    • An apparatus and method for estimating a cell load in a wireless communication system are provided. The apparatus includes a ranging response counter, a load estimator, an FA handover determiner, a data rate determiner, and a handover determiner. The ranging response counter counts the number of ranging response messages that are received during one period of periodic ranging. The load estimator estimates a cell load on the basis of the number of the ranging response messages. The FA handover determiner determines an FA handover on the basis of the cell load from the load estimator. The data rate determiner controls a data rate of a service on the basis of the cell load from the load estimator and requests the controlled data rate to the system. The handover determiner controls handover parameters on the basis of the cell load from the load estimator.
    • 提供了一种用于估计无线通信系统中的小区负载的装置和方法。 该装置包括测距响应计数器,负载估计器,FA切换确定器,数据速率确定器和切换确定器。 测距响应计数器计数在周期性测距的一个周期期间接收的测距响应消息的数量。 负载估计器基于测距响应消息的数量来估计小区负载。 FA切换确定器基于来自负载估计器的小区负载来确定FA切换。 数据速率确定器基于来自负载估计器的小区负载来控制业务的数据速率,并将受控数据速率请求给系统。 切换确定器基于来自负载估计器的小区负载来控制切换参数。
