METHOD FOR STORING AND RESTORING DATA OF A
TELECOMMUNICATIONS INSTALLATION AND CORRESPONDING
TELECOMMUNICATIONS INSTALLATION
The invention relates to a method for storing and restoring data of a telecommunications installation, where the data are used specifically for controlling the telecommunications installation, and to a corresponding telecommunications installation.
In telecommunications installations such as exchanges, for security purposes it is common for the operator to perform a backup of the system software and the corresponding data at regular intervals, for instance at three-month intervals. A
backup is also necessary when what is known as the application program system of the respective telecommunications installation is changed. In this type of backup process, all the sofi:ware together with all work data of the telecommunications installation, which may correspond to a node of an ATM communication network, for 1 S example, is saved and stored externally on data media such as magnetic tapes.
This type of complete backup is very costly. On one hand, the complete saving of the software and work data of the application program system requires a very long time; on the other hand, a large number of data media are needed for the backup storage process, so that thc; complete saving of a network node requires more than seven hours and up to 16 tapf;s. Accordingly, the restoration of the saved sof~.vare is very time-consuming and relatively complicated given such a high number of backup tapes, since the user must always follow the order of the tape write operation in the restore operation. On the other hand, this means that the restore operation is endangered when a read error occurs during the restore operation, so that 2.5 the restoration may have to be restarted using a later backup tape record.
The result of this is that either a redundant bac;kup must be performed, which means additional consumption of tape and time, or an obsolete (or: aged] status is restored.
But the probability of a read error rises v~rith the number of magnetic tapes that are required for a backup operation.
Thus, the above described method for saving and restoring data of a telecommunications facility, whereby all the file systems of the telecommunications installation that serve the control of the telecommunications installation are physically transferred to magnetic tapes in a 1:1 ratio and are read in from said magnetic tapes, respectively, is associated with high outlay in terms of time and material, and it l0 increases the susceptibility of the backup and restore operations to errors.
It is thus the object of the present invention to lay out an improved method for saving and restoring data that are used to control the telecommunications installation and a telecommunication installation that is suitable for the method, whereby unnecessarily long run times in the saving and restoring operations are avoided, and 15 the material outlay is reduced, in order to thereby render the backup save and restore operations less prone to errors.
This object is inventively achieved by a method with the features of claim 1 and a telecommunications installation with the features of claim 7. The subclaims describe advantageous and preferred embodiments of the invention which contribute, 20 among other things, to an improved user-friendliness in the storing and restoring of the data.
According to the invention, only the software components and work data of the control of the telecommunications installation that are actually needed later in order to restore the control system -- i.e. the application program system -are saved 2:p in the backup save operation. Namely, prior to the commissioning [or:
startup] of the facility, it is specified by the software design which data of the overall data stock of the control are actually needed for a restoration of the application program system.
Advantageously, the data are transferred in the backup save operation in compressed form.
The operating personnel or the user of the telecommunications installation performs a menu-driven logical backup and restoration of the application program system, with the save operation of the backup process being logged in order to define which data have been copied onto which media. Thus, in the restoration the operating personnel of the telecommunications installation can mount (or: load] the appropriate magnetic tape for the read-in operation in a menu-driven manner with the aid of the access to the created protocol that is utilized by the software.
According to a preferred exemplifying embodiment, the above described method is further improved to the effect that in the event of a failure of the application program system, depending on thc; cause of the failure as described in the operating specifications, the operating personnel the most effective restoration variant for the particular case is selected and executed, [sic] so that, depending upon the type of missing or corrupted data, the corresponding magnetic tape on which the corresponding data were stored can be requested.
The advantages of the present invention consist in the significantly shorter run times and the reduced consumption of magnetic tapes, so that at the most six magnetic tapes are needed to back up the data of a telecommunications installation corresponding to an ATM node using the inventive method, and the backup process lasts a maximum of three hours. The present invention thus represents a departure from the physical backup/restore nnethod that is popular for PC software, with these known methods being replaced by a menu-driven logical and selective process for storing and restoring data which makes it possible to save resources (data media) and time.
The present invention can be applied to essentially any type of telecommunications installation i:n which the control of the installation accesses a particular data stock or is accomplished by software. Preferably, the present invention is used in exchanges of ATM convnunication networks.
The present invention wily now be detailed in a preferred exemplifying embodiment with reference to the enclosed drawing.
Figure 1 shows a simplified schematic block wiring diagram of a l0 telecommunications installation in which the present invention is used; and Figure 2 shows a detailed representation of the control of the telecommunications installation shown in Figure 1.
The telecommunications installation 1 serves for switching voice, image, texa and data connections between the subscribers that are allocated to the :.5 telecommunications installation 1. The telecommunications installation 1 preferably works digitally; i.e., a digital transmission of information takes place in the telecommunications installation.
As central components, the telecommunications installation 1 comprises a digital coupling arrangement (switching network) 4, which represents the actual a0 switching equipment of the telecommunications installation 1. The switching network 4 makes possible what is known as a space transfer from one transmission line that is connected to the telecommunications installation 1 to another transmission line, as well as what is known as <~ time transfer from one transmission channel to another. The digital switching network 4 is usually divided into individual coupling a5 network modules or coupling stages.
Various subscribers and transmission lines are allocated to the telecommunications installation 1, which are led to the digital switching network 4 via line adapters 2a-c. If necessary, an analog/digital conversion occurs in the line adapters 2a-c in the inbound direction, and a digital/analog conversion occurs in the 5 outbound direction. The line adapters 2a-c can be connected to the digital switching network 4 via PCM transmission lines, which have 64 channels, for instance.
For the sake of simplicity, Figure 1 shows several subscriber lines 3 for the line adapter 2a only, which lines may be allocated either to analog and digital subscriber terminal units or to additional network nodes. Naturally, the line adapters 2b and 2c are also connected to a plurality of subscriber lines 3.
The telecommunications iinstallation 1 is program-controlled. This is accomplished with the aid of a control 5, which picks up the connection requests of the subscribers of the telecommunications installation l, executes the routing, and controls the overall telecommunications installation 1, particularly the hardware of the l S telecommunications installation. The control S is thus allocated to what is known as the application program system (APS) of the telecommunications installation 1.
Figure 2 is a detailed reprcaentation of the structure of the control S.
According to the example illustrated in Figure 2, the function of the control' is divided into two halves, which run on two separate computer systems 6a and 6b.
~',0 One computer system 6a contains the entire application program system, serves for administrative control of the telecommunications installation 1, and contains the overall [...]. The computer systenn 6a can also comprise an operator interface for communicating with the operator or the operating personnel. The second computer system 6b serves primarily for controlling the actual switching technology, 25 specifically the digital switching network 4 of the telecommunications installation l, and is necessary for running the system. The software of the computer system 6b can be restored from the computer system 6a at any time. Thus, unlike the abovementioned computer system 6a, computer system 6b is hardware-oriented and supports the switching sequences. Both computer systems 6a and 6b are provided in duplicate for security purposes, in order to avoid a collapse of the overall telecommunications installation 1 given a failure of one computer system.
The two computer systems 6a and 6b also access databases 7a and 7b, respectively, which comprise the software 8a and 8b for the respective computer system and work data 9a and 9b, respectively. It is thus guaranteed that a consistent l0 data stock is present on the computer systems 6a/6b at all times. In particular, the software and the data of the computer system 6b can be restored at any time by downloading from the computer system 6a. The control S thus contains the database 7a, the software 8a, the work data 9a, and what is known as the application program system of the telecommunications installation 1, and it is therefore sufficient to 1 S perform a backup on data media 11 (e.g. magnetic tapes) at regular intervals. A
backup is also necessary with eaclh changing of the application program system.
To reduce the number of nnagnetic tapes 11 and the amount of time that are required for the backup and restoring operations, it is inventively proposed that the components of the data stock of the application program system which are actually c.0 required for a recovery of the application program system be specified prior to the commissioning of the telecommunications installation 1. This can be accomplished in the form of control information, for instance, which are stored together with the work data 9a and which are accessed by the control computer 6a with every backup operation. In particular, it is possible to realize this specification in the software 25 design. If a backup of the application program system (APS) is to be performed, the computer 6a serving for control provides that only the data of the data stock 7a that were defined beforehand are copied onto the magnetic tapes 11, which data were determined to be indispensable for recovering the application program system.
In this way, it is ensured that only the software components 8a or work data 9a that are actually needed later for recovering the application program system are stored externally, while empty and redundant data areas, which are frequently extensive, are not copied onto the magnetic tapers 11, so that time and storage material can be saved in the backup process (and later in the restoring process, accordingly).
The backup process is accomplished by an actuating of a magnetic tape drive '.0 13 by the computer 6a, whereby the magnetic tape drive serves for copying data of the application program system onto the magnetic tapes 1 l, on one hand, and for loading previously recorded data into the telecommunications installation 1, on the other hand. To further reduce the memory requirements for the backup, the data can be compressed prior to the backup by the computer 6a, i.e. the magnetic tape drive 13, and cam be decompressed following restoration.
The computer 6a logs the backup process; i.e., a log l0a defining which data of the application program system were copied onto which data medium (i.e.
which magnetic tape 11) during the backup process is created in the data stock 7a.
In the restoration process, the computer Eia can thus determine which magnetic tapes 11 are required for the restoration of the application program system and in which order these magnetic tapes 11 must be read by accessing the log 10a, so that in the restoration process the computer 6a can automatically request the required magnetic tapes 11 in the correct order for the read-in. The communication with the operator or the operating personnel is accomplished therein via a monitor 12 of the computer 6a.
Acoustic communication is also imaginable.
A particular advantage of the telecommunications installation 1 represented in Figure 2 is that, given a failure of the application program system, the most favorable restoration variant for the respective case can be executed by the computer 6a, which can be graded by the cause of the failure. Thus, depending on which data of the data base 7a of the application program system are missing or corrupted, the operator can determine from the operator statement which magnetic tapes 11 are required for the recovery of these missing or corrupted data and can mount them accordingly. It is checked whether the mounted ma;;netic tape matches the selection that has been made. Thus, if only a small volunne of software 8a or work data 9a is damaged, the I 0 restoration of these data areas can be accomplished in a significantly shorter time than previously.
The abovementioned backup and restoring method also guarantees a restoration of the data stock 7b of the computer system 6b, i.e. restoration of the control software 8b and the work data 9b.
