Abstract

The future wireless network is expected to be a heterogeneous system, which integrates different Radio Access Technologies (RATs) through a common platform. A major challenge arising from this heterogeneous network is Radio Resource Management (RRM) strategy. Common RRM (CRRM) has been proposed in the literature to jointly manage radio resources among a number of overlapped RATs in an optimized way. Currently, the RAT selection algorithm is one of the key research areas of CRRM. This paper studies RAT selection algorithms in co-located UMTS/GSM networks. In this paper, a three complex algorithm called IN*VG*Load is proposed based on improvements on the IN*VG algorithm. The simulation results show that the IN*VG*Load algorithm can optimize the system performance in highly loaded combined UMTS/GSM networks. A new algorithm suitable for low to medium loaded UMTS/GSM networks is also proposed and simulation results are presented in this paper.
