Abstract
A method of a controller node arranged to act with or within a cellular radio access network, RAN, is disclosed. The method comprises determining mobility data for UEs in active mode in at least a part of the RAN, estimating mobility data for UEs in idle mode in the at least the part of the RAN and determining reliability of the mobility data estimates, causing the RAN to page, when reliability of mobility data estimates of a set of the idle UEs is below a threshold, the set of the idle UEs and receive updated position information for the mobility data estimates, and determining a mobility situation within the at least the part of the RAN from the determined mobility data for the active UEs and the estimated mobility data for the idle UEs. The method further comprises comparing the determined mobility situation with one or more stored mobility situation data, and taking one or more control actions for the RAN when a change or anomaly is discovered in the determined mobility situation and based on the comparison. Such a controller node and a computer program therefor are also disclosed.
