Problems solved by technology

[0006] On the H.248 interface, streams are independent of each other. Except that they belong to the same Termination, there is no means to describe the binding relationship between them according to the existing protocol mechanism.

Embodiment Construction

[0029] The core idea of ​​the present invention is to provide a method and device for binding an RTP flow and an RTCP flow, and determine the binding relationship between the RTP flow and the RTCP flow according to the flow ID uniquely distinguishing each flow. Realized the embodiment of stream association management on the H.248 interface.

[0030] The scheme of an embodiment of the method of the present invention is as follows:

[0031] In the H.248 protocol, each stream clearly embodied on the H.248 interface is defined, and it is uniquely identified by a stream ID, which is called StreamId in the protocol. That is, both the RTP stream and the corresponding RTCP stream that is monitored will be assigned such a StreamId to identify it. The RTP stream is bound to the RTCP stream by using the StreamId uniquely distinguishing each stream.

[0032] The specific implementation process is shown in Figure 2, including the following steps:

[0033] First, according to the stream ...

Abstract

This invention relates to one real time transmission agreement and control agreement binding method and device in communication technique, wherein, the binding method comprises the following steps: according to the flow real time setting agreement transmission and monitor control agreement; expanding flow parameter and adding flow ID with binding relationship.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for binding and binding a real-time transport protocol stream and a real-time transport control protocol stream. Background technique [0002] Under the separated architecture, the main bodies of the call control plane and the bearer control plane are the gateway controller MGC and the gateway MGW respectively. Among them, MGW accepts the control of MGC, and the interface protocol between MGW and MGC is called Media Gateway Control Protocol, which is defined as H.248 series specifications in Itu-t, as shown in Figure 1. [0003] In the media gateway control protocol, the bearer resource on the gateway is abstracted as Termination (endpoint), which is identified by an ID allocated by the gateway itself, and the gateway controller uses this ID to refer to the bearer resource on the gateway and operate on it. [0004] Termination can be classified...
