Combined techniques for channel allocation algorithms in mobile radio systems

Global assignment techniques, comprising the various forms of the dynamic channel allocation algorithms, and local assignment techniques, characterised by the algorithms taking advantage of the traffic available at the overlapping service areas, are combined into a common algorithm for mobile radio applications. The performance analysis is carried out by means of the Monte Carlo simulation having a real cellular network as the system under study. The results show a remarkable traffic performance, substantially better than that attained by the individual techniques. An increase in the complexity due to the combination is certainly expected, but, because the local techniques are reasonably simple to implement, it is believed that the overall complexity is mostly dictated by that inherent to the global technique.
