Abstract:
1. A network system comprising: a first access point including a wired interface module to receive, through a wired network, indication information indicating whether a neighboring second access point supports a protocol to conduct a media independent handover (MIH), and a wireless interface module to transmit the received indication information over a wireless media using a subtype field of a frame control field of a Media Access Control frame indicating that a subnet having the neighboring second access point supports the MIH; and a mobile node to wirelessly receive the indication information corresponding to the neighboring second access point from the first access point via the subtype field of the frame control field of the Media Access Control frame and to conduct a handover according to the received indication information, wherein the mobile node requests the indication information of the neighboring second access point from the first access point and the mobile node has contact with but does not have direct access to the wired second access point due to unresolved information about MIH support, and wherein the indicating whether a neighboring access point supports a protocol to conduct a media independent handover (MIH) is via the management frame having predetermined subtypes.
