Abstract

Provided are a method and a wireless device for reporting proxy information in a wireless communication system. As the wireless device enters the proximity of a first target cell on a target frequency, the wireless device reports first proxy information indicating entering the proximity to a serving cell. Before the wireless device transmits proxy information indicating leaving the proximity after reporting the first proxy information, the wireless device does not report proxy information on entering the proximity of any other target cell on the target frequency.

Claims

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

receiving proximity indication configuration information which includes suspending timer information for a suspension timer;

when entering, by the UE, a proximity of a first target cell on a target frequency, reporting, from the UE to a serving cell, first proxy information indicating that the UE has entered the proximity of the first target cell;

starting the suspension timer when the UE leaves the proximity of the first target cell,

wherein if the suspension timer is running, the UE does not transmit any proxy information indicating that the UE has entered a proximity of any target cell on the target frequency when the UE enters the proximity of the any target cell; and

when the suspension timer expires, reporting, to the serving cell, second proxy information indicating that the UE has left the proximity of the any target cell after the UE leaves the proximity of the any target cell.

2. The method of claim 1, wherein if the suspension timer is running, the UE does not transmit any proxy information indicating that the UE leaves the proximity of the any target cell when the UE leaves the proximity of the any target cell.

3. The method of claim 1, wherein the suspension timer stops when the UE enters the proximity of a second target cell on the target frequency.

4. The method of claim 3, wherein the suspension timer is set for the target frequency.

5. The method of claim 4, wherein the stopped suspension timer restarts when the UE leaves the proximity of the second target cell.

6. The method of claim 3, wherein when the target frequency is set to a measurement object, the UE does not transmit the proximity information indicating that the UE enters the proximity of the second target cell while the suspension timer is running.

7. The method of claim 1, wherein the method further comprises receiving, from the serving cell, a proximity report configuration which indicates the second target cell to which the suspension timer is applied.

8. A user equipment (UE), the UE comprising:

a radio frequency (RF) unit that transmits and receives a radio signal; and

a processor operatively coupled to the RF unit, that;

controls the RF unit to receive proximity indication configuration information which includes suspending timer information for a suspension timer;

reports, to a serving cell, first proxy information indicating that the UE has entered a proximity of a first target cell on a target frequency, when the UE enters the proximity of the first target cell;

starts a suspension timer when the UE leaves the proximity of the first target cell,

wherein if the suspension timer is running, the UE does not transmit any proxy information indicating that the UE enters a proximity of any target cell on the target frequency when the UE enters the proximity of the any target cell, and

when the suspension timer expires, reports, to the serving cell, second proxy information indicating that the UE has left the proximity of the any target cell after the UE leaves the proximity of the any target cell.

9. The UE of claim 8, wherein if the suspension timer is running, the UE does not transmit any proxy information indicating that the UE leaves the proximity of the any target cell when the UE leaves the proximity of the any target cell.

10. The UE of claim 8, wherein the suspension timer stops when the UE enters the proximity of a second target cell on the target frequency.

11. The UE of claim 10, wherein the suspension timer is set for the target frequency.

12. The UE of claim 11, wherein the stopped suspension timer restarts when the UE leaves the proximity of the second target cell.

13. The UE of claim 10, wherein when the target frequency is set to a measurement object, the UE does not transmit the proximity information indicating that the UE enters the proximity of the second target cell while the suspension timer is running.

14. The UE of claim 8, wherein the processor further controls the RF unit to receive, from the serving cell, a proximity report configuration which indicates the second target cell to which the suspension timer is applied.
