An efficient utilisation of the radio resources in mobile communications is of a great importance. In general a high degree of sharing is efficient, but requires service protection mechanisms to guarantee the Quality of Service for all customers. We study the effect of cell breathing and overlapping along with hierarchical cell structures. We show that by call packing we obtain a high utilisation. The transformation from cell-based network to direct routing network model is used to carry out calculations. The models in discussion are a generalisation of the Erlang-B formula, including general arrival processes and multi-rate (multi-media) traffic for second and third generation systems.
