The 3GPP Rel-16 5G System focuses on enabling support for Industrial Internet of Things (IIoT) for Industry 4.0. Building blocks of 5G supporting use cases and requirements from the manufacturing sector are extreme mobile broadband, massive machine-type communication, ultra-reliable critical machine communication, non-public networks, time sensitive communication, 5G LAN communication, precise positioning. While for all of them, security plays an important role, the focus of this paper is on the 3GPP Rel-16 architecture and security concept of 5GS Non-Public Networks.We conclude with insights on the challenges for using 5G in the Operational Technology Industry.

The aim of the book is to educate government agencies, operators, vendors and other regulatory institutions how LTE can be deployed to serve public safety market and offer regulatory / public safety features. It is written in such a way that it can be understood by both technical and non-technical personnel with just introductory knowledge in wireless communication. Some sections and chapters about public safety services offered by LTE network are intended to be understood by anyone with no knowledge in wireless communication.


Proximity Services

July 2015

·

18 Reads

This chapter provides a detailed description of proximity services as specified in 3GPP. “Proximity Services” (ProSe) refers to services that can be provided to devices when they are in close proximity to each other. The chapter provides also an overview of discovery models, modes, procedures, and direct communication procedures that are specified in 3GPP Release 12. It also provides insights into how Proximity Services can be supported in the LTE network and LTE device.


Introduction to LTE/SAE

July 2015

·

7 Reads

This chapter provides an overview of Long-Term Evolution (LTE) including insights into the role of 3rd Generation Partnership Program (3GPP) in developing new technologies and technology/business drivers for LTE. It presents a high-level overview of nonroaming and roaming architectures with explanation of concepts such as session and mobility management, network sharing, and multicast broadcast multimedia services. It also provides a high-level overview of Policy and Charging Control/IP Multimedia Subsystem (PCC/IMS) architectures and mechanisms to support voice and Short Message Service (SMS) in LTE.



Group Communication Over LTE

July 2015

·

5 Reads

This chapter provides details of group communication services as specified in 3GPP Release 12. This includes the architectural framework adopted for unicast and broadcast delivery of voice and data in order to effectively support group communication. It also highlights different use cases and how group communication solutions apply for these use cases.



Regulatory Features

July 2015

·

11 Reads

This chapter provides an overview of regulatory features and priority services that should be supported by Long-Term Evolution (LTE) networks including public safety networks. Most important features are emergency calls to a public safety answering point (fire, police, and ambulance), multimedia priority services to allow certain people making priority calls even in network congestion situations and public warning systems for broadcasting warning messages in special areas about impending emergency situations. Last but not the least, the possibility to intercept any communication between is a requirement mobile network operators have to fulfill in each country worldwide.


Summary and Outlook

July 2015

·

5 Reads

This chapter provides a summary of what was explained in previous parts of this book. It is meant as a wrap-up of the LTE and LTE for Public Safety principles, how LTE impacts people's daily lives and how public safety features and services can help to enhance people's safety and security. It is mainly intended to provide a summary of the concepts addressed in the book and to provide an outlook on the future of public safety networks.

... 3GPP outlines more information on NPNs in TS 22.261 [49]. The authors in [50,51] review the outlined security measures for NPNs along with potential use cases and considerations. Use cases for NPNs are also discussed in [52], which include emergency critical communications, smart city video surveillance, and services with Time-Sensitive Networking (TSN). ...

... 4G and 5G mobile technologies are leading the way to device to device (D2D) communications, which due to the mobile device density gives the tools for the extension of the terminal coverage when the network is damaged. Many applications and protocols [4]- [6] were proposed for public safety services based on global mobile network proximity service [7]. Since Release 11, the Third-Generation-Partnership-Project (3GPP) started to develop the specifications of new protocols and services for supporting public safety services. ...

... Mission critical users (such as police officers, border guards, civil protection staff, ambulance personnel, and fire and rescue) need reliable communications, high availability and security, that cannot be matched without multiple technological enablers. With suppliers now offering more LTE solutions, countries building national networks and with law enforcements' changing expectations surrounding their technology usage, it is evident broadband is the future of critical communications [22]. In the scope of the investigation for the potential integration of MC communications within commercially deployed broadband standards, as already performed by various market actors at the global level, the Long Term Evolution-Advanced (LTE-A) mobile radio technology has been assessed as a reference candidate technology, suitable for the development of the committed PS systems [7]. ...
