The standardization for Seamless IP Mobility between heterogeneous networks is being progressed according to each specific purpose of the organizations such as ITU-T ((International Telecommunications Union– Telecommunication), 3GPP(3rd Generation Partnership Project), IETF(Internet Engineering Task Force), and IEEE(Institute of Electrical and Electronics Engineers). [1] Specially VCC (Voice Call Continuity) for seamless voice continuity between heterogeneous networks using IMS (IP Multimedia Subsystem) of the next generation platform is being introduced into a few companies, and also MIH (Media Independent Handover) and MIP (Mobile IP) for IP mobility between heterogeneous networks are being customized by their internal situation. This article describes the idea to support IP Mobility between heterogeneous networks in the network which IMS platform is deployed and only supports the mobility for the voice by the type of AS (Application Server).

In 2020, LGU+`s 5G Backhaul will be the All in One Transport Network. We should be make decrease network equipment capex, operator`s opex, service provision time. Also we should be increase operation efficiency and service quality. LGU+ considering a converged network that simplify and a single platform with simple network structure. The shape is will be IP/MPLS + MPLS-TP + OTN & ROADM.
