said method includes setting a route decision point in advance and designing route strategy information in the point, a strategy entity inquires about the current route decision to the point, which determines the current route decision information based on the current strategy information and related information kept in the CS / IMS domain, the point feeds back the current strategy information to the entity to finish the successive control based on the information. This invention also provides a system for route control.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a system and method for realizing routing control. Background technique [0002] From the 3rd Generation Partnership Project (3GPP) R5 stage, the Universal Mobile Telecommunications System (UMTS) core network is divided into Circuit Switched (CS, Circuit Switched Domain) domain, Packet Switched (PS) domain and IP Multimedia Subsystem ( IMS), where the CS domain is used to provide users with circuit-type service connections, including mobile switching center (MSC) (composed of MSC server Server / circuit domain media gateway (CS-MGW)), gateway mobile switching center GMSC, interworking function (IWF). MSC is used to complete the switching and signaling control functions of circuit-switched services; GMSC is an MSC that completes the routing and addressing function of mobile users in a certain network, and can be set up together with MSC or separately; IWF is used to b...
