Traffic modeling and performance evaluation in GSM/GPRS networks

The sharing of resources between different users and different services is a key concept of radio resources dimensioning in GSM/GPRS networks. In this paper we present dimensioning rules based on traffic evaluation and quality of service level for GSM/GPRS users, focused on two radio resources allocation strategies: CP (Complete Partitioning) and PP( Partial Partitioning). The quality of service is give by the blocking probability according to Erlang-B formula for voice users meanwhile for GPRS users the individual throughput and the blocking probability represent the performance parameters. The preemption probability of voice over data users is also considered.
