Acknowledge back paging system having the capability of matching variable length data messages to pager addresses

摘要

A paging terminal for transmitting address and variable length message signals to a plurality of remotely located acknowledge back and non-acknowledge back pagers, each having a unique address, includes an input for accepting variable length messages to be sent to a group of M pagers within the plurality of pagers, wherein M is an integer number. A controller orders the acknowledge back pager addresses for transmisison prior to the transmission of addresses for the non-acknowledge back pagers. A transmitter sequentially transmits the ordered addresses corresponding to the group of M pagers as an address batch during a first time period, and sequentially transmits the variable length messages for the group of pagers in a message batch including end of message markers delimiting an associated variable length message during a second time period subsequent to the first time period. The messages of the message batch are transmitted in a predetermined order bearing a known relationship to the order in which the addresses of the address batch were transmitted.
