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
