Common subscriber managing apparatus and method based on functional modeling of a common subscriber server for use in an ALL-IP network

Abstract

A common subscriber managing apparatus and method for use in an all Internet Protocol network integrating a circuit network for voice and a packet network for data. The apparatus comprises a portable user terminating unit satisfying media standards supported in the network, a wireless interfacing unit controlling wireless resources of the user terminating unit and wireless traffic, controlling handoff, realigning data from and to the packet network upon interface request of the user terminating unit, providing realigned data to the user terminating unit and transferring media to another user terminating unit, a call controlling unit controlling a call between the wireless interfacing unit and common subscriber managing unit, and common subscriber managing unit for providing Security Association setup function for voice processing and commonly managing mobility management, Quality of Service, authentication and authorization management, accounting management and service management functions for the user terminating unit through a common subscriber database.

       13 . In an Internet Protocol network having a processor, a computer readable recording medium for recording a program for implementing the functions of: 
 (a) modeling to provide, by a server, mobility management, Quality of Service, authentication and authorization management, accounting management and service management functions for a roaming terminal by using a common subscriber database for Internet Protocol service; and    (b) setting a Security Association function for voice processing by setting up a call between an Internet Protocol visiting network and a home network by the server and commonly managing the mobility management, Quality of Service, authentication and authorization management, accounting management, and service management functions.    
   
   
       14 . A common subscriber server for use in an Internet Protocol network in which a circuit network for voice and a packet network for data are integrated, comprising: 
 a common subscriber managing block for providing authentication management commonly in basis of the circuit network and the packet network; and    a call controlling block for controlling a call between the common subscriber managing block and the mobile station.    
   
   
       15 . The common subscriber server as recited in  claim 14 , wherein the common subscriber managing block provides Security Association setup function for voice processing in the circuit network.  
   
   
       16 . The common subscriber server as recited in  claim 14 , wherein the common subscriber managing block provides mobility management, authorization management and service management functions.  
   
   
       17 . The common subscriber server as recited in  claim 16 , wherein the common subscriber managing block provides accounting management.  
   
   
       18 . The common subscriber server as recited in  claim 17 , wherein the common subscriber managing block provides Quality of Service.  
   
   
       19 . The common subscriber server as recited in  claim 17 , wherein the common subscriber managing block uses at least one of common subscriber database.  
   
   
       20 . The common subscriber server as recited in  claim 19 , wherein common subscriber managing block uses a DIAMETER protocol as application layer protocol.  
   
   
       21 . The common subscriber server as recited in  claim 19 , wherein said common subscriber managing block uses a User Datagram Protocol/Transmission Control Protocol as a transmission layer protocol.  
   
   
       22 . The common subscriber server as recited in  claim 19 , wherein said common subscriber managing block uses an Internet Protocol as a network layer protocol.  
   
   
       23 . The common subscriber server as recited in  claim 19 , wherein the common subscriber managing block uses a LDAP protocol for management functions.  
   
   
       24 . The common subscriber server as recited in  claim 14 , further comprising a service managing block for performing the service management functions.  
   
   
       25 . A mobile communication system in which a circuit network for voice and a packet network for data are integrated, comprising: 
 a mobile station satisfying media voice or data standard supported in the network;    a radio access network (RAN) including a wireless interfacing block for controlling wireless traffic transmitted from and to the mobile station; and    a network including a common subscriber server having a common subscriber managing block for providing authentication management commonly in basis of the circuit network and the packet network and a call controlling block for controlling a call between the common subscriber managing block and the mobile station.    
   
   
       26 . The mobile communication system as recited in  claim 25 , wherein the radio access network (RAN) controls wireless resources of the mobile station and handoff, realigns data from and to the packet network based on a request of the mobile station to have interfacing condition, provides the realigned data to the mobile station, and transfers the media to another mobile station.  
   
   
       27 . The common subscriber server as recited in  claim 25 , wherein the common subscriber managing block provides Security Association setup function for voice processing in the circuit network.  
   
   
       28 . The common subscriber server as recited in  claim 25 , wherein the common subscriber managing block provides mobility management, authorization management and service management functions.  
   
   
       29 . The common subscriber server as recited in  claim 25 , wherein the common subscriber managing block provides accounting management.  
   
   
       30 . The common subscriber server as recited in  claim 29 , wherein the common subscriber managing block provides Quality of Service.  
   
   
       31 . The common subscriber server as recited in  claim 29 , wherein the common subscriber managing block uses at least one of common subscriber database.  
   
   
       32 . The common subscriber server as recited in  claim 31 , wherein common subscriber managing block uses a DIAMETER protocol as application layer protocol.  
   
   
       33 . The common subscriber server as recited in  claim 31 , wherein said common subscriber managing block uses a User Datagram Protocol/Transmission Control Protocol as a transmission layer protocol.  
   
   
       34 . The common subscriber server as recited in  claim 31 , wherein said common subscriber managing block uses an Internet Protocol as a network layer protocol.  
   
   
       35 . The common subscriber server as recited in  claim 31 , wherein the common subscriber managing block uses a LDAP protocol for management functions.  
   
   
       36 . The common subscriber server as recited in  claim 25 , further comprising a service managing block for performing the service management functions.
