Method of collecting information in mobile communication system
First Claim
1. A method of collecting information used for adjustments with an information collecting server in a radio communication system, said method comprising, in said information collecting server:
- sending a trigger command simultaneously to mobile radio terminals currently located in a service area of the information collecting server, so that any of said mobile radio terminals capable of doing so and in response to said trigger command will be instructed to;
acquire a reception status of a radio signal for that mobile radio terminal;
acquire a coordinate position of said mobile radio terminal; and
send measured information including said reception status and said coordinate position to said information collecting server;
recording said measured information received from said mobile radio terminals sending said measured information; and
sending value information indicative of a value given for said measured information, which is provided to said mobile radio terminals when said measured information is received, such that the value indicated by said value information can be displayed in a mobile radio terminal when said value information is received.

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.

7. A method of collecting information used for adjustments with an information collecting server in a radio communication system connected to one or more mobile radio terminals for performing user communications, said method comprising, in said information collecting server:
-
sending a trigger command simultaneously to all of the one or more mobile radio terminals to instruct any said mobile radio terminal capable of so doing to; monitor a communication status of a communication connection using a common pilot channel, wherein said communication status corresponds to whether or not the mobile radio terminal has an existing communication connection using a common pilot channel, which satisfies predetermined criteria; detect as a trigger when a change of said communication status has satisfied a predetermined condition; and when one of said trigger commands is received and said trigger is detected for said change of communication status; acquire a reception status of a radio signal; acquire a coordinate position of said mobile radio terminal; and send measured information including said reception status and said coordinate position to said information collecting server; and sending value information indicative of a value given for said measured information, which is provided to said mobile radio terminals when said measured information is received such that the value indicated by said value information can be displayed in a mobile radio terminal when said value information is received. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A system for collecting information used for adjustments in a radio communication system for performing user communication, said system comprising:
-
one or more mobile radio terminals for, when a trigger command is received, acquiring a reception status of a radio signal and a coordinate position of the mobile radio terminal and sending measured information including said reception status and said coordinate position; and an information collecting server that sends said trigger command simultaneously to all of the one or more mobile radio terminals, and recording the measured information which has been received from said one or more mobile radio terminals, wherein, when said measured information is received, said information collecting server sends value information indicative of a value given for said measured information, which is provided to said mobile radio terminals, and wherein, when said value information is received in a mobile radio terminal, said mobile radio terminal displays the value indicated by said value information. - View Dependent Claims (15, 16, 17, 18)

19. A system for collecting information used for adjustments in a radio communication system for performing a user communication, said system comprising:
-
an information collecting server that sends a trigger command simultaneously to all of one or more mobile radio terminals currently located in a service area, and recording the measured information which is received from said mobile radio terminals, wherein, for each mobile radio terminal capable of recognizing said trigger command and of monitoring a communication status of a communication connection using a common pilot channel, said communication status corresponding to whether or not the mobile radio terminal has an existing communication connection using the common pilot channel which satisfies predetermined criteria and, if a trigger is detected when a change of said communication status has satisfied a predetermined condition of one of said predetermined criteria, or a trigger command is received, said mobile terminal will acquire a reception status of a radio signal and a coordinate position of the mobile radio terminal and will send measured information including said reception status and said coordinate position to said information collecting server, wherein, when said measured information is received, said information collecting server sends value information indicative of a value given for said measured 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. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A mobile radio terminal for sending information used for adjustments in a radio communication system for performing a user communication to an information collecting server, said mobile radio terminal comprising:
-
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 trigger command is received by said trigger information reception unit, that instructs 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 measured information including said reception status and said coordinate position to said information collecting server, wherein, when said measured information is received, said information collecting server sends value information indicative of a value given for said measured 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. - View Dependent Claims (30, 31, 32)
