The present invention relates to an arrangement, a communication network node and a method of saving radio resources during handover in a communication network system comprising a plurality of communication network nodes (15a, 15b, 15c) communicating with one or more user equipments (18). Each network node (15a, 15b, 15c) is serving at least one cell (19) through and in which the user equipments (18) are moving. The method and arrangement is based on: collection of long term handover statistics (1); selective triggering of Multiple Cell Preparation (2); definition of a Secondary Target Cell List (3); exclusion from the Secondary Target Cell List of cells rarely used (4); preparation of the cells on the Secondary Target Cell List for handover (5). |
