Method of generating control signals based on location of radio terminals
First Claim
1. A method of generating a control signal comprising:
- determining the location of a first mobile radio terminal, wherein the first mobile radio terminal has been deactivated;
determining the location of a second mobile radio terminal, wherein the second mobile radio terminal comprises a smart card that serves as a key to activate the first mobile radio terminal;
comparing the locations of the first mobile radio terminal and the second mobile radio terminal; and
generating a control signal in response to comparing the locations of the first mobile radio terminal and the second mobile radio terminal, wherein the control signal activates the first mobile radio terminal if the locations of the first mobile radio terminal and the second mobile radio terminal are within a specified distance.

Abstract
A method of generating a control signal to enable or inhibit a wide variety of applications is provided. The method generally includes the steps of determining the location of a first mobile radio terminal, determining the location of a second mobile radio terminal, comparing the locations of the terminals, and generating a control signal based upon the comparison. The control signal may be generated if the first and second mobile radio terminals are within a specified distance of one another. Alternatively, the control signal may be generated if the first and second mobile radio terminals are separated by at least a specified distance from one another. Additionally, the control signal may be generated if it is determined that the first mobile radio terminal is at a first specified location and the second mobile radio terminal is at a second specified location spacially separated from the first specified location. Further, the control signal may be generated if the first and second mobile radio terminals are at specified locations at a preselect time.
