Accounting system and method for ATM network and ATM network

摘要

An accounting system for an ATM network includes a first unit (23; 130) for detecting a VCI (Virtual Channel Identifier) in an ATM cell and information type data contained in the ATM cell. The information type data indicates the type of information contained in the ATM cell. A second unit (24; 140) outputs an accounting coefficient related to the information type data detected by the first unit. A third unit (25; 150) generates a cell arrival signal in response to arrival of each ATM cell having an identical VCI value and generates accounting data by using the accounting coefficient and the cell arrival signal.
