Abstract
(English)
This paper deals with congestion analysis of a simple GPRS network composed by two cells partially overlapping. In particular, we consider that one of the two cells is affected by an outage and we analyze the effectiveness of applying a class of congestion treatment techniques that ultimately results in a switching of users from the congested cell to the other one. For this purpose, we introduce a modelling technique to support a proper calibration of the parameters involved in a reconfiguration action, in order to successfully treat the congestion phenomenon. The effectiveness of a reconfiguration action is evaluated in terms of indicators that represent the Quality of Service (QoS) perceived by the users in the congested and adjacent cells.
