AI-enhanced MANO

purpose: Automated deployment of a new services taking into account vertical requirements, QoS and QoE for every Network service running at the Greek site (under the 5G-EVE architecture)

5GTours implication:

AI-enhanced MANO can automate the deployment of a new critical service (e.g. Airport Evacuation use case) in a secure and robust way to achieve the use case specific requirements and optimize resource usage and services downtime due to network or general infrastructure problems. For the deployment of a new critical service the steps of AI-enhanced MANO are:

  • Critical service requests resources from MEC
  • Various metrics, KPIs and SLAs are gathered
  • AI-enhanced MANO algorithm decides and performs all deployments and migration actions

Localisation:

AI-Mano REST APIs using the OpenAPI V3 standard is located at: https://ai-mano.5gtours.wings-ict-solutions.dev/

Objective:

The specification includes:

  • Available endpoints (e.g. /kpis) and operations on each endpoint (e.g. GET /kpis, POST /kpis, DELETE /kpis, etc.)
  • Operation parameters Input (e.g. kpiID, Identifier of KPI)
  • Responses and output for each operation (with samples)
  • Schemas, description and example values
  • Authentication methods

Status:

Final version of API is available at the link: https://ai-mano.5gtours.wings-ict-solutions.dev/

Open Air Interface

OpenAirInterface Software Alliance (OSA) is an open-source alliance promoted and spearheaded by the French university and research institute Eurecom. Established in 2014, the OSA is non-profit organization (“Fonds De Dotation”), funded by corporate sponsors. The OSA is the home of OpenAirInterface, open software that gathers a community of developers from around the world, who work together to build wireless cellular Radio Access Network (RAN) and Core Network (CN) technologies. Openairinterface is a high-performance library for SDR applications, implemented in C and available under open source licenses. OpenAirinterface currently offers an SDR solution for LTE, which is quite alienated from the 3GPP standards. It is also actively working to achieve a stable version of New Radio Stand Alone (SA), as it currently offers a Non-Stand Alone (NSA) solution (support from the LTE network core).

The OAI code is available freely on Github, currently with many active branches. Within one of them, a stable version of FeMBMS is available (Branch ‘Develop’). The Further evolved multimedia broadcast multicast service (FeMBMS) is the LTE broadcast-only mode standardized in 3GPP Rel.14 where several modifications were made to enhance the system architecture and media formats flexibility for content providers, broadcasters, and mobile network operators.

5G-Tours implication:

Objective
  • To obtain an SDR receiver compliant with the 3GPP Release 16 specifications with:
    • At least one OFDM (Release 16) numerology.
    • CAS subframe with Release 16 improvements (New AL and PBCH Repetition).
  • To improve the synchronization mechanism and the stability.
  • To contribute with OAI (Branch Develop) with the final version of the code.
Status
  • 10/2021
    • New OFDM numerologies → Test phase (ongoing).
    • CAS subframe Release 16 → Test phase (completed).
    • Initial synchronization → Improved (completed).
    • Sync tracking → Debug phase (ongoing).
  • 07/2021
    • New OFDM numerologies → Debug phase.
    • CAS subframe Release 16 → Done (to be further tested).
    • Synchronization → Done (to be further tested).

Service Layer SDK descriptions

The 5G-TOURS Service Layer SDK is provided as an interface composed by a set of APIs exposed to the verticals. The consortium is currently producing 4 different APIs for the Service Layer, according to the specific targeted functionality and subject to partners’ policies:
