Patent ID: 8660090

Claim:
A communication control apparatus for controlling communication of a mobile communication system including a plurality of cells formed by a plurality of base stations, comprising: a communication interface; and a processor configured to specify an identifier for wireless communication that differs from any of wireless communication identifiers already allocated to mobile devices existing within any of cells in a cell group constituted by a first cell and one or more cells partly overlapping with the first cell, and to allocate the specified wireless communication identifier to a mobile device existing in the cell group; and to control the communication interface to transmit the identifier allocated by an allocator to the mobile device; wherein, when the mobile device is to connect to base stations of different cell groups and communicate with the base stations simultaneously, the allocator selects one identifier in an identifier group and allocates the mobile device the selected identifier which is not used in the different cell groups and which can be used in common in the different cell groups; the identifier group including a plurality of identifiers being capable of allocating to mobile devices connected to a same cell.
