CONTROLLING APPARATUS, METHOD OF ALLOCATING RADIO CHANNELS, PROGRAM AND STORAGE MEDIUM

摘要

A controlling apparatus that allocates radio channels in a first radio communication system, and a method of allocating radio channels. The apparatus acquires information for distinguishing channels of a first type shared with a second radio communication system or shared by a control channel of the first system and determines, in accordance with the information, whether a first condition including that an occupation ratio of the one or more channels of the second type does not exceed a first threshold is satisfied. The apparatus allocates a channel of the second type when the first condition is satisfied, and a channel of the first type when the first condition is not satisfied.
