Abstract

A smart phone and the number of wireless terminals are mobile-to the nature of the AP mobility are many call transfer between wireless terminals and AP (Access Point). Each wireless terminal that is the call processing process for each is relatively large to cause the wireless traffic, and a factor that inhibits the efficient use of the radio band on the AP. In this paper, we use the power intensity threshold and threshold timer of the AP received by the mobile station to reduce the amount of switching traffic between the AP's cause and traffic generation factors between the wireless device and the AP that can effectively utilize the radio traffic from the AP the measures proposed. The proposed method and the conventional method is improved by simulation to handle the amount of radio traffic from the AP it was confirmed that it is possible to effectively utilize the whole of the radio band.

스마트폰과 많은 무선단말기들이 이동성의 특성상 AP간 이동하게 되어 무선단말들과 AP(Access Point)간 많은 호 절체가 이루어지게 된다. AP에서 각 무선단말기마다 처리되는 호 처리는 상대적으로 많은 무선트랙픽을 유발하여 무선대역의 효율적인 활용을 저해하는 요인이 되고 있다. 따라서 본 논문에서는 무선단말기와 AP간의 트래픽 발생요인이 되고 있는 AP간 호 절체 트래픽양을 줄이기 위해서 무선단말기에 수신되는 AP들의 전력세기임계치와 임계타이머를 사용하여 AP에서 효과적으로 무선트랙픽을 활용할 수 있는 방안을 제안하였다. 제안된 방식과 기존의 방식을 시뮬레이션을 통하여 AP에서 처리하는 무선트래픽 양이 개선되어 전체적으로 무선대역의 활용을 효율적으로 할 수 있었다.
