Problems solved by technology

[0006] The above-mentioned method for realizing the time synchronization between the media gateway device and the network needs to implement the NTP or SNTP protocol on the media gateway device, which will inevitably increase the system overhead of the media gateway device
At the same time, it is also necessary to add an NTP / SNTP server (NTP / SNTP server) to the network, which will increase the network cost and the system complexity of the network
Moreover, NTP / SNTP server configuration needs to be performed on the media gateway device, which greatly increases the workload of network operation and maintenance.

Embodiment Construction

[0043] The core of the present invention is to directly synchronize the system time of the media gateway device through the MGC (Media Gateway Controller) to avoid implementing the NTP / SNTP protocol in the network to realize the synchronization of the whole network and reduce the complexity of networking.

[0044] In order to have a further understanding of the present invention, the specific implementation of the method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] The method of the present invention is suitable for media gateways running MGCP (media gateway control protocol), H.248 and other signaling protocols. The following will take a media gateway running the MGCP protocol as an example to describe the specific implementation of the method of the present invention.

[0046] In the specific implementation process of the present invention, MGC, that is, the SoftSwitch (soft switch) system time is used as ...

Abstract

The invention discloses a media gateway realizing synchronization method and device of communication system, which is characterized by the following: the media gateway gets time synchronizing parameter from media gateway controller MGC and realizes synchronization with network time according to the get time synchronizing parameter. The invention saves network time server and reduces complexity of NGN network and gateway system.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing synchronization of media gateways in a communication system. Background technique [0002] With the continuous maturity of NGN (Next Generation Network) technology, voice bearer on IP network has been more and more widely used. figure 1 It is a simple single-domain networking diagram of NGN network applied to voice service. Only one MGC (Media Gateway Controller) is shown in the figure, and there may be multiple MGCs in actual networking applications. [0003] exist figure 1 Among them, IAD (Integrated Access Device), AMG (Access Media Gateway) and TMG (Trunk Media Gateway) all play the role of media stream conversion, that is, they are used to encode the user's voice signal into G.711, G .729 or G.723.1 voice frames that can be transmitted over IP. At the same time, it is also used to decode G.711, G.729 or G.723.1 voice frames on the IP ne...
