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.

Provided is a method of generating and managing a connection identifier (CID) for supporting an IPv6 multicast in a wireless network based on IEEE 802.16 and a network interface using the method. Further provided is a network interface included in a node of IPv6-based wireless network, the network interface includes a MAC driver for storing at least one multicast CID and a MAC address of the node which is mapped in the at least one multicast CID, and a control unit for receiving a multicast message which is transmitted from a base station, and transferring the multicast message to an IP layer, when the multicast message includes the multicast CID which is stored in the MAC driver.

A mobile station and method for neighbor discovery are provided. The mobile station comprises a mapping table storing a connection identifier (CID) prefix and a neighbor identifier, a controller generating a CID with respect to a message that will be transmitted by referring to the mapping table, and a message transmitter transmitting, by using the CID, the message to a base station connected to the mobile station.

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.

An apparatus for a fast reactive handover in an Internet Protocol version 6 (IPv6) mobile system is provided, in which a message receiver receives a new connection notification message from a point of attachment when the point of attachment makes a new connection with a mobile unit, and a message transmitter sends a router advertisement (RA) message to the mobile unit in response to receiving the new connection notification message.

摘要:
A method of configuring and registering an Internet Protocol (IPv6) address in a wireless mobile communication system having a connection-oriented radio link is provided. In an IP configuration method without Duplicate Address Detection (DAD), a Mobile Station (MS) is allocated a unique Connection Identifier (CID) specific to the MS from a serving Base Station (BS), and the MS and BS configure the IPv6 address independently using a known network prefix, a Medium Access Control (MAC) address of the MS, and the allocated CID. The BS registers the configured IPv6 address to a HA on behalf of MS.
