Abstract

   In this document, we provide a gap analysis to apply DMM deplyment
   models to a 3GPP mobile core network. The DMM deployment models are
   described into five models for separation control and data plane,
   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.

1. Introduction

   The Distributed Mobility Management (DMM) solution has been
   investigated to re-locate the current anchor functions in a
   distributed manner and to provide different IP session management
   characteristics for each mobile node session. For deploying DMM,
   five different models are described in [dmm-deployment-models] based
   on the network entities according to the location(access or home)
   and functionality(control or data).

   3GPP has the responsibility to standardize cellular mobile networks,
   and the functional separation of the gateway in 4G Evolved Packet
   Core(EPC) netowrk has also been studied to divide the gateway into
   a control and data plane, defining an interface between them, and
