Berbeda dengan nama repositorinya, repositori ini berisi file buruh docker untuk deploy jaringan 4G/5G simulasi Over-The-Air (OTA) atau RF menggunakan proyek berikut:

Test Setup

Docker host machine

  • Ubuntu 20.04 or 22.04

Over-The-Air (OTA) setup:

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

RF simulasi setup:

  • srsRAN (gNB + UE) simulasi menggunakan ZMQ
  • UERANSIM (gNB + UE) simulator


Persyaratan wajib: 

docker-ce - Version 22.0.5 atau yang lebih tinggi
docker-compose - Version 2.14 atau yang lebih tinggi


Setup IP Statik

Edit 

sudo su
apt update
apt -y install net-tools

vi /etc/netplan/00-installer-config.yaml

Pastikan, 

# This is the network config written by 'subiquity'
# network:
#   ethernets:
#     enp0s31f6:
#       dhcp4: true
#   version: 2
#

network:
    version: 2
    renderer: networkd
    ethernets:
        enp0s31f6:
            addresses:
                - 192.168.0.5/24
            nameservers:
                addresses: [8.8.8.8, 8.8.4.4]
            routes:
                - to: default
                  via: 192.168.0.222

Install

Clone repositori dan buat image docker dari open5gs, kamailio, ueransim 

cd /usr/local/src/
git clone https://github.com/herlesupreeth/docker_open5gs
cd docker_open5gs/base
docker build --no-cache --force-rm -t docker_open5gs .

cd ../ims_base
docker build --no-cache --force-rm -t docker_kamailio .

cd ../srslte
docker build --no-cache --force-rm -t docker_srslte .

cd ../srsran
docker build --no-cache --force-rm -t docker_srsran .

cd ../ueransim
docker build --no-cache --force-rm -t docker_ueransim .

Build dan Run menggunakan docker-compose 

cd ..
set -a
source .env
sudo ufw disable
docker-compose -f 4g-volte-deploy.yaml build
docker-compose -f sa-deploy.yaml build
sudo sysctl -w net.ipv4.ip_forward=1
sudo cpupower frequency-set -g performance

4G deployment 

# 4G Core Network + IMS + SMS over SGs
docker-compose -f 4g-volte-deploy.yaml up

# srsRAN eNB using SDR (OTA)
docker-compose -f srsenb.yaml up -d && docker container attach srsenb

# srsRAN ZMQ eNB (RF simulated)
docker-compose -f srsenb_zmq.yaml up -d && docker container attach srsenb_zmq

# srsRAN ZMQ 4G UE (RF simulated)
docker-compose -f srsue_zmq.yaml up -d && docker container attach srsue_zmq

5G SA deployment 

# 5G Core Network
docker-compose -f sa-deploy.yaml up

# srsRAN gNB using SDR (OTA)
docker-compose -f srsgnb.yaml up -d && docker container attach srsgnb

# srsRAN ZMQ gNB (RF simulated)
docker-compose -f srsgnb_zmq.yaml up -d && docker container attach srsgnb_zmq

# srsRAN ZMQ 5G UE (RF simulated)
docker-compose -f srsue_5g_zmq.yaml up -d && docker container attach srsue_5g_zmq

# UERANSIM gNB (RF simulated)
docker-compose -f nr-gnb.yaml up -d && docker container attach nr_gnb

# UERANSIM NR-UE (RF simulated)
docker-compose -f nr-ue.yaml up -d && docker container attach nr_ue

Konfigurasi

Untuk quick run (eNB/gNB, CN berada dalam docker network yang sama), edit hanya parameter berikut di .env sesuai setup kita

  • 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

4G deployment

Di bawah mme section di docker compose file (4g-volte-deploy.yaml), uncomment bagian berikut, 

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

Kemudian, uncomment bagian berikut di bawah sgwu section 

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

5G SA deployment

Di bawah amf section di docker compose file (sa-deploy.yaml), uncomment bagian berikut, 

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

Kemudian, uncomment bagian berikut dibawah upf section 

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

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,

  • 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
