IPR Forum

NGMN paves the way for the development of 5G patent licensing practices across industry segments

The Next Generation Mobile Networks (NGMN) Alliance has jointly organised and executed a successful conference on Licensing Practices in 5G Industry Segments with the International Telecommunication Union (ITU), bringing various experts from around the world together to discuss licensing practices and challenges of 5G.


Geneva, Switzerland – The conference featured moderators and speakers from some of the biggest names in telecoms, including AT&T, Deutsche Telekom, NTT DOCOMO, Orange, Ericsson, Nokia and Microsoft. Also in attendance were key stakeholders of vertical industries, including Audi, Bosch, Panasonic and u-Blox, and patent pool administrators, namely Avanci, MPEG-LA, Sisvel and Via Licensing, who co-sponsored the event, the European Telecommunications Standards Institute (ETSI), the Japanese and the European Patent Offices, and the European Commission. Focusing on the development of 5G and the Internet of Things (IoT), the conference facilitated sharing and discussing of present-day licensing practices and related issues across different industry segments.A host of insightful sessions took place igniting an inclusive exchange on:

  • Patent licensing practices with interactive discussions that focused on issues stakeholders need to be aware of.
  • Sharing licensors’, licensees’ and pool administrators’ requirements on patent pools/platforms.
  • Identifying proposed practices and conducts for licensors and licensees.
  • Listing requirements for increasing transparency and assessing essentiality of Standard Essential Patents declared to Standards Developing Organisations.


“It’s great to notice that our joint ITU-NGMN conference has been such a success,” said Dr. Peter Meissner, CEO of NGMN. “Obviously, the 5G Eco-System is different. New use cases beyond mobile broadband – like massive IoT as well as highly demanding requirements from vertical industries on low latency, ultra-high reliability and security – are causing substantial network transformations. All these challenges have implications on the intellectual property of mobile network operators and across the different industry segments. Conferences like this are key in identifying IPR issues and exploring solutions for the enlarged eco-system.”


On a related matter, NGMN will be hosting a Press & Industry Briefing on 5G use cases beyond mobile broadband on 26th February 2019, from 11am – noon at Mobile World Congress in Barcelona, Spain. If you are interested in attending or speaking to an NGMN representative, please contact ngmn(at)


NGMN & Wireless Broadband Alliance join forces to address RAN convergence opportunities

Call for combined 5G and Wi-Fi network resources to address opportunities and use casesLondon, Frankfurt – NGMN and Wireless Broadband Alliance (WBA) have published the first results of their collaboration to drive the convergence of multi-technology RANs and core networks. The joint report identifies a number of emerging opportunities and use cases that the industry can benefit from through the convergence of 3GPP’s 5G and Wi-Fi, driven by the ever-enhancing capabilities of licenced and unlicensed technologies. It also highlights the key challenges, which must first be addressed in order to realise convergence over 3GPP Access and Wi-Fi – including tighter integration of Wi-Fi access in 5G networks, network manageability and policy control, and the enablement of Wi-Fi-only devices.

The convergence opportunity
Wi-Fi and cellular ecosystems have traditionally followed their own development paths. The latest versions of each technology have greatly enhanced capability compared with early offerings, with Wi-Fi 6 and 3GPP’s 5G, encompassing New Radio (NR) and LTE from Release 15 onwards, as well as the 3GPP 5G Core. However, as society increasingly depends on fast reliable data connectivity, NGMN and WBA believe an important capability for the industry is the convergence at a network level between 5G and Wi-Fi, so that the unique and complementary capabilities of both RANs can be leveraged to provide seamless network services. Bearing in mind that a significant amount of data traffic from smartphones use a Wi-Fi access, this will lead to a better user experience and create new business opportunities for both Wi-Fi and cellular providers.

New resource requirements
The report identifies a number of use cases and verticals that may require combined resources from both 5G and Wi-Fi networks in providing cost effective solutions that meet diverse sets of requirements on throughput, latency, connection density, coverage, availability and reliability. For example, enterprise services on cellular networks, and in particular, those that the 5G Core enables, may require a new look at the use of an access neutral mechanism for a number of reasons. These include gaps in coverage, the proliferation of indoor and outdoor Wi-Fi deployments, and potential for multi-site enterprise environments.
“Convergence of 5G and Wi-Fi can potentially bring major benefits to cellular operators, enterprise Wi-Fi and public Wi-Fi solution providers, giving access to 5G and enterprise services from both Wi-Fi and 5G access networks.” said Dr. Peter Meissner, CEO of the NGMN Alliance. “However, in order to realise service and network convergence, we have worked with the WBA to identify a number of requirements that must first be satisfied. This is particularly true in the enterprise and Public Wi-Fi space, where there is a demand from cellular operators for a standardised solution for improved visibility and control in the configuration and management of Wi-Fi access networks.”

5G/Wi-Fi Interworking
A number of industry developments and specifications address the interworking of 5G and Wi-Fi from a technical standpoint:

  • 3GPP has already developed specifications to ensure tight integration of 3GPP and non-3GPP radio technologies, such as Wi-Fi. In order to better serve customers and provide the full 5G experience the tight integration of non-3GPP technologies needs to be ensured also within the 5G Core Network. Solutions enabling some of these objectives have already been adopted by 3GPP and Wi-Fi 6, such as the EAP authentication framework similar to Wi-Fi, to accommodate different wireless service subscription-types (e.g. mobile, wireless or fixed broadband) and their native authentication methods.
  • 3GPP Release 15 provides some support for interworking between 5G and Wi-Fi. In particular, 3GPP Release 15 provides support for untrusted non-3GPP access (such as Wi-Fi) to the 5G core via Non-3GPP Interworking Function (N3IWF), with secure transport of Control-Plane/User-Plane (CP/UP) messages over an IKEv2/IPSec tunnels between the terminal devices and the N3IWF.
  • 3GPP Release 16 is continuing the work by enhancing capabilities for Wi-Fi integration, including trusted Wi-Fi support and access traffic steering, switching and splitting.

However, challenges and needs remain – including the enablement of Wi-Fi only devices to connect to the 5G core, further study to ensure the tight integration between 5G and Wi-Fi networks, an interface to enable certain level of network manageability and policy control between 5G core and Wi-Fi networks, and the ability of a client to route traffic over one or more accesses, making optimal use of the available connectivity. As a next step, the WBA and NGMN are undergoing further study on these challenges in order to uncover potential solutions. This will culminate in the recommendation of a future strategy for Converged RAN deployment, ensuring the best user experience making use of both Wi-Fi and Cellular access.

Tiago Rodrigues, General Manager of WBA said: “Wi-Fi 6 introduces new capabilities for carriers, cities and enterprises to cost effectively provide additional coverage and capacity, mainly indoor, to address the 5G use case requirements. Now it’s time to fully capitalize on these capabilities by delivering a clear strategic path for converged RAN deployments. This is a priority. We will continue to work closely with NGMN and its members to review, develop and test potential solutions, as identified in our recent 5G White Paper.”
