Resources sharing between different users and different services is a key concept of radio resources dimensioning in GSM/GPRS networks. This paper addresses the dimensioning problem of GSM/GPRS networks based on performance parameters focusing on the influence of different traffic models used. For voice traffic the Erlang-B model was considered in both cases meanwhile for data traffic we have adopted the Erlang-B model and the Engset model. Two radio resources allocation strategies: CP (Complete Partitioning) and PP( Partial Partitioning) were also considered. Based on performance parameters (blocking probability, preemption probability of voice traffic over data traffic, average total throughput and average throughput per user) we have compared the two models in order to find the adequate model to use for dimensioning purposes.
