    • Provided is a network-based mobility supporting method for supporting mobility of a node not having a mobility supporting function. The network-based mobility supporting method which is performed by a plurality of agents that connect a plurality of access networks to an Internet protocol core network integrating the plurality of access networks, includes: acquiring address information of a mobile node connected to an access point from the access point; transmitting the address information of the mobile node and layer 3 address information of an agent to a management unit which is located on the Internet protocol core network and manages the plurality of access networks, and registering a location of the mobile node; transmitting the layer 3 address information of the correspondent agent to the mobile node, in order to allow the mobile node to transmit a data packet to the agent; and receiving and transmitting the data packet between the mobile node and a correspondent node in consideration of the address information of the mobile node and information registered in the management unit. Therefore, it is possible to provide high-speed mobility to a mobile node.
    • 提供了一种用于支持不具有移动性支持功能的节点的移动性的基于网络的移动性支持方法。 由将多个接入网络连接到集成多个接入网络的因特网协议核心网络的多个代理执行的基于网络的移动性支持方法包括:从连接到接入点的移动节点获取地址信息, 接入点; 将代理的地址信息和代理的地址信息发送到位于因特网协议核心网上的管理单元,并管理多个接入网络,并登记移动节点的位置; 向移动节点发送对方代理的层3地址信息,以便允许移动节点向代理发送数据包; 考虑到移动节点的地址信息和登记在管理单元中的信息,在移动节点和通信节点之间接收和发送数据分组。 因此,可以向移动节点提供高速移动性。
