Patent ID: 8452298

Claim:
A method for managing interface circuits between an access network and a core network, comprising: converting in format and sending, by a control function entity within the core network, a circuit management message or a circuit management result message sent by a resource management entity within the core network to a resource coordination entity within the access network, wherein the circuit management result message sent by the resource management entity is forwarded by the control function entity to the resource coordination entity after the resource management entity implements a circuit management operation according to the circuit management message of the resource coordination entity; or converting in format and sending, by the control function entity, the circuit management message or the circuit management result message sent by the resource coordination entity to the resource management entity, wherein the circuit management result message sent by the resource coordination entity is forwarded by the control function entity to the resource management entity after the resource coordination entity implements the circuit management operation according to the circuit management message of the resource management entity; wherein the interface circuits are A interface circuits between a media gateway and a base station controller, the resource management entity is a media gateway, the control function entity is a mobile switch center server, and the resource coordination entity is a base station controller; the converting by the control function entity of a format of the circuit management message or circuit management result message sent by the resource management entity comprises: converting, by the control function entity, a circuit management message or circuit management result message that complies with a gateway control protocol into a circuit management message or circuit management result message that complies with a Base Station System Application Part (BSSAP) protocol; and the converting by the control function entity of a format of the circuit management message or circuit management result message sent by the resource coordination entity comprises: converting, by the control function entity, the circuit management message or circuit management result message that complies with the BSSAP protocol into the circuit management message or circuit management result message that complies with the gateway control protocol.
