Abstract
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.
