1. A method for implementing a software-defined private mobile network (SD-PMN) for an entity, the method comprising:
at a physical location of the entity, deploying a first set of control plane components for the SD-PMN, the first set of control plane components comprising a user-plane function (UPF);
at an SD-WAN (software-defined wide area network) PoP (point of presence) belonging to a provider of the SD-PMN, deploying a second set of control plane components for the SD-PMN, the second set of control plane components comprising a security gateway, an AMF (access and mobility management function), an SMF (session management function), and a subscriber database that stores data associated with users of the SD-PMN; and
using an SD-WAN edge device located at the physical location of the entity and an SD-WAN gateway located at the SD-WAN POP to establish a connection from the physical location of the entity to the SD-WAN POP; wherein
the physical location of the entity is one of a plurality of physical locations of the entity;
at least one SD-WAN edge router is deployed at each physical location in the plurality of physical locations of the entity;
the SD-WAN POP is one of a plurality of SD-WAN PoPs belonging to the SD-PMN provider;
each SD-WAN POP in the plurality of SD-WAN PoPs is connected to the SD-PMN by a respective SD-WAN gateway deployed to the SD-WAN POP;
each SD-WAN POP in the plurality of SD-WAN PoPs includes a same set of network elements, the same set of network elements comprising at least the security gateway, AMF, SMF, and subscriber database that stores data associated with users of the SD-PMN;
each SD-WAN edge router in the plurality of SD-WAN edge routers is assigned at least a primary SD-WAN gateway associated with a first SD-WAN POP and a secondary SD-WAN gateway associated with a second SD-WAN POP; and
the same set of network elements share a same set of common IP (Internet protocol) addresses across the plurality of SD-WAN PoPs including the first and second SD-WAN POPs.
