Asymptotic behavior of a GPRS/EDGE network with several cells controlled by a global capacity limit
Résumé
This paper is a contribution to the generic problem of having simple and accurate models to dimension radio cells with data traffic on a GPRS or EDGE network. It addresses the issue of capacity limitation in a given cell due to coupling with other cells because of a central equipment or transmission link of limited capacity. A mobile can’t access the cell although it is alone, because the capacity limit is reached due to traffic on other cells. Our purpose is to extend our previously published Erlang-like law for data traffic to the constrained multiple-cell system and to derive asymptotic developments for all the average performance parameters that are necessary for the dimensioning of the multiple-cell system.
