Abstract

The invention provides a method for processing media stream and a media gateway. The method comprises the following steps of determining encoding / decoding information of two endpoints of the media stream; and processing the media stream according to the encoding / decoding information of the two endpoints if the encoding / decoding information of the two endpoints does not belong to an encoding / decoding capability set supported by the media gateway, wherein the processing includes unvarnished transmission processing. Through the embodiment of the invention, the calling success ratio can be increased and the calling loss can be reduced.

Description

technical field [0001] The invention relates to network communication technology, in particular to a media stream processing method and a media gateway. Background technique [0002] In the next generation network (Next Generation Network, NGN) and IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) network, control and bearer have been separated, and two important devices are the media gateway controller of the control plane and the bearer plane media gateway. During the call establishment process, the media gateway controller controls the call establishment and controls the media gateway to allocate media bearer resources for this call through the H.248 protocol; The codec type determines whether to add a transcoder resource to complete the codec conversion of the media stream. [0003] There is a supported codec capability set in the media gateway, and the media gateway cannot encode and decode codecs outside the capability set. After the media gateway is controlled...
