 there are available resources. The RNC allocates them and sends an active set update message to the UE. The active set update message is followed by an active set complete message from the UE. The reporting range is the measured reference value based on Ec/10 from which the UE evaluates the triggering thresholds. The reporting range can be calculated from the best cell in the active set or from the sum of all cells that are included in the active set. Which option is used is set by the ActiveSetWeightingCoefficient parameter. The soft handover reporting events are as follows: 1A. When one of the neighbouring cells becomes better than the reporting range - an offset from the best cell in the active set defined by addition of a window parameter. Event 1A is sent when the triggering conditions stay true for the time-to-trigger period defined by the addition time parameter. Event 1A requests the RNC to add the cell that triggered the event to the active set. 1B. When one of the active set cells becomes lower than the reporting range - this offset is defined by the drop window parameter and is typically 2 dB lower than the window addition. Event 1B is sent when the triggering conditions stay true for the time-to-trigger period defined by the drop time parameter. Event 1B requests the RNC to remove the cell triggering event from the active set. 1C. When there are already a maximum number of allowed cells in the active set and one of the neigh- bouring cells becomes better than the worst cell in the active set. There is an offset given for the worst cell in the active set using a replacement window parameter. The neighbouring cell must stay better than the worst cell in the active set + the given offset for a time-to-trigger period, defined by the replacement time. If these conditions are true the UE sends a measurement report requesting a replacement of the worst cell in the active set with a new cell that triggered event 1C. 1D. This is an event indicating that the best cell of an active set has changed. The best cel
