Abstract

In order to support quickly increasing mobile traffic and deal with various types of users of wireless mobile systems under overlay convergent cognitive networking environments, it is highly required to improve the performance and the capability of the wireless access networks. With distributed antennas and distributed processors, it is possible for mobile terminals (MTs) to monitor interference and control system effectively to minimize mutual interference among users and cells. Virtual cell changes as the MT moves or the environment changes, so no handoff is needed in connections with base station hotelling. In this paper, the characteristics of wireless distributed systems under the overlay convergent networks will be investigated.

중첩 융합 네트워크 환경 하에서의 무선 이동통신시스템의 성능개선이 급격히 증가하는 무선 트래픽의 처리를 위해 매우 중요한 이슈로 떠오르고 있다. 그러므로 단말기의 기능성이 좋아짐에 따라 스마트한 지능을 기반으로 자원의 효과적 활용에 적합한 개별 이종네트워크의 특성분석과 특성을 반영하는 시스템측면의 최적화가 매우 중요하다고 할 수 있다. 본 논문에서는 기지국의 소형화와 지능화가 진행되는 가운데 기지국 hotelling과 같은 기지국 집중화를 통한 통합적 최적화가 가능하므로 이에 대응한 이중 가상 셀 시스템에 대해 살펴보고 활용도 측면의 특성을 분석하였다.
