摘要：
To provide a method and network system, wherein the proper VPI values are allocated, after the user devices are connected with the network device. A user device transmits a first specific ATM cell, while a network device receives the first specific ATM cell and transmits toward the user device a second specific ATM cell which carries a proper VPI value in the information field of ATM cell. The proper VPI value in the second specific ATM cell is memorized and used by the user device for its own VPI value for communication.
