Description

Method for text command processing in switching system

In the present invention, in an exchange system in which a real-time function is distributed in an exchange controller and a data processing function having a low real-time characteristic is processed in a system manager, when an input / output command is inevitably followed when improving or adding a function of a system, The present invention relates to a text input / output command processing method that can be added flexibly without interrupting the system, and to a computer-readable recording medium having recorded thereon a program for realizing the method.

In general, text input / output commands are used for the operation and management of an exchange system consisting of a distributed system.

In the conventional exchange system, the input / output command receives the command input / output function, interprets the command, and then transfers the command to the switch function using the message transfer. The switch function performs the operation according to the command and then outputs the result as a message. Delivered to function.

However, in order to perform a series of processes using this, a definition file for a command for interpreting a command is required, and a definition of a signal for transmitting and receiving a command with a corresponding command is required between an input / output command and a switch function.

Therefore, when a new function is added, it is necessary to implement the exchange function to define the message and signal and to perform the function when defining the input / output command. In this case, the type of command to be performed by the exchange and verification of each command The data has been completely rewritten.

Text input commands and result outputs for the operation and management of the exchange are closely related to the functions of the exchange.

However, in the related art, all input / output command processing is dependent on message communication, and since the information on the definition of the input / output command is packaged and maintained as a whole, the operator matching method which loses flexibility is used.

As described above, the command is not dependent on the functions provided by the exchange, but the exchange software is developed based on the overall input / output command system. In other words, the information about the input / output instruction part is first constructed on the entire software package, and the information is compiled and packaged depending on the function.

However, this conventional method has a problem of causing the entire packaging process when the exchange needs to add a new function during operation, thereby impairing the flexibility of the system. In addition, since all processes in the input / output process rely on message communication, there is a problem in that unnecessary software resources are wasted because all the software waits for message delivery while the software resides in memory.

The present invention proposed to solve the above problems is, when a new exchange function is added in a distributed architecture exchange system, the input and output definition and added to the added part without repackaging process for the existing software package is added By applying software functions directly, it is possible to flexibly improve the function of the system and to reduce the software that needs to reside in memory for input / output of instructions by allowing the programs in the input / output process to be executed by the instruction server's own program on demand instead of residing in the memory. It is an object of the present invention to provide a text input / output command processing method for efficiently using a memory and a computer-readable recording medium having recorded thereon a program for realizing the method.

And a second step of notifying the client.

In addition, the present invention provides a program in a text input / output process in an exchange system including a processor that executes a real-time function for a text input / output instruction for operation, and a system manager performs a distributed processing of a data processing function having a low real-time characteristic. Do not reside in memory but perform on-demand by the command server's own program, and if the client's activation status is reported to the command server, the command server runs a first-party process to suit the user's suitability, window settings, and frames. Control of a setting, a first function of checking an activation state of said client and reporting it to said client; And when a command is input from an operator through the client, analyzes the command input from the command server, executes a second party process, and executes a command program for the command in the second party process to read the command processing result. A computer readable recording medium having recorded thereon a program for realizing a second function of informing a client is provided.

The present invention secures a text input / output process using a commercially available web server and a web browser to flexibly add input / output commands and functions in a distributed real-time exchange system.

To this end, the present invention uses a web server for the management of the exchange system and executes a program for managing the exchange as a child process of the web server CGI.

Therefore, the present invention can secure the flexibility of the expansion of the switch and the development of a new service by proposing an operation system using the web by executing the program managing the exchange system as a CGI child process.

In the present invention, a client / server structure composed of a web server and a web browser widely used in the Internet environment is used, and when a web client is connected to an instruction structure primarily for an execution structure, control of user suitability, window setting, and frame setting is performed. A first party program that checks the client activation state is commonly performed for all clients, and as a next step, a different second party program for processing each individual command is entered. Therefore, only the second party program needs to be added to add a command due to the addition of a new function while the system is in operation.

In view of the characteristics of the present invention, in an exchange system that executes distributed processing in the exchange controller and processes data processing functions having low real-time characteristics in the system manager, the purpose of operator registration in consideration of scalability for independent development of the exchange software is provided. When configuring the correlation of functions for processing text commands, the relationship between the functions for text input and output in the system manager is related to the child process of the web server so that no message communication is performed so that the related programs do not reside in memory. .

In addition, the client's activity is checked in a predetermined unit (preferably 5 seconds) to manage the actual existence of the client, and after the client is created, the client address, the window name, and the user information are managed as the activation time. Preferably 5 seconds) to check the activation state of the client, and if the information reported from the client is the client extinction, the management client is deleted and reflected in the real-time system information output.

In addition, when a client is requested by the web browser, the user information is requested. When the user information is received, the window is divided into a command input frame, an output frame, a real time information output frame, and a client active report frame. Configure the client.

Also, it analyzes the command input from the client and separates the command name and arguments, finds an exchange management program that has the same name as the command, and if it exists, runs the program as a child process to pass the arguments so that the command can be processed. If not, notify the command error.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of an exchange system to which the present invention is applied.

As shown in FIG. 1, an exchange system to which the present invention is applied includes a switching unit 113 that executes data exchange, a matching unit 111 and 112 connected to the switching unit 113, and a processor 114 that controls the exchange. An exchange controller 11 composed of one or more subsystems coupled together, and a system manager 12 composed of a monitor 122, a computer body 121, and a storage device 123, which is in charge of information processing and system management. It is provided.

The matching units 111 and 112 of the switching controller 11 are connected to the external subscriber station 14 and the link 132 in the case of the subscriber matching device, and the link 131 and the other exchange 13 in the case of the relay line matching device. Leads to.

The matching section 111 and the switching section 113 in the exchange controller 11 are connected by an internal data transmission link 118.

In the processor 114 of the subsystem of the exchange controller 11, software 115 for controlling data exchange and software 116 for controlling the control are mounted for the control of the matching unit 111 and the switching unit 113. .

In the case of multiple subsystems, the exchange can go through three stages of data exchange. At this point, there is a subsystem with a central switching section 117.

The system manager 12 is equipped with software 124 for managing the service state and resource state of the entire exchange controller 11 or managing information necessary for exchange, and is responsible for information processing and operator registration. In addition, the storage device 123 stores information on billing and service statistics.

2 is a diagram illustrating an embodiment of a software structure for configuring a flexible switching system to which the present invention is applied.

The present invention is to design and apply an interface for information exchange between the exchange system in the structure to clarify the distribution between the functions for the real-time portion and the data processing portion for the convenience of the application program, such an interface constitutes the exchange and It is possible to implement the exchange function with the least influence on the difference of the existing hardware or the operating system to secure the development and reuse of the application function and to provide a unified exchange software platform.

In order to provide such a unified exchange software platform, the software 115, 116, 124 is located separately in the system manager 12 and the exchange controller 11.

The program of the exchange controller 11 resides in the memory and operates, and the software 124 of the system controller 12 operates only in the memory for the application program, and the application software resides on the disk and is required for the interface function. Run at hour.

The real time operating system 201 is operated in the processor 114 of the exchange controller 11, and the general purpose operating system 211 is operated in the system manager 12.

The processor 114 of the exchange controller 11 and the system manager 12 exchange information by a communication protocol.

The application program interface 210 is provided in the exchange controller 11 so that modification of the application software does not occur depending on the type of protocol that the real time operating system 201 of the exchange controller 11 can accommodate.

Software 124 of system manager 12 utilizes a remote library, remote shared memory, and remote process to communicate with software 115 and 116 of exchange controller 11. An application program interface 210 for this purpose is located in the exchange controller 11. In addition, the system manager 12 also operates an application program interface 212 for communication required by the exchange controller 11. At this time, the interface for accessing the system manager 12 from the exchange controller 11 is remote program execution and remote file access.

The processor 114 of the exchange controller 11 performs real time tasks such as signal processing, call control, number translation, route control, and the like (203).

The call service statistics collection unit 202 is notified of the progress of the real-time operation, and the statistical information notified to the call service statistics collection unit 202 is provided to the system manager 12 through the application program interface 210 provided in advance. It is delivered to the billing / statistics unit 219 via the application program interface 212 of the and is stored in the operation / management information database 218. The various information and data to be referred to in this real time task utilize the control data 204 in the shared area on the memory.

The control data 204 is changed by being changed and maintained through the system manager 12 and by the events occurring in the exchange controller 11. Here, the event in the switch controller 11 is a substantial service and failure state change.

The change of the fault state is changed by the state monitoring unit 205 and the testing unit 206. In addition, the change of the failure is transmitted to the failure analysis and alarm output unit 217 of the system manager 12 through the application interface unit 210, 212, the contents are delivered to the operation / management information database 218 and at the same time It is output to the web browser 228 of the operation manager via the web server 226 via the management interface 225 which is a common gateway, and is transmitted to the integrated network manager 229 through the integrated network management application interface 227. do.

When the system manager 12 changes the control data 204 of the switching controller 11, it is changed by a request from an operation manager or a network management center.

The request of the operation manager is via the operation interface 225, which is a common gateway implemented using the web server 226 and the web browser 228. The operation interface analyzes the input command to operate the programs 213 to 216 in the corresponding system manager 12.

For example, when an operator request for signal point registration, number registration, route registration, and service registration 213 is input, the corresponding program 213 is operated via the management interface 225 to operate the operation / management information database. After changing 218, the control data 204 is changed through the service control unit 207 of the exchange controller 11 via the application program interface unit 212, 210, and based on the changed control data 204 in real time. The function is activated.

On the other hand, when a request relating to startup management is input, the startup management unit 214 interacts with the startup control unit 209 of the exchange controller 11 to load the necessary function into the exchange controller 11.

When the change in the exchange configuration is input, the shape change unit 215 is operated to change the shape related matters in the control data 204 via the shape control unit 208 of the exchange controller 11.

When a control command for whether the test or monitoring is in progress is input, the system control unit 216 is operated to change the control data 204 via the state monitoring unit 205 or the test unit 206 in the exchange controller 11. do.

In this manner, the contents changed by the operator command in the system manager 12 are reflected in the operation / management information database 218 and the control data 204 of the system manager 12, and an event occurring in the exchange controller 11 is also included. It is stored in the control data 204 and the operation / management information database 218 of the system manager 12.

Thus, commands related to the output of various information or the status of services and resources may be performed by the system manager 12 itself. As a function of the system manager 12, the call control information output unit 220, the resource status output unit 221, the charging statistics information output unit 222, the shape output unit 223, and the system control information output unit 224. There is).

As described above, the structure of the software for the flexible switching system configuration to which the present invention is applied is the software in the system manager 12 without using message communication between the software in the processor 114 of the switching controller 11. Do not use message communication between them. In addition, since the application software does not directly use the message communication between the processor of the switch controller 11 and the processor of the system manager 12, and uses the application program interface units 210 and 212, the software is converted into system-independent software. Can increase the reusability of the exchange system software.

As such, the software structure for the flexible exchange system configuration to which the present invention is applied is classified into various types of software loaded and executed in the exchange system as having real-time characteristics and information processing characteristics. It has the advantage of improving the exchange performance by using a general-purpose computer, and communicates the interface between the exchange controller responsible for real-time control and the system manager, which is a general-purpose computer responsible for information processing. Use application program interfaces to avoid protocol restrictions.

Therefore, the software structure for flexible switching system configuration can always be used independently of the configuration of the switching controller 11. In addition, the software in the real-time exchange controller 11 also has a simple software configuration, thereby improving reusability, and when using a general-purpose computer, the information processing related program does not need to reside in memory because of its weak real-time characteristics.

Therefore, the software structure for flexible switching system configuration uses a common gateway technique using the web server 226 to execute a program that does not reside in memory by an operation / management command. In addition, an integrated network management application program interface is designed and provided to use a management program written in a modular form within a general-purpose computer without any change.

3 is an explanatory diagram of a text input / output command processing method according to the present invention, and shows a processing procedure of a text input / output command in the system manager 12.

The present invention can evolve the function of the exchange software by adding a new command without interrupting the function of the message definition and I / O command between the command input / output function and the exchange function using the web server, and without interrupting the function of the exchange. Operator instruction processing, operator matching that can be added flexibly without adding to I / O instruction added when adding or adding I / O instruction that is inevitably followed when enhancing or adding function in distributed real-time exchange system. Interfacing technology.

Accordingly, the present invention secures the text input / output processing process using a commercially available web server and a web browser to flexibly add input / output commands and functions in a distributed real-time exchange system, thereby distinguishing the real-time and non-real-time characteristics of the exchange system. It handles text I / O commands for operation in an exchange system consisting of a manager and a distributed switch controller.

As shown in FIG. 3, in order for a text input / output command to be processed, an operator first accesses a web server 32 which is a server for command processing on the web client 31, and the web client 31 is periodically configured. It reports that the web client 31 is active and also reports when the web client 31 terminates (301).

Thereafter, the web server 32 operates the window setting and management unit 33 as a child process by accessing the web client 31 which is a web browser (302).

Next, the window setting and management unit 33 is composed of a plurality of independent programs to control the user's suitability, the window setting and the frame setting on the web client 31, and check the activation of the web client 31. do. In addition, the window setting and managing unit 33 refers to the address and window name of the web client 31 for outputting the real time message to the real time message processing unit 35 through the file (303). The result of the window setting at this time is notified to the web client 31 via the web server 32 (304, 305).

If information to be reported in real time in the exchange system 37 is generated and transmitted to the real time message processing unit 35 (306), the real time message processing unit 35 displays the result of the window setting and management unit 33 as a result. The information may be transmitted to the real time processing frame of the web client 31 through the web server 32 (307 and 305).

On the other hand, when the operator inputs a command in the generated web client 31 (308), the command is a command process of the command analyzer 34 for analyzing the command in the web server 32 via the web server 32 as a child process. To generate and process (308, 309).

Thereafter, the command analyzing unit 34 decodes the input command and executes the switch command processing program 36 of the system manager 12 in a child process (310). At this time, the switch command program 36 of the system manager 12 is most of the functions of the system manager 12 of FIG.

Next, when more detailed information in the exchange system 37 is required, the system manager exchange command program 36 can query the exchange system 37 by information (311). At this time, the exchange system 37 transmits the result according to the request to the system manager switch command program 36 (312), and the system manager switch command program 36 sends the result of the command through the web server 32. Forward to client 31 (313,314).

In the related art, since the command processing function as described above is dependent on message communication such as a signal, all functions remain in the memory and wait for a message, thus unnecessarily occupying memory resources, but in the present invention, the web server 32 is used. The only programs that should always be running on the memory are the web server 32 and the real-time message processor 35.

As described above, the present invention relates to the relationship between the functions for the text input and output in the system manager 12 in the association configuration of the function for processing the text instruction, for operator registration considering the scalability for independent development of the exchange software. The function can be extended by operating in a relationship of the child process of the web server 32 so as not to communicate with the message, so that the related program does not reside in the memory.

4 is a detailed flowchart illustrating a window setting and managing process in a text input / output command processing method according to the present invention.

This embodiment checks the activity of the web client 31 every five seconds to manage the substantial presence of the web client 31, and after creating the web client 31, the address and window name of the web client 31, The user information is managed by the activation time, and the web client 31 is checked when the information reported from the web client 31 is destroyed of the web client 31 by checking the activation state of the web client 31 every 5 seconds. It is deleted and reflected in the real-time system information output.

When the web client 31 is requested to generate the web client 31 by the web browser 31, the present embodiment requests user information. When receiving the user information, the user inputs a command input frame, an output frame, and a real-time information output after examining the validity of the user. A window is divided into a frame, and a client active report frame, to configure and manage a window configuring a client.

As shown in FIG. 4, the window setting and managing unit 33 configures functions with four independent programs. These include functions 401 to 405 for monitoring the activity of the web client 31, functions 406 to 407 for requesting user information and a password when the web client 31 requests a connection, and determining user suitability. And a function 408 to 411 for transmitting the frame structure for input / output to the web client 31, and for changing the activation time upon receiving the report that the web client 31 is activated or managing the destruction of the web client 31. Each of the functions 413 to 416 is configured independently.

The function of monitoring the activity of the web client 31 is to prevent the false web client 31 from being present due to a notification error about the extinction of the web client 31. The function is generated when the system manager 12 is started. It works infinitely.

In detail, first, a search is performed in a period of 5 seconds (that is, stopped for 5 seconds) (401) and a time for reporting whether the web client 31 reports that it is activated (402). Thereafter, it is analyzed whether the current time minus the time of reporting the activity to the web client 31 has elapsed 5 seconds (403).

As a result of analysis, if the value obtained by subtracting the time of reporting activity to the web client 31 from the current time has elapsed for 5 seconds, after deleting the web client 31 (404), it is determined whether the next web client 31 exists. Inspect (405).

As a result of the analysis, if the current time minus the time of reporting the activity to the web client 31 is less than 5 seconds, it is checked whether the next web client 31 exists (405).

As a result of the check, if the next web client 31 exists, the search time 402 of the next web client 31 is reported to the web client 31 if it is activated. In other words, the server reports the time when it reported that it is activated to the web client 31 (402). That is, when the checking of the active time of all the web clients 31 ends, the execution is stopped for 5 seconds again.

On the other hand, a function of requesting user information and a password when the web client 31 requests a connection is generated and executed by the child process of the web server 32 when the web client 31 first accesses the server. All that is asked is user information and password. When it is notified that the web client 31 has been created (406), it outputs a screen requesting user information to the web client 31 (407).

In addition, the function of determining the user suitability and transmitting the frame structure for input / output to the web client 31 includes the information inputted by the user information from the web client 31 being transferred to the web server 32, and the web server 32. What is performed by the child process is a function of transmitting the user information retrieval and the configuration of the input / output frame to the web client 31.

Looking specifically at such a function, if the user information is received (408), it is searched to analyze whether it is an allowed user (409).

As a result of the analysis, if the user is not allowed, a disallowed message is output (412).

As a result of the analysis, if the correct user is allowed, the web client 31 is requested to generate a command input frame, a command result output frame, a real-time information output frame, and a web client active report frame (410). Here, the client activity report frame reports its address and window related information through the web server 32 in units of 5 seconds. Thereafter, the address, the window name, the user information, and the active time of the web client 31 are stored for use in the management of the web client 31 (411).

Finally, the function of changing the active time by receiving the report that the web client 31 is activated or managing the destruction of the web client 31 is activated (413) when receiving the report that the web client 31 is activated (413). Check (414).

As a result of the inspection, if the web client 31 is in the activated state, the activation time of the web client 31 is changed (415). If the web client 31 is not in the activated state, the web client 31 is deleted (416).

5 is a detailed flowchart illustrating an example command analysis process of the text input / output command processing method according to the present invention.

The present embodiment analyzes the command input from the web client 31 to separate the command name and arguments, finds an exchange management program having the same name as the command, and if so, runs the program as a child process to execute the arguments. It can extend the text input / output command processing function by letting it process the command and notifying the command error if it does not exist.

As shown in FIG. 5, the command analysis process of the text input / output command processing method in the command analysis unit 34 is performed when the command is first input from the web client 31 to the web server 32 (501). In section 34, the web server 32 performs the child process.

Thereafter, the command analyzer 34 separates the command name from the argument (502) and searches whether a program having the same name as the input command exists (503).

As a result of the search, if a program having the same name as the input command exists in the system manager 12, the input argument is passed to the child process while operating the program as the child process (504), and the program having the same name as the command is sent to the system manager. If not present at (12), a command input error is notified (505).

Various subsidiary processes, including actual command argument errors, allow various exchange management programs in the system controller 12 to proceed and deliver the results to the web client 31 via the web server 32.

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

The present invention as described above, when adding the text input and output instructions in the operator matching function of the exchange, it is possible to flexibly expand the instruction matching without the overall change of the existing operating exchange, and to reside in the memory for the input and output of instructions Reduced software has the effect of making efficient use of memory.
