Catatan PLMN

• Internasional Test Network PLMN 001/01
• Internasional Private Network PLMN 999/99

5G Core

Modifikasi /etc/open5gs/amf.yaml untuk set NGAP IP address, PLMN ID, TAC dan NSSAI.

cd /usr/local/src/open5gs/install/etc/open5gs

kalau install dari binary cd ke folder

cd /etc/open5gs
cp amf.yaml amf.yaml.old
vi amf.yaml

Pastikan

amf:
    sbi:
      - addr: 127.0.0.5
        port: 7777
    ngap:
      #      - addr: 127.0.0.5
      - addr: 10.10.0.5
    metrics:
      - addr: 127.0.0.5
        port: 9090

          mcc: 001
          mnc: 01

          mnc: 01
        tac: 1

          mnc: 01

          - sst: 1
    security:
        integrity_order : [ NIA2, NIA1, NIA0 ]
        ciphering_order : [ NEA0, NEA1, NEA2 ]
    network_name:
        full: Open5GS
    amf_name: open5gs-amf0

Modify install/etc/open5gs/upf.yaml untuk set GTP-U dan PFCP IP address.

cd /usr/local/src/open5gs/install/etc/open5gs

kalau install dari binary cd ke folder

cd /etc/open5gs
cp upf.yaml upf.yaml.old
vi upf.yaml

Pastikan

upf:
    pfcp:
      - addr: 127.0.0.7
    gtpu:
      #      - addr: 127.0.0.7
      - addr: 10.11.0.7
    subnet:
      - addr: 10.45.0.1/16
      - addr: 2001:db8:cafe::1/48
    metrics:
      - addr: 127.0.0.7
        port: 9090

Restart Open5GS,

sudo systemctl restart open5gs-amfd
sudo systemctl restart open5gs-upfd

4G/ 5G NSA Core

Modify install/etc/open5gs/mme.yaml untuk set S1AP IP address, PLMN ID, dan TAC.

cd /usr/local/src/open5gs/install/etc/open5gs

kalau install dari binary cd ke folder

cd /etc/open5gs
cp mme.yaml mme.yaml.old
vi mme.yaml

Pastikan

mme:
    freeDiameter: /etc/freeDiameter/mme.conf
    s1ap:
      #      - addr: 127.0.0.2
      - addr: 10.10.0.2
    gtpc:
      - addr: 127.0.0.2
    metrics:
      - addr: 127.0.0.2
        port: 9090
    gummei:
      plmn_id:
        #        mcc: 999
        #        mnc: 70
        mcc: 001
        mnc: 01
      mme_gid: 2
      mme_code: 1
    tai:
      plmn_id:
        #        mcc: 999
        #        mnc: 70
        mcc: 001
        mnc: 01
      tac: 1
    security:
        integrity_order : [ EIA2, EIA1, EIA0 ]
        ciphering_order : [ EEA0, EEA1, EEA2 ]
    network_name:
        full: Open5GS

Modify install/etc/open5gs/sgwu.yaml untuk set GTP-U IP address.

cd /usr/local/src/open5gs/install/etc/open5gs

kalau install dari binary cd ke folder

cd /etc/open5gs
cp sgwu.yaml sgwu.yaml.old
vi sgwu.yaml

Pastikan,

sgwu:
    pfcp:
      - addr: 127.0.0.6
    gtpu:
      #      - addr: 127.0.0.6
      - addr: 10.11.0.6

Restart,

sudo systemctl restart open5gs-mmed
sudo systemctl restart open5gs-sgwud

Jika kita compile open5gs, kemungkinan script untuk systemctl belum ada. Ini akan menimbulkan ERROR.
