IPC: G06F21/33
Filed: 2001-07-10
Abstract: PROBLEM TO BE SOLVED: To exactly obtain information which can be obtained only on the spot. SOLUTION: When a portable terminal 1 that a user U carries moves to an area B, position information from the portable terminal 1 is received by a base station 3b in the area B and it is sent to a managing center 2. The managing center 2 judges that the portable terminal 1 moves to the area since a position signal is supplied from the base station 3b and gives the portable terminal 1 an instruction to transmit an electronic stamp B to the base station 3b. Thus, the portable terminal 1 can obtain the electronic stamp B showing that it is in the area B. When the portable terminal 1 similarly moves to the areas A and C, it can obtain the electronic stamps A and C in the areas. Inter- area information which can be obtained only in the areas A, B and C is stored in the information distribution server 4. The electronic stamps A, B and C are sent to the information distribution server 4 from the portable terminal 1. Consequently, inter-area information on the areas A, B and C are distributed.
