ABSTRACT:
A personal communication system (100) having power control provided by a radio port control unit (122), provides for portable radio controlled optimum base station selection. Multiple base stations 102, 124, and 130 transmit channel signals including a code word which indicates the transmit power level of each transmission. A portable radio 120 measures the received signal strength (RSS) of each of the channel signals transmitted from the base stations and also receives the coded power levels of each transmission. The portable (120) then calculates an adjusted received signal strength (ARSS) value for different channels from different base stations. The portable (120) then compares the ARSS values to determine the optimum base station to communicate with for portable controlled handover, local registration, and link set up.
