Hi Pix

Yes happening in one cell and only one UE involved.

Checked the CAP file, NAS-PDU, etc.

Some interesting stuff. The EUTRAN-CGI shows correct MCC but MNC is Inactive. The EPS mobile identity – Old GUTI containing IMSI decodes to MCC in Europe and MNC in Indian? There is No TMSI identified. This UE is attempting combined TAU + IMSI Attach, yet not EMM connected?

Not sure reason 250ms
