This tutorial is a extension of previous tutorial. 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 are available for SA5G test. In this tutorial we use opensource simulator tool called gnbsim. With the help of gnbsim tool, we can perform very basic SA5G test by simulating one gnb and one ue.
* Steps 1 to 5 are similar as previous tutorial. Please follow these steps to deploy OAI 5G core network components.
* We depoloy gnbsim 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 procced further for end to end SA5G test, make sure you have healthy docker services for OAI cn5g -
```bash
oai-cn5g-fed/docker-compose$ docker ps -a

* The configuration parameters, are preconfigured in [docker-compose.yaml](../docker-compose/docker-compose.yaml) and [docker-compose-gnbsim.yaml](../docker-compose/docker-compose-gnbsim.yaml) and one can modify it for test.
