"Analytical Comparison of Different GPRS Introduction Strategies"
to appear in MSWim 2000 Workshop, Boston, August, 11th, 2000
The ongoing introduction of GPRS services in existing GSM networks by mobile
network providers raises the ques-tion of the best strategy to partition
the available cell capacity. The paper describes three different strategies
complete partitioning, partial sharing and complete sharing.
An analytical call/burst level model of one cell of a homogeneous multiservice
GSM/GPRS network is used to investigate these strategies with respect to
mportant performance measures like new and handover blocking probabilities,
system utilization and mean data rates of the services.
Numerical results show, that the complete sharing strategy in connection with
the proposed admission policy achieves a high system utilization while even
for low priority data connections some minimum quality of service
