Abstract
A method of selecting allocated communication channels for use by a cellular auxiliary personal communication system (CAPCS) comprising periodically collecting relative signal strength indication (RSSI) measurements for all allocated communication channels, periodically determining the estimated expected probability of non-interference for each allocated communication channel based on the relative signal strength indication measurements and selecting an available allocated communication channel having the highest estimated expected probability of non-interference for use by the CAPCS system. The relative signal strength indication measurements are made on the allocated communication channels by measuring the signal on the allocated communication channel when no call is being carried by the CAPCS on that channel. The estimated expected probability of non-interference for each allocated communication channel also takes into consideration the received signal strength indication measurements on adjacent allocated communication channels and allocated communication channels in the same group.
