ABSTRACT:
In the area of mobile systems, things usually are discussed 10 years in advanced. So for the aim of beginning 4G around 2010, it is the time to discuss 4G now. This paper describes architecture for heterogeneous wireless-wired networks. This architecture applies an “all-IP” paradigm, with embedded mobility of users and is able to provide quality of service per-user and per-service. On the way to 4G-system architecture, major issues like requirements, adaptability are considered.
