Problems solved by technology

But in fact, due to the failure of the connection between MGW-1 and the wireless access side equipment, it is impossible to complete the task of this call, which will inevitably lead to the loss of this call
[0010] It can be seen that in the prior art, there is no method for the MGC to determine the MGW used for bearer, which can avoid call loss

Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The basic idea of ​​the present invention is: the MGC determines an MGW with a normal connection state according to the connection state table used to record the connection state of the MGW, and uses the MGW with a normal connection state as the MGW for bearer.

[0029] In the present invention, a connection status table for recording the connection status of the MGW needs to be set in the MGC in advance, all MGWs connected to the MGC and the wireless access side equipment at the same time are recorded in the connection status table, and the initial value of the connection status is set to as normal.

[0030] In the present invention, the MGW recorded in the connection state table will judge in real time whether the connection stat...

Abstract

A method of using media gateway controller to confirm gateway for carrying load includes setting connection state table for recoding connection state of MGW in MGC first, judging whether connection state of itself to network entity directly connected with selectable load-carry path is changed or not by MGW in real time, reporting variation situation of connection state to MGC if it is and updating connection state table, querying connection state tale and confirming one MGW with proper connection state as MGW used for carrying load when message of call setting-up request is received by MGC.

Description

technical field [0001] The present invention relates to the technology of establishing the bearer, in particular to the method for the media gateway controller to determine the media gateway used for the bearer. Background technique [0002] Currently, in the mobile network that introduces the softswitch network architecture, the circuit domain core network is separated into a bearer plane and a control plane. Wherein, the bearer plane is composed of a media gateway (MGW), and the control plane is composed of a media gateway controller (MGC). The interface between the MGC and the MGW is the Mc interface, and the interaction is performed according to the H.248 protocol. [0003] In an actual mobile communication network, one or more MGWs can be connected to both the MGC and the base station control equipment, and the formed network is generally called a MINI-IU-FLEX network. [0004] figure 1 It is a typical MINI-IU-FLEX network structure diagram. Such as figure 1 As sho...
