For each UE subscriber the UDM stores LCS related data as part of the Subscriber Data Management (SDM) service as defined in clause 5.2.3.3.1 of TS 23.502.

The privacy profile data is defined in Table 7.1-1 containing data for the privacy classes for which location of the target UE is permitted. For the meaning of each LCS privacy profile data type and included data, refer to clause 5.4.2.
