This paper presents a study of nonlinear complex behaviour in UMTS networks. Using the fundamentals of chaos theory the paper explores the chaotic nature of the TCP protocol when used in 3G UMTS mobile networks. Furthermore the paper evaluates the impact of nonlinear dynamic behaviour on the UMTS network performance. In order to validate the concept of the investigation, a model of the UMTS network is built using OPNET modeller and simulated under various user traffic loads. Simulation results show the behaviour of the network with increasing traffic load, which ranges from periodically stable to chaotic with a direct impact on network performance.
