Abstract: Provided are a paging method and an apparatus thereof for User Equipment (UE) in a broadband wireless communication system. In the method, a paging message is received from a macro base station. Whether there exists an accessible femto base station inside a service area of the macro base station is determined. When there does not exist the accessible femto base station inside the service area of the macro base station, the UE responds to the paging message of the macro base station. When there exists the accessible femto base station inside the service area of the macro base station, the UE waits for a paging message to be received from the femto base station.

Abstract: 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.

Abstract: Disclosed is a method for controlling activation/deactivation of two kinds of operation modes of an MMMB mobile terminal during handover between different types of systems. To control the activation/deactivation, a system controller instructs the mobile terminal to activate/deactivate the operation modes or provides activation/deactivation conditions to the mobile terminal. In particular, when the mobile terminal in communication is situated in a border cell neighboring a target system, the mobile terminal activates target system-related modules and then performs handover into the target system according to predetermined conditions after the passage of a predetermined time period. Such a handover method minimizes time required for performing handover, prevents deterioration of call quality during the handover, and saves power consumption of the mobile terminal.

Abstract translation: 公开了一种在不同类型的系统之间切换期间控制MMMB移动终端的两种操作模式的激活/去激活的方法。 为了控制激活/去激活，系统控制器指示移动终端激活/去激活操作模式或向移动终端提供激活/去激活条件。 特别地，当通信中的移动终端位于与目标系统相邻的边界小区中时，移动终端激活目标系统相关模块，然后根据预定时间段之后的预定条件执行到目标系统的切换。 这种切换方法使得执行切换所需的时间最小化，防止切换期间的呼叫质量恶化，并且节省了移动终端的功耗。

Abstract: 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.
