docker_open5gs

Quite contrary to the name of the repository, this repository contains docker files to deploy an Over-The-Air (OTA) or RF simulated 4G/5G network using following projects:

Tested Setup

Docker host machine

  • Ubuntu 20.04 or 22.04

Over-The-Air setups:

  • srsRAN (eNB/gNB) using Ettus USRP B210
  • srsRAN eNB using LimeSDR Mini v1.3
  • srsRAN eNB using LimeSDR-USB

RF simulated setups:

  • srsRAN (gNB + UE) simulation over ZMQ
  • UERANSIM (gNB + UE) simulator

Building docker images

Clone repository and build base docker image of open5gs, kamailio, srsRAN_4G, srsRAN_Project, ueransim

# Build docker images for open5gs EPC/5GC components
git clone https://github.com/herlesupreeth/docker_open5gs
cd docker_open5gs/base
docker build --no-cache --force-rm -t docker_open5gs .

# Build docker images for kamailio IMS components
cd ../ims_base
docker build --no-cache --force-rm -t docker_kamailio .

# Build docker images for srsRAN_4G eNB + srsUE (4G+5G)
cd ../srslte
docker build --no-cache --force-rm -t docker_srslte .

# Build docker images for srsRAN_Project gNB
cd ../srsran
docker build --no-cache --force-rm -t docker_srsran .

# Build docker images for UERANSIM (gNB + UE)

Build docker images for additional components

cd ..
set -a
source .env
sudo ufw disable
sudo sysctl -w net.ipv4.ip_forward=1
sudo cpupower frequency-set -g performance

# For 4G deployment only
docker compose -f 4g-volte-deploy.yaml build

# For 5G deployment only
docker compose -f sa-deploy.yaml build

Network and deployment configuration

The setup can be mainly deployed in two ways:

  1. Single host setup where eNB/gNB and (EPC+IMS)/5GC are deployed on a single host machine
  2. Multi host setup where eNB/gNB is deployed on a separate host machine than (EPC+IMS)/5GC

Single Host setup configuration

Provisioning of SIM information

Provisioning of SIM information in open5gs HSS as follows:

Open (http://<DOCKER_HOST_IP>:9999) 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

or using cli

sudo docker exec -it hss misc/db/open5gs-dbctl add 001010123456790 8baf473f2f8fd09487cccbd7097c6862 8E27B6AF0E692E750F32667A3B14605D

Provisioning of IMSI and MSISDN with OsmoHLR as follows:

  1. First, login to the osmohlr container
docker exec -it osmohlr /bin/bash
  1. Then, telnet to localhost
$ telnet localhost 4258

OsmoHLR> enable
OsmoHLR#
  1. 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:

  1. Goto http://<DOCKER_HOST_IP>:8080/docs/
  2. 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

  1. 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

  1. 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": "1,2",
  "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

  1. 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
