    Abstract: An apparatus for and method of acquiring an address in a Dynamic Host Configuration Protocol (DHCP) environment in a wireless LAN. The method includes: sensing that a mobile node has moved from a first network to a second network; transmitting a frame requesting association with the second network to an access point managing the second network after sensing that the mobile node has moved from the first network to the second network; and receiving a message containing an address assigned to the mobile node from the access point having received the transmitted frame. Accordingly, the mobile node can promptly acquire an IP address without an additional request.

    Abstract: Disclosed are a fast handover system and a method thereof. The fast handover method can include: allowing a mobile node (MN) to transmit a handover information message to a previous mobile access gateway (PMAG); allowing the PMAG to transmit a fast proxy binding update (FPBU) message to a local mobility anchor (LMA) on the basis of the handover information message received from the MN; allowing the LMA to transmit a handover initiation (HI) message including MN-ID and proxy-care-of address (CoA) of the PMAG to a new MAG (NMAG); transmitting a position update message to the NMAG if the MN is attached to a target BS that is connected to the NMAG; and allowing the NMAG to deliver a buffered packet to the MN.

    Abstract: A handover method and a handover device for a mobile node in a wireless LAN environment are provided. The handover method involves a) scanning beacon signals transmitted from neighboring access routers while a mobile node moves from place to place; b) predicting a new access router (NAR) based on the beacon scanning results; c) obtaining information on the predicted NAR before an L2 trigger of a link layer occurs; and d) carrying out binding update using the information on the predicted NAR when the L2 trigger of the link layer occurs.

    Abstract: An apparatus, method, and medium of automatically configuring a network address are provided. The method of configuring an address of one of a plurality of nodes on a subnet, the method comprising the operations of: obtaining an ID of the subnet from a packet transmitted from a router on the subnet; and configuring an address that none of the nodes on the subnet use as an address of the node among addresses including the obtained subnet ID. Accordingly, an IP address of the node can be automatically and unmistakably (correctly) configured in the current network environment in which performing packet sniffing is difficult.

    Abstract: A method, medium, and apparatus for assuring duplicate address detection. The method includes: determining whether a predetermined packet is related to a duplicate address detection, and if the packet is determined to be related to the duplicate address detection, modifying a source address of the predetermined packet to another predetermined address different from the source address. Proper duplicate address detection can be assured even in an environment where multicast packet filtering is based on a link layer source address that follows the IEEE 802.11 standard.

    Abstract: A data displaying method includes, when a user draws up character messages to be transmitted, the character messages to be transmitted are displayed on one display window. If a window division function is selected, after determining what kind of function is selected, the display window into two display windows, and then the character messages being drawn up are displayed on one of the two divided display windows and data corresponding to the selected function is displayed on the other display window. As a result, the user can carry out another telephone function without losing the character messages being drawn up while drawing up the character messages to be transmitted. Also, the user can carry out smooth communications using character messages.

    Abstract: A method of and a device for communication between a client and server using a flexible address. The method of receiving a flexible address includes: transmitting a request for communication with a server to a proxy, which retains the flexible address of the server; and receiving a response, which includes the flexible address from the server which received the communication request relayed by the proxy. This enables the client to independently communicate with a server which has a flexible private IP address.
