Patent ID: 8169927

Claim:
A configuration management method of a wireless access network in a mobile communication system comprising a wireless access network management device, a plurality of wireless network control stations and a plurality of wireless base stations, the wireless base stations each forming at least one wireless cell, the wireless network control stations each being connected to the wireless access network management device and at least one of the plurality of the wireless base stations, the method comprising: inputting input information notified from the wireless network control stations into the wireless access network management device, the input information including position information of wireless cells formed by the wireless base stations, traffic demand of each wireless cell, location registration demand of each wireless cell, handover demand with respect to each adjacent wireless cells of each wireless cell, and internal processing time required by each of the wireless network control stations for traffic processing, location registration processing, and handover processing; and selecting, by the wireless access network management device, a plurality of wireless cells to be controlled by each of the wireless network control stations so that processing loads of the plurality of wireless network control stations are leveled, based on the input information, wherein the location registration demand is an average number of times of location registration multiplied by processing time of the location registration, the traffic demand is estimated from an average value of a number of times of outgoing and incoming circuit-switched calls and packet-switched calls carried out during a certain past period in a wireless cell, and the handover demand is estimated from a number of times of handover carried out with respect to each adjacent wireless cells.
