Abstract

According to one aspect of the present invention, a reporting method in a wireless communication system is provided. The method comprises: determining a service state; controlling positioning for acquiring position information based on the service state; acquiring information on the position of a terminal according to the positioning mode determined by said controlling; and reporting the acquired position information to a network.

First claim

What is claimed is:

1. A reporting method in a wireless communication system, the reporting method comprising:
receiving a measurement configuration, from a network, including information for performing a measurement, wherein the measurement configuration includes a plurality of thresholds;
determining a service state by measuring a quality of a serving cell;
controlling positioning for obtaining location information depending on the service state;
obtaining information on a location of a user equipment depending on a positioning mode determined by the control; and
reporting the obtained location information to the network,
wherein the positioning mode is deactivated when the quality of the serving cell is greater than a first threshold of the plurality of thresholds,
wherein the positioning mode includes a first positioning mode and a second positioning mode,
wherein the first positioning mode is activated when the quality of the serving cell is less than the first threshold but greater than a second threshold of the plurality of thresholds,
wherein the second positioning mode is activated when the quality of the serving cell is less than the second threshold, and
wherein the first threshold is greater than the second threshold.

2. The reporting method of claim 1 , wherein the obtaining the information on the location of the user equipment depending on the determined positioning mode is performed when the positioning mode is activated.

3. The reporting method of claim 2 , wherein the obtained location of the user equipment is logged alongside the measurement result and is reported to the network.

4. The reporting method of claim 1 , further comprising monitoring a downlink quality.

5. The reporting method of claim 4 , wherein the determining the service state includes sensing an occurrence of a radio link failure based on the monitoring.

6. The reporting method of claim 5 , wherein the controlling the positioning includes activating the positioning when the radio link failure is sensed.

7. The reporting method of claim 6 , wherein the determining the service state further includes determining that the user equipment recovers from the radio link failure when the user equipment performs RRC (Radio Resource Control) connection reestablishment.

8. The reporting method of claim 7 , wherein the controlling the positioning includes deactivating the positioning mode when determining recovery from the radio link failure.

9. The reporting method of claim 8 , further comprising sending, to the network, a radio link failure report reporting that the radio link failure is sensed,
wherein the radio link failure report includes the information on the location of the user equipment.

10. A wireless device operating in a wireless communication system, the wireless device comprising:
an RF (radio frequency) unit transmitting and receiving a radio signal; and
a processor operatively connected with the RF unit, the processor configured to:
receive a measurement configuration including information for performing a measurement, wherein the measurement configuration includes a plurality of thresholds;
determine a service state by measuring a quality of a serving cell;
control positioning for obtaining location information depending on the service state;
obtain information on a location of a user equipment depending on a positioning mode determined by the control; and
report the obtained location information to a network,
wherein the positioning mode is deactivated when the quality of the serving cell is greater than a first threshold of the plurality of thresholds,
wherein the positioning mode includes a first positioning mode and a second positioning mode,
wherein the first positioning mode is activated when the quality of the serving cell is less than the first threshold but greater than a second threshold of the plurality of thresholds,
wherein the second positioning mode is activated when the quality of the serving cell is less than the second threshold, and
wherein the first threshold is greater than the second threshold.

11. The wireless device of claim 10 , wherein the obtained location of the user equipment is logged alongside the measurement result and is reported to the network.
