LCS service messages over N1 Transport

  • 1.  LCS service messages over N1 Transport

    Posted Aug 09, 2022 08:09

    Can anyone please confirm if the LPP PDU sent by LMF to UE on NAS (N1) transport for location services are NOT ciphered?  TS 33.501 security architecture only refers back to TS 23.273 and TS 38.305. Both TS 23.273 & TS 38.305 specify only broadcast assistance data from LMF to UE to be optionally ciphered. All other messages by LMF transferred over N1N2 via AMF are completely transparent to AMF.

    Thank you.
