Requirements for personal mobility in FPLMTS/UMTS: a view point from the user´s expectations

The goal of the paper is to discuss which mobility services need to be offered to FPLMTS/UMTS users. In fact, personal mobility needs depend on user types and mobility patterns. To define mobility services for FPLMTS/UMTS users, two approaches are possible: the first one is the personal communicator, a small terminal combining a multitude of applications and services that allows you to make and receive calls everywhere; the second one concerns the Universal Personal Telecommunication service which enables users to access telecommunication services on the basis of a unique personal network transparent UPT number across multiple networks at any terminal. These two approaches are discussed from the user point of view
