Abstract: PROBLEM TO BE SOLVED: To provide a device, method, and system by which a default mode is provided about an authentication failure on a mobile communication network, particularly, a specific type of authentication failure including an authentication information updating failure can be detected and informed to a subscriber and, at the same time, can be corrected. SOLUTION: Representatively, the method is used for providing a default mode about an authentication failure on a mobile communication network accessed from a mobile unit through a call leg. The method includes a step of performing an authenticating procedure. When the authenticating procedure is failed, the communication session to the mobile unit is terminated by refusing the request from the mobile unit for performing access to a network and the announcement on the call leg is provided to the mobile unit.

Abstract: PROBLEM TO BE SOLVED: To retrieve a voice mail from a mobile station during roaming. SOLUTION: When a call is sent from a public telephone exchange network 102 to a mobile station 108 of a mobile electric communication system 100, a ground system sets a path of the call to a proper exchange component 104 in a mobile system. The exchange component 104 transfers a dialed number to a registration component 106 to which the mobile station is assigned with other information to make a request of transfer information of the mobile station 108. The registration component 106 returns the transfer information to the exchange component 104. A serving system 105 includes a database in the registration component 106 and the database includes the relation between the identifier of the mobile station and the directory number of the mobile station.
