The paper presents a performance study of two algorithms for dynamic allocation of the dedicated channels (DCH) in UMTS over the air interface, namely least recently used (LRU) algorithm and an adaptive algorithm. The algorithms are designed to efficiently share the dedicated channels among users whose traffic patterns are characterized by bursty packet transfers followed by long inactivity periods. Specifically, Web browsing, FTP and email applications were considered in order to evaluate the performance of the above mentioned resource allocation algorithms in the context of bursty traffic with relaxed delay constraints and In the presence of delays introduced by the backhaul network
