    Hi,

    Can anyone please confirm if the LPP PDU from LMF to UE on NAS (N1) transport for location services are in clear and not ciphered?  TS 33.501 security architecture refers back to TS 23.273 and TS 38.305 which say only broadcast assistance data from LMF to UE is optionally ciphered.

    Thank you.

    Rgds,
    Chitta
