Why is it handled as an emergency registration? - Where is you conclusion
based upon?

There is no "sos" SIP URI parameter in Contact header, therefore it is not
an emergency registration.

  What I see from the screenshot is, that only a check for emergency flag has
  been done.
  
  That does not mean that an emergency flag has been detected.
  
  Check pcscf.cfg for the sequence of function calls.

Nayan Jain - 2015-10-26

Thanks Franz Edler for clarification.

I have observed that UE send the" REGISTER" message to IMS and IMS send "401 Unauthorized - Challenging the UE" message.

"401 Unauthorized - Challenging the UE" message is not reaching up to UE, I can see this message in EPC and eNB log file but it dosn't reach to UE.Attached log file for your reference.

What can be the issue?

  I wonder anyhow about your configuration.
  
  REGISTER requests are sent by 192.168.0.230 (the UE?) to 192.168.0.141:4060
  (P-CSCF ?) for three times. Why?
  
  Where did you trace?
  
  What is between P-CSCF and the UE in your configuration?

Hello Franz Edler,

Please find attached setup which I am using for IMS registration.

Please find below my inline comments on your queries -
Where did you trace?
<nayan> I have taken log at EPC and eNB</nayan>

What is between P-CSCF and the UE in your configuration?
<nayan> In between UE and P-CSCF - eNB and EPC are there</nayan>

REGISTER requests are sent by 192.168.0.230 (the UE?) to 192.168.0.141:4060
<nayan> Yes UE IP is 192.168.0.230 and IMS IP is 192.168.0.141. I am using IMS port 4060 for registration.</nayan>

Let me know if you need any more information.

Regards

Nayan Jain
