Embodiment Construction

[0029] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0030] As shown in Figure 3, it is a schematic diagram of the media stream distribution system in the SIP network in the embodiment of the present invention. It can be seen from the figure that in the embodiment of the present invention, when user 1 and user 2 request the same media stream through the edge node , only one media stream is established between the second media resource service unit and the first media resource service unit, and the first media resource service unit realizes the media stream distribution, and the media stream is distributed to multiple media stream requesting ends.

[0031] As shown in Figure 4, it is a flowchart of a method for distributing media streams in a SIP network in an embodiment of the present invention, and the method includes:

[0032] After the edge node receives the media stream request message sent by the...

Abstract

The invention discloses a method for treating media flow request in an SIP network, including that after the media flow request information transmitted by a media flow request terminal is received, a margin node transmits the media flow request information to a central node; the central node judges whether the current requested media flow is transmitted to the margin node by the central node; if yes, then the central node transmits indicating information to the margin node to indicate the margin node to transmit the requested media flow to the media flow request terminal; the margin node transmits the requested media flow to the media flow request terminal after the indicating information is received. The embodiment of the invention realizes to carry through media flow distributing treatment on the margin node, thereby saving a great deal of network resources and improving transmitting efficiency of the media flow, compared with the same media flow.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system and device for processing media stream requests in a SIP network. Background technique [0002] The SIP (Session Initial Protocol) protocol is an application-layer control protocol for establishing, changing and terminating multimedia sessions or calls. These multimedia sessions include multimedia conferences, distance learning, Internet telephony, etc. , Internet Engineering Task Force) standards organization definition. A network that uses the SIP protocol as a session control protocol is collectively referred to as a SIP network. [0003] IMS (IP Multimedia Subsystem) is the abbreviation of IP Multimedia Subsystem. It is a kind of SIP network. IMS is a subsystem superimposed on the packet network by 3GPP. As a service control protocol, the protocol uses the characteristics of SIP's simplicity, easy expansion, and convenient media combination to provid...
