Then, we present a new configuration and accordingly data/control realization of 5G EPS (Evolved Packet System) based on a carrier-grade hypervisor and an intelligent core server (IC server) to provide virtualization and flexibility to the network. In addition, we define two new entities hAN (heterogeneous access network) and TNT-Gateway (TENANT Gateway) for access and core, respectively and define their functions and data/signaling connections. Some important advantages of these configurations are: 1) cost reduction, 2) network efficiency improvement, and 3) increase of network flexibility and service availability which approaches LTE to 5G. https://mjee.modares.ac.ir/article_13014_bafd4215ef527cf0e0b2f843ce2ee763.pdf
