Analysis of a two-layer cellular mobile communication system

Teletraffic aspects of hierarchical cellular systems with a focus on a reversible system are presented. An analytical model based on product forms is proposed. For the same QoS objective, carried traffic in the reversible system is superior to the non reversible scheme. The impact of the resource partition between layers is studied in a hierarchical network with independent layers. The mean number of handovers per call and the base station density are used to optimize the partition.
