Abstract

The present invention generally relates to an Authentication, Authorization, and Accounting (AAA) server structure, and more particularly to an AAA server structure that utilizes threads. The AAA server of the present invention comprises: a Subscriber (SUBS) creation thread which, upon receiving a data call connection request message from an intelligent network server via the PSDN, constitutes a data call connection response message with information stored in the temporary database and then transmits the data call connection response message to the PDSN and simultaneously removes the information of the temporary database by locking and unlocking a Mutual exclusion object (Mutex); and a SUBS main thread, which determines through the SUBS creation thread whether the request message is for a subscriber of the intelligent network, and if it is for the subscriber of the intelligent network, locks the Mutex to synchronize a source to the temporary database that has doubly linked list structure using an array, and then transmits a message requesting an information on the subscriber of the intelligent network after storing the information for constituting the data call connection response message and unlocking the Mutex. In order to establish a data call for a subscriber of the intelligent network in a CDMA I X system, the AAA sever is responsible for cooperating with a Service Control Point (SCP) server and a Packet Data Serving Node (PDSN). The AAA server of the present invention utilizes threads to constitute a dual process structure, which may increase the processing speed and throughput by dividing the data call-establishing process, which is conventionally one process, into two processes.

Description

AAA SERVER STRUCTURE WITH THREADS
TECHNICAL FIELD The present invention generally relates to an Authentication, Authorization, and Accounting (AAA) server structure, and more particularly to an AAA server structure, which utilizes threads to constitute a dual process structure.
BACKGROUND ART hi a CDMA IX system, the AAA server is responsible for establishing a data call for a subscriber, authorizing a subscriber, and accounting. The AAA server receives from a Packet Data Serving Node (PDSN) a message requesting a data call connection for a subscriber. It then cooperates with a Service Control Point (SCP) server to transmit a response message to the PDSN. In the conventional AAA server, the process of receiving and transmitting messages is erformed in a single process structure. Accordingly, the increase in input and output traffics results in a lower processing speed and degraded performance.
DISCLOSURE OF THE INVENTION Therefore, the object of the present invention is to solve the above problems.
In particular, the object of the present invention is to provide an AAA server structure, which utilizes threads to constitute a dual process structure for processing a data call, thereby improving the processing speed and performance. In order to achieve the above objects, the present invention provides an AAA server structure, which interacts with a Packet Data Serving Node (PDSN) and a Service Control Point (SCP) server, comprising: a temporary database; a Subscriber (SUBS) creation thread, wherein upon receiving a data call connection request message from an intelligent network server via the PSDN, the SUBS creation thread constitutes a data call connection response message with information stored in the temporary database, and then transmits the data call connection response message to the PDSN and simultaneously removes the information of the temporary database by locking and unlocking a Mutual exclusion object (Mutex); and a SUBS main thread, wherein the SUBS main thread determines through the
SUBS creation thread whether the request message is for a subscriber of the intelligent network, and if it is for the subscriber of the intelligent network, the SUBS main thread locks the Mutex to synchronize a source to the temporary database that has doubly linked list structure using an array, and then transmits a message requesting an information on the subscriber of the intelligent network after storing the information for constituting the data call connection response message and unlocking the Mutex.
BRIEF DESCRIPTION OF DRAWINGS Fig. 1 is a functional block diagram of the AAA server structure utilizing threads according to one embodiment of the present invention.
BEST MODE FOR CARRYING OUT THE INVENTION ' Hereinafter, an AAA server structure utilizing threads according to one embodiment of the present invention will be described in detail with reference to the accompanying drawing. Fig. 1 is a functional block diagram of the AAA server structure utilizing threads according to one embodiment of the present invention. The AAA server structure comprises SUBS creation thread 100, SUBS main thread 200, and temporary database 300. SUBS creation thread 100 performs the following operations: upon receiving a data call connection request message from an intelligent network server via the PSDN, constitutes a data call connection response message with information stored in temporary database 300; transmits the data call connection response message to the PDSN; and removes the information of the temporary database by locking and unlocking a Mutual exclusion object (Mutex). Meanwhile, SUBS main thread 200 determines through SUBS creation thread 100 whether the request message is for a subscriber of the intelligent network. If the request message is for the subscriber of the intelligent network, SUBS main thread 200 performs the following operations: locks the Mutex to synchronize a source to temporary database 300 that has doubly linked list structure using an array; stores the information for constituting the data call connection response message and unlocking the Mutex; and transmits a message requesting an information on the subscriber of the intelligent network. The operations of the AAA server having a structure with threads as described above will now be described with reference to Fig. 1. The AAA server cooperates with the PDSN and the SCP server to establish a data call connection. Initially, upon receiving a data call connection request message from an intelligent network server via the PSDN, SUBS creation thread 100 constitutes a data call connection response message with information stored in the temporary database 300. SUBS creation thread 100 then transmits the data call connection response message to the PDSN and simultaneously removes the information of the temporary database 300 by locking and unlocking a Mutual exclusion object (Mutex). SUBS creation thread 100 repeats the tasks above independently of SUBS main thread 200. In the meantime, SUBS main thread 200 determines through SUBS creation thread 100 whether the request message is for a subscriber of the intelligent network. If it is for the subscriber of the intelligent network, SUBS main thread 200 locks the Mutex to synchronize a source to the temporary database that has doubly linked list structure using an array. It then stores the information for constituting the data call connection response message. SUBS main thread 200 then unlocks the Mutex and transmits a message requesting information on the subscriber of the intelligent network.
INDUSTRIAL APPLICABILITY As described above, the AAA servers of the present invention is responsible for cooperating with a Service Control Point (SCP) server and a Packet Data Serving Node (PDSN) to establish a data call for a subscriber of the intelligent network in a CDMA IX system. In particular, the AAA server of the present invention utilizes threads to constitute a dual process structure, which may increase the processing speed and throughput by dividing the data call-establishing process, which is conventionally a one process, into two processes. Therefore, the AAA server structure of the present invention may have improved performance. The present invention is described with reference to the preferred embodiment and the drawing. However, such description is not intended to limit the present invention to the constitution disclosed herein. It should also be understood that a person skilled in the art is capable of using a variety of modifications and other embodiments equal to the present invention. Therefore, only the appended claim is intended to limit the present invention.
