Abstract
An efficient utilisation of the radio resources in mobile communications is of a great importance. If the capacity is split into many independent small groups, then for a given blocking probability the utilization becomes low. In this paper we describe the basic principles and strategies for obtaining maximum utilisation as given by Erlang’s B-formula. The models described are analytical models and generalisations of the Erlang-B formula, including general arrival processes and multi-rate (multi-media) traffic for second and third generation systems. A transformation from cell-based network to direct routing network model is used to carry out the calculations. By numerical examples we study the statistical multiplexing advantages of cell breathing, overlapping cells and hierarchical cell structures.
