NEMO Overview
When enabled through a feature license key, the system includes NEMO support for a Mobile IPv4 Network Mobility
(NEMO-HA) on the P-GW platform to terminate Mobile IPv4 based NEMO connections from Mobile Routers (MRs)
that attach to an Enterprise PDN. The NEMO functionality allows bi-directional communication that is application-
agnostic between users behind the MR and users or resources on Fixed Network sites.
The same NEMO4G-HA service and its bound Loopback IP address supports NEMO connections whose underlying
PDN connection comes through GTP S5 (4G access) or PMIPv6 S2a (eHRPD access).
The following figure shows a high-level view of LTE NEMOv4 Architecture.

Use Cases
The following use cases are supported by NEMO in LTE:
1. Stationary - Applications, like branch offices, with a mobile router that does not require mobility.
2. Nomadic - Applications that use a mobile router that does not move while in service, but that may be moved to a
different location and brought back on service (e.g. a kiosk showing up in a mall one day and in a different
location the next day or month).
3. Moveable - Applications that need to maintain Dynamic Mobile Network Routing (DMNR) service operational
while moving and crossing PDSN boundaries, such as public safety vehicles. Service continuity is handled by
the mobility protocols (Mobile IP in 3G and GTP in LTE).
