This object is achieved according to a first aspect of the invention by a communication system comprising:

• - At least one user-to-lead telecommunication device comprising a transmitting device and a receiving device, and a display device for reproducing a signals received via the receiving device, generated image, wherein the transmitting device is operated such that it transmits at least in phases a signal sequence for the telecommunication device is specific, and

• - Wherein, depending on the fulfillment of this distance criterion, a data transmission to the user-to-leading telecommunication device is caused.

Thereby will it be possible Persons in public and in private rooms Make or identify actions effectively at least classify as a communication partner. The invention Use this one when using common cell phones occurring side effect of the field strength attenuation to generate a Dialog criterion. By the solution according to the invention, it is possible in particular, so-called "local based services "especially offering people within a relatively small Detection area sharply detected and thus in one for this Whereabouts meaningful data exchange can be included. After that become them, z. B. transmitted to the mobile phone, messages or identifiers, to which the users can react. By the inventive concept is it is possible in an advantageous manner without special content-specific filters the tide at unwanted Suppress messages, and only provide information to the user for this because of the fulfillment an approximation criterion at least with high probability make sense. By the inventive concept In particular Bluetooth and WLAN connection concepts be used in addition to the mobile phone in the same device to be provided. It is possible, To use these connection concepts on the device, a system setting make that leads to that a user at least in a certain area only such Information receives its transmission due to the fulfillment of a Site criterion by the user makes sense, for. B. if a Person using her mobile phone in the reach of an information services offering zone comes.

The inventive concept offers in particular a cost-effective Alternative to GPS-based positioning systems that do not provide adequate, enable motor-coordinated selection by the user. Furthermore It is the system of the invention possible, even in a zone within which there are several persons, meaningful data streams sure. This is just at busy points an advantage because the erfindungemäße concept the unwanted response and thus avoiding miscarriages.

The Invention solves the task given at the outset by providing a technique which makes it possible that a person in a given room with the help of a selective Action triggers a trigger. By this triggering can be directed in particular by a directed to the mobile phone Query an identification of the person done.

If a person carries a mobile phone with him, it is possible with the Bluetooth device (client) to address the latter using at least one host. The Bluetooth device will then turn on its transmitter and transmit the possible radio services. The transmission energy of a client required for this can be measured and proven as field strength in numerous variants. As radio waves fade in the square of the distance, it is possible to determine how close a person z. B. at one, activated by her trigger point, which z. B. is acted upon by at least one Bluetooth host. This is necessary because the service request of a bluetooth host responds to all devices within a radius of about 10 meters and these then report. The invention uses in a surprisingly advantageous manner, the actually disadvantageous side effect that surrounding the trigger point clients with the trigger point with apply different signal intensity and just the client closest to the trigger point (eg mobile phone user) has the highest measurable transmission field strength, since this is closest to the trigger point, if there is also the antenna of the Bluetooth query or an external field strength meter. Using a database connection, the data contained in the Bluetooth telegram can be assigned to a person safely.

The triggering

Under Triggering is the action of a person in the present context understand that is approaching or touching a certain point. The approach can by walking, setting, lying, jumping, waving, etc. happen. For this purpose, the invention is designed with a proximity circuit, at a certain distance the Bluetooth according to the invention Host is activated and a query is initiated. Report to me all Bluetooth detectable (and unlocked) Bluetooth devices, such as they are present in mobile phones, PDAs, etc. Because the messages arrive one after the other, it is possible for each message the Determine reception field strength and thus at the trigger point next User. For the determination can be both the Bluetooth internal field strength measurement method (strength) as well as an external field strength meter used become. This is for example from a selective circle (parallel resonant circuit) and a modulator (eg, diode) and a filter. For others Radio systems, z. WLAN / BLUETOOTH, a similar implementation may be provided become. There are also circuits for power measurement (PWR metering) available, so that a circuit implementation of the invention easily possible in various variants is. Triggering a search query may be unconscious by the user or done consciously by crossing a zone or a billboard or a product (store shelf), etc., or objects. For this the invention provides sensors that only when touched a start the corresponding radio search query. It is also possible with the volitional actions between the mere touch (touch) and activity, (power exercise) differ. In particular, holding forces are a measure of the desirability, what a Advertisers the security that the consumer for a particular Product especially interested in handling or holding it.

A first exemplary embodiment

One Java-based midlet can be downloaded to at least one mobile phone become. The task of this little program is via Bluetooth a specific number that is also stored in a register (eg external Server), to send on request. At the same time this program from at least one external server outgoing messages, Texts, pictures, voice and sound information etc. on the mobile phone. Preferably, the Bluetooth device is in a mobile phone, in which the software in question is stored, for serial data transmission set. approaches If the person now touches a trigger point or touches it, then a query about the Bluetooth host performed in such a way that one determines which one equipment allow a serial connection. These are then addressed and sign up accordingly. With the help of a specific query signal the host sends the registration code of a client. Just Equipment, who downloaded and installed this software can use it Submit code. Reaches the reception field strength a determinable level so takes the connected to the Bluetooth host Calculator connection to the server. This provides with the help of the registration number, a data or other connection, eg. B. via GPRS, to the corresponding Mobile phone and can now over the installed software informs the interested consumer to play. The server can also provide other services or call (eg call center) for the mobile phone benefit with (requested) To provide information

Another simplified method

A user is registered with his registration number (MAC = Media Access Control) of his Bluetooth device and is approaching a trigger point. This is activated by approach, touch or actuation and sends out a Bluetooth search request (= host). All activated devices in radio range send their identification / possible services. The identifier is checked and it is determined whether the person was the one closest to the trigger point (selective field strength measurement). Then, a server is informed, which makes contact with this person and possibly can communicate with the benefit itself or by a third party via the mobile phone. As a special feature according to the invention, it is possible, during the reception of the expected client message, to switch off the magnetic portion of the receiver at the host and to communicate via the mobile telephone. This is useful to receive only the electrical part (alternating E-field) of the message. Since electric fields of the third power attenuate for range (as opposed to radio waves that attenuate square to distance), only one person can still be detected that is immediately in the near field of the host receiver. Thus, it is possible to have others within the coverage of a Bluetooth host (or WLAN / BLUETOOTH host) sensitive people "quasi hide" because the range of their electrical fields is not sufficient to operate the host receiver sufficient.

It offer many possibilities according to the invention to realize such a circuit design. there ranges the spectrum of possibilities Downloadable software (eg Java midlet for mobile phones) to the intended or use of the existing radio systems GPS, GSM, WLAN / BLUETOOTH, etc. provided they can be addressed by a polling circuit (host) are.

On Basis of the inventive concept it becomes possible a as adhesive label or otherwise flat-building, in particular executed printed circuit To create circuit that allows, with sufficient approximation of a Bluetooth or Wi-Fi enabled Mobile phones from the label to read an identifier the one Link to a host or other network element generated, allowing product-specific information directly to the mobile phone submitted by the user be meaningful in the context of the fact that the User with his mobile phone near the label or the microcircuit has to stand. These microcircuits can be called quasipassive circuits be trained with the carrier frequency of the Bluetooth or WLAN signal synchronize and as required of a data pattern specified in the label, a modulation of the Initiate the label input impedance so that the data pattern is transmitted directly over the Transmission device of the mobile phone is readable. This impedance modulation can be done by the over the receiving electrodes of the label detected signals through Shift registers wander, which occurs when certain register states each results in a short circuit of the receiving electrodes.

It is possible, to design the label as a circuit next to a Bluetotth or WLAN standard open interface also RFID or other transponder interfaces offers. This makes it possible in particular, the content of the part of the label for the Bluetooth or WLAN dialogue through the RFID port set.

Of the Approach state can be determined by the label circuit and as a special Information in a data telegram generated by the label circuit be involved. The intensity or the approximate state can also be determined in the area of the user device and there programmatically are processed. So it is possible the image playback on the display of the user, or the functionality a menu window switch depends on to make a certain approximation criterion Fulfills is. In particular, it is possible to control the display so that in this a color or brightness effect depends on is made how close the user to the detection label or approaching the aforementioned trigger point. It is also possible at Fulfillment of one Proximity criterion to cause a configuration of the mobile phone, for example provides a specific menu window, so related with the currently fulfilled Proximity criterion meaningful inputs can be made. These inputs can be provided by link-providing or otherwise host-based in particular. It is possible in particular at fulfillment of the approximation criterion - preferably by transmission intensity measurement checked will - that Mobile phone temporarily to confer special functional characteristics, so that this temporarily can be used in the manner of a remote control and thus z. B. Procedures behind a shop window, or coordinated on a projection screen can be.

Especially will it be possible when approaching at the trigger point to generate a link that allows under Use of the authorization mechanism of the mobile phone a personal avatar or Servant appear on a projection screen leave and over this a sequence, in particular disclosure of the to be transmitted To process information.
