Abstract
All service control nodes, for example SCPs, HLRs, and MSCs, are constructed as a server system

with one or more servers that process incoming requests. Since service control nodes are sensitive to

overload, admission control mechanisms are often implemented. In this paper, we model and analyse

admission control mechanisms for server systems with control theoretic methods. We develop a nonlinear

stochastic control theoretic model of a GI/G/1-system. Further, we show that this model can be

used to design admission control mechanisms that behave well in the “real” system, that is the queuing

system. We develop two types of controllers for the system, one PI-controller and one... (More)

both commonly used in automatic control. Also, we discuss some of the limitations of previous work in

this area, in which only deterministic and linear models have been used. (Less)
