METHOD AND APPARATUS FOR ADDRESS VERIFICATION DURING MULTIPLE ADDRESSES REGISTRATION

摘要

In this present invention, when the HA is performing Bulk Registration for a Multimode Node, the HA will tagged those CoAs specified within the single BU as unverified. A verification mechanism implemented at the HA will be triggered to test the addressability of the unverified CoA before using the said unverified CoA. The method of verification involves the HA to send an acknowledgment message to an unverified CoA of the Multimode Node to test the said unverified CoA for its addressability. When the Multimode Node receives the acknowledgment message from the HA, the Multimode Node replies the HA with another single BU. Upon the receipt of the second single BU from the Multimode Node, the HA can then verify that the said unverified CoA of the Multimode Node.
