Abstract: Disclosed is a high-speed multicast traffic handover method in the PMIPv6. The method provides a multicast LMA and a handover scheme to efficiently support multicasting in the PMIPv6. The method solves the tunneling superposition phenomenon by adding a multicast LMA responsible for managing the multicast traffic. Also, the method provides a way to add a multicast LMAA in an MN-profile to distinguish a general LMA responsible for unicast traffic of a MN in MAG.

Abstract: PURPOSE: A smart TV capable of offering a video call service uses a microphone of a remote controller to recognize a user's voice at a close location, and thereby improves voice recognition and quality of voice call. CONSTITUTION: A remote controller (200) recognizes a user's voice with a microphone (230) and transmits the recognized user' voice. A main body (100) obtains a user's image from a videotelephony service by a camera. If the user's voice is transmitted from the remote controller, the main body transmits the user's voice and the user's image through a set smart TV communications interface to other user's device, receives the image and voice of the other user are received from the other user's device, and displays/replays it.

Abstract: PURPOSE: A PFMIPv6 for the high speed handover of ship communication and an effective interworking method of a WLAN(Wireless Local Area Network) are provided to rapidly execute handover by utilizing a probe request message as a handover trigger and transceiving information which is necessary for handover. CONSTITUTION: An MN(Mobile Node) transmits a probe request message for searching neighbor APs(Access Point), and a pMAG(previous Mobile Access Gateway) executes buffering for preventing the packet loss of the MN. The pMAG broadcasts an MN-ID, HNP(Home Network Prefix), and LMAA information to neighbor MAG(Mobile Access Gateway). A new MAG stores the broadcasted information in a BUL(Binding Update List).

Abstract: Disclosed is a high-speed vertical handover method in a MIH and PFMIPv6 environment. The method enables a corresponding feature via an MIH message without altering a link layer. In other words, a report massage is transmitted to a corresponding terminal′s MIHF, and the MIHF which received the message transmits a MIH_MN_HIrequest which is a network-layer message notifying the initiation of a handover to a PreviousMAG instead of a Handover initiation which is a conventional link-layer message notifying the initiation of a handover.
Abstract translation: 公开了MIH和PFMIPv6环境中的高速垂直切换方法。 该方法通过MIH消息实现相应的特征，而不改变链路层。 换句话说，报告按摩被发送到对应终端的MIHF，并且接收到该消息的MIHF发送MIH_MN_HI请求，MIH_MN_HI请求是通知向先前的MAG发起切换的网络层消息，而不是切换启动 常规的链路层消息通知切换的发起。

Abstract: PURPOSE: A PFMIPv6 based vertical handover method is provided to continuously offer a multimedia service by connecting various APs(Access Point) through a terminal including a multi-wireless interface. CONSTITUTION: When a report message is transmitted by an MIHF(Media Independent Handover Function) of a corresponding terminal, the MIHF transmits a network layer message which notifies the initialization of handover to a previous MAG(Mobile Access Gateway). When the previous MAG receives the layer message, the previous MAG previously transmits information which is the same as an MN-ID(Mobile Node-Identification) and LMAA to a new MAG. After an IP(Internet Protocol) address is set, the new MAG transmits a PBU(Proxy Binding Update) message and receives PBA(Proxy Binding Acknowledgement).
Abstract translation: 目的：提供基于PFMIPv6的垂直切换方法，通过包括多无线接口的终端连接各种AP（接入点）来连续提供多媒体业务。 构成：当通过相应终端的MIHF（媒体独立切换功能）发送报告消息时，MIHF将通知初始化切换的网络层消息发送到先前的MAG（移动接入网关）。 当先前的MAG接收到层消息时，先前的MAG先前将与MN-ID（移动节点识别）和LMAA相同的信息发送到新的MAG。 在设置IP（因特网协议）地址之后，新的MAG发送PBU（代理绑定更新）消息并接收PBA（代理绑定确认）。
