속도 적응 가변 시간-기준 위치관리 기법 ( Adaptive time-based location update using fuzzy logic )

This paper introduces an adaptive time-based location update scheme that dynamically determines when to perform location update based on moving distance of mobile station and incoming call arrival probability using fuzzy logic. Comparison with other schemes demonstrate that proposed scheme adapts well to the environment where the characteristics of mobility pattern of mobile station is changed all the time, and reveals better performance in the aspect of network signaling load.
