Method of managing shared file and device for authenticating subscriber by using same

Abstract

A method of managing a file of a subscriber authenticating module embedded in a terminal device and a module for authenticating a subscriber by using the method. The method of managing the file includes configuring a file structure for one or more profiles and managing one or more files included in the file structure in response to a request. Thus, the method is efficient for a multiple-profile environment.

         22 . A method of managing files of a subscriber certification module comprising:
 forming a file structure having at least one profile for providing network access to a mobile terminal;   storing the formed file structure on the subscriber certification module which is a card embedded into the mobile terminal; and   managing said at least one file in the file structure in response to a request,   wherein the managing comprises at least one of updating, deleting, and adding an access profile for the network access in the file structure.   
     
     
         23 . The method according to  claim 22 ,
 wherein the at least one file comprises state information of at least one network access application.   
     
     
         24 . The method according to  claim 22 ,
 wherein the file structure comprises a master file, and at least one file associated with the master file.   
     
     
         25 . The method according to  claim 24 ,
 wherein the at least one file associated with the master file comprises an application directory file, which comprises a network access application list and state information of each network access application in the network access application list.   
     
     
         26 . The method according to  claim 25 ,
 wherein a state of said each network access application is an activated state or a deactivated state.   
     
     
         27 . The method according to  claim 22 , further comprising:
 receiving the request from an external interworking device.   
     
     
         28 . The method according to  claim 27 ,
 wherein the external interworking device comprises a mobile network operator server or a subscription manager server.   
     
     
         29 . The method according to  claim 22 , further comprising:
 receiving the request from a shared file manager or a profile located in the subscriber certification module.   
     
     
         30 . The method according to  claim 25 ,
 wherein the managing of said at least one file included in the file structure in response to the request comprises updating data stored in the application directory file in response to a request with an access right.   
     
     
         31 . The method according to  claim 30 ,
 wherein the access right is based on an administrator certification.   
     
     
         32 . The method according to  claim 22 ,
 wherein the managing of the at least one file included in the file structure in response to the request further comprises registering network access application related information for an added profile in response to a new profile being installed onto the subscriber certification module.   
     
     
         33 . A subscriber certification card built into and installed in a mobile terminal apparatus, the subscriber certification card comprising:
 a shared file memory configured to store at least one profile-related file and at least one corresponding network access application with state information; and   a processor configured to manage the at least one profile-related file,   wherein the processor manages the at least one profile-related file by updating, deleting, or adding at least one of a network access application and data therein.   
     
     
         34 . The subscriber certification card according to  claim 33 ,
 wherein the shared file memory is further configured to store a master file, and at least one file associated with the master file.   
     
     
         35 . The subscriber certification card according to  claim 34 ,
 wherein the at least one file associated with the master file comprises an application directory file, wherein the application directory file comprises a network access application list and state information of each network access application in the network application list.   
     
     
         36 . The subscriber certification card according to  claim 33 , further comprising:
 a shared file manager configured to manage at least one file in the shared file memory.   
     
     
         37 . The subscriber certification card according to  claim 33 ,
 wherein subscriber certification card is an embedded universal integrated circuit card built into the mobile terminal apparatus.   
     
     
         38 . The subscriber certification card according to  claim 33 ,
 wherein at least one of: at least one file and file information stored in the shared file memory is changed in response to a request from at least one of the processor and an external interworking device remote from the mobile terminal apparatus.   
     
     
         39 . The subscriber certification apparatus according to  claim 38 ,
 wherein the external interworking device comprises a mobile network operator server or a subscription manager server.   
     
     
         40 . The subscriber certification apparatus according to  claim 39 ,
 wherein data stored in an application directory file is updated in response to the request with an access right.   
     
     
         41 . The subscriber certification apparatus according to  claim 40 ,
 wherein the access right for updating is based on an administrator certification.   
     
     
         42 . The subscriber certification apparatus according to  claim 33 ,
 wherein a state of the network access application is one of an activated state and a deactivated state.   
     
     
         43 . The method of  claim 22 , wherein the subscriber certification module is an embedded universal integrated circuit card built into the mobile terminal.
