Method and apparatus for handling handover procedure

Abstract

The present invention provides a method for handling a handover procedure for an RRC layer in a UE of a wireless communication system. The method includes steps of indicating occurrence of a handover procedure to a PDCP layer of the UE when receiving an RRC Connection Reconfiguration message for triggering the handover procedure (402), applying a new security configuration to the PDCP layer if the RRC Connection Reconfiguration message includes an IE for providing the security configuration (404), and requesting a MAC layer of the UE to initiate a random access procedure for the handover procedure (406).
