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.

Claims

1. A mobile radio terminal for sending information used for adjustments in a radio communication system for performing user communications to an information collecting server collecting data for maintenance and adjustment activities for a service area coverage of said radio communication system, said mobile radio terminal comprising:

a communication status acquisition unit that acquires a communication status of a communication connection using a traffic channel, wherein said communication status corresponds to whether or not the mobile radio terminal has an existing communication connection using the traffic channel which satisfies predetermined criteria;

a trigger information reception unit that receives a trigger command from said information collecting server;

a reception status acquisition unit that acquires a reception status of a radio signal;

a positional information acquisition unit that acquires a coordinate position of the mobile radio terminal; and

a control unit, triggerable when said communication status acquired by said communication status acquisition unit has satisfied one of a predetermined condition of one of said predetermined criteria or said trigger command is received by said trigger information reception unit, instructing said reception status acquisition unit to acquire said reception status and instructing said positional information acquisition unit to acquire said coordinate position, and, when said reception status and said coordinate position are acquired, sending information including said reception status and said coordinate position to said information collecting server.

2. A mobile radio terminal according to claim 1, wherein said predetermined condition comprises an occurrence of a forced disconnection of the user communication.

3. A mobile radio terminal according to claim 1, wherein said predetermined condition comprises an occurrence of a handover failure.

4. A mobile radio terminal according to claim 1, wherein said predetermined condition comprises a lowering of a throughput of said user communication below a predetermined threshold value.

5. A mobile radio terminal according to claim 1, wherein said predetermined condition comprises a call which is made.

6. A mobile radio terminal according to claim 1, wherein when said information is received, said information collecting server sends value information indicative of a value given for said information, which is provided to said mobile radio terminal, and wherein, when said value information is received, said mobile radio terminal displays the value indicated by said value information.

7. A mobile radio terminal according to claim 1, wherein said radio communication system comprises a CDMA radio communication system.

8. The mobile radio terminal according to claim 1, wherein said acquiring a reception status further includes acquiring at least one of a received signal quality and a received signal intensity of a common channel.

9. The mobile radio terminal according to claim 1, wherein said acquiring said coordinate position information further includes acquiring coordinate information of said mobile radio terminal by using GPS (Global Positioning System).
