Konfigurasi
Untuk quick run (eNB/gNB, CN berada dalam docker network yang sama), edit hanya parameter berikut di .env sesuai setup kita
cd /usr/local/src/docker_open5gs vi .env
Parametery yang di ubah,
- MCC
 - MNC
 - TEST_NETWORK --> Ubah ini hanya jika bentrok dengan jaringan internal di rumah/kantor Anda
 - DOCKER_HOST_IP --> Ini adalah alamat IP dari host yang menjalankan pengaturan docker Anda
 - SGWU_ADVERTISE_IP --> Ubah ini ke nilai DOCKER_HOST_IP yang ditetapkan di atas hanya jika eNB tidak menjalankan jaringan/host docker yang sama
 - UPF_ADVERTISE_IP --> Ubah ini ke nilai DOCKER_HOST_IP yang ditetapkan di atas hanya jika gNB tidak menjalankan jaringan/host docker yang sama
 - UE_IPV4_INTERNET --> Ubah ini ke rentang ip jaringan UE yang Anda inginkan (agar tidak konflik) untuk APN internet
 - UE_IPV4_IMS --> Ubah ini ke rentang ip jaringan UE yang Anda inginkan (agar tidak konflik) untuk ims APN
 
Jika eNB/gNB TIDAK berjalan di jaringan/host docker yang sama dengan host yang menjalankan Core/IMS yang melakukan docker, ikuti langkah-langkah tambahan di bawah ini
Contoh .env
vi /usr/local/src/docker_open5gs/.env
MCC=001 MNC=01 TEST_NETWORK=172.22.0.0/24 DOCKER_HOST_IP=192.168.0.5 UE_IPV4_INTERNET=10.45.0.0/24 UE_IPV4_IMS=10.46.0.0/24 # SGW SGWC_IP=172.22.0.5 SGWU_IP=172.22.0.6 SGWU_ADVERTISE_IP=172.22.0.6 # SMF SMF_IP=172.22.0.7 SMF_DNS1=8.8.8.8 SMF_DNS2=8.8.4.4 # UPF UPF_IP=172.22.0.8 UPF_ADVERTISE_IP=172.22.0.8

4G deployment
Di bawah mme section di docker compose file (4g-volte-deploy.yaml), uncomment bagian berikut,
...
    # ports:
    #   - "36412:36412/sctp"

Provisioning SIM information
Provisioning SIM information di open5gs HSS sebagai berikut:
- Buka (http://<DOCKER_HOST_IP>:3000) di web browser, dimana <DOCKER_HOST_IP> adalah IP dari machine/VM yang menjalankan open5gs container. Login dengan credential berikut,
 
Username : admin Password : 1423
- Gunakan Web UI, tambahkan subscriber
 
Provisioning IMSI dan MSISDN dengan OsmoHLR sebagai berikut,
- Pertama-tama, login ke osmohlr container
 
docker exec -it osmohlr /bin/bash
- Kemudian, telnet ke localhost
 
telnet localhost 4258
OsmoHLR> enable OsmoHLR#
- Akhirnya, register subscriber information contoh berikut,
 
OsmoHLR# subscriber imsi 001010123456790 create OsmoHLR# subscriber imsi 001010123456790 update msisdn 9076543210
- Ganti IMSI dan MSISDN seperti SIM yang kita program.
 
Provisioning SIM information di pyHSS sebagai berikut,
- Akses http://172.22.0.18:8080/docs/
 - Pilih apn -> Create new APN -> Press Try it out. Kemudian, di payload section gunakan contoh JSON berikut dan tekan Execute
 
{
  "apn": "internet",
  "apn_ambr_dl": 0,
  "apn_ambr_ul": 0
}
- Catat apn_id yang di set di Response body dibawah Server response untuk internet APN
 - Ulangi creation step untuk payload berikut,
 
{
  "apn": "ims",
  "apn_ambr_dl": 0,
  "apn_ambr_ul": 0
}
- Catat apn_id yang di set di Response body dibawah Server response untuk ims APN
 - Execute this step of APN creation only once
 
Selanjutnya, select auc -> Create new AUC -> Press Try it out. Kemudian, di payload section gunakan contoh JSON berikut untuk mengisi ki, opc dan amf untuk SIM dan press Execute
{
  "ki": "8baf473f2f8fd09487cccbd7097c6862",
  "opc": "8E27B6AF0E692E750F32667A3B14605D",
  "amf": "8000",
  "sqn": 0,
  "imsi": "001010123456790"
}
- Catat auc_id yang di set di Response body dibawah Server response
 - Ganti imsi, ki, opc dan amf sesuai yang kita ingin program ke SIM
 
Selanjutnya, select subscriber -> Create new SUBSCRIBER -> Press Try it out. Selanjutnya, di payload section gunakan contoh JSON berikut untuk mengisi in imsi, auc_id dan apn_list untuk SIM dan press Execute
{
  "imsi": "001010123456790",
  "enabled": true,
  "auc_id": 1,
  "default_apn": 1,
  "apn_list": "0,1",
  "msisdn": "9076543210",
  "ue_ambr_dl": 0,
  "ue_ambr_ul": 0
}
- auc_id adalah ID untuk AUC dibuat di tahap sebelumnya.
 - default_apn adalah ID untuk internet APN dibuat di tahap sebelumnya
 - apn_list adalah comma separated list dari APN ID yang diijinkan untuk UE i.e. APN ID untuk internet dan ims APN dibuat di tahap sebelumnya
 - Ganti imsi dan msisdn sesuai dengan SIM yang kita program
 
Akhirnya, select ims_subscriber -> Create new IMS SUBSCRIBER -> Press Try it out. Selanjutnya, di payload section gunakan contoh JSON berikut untuk mengisi imsi, msisdn, msisdn_list, scscf_peer, scscf_realm dan scscf untuk SIM/deployment dan press Execute
{
    "imsi": "001010123456790",
    "msisdn": "9076543210",
    "sh_profile": "string",
    "scscf_peer": "scscf.ims.mnc001.mcc001.3gppnetwork.org",
    "msisdn_list": "[9076543210]",
    "ifc_path": "default_ifc.xml",
    "scscf": "sip:scscf.ims.mnc001.mcc001.3gppnetwork.org:6060",
    "scscf_realm": "ims.mnc001.mcc001.3gppnetwork.org"
}
- Ganti imsi, msisdn dan msisdn_list sesuai dengan SIM yang kita program.
 - Ganti scscf_peer, scscf dan scscf_realm seperti deployment kita
