Packet scheduling algorithms for providing QoS on UMTS downlink shared channels
Enrico Natalizio, S. Marano, Antonella Molinaro · 2006
generation cellular systems is one of the keys for the commercial success of these networks. Radio Resource Management (RRM) is the way to provide users with QoS. The main “building blocks ” of the RRM layer are: Call Admission Control (CAC), packet classification, and packet scheduling. This paper focuses on the packet scheduling for the interactive and background QoS traffic classes delivered over the UMTS Downlink Shared Channel (DSCH). It proposes and analyses five new schemes of scheduling and a new priority allocation parameter. Simulations are executed in order to compare performances in terms of throughput, response time and average page-download time.
