HS meeting 07-10-2021

Health5G

1. Agenda

die folgende Agenda erstellt:

  • Begrüßung und Einleitung (Alfons Mittermaier)
  • Überblick über Network Slicing in der O-RAN Alliance (Martin Skorupski)
  • Intent-based NBI (Shabnam Sultana)
  • Network Slicing in ONAP (Alexander Dehn)
  • Network Slicing im RAN (Martin Kasparick HHI)
  • Network Slicing mit dem Nokia gNB am HHI (Mathias Hänsel)
  • Unterstützung durch den O1-Mediator (Ingo Bauer oder Brahim Ambari)

2. Overview

  • O-RAN WG1
  • ORAN-SC implement ORan Alliance specs
  • MEF transport slicing
  • 5G super blueprint

3. Intent based

  • Service oriented mgmt 3GPP SA5
  • BSS/intent –> CSMF –> NSMF –> NSSMF
  • CSMF: up/down link, geo area
  • Standard for intent translation? at least policy and configuration description.
    • 3GPP TS 28.312, R 28.812
    • IETF IBN Definition
    • ETSI ENI 005: Architection
  • Challenges:
    • realtime network monitoring
    • logical verification
    • no common API, standard.
  • ONAP
    • IBN sub component

4. ONAP slicing

  • implemented CSMF, NSMF, NSSMF
  • NSI LCM: creation, activation, etc.. 3gpp 28.530
  • WIP: slice creation UI, LCM.
  • slice template definition?

5. RAN slicing

  • RAN slice config: l1, l2, scheduling
  • potential design params
    • available antenna RUS, RRHs
    • virtualized RAN RU, DU, CU, RRH
    • Bandwidth: prequencies, freq. bands
    • TX power,
    • beams
    • Subcarrier spacing, no. of HARQ process.
  • MAC RRM, PHY, access control.

6. Nokia RAN (micronova)

  • QoS profile for each slice. Scheduler allocates resources.
