BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for managing a program in an electronic switchgear, and more particularly, when a specific program is changed and a program of a system is replaced by a higher version or a program replaced by a higher version during operation of an electronic switchgear system. The present invention relates to an apparatus and a method for managing the program in an electronic switchgear for providing a quick recovery when a problem is found.

First, the electronic switchgear uses a comprehensive information communication network.

Integrated Services Digital Network (ISDN):

ISDN is a digital communication network that integrates and provides various services, and ISDN is an integrated service digital communication network that enables to provide not only voice but also image and data services by developing voice communication.

At this time, the services of the integrated ambassador are mainly narrowband services such as telephone, facsimile, teletex, telemetry, telewriting, and data terminal.

Typical features of ISDN include the fact that the subscriber and the communication network are connected through one circuit so that various services can be comprehensively provided, and the connection between the subscriber and the communication network is digital.

In other words, the subscriber network is digitalized and various services are integrated thereon.

In ISDN, there is an advantage that a variety of voice and non-voice services can be integrated and processed, which is possible because all information processing is performed by digital method.

Therefore, in ISDN, circuit switching and packet switching can be provided simultaneously, and transmission is digital.

ISDN provides a common access point for existing circuit-switched and packet-switched networks, and has the advantage of allowing various information resources in the network to be shared.

In other words, it is possible to have various databases in a communication network and use them jointly with all subscribers and service providers.

In addition, ISDN can provide various communication processing and information processing functions, and has advantages such as facilitating operation and management of a communication network.

In general, a software program used in an electronic switching system is stored in a hard disk which is an auxiliary memory device through a magnetic tape (MT).

Accordingly, the program stored in the hard disk loads the relevant block into the processor at the request of the corresponding processor to perform a necessary function.

When changing a program and replacing a higher version according to the prior art, the program currently running and data called PLD (Processor Loading Data) are backed up with a magnetic tape.

The newly created program and the system magnetic tape for the higher version replacement are stored in the hard disk which is the auxiliary memory device (DUMP (meaning the contents of the magnetic tape are stored on the hard disk)).

Existing programs are then overwritten by the newly created program, so they are lost.

In this regard, FIG. 1 is a block diagram showing an embodiment of program management in an electronic switching system according to the prior art, which communicates with an operator matching processor 10 that manages operator matching and an operator matching processor 10. It includes an operation maintenance management processor 20 for managing the operation maintenance management, and a loading request processor 30 for managing the loading request to the operation maintenance management processor 20.

The prior art thus made will be described in detail as follows.

First, the operator matching processor 10 manages operator matching, the operation maintenance management processor 20 communicates with the operator matching processor 10 to manage operation maintenance, and the loading request processor 30 maintains operation. The maintenance processor 20 manages the loading request.

That is, when the program is changed and the higher version is replaced, when the input / output device control block 12 in the operator matching processor 10 receives an instruction, the device state control in the operation maintenance processor 20 receives the received instruction. Passed to block 22.

At this time, the input / output device control block 12 is a block that manages input commands and output messages during the operation of the exchange system, and the device state control block 22 is a system device such as a magnetic tape 24 and a hard disk 26. Change and control the state.

In addition, the program and the PLD data in the currently operating hard disk 26 is backed up to the magnetic tape 24 by the command transmitted as described above.

This is a preparation for recovery if a problem occurs after applying a higher version program.

After this line work is finished, the newly produced program is DUMPed to the hard disk 26 in the same manner as the line work.

At this time, the existing programs are overwritten by the newly produced program and thus disappeared.

Thereafter, when the load request blocks 32 and 34 existing in the load request processor 30 are restarted to test the function of the newly applied program, the system load control blocks 28 respectively load the load request blocks 32 and 34. To load the program.

At this time, the system loading control block 28 moves a program stored in the hard disk 26 to a memory (not shown) of the loading request processor 30 so as to control each block to perform a function. to be.

However, in the conventional technology, when a new program is applied and a functional problem is found, the magnetic tape that is backed up at the time of work is DUMPed again to the hard disk, and when a problem occurs in a higher version of the program, In order to recover, the magnetic tape backed up before the operation must be DUMPed to the hard disk, which not only wastes a lot of time, but also causes a long service interruption.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the prior art, and provides a program management apparatus and method thereof in an electronic switching system capable of smoothly recovering / managing files of an auxiliary storage device in the electronic switching system. There is a purpose.

Briefly describing the present invention for achieving the above object is as follows.

First, the system magnetic tape, which is used to change the software program used in the electronic switching system and to replace the higher version, is examined for the existence of the same file name in the DUMP on the hard disk which is an auxiliary memory device. ), Do not overwrite it, but keep it under a different file name, and save the new program to the hard disk (DUMP).

This ensures that both versions exist on the hard disk at the same time and have a disk file management function to manage the DB (Data Base) related to block loading.

If a problem is found after applying the higher version, the operator can immediately recover the existing version through the disk file management function, so that the block loading can be serviced to the corresponding processor.

When explaining the embodiment of the present invention in detail as follows.

Referring to FIG. 2, FIG. 2 is a block diagram showing an embodiment of a program management apparatus in an electronic switch according to the present invention, which includes an operator matching processor 50 and a magnetic tape 64 that manage operator matching. And a hard disk 66 and a DB 70 for loading table information, the operation maintenance management processor 60 communicating with the operator matching processor 50 to manage operation maintenance and loading request blocks. In the loading request processor 80 including the 82 and 84, which manages the loading request to the operation maintenance management processor 66, the operator matching processor 50 receives an input / output device control block 52 for receiving an instruction. The operation maintenance management processor 60 performs a DUMP on the hard disk 66 programs contained in the magnetic tape 64 in instructions transmitted from the input / output device control block 52. The newly created program is accessed by accessing the device state control block 62 and the same program on the hard disk 66 and the loading table information DB 70 when the program is dumped to the hard disk 66. To manage the files of the hard disk 66 and to manage the loading table information DB 70 for the recovery of the newly applied program by determining whether to overwrite or to preserve the existing program files. Restarting the disk file management block 68 and the loading request blocks 82 and 84 existing in the loading request processor 80 to test the function of the newly applied program accesses the DB 70 for loading table information. And a system loading control block 72 for loading the program to the respective loading request blocks 82 and 84 in the load request processor 80.

Referring to Figure 3 of the present invention made as described above is as follows.

First, the operator matching processor 50 manages operator matching, the operation maintenance management processor 60 communicates with the operator matching processor 50 to manage operation maintenance, and the loading request processor 80 maintains operation. The maintenance processor 60 manages the loading request.

That is, the input / output device control block 52 in the operator matching processor 50 receives a command and transfers the command to the device state control block 62 in the operation maintenance processor 60, thereby the device state control block 62 receives the input / output device. By the command transmitted from the control block 52, the programs contained in the magnetic tape 64 are DUMPed to the hard disk 66.

Next, the disk file management block 68 overwrites the newly created program by accessing the DB 70 for loading table information and whether the same program exists on the hard disk 66 when the program is dumped to the hard disk 66. A file of the hard disk 66 is managed by determining whether or not to save an existing program file.

In addition, it performs a function of managing the loading table information DB 70 for recovery of a newly applied program.

The system loading control block 72 then restarts the loading request blocks 82 and 84 existing in the loading request processor 80 to test the function of the newly applied program, and accesses the DB 70 for loading table information. The program is loaded into the loading request blocks 82 and 84 in the load request processor 80.

Next, when the state of the magnetic tape 64 is normal, the header portion of the magnetic tape 64 is read to extract information 102, and it is checked whether the same file name exists in the hard disk 66 as an auxiliary memory device ( 103).

If the same file name does not exist, the contents of the magnetic tape 64 are read and DUMPed to the hard disk 66 (107).

If the same file name exists, the information of the loading table information DB 60 is checked (104) to determine whether to overwrite the existing file by extracting the information of the currently running program and overwriting the existing file (105). DUMP is performed 107, otherwise, the existing file name is changed to a specific file name, stored 106, and the contents of the magnetic tape 64 are read and DUMPed to the hard disk 66 (107).

After dumping the changed program on the hard disk 66, the information of the loading table information DB 70 is changed to the latest information (200), and when the dump of the new program is completed, restart the processor to verify the new program. (201).

Next, the loading request blocks 82 and 84 read the information of the loading table information DB 70 to load the corresponding program (202), and when the loading is completed, the processor automatically starts driving (203). .

In addition, by checking the function of the new program to determine whether the function is normal (204), when a problem is found, immediately changes the information of the loading table information DB (70) to the existing version (200) and restarts the processor. In the case where there are no problems with the verification of the program, the operation of the new program is confirmed.

As described above, the present invention can simplify complicated tasks when a part of the program is changed in the electronic switching system or when a newly versioned program is applied, and the file of the hard disk 66 is automatically managed and Through the operator's command it is possible to manage the information of the loading table information DB (70).
