[srsran-users] There is no Attach Reject

[Mania Mania]

Hi,
I have implemented an LTE network using srsRAN + open5gs and
USRP-B210(without GPSDO).
I tried to connect a commercial phone (Samsung galaxy note3) to the network
and see the UE's captured packets using QCSuper in the Wireshark. As I did
not save USIM information in the HSS, I expected UE to be rejected with
PLMN_NOT_ALLOWED cause, but UE persistently sends Attach Request to the
network, and there is no Attach Reject in the response.
According to the Wireshark logs on the network side, MME sends the Attach
Reject message to the Srsenb. Unfortunately, it appears that the Srsenb
does not send it to the UE(I did not see any Attach Reject in Wireshark on
the UE side). What should I do? How can I fix this problem?
