Abstract

As the spread of smart devices that service variety of content, limited mobile terminal channel assignment problem has intensified. In the channel assignment in mobile networks mobile switching center at the request belongs to each base station allocates the channel to the mobile station. This effectively allocate the limited channels of various methods have been proposed for, in this case a hybrid channel allocation using genetic algorithms UHGA (Universal Hybrid Channel Assignment using Genetic Algorithm) in rural areas or urban areas, such as universal network applied to a variety of environments that the efficiency is verified through simulation.

스마트 기기의 보급 확대로 다양한 콘텐츠를 서비스하는 이동 단말기의 한정된 채널 할당 문제가 심화되고 있다. 이동통신망에서는 이동국에서 채널할당 요청이 있을 때 교환국에서 각 기지국에 속한 이동국에 채널을 할당한다. 이 때 한정된 채널을 효과적으로 할당하기 위한 다양한 방식들이 제안되고 있는데, 여기서는 하이브리드 채널 할당에 유전 알고리즘을 이용한 UHGA(Universal Hybrid Channel Assignment using Genetic Algorithm)이 농촌 지역이나 도심 지역과 같은 다양한 환경의 범용 망에 적용되어 효율성이 있음을 시뮬레이션을 통해 검증한다.
