Method and system for realizing network switching
A method and system for realizing network switching, and a mobile node are provided. An LMA receives a PBU message from a second MAG, wherein the PBU message carries identifier information of the mobile node, the IP address of a first interface, and the IP address of the second MAG. The LMA checks in the stored BCE whether the identifier information of the mobile node and the IP address of the first interface exist. If the existence is checked, the LMA continually judges whether the Proxy Care-of-Address in the BCE is the same as the Proxy Care-of-Address in the PBU message. If they are different, the LMA determines that the connection of the mobile node is a switchable connection, and determines that the mobile node has the ability of address preservation, then sends the IP address of the first interface to the second MAG.
