Estimating whether or not a wireless terminal is in a geographic zone using pattern classification

摘要

A method and apparatus are disclosed for estimating whether or not a wireless terminal is in a geographic zone. The illustrative embodiment employs a pattern classifier that is trained on traits of electromagnetic signals at various locations. A computer-executable program is then generated based on the trained pattern classifier, and the program is installed and executed on a subscribed identity module of the terminal.

主权项

1. A method comprising:
training a pattern classifier on a plurality of input-output mappings, resulting in a trained pattern classifier, wherein each of said input-output mappings comprises
(i) an input that is based on one or more traits of one or more electromagnetic signals at a respective geo-location, and(ii) a Boolean output that indicates whether the respective geo-location is inside a geographic zone Z; and generating a computer-executable program based on the trained pattern classifier, wherein said computer-executable program is executable on a wireless terminal to correct measurements made by the wireless terminal and to estimate whether said wireless terminal is inside said geographic zone Z, and transmitting said computer-executable program to said wireless terminal via a wireless switching center.
