The role of 3GPP

3GPP is part of the invention, proof of concept, standardization, trials, commercialization …cycle

Its role is to specify and maintain a complete system description for mobile telecommunications

The system description is characterized by a number of standardized interfaces, not a description of standardized deployment

This standardization approach enables an interoperable, multi-vendor approach to deployment and generates mass market economies of scale, without stifling innovation

3GPP standards eco-system

Participation in 3GPP is made possible by companies and organizations becoming members of one of the 3GPP Organizational Partners, the seven Standards Developing Organizations (SDOs) - from China, Europe, India, Japan, Korea and the United States.

Specific inputs, in the form of market requirements may also come in to the Project via any of the 18 Market Representation Partners in 3GPP. These organizations have all signed up to the 3GPP Project scope and objectives.

There is also a lot of external cooperation with other standards bodies and a broad variety of other groups, by way of formal Liaisons.

3GPP Meetings

New work initiated by member companies via Work Items -outlining scope and time plan.

Work Items prioritised if all estimated work cannot be done by the scheduled release deadline.

All 3GPP member companies contribute on equal terms on any work item

3GPP seeks consensus on all technical matters (but has mechanisms if consensus cannot be reached)

Release deadline respected, unfinished work deferred to a later release

Stage 1 is an overall

service description from the

user’s standpoint.

Stage 2 is an overall

description of the organization

of the network functions to

map service requirements into

network capabilities.

Stage 3 is the definition of

switching and signalling

capabilities needed to support

services defined in stage 1.

A three-stage methodology as defined in ITU T Recommendation I.130 is applied in 3GPP according TR 21.900 clause 4.1

Work is completed in Releases of typically 15 – 18 months

New specifications issued at the completion of each release

Change requests then make corrections as needed

3GPP Work Plan

Release-based work• Releases are major packages of Features

• Work plan built using Work Items that deliver the Features

• Work Item Description exists for each of these • WI may cover more than one specification• WI may cover more than one TSG or WG• WI Description document exists for each WI

Multiple releases maintained in parallel

3GPP WorkPlan:• http://www.3gpp.org/Work-Plan

http://www.3gpp.org/Work-Plan

© 3GPP 2019


Maintaining multiple releases

Change Control

• Each release progressively frozen as it is developed

• Specifications pass under Change Control

• Rapporteur may no longer update drafts

• All changes managed by TSG

• Change Request process to introduce corrections/updates

• Package of CRs approved 4 times per year at TSG Plenary meeting

• CR database:

• CRs also searchable per specification via 3GPP website

• http://www.3gpp.org/specifications/change-requests

• CR process provides full traceability of all changes to every specification

Release and CR process closely related to market needs…see 5G example:

3GPP continues to expand the LTE platform to improve its efficiency to meet the mobile broadband demand

3GPP is on schedule with the standardization of 5G, addressing the expanded connectivity needs of the future

Phases for the normative 5G work• Phase 1 (Rel-15): Addresses the more urgent subset for commercial deployments

• Phase 2 (Rel-16): Completes the IMT 2020 submission, addresses all identified use cases & requirements

Where are we now on 5G?

What is 5G NR ?

Operation from low to very high bands: 0.4 –100Ghz

• Including standalone operation in unlicensed bands

Ultra wide bandwidth• Up to 100MHz in <6GHz

• Up to 400MHz in >6GHz

Set of different numerologies for optimal operation in different frequency ranges

System and Core Network Aspects

System Aspects include: Security, Media and Codecs, Operations and Management, Applications, Terminal and End to End Aspects, Interworking with External Networks

Core Network Aspects include: all functions to support for services provided by the 3GPP system.

• These categories are somewhat arbitrary. Some functions could be considered both Core Network and System Aspects.

Production

Enhancements for the system coming:• 5G LAN, High Precision Positioning, Cellular IoT for 5G, URLLC capabilities, Fixed and Satellite as 3GPP accesses,

ONAP interworking, QoS Monitoring, Network Automation, protocol and core network improvements…

5G will span several releases, look out for early Rel-17 studies*:• Asset Tracking Use Cases

• Communication Services for Critical Medical Applications

• enhancement for Unmanned Aerial Vehicles (UAVs)

• enhanced Relays for Energy efficiency and Extensive Coverage

• Network Controlled Interactive Services

• Audio-Visual Service Production* Many existing Rel-16 work items and studies will also mature in Rel-17

Conclusions

3GPP is industry driven

Standardization of interfaces enables an interoperable, multi-vendor approach to deployment

NR remains high focus for RAN groups

IMT-2020 ‘5G’ process progressing – 3GPP leading the way

Release 16 focus continues to expand towards new use cases and new sectors

The 3GPP processes are necessarily complex, but we need to adapt to bring new sectors in to the work

5G will be a multi-Release technology (beyond Release 16)
