Mobile devices have evolved remarkably over the last decade and are now being utilized to access much broader range of internet applications. Moreover, their capability to simultaneously run many applications has significantly transformed the traffic characteristics of mobile networks. Quality of service (QoS) is a fundamental component associated with these applications and network should be able to support multiple QoS requests from the same user at same time. This requires complex buffer management and simultaneous scheduling of resources to multiple users with multiple services. In this paper, we propose a framework with pre-processor for MAC-layer scheduler including two-dimensional buffer management (users  services) that enable more efficient allocation of resources to users running multiple internet applications in parallel. The framework will enhance the performance of existing scheduling algorithms by increasing the resolution of scheduling. A comparative analysis of traditional scheduling algorithms is provided to show the gains of proposed framework.
