End-to-End LTE Tests
|
||
|
|
====================
|
||
|
|
|
||
|
|
This folder contains a basic shell script that allows a quick end-to-end LTE test
|
||
|
|
using srsUE, srsENB, and srsEPC. The script has minimal requirements and should
|
||
|
|
only take less then 30 seconds for each configuration. Currently the script
|
||
|
|
only allows to configure the cell bandwidth.
|
||
|
|
|
||
|
|
The script launches all components and puts the UE into a different network namespace
|
||
|
|
in order to allow IP connectivity to srsEPC on a single machine. It therefore
|
||
|
|
requires root privelages at the moment.
|
||
|
|
|
||
|
|
It then launches, one after another, uplink and downlink ping as well as a quick UDP
|
||
|
|
downlink session. Between those experiments, the UE transits between RRC Idle and Connected
|
||
|
|
states multiple times and is either put into Connected through pending UL traffic or
|
||
|
|
pending DL traffic (using paging).
|
||
|
|
|
||
|
|
After the experiments are finished, all components are torn down and the log files
|
||
|
|
are analyzed.
|
||
|
|
|
||
|
|
|
||
|
|
Single Execution
|
||
|
|
----------------
|
||
|
|
|
||
|
|
The script can be executed manually. It expects the srsLTE build directory as
|
||
|
|
the first argument and the cell bandwidth as the second.
|
||
|
|
|
||
|
|
```
|
||
|
|
$ sudo ./run_lte.sh ~/src/srsLTE/build 50
|
||
|
|
```
|
||
|
|
|
||
|
|
Testing all Bandwidths
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
You can also test all bandwidths by letting CTest iterate over all possible PRB sizes.
|
||
|
|
|
||
|
|
```
|
||
|
|
$ cd test
|
||
|
|
$ sudo make test
|
||
|
|
```
|
||
|
|
|
||
|
|
Known Issues
|
||
|
|
------------
|
||
|
|
|
||
|
|
If you've started the script and it failed it may left the network namespace open and thus
|
||
|
|
the next execution of the script will fail. In this case, just delete the network namespace
|
||
|
|
before running again:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ sudo ip netns delete ue1
|
||
|
|
```
