1. An IPv6 neighbor discovery support method by a base station in a wireless communication system where all attached subscriber stations share a common network prefix, the method comprising:

  • receiving a neighbor solicitation (NS) message that is transmitted from a Request SS to resolve a MAC address of a Target SS;

    determining whether or not a base station is a Target BS that provides a service to the Target SS with reference to an Identification Cache Table (ICT) (i.e., a table including subscriber stations'"'"' MAC addresses, and subscriber stations'"'"' IP addresses and their valid flag information);

    causing the Target BS instead of the Target SS to respond to the NS message with a neighbor advertisement (NA) message, when the base station is determined as the Target BS;

    causing the Request BS to receive the NA message from the Target BS; and

    causing the Request BS to transmit the NA message to the Request SS.
