The present invention provides a mobility management function (QoS) management function, authentication and authorization management function, billing function (AAA) using a common subscriber database (DB) in an integrated Internet protocol (ALL-IP) network, etc. The present invention relates to an integrated subscriber management device capable of managing a linkage function with a call processing management server and the like and a method thereof, and a computer-readable recording medium having recorded thereon a program for realizing the method.

IMT-2000 (International Mobile) is a third generation future airborne land mobile communication system (FPLMTS) that overcomes the limitations of local and voice-centricity of conventional mobile communication and provides non-voice (voice, data, video, etc.) regardless of region. Next-generation mobile communication services such as Telecommunication (UM) and Universal Mobile Telecommunication Service (UMTS) are in progress.

An example of a next generation mobile communication system that provides such a service is shown in FIG. 1. The conventional IMT-2000 mobile communication system as shown in FIG. 1 basically consists of a circuit network 1 for voice service and a packet network 2 for data service. The circuit network 1 is a mobile station (MS) (Mobile Station-11), a base station (BTS: Base Station Transceiver Subsystem-12), a control station (BSC: BaseStation Controller-13), a switching station (MSC: Mobile Switching Center-14), home It includes components such as a Home Location Register-15 (HLR), and the packet network includes an Authorization Authentication Accounting-16 (AAA) server and a Packet Data Serving Node-PDSN (PDSN). ), And a packet control function (PCF: Packet Control Function-131).

In this next generation mobile communication system, the mobile station (MS) 11 is within the range of an arbitrary base station 12, and the information of the mobile station 11 passes through the base station 12 and the control station 13 controlling the switching station 14 Information transmitted from the exchange station 14 is transmitted to the mobile station 11 via the base station 12 and the control station 13. The mobile station 11 is a wireless terminal including a mobile terminal, a personal digital assistant (PDA), etc., which the user can carry and communicate with while moving.

The base station (BTS) 12 is responsible for connecting the mobile station 11 to the control station 13, and communicates with the mobile station 11 by radio, and performs communication with the control station 13 by wire. Perform wired / wireless conversion function.

The control station (BSC) 13 connects the base station 12 to the switching center 14 to coordinate the connection between the base stations 12 and is responsible for the signal processing function for communication between the base station 12 and the switching station 14. . The packet control unit 131 in the control station 13 processes multimedia data in cooperation with the packet data service node 17.

The switching center (MSC) 14 has a visitor location register (VLR) and works in conjunction with the home location register 15 to process mobile communication subscriber calls. The exchange station 14 connects with the control station 13 to perform call setup and release functions of the mobile station 11 and to perform various functions related to call processing and additional services.

Here, the visitor locator VLR is a database that temporarily stores subscriber information related to the mobile station 11 while the mobile station 11 is in an area controlled by the visitor locator VLR. The mobile station 11 and the subscriber having moved and registered their location are taken from the home location register 15 and temporarily stored therein, and mounted in the switching station 14.

The home location register (HLR) 15, which is a circuit management server, is a database that is connected to the switching center 14 and manages various information of mobile subscribers, and functions to register subscriber locations in conjunction with various switching centers 14. It stores the permanent information and location information of the mobile station 11 and subscribers, and interacts with the visitor location register (VLR) to support various functions related to call processing and additional services. In particular, it provides voice call-related mobility and service-related functions in a circuit network.

In addition, the authentication center (AUC), which is a circuit management server, authenticates the mobile station 11 by using a unique algorithm with the mobile station 11 to check whether the mobile station 11 permits access to the circuit network when the telephone is requested to the network. Perform

An authorization / authentication / billing (AAA) server 16 performs authentication, authorization verification, and billing functions for a user. For this purpose, RADIUS protocol is used and FAAA (Foreign AAA) is located in the external network to proxy (Home AAA) in the home network. Through this, Simple IP / Mobile IP based service billing information collection function, Mobile IP registration authentication function, Dial-in service user authentication / authorization verification function are performed.

The packet data service node (PDSN) 17 is responsible for the interface between the two networks between the Radio Access Network (RAN) and the Data Core Network (DCN). That is, the data link layer is terminated from the mobile station and routed to a higher layer protocol on the data network. In this case, a simple IP call is directly connected to the IP network, and a mobile IP call is connected to the home agent HA through a GRE tunnel.

The home agent 18 acts as a gateway for mobile IP users to connect to the Internet. The home agent 18 performs tunneling with the PDSN 17 for MIP registration and delivers MIP call packets from the home network to the PDSN 17.

As shown in FIG. 1, since the line network 1 for voice service and the packet network 2 for data are separated in the conventional next-generation mobile communication system, the subscriber server also has an AAA server 16 and an HLR (AUC). It is separated by 15.

The next generation mobile communication system is based on IPv6 (Internet Protocol version 6), and it is sure to evolve into the fourth generation ALL-IP network, a comprehensive information and communication network that can provide real-time / non-real-time multimedia services such as voice, video, and data. It is becoming. One of these movements has been progress toward standardization of the entire network of IMT-2000 systems to IP (Internet Protocol) based networks, led by the 3GPP (3 ^rd Generation Partnership Projects) and 3GPP2. As shown in FIG. 2, the ALL-IP core network integrates the Internet protocol in providing a mobile communication service by integrating a third generation wireless network, a WLAN, a DSL, a PSTN, a legacy cellular, and an Internet network. Provides seamless handoff, maximizes synergy effect by using IP network, provides simultaneous voice data and real-time multimedia service, enhances service control, utilizes Internet service of IP client terminal, and costs through packet transmission It is a mobile communication service of dream that can realize savings.

The ALL-IP network has many differences compared with the network configuration of the conventional next generation mobile communication system as shown in FIG. 1, but is preferably a home location register (HLR), which is a conventional line management server. / Authentication Center (AUC) and Authorization Authentication Accounting (AAA) server, which is a packet management server, need integration and new function definition.

In the ALL-IP network, since the circuit network and the packet network are integrated into one network, the call processing procedure becomes very complicated when using the HLR 15 and the authentication center (AUC) for mobility management and authentication functions used in the existing circuit network. In addition, the authentication process of the existing voice was authentication when accessing the network, whereas in the ALL-IP network where voice is transmitted in IP frames, the packet network after encryption of bearer data after security association is performed on the existing Internet. Authentication is performed at the final node of the server by the encryption translation procedure. When voice is transmitted through the Internet as an IP packet, proper encryption for the Internet is impossible, which may cause a problem in the security function.

Therefore, mobility, authentication, authorization, and billing functions should be integrated for effective call processing in ALL-IP network, and security setting and authentication key management function performed in AAA of packet network to introduce internet related authentication technology. In order to integrate the subscriber server is required.

As shown in FIG. 6, the call establishment process in the integrated subscriber management method according to the present invention first establishes a call of a Session Initiation Protocol (SIP) from an outgoing radio access network (RAN_O) to an outgoing call controller (CCF_O). When the request message (SIP (Invite)) is transmitted (601), the originating call control unit (CCF_O) uses a network access identifier (NAI: Network Access Identity) as a terminal unique number (IMSI: International Mobile Station Identity) for identifying the received subscriber. After generating the identity, an access request message (Access-Request) of the DIAMETER protocol is generated and transmitted to the visited common subscriber server (CSS_V) (602). At this time, the visited common subscriber server CSS_V finds the home common subscriber server CSS_H and proxies the corresponding message (603).

Thereafter, the home common subscriber server (CSS_H) sends a service request message (SVC_Request) containing the IMSI to the service server in charge of the service management function and requests the service (604). In response to the request, the service server sends a subscriber service related profile to the home common subscriber server CSS_H in the response message SVC_Response for the service request message (605).

Security settings are completed between the destination radio access networks RAN_O and RAN_T (608 and 609).

Subsequently, when the access response message (Access-Response) is received from the visited common subscriber server (CSS_V) (607), the originating call control unit (CCF_O) sends a SIP (Invite) which is a call setup request message of the SIP protocol to the mobility management server (MM). (610). The mobility management server has a SIP (Option) and transmits it to the incoming call control unit (CCF_T) (611).

When the incoming call control unit CCF_T forwards the call setup completion message (SIP (OK)) to the mobility management server (MM) with the temporary connection number (TLDN) of the called party (612), the mobility management server (MM) The call setup completion message SIP (OK) is transmitted to the incoming call controller CCF_O (613).

The originating call control unit CCF_O receiving the access response transmits a rerouting request message (SIP (Move)) of the SIP protocol to establish a call to the terminating radio access network (RAN_T) to the originating radio access network (RAN_O) (614). . At this time, the outgoing radio access network RAN_O forwards a call setup request message (SIP (Invite)) to the incoming radio access network (RAN_T) (615), and the incoming radio access network (RAN_T) sends the call to the outgoing radio access network (RAN_O). The call setup completion message (SIP (OK)) is transmitted to notify that the call setup is completed (616).
