Abstract: PROBLEM TO BE SOLVED: To provide a method for limiting the number of calls to be simultaneously transferred in a mobile unit. SOLUTION: A call is originated to the mobile unit. This call origination request is transmitted to an MSC related to the mobile unit. When the mobile unit is not valid in the MSC at present, the MSC transmits a location request to an SCP. The SCP responds a return message containing the directory number (TLDN) of temporary location and an indicator. The MSC checks the present number of calls simultaneously transferred in the mobile unit. When the present number of simultaneously transferred calls exceeds a threshold, the MSC does not transfer any call. When the number of simultaneously transferred calls does not exceed the threshold, the MSC transfers a call to the mobile unit by transmitting it to the TLDN.

Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently finding out a mobile unit in a multiple technology environment without wasting a bandwidth on a transmission control channel for each technology. SOLUTION: The apparatus includes a home location register 203 that stores records for mobile units in a home system 201. A visited location register 213 stores records for mobile units presently registered in a visited system 211 in which the visited location register 213 is located. The visited system 211 identifies a last accessed technology by a mobile unit 221 in the visited system 211 and forwards the identification of the last accessed technology to the home location register 203. The identification of the last accessed technology may be forwarded to the home location register in a registration notification. The home system 201 may forward a routing request including the identification of the last accessed technology to the visited system.

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.
