PMIPv6 facilitates IP mobility by keeping these mobility parameters constant throughout the PMIPv6
domain:

PMIPv6 Terminologies:
Proxy Mobile IPv6 DomainA network where the mobility management of a mobile node is
handled using the PMIPv6 protocol. The domain consists of network entities, such as MAG and
LMA, between which Proxy Binding can be maintained on behalf of the mobile nodes.

LMA, between which Proxy Binding can be maintained on behalf of the mobile nodes.

Local Mobility Anchor (LMA)LMA is the home agent for the mobile node in a PMIPv6 domain. It
is the topological anchor point for the mobile node's home network prefix and is the entity that
manages the mobile node's binding state.

•
Mobile Access Gateway (MAG)MAG is a function on an access router that manages the
mobility−related signaling for a mobile node that is attached to its access link. It is responsible for
tracking the mobile node's movements to and from the access link.

•
Mobile Node (MN)An IP host or router with mobility managed by the network. The MN can be an
IPv4−only node, IPv6−only node, or a dual−stack node and is not required to participate in any IP
mobility related signaling for achieving mobility for an IP address that is obtained in that PMIPv6
domain.

•
Network Access Identifier (NAI)NAI is the user identity submitted by the client during network
access authentication. In roaming, the purpose of the NAI is to identify the user and assist in the
routing of the authentication request. The standard syntax is "user@realm", or as defined in rfc 4282.
