Abstract

The present invention relates to a method and apparatus for efficiently controlling a minimization of drive test (MDT) in a plurality of public land mobile networks (PLMNs). The method for controlling an MDT of a terminal according to one embodiment of the present invention comprises the steps of: performing a tracking-area update; receiving a logged measurement configuration message; determining whether or not the received logged measurement configuration message comprises an MDT PLMN list; and a applying, if the MDT PLMN is comprised, the MDT PLMN list to the MDT. The method and apparatus according to the present invention may efficiently control an MDT in a plurality of PLMNs.

Claims

1. A Minimization of Driving Test (MDT) control method of a terminal, the method comprising:

performing Tracking Area Update;

receiving a Logged Measurement Configuration message;

determining whether the Logged Measurement Configuration message includes an MDT Public Land Mobile Network (PLMN) list; and

applying, when the MDT PLMN list is included, the MDT PLMN list to the MDT.

2. The method of claim 1, wherein the applying of the MDT PLMN list comprises:

determining whether a current Registered PLMN (RPLMN) matches one of a RPLMN at time when the Logged Measurement Configuration message is received or PLMNs included in the MDT PLMN list; and

performing, when the current RPLMN matches one of the RPLMN at time when the Logged Measurement Configuration message is received or PLMNs included in the MDT PLMN list, the MDT.

3. The method of claim 2, wherein the applying of the MDT PLMN list further comprises:

determining whether the Logged Measurement Configuration message includes an indication of Area Configuration; and

performing, when the Logged Measurement Configuration message includes the indication of Area Configuration and a current cell is indicated in the Area Configuration and included in at least one of a E-UTRAN Cell Global Identifier (ECGI) or a Tracking Area Code (TAC), the MDT.

4. The method of claim 1, wherein the MDT PLMN list comprises PLMNs selected from an equivalent PLMN (ePLMN).

18. The method of claim 3, wherein performing the MDT comprises determining whether the current cell is indicated in the Area Configuration and included in at least one of the ECGI or the TAC.

5. A Minimization of Driving Test (MDT) control method of a base station, the method comprising:

receiving an equivalent Public Land Mobile Network (ePLMN);

generating an MDT PLMN list with PLMNs selected from the ePLMN; and

transmitting a Logged Measurement Configuration message including the MDT PLMN list to a terminal.

6. The method of claim 5, wherein the generating of the MDT PLMN list comprises generating the MDT PLMN list in a form of a bitmap.

7. The method of claim 5, wherein the generating of the MDT PLMN list comprises generating the MDT PLMN list using PLMN Identifiers (IDs).

8. The method of claim 7, wherein the Logged Measurement Configuration message is transmitted through Analytic Signal (AS) signaling.

9. A Minimization of Drive Test (MDT) control apparatus of a terminal, the apparatus comprising:

a transceiver configured to transmit and receive data; and

a controller configured to control performing Tracking Area Update, receiving a Logged Measurement Configuration message, determining whether the Logged Measurement Configuration message includes an MDT Public Land Mobile Network (PLMN) list, and applying, when the MDT PLMN list is included, the MDT PLMN list to the MDT.

10. The apparatus of claim 9, wherein the controller is configured to control, when controlling applying the MDT PLMN list to the MDT:

determining whether a current Registered PLMN (RPLMN) matches one of a RPLMN at time when the Logged Measurement Configuration message is received or PLMNs included in the MDT PLMN list; and

performing, when the current RPLMN matches one of the RPLMN at time when the Logged Measurement Configuration message is received or PLMNs included in the MDT PLMN list, the MDT.

11. The apparatus of claim 10, wherein the controller is configured to control, when controlling applying the MDT PLMN list to the MDT:

determining whether the Logged Measurement Configuration message includes an indication of Area Configuration; and

performing, when the Logged Measurement Configuration message includes the indication of Area Configuration and a current cell is indicated in the Area Configuration and included in at least one of a E-UTRAN Cell Global Identifier (ECGI) or a Tracking Area Code (TAC), the MDT.

12. The apparatus of claim 9, wherein the MDT PLMN list comprises PLMNs selected from an equivalent PLMN (ePLMN).

13. A Minimization of Drive Test (MDT) control apparatus of a base station, the apparatus comprising:

a transceiver configured to transmit and receive data; and

a controller configured to control receiving an equivalent Public Land Mobile Network (ePLMN), generating an MDT PLMN list with PLMNs selected from the ePLMN, and transmitting a Logged Measurement Configuration message including the MDT PLMN list to a terminal.

14. The apparatus of claim 13, wherein the controller is configured to control, when controlling generating the MDT PLMN list, generating the MDT PLMN list in a form of a bitmap.

15. The apparatus of claim 14, wherein the controller is configured to control transmitting the Logged Measurement Configuration message through Analytic Signal (AS) signaling.

16. The apparatus of claim 13, wherein the controller is configured to control, when controlling generating the MDT PLMN list, generating the MDT PLMN list using PLMN Identifiers (IDs).

17. The apparatus of claim 16, wherein the controller is configured to control transmitting the Logged Measurement Configuration message through Analytic Signal (AS) signaling.
