HANDOVER METHOD AND APPARATUS IN WIRELESS COMMUNICATION SYSTEM |
摘要 |
The present disclosure provides a method for correcting an error caused by Hyper Frame Number (HFN) and Packet Data Convergence Protocol Sequence Number (PDCP SN) mismatch between a user equipment and base station when the user equipment fails in handover between cells in a wireless communication system. In addition, the present disclosure provides a handover procedure for a user equipment performing handover from a macro cell to a Closed Subscriber Group (CSG) cell shared by multiple operators in a wireless communication system. The present disclosure enables a user equipment and base station to perform communication without a malfunction after handover failure. For handover from a macro cell to a CSG cell shared by multiple operators, the present disclosure enables a user equipment to perform handover to an accessible cell. |
