Apparatus and method for controlling subscribers by using service interworking function of network for integrated internet protocol network

The present invention is a common subscriber in the next generation mobile communication network-based integrated Internet protocol (ALL-IP) network such as International Mobile Telecommunication (IMT-2000) and Universal Mobile Telecommunication Service (UMTS), which are currently being standardized in the European and North American manner. Integrated subscriber management device that can implement integrated management function by interworking device providing service quality management function, authentication and authorization management function, billing function and device providing mobility management function and database using database A method and a computer readable recording medium having recorded thereon a program for realizing the method.

Currently, the two main mechanisms of 3GPP (3 ^rd Generation Partnership Projects) and 3GPP2 of the International Conference on the Standardization of IMT-2000 system, the entire network, the Internet Protocol (IP: Internet Protocol) converged IP, based networks (All-IP) networks is issued It is expected to include the specifications for implementing the All-IP network in the 2000 standard.

This 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 preferably, the home location register (HLR), which is an existing circuit management server, is located in the subscriber server. It is necessary to integrate the Home Location Register (AUC) and the Authentication Administration Accounting (AAA) server, which is a packet management server, and define new functions.

In ALL-IP, subscriber processing server proposed to enable effective ALL-IP service including mobility management function, quality of service management function, authentication and authorization management function, and charging function.

Now, the conventional next generation mobile communication system will be described.

1 is a configuration diagram of a conventional next generation mobile communication system, in which "11" is a mobile station (MS), "12" is a base station transceiver subsystem (BTS), and "13" is a control station (BSC). : Base Station Controller, "14" is Mobile Switching Center (MSC), "15" is Home Location Register (HLR), "16" is Authorization / Accounting (AAA) "17" represents a packet data serving node (PDSN) and "131" represents a packet control function (PCF).

The mobile station (MS) 11 is in the range of any base station 12, and the information of the mobile station 11 is transmitted to the exchange station 14 via the base station 12 and the control station 13 controlling it, The information transmitted from 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 a user can carry and communicate with while moving. The mobile station 11 uses a forward channel when receiving data and a reverse direction when calling. Use a reverse channel.

The text message transmitted and received at the mobile station 11 is connected to the switching station 14 through the base station 12 and the control station 13 for high frequency signal processing and call processing.

The base station (BTS) 12 connects the mobile station 11 to the control station 13, and includes a digital channel unit (DCU), a timing / frequency control unit (TCU), and a radio frequency. It consists of a device (RFU: Radio Frequency Unit), and a Global Positioning System (GPS). In addition, the base station 12 performs a wired / wireless conversion function of communicating with the mobile station 11 over the air and communicating with the control station 13 by wire.

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 serves as a 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 network 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 location register (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 location register (VLR). The mobile station 11 and the subscriber's registered information are retrieved 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 using a unique algorithm with the mobile station 11 to check whether the mobile station 11 permits circuit network access when a telephone call is requested to the network. Perform

The authorization / authentication / billing (AAA) server 16 is an encryption key value for data encryption when the data service request of the mobile station 11 is transmitted from the packet network 17 to the packet network 17 and data is transmitted from the Internet, It performs the management function for the encryption level and the charging data collection function in the packet network 17.

As shown in FIG. 1, in the conventional next-generation mobile communication system, since a circuit network for voice and a packet network for data are separated, the subscriber server also uses the AAA server 16 and the HLR (AUC) ( Separated by 15).

As described above, in the next-generation mobile communication system, mobility and authentication functions are performed by separate procedures in different networks. However, since all-IP networks are integrated into one network, mobility and authentication functions are used in an existing circuit network. 15) and the authentication center (AUC), the call processing procedure becomes very complicated, and when the voice is transmitted through the Internet as an IP packet, proper encryption for the Internet may not be possible, which may cause problems in security functions. Therefore, in the ALL-IP network, procedures for mobility and authentication functions must be integrated to be suitable for the Internet. For this purpose, a method of integrating subscriber servers is essential.

The present invention devised to meet the above requirements, service quality management function, authentication and authorization management function, billing function using a common subscriber database in the next generation mobile communication network-based integrated Internet Protocol (ALL-IP) network, etc. An integrated subscriber management device for implementing an integrated management function by interworking a device providing a device with a device providing mobility management function and a service management function, and a method thereof, and a computer readable program recording a program for realizing the method.

Provides a computer-readable recording medium recording a program for realizing the function of integrated management, billing management and service management functions.

Currently, the ALL-IP concept has been introduced in 3GPP and 3GPP2, and the general trend is to integrate existing HLR, AUC, and AAA into one network element. Accordingly, the present invention proposes a common subscriber server (CSS) element to eliminate the existing HLR, AUC, AAA, and is suitable for the ALL-IP network, using a functional model of the integrated subscriber server (using a common subscriber DB). Separate the quality of service (QoS) management function, the authentication and authorization management function, and the billing function, and the service server model (mobility management function and service management function using a common subscriber database). And we propose a model to interwork between the two modules using the service interworking function.

By the way, the existing voice authentication process was authentication at the time of network access, but in ALL-IP where voice is transmitted in IP frame, bearer data (Bearer) is set after setting the Security Association (SA) function in the existing Internet. After encryption of data), a cipher translation procedure is required at the final node of the packet network.

In order to introduce such internet related authentication technology, SA setting and authentication key management function performed in AAA server of the existing packet network should be introduced, and the function for interworking with integrated subscriber server and service server should be included for effective call scenario. do. Therefore, the integrated subscriber server performs integrated functions such as QoS management function, authentication and authorization function, billing function, mobility management function, and service service function in charge of service management function, and service server manages mobility management and service management. It has a functional model that defines as independent network element and adds interworking function to integrated service server.

Thus, through the integrated subscriber server (CSS) capable of supporting the Internet authentication mechanism required for the ALL-IP network, compared to the AAA of the existing 3G mobile communication system, the present invention only needs to develop an interworking protocol by adding a service server interworking function. It can be standardized in time, and mobility management and service management, in particular, can reuse existing functions defined in Telephony.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a configuration diagram of an integrated subscriber management device using a service interworking function in an integrated Internet protocol (ALL-IP) network according to the present invention.

As shown in FIG. 2, an integrated subscriber management apparatus using a service interworking function in an integrated internet protocol (ALL-IP) network according to the present invention may support media (voice and stop) supported by an integrated internet protocol (ALL-IP) network. Mobile station 21 that satisfies video and video data, and the like, and manages radio resources and traffic on the radio of the mobile station 21, controls handoff, and manages the packet network 25 according to the request of the mobile station 21. And a wireless access network 22 for transmitting and receiving data and rearranging to meet the matching conditions, providing the mobile station 21 with voice and data to another mobile station 21, and the wireless access network 22 and the integrated subscriber server 24. Call control unit 23 for controlling and managing calls between mobile stations, and security related (SA) setting function for voice processing, and service quality management, authentication and authorization management for mobile station 21 through a common subscriber database. , And The integrated subscriber server 24 for integrating and managing interworking functions for interworking management and mobility management and service management functions, and a service server 26 for performing mobility management and service management functions through a common user database. Include.

The ALL-IP network has many differences compared to the network configuration of the existing next-generation mobile communication system (see FIG. 1). Specifically, as shown in FIG. 2, the IP control station 222 and the IP base station 221 are different. ) Is included in a radio access network (RAN) 22, and a call control unit 23 having a call control function instead of an MSC is provided.

In this case, the control station 222 disappears and the base station 221 itself may be directly attached to the IP network, that is, the base station 221 may be configured to be an IP node.

Accordingly, a considerable number of changes are expected in the configuration of the radio access network 22 including the IP base station 221, the IP control station 222, and the IP packet controller 223.

The radio access network 22 controls radio resource management and traffic on the radio and performs a handoff control function. In addition, in order to improve the quality of service, a series of processes of combining signals or selecting frames through handoffs are performed during handoff.

For reference, referring to the method in which the IP base station 221 becomes an IP node, by distributing the functions of the existing IP control station 222 to the IP base station 221 and the call control unit 23 of the core network, the IP control station ( 222 itself disappears and IP base station 221 becomes an IP node. There are some prerequisites for this.

First, the data transmitted from the mobile station 21 to the network at the time of soft handoff between the IP base stations 221 is improved through a diversity function. That is, the quality of the data is improved by combining or transmitting the data transmitted through the multipath.

However, since the frame selection function is a function located in the existing IP control station 222, it should be passed to the IP base station 221 or the core network. Since it is difficult to select a frame in the core network, the IP base station 221 It should be left. In this case, since problems such as frequent data generation between IP base stations 221 may occur, a solution to this, that is, location selection of a suitable diversity device is required.

Second, one of the considerations when selecting the location of the functional device for frame selection is that the quality of service is not sufficiently guaranteed on the Internet. Therefore, in the case of a frame selection function requiring real time processing, a problem solving method is required for the connection method between the implemented device and the IP base station 221.

To this end, first, the functional device for selecting a frame is divided into an IP base station 221 and an independent device (diversity device), and the connection between the device and the IP base station 221 is directly connected to a separate direct path (not an existing Internet path). There is a way to connect through Direct Path. In this case, the reason for using the direct path is to effectively perform the frame selection function, which is an important feature of the real-time processing, because the existing Internet does not satisfy the real-time characteristics sufficiently as mentioned in the above problem. Of course, if the Internet can guarantee sufficient real-time processing in the future, it is obvious that the direct path can be replaced by the Internet. In particular, various implementations are possible with respect to the location of diversity devices. Preferably, a diversity device is provided for each IP base station 221 in an ALL-IP network and a direct path between the diversity devices is provided. In addition, the device may support a frame selection function during soft handoff by providing a diversity device in units of several IP base stations 221 and a direct path between the diversity devices and between each IP base station 221 and the diversity device. In this case, the selection criterion may be a processing capacity of a diversity device.

The wireless access network 22 which can be implemented in various ways transmits data between the wireless access network 22 and the packet network 25 under the control of the IP control station 222 in the packet controller 223, but the wireless access network 22 and the packet network By adjusting the data rate between the (25) and rearranged the compressed data delivered through the packet network 25 to meet the matching conditions of the radio access network 22 and forwarded to the IP control station 222 to deliver the IP base station 221 To the mobile station 21 through. Further, the mobile station 21 controls and manages radio resources and traffic on the radio, and controls handoff, and transmits and receives data to and from the packet network 25 according to the request of the mobile station 21 and rearranges them to meet matching conditions. 21 to transmit the voice and data to the other mobile station (21).

Now, a detailed functional model of the integrated subscriber server 24 and service server 26 for the ALL-IP service is as follows.

The functional model of the unified subscriber server 24 for ALL-IP services is shown in FIG. 3A.

The integrated subscriber server 24 is a service server 26 having mobility management (MM) function and service management (SM) function which HLR had in the existing third generation mobile communication system or second generation mobile communication system. Integrated management of the authentication-related functions that AUC possesses. In addition, the service quality management function, the authentication management and the billing management function, which were in charge of the AAA server in the packet network of the third generation mobile communication system, also exist in the integrated subscriber server 24 and are designed to share the same subscriber database.

Looking at the protocol stack configuration of the integrated subscriber server 24 with reference to Figure 3a, the integrated subscriber server 24 uses the DIAMETER protocol as an application layer for quality of service, authentication and billing functions. In addition, a service server interworking function is provided to interwork with the service server 26 having mobility management (MM) and service management (SM) functions. The user datagram protocol / transmission control protocol (UDP / TCP) is used as the transport layer protocol, and the Internet protocol (IP) is used as the network layer protocol.

Meanwhile, referring to FIG. 3B, the protocol stack configuration of the service server 26, the service server 26 uses LDAP (Lightweight Directory Access Protocol) for mobility management (MM) and service management (MM) application layer. Used as Then, a linkage function for linking with the integrated subscriber server 24 is provided. In addition, user datagram protocol / transmission control protocol (UDP / TCP) is used as a transport layer protocol, and Internet protocol (IP) is used as a network layer protocol.

4 is a flowchart illustrating a location registration process in the integrated subscriber management method according to the present invention.

As shown in FIG. 4, FIG. 4 illustrates a location registration process of an integrated subscriber management method according to the present invention, wherein a session initiation protocol (SIP) is transmitted from an outgoing radio access network (RAN_O) to an outgoing call controller (CCF_O). When transmitting a location registration message (SIP) (401), the originating call control unit (CCF_O) transmits the location registration message to the service server to register the location (402).

5 is a flowchart illustrating a call setup process in the integrated subscriber management method according to the present invention.

As shown in FIG. 5, the call establishment process in the integrated subscriber management method through the functional model of the integrated subscriber server according to the present invention, first, the session initial protocol (SIP) from the originating radio access network (RAN_O) to the originating call controller (CCF_O). When the call establishment request message (SIP (Invite)) is transmitted (501), the originating call controller (CCF_O) sends a network access identifier (IMSI) to a terminal unique number (IMSI: International Mobile Station Identity) for identifying the received subscriber. After generating NAI: Network Access Identity, an access-request message of the DIAMETER protocol is generated and transmitted to the visited integrated subscriber server (CSS_V) (502). In this case, the visited integrated subscriber server CSS_V finds the home integrated subscriber server CSS_H and proxies the corresponding message (503).

Thereafter, when the home common subscriber server (CSS_H) requests service and mobility to the service server (504), the service server gives subscriber information (location and service related) (505).

Next, the home integrated subscriber server (CSS_H) forwards the access response message (Access-Response) of the DIAMETER protocol including the TLDN and the location (RAN_T IP address) of the RAN where the subscriber exists to the visit integrated subscriber server (CSS_V). (506), the visited integrated subscriber server (CSS_V) and the home integrated subscriber server (CSS_H) respectively transmit the IP_Sec_SetUp message of the DIAMETER protocol to set the security related (SA) to the originating and outgoing wireless access network (RAN_O, RAN_T) to the outgoing and outgoing radio. SAs are established between the access networks RAN_O and RAN_T (507,508).

Subsequently, when the access response message (Access-Response) is received from the visited integrated subscriber server (CSS_V) (509), the call setup from the originating call control unit (CCF_O) to the originating radio access network (RAN_O) to the destination radio access network (RAN_T) In order to transmit the rerouting request message (SIP (Move)) of the SIP protocol (510). 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) (511), and the incoming radio access network (RAN_T) sends a call to the outgoing radio access network (RAN_O). The setup completion message (SIP (OK)) is transmitted to notify that the call setup is completed (512).

The present invention as described above through the specific system configuration for the subscriber server field in the configuration of the next generation mobile communication system based on All-IP currently considered as a major standardization issue in 2000 by the standardization organizations (3GPP, 3GPP2, ITU, etc.) It is expected to not only promote the activation of the All-IP network but also to secure the initiative in system configuration in the subscriber server field among the All-IP networks.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention can be standardized in a short time because only the interworking protocol is developed by adding only the service server interworking function as compared to the AAA of the existing 3G mobile communication system, and in particular, the mobility management function and the service management function are existing. Has the effect of reusing functions defined in Telephony.
