Critical Comms on Show

May 17, 2018

The 20th Critical Communications World has attracted the professional user community to Berlin this week, for the industry’s top conference and exhibition. Both ETSI and 3GPP leaders joined 3GPP market partner TCCA at the exhibition, on the awards program and speaking at the conference.

CComs features diagErik Guttman and Georg Mayer spoke on the 3GPP MC topic, highlighting recent enhancements to Mission Critical Push-to-talk (MCPTT), MCVideo and MCData as well as looking forward to 5G future work.

At the International Critical Communications Awards (ICCA 2018), on the first evening of CCW, we presented a glass trophy to the TCCA in recognition of their 20 years of work, through the TETRA Congresses and the CCW conference series.

A stalwart of SA6 and the TETRA communities – Dave Chater-Lea – was also a winner at ICCA, receiving the Industry’s award for an ‘Outstanding Contribution to Critical Communications’.

Launch of the 3GPP CVD process

April 18, 2018

Under the guidance of our security group (SA3) and partner organization’s experts, we are able to announce that the 3GPP Coordinated Vulnerability Disclosure (CVD) process is now up-and-running.

The CVD will allow suspected or proven vulnerability caused by errors, omissions or ambiguities in our Technical Specifications to be reported and quickly forwarded to the appropriate 3GPP Group, to analyse and resolve the problem.

This is the first time that we have put a process in place for this activity, formalizing how individuals or organizations can provide information on vulnerabilities related to our deliverables.

Management, Orchestration and Charging for 5G networks

(Network Slicing on the way)

March 22, 2018

By Thomas Tovinger, 3GPP SA5 Chairman

In December 2017, 3GPP passed two major milestones for 5G by approving the first set of 5G NR specs and by putting in place the 5G Phase 1 System Architecture. These achievements have brought about the need for new management standards, as 5G adds to the ever-growing size and complexity of telecom systems.

3GPP management standards from working group SA5 are approaching another major milestone for 5G. With our studies on the 5G management architecture, network slicing and charging completed last year, we are now well under way with the normative work for the first phase in 3GPP Release 15, which includes building up a new service-oriented management architecture and all the necessary functionalities for management and charging for 5G networks.

SA5’s current work also includes several other work/study items such as management of QoE measurement collection and new technologies for RESTful management protocols. However, this article will focus on the new 5G Rel-15 architecture and the main functionalities, including charging.


Towards a better Public Warning System (ePWS)

April 11, 2018

By Hyounhee Koo (SyncTechno), ePWS rapporteur

Additional requirements for an enhanced Public Warning System (ePWS) have been agreed at the recent 3GPP TSG SA#79 meeting, as an update to Technical Specification (TS) 22.268.

3GPP Public Warning Systems were first specified in Release 8, allowing for direct warnings to be sent to mobile users on conventional User Equipment (PWS-UE), capable of displaying a text-based and language-dependent Warning Notification.

Since that time, there has been a growth in the number of mobile devices with little or no user interface - including wrist bands, sensors and cameras – many of which are not able to display Warning Notifications. The recent growth in the number of IoT devices - not used by human users – also highlights the need for an alternative to text based Warning Notifications. If those devices can be made aware of the type of incident (e.g. a fire or flood) in some other way than with a text message, then they may take preventive actions (e.g. lift go to ground floor automatically).

Optimizing media and radio signal processing for 5G

March 20, 2018

With the approval of the first 5G NR specifications, the industry is now moving toward the development and deployment phases, where design objectives of the new systems have to be realized. Kyunghun Jung, the co-author of "Media and Radio Signal Processing for Mobile Communications" looks at these phases and at the need to identify where standards remain silent.

By Kyunghun Jung, former 3GPP SA4 Vice Chairman

As the work to develop media and radio signaling standards for 5G progresses toward the realization stage, experiences of developers and operators reveal opportunities for further refinement of the standards while still allowing differentiation of products and services.

As there are limitations on what can be specified in the standards, extracting maximum service quality and network capacity from new systems requires developers and operators to understand the media and radio signal processing operations of devices and networks, and locate the opportunities to innovate within the boundary of standards.

Although compression and transmission of media have been playing fundamental roles in 3GPP systems, signal processing operations previously not attempted, such as 360 media or transmission faster than conversational class, may impose unprecedented constraints. Newly introduced technical elements or system architectures can make well-proven approaches insufficient or unnecessary, and features that have been taken for granted may not be supported in new systems.
