Abstract
A telecommunications system and method is disclosed for defining restricted positioning areas by geographical location. The restricted area information can be established by the cellular network or the mobile subscriber, and can be stored in a database, such as an Intelligent Network (IN) node. An IN trigger can be included in the subscriber information provided to the serving Mobile Switching Center/Visitor Location Register (MSC/VLR) or the IN trigger can be stored in specific MSC/VLR's that have restricted positioning areas for all mobile subscribers. Upon receiving the calculated location estimate, the IN trigger is activated, and the MSC/VLR transmits the calculated location estimate to the IN node to determine whether the calculated location estimate can be provided to the requesting Location Services (LCS) client based upon the defined restricted positioning area information.
