PROBLEM TO BE SOLVED: To supply a computer program and a database which are saved by a home server in response to a request from a portable terminal. SOLUTION: A user terminal 1 uses a built-in PHS and accesses a radio base station 2 or a home server 5. The station 2 transmits a user ID to a directory server 4 through a network 3 in response to a request from the terminal 1 and also transmits and receives information to/from the server 5. The server 4 registers and manages an access method to the server 5 corresponding to the user ID, and when a user ID is inputted from the station 2, the server 4 retrieves a corresponding home server 5 and transfers information. The server 5 unitarily manages information utilized by users and supplies designated information in response to a request from the station 2. |
