Embodiment Construction

[0097] The main thought of the method of the present invention is: pre-set routing policy decision point (RPDP), and route policy information is set in RPDP, when GMSC sends route inquiry request to HLR, RPDP adopts interception MAP signaling mode, obtains this route inquiry request , and use the routing query request as a routing decision query request for subsequent routing policy judgment and control processing. Finally, RPDP will determine the current routing decision information based on the current routing policy information and the routing decision-related information stored in the CS / IMS domain. And send the routing information determined according to the current routing decision to the GMSC, and the GMSC performs routing control according to the received routing information.

[0098] Routing decision-related information can be stored in the user subscription server, which can be the HLR in the CS domain, or the HSS in the IMS domain, or a combination of both HLR and HS...

Abstract

The invention relates to a method for controlling route and relative system. Wherein, said method presets one route strategy decide point RPDP to store the route strategy information; when RPDP holds up the route inquire request of GMSC sent to the HLR, according to the strategy and if the user can be reached in different fields, confirming the field-span route control in the service supplied by CS / IMS, while the connected route is strengthened. The invention avoids modifying HLR, and when the access network can not support CAMEL or the user affects the activation triggered by called CAMEL service, and the access is closed decided by operator, it can realize route control.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a system and method for realizing routing control. Background technique [0002] Starting from the third generation mobile communication standardization partnership project (3GPP) R5 phase, the universal mobile telecommunications system (UMTS) core network is divided into circuit switched (CS, Circuit Switched Domain) domain, packet switched (PS, Packet Switched Domain) domain and IP The multimedia subsystem (IMS, IP Multimedia Subsystem), in which the CS domain is used to provide users with circuit-type service connections, including MSC (MSC Server / CS-MGW), gateway mobile switching center (GMSC), network interworking function unit ( IWF). Mobile Switching Center (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 ca...
