    • A route switching method, when a mobile node is switching between access routers, the method comprises: the second access router sending a context transfer message to the third access router, the third access router updating a Cache for Destination Terminal and a Cache for Source Terminal in a cache of the third access router according to the context transfer message; the second access router updating its cache according to the context transfer message, and updating a Cache for Destination Terminal in a cache of a first access router. Several route switching methods and route switching systems are also involved. Based on the Context Transfer Protocol, it enables the access router to transfer the address information of the mobile node associated with a session connection by the context transfer message directly during the switching, without the process in which the new access router inquires the routing manager, thereby reducing the delay caused by inquiring the routing manager, and thus decreasing the possibility of message lost.
    • 一种路由切换方法,当移动节点在接入路由器之间切换时,所述方法包括:所述第二接入路由器向所述第三接入路由器发送上下文传送消息,所述第三接入路由器更新目的地终端的缓存和源终端的缓存 在根据上下文传送消息的第三接入路由器的缓存中; 第二接入路由器根据上下文传送消息更新其高速缓存,并且更新第一接入路由器的高速缓存中的目的终端缓存。 还涉及到几种路由切换方法和路由交换系统。 基于上下文传输协议,它使得接入路由器能够在切换期间直接传递上下文传送消息中与会话连接相关联的移动节点的地址信息,而不需要新接入路由器询问路由管理器的过程, 从而减少查询路由管理器造成的延迟,从而降低消息丢失的可能性。
