Abstract:
1. A user equipment for a Universal Mobile Telecommunications System (UMTS) system, the UMTS system defining a dedicated channel (DCH) active set and an enhanced-dedicated channel (E-DCH) active set, the user equipment comprising: a circuit configured to perform a first power measurement of a pilot signal from at least one first cell of a plurality of first cells, wherein the plurality of first cells are not included in the E-DCH active set and are included in the DCH active set; a circuit configured to perform a second-power measurement of a pilot signal from at least one second cell of a plurality of second cells, wherein the plurality of second cells are included in the E-DCH active set; a circuit configured to perform a third power measurement of a pilot signal from at least one third cell of a plurality of third cells, when the at least one third cell enters a reporting range, wherein the plurality of third cells are not included in the DCH active set; a circuit configured to determine when each of a plurality of events has been triggered, the plurality of events comprising: a circuit configured to send results of the first power measurement, the second power measurement, and the third power measurement to a radio network controller of the UMTS mobile communication system when the third event has been triggered; wherein the E-DCH active set is updated to replace said at least one second cell with the at least one first cell after the third event had been triggered and the results are transmitted to the said radio network controller.
