    • A selective call receiver (106) has a frequency synthesizer (708) for scanning a plurality of frequencies to determine a control channel to receive a signal and a receiver (704) for receiving the signal representative of an available frequency associated with a geographic region. The signal includes a channel identifier (404), a frequency assignment (406) and an active channel indicator (408). A processor (712) associates the channel identifier (404) with the frequency assignment (406) in response to the active channel indicator (408) indicating an available frequency of the geographic region and a memory (720) stores channel identifiers (404) associated with frequency assignments (406) designating available frequencies (408). The receiver (704) receives an address (333) and the channel identifier (404) on the control channel, a decoder (714) decodes the channel identifier (404) associated with the frequency assignment (406) to determine the available frequency where a message will be transmitted and the frequency synthesizer (708) switches to the available frequency indicated by the channel identifier (404) for receiving the message.

    • A selective call receiver system includes a plurality of base sites capable of simultaneous operation. Each base site includes a transmitter and a base receiver capable of measuring the signal strength of a received signal. A controller coupled to the plurality of base sites, forwards an address to the plurality of base sites. The transmitters thereafter, simultaneously transmit the address to at least one of a plurality of selective call receivers having acknowledge-back capability. At least one of the plurality of base receivers receive an acknowledge-back signal from the at least one of the selective call receivers responding to the transmitted address. The signal strength of the acknowledge-back signal is detected by the plurality of base receivers receiving the acknowledge-back signal. The controller has a determining circuit for determining a value representing the signal strength of the acknowledge-back signal, and an encoder, coupled to the determining circuit, encoding a single copy of the message in a first format or a second format. The encoder encodes the message to derive the single copy of the message in the first format when the value determined by the determining circuit is above a predetermined level and encodes the message with an error correcting code to derive the single copy of the message in the second format when the value determined by the determining circuit is below the predetermined level. The controller thereafter forwards the single copy of the encoded message to the base site.

    • A system and method are shown for providing a fully synchronized two-way communication network having a number of transmission stations (10) and selective call receiving devices (27). Each transmission station (10) stores station identifying information and an updatable synchronization priority indicator. Periodically, each station (10) transmits a timing message that includes the station's identifying information, priority indicator, and information relating to the timing of the station's frame clock (45). When a given station receives a timing message transmitted from another station, it determines whether the other station is a direct upstream station thereof. The given station is responsive to a timing message from its direct upstream station for adjusting its frame clock (45) based upon the timing information contained in the message received from the direct upstream station. The given station thereby synchronizes itself with its direct upstream station. Each station also updates its stored priority indicator in the event that there is a change in the station's direct upstream station.
