ABSTRACT:
A method and apparatus for providing a gateway for IPv6 packet transmission in a WLAN system are provided, in which a gateway takes over a TCP/IP protocol stack from a legacy 6LoWPAN node for providing a gateway for IPv6 packet transmission in a WLAN system. One or more service request messages for data communications are received from a plurality of 6LoWPAN nodes, and a virtual interface is generated for allocating IPv6 addresses to the 6LoWPAN nodes by adding a predetermined IPv6 address prefix to addresses of the 6LoWPAN nodes set in the service request messages. A socket adaptation layer is interfaced for receiving the IPv6 addresses from the virtual interface and transmitting data packets to the 6LoWPAN nodes, and when data packets are transmitted and received to and from the 6LoWPAN nodes, an on-going file is controlled and managed, and the data packets are routed.
