RAN-5GC Timings

What we want to achieve in the page is to measure and benchmark the time it takes to deploy a Trial Netowrk involving a physical gNB and a virtual 5G Core in different sites.

ran-5gc-overview

The target values to measure are:

  • SrvPT or Service Provisioning Time: Time taken to provision the entire Trial Network, including RAN and 5GC components.
  • SlcPT or Slice Provisioning Time: Time taken since the slice is created in the 5GC, and a connection to the gNB is established.
  • NGRT or NGAP Restoration Time: Time taken to restore the NGAP connection between gNB and 5GC after a disruption (e.g., restarting the 5GC or network issues).

Results​

Site UMA​

The experiments were conducted at the UMA site using component open5gs_k8s over oneKE with a private vnet, and component nokia_radio.
