Abstract

There are disclosed a method of and a system for collecting information related to operation of a radio communication system inexpensively and easily. A mobile radio terminal monitors a communication status of user communication, and detects as a trigger when the communication status has satisfied a predetermined condition. When a trigger is detected, the mobile radio terminal acquires a reception status of a radio signal and the position of the mobile radio terminal. The mobile radio terminal sends measured information including the reception status and the position to an information collecting server. The information collecting server receives the measured information from the mobile radio terminal and records therein the measured information which has been received.
