Abstract:
A method and system for a location-based service are provided to provide each location data, including additional information generated by location measurement results from a first location measurement method and a second location measurement method in response to a service request, to a client terminal. A method for a location-based service comprises the following steps of: requesting location measurement in response to a location-based service request(S410); generating the first location data including additional information obtained based on a first location measurement method(S430); supplying the first location data to a client terminal(S440); generating second location data in which the accuracy of location measurement of the first location data is corrected by receiving the location measurement result obtained based on a second location measurement method(S450,S460); and providing the second location data to the client terminal(S470).
Abstract:
A mobile communication terminal capable of position measurement and a positioning method in the mobile terminal are provided to determine a position of the terminal by using BS(Base Station) signal information from a main BS and a neighboring BS and detailed information about the main BS and neighboring BS transmitted from a server, thus the position of the terminal can be more exactly determined. A BS information recorder(310) records BS detailed information corresponding to more than one BS. A BS information receiver receives the BS detailed information about a main BS and the more than one BS existing in an expanded area from a predetermined server. A BS information recording unit records the received BS detailed information in the recorder(310). A BS signal receiver(320) receives BS signal information at predetermined cycles or whenever being requested from the main BS. A BS information reader(330) reads the BS detailed information about the BSs, which corresponds to the received BS signal information. A positioning unit(340) determines a position of a mobile communication terminal(300) by using the received BS signal information and the read BS detailed information.
Abstract:
PROBLEM TO BE SOLVED: To provide a mobile communication terminal capable of position determination and a method of determining a position in the mobile communication terminal in which the position of the mobile communication terminal is determined, in the mobile communication terminal, by using base station signal information received from a base station. SOLUTION: A communication terminal according to the present invention includes, in one embodiment: a base station information recorder recording detailed base station information corresponding to at least one base station; a base station signal receiver receiving base station signal information from a reference base station at a predetermined interval; a base station information reader reading the detailed base station information with respect to a base station corresponding to the received base station signal information, from the base station information recorder; and a position determiner determining a position of the mobile communication terminal by using the received base station signal information and the read detailed base station information.
