Embodiment Construction

[0062] The present invention provides a method and equipment for optimizing network routing. For many services of users in the IMS network, there are two states of subscription and activation. optimization.

[0063] In the IMS network, the AS implements the service, and the S-CSCF routes the session to different ASs to complete the corresponding service according to the iFC rules downloaded from the HSS during the session. The data of HSS and S-CSCF are kept synchronous through the Cx interface in the IMS network.

[0064] The realization principle of the present invention is: add a dynamic service activation identity (Dynamic Service Activation Identity, DSAI) in HSS, when user terminal registers, download DSAI as part of user data from HSS to S-CSCF through Cx interface, when service When the change of the activation state causes the DSAI to change, the HSS can update the DSAI data in the S-CSCF through the Cx interface. And the HSS adds a new iFC trigger condition to the ...

Abstract

This invention relates to a method for optimizing network routes including: a, service CSCF judges if iFC trigger condition for expressing if a signed service of a user is activated is satisfied in an initial filtration rule from the user signed data of an attributed user server, b, CSCF determines if it routes said session to an applied server corresponding to the initial filtration rule. This invention also provides a device used in optimizing network routes.

Description

technical field [0001] The invention relates to the field of fixed and wireless communication networks, in particular to a method and equipment for network route optimization. Background technique [0002] 3GPP, 3GPP2, International Telecommunications Union (ITU-T), TISPAN under the European Telecommunications Standards Institute (ETSI) and other major standard organizations are working on the standard formulation of the next generation communication network (NGN), and have basically determined the following IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) serves as the core network of the next generation of fixed and mobile. Network evolution has seen the development trend of diversification of access technology and service provision, IP-based bearer, and unification of core network to IMS. Users can get better service experience in the IMS network. [0003] As shown in FIG. 1 , it is a schematic structural diagram of an existing IMS. Among them, the call session c...
