Method for enhancement of subscriber profile data sameness HLR between VLR in mobile station center system

摘要

PURPOSE: A method for improving data inconsistency between an HLR and a VLR in a mobile switching system is provided to change an MAP processing method in a receiving MSC without changing location information of a mobile station in an HLR, even when an error MAP is generated, and to transmit location inquiry information that is not updated to an originating MSC, thereby improving data inconsistency. CONSTITUTION: A VLR(200) transmits a location registration request message to an HLR(300) at the request of a subscriber mobile station(100), and enables a new location registration process to be executed(S10). An MSC stores location-registered time of the HLR(300) from a VLR(200) in relation to location registration, and requests a re-location registration process of the VLR(200) at certain intervals(S20). If the mobile station(100) attempts originating a call while the re-location registration information is not received from the mobile station(100)(S30), location registration information of a corresponding subscriber is automatically updated to the HLR(300), to complete a location registration process of the mobile station(100)(S40).
