Resumo(s)
Different 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.
