It looks like you already have a process listening on the addresses configured for the mme. Did you install via the quickstart guide, or build from source? If you installed via quickstart, the MME is already running, and is managed via systemd. You can see the status with |

Many thanks for your guidance. I used those commands and my MME was active and connected to HSS. |

Open5gs provides a 4G/5G cellular core network. In the cellular architecture the basestation is a piece of radio hardware distinct from the core network. If you are just hoping to experiment with 5G, you can use a simulated gNB and UE provided by https://github.com/aligungr/UERANSIM (see https://nickvsnetworking.com/my-first-5g-core-open5gs-and-ueransim/), but if you want to run a "real" network, you will need to acquire an eNodeB (for 4G) or a gNodeB (for 5G) separately. The UE is the "user equipment" and in most cases is a mobile phone or wifi hotspot. |

Hi @boukar10 You can set up each node on a separate VM as you described in 1st question. However, open5gs does not support OCS for billing purposes. Thanks a lot! |

No! Open5GS cannot connect to 3rd part OCS and does not have OCS/OFCS functionality. See also https://open5gs.org/open5gs/about/ Thanks! |

Hi Everyone,
after the configuration was done, I wanted to run the mme. So, I wrote the command $ ./install/bin/open5gs-mmed
Open5GS daemon v2.1.0 and I got these errors:
