Description

File copying method in electronic switchboard {METHOD FOR FILE COPY IN ELECTRONIC SWITCHING SYSTEM}

The present invention relates to a file copying method in an electronic switchgear and a computer-readable recording medium recording a program for realizing the method, and more particularly, to a mother station of an electronic switchgear such as a TDX-100 (Time Division eXchange-100). In order to operate the Remote Access Switching Module (RASM) that exists separately from the system, files necessary for the operation of the exchanger stored in the mother country are transferred to the Remote Access Switching Processor (RASP) of the Remote Switching System (RASM). The present invention relates to a computer-readable recording medium having recorded thereon a method for copying and a program for realizing the method.

First, the concept of important terms used in the present invention will be described.

The Remote Switching System (RASM) is connected to the mother station of the electronic switchboard, such as the TDX-100, through a pulse code modulation (PCM) relay line, and acts as a relay for the subscribers of the mother country. It is defined as a device with a switching function by constructing a call path in a stand-alone manner in case of a connection failure.

The central control processor (CCP) is defined as the processor of the central control subsystem (CCS), which resides in the home country of the electronic switchboard and performs the overall operation and maintenance of the system.

Operation and Maintenance Processor (OMP) performs maintenance functions such as maintenance and test management in all electronic switchboards such as TDX-10A, and operation management such as network management, billing, statistics, database management, etc. Is defined as a processor.

A Man Machine Processor (MMP) is defined as a processor that enables the operator to communicate with the operator center or exchange center, such as the TDX-10A.

Man Machine Communication (MMC) is a defined protocol used between an operator and an operator that enables an operator to perform operations and maintenance tasks related to various tests, measurements, or changes of contents through an I / O device. Defined in the language.

Inter-processor communication (IPC) performs call processing by exchanging messages between a plurality of processors distributed in an exchange, and is defined as exchanging messages between processors. For this purpose, a separate IPC network exists inside the exchange.

In the conventional electronic switch such as the TDX-10A, the operation and maintenance processor (OMP), the operator matching processor (MMP), the operation and maintenance processor (OMP) and the input / output processor (IOP) The full file copy function is performed by the Disk FIle Management (DFM) block, and is supported by CROS: Concurrent Real-time Operating System (CROS), which is a high-level operating system of all electronic exchanges such as the TDX-10A. Because of the system, all files on the source disk were copied to the destination disk in priority order. In order to access the file system supported by CROS, a high-level operating system of electronic switchers such as the TDX-10A, the application only needed disk and file name information. Therefore, executable files and processor load data (PLD) required for the operation of the exchange were stored in one disk without distinction.

However, electronic exchanges such as the TDX-100 support multiple volumes (such as C or D) and directories (such as C / Prog) using an operating system such as DOS (Disk Operating System). Since the necessary executables and the processor load data (PLD) are stored in different directories according to their types, it is difficult to copy them to a copy target device such as a remote switching device (RASM) with a single command. .

In order to solve the above problems, the present invention provides a file copying method in an all-electronic switching system which copies a plurality of files necessary for the operation of an exchange with a single command input, and a computer recording a program for realizing the method. The purpose is to provide a recording medium that can be read by.

In order to achieve the above object, the present invention provides a file copying method in an electronic switch, comprising: a first step of creating a list of files to be copied in order to process file copying; And a second step of creating a new file by transmitting the name and size of the copy target file to the copy target device according to the list, receiving the contents of the copy target file, and writing the new file to the copy target device. .

The present invention also provides an electronic switch having a large capacity processor, comprising: a first function of creating a list of files to be copied in order to process file copying; And a program for transmitting a name and a size of a copy target file to a copy target device according to the list, to create a new file, and to receive a content of the copy target file and to implement a second function of recording the new file into the new file. It provides a recording medium that can be read by.

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 view of the configuration of an electron exchanger to which the present invention is applied.

As shown in the figure, the electronic switchboard includes a central control system processor (CCP) 11 existing in the mother station and a remote switch processor (RASP) 12 in the remote switching unit (RASM) existing separately from the mother station.

The central control system processor (CCP) 11 existing in the mother station of the electronic switching system includes an operating software management unit (DFM) 111, an operating system (OS) unit 112, and a storage disk 113.

The remote switching processor (RASP) 12 in the remote switching device (RASM), which is separate from the mother station, also includes an operating software management unit (DFM) 121, an operating system (OS) unit 122, and a storage disk 123.

The operating software management unit (DFM) 111, 121 recognizes the entire file copy command and processes it, and the disks 113, 123 provide a storage space for storing the files. The operating system (OS) units 112 and 122 have disks 113 and 123 having a plurality of volumes (such as C or D) and directories (such as C / PROG), and files may be stored in different directories according to their types. To be able.

2A and 2B are flowcharts illustrating an exemplary embodiment of a method for copying files between processors in an electronic switch according to the present invention.

Although the mother station of the electronic switching center and the remote switching device (RASM) are connected through the PCM relay line, the connection may be disconnected due to some reason. Therefore, when the remote exchange processor (RASP) 12 is in a stand-alone state, the operating system (OS), in order to be able to perform its own normal function by loading the files stored on its own disk 123, It is necessary to copy the necessary executables, PLDs, etc. from the central control subsystem processor (CCP) 11.

The operating software manager (DFM) 111 puts a parameter indicating whether to make a full copy in the general file copy MMC command and performs a function by recognizing a full copy according to whether the parameter is input.

The operating system (OS) of the electronic switchboard, such as the TDX-100, supports DOS (Disk Operating System), so one disk has multiple volumes (C or D), directories (C / PROG, etc.) Since they are stored in different directories according to their types, when the entire copy is performed, the files are copied from a plurality of directories and copied to a directory of the same name of the target processor.

When a copy command for the entire file is input through the MMC, the operating software manager (DFM) 111 analyzes the input data and copies the files necessary for the target remote exchange processor (RASP) 12 in order of priority. These files are stored in the C or D volume in the disk 113 of the central control processor (CCP) 11, and are stored in the C / PROG, C / PLD, and C / DATA directories according to the file type. After reading from each directory, the software manager (DFM) 111 creates and copies a file of the same name in the corresponding directory of the remote exchange processor (RASP) 12. Whenever one file is copied, the result message is printed to know whether each file is copied. Repeat this process and copy all the files necessary for loading the target remote exchange processor (RASP, 12). When copying of the entire file is completed normally, a file named 'RASP_OK' is created on the target volume to check whether the file is normally copied without checking the result message.

In addition, the continuous full copy function for multiple Remote Switch Processors (RASP) 12 can be achieved. It takes about 15 to 20 minutes, and it is possible to receive multiple inputs of the target remote switching processor (RASP, 12) among the command parameters at the same time as 'RASP = 0 & 1 & 2 & 3'. It is possible to make a full copy to RASP (12). If there is an input of such a command, the operating software management unit (DFM) 111 performs the entire file copy operation from the central subsystem processor (CCP, 11) to the remote exchange processor (RASP, 12), and then back to the target remote exchange processor (RASP). , 12) to perform the function by copying to the next remote exchange processor (RASP, 12).

Since file copying between processors uses interprocessor communication (IPC), file copying to multiple remote switching device processors (RASP, 12) at the same time can dramatically increase the IPC load of the system. If multiple information on the target remote exchange processor (RASP, 12) is entered, perform the entire file copy function to one remote exchange processor (RASP, 12), and then go to the next remote exchange processor (RASP, 12) information of the input parameters. Change the target remote exchange processor (RASP) 12 and repeat the entire copying process for the files required for loading the remote exchange processor (RASP) 12 again.

Repeat the entire copy function in sequence, so use the same output message as the full copy function for one remote exchange processor (RASP, 12), but continue with 'CONTINUE' if the target remote exchange processor (RASP, 12) remains. Indicates that it is in progress.

This will be described in sequence as shown in the flow diagram as follows.

Process 1 for processing a full file copy is made by inputting a full file copy command required for the exchange operation (201). It is checked whether the input parameter is an executable request (202). If it is confirmed that the input parameter is not executable, the cause and result are displayed (204), and the process ends.

As a result of checking whether the input parameter is feasible, if it is feasible, it is determined whether the state of the processor or the disk on which the copy function is to be performed is normal (203). As a result of the determination, if the processor or disk state is not normal, the cause and effect are displayed (204), and the process ends. As a result of the determination, if the processor or the disk state is normal, the list of files to be copied to the copy target RASP is prioritized (205).

The file types can be broadly classified into MMS data, PLD, and a.out. MMS data necessary for environment configuration targets all files in the / C / DATA directory. In the case of processor load data (PLD), Only one for the corresponding RASP in the / C / PLD / P_R directory. The executable file a.out searches for the R_BLK_ list relation among the files in all subdirectories of / C / PROG, Only buffer the necessary files in the list. At this time, the OS, shell, and PL_CM files required for system execution are prioritized to be copied first.

A signal is sent to the target RASP for file copy, requesting the creation of process 2 to perform the file copy at the RASP (206). RASP creates Process 2 to ensure that a full file copy is made (207).

Process 1 checks whether the target file exists in the CCP according to the order of the copy target file list created (208). As a result of the check, if the target file does not exist in the CCP, the cause and effect are displayed (217), and it is determined whether or not it was for the last file of the copy target file list (219).

As a result of checking whether the target file exists in the CCP, if it exists, the file is opened to store the file size (209), and the name and file size of the copy target file are transmitted (210) to the process 2 of the RASP.

Process 2 deletes the existing target file according to the received copy target file name and file size, creates a new file with the same name, and secures space equal to the file size (211).

In RASP, process 2 checks 212 whether the file creation was successful. As a result of the check, if the file is not generated correctly, the cause and the result are displayed (217) and the process 1 of the CCP is informed to determine whether the file is the last file of the copy target file list (219).

When process 2 checks whether the file is created correctly, it notifies process 1 that it is ready to copy (213).

Process 1 reads the contents of the target file and transfers it to the copy target RASP (214), and process 2 of the copy target RASP writes the transferred file contents to the newly created file (215) and checks whether the copy of the file has been made correctly. Check (216). As a result of the check, if the file is not copied correctly, the cause and effect are displayed (217), and it is determined whether the file is the last file of the copy target file list (219).

As a result of checking whether the file is copied correctly, if the file is copied correctly, the result is displayed (218), and it is determined whether the file is for the last file in the copy target file list (219).

As a result of determining whether the file is the last file of the copy target file list, repeating the process of checking whether the target file exists in the CCP by changing the copy target to the next file in the copy target file list (220). Do it.

As a result of determining whether the file is the last file of the copy target file list, if it is the last file, it indicates that the entire file copy has been performed (221), and checks whether there is more target remote exchange processor (RASP) to copy (222). As a result of the check, if there are more RSPs to be copied, it indicates that the copy is in progress (223), changes the RTP to be copied (224), and then signals to the target RASP of the whole file copy. The process is repeatedly performed from step 206 of requesting generation of process 2 to copy a file in the RASP.

As a result of checking whether there is more target RAP to copy, if not, it indicates that the copy is completed (225) and terminates.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

In the present invention as described above, in preparation for a stand-alone state such as a remote exchange processor (RASP), the operator's file by processing the file copy required for the operation of the exchange with a single command input to a plurality of files There is an effect that can provide administrative convenience.

In addition, the present invention can increase the convenience of the operator by allowing a plurality of files to be copied to a plurality of copy targets with a single command when a file copy request is requested for a copy target such as a plurality of remote exchange processors (RASP). In addition, the sequential file copy function has the effect of reducing the load on the system.
