Abstract: PURPOSE: An interworking method and apparatus between an IPv4(Internet Protocol version4) network and an IPv6(Internet Protocol version6) network are provided to enhance processing rate of a packet and performance by suitably disposing an NAT(Network Address Translation)-PT(Protocol Translation) performing unit according to the scale of a network. CONSTITUTION: An IPv6 packet is received(S710), and a current packet processing state of an NAT-PT performing unit is received(S720). If the current packet processing state is not smaller than a pre-set threshold value(S730), information that the IPv6 packet cannot be processed anymore is transferred to an IPv6 node(S740). If the current packet processing state is smaller than the threshold value(S730), an IPv4 address mapped to the address of the IPv6 node is read from an IPv4 address pool(S750). A header of the received IPv6 packet is converted into an IPv4 header(S760) and the packet received from the IPv6 node is sent to an IPv4 node(S770).

Abstract: PURPOSE: A handover method in a wireless LAN environment and a handover apparatus of a mobile node are provided to reduce handover latency by performing an operation of fetching information of a new access router to be connected before L2 trigger. CONSTITUTION: A beacon scan unit(510) scans beacon signals transmitted from access routers around it. An NAR(New Access Router) predicting unit(520) predicts an NAR by using strength of scanned beacon signals. A pre-processor(530) processes to previously obtain prefix information of the predicted NAR. An NAR information storing unit(540) stores the previously obtained NAR information. A binding update processor(550) generates a care-of-address by using the NAR prefix information and transmits a binding update message to a previous access router by using the generated care-of-address.

Abstract: PURPOSE: A mobile phone and a data display method are provided to display data according to a select input type on a display window as divided according to selection of a window dividing function while a user is writing a character message. CONSTITUTION: When a user selects a character message function to transmit a character message, a controller displays a transmission character message created by the user on one input display window(310). The controller judges whether a reception character message and a call setup request have been received from an external wireless communication network or whether the user has selected a window dividing function, and if the user selects the window dividing function, the controller discriminates a selection input type(320). The controller divides the display window into two section, and displays the transmission character message being created in one section and a data corresponding to a selection input type in another section of the display window.
