IP traffic transmission over the general packet radio services

One IP terminal can occupy a multiple number of slots within time frames in the GPRS networks. A limited number of radio resources (slots) are allocated in a base station for such IP terminals. If one IP terminal can occupy only one slot discontinuously in a time frame, for a real time packet transmission, the number of accepted calls is obtained by dividing the number of radio resources during that time by the maximum allowed number of IP calls. The real time IP traffic flow over the GSM-GPRS network is discussed in [J.H. Sarker and S.J. Halme, 2002]. An analysis for the non-real time bursty IP packet transmission over the GPRS air interface that measures the channel efficiency and the probability that a packet is forced for queuing and the header/payload ratio are executed in this paper. Results show that the channel efficiency as well as the probability that a packet is forced for queuing increases with increasing call intensity, maximum number of admitted IP calls and the burstiness factor. The channel utilization decreases with the increase of header/payload ratio.
