System and method for updating a location databank
First Claim
1. For use in cooperation with a wireless communication system, including a base station in electrical communication with at least one mobile unit within a corresponding coverage area, and a location databank operative to store real-time RF measurements for the base station, including its link budget, a system for updating the location databank, comprising:
- a plurality of update centers at known fixed locations within the base station coverage area, each of the update centers including an electronically readable GeoPad encoded with the precalibrated location information for that center;
an electronic reading device in electrical communication with the at least one mobile unit for decoding the encoded location information at each of the GeoPads;
a control unit in electrical communication with the base station;
a Location Adjunct Processor (LAP) in electrical communication with the control unit and the location databank; and
processing logic in electrical communication with the at least one mobile unit, the processing logic operative to obtain the RF measurements at each of the GeoPads and initiate a call to the LAP to transmit said measurements to the location databank along with the decoded location information.

Abstract
A system and method for updating a location databank of a personal location system which is directed for use in a wireless communication system. A plurality of update centers are provided at known fixed locations within a base station coverage area. Each of the update centers is operative to transmit its own pre-calibrated location information to a location databank along with real-time RF measurements for the base station. Each of the base stations is provided in electrical communication with a location adjunct processor which, in turn, is provided in electrical communication with the location databank and the public switched telephone network. Processing logic is operative to obtain the desired RF measurement at GeoPads which are provided in electrical communication with each update center. Processing logic is further operative to initiate a call to the LAP in order to transmit the measurements to the location databank along with the decoded location information so as to provide periodic updating.

2. For use in cooperation with a wireless communication system, including a base station in electrical communication with at least one mobile unit within a corresponding coverage area, and a location databank operative to store real-time RF measurements for the base station, including its link budget, a method for periodically updating the location databank, comprising:
-
providing a plurality of update centers at known fixed locations within the base station coverage area, each of the update centers including an electronically readable GeoPad encoded with the precalibrated location information for that center; providing an electronic reading device in electrical communication with the at least one mobile unit; decoding the encoded location information at one of the GeoPads through the use of the electronic reading device; providing processing logic in electrical communication with the at least one mobile unit; providing a control unit in electrical communication with the base station; providing a Location Adjunct Processor (LAP) in electrical communication with the control unit; providing a holding database in electrical communication with the LAP and the location databank; and making real-time RF measurements at one of the GeoPads and initiating a call to the LAP in cooperation with the processing logic to transmit the measurements along with the decoded location information to the holding database for temporary storage, whereby to provide said periodic updating of the location databank.
