Problems solved by technology

Since VMGW1 and VMGW2 are controlled by different MGCs, the services on them may be uneven, for example, one has more calls and one has fewer
This may occur when all the time slot resources contained in the trunk circuit group 1 of VMGW1 leading to another network element are used, but the time slot resources contained in the trunk circuit group 2 of VMGW2 leading to the same network element are still When there are many timeslot resources available in the trunk circuit
At this time, although there are still a large number of time slot resources contained in the trunk circuits available in trunk circuit group 2, VMGW1 may still suffer call loss due to insufficient time slot resources contained in the trunk circuits belonging to it , which reduces the utilization rate of time slot resources included in all relay circuits belonging to the MGW

Abstract

The invention discloses a trunk circuit sharing method, a device and a system, comprising the steps of: interacting an MGC with a VMGW, and pre-reserving time slot resources contained in a shared truck circuit; the shared truck circuit is a truck circuit which is assigned to the VMGW and other VMGWs simultaneously; and the MGC occupies and uses the pre-reserved time slot resources through the VMGW to execute services. The adoption of the method, the device and the system improves the utilization rate of the time slot resources contained in the truck circuit assigned to one MGC and simultaneously reduces call loss.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a relay circuit sharing method, device and system among multiple virtual media gateways belonging to the same media gateway. Background technique [0002] In the third-generation wireless communication network (WCDMA, CDMA2000, TD-SCDMA) and the core network circuit domain of the next-generation network NGN, the idea and networking method of separating bearer and control are adopted. Its main network elements are media gateway MGW (Media Gateway) and media gateway controller MGC (Media Gateway Controller). The MGW provides media flow control functions, mainly for bearer establishment and maintenance, connection control, voice coding processing and conversion, etc. The MGC provides functions such as call control and mobility management, mainly including call control procedures, user authentication, and charging. The H.248 / Megaco protocol connects the MGC and MGW, ...
