Next-generation network promises to integrate cross-domain carriers; thus, infrastructure can be provided as a service. 5G-PPP's vision is directed toward solving existing 4G LTE mobility challenges that congest core networks, disrupt multimedia and data transfer in high mobility situations such as trains or cars. This research adopts 5G methodology by using software-defined networking (SDN) to propose a novel mobile IP framework that facilitates seamless handover, ensures session continuity in standard and wide area coverage, and extends residential/enterprise indoor services across carriers under service level agreement while ensuring effective offload mechanism to avoid core network congestion. Performance excels existing protocols in setup and handover delays such as eliminating out-band signaling in bearer setup/release and isolating users' packets in virtual paths. Handover across cities in wide area motion becomes feasible with lower latency than LTE handover inside city. Extending indoor services across carriers becomes equivalent to LTE bearer setup inside a single carrier's PDN.
