Abstract:
1. A method for interworking with a Broadband Wireless Access (BWA) network in a Wireless Local Area Network (WLAN) terminal, the method comprising: connecting, by a relay station, a Wireless Local Area Network (WLAN) terminal to a Broadband Wireless Access (BWA) network using an initialization process; performing, by the relay station, a user authentication process with the Wireless Local Area Network (WLAN) terminal in compliance with a Wireless Local Area Network (WLAN) protocol; performing, by the relay station, a user authentication process with a Broadband Wireless Access (BWA) network Access Control Router (ACR) in compliance with a Broadband Wireless Access (BWA) network protocol; sending, by the Wireless Local Area Network (WLAN) terminal, an Internet Protocol (IP) address allocation request to the relay station and relaying, by the relay station, the Internet Protocol (IP) address allocation request to a Broadband Wireless Access (BWA) network Radio Access Station (RAS); sending, by the Broadband Wireless Access (BWA) network Radio Access Station (RAS), a notification of a Connection IDentification (CID) corresponding to a Quality of Service (QoS) level of the Wireless Local Area Network (WLAN) terminal and an Internet Protocol (IP) address allocated to the Wireless Local Area Network (WLAN) terminal, to the relay station; and mapping and storing, by the relay station, the Connection IDentification (CID) and the Internet Protocol (IP) address of the Wireless Local Area Network (WLAN) terminal, and forwarding the Connection IDentification (CID) to the Wireless Local Area Network (WLAN) terminal, wherein performing, by the relay station, the user authentication process with the Broadband Wireless Access (BWA) network Access Control Router (ACR) comprises receiving a public key created using a Media Access Control (MAC) address of the Wireless Local Area Network (WLAN) terminal and relaying the public key to the Wireless Local Area Network (WLAN) terminal after the Broadband Wireless Access (BWA) network Access Control Router (ACR) performs the user authentication process.
