Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to the following embodiments.

[0049] The embodiment of the present invention defines the associated office route and gateway as an office route gateway pair, a certain office route may be associated with multiple MGWs, and a certain MGW may also be associated with multiple office routes. The embodiment of the present invention also defines the associated IP trunk group and gateway as an IP trunk group-gateway pair, a certain IP trunk group can be associated with multiple MGWs, and a certain MGW can also be associated with multiple IP trunk groups. The embodiment of the present invention selects the corresponding outgoing MGW based on the office-to-office gateway pair or the IP trunk group gateway pair, and performs QoS sampling, and decides whether to carry out the call volume of the office-to-office gate...

Abstract

This invention provides a method, a device and a system for selecting route and controlling flow volumes, in which, the method includes: the local office MGC configures a gateway-to-the-board in advance in the opposite MGC board to select a gateway allowing setting up calls to send a request for setting up loading to the local MGW in the board and sets up call with the opposite MGC and decides if it controls the call volume to the board according to the reported information of the local MGW.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method, device and system for routing and flow control. Background technique [0002] As the core technology of NGN (Next generation network, next generation network), softswitch provides call control and connection control functions for NGN services with real-time requirements. Under the softswitch architecture, the core network realizes the separation of bearer and control. The management of the call state and the control of the bearer resources of the media gateway are realized through the MGC (Media Gateway Controller) to complete the call control function, while the MGW (Media Gateway Controller) Gateway, media gateway) is used to implement bearer, complete the establishment, modification, release and resource management of media streams. The MGC controls the MGW to establish a bearer through a media gateway control protocol (such as H.248). The current traditional t...
