The invention is directed towards determining whether a hard handover should be performed of a mobile station (48) in relation to a first group of cells (16, 18, 20, 24) including a number of active cells (16, 18, 20) and handled by a first cell handling device (10) to a second group of cells (32, 36, 38) handled by a second cell handling device (26), 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.
A method of determining whether a hard handover should be performed of a mobile station in relation to a first group of cells comprising more than one cell and handled by a first cell handling device to a second group of cells comprising at least one cell and handled by a second cell handling device, where there is no direct communication link between the first and second cell handling devices and the first group includes a number of active cells that the mobile station is communicating with, comprising the steps of:
A communication device for determining whether a hard handover should be performed of a mobile station in relation to a first group of cells comprising more than one cell and handled by a first cell handling device to a second group of cells comprising at least one cell and handled by a second cell handling device, where there is no direct communication link between the first and second cell handling devices and the first group includes a number of active cells that the mobile station is communicating with, comprising:
A telecommunication network comprising:
A computer program product for determining whether a hard handover should be performed of a mobile station in relation to a first group of cells comprising more than one cell and handled by a first cell handling device to a second group of cells comprising at least one cell and handled by a second ceil handling device, where there is no direct communication link between the first and second cell handling devices and the first group includes a number of active cells that the mobile station is communicating with, comprising computer program code to make a communication device perform, when said code is loaded into the communication device:
