3GPP 5G Security

August 6, 2018

By Anand R. Prasad, Alf Zugenmaier, Adrian Escott and Mirko Cano Soveri

In December 2017, the Non-Standalone (aka. NSA) specifications for 5G new radio (NR) were approved, followed in June 2018, by the Standalone specifications – completing the radio part of 5G Phase 1 (3GPP Release 15). The 3GPP Security Working Group (SA3) has been involved from the outset of the work. In this article we briefly introduce security for both Non-Standalone [1] and the Standalone NR 5G system [2].

The 5G system is an evolution of the 4G mobile communication systems. Accordingly, the 5G security architecture is designed to integrate 4G equivalent security. In addition, the reassessment of other security threats such as attacks on radio interfaces, signalling plane, user plane, masquerading, privacy, replay, bidding down, man-in-the-middle and inter-operator security issues have also been taken in to account for 5G and will lead to further security enhancements. This article gives an overview of 5G Phase 1 security as described in Release 15 specifications [1,2]


Lifetime Award goes to Security Specialist

The 3GPP lifetime achievement award has gone to Günther Horn in recognition of his contribution to the work of the SA3 - Security Group, as forty-two SA3 colleagues submit a joint submission for this popular award nomination. 


Technical Journal articles on 3GPP 5G

July 19, 2018

Based on the Journal’s Forword, by Erik Guttman, Frank Mademann, Anand R. Prasad:

3GPP experts have generously contributed to a special “3GPP 5G Specifications” edition of the Journal of ICT Standardization, by River Publishers.

The diverse range of the 5G work within 3GPP groups is reflected in the Journal. Two articles “5G NR radio interface” and “NG Radio Access Network (NG-RAN)” take the reader through the work on NR, the coexistence of NR and LTE and how the specifications contribute to the IMT-2020 goals for a futuristic 5G network.

Another area of significant development is the 5G Core Network (5GC) and overall system. “The 5G System Architecture” article here offers an introduction and explains some of its key characteristics.

In “Path to 5G: A Control Plane Perspective” some of the most significant system developments from earlier generations to 5G are considered in more detail.

RESTful APIs for the 5G Service Based Architecture” explores how the 5GC internal communication has been specified using a RESTful design, and explains how the protocols and interfaces developed provide opportunities for future integration with other systems.


RAN3 Clocks up the 100

June 28, 2018

By Gino Masini, Sasha Sirotkin and Yin Gao

May 2018 will be remembered by some for two very special events; the finalization of the Non-Standalone NR specification and the RAN3 centennial celebration. In Busan, Korea.

3GPP RAN WG3 took some time off after heated discussions, hectic drafting and careful ASN.1 polishing for a well-deserved party at the RAN3#100 meeting.

Different opinions about intricate details of XnAP Information Element definitions have been put aside, questions for clarification forgotten and replaced by compliments and toasts to recognize this significant landmark.

There was singing at dinner (Lyrics in R3-183485) and stories told about the old days when meeting schedules were less hectic and summers were longer. There were also awards made, notably to some of the characters that have made RAN3 a special place to be.


Webinar - Working towards full 5G in Rel-16

July 3, 2018

See our latest webinar, presented by Balazs Bertenyi, on the progress made at RAN#80, including details of:

  • the major milestone of freezing 5G standalone specifications;
  • the Rel-15 late drop to address essential market needs of migration to 5G;
  • and on the Rel-16 work program: with planned features to facilitate fulfilling the full 5G vision.
