Method of overload control for the central of a telecommunication system and arrangement for implementing the method.

摘要

The central processor of a telecommunication system is designed for performing many as well as a great variety of tasks. Owing to the more or less accidental character of the demand for processor time (long) waiting times can arise or even overload can occur. The method according to the invention has for its object to avoid this or to control this. As a measure for processor load it is suggested to take the number of calls in build-up phase and the queue length (the number of tasks waiting to be processed by the processor). Based on the value of the maximum number of tasks-in-process determined again and again it is detected whether a new task is acceptable in view of the tasks still waiting to be performed.
