Overload Control for the Wireless Intelligent Network

Abstract

Wireless intelligent network (WIN) is a network in the mobile environment that supports the use of intelligent network capabilities which is mainly made up of a service control point (SCP) and some mobile switching centers (MSCs). When there are too more incoming services to SCP and MSCs in the WIN simultaneously than they can handle will cause the SCP or MSCs overload and degrades the performance of the WIN. To resolve this problem, we introduce a queue model, design an overload control model and put forward a two-level overload control algorithm for the WIN. The results of our analysis and experiments show that our overload control algorithm is effective.
