Non-3GPP Access Support

The non-3GPP access support of Open5GCore includes different levels of integration and trust on the wireless link.

Non-3GPP Access Support
Fraunhofer FOKUS

Support for untrusted non-3GPP access – tested with WiFi and LiFi

  • N3IWF – support for secure connectivity with the UE (NWu) and interconnection with the core network: N2 (NGAP), N3(GTP-U)
  • AMF - N1/N2 support for concurrent 3GPP and non-3GPP access
  • SMF - support for concurrent 3GPP and non-3GPP access
  • 5G UE simulation – N1 support for concurrent 3GPP and non-3GPP access, PDU session handover

Android UE – user space application enabling non-3GPP UE registration

Other support for non-3GPP accesses:

  • Over the top integration
    • tested with 60Ghz WiFi and Satellite
    • OTT connection with UE and the gNB simulation
  • Trusted non-3GPP access:
    • The UE is connecting to the TNGW without additional NWu security
