Problems solved by technology

[0007] In summary, because the QoS resource reservation method in the prior art cannot guarantee the establishment of the QoS resource reservation premise, the called terminal has ringing, and then the call is interrupted and the conversation cannot be made.

Embodiment Construction

[0049] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings.

[0050] The QoS resource reservation system in the embodiment of the present invention includes a sender, configured to send a SIP request message carrying an SDP Offer to a proxy server; a proxy server, configured to receive the SIP request message carrying an SDP Offer sent by the sender, and to The SDP Offer in the above SIP request message is used to perform the QoS resource reservation operation. When the sending party is the calling terminal, the proxy server is the calling side proxy server; when the sending party is the calling side proxy server, the proxy server is the called side proxy server; when the sending When the party is the called terminal, the proxy server is the called side proxy server; when the sender is the called side proxy server, the proxy server is the calling side proxy server.

[0051] Referring to Fig. 1, the Qo...

Abstract

The method comprises: the proxy server receives the session initiation protocol (SIP) request message carrying the session description protocol offer (SDP Offer) from sending end; according to SDP Offer in the SIP request message, making QoS resource reserving operation.

Description

technical field [0001] The present invention relates to the communication field, in particular to a QoS (Quality of Service, service quality) resource reservation method and system, and a session establishment and media modification method. Background technique [0002] In recent years, the session-based dynamic QoS control mechanism has gradually become a research direction. Under this architecture, the control plane perceives the QoS resources required by the session, and performs admission control on the QoS resource requests required by the session. The execution of the QoS policy approved by the service plane is completed on the media plane. This session-based dynamic QoS control mechanism can not only provide strict QoS guarantee, but also has good scalability. At present, many standard organizations are studying similar mechanisms, such as IETF (Internet Engineering Task Force, Internet Engineering Task Force), ITU (International Telecommunication Union (Internationa...
