Method in a radio communication network

1. A method for monitoring network performance in a wireless communication network of sites comprising at least one site including multiple cells that communicate with wireless devices, each cell providing coverage in a geographical area and the wireless communication network having a cell coverage plan with a calculated performance, the method comprising:

a) retrieving geospatially located measurements from wireless devices;

b) connecting each geospatially located measurement to a cell;

c) arranging measurements into at least one cluster per cell;

d) identifying deviations from the cell coverage plan; and

e) initiating actions to reduce deviations,

wherein connecting each geospatially located measurement comprises virtually connecting measurement points indicating no coverage to the cell.

2. The method according to claim 1 , wherein connecting each geospatially located measurement further comprises removing measurements not possible to connect to a cell.

3. The method according to claim 1 , wherein the method further comprises identifying measurement points indicating no coverage belonging to at least one of the categories:

Out of service;

emergency calls only; and

low signal strength.

4. The method according to claim 1 , wherein the step of arranging measurements into at least one cluster further comprises clustering measurement points indicating no coverage and connecting them virtually to the closest cell.

5. The method according to claim 4 , wherein the action comprises repairing hardware faults.

6. The method according to claim 1 , further comprising removing outliers per cell before arranging measurements into the at least one cluster per cell.

7. The method according to claim 6 , wherein the step of removing outliers is performed using a machine learning technique.

8. The method according to claim 1 , wherein identifying deviations further comprises determining actual performance in the wireless communication network and comparing the actual performance with the calculated performance.

9. The method according to claim 1 , wherein the method further comprises continuously updating the measurements by repeating steps a)-e).

10. The method according to claim 9 , wherein the steps a)-e) are repeated at regular intervals and/or on demand.

11. The method according to claim 1 , wherein the step of arranging measurements into at least one cluster per cell is based on a distance function.

12. The method according to claim 11 , wherein the distance function is determined using machine learning techniques applying latitude/longitude/altitude information.

13. The method according to claim 1 , wherein each cluster having a cluster centre and the step of arranging measurements into at least one cluster per cell further comprises tracking the position of each cluster centre over time.

14. A non-transitory computer program product for monitoring network performance in a wireless communication network, wherein the non-transitory computer program product comprises instructions which, when executed on at least one processor, cause the at least one processor to carry out the method according to claim 1 .

15. A non-transitory computer-readable storage medium including a computer program to monitor network performance in a wireless communication network according to the method of claim 1 .

16. A system for monitoring network performance in a wireless communication network comprising multiple cells that communicate with wireless devices, each cell providing coverage in a geographical area and the wireless communication network having a cell coverage plan with a calculated performance, wherein the system comprises a receiver configured to retrieve geospatially located measurements from wireless devices, a processing unit configured to perform the method according to claim 1 .

17. The system according to claim 16 , further comprising a memory configured to carry the computer program to perform the steps of

a) retrieving geospatially located measurements from wireless devices;

b) connecting each geospatially located measurement to a cell;

c) arranging measurements into at least one cluster per cell;

d) identifying deviations from the cell coverage plan; and

e) initiating actions to reduce deviations.

18. The system according to claim 16 , wherein the system further comprises a presenting unit configured to indicate differences between identify deviations and the cell coverage plan.
