ABSTRACT:
A data communication system is provided for generating information at a source (12) and transmitting it to a non-fixed subscriber transceiver unit (STU) (14). The information is first transmitted through a public telephone network (10) to a master station (13) when the master station (13) is operable to assemble a message containing the receiver identification number (RIN) and the source identification number (SIN) along with message information. This is broadcast to geographic stations that each have a defined RF locale. Each of the geographic stations then transmits this message to the STU (14) along with specific information as to what type of RF links are available. Each of the geographic stations has a plurality of channels associated therewith that differ. The STU (14) then transmits back to the geographic station in accordance with the parameters thereof. The geographic station then establishes a communication link with the STU (14) and requests data from the master station (13), which data is then transferred to the geographic station for buffering and subsequent transfer to the STU (14).
