  • Rare probability connection call registration method using incomplete call causation message for asynchronous transfer mode switching system
    Patent number: 5862204
    Abstract: An improved rare probability connection call registration method using an incomplete call causation message for an asynchronous transfer mode switching system, which includes the steps of receiving a candidate code from an operator and classifying a normal call and an abnormal call with respect to each call when a call cause message is received, increasing the number of completed calls when the received call is normally completed, and judging whether an incomplete call occurred due to the lack of a switching resource or the busy state of the subscriber at a destination in the case of the abnormal call, terminating the call when the cause of the abnormal call is due to another cause except for the lack of the switching resource, or the on-busy of the subscriber, increasing the number of the incomplete calls when the call is incompletely terminated due to the lack of the switching resource or the on-busy of the subscriber, and checking the call completion ratio, and terminating the call when the call completion
