Architectural Highlights/Gaps: CU/DU split: the need for open interface F1 and functional split agreement CP/UP split: beyond current 3GPP standardization, but widely embraced by the operator community; heated discussion on open interface E1 and multi-vendor, RRM implementations in O-RAN, etc. Fronthaul: the fact that we have not been able to achieve FH testing in PoC phase is due to lack of well-established interface, but hopefully in PCNT. Performance Statements: We saw most of the performance KPI results are meeting with the PoC success criteria Some of the KPIs didn’t meet criteria, which was due to functionality or feature missing implementation or due to environmental constrains. We recommend these to be checked during pre-commercial trial phase.
This document aims to provide detailed updates on the functional split options for 5G and provide insight into how these splits might be deployed.
This document describes requirements for 5G Network and Service Management including Orchestration. The Document includes requirements covering all potential parts of future networks, i.e., fixed-, mobile-, cloud, virtualized technologies from a Network and Service Management including Orchestration perspective.
This whitepaper addresses the performance criteria of base station antennas, by making recommendations on standards for electrical and mechanical parameters, by providing guidance on measurement and calculation practices in performance validation and production, and by recommending methods for electronic data exchange. It also addresses recommendations on applying existing environmental and reliability standards to BSAs.
In a letter from the NGMN board members to the European Commission, NGMN reiterates its position to adopt a forward-thinking, technology-neutral approach in developing the EU’s C-ITS (Cooperative Intelligent Transport Systems) strategy. The letter, addressed to EC President Jean-Claude Juncker, calls upon European legislators to reconsider the current EC Draft Delegated Act in order to include cellular vehicle-to-everything (C-V2X) on the list of available/mature technologies that European stakeholders may utilise, therefore allowing the market to develop most effectively.
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 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 this convergence – including tighter integration of Wi-Fi access in 5G networks, network manageability and policy control, and the enablement of Wi-Fi-only devices.
This document (Version 2) focuses on the pre-commercial network trials phase of the NGMN 5G Trial & Testing Initiative which has the following scope: Developing a testing framework for 5G New Radio (NR), as developed by 3GPP, allowing the harmonization of the testing methodologies between the different parties conducting trials. Devising a strategy for the trials activities to guarantee efficiency and success of the different trials activities. Testing 5G capabilities in realistic conditions with pre-commercial equipment.
In a letter from the NGMN board members to the European Commission, NGMN strongly recommends to adopt a forward-thinking, technology-neutral approach in developing the EU’s C-ITS strategy. The letter, addressed to EC President Jean-Claude Juncker, calls upon European legislators to reconsider the current EC Delegated Act by including C-V2X on the list of potential technologies that European stakeholders may pursue and allow the market to decide which technology prevails. The board urges that given its importance, the Delegated Act adoption should not be rushed but conducted in transparent consultation with all stakeholders. A recent white paper on V2X technology published earlier this year by NGMN was also included, outlining the advantages of cellular technology over the less desirable wi-fi technology currently being considered.
5G network is expected to expose some of its capabilities to 3rd parties in order to catalyze the creative services based on them. The exposed network capabilities should thus create new business opportunities, but may also introduce new security risks. The security considerations depend on the exposure scenarios, the local regulation constraints, business models, and trust/liability models among the service user, the network capability provider (i.e., the network operator), and the network capability consumer (i.e., the 3rd party). The scope of this document is: To identify different network capabilities exposure scenarios; To investigate and propose security requirements for these scenarios; To investigate the exposure of security capabilities and present and evaluate the corresponding use cases. The main purpose of this document is: To help the network operators and their partners to find secure and beneficial ways of exposing the network capabilities; To influence the 5G-related standardization work in 3GPP (in particular, in SA3, SA1, SA2 and SA6) as well as in other SDOs.
This document focuses on the interoperability phase of the NGMN 5G Trial and Testing activities, where the main goal is to test interoperability of various equipment and interfaces in a realistic and heterogeneous environment and to provide feedback to the standardization body.
