摘要 |
Base station BS adds a base station ID for specifying itself to a signal transmitted from mobile station MS. Data distribution management unit GWS 3 of 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 GWS 3, using the area name as a search key, searches location-related information database GWS 4 for location-related information corresponding to a present location of mobile station MS and transmits the information to mobile station MS. |
