[srsran-users] An inquiry about srsRAN(Xiamen University, Xiamen, Fujian, China)

[Robert Falkenberg]

Hi Shaun,

from your screen-photographs I see that your UE successfully attached to 
the eNB.

The message shows, it got the IP address |172.16.0.2|.
You can check via |ip a| command, that after successful attach, there is 
a |tunX| network interface with that IP.
That network interface is like any other IP network interface of your 
PC, e.g. |ethX| for ethernet or |wlanX| for WiFi connections.

The computer that runs the EPC holds the IP address |172.16.0.1|.

Use these IP addresses to exchange data through that link, e.g. from the 
UE you can ping the EPC via |ping 172.16.0.1|; and from the EPC you can 
ping the UE via |ping 172.16.0.2|.

There are many ways to send a simple string from console through the 
network. For example you can use netcat |nc|:

First listen on EPC:

|nc -l -p 12345 |

Then send string from UE:

|echo "My message" | nc -c 172.16.0.1 12345 |

In the first terminal you will then see something like this:

|$ nc -l -p 12345 My message |

Best regards,
Robert
