Abstract
A base station () of a cellular communication system () comprises an RNC interface () which receives a radio link handover initiation message for a radio link from a radio network controller (). A switch delay processor () determines a handover switch delay and a characteristics processor () sets a characteristic of a radio link handover acknowledge message in response to the handover switch delay. A message generator () generates a radio link handover acknowledge message and transmits this to the radio network controller (). The radio network controller () comprises an RNC handover controller () which determines a radio link handover switch time in response to the characteristic. A better timing of the radio link handover may be achieved. The invention may e.g. be applicable to an HSDPA (High Speed Downlink Packet Access) service of a UMTS (Universal Mobile Telecommunication System) cellular communication system and may reduce the amount of data discarded from buffers during an HSDPA handover.
