<br/>
This tutorial is an extension of a previous tutorial: [testing a `basic` deployment with dsTester](./DEPLOY_SA5G_BASIC_DS_TESTER_DEPLOYMENT.md). In previous tutorial, we have seen the advanced testing tool dsTester, which is useful for validating even more complex scenarios.
Moreover, there are various other opensource gnb/ue simulator tools that are available for SA5G test. In this tutorial, we use an opensource simulator tool called `UERANSIM`. With the help of `UERANSIM` tool, we can perform very basic SA5G test by simulating one gnb and multiple ues.
##### About UERANSIM -
[UERANSIM](https://github.com/aligungr/UERANSIM) is the open-source state-of-the-art 5G UE and RAN (gNodeB) implementation. It can be considered as a 5G mobile phone and a base station in basic terms. The project can be used for testing 5G Core Network and studying 5G System. UERANSIM can simulate multiple UEs and it also aims to simulate radio. Moreover for detailed feature set, please refer its [official page.](https://github.com/aligungr/UERANSIM/wiki/Feature-Set)
Let's begin !!
* Steps 1 to 5 are similar as previous [tutorial on vpp-upf](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-fed/-/blob/master/docs/DEPLOY_SA5G_WITH_VPP_UPF.md#5-deploying-oai-5g-core-network). Please follow these steps to deploy OAI 5G core network components.
* We deploy ueransim docker service on same host as of core network, so there is no need to create additional route as
we did for dsTest-host.
* Before we proceed further for end-to-end SA5G test, make sure you have healthy docker services for OAI cn5g
#### NOTE: ####
UERANSIM currently does not support integraty and ciphering algorithm NIA0, NEA0 repectively. Hence we have to update AMF config in the docker-compose as below -
##### IMPORTANT: Add following parameters in oai-amf service of docker-compose, before deploying core network.
```bash
- INT_ALGO_LIST=["NIA1" , "NIA2"]
- CIPH_ALGO_LIST=["NEA1" , "NEA2"]
```
Then we follow deployment procedure as usual.
```bash
oai-cn5g-fed/docker-compose$ docker-compose -f docker-compose-basic-vpp-nrf.yaml up -d
Creating mysql ... done
Creating oai-nrf ... done
Creating vpp-upf ... done
Creating oai-udr ... done
Creating oai-udm ... done
Creating oai-ext-dn ... done
Creating oai-ausf ... done
Creating oai-amf ... done
Creating oai-smf ... done
```
More details in [section 5 of the `basic` vpp tutorial](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-fed/-/blob/master/docs/DEPLOY_SA5G_WITH_VPP_UPF.md#5-deploying-oai-5g-core-network).
After deploying core network, make sure all services are healthy.
```bash
oai-cn5g-fed/docker-compose$ docker ps -a

```
## 6. Getting a `UERANSIM` docker image ##
You have the choice:
* Build `UERANSIM` docker image
```bash
$ git clone -b docker_support https://github.com/orion-belt/UERANSIM.git
$ cd UERANSIM
$ docker build --target ueransim --tag ueransim:latest -f docker/Dockerfile.ubuntu.18.04 .
```
OR
* You can pull a prebuilt docker image for `UERANSIM`
```bash
docker pull rohankharade/ueransim
docker image tag rohankharade/ueransim:latest ueransim:latest
```
## 7. Executing the `UERANSIM` Scenario ##
* The configuration parameters, are preconfigured in [docker-compose-basic-vpp-nrf.yaml](../docker-compose/docker-compose-basic-vpp-nrf.yaml) and [docker-compose.yaml OF UERANSIM](../docker-compose/docker-compose-ueransim-vpp.yaml) and one can modify it for test.
* Launch ueransim docker service
```bash
oai-cn5g-fed/docker-compose$ docker-compose -f docker-compose-ueransim-vpp.yaml up -d
Creating ueransim ... done
```
* After launching UERANSIM, make sure all services status are healthy -
```bash
oai-cn5g-fed/docker-compose$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
cb206b9b0a25 ueransim:latest "/ueransim/bin/entry…" 14 seconds ago Up 13 seconds (healthy) ueransim

```
We can verify it using UERANSIM container logs as below -
```bash
$ docker logs ueransim

Now we are ready to perform some traffic test.
* Ping test <br/>
Here we ping UE from external DN container.
```bash
$ docker exec -it oai-ext-dn ping -c 3 12.2.1.2

* Iperf test <br/>
Here we do iperf traffic test between UERANSIM UE and external DN node. We can make any node as iperf server/client.<br/>
Running iperf server on external DN container
