Abstract
An apparatus comprising a mobile access gateway (MAG) configured to register an Internet Protocol (IP) address for a mobile node (MN) with a local mobility anchor (LMA) to allow proxy mobile IP version 6 (PMIPv6) mobility management for the MN, wherein the MAG communicates a query message that comprises a PMIPv6 service name to a Domain Name Service (DNS) and obtains the IP address of the LMA from the DNS. Also disclosed is a network component comprising at least one processor coupled to a memory and configured to send a DNS query for a plurality of Service Resource Records (SRV RRs), and receive a DNS reply that comprises a plurality of Fully Qualified Domain Names (FQDNs) for a plurality of LMAs, wherein the DNS query comprises a Proxy Mobile Internet Protocol version 6 (PMIPv6) service name, a protocol name, and a domain name.
