In this paper we present the influence of the connections between GSM users, situated in the same base station (intra-cell connections), on the increase of traffic loss. The utilization of Erlang model in this case gives underestimated loss. We suggest one known queuing model for the more accurate calculation in this case. Several numerical examples prove that traffic loss increases with the increase of intra-cell traffic in total traffic and with the increase of the number of channels in the group. The results are confirmed by the simulation.

PL

W artykule opisano wpływ połączenia miedzy odbiorcami (połączenia intra-cell)stacji GSM na zwiększenie strat w komunikacji. Wykorzystanie do tego celu modelu Erlanga daje przeszacowanie strat. Zamiast tego zaproponowano model kolejkowania.
