Description

How to back up the operating program and database of the exchange system

The present invention relates to a method of backing up an operating program and a database file in an exchange system, and more particularly to a method of backing up a file only of a changed portion of the operating program and a database file.

Typically, the exchange system has an operating program and a database (DB), which is called a package, and configured to perform call processing services of subscribers registered in the exchange system. do. In addition, the operation of the exchange system is made by a file for the package, and the package is stored in an auxiliary storage device such as a hard disk drive inside the exchange system. Storing such a package in a predetermined computer connected to the outside of the exchange system is referred to as a PC backup. In addition, the computer is responsible for the maintenance function of the exchange system, and thus stores the package of the system. Such computers are commonly referred to as Maintenance and Administration Personal Computers (MAPs).

The PC backup operation as described above is important when copying a package stored in an arbitrary exchange system for use in another system, or storing the upgraded package in a MAP so that the upgraded package can be operated in the system when the package is upgraded. to be.

On the other hand, in the PC backup method as described above, conventionally, since the computer receiving the backup has to store all the files for the existing package, there was a hassle to back up all the upgraded packages every time the package is upgraded. At the same time, there was a problem that it takes a long time to perform a PC backup.

Accordingly, the present invention provides a method for PC backup of a package in an exchange system, which minimizes the time loss caused by PC backup of all packages, and promotes user convenience. To provide.

In order to achieve this object, the present invention proposes a method of backing up only the upgraded parts of existing package files in an exchange system.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating hardware of an exchange system for carrying out the present invention.

Referring to Fig. 1, an exchange system is connected to a switch 100 and a maintenance computer 130 (MAP; Maintenace and Administration Personal Computer), which is an externally connected computer that performs a maintenance function of the switch 100 through a predetermined communication protocol. . In addition, the input / output unit 110 (IPM; Input / output Processor Module) processes the overall input / output operations of the switch 100, and transmits and receives data with the MAP 130, the package that is the operating program and the DB file of the switch 100 from the MAP 130 auxiliary memory To be stored on device 115. In general, the auxiliary memory device 115 is implemented as a hard disk drive (HDD), and stores the package of the exchanger 100. The data transmission / reception bus 120 is a data bus connecting the MAP130 and the switch 100 and has an HDLC / LAPB protocol bus structure.

2 is a flowchart illustrating a backup method of an operating program and a database according to the present invention, and FIG. 3 is a procedure diagram illustrating the operation process of FIG. 2 in chronological order. The reference portion shown in FIG. 3 is displayed corresponding to each step of FIG. 2.

2 and 3, in step 201, the MAP130 transmits a request for PC backup to the switch 100. In step 202, in response to the request received in step 201, the switch 100 transmits a response to the PC backup progress and version information of the existing package stored in the auxiliary storage device 115 of the switch 100 to the MAP130. Here, the version information refers to a package for PC backup, that is, information on the production date of the main or firmware (F / W) and the version number of the package. The user who has received this information can know the changes of the package with reference to the information, and thus can select a package to be backed up. In step 203, the MAP130 starts PC backup and transmits a request for a directory list to the switch 100. In this case, the directory list represents information on packages of the exchange system. In other words, information representing the file between the switch 100 and the MAP 130 is used to determine a file to be backed up.

The structure of the directory list is shown in FIG. 4 attached. Referring to FIG. 4, FILE NAME401 represents the name of the file and is represented by ASCII characters of 12 bytes. LOADING ADDRESS402 indicates the address of an address loaded into the main memory of the exchange 100. DATE TIME403 represents the year / month / day / time / minute when the file was created as a binary value. ATT404 represents the attributes of the Syseg file, and CST_NO.405 represents the starting cluster number. FILE SIZE (ORG) 406 represents the size of the original uncompressed file in bytes, and status FILE SIZE 407 represents the size of data stored in the auxiliary memory device 115 in bytes. In the present invention, the PC backup operation is performed by using such a directory list. When the first backup is performed, all packages are backed up because there is no directory list. If a list is requested, the directory list for the package received by the switch 100 is compared with the directory list of the MAP130 to back up the package for the changed directory list.

If a directory list having the above structure is requested in step 203, the switch 100 transmits data corresponding to the directory list to the MAP130 in step 204. In step 205, the MAP130 transmits the PC backup data request to the switch 100, and in step 206, the switch 100 transmits the PC backup data to the MAP130. In step 207, the MAP130 and the exchange 100 transmit a PC backup end request to each other to terminate the PC backup operation.

However, if the response to the PC backup progress and the version information transmission is not performed in step 203, the step 207 is performed, in this case, if the date and version information of the package of the switch 100 is the same as the previous backup to be. In addition, steps 203 and 204 are repeated for all selected directory lists. Steps 205 and 206 are repeated for all files corresponding to the directory list.

As described above, the present invention has the advantage of reducing the backup time since only the files for the changed package are processed when the package of the exchanger system is backed up at the MAP.

In addition, the present invention has an advantage of increasing the convenience of the user because it automatically detects and backs up the changed files during the backup of the package.
