4 shows a graphical code according to an embodiment of the invention.

5 shows a graphical code according to an embodiment of the invention.

2 shows a mobile subscriber unit 200 according to an embodiment of the invention.

The mobile subscriber device 200 has a screen 201 , a store 202 , a microprocessor 203 , a keypad 204 and an antenna 205 which are coupled together and in particular configured to enable communication with other mobile radio user equipment by means of a mobile radio communication network.

The mobile communication network (and correspondingly the mobile user equipment 200 ) is, for example, according to the GSM (Global System for Mobile Communications) standard, the GPRS (General Packet Radio Service) standard, the UMTS (Universal Mobile Telecommunication System) standard or the EDGE (Enhanced Data Rate for Global Evolution) standard designed.

The mobile subscriber device 200 also has a digital camera module 206 on, for example, has a lens which is provided on the back of the mobile subscriber unit.

The digital camera module 206 is with the store 202 and the microprocessor 203 and allows you to capture digital images stored in memory 202 can be stored and by the microprocessor 203 can be processed.

In particular, by means of the digital camera module 206 recorded graphical codes who that by means of the microprocessor 205 processed as explained below.

3 shows a flowchart 300 according to an embodiment of the invention.

By means of a mobile subscriber device, as with respect to 2 is set up and configured, is in step 306 a digital photo of a two-dimensional barcode 302 created.

The barcode 302 is according to 4 designed.

4 shows a graphic code 400 according to an embodiment of the invention.

The graphic code 400 represents information which in particular has an application identification (application identification) in the form of the value 23 and an action identification in the form of the value 1.

For the application identification and the action identification, a total of three bytes are provided, which are of the graphic code 400 , which in this example is designed as a two-dimensional barcode, can be defined (at the beginning of the graphic code 400 ). The format of the application identification and the action identification is defined, for example, according to Table 1. Length in bytes Area Application ID 2 0-65535 Action ID 1 0-255 Table 1

Thus, the graphic code 400 Specify one of 65536 computer applications and define one of 256 application-specific actions for the specified computer application. Overall, the graphic code 400 specify one of 16777216 different actions.

To ensure backward compatibility with conventional barcodes, the graphical code shows 400 , which is extended to conventional bar codes by the specification of an application identification and an action identification, has a fixed appendix, that is, the last five bytes of the graphic code. In this example, the attachment consists of the characters? # Followed by the 3 bytes for application and action identification. The appendix is corresponding to the graphic code 400 coded. By means of the appendix, the mobile radio subscriber device can 301 notice that the graphic code 400 actually specifies an application identification and an action identification, thereby avoiding the mobile subscriber unit 301 misinterprets a conventional graphic code, ie a graphic code which does not specify application identification and action identification, and forwards the information specified by the graphic code to a computer application which is not intended for its processing. A conventional subscriber device, ie a subscriber device that can not interpret the application identification and the action identification, will pass the code contained in the code, for example, to a browser computer program. Due to the nature of the attachment, the application identification and action identification of the string is not evaluated by the browser computer program and thus the correct WWW address is used.

In this example, the graphic code specifies 400 a total of one piece of information 303 which corresponds to the string http://www.infineon.com/cgi/ecrm.dll/jsp/home.do?|and=EN?#231.

The information 303 will be in step 307 from the mobile radio user equipment by decoding the digital photo of the bar code 302 determined.

In step 308 checks the mobile subscriber device 301 whether the information 303 has the attachment and, using the application identification and the action identification, identifies those from the barcode 302 specified computer application and that of the barcode 302 specified action to be performed by the specified computer application.

The assignment of the application identification to a computer application and the assignment of the action identification to an action to be performed by the computer application are in an allocation table 304 in the mobile subscriber unit 301 saved.

So can the barcode 302 specified information 303 , which in this example contains a WWW address, can be assigned to a corresponding computer application.

The barcode 302 Thus, it may also contain other, any information that the mobile user equipment 301 using the application identification and the allocation table 304 correctly assign a computer application that can or should process the information.

The assignment table 304 is divided into a global, fixed area and a freely definable area. A corresponding division of the application identifications takes place in this embodiment according to Table 2. Application ID applications ID value from ID value to Number of IDs Globally defined area standard applications 0 49152 49153 Freely definable area proprietary applications 49153 65535 16383 Table 2

By means of the freely defined area of the allocation table 304 or the application identifications, the manufacturer of the mobile radio user equipment 301 and / or the user of the mobile radio user equipment 301 Barcodes user-defined benefit. For example, the mobile subscriber device 301 operated, configured or controlled using appropriate computer applications.

For example, the manufacturer of the mobile subscriber device 301 provide a special configuration computer application, their assignment to an application defined by the manufacturer of the manufacturer in the freely definable area of the allocation table 304 is stored. In this way, the mobile subscriber unit can be configured using bar codes specifying the predetermined application identification.

Under Using a barcode that has a fixed defined application identification, d. H. an application identification from the global, firmly defined Range, specified, can be started and a standard application to be controlled.

In this example, the barcode specifies 302 a standard application, namely a browser computer program 305 associated with the application identifier 23.

In step 309 becomes a processing unit of the mobile user equipment 301 For example, the microprocessor 203 so controlled that of the in the information 303 contained application identification specified computer application, the browser computer program 305 , is executed and that of the in the information 303 action ID specified action is performed by the computer application.

The of the barcode 302 specified action identification specifies in this example that of the barcode 302 specified WWW address from the browser computer program 305 should be used to load the specified WWW page. Accordingly, after the mobile subscriber unit 301 this action associated with the action identification using the assignment table 304 has determined the WWW page in step 310 loaded.

In the following, another example of the specification of a computer application and an action to be performed by the computer application will also be described with reference to FIG 3 , explained.

In the following example is the barcode 302 according to 5 designed.

5 shows a graphic code 500 according to an embodiment of the invention.

The graphic code 500 specifies a business card with the information listed in Table 3. Surname Frank Mustermann Street Poststrasse 5 Postcode 99999 place Musterhausen phone + 49-9999-8888 mobile phone +49 country Germany E-mail address frank.mustermann@mustermann.de Table 3

Further, the graphic code specifies 500 the computer application "Organizer" by means of an application identification in the form of the value 22 and the action "store business card" by means of an action identification in the form of the value 1.

The graphic code 500 is designed as a two-dimensional barcode.

As explained above, the last five bytes of the graphic code 500 ie the last five characters of the graphic code 500 specified string, an attachment whose first two bytes are the version of the graphic code 500 indicate and in particular signal that the graphic code 500 compared to a conventional barcode is extended by an application identification and an action identification.

The three bytes of the graphic code following the appendix 500 specify the application identification and action identification.

By means of the digital camera of the mobile radio user equipment 302 becomes the barcode 302 photographed and the thus created digital photo is sent to a device of the mobile radio user equipment 302 forwarded to reading (analyzing) the barcode. The device for reading the barcode converts the digital photo into a character string, recognizes in particular from the appendix that it is a barcode which contains an application identification and an action identification and determines it by means of an allocation table 304 , which in this example is designed according to Table 4, the specified computer application (Organizer) and the specified action (save business card). Application ID application Action ID action 0 browser 0 Call URL ... 22 Organizer 0 Save appointment Organizer 1 Save business card ... 49153 Cell Configuration Utility 0 Ringtone standard Cell Configuration Utility 200 Incognito out Cell Configuration Utility 201 Incognito ...

Table 4 shows the distribution of the allocation table 304 in a first, manufacturer-specified range (corresponding to rows 2 to 6 of Table 4) and a second, user-definable range (corresponding to rows 7 to 10 of Table 4) clearly.

The corresponding division of application identifications the division according to the table Second

In particular, it can be seen that, for example by the user of the mobile radio user equipment 302 , the application identification 49153 customizes a configuration program for the mobile subscriber unit 302 was specified. In addition, assignments of action identifications (values 0, 200, 201) to functions of the configuration program were specified (see lines 6 to 8 of Table 4).

In In this case, the application identifier (value 22) is in the first one Find area and specify the default application "Organizer" and the action identifier (value 1) specifies the action "Business Card save "(see Line 5 table 4).

Accordingly, the mobile subscriber device starts 301 the computer application "Organizer" forwards the business card data (according to Table 3) to the computer application. The computer application is instructed to execute the "save business card" command.

The Computer application then saves the business card data in the address book provided by the computer application.
