Abstract

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 includes means for transmitting its own precalibrated 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.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 105 words
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 run-time database, comprising: a plurality of update centers at known fixed locations within the base station coverage area, each of the update centers including means for transmitting its own precalibrated location information to the location databank along with determined real-time RF measurements for the base station in cooperation with the at least one mobile unit.
Claim 2
Dependent Claim 145 words
A system as in claim 1, wherein the means for transmitting precalibrated location information to the location databank along with the determined real-time RF measurements for the base station comprises: a plurality of electronically readable GeoPads, each of the GeoPads positioned at a corresponding update center and 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 Location Adjunct Processor (LAP) in electrical communication with the base station and the location database; 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.
Claim 3
Dependent Claim 40 words
A system as in claim 2, further comprising a holding database in electrical communication with the LAP and the location databank, the holding database operative to temporarily store the RF measurements and location information and periodically update the location databank.
Claim 4
Dependent Claim 25 words
A system as in claim 2, wherein the plurality of electronically readable GeoPads are encoded with precalibrated location information through the use of bar codes.
Claim 5
Dependent Claim 19 words
A system as in claim 2, wherein the processing logic is contained within the at least one mobile unit.
Claim 6
Dependent Claim 18 words
A system as in claim 2, wherein the processing logic is contained within a Service Control Point (SCP).
Claim 7
Dependent Claim 186 words
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.
Claim 8
Dependent Claim 223 words
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.
