5G takes its second wind towards the full global 5G standard, the commitment of the Verticals, and convincing demos by 5G PPP. The Winter Olympics and MWC’18 will likely see flourishing 5G trials and a number of interesting announcements.
2017 was very busy for both 5G PPP Phase 1 and Phase 2 projects. Some of the notable achievements include PoCs (Flex5Gware, Fantastic-5G, 5G-Crosshaul, 5G-Ex, Speed-5G, Coherent), METIS-II Visualisation Platform, 5G-ENSURE consultation on 5G security.
5GPPP Phase 2 projects leverage knowledge from various 5G PPP phase 1 projects including: SESAME for 5G ESSENCE, 5G-NORMA and METIS-II for 5G MoNArch, SONATA for 5G TANGO, COgNet, SELFNET and5GEx for SLICENET, Flex5GWare for MATILDA, 5G-XCast 5GCITY, 5G MEDIA and 5G TANGO,5G-ENSURE and CHARISMA for NRG-5, Superfluidity, VirtuWind, SONATA and SESAME for NGPaaS….

METIS-II Visualization Platform
In METIS-II, one of the key objectives was to enable the 5G concepts to reach and convince decision makers from non-ICT industries. Thus, it was necessary to have easy-to-understand illustrations of the envisioned 5G use cases and the proposed technical solutions, targeting the non-experts. A professional 3D visualization tool (METIS II Visualization Platform) enabling a viewer to interact with 5G enabled scenarios was introduced by METIS-II to achieve this and to allow the introduction of simulation driven data to be evaluated.

5G NORMA RAN design options
Three options for RAN slicing, namely slice-specific RAN, splice-specific radio bearer and slice-aware RAN, were presented by 5G-NORMA in July 2017 in its Deliverable D4.2 (https://5gnorma.5g-ppp.eu/wp-content/uploads/2017/12/5g_norma_d4-2.pdf):
Slice-specific RAN (Option 1), Slice-specific radio bearer (Option 2), Slice-aware shared RAN (Option 3).
• Option 1: Slice-specific RAN. The first option refers to the case where only transmission point specific functionality is shared among network slices while all other functionality is instantiated specifically for each network slice. In this case, the maximum degrees of freedom are achieved because each network slice may be customized down to the physical layer. On the other hand, this option requires a tight synchronization of the multi-tenancy policies applied to the common part and the per slice (dedicated) implementation, which may limit the achievable multiplexing gains considerably. Examples for this option include the possibility for implementing different radio access technologies within the same shared spectrum, e.g., 4G and 5G, or to separate two deployments while still
exploiting multiplexing gains.
• Option 2: Slice-specific radio bearer. The second option refers to sharing transmission point (cell) specific and user specific functionality, i.e., PHY and MAC in the data layer, and RRC in the control layer. This options slightly reduces the complexity because resource multiplexing would be implemented across all network slices and each network slice makes use of the same efficient flexible RAN implementation; on the other hand, each network slice may still customize the operation through configuration and parameterization based on the service requirements and each network slice may still implement its own QoS control (QoS prioritization). Hence, this option provides a reasonable trade-off of flexibility and complexity.
• Option 3: Slice-aware shared RAN. The third option in Figure 2-1 refers to a deployment where the complete RAN is shared by multiple tenants. This option is close to existing solutions such as eDECOR although in our case, multi-slice connectivity is considered. Hence, one UE may be connected to more than one network slice. In addition, the SMDC Coordinator is quite powerful in this option because a significant part of the RAN functionality may be implemented as applications on top of the SDM-X.
5G-ENSURE Open Consultation 2017: Key Findings
5G-ENSURE is driving a vision for 5G Security right from the first phase of the 5G PPP to identify challenges and priorities for security and privacy in Europe and beyond. Two open consultations have been published, one in 2016 and one in 2017, enabling key findings to feed into and complement the work being done in the 5G PPP Security WG.
The 2017 Open Consultation revolved around one key question: Security in 5G: where we stand today and what else needs to be done? The consultation was designed for representatives from 5G-related standardisation organisations, 5G industry (including SMEs), business verticals, policy makers and regulators, relevant industry associations and users of future communication networks.
Its main goals were to identify security aspects not yet addressed or only partially covered, barriers to progress on priority issues and how not tackling them in time might affect 5G adoption. The consultations have also been a driver for complementing industry perspectives on 5G security with views from other key stakeholders, such as policy makers, regulators and research.
Two main findings emerge from the 2017 Open Consultation:
– Many industry stakeholders (supply and demand) believe that security requirements for vertical industries are not yet fully understood. The main difficulties in defining the security of 5G network are mainly related to the different usage scenarios which imply different security requirements and consequently more flexibility in terms of security functionalities supported- The most challenging security issues are considered to come from IoT and network slicing.Looking at the overall picture emerging from the consultation, there is a general agreement on the following:
– The need for end-to-end security.
– There is consensus among industry and vertical representatives about several design principles emerging from the work in 5G PPP Security WG. Further debate and assessment would be a valuable contribution towards increasing consensus and/or possible other approaches.
– Inputs related to 5G PPP contributions are clearly only relevant to respondents familiar with the programme. However, those respondents involved in the programme believe that anticipating security issues and research results has helped to influence 5G standardisation to some extent. There is consensus that standardisation and compliance with standards is key to widespread adoption.
– Risks associated with innovative technologies point to possible delays in adoption. 5G is no exception. Similar viewpoints emerging from industry, verticals and 5G-related organisations. Increased exposure to cyber threats is also highly relevant. A key point emerging from the verticals is the lack of coherent regulations and policies for industry applications.
– Trust is another aspect of 5G that requires further investigation. Trust and liability model between the different stakeholders is the first step towards the widespread adoption of 5G, especially for vertical services. An emerging priority for regulatory bodies emerging from the survey is the introduction of new responsibility schemes in terms of distribution and allocation of responsibilities and obligations to address breach of Trust/ security between parties.
– One area for regulatory action is greater clarity on responsibilities and liabilities, as well as “access regulation”. In the context of 5G, regulators should seek to create and apply a consistent standard across the entire ecosystem so that the same criteria could be applied when evaluating the benefits and costs of open access mandates, regardless of sector or technology.

COHERENT use cases
The COHERENT 5G PPP phase 1 project comes to an end in March 2018. Three main use cases are considered to demonstrate the main achievements of COHERENT:
• RAN sharing: Intra-RAT radio resource management control app demonstrates the benefit of control plane programmability based on the COHERENT SDK to dynamically partition resources among multiple tenants/slices based on their service descriptor and their predicted short-term performance.
• Load balancing:
o Intra-RAT handover app demonstrates the benefit of data-plane programmability using the COHERENT SDK to trigger an X2 handover of a User Equipment (UE) based on the actual network conditions. Inter-RAT traffic steering app shows how the traffic of users can be dynamically steered, balanced, and isolated between Wi-Fi and LTE networks based on their actual radio resource
o Inter-RAT traffic steering app shows how the traffic of users can be dynamically steered, balanced, and isolated between Wi-Fi and LTE networks based on their actual radio resource utilizations.
• Spectrum management:
o Inter-RAT spectrum management app: demonstrates how the knowledge base maintaining the information related to operators and shared spectrums, policies, and interference are stored, managed and shared across different RAT, namely LTE and Wi-Fi.
o Intra-RAT spectrum sharing control app shows how the spectrum
information is retrieved and analyzed through the COHERENT SDK to find and reallocate the best available frequency, bandwidth, and power to a subset of cells that opportunistically make use of such spectrum to improve both users and network performance.
SELFNET will present in this workshop its network management framework, which provides three major benefits for 5G networks:
The SELFNET framework helps operators build a resilient network infrastructure for 5G, which makes the most effective use of the network technologies they already have.
The SELFNET framework enables service providers to significantly reduce the time for service creation, depending on the conditions down to about 10 minutes. The SELFNET framework can help network operators significantly reduce the total cost of ownership for their network infrastructures.
