Abstract

Disclosed are a method and device for determining user equipment (UE) positioning information during a minimum drive test (MDT) process to ensure that during the MDT realization process, the acquisition of the UE position information is not limited by the positioning capabilities of a network positioning server or the UE, that is, a network side can determine the UE position information required by the MDT without the positioning support function of the positioning server and the UE. The method of the present invention for determining the user equipment (UE) positioning information during a minimum drive test (MDT) process comprises: selecting a UE in a connected state, and determining an MDT measurement result corresponding to the UE (S101); determining the UE positioning information, and adding the UE positioning information to the MDT measurement result corresponding to the UE (S102).

Claims

1. A method for determining location information of a User Equipment, UE, during a Minimum Drive Test, MDT, procedure, comprising:

selecting a UE in a connected state and determining an MDT measurement result corresponding to the UE; and

determining and adding the location information of the UE to the MDT measurement result corresponding to the UE,

wherein determining the location information of the UE comprises;

determining a Timing Advance, T_ADV, and an Angle of Arrival, AoA, corresponding to the UE, and

calculating the location information of the UE according to the T_ADV and the AoA corresponding to the UE;

or determining the T_ADV and the AoA corresponding to the UE and information of a serving cell where the UE is currently located as the location information of the UE.

2. The method according to claim 1, wherein determining the MDT measurement result corresponding to the UE comprises:

a network side equipment configuring the UE with an MDT measurement, triggering the UE to perform the MDT measurement and obtaining the MDT measurement result reported by the UE;

or

the network side equipment making the MDT measurement on the UE and determining the MDT measurement result corresponding to the UE.

3. The method according to claim 2, further comprising:

sending the MDT measurement result, to which the location information of the UE is added, to a Trace Control Entity.

4. The method according to claim 1, further comprising:

sending the MDT measurement result, to which the location information of the UE is added, to a Trace Control Entity.

5. The method according to claim 4, wherein sending the MDT measurement result, to which the location information of the UE is added, to the Trace Control Entity comprises:

recording multiple MDT measurement results and multiple pieces of the location information of the UE added to the MDT measurement results; and

sending the recorded multiple MDT measurement results and multiple pieces of the location information of the UE added to the MDT measurement results to the Trace Control Entity by reporting a trace record.

6. The method according to claim 4, wherein the MDT measurement result, to which the location information of the UE is added, is sent to the Trace Control Entity through an Element Management, EM.

7. An apparatus for determining location information of a User Equipment, UE, during a Minimum Drive Test, MDT, procedure, comprising:

an MDT measurement result determining component configured to select a UE in a connected state and determine an MDT measurement result corresponding to the UE; and

a location information adding component configured to determine and add the location information of the UE to the MDT measurement result corresponding to the UE,

wherein the location information adding component is configured to determine a Timing Advance, T_ADV, and an Angle of Arrival, AoA, corresponding to the UE; and

calculate the location information of the UE according to the T_ADV and the AoA corresponding to the UE, or determine the T_ADV and the AoA corresponding to the UE and information of a serving cell where the UE is currently located as the location information of the UE.

8. The apparatus according to claim 7, wherein the MDT measurement result determining component is configured to configure the UE with an MDT measurement, trigger the UE to perform the MDT measurement and obtain the MDT measurement result reported by the UE;

or is configured to make the MDT measurement on the UE and determine the MDT measurement result corresponding to the UE.

9. The apparatus according to claim 8, further comprising:

a location information sending component configured to send the MDT measurement result, to which the location information of the UE is added, to a Trace Control Entity.

10. The apparatus according to claim 7, further comprising:

a location information sending component configured to send the MDT measurement result, to which the location information of the UE is added, to a Trace Control Entity.

11. The apparatus according to claim 10, wherein the location information sending component is configured to record multiple MDT measurement results and multiple pieces of the location information of the UE added to the MDT measurement results;

and send the recorded multiple MDT measurement results and multiple pieces of the location information of the UE added to the MDT measurement results to the Trace Control Entity by reporting a trace record.

12. The apparatus according to claim 10, wherein the location information sending component is configured to send the MDT measurement result, to which the location information of the UE is added, to the Trace Control Entity through an Element Management, EM.
