摘要
The foreseen mass diffusion of mobile communication services will require the identification of suitable resource management strategies to utilize efficiently the available spectrum. This paper refers to high-mobility cellular systems and carries out a performance evaluation for different channel assignment techniques that belong to the following classes: Fixed Channel Allocation (FCA), or Dynamic Channel Allocation (DCA). Suitable handoff prioritization techniques have been considered to obtain a high quality of service; in particular, the queueing of handoff requests and the use of guard channels have been investigated. The resource management techniques have been compared in terms of the following parameters: the call blocking probability, the call dropping probability, the probability of unsuccessful call and the average number of channel rearrangements per call. The joint use of DCA, guard channels, queueing of handoff requests and channel rearrangements has shown promising results for the management of both new call attempts and handoff requests.
