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 proxy information reporting method performed by a wireless device in a wireless communication system, the method comprising:

when entering a proximity of a first target cell on a target frequency, reporting first proxy information indicating the entering the proximity to a serving cell; and

when leaving a proximity of any target cell on the target frequency after reporting the first proxy information, reporting second proxy information indicating the leaving the proximity to the serving cell,

wherein proxy information regarding the entering the proximity of any other target cell on the target frequency is not reported until the second proxy information indicating the leaving the proximity is sent after reporting the first proxy information.

2. The method of claim 1, wherein the reporting of the second proxy information to the serving cell comprises:

starting a suspension timer when leaving the proximity of the first target cell; and

reporting to the serving cell the second proxy information indicating the leaving the proximity when the suspension timer expires.

3. The method of claim 2, wherein the suspension timer stops when entering the proximity of the second target cell on the target frequency.

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

5. The method of claim 4, wherein regarding the stopped suspension timer, a suspension timer corresponding to the target frequency restarts when leaving the proximity of the first target cell.

6. The method of claim 1, wherein only when the target frequency is set to a measurement object after reporting the first proxy information, proxy information for entering the proximity of any other target cell on the target frequency is not reported until the second proxy information is sent.

7. The method of claim 1, further comprising receiving a proximity report configuration indicating the target frequency from the serving cell

8. The method of claim 1, further comprising receiving a proximity report configuration indicating the first target cell from the serving cell.

9. A wireless device for reporting proxy information, comprising:

a radio frequency (RF) unit for transmitting and receiving a radio signal; and

a processor operatively coupled to the RF unit, wherein the processor is configured for;

when entering a proximity of a first target cell on a target frequency, reporting first proxy information indicating the entering the proximity to a serving cell; and

when leaving a proximity of any target cell on the target frequency after reporting the first proxy information, reporting second proxy information indicating the leaving the proximity to the serving cell,

wherein proxy information regarding the entering the proximity of any other target cell on the target frequency is not reported until the second proxy information indicating the leaving the proximity is sent after reporting the first proxy information.

10. The wireless device of claim 9, wherein in order to report the second proxy information to the serving cell, the processor is configured for:

starting a suspension timer when leaving the proximity of the first target cell; and

reporting to the serving cell the second proxy information indicating the leaving the proximity when the suspension timer expires.

11. The wireless device of claim 10, wherein the suspension timer stops when entering the proximity of the second target cell on the target frequency.
