  • System and method for providing a geographic location of a mobile telecommunications unit
    Patent number: 6091957
    Abstract: A system and method is described herein which provides an originating telecommunications unit with the geographic location of a mobile telecommunications unit without actually placing a call to, or receiving a call from, the mobile unit. The originating unit provides a service platform with an authorization code and the telephone number, or other identification, of the mobile unit to be located. The service platform then initiates a location program which uses various geographic location methods to provide the originating unit with the location of the mobile unit, without the user of the mobile unit becoming aware that the location of the mobile unit is being determined.
