Abstract
A system and method for efficiently transmitting geographical location data of mobile units is disclosed. The invention allows less than the complete geographical location data to be transmitted and reported to a locater. Using fixed geographical references, the locater then interpolates the complete geographical location of mobile units from the reported data.
Claims28
A geographical location communication system comprising:
- a plurality of references, each having reference positional data;
- a mobile unit within a region covered by a reference, the mobile unit capable of determining the geographical location (geo-location) of the mobile unit;
- and
- a locator to receive compressed geo-location data of the mobile unit and to determine the geo-location of the mobile unit by comparing the compressed geo-location data against the reference positional data of the reference covering said region.
A method for communicating geographical location comprising:
- establishing a plurality of references, each having reference positional data and an identification (ID) code;
- determining the geographical location (geo-location) of a mobile unit operating in a region;
- receiving a compressed geo-location data of the mobile unit and a reference data of a reference covering said region;
- and
- recovering the geo-location of the mobile unit by comparing the compressed geo-location data against a reference positional data, said reference positional data obtained from the received reference data.
A cellular network comprising:
- a plurality of cellular systems, each having reference positional data;
- a mobile unit within a region covered by a cellular system, the mobile unit capable of determining the geographical location (geo-location) of the mobile unit;
- and
- an application service provider (ASP) to receive compressed geo-location data of the mobile unit and to determine the geo-location of the mobile unit by comparing the compressed geo-location data against the reference positional data of the reference covering said region.
A method for communicating geographical location in a cellular network comprising:
- determining the geographical location (geo-location) of a mobile unit operating in a region;
- receiving a compressed geo-location data of the mobile unit and an identification code corresponding to a cellular system covering said region;
- recovering the geo-location of the mobile unit by comparing the compressed geo-location data against a reference positional data, said reference positional data obtained from the received identification code.
A mobile asset tracking system comprising:
- a plurality of geographical references, each having reference positional data;
- a mobile asset installed with a mobile unit operating in a region covered by a geographical reference, the mobile unit to determine the geographical location (geo-location) of the mobile asset and to report a compressed geo-location data of the mobile asset;
- and
- a locater to receive the compressed geo-location data of the mobile unit and to determine the geo-location of the mobile asset by comparing the compressed geo-location data against a reference positional data of the reference covering said region.
