Gap analysis for adapting the distributed mobility management model in 4G/5G mobile networks

摘要

In this paper, we provide a gap analysis to apply an IP-based distributed mobility management architecture that is standard in IETF to a 3GPP mobile core network. The IP distributed mobility management deployment model is obtained from the five models defined by the IETF DMM WG, and the 3GPP mobile core network is a 4G-based extended architecture and 5G core network study architecture. We conduct the gap analysis to describe the technology that requires current standards-based applicability and extension for technical interoperability between two standardization organizations.
