Abstract

See full text

An acknowledge back (ack-back) paging system is provided which includes a central station which transmits a group of message signals to an group of ack-back pagers which are addressed as a group. The users of the group of addressed ack-back pagers indicate a response to their respective pagers thus providing ack-back data. The pagers in the group of addressed ack-back pagers then simultaneously transmit back to the central station their ack-back signals using different respective pseudorandom codes, a different pseudorandom code being dynamically allocated to each of the pagers in the group.
