Method and device for performing a logged measurement in a wireless communication system
A method for performing a logged measurement in wireless communication system is provided. The method includes receiving measurement configuration from a network, logging MDT (Minimization of Driving Tests) measurement, detecting whether a condition for state transition has occurred, performing state transition when the condition for state transition has occurred, and logging state transition information related to said state transition.
1. A method for performing a measurement by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, by the UE, a measurement configuration from a network;
performing, by the UE, a logging of measurement based on the measurement configuration;
reporting, by the UE, a result of measurement logging to the network,
wherein the result of measurement logging includes information related to a transition by the UE from a suspending logging to a resuming logging, and
wherein the information indicates a time spent related to the transition.
2. The method of claim 1 , wherein the information includes an indicator indicating that the transition has been made from the suspending logging to the resuming logging.
3. The method of claim 1 , wherein the information includes a condition for the suspending logging.
4. The method of claim 3 , wherein the condition for the suspending logging includes at least one of:
leaving, of the UE, from a RRC (radio resource control) state, which is configured to perform the logging of measurement;
leaving, of the UE, from a RAT (Radio Access Technology), which is configured to perform the logging of measurement;
leaving, of the UE, from a logging area;
leaving, of the UE, from a logging PLMN (Public Land Mobile Network); and
leaving, of the UE, from a state of normal camping.
5. The method of claim 1 , wherein the measurement configuration is a Minimization of Driving Tests (MDT) measurement configuration.
6. The method of claim 1 , wherein the information indicates a time duration from a moment of radio link failure to a moment of a completion for a radio link connection.
7. The method of claim 1 , wherein the information includes a condition for the resuming logging.
8. The method of claim 7 , wherein the condition for the resuming logging includes at least one of:
entering, of the UE, to a RRC (radio resource control), which is configured to perform the logging of measurement;
entering, of the UE, to a RAT (Radio Access Technology), which is configured to perform the logging of measurement;
entering, of the UE, to a logging area;
entering, of the UE, to a logging PLMN (Public Land Mobile Network); and
entering, of the UE, to a state of normal camping.
9. The method of claim 1 , wherein the logging of measurement is periodically performed by the UE.
10. An apparatus for performing a measurement in a wireless communication system, the apparatus comprising:
a Radio Frequency (RF) unit for receiving and transmitting a radio signal; and
a processor connected to the RF unit, the processor configured to:
receive a measurement configuration from a network;
perform a logging of measurement based on the measurement configuration; and
report a result of measurement logging to the network,
wherein the result of measurement logging includes information related to a transition from a suspending logging to a resuming logging, and
wherein the information indicates a time spent related to the transition.
11. The apparatus of claim 10 , wherein the information includes an indicator indicating that the transition has been made from the suspending logging to the resuming logging.
12. The apparatus of claim 10 , wherein the information includes a condition for the suspending logging.
13. The apparatus of claim 12 , wherein the condition for the suspending logging includes at least one of:
leaving, of the UE, from a RRC (radio resource control) state, which is configured to perform the logging of measurement;
leaving, of the UE, from a RAT (Radio Access Technology), which is configured to perform the logging of measurement;
leaving, of the UE, from a logging area;
leaving, of the UE, from a logging PLMN (Public Land Mobile Network); and
leaving, of the UE, from a state of normal camping.
14. The apparatus of claim 10 , wherein the measurement configuration is a Minimization of Driving Tests (MDT) measurement configuration.
15. The apparatus of claim 10 , wherein the information indicates a time duration from a moment of radio link failure to a moment of a completion for a radio link connection.
16. The apparatus of claim 10 , wherein the information includes a condition for the resuming logging.
17. The apparatus of claim 16 , wherein the condition for the resuming logging includes at least one of:
entering, of the UE, to a RRC (radio resource control), which is configured to perform the logging of measurement;
entering, of the UE, to a RAT (Radio Access Technology), which is configured to perform the logging of measurement;
entering, of the UE, to a logging area;
entering, of the UE, to a logging PLMN (Public Land Mobile Network); and
entering, of the UE, to a state of normal camping.
18. The apparatus of claim 10 , wherein the processor is further configured to periodically perform the logging of measurement.
