Handover initiation and decision criteria for the fourth generation radio-mobile networks

Despite qualms about its early success after years of promise, 2,5G and 3G technologies will show the best long-term results when it comes to wireless data access. However, 4G and Wi-Fi technologies will also grow as high-speed wireless data systems become varied and operators choose an air-interface matching the varied wants and needs of desired audiences. Digital fourth-generation IP-based high-speed cellular systems will account for 14% of total mobile and portable wireless data revenues in 2007 and 50 million subscribers by year-end 2007. Realization of seamless handovers to the best network section while considering QoS and AAAC (authentication, authorization, accounting and charging) calls not only for seamless handover protocols, but also intelligent handover decision strategies. In this paper is analyzed a handover decision strategy in mobile All-IP networks to support seamless handover scenarios.
