Abstract

The invention discloses a service quality control method and system in an IMS (IP multimedia subsystem) network. The service quality control method includes that a P-CSCF (proxy-call session control function) receives a service request initiated by a user through a user terminal; the P-CSCF recognizes whether quality of service (QOS) control on a service corresponding to the service request is triggered or not according to QOS control mark information aiming at a contracted service of the user of a local cache; a recognition result of not triggering QOS control is responded, and the P-CSCF forwards the service request to an S-CSCF (serving-call session control function); the S-CSCF returns a response message to the P-CSCF; the P-CSCF returns the response message of the service request to the terminal to start a service session corresponding to the service request. By the technical scheme, user service process of non-contracted QOS control services is simplified, service efficiency is improved, and network element burden is lowered.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for controlling service quality in an IMS network. Background technique [0002] The next-generation full-service converged network IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) can provide users with rich multimedia integrated services such as voice, video and data. How to ensure the service quality of multimedia services and meet the needs of customers with good perception is the key factor for mobile services to provide differentiated services that are different from Internet services. [0003] As users' business requirements are increasingly personalized, the network needs to be able to provide personalized and refined QOS policy control capabilities to different types of users to meet user needs at different levels. [0004] In the existing QOS control architecture, the application function entity cannot distinguish whether the user has subscribed for ...
