摘要: High Speed Downlink Packet Access (HSDPA) is being increasingly deployed to enhance UMTS Radio Networks. Scheduling of Node B (base station) buffered user data for trans- mission over a shared radio channel key HSDPA functionality which enables queue management techniques be utilized improve QoS provisioning mixed 'multimedia' services. Thus, we have previously proposed and studied Time-Space Priority (TSP) buffer scheme control in B. In this paper the extended incor- porate threshold-based rate mechanism provides flow between RNC entities Iub interface performance non-real-time (NRT) streams multimedia flow. Mathematical simula- tion models are developed comparative analysis with pre- viously TSP lacking control. The results demonstrate improvement achievable joint implementation mechanism(s).
