A QoS Concept for Packet Oriented S-UMTS Services

An approach by the IST FUTURE project to make packet based multimedia services feasible in a satellite based UMTS environment. Different QoS guaranteeing mechanisms are presented exploiting the terrestrial UMTS specification in order to achieve an integrated TS -UMTS. The focus is set on mechanisms for the access network, while the core network is only theoretically investigated in order to give an end-to-end QoS approach. For the access network, based on the UMTS specifications, algorithms for Connection Admission Control, Scheduling, Active Set Handling and Measurement Control have been proposed for an SUMTS environment
