Abstract  Abstract

PROBLEM TO BE SOLVED: To shorten a waiting time during a changing procedure of an HS-DSCH cell on a service side and potentially prevent the missing of transmission of packet data units.

SOLUTION: In order to efficiently recover data buffered by a source node B a new reference is introduced for UE that generates a status report about a PDU as soon as possible following notification about the changing of a cell which is indicated by an RRC procedure. A PDU status may be indicated about each wireless link controller related to an HS-DSCH transfer channel. Further SRNC can wait for the PDU status report before the new transmission of data is started in a target cell depending on the change of the HS-DSCH cell on an internode B service side.
