    • An apparatus and a method for performing handover in a mobile communication system are provided to easily discriminate a mobile station signal by enabling base stations to respectively share uplink channel assignment information and inherent information of a mobile station, and enable neighboring base stations to measure uplink signal quality of the mobile station and report the measured quality to a serving base station, so that the serving base station can more efficiently determine handover of the mobile station in consideration of uplink and downlink channel states. A method where a serving base station performing communication with a mobile station determines handover of the mobile station in a mobile communication system, comprises the following steps of: reporting channel assignment information and inherent information of the mobile station to neighboring base stations if a value, measured in consideration of uplink and downlink channel states, is lower than a preset threshold value(308,310); receiving uplink signal quality of the mobile station measured by the neighboring base station, and determining whether there is a target base station to which the mobile station will perform the handover(312,314); and if so, notifying the fact that the handover will be performed to the target base station and the mobile station(316).
    • 提供了一种用于在移动通信系统中执行切换的装置和方法,用于通过使基站能够分别共享上行链路信道分配信息和移动台的固有信息来容易地识别移动台信号,并使相邻基站能够测量上行链路信号 移动站的质量并将测量的质量报告给服务基站,使得服务基站可以考虑到上行链路和下行链路信道状态更有效地确定移动台的切换。 一种与移动台进行通信的服务基站确定移动通信系统中的移动台的切换的方法,包括以下步骤:向相邻基站报告所述移动台的信道分配信息和固有信息, 考虑到上行链路和下行链路信道状态测量,低于预设阈值(308,310); 接收由所述相邻基站测量的所述移动台的上行链路信号质量,以及确定是否存在所述移动台将执行所述切换的目标基站(312,314)。 并且如果是,则通知切换将被执行到目标基站和移动台(316)的事实。
