Controlling dispatch of radio coverage drones

Abstract

A method for dispatching radio coverage drones to a geographical area of a failing node in a radio network, wherein the radio coverages drones are configured to re-establish operability of the failing node is disclosed. The method comprises steps being performed by a network node of generating () a radio coverage map, wherein the generated radio coverage map covers the geographical area of the failing node and geographical areas of adjacent nodes, identifies at least one mobile communication device having radio coverage from at least one of the adjacent nodes, and defines a size of the geographical area of the failing node, dynamically calibrating () the defined size of the geographical area of the failing node of the dynamically generated radio coverage map by: calculating () a first distance between the identified mobile communication device and a selected one of the adjacent nodes, wherein the identified mobile communication device has coverage from the selected adjacent node while being geographically closer to the failing node than to the selected adjacent node, deducing () a second distance between the failing node and the selected adjacent node, determining () the actual size of the geographical area of the failing node based on the second and the first distance, and determining () a number of radio coverage drones to be dispatched to the geographical area of the failing node, wherein the number of radio coverage drones is based on to the actual size of the geographical area of the failing node. Corresponding computer program product, arrangement, network node, and system are also disclosed.
