Method and apparatus for mobile terminal user-oriented precise location-based information services
First Claim
1. The present invention provides a precise location-based information service method for a user of a mobile terminal, including:
- acquiring at least two types of positioning references based upon a positioning service request from the user, wherein one type of positioning reference includes a base station reference indicating base station coordinates of a base station in a mobile phone network providing services to the mobile terminal, and the base station coordinates are used as positioning information of the mobile terminal, and another type of positioning reference includes Wireless Fidelity (WIFI) information or Global Positioning System (GPS) information;
establishing correlation relationships among the positioning references based on the acquired positioning references; and
performing integrated positioning and cross-validation on a precise location of the user based on the correlation relationships to determine final positioning service information,wherein performing cross-validation further includes;
correcting the base station coordinates using the Global Positioning System (GPS) information and the Wireless Fidelity (WIFI) information;
correcting the WIFI information using GPS coordinates information; and
correcting the WIFI information based on WIFI adjacent relationships,wherein correcting the base station coordinates using the GPS information and the WIFI information further includes;
within a coverage area of the base station, determining a region where the user frequently appears by using the GPS information and the WIFI information;
calculating a center point of region; and
correcting the base station coordinates as coordinates of the center point of the region.

Abstract
The present invention provides a precise location-based information service method and apparatus for mobile terminal browser users. The method includes: acquiring at least two types of positioning references based upon a positioning service request from a user; establishing correlation relationships among the positioning references based on the acquired positioning references; and performing integrated positioning and cross-validation on a precise location of the user based on the correlation relationships to determine final positioning service information. This invention can implement precise location-based services (LBS) and precise Point of Interest (POI) push service by analysis and extraction of the user'"'"'s location information and behavioral data acquired and accumulated with the user'"'"'s consent. This satisfies the needs of the mobile phone browser user for precise LBS and personalized nearby information service.
