Methods and apparatus for mobile ip home agent clustering

For processing from roamed to the mobile IP method and device for external mechanism (212) mobile node (210) login request of the is claimed. Automatically (202) in multiple support mobile AND the the first local the local proxy, wherein the is transmitted to automatically (202-208) are multiple the local with the login request of virtual local proxy address. The login request which is transmitted to the local proxies a second the local automatically (204), provided with multiple local proxies the second the local to act (204) (210) and external mechanism (212) founds to bind (216) between the mobile node. The the first local multiple local proxy shaft (202) (210) and external mechanism (212) founds temporary connecting between the mobile node. And the second the local from multiple local proxy automatically (204) and a registration of acknowledge. When the second the local from multiple local proxy automatically (204) for receiving the register acknowledge; the temporary connecting is renewed to found the terminal (216). The register acknowledge which is transmitted to the external mechanism of the temporary connecting marks (212).
