Introduction
The need to support different kinds of UEs (e.g., for the Internet of Things (IoT)), services, and technologies is driving
the technology revolution to a high-performance and highly efficient 3GPP system. The drivers include IoT, Virtual
Reality (VR), industrial control, ubiquitous on-demand coverage, as well as the opportunity to meet customized market
needs. These drivers require enhancements to the devices, services, and technologies well established by 3GPP. The key
objective with the 5G system is to be able to support new deployment scenarios to address diverse market segments.
This document compiles requirements that define a 5G system.
The 5G system is characterised, for example, by:
- Support for multiple access technologies
- Scalable and customizable network
- Advanced Key Performance Indicators (KPIs) (e.g., availability, latency, reliability, user experienced data rates,
area traffic capacity)
- Flexibility and programmability (e.g., network slicing, diverse mobility management, Network Function
Virtualization)
- Resource efficiency (both user plane and control plane)
- Seamless mobility in densely populated and heterogeneous environment
- Support for real time and non-real time multimedia services and applications with advanced Quality of
Experience (QoE)

4 Overview
Unlike previous 3GPP systems that attempted to provide a 'one size fits all' system, the 5G system is expected to be able
to provide optimized support for a variety of different services, different traffic loads, and different end user
communities. Various industry white papers, most notably, the NGMN 5G White Paper [2], describe a multi-faceted 5G
system capable of simultaneously supporting multiple combinations of reliability, latency, throughput, positioning, and
availability. This technology revolution is achievable with the introduction of new technologies, both in access and the
core, such as flexible, scalable assignment of network resources. In addition to increased flexibility and optimization, a
5G system needs to support stringent KPIs for latency, reliability, throughput, etc. Enhancements in the air interface
contribute to meeting these KPIs as do enhancements in the core network, such as network slicing, in-network caching
and hosting services closer to the end points.
ETSI
3GPP TS 22.261 version 15.6.0 Release 15 10 ETSI TS 122 261 V15.6.0 (2018-10)
A 5G system also supports new business models such as those for IoT and enterprise managed networks. Drivers for the
5G KPIs include services such as Unmanned Aerial Vehicle (UAV) control, Augmented Reality (AR), and factory
automation. Network flexibility enhancements support self-contained enterprise networks, installed and maintained by
network operators while being managed by the enterprise. Enhanced connection modes and evolved security facilitate
support of massive IoT, expected to include tens of millions of UEs sending and receiving data over the 5G network.
Flexible network operations are the mainstay of the 5G system. The capabilities to provide this flexibility include
network slicing, network capability exposure, scalability, and diverse mobility. Other network operations requirements
address the necessary control and data plane resource efficiencies, as well as network configurations that optimize
service delivery by minimizing routing between end users and application servers. Enhanced charging and security
mechanisms handle new types of UEs connecting to the network in different ways.
Mobile Broadband (MBB) enhancements aim to meet a number of new KPIs. These pertain to high data rates, high user
density, high user mobility, highly variable data rates, deployment, and coverage. High data rates are driven by the
increasing use of data for services such as streaming (e.g., video, music, and user generated content), interactive
services (e.g., AR), and IoT. These services come with stringent requirements for user experienced data rates as well as
associated requirements for latency to meet service requirements. Additionally, increased coverage in densely populated
areas such as sports arenas, urban areas, and transportation hubs has become essential for pedestrians and users in urban
vehicles. New KPIs on traffic and connection density enable both the transport of high volumes of data traffic per area
(traffic density) and transport of data for a high number of connections (e.g., UE density or connection density). Many
UEs are expected to support a variety of services which exchange either a very large (e.g., streaming video) or very
small (e.g., data burst) amount of data. The 5G system will handle this variability in a resource efficient manner. All of
these cases introduce new deployment requirements for indoor and outdoor, local area connectivity, high user density,
wide area connectivity, and UEs travelling at high speeds.
Another aspect of 5G KPIs includes requirements for various combinations of latency and reliability, as well as higher
accuracy for positioning. These KPIs are driven by support for both commercial and public safety services. On the
commercial side, industrial control, industrial automation, UAV control, and AR are examples of those services.
Services such as UAV control will require more precise positioning information that includes altitude, speed, and
direction, in addition to horizontal coordinates.
Support for Massive Internet of Things (MIoT) brings many new requirements in addition to those for the enhanced
KPIs. The expansion of connected things introduces a need for significant improvements in resource efficiency in all
system components (e.g., UEs, IoT devices, radio, access network, core network).
The 5G system also aims to enhance its capability to meet KPIs that emerging V2X applications require. For these
advanced applications, the requirements, such as data rate, reliability, latency, communication range and speed, are
made more stringent.
5 High-level requirements
5.1 Migration to 5G
5.1.1 Description
The 5G system supports most of the existing EPS services, in addition to many new services. The existing EPS services
may be accessed using the new 5G access technologies even where the EPS specifications might indicate E-UTRA(N)
only. Only new or changed service requirements for new or changed services are specified in this TS. The few EPS
capabilities that are not supported by the 5G system are identified in clause 5.1.2.2 below.
5.1.2 Requirements
5.1.2.1 Interworking between 5G systems
The 5G system shall support a UE with a 5G subscription roaming into a 5G Visited Mobile Network which has a
roaming agreement with the UE's 5G Home Mobile Network.
The 5G system shall enable a Visited Mobile Network to provide support for establishing home network provided data
connectivity as well as visited network provided data connectivity.
ETSI
3GPP TS 22.261 version 15.6.0 Release 15 11 ETSI TS 122 261 V15.6.0 (2018-10)
The 5G system shall enable a Visited Mobile Network to provide support for services provided in the home network as
well as provide services in the visited network. Whether a service is provided in the visited network or in the home
network is determined on a service by service basis.
The 5G system shall provide a mechanism for a network operator to limit access
