Abstract

The invention relates to a method for confirming the quality of data transmission service in the communication network, to improve the utilization efficiency of transmission resource. Wherein, when deciding the QoS, using the request message of UE to the QoS, as well as using the network information or operation information as user contrast strategy information, service strategy information, access type, position strategy information and access network local service strategy. Based on IMS or similar network, said network information or operation information can be obtained by P-CSCF to be sent to the PDF to be decided, or obtained by P-CSCF to be projected into uniform propriety according to the local set, to be sent to the PDF, or obtained and stored by S-CSCF, and modify the SDP description when user initializes the service request or reject the service request.

Description

technical field

[0001] The present invention relates to a quality of service realization technology, in particular to a method for realizing quality of service in an Internet Protocol Multimedia Subsystem (IPMultimedia Subsystem, "IMS" for short) and similar networks. Background technique

[0002] IMS is an IP multimedia subsystem in the WCDMA network defined by the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") R5 / R6 standard. Target network for business and applications. The IMS uses the IP packet domain as the bearer channel for its control signaling and media transmission, and uses the Session Initiation Protocol (SIP) protocol as the call control signaling to realize the integration of service management, session control and bearer access. The three are separated.

[0003] The main functional entities in IMS include:

[0004] Call Session Control Function (Call Session Control Function, referred to as "CSCF"), used to c...
