Abstract

Provided is a method for reporting by a terminal in a wireless communication system. The method comprises: receiving positioning-limiting information from a network; and determining whether to allow positioning on the basis of the positioning limiting information. The method additionally comprises, if the positioning is allowed, acquiring location information by means of positioning, and reporting the location information via a network.

First claim

What is claimed is:

1. A report method by a user equipment in a wireless communication system, the method comprising:
receiving a logged measurement configuration including configuration information for a logged Minimization Driving Test (MDT) and positioning restriction information from a network; and
determining whether positioning is permitted based on the positioning restriction information,
entering a Radio Resource Control (RRC) idle state when the positioning is permitted;
obtaining location information by performing the positioning in the RRC idle state;
performing a measurement on a serving cell or at least one neighbor cell based on the logged measurement configuration; and
reporting the location information to the network.

2. The report method of claim 1 , wherein the positioning restriction information is indicates a start time point and an end time point of a time interval in which the positioning of the user equipment is permitted.

3. The report method of claim 2 , wherein determining whether the positioning is permitted comprises determining whether the user equipment is operating between the start time point and the end time point.

4. The report method of claim 1 , wherein:
the positioning restriction information indicates a length of a time interval during which the positioning is permitted, and
the method further comprises starting a restriction timer based on the positioning restriction information.

5. The report method of claim 4 , wherein determining whether the positioning is permitted comprises determining whether the restriction timer is expired.

6. The report method of claim 1 , wherein the positioning restriction information is indicative of coverage in which the positioning is permitted.

7. The report method of claim 6 , wherein:
the coverage in which the positioning is permitted is at least one cell, and
the positioning restriction information comprises a cell list indicative of the at least one cell.

8. The report method of claim 7 , wherein determining whether the positioning is permitted comprises determining whether a serving cell of the user equipment is indicated by the cell list.

9. The report method of claim 6 , wherein:
the coverage in which the positioning is permitted is at least one frequency, and
the positioning restriction information comprises a frequency list indicative of the at least one frequency.

10. The report method of claim 9 , wherein determining whether the positioning is permitted comprises determining whether an operation frequency of the serving cell of the user equipment is indicated by the frequency list.

11. The report method of claim 1 , further comprising:
logging the results of the measurement and the location information if the positioning is permitted,
wherein reporting the location information to the network comprises reporting a report message, comprising the logged measured results and location information, to the network.

12. The report method of claim 11 , further comprising:
logging the results of the measurement if the positioning is not permitted; and
reporting the report message, comprising the logged measured results, to the network.

13. A wireless apparatus operating in a wireless communication system, the wireless apparatus comprises:
a Radio Frequency (RF) unit that sends and receives radio signals; and
a processor that is functionally coupled to the RF unit and operates,
wherein the processor is configured to:
receive a logged measurement configuration including configuration information for a logged Minimization Driving Test (MDT) and positioning restriction information from a network;
determine whether positioning is permitted based on the positioning restriction information,
enter a Radio Resource Control (RRC) idle state when the positioning is permitted;
obtain location information by performing the positioning in the RRC idle state,
perform a measurement on a serving cell or at least one neighbor cell based on the logged measurement configuration, and
report the location information to the network.
