Embodiment Construction

[0013] The specific implementation of the technical solution will be described in detail below in conjunction with the accompanying drawings.

[0014] figure 1 It is a flow chart of the method embodiment of the present invention, describing the process of using the H.248 / MEGACO protocol command to make the media gateway controller obtain the media gateway capability set. After the media gateway MGW is successfully registered on the media gateway controller MGC, the MGC can send the audit capability (AuditCapability) command to obtain the capability set that the MGW can support, and when the capability of the MGW changes, it will notify the MGC through the service change (ServieChange) command , the MGC obtains the updated capability set of the MGW.

[0015] Such as figure 1 As shown, the method embodiment of the present invention comprises the following steps:

[0016] Step 10: After the MGW is powered on, the MGW initiates a service change registration command to the MGC, ...

Abstract

A method that the ability of getting media gateway by the media gateway controller, which uses to control the communication system and the loading separating technology. That is: the media gateway controller sends the auditing ability order to get the current supportable ability collection of the media gateway after the media gateway login successful in the media gateway, the media gateway controller get the renewing ability collection of the media gateway when the ability of the media gateway changes and impart the media gateway controller by the service changing order. The invention is thatthe media gateway controller can get the ability collection of the media gateway accurately, the media gateway controller can judge the ability of the media gateway accurately in the call, avoid the unnecessary calling loss.

Description

technical field [0001] The invention relates to the control and bearer separation technology of the communication system, in particular to the H.248 protocol and the MEGACO protocol. Background technique [0002] With the increasingly wide application of communication systems in various fields such as economy and social life, communication system technology itself is also developing rapidly. Whether it is the transformation of the current fixed network or the mature and perfect third-generation mobile communication system, technology The development of the Internet is increasingly meeting the needs of users for communication systems. At present, the industry generally agrees that the next-generation communication system will be a network in which control and bearer are separated. Its basic feature is to separate the traditional control and call centralized equipment into MGC (Media Gateway Controller, Media Gateway Controller) and MGW ( Media Gateway, media gateway) two par...
