Publication number: 20160095038Abstract: When a frequency band which can be utilized by a radio communication system is divided into multiple partial frequency bands and one or more partial frequency bands are allocated to multiple base stations, each base station reports to a control station information for receiving a signal transmitted by a terminal and a number of connected terminals for every partial frequency band. The control station determines a load of each partial frequency band based on the information received from each base station. Regarding a terminal group that performs communication utilizing the partial frequency band on which the load is generated, the control station delivers information for receiving a signal transmitted by the terminal group to each base station and instructs interference measurement of the terminal group. The control station determines necessity of a handover, a handover destination base station, and a frequency and performs a base station-led handover.Type: ApplicationFiled: September 16, 2015Publication date: March 31, 2016Inventor: Mikio KUWAHARA
