[srslte-users] srsEPC: UE unable to register on network

[Ignas Jarusevicius]

Hello All,

I am trying to set up srsENB and srsEPC with commercial UE. When UE
attempts to connect to the network, I get "UE Authentication Accepted"
message in srsEPC, but UE fails to register on the network. ENB and EPC
logs are attached.
UE registers successfully when srsENB is used with EPC from Amarisoft so
I think the problem is with srsEPC. Am I missing something in srsEPC
configuration or is it some limitation of srsEPC? Any help would be
appreciated.

Regards,
Ignas
