Description

Decentralized Processing Method of Customer Management in Intelligent Network Service System of Client-Server Communication Architecture

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intelligent network service system to which a client-server communication structure is applied. In particular, an intelligent network in which a plurality of request messages are simultaneously a server from a customer management system which is a client managing an intelligent network service subscriber. The present invention relates to a method for distributing customer management requests in an intelligent network service system of a client-server communication structure in which an intelligent network service management system (SMS) distributes these multiple request messages when transmitted to the service management system.

In general, the intelligent network service is a newly introduced service to meet the demand level of the communication user, and it is easy to add new technology to the existing communication network, and can quickly add various new functions in terms of service, and standardized network access. It is to provide a function. A system for providing such an intelligent network service is an intelligent network service system.

In general, a computer (hardware or software) that centrally manages and provides information or resources is called a server, and hardware or software that requests information from a server and uses the information or resources is called a client. By their solidarity, the way to run an application program efficiently is called the 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 a block configuration thereof is shown in FIG.

As shown therein, a Customer Service Billing System (CSBS) 10 for integrated management of information of an intelligent network service subscriber; An intelligent network service management system (SMS) 20 for managing a database used in the service control systems 30 and 31 according to a request of the customer management system (CSBS) 10; It is composed of a service control system (SCP) 30 having a database having service control logic and subscriber data necessary for performing an intelligent network service and performing overall service control using the database.

Referring to the management request processing operation of the intelligent network service subscriber of the general intelligent network service system, the customer management system (CSBS) 10 integrates and manages the information of the intelligent network service subscriber. In other words, if a new intelligent network service subscriber is subscribed, the CSMS 10 may generate an intelligent network service management system (SMS) to generate information about the new subscriber in a database of the service control system (SCP) 30. Send the creation request message to (20). When the subscriber is unsubscribed, the customer management system 10 deletes the message of the subscriber to the intelligent network service management system 20 in order to delete the information of the subscriber stored and managed in the service control system (SCP) 30. Send it. In addition, the customer management system 10 requests the intelligent network service management system 20 to change or query information of the intelligent network service subscriber.

The intelligent network service management system 20 operates and manages a database that the service control system 30 uses for service control. The intelligent network service management system 20 operates as a server for the customer management system 10 and as a client for the service control system 30. Therefore, when a subscriber information management request such as creation, deletion, modification, or inquiry of subscriber information is requested from the customer management system 10, the intelligent network service management system 20 receives the request to the service control system 30 which is a server. Request 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, the CSIB receives this message. Establish a session with the service control system 30 to send it to the service control system 30. Thereafter, the subscriber information management request message is transmitted to the service control system 30 through this session to request the 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 sessions, respectively, active / standby. In this case, the session refers to a separate path for transmitting and receiving messages between processes.

As such, there is a request for up to 16 sessions between the customer management system 10 and the intelligent network service management system 20. There is one process for handling requests through the multiple sessions, and one process responds to the request. You must do it. However, if a request through one session requires a lot of system resources or takes a lot of processing time, it cannot respond to other requests sent through other sessions while processing the request.

In this process, response processing is performed on a request message between a CSBS and an intelligent network service management system (SMS) of a general intelligent network service system. There is a problem in that the response processing cannot be performed, and the service processing takes a long time and a large load is placed on the process of performing the response processing.

In addition, the service processing time takes a lot of time, it was difficult to provide a quick service.

Accordingly, the present invention has been proposed to solve the above conventional problems, and an object of the present invention is to simultaneously receive a plurality of request messages from a Customer Service Billing System (CSBS), which is a client managing an intelligent network service subscriber. When transmitted to a server, the intelligent network service management system (SMS), the intelligent network service management system (SMS) distributes these multiple request messages to speed up message processing and distribute the load for message processing. An intelligent network service system of a client-server communication structure provides a method for distributing customer management needs.

In order to achieve the above object, in the intelligent network service system of the client-server communication structure according to the present invention, a customer management request distribution processing method is provided.

The customer management system in an intelligent network service management system (SMS) that manages subscriber information of a service control point (SCP) according to a request of a customer service billing system (CSBS) operating as a client Create a number of child processes for distributing the request messages. Each child process created has one-to-one correspondence with a session to manage the session between the customer management system and the service control system. Thus, when a subscriber management request message is transmitted from a client management system that is a client through a session, a child process managing the session receives and processes the subscriber management request message. In this way, one child process is managed by one child process, so that when a plurality of request messages are simultaneously transmitted from the customer management system, the subscriber management request message can be distributed quickly without any processing delay.

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

2 is a flowchart showing a customer management request distribution processing method according to the present invention.

As shown therein, a first step ST11 of generating a plurality of child processes; After performing the first step ST11, the 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, the plurality of child processes. A second step (ST12-ST14) of finding a valid session for transmitting this message to the service control system 30 among the sessions formed by the user; And performing a third step (ST15) of transmitting the subscriber information management request message through the found valid session.

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

The third step ST15 may include: checking a received signal by a child process selected in the second step ST12 to ST14; Transmitting the request message to the service control system (30) through a session if the received signal is a request message transmitted from the customer management system (10) (ST26, ST27); If the received signal check result is a response message transmitted from the service control system 30, the response message is transmitted to the customer management system 10 (ST28 and ST29).

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

First, a CSBS interface block (CSIB) of the intelligent network service management system 20 generates a plurality of child processes in a thread manner when performing initialization (ST11). In this case, the number of child processes generated is 40. The 16 sessions, which are formed between the customer management system 10 and the intelligent network service management system 20, correspond to one session and one-to-one correspondence with one session to manage the session. Sufficient number is enough. A thread is a unit of program handled by a multi-tasking function. Therefore, the conventional intelligent network service management system 20 is operated to manage a plurality of sessions in one process, but the present invention operates to create a plurality of child processes in one process and manage one session in each child process. do.

When a plurality of child processes are created, each child process initializes a network interface for interprocess communication services. Since the client-server model is applied and operated between the customer management system 10, the intelligent network service management system 20, and the service control system 30, the intelligent network service management system 20 communicates between processes in a client-server communication structure. A socket is used as a network interface for providing a service, and thus a child process initializes the socket (ST21). This socket basically provides Transmission Control Protocol / Internet Protocol (TCP / IP) and User Datagram Protocol (UDP) as the lower layer protocols. TCP / IP is a connection-oriented protocol in which interconnections are established between end-users and data is communicated over them. UDP is a connectionless oriented protocol for communicating data without end-to-end interconnection. Intelligent network service system uses TCP / IP to improve the reliability of data transmission. Therefore, the connection between the client and server process is established first before data transfer.

In order to request the subscriber information management from the customer management system 10 as a client, an attempt is made to connect to the intelligent network service management system 20 as a server. That is, the customer management system 10 attempts a TCP / IP connection request. When a child process of one of the 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. The child process then operates as a client and attempts to connect to the service control system 30 (ST23). After that, if 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 the connection point with the customer management system 10 and the connection point with the service control system 30 in the form of a table as shown in Table 1 below. Register in response.

child process 0 One 2 ... MAX_ID Access 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 represents the maximum number of processes.

Thus, one session is established 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 it needs to handle.

Then, when the customer management system 10 requests the subscriber's information inquiry 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. The message is then sent to the child process that established the session.

The child process that sent the message from the parent process checks this received signal (ST25). If the result of the check is a request message transmitted from the customer management system 10, the request message is transmitted to the service control system 30 through the established session (ST26, ST27). In this way, the intelligent network service management system 20 requests the subscriber information inquiry to the service control system 30.

While the service control system 30 is inquiring about the subscriber's information according to the request, when the request message for generating the subscriber's information is transmitted from the customer management system 10 again, the intelligent network service management system 20 performs another child process. Allows the session to form a new request message. However, in the conventional message processing method, the message processing time is delayed because the new generated message cannot be processed until the service for this inquiry message is terminated.

Then, 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 number of child processes, each child process one-to-one correspondence with the session to distribute the request message of the client management system 10 as a client, reducing the time required to process the request message and reduce the load placed on one process do.

As described above, in the intelligent network service system of the client-server communication structure according to the present invention, the customer management request distributed processing method includes a plurality of child processes in an intelligent network service management system (SMS), which is a server that processes a request message. And process the request message in a one-to-one correspondence between a session between the child process and the Customer Service Billing System (CSBS), thereby distributing each child process when multiple request messages are sent from the customer management system at the same time. This has the effect of speeding up message processing.

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 system stability.
