Embodiment Construction

[0040] Aiming at the problem that the transfer media gateway device in the next generation network does not reserve network resources for media stream transmission when transferring calls, resulting in the problem that the service quality of transfer services between media gateway devices is not guaranteed after the media stream is transferred. The inventive transit media gateway device establishes a signaling connection with the first media gateway device and the second media gateway device through the transit call server, and forwards the media stream between the first media gateway device and the second media gateway device, thus solving the above problems .

[0041]As shown in FIG. 3 , the system for transmitting media streams in the embodiment of the present invention includes: a transit media gateway device 10 , a transit call server 20 , a first media gateway device 30 and a second media gateway device 40 .

[0042] The transit media gateway device 10 is connected with ...

Abstract

The disclosed transmission method for media flow comprises: A. the transfer-media gateway device builds signaling connection with two media gateway devices through a transfer-calling server, and creates the first / second media flow temporary terminal for the first / second gateway device; B. the transfer-media gateway device connects two temporary terminals; and C. transfer-media gateway device transmits the media flow between two gateway devices. This invention improves QoS for transferring business.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method, system and equipment for transmitting media streams. Background technique [0002] The next generation network (NGN) is a business-driven network. Due to the rapid development of IP technology, the traditional telecommunication network will gradually become the edge part of the packet backbone network. In order to support new multimedia business applications, the traditional telecommunication network will become more and more open , and introduce many new functions and physical components, NGN is the network structure that reflects this new network environment. [0003] The network service layer of NGN is mainly responsible for the relevant processing of service logic, such as service generation, service logic definition and service programming interface. The control layer mainly involves functions related to softswitch / IMS, and completes the specific execution of bu...
