이동통신망에서 영역기준 위치등록 방법의 개선 및 성능평가

초록

Many strategies have been proposed to reduce mobility management cost. Among them, in this paper, we study three schemes of zone-based registrationthat have been adopted by most of mobile systems. These special schemes are referred to as the single-zone-based registration (SZR), the two-zone-based registration (TZR) and the two-zone-based registration with outgoing call (TZRC) respectively. We propose a mathematical model to evaluate the performance of TZRC in order to compare with those of SZR and TZR. Numerical results show that TZRC outperforms not only SZR but also TZR in most cases.
