Connection Admission Control Issues for a CDMA Return Link in the Aeronautical Broadband Communication System

Inhalt:
One of the hot topics in the communication world is to realize a network able to offer a combination of services complying with different requirements in every place of the world, thus achieving the concept of "entertainment everywhere". In such a context a key role is played by aeronautical world that seems to be one of the last remaining islands in which broadband communications are not available. The present paper aims at studying resource management for a CDMA-based return link via satellite to provide passengers with new generation services. We focus on the connection admission control problem for QoS guarantees, analyzing in particular, the effective bandwidth concept over CDMA discussing its applicability to a multi-service packet switched network. Two admission control algorithms are then derived, based on the effective bandwidth concept for the circuit switched-like services and on a moving average window and linear predictor model for packet switched services. Finally, the performance over aeronautical broadband communication system is evaluated.
