Mobile data communication is today evolving from circuit switched
to packet switched connections to be able to bring forward the Mobile
Internet. Useful services in the mobile world are corporate access,
E-mail and WAP/WWW browsing. To be able to predict how packet based
services performs over the not yet released EGPRS radio network traffic
models is used. These are combined with system simulators that describe
the characteristics of the radio network.
In this work a WAP traffic model has been developed with the purpose
to modulate the WAP user behaviour in a radio cellular network. The
resulting traffic model is based on WAP traffic studies in real networks
and experience from other traffic models.
The traffic model was implemented in a radio network simulator in
order to evaluate the WAP performance. Results for WAP over EGPRS
and GPRS was studied and compared with earlier results for the WWW
service both on user and on system level. Since most traffic in a
mobile network is assumed to be access to services only downlink traffic
was considered in this report.
