Abstract: Congestion control in Signaling System #7 faces new challenges as mobile
communication systems and Intelligent Networks grow rapidly. New services
change traffic patterns, add to signalling network load, and raise demands on
shorter service completion times. To handle new demands, the congestion control
mechanisms must foresee an overload situation, and respond to it so that the net-work
can maintain high probability for successful service completion. By measur-ing
the time consumption for the initial Message Signalling Units of a service
session it is possible to predict the duration of the service session and to detect an
emerging congestion. If the predicted duration of the service session is too long,
the service session is annihilated. This is the foundation of a congestion control
mechanism that reacts fast and on information supplied by the congested part of
the network. The congestion control mechanism increases the ratio of successfully
completed services during congestion by several hundred percent.
