Abstract:
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, and wherein 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, wherein said priority computation section counts the number of reports of measurement information of said neighbor cells in a predetermined counting period and computes the priorities of the neighbor cells based on the counted number of reports, wherein said priority computation section computes a weighted average value of the number of reports for said neighbor cells in an elapsed time after a tabulation period and computes the priorities of the neighbor cells based on the weighted average values.
