This paper presents a queueing network description of a cellular mobile communications network. These cellular networks an characterised by the call lengths, the fresh call arrival rate, and the handover rates, as well as the capacity restrictions on the number of calls because of limited bandwidth. In the resulting queueing network the routing probabilities depend on the age of the customers. This queueing network is amenable to analysis via known methods. Tn particular, insensitivity results are generalised to also include capacity restrictions under age-dependent routing and to include call holding time distributions of customers moving from one queue to another.
