Abstract:
The introduction of GPRS leads to new challenges for the
dimensioning of mobile radio cells. While with circuit switched
connections only the number of frequencies in a cell was
determined by the Erlang formula, with GPRS it becomes more
complicated. Additional to the blocking probability of a voice
user the performance of a GPRS user is a planning criterion. This
performance depends on different factors, the voice traffic, the
data user profile, and the GPRS implementation. The objective of
the cooperation is to define a stochastic data user model which is
used in a simulation of a GPRS cell to derive the quality of
service of the user for different traffic profiles and cell
configurations.
