[srsran-users] Connecting a COTS UE with srsRAN and LimeSDR

[sindi at innovatechtelecom.com]

Hi,

 

Did you masquerade the interface of your machine to the internet?

 

sudo /usr/local/bin/srsepc_if_masq.sh  <your interface>

 

Did you set the correct apn in your COTS UE?

 

Regards,

 

Sindi.

Dear community: 

 

I am trying to build an LTE network using srsRAN (epc and enb), and the LimeSDR device, but I have some issues. When I attach a COTS UE, it recognizes the network and it registers. But I have no access to the Internet, and also it is unstable. 

 

I am working on 1 machine, connected with USB 3 to LimeSDR. The machine is Ubuntu 22 with 16GB of RAM. I have some photos of the logs when I execute the commands. 

 

sudo srsenb enb.conf



 

sudo srsepc epc.conf



 



 

On UE: 

 



 

The UE can recognize the network. But when I surf on the Internet, it disconnects automatically. Maybe it is the firewall on the machine. Or the SDR device, or a configuration of the network. I am new to this, so if someone would help me, I would appreciate it a lot. 

 

Best wishes,

Luis Ramos
