Abstract

Abstract A radio communication system (1600) capable of communicating on at least two radio frequencies has a receiver (202, 206) which receives information addressed to at least one of a plurality of radio receivers (106) on a first radio frequency. A transmitter (104) transmits the information having a control signal therewith to at least one of the plurality of radio receivers (106) on the first radio frequency. A generator (102) generates the control signal for temporarily directing one or more of the plurality of radio receivers to a second radio frequency to receive address and message information. The radio receiver (106) has a receiver (804) which receives information on the first frequency, the information includes the control signal for temporarily directing the radio receiver (106) to the second radio frequency. A decoder (810) decodes the received information, and a frequency synthesizer 1802 directs the radio receiver (106) to receive information on the second radio frequency in response to the control signal. A controller (816) determines when to redirect the radio receiver (106) to return to the first radio frequency.
