Abstract

A user terminal includes: a transmitter that transmits a measurement report including a measurement result of radio environments, to a base station; a receiver that receives request information requesting the user terminal to make detailed location information available using GNSS (Global Navigation Satellite System), from the base station; and a controller that attempts to make the detailed location information available so as to include the detailed location information in the measurement report, in a case where the receiver receives the request information.

Claims

1. A mobile communication system comprising:

a base station; and

a user terminal that transmits a measurement report including a measurement result of radio environments, to the base station, wherein

the base station transmits request information requesting the user terminal to make detailed location information available using GNSS (Global Navigation Satellite System), to the user terminal, and

the user terminal attempts to make the detailed location information available so as to include the detailed location information in the measurement report, in a case where the user terminal receives the request information from the base station.

2. The mobile communication system according to claim 1, wherein

the user terminal turns a GNSS receiver to an on state in response to a reception of the request information, in a case where the GNSS receiver is an off state when the user terminal receives the request information from the base station.

3. The mobile communication system according to claim 1, wherein

the user terminal transmits the measurement report not including the detailed location information when the user terminal does not have available detailed location information, even in a case where user terminal receives the request information from the base station.

4. The mobile communication system according to claim 1, wherein

the base station applies the request information to Immediate MDT, without applying the request information to Logged MDT.

5. The mobile communication system according to claim 1, wherein

the base station transmits the request information along with configuration information indicating that the user terminal should include location information in the measurement report, and

the user terminal receives the request information along with the configuration information.

6. The mobile communication system according to claim 5, wherein

the request information is an information element specified in a predetermined release number of a communication standard, and

the configuration information is an information element specified in not only the predetermined release number but also other release number older than the predetermined release number.

7. A base station comprising:

a receiver that receives a measurement report including a measurement result of radio environments, from a user terminal; and

a transmitter that transmits request information requesting the user terminal to attempt to make detailed location information available such that the measurement report includes the detailed location information using GNSS (Global Navigation Satellite System), to the user terminal.

8. A user terminal comprising:

a transmitter that transmits a measurement report including a measurement result of radio environments, to a base station;

a receiver that receives request information requesting the user terminal to make detailed location information available using GNSS (Global Navigation Satellite System), from the base station; and

a controller that attempts to make the detailed location information available so as to include the detailed location information in the measurement report, in a case where the receiver receives the request information.

9. A processor provided in a base station, executing:

a process for receiving a measurement report including a measurement result of radio environments, from a user terminal; and

a process for transmitting request information requesting the user terminal to attempt to make detailed location information available such that the measurement report includes the detailed location information using GNSS (Global Navigation Satellite System), to the user terminal.

10. A processor provided in a user terminal, executing:

a process for transmitting a measurement report including a measurement result of radio environments, to a base station;

a process for receiving request information requesting the user terminal to make detailed location information available using GNSS (Global Navigation Satellite System), from the base station; and

a process for attempting to make the detailed location information available so as to include the detailed location information in the measurement report, in a case where the receiver receives the request information.
