This page is valid on the following branches:
- `master` starting from tag `v1.1.0`
- `develop` starting from tag `2019.w11`
# 1. Building the basic-simulator.
After the build simplification, the basic simulator is available directly from the standard build.
```bash
$ source oaienv
$ cd cmake_targets
$ ./build_oai --eNB --UE
```
Both eNB (lte-softmodem) and UE (lte-uesoftmodem) are present on `cmake_targets/ran_build/build` folder.
More details are available on the [build page](BUILD.md).
# 2. Running the basic simulator.
The basic simulator is a oai device replacing the radio heads (for example the USRP device). It allows connecting the oai UE and the oai eNodeB through a network interface carrying the time-domain samples, getting rid of over the air unpredictable perturbations.
This is the ideal tool to check signal processing algorithms and protocols implementation and having debug sessions without any HW radio equipment.
The main limitations are:
- A single OAI UE will connect to the OAI eNB
- No channel noise
## 2.1. Starting eNB
The basic simulator is able to run with a connected EPC or without any (the so-called "noS1" mode).
Example 1: running in FDD mode with EPC.
```bash
$ source oaienv
$ cd cmake_targets/ran_build/build
$ ENODEB=1 sudo -E ./lte-softmodem -O $OPENAIR_HOME/ci-scripts/conf_files/lte-fdd-basic-sim.conf --basicsim
```
Edit previously the `ci-scripts/conf_files/lte-fdd-basic-sim.conf` file to modify:
- `N_RB_DL` field to change the Bandwidth (25, 50, 100)
- `CI_MME_IP_ADDR` with the EPC IP address
- `CI_ENB_IP_ADDR` with the container (physical server, virtual machine, ...) on which you are executing the eNB soft-modem
Example 2: running in TDD mode without any EPC.
```bash
$ source oaienv
$ cd cmake_targets/ran_build/build
$ ENODEB=1 sudo -E ./lte-softmodem -O $OPENAIR_HOME/ci-scripts/conf_files/lte-tdd-basic-sim.conf --basicsim --noS1
```
## 2.2. Starting UE
Before starting the UE, you may need to edit the SIM parameters to adapt to your eNB configuration and HSS database.
The <conf> file to use for conf2uedate is `openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf`
You need to set the correct OPC, USIM_API_K, MSIN (this is the end par of the IMSI), HPLMN (the front part of IMSI) to match values from HSS.
```bash
$ source oaienv
# Edit openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf
$ cd cmake_targets/ran_build/build
$ ../../nas_sim_tools/build/conf2uedata -c $OPENAIR_HOME/openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf -o .
$ sudo -E ./lte-uesoftmodem -C 2625000000 -r 25 --ue-rxgain 140 --basicsim [--noS1]
```
The `-r 25` is to use if in the conf file of the eNB you use N_RB_DL=25. Use 50 if you have N_RB_DL=50 and 100 if you have N_RB_DL=100.
The `-C 2625000000` is the downlink frequency. Use the same value as `downlink_frequency` in the eNB configuration file.
The `--noS1` is mandatory if you started the eNB in that mode.
# 3. Testing the data plane
# 3.1. In S1 mode
First we need to retrieve the IP address allocated to the OAI UE.
On the server that runs the UE:
```bash
$ ifconfig oaitun_ue1
oaitun_ue1 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:192.172.0.2 P-t-P:192.172.0.2 Mask:255.255.255.0
...
```
`192.172.0.2` is the IP address that has been allocated by the SPGW in the EPC.
On the server that runs the EPC:
```bash
$ ping -c 20 192.172.0.2
--- 192.172.0.2 ping statistics ---
20 packets transmitted, 20 received, 0% packet loss, time 19020ms
rtt min/avg/max/mdev = 13.241/18.999/24.208/2.840 ms
```
You can ping the EPC from the UE:
```bash
$ ping -I oaitun_ue1 -c 20 192.172.0.1
--- 192.172.0.1 ping statistics ---
...
20 packets transmitted, 20 received, 0% packet loss, time 19019ms
rtt min/avg/max/mdev = 13.015/18.674/23.738/2.917 ms
```
For DL iperf testing:
On the server that runs the UE.
```bash
$ iperf -B 192.172.0.2 -u -s -i 1 -fm -p 5001
```
On the server that runs the EPC.
```bash
$ iperf -c 192.172.0.2 -u -t 30 -b 10M -i 1 -fm -B 192.172.0.1 -p 5001
```
For UL iperf testing:
On the server that runs the EPC.
```bash
$ iperf -B 192.172.0.1 -u -s -i 1 -fm -p 5001
```
On the server that runs the UE.
```bash
$ iperf -c 192.172.0.1 -u -t 30 -b 2M -i 1 -fm -B 192.172.0.2 -p 5001
```
# 3.2. In noS1 mode
The IP addresses are fixed. But we can still retrieve them programmatically.
For the UE it is quite the same:
```bash
$ ifconfig oaitun_ue1
oaitun_ue1 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:10.0.1.2 P-t-P:10.0.1.2 Mask:255.255.255.0
...
```
For the eNB:
```bash
$ ifconfig oaitun_enb1
oaitun_enb1 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:10.0.1.1 P-t-P:10.0.1.1 Mask:255.255.255.0
...
```
Pinging like this:
```bash
$ ping -I oaitun_ue1 -c 20 10.0.1.1
$ ping -I oaitun_enb1 -c 20 10.0.1.2
```
And the same for iperf:
```bash
$ iperf -B 10.0.1.2 -u -s -i 1 -fm
$ iperf -c 10.0.1.2 -u -b 1.00M -t 30 -i 1 -fm -B 10.0.1.1
```

After you have [built the softmodem executables](BUILD.md) you can set your default directory to the build directory `cmake_targets/ran_build/build/` and start testing some use cases. Below, the description of the different oai functionalities should help you choose the oai configuration that suits your need.
# Basic Simulator
See the [dedicated page](BASIC_SIM.md).
# RF Simulator
The rf simulator is a oai device replacing the radio heads (for example the USRP device). It allows connecting the oai UE (LTE or 5G) and respectively the oai eNodeB or gNodeB through a network interface carrying the time-domain samples, getting rid of over the air unpredictable perturbations. This is the ideal tool to check signal processing algorithms and protocols implementation. The rf simulator has some preliminary support for channel modeling.

This is sort of a "TCP driver" to ease debugging. This is mostly internal
to EURECOM. You probably don't want to use it.
Same license as the rest.
The driver tcp_bridge_oai.c is to be used with the basic simulator.
To build the basic simulator:
cd [openair top directory]
. oaienv
cd cmake_targets
./build_oai -I -w USRP
./build_oai --basic-simulator
cd ../common/utils/T/tracer
make
To use it, you need to run the eNB and the UE.
The eNB requires the T tracer.
Open two terminals.
In one terminal, run:
cd [openair top directory]
cd common/utils/T/tracer
./enb -d ../T_messages.txt
In the other terminal, run:
cd [openair top directory]
cd cmake_targets/basic_simulator/enb
export ENODEB=1
sudo -E ./lte-softmodem -O [configuration file] --T_stdout 0
[configuration file] is just a regular configuration file.
The eNB needs an EPC.
To run the UE, open a terminal and run:
cd [openair top directory]
cd cmake_targets/basic_simulator/ue
sudo ./lte-uesoftmodem -C 2680000000 -r 25 --ue-rxgain 140
Adapt the value of -r, it has to match the value N_RB_DL in the configuration
file of the eNB. (Same for -C which should match the value downlink_frequency
in the configuration file.)
The UE configuration (security keys) is generated from the file
openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf. You need to configure
your EPC to know about the UE. If you change the file
openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf then you need to
regenerate the configuration files using the program targets/bin/conf2uedata.
You run it as:
$OPENAIR_DIR/targets/bin/conf2uedata -c $OPENAIR_DIR/openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf -o $OPENAIR_DIR/cmake_targets/basic_simulator/ue

/* To startup proper communcation between eNB and UE,
we need to understand that:
- eNodeB starts reading subframe 0
- then eNodeB starts sending subframe 4
and then repeats read/write for each subframe.
The UE:
- reads 10 subframes at a time until it is synchronized
- then reads subframe n and writes subframe n+2
We also want to enforce that the subframe 0 is read
at the beginning of the UE RX buffer, not in the middle
of it.
So it means:
- for the eNodeB: let it run as in normal mode (as with a B210)
- for the UE, on its very first read:
- we want this read to get data from subframe 0
but the first write of eNodeB is subframe 4
so we first need to read and ignore 6 subframes
- the UE will start its TX only at the subframe 2
corresponding to the subframe 0 it just read,
so we need to write 12 subframes before anything
(the function tcp_bridge_read_ue takes care to
insert dummy TX data during the synch phase)
Here is a drawing of the beginning of things to make
this logic clearer.
We see that eNB starts RX at subframe 0, starts TX at subfram 4,
and that UE starts RX at subframe 10 and TX at subframe 12.
We understand that the UE has to transmit 12 empty
subframes for the eNodeB to start its processing.
And because the eNodeB starts its TX at subframe 4 and we
want the UE to start its RX at subframe 10, we need to
read and ignore 6 subframes in the UE.
-------------------------------------------------------------------------
eNB RX: | *0* | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 ...
-------------------------------------------------------------------------
-------------------------------------------------------------------------
eNB TX: | 0 | 1 | 2 | 3 | *4* | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 ...
-------------------------------------------------------------------------
-------------------------------------------------------------------------
UE RX: | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | *10* | 11 | 12 | 13 | 14 ...
-------------------------------------------------------------------------
-------------------------------------------------------------------------
UE TX: | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | *12* | 13 | 14 ...
-------------------------------------------------------------------------
As a final note, we do TX before RX to ensure that the eNB will
get some data and send us something so there is no deadlock
at the beginning of things. Hopefully the kernel buffers for
the sockets are big enough so that the first (big) TX can
return to user mode before the buffers are full. If this
is wrong in some environment, we will need to work by smaller
units of data at a time.
