5G Phase 1 underway in CT Groups

June 13, 2017

By Georg Mayer, 3GPP CT Chairman

The latest Plenary meeting of the Core Network and Terminals Technical Specification Group (CT TSG), held last week in West Palm Beach, Florida, has seen good progress in the Working Group’s study phase on 5G.

Existing & new protocols for the service based architecture (SBA), network slicing, Policy and Charging Control (PCC) as well as mobility and session management and many other features are currently under evaluation in a number of new 3GPP Technical Reports:

  • TR 24.890 - CT WG1 aspects of 5G System Phase 1
  • TR 29.890 - CT WG3 aspects of 5G System Phase 1
  • TR 29.891 - CT WG4 aspects of 5G System Phase 1
  • TR 31.890 - CT WG6 aspects of 5G System Phase 1

Besides that, the following, new, Release 15 Work Items were agreed. These are features that will immediately progress in to the normative phase:

IETF, 3GPP and 5G

June 7, 2017

The all new "Wednesday Speaker Club" took place today in West Palm Beach - during the 3GPP TSG Plenary meeting - with Alissa Cooper, the IETF Chair, sharing her views on how 3GPP and the IETF can cooperate on 5G.

Cooper told 3GPP delegates that important parts of the 5G work will span multiple SDOs and open source projects. She observed that IETF relationships with the IEEE, BBF, OPNFV and other bodies will be an area that will help broader collaboration, in addition to the potential for 3GPP and IETF to build on our well established cooperation on SIP/IMS and EAP-AKA work.

Georg Mayer, the 3GPP CT Chairman, introduced Ms Cooper as the first speaker in this new speaker club series. He set the scene for the presentation, telling delegates from the assembled 3GPP SA/CT and RAN (#76) plenaries that 3GPP - IETF cooperation has already made a major impact - particularly on protocol related topics.


Riding the NB-IoT bicycle

May 19, 2017

By Matthew Webb, 3GPP rapporteur on Enhancements of NB-IoT (NB_IOTenh).

Participants at the 3GPP RAN (WGs 1, 2, 3, 4, 5, 6) and the SA2 Working Group meetings, hosted by Huawei in Hangzhou this week, have joined a NB-IoT bicycle tour around Hangzhou’s beautiful West Lake.

modules 1000pxThe equipment used is an example NB-IoT use case being deployed in a cellular network in China, as part of a bicycle sharing service ‘ofo’. The bicycles are unlocked via a pin from a smartphone - by scanning a QR code on the bicycle. The pin code wakes up the NB-IoT module, which reports to the server then goes back to sleep until the user finishes the ride. When the customer locks the bicycle, the NB-IoT module re-activates to report the journey information and to generate a new pin for the next user. The NB-IoT module can also wake more often to provide other functions, such as periodic location reports.

By installing NB-IoT modules - which are pin-for-pin compatible with GPRS modules in the existing locks - power consumption is much improved, with the stand-by time extended by years, using the same battery.


3GPP Initiates Common API Framework Study

May 9, 2017
 
By Erik Guttman, 3GPP TSG SA Chairman
 
As we seek to provide standards for integration with a growing range of ‘vertical’ business sectors, 3GPP has initiated a new area of API specification work. 
 
At our March 2017 Plenary meeting (SA#75) a new Study on Common API Framework for 3GPP Northbound APIs was approved and now the SA6 Working Group – responsible for application layer functional elements and interfaces - has started investigating the topic. 

5G Communication for Automation in Vertical Domains

March 14, 2017

By Joachim W. Walewski, Siemens AG, rapporteur of the FS_CAV study item.

A new SA1 study item on requirements for automation in verticals focuses on critical communications as an enabler for wireless control loops. Once complete, the group will have identified the normative 3GPP work needed to deliver 5G for automation in a variety of industries.

The Study item description is in 3GPP SA Plenary document SP-170169.
