5G Mobile Network Sharing Security V1.02

//in //by

Mobile network sharing could occur on different levels and with various sharing options in the mobile network infrastructure. Usually, these various sharing options require a thorough consideration of levels of protection. However, these levels of protection and security measures might affect the decision of selecting the types of sharing options. Vertical industries are facing a great challenge on selecting the suitable sharing option for their service and the adequate security for the particular mobile network infrastructure sharing option. This White Paper provides a reference for MNOs and vertical industries to identify the adequate security on each mobile network infrastructure sharing option.

NGMN 5G Devices SA Migration Scenarios

//in //by

To ensure the coexistence of 5G and 4G Devices, enabling the use of the new 5G Core Network, operators need to manage a transition period in which both 5G deployment architectures are present.

Taking a devices perspective, this white paper looks specifically at how Mobile Network Operators (MNOs) who currently operate 4G and 5G Non Standalone (NSA) networks can evolve to support 5G Standalone (SA) networks.

This paper presents a way to handle and optimize this transition. The goal is not only to guarantee an effective usage of the most valuable FDD and TDD Sub-6 bands (< 6GHz) but also effective usage of all frequency assets.

The re-farming strategies that can be implemented by Operators will inevitably be influenced by the speed of penetration of 5G Devices and the frequency bands that they support. Accordingly, a potential migration timeline has been defined.

NGMN CALLS FOR THE INDUSTRY TO SUPPORT UPLINK PERFORMANCE

//in , //by

Frankfurt, Germany, February 16, 2022: Verticals’ use cases need sufficient uplink throughput or cell capacity and low enough latency, when 5G Time-Division Duplex (TDD) bands are used to successfully realize their industrial use cases. The uplink performance is key to fully unlock the value of 5G. Therefore, the Next Generation Mobile Networks (NGMN) Alliance calls to increase efforts to enhance the uplink performance in its new White Paper “5G TDD UPLINK”. The Alliance formulates specific recommendations to regulators and other mobile industry stakeholders to support the ecosystem with adequate solutions. Also, various technical possibilities are presented – some of them are related to the management of interference, when differing frame structures are used to support the industries’ requirements.

Wolfgang Fleischer, Head of Network Innovation Technology & Business Evolution, A1 Group, NGMN Board Member and project lead, says: “Some of the applications for 5G technology, particularly in industrial settings, have greater requirements on the uplink – both in terms of capacity and shorter latency. This NGMN Initiative puts these into the spotlight and presents features to enable the networks to accommodate the requirements for such uplink dependent use cases.”

NGMN’s recommendations to better support the uplink throughput and latency requirements of Verticals include:

  • To use different TDD configurations
  • To select frame structure to vary uplink/downlink throughput
  • To carefully select more balanced or uplink oriented TDD frame structures in a local network
  • To consider the adoption of other uplink enhancing features such as SU-MIMO
  • To enhance 3GPP specification to fulfil requirements with respect to UL throughput, latency, and support for the co-existence of different frame structures by enhancements
  • To reserve spectrum for certain specific usages

The NGMN project will also reach out to chipset makers, regulators, Standard Developing Organisations and other involved parties to ensure that these NGMN recommendations are considered.-ends-

Further information and NGMN recommendations:

  1. A number of verticals’ use cases require significantly higher uplink throughput and lower latency than that required by typical Mobile Broadband consumer mobile users. There are solutions available to address this uplink problem (throughput and latency). Using different TDD configurations, as one of the solutions, requires coordination between operators in order to minimize possible interference and support by regulators to achieve sufficient operational flexibility to deliver customer use cases with higher uplink requirements.
  2. Frame structure selection is an effective way of varying uplink/downlink throughput. Additional balanced or uplink oriented frame structures should be made available and interoperable by ecosystem partners (chipset, user equipment and infrastructure providers). NGMN has identified specific slot formats, DDSUU (balanced) and DSUUU (uplink oriented), as candidates for specific frequency ranges (FR1 and FR2). Ecosystem partners should also support operators in making available and interoperable other possible alternative solutions identified in this White Paper to address this uplink problem.
  3. Careful selection of more balanced or uplink oriented TDD frame structures in a local network is recommended to limit the interference impact between local and wide-area public networks. However, if isolation between networks is sufficient (through physical separation, indoor with sufficient wall penetration loss, guard bands, etc.), the selection and use of TDD frame structures are less constrained and may be beneficial for services with a more balanced or uplink oriented traffic profile.
  4. In scenarios where sufficient isolation between networks is not achievable, e.g. local outdoor networks in the same or adjacent spectrum, using different TDD frame structures will be extremely difficult, if not impossible. In such cases, adoption of other uplink enhancing features such as SU-MIMO (Single-User Multiple Input Multiple Output) and MU-MIMO (Multi-User Multiple Input Multiple Output) should be considered.
  5. Future 3GPP specification enhancements, including 5G advanced and 6G, should ensure the requirements of verticals’ use cases are fulfilled with respect to UL throughput, latency, and support for the co-existence of different frame structures.
  6. Spectrum, particularly sub 6 GHz, is a critical and limited resource for mobile communications. Regulators need to carefully consider how it is assigned to ensure it can be used effectively and efficiently. Spectrum fragmentation due to reservation for certain specific usages could undermine the assignments of sufficiently large contiguous frequency blocks for 5G networks, potentially leading to under-utilization and spectrum inefficiency.
