Abstract

A method including collecting position information indicating a position of an area to which a wireless communication service is not provided, transmitting the position information from the mobile terminal to a wireless base station using a random access procedure for setting up a communication channel between the wireless base station and the mobile station, and identifying the area which is within a cell range of the wireless base station and to which the wireless communication service is not provided.

Claims

1. A method comprising:

collecting position information indicating a position of an area to which a wireless communication service is not provided, the collecting being performed by a mobile terminal;

transmitting the position information from the mobile terminal to a wireless base station using a random access procedure for setting up a communication channel between the wireless base station and the mobile station; and

identifying the area which is within a cell range of the wireless base station and to which the wireless communication service is not provided, the identifying being performed by the wireless base station.

2. The method according to claim 1, wherein

the position information includes transformed information which is obtained by transforming geographic position information in accordance with a predetermined transformation and whose information amount is smaller than an information amount of the geographic position information, and the geographic position information is information directly indicating the position of the area with latitude and longitude.

3. The method according to claim 2, further comprising

reporting the predetermined transformation from the wireless base station to the mobile terminal, wherein

the collecting collects the position information by transforming the geographic position information into the transformed information with the transportation reported by the reporting.

4. The method according to claim 1, wherein

the position information includes transformed information whose information amount is smaller than an information amount of geographic position information directly indicating the position of the area with latitude and longitude and which is obtained by transforming, in accordance with a predetermined transformation, bit data that remains after a portion of bit data of the geographic information is deleted.

5. The method according to claim 4, further comprising

reporting deletion information identifying the predetermined transformation and the deleted portion of bit data from the wireless base station to the mobile terminal, wherein

the collecting deletes the portion of bit data by using the deletion information reported by the reporting, and collects the position information by transforming, into the transformed information, bit data included in the geographic position information by using the transformation reported by the reporting.

6. The method according to claim 1, further comprising

designating a wireless resource that is used by the mobile terminal to transmit the position information using the random access procedure, the designating being performed by the wireless base station with respect to the mobile terminal, wherein

the transmitting transmits the position information using the wireless resource designated by the designating.

7. A wireless base station comprising:

reception unit to receive position information using a random access procedure for setting up a communication channel between the wireless base station and a mobile terminal, the position information being transmitted from the mobile terminal and identifying a position of an area which is within a cell range of the wireless base station and to which a wireless communication service is not provided; and

identification unit to identify the position of the area in accordance with the position information received by the reception unit.

8. A mobile terminal comprising:

collection unit to collect position information identifying a position of an area which is within a cell range of a wireless base station and to which a wireless communication service is not provided; and

transmission unit to transmit the position information to the wireless base station using a random access procedure for setting up a communication channel between the wireless base station and the mobile station.

9. A wireless communication system comprising:

a mobile terminal; and

a wireless base station;

wherein

the mobile terminal

collects position information identifying a position of an area which is within a cell range of the wireless base station and to which a wireless communication service is not provided, and

transmits the position information to the wireless base station using a random access procedure for setting up a communication channel between the wireless base station and the mobile station, and

the wireless base station

receives the position information transmitted from the mobile terminal by using the random access procedure, and

identifies the position of the area in accordance with the position information received by the reception means.
