How to use

Automatic script

There is an automatic colosseum_srslte.py Python script in the /root/radio_api directory. The script allows to run eNB, EPC and UE nodes, and to start a Colosseum RF scenario. Please note that eNB and UE nodes are supposed to run on different SRNs of Colosseum.

usage: colosseum_srslte.py [-h] [--enb] [--epc] [--ue]
                           [--rf-scenario RF_SCENARIO]

optional arguments:
  -h, --help                   show this help message and exit
  --enb                        run eNB node
  --epc                        run EPC node
  --ue                         run UE node
  --rf-scenario RF_SCENARIO    RF scenario to start

Step-by-step instructions

Start Colosseum scenario

Select and start a Colosseum RF scanario, e.g., 1009. On any of the SRNs of the experiment run: colosseumcli rf start 1009 -c

The list of available scenarios can be consulted with: colosseumcli rf scenario list

Start LTE nodes

srsLTE configuration files are stored in radio_code/srslte_config

Run EPC and eNB on SRN 1:

• Run srsEPC in a first terminal window:
  • cd radio_code/srslte_config
  • srsepc epc.conf
• Run srsENB in a second terminal window:
  • cd radio_code/srslte_config
  • srsenb enb.conf

Run UE on SRN 2:

• Run srsUE in a terminal window:
  • cd radio_code/srslte_config
  • srsue ue.conf
