Embodiment Construction

[0050] The core of the present invention is to provide a simple and efficient technical means for the MG to know the state of the MGC connected to it in real time from the application layer by expanding the corresponding monitoring mechanism in the MGCP protocol. Specifically, a corresponding inactivity timer is set on the MG, and based on the timer, it is regularly monitored whether the MGC sends a message, so as to determine the status of the MGC.

[0051] The specific implementation process of the method of the present invention is as follows: figure 2 and image 3 As shown, it specifically includes the following processing procedures:

[0052] Step 21: Set an inactivity timer on the MG independently, and its timeout period is preset as a configurable default value, namely image 3 The timer duration A in.

[0053] Step 22: When the MG successfully registers with the MGC, that is, the MGC becomes the master MGC of the MG, the MG starts the inactivity timer.

[0054] St...

Abstract

The invention relates to a realization method to monitor MGC state by MG, which comprises: the MG based on its timer real-time monitors information from MGC to determine MGC state according to acquired monitor result. This invention benefits to switch immediately to standby MGC for business when the primary MGC shows abnormal, and ensures the reliability for providing business.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing the monitoring of the state of a media gateway controller by a media gateway. Background technique [0002] MGC (Media Gateway Controller) and MG (Media Gateway) are two key components in NGN (Next Generation Network). The MGC is responsible for the call control function, and the MG is responsible for the service bearer function. The MGC and MG work together to realize the separation of the call control plane and the service bearer plane in the NGN network, and can fully share network resources, simplifying equipment upgrades and services. The extended processing, meanwhile, also greatly reduces the cost of NGN network development and maintenance. [0003] The network structure diagram of MG and MGC in NGN network is as follows: figure 1 As shown, the transmission of the media stream is performed between the MGs under the control of the MGC....
