Method, apparatus, and device for managing binding information on network side

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.

1. A method for managing binding information on a network side, the method comprising:
sending, by an entity on the network side, a Binding Revocation Indication (BRI) message to an entity which stores a plurality of binding relations of a mobile node (MN),
where the MN has a plurality of care of addresses (CoAs) associated with multiple interfaces of the MN,where the BRI message is configured to instruct the entity which stores plurality of the binding relations of the MN to delete at least one binding relation from the plurality of binding relations of the MN, each of the at least one binding relation being specified by the BRI message,wherein the plurality of binding relations comprise a plurality of mappings between a home address (HoA) of the MN and the plurality of CoAs of the MN; and receiving, by the entity on the network side, a binding revocation acknowledgement (BRA) message from the entity which stores the plurality of binding relations of the MN, where the BRA message indicates that the entity which stores the plurality of binding relations of the MN has deleted the at least one specified binding relation of the MN from the plurality of binding relations of the MN.
