OAI 5G CN Workshop Fall 2021 Overview
Fall 2021 OpenAirInterface Workshop focused on developing a 5G Core Network stack, featuring sessions on 5GC basic procedures, different 5GC modes, deployment strategies, and roadmap discussions. The workshop agenda included labs on deploying the OAI Core Network, using VPP-based UPF, network slicing, and Whitestack integration. Key sponsors and contributors included Qualcomm, Facebook (Meta) Connectivity, and EURECOM/OSA among others.

Fall 2021 OpenAirInterface Workshop: OAI 5G CN Session Tien Thinh NGUYEN, Sagar ARORA, Rohan KHARADE, Ismail MOHAMMED, Rapha l DEFOSSEUX
OAI 5G CN Project Group Website: https://openairinterface.org/oai-5g-core-network-project/ Develop a fully 3GPP compatible 5G CN stack (SA) as open source software for the OAI community Sponsors: Qualcomm, Facebook(Meta) Connectivity, InterDigital Main contributors: EURECOM/OSA, BUPT, KCL 2 Fall 2021 OAI Workshop
OAI 5G CN Current Status (1) A solid and functional 5GC Basic procedures (with multiple UEs/multiple PDU sessions): connection and registration procedures, session management procedures Additional features: NF registration, NF discovery (e.g., to discover and select SMF, UPF), N2 handover, Paging, HTTP/2, FQDN support Validation, CI/CD with Professional tester (dsTest, Developing Solutions): Testing AMF, SMF and UPF with simulated gNB/UE Bracket test for AMF, SMF (e.g., testing AMF with simulated SMF/UPF/gNB/UE) OAI gNB/ OAI UE, COTS UE (Quectel/ SIMcom modules), Amarisoft UEs Commercial gNBs (Amarisoft/Baicell)/ COTS UEs Open-source RAN simulators (gNBSim, UERANSIM) NF: Network Function, FQDN: Fully Qualified Domain Name 3 Fall 2021 OAI Workshop
OAI 5G CN Current Status (2) Different flavors Two 5GC modes Minimalist 5GC with AMF, SMF, NRF and UPF Basic 5GC with AMF, SMF, NRF, UPF, UDM, AUSFandUDR Three UPF flavors: SPGW-U (from 4G) with additional features for 5G VPP-UPF (relying on VPP- Travelping, with DPDK support) Production grade UPF (Kaloom, on-going) Deployment, CI/CD Traditional/classic deployment on Servers/Virtual machines Automated deployment of NFs in Docker containers using Docker-Compose Cloud-native deployment using Helm Chart (on OpenShift cluster) DPDK: Data Plane Development Kit VPP: Vector Packet Processing 4 Fall 2021 OAI Workshop
OAI 5G CN Roadmap 5 Fall 2021 OAI Workshop
OAI CN Session - Agenda Lab 1: How to deploy OAI Core Network (Sagar) Lab 2: How to use VPP-based UPF instead of SPGW-U (Rohan) Lab 3: Network Slicing with OAI 5G Core Network (Thinh) Whitestack: How Whitestack is using OAI stack? (Gabriel/Sergio) Challenge (Rapha l) 6 Fall 2021 OAI Workshop
