[srslte-users] Received UE Context Release - UE Losses Internet

[Ron]

Hi All,

We had encountered an issue after registration. The UE successfully register to the network,  but after 10 seconds, the internet will then be unreachable. We also tried to ping the srs_spgw_sgi and it becomes unreachable. But as per checking the “ifconfig”, the srs_spgw_sgi is still present.

We also tried to reconnect the UE to the network and it will again access the internet within the first 10 seconds and then the internet will cut off. In the EPC logs, it shows “Received UE Context Release Request. MME-UE S1AP Id 1”.

We are using Ubuntu 16.04:

# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release:  16.04
Codename:  xenial

We are also using B210 as our SDR an Intel NUC for the server.

Attached are the config files, logs and traces used during the testing.

Best Regard,

Ron Menez
