Characteristics of the UMTS “Internet on Air” Network
! End-to-End IP, Internet compliant (IETF, W3C, DMTF).
!
Enhancements where necessary to enable mobility. Design is based on IPv6.
! Support end-to-end multi-media communication
over heterogeneous networks.
! Use TCP/IP as a common framework for multimedia communication.
! Enable global mobility.
! Access over many different networks (wireless & wireline).
! Interworking with existing (legacy) networks.
! Provisions for allocation and management of network resources.
! Voice is only one possible application, although an important benchmark.
Clear split between transport network and applications.
