Interconnection method for base station and access network system

The invention provides an interconnection method for a base station and an access network system. The interconnection method comprises the following steps of: receiving a server request message transmitted by source user equipment by a source base station, wherein the server request message contains the requested service information and identification information of target user equipment; and establishing an interconnected straight-through channel according to an interconnection demand parameter corresponding to the service information and a target base station where the target user equipment is positioned by the source base station so as to transmit service data interacted between the source user equipment and the target user equipment on the interconnected straight-through channel. In the interconnection method for the base station and the access network system provided by the invention, the source base station can establish the interconnected straight-through channel meeting the interconnection demand parameter with the target base station according to the interconnection demand parameter, thereby ensuring that the service data loss or communication interruption is avoided as much as possible when the source UE and the target UE carry out service data interaction on the interconnected straight-through channel and further the quality of network services is improved.
