    摘要: A method and system for improving a call drop caused by a Radio Link Failure (RLF) before handover triggering in a mobile communication system are provided. The method of improving the call drop caused by the RLF in the mobile communication system includes detecting an RLF occurring before handover triggering (RLF_before_HO), generating one of an RLF_before_HO-dependent statistics and an RLF_before_HO-dependent log file, transmitting the one of the RLF_before_HO-dependent statistics and the RLF_before_HO-dependent log file to a serving Base Station (BS), and updating a Neighbor Relation Table (NRT) and optimizing a handover parameter using the one of the RLF_before_HO-dependent statistics and the RLF_before_HO-dependent log file.

    摘要: An apparatus and method for handover in a mobile communication system enables a Mobile Station (MS) to perform a normal handover without performing an unnecessary handover. A Base Station (BS) apparatus capable of preventing an unnecessary handover includes a handover manager. The handover manager receives handover information, including information about at least one cell through which an MS has passed, from a neighbor cell to determine whether the MS has performed an unnecessary handover. If it is determined that the MS has performed an unnecessary handover, the handover manager notifies the occurrence of the unnecessary handover by the MS to the neighbor cell.

    摘要: Disclosed is a method and apparatus for transmitting data of a Radio Link Control (RLC) layer in a mobile communication system. Before an RLC SDU stored in a transmission buffer is discarded, a status report for checking a reception status of a receiving side is requested by a polling trigger either when transmission of the RLC SDU has not been completed, or when an RLC SDU discard timer for the RLC SDU approaches the expiration time, thereby enhancing the data transmission performance of the RLC layer.
