ABSTRACT:
Base station BS adds a base station ID for specifying itself to a signal transmitted from mobile station MS. Data distribution management unit GWS3of gateway server GWS extracts the base station ID added to a GET request and reads out an area name corresponding to the base station ID from area name conversion table TBL. Data distribution management unit GWS3,using the area name as a search key, searches location-related information database GWS4for location-related information corresponding to a present location of mobile station MS and transmits the information to mobile station MS.
