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.
