Description

TECHNICAL FIELD The present invention relates to a client-server communication system, a client-server communication system, and a client-server communication system.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an intelligent network service system to which a client-server communication structure is applied, and more particularly to a intelligent network service system in which a plurality of request messages are simultaneously transmitted from a customer management system, The present invention relates to a client management request distribution processing method in an intelligent network service system of a client-server communication structure in which a plurality of request messages are distributed in an intelligent network service management system (SMS) when transmitted to a service management system.

In general, the intelligent network service is a newly introduced service to satisfy the requirement level of the communication user, and it is possible to add new technology to the existing communication network and to add various new functions rapidly in terms of service, Function. The intelligent network service system is a system for providing such intelligent network service.

Generally, a computer (hardware or software) that collectively manages and provides information or resources is called a server, and hardware or software that requests information from a server and uses resources is called a client. As a result, a method of effectively executing an application program is called a client-server model.

This client-server model is applied to a customer management system, an intelligent network service management system, and a service control system, and its block configuration is shown in FIG.

As shown in the figure, a customer service billing system (CSBS) 10 for integrally managing the information of the intelligent network service subscribers; An intelligent network service management system (SMS) 20 for managing a database used in the service control systems 30 and 31 according to the request of the customer management system (CSBS) 10; And a service control point (SCP) 30 that has a service control logic required for performing the intelligent network service and a database having subscriber data and performs overall service control using the database.

The management request processing operation of the intelligent network service subscriber of the general intelligent network service system will be described. The customer management system (CSBS) 10 integrally manages the information of the intelligent network service subscribers. That is, if a new intelligent network service subscriber is subscribed, the customer management system (CSBS) 10 sends an SMS message to the intelligent network service management system (SMS) 30 to generate information on the new subscriber in the database of the service control system (20). ≪ / RTI > When the subscriber has canceled the subscription, the customer management system 10 sends a deletion request message to the intelligent network service management system 20 to delete the information of the subscriber stored and managed in the service control system (SCP) . In addition, the customer management system 10 requests the intelligent network service management system 20 to change or inquire the information of the intelligent network service subscriber.

The intelligent network service management system 20 manages and manages a database that the service control system 30 uses for service control. This intelligent network service management system 20 operates as a server for the customer management system 10 and acts as a client for the service control system 30. [ Therefore, when a subscriber information management request such as creation, deletion, change, or inquiry of subscriber information is requested from the customer management system 10, the intelligent network service management system 20 receives the request and sends it to the service control system 30 Requests the service requested.

When the subscriber information management request message is received from the customer management system 10 in the CSBS Interface Block (CSIB) (not shown in FIG. 1) of the intelligent network service management system 20, To a service control system (30). Then, a subscriber information management request message is transmitted to the service control system 30 through this session to request subscriber information management.

In general, a message is transmitted and received between the customer management system (CSBS) 10 of the intelligent network service system and the intelligent network service management system 20 through eight active / standby sessions. A session is a separate path through which messages can be sent and received between processes.

In this way, there is a request through a maximum of 16 sessions between the customer management system 10 and the intelligent network service management system 20, and there is one process for handling requests through the plurality of sessions, You must. However, if a request through a session requires a lot of system resources or a request that requires a lot of processing time, it will not be able to respond to other requests sent through another session while processing this request.

If the response processing operation is performed in one process between the client management system (CSBS) of the general intelligent network service system and the intelligent network service management system (SMS), if the processing time for the arbitrary request takes a long time, There is a problem that it takes a lot of service processing time and a lot of burden is imposed on the process of performing the response processing.

In addition, since the service processing time is long, it is difficult to provide the service quickly.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a system and method for simultaneously receiving a plurality of request messages from a Customer Service Billing System (CSBS) When the message is transmitted to the service management system (SMS) of the server, the intelligent network service management system (SMS) distributes the plurality of request messages in order to speed up the message processing speed and distribute the load according to the message processing And to provide a client management request distribution processing method in an intelligent network service system of a client-server communication structure.

According to another aspect of the present invention, there is provided a client management request distribution processing method in an intelligent network service system of a client-

Hereinafter, the client management request distribution processing method in the intelligent network service system of the client-server communication structure according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a flowchart showing a method for distributing a customer management request according to the present invention.

As shown therein, a first step ST11 of generating a plurality of child processes; After the first step ST11, a message is read from a message queue buffering a message from the customer management system 10, and if the read message is a subscriber information management request message, A second step (ST12-ST14) for finding a valid session to transmit this message to the service control system 30 during a formal session; And a third step (ST15) of transmitting the subscriber information management request message through the found valid session.

The method of forming a session of the child process in the second step ST12-ST14 comprises the steps of: initializing a socket, which is a network interface, for each inter-process communication service generated in the first step ST11 (ST21); If there is a connection request from the customer management system 10, the child process receiving the connection request among the plurality of generated child processes accepts the connection and requests connection to the service control system 30 again (ST22, ST23 )Wow; (ST24) of establishing a session between the customer management system (10) and the service control system (30) when receiving a connection acceptance from the service control system (30) receiving the connection request.

The third step (ST15) includes the step (ST25) of checking the received signal by the child process selected in the second step (ST12-ST14); If the received signal is a request message transmitted from the customer management system 10, transmitting the request message to the service control system 30 through a session (ST26, ST27); If the received signal is a response message transmitted from the service control system 30, transmitting the response message to the customer management system 10 (ST28, ST29).

The client management request distribution processing method in the intelligent network service system of the client-server communication structure according to the present invention will now be described in detail.

First, the CSBS Interface Block (CSIB) of the intelligent network service management system 20 creates a plurality of child processes in a thread-by-thread manner when initialization is performed (ST11). At this time, the number of child processes to be created is 40, which is formed between the customer management system 10 and the intelligent network service management system 20, and manages the sessions in one-to-one correspondence with one session for 16 sessions for transmitting and receiving messages A sufficient number is enough. A thread is a unit of a program that is treated as a multi-task function. Accordingly, the conventional IN service management system 20 operates to manage a plurality of sessions in one process. However, the present invention generates a plurality of child processes in the one process and manages each session in each child process do.

When a plurality of child processes are created, each child process initializes a network interface for inter-process communication service. Since the client-server model operates between the customer management system 10 and the intelligent network service management system 20 and the service control system 30, the intelligent network service management system 20 can perform communication between the processes in the client- A socket is used as a network interface for providing a service, and thus a child process initializes a socket (ST21). This socket basically provides TCP / IP (Transmission Control Protocol / Internet Protocol) and UDP (User Datagram Protocol) as lower layer protocols. TCP / IP is a connection-oriented protocol that establishes an interconnect between end-users and communicates data over the connection. UDP is a connectionless oriented protocol that communicates data with no interconnection between end users. In the intelligent network service system, TCP / IP is used to improve the reliability of data transmission. Therefore, the connection between the client and the server process is set up prior to data transfer.

The client management system 10 attempts to connect to the intelligent network service management system 20, which is a server, in order to request subscriber information management. That is, the client management system 10 tries to make a TCP / IP connection request. When one child process among a plurality of child processes generated in the CSIB of the intelligent network service management system 20 receives a connection request from the customer management system 10 (ST22), the child process accepts the connection. The child process sets the connection point between the customer management system 10 and the intelligent network service management system 20 to cs_sfd0. Then, the child process operates as a client and attempts a connection request to the service control system 30 (ST23). Then, when the service control system 30 accepts the connection, the child process sets the connection point between the intelligent network service management system 20 and the service control system 30 to scp_sfd0.

The intelligent network service management system 20 manages connection points between a connection point with the customer management system 10 and the service control system 30 in the form of a table as shown in Table 1 below, As shown in FIG.

child process 0 One 2 ... MAX_ID Connection point with customer management system cs_sfd0 cs_sfd1 cs_sfd2 ... cs_sfdn Connection point with service control system scp_sfd0 scp_sfd1 scp_sfd2 ... scp_sfdn

In Table 1, MAX_ID indicates the maximum number of processes.

Thus, one session is formed between the customer management system 10, the intelligent network service management system 20, and the service control system 30. The child process then periodically checks these connection points (cs_sfd0, scp_sfd0) to see if there are any messages that they need to process.

Then, when the customer management system 10 requests information inquiry of the subscriber stored in the database of the service control system 30, the inquiry request message is requested to the intelligent network service management system 20.

Meanwhile, the parent process of the CSIB reads a message from a message queue that buffers a message transmitted from the customer management system 10. And transmits the read message to the child process that created the session.

The child process that has transmitted the message from the parent process checks this received signal (ST25). If the request message is transmitted from the customer management system 10 as a result of the inspection, the request message is transmitted to the service control system 30 through the formed session (ST26, ST27). Thus, the intelligent network service management system 20 requests the service control system 30 to inquire subscriber information.

When the request message for generating the subscriber information is transmitted from the customer management system 10 while the service control system 30 is inquiring the information of the subscriber according to the request, the intelligent network service management system 20 transmits the subscriber's information to the other child process So as to process this new request message. However, in the conventional message processing method, the message processing time is delayed because the processing for the new generated message can not be performed until the service for the inquiry message is terminated.

When the subscriber information inquiry service is completed, the service control system 30 transmits a response message to the child process of the intelligent network service management system 20, and the child process transmits the response message to the customer management system 10 (ST28, ST29).

By creating a plurality of child processes in this manner and distributing the request message of the client management system 10, which is a one-to-one correspondence with the child session, the request message processing time is shortened and the load given to one process is reduced do.

As described above, in the intelligent network service system of the client-server communication structure according to the present invention, the client management request distribution processing method includes a plurality of child processes in the intelligent network service management system (SMS) And a request message is processed in a one-to-one correspondence with the session between the child process and the customer service management system (CSBS), so that when a plurality of request messages are simultaneously transmitted from the customer management system, So that message processing can be speeded up.

In addition, by distributing the request message of the client in each child process, the load of the message processing is distributed to each child process, thereby improving the stability of the system.
