Resumo(s)
Multi-service traffic engineering will be a key aspect in cellular planning for Mobile Broadband Systems, the feasibility of the aggregate traffic model being crucial. An MMPP model is proposed for the modelling of the
superimposition of data and video IPP sources. Given the correspondence between applications and their bearer service components, an algorithm for the Bernoulli case of the Bernoulli-Poisson-Pascal model is used to compute the blocking probability. The supported number of users is higher in scenarios with a lower maximum load per user. In a cell with 384 channels of 384 kb/s, it varies from 20 to 26 users/cell in urban scenarios, while with 288 channels/cell, although the number of channels is only 25 % lower, the supported number of users decreases 50 %. High terminal mobility strongly degrades the performance in the roads scenario.
