- E-UMTS Services and Applications CharacterisationPublication . Ferreira, Jaime; Velez, Fernando JoséDifferent points of view are compared for the classification of Enhanced UMTS (E-UMTS) mixture of applications, namely ITU-T I.211, UMTS Forum and 3GPP ones. A set of characterisation parameters (e.g., data rate, tolerance to delay and error, and session duration) is described, and a first assignment of parameter values for these services is proposed. An overview of E-UMTS deployment scenarios and supported services is then presented, based on the views of nowadays-relevant players. The influence of mobility in E-UMTS is discussed, and mobility models and scenarios are given. Deployment and mobility scenarios include expected population density, mobility characteristics, and usage of service mix, for each environment. A number of nearly thirty applications are considered. However, a reduced set of applications is needed for simulations purposes, and scenarios were defined with a selection of the most relevant applications. Finally, E-UMTS traffic generation and activity models, based on population and service penetration values, were described and characterised. ON/OFF states were characterised by appropriate statistical distributions and parameters.
