A Location-Aware Resource Reservation Algorithm with User Class Differentiation in WCDMA

This paper proposes and evaluates a radio resource reservation algorithm that takes advantage of location-aware techniques in order to facilitate handovers in a WCDMA system, specially for users following straight trajectories. The mobility characteristics of these users may provide certain information about the instant of time when they require a handover process. The proposed resource reservation algorithm takes into account the user location information in order to manage the available radio resources in a more efficient way. The proposed algorithm optimizes the existing trade-off between the blocking probability of new connection requests and the dropping probability of users in handover. This optimization is obtained by minimizing the system grade of service (GoS). Moreover, the algorithm includes a prioritization of business users over consumer users. The obtained results are compared to a reference algorithm and the impact on the most important performance indicators has been analyzed, including the influence of call duration and service bit rate
