Abstract
A control node (26) of a radio access network participating in a cell change procedure is permitted to begin sending HS-DSCH data frames to a target radio base station (28) even before the control node knows a calculated capacity allocation for the target cell. Such pre-knowledge transmission of HS-DSCH data frames by the control node effectively reduces a control node (e.g., RNC) bitrate transmission gap which otherwise would occur had the control node waited to send the high-speed downlink shared channel (HS-DSCH) data frames after the control node had been informed of the calculated capacity allocation. The control node is permitted to begin sending the HS-DSCH data frames even prior to an activation time (AT), and typically just after a switch time (ST).
