The introduction of Common Radio Resource Management (CRRM) facilitates the coordination of multiple overlapped Radio Access Technologies (RATs). A Network Controlled Cell Breathing (NCCB) RAT selection algorithm is proposed in the literature for combined GSM/UMTS networks. The setting of a proper path loss threshold is a key issue in the NCCB algorithm. In this paper, the relationship among overall downlink data throughput, throughput fairness and path loss threshold is studied. It is found that in some cases, an optimum path loss threshold value can be found to achieve better performance in terms of both overall throughput and throughput fairness. However, in other cases, a tradeoff has to be made between the overall throughput and the throughput fairness.
