Description

Method for form filling command processing in switching system}

In the present invention, in the exchange system that executes distributed processing in the exchange controller and executes a data processing function with low real-time characteristics in the system manager, the format input command is inevitably followed when improving or adding a function of the system. The present invention relates to a method of processing a form input command 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.

Input / output instructions are basic in operator matching for the operation and management of the exchange system consisting of distributed systems.

However, a form filling method may be used for an input error of an input / output command and an inexperienced operator.

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 that exchanges a result with a corresponding command is required between an input / output command and a switch function. At this time, the format input form was formed based on the definition file for the command.

Therefore, conventionally, when a new function is added, it is necessary to implement an exchange function for defining a message and a signal and performing a function in an I / O command definition, and at this time, the types of commands to be performed by the exchange and for each command. After the verification data was completely rewritten, the operator matching function was rerun to provide format input.

As such, conventionally, all I / O command processing refers to a predefined I / O format file and relies on message communication, thus losing the flexibility to package information on the definition of I / O commands as a whole and to write exchange management software dependent on such data. It was an operator method.

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

However, in the related art, the instruction software is not dependent on the function provided by the exchange, but the exchange software is developed based on the overall input / output instruction system. That is, the information on the input / output instruction part was first constructed on the entire software package, and the information was compiled and packaged with the function dependent on the constructed information.

This conventional method has a problem in that when the exchange needs to add a new function during operation, it causes the entire packaging process to undermine the flexibility of the system and restart the operator matching part. 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 problems as described above, when adding a format input command in a distributed architecture exchange system, using a web server to form a message between the command input and output functions and the exchange function without the process of defining the input and output commands The purpose of the present invention is to provide a method of processing a form input command to improve the function of the exchange software by providing new inputs without interrupting the function of the exchange, and to provide a computer-readable recording medium recording a program for realizing the same. have.

Gain performance flexibility.

In addition, in constructing an instruction processing program, each of the independent instruction processing programs inputs the command information to the instruction link file when the input arguments which are commonly executed for the form input processing are forms, and the input arguments If not present, the format of the command input argument is passed to the client's format input window and the command is processed when the command is entered.

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 other switching unit 13 and the link 131 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 a remote program execution and a remote file access method.

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 through the web server 226 via the management interface 225, which is a common gateway, and 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 message communication between the processor of the switch controller 11 and the process 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 a diagram illustrating an embodiment of a method of processing a format input command according to the present invention.

The present invention is an input / output instruction that is inevitably followed when improving or adding a function in a distributed real-time exchange system to process a format input instruction by using an exchange input / output method using a web server 32 and a web browser 31. I / O commands added at the time of addition can be added flexibly without disturbing the system.

As shown in FIG. 3, in order to process the format input command in the system manager 12, the operator first selects the format input on the command processing client window provided on the web client 31. Here, the item for the format input is provided when setting the frame of the initial window.

Thereafter, the operator's selection of the format input is transmitted to the web server 32 which is a command server (301), and the web server 32 executes the command link information transmission unit 33 as a child process (302). At this time, the command link information transmitting unit 33 performs the switch command programs 35 in the system manager 12 one by one (303), while each switch command program 35 performs basic information of the format input. The information about the command to be included in the file is transmitted to the command link information transmission unit 33 (304).

Next, the command link information transmitting unit 33 transmits the contents of the file to the web client 31 through the web server 32 after the execution of all the exchange command programs 35 is completed (305, 306). At this time, the web client 31 opens a format input window to list the format input commands.

If the operator selects one of the outputted input commands, the selected result is transmitted to the web server 32 which is the command server through the web client 31 (307), and the web server 32 transmits the corresponding system manager ( 12, the exchange instruction program 35 is executed (308). At this time, when the switch command program 35 in the system manager 12 transmits the argument input format of the command to the web client 31 through the web server 32 (309, 310), the input argument on the web client 31 is received. The format that can be inputted is displayed in the format input window.

On the other hand, the operator can input the argument in the output form input form to request processing, which is transmitted to the web server 32 by the command name and the argument via the web client 31 (311), the web server 32 In operation 312, the command analyzer 34 executes the child process for processing.

Subsequently, the command analyzer 34 decodes the input command and executes the switch command program 35 of the system manager 12 in a child process (313). The switch command program in the system manager 12 at this time is most of the functions in the system manager 12 of FIG.

If the exchange command program 35 of the system manager 12 needs more detailed information in the exchange system 36, it can query the exchange system 36 by message (314). Thereafter, the exchange system 36 transmits the result according to the request to the exchange command program 35 in the system manager 12 (315), and the exchange command program 36 in the system manager 12 outputs the result for the command. Is transmitted to the web client 31 via the web server 32 (316,317).

In the past, all of these functions depended on message communication such as signals, so all the functions remained in memory and occupied the memory resources unnecessarily by waiting for a message. The only program that should be running is the web server 32, which is a command server.

4 is a detailed flowchart illustrating a method of transmitting command link information in a format input command processing method according to the present invention.

In the present embodiment, a method of transmitting information about a format input to a client operated by an operator is performed by a child process while passing an input argument to all the command processing programs to construct a link information file to transmit information on the command to the client. By transmitting, it is possible to construct a flexible exchange system that ensures function scalability and flexibility.

As shown in FIG. 4, in the form input command processing method according to the present invention, the command link information transmission process in the command link information transmission unit 33, which is a child process of the web server 32, which is a gateway of the command server, is performed first. In order to execute all of the switch command programs 35 in the system manager 12 as a child process, a value of "form" representing a form input is given to the input argument (401). Thereafter, the above steps 401 are repeated for all the exchange command programs 35 until the execution of all the exchange command programs 35 is completed (402, 403). In this case, each exchange command program 35 receives an argument of "form" in the case of form input, and writes information about itself to a file.

Thereafter, the command link information file thus prepared is read (404) and the read command link information is transmitted to the web client 31 through the web server 32 (405).

5 is a detailed flowchart illustrating an example command analysis process in the method for processing a format input command 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.

FIG. 6 is a detailed flowchart illustrating a format input command allowing process in a method of processing a format input command according to the present invention, in which exchange command programs 35 in the system manager 12 commonly allow format input. Represents a procedure for processing.

In this embodiment, in processing the switch command program 35 in the system manager 12, when each independent switch command program 35 has a common execution for the form input processing, an input argument to be input is formed. In the case of inputting command information in the command link file, and if there is no input argument, the format of the command input argument is transmitted to the format input window of the web client 31, and the command processes the command upon input.

As shown in FIG. 6, the format input instruction allowance process of the format input instruction processing method according to the present invention may be a first input argument input when the exchange instruction programs 35 in the system switch 12 are executed. form 301 is analyzed.

As a result of the analysis, when "form" is input as the first input argument, this means to include information about the command in the command link file, and thus, stores the command type, the description of the command, and the command name (602).

As a result, if "form" is not input as the first input argument to be input, it is checked whether the first input argument is null (603).

If the result of the check is that there is no first input argument (that is, "null"), the command argument format is transmitted. Therefore, the format of the input argument of the command that is processed is transmitted to the web client 31 through the web server 32. (604).

If more than one input argument is entered as a result of the check, it means that the instruction is processed. Therefore, the validity of the input argument is examined (605), and then the instruction processing according to the characteristics of the instruction is performed (606). In operation 607, the instruction processing result is transmitted to the output window frame.

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.

As described above, the present invention can flexibly expand instruction matching without changing the entire operation of an existing exchange when a new function is added among operator matching functions of an exchange system, especially when processing a format input instruction, In order to reduce the software required to reside in the memory, the memory can be used efficiently, thereby increasing the flexibility of the system.
