Abstract

This paper focuses on the analysis of 3G mobile communications systems in scenarios with non-uniformly distributed traffic. Special attention is paid to the impact of hotspots on radio resource management (RRM) strategies such as uplink admission control. Users path loss is examined for different hotspot configurations, and degradation suffered by users in terms of BLER is observed by varying hotspot density and distance from base station. Results reveal that the performance of the system in the uplink depends on traffic distribution and that some parameters of RRM strategies should be adapted to these varying situations.
