Abstract:
PROBLEM TO BE SOLVED: To optimally control power and other parameters, in a two-way communication system, by utilizing a GPS receiver. SOLUTION: A selective-call transceiver (20) in a messaging system having a plurality of transmitters (90, 94, 99), is constituted of a receiver module (26), a transmitter module (22) coupled to the receiver module and a controller coupled to the receiver module and the transmitter module for controlling the operation of the selective call transceiver. Additionally, the selective-call transceiver also comprises a GPS receiver (24), coupled to the controller for receiving GPS information, wherein the controller uses the GPS information to assist in the control of functions selected from among a group, consisting of transmitter power control, site selection switching, sub-zone selection switching, forward error correction, retry transmission decisions, Doppler-frequency shift, synchronization, and frequency scanning and selection.

A selective call transceiver (20) in a messaging system (100) having a plurality of transmitters (90, 94, 99), comprises a receiver module (26), a transmitter module (22) coupled to the receiver module and a controller (28) coupled to the receiver module and the transmitter module for controlling the operation of the selective call transceiver. Additionally the selective call transceiver comprises a GPS receiver (24) for receiving GPS information and coupled to the controller, wherein the controller uses the GPS information to assist in the control of functions selected from the group consisting of transmitter power control, site selection switching, sub-zone selection switching, forward error correction, retry transmission decisions, Doppler frequency shifting, synchronization, and frequency scanning and selection.
Abstract:
A wireless communication system conducts (402) communications between a fixed portion (102) of the wireless communication system and a portable subscriber unit (122) carried by a user; and records (404) a relevant aspect of the communications, thereby producing recorded information. The system determines (405) a current time of day and a current position of the user and makes (406) a comparison of the recorded information with the current time of day and the current position of the user to determine whether an alert is necessary, and generates (412) the alert when the comparison determines the alert is necessary.
Abstract:
A wireless communication system receives (402) a communication specifying a portable subscriber unit (122) for which the communication is intended, and further indicating an originator location at which an originator of the communication is positioned. The system determines (404) a recipient location at which the portable subscriber unit is positioned. The system then calculates (406) a distance between the originator location and the recipient location, and routes (412) the communication to the portable subscriber unit when the distance meets a distance criterion.
