Filed: 1998-08-03
Abstract: PURPOSE: Effective overall name management method of a mobile switching system processes effective overall name message for a number translation by using effective overall name table, manages a data table required for the overall number translation by using a received message, adds effective overall name to the data table. and deletes effective overall name from the data table. CONSTITUTION: The effective overall name management method performs error test, abolishes a corresponding message when the message has the error. If there is no error, the method examines address commander of a message receiving part area, and determines (410) overall name translation. If the overall name translation is not determined, the method determines (422) whether a destination of the message is an oneself station or another station. If the self-station is determined, the method requests (426) a message transmission from a user part when the destination is actually in the self-subsystem. If the destination is not in the self-subsystem, the method informs a rooting failure. If the destination is another station, the message is abolished (428), and a response of the requested message transmission is terminated. If the overall name translation is determined, the method performs (412) overall name translation mode through overall name translation table, determines whether the translation result is a self-station, another station, or the rooting failure. If the self-station is determined, the method requests (418) a message transmission to the user part. If the another station is determined, the method inserts (420) a signal point value of a corresponding station and a signal point value of a self-station into a rooting table, and requests a message transmission. If the rooting failure is determined, the method informs (430) a cause of the rooting failure, and terminates a response of the requested message transmission.
