Method for reporting information based on gateway resource group

Abstract

The invention discloses an information reporting method based on a gateway resource group, which is used in a packet network including a media gateway and a media gateway controller, comprising the following steps: dividing resources connected by the media gateway into multiple resource groups, The media gateway sends the attribute information of each resource group to the media gateway controller; after receiving the attribute information of the resource group, the media gateway controller takes different processing according to the attribute characteristics of different resource groups. The method of the invention introduces the granularity of the resource group on the MG and the MGC, effectively reducing the call loss to the whole resource adjustment caused by partial resource congestion.

Description

technical field [0001] The present invention relates to a method for processing group information report of gateway resources based on a core network, in particular to a method for reporting and processing information for a group of gateway resources in a group network. Background technique [0002] The MGC (Media Gateway Controller) and MG (Media Gateway) of the prior art are two key components in the packet network. The MGC is responsible for call control functions, and the MG is responsible for providing media resources and bearer resources. The media resources include: codec, Playback channels; bearer resources include TDM / IP / ATM bearer data channels; through this, the separation of call control plane and service bearer plane can be realized, so as to fully share network resources, simplify equipment upgrades and service expansion, and greatly reduce development and maintenance costs. [0003] The existing packet network structure such as figure 1 As shown, the MGC cont...

but in figure 2 In some cases, the resources of a certain network are only a subset of MG resources. When resource congestion occurs in this subset, OCP and CHP cannot be reported to MG.

As a result, the use of bearer network resources cannot be accurately reported to the MGC, and the MGC cannot take measures such as flow control or load transfer for this situation, which causes call loss during the communication process

[0011] In short, the media resources in the existing technology need to be divided into different subsets due to different capabilities, and the entire media resource set is still used as the granularity for reporting the usage status of bearer resources between the MG and the MGC, which will inevitably cause the MGC to fail to obtain MG resources The accurate use of the situation, and then can not control the resources reasonably, which will inevitably lead to call loss
