Dalam bahasa manusia, yang terjadi kira-kira sebagai berikut
- Core Network yang digunakan adalah Open5GS untuk simulasi sambungan 5G
- Pada 08:26:13.967 terlihat NF registerd, yang artinya sebuah gNB 5G berhasil connect ke Open5GS
- Pada 08:26:14.176 terlihat [imsi-510330000012345] Registration complete, yang artinya smartphone dengan IMSI 510330000012345 berhasil terdaftar
- Pada 08:26:14.177 terlihat [Added] Number of AMF-Sessions is now 1, yang artinya sudah dibuka sesi AMF untuk smartphone tersebut.

Di sisi gNB yang menjalankan UeranSIM, kita dapat membaca beberapa hal dari log, seperti,
- Pada jam 08:19:37.199 gNB berhasil connect ke Open5GS. IP address yang digunakan oleh UERANSIM adalah 192.168.100.238
- Pada jam 08:19:37.200 gNB meminta supaya Open5GS memberikan setup seperti MCC, MNC dll
- Pada jam 08:26:11.394 gNB mendeteksi adanya smartphone / UE yang ingin masuk
- Pada jam 08:26:13.895 gNB melakukan setup untuk smartphone untuk bisa tersambung dengan baik ke jaringan 5G

Di sisi virtual radio EURANSIM UE, kita bisa melihat proses terjadinya sambungan antara simulator smartphone UE dengan gNB. Dalam bahasa manusia kira-kira sebagai berikut,
- Pada jam 08:26:13.894 smartphone UE memilih jaringan yang menggunakan PLMN yang cocok dengan UE
- Pada jam 08:26:13.894 smartphone UE meminta untuk tersambung ke gNB
- Pada jam 08:26:13.895 smartphone UE berhasil tersambung
yang dilanjutkan dengan proses authentiasi dan konfigurasi hingga akhirnya sesi komunikasi dibuka antara smartphone yang kita gunakan dengan core network. Pada saat seluruh proses berhasil dilakukan, maka terakhir akan dibuat interface tunnel seperti yang terlihat
- Pada jam 08:26:14.185 interface tunnel TUN berhasil dibuka dengan baik
