초록

무선 망에서 단말기를 호출하기 위한 일차 페이징 지역인 LAI 의 설계는 페이징 채널의 트래픽 생성과 매우 밀접한 관련이 있다. 이 논문에서는 페이징 채널을 통과하는 호 제어 및 부가 기능 메시지를 통해 IS-95 CDMA 표준에 따른 페이징 채널이 용량을 실제 운용 상황에서 발생하는 트래픽 자료를 바탕으로 분석하고자 한다. 이 분석은 페이징 채널이 처리할 수 있는 LAI 의 적정 용량(Engineered Capacity)을 통하여, 기지제어국 및 기지국 시스템의 용량에 따른 망 계획의 중요한 기준을 제공한다.

The design of LAI(Local Area Identifier), the first paging area for searching the mobile terminal has a close relation with the performance of paging channel in CDMA cellular network. This paper discussed the performance of the forward channel of IS-95 CDMA standard, known as the paging through the related messages such as call control message, channel assignment message, etc. Modeling and simulation work were conducted to quantify the performance of paging channel in terms of traffic handling capacity and blocking levels. The results shown are based on a specific system call model based on the operating system of cell cite. This serves as illustrative guidelines for the proper engineering of common control channel, which has a major impact on the overall performance of cellular network.
