우리는 셀룰러 네트워크와 WLAN(무선 근거리 통신망) 통합을 위한 두 가지 수직 핸드오프 방식, 즉 통합 서비스 기반 핸드오프(ISH)와 통합 서비스 기반 핸드오프(ISHQ)를 제안합니다. 통합 셀룰러/WLAN 네트워크의 기존 핸드오프 방식과 비교하여 제안된 방식은 음성 및 데이터 서비스의 다양한 기능, 허용된 통화에 대한 동적 정보, 사용자 이동성 및 양방향 수직 핸드오프와 같은 보다 포괄적인 시스템 특성 세트를 고려합니다. 제안된 방식에서는 CDMA(코드 분할 다중 접속) 셀룰러 네트워크와 IEEE 802.11e WLAN이 고려됩니다. 다차원 마르코프 체인을 사용하여 통합 네트워크를 모델링하고 음성 및 데이터 서비스에 대한 주요 성능 측정값을 도출합니다. 핸드오프 음성 통화의 우선순위를 지정하는 임계값 및 대기열 크기와 같은 중요한 시스템 매개변수가 최적화됩니다. 수치 결과는 제안된 ISHQ 방식이 음성 및 데이터 서비스에 대한 최고의 서비스 품질(QoS) 프로비저닝을 통해 전체 대역폭 자원의 활용을 극대화할 수 있음을 보여줍니다.

Abstract: We propose two vertical handoff schemes for cellular network and wireless local area network (WLAN) integration: integrated service-based handoff (ISH) and integrated service-based handoff with queue capabilities (ISHQ). Compared with existing handoff schemes in integrated cellular/WLAN networks, the proposed schemes consider a more comprehensive set of system characteristics such as different features of voice and data services, dynamic information about the admitted calls, user mobility and vertical handoffs in two directions. The code division multiple access (CDMA) cellular network and IEEE 802.11e WLAN are taken into account in the proposed schemes. We model the integrated networks by using multi-dimensional Markov chains and the major performance measures are derived for voice and data services. The important system parameters such as thresholds to prioritize handoff voice calls and queue sizes are optimized. Numerical results demonstrate that the proposed ISHQ scheme can maximize the utilization of overall bandwidth resources with the best quality of service (QoS) provisioning for voice and data services.
