Abstract
In a multiple mode communication system (29), a radio communication device (22) selectively communicates, using a common pool of channels (42), through a cordless base station (30) and a cellular network having a plurality of cellular base stations (24). The radio communication device (22) determines and stores local station identifiers (88) for the cellular base stations (24) which are broadcasting message streams (48) over control channels (46) in a cordless radio coverage area (26) of the radio communication device (22). The radio communication device (22) transmits a message to the cordless base station (30) when a detected cellular base station identifier (51) matches one of the determined local station identifiers (88). The radio communication device (22) is prevented from transmitting a message when the detected cellular base station identifier (51) matches none of the local station identifiers (88).
