Patent ID: 11044652

Abstract:
Embodiments of the present disclosure disclose a handover method and an apparatus, so as to reduce a handover delay in a process of handing over an MN from a previous access network to a new access network. The method includes: sending, by the MN, first instruction information to a NAR by using a PAR, where the first instruction information is used to instruct the NAR to construct a care-of test initialization message and send the care-of test initialization message to a CN, and the care-of test initialization message includes an NCoA of the MN and is used to request a care-of keygen token from the CN based on the NCoA; handing over the MN from the PAR to the NAR; receiving, by the MN, the care-of keygen token sent by the NAR from the CN; and binding the MN with the CN based on the care-of keygen token.
