Method of correlating measurement result
Methods of MDT information logging and reporting are provided. In one embodiment, a method is provided to resolve shortcomings of prior art by correlating UL measurements with QoS information to enable UL performance analysis and accurate detection of coverage problems. In another embodiment, a method is provided to resolve the shortcomings of the prior art by making DL measurements and location information collecting or logging conditional on UL measurements.
1. A method comprising:
detecting an availability of an uplink (UL) measurement result by a user equipment (UE) in a wireless network;
triggering a location-related performance and a downlink-related performance upon the detection of the availability of the UL measurement result;
obtaining the uplink measurement result, a location-related measurement result and a downlink measurement result based on the location-related performance and the downlink-related performance; and
correlating the location-related measurement result, the downlink measurement result and the uplink measurement results for a performance test for the UE.
2. The method of claim 1 , wherein the location-related performance is a location-related measurement and the downlink-related performance is a downlink measurement are performed or recorded when the uplink measurement result becomes available.
3. The method of claim 1 , wherein the location-related performance is to log one or more location-related measurement result into a log and the downlink-related performance is to log one or more downlink measurement result into the log.
4. The method of claim 3 , further comprising:
transmitting the log to a network device.
5. A method comprising:
detecting an availability of a first uplink (UL) measurement result applicable to a user equipment (UE), by a network device in a wireless network;
performing a location-related performance and a downlink-related performance based on the availability of the first UL measurement result;
performing a second uplink measurement applicable to the UE and thereby generating a second uplink measurement result upon detecting the availability of the first UL measurement result;
obtaining a location-related measurement result, downlink measurement result, and the first uplink measurement result; and
correlating the location-related measurement result, the downlink measurement result, the first uplink measurement result, and the second uplink measurement result for a performance test for the UE.
6. The method of claim 5 , wherein the first UL measurement result is not detected and the location-related performance is to discards one or more location-related measurement result and the downlink-related performance is to discard one or more downlink measurement result non-relevant to uplink in a logging process.
7. The method of claim 5 , wherein the correlation is triggered when the first uplink measurement result becomes available.
8. The method of claim 7 , wherein the network receives the location-related measurement result from the UE when the first uplink measurement result becomes available.
9. The method of claim 5 , wherein the correlation is triggered when an UL/DL transmission is available or when it becomes known to the network that data is present in a transmission or re-transmission buffer.
10. The method of claim 9 , wherein the network receives the location-related measurement result from the UE when the UL/DL transmission is performed.
11. A user equipment (UE) comprising:
a radio frequency transceiver that transmits uplink signals and receives downlink signal;
a measurement module that detecting an availability of an uplink (UL) measurement result triggers a location-related performance and a downlink-related performance upon the detection of the availability of the UL measurement result, obtains location-related measurement result, downlink measurement result, and the uplink measurement result; and
a correlator that correlates the location-related measurement result, the downlink measurement result and the uplink measurement result for a performance test for the UE.
12. The UE of claim 11 , wherein the location-related performance is a location-related measurement and the downlink-related performance is a downlink measurement.
13. The UE of claim 11 , wherein the location-related performance is to log one or more location-related measurement result into a log, and the downlink-related performance is to log one or more downlink measurement result into the log.
14. The UE of claim 13 , further comprising:
a transmitter that transmits the log to a network device.
