  • Patent number: 8289862
    Abstract: Methods and apparatuses are provided for supporting mobility in a Proxy Mobile Internet Protocol (“IP”) network without having a mobile node (“MN”) to participate in certain mobility related signaling. Instead, a proxy agent might implement functions of a mobile access gateway (“MAG”) in a Proxy Mobile Internet Protocol Version 6 (“IPv6”) network. The proxy agent, rather than the MN, might send a request to a Dynamic Host Configuration Protocol (“DHCP”) server, and receive back a local mobility anchor address (“LMAA”) of a local mobility anchor (“LMA”). The proxy agent might instead perform a Domain Name System (“DNS”) lookup for the LMAA of the LMA first; in response to a failure to receive the LMAA, the proxy agent might then send the request to the DHCP server to receive the LMAA. The proxy agent might further update DNS information of the MN.
