CONTROLLER FOR FACILITATING CHANGE OF SERVING HIGH SPEED FORWARD PACKET ACCESS CELL, PARTICULARLY CONCERNED WITH REDUCING AND POTENTIALLY AVOIDING DATA RESTORATION BY HANDOVER

摘要

PURPOSE: A controller for facilitating a change of a serving high speed forward packet access cell is provided to reduce the amount of data stalled in a source node after changing of a serving HS(High Speed)-DSCH(Downlink Shared CHannel) cell. CONSTITUTION: Data from a data source(189) is received by a controller. A cell handover control circuit(191) provides control data to a cell interface circuit(199). Data from a data handling circuit(192) is provided to a cell interface circuit(199). The cell handover control circuit(191) facilitates communication with a UE by providing a HS-DSCH cell change command. The data handling circuit(192) transmits data and executes a flow control. A rate control circuit(203) receives data from the cell handover controller in response to a decision on a cell change by a cell changing circuit(194) or generation of a cell change request re-configuration message received from a cell change requesting circuit(195).
