Current cellular networks are often overloaded by Smartphone traffic, while the users' Quality of Service (QoS) demands are not met. To cope with this problem, the authors demonstrate a new radio resource management approach. With Context-Aware Resource Allocation, the base station's scheduler: observes Context Information (CI) from the user's environment and utilizes this knowledge for an efficient throughput-delay tradeoff. After introducing their framework for accessing CI from the handheld's applications and operating system, they use time-utility functions to develop a practical scheduling algorithm. Studying this heuristic under various traffic assumptions shows that their context-aware scheduler can support three times the load of proportional fair scheduling, at equal capacity and utility.
