Hi, This is actually an issue with the phone, which remembers the settings from the first registration. |

We have two separate instances of 5GS Core with its own Radios.... One instance is setup with ST 1 and SD a1 and the other 5GS Core is setup with ST 1 and SD 1.....
In both instances we have a subscriber configured with respective SD values ie 1 and a1......
The problem is when i connect a devices to Core 1 with SD value a1 it registers with no issues and call is successful.
But
When the i connect the same device to Core 2 that has SD 1 then registration rejects (please note that subscriber provisioned with correct SD i.e 1 in Core 2)
[gmm] ERROR: Cannot find Requested NSSAI [1] (../src/amf/gmm-handler.c:393)
[gmm] ERROR: PLMN_ID[MCC:999 MNC:123] (../src/amf/gmm-handler.c:397)
[gmm] ERROR: S_NSSAI[SST:1 SD:0xa1] (../src/amf/gmm-handler.c:400)

Somehow the device still registering with SD a1 as it saved that value from its previous interaction with 5GS Core when it should be registering it with SD 1 ......
Please note i have 5GS 2.7 amd i have amf.yaml and nssf.yaml configured with correct sd values in both 5G instances**
What i have done....
reset network settings on Devices and rebooting
deleting subscriber and creating new
restarting 5GS
**Please also Note
Sometimes when i burn a new SIM card with a different IMSI the same devices then registers with no issues......burn a new SIM with a new IMSI and registers with Core 1 ... Burn another SIM with a different IMSI and then it registers with Core 2...........
Why 5GS failing this registration.... Thank you
But device keeps on sending SD a1 when that subscriber is configured with SD1
