Abstract
A multi-service traffic model is briefly presented, and
its validation is achieved by using event-based simulation results
which consider the burstiness of traffic. A simulator was
produced to extract conclusions about blocking and handover
failure probabilities in a multi-service bursty traffic context.
Simulations, were performed for different cases, from single- to
multi-service situations, and from absence to presence of
mobility. Besides quality of service results in the air interface,
including blocking and handover failure probabilities, the
simulator allows for extracting conclusions about the validation
of the Bernoulli-Poisson-Pascal model for the computation of the
on/off blocking probability, the ratio between the number of call
rejected at the beginning of an on period and the total number of
bursts generated during a session. In the single-service case, the
theoretical and the experimental values of on/off blocking
probability are close to each other, and there is an almost perfect
concordance between theoretical and simulation values when the
average sojourn time in cells is equal to the average holding time.
In the multi-service case, the behaviour is not exactly the same
but a coherent behaviour is achieved for an average traffic per
user up to 0.10 Erl.
