Abstract
(English)
This paper deals with congestion analysis of a GPRS network composed of N cells partially overlapping. In particular, we consider that one of the 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 others. In order to efficiently solve this complex scenario, we introduce a resolution technique that overcomes the state space explosion problem by decomposing the overall model in a set of more simple and easier to solve models.
