This paper presents an adaptive bandwidth management technique to improve the transmission efficiency of a high speed downlink packet access (HSDPA) network by adaptively allocating radio access network resources. The radio access network resources are allocated based on the air interface demand. The proposed bandwidth management technique is evaluated by an analytical and a simulation model. Both analytical and simulation results show that the proposed algorithm improves the Iub link utilization, and keep high the HSDPA air interface resource utilization by jointly optimizing the resource allocation processes.
