SYSTEM FOR THE EFFICIENT RECOVERY OF DATA STORED IN THE INTERMEDIATE MEMORY OF NODES B AFTER THE CELL CHANGE OF A SHARED LINK DOWN HIGH-SPEED LINK IN SERVICE.

摘要

A user equipment, EU, which facilitates a high-speed downlink shared channel HS-DSCH change, the EU comprising: means for receiving (18) a wireless signal, the wireless signal carrying the resource control radio RRC, request the message associated with the HS-DSCH cell change; high speed access control means, MAC-hs media; rearrangement of buffers associated with MAC-hs media; the EU being characterized by comprising: means for releasing said rearrangement buffers after the receiving means have received the wireless signal, the MAC-hs media providing information indicative that the reordering buffers have been released are released. ; and means, in response to said information, to generate status reports (20), each of the status reports corresponding to a respective radio link control mode in acknowledgment mode, AM RLC, the corresponding requests with the HS-DSCH, indicating the status reports packet data units, PDUs, of the HS-DSCH, lost by the EU.
