Abstract

PURPOSE: A device for controlling an intelligent network subscriber data call using an AAA(Authentication Authorization Accounting) server with a dual connection list memory structure is provided to use a memory structure of a dual connection list using arrays as a temporary storage of an AAA server necessary for interworking a PDSN(Packet Data Service Node) with an SCP(Service Control Point) server, thereby reducing processing time and improving performance of the AAA server. CONSTITUTION: A PDSN(100) outputs a data call connection request message(Subsinfo_Req) including calling subscriber number information for an intelligent network subscriber, inputs a data call connection response message(Subsinfo_Res) for the data call connection request message(Subsinfo_Req), and interfaces the data call connection response message(Subsinfo_Res) to a wireless access network. An AAA server(200) stores the data call connection request message(Subsinfo_Req) in a temporary DB with a dual connection list structure, outputs an information request message(Data_AI_RQ), inputs an information response message(Data_AI_RP) from a subscriber, configures the data call connection response message(Subsinfo_Res), and outputs the message(Subsinfo_Res) to the PDSN(100). An SCP server(300) inputs the information request message(Data_AI_RQ), and outputs the information response message(Data_AI_RP) to the AAA server(200).

200: Authentication Authorization Accounting (AAA) server

300: Service Control Point (SCP) Server

Hereinafter, an intelligent network subscriber data call control apparatus and method using an AAA server having a dual linked list memory structure according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a functional block diagram of an intelligent network subscriber data call control apparatus using an AAA server having a dual linked list memory structure according to an embodiment of the present invention, and has a dual linked list memory structure according to an embodiment of the present invention. An intelligent network subscriber data call control apparatus using an AAA server is composed of a packet data service node 100, an AAA server 200, and an SCP server 300.

The packet data service node (PDSN) 100 serves as an interface between two networks between a radio access network and a data core network including a base station, a control station, and a switch. Outputs a data call connection request message (Subsinfo_Req) including the outgoing subscriber number information for the AAA server 200, while a data call connection response message (Subsinfo_Res) for the data call connection request message from the AAA server 200. At the same time as receiving the input and the data call connection response message serves to interface with the wireless access network.

In addition, the AAA server 200 is a server system that performs subscriber authentication, authorization, and billing processing. The AAA server 200 uses an array of data call connection request messages (Subsinfo_Req) received from the packet data service node 100. After storing the information for configuring the data call response message (Subsinfo_Res) in a temporary database of the connection list structure, and outputs the information request message (Data_AI_RQ) for the subscriber to the SCP server 300, the SCP server 300 Receives the information response message (Data_AI_RP) of the subscriber for the information request message from the network and simultaneously configures the data call connection response message (Subsinfo_Res) with the information stored in the temporary database and outputs it to the packet data service node 100. It plays a role.

Here, the AAA server 200 uses a temporary database of a dual linked list memory structure using an array without using a conventional Oracle database.

In addition, the SCP server 300 receives the information request message (Data_AI_RQ) for the subscriber from the AAA server 200 and at the same time the information response message (Data_AI_RP) containing the information of the corresponding subscriber corresponding to the AAA It serves to output to the server (200).

In addition, Fig. 3 shows a reference diagram for explaining the initialization of a dual linked list using an arrangement according to the present invention, and Fig. 4 shows a reference diagram for explaining the insertion of a double linked list using an arrangement according to the present invention. 5 is a reference diagram shown to illustrate the deletion of a dual linked list using an arrangement in accordance with the present invention.

Then, an intelligent network subscriber data call using an AAA server having a dual linked list memory structure according to an embodiment of the present invention using an AAA server having a dual linked list memory structure having the above configuration. The control method will be described.

2 is an operation flowchart illustrating an intelligent network subscriber data call control method using an AAA server having a dual linked list memory structure according to an embodiment of the present invention.

First, the AAA server 200 receives a data call connection request message (Subsinfo_Req) including the outgoing subscriber number information for the intelligent network subscriber from the packet data service node 100 (S1).

Thereafter, the AAA server 200 stores the data call connection request message Subsinfo_Req received from the packet data service node 100 in a temporary database DB having a dual connection list structure using an array (S2). .

Subsequently, the AAA server 200 outputs an information request message (Data_AI_RQ) for the subscriber to the SCP server 300 (S3).

Thereafter, the AAA server 200 receives an information response message (Data_AI_RP) of the corresponding subscriber corresponding to the information request message from the SCP server 300 (S4).

Subsequently, the AAA server 200 performs a processing operation using the information response message (Data_AI_RP) including the corresponding subscriber information received from the SCP server 300 and the information stored in the temporary database and at the same time the corresponding data call. After configuring the connection response message (Subsinfo_Res) and outputs to the packet data service node 100 (S5).

3, 4 and 5 further illustrate the initialization of a list using a temporary database of a dual linked list memory structure using an arrangement according to the present invention, the insertion of a list (index 0, 1), and the deletion of a list (index 1). A reference diagram is shown to illustrate, and this technique is a technique that can be universally applied to a server requiring a small amount of data information management.

According to the apparatus and method for intelligent network subscriber data call control using an AAA server having a dual linked list memory structure according to the present invention as described above, an AAA having a double linked list memory structure using an arrangement in the data call setup function of an intelligent network subscriber is provided. By making it possible to process the data call of the intelligent network subscribers quickly using the server, the processing time of the insertion, search, and deletion of the information required for the data call processing is greatly reduced, which speeds up the processing speed of the AAA server. As a result, the performance of the AAA server is improved.

In addition, since the AAA server uses a dual linked list memory structure using an array rather than memory allocation, only one search time is required when deleting, thereby further improving the performance of the AAA server.
