Description

Transaction processing method and system of high speed packet data communication system {Method and System for Controlling of Transaction in HRPD}

The present invention relates to a technique for processing transactions occurring in a high speed packet data communication system. More specifically, the service of service cancellation, suspension of use, and number change occurring during the use of the high-speed packet data communication service is handled using a home location register that manages the location information of the customer using the high-speed packet data communication service. To a method and system.

Currently, the mobile communication system is rapidly changing from a conventional voice call-oriented communication service to data communication providing a game, an image, a video, and the like. Looking at the evolution of wireless mobile communication technology, the second generation of cellular (Celluar) / Personal Communication Service (PCS) followed by the first generation of analog Advanced Mobile Phone Systems (AMPS) and the current technology under development The third generation of high-speed data communication is IMT-2000 (International Mobile Telecommunication-2000) in order.

IMT-2000 refers to a multimedia mobile communication service of a wired / wireless home concept that can transmit and receive voice, data, and video at high speed in a wired / wireless environment with one terminal. The service can be used from a single terminal or user access card anywhere in the world, and the global roaming is possible by using the same frequency as well as standardizing related technologies.

Meanwhile, the two largest organizations in the 3GPP (3 _rd Generation Partnership Projects) and 3GPP2 standards of international meetings to standardize the IMT-2000 system. In particular, 3GPP2, which is proceeding with the standardization of the synchronous IMT-2000 system, focuses on the standardization of the wireless connection and core network of the American National Standard Institute (ANSI) -41 network and the synchronous CDMA2000 based thereon. . Wireless access standards standardized by 3GPP2 include CDMA2000-1X / EV-D0 (EVolution-Data Only), which is an evolution of CDMA2000-1X and CDMA2000-1X. CDMA2000-1X provides a unidirectional high speed data service with a transmission rate of up to 307.2 Kbps in a form of a mixture of a circuit network and a packet network. CDMA2000-1X / EV-DO, on the other hand, provides bidirectional high-speed data service with a transmission rate of up to 2.4Mbps for packet networks only. Therefore, a packet data communication system according to the CDMA2000-1X / EV-D0 wireless access standard requires a system configuration dedicated to a packet network, not a system configuration in which a circuit network and a packet network of the CDMA2000-1X are mixed.

1 is a block diagram schematically illustrating a communication system for a conventional high speed packet data communication.

1, a conventional high rate packet data (HRPD) communication system includes an access terminal (AT) 100 and an access terminal transceiver subsystem (ANTS) 112. And an access network (AN) 110 including a control station (ANC: Access Network Controller) 114 is wirelessly connected, and an access network authentication server (AN-AAA: Access Network-Authorization Authentication Accounting) ( 130, the Packet Data Serving Node (PDSN) 140, the Customer Information Center 150, the AAA-Authorization Authentication Accounting (AAA) 160, or the LAN 120 or WAN. It is connected through a WAN (not shown).

The access terminal 100 is located within the range of any base station 114, and information of the access terminal 100 is transmitted to the base station 114 and the control station 114 controlling it, and transmitted from the control station 114. The information is transmitted to the access terminal 100 via the base station 114.

The access terminal 100 is a wireless terminal including a mobile communication terminal, a notebook computer, a personal digital assistant (PDA), and the like, which the user can carry and communicate with, and when the data is received, is a forward channel. In the case of transmitting data, the reverse channel is used.

The base station 112 connects the access terminal 100 to the control station 114, and includes a digital channel unit (DCU), a timing / frequency control unit (TCU), and a radio frequency device ( It includes equipment such as Radio Frequency Unit (RFU) and Global Positioning System (GPS). In addition, the base station 112 wirelessly communicates with the access terminal 100 and performs a wire / wireless conversion function of performing communication with the control station 114 by wire.

The control station 114 coordinates the connection between the plurality of base stations 112, and serves to adjust the circuit use of the base station 112, or when an abnormal situation occurs. The packet control function (PCF) 116 in the control station 114 functions to process packet data in cooperation with the packet data serving node 140.

The access network authentication server 130 authenticates the access terminal 100 to use the packet data service through the access network 110 and performs a function of authorizing the service. Therefore, the access network authentication server 130 is a terminal identification number (MIN: Mobile Identification Number, MIN) of the customer who applied for the packet data service according to the present invention, the ESN (Electronic Serial Number) and service request of the terminal, Stores service status information such as termination, sending / stopping, etc.

Here, the access network authentication server 130 authenticates the access terminal 100 accessing the access network 110 by using a standardized Challenge Handshake Authentication Protocol (CHAP). Here, the Challenge Handshake Authentication Protocol is one of the authentication protocols for the Point-to-Point Protocol (PPP) used for dial-up Internet Protocol (IP) connection. This refers to a technology for authenticating a terminal by encrypting and transmitting a password.

The packet data serving node 140 functions to provide a packet data service to the access terminal 100, and is connected to the Internet 170 to provide various multimedia services to the access terminal 100. The packet data serving node 140 is an evolution of an inter-working function (IWF) used to support data communication in a second generation (2G) communication system. The packet data serving node 140 charges according to the amount of packets used for the access terminal 100 using the packet data service.

The customer data distribution system (CDS) 150 uses the access terminal 100 to apply for personal information and services such as the name, address, social security number, etc. of the customer who receives the packet data service, to terminate the service, stop using the service, It stores and processes service state information such as call stop, device change, and number change, and transmits it to the access network authentication server 130 when service state information is changed. Here, the change of the service state information is generally called a transaction.

The user authentication server 160 encrypts data using an encryption key to transmit and receive user authentication and packet data through the Internet 170 when the authenticated access terminal 100 requests a packet data service. A management function of an encryption level and a data collection function for charging at the packet data serving node 140 are performed. That is, user authentication in the user authentication server 160 is performed after terminal authentication is performed in the access network authentication server 130.

Referring to FIG. 1, a process of receiving a packet data service using the access terminal 100 will be briefly described. First, the access terminal 100 creates a session with the access network 110. Here, the session refers to a state in which the access terminal 100 and the access network 110 share protocols and protocol configuration for communicating with each other. When the session is created, the access network 110 transmits information such as MIN and ESN of the access terminal 100 in which the session is generated to the access network authentication server 130 through the LAN 120 or WAN. The access network authentication server 130 authenticates the access terminal 100 using CHAP with the received network access identifier (NAI) information.

After the authentication of the access terminal 100 is completed, if the access terminal 100 and the packet data serving node 140 authenticate using the PPP authentication protocol, the user authentication server 160 authenticates the user of the access terminal 100. Do this. When the user authentication is completed by the user authentication server 160, the PPP connection is completed between the access terminal 100 and the packet data serving node 140. Thereafter, the access terminal 100 can transmit and receive packet data from the Internet 170 through the packet controller 116 and the packet data serving node 140 of the access network 110.

However, the user authentication performed at the current user authentication server 160 uses the same NAI, for example, Username: sktelecom or Username: power017, etc., so that the NAI of the packet data serving node 140 can distinguish the subscribers individually. no method. In other words, if each service subscriber has a different NAI, the user authentication server 160 transmits a session termination message to the packet data serving node 140 to access the terminal 100 and the packet data serving node 140. PPP sessions established in between may be terminated. Here, the session refers to a state in which the access terminal 100 uses a packet data service.

On the other hand, the reason for using the same NAI is that the network interworking system used in the 2nd generation communication system does not support the specification (storage capacity and function) enough to store different NAI of millions of subscribers. . However, the packet data serving node 140 employed while evolving into the third generation communication system also did not solve the disadvantage of subscriber information management because the function of the conventional network interworking system was maintained as it is.

In addition, the HRPD communication system of FIG. 1 has a problem in that a function for managing location information of the access terminal 100 does not exist. Therefore, when a transaction of customer information such as service termination, number change, or suspension of use occurs in the customer information center 150, the session established between the corresponding access terminal 100 and the access network 110 cannot be terminated. . That is, since the access network authentication server 130 that has received the changed customer information from the customer information center 150 does not know the location of the access terminal 100, a certain access network 110 establishes a session with the access terminal 100. The session cannot be terminated because it is not known.

Providing a method and system for processing a service termination, suspension of use, and number change transaction occurring while using a high speed packet data communication service using a home location register that manages location information of a customer using a high speed packet data communication service.

An access network authentication server (AN-AAA) for authenticating, a packet data serving node (PDSN) for transmitting and receiving the packet data with the access network, a customer information center for transmitting transaction information related to the access terminal to the access network authentication server, A user authentication server (AAA) for authenticating a user of the access terminal, a home location register for terminating the session according to the transaction information, and an individual location register for transmitting the session information to the home location register; High-speed packet data communication system for processing transactions connected to each other through WAN The method may include: generating a session between the access terminal and the access network, transmitting information of the session from the access network to a home location register through the individual location register, and registering the transaction; A customer information center transmitting the transaction information to the access network authentication server, wherein the access network authentication server stores the transaction information in the user's database and transmits the transaction information to the home location register. The home location register terminates the session by sending a session termination request message through the individual location register, and the home location register sends the result of the transaction to the customer information center through the access network authentication server. Including transmitting To provide a transaction processing method for high rate packet data communication system according to claim.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

2 is a block diagram schematically illustrating a communication system for high speed packet data communication according to an embodiment of the present invention.

The system block diagram of FIG. 2 is similar to the system block diagram of FIG. 1 described above, but additionally adds a home location register 210 and an individual location register 220 to solve the problem of traction of customer information that has not been solved in a conventional system. Installed.

Referring to FIG. 2 based on the contents described with reference to FIG. 1, the access terminal 100 generates a session with the access network 110 and then authenticates through the access network authentication server 130. In addition, the access terminal 100 terminates the session after receiving a session end message from the access network 110 when a transaction such as termination, call stop / use stop, number change, etc. is generated from the access network 110.

The access network authentication server 130 authenticates the access terminal 100 of the customer who wants to use the packet data service. In addition, when a transaction of customer information occurs from the customer information center 150, the relevant information is reflected in the customer database, and the corresponding message is copied and transmitted to the home location register 210 which will be described later.

The access network authentication server 130 uses an International Mobile Station Identity (IMSI) or a MIN as a callback-ID for the NAI used for authentication of the access terminal 100. The NAI is, for example, IMSI@HRPD.NATE.COM. It can be used in the form of MIN@HRPD.NATE.COM. In addition, the password used for authentication of the access terminal 100 can use the ESN of the access terminal 100. Here, the IMSI is a number including a country code (MCC), a mobile network code (MNC) and a mobile identification number (MIN). Taking SK Telecom in Korea as an example, the country code is 450 and the area code is 03, so the IMSI is 450-03-xxx-xxx-xxxx. In other words, IMSI is necessary to use overseas communication service, and MIN is sufficient when using domestic communication service. ESN refers to a 32-bit serial number assigned to a mobile station device to advantageously identify the mobile station device.

The home location register 210 has an interworking function with the access network authentication server 130 and the individual location register 220 to be described later. In more detail, the home location register 210 receives the transaction information of the access terminal 100 from the access network authentication server 130 and transmits the processing result of the received transaction to the access network authentication server 130. . Also, the newly generated session information and the session information transmitted between the individual location registers 220 are received by the A13 Session Information Trasnfer from the individual location register 220.

A13 is a term standardized in "Inter-Operability Specification for High Rate Packet Data Access Network Interfaces" under discussion by 3GPP2, and refers to an interface between multiple access networks in the HPRD communication system described in FIG. However, A13 according to an embodiment of the present invention refers to an interface between individual location registers managing a plurality of access networks in a broader sense. That is, A13 session information transmission according to an embodiment of the present invention refers to a case in which a specific access network managed by a specific individual location register and a specific access terminal where a session is created move to an arbitrary access network managed by another individual location register. .

The individual location register 220 has a linkage function with the home location register 210. The individual location register 220 transmits this session information to the home location register 210 in the case of new generation of session information and transmission of session information by A13 session information transmission. In addition, the individual location register 220 has a function of designating a home location register 210 to transmit session information generated for each MIN or IMSI of the access terminal 100. That is, the individual location register 220 stores information of the home location register 210 corresponding to the MIN or IMSI of each of the access terminals 100.

In addition, the home location register 210 according to an embodiment of the present invention may be dually interoperated with a primary home location register and a secondary home location register, and a failure occurs in the primary home location register. If there is no response, it may be desirable to be able to work with the secondary home location register.

In addition, the message transmitted between the home location register 210 and the individual location register 220 uses the User Datagram Protocol (UDP), which is an Internet standard transport protocol capable of transmitting and receiving data at high speed.

3 is a flowchart illustrating a process in which session information generated after a session is created by an access terminal according to an embodiment of the present invention is registered in a home location register.

As shown in FIG. 3, in the process of registering session information generated by an access terminal in a home location register according to an embodiment of the present invention, a customer who applies for a packet data service requests a packet data service to an access terminal. If a session is created between the access terminal and the access network (S300).

On the other hand, the new session creation here also includes a case where a session is created due to the A13 session information transmission failure described in FIG. 4.

The access network in which the session is created transmits a CHAP request message to the corresponding access terminal for authentication of the access terminal (S302). The access terminal sends a CHAP response message to the access network (S304), thereby completing the authentication of the terminal. Here, since terminal authentication using CHAP is well known to those skilled in the art by a standardized method in 3GPP2, a detailed description thereof will be omitted.

When the access network sends an update request message (General-Update-Req) to the individual location registrar (S306), the individual location registrar records information about the created session. When the individual location register sends an update request message (General-Update-Req) to the home location register (S308), the home location register generates session information for the corresponding access terminal. That is, in the update request message (General-Update-Req) transmitted at each step, information about the corresponding access terminal and the session is recorded.

The home location register generates session information for the corresponding access terminal and transmits an update response message (General-Update-Res) to the individual location register (S310). The individual location register receiving the update response message (General-Update-Res) sends the update response message (General-Update-Res) to the corresponding access network (S312). The session information generated between the specific access terminal and the specific access network is shown. The process of registering with the home location register ends.

As described above, according to the process described with reference to FIG. 3, when a session is created between the access terminal and the access network managed by the individual location register, the generated session information is stored in the home location register through the individual location register. Therefore, when the access terminal moves to another access network managed by the same individual location register, the home location register may determine the location of the access terminal.

4 is a flowchart illustrating a process in which session information transmitted to a target individual location register by A13 session information transmission is registered in a home location register according to an embodiment of the present invention.

Referring to FIG. 4, when the access network managed by the source individual location register and the access terminal in which the session is created move to another access network managed by the target individual location register, the control station transfers the previous unicast access. A UATI allocation request message (UATI-Allocate-Req) including the terminal identifier information is transmitted to the target individual location register (S400).

Here, the source individual location register refers to the individual location register where the access terminal was originally located between the two individual location registers, and the target individual location register refers to another individual location register that manages the access network to which the access terminal has moved.

In addition, UATI is generated by an individual location register as a single access terminal identifier for identifying an access terminal on Air standardized by 3GPP2. That is, over the air, UATI is used as an access terminal identifier, and MIN or IMSI is used as an access terminal identifier in a wired network. In the individual location register and the home location register according to the embodiment of the present invention, mapping information of UATI and MIN or IMSI is stored so that the allocated UATI can be found using MIN or IMSI of the access terminal. Of course, you can also use UATI to find the MIN or IMSI of the access terminal.

The target individual location register allocates a new UATI and transmits a UATI allocation response message (UATI-Allocate-Res) including the newly allocated UATI information to the control station (S402). Upon receiving the UATI assignment response message, the control station transmits a UATI completion request message (UATI-Complete-Req) including the previous UATI information to the target individual location register (S404).

The target individual location register transmits an A13 session information request message (A13 Session-Info-Req) to request session information about the corresponding access terminal to the source individual location register (S406). After receiving the A13 session information request message from the target individual location register, the source individual location register transmits an A13 session information response message (A13 Session-Info-Res) including session information of the corresponding access terminal (S408). The target individual location register sends a UATI complete response message (UATI-Complete-Res) to the control station in response to step S404 (S410).

The target individual location register, which has received the session information of the corresponding access terminal from the source individual location register, transmits an update request message (General-Update-Res) including the received session information to the home location register (S412). The home location register stores session information received from the target individual location register. If the previous session information of the corresponding access terminal is stored in the home location register, an update response message indicating that the new session information received is overwritten with the previous session information and updated with the target individual location register. -Update-Res) is transmitted (S414). The target individual location register transmits an A13 session information confirmation message (A13 Session-Info-Conf) indicating that the A13 session information transmission was successful (S416).

As described above, according to the process described with reference to FIG. 4, even when the access terminal moves to an access network managed by another individual location register, information of the last individual location register in which the session of the access terminal is created is always transmitted to and stored in the home location register. Thus, even if the access terminal moves to an access network managed by another individual location registrar, the home location register can determine the location of the access terminal.

5 is a flowchart illustrating a process of canceling a packet data service in an HRPD communication system according to an embodiment of the present invention.

When the customer who used the packet data service of the HRPD communication system requests service cancellation from the agency of the corresponding carrier, a message about the service termination of the customer is transmitted to the customer information center that manages the customer information collectively. The customer information center transmits a service cancellation message including the MIN of the customer who applied for service termination to the access network authentication server (S500).

Upon receiving the service termination message, the access network authentication server transmits the same service termination message to the home location register (S502). The home location register receiving the service termination message deletes the session information of the customer who applied for service termination, and uses the MIN included in the service termination message and uses the mapping information between the MIN and UATI stored in the corresponding access terminal. The UATI assigned to the UATI is included in the session termination request message (Session-Close-Req) and transmitted to the individual location register (S503).

Here, the individual location register is an individual location register that manages the access network in which the access terminal that has terminated the service finally creates and maintains a session. That is, it refers to a target individual location register that manages the session originally created by the access terminal described with reference to FIGS. 3 and 4 or receives session information of the corresponding access terminal from the source individual location register by transmitting the A13 session information.

Receiving the session end request message from the home location register, the individual location register deletes the session information of the customer who applied for service termination using the received UATI, and generates the session end request message again using the received session end command message. Then, it transmits to the access network in which the session with the access terminal is maintained (S504). Upon receiving the session termination request message from the individual location register, the access network transmits a session termination message (Session-Close) to the corresponding access terminal (S506). Upon receiving the session end message, the access terminal terminates the session with the access network and transmits the session end message to the access network again, indicating that the session is completed (S508).

Upon receiving the session termination message from the access terminal, the access network transmits a session termination response message (Session-Close-Reply) indicating that the session is terminated to the individual location register (S510). The individual location register receiving the session end response message from the access network regenerates the session end response message and transmits the session end response message to the home location register (S512). A service cancellation acknowledgment (Ack) message indicating that the termination request is properly processed is transmitted to the access network authentication server (S514). The access network authentication server transmits the service termination recognition message received from the home location register to the customer information center (S516).

6 is a flowchart illustrating a process of stopping transmission / use of a packet data service in an HRPD communication system according to an exemplary embodiment of the present invention.

When the customer who used the packet data service of the HRPD communication system applies for transmission / suspension at the agency of the corresponding communication company, a message about the transmission / suspension of the customer is transmitted to the customer information center. The customer information center transmits an outgoing / outage message including the MIN of the customer who applied for outgoing / outage to the access network authentication server (S600).

The access network authentication server receiving the origination / suspension message from the customer information center sets the service origination / suspension attribute on the service status information data of the corresponding customer by using the received MIN, and sends the origination / suspension to the home location register. The usage stop message is transmitted (S602). The home location register receiving the origination / suspension message from the access network authentication server deletes the session information of the customer who applied for origination / suspension and uses the MIN information included in the received origination / suspension message. The UATI assigned to is found, and the UATI is included in the session close request message (Session-Close-Req) and transmitted to the individual location register (S603).

Since the process from step S604 to step S612 shown in FIG. 6 is the same as the process from step S504 to step S512 described with reference to FIG. 5, a detailed description thereof will be omitted.

In step S612, the home location register, which has received the session end response message, transmits an origination / use stop recognition message indicating that the origination / use stop of the service has been properly processed to the access network authentication server (S614). The access network authentication server transmits the received transmission / stoppage recognition message to the customer information center (S616).

When the origination / use stop of the service is performed through the process described with reference to FIG. 6, the session created between the access terminal applying for the origination / use stop and the access network ends. In addition, if the user wants to use the packet data service using the same access terminal after the end of the session, since the use / call-stop property of the service is set in the data related to the access terminal in the access network authentication server, the authentication is not performed and thus the packet data service is not performed. The service will not be available. That is, the access network authentication server transmits an access-reject message to the access network requesting creation of a session with the access terminal that has been suspended / disabled, thereby making it impossible to create a session with the access terminal.

7 is a flowchart illustrating a process of changing the number of an access terminal of a packet data service in an HRPD communication system according to an embodiment of the present invention.

When the customer who used the packet data service of the HRPD communication system requests the change of the access terminal number from the agency of the corresponding carrier, a message about the change of the number of the customer is transmitted to the customer information center. The customer information center transmits a number change message including the existing MIN of the customer who applied for the number change and the newly created MIN to the access network authentication server (S700).

Upon receiving the number change message from the customer information center, the access network authentication server deletes the information of the customer corresponding to the received MIN. The access network authentication server creates a new callback-ID with the NAI using the changed new MIN and stores the changed MIN together with the changed MIN. Of course, if the access terminal is replaced when the customer's access terminal is changed, the access network authentication server will store the replaced ESN as a new password.

The access network authentication server transmits the number change message received from the customer information center to the home location register (S702). The home location register, which receives the number change message from the access network authentication server, deletes the session information of the customer who applied for the number change, and uses the existing MIN information included in the received number change message and is assigned to the corresponding access terminal. The UATI is found and included in the session close request message (Session-Close-Req) and transmitted to the individual location register (S703).

Since the process from step S704 to step S712 shown in FIG. 7 is the same as the process from step S504 and step S604 described in FIGS. 5 and 6 to step S512 and step S612, a detailed description thereof will be omitted.

The home location register, which has received the session end response message in step S712, transmits a number change recognition message indicating that the number change of the access terminal has been properly processed to the access network authentication server (S714). The access network authentication server transmits the received number change recognition message to the customer information center (S716).

When the number change procedure of the access terminal is performed through the process described with reference to FIG. 7, the session created between the access terminal applying for the number change and the access network ends. In addition, if the user wants to use the packet data service using the existing access terminal number after the end of the session, since the data related to the existing number does not exist in the access network authentication server, the packet data service cannot be used because authentication is not performed. . That is, the access network authentication server transmits an access-reject message to the access network requesting to create a session with the access terminal using the existing number, thereby making it impossible to create a session with the access terminal.

Meanwhile, since the protocol format of a message transmitted between devices in FIGS. 3 to 7 is defined in "Inter-Operability Specification for High Rate Packet Data Access Network Interfaces" (3GPP2 A.S0007-0 Version 2.0) Detailed description thereof will be omitted.

It will be appreciated by those skilled in the art that the present invention is not limited to the above embodiments, and that various modifications and changes can be made without departing from the spirit of the present invention.

As described above, in the conventional HRPD communication system, there is no function for managing the location of the terminal, so there is no way to terminate the generated session when a transaction of the packet data service occurs. However, according to the present invention, even if the terminal moves to another access network, the individual location register that manages the access network transmits the information and session information of the terminal to the home location register so that the home location register always has a session through the individual location register. The location of the generated terminal can be identified.

Accordingly, in the HRPD communication system according to the present invention, when a transaction occurs, the transaction information may be stored in the home location register and the individual location register, and the transaction may be processed by transmitting a session termination command to the specific access network where the terminal is located. .
