Propomos dois esquemas de transferência vertical para integração de redes celulares e redes locais sem fio (WLAN): transferência integrada baseada em serviços (ISH) e transferência baseada em serviços integrados com capacidades de fila (ISHQ). Comparados com os esquemas de handoff existentes em redes integradas celulares/WLAN, os esquemas propostos consideram um conjunto mais abrangente de características do sistema, tais como diferentes funcionalidades dos serviços de voz e dados, informação dinâmica sobre as chamadas admitidas, mobilidade dos utilizadores e handoffs verticais em duas direcções. A rede celular de acesso múltiplo por divisão de código (CDMA) e a WLAN IEEE 802.11e são levadas em consideração nos esquemas propostos. Modelamos as redes integradas usando cadeias de Markov multidimensionais e as principais medidas de desempenho são derivadas para serviços de voz e dados. Os parâmetros importantes do sistema, como limites para priorizar chamadas de voz de transferência e tamanhos de fila, são otimizados. Os resultados numéricos demonstram que o esquema ISHQ proposto pode maximizar a utilização dos recursos gerais de largura de banda com o melhor provisionamento de qualidade de serviço (QoS) para serviços de voz e dados.

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.
