Abstract

Provided is a method for reporting carried out by a terminal in a wireless communication system. The method comprises: receiving a public land mobile network (PLMN) list, which is information on one or more of PLMNs on which a logged minimization drive test (MDT) is valid; receiving information for executing the logged MDT; logging a measurement on the basis of the information for executing the logged MDT; entering a target cell in a radio resource control (RRC) connected state; determining whether or not the logged measurement is reportable; and if determined possible to report to the target cell, reporting the whole or a part of the logged measurement to the target cell. Whether or not the logged measurement can be reported is determined on the basis of the PLMN list.

Claims

1. A method for reporting performed by user equipment (UE) in a wireless communication system, comprising:

receiving a Public Land Mobile Network (PLMN) list that is information about at least one PLMN whose logged Minimization Drive Test (MDT) is valid;

receiving information for executing the logged MDT;

logging measurement based on the information for executing the logged MDT;

entering a Radio Resource Control (RRC)_connected state for a target cell;

determining whether reporting the logged measurement is possible or not; and

reporting part of or full logged measurement to the target cell if reporting the logged measurement to the target cell is possible,

wherein determining whether reporting the logged measurement is possible or not is based on the PLMN list.

2. The method of claim 1, wherein the PLMN list comprises at least one identity of the at least one PLMN.

3. The method of claim 2, wherein determining whether reporting the logged measurement is possible or not comprises,

determining that reporting the logged measurement to the target cell is possible, if an identity of a PLMN for the target cell is included in the at least one identity of the at least one PLMN in the PLMN list and the logged measurement to be reported to the target cell is present.

4. The method of claim 3, wherein the PLMN list and the information for performing the logged MDT are transmitted in a logged measurement configuration that is an RRC message.

5. The method of claim 1, wherein reporting the part of or the full logged measurement to the target cell comprises:

sending a logged measurement-available indicator to the target cell, the logged measurement-available indicator indicating that the logged measurement to be reported to the target cell is present;

receiving a measurement report request from the target cell as a response to the logged measurement-available indicator; and

sending the part of or the full logged measurement to the target cell in response to the measurement report request.

6. The method of claim 1, wherein the information for the logged MDT measurement comprises:

logging duration indicating duration for which the logged MDT is performed; and

a logging interval indicating an interval in which the logging is performed.

7. The method of claim 6, wherein logging the measurement comprises:

logging measurement every interval within the logging duration from a point of time at which the information for the logged MDT measurement is received; and

suspending the logging when the duration elapses.

8. A wireless apparatus comprising:

a transceiver transmitting and receiving radio signals; and

a processor is operably coupled to the transceiver, the processor is configured to;

receive information for executing the logged Minimization Driving Test (MDT);

log measurement based on the information for executing the logged MDT;

enter a Radio Resource Control (RRC)_connected state for a target cell;

determine whether reporting the logged measurement is possible or not; and

report part of or full logged measurement to the target cell if reporting the logged measurement to the target cell is possible,

wherein determining whether reporting the logged measurement is possible or not is based on the PLMN list.

9. The wireless apparatus of claim 8, wherein the PLMN list comprises at least one identity of the at least one PLMN.

10. The wireless apparatus of claim 9, wherein determining whether reporting the logged measurement is possible or not comprises

determining that reporting the logged measurement to the target cell is possible, if an identity of a PLMN for the target cell is included in the at least one identity of the at least one PLMN in the PLMN list and the logged measurement to be reported to the target cell is present.

11. The wireless apparatus of claim 10, wherein the PLMN list and the information for performing the logged MDT are transmitted in a logged measurement configuration that is an RRC message.

12. A method for reporting performed by a user equipment (UE) in a wireless communication system, comprising:

receiving a Public Land Mobile Network (PLMN) list that is information about a PLMN whose radio link failure report is valid;

detecting a radio link failure;

generating radio link failure information that is information about the radio link failure;

entering a Radio Resource Control (RRC)_connected state for a target cell;

determining whether reporting the radio link failure information to the target cell is possible or not; and

reporting the radio link failure information to the target cell if reporting the radio link failure information to the target cell is possible,

wherein determining whether reporting the radio link failure information to the target cell is possible or not is based on the PLMN list.

13. The report method of claim 12, wherein the PLMN list comprises at least one identity of the at least one PLMN.

14. The report method of claim 13, wherein determining whether reporting the radio link failure information is possible or not comprises

determining that reporting the radio link failure information to the target cell is possible if an identity of a PLMN for the target cell is included in the at least one identity of the at least one PLMN in the PLMN list and the radio link failure information to be reported to the target cell is present.
