[srslte-users] srsenb disconnection problem

[Nicola Bui]

Dear all,

I am running srsenb using oai as EPC. My mobile phone (moto g5+) connects
to the network and for a while behave normally (ping is ok, surfing is ok,
speedtest is fine). However, after some time everything stops working even
though the phone still has an IP address the enb says the UE is attached
(c-RNTI assigned properly).
Actually, in the enb log I can see the c-RNTI got released and a new one
got assigned to the UE, but the new connection is not working anymore. The
only way for recovering the connectivity is from the mobile toggling on and
off the airplane mode.
The only error message I can see is: Unhandled feature in RRC function:
liblte_rrc_unpck_rrc_connection_setup_complete
However this appears even when the connection has been properly setup.

It will be great if I can get a more stable connection or if the connection
can be automatically reestablished.
Any suggestion on how to debug this?

Thanks,
