A telecommunications system and method is disclosed for implementing Location Override Key(s) (LOKs) within location services in order to determine whether certain checks on subscriber limitations and/or system default behavior are applicable or not for a particular location request. Each LOK can either have the value override or not override associated therewith, and each Location Application (LA) can be associated with a particular value of an LOK. In addition, an LOK can be accompanied by one or more additional parameters related to the particular LOK. For example, location services can provide LAs with a Privacy Override Key (POK), which can have a value of “override” or “not override”. If the POK is set to “override”, the privacy settings of the subscriber to be positioned shall be overridden for the particular positioning request in most cases only if the subscriber to be positioned is in the same Public Land Mobile Network (PLMN) as the Gateway Mobile Location Center (GMLC) that received the positioning request.
