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, the position information including 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 position information is deleted;
adding the position information to a request for setting up a communication channel between a wireless base station and the mobile station using a random access procedure;
transmitting the request from the mobile terminal to the wireless base 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.
