Title: METHOD FOR ACTIVE RECONFIGURATION OF NETWORK PREFIX IN PROXY MOBILE IPV6
Abstract:
Disclosed is a method for active reconfiguration of a network prefix in a proxy mobile IPv6. The method comprises: (1) when the renumbering of a network prefix (HNP) of a mobile node (MN) occurs, a local mobility anchor (LMA) allocates a new HNP to the MN; (2) the LMA sends an update notification (UPN) message to a mobility access gateway (MAG), wherein the message includes an HNP option and an MN identifier option; (3) when the MAG determines that the LMA configures the new HNP for the MN according to the received UPN, and the MAG constructs a router advertisement (RA) message according to the UPN and sends same to the MN; (4) the MAG sends an update acknowledgement (UPA) message to the LMA so as to notify the update completion of prefix information; and (5) after determining that the HNP changes according to the received router advertisement (RA) message, the MN uses the new HNP to configure a communication address. The present invention can effectively reduce an update time delay of an HNP.
