Abstract

In this paper, the design issues of a coverage-based CRRM strategy are studied to support voice services in a heterogeneous UMTS/GSM environment which distribute the traffic load by controlling the effective UMTS coverage through a predefined pathloss threshold. Comparing with the conventional Load Balancing strategy, the proposed coverage-based CRRM gives a better performance in terms of voice capacity at the expense of extra inter-system handovers. The effects of compress mode operation and mobility on system performance and pathloss threshold selection are also studied in details to refine the CRRM.
