Abstract

A method and apparatus for generating and updating a remote instance of a screen view for a communication device during a communication session. The screen view has a number of data elements that are presented on the screen view in accordance with a defined static or dynamic display schema. A display schema that at least partially corresponds to the display schema of the screen view is transmitted to the communication device at least a first time via a first communication path, the values of at least one of the data elements are transmitted to the communication device via a second communication path during the communication session, and the values of the data elements and the transmitted display schema are combined by the communication device in order to display the remote instance.

First claim

The invention claimed is:

1. A method for generating and updating a remote instance of a screen view for at least one communication device during a communication session, comprising:
a number of data elements presented on the screen view in accordance with a defined static or dynamic display schema;
a display schema that at least partially corresponds to the display schema of the screen view transmitted to the communication device at least a first time via at least one first communication path;
values of at least one of the data elements transmitted to the communication device via at least one second communication path during the communication session;
wherein the transmitted values of the data elements and the transmitted display schema are combined by the communication device in order to display the remote instance; and
communication over the second communication path takes place via a broker and is executed in accordance with a protocol which functions in accordance with a subscriber/publisher model.

2. The method according to claim 1 , wherein the screen view comprises a display of a computer unit which serves to control an installation of a user.

3. The method according to claim 1 , wherein at least one of the number of data element represents data of the telemetry level.

4. The method according to claim 1 , wherein data transmission over the second communication path is encrypted.

5. The method according to claim 1 , wherein at least the second communication path defines a reverse channel.

6. An apparatus for making available a remote instance of a screen view for display on a communication device, comprising:
wherein a computer unit on which the screen view is displayed, the computer unit having at least one first communication path and at least one second communication path to the communication device;
a number of data elements presented on the screen view in accordance with a defined static or dynamic display schema;
a display schema that at least partially corresponds to the display schema of the screen view transmitted by the computer to the communication device at least a first time via the first communication path;
values of at least one of the data elements transmitted to the communication device via the second communication path during a communication session;
wherein the computer unit accesses the first communication path via a network interface and accesses the second communication path via a security controller; and
the security controller executes the communication via the second communication path according to a protocol which functions in accordance with a subscriber/publisher model.

7. The apparatus according to claim 6 , wherein the second communication path feeds from the security controller via a broker.

8. The apparatus according to claim 6 , wherein the security controller has an encryption and decryption unit.

9. The apparatus according to claim 6 , wherein a plurality of instances of the data elements, depending on an authorization, are transmitted selectively to the communication device.

10. A software product embodied on a non-transitory computer medium which can be executed by a communication device for displaying a remote instance of a screen view displayed on a remote computer unit, comprising:
at least one first communication path and at least one second communication path connecting the communication device to the computer unit;
the software product enables the communication device to execute at least the following:
reception of a display schema that at least partially corresponds to a display schema of the screen view via the first communication path;
reception of values of data elements via the second communication path during a communication session is with a broker and in accordance with a protocol that functions with a subscriber/publisher model;
combination of the received display schema and received values of the data elements to form the remote instance of the screen view; and
display of the remote instance.

11. The software product according to claim 10 , wherein the software product further enables the communication device to transmit data values to the remote computer unit via the second communication path.

12. The software product according to claim 11 , wherein the data values are entered by a user via a user interface of the communication device.

13. The method according to claim 1 , wherein at least one data element of the number of data elements represents measured data from measuring sensors.

14. The method according to claim 1 , wherein the transmitted display schema corresponds to a subset of the display schema of the screen view, based on authorization.
