Abstract
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 flow 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 co...
