Due to the growing popularity of high data-rate multimedia services such as streaming, gaming, and video conferencing using mobile devices, providing strict QoS support in cellular networks is becoming crucial. Moreover, differentiated service requirements and service plans promote service providers to enforce their own policies aligned with their goal of maximizing revenue in meeting these QoS requirements. While network service providers may desire to impose operational policies on the packet schedulers, existing schedulers are not capable to deal with such challenges due to many factors including time varying channel conditions, constraints on the total transmit power allocated to forward links i.e., base station to mobile stations, and lack of policy abiding fast scheduling algorithms.
