Creating and recognizing user-defined locations using communication terminals
First Claim
1. A communication terminal comprising:
- at least one wireless communication interface; and
processing circuitry associated with the at least one wireless communication interface and adapted to;
monitor received signals received via the at least one wireless communication interface at least one given position associated with a defined location;
determine signal metrics for the received signals at the at least one given position;
create a signal signature based on the signal metrics for the defined location; and
assign a location identifier for the signal signature.

Abstract
The present invention allows a communication terminal to monitor signal metrics of received signals for a defined location and create a signal signature for the defined location. The defined location may be a position, an area about a position, or a defined area. After the signal signature for the defined location is created, the communication terminal will compare currently monitored signal metrics for received signals with the signal signature during normal operation. Upon returning to the location, the communication terminal will monitor signal metrics for signals being received at the location and detect when the current signal metrics correspond to the signal signature for the location. The correspondence of the new signal metrics with the signal signature indicates that the communication terminal is at a defined location.
