BASE STATION, COMMUNICATION SYSTEM, COMMUNICATION METHOD, AND PROGRAM RECORDING MEDIUM

摘要

[Problem] A mobile terminal attempting handover from a cell may execute handover to a cell managed by a base station connected to a core network other than that the current cell belongs to. In such a case, the time needed for the handover process on the mobile terminal becomes longer than the time for handover between cells belonging to the same core network. [Solution to problem] A base station includes: a storage unit that stores a list of cells neighboring to a cell managed by the base station in a manner to correlate each of the neighbor cells with an identifier for identifying a core network the neighbor cell belongs to; a reception unit that receives, from a base station neighboring to the own base station, a list stored by the neighbor base station; and a control unit that uses the received list as a list with respect to the cell managed by the own base station.
