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).

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.

Lifetime Achievement, second award presented

March 8, 2018

On Monday of last week, the 3GPP RAN2 Chairman - Richard Burbidge - presented Don Zelmer with the 3GPP Lifetime Achievement Award on behalf of the project.

Don Zelmer has participated in 3GPP since our creation, attending over 600 TSG and WG meetings and taking on the Rapporteur role for several study and work items, including work on Public Warning Systems (PWS), future FDD HSPA Evolution and for the introduction of the UMTS850 (Band V) in to 3GPP specifications.

He has served as Vice Chair of 3GPP TSG RAN (1999-2009) and now attends TSG RAN & RAN WG#2 as a lead AT&T Delegate. Don regularly attends the 3GPP Project Coordination Group (PCG) and Organizational Partner’s meetings, as a member of the ATIS delegation.

In addition to his leadership in 3GPP, Don has regularly served as Chair of the ATIS Wireless Technologies and Systems Committee (WTSC), which is one of the primary North American drivers into 3GPP.


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.

Video Interview - On 5G Core Stage 3 Work

January 28, 2018

In our second video from the TSG#78 meetings, December 2017, Georg Mayer gives an update on the CT aspects of the 5G network, covering the Stage 3 level work for the completion of areas such as Slicing, the Service based architecture and the necessary transport protocols. 

The interview touches on these topics and brings in details of the significance of RESTful and the possible use of QUIC transport and security protocols from Release 16 onwards.
