Abstract

The present invention discloses a method and system for realizing the bearer resource control function. The method includes: UE sends out a call request, and the address control network element inserts the UE's real address and media stream information into the extended parameters carried in the SIP signaling of the call request and send it to the P-CSCF network element; the P-CSCF network element obtains the real address and media flow information from the extended parameters; the P-CSCF network element maps the real address and media flow information to the PCRF network element, and then sends the PCRF The network element sends a bearer authentication request message. The present invention inserts the UE's real address and media stream information into the extended parameters carried by SIP signaling to realize the technology of QoS bearer resource reservation and authorization management when the P-CSCF network element and the address control network element are separately set, overcoming the Defects described in the protocol.

Description

technical field [0001] The invention relates to the field of IMS (IP Multimedia Core Network Subsystem, IP Multimedia Subsystem) address control network element access user field, in particular to a method and system for realizing bearer resource control function. Background technique [0002] In the traditional PSTN (Public Switched Telephone Network, Public Switched Telephone Network), QoS (Quality of Service, Quality of Service) has always been attached great importance to. Since traditionally transmitted services are relatively single, and the network's operating area is also relatively simple, it is only necessary to The transport layer only needs to guarantee a certain QoS. The code stream transmitted in NGN (NextGeneration Network, next-generation network) can be low-speed, high-latency non-real-time data, high-speed, low-latency multimedia stream, or these real-time non-real-time data streams. The coexistence of data streams of these different media requires stricte...
