System and method for a wide area wireless personal communication system incorporating advanced messaging
First Claim
1. A personal access communications system for implementing full two way voice and data service in a voice service area and two way messaging in areas outside the voice service area, the personal access communications system comprising:
- a plurality of radio ports for implementing the full two way voice and data service in the voice service area, the radio ports transmitting voice and data signals on a first communication channel;
at least one portable transceiver unit adapted to receive and transmit voice and data in addition to receiving and responding to paging signals; and
a plurality of long range pagers for transmitting and receiving paging signals wherein the paging signals are integrated into the voice and data transmission format of the personal communication system, the long range pagers defining a paging service area outside of the voice service area wherein the long range pagers share a second communication channel different from the first communication channel.

Abstract
A system and method for integrating advanced messaging capabilities in a wide area wireless personal communications system is provided. The system includes personal transceiver units capable of communicating with one or more of a plurality of long range pagers. The transceiver and long range pager use existing frequencies and formats of the wireless personal communications system. The method provides for registering a personal transceiver in a two way messaging service area of the wireless personal communications system.

12. A wide area wireless personal communication system incorporating advanced messaging capability comprising:
-
at least one short range transceiver having an operating range defining a voice service area for providing voice and data communication to a user having a personal transceiver unit, the at least one short range transceiver operating on a first communication channel;
a two way messaging service area for providing advanced messaging services to users via a plurality of long range pagers, the long range pagers operating on a second communication channel different from the first communication channel, the long range pagers sharing the second communication channel. - View Dependent Claims (13, 14)
a forward error correction encoder in communication with a Hadamard transform encoder;
said Hadamard transform encoder in communication with a parallel-to-IQ converter; and
a bit spreader coupled to a pseudo-random number generator for receiving an I and a Q serial information stream from the parallel-to-IQ converter.

15. A method of registering a personal transceiver unit in a two way messaging service area of a wireless personal communications system comprising the steps of:
-
monitoring a SBC broadcast in a voice service area with the personal transceiver unit;
switching to a predetermined paging frequency if no SBC is detected;
acquiring a long range pager broadcasting on said paging frequency by (a) searching for a strongest received long range pager signal;
(b) synchronizing the transceiver unit to a long range pager having the strongest signal, and (c) reading a transmitter ID for the long range pager having the strongest signal; and
registering a location of the personal transceiver unit with the wireless personal communications system via the long range pager. - View Dependent Claims (16, 17, 18)
