Abstract

In this paper we suggest a call admission control (CAC) algorithm for high speed downlink packet access HSDPA UMTS systems. In this algorithm the user requesting admission is gradually admitted into the system. This is done by setting a back-off factor limiting the new user’s throughput. The back-off factor is gradually decreased leading to a gradual increase in the new user’s throughput until it is fully integrated into the system. The back-off factor works on protecting the active links in a way that their rates do not drop below a guaranteed quality of service (QoS) level.
