Control and User Plane Separation of EPC nodes (CUPS)

July 03, 2017

At the recent CT#76 meeting (June 2017), 3GPP has completed the Release 14 specification of CUPS – set to be a key core network feature for many operators.

CUPS stands for Control and User Plane Separation of EPC nodes and provides the architecture enhancements for the separation of functionality in the Evolved Packet Core’s SGW, PGW and TDF. This enables flexible network deployment and operation, by distributed or centralized deployment and the independent scaling between control plane and user plane functions - while not affecting the functionality of the existing nodes subject to this split.

5G at RAN#76, a video interview

Video by Telecom TV, featuring Balazs Bertenyi, TSG RAN Chairman

A new video is on-line today, covering the transition from Rel-14 completion to the task of meeting two major milestones for Rel-15, within the next twelve months.

The video has news on the early drop of 5G NR specifications for December 2017 and some words on the full set of Rel-15 features - due by June 2018.

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.


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:

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.
