METHOD AND APPARATUS FOR CONTROLLING HANDOVER BETWEEN UTRA R6 CELLS AND R7 CELLS Russian patent published in 2012 - IPC H04W36/02 

Abstract RU 2448437 C2

FIELD: information technology.

SUBSTANCE: method and apparatus for controlling an optimisation of handover procedures between universal terrestrial radio access (UTRA) release 6 (R6) cells and UTRA release 7 (R7) cells are disclosed. When a wireless transmit/receive unit (WTRU) is moving between an R6 cell and an R7 cell, or between R7 cells, handover is initiated from a source Node B to a target Node B. In the R7 cell, the 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 are supported. After the handover, a MAC layer and/or an RLC layer are reconfigured or reset based on functionality supported by the target Node B.

EFFECT: reduced loss of quality and data during handover.
