Abstract

   This document presents considerations related to open issues with
   upcoming new communication systems denoted as 5G aiming to set a
   basis for documenting problem space, use-cases, and potential
   solutions related to next-generation network infrastructure.  The
   draft reviews currently investigated topics, including both inputs
   from IETF and from other SDOs as well as research activities.
   Further the outcome of recent discussions at side sessions during
   IETF meetings are recaptured to help identifying a starting point for
   future thoughts.

1.  Introduction

   This document focuses on IP architecture and protocol aspects related
   to upcoming new communication system infrastructure.  This envisaged
   5G system is foreseen to be available from 2020 onwards to provide a
   converged Information and Communication Technology (ICT) ecosystem.
   The offered broad spectrum of fixed and mobile services will be
   characterised mainly by improved flexibility and efficient usage of
   available resources to support services' demands with partially
   contradicting requirements.  A new highly re-configurable
