Abstract: In the context of a dynamic adaptation of a transmission data rate of a terminal device in a wireless communication network, predefined transmission profiles that correspond to respective data rates are associated respectively with reception sensitivities. A server performs an optimization of said transmission data rate in successive stages, and decides to switch to a new stage according to a frame delivery rate with respect to a predefined threshold. The server selects the transmission profile to be applied by the terminal device while keeping at least a predefined margin, dependent on the stage at which the operation is performed, between received signal strength indication and reception sensitivity corresponding to said transmission profile.

Abstract: A novel method of calculating and enforcing user traffic parameters on an ATM network is disclosed. The method of the present invention provides very accurate calculation results for the amount of bandwidth consumed by an application. The method can be utilized to limit both the average traffic rate and the maximum burst rate of an application. The disclosed method achieves high efficiency by requiring minimal intervention from a processor and by requiring only additions and subtractions with no multiplications or divisions for its core operations.
