[srsran-users] OnePlus Nord 5G can't see 5G SA cell even using commercial plmn

[Tu Kai]

Issue Description
Hello,

I fully followed this note
<https://docs.srsran.com/en/latest/app_notes/source/5g_sa_COTS/source/index.html>
The
srsenb and Open5GS works properly, but my UE Oneplus Nord 5G can’t see the
5G SA gNB signal. I tried to set mmc and mnc as the same as the note, and I
also tried set mmc and mnc to 001 01. None of the them works. I also tried
to set a commercial mmc and mnc, and I failed again.

Setup Details
Operation System: Ubuntu 20.04
srsRAN 22.04
RF: USRP B210(with 2 VERT900 antennas)
UE: Oneplus Nord 5G
Card type: Sysmocom USIM(sysmoUSIM-SJA2)
Sim card configuration:
Generated card parameters :
 > Name     : Magic
 > SMSP     : e1ffffffffffffffffffffffff0581005155f5ffffffffffff000000
 > ICCID    : 8988211000000452618
 > MCC/MNC  : 901/70
 > IMSI     : 901701234567895
 > Ki       : 00000000000000000000000064617665
 > OPC      : 64097b52589f63f12eec5172b49929d9
 > ACC      : None
 > ADM1(hex): 3439393633353439
 > OPMODE   : None

Expected Behavior
OnePlus Nord 5G detect the 5G SA network.

Actual Behaviour
OnePlus Nord 5G can’t search 5G SA network.

Steps to reproduce the problem
After running the gNB the NG connection is successful and the gNB is
connected to the AMF. But my Oneplus Nord 5G can’t see it.

Additional Information
I have several questions in this case:

   1. Which antenna model are used in this note?
   2. What is the model of the USIM are used in this note?
   3. What is the the configuration for the USIM in this note? Can anyone
   share a script and configuration of USIM that works? I’m not sure whether
   it is the USIM problem leads to UE can’t see the 5G cell.
   4. Any help is appreciated!
