Patent ID: 8005080

Claim:
An address configuration method in which a router configures an Internet Protocol (IP) address of a terminal, the method comprising: extracting a media access control (MAC) address from a field of a MAC management message requesting an initial registration received from the terminal; generating an interface address of the terminal by using the MAC address; generating the IP address of the terminal by attaching a network prefix of the router to the interface address of the terminal; and transmitting the generated IP address to the terminal in a field of another MAC management message, wherein the generated IP address is transmitted to the terminal prior to the terminal performing an auto-configuration of its IP address, and wherein the transmitted IP address is used by the terminal for performing auto-configuration of its IP address, and wherein the other MAC management message is a provisioned dynamic service addition request (DSA_REQ) message and the field of the other MAC management message in which the generated IP address is transmitted to the terminal is a convergence sublayer (CS) parameter encoding rule_packet classification rule_IP masked destination address field among fields of the provisioned DSA_REQ message.
