Method for improving jump mechanism of media gateway control protocol centre

Abstract

This invention relates to a method for improving the jump system of a media gateway control center including: MGC and NG apply default value to determine heartbeat period by dynamic negotiation or configuration, the MC sends heartbeat messages to the MGC based on said period, which tests the heartbeat messages based on said period to judge the heartbeat lost between the MGC and the MG based on the response about the successful information and the test result to the MGC, which can avoid different states of the MGC and MG.

Description

technical field [0001] The present invention relates to NGN (Next Generation Network, next generation network) technology, in particular to an improved method for the heartbeat mechanism of the media gateway control protocol in the NGN network. Background technique [0002] The media gateway control protocol (including Megaco / H248, MGCP) is an important protocol in the NGN network architecture, which defines the method for the MGC (Media Gateway Controller, Media Gateway Controller) to control the MG (Media Gateway, Media Gateway). The so-called MG is defined as a device that converts the media in one network into the media format required by another network, and its function is to convert between different media formats; while the function of the MGC is to control the entire network and monitor resources and control all connections, responsible for user authentication and network security, etc. [0003] Since the media gateway control protocol is based on IP transmission, ...

AI Technical Summary

Problems solved by technology

[0008] 1. If the time set on the MG is inconsistent with the time on the MGC, it will lead to an inconsistency between the states of the two parties;

[0009] 2. Only the MG knows the state of the MGC, and the MGC does not know the state of the MG, that is, whether it is still "alive";

[0010] 3. In the case of a large number of gateways, due to the same heartbeat period, periodic IP packet peaks are prone to occur

[0013] 1. If the time set on the MG is inconsistent with the time on the MGC, it will lead to an inconsistency between the states of the two parties;

[0014] 2. In the case of a large number of gateways, due to the same heartbeat period, periodic IP packet peaks are prone to occur

[0017] 1. When the session status on the MGC and the MG are different, the status cannot be recovered in time, and even the two parties cannot detect the inconsistency of the status;

[0018] 2. In the case of a large number of gateways, due to the same heartbeat period, periodic IP packet peaks are prone to occur

[0019] To sum up, under the heartbeat mechanism in the prior art, abnormal situations still occur, because in the heartbeat mechanism of the prior art, the MGC or MG unilaterally performs the heartbeat detection control or the heartbeat detection mechanism independently controlled by each, The determination of the heartbeat cycle is determined by one party or each independently. If the time set on the MG is inconsistent with the time on the MGC, it will cause inconsistencies between the states of the MGC and the MG; and in the case of a large number of gateways, due to the The same heartbeat period is prone to periodic IP packet peaks
