For any IMS (IP Multimedia Subsystem) or pre-IMS combined network, the key enabling function for seamless mobility and service continuity among a variety of mobile/wireless access technologies supporting IP connectivity is the handover. HURRICANE focuses on the key RTD challenge to investigate, design, implement, validate and propose for standardisation, inter-system handover operations among various radio cooperative networking environments (3G, WLAN, WIMAX and DVB) that are going to formulate future/near future business cases for both broadcasters and telecom operators in the context of a Fixed-mobile convergence (FMC) communications environment. HURRICANE is going to assist ETSI TISPAN, 3GPP, IEEE 802.21, and DVB efforts to formulate an optimized handover operational framework towards the formulation of next generation networks where Europe has to obtain a key leadership role.
