- Enhanced UMTS Deployment and Mobility ScenariosPublication . Ferreira, Jaime; Gomes, Álvaro; Velez, Fernando JoséAn overview of Enhanced UMTS (E-UMTS) deployment scenarios and supported services is presented, based on the views of nowadays-relevant players. The influence of mobility in E-UMTS is discussed and a set of mobility models is given. Then, a set of scenarios is described, that put together the most important components of E-UMTS deployment situations. These include expected population density, mobility characteristics, and expected usage of service mix, for each environment. A number of nearly thirty applications, divided into in five groups (Sound, High Interactive Multimedia, Narrowband, Wideband, Broadband), is considered.
- Parameters for Tele-traffic Characterisation in Enhanced UMTSPublication . Clemente, Marco A.; Velez, Fernando JoséA description of Enhanced UMTS (E-UMTS) characterisation parameters is presented, and a first assignment of parameter values for these services is proposed. Different points of view are compared for the classification of the mixture of applications, namely ITU-T I.211, UMTS Forum and 3GPP ones. Characterisation parameters includes among others data rate, tolerance to delay and error, busy hour call attempt and session duration.
