Cellular communications tracking system using a multitude of assigned call-numbers
First Claim
1. In a telephone network system communicating to a remote location sensed location or status information concerning a mobile unit by a cellular transceiver coupled with the mobile unit, the improvement comprising:
- first means for converting said sensed location or status information at any selected instant of time to one of a multitude of assigned telephone call-numbers uniquely identifying said information at said time, and for transmitting said assigned call-numbers over said network; and
second means for receiving said assigned call-numbers and to extract therefrom said location or status information;
with said second means extracting said location or status information before any telephone call-connection from said first means to said second means is completed.

Abstract
A telephone network system for communicating location or status information concerning a mobile unit by cellular telephone coupled with the mobile unit in which sensed location or status information at any selected instant of time is converted to one of a multiple of coded, assigned telephone call-numbers uniquely identifying such information at that time, where the assigned call-number is transmitted over the network, and where the assigned call-number is received at a remote location, with the location or status information being extracted before any telephone call-connection from the mobile unit to the remote location is completed. The coded, assigned telephone call-numbers are reserved by the system operator from the telephone company serving the area of the remote location, and extracting the location or status information before any telephone call-connection is completed saves the costs to an end user of the mobile unit associated with a conventional telephone call-connection.
