Abstract:
1. A method of handing over a user terminal from a source cell to a target cell of a wireless network, comprising: for at least one candidate cell, obtaining a measure of signal strength between the user terminal and the at least one candidate cell; for the at least one candidate cell, selecting at least one of a first value, a second value and a reference value, the first value being associated with a load of the source cell and the second value being associated with a load differential between the load of the source cell and the load of the at least one candidate cell; for the at least one candidate cell, setting a threshold by computing a maximum of the reference value and a minimum of the first value and the second value; for the at least one candidate cell, comparing the measure of signal strength to the threshold; designating, as the target cell, the at least one candidate cell if the measure of signal strength associated with the at least one candidate cell is greater than the threshold; and requesting a handover to the designated target cell.
