    摘要： A mobile network is disclosed in which there exists a Mobile Node (MN), the MN is managed by a first Access Router (AR), and there exists a second AR with a subnet different from the first AR. A method is provided for the MN performing a fast handoff from the first AR to the second AR, which includes receiving a Routing Advertisement (RA) message of the second AR from the first AR, generating an IP address to be used in the second AR using the RA message of the second AR if the MN recognizes that it should perform a handoff from the first AR to the second AR, performing a trigger for using the generated IP address if the movement to the second AR is completed, and transmitting/receiving a Correspondent Node (CN) and data using the IP address.

    摘要： A method and apparatus for supporting a multicast/broadcast in a wireless communication system are provided. A multicast/broadcast method receives an Internet Protocol (IP) packet from an upper layer, determines whether a multicast destination address or a broadcast destination address is contained in the received IP packet, and transmits a packet in which a connection identifier (CID) for the multicast or the broadcast is selectively attached to the received IP packet according to a result of the determination. Also, the multicast/broadcast method may receive an IP packet from a mobile station, determine whether a first CID for the multicast or the broadcast is contained in the received IP packet, and transmit a packet in which the first CID of the received IP packet is selectively replaced with a second CID according to a result of the determination.

    摘要： A network emulation device and method in a terminal of an IEEE 802.16 communication system supporting IPv6 communications based on a Neighbor Discovery (ND) protocol are provided. The terminal includes an IPv6 module for performing an ND mechanism to search for a neighbor terminal or a router, a MAC module for communicating based on the IEE 802.16 standard, and a network emulation module provided between the IPv6 module and the MAC module for analyzing a ND message received from the IPv6 module and discarding the ND message or generating a response message for the ND message according to the message type. The network emulation module converts a broadcast ND message to a unicast message and provides the unicast message to a corresponding network device if network information needed to internally generate the response message is not collected.
