Abstract

The remote access arrangement (2) is esp. a central computer with an arrangement for establishing an Internet connection to a remote computer (1) and an arrangement for releasing a connection of the device to the target computer (5) in response to the establishment of the Internet connection and for sending a call signal to the target compouter. An Independent claim is also included for a method of remote access to a target computer.

Description

The invention relates to a method and a device for remote access to a target computer.

It is known to use so-called unified messaging systems, i. H. Information such as faxes, emails etc. are sent to a special address or fax number of a unified messaging provider sent there there is a kind of virtual office for every customer. With that, every fax or email stored on the server of the provider of this service, Such a fax or email can then be sent via the Internet with a corresponding password can be accessed from anywhere. The disadvantage of these systems is that every fax or email is sent to the special address or fax number of the provider must be sent - everyone must will provide this new email address or fax number, although the most users already have an email address or fax number. If a fax arrives, it is not directly B. in the user's office received and printed out but at the service provider, there some have notification or Forwarding options, however, is a certain delay mostly unavoidable. In addition, however, you usually need it outside the reach of your own computer, not just received faxes and emails, mostly you need a certain file, a table or a database file d. H. it would be beneficial on the go to the access to the entire computer or its data as if it were you can operate it directly. For this problem are already Known solutions. So-called. ras (remote access systems) enable the complete access to a remote computer using e.g. B. one Telephone connection, d. H. you choose z. B. using a mobile computer  the remote computer and is therefore connected to this computer and can now perform all functions as in a network control or monitor the computer. The disadvantage here is one that always has a phone connection to the remote computer Must exist, this can e.g. B. from abroad to Germany very much cause high costs; secondly, the computer has to the remote computer is to be accessed, the appropriate one Have installed software and with a telephone or cellular network be connected. And not always B. with a mobile computer appropriate software available.

The invention has for its object a novel versatile To provide remote access methods and a device for this, which without the disadvantages of almost any possible described above Location allows access to your own computer. This Task is procedurally by the in claim 1, and device according to the invention defined in claim 10 solved. Advantageous further developments and refinements of the Invention are described in the subclaims.

In principle, the invention is that of a remote Computer connected to a user by a user central computer of the user, and this then the Connect to a target computer triggers the data of the Target computer changed by control signals from the remote computer while the changed data is being transferred.  

It is advantageous to trigger the connection via a telephone line send a call signal to the target computer.

It is also beneficial if the target computer responds to the Call signal establishes the connection to the central computer, especially by taking off the telephone corresponding process.

It is also beneficial if the target computer responds to that Call signal of the central computer another call signal to the central computer, which sends in response to the further Call signal establishes the connection to the target computer, in particular by a corresponding to the lift at the telephone Process.

It is also advantageous if, before triggering the connection of the central computer with the target computer in response to the build the Internet connection through the central computer a password from remote computer must be transmitted to the central computer.

Furthermore, it is advantageous if after transmitting the password one can only be used once for each triggering of the connection Transaction number from the remote computer to the central computer must be transmitted. This transaction number is random generated number combination, which z. B. from the central computer generated and transmitted to the user, and only for one Connect can be used and thus further increase security can.  

Another benefit is when the target computer responds to the Call signal is switched on.

It is also advantageous if selected files of the target computer can be transferred to the remote computer.

It is also beneficial to move the files from the target computer to the central computer and can be stored there. To explain the invention in more detail, a Described embodiment. It shows:

Fig. 1 is a block diagram of a system for performing the method according to the present invention.

In Fig. 1 a block diagram is shown, the blocks represent useful means for carrying out the method steps.

Block 1 symbolizes a remote computer ( 1 ), which can establish a connection to the central computer ( 2 ) directly via the Internet page of a central computer ( 2 ) shown on the remote computer ( 1 ). The central computer ( 2 ) can carry out security checks on the website of the central computer ( 2 ) shown on the remote computer ( 1 ) by means of a user name and / or password query in order to control access. After access has been granted, the central computer ( 2 ) connected to a telephone network triggers a telephone connection via a central modem ( 3 ) and dials the telephone number of the target computer ( 5 ) which is also connected to the telephone network, and the latter can now establish the connection directly produce by accepting the telephone connection initiated by the central computer via a modem ( 4 ) or in turn initiating a telephone connection to the central computer ( 2 ) after receiving the call signal from the central computer ( 2 ) by using the telephone number via the modem ( 4 ) of the central computer ( 2 ) dials and this establishes the connection by accepting the call signal from the target computer ( 5 ). Now all control signals from the input devices such. B. a mouse ( 11 ) of the remote computer ( 1 ) and a keyboard ( 6 ) of the remote computer ( 1 ) via the Internet connection to the central computer ( 2 ) and from there via the telephone connection by means of the central modem ( 3 ) and the Transfer modems ( 4 ) to the target computer ( 5 ). The image data displayed on a monitor ( 7 ) of the target computer ( 5 ) are continuously transmitted by the target computer ( 5 ) via the modem ( 4 ), at the latest after a change or after a predetermined time interval after a change, or after a predetermined number of changes the telephone connection via the central modem ( 3 ) to the central computer ( 2 ) and finally to the remote computer ( 1 ). The same data is displayed on the website displayed on the remote computer ( 1 ) as on the monitor ( 7 ) of the target computer ( 5 ). Unrestricted control of the target computer ( 5 ) is thus possible from the remote computer ( 1 ). That is, From the remote computer ( 1 ), the mouse arrow displayed on the monitor ( 7 ) of the target computer ( 5 ) can be controlled by moving the mouse of the remote computer ( 11 ). The movement of the mouse arrow displayed on the monitor of the target computer ( 7 ) or the data that changes as a result are transmitted immediately after the mouse movement begins, ie after the smallest change in the data displayed on the screen, these become the remote computer ( 1 ). transferred and displayed there. This enables full control of the target computer ( 5 ); for example, a document can be created in the target computer ( 5 ), which is entered on the keyboard of the remote computer ( 1 ). Furthermore, it is possible to specifically access individual files of the target computer ( 5 ) and transfer them to the remote computer ( 1 ). B. is loaded from the hard disk of the target computer ( 5 ) and the data of the file is stored by means of the modem ( 4 ) over the telephone connection and the central modem ( 3 ) to the central computer ( 2 ) and there either (for later retrieval), or transmitted to the remote computer ( 1 ) via the Internet connection and can be stored or edited there, for example. In addition, after the connection between the central computer ( 2 ) and the target computer ( 5 ) is established in the central computer ( 2 ), a time counter (not shown) begins to run until the connection is interrupted again. The time counter data are also stored in the central computer ( 2 ) and, if necessary, transmitted to the remote computer ( 1 ) and displayed there.
