Abstract
The invention is directed towards determining whether a hard handover should be performed of a mobile station () in relation to a first group of cells () including a number of active cells () and handled by a first cell handling device () to a second group of cells () handled by a second cell handling device (), when the cell handling devices lack a direct communication link (lur). Either the first cell handling device or the mobile station obtains measurements of link quality between the mobile station and cells of the groups, determines a first and second total quality factor for the groups, performs an evaluation of a preferred group involving comparing the first total quality factor with the second quality factor and initiates a handover from the first group to the second group if the second group is preferred.
