Embodiment Construction

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

[0030] Such as image 3 As shown, 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 in A 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 implements media stream distribution, and the media stream is distributed to multiple media stream requesting ends.

[0031] Such as Figure 4 As shown, 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:

Abstract

A method for processing media flow request in SIP network involves that an edge node sends a media flow request message to a central node after receiving the media flow request message sent by a media flow request terminal (S401); the central node judges whether the current requested media flow is being sent to the edge node by the central node (S402); if yes, an indication information is sent to the edge node to indicate the edge node to distribute the requested media flow to the media flow request terminal, the requested media flow is distributed to the media flow request terminal after receiving the indication information by the edge node(S403). The method of the invention performs the distribution process of media flow at the edge node, thus reduces the quantity of network resources for identical media flow, and improves the efficiency of sending 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...
