Abstract

A service limited subscriber management method in a packet data network is provided to be capable of storing information on a subscriber whose service limit is exceeded, in an AN-AAA(Authentication, Authorization, and Accounting) server and a home DLR(Data Location Register), and of preventing a call processing procedure from being progressed up to an SCP(Service Control Point) when the subscriber attempts a call, thus network loads are reduced. An SCP transmits information on a subscriber whose service limit is exceeded, to an AN-AAA server(S101). The AN-AAA server stores the transmitted information on the subscriber in a DB, and transmits the stored information on the subscriber to a home DLR(S102-S104). The home DLR updates an exceeded service limit information storage field of the corresponding subscriber(S105). The home DLR transmits a session information deletion command to a DLR, so that a session of the subscriber is deleted(S106-S108).

The present invention relates to a method for managing limit subscribers in a packet data network. More particularly, the present invention relates to an authentication server (AN-AAA) and a home data location register (HomeDLR) for expired subscriber information in a packet data network such as an EV-DO network. The present invention relates to a limit subscriber management method in a packet data network, which is stored and prevents a network load due to an unnecessary call processing procedure for a limit expired subscriber.

Currently, limit expiration information of limit subscribers in the packet data network is included only in the service control point (SCP), and data location register (DLR), home data location register (HomeDLR), and authentication server (AN-AAA) have expired subscriber information. Since the call processing procedure proceeds to the service control point (SCP), the load is increased on the data location register (DLR), the home data location register (HomeDLR), and the service control point (SCP).

That is, as shown in Figure 1, when the terminal attempts to call (S01), when the access network controller (ANC) requests the call attempt resource to the data location register (DLR) (S02), conventionally the data location register After the DLR responds (S03), it requests a limit subscriber's call processing to the service control point (SCP) through the home data location register (HomeDLR) (S04).

Accordingly, the service control point SCP recognizes that the limit of the corresponding subscriber has expired, and transmits call failure information due to the limit expiration to the data location register DLR through the home data location register HomeDLR (S05).

As described above, according to the conventional limit subscriber call processing process, whenever a subscriber whose limit is expired attempts a packet data call, a call processing request message (Origination Request) must be transmitted to the service control point (SCP). There is a problem in that the network load is increased because only the information indicating that the service control point (SCP) has expired each time is transmitted to the data location register (DLR).

Accordingly, the present invention is to solve the above-mentioned disadvantages and problems of the prior art, and stores the information of the expired subscriber in the authentication server and the home data location register, the service control point when the limit expired subscriber attempts to call SUMMARY OF THE INVENTION An object of the present invention is to provide a method for managing subscribers in a packet data network that can reduce network load by preventing a call processing procedure.

The above object of the present invention is a data control point (DLR), a home data location register (HomeDLR), an authentication server (AN-AAA) for storing subscriber profile information and authenticating subscribers and a service control point for managing limit information of limit subscribers. A limit subscriber management method in a packet data network including (SCP), comprising: a step A of the service control point (SCP) transmitting information of a subscriber whose limit has expired to the authentication server (AN-AAA); A step (B) of the authentication server (AN-AAA) storing the expired subscriber information in a database and transmitting the expired subscriber information to a home data location register (HomeDLR); Step C, wherein the home data location register HomeDLR updates the limit expiration information storage field of the subscriber; In the packet data network including a limit is achieved by a subscriber management method.

In addition, the above object of the present invention is an access network controller (ANC), data location register (DLR), home data location register (HomeDLR), authentication server (AN-AAA) and limit subscriber for storing subscriber profile information and subscriber authentication A limit subscriber management method in a packet data network including a service control point (SCP) that manages limit information of a service, wherein a call is attempted from a mobile communication terminal, and an access network controller (ANC) calls the data location register (DLR). In response to requesting a challenge resource, the data location register (DLR) requesting a call processing of the subscriber to a home data location register (HomeDLR); Determining, by the home data location registerer (HomeDLR), whether the subscriber is a limit subscriber, and in the case of a limit subscriber, querying the limit expiration information storage field of the subscriber to determine whether the limit has expired; A step C of transmitting, by the home data location register (HomeDLR), a call processing reject message including the limit expiration information to the data location register (DLR) when the limit expired subscriber is determined; In the packet data network including a limit is achieved by a subscriber management method.

Details of the above object and technical configuration of the present invention and the resulting effects thereof will be more clearly understood from the following detailed description based on the accompanying drawings.

First, Figure 2 is a block diagram of a packet data network for explaining the present invention.

As shown, the packet data network (EV-DO) to which the present invention is applied includes an Access Network Transceiver System (ANTS) 11 and an access network controller (ANC) for wireless section communication with the terminal 10. Access Network Controller (12), General ATM Switch Network (GAN), Data Location Register (DLR) 14, Home Data Location Register (DLR), which manages multiple Data Location Registers. 15), a service control point (SCP) 16 and an authentication server (AN-AAA) 17 for limit information management of limit subscribers and limit subscriber call control.

The data location register 14 performs a role of allocating UATIs and attempts to manage mobility of subscribers when attempting a data call of a packet data service (EV-DO) subscriber, and the home data location register 15 includes a plurality of data location registers ( It is connected with 14) and manages location information of EV-DO subscriber.

The authentication server 17 performs an authentication function for the terminal when the terminal is powered on, and the present invention further includes a limit expired subscriber information database for storing information of the expired subscriber.

In the present invention, the service control point 16 transmits the information of the limit expired subscribers to the authentication server 17 periodically or in real time, and the authentication server 17 stores the information in the limit expired subscriber information database, The expired subscriber information is sent back to the home data location register 15 so that the call processing procedure does not proceed to the service control point 16.

The limit subscriber management method in the packet data network of the present invention as described above will be described in detail with reference to FIGS. 3 and 4 as follows.

First, FIG. 3 is a flowchart illustrating a process of processing expired subscriber information in the method of managing a subscriber in accordance with an embodiment of the present invention.

As shown, in the present invention, the service control point 16 transmits the information (table) of the limit subscribers whose limit has expired to the authentication server 17 (S101).

The authentication server 17 stores the received limit expired subscriber information in a database (S102), responds to the service control point 16 (S103), and session information due to limit expiration to the home data location register 15. The delete request message is transmitted (S104).

Next, the home data location register 15 checks the limit expiration information included in the session information deletion request message, updates the limit expiration information in the limit expiration information storage field of the profile information of the subscriber (S105), and the authentication. The server 17 responds with a response (S106).

In addition, the home data location register 15 transmits a session information deletion command to the access network controller 12 through the data location register 14 to delete the session information of the expired subscriber (S107). 14 and the access network controller 12 delete the session information for the corresponding expired subscriber and respond to the home data location register 15 (S108).

Next, FIG. 4 is a flowchart illustrating a process of processing an expired subscriber call of a limit subscriber management method according to an embodiment of the present invention, wherein the home data location register 15 receives limit expired subscriber information by the process shown in FIG. 3. The call processing process in the case of management is shown.

As shown, when the terminal 10 attempts to call (S201), the access network controller 12 requests a call attempt resource (user call related information such as QoS, ANC, ANTS) to the data location register 14 In step S202, the data location register 14 responds to the request (S203), and requests a call process from the home data location register 15 (S204).

The home data location register 15 determines whether the corresponding subscriber is a limit subscriber, and if the subscriber is a limit subscriber, inquires a limit expiration information storage field of profile information of the corresponding subscriber (S205).

As a result of the inquiry, when it is confirmed that the subscriber is a limit expired subscriber, the home data location register 15 does not request the service control point 16 to process a limit subscriber's call, but the limit expires at the data location register 14. The call processing rejection message including the information is transmitted (S206).

Accordingly, the data location register 14 transmits call failure information to the terminal 10 through the access network controller 12 to stop the call progress (S207).

The home data location register 15 also issues a session information deletion command via the data location register 14 to the session information deletion command for the expired subscriber who attempted the call. In step S208, the terminal 10, the access network controller 12, and the data location register 14 perform a session deletion process and respond to the home data location register 15 (S209).

As those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features, the embodiments described above should be understood as illustrative and not restrictive in all aspects.
