Hi Gents,

  1. What Could be reasons if RNC is sending “Failure in Radio Interface Procedure” message toward SGS?.
  2. How we can avoid it “Solutions/Work Around”?
  3. Any impact of this cause code in KPIs if SGSN does not ignore this message?

Thank You.

Hello dears,

I am also interested to know in which situations we get the failure in the radio interface procedure (14).

If I understand your question, when the UTRAN or the UE is unable to support the ciphering and/or integrity protection algorithms specified in the SECURITY MODE COMMAND message, then the UTRAN shall return to CN a SECURITY MODE REJECT message ‘radio interface Security Control Procedure fails’.
