Abstract

Because each resource in LTE-Advanced system and network's shapes such as bandwidth, error rate change variably, it is judged that it is impossible to control service continuity with procedural, artificial, and static control method applied to the existing voice service. This research suggests a QoS management mechanism to support the service continuity effectively based on policy control. It means a method in which a subscriber's terminal collects information about its current condition and base station around, and a base station, through the data collected by monitoring inner or adjacent base station, shares related data and converges, controlling service continuity on its own.

LTE-Advanced 망을 형성하는 리소스 및 망의 형상(대역, 에러율 등)들이 가변적으로 변하기 때문에 기존 음성서비스에 적용된 절차적이고, 인위적이고, 정적인 제어방식으로는 제어가 불가능하다고 판단하고 있다. 본 연구에서는 정책제어를 기반으로 서비스 연속성을 효과적으로 지원하기 위한 QoS 관리 체계를 제안하고자 한다. 가입자 단말기는 자신의 현재 상태 및 주변 기지국 정보를 수집하고, 기지국은 내부 및 인접한 기지국 모니터링으로 수집된 정보를 통하여, 관련 제어데이터를 공유하고 이를 종합 분석하여 서비스 연속성을 자체적으로 조절/제어하는 방법을 제시한다.
