摘要 |
An ID signal indicating a base station ID is broadcasted by a base station 21 sited in a specific area of a location registration area. When receiving the ID signal, a mobile station 10 located in the radio zone of the base station 21 transmits to the base station 21 a location registration request signal including the base station ID and a mobile station ID. The base station ID and the mobile station ID are registered in a home memory 23 as narrow-area location registration information. An IP server 40 a acquires location related information from a location-related information data base 41 a and transmits it to a gateway server 25 . The gateway server 25 specifies a destination of transmission for the received location related information by referring to the home memory 23 and transmits the location related information to the mobile station 10.
