摘要： A method is related to support a QoS service at a handed over network in heterogeneous networks. A serving network requests the mobile terminal to offer demand QoS information, when there is a need of handover. The mobile terminal sends a response message containing the demand QoS information to the serving network, and each candidate network maps the demand QoS information to its network resources to judge whether or not to support the QoS service. And the serving network determines one of the candidate networks that can support the QoS service depending on the judgment of the candidate networks, and provides information on the determined candidate network to the mobile terminal such that the mobile terminal is handed over to the determined candidate network.

摘要： A vertical handover method between heterogeneous wireless networks is provided to offer mobility with minimum packet loss until an MN(Mobile Node) completes a BU(Binding Update) process while moving to a new network from a previous network in an MIH(Media Independent Handover)-based network environment where a WiBro(Wireless Broadband Internet) network and a WLAN(Wireless LAN) exist together. Based on the information received through an MIH message, an MN prepares for handover to a WiBro network. In this case, the MN activates a WiBro interface(S304). Then the MN sends an "MIH_handover_notify" message to an old AR(Access Router)(S306). Receiving the MIH_handover_notify message, the old AR sends an "MIH_handover_notify_request" message to a new AR(S308). Receiving the MIH_handover_notify_request message, the new AR starts buffering for the data delivered to the MN, and creates a tunnel(S310). The MN transmits a router solicitation message to the new AR through an AP(Access Point)(S312), and receives a router advertisement from the new AR(S314). Afterwards, the MN transmits a BU message to an HA(Home Agent)(S316), and receives a response message from the HA(S318). At this moment, the HA sends an MIH_FORWARD message to the old AR(S320). Receiving the MIH_FORWARD message, the old AR delivers packets, which was buffered before handover, to the new AR through the tunnel(S322).
摘要翻译：提供异构无线网络之间的垂直切换方法，以提供最小分组丢失的移动性，直到MN（移动节点）在MIH（媒体独立切换）中从先前网络移动到新网络之前完成BU（绑定更新）过程，基于WiBro（无线宽带因特网）网络和WLAN（无线LAN））的网络环境。基于通过MIH消息接收的信息，MN准备切换到WiBro网络。在这种情况下，MN激活WiBro接口（S304）。然后，MN向旧的AR（接入路由器）发送“MIH_handover_notify”消息（S306）。接收到MIH_handover_notify消息，旧的AR向新的AR发送“MIH_handover_notify_request”消息（S308）。接收到MIH_handover_notify_request消息，新的AR开始缓冲发送给MN的数据，并创建隧道（S310）。 MN通过AP（接入点）向新的AR发送路由器请求消息（S312），并从新的AR接收路由器通告（S314）。之后，MN向HA（归属代理）发送BU消息（S316），并从HA接收响应消息（S318）。此时，HA向旧的AR发送MIH_FORWARD消息（S320）。接收到MIH_FORWARD消息，旧的AR将通过隧道将缓冲的数据包（S322）传送到新的AR。

摘要： 아날로그 방송과 디지털 방송의 음향신호 출력의 자동 보정장치 및 그 보정방법이 개시된다. 본 발명에 따르면, 동일한 내용의 방송을 디지털 방송채널과 아날로그 방송채널로 동시에 방송하는 병행방송을 수신하는 경우에, 아날로그 음향신호와 디지털 음향신호의 변조도의 차이 배수만큼 디지털 음향신호의 출력을 더 증폭한다. 그럼으로써, 아날로그 음향신호의 과변조에 따른 디지털 음향신호와 아날로그 음향신호의 출력이 달라지는 것을 자동보정할 수 있다. 본 발명에 의하여, 채널을 변경할 때마다 음향신호의 출력을 조정할 필요가 없게되어, 사용자의 편의를 도모할 수 있다.

摘要： PURPOSE: A method for supplying mobility of an MN(Mobile Node) by using a regional anchor point in an advanced Internet network and a system therefor are provided to use an access router only located within a certain range as an anchor point, and to use a CoA(Care-of Address) of an existing access router as a regional CoA, thereby preventing a tunnel from getting larger and removing an overhead. CONSTITUTION: An MN decides whether the MN moves to an external network from a home network(110). If so, the MN obtains a CoA from a current access router(120). The MN decides whether an RAP(Regional Anchor Point) function exists in the access router(130). If so, the MN sets the access router to an fRAP(140). If the RAP function does not exist in the access router, the MN sets the fRAP to "Null"(141). The MN requests a home agent and CNs(Corresponding Nodes) to bind-update the current CoA and a self home address, and completes an RAP setting process(150).

摘要： PURPOSE: A digital video system and a method of controlling the digital video system are provided to control a video signal to display the video signal in accordance with a radio communication environment. CONSTITUTION: A digital video system includes an image receiver(200) and an image transmitter(100). The image receiver analyzes a video signal packet received through the first transmission/reception unit to check a transmission error rate, and transmits a grade control request signal that requests a resolution grade of the video signal to be increased or decreased through the first transmission/reception unit to the outside according to the checked transmission error rate and a resolution grade of a currently received video signal. The image transmitter converts a video signal to be transmitted to the image receiver to a video signal corresponding to the grade control request signal to transmit the signal to the second transmission/reception unit corresponding to the first transmission/reception unit.
