Title:
WIRELESS COMMUNICATION SYSTEM, ADJACENT CELL LIST OPTIMIZATION SYSTEM, BASE STATION, ADJACENT CELL LIST UPDATE METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2011/158501
Kind Code:
A1
Abstract:
A first mobile terminal group includes first measurement information transmission means for measuring radio quality of a second cell and transmitting the measurement information to a first base station, and a second mobile terminal group includes second measurement information transmission means for measuring radio quality of a first cell and transmitting the measurement information to a second base station. An adjacent cell optimization system includes measurement information collection means for collecting the measurement information of the first and second cells; reliability degree evaluation means for performing processing for evaluating the reliability degree of the measurement information of the second cell; priority degree calculation means which, when the reliability degree is at a predetermined threshold or below, calculates a priority degree for registering the second cell in the adjacent cell list of the first cell on the basis of the measurement information of the first cell; and adjacent cell list update means for determining an adjacent cell to register on the basis of the priority degrees and performing control for updating the adjacent cell list.
