Abstract
In an integrated terrestrial-satellite system exploiting W-CDMA air interfaces, such as the future UMTS, we conduct an in-depth research on radio resource management techniques for the support of multimedia applications with quality guarantees. The multi-bearer transmission coupled with a multitier coverage has the potentiality of allowing the effective exploitation of the radio resources while guaranteeing an adaptive quality to all end-users. Nevertheless, it still remains to be clearly understood how good they cope with typical features of next-generation multimedia cellular systems, such as soft handoff. This paper tries to contribute to this issue by reporting the lessons learned during a performance assessment study on a simulation platform of a UMTS system.
