Abstract: Congestion control in Signaling System number 7 faces new challenges as mobile com-munication
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 over-load
situation, and respond to it so that the network can maintain high throughput. With the
introduction of a state machine and a memory function for each signaling link it is possible
to predict the completion time of a service session and to detect an emerging congestion. If
the predicted completion time of a service session is too long, the session is annihilated.
This is the foundation of a congestion control mechanism that reacts fast on information
supplied by the network. The congestion control mechanism enables the network to main-tain
a high throughput during overload.
