This page is valid on the following branches:
-
`develop`
starting from tag
`2020.w48`
# 1. Building the ITTI simulator.
The ITTI simulator is available directly from the standard build.
```
bash
$
source
oaienv
$
cd
cmake_targets
$
sudo
./build_oai
-x
-w
None
-c
?ittiSIM
```
# 2. Running the ITTI simulator.
The ITTI simulator establishes ITTI-threaded communication between the gNB RRC task and the UE RRC task.
This allows to test the sequence of NGAP/RRC/NAS messages.
The main limitations are:
-
NAS is a simple stub that just sends and receives messages
-
only initial Attach sequence
## 2.1. Starting the ITTI simulator
The ITTI simulator is able to run with a connected 5GC or without any.
The develop branch tag
`2020.w48`
only works RRC without 5GC connection.
```
bash
$
sudo
-E
./ran_build/build/nr-ittisim
-O
gnb.conf
```
