#### 0. Introduction
|
||||
|
||||
This tutorial introduces an install-and-run lab for Open5GS + Kamailio IMS
|
||||
VoLTE study, a follow-up project of [Open5GS Tutorial: VoLTE Setup with Kamailio IMS and Open5GS](https://open5gs.org/open5gs/docs/tutorial/02-VoLTE-setup/).
|
||||
The tutorial is based on Herle Supreeth's [docker_open5gs](https://github.com/herlesupreeth/docker_open5gs) and his fork of Open5GS and Kamailio.
|
||||
VoLTE study, a follow-up project of [Open5GS Tutorial: VoLTE Setup with Kamailio IMS and Open5GS](https://open5gs.org/open5gs/docs/tutorial/02-VoLTE-setup/).
|
||||
|
||||
The main purpose is to save researchers' and students' time to debug for a
|
||||
minimum-viable environment before actual study can be proceeded.
|
||||
|
||||
**Important notice before you start**
|
||||
|
||||
1. Herle Supreeth's fork of Kamailio is used to support IPsec.
|
||||
1. Java 7 is downloaded from an alternative location. You have to agree with
|
||||
Oracle's term of service and have an Oracle account, to legally use Java SDK
|
||||
7u80. By using this repo, I assume you have the legal right to use it and
|
||||
hold no liability.
|
||||
|
||||
You have to prepare IMSI, Ki, OP (yes, not **OPc**), SQN of your SIM cards.
|
||||
Even though Open5GS supports OPc, FHoSS merely takes OP. You may also want to
|
||||
disable SQN checking in the SIM card (even though we are not sure whether it is
|
||||
effective.) Check out https://github.com/herlesupreeth/sysmo-usim-tool for a
|
||||
slightly modified sysmo-usim-tool.
|
||||
|
||||
You have to prepare IMSI, Ki, OP/OPc, SQN of your SIM cards.
|
||||
|
||||
#### 1. Prepare SIM cards for VoLTE
|
||||
|
||||
**N.B.**
|
||||
1. Wrong KIC / KID / KIK bricks your SIM card.
|
||||
1. Use MCC = 001, MNC = 01 for a testing network, unless you know your MCC/MNC is supported by Android Carrier Privileges.
|
||||
2. Use MCC = 001, MNC = 01 for a test network, unless you know your MCC/MNC is supported by Android Carrier Privileges.

||||

||||

|
||||
* gp --acr-list
|
||||
|
||||
If you use gp.jar from Herle Supreeth's [CoSIM Wiki](https://github.com/herlesupreeth/CoIMS_Wiki), replace `gp --acr-list` with `gp --acr-list-aram`.

Clone the repository and build base docker images of open5gs and Kamailio:
|
||||
|
||||
```
|
||||
git clone https://github.com/miaoski/docker_open5gs
|
||||
git clone https://github.com/herlesupreeth/docker_open5gs

# Start MySQL and MongoDB first, in order to initialize the databases

|
||||

|
||||
```
|
||||
|
||||
You may want to review `.env` for IP allocation.
|
||||
#### 3. Configuring your setup
|
||||
|
||||
`.env` is the only file most of them need to edit as per their deployment needs
|
||||
{: .notice--warning}
|
||||
|
||||
#### 3. (Optional) Run srsENB in a separate container
|
||||
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
|
||||
```
|
||||
|
||||
If eNB is NOT running in the same docker network/host as the host running the dockerized Core + IMS then follow the below additional steps
|
||||
|
||||
Under `mme` section in docker compose file (`docker-compose.yaml`, `nsa-deploy.yaml`), uncomment the following part
|
||||
|
||||
```
|
||||
...
|
||||
# ports:
|
||||
# - "36412:36412/sctp"
|
||||
...
|
||||
```
|
||||
|
||||
Under `sgwu` section in docker compose file (`docker-compose.yaml`, `nsa-deploy.yaml`), uncomment the following part
|
||||
|
||||
```
|
||||
...
|
||||
# ports:
|
||||
# - "2152:2152/udp"
|
||||
...
|
||||
```

||||
#### 4. Building 4G/5G Core + IMS related components images
|
||||
|
||||
```
|
||||
cd docker_open5gs
|
||||
source .env
|
||||
docker-compose build --no-cache
|
||||
```
|
||||
|
||||
#### 5. (Optional) Run srsENB in a separate container
|
||||
|
||||
I use srsENB and USRP B210 in the lab. Sometimes you may want to restart
|
||||
srsENB while keeping the core network running. It is thus recommended to run
|
||||
srsENB separately.
|
||||
|
||||
Edit `.env` first to set EARFCN, TX_GAIN, RX_GAIN. Thereafter,
|
||||
|
||||
```
|
||||
cd docker_open5gs
|
||||
source .env
|
||||
docker-compose -f srsenb.yaml build --no-cache
|
||||
docker-compose -f srsenb.yaml up

||||

If there is a need to change the Core Network component configuration files

`docker-compose build` again.
