Measurement based identification of floors in need for network related action

A network node for identifying floors in a building in need of a network related action based on radio signal parameter values, the network node comprising processing circuitry, the processing circuitry being configured to cause the network node to:

• obtain location data of a geographical location, the location data indicating a footprint of a building and height information of the building;
• obtain, for a set of user equipment, radio signal parameter values from measurements made at the geographical location, wherein the measurements are being indicative of geo-locations in terms of horizontal positions and vertical positions of the user equipment;
• identify, by comparing the horizontal positions of the user equipment with the location data, a first subset of the user equipment, wherein the first subset of the user equipment representing user equipment located within the footprint of the building, the first subset of the user equipment having radio signal parameter values that represent a first performance value that is verified to be below a first threshold value;
• associate, by comparing the vertical positions of the user equipment in the first subset of the user equipment with the location data, second subsets of the user equipment with the floors of the building, wherein each of the second subsets of the user equipment representing user equipment located at a respective one of the floors of the building, and the radio signal parameter values of each of the second subset of the user equipment represent representing a respective second performance value;
• and
• identify the floors in need of the network related action as any of the floors associated with one of the second subsets of the user equipment for which the second performance value is below a second threshold value.

A computer readable storage medium, having stored thereon a computer program comprising instructions which, when executed by a computer, cause the computer to perform a method for identifying floors in a building in need of a network related action based on radio signal parameter values, the method comprising:

• obtaining location data of a geographical location, the location data indicating a footprint of a building and height information of the building;
• obtaining, for a set of user equipment, radio signal parameter values from measurements made at the geographical location, the measurements being indicative of geo-locations in terms of horizontal positions and vertical positions of the user equipment;
• identifying, by comparing the horizontal positions of the user equipment with the location data, a first subset of the user equipment, the first subset of the user equipment representing user equipment located within the footprint of the building, the first subset of the user equipment having radio signal parameter values that represent a first performance value that is verified to be below a first threshold value;
• associating, by comparing the vertical positions of the user equipment in the first subset of the user equipment with the location data, second subsets of the user equipment with the floors of the building, each of the second subsets of the user equipment representing user equipment located at a respective one of the floors of the building, and the radio signal parameter values of each of the second subset of the user equipment representing a respective second performance value;
• and
• identifying the floors in need of the network related action as any of the floors associated with one of the second subsets of the user equipment for which the second performance value is below a second threshold value.
