Third-generation Mobility Anchor (3GMA) is the default gateway for Packet Data Serving Node (PDSN)/General Packet Radio Service (GPRS) Support Node (GGSN). A 3GMA node is placed on Gi interface of the PDSN/GGSN to serve as an anchor point for 3G User Equipments (UEs). Gi interface is the reference point between a GPRS network and an external packet data network. 3GMA node works as a DHCP server towards GGSN/PDSN, and as an LMA towards a WiFi MAG. 3GMA node assigns an IP address and responds to DHCP messages from GGSN/PDSN. UEs are configured with a specific Access Point Names (APNs); when a UE connects to this APN, PDSN/ GGSN is configured to operate in Proxy DHCP mode, instead of using local address pool. In 3GMA mode, the IP address assigned to the mobile is obtained from an external DHCP server (3GMA node). Local Mobility Anchor (LMA) functionality described in RFC 5213 can also be configured in 3GMA mode.

Local Mobility Anchor (LMA) is the home agent for a mobile node (MN) in a Proxy Mobile IPv6 (PMIPv6) domain. It is the topological anchor point for MN home network prefixes and manages the binding state of an MN. An LMA has the functional capabilities of a home agent as defined in the Mobile IPv6 base specification (RFC 3775) along with the capabilities required for supporting the PMIPv6 protocol.

Note	Use the dynamic mag learning command to enable LMA to accept Proxy Mobile IPv6 (PMIPv6) signaling messages from any Mobile Access Gateway (MAG) that is not configured locally.

Mobile node (MN) is an IP host and the mobility of the MN is managed by a network. MN can be an IPv4-only node, an IPv6-only node, or a dual-stack node, which is a node with IPv4 and IPv6 protocol stacks. MN is not required to participate in any IP mobility-related signaling for achieving mobility for an IP address or a prefix that is obtained in the Proxy Mobile IPv6 (PMIPv6) domain.

A radio access type (RAT) refers to the method of allocating radio resources in a wireless network for communication in the uplink (user to network) and downlink (network to user). RAT indicates the type of radio technology used to access a Core Network (CN), which is the central part of a telecommunication network that provides various services to customers who are connected by the access network. RAT is implemented by the radio access network (RAN) that resides between a device such as a mobile phone, a computer, or any remotely controlled machine, and provides connection with its CN. Mobile phones and other wireless connected devices are known as user equipment (UE). Examples of RAT types include Worldwide Interoperability for Microwave Access (WiMAX), Wireless Local Area Network (WLAN), and 3GPP
