A METHOD, EQUIPMENT AND SYSTEM FOR PATH SELECTION AND FLOW CONTROL

摘要

A method, equipment and system for path selection and flow control are in the network communication field. In order to solve the problem that the QoS may be misjudged and the call completing rate may be affected when the path selection and flow control are preformed in the prior art, the invention provides a method for path selection and flow control. The method includes: a station gateway pair which is allowed to create the call is selected from the preset station gateway pairs and a call is created; the preset station gateway pairs include the station gateway pair which is preset according to the station direction from the local station gateway controller to the opposite station media gateway controller; after the call is created, it is decided that if the call flow of the station gateway pair will be controlled according to the reported QoS information of the station gateway pair. The invention also provides an equipment and system for path selection and flow control. By using the invention, the QoS is sampled based on the station gateway, and the path selection and flow control are performed according to the QoS sampling information. Therefore, the quality of service is ensured and the call completing rate of the system could be improved.
