              Mobility Management based on Source Routing 
          draft-wei-dmm-source-routing-mobility-management-00

Abstract

   This document explores how mobility management could be provided
   based on source routing like solutions and take SRv6 as an example
   for 5G LAN service.

1  Introduction

   The 5G network is designed aims at three scenarios which are eMBB
   (enhanced Mobile Broad Band), uRLLC (ultra-Reliable Low latency
   Communication ), and mMTC (massive Machine Type Communication). The
   goal of 5G is to provide network services for various application
   scenarios not limited to traditional MBB service. 

   One of the promises of 5G is the convergence of fixed and mobile
   networks, and providing LAN (Local Area Network) services in 5G
   networks is a new communication requirement. 5G LAN has many
   potential application scenarios, for example, provide communication
   for home service in residential environment which will solve many
   coverage and QoS problems that home owners are suffering with the
   current solutions; provide enterprise communication service in
   enterprise environment to interwork with and enhance existing WLAN
   and fixed LANs in the enterprise and as a replacement LAN technology
   that eliminates the need for other WLAN and fixed LAN deployments and
   provide with a wider area coverage using the cellular radio and
   greater mobility for UEs. 

   Communication between UEs in a 5G LAN is a full mesh communication
   mode, and UEs that belong to the same LAN can communicate with each
   other, and the UE has mobility characteristics and may move between
   different network locations. The traditional GTP tunnel-based
   solution needs to establish a tunnel between network nodes in a full
