OCUDU NTN

Experimental

This is an experimental blueprint intended for Non-Terrestrial Network (NTN) evaluation in an emulated environment.

This blueprint includes a fully emulated 5G Standalone (SA) Non-Terrestrial Network (NTN) using an OCUDU gNB connected to an Amarisoft NTN UE over the ZeroMQ, together with an Amarisoft 5GC and FlexRIC as the Near-RT RIC. A dedicated geo-simulator element emulates a GEO satellite channel. It operates in band n256 (5 MHz, 15 kHz SCS).

Use the command brc install network ocudu-ntn-amr-ue.yaml to deploy the network. It should finish without errors and print out the Kubernetes resource names that were created. Check for the status of the blueprint using the command brc observe. Wait until all the Elements other than the UE are in the STATUS set to 1/1 Y state.
