ABSTRACT:
A billing data is relieved by a relief method of billing data when a failure occurs on SVC (Switched Virtual Connection) calls which subscribers connect and disconnect. The relief method of billing data on an asynchronous transfer mode switching system includes an asynchronous transfer mode switch, a terminator provided on an input side of said asynchronous transfer mode switch for counting the number of cells sent from subscribers or other switching system, and a call controller for controlling paths on said asynchronous transfer mode switch, collecting a count value of the numbers of cells on said terminator, and creating billing data according to the count value of the collected cell number and call control data, wherein only the count value of the number of the cells counted on said terminator is removed from the values to be initialized on initialization caused by a failure.
