RADIO COMMUNICATION SYSTEM, NEIGHBOR CELL LIST OPTIMIZING SYSTEM, BASE STATION, AND NEIGHBOR CELL LIST UPDATING METHOD
First Claim
1. A radio communication system, comprising:
- a mobile terminal;
a base station that manages a cell to which said mobile terminal establishes a connection and that is provided with a neighbor cell list to which specific neighbor cells, that are candidates of a handover destination cell for said mobile terminal; and
a neighbor cell list updating unit that updates the neighbor cell list provided in said base station,wherein said mobile terminal measures radio communication qualities of neighbor cells that are in the vicinity of said cells and reports measurement information that represents radio communication qualities of the neighbor cells in which the measured radio communication qualities exceed a predetermined threshold to said base station, andwherein said neighbor cell list updating unit includes;
a priority computation section that computes priorities of said neighbor cells to be registered to said neighbor cell list based on said measurement information reported to said base station; and
a neighbor cell list updating section that registers neighbor cells to said neighbor cell list in descending order of the neighbor cells'"'"' priorities that are computed by said priority computation section up to an upper limit of radio cells that can be registered to said neighbor cell list.

Abstract
A neighbor cell list optimizing system according to the present invention is a neighbor cell list optimizing system that updates a neighbor cell list that is provided in a base station that manages a cell to which a mobile terminal establishes a connection and to which specific neighbor cells that are candidates of a handover destination cell for said mobile terminal of neighbor cells that are in the vicinity of said cell are registered, comprising: priority computation section that computes priorities of said neighbor cells to be registered to said neighbor cell list based on measurement information that represents radio communication qualities of neighbor cells in which the measured radio communication qualities exceed a threshold; and neighbor cell list updating section that registers neighbor cells in descending order of the priorities up to an upper limit of radio cells that can be registered to said neighbor cell list.
