摘要： A handover method of a mobile terminal device in a wireless local area network (WLAN) includes a mobile terminal device and at least two wireless access points (APs) which communicate with the mobile terminal device using particular radio resources. The mobile terminal device communicates with a wireless AP via a first radio resource, and receives signals from wireless APs via a second radio resource. The mobile terminal device arranges and stores the signals received from the wireless APs in a certain order of size. The mobile terminal device determines an AP for the handover by sequentially searching the stored APs when intensity of the signal received via the first radio resource is smaller than a predetermined value.

摘要： A handoff apparatus and method in FMIPv6 for seamless TCP packet transmissions. The handoff method includes steps of intercepting by a previous access router certain TCP packets sent from a correspondent node to a previous temporary address of a mobile node; and creating a TCP ACK by the previous access router in response to the certain TCP packets and sending by the previous access router the created TCP ACK to the correspondent node every time the certain TCP packets are forwarded to a new access router through a bi-directional tunnel. The handoff method has an advantage in that the packet transmission rate can be secured at the same level as the mobile node stays still during the performance of the handoff of the mobile node since the previous access router instead of the mobile node creates and sends the TCP ACK to the correspondent node during the performance of the handoff of the mobile node.

摘要： A control method for a mobile terminal which connects to a router linked to an external network through at least one interface, including receiving a router advertisement message from the router through a first interface, determining whether prefix information of the received router advertisement message is identical with prefix information of a preset internet protocol (IP) configuration reuse group including the first interface, and generating an IP configuration of the first interface when the two prefix information are identical. Accordingly, at the time of a vertical handover, continuity of the A/V session can be maintained without having to use mobile IP technology.
