Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and apparatus for controlling optimization of handover procedures between universal terrestrial radio access (UTRA) Release 6 (R6) cells and UTRA Release 7 (R7) cells.

SOLUTION: When a wireless transmit/receive unit (WTRU) is moving between an R6 cell and an R7 cell or between R7 cells a handover is initiated from a source Node-B to a target Node-B. In the R7 cell enhanced medium access control (MAC) functionality including flexible radio link control (RLC) protocol data unit (PDU) size and high speed MAC (MAC-hs) segmentation and multiplexing of different priority queues in the WTRU are supported. Changes that occur in the WTRU are caused by that the WTRU moves between the R6 cell and the R7 cell. When the WTRU moves between these cells a network has to reconfigure the WTRU using a new structure. After the handover a MAC layer and/or an RLC layer are reconfigured or reset based on functionality supported by the target Node-B.
