This second edition European Telecommunication Standard (ETS) gives the stage 2 description of the subscriber data management handling between the Home Location Register (HLR) and the Visitor Location Register (VLR). A number of procedures require updating of subscriber information from HLR to VLR:- location updating; restoration; modification of data by the operator; modification of data by the subscriber via the Mobile Station (MS). Only the rules for the updating of subscriber data from the HLR to the VLR are described in this ETS. Public Land Mobile Network (PLMN) specific and Unstructured Supplementary Service Data (USSD) subscriber data are out of scope of this ETS.
