Abstract

With rapid technological advances being made in the area of wireless communications it is expected that, in the near future, mobile users will be able to access a wide variety of services that will be made available over future high-speed networks. The quality of these services in the high-speed network domain can be specified in terms of several QoS parameters. In this paper we identify two new QoS parameters unique to the mobile environment - guarantee of seamless service and ensuring graceful degradation of service in situations where user demands exceed the network's capacity to satisfy them. A network architecture and a suite of transport level services are proposed that enables these QoS parameters to be satisfied.
