Network efficiency for wireless Internet access

It is foreseeable that more and more data traffic generated by interactive application will be carried by the current mobile cellular networks, which is currently dominated by circuit based voice calls. In this paper we propose to use network efficiency, which considers both revenue and network cost as criteria to dimension bandwidth between real-time service and best effort service. Optimized network efficiency reserves some bandwidth for best-effort services, while real-time traffic enjoys preemptive priority beyond the reserved bandwidth. The reservation for best-effort traffic has special significance for users accessing the Internet via a radio link.
