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

[LUIS FELIPE RAMOS TORRES]

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
