Seamless multimedia services over all-IP based infrastructures: the EVOLUTE approach

摘要: The increasing amount of roaming Internet users in combination with the evolution IP-based applications has created a strong demand for wide-area, broadband access to number IP multimedia services. Wireless LANs can complement next-generation cellular networks, by offering cost-efficient, wireless data solution hot spot areas. By combining wide coverage systems speed and capacity advantages LANs, make most out communication. Towards this direction, IST project EVOLUTE implements an all network infrastructure aiming provide seamless services users. addresses attempts resolve issues, such as, multilayer mobility management, vertical handoffs, fast scalable Authentication-Authorization-Accounting (AAA) mechanisms, ubiquitous service provisioning among heterogeneous environments. User trials have been defined VoIP selected others, test validate capabilities architecture.
