Problems solved by technology

However, in the IMS network, the relationship between the Home Subscriber Server (HSS) storing user service subscription information and the call session control function entity (Call Session Control Function, CSCF) of the session control network element is based on the Diameter protocol. Code operation and corresponding parameters, and the existing CSCF does not have the function of pre-inserting the trigger code, so in the existing IMS, the trigger code cannot be obtained through a similar method in the fixed network intelligent network, and the user cannot Use the services provided by other non-IMS networks by means of service trigger codes

Abstract

The invention discloses a method and a system for anchoring service routing in an IP multimedia subsystem. The method comprises correlating a first service provided by a non-IMS (IP multimedia subsystem) network with a special domain name, and in an IMS network, setting the AS (application server) address parameters in an iFC (initial filter criteria) triggering the first service as a corresponding special domain name; when a CSCF (call session control function) in the IMS network receives a calling request message to trigger the first service, filling the special domain name into the routing field of the calling request message, and based on special domain name analysis, sending the calling request message to a unified media gateway. Based on the correspondence between the special domain name and a service triggering code of the first service, the unified media gateway obtains the service triggering code of the first service and inserts the service triggering code before the called number of the calling request message to route the calling request message to a corresponding SCP (signaling control point) in the non-IMS network. The method and system for anchoring service routing in the IP multimedia system achieves anchoring of the service routing from the IMS network to the non-IMS network, and a user can use the service of the non-IMS network through access to the IMS network in a service triggering mode.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for anchoring service routing in an IP multimedia subsystem. Background technique [0002] In recent years, the acceptance of traditional fixed-line users based on the IP Multimedia Subsystem (IMS) has become one of the main driving forces for operators to deploy IMS networks. In an IMS network, after a traditional fixed user triggers a service, the IMS network needs to enable the fixed user to continue to obtain the original fixed network intelligent service in addition to providing the fixed user with IMS basic services and supplementary services. Existing fixed network intelligent services include services such as collaborative communication services and iVPN. [0003] Among these fixed network intelligent services, some services are provided by a service control point (Signaling Control Point, SCP) based on the Intelligent Network Application Protocol (Intellige...
