Description:
TECHNICAL FIELD 
     The invention concerns a process for communication between a first electrode data-processing system and a second electronic data-processing system, as well as an electronic data-processing system for communication with at least one other electronic data-processing system, with a computing unit for processing data, a memory unit for storing data, a display unit for displaying data, an input unit for inputting data, a transmission unit for exchanging data with the second electronic data-processing system, and an interface for connecting the calculating unit to the transmission unit. 
     BACKGROUND 
     Such processes for communication and such electronic data-processing systems are known from the prior art. Here it is a matter, for example, of personal computers that communicate with each other via a normal telephone line with the aid of communicating program. In this case the communication program is found in each of the computers that are communicating with each other. Thus, it is typical, for example, to exchange messages between computers via telephone lines, a program for processing, e.g. a so-called e-mail program, being installed on each computer. Beyond that, it is also necessary that these e-mail programs be such that they are compatible with each other. For additional processing of the transmitted messages in the respective computers, it is further required that the computer in question contains appropriate programs for processing the transmitted messages. These can consist, for example, of graphics- or text-processing programs. 
     Thus, in the prior art is it disadvantageous necessary that for each computer the appropriate processing programs for processing the transmitted messages or information be already available. 
     This requires, in the prior art, that these computers have relatively large storage units for storing the necessary and frequently used processing programs. Furthermore, it is disadvantageous that fixed personal computers can perform their function only at their site. Meanwhile, it is true that very capable and mobile personal computers have been developed, e.g. laptops or notebooks; however, these portable personal computers are always relatively heavy and unweidly and, because of the further-required large storage capacity, very expensive. 
     Particularly disadvantages, specifically with the portable laptops and notebooks, is the fact that these computers are always too heavy and large to be carried continuously by a user in the hand or jacket, for example during a trade fair or exhibition or a visit to a tourist attention. Precisely in this situation, e.g. during a visit to a trade fair, it would be extremely advantageous to the specialist visitor to be able to refer at any time to data that, for example, a large, fixed electronic data-processing system has available. 
     SUMMARY 
     It is therefore the task of the invention to make available a process and an electronic data-processing system, for communication with at least one other electronic data-processing system, that avoid the above-specified disadvantages and allow the user to utilize all the usual data and data-processing programs even with only small dimensions and low storage capacity of the data-processing system. 
     The task is accomplished according to the invention, in a process of the type stated in the introduction, by the fact that during an accessing of data from the second electronic data-processing system by the first electronic data-processing system, at least one processing program for processing the transmitted data is also sent. In an electronic data-processing system for communicating with at least one other electronic data-processing system according to the type stated with the introduction, this task is accomplished through an electronic data-processing system [according to claim 10]. 
    
    
     BRIEF DESCRIPTION OF THE DRAWING 
     FIG. 1 illustrates first and second electronic data-processing systems according to the present invention. 
    
    
     DETAILED DESCRIPTION 
     The advantages of the invention lie in particular in the fact that with the aid of the process according to she invention or with the aid of the electronic data-processing system according to the invention the appropriate processing program for using the transmitted data or information no longer must be kept available in the preferably portable, first electronic data-processing system. By virtue of the transmission of the processing or utility program for using the transmitted information, in each case-taking place directly before or directly after the transmission of the actual data or information, the first electronic data-processing system need only contain storage space sufficient for one utility or processing program. The storage capacity, and thus the weight and dimensions, of the first electronic data-processing system can in this manner be considerably reduced. 
     Consequently, it is possible to design the first electronic data-processing system to be light and small enough to be usable at any time by, for example, the above-mentioned trade-fair visitor, i.e., to be carried e.g. in the hand or the pocket of a jacket. 
     It is especially preferable that the processing program for using the transmitted data is likewise transmitted by the second electronic data-processing system to the first electronic data-processing system. However, it is also conceivable to transmit the processing program from a third electronic data-processing system, which, for example, is responsible only for this task. 
     It is especially preferable that, upon the accessing of the information from the second electronic data-processing system by the first electronic data-processing system, first data is transmitted by the first electronic data-processing system to the second electronic data-processing system, by means of which data the second electronic data-processing system is induced to transmit the processing program. This first data can be a matter of, for example, a command program understandable to the second electronic data-processing system, which program gives the second electronic data-processing system the command to transmit, shortly before or after the transmitted of the desired data or information, the corresponding processing program for processing and/or using the transmitted data or information. However, it is also conceivable that the second electronic data-processing system transmits to the first electronic data-processing system the corresponding processing program together with the desired date or information, automatically upon an accessing. 
     An additional preferred implementation [for] of the process according to the invention is distinguished by the fact that the first data represent an interactive program, for example an internet search program that is suitable for searching for data on the second electronic data-processing system. Here it is especially advantageous when this search program, which can be, for example, a web browser, can likewise search for and locate the processing program. 
     A further advantageous implementation form of the process according to the invention is characterized by the fact that the transmitted processing program for using the transmitted information is stored by the first electronic data-processing system only as long as necessary for the processing of the transmitted information. In this way the available storage space in the first electronic date-processing system is claimed only as long as necessary and, after the completion of the use of the transmitted data, is again free to receive new data or processing programs. Here it is of a particular advantage that the use determines, before the transmission or during the using of the transmitted data, how long the processing program is to be stored. 
     An especially advantageous implementation form of the electronic data-processing system according to the invention [in accordance with Claim 10] is distinguished by the fact the the transmission unit is detachable from the electronic data-processing system. The detachable transmission unit can be a matter of, for example, a mobile telephone or the like. This mobile telephone can be designed as active or passive. In the latter case, this passive mobile telephone is characterized with particular advantage by the fact that it is connectable to the electronic data-processing system as a plus-in module. In this case the passive mobile telephone is controlled advantageously by the electronic data-processing system, i.e. by the input equipment of the electronic data-processing system. The mobile telephone implemented as a plug-in module, which represents the transmission unit, can thus be designed especially small and light, since it must contain only those components necessary for the transmission of data, while the input and display components, which a mobile telephone normally includes, can be dispersed with. 
     A further preferred implementation form of the electronic data-processing system according to the invention is characterized by the fact that the electronic data-processing system is a portable personal computer, as for example a palmtop or notepad computer. Here is especially preferable that the input unit is implemented as a touch-sensitive viewing screen, so that the input and display units are united in the viewing screen. Thus, together with the passive, plug-in-module mobile telephone that can be designed very small, the first electronic data-processing system can be a very small notepad computer that can be easily carried in a jacket pocket or the hand and, at the same time, is not limited in its ability to process all transmitted information in a complete and user-friendly manner. 
     The transmitted information can be, for example, a city map. In that case, this city map, by means of the likewise transmitted processing and utility program, can be interactively used by the user of the portable first electronic data-processing system. Here, through the process according to the invention and/or the electronic data-processing system according to the invention, recourse can be advantageously made to the processing and utility program developed especially for this city map, since this program, according to the invention, is likewise transmitted to the first electronic data-processing system. 
     The communication or transmission of the data and programs from the second electronic data-processing system to the first electronic data processing system or the transmission of the data and programs from the electronic data-processing system to the second electronic data-processing system, as the case may be, takes place advantageously with the aid of DECT, GSM, or Ethernet systems that are standard in the prior art. 
     [Further advantageous implementation forms of the invention are specified in the dependent claims.] 
     An implementation form of the invention will be described with reference to the accompanying drawing. 
     The figure shows as a first electronic data-processing system a palmtop computer  2 . The palmtop computer  2  exhibits a housing  3 . Inside the housing are located a calculating unit  4  and a storage unit  6 , represented with dashed lines. The palmtop computer  2  is operated through a touch-sensitive viewing screen  8 , which serves simultaneously for the displaying and inputting of data. The palmtop computer  2  shows an interface  16  for the attachment of a transmission unit to be palmtop computer  2 . In the drawing a plug-in module  10  is placed upon she interface  16 . The plug-in module  10  can, for example, be further secured to the palmtop computer by means of fixing pins (not represented) that engages holes (not represented) in the palmtop computer  2 . 
     The plug-in module  10  designed as a transmission unit displays a transmitter  12  ends a receiver  14  for transmitting and receiving data. The plug-in module  10  is a passive mobile telephone that is activated and operated via the touch-sensitive viewing screen  8 . In the represented implementation form, the plug-in module  10  communicates with a transmitter and receiver  20  of a second electronic data-processing system  22  by aid of the GSM system  18 . The second electronic date-processing system  22  likewise displays a calculating unit  24  and a storage unit  26 . 
     According to the process in accordance with the invention, upon an activating by a user, through the touch-sensitive viewing screen  8 , of the plug-in module  10  designed as a transmission unit, a request is sent via the GSM connection  18  to the second electronic data-processing system  22  for the transmission of data stored in the storage unit  26  of the second electronic data-processing system  22 . Simultaneously with the transmission of the request to the second electronic data-processing system, the palmtop computer  2  designed as the first electronic data-processing system transmits, by aid of the transmission unit  10  and the GSM system  18 , to the second electronic data-processing system  22  the command to also call up the appropriate processing program from the storage unit  26  and send this to the palmtop computer  2 . Thus, in addition to she desire data, the electronic data-processing system  22  also transmits from the storage unit  26  to the palmtop computer  2  she processing or utility program corresponding to these data, by aid of the transmission and receiving unit  20  and the GSM system  18 . Thus, upon the conclusion of the communication the desired data and information are present in the storage unit B of the palmtop computer  2 , as well as the corresponding processing and utility program for processing and using the transmitted data.
