摘要： An open access node receives a dynamic IP address corresponding to a terminal that requests a connection from a specific server, and provides the dynamic IP address to the terminal. Next, the open access node receives a service that is requested by a user from the terminal that is connected using the dynamic IP address, and stores a MAC address of the terminal and a service in a database. When the terminal again requests a connection, the open access node identifies a service that is requested by a user of the terminal based on the MAC address of the terminal.
