The Next Generation Mobile Networks (NGMN) Alliance is a mobile telecommunications association of mobile operators, vendors, manufacturers and research institutes. It was founded by major mobile operators in 2006 as an open forum to evaluate candidate technologies to develop a common view of solutions for the next evolution of wireless networks. Its objective is to ensure the successful commercial launch of future mobile broadband networks through a roadmap for technology and friendly user trials. Its office is in Frankfurt, Germany. [1]

Contents

The NGMN Alliance complements and supports standards organizations by providing a coherent view of what mobile operators require. The alliance's project results have been acknowledged by groups such as the 3rd Generation Partnership Project (3GPP), TeleManagement Forum (TM Forum) and the Institute of Electrical and Electronics Engineers (IEEE). [2] [3]

Activities

The Initial phase of the NGMN Alliance involved working groups on technology, spectrum, intellectual property rights (IPR), ecosystem, and trials, to enable the launch of commercial next generation mobile services in 2010. In a white paper first released in March 2006, NGMN summarized a vision for mobile broadband communications and included recommendations as well as requirements. It provided operators´ relative priorities of key system characteristics, system recommendations and detailed requirements for the standards for the next generation of mobile broadband networks, devices and services. [4]

From July 2007 to February 2008, standards and technologies were evaluated for next generation mobile networks. These were 3GPP Long Term Evolution (LTE) and its System Architecture Evolution (SAE), IEEE 802.16e (products known as WiMax), 802.20, and Ultra Mobile Broadband.

In June 2008, the NGMN Alliance announced that, “based on a thorough technology evaluation, the NGMN board concluded that LTE/SAE is the first technology which broadly meets its requirements as defined in the NGMN white paper. The NGMN Alliance therefore approves LTE/SAE as its first compliant technology”. [5] [6] [7] Also in June 2008 the alliance announced it would work with the Femto Forum to ensure femtocells benefit from the technology. [8] [9]

The alliance worked on intellectual property rights "to adapt the existing IPR regime to provide a better predictability of the IPR licenses (...) to ensure Fair, Reasonable And Non-Discriminatory (FRAND) IPR costs". [10] As part of this work, it issued a public request for information on LTE patent pool administration. [11] [12]

The alliance provided input to the International Telecommunication Union (ITU) World Radiocommunication Conference (WRC) on frequency allocation, since they considered a timely and globally aligned spectrum allocation policy a key to the development of a viable ecosystem on a national, regional and global scale. The ITU and regional bodies are developing channeling arrangements for the frequency bands identified at the ITU World Radio Conference in 2007. In October 2009, the NGMN spectrum working group released “Next Generation Mobile Networks Spectrum Requirements Update”, containing the status and NGMN views and requirements on frequency bands identified at the ITU WRC-07. [13]

Since next generation devices, networks and services need to be synchronized for a successful launch, NGMN in February 2009 released a white paper which provided generic definitions for next generation (data only) devices to ensure that devices were available at the time when first networks were launched in 2010. [14]

After the launch of the first LTE networks in 2010, [15] the alliance then addressed challenges of network deployment, operations, and interworking, while focusing on LTE and its evolved packet core, as defined by the System Architecture Evolution.

In September 2010, NGMN published recommendations on operational aspects of next generation networks. Rising complexity and increasing cost of network operations due to heterogeneity of networks (supporting different technologies), number of network elements, the market need to gain flexibility in service management and to improve service quality drive the need to improve the overall network operations. The document outlines requirements for self-organizing network functionalities and operations and maintenance (O&M) to address these issues. [16] [17]

In 2014, the NGMN Board decided to focus future NGMN activities on defining the end-to-end requirements for 5G. [18] [ circular reference ] A global team has developed the NGMN 5G White Paper [19] (published March 2015) delivering consolidated operator requirements to support the standardisation and development of 5G. NGMN encouraged the industry to have 5G solutions available by 2020, which was exceeded by some operators that already launched 5G trials in 2019. The commercial introduction of 5G naturally varied from operator to operator.

In 2015, NGMN launched a 5G-focused work-programme that built on and further evolved the White Paper guidelines. The main 5G NGMN work-items for 2015 were: the development of technical 5G requirements and architectural design principles, the analysis of potential 5G solutions and the assessment of future use-cases and business models. [20] Furthermore, the NGMN project teams addressed the areas IPR and Spectrum from a 5G perspective. In September 2015, the NGMN published a Q&A about 5G: [21]

In 2020, NGMN published an updated White Paper on 5G, requesting a common platform architecture to allow edge computing to be used on a global scale. Furthermore the NGMN Alliance positioned itself to provide a fully integrated solution for Verticals that encompasses networks, clouds and platforms, with dynamic customisation, partnerships, end-to-end management, carrier-grade security and efficient spectrum use. At the same time the organisation highlighted that an increased focus needs to be given to further improving energy efficiency, sustainability, social wellbeing, trust, and digital inclusion. [22] [23]

In October 2020, the NGMN Alliance launched a project on 6G [24] as well as a project on sustainability [25]

A new strategy was announced by the NGMN Alliance in February 2021, focusing on disaggregation, sustainability and 6G while still supporting the implementation of 5G’s full potential. [26] As a first outcome of that strategy, a project was launched to analyse the impact of disaggregation and cloudification on the operating model of mobile network operators and - in a pre-competitive environment - to develop operating model blueprints for enabling a successful E2E operation of disaggregated networks.

Organization

The NGMN Alliance is organized as an association of more than 80 partners from the mobile telecommunications industry and research. About one third are mobile operators, representing well over one half of the total mobile subscriber base world-wide. The remainder comprises vendors and manufacturers accounting for more than 90% of the global footprint of mobile network development as well as universities or non-industrial research institutes. [3] [27]

Cooperation

The NGMN Alliance co-operates with standards bodies and industry organisations like 3GPP, [28] the European Telecommunications Standards Institute, the GSM Association, and the TM Forum. [3] In July 2010, the alliance and the TM Forum agreed to work together on optimized management systems and operations of the next generation of mobile networks. [29] In May 2011 the alliance became a market representation partner to 3GPP.

In December 2014 ETSI and NGMN signed a cooperation agreement to intensify the dialogue and exchange of information between the two organizations. [30]

in June 2019, the EMEA Satellite Operators Associations (ESOA) and NGMN Alliance agreed to cooperate in the area of integration of satellite solutions in the 5G ecosystem. [31]

In October 2020, the NGMN Alliance and the O-RAN Alliance signed a cooperation agreement,cooperating in the area of Radio Access Network decomposition of 4G and 5G networks. [32]

In May 2021, the Linux Foundation and the NGMN Alliance signed a Memorandum of Understanding (MoU) for formal collaboration regarding end-to-end 5G and beyond. [33]

<span class="mw-page-title-main">Femtocell</span> Small, low-power cellular base station

In telecommunications, a femtocell is a small, low-power cellular base station, typically designed for use in a home or small business. A broader term which is more widespread in the industry is small cell, with femtocell as a subset. It connects to the service provider's network via broadband ; current designs typically support four to eight simultaneously active mobile phones in a residential setting depending on version number and femtocell hardware, and eight to sixteen mobile phones in enterprise settings. A femtocell allows service providers to extend service coverage indoors or at the cell edge, especially where access would otherwise be limited or unavailable. Although much attention is focused on WCDMA, the concept is applicable to all standards, including GSM, CDMA2000, TD-SCDMA, WiMAX and LTE solutions.

<span class="mw-page-title-main">Mobile broadband</span> Marketing term

Mobile broadband is the marketing term for wireless Internet access via mobile networks. Access to the network can be made through a portable modem, wireless modem, or a tablet/smartphone or other mobile device. The first wireless Internet access became available in 1991 as part of the second generation (2G) of mobile phone technology. Higher speeds became available in 2001 and 2006 as part of the third (3G) and fourth (4G) generations. In 2011, 90% of the world's population lived in areas with 2G coverage, while 45% lived in areas with 2G and 3G coverage. Mobile broadband uses the spectrum of 225 MHz to 3700 MHz.

<span class="mw-page-title-main">Evolved High Speed Packet Access</span> Technical standard

Evolved High Speed Packet Access, HSPA+, HSPA (Plus) or HSPAP, is a technical standard for wireless broadband telecommunication. It is the second phase of HSPA which has been introduced in 3GPP release 7 and being further improved in later 3GPP releases. HSPA+ can achieve data rates of up to 42.2 Mbit/s. It introduces antenna array technologies such as beamforming and multiple-input multiple-output communications (MIMO). Beam forming focuses the transmitted power of an antenna in a beam towards the user's direction. MIMO uses multiple antennas at the sending and receiving side. Further releases of the standard have introduced dual carrier operation, i.e. the simultaneous use of two 5 MHz carriers. HSPA+ is an evolution of HSPA that upgrades the existing 3G network and provides a method for telecom operators to migrate towards 4G speeds that are more comparable to the initially available speeds of newer LTE networks without deploying a new radio interface. HSPA+ should not be confused with LTE though, which uses an air interface based on orthogonal frequency-division modulation and multiple access.

The Global mobile Suppliers Association (GSA) is a not-for-profit industry organisation representing suppliers in the mobile communication industry. GSA actively promotes 3GPP technology such as 3G; 4G; 5G. GSA is a market representation partner in 3GPP and co-operates with organisations including COAI, ETSI, GSMA, ICU, ITU, European Conference of Postal and Telecommunications Administrations (CEPT-ECC), other regional regulatory bodies and other industry associations.

<span class="mw-page-title-main">LTE Advanced</span> Mobile communication standard

LTE Advanced (LTE+) is a mobile communication standard and a major enhancement of the Long Term Evolution (LTE) standard. It was formally submitted as a candidate 4G to ITU-T in late 2009 as meeting the requirements of the IMT-Advanced standard, and was standardized by the 3rd Generation Partnership Project (3GPP) in March 2011 as 3GPP Release 10.

<span class="mw-page-title-main">LTE (telecommunication)</span> Standard for wireless broadband communication for mobile devices

In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. Because LTE frequencies and bands differ from country to country, only multi-band phones can use LTE in all countries where it is supported.

A self-organizing network (SON) is an automation technology designed to make the planning, configuration, management, optimization and healing of mobile radio access networks simpler and faster. SON functionality and behavior has been defined and specified in generally accepted mobile industry recommendations produced by organizations such as 3GPP and the NGMN.

International Mobile Telecommunications-Advanced are the requirements issued by the ITU Radiocommunication Sector (ITU-R) of the International Telecommunication Union (ITU) in 2008 for what is marketed as 4G mobile phone and Internet access service.

<span class="mw-page-title-main">Small cell</span> Cellular network infrastructure

Small cells are low-powered cellular radio access nodes that operate in spectrum that have a range of 10 meters to a few kilometers. They are base stations with low power consumption and cheap cost. They can provide high data rates by being deployed densely to achieve high spatial spectrum efficiency.

The Asia-Pacific Telecommunity (APT) band plan is a type of segmentation of the 612–806 MHz band formalized by the APT in 2022–2023 and 2008-2010 respectively and specially configured for the deployment of mobile broadband technologies. This segmentation exists in two variants, FDD and TDD, that have been standardized by the 3rd Generation Partnership Project (3GPP) and recommended by the International Telecommunication Union (ITU) as segmentations A5 and A6, respectively. The APT band plan has been designed to enable the most efficient use of available spectrum. Therefore, this plan divides the band into contiguous blocks of frequencies that are as large as possible taking account of the need to avoid interference with services in other frequency bands. As the result, the TDD option includes 100 MHz of continuous spectrum, while the FDD option comprises two large blocks, one of 45 MHz for uplink transmission in the lower part of the band and the other also of 45 MHz for downlink transmission in the upper part. As defined in the standard, both FDD and TDD schemes for the 700 MHz band include guard bands of 5 MHz and 3 MHz at their lower and upper edges, respectively. The FDD version also includes a centre gap of 10 MHz. The guard bands serve the purpose of mitigating interference with adjacent bands while the FDD centre gap is required to avoid interference between uplink and downlink transmissions. The two arrangements are shown graphically in figures 1 and 2.

LTE in unlicensed spectrum is an extension of the Long-Term Evolution (LTE) wireless standard that allows cellular network operators to offload some of their data traffic by accessing the unlicensed 5 GHz frequency band. LTE-Unlicensed is a proposal, originally developed by Qualcomm, for the use of the 4G LTE radio communications technology in unlicensed spectrum, such as the 5 GHz band used by 802.11a and 802.11ac compliant Wi-Fi equipment. It would serve as an alternative to carrier-owned Wi-Fi hotspots. Currently, there are a number of variants of LTE operation in the unlicensed band, namely LTE-U, License Assisted Access (LAA), and MulteFire.

Citizens Broadband Radio Service (CBRS) is a 150 MHz wide broadcast band of the 3.5 GHz band in the United States. In 2017, the US Federal Communications Commission (FCC) completed a process which began in 2012 to establish rules for commercial use of this band, while reserving parts of the band for the US Federal Government to limit interference with US Navy radar systems and aircraft communications.

5G NR is a new radio access technology (RAT) developed by 3GPP for the 5G mobile network. It was designed to be the global standard for the air interface of 5G networks. As with 4G (LTE), it is based on OFDM.
