1 Introduction

5G is the first generation of mobile networks that is by design addressing the wide range of

needs of the vertical industries. 5G offers unlimited mobile broadband experience, provides

massive connectivity for everything from human-held smart devices to sensors and machines,

and most importantly, it has the ability to support critical machine communications with instant

action and ultra-high reliability.

First 5G specifications are available with 3GPP Rel.15 where the focus was primarily to serve

mobile operator needs in terms of extreme mobile broadband services. A second release (3GPP

Rel.16) will be soon available end of 2019 that will include several features to support vertical

in terms of enablers for Industrial IoT and URLLC. However, this is only the initial step, further

enhancements and optimizations are still needed to design a 5G System that meets the

challenging requirements from the vertical industries. With this White Paper the 5GPPP

Architecture Working Group is going to summarize the finding from 5GPPP Phase 2 and Phase

3 projects with the aim to impact the coming standards releases.

The White Paper is organized as follows. The overall architecture in Chapter 2 provides several

enhancements to the 3GPP Rel.15 system architecture to address specific requirements from

vertical industries. Chapter 3 details the RAN architecture and the relevance of the edge to

enable local computing and local path to support diverse variety of requirements in terms of

latency, throughput and reliability. Chapter 4 complements previous chapter describing the CN

architecture and the infrastructure connectivity provided by the Transport Network architecture.

In order to achieve the required flexibility, the management and orchestration architecture plays

a key role as presented in Chapter 5. To enable different verticals and large variety of

requirements need to be supported, in Chapter 6 we present examples of architecture

deployments investigated and analysed in the 5GPPP projects. Finally, Chapter 7 summarizes

the standardization impact that the work done have already achieved in different standardization

bodies with special focus on 3GPP and ETSI.

2 Overall architecture

5G networks have been targeted to meet the requirements of a highly mobile and fully

connected society. The coexistence of human-centric and machine type applications will define

very diverse functional and performance requirements that 5G networks will have to support.

Within the 5G System (5GS), end-to-end (E2E) network slicing, service-based architecture,

Software-Defined Networking (SDN), and Network Functions Virtualisation (NFV) are seen as

the fundamental pillars to support the heterogeneous key performance indicators (KPIs) of the

new use cases in a cost-efficient way. The 5GS gives mobile network operators the unique

opportunities to offer new services to consumers, enterprises, verticals, and third-party tenants

by addressing their respective requirements. To this end, 5G Infrastructure Public Private

Partnership (5G PPP) Phase I/II collaborative research projects as well as standardisation bodies

have specified and developed the main elements of the 5G architecture.

2.1 Stakeholder roles in the 5G ecosystem

The 5G ecosystem should enable manufacturers, solution integrators, network and service

providers, and Small and Medium-sized Enterprises (SMEs) to efficiently compete and

cooperate, e.g., by means of virtualisation, standardised interfaces and protocols, or open APIs.

SMEs will be able to provide technological solutions which will be compatible with the overall

system, e.g., new hardware components in the infrastructure or software components in the

Management and Organization layers. Manufacturers and solution integrators can offer rapid

deployment enabled by virtualisation and standardised interfaces to increase the level of

innovation. Mobile Network Operators (MNOs) and infrastructure providers will create tailored

slices with specific functionalities and Over-The-Top applications and services to address

requirements of vertical industries.

[2-1] and [2-5] mainly focus on single-domain service provisioning, but do not elaborate on,

e.g., cross-operator scenarios. Additionally, the 3GPP roles are defined from the point of view

of an operator. 5G PPP Phase I/II collaborative research projects have extended these roles to

allow various possible customer-provider relationships between verticals, operators, and other

stakeholder, as shown in Figure 2-1 (adapted from [2-6]):

• Service Customer (SC): uses services that are offered by a Service Provider (SP). In the

context of 5G, vertical industries are considered as one of the major SCs.

• Service Provider (SP): comprises three sub-roles, depending on the service offered to the

SC: Communication Service Provider offering traditional telecom services, Digital Service

Provider offering digital services such as enhanced mobile broadband and IoT to various

vertical industries, or Network Slice as a Service (NSaaS) Provider offering a network slice

along with the services that it may support and configure. SPs design, build and operate

services using aggregated network services.

• Network Operator (NOP): in charge of orchestrating resources, potentially from multiple

virtualised infrastructure providers (VISP). The NOP uses aggregated virtualised

infrastructure services to design, build, and operate network services that are offered to SPs.

• Virtualisation Infrastructure Service Provider (VISP): Provides virtualised

infrastructure services and designs, builds, and operates virtualisation infrastructure(s) [2-1].

The infrastructure comprises networking (e.g., for mobile transport) and computing

resources (e.g., from computing platforms).

• Data Centre Service Provider (DCSP): Provides data centre services and designs, builds

and operates its data centres. A DCSP differs from a VISP by offering “raw” resources (i.e.,

host servers) in rather centralised locations and simple services for consumption of these

raw resources. A VISP rather offers access to a variety of resources by aggregating multiple

technology domains and making them accessible through a single API.

2.2 5G Enhanced Overall System Architecture

The prospects of network slicing, i.e., executing multiple logical mobile network instances on a

shared infrastructure, require a continuous reconciliation of customer-centric service level

agreements (SLAs) with infrastructure-level network performance capabilities. Service

customers, e.g., from the vertical industries, request the creation of (tele)communication

services by providing “customer-facing” on-demand service requirement descriptions to Service

Providers. In the past, operators executed such mapping in a manual manner on a limited

number of service/slice types (mainly mobile broadband, voice, and SMS). With an increased

number of such customer requests, an E2E framework for Service Creations and Service

Operations will therefore have to exhibit a significantly increased level of automation for the

lifecycle management of network slice instances.

On the Service Level, lifecycle management automation must be realized by closed-loop

Service Assurance, Service Fulfilment, and Service Orchestration functions (cf. Figure 2-2)

covering all lifecycle phases: preparation phase, instantiation, configuration and activation

phase, run-time phase, and decommissioning phase. Two fundamental technological enablers

include softwarisation, e.g., virtualisation of network functions, as well as software-defined,

programmable network functions and infrastructure resources. E2E Service Operations

functions interact with functions for Management of Domain Resources and Functions.

Example domains include RAN, Core & Transport Network, as well as NFV and MEC. Besides

orchestration, closed-loop procedures for resource fulfilment, resource assurance, and network

intelligence comprise building blocks within each management domain. On a more fine-grained

temporal and spatial level, domain-specific controllers, incl. SDN controllers, can be

programmed to efficiently execute policies and rules on the Resources and Functional Level.

Finally, a common platform, where data can be accessed by system entities from all levels, uses

scalable data exposure governance and access control mechanisms to provides services for data

acquisition, processing, abstraction, and distribution. This includes data related to subscribers, to

the network and underlying resources, to network slice and service instances, and, if required by

the vertical customer, to applications.
