On Improving Perceived User Throughput in Heterogeneous HSPA, GERAN and WLAN Scenarios

This paper considers a heterogeneous radio access network scenario where different radio access technologies (RATs) are jointly managed. Different RAT selection algorithms are evaluated for both downlink and uplink transmissions, where the basic strategies of the algorithms are based on operator QoS policies. The total perceived system throughput gain from common radio resource management (CRRM) compared to a manual RAT selection scenario is analysed using three different examples of algorithms based on operator's policies for RAT selection.
