| 发明名称 | Method and apparatus for handling handover procedure | ||
| 摘要 | The present invention provides a method for handling a handover procedure for a Radio Resource Control (RRC) layer 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) layer of the UE when receiving an RRC Connection Reconfiguration message for triggering the handover procedure, applying a new security configuration to the PDCP layer if the RRC Connection Reconfiguration message includes an information element (IE) for providing the security configuration, and requesting a Medium Access Control (MAC) layer of the UE to initiate a random access procedure for the handover procedure. | ||

| 主权项 | 1. A method for handling a handover procedure for a Radio Resource Control (RRC) layer in a user equipment (UE) of a wireless communication system, the method comprising: indicating occurrence of a handover procedure to a Packet Data Convergence Protocol (PDCP) layer of the UE when receiving an RRC Connection Reconfiguration message for triggering the handover procedure; applying a new security configuration to the PDCP layer if the RRC Connection Reconfiguration message comprises an information element (IE) for providing the security configuration after indicating occurrence of the handover procedure to the PDCP layer; and requesting a Medium Access Control (MAC) layer of the UE to initiate a random access procedure for the handover procedure after applying the new security configuration to the PDCP layer. | ||
