Konfigurasi

For the quick run (eNB/gNB, CN in same docker network), edit only the following parameters in .env as per your setup

MCC
MNC
TEST_NETWORK --> Change this only if it clashes with the internal network at your home/office
DOCKER_HOST_IP --> This is the IP address of the host running your docker setup
SGWU_ADVERTISE_IP --> Change this to value of DOCKER_HOST_IP set above only if eNB is not running the same docker network/host
UPF_ADVERTISE_IP --> Change this to value of DOCKER_HOST_IP set above only if gNB is not running the same docker network/host
UE_IPV4_INTERNET --> Change this to your desired (Not conflicted) UE network ip range for internet APN
UE_IPV4_IMS --> Change this to your desired (Not conflicted) UE network ip range for ims APN

If eNB/gNB is NOT running in the same docker network/host as the host running the dockerized Core/IMS then follow the below additional steps

4G deployment Under mme section in docker compose file (4g-volte-deploy.yaml), uncomment the following part

...
    # ports:
    #   - "36412:36412/sctp"
...

Then, uncomment the following part under sgwu section

...
    # ports:
    #   - "2152:2152/udp"
...

5G SA deployment Under amf section in docker compose file (sa-deploy.yaml), uncomment the following part

...
    # ports:
    #   - "38412:38412/sctp"
...

Then, uncomment the following part under upf section

...
    # ports:
    #   - "2152:2152/udp"
...

Provisioning of SIM information Provisioning of SIM information in open5gs HSS as follows: Open (http://<DOCKER_HOST_IP>:3000) in a web browser, where <DOCKER_HOST_IP> is the IP of the machine/VM running the open5gs containers. Login with following credentials

Username : admin
Password : 1423

Using Web UI, add a subscriber

Provisioning of IMSI and MSISDN with OsmoHLR as follows: First, login to the osmohlr container docker exec -it osmohlr /bin/bash Then, telnet to localhost

$ telnet localhost 4258

OsmoHLR> enable
OsmoHLR#

Finally, register the subscriber information as in following example:

OsmoHLR# subscriber imsi 001010123456790 create
OsmoHLR# subscriber imsi 001010123456790 update msisdn 9076543210

Replace IMSI and MSISDN as per your programmed SIM

Provisioning of SIM information in pyHSS is as follows: Goto http://172.22.0.18:8080/docs/ Select apn -> Create new APN -> Press on Try it out. Then, in payload section use the below JSON and then press Execute

{
  "apn": "internet",
  "apn_ambr_dl": 0,
  "apn_ambr_ul": 0
}

Take note of apn_id specified in Response body under Server response for internet APN

Repeat creation step for following payload

{
  "apn": "ims",
  "apn_ambr_dl": 0,
  "apn_ambr_ul": 0
}

Take note of apn_id specified in Response body under Server response for ims APN

Execute this step of APN creation only once

Next, select auc -> Create new AUC -> Press on Try it out. Then, in payload section use the below example JSON to fill in ki, opc and amf for your SIM and then press Execute

{
  "ki": "8baf473f2f8fd09487cccbd7097c6862",
  "opc": "8E27B6AF0E692E750F32667A3B14605D",
  "amf": "8000",
  "sqn": 0,
  "imsi": "001010123456790"
}

Take note of auc_id specified in Response body under Server response

Replace imsi, ki, opc and amf as per your programmed SIM

Next, select subscriber -> Create new SUBSCRIBER -> Press on Try it out. Then, in payload section use the below example JSON to fill in imsi, auc_id and apn_list for your SIM and then 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 is the ID of the AUC created in the previous steps default_apn is the ID of the internet APN created in the previous steps apn_list is the comma separated list of APN IDs allowed for the UE i.e. APN ID for internet and ims APN created in the previous steps Replace imsi and msisdn as per your programmed SIM

Finally, select ims_subscriber -> Create new IMS SUBSCRIBER -> Press on Try it out. Then, in payload section use the below example JSON to fill in imsi, msisdn, msisdn_list, scscf_peer, scscf_realm and scscf for your SIM/deployment and then 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"
}

Replace imsi, msisdn and msisdn_list as per your programmed SIM

Replace scscf_peer, scscf and scscf_realm as per your deployment
