Problems solved by technology

[0005] However, it has been shown in practice for self-sufficient computing units and self-sufficient sensors that the use of the above-mentioned protocols with and without a suitable compression algorithm can still be very complex and is therefore the use of wired machine-to-machine communication Known Barriers to Protocol

Embodiment Construction

[0052] figure 1 Exemplarily showing a communication message, referred to below as the first message N1, has an IP header field IPH, a TCP header field TCPH, a first header field HEA1 including data according to the standard HTTP (Hypertext Transfer Protocol) and a first header field according to The first application data field PAY1 of the OSI layer model (OSI—Open Standard Interface (open standard interface)). The concept "application data field" is called "payload" in English. The concept "header field" corresponds to the English concept "header field".

[0053] Such messages are commonly used today in machine-to-machine communication as well as in human-machine communication, for example for calling content on the World Wide Web. Those skilled in the field of communication technology are familiar enough with the concepts IP (Internet Protocol), TCP (Transmission Control Protocol) and HTTP that no further explanation is given here. The first application data field PAY1 ca...

Abstract

The present invention relates to methods and devices for establishing communications. The first communication message includes a first header field and an application data field. In this case, the first header field of the first communication message is transformed into a second header field based on the schema, wherein the second header field can be constructed on the basis of XML. In addition, the second header field is converted into the third header field using a compression method. A second communication message is formed from the third header field and the application data field. The invention can be used, for example, in machine-to-machine communication.

Description

technical field [0001] The present invention relates to methods and devices for establishing communications. Background technique [0002] Over the past few years, machine-to-machine communication, ie the exchange of messages between two computing units, has grown significantly, for example via the Internet. An application of such machine-to-machine communication involves, for example, wireless sensor networks with a large number of self-sufficient sensors. Such a self-sufficient sensor has a small computing unit with a very limited memory, for example 50 Kbytes, a battery for power supply and a wireless interface for data transmission. These self-contained sensors provide information such as temperature or air pressure, wherein this information is sent directly or indirectly (vermittelt) via a plurality of self-contained sensors to a receiving station for analysis. In academia, such self-sufficient sensors are known inter alia as MOTS. A characteristic of these self-suff...
