A- 5G-PPP Software Network WG releases ‘From Webscale to Telco, the Cloud Native Journey‘ white paper 2018

NGPaaS is chairing 5G-PPP Software Network WG. The WG released an important White Paper (WP) highlighting what we must do in order to design a cloud-native 5G system. The WP is available on the following Link.

Dr Bessem Sayadi, NGPaaS Project Coordinator at Nokia Bell Labs, argues:” We must ensure ascending compatibility with cloud environment in order to design a cloud-native 5G system and benefit from the best technologies from the cloud industry, essentially today the open source community, including micro-services, the de-facto cloud industrial standard, and more generally the service based architecture, and the most crucial technical assets from 5G-PPP Phase 1 and Phase 2 projects”.

B- 5G-PPP Software Network WG releases ‘Cloud-Native and Verticals’ services’ white paper 2019

  • As part of the 5G-PPP Initiative, the Software Network Working Group prepared this white paper as a follow-up of 2018 Cloud-Native transformation white paper to analyze how 5G-PPP projects interpret Cloud-Native design patterns and identify adoption barriers. The Software Network Working Group conducted a survey to collect technical inputs from 5G-PPP Phase 2 and Phase 3 projects on their:
    • supported vertical use-cases,
    • adopted virtualization technologies,
    • followed architecture patterns.
  • Results are two-fold:
    1. Projects are clustered according to their architecture patterns:
      1. Most project prototypes evolved from ETSI MANO relying on an Openstack VIM exclusively to include Kubernetes – on bare metal and public cloud – as a new VIM in parallel to Openstack.
      2. Meanwhile, they kept orchestration intelligence centralized in a VNFM-like box.
      3. Therefore, only a few of them fully exploited Kubernetes as a complete autonomous platform with its own orchestration intelligence able to host both Containerized Network Functions and classical VM-based VNFs.
    2. Analysis:
      1. We acknowledge a reluctance for using fully Cloud-Native design provided by e.g. Kubernetes. This reluctance has been analyzed to extract the underlying reasons motivating projects to select this intermediate step where Kubernetes is considered only as a VIM. These reasons are presented as the barriers to adopt the Cloud-Native patterns.
      2. These barriers are essentially the lack of standard and technological maturity,
        implying human adaptation resistance.

C- 5G-PPP Automotive WG:  White Paper ‘A study on 5G V2X Deployment‘ 2018

The WG released a white paper to MWC 2018 entitled: ‘A study on 5G V2X Deployment’. This paper provides first insights into the deployment models for 5G Vehicle to Anything (V2X). NGPaaS (via Nokia Bell-Labs France and Virtual Open Systems) contributed in Section 2 by describing the different stakeholders in the automotive business case and by proposing the vehicle as infrastructure business model described in section 2.2. Three business models in that area are described. A Press release from 5G-IA has been prepared for MWC 2018 related to the white paper release.

D- 5G-PPP Automotive WG:  White Paper ‘Business Feasibility Study for 5G V2X Deployment’ 2019

The key technology enablers for 5G Vehicleto-anything (V2X) communication are well studied and understood in the wireless industry, while standardization of 3GPP Rel. 16 V2X is in its final phase. Nevertheless, there is still some lack of insights into the required rollout conditions, roles of different stakeholders, investments, business models and expected profit from Connected and Automated Mobility (CAM) services. It is foreseen that these advanced CAM services, including high-definition (HD ) maps support, highway chauffeur, teleoperated driving, highly and ultimately fully autonomous driving, will be enabled through next-generation 5G vehicular networks, starting with 3GPP Rel. 16.

This second version of the white paper from the 5G PPP Automotive Working Group builds on the first one, which was published in early 2018 [1]. With respect to the first version, this paper includes further work and enhancements that targets the description of the 5G V2X ecosystem and stakeholder relationships, different sharing models for network infrastructure, as well as a business setup and finally a techno- economic assessment of the investment. The scope of the paper is to provide insights and trigger discussions on business models for CAM services, 5G V2X deployment costs and potential revenues. Available research studies, ongoing discussion within the 5G PPP, standardization bodies and other alliances are used as references to build the arguments in this paper.

The starting point is that, due to the technical requirements of CAM services, the deployment of a so-called 5G digitalized highway is a main enabler. The exemplary highway environment considered through this work includes 5G radio base station sites, civil work and fibre backhaul connections. It is further assumed that this investment could be used to a certain extent to provide enhanced Mobile Broadband (eMBB)
services in parallel to CAM services. The overall costs are standard-wise formed by CAPEX and OPEX including maintenance and service overhead.

The assumptions that have been made in the context of this white paper rely on working hypothesis and estimates aiming at identifying the most suitable investments model(s), but yet they should not prejudge the effective level of economic viability of the CAM business cases as it will result from market developments in the coming years.

This work aims at drawing the 5G CAM landscape of main stakeholders and relationships. Moreover, an investment and business model are proposed to describe the value flow between the involved actors. It shows under which conditions a return on investments for the 5G-digitalized highway can be expected, depending on investment costs, user fees and number of users. Moreover, a positive business case can be expected, especially when network infrastructure is shared between different operators. Particularly in the early phase of the 5G network deployment, synergies between the private and the public sector could speed up the deployment, allowing more users to get access to CAM services with lower charging rates and ultimately lead to much safer roads and efficient transportation.

 E- 5G-PPP Architecture WG:  5G Architecture White Paper Revision 2.0, 2019

The 5G Architecture Working Group as part of the 5G PPP Initiative is looking at capturing novel trends and key technological enablers for the realization of the 5G architecture. It also targets at presenting in a harmonized way the architectural concepts developed in various projects and initiatives (not limited to 5G PPP projects only) so as to provide a consolidated view on the technical directions for the architecture design in the 5G era.

The first version of the white paper was released in July 2016, which captured novel trends and key technological enablers for the realization of the 5G architecture vision along with harmonized architectural concepts from 5G PPP Phase 1 projects and initiatives. Capitalizing on the architectural vision and framework set by the first version of the white paper, the Version 2.0 of the white paper was released in January 2018 and presented the latest findings and analyses of 5G PPP Phase I projects along with the concept evaluations.

The work has continued with the 5G PPP Phase II and Phase III projects with special focus on understanding the requirements from vertical industries involved in the projects and then driving the required enhancements of the 5G Architecture able to meet their requirements. The results of the Working Group are now captured in this Version 3.0, which presents the consolidated European view on the architecture design.
