Abstract

The present invention provides a method for handling a handover procedure and a communication device thereof, which are used in a Radio Resource Control (RRC) unit in a user equipment (UE) of a wireless communication system,. The method includes steps of indicating occurrence of a handover procedure to a Packet Data Convergence Protocol (PDCP) unit of the UE when receiving an RRC Connection Reconfiguration message for triggering the handover procedure, applying a security configuration to the PDCP unit when the RRC Connection Reconfiguration message includes an information element (IE) for providing the security configuration, and requesting a Medium Access Control (MAC) unit of the UE to initiate a random access procedure for the handover procedure.

Description

technical field [0001] The present invention refers to a method for processing a handover procedure and its communication device, especially a method for correctly processing a handover procedure in a radio resource control layer of a client of a wireless communication system and its communication device. Background technique [0002] The Long Term Evolution (LTE) wireless communication system is an advanced high-speed wireless communication system built on the third generation mobile communication system (such as the Global System for Mobile Telecommunications), which only needs to support Packet Switched transmission, and the radio link control (Radio Link Control, RLC) layer and the medium access control (Medium Access Control, MAC) layer can be integrated in the same communication network unit, such as the base station (Node B), without having to be located separately Among base stations and radio network controllers (RNCs), the system architecture is relatively simple. ...
