摘要： There are provided a quality of service (QoS)-providing system and a method for providing quality of service for mobile nodes (111) in the QoS-providing system. Under a network environment running a host-based network layer mobility protocol based on tunneling mechanism, the QoS-providing system may be useful to allow effective mobility supports by distributing binding information to the distributed nodes, in order to provide session-based quality of service for tunneled packets between the mobile nodes (111) on the acces (120a-120n) nodes and distribute traffic load concentrated on the central mobility control platform (130) as well. Also, the QoS-providing system according to one exemplary embodiment of the present invention may be useful to provide the function of hiding locations of mobile nodes (111) since a care-of address of the mobile node (111) is not transferred to a correspondent node (112) and to automatically perform a route optimization procedure even when the mobile node does not directly perform a route optimization procedure.

摘要翻译：提供了一种服务质量（QoS）提供系统和一种为QoS提供系统中的移动节点（111）提供服务质量的方法。在运行基于隧道机制的基于主机的网络层移动性协议的网络环境下，QoS提供系统可能有助于通过向分布式节点分发绑定信息来实现有效的移动性支持，以便提供基于会话的服务质量对于接入点（120a-120n）节点上的移动节点（111）之间的隧道分组，并且分配集中在中央移动性控制平台（130）上的业务负载。此外，根据本发明的一个示例性实施例的QoS提供系统对于提供隐藏移动节点（111）的位置的功能可能是有用的，因为移动节点（111）的转交地址不被传送到通信节点（112），并且即使当移动节点不直接执行路由优化过程时也自动执行路由优化过程。提供了一种服务质量（QoS）提供系统和一种为QoS提供系统中的移动节点提供服务质量的方法。在运行基于隧道机制的基于主机的网络层移动性协议的网络环境下，QoS提供系统可能有助于通过向分布式节点分发绑定信息来实现有效的移动性支持，以便提供基于会话的服务质量对于接入节点上的移动节点之间的隧道分组，并且分配集中在中央移动性控制平台上的业务负载。此外，根据本发明的一个示例性实施例的QoS提供系统对于提供隐藏移动节点的位置的功能可能是有用的，因为移动节点的转交地址不被传送到通信节点并且自动执行即使当移动节点不直接执行路由优化过程时，路由优化过程也是如此。

摘要： A tunneling-based mobility support method and apparatus is provided which supports a mobility of a mobile node in a heterogeneous network regardless of IP versions (IPv4/IPv6). The mobility support apparatus includes a load balancer, a plurality of mobility support servers, and a plurality of end routers each being TCP connected to each of the mobility support servers. When receiving a tunnel establishment request message from the mobile node, the load balancer selects one mobility supports server from a plurality of mobility support servers to control a mobility service for the mobile node. The selected mobility support server selects a plurality of tunnel end addresses of one end router from the plurality of end routers to establish an IP tunnel with the mobile node according to a predetermined criterion, forwards the tunnel establishment request message to the end router, and sends the mobile node a tunnel establishment response message including the tunnel end address of the selected end router.

摘要： A system and method of controlling transmission of adaptive media over handover performed between heterogeneous networks are disclosed. When a mobile terminal moves, it detects the necessity of handover between the heterogeneous networks, determines a target network to which it may perform handover, and transmits handover information to an adaptive media server that controls a transmission rate of adaptive media to previously inform about the handover. Then, the adaptive media adjusts a transmission rate of the adaptive media by using the received handover information, and when the mobile terminal performs handover to the target network, it can receive the adaptive media from the adaptive media server. Accordingly, when the mobile terminal using a real time multimedia service in a wireline/wireless environment in which various accessing techniques are integrated performs handover between heterogeneous networks, a change in quality of experience (QoE) sensed by subscribers due to the handover can be reduced.
摘要翻译：公开了一种在异构网络之间执行的跨越切换的自适应媒体的传输控制系统和方法。当移动终端移动时，它检测异构网络之间切换的必要性，确定其可以执行切换的目标网络，并将切换信息发送到控制自适应媒体的传输速率的自适应媒体服务器，以便先前通知交出。然后，自适应媒体通过使用接收到的切换信息来调整自适应媒体的传输速率，并且当移动终端执行到目标网络的切换时，它可以从自适应媒体服务器接收自适应媒体。因此，当在各种接入技术集成的有线/无线环境中使用实时多媒体业务的移动终端执行异构网络之间的切换时，可以减少由于切换而由用户感知的体验质量（QoE）的变化。
