METHOD FOR LOCATION-BASED ALERT SERVICES IN WIRELESS COMMUNICATION ENVIRONMENT

摘要

The present invention is to minimize, location query count relates to a device and a method for providing a location-based alarm Service indicating the fact, if it is located within a specific user and a certain area by using a mobile communication terminal and the mobile communication network It provides an apparatus and method for improved location lookup method according to the conventional constant period of time. The invention then with the dynamic configuration of the MBR (minimum bounding rectangle) on the way, and the movement position using a increase, decrease of the time interval for the next location requested by the ratio of the moving distance as a method for minimizing the number of times a location request, increase of the time interval for the position inquiry, the location-based service alert apparatus and method which is characterized in that it comprises a method for the reduction. By decreasing the location query cost by applying the method and apparatus to minimize the position number of requests for position-based alert service provider of the present invention dramatically can improve the user service utilization and the service satisfaction.
