Packet Data Service over GSM Networks: proposal and Performance Evaluation Attempt

There is a rapidly growing demand for low-cost packet data services in GSM networks. Therefore, the ETSI is considering the possible introduction of a general packet radio service (GPRS) in GSM. We propose an enhancement of a GPRS proposal which improves the utilization of the radio resource. In particular, we consider a random access technique, that is very close to the PRMA, and allows mobile stations to share all data traffic channels available in the cell. In this context, the performance of typical data applications, which require short messages, are evaluated by simulations. The results obtained confirm the validity of this proposal even if more accurate investigations are needed for its complete definition
