Abstract
A traffic management system with overload control functions which deals with traffic congestion happened in a particular coverage area as part of a telecommunications network system. The traffic management system comprises two main units: an overload controller and a call restriction processor. The overload controller identifies the coverage area in a high-traffic condition and activates the call restriction processor deployed in the identified area. Under the control of the overload controller, the call restriction processor regulates the acceptance of calls from subscribers within the area. To provide such overload control functions, the overload controller comprises the following processors. An originating call analysis processor analyzes each originating call to locate the coverage area where the call setup request was initiated. A call-restricted area search processor determines whether to designate the originating coverage area as a call-restricted coverage area which is subject to call restriction. A restriction control message processor sends a restriction control message that specifies an operation to be executed by the call restriction processor.
