Support of mobile multimedia over radio for a range of QoS and traffic profiles

Future 3rd generation mobile systems, such as UMTS and IMT-2000, will provide a range of flexible transport characteristics. These systems will enable multimedia services to be offered to mobile users but transport over radio will limit QoS. The requirements of mobile multimedia are considered and compared to the capabilities of ATM networks, IP networks and radio characteristics. The radio interface and access network being developed for UMTS, supported by ATM and IP are described for the support of mobile multimedia.
