RADIO NETWORK NODE, AND METHOD FOR DETERMINING WHETHER A WIRELESS DEVICE IS A SUITABLE CANDIDATE FOR HANDOVER TO A TARGET CELL FOR LOAD BALANCING REASONS

摘要

A method in a radio network node for determining whether a wireless device is a suitable candidate for handover to a target cell for load balancing reasons. The radio network node serves a source cell. The method comprises determining (201) a first level of coverage of the target cell based on a first measurement report. The method further comprises storing (202) measurement data obtained from a second measurement, being at least one of a layer 2 and a layer 1 measurement. The method further comprises establishing (203) a correlation between the determined first level of coverage and the stored measurement data and updating (204) statistical data based on the established correlation. The method further comprises determining (205) whether the wireless device is a suitable candidate for handover to the target cell for load balancing reasons, based on the updated statistical data.
