Abstract

A mobile communications terminal includes positional information generator configured to generate positional information indicating a current position of the terminal, receiver which receives identification information sent from the base station of the second mobile communication network, notification information generator configured to generate notification information including the identification information and the positional information generated at the time of receiving the identification information, and transmitter which transmits the notification information to the service area calculation apparatus via the first mobile communication network to derive the information concerning the service area.

Claims

1. A mobile communication terminal adapted to communicate with a service area calculation apparatus via a first mobile communication network comprising:

a positional information generator configured to generate positional information indicating a current position of the mobile communication terminal;

a receiver which receives identification information sent from a base station of a second mobile communication network, the second mobile communication network being provided by a different provider from the first mobile communication network;

a time information generator configured to generate time information indicating a current time;

a notification information generator configured to generate notification information including the identification information and the positional information generated at the time of receiving the identification information and the time information; and

a transmitter which transmits the notification information to the service area calculation apparatus via the first mobile communication network.

2. The mobile communications terminal according to claim 1, wherein the position information generator generates the positional information based on a GPS (global positioning system) signal.

3. The mobile communications terminal according to claim 1, wherein the receiver receives a MAC (media access control) address as the identification information.

4. The mobile communications terminal according to claim 1, wherein the position information generator generates the positional information based on a reception state of each of signals transmitted from a plurality of different base stations.

5. The mobile communications terminal according to claim 1, wherein the position information generator generates the positional information based on a declination of signals received by a plurality of different antennas.

6. The mobile communications terminal according to claim 1, wherein the position information generator generates the positional information based on a position of the base station.

7. The mobile communications terminal according to claim 1, wherein the receiver receives an IP (internet protocol) address as the identification information.

8. The mobile communications terminal according to claim 1, wherein the receiver receives the identification information, when the second mobile communication network is a network with which the mobile communications terminal has not made a contract.
