In this paper we introduce universal mobile channels, a le communications abstraction that enables users and service providers to program application-speci c adaptive mobile services into a cellular Internet. Universal mobile channels are capable of supporting distinct adaptive quality of service control and mobility management services over the same cellular access network infrastructure. Built on a splitlevel adaptation control scheme that operates at the application and network levels, universal mobile channels o er a set of well de ned open programmable interfaces to actively exploit the intrinsic scalability of adaptive mobile applications in cellular IP networks. Universal mobile channels are fully programmable and expose interfaces that include: i utility curves, which capture the adaptive nature of mobile applications in terms of the range of bandwidth over which they can successfully operate; ii adaptation policy, which enables adaptive mobile applications to program per-...
