Patent ID: 8385298

Claim:
A wireless communication system comprising a plurality of base stations and a control center, the base station being configured to transmit control data used to service a mobile terminal via a control channel in a time slot selected from plurality of time slots autonomously, the control center being configured to connect to the base station via a transmission path and control the base station, the base station comprising: a notification module configured to notify the control center of output power data via the transmission path, the output power data indicating an output power of the base station; a measurement module configured to measure a reception quality of each time slot from received radio signals of control data transmitted from other base stations via the control channel; and a transmission module configured to transmit reception quality data indicating the reception quality of each time slot to the control center via the transmission path, along with data indicating the time slot selected by the base station, wherein the control center comprises: a reception module configured to receive the output power data, the reception quality data, and the data indicating the time slot from the base station; and a construction module configured to construct adjacent base station data indicating adjacency relationship between the base stations by comparing the reception quality and the output power of each of the base stations, the reception quality being obtained by converting the reception quality data based on the time slot.
