Abstract:
1. A handover method comprising: prior to a handover; multicast-sending, by at least one first wireless base station on an access network, access network interface information at a specific radio frequency toward a wired backbone network, the access network interface information including respective location information for the at least one first wireless base station; determining, by a second wireless base station, a value for a distance from the at least one first wireless base station to a second wireless base station, using the respective location information included in the access network interface information received via the backbone network; and generating, by the second wireless base station, neighbor access network information according to the respective determined value for the distance from the at least one first wireless base station to the second wireless base station; when the wireless base station decides to perform handover for a mobile terminal: notifying, by the second wireless base station, a handover notification containing at least a part of the neighbor access network information, and selecting, by the mobile terminal, a destination wireless base station based on the handover notification and communication quality; wherein the determining, by the second wireless base station, includes determining whether the respective determined value for the distance of each of the at least one first wireless base station to the second wireless base station is within a range of a predetermined distance on the basis of the respective location information, to handle one or more of the corresponding access network interface information of the at least one first wireless base station within the range of the predetermined distance as the respective neighbor access network information; and wherein the selecting, by the mobile terminal, includes selecting an wireless base station having a shortest respective determined distance and better communication quality as the destination wireless base station on the basis of the handover notification.
