Abstract

A location based service and system wherein a database includes customer records each mapped to customer location information. A user device launches a request to the server. The request includes user device location data, from the user device location data, a geopositional frame about the user location is calculated and used to search customer location information in the database and to retrieve customer records within the geopositional frame corresponding to the launched request.

Claims

1. A location based service comprising:

building a database including customer records each mapped to customer location information accessed by a server;

allowing a user device to launch a request to the server, the request including user device location data;

from the user device location data, calculating a geopositional frame about the user location;

using the geopositional frame to search customer location information in the database and retrieving customer records within the geopositional frame corresponding to the launched request; and

returning the retrieved customer records to the user device.

2. The method of claim 1 in which the customer location information includes a longitude hash table and a latitude hash table.

3. The method of claim 2 in which calculating a geopositional frame includes specifying the latitude and longitude of opposing corners of a polygon surrounding the user device location.

4. The method of claim 3 in which the polygon is a trapezoid.

5. The method of claim 3 in which searching customer location information in the database includes specifying longitude hash table and latitude hash table ranges based on the latitude and longitude of the opposing corners of said polygon.

6. The method of claim 1 in which the user device is configured to calculate the geopositional frame.

7. A location based service system comprising:

a database including customer records each mapped to customer location information accessed by a server;

a user device configured to launch a request including user device location data; and

a server configured to;

receive the request and user device location data,

search customer location information in the database using a geopositional frame about the user location,

retrieve customer records within the geopositional frame corresponding to the launched request, and

return retrieved customer records to the user device.

8. The system of claim 7 in which the customer location information includes a longitude hash table and a latitude hash table.

9. The system of claim 7 in which the geopositional frame specifies the latitude and longitude of opposing corners of a polygon surrounding the user device location.

10. The system of claim 9 in which the polygon is a trapezoid.

11. The system of claim 9 in which searching customer location information in the database includes specifying longitude hash table and latitude hash table ranges based on the latitude and longitude of opposing corners of said polygon.

12. The system of claim 7 in which the user device is configured to calculate the geopositional frame.
