Abstract
A method and system for Quality of Service (QoS) during access negotiation are provided, which include that during media resource access negotiation, a calling side network element receives an INVITE 200 OK message from a called side terminal, detects that this call is under a SIP Forking scenario, only updates media resources negotiated by current session branch associated with the called side terminal, and does not process resource bearers negotiated by other session branches. A method and system for QoS bearer resource control during release is also provided, which include that during media resource release, a calling side network element receives a BYE message, and when detecting that this call is under an SIP Forking scenario, only releases media resources negotiated by current session branch, and does not process resource bearers negotiated by other session branches. By the disclosure, a resource bearer requirement of the SIP Forking scenario can be met.
