摘要： A method, apparatus, and device for managing binding information on the network side are provided. The method includes the following steps: an entity on a network side sends a Binding Revocation Indication (BRI) message to an entity which stores binding relations of mobile nodes (MNs), where the binding relation includes a mapping between a home of address (HoA) of an MN and plurality of care of addresses (CoAs) of the MN and the BRI message includes at least one CoA ID; and the entity which stores the binding relations of MNs deletes the corresponding binding relation of at least one CoA ID in the BRI message after receiving the BRI message from the entity on the network side. Thus, with the present invention, the network side can delete the binding relation between a specified CoA and an HoA in the case of plurality of CoAs, which makes it easier to maintain corresponding binding relations.

摘要： 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.
