Abstract

As a result of the prevalence of smartphone, various mobile services became faster by LTE networks. Because many mobile devices are used more wireless services, heavy signaling traffic for authentication could be generated. Authentication is an important factor in wireless networks to identify devices; it is the start of wireless networks. This paper analyzes previous patterns for more effective authentication in accessing of another external networks. We propose a fast authentication scheme for minimizing of signaling cost between the authentication server and external networks. And we calculate the rate of authentication occurrence in LTE networks using mathematical modeling as well as the change of signaling cost for authentication in various network environments. Finally, we calculate the optimized number of authentication data and show the effectiveness for authentication signaling costs.

현재 많은 스마트폰의 보급으로 LTE 네트워크를 통해 다양하고 빠른 모바일 서비스를 하게 되었다. 이에 수많은 모바일 기기들이 이전보다 더 많은 무선서비스를 이용하게 되고 그에 따른 수많은 인증 시그널링이 발생하게 된다. 이러한 무선네트워크에서 인증은 무선기기를 식별할 수 있는 중요한 역할을 하며 무선네트워크의 시작이기도 하다. 그래서 본 논문에서는 이전에 인증이 발생된 패턴을 분석하여 또 다른 외부 네트워크로 접근할 때 이전 보다 효과적인 인증을 수행한다. 그래서 LTE 네트워크에서 외부 네트워크와 인증서버 사이의 시그널링 비용을 최소화하여 빠른 무선 인증 서비스를 제안한다. LTE 네트워크에서 인증이 발생되는 비율을 수학적 모델링을 이용하여 계산하였고, 이를 다양한 환경에서 인증 시그널링 비용의 변화를 계산하였다. 본 논문에서 제안한 최적 인증 데이터의 수를 계산하여 이전 보다 효율적인 인증 시그널링 비용이 발생함을 보인다.
