Problems solved by technology

[0007] However, considering the actual needs, sometimes it may be necessary to restrict the chat between some users, for example, for figure 1 , it is necessary to restrict the conversation between user A and user B, and user C can freely chat with user A and user B, namely: Ao=Ci, Bo=Ci, Co=Ai+Bi
For this requirement, MGCP in the current prior art cannot be realized, because the existing MGCP technology does not provide a method for controlling the transmission direction of media streams between connections
[0008] At present, although another media gateway control protocol called H248 protocol provides a method to control the transmission direction of media streams between connections, since MGCP has been widely used, if the MGCP protocol is replaced by the H248 protocol in the MGC and MG equipment, then Will pay a high cost for this, which is not desirable for network operations

example 1

[0074] Example 1: According to the actual situation, it is necessary to restrict the conversation between user A and user B, while user C can freely chat with user A and user B, that is, Ao=Ci, Bo=Ci, Co=Ai+Bi, Then it is necessary to set the Topology (topology) relationship between the connections on the conference bridge endpoint as: Isolate(ConnId1, ConnId2), bothway(ConnId2, ConnId3), bothway(ConnId1, ConnId3), such as Figure 8 As shown, in this way, the conference bridge endpoint will transmit the media stream sent by each connection according to the configured Topology (topology) relationship, so that the transmission direction of the media stream under the MGCP-based endpoint can be adjusted according to the needs of the actual situation. control.

example 2

[0075] Example 2: It is necessary to realize that user A can hear user B's voice at the endpoint of the conference bridge (that is, user A can receive user B's media stream), but user B cannot hear user C's voice, and user C and user B can talk ( That is, the media stream between user C and user B can be transmitted bidirectionally), user C can hear the voice of user A, but user A cannot hear the voice of user C, that is, Ao=Bi, Bo=Ci, Co=Bi+Ai , at this time, you need to set the Topology (topology) relationship between the connections on the endpoint as: oneway(ConnId2, ConnId1), bothway(ConnId2, ConnId3), oneway(ConnId1, ConnId3), such as Figure 9 As shown, it can be seen that the transmission direction of the media stream marked in the figure is the required transmission direction of the media stream.

example 3

[0076] Example 3: This example will explain how to modify the media stream transmission direction setting for the conference bridge endpoint on the MG, that is, how to control and operate the Topology (topology) relationship set for each connection on the MGCP-based endpoint. Still based on the example of the three-party call mentioned above, the connection 1, connection 2 and connection 3 created on the conference bridge endpoint are at the beginning of creation, and the media stream transmission direction between each connection is set or the default is set to bothway. Limit the conversation between user A and user B, and user C can freely chat with user A and user B, that is, the required Ao=Ci, Bo=Ci, Co=Ai+Bi requirements, assuming the expansion of the definition The name of the MGCP data packet is: ConnsTp; the name of the signal is: ModTp; the name of the signal parameter is: Tp; then the control signaling issued by the MGC is: S: ConnsTp / ModTp(top=Isolate(ConnId1, ConnI...

Abstract

The method includes following step: the transmission direction of media flow under the control terminal based on MGCP is set, the above terminal controls transmission direction of media flow according to the set transmission direction of media flow. The invention implements the control of transmission direction of media flow between any connections in terminal in MOCP.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for controlling the transmission direction of a media stream under an endpoint. Background technique [0002] MGCP (Media Gateway Control Protocol) is a master-slave control protocol widely used in communication networks. In the network, MGC (Media Gateway Controller) controls and manages MG (Media Gateway) based on MGCP. The voice communication is realized between each MG, and the MGC mainly completes the service control function, that is, the formulation of various services can be completed on the MGC side, while the MG mainly completes the media stream processing function. [0003] MGCP adopts a connection-based call model composed of endpoints and connections, and uses calls to manage connections. Multiple connections can be created under one MGCP-based endpoint. Usually, one connection is established for each user under the endpoint, that is, one user ...
