Description

Technical area

The The invention relates to a communication system and a method for Production of communication connections according to the preamble the claims 1 or 17.

conventional Systems for the production of communication connections, in particular of telephone communication links, in a fixed or a Radio network have switching equipment. The communication links are while real-time connections between predetermined terminals; the Connection is via at least a switch.

Allow radios Communication connections on a predefinable frequency. These communication links However, they are only possible within the transmission range.

outgoing From this prior art, the invention is based on the object a communication system and a method of the aforementioned To create a way to achieve extended usability.

These The object is achieved with the features of claims 1 and 17.

The The invention is associated with a plurality of advantages.

In the system according to the invention after receipt of a first message, this first message or a second message that generates in response to the first message is, at least one further terminal with a terminal-individual Transmitting device without the interposition of a switching device sent between the second and the other terminal. The system is needed no switching device. Each terminal "intercepts" messages from another terminal locally near is on, and passes these messages on to other devices, if these are close come. The messages are transmitted in this way unlimited (Passed). The forwarding terminals realize so under the function of intermediate stations.

The Among other things, messages can be transported over any distance, that the terminal cached a received message and with by its operator is transported to another location. This is the sphere of influence of the system expanded virtually indefinitely without any of it Auxiliaries such as exchanges required.

The inventive system is also characterized by the fact that no costs for the construction, Care and maintenance of switching equipment are spent. About that In addition, the system according to the invention operates independently of potential Errors or even failures of switching equipment.

For the user the system according to the invention offers this noticeable Advantages. He is able to communicate despite the limited range of his terminal practically over to send and receive any distance, and this too comparatively extraordinary low cost. At best, namely, reduce themselves for the User costs for participation in the system on the pure operating costs of his Terminal. The in conventional System costs for network operation and agency services fall within the system of the invention advantageously not on.

The inventive system allows the Localization of terminals or terminal users, the specifiable criteria (e.g., business partner, purchaser / seller, member of a club). His mode of operation is independent of Actions of system users, such as the operator of a terminal which forwards a message in the system. This results in the further advantage that the system can be used in emergency situations can, in which the terminals because of an accident is no longer able to operate his terminal.

The Invention allows not just a communication of people on a random basis, to Example of people passing each other, but also the communication with persons who have specifiable attributes.

The inventive system can also be for demoscopic Surveys and in the entertainment area (board games) use.

The The invention will now be described with reference to the figures.

It shows

1 a first embodiment of a communication system according to the invention, and

Preferably, the messages are encrypted.

One terminal T1, T2, Tx has at least one transmitting device T1RC, T2RC, TxRC , optionally a control unit T1C, T2C, TxC, a memory device T1MEM, T2MEM, TxMEM, a data input device T1IN, T2IN, TxIn and / or a data output device T1OUT, T2OUT, T2OUT for output of data in acoustic, optical and / or tactile form. Furthermore, a terminal have a further transmitting device, the data in electronic Form transfers.

The terminals can in particular mobile telephone terminals or portable data processing equipment be.

the Control equipment (e.g., T2C) of a terminal (e.g., T2) is a control program assigned, which is designed in such a way that after reception a first message N1 this first message N1 or a second Message (N2) depending on the first message N1 is generated, at least one more terminal Tx is sent.

Possibly the second message is only after a caching of the first message N1 in the memory device (e.g., T2MEM) of the memory device the first message N1 received terminal (here: T2) to the other terminal (Tx) sent.

The The first and second messages N1, N2 preferably each contain one Address of its originating message terminal T1. Will be the first message N1, e.g. formed in T1, N1 is given the address of T1. About that can be provided that the messages forwarded in the system in each case the addresses of terminals of the included in the communication connection terminals included. It can the addresses of all these terminals or only part of these addresses are included in the messages become.

Especially becomes the second message N2 depending on the first message N1 and depending a first information I1 formed. This first information I1 is in the second terminal T2 stored, is there (for example, instantaneous value of the terminal supply voltage) or becomes the second terminal T2, e.g. with the message N1, fed.
