Providing QoS and Rate Limiting for WiMAX Mobile Hotspots based on Policy and Charging Control Architecture
A hotspot offers Internet access over Wi-Fi through the use of a router connected to a link to an internet service provider. If the link is wireless, e.g., WiMAX, the hotspot becomes mobile. Under such a heterogeneous network, it is challenging to provide QoS and/or to control data rate. In this paper, the authors design and implement a policy server for commercial WiMAX mobile hotspots based on Policy and Charging Control (PCC) architecture defined in WiMAX Forum. The paper investigates a suitable QoS configuration including scheduling type.
