Description

Field of the invention

Exemplary embodiments of the invention relate to the detection of a radio interference signal and / or an interfering transmitter.

Background of the invention

• an apparatus according to the second aspect of the invention.

The disclosures of the first aspect, the second aspect and the third aspect of the invention correspond to one another. For example, a radio communication device (e.g. the first radio communication device and / or the second radio communication device disclosed below) in the method according to the second aspect of the invention may be a radio communication device according to the first aspect of the invention. Likewise, the remote device in the method according to the first aspect of the invention can be a device according to the second aspect of the invention. Accordingly, the disclosure of a feature disclosed for one aspect of the invention - insofar as it makes sense - is also intended to apply as a disclosure of a corresponding feature of one or more of the further aspects of the invention.

The properties of the methods, the devices, the computer programs and the system according to the aspects of the invention are described below, in some cases by way of example.

A utility vehicle is to be understood as meaning, for example, a truck, a trailer or a semi-trailer (in particular a trailer or a semi-trailer). Such commercial vehicles are intended in particular for the transport of goods, preferably piece goods, in public road traffic. For this purpose, the commercial vehicles have different types of superstructures which are used to accommodate the goods to be transported in a loading space. For example, box bodies with fixed side walls and a fixed roof are known which enclose the cargo space. Since the box bodies are closed, box bodies are particularly suitable for the transport of moisture-sensitive and / or temperature-sensitive goods for example suitable for so-called dry transport and / or refrigerated transport. In addition to box bodies, so-called tarpaulin structures are also known in which the side walls and the roof are closed by at least one tarpaulin. In the case of tarpaulin structures, the front wall is usually designed as a solid wall, while the rear wall is regularly formed by two wing doors in order to load the cargo space from the rear if necessary. If a tarpaulin can be moved along the side wall, it is also known as a curtainsider.

A radio signal is used, for example, to transmit information. Such a radio signal is obtained, for example, by a modulation method (e.g. amplitude modulation, amplitude shift keying or frequency shift keying) in which a useful signal that contains the information to be transmitted in coded form is a so-called carrier signal (e.g. with a predetermined frequency or with a frequency in a given frequency band) changed (ie modulated).

In contrast to this, a radio interference signal is used, for example, to prevent the transmission of information by a radio signal, for example by preventing the radio signal from being received. For this purpose, the radio interference signal is transmitted, for example, by a jammer with the same frequency as the carrier signal of the radio signal or with a frequency in the same frequency band as the carrier signal of the radio signal, so that the radio interference signal is superimposed on the radio signal within a coverage area of the jammer in such a way that the Reception of the radio signal is prevented. Accordingly, the coverage area of the jammer should be understood to mean, for example, the area in which the radio interference signal prevents the radio signal from being received. For example, this superposition leads to such a reduction in the signal-to-noise ratio (eg a reduction in the signal-to-noise ratio to a value less than or equal to 10 dB) within the coverage area of the jammer that the reception of the radio signal is not possible; and in the vicinity of the jammer, but outside the coverage area of the jammer (e.g. in an area bordering the edge of the coverage area), the reception of the radio signal may be possible, but (e.g. due to a reduced signal-to-noise ratio there, e.g. a reduction of the signal-to-noise ratio to a value in the range 10dB to 15dB). It goes without saying that an interfering transmitter can emit several radio interference signals (for example simultaneously and / or on different frequencies and / or in different frequency bands).

A radio signal parameter is, for example, a parameter that defines a (e.g. physical) size and / or property of a radio signal such as a signal-to-noise ratio, a signal-to-interference ratio, a received field strength, the presence of non-synchronizable carrier frequencies, a bit error rate or a Connection termination rate represented qualitatively or quantitatively.

The detection of a radio signal parameter (e.g. the first radio signal parameter) or a change in the radio signal parameter (e.g. the first change in the radio signal parameter) can for example be based at least in part on a received radio signal (e.g. through a wireless communication interface, e.g. a wireless communication interface in the form of a radio interface). For example, the detection of such a radio signal parameter can include measuring and / or determining the size and / or property of the received radio signal represented by the radio signal parameter. The detection position at which the radio signal parameter was detected should be understood to mean, for example, the position at which the radio signal was received.

In order to detect a change in the radio signal parameter, several successive radio signal parameters can be detected, for example in that the measurement and / or determination of the size and / or property of the radio signal received in each case, represented by the successive radio signal parameters, is carried out continuously or repeatedly. A change in the radio signal parameter should accordingly be understood to mean a qualitative or quantitative change in the size and / or property of the radio signal, which is represented by (e.g. two) radio signal parameters detected consecutively and / or in a predetermined time interval. The detection position at which the change in the radio signal parameter was detected is to be understood as meaning, for example, the detection position of the last (i.e. most current) radio signal parameter of this radio signal parameter.

A radio signal parameter characteristic of a radio interference signal (e.g. the first radio signal parameter) should be understood to mean, for example, a radio signal parameter that is characteristic of whether the reception of the radio signal at the detection position (e.g. the first detection position) at which the radio signal parameter was detected by a Radio interference signal is impaired (e.g. made more difficult). Likewise, a change in a radio signal parameter that is characteristic of a radio interference signal (e.g. the first change in the radio signal parameter) should be understood to mean, for example, a change in the radio signal parameter that is characteristic of whether the radio signal is received at the detection position (e.g. the first detection position). at which the change in the radio signal parameter was detected is impaired (eg made more difficult) by a radio interference signal. Accordingly, a radio signal parameter characteristic of a radio interference signal (e.g. the first radio signal parameter) or a change in a radio signal parameter characteristic of a radio interference signal (e.g. the first change in the radio signal parameter) should make it possible to determine, at least in part, based on whether the reception of the radio signal at the respective detection position ( e.g. the first detection position) is impaired (e.g. difficult) by a radio interference signal.

In order to determine whether the reception of the radio signal at the respective detection position is impaired (e.g. made more difficult) by a radio interference signal, the rules can, for example, specify for which radio signal parameter or for which change in the radio signal parameter it should be determined that the reception of the radio signal is on the respective detection position is impaired (eg difficult) by a radio interference signal. For example, the signal-to-noise ratio drops when a radio signal is superimposed on a radio interference signal, so that, for example, it can be specified that for a change in a radio signal parameter in the form of a decrease in the signal-to-noise ratio by more than a specified signal-to-noise ratio -Distance difference threshold value (e.g. within a predetermined period of time or between two successively detected radio signal parameters) or for a radio signal parameter in the form of a signal-to-noise ratio that is less than a predetermined signal-to-noise ratio threshold, it should be determined that the reception of the radio signal is on the respective detection position is impaired (eg made difficult or prevented) by a radio interference signal. It goes without saying that the determination of whether the reception of the radio signal at the respective detection position is impaired (e.g. made more difficult) by a radio interference signal, for example part of the detection according to the first aspect of the invention or part of the determination of the radio communication interference range according to the second aspect of the invention can be.

A detection position (e.g. the first detection position) is the position at which a radio signal parameter (e.g. the first radio signal parameter) or a change in a radio signal parameter (e.g. the first change in the radio signal parameter) was detected. This should be understood, for example, in such a way that the detection of the radio signal parameter or the change in the radio signal parameter is carried out at least partially based on a radio signal received at the detection position (e.g. through a wireless communication interface, e.g. a wireless communication interface in the form of a radio interface). Such a detection position can be detected, for example, by a position sensor (e.g. a position sensor of a global navigation satellite system for determining position such as GPS (Global Positioning System) or Galileo), a radio communication device (e.g. the radio communication device according to the first aspect of the invention) or a commercial vehicle. It goes without saying that the detected detection position can differ slightly from the actual detection position. It goes without saying that embodiments in which the detected detection position deviates slightly from the actual detection position should also be understood as being detected by the invention. Reasons for a slight deviation can be, for example, inaccuracies in determining the position (e.g. within the scope of the typical inaccuracy of a global navigation satellite system for determining position, e.g. an inaccuracy and / or deviation of no more than 5 m, 15 m or 50 m) and / or a time offset (e.g. a time offset of no more than 1 s, 5 s or 10 s) between the detection of the radio signal parameter (e.g. the first radio signal parameter) and / or the change in a radio signal parameter (e.g. the first change in the radio signal parameter) and the detection of the detection position ( e.g. the first detection position).

The first detection position detected according to the first aspect of the invention is, for example, the position at which the radio communication device and / or the utility vehicle was when the radio communication device of the utility vehicle detected the first radio signal parameter or the first change in the radio signal parameter. Likewise, the first detection position according to the second aspect of the invention, when the first radio communication device has detected the first radio signal parameter or the first change, can be the position at which the first radio communication device and / or the first utility vehicle are located has detected the first radio signal parameter or the first change in the radio signal parameter as the first radio communication device of the first utility vehicle.

The first radio interference signal detection information sent to a remote device according to the first aspect of the invention corresponds, for example, to the first radio interference signal detection information received according to the second aspect of the invention from a first radio communication device of a first utility vehicle. The sending and receiving of radio interference signal detection information (e.g. the first radio interference signal detection information) according to the aspects of the invention can for example take place via a communication path which comprises at least one wireless section. It goes without saying that the communication path can comprise further wireless and / or wired sections. An example of a communication path or a section of a communication path is a connection in a communication network such as a wireless communication network (e.g. a cellular network, a WLAN network, a LoRa network or a Bluetooth network) or a wired communication network (e.g. an Ethernet network or a public telephone network).

According to the aspects of the invention, radio interference signal detection information (e.g. the first radio interference signal detection information) can include a radio signal parameter (e.g. the first radio signal parameter) and / or a change in a radio signal parameter (e.g. the first change in the radio signal parameter), for example qualitatively (e.g. in the form of an indication, whether it was determined at least partially based on the radio signal parameter and / or the change in a radio signal parameter that the reception of the radio signal at the respective detection position is impaired (e.g. made difficult or prevented) by a radio interference signal or represented quantitatively (e.g. in the form of a parameter value specification).

Furthermore, radio interference signal detection information (e.g. the first radio interference signal detection information) according to the aspects of the invention can represent a detection position (e.g. the first detection position) in the form of a position specification (e.g. in the form of geographical coordinates such as geographical latitude and longitude).

The determination of the radio communication interference range at least partially based on the first radio interference signal detection information according to the second aspect of the invention takes place, for example, according to predetermined rules.

The fact that the determination is at least partially based on the first radio interference signal detection information is to be understood, for example, in such a way that the first radio interference signal detection information or the information represented by the first radio interference signal detection information is fully or partially taken into account in the determination. For example, when determining the first radio signal parameters represented by the radio interference signal detection information and / or the first changes and / or the first detection information are taken into account.

For example, as disclosed above, determining the radio communications interference area may include determining whether reception of the radio signal at the first detection position is impaired (e.g., difficult) by a radio interference signal. Alternatively, the first radio interference signal detection information, as disclosed above, the first radio signal parameter and / or the first change in the radio signal parameter qualitatively in the form of an indication of whether it was determined that the reception of the radio signal at the first detection position is impaired (e.g. made more difficult) by a radio interference signal. will represent. As disclosed above, this determination can take place according to predetermined rules and / or at least partially on the first radio signal parameter represented by the first radio interference signal detection information and / or the first change in the radio signal parameter represented by the first radio interference signal detection information.

If it has been determined that the reception of the radio signal at the first detection position is impaired (e.g. made more difficult) by a radio interference signal, the radio communication interference area is determined, for example, in such a way that it includes a possible coverage area of the jammer that emitted the radio interference signal and / or an area in which it is expected that no radio communication is possible due to the radio interference signal. This determination can also take place in accordance with predetermined rules and / or or at least partially on the first radio signal parameter represented by the first radio interference signal detection information and / or the first change in the radio signal parameter represented by the first radio interference signal detection information.

For example, it can be assumed that the radio communication is still possible at the first detection position since the first radio interference signal detection information was received according to the second aspect of the invention. Accordingly, it can be specified, for example, that the radio communication interference area is determined in such a way that the first detection position is outside the radio communication interference area and / or on the edge (e.g. a corner or on an edge) of the radio communication interference area.

Alternatively or additionally, it can be assumed that the coverage area of the jammer that emitted the radio interference signal is located in an area in the vicinity of the first detection position (e.g. in a circular area with a predetermined or one of the first radio signal parameter or the first change in the radio signal parameter dependent radius around the first detection position). Accordingly, it can be specified, for example, that the radio communication interference area corresponds to this area and / or is located in this area.

The invention thus takes advantage of the fact that radio signal parameters characteristic of a radio interference signal are also changed by the radio interference signal outside the coverage area of an interfering transmitter, so that the radio interference signal and / or the interfering transmitter can be recognized and that suitable measures (e.g. the alarm actions disclosed below) are then taken in order to minimize the risk to commercial vehicles affected by the radio interference signal and / or the jammer (e.g. commercial vehicles that are within the radio communication interference range). The aspects of the invention thus serve, for example, to identify a radio interference signal and / or an interfering transmitter.

The presence of such a radio interference signal can, for example, lead to a lower signal-to-noise ratio, a lower signal-to-interference ratio, a higher reception field strength, the presence of non-synchronizable carrier frequencies, a higher bit error rate and / or a higher connection termination rate compared to the absence of such a radio interference signal. Accordingly, a radio signal parameter that represents one of these variables and / or properties can be understood as characteristic of whether the reception of the radio signal at the detection position at which the radio signal parameter was detected is impaired (e.g. made more difficult or prevented) by a radio interference signal.

The determination can take place, for example, on the basis of predetermined threshold values. For example, it can be determined that the reception of the radio signal at the detection position (e.g. the first detection position) at which the radio signal parameter (e.g. the first radio signal parameter) was detected is impaired (e.g. difficult) by a radio interference signal and / or that the radio signal parameter thereon indicates if the one (s) represented by this radio signal parameter:

For the reasons disclosed above, the occurrence of a radio interference signal can lead to such changes in the signal-to-noise ratio, the signal-to-interference ratio, the received field strength, the bit error rate, the connection termination rate and the addition of non-synchronizable carrier frequencies. In other words, such a change in a radio signal parameter can also make it possible to determine whether the reception of the radio signal at the detection position at which the change in the radio signal parameter was detected is impaired (eg made more difficult or prevented) by a radio interference signal. In this case, the determination can take place, for example, on the basis of predetermined difference threshold values. For example, it can be determined that the reception of the radio signal at the detection position (e.g. the first detection position) at which the change in the radio signal parameter (e.g. the first change in the radio signal parameter) was detected is impaired (e.g. made more difficult) by a radio interference signal and / or that the change in the radio signal parameter indicates that the change in that radio signal parameter:

• a reduction in the signal-to-noise ratio by more than a predetermined signal-to-noise ratio difference threshold value (e.g. within a predetermined period of time or between two successively detected radio signal parameters),
• a reduction in the signal-to-interference distance by more than a predefined signal-to-interference distance difference threshold value (e.g. within a predefined period of time or between two successively detected radio signal parameters),

• an addition of a number of non-synchronizable carrier frequencies that is greater than a specified threshold value for the number of non-synchronizable carrier frequencies, - an increase in a bit error rate by more than a specified bit error rate difference threshold value (e.g. within a specified time period or between two successively detected radio signal parameters ) is
• an increase in a connection termination rate by more than a predetermined connection termination rate difference threshold value (for example within a predetermined time period or between two successively detected radio signal parameters).

In exemplary embodiments according to the aspects of the invention, the first radio interference signal detection information represents in addition to the at least one first radio signal parameter and / or in addition to the at least one first change in the radio signal parameter at least one further first radio signal parameter and / or at least one further first change in a further radio signal parameter, the further first radio signal parameters and / or the further first change in the further radio signal parameter are characteristic of the radio interference signal. For example, the at least one further radio signal parameter and / or the at least one further change in the further radio signal parameter was detected at the first detection position (and e.g. at the first detection time)

In other words, this should be understood in such a way that the first radio interference signal detection information according to this embodiment represents a plurality of first radio signal parameters and / or a plurality of first changes of a respective radio signal parameter, each of the first radio signal parameters and / or each of the first changes being a respective radio signal parameters are characteristic of the radio interference signal. For example, each of the plurality of first radio signal parameters and / or each of the plurality of first changes in a respective radio signal parameter was detected at the first detection position (and, for example, at the first detection time).

Each of the several first radio signal parameters represents, for example, a different size and / or property of the radio signal such as a signal-to-noise ratio, a signal-to-interference ratio, a reception field strength, the presence of non-synchronizable carrier frequencies, a bit error rate or a connection termination rate. Equally, each of the multiple first changes in a respective radio signal parameter can represent a respective change in a different variable and / or property of the radio signal.

Accordingly, the detection according to the first aspect of the invention can comprise the detection of the plurality of first radio signal parameters and / or the plurality of first changes in a respective radio signal parameter. For example, the detection takes place for each of the multiple first radio signal parameters and / or for each of the multiple first changes of a respective radio signal parameter as disclosed above for the at least one radio signal parameter and / or the at least one change in the radio signal parameter.

The determination of the radio communication interference range according to the second aspect of the invention is based at least partially on the first radio interference signal detection information, which according to this embodiment represents the multiple first radio signal parameters and / or the multiple first changes of a respective radio signal parameter.

For example, as disclosed above, determining the radio communication interference range may include determining whether reception of the radio signal at the first detection position is impaired (eg made more difficult) by a radio interference signal. This determination can be made in accordance with predetermined rules and / or at least partially on the multiple first radio signal parameters represented by the first radio interference signal detection information according to this embodiment and / or by the first radio interference signal detection information according to this embodiment, a plurality of first changes of a respective radio signal parameter take place.

In exemplary embodiments in accordance with aspects of the invention, the radio interference signal is transmitted in a frequency range used by one of the following radio communication networks:

• a WiFi network,
• a Zigbee network,
• a bluetooth network
• a cellular network,
• a LoRa network.

The data transmission via such a radio communication network can accordingly take place in accordance with one of the following communication standards: WLAN communication standard, Zigbee communication standard, Bluetooth communication standard, cellular communication status or LoRa communication standard. The Bluetooth communication standards are currently available on the Internet at www.bluetooth.org. WLAN is specified, for example, in the standards of the IEEE 802.11 family. The specifications of the Zigbee communication standard are currently available on the Internet at https://zigbee.org/. A Mobile radio communication standard is, for example, a 2G / 3G / 4G / 5G communication standard. The specifications of the 2G / 3G / 4G / 5G communication standards are maintained and developed by the 3rd Generation Partnership Project (3GPP) and are currently available on the Internet at www.3gpp.com. The specifications of the LoRa communication standard are currently available on the Internet at https://lora-alliance.org/.

The frequency ranges used by the respective radio communication network are also specified in these communication standards. Further restrictions on these frequency ranges can result, for example, from international agreements and national and regional regulations.

By transmitting the radio interference signal in a frequency range used by one of the radio communication networks mentioned above, the. Reception of a radio signal in the corresponding radio communication network within the coverage area of the jammer transmitting the radio interference signal can be prevented.

It goes without saying that several radio interference signals can be transmitted in a frequency range used by one of the above-mentioned radio communication networks or in different frequency ranges used by the above-mentioned radio communication networks.

In exemplary embodiments according to the aspects of the invention, the first detection position is a commercial vehicle position. For example, the first detection position is a position of the utility vehicle, part of which is the radio communication device according to the first aspect of the invention. According to the second aspect of the invention, the first detection position is a position of the first utility vehicle, part of which is the first radio communication device.

In exemplary embodiments according to the aspects of the invention, the first radio interference signal detection information also represents a first detection speed and / or a first detection movement direction and / or a first detection time.

A detection time (e.g. the first detection time) is the time at which a radio signal parameter (e.g. the first radio signal parameter) or a change in a radio signal parameter (e.g. the first change in the radio signal parameter) was detected. This should be understood, for example, in such a way that the detection of the radio signal parameter or the change in the radio signal parameter takes place at least partially based on a radio signal received at the time of detection (e.g. through a wireless communication interface, e.g. a wireless communication interface in the form of a radio interface).

A detection speed (e.g. the first detection speed) is in the present case, for example, the speed at which a device (e.g. the radio communication device according to the first aspect of the invention) moved when it moved a radio signal parameter (e.g. the first radio signal parameter) or a change in a radio signal parameter (e.g. the first change of the radio signal parameter).

In the present case, a detection movement direction (e.g. the first detection movement direction) is, for example, the direction in which a device (e.g. the radio communication device according to the first aspect of the invention) has moved when a radio signal parameter (e.g. the first radio signal parameter) or a change in a radio signal parameter (e.g. the first change of the radio signal parameter).

For example, radio interference signal detection information (e.g. the first radio interference signal detection information) can include a detection speed (e.g. the first detection speed) in the form of a speed indication and / or a detection movement direction (e.g. the first detection movement direction) in the form of a direction indication and / or a detection time (e.g. the first detection time) in the form of a time stamp.

• Erfassen der ersten Detektionsgeschwindigkeit und/oder der ersten Detektionsbewegungsrichtung und/oder des ersten Detektionszeitpunkts.

The method according to the first aspect of the invention can further comprise:

• Acquisition of the first detection speed and / or the first detection movement direction and / or the first detection time.

The first detection time can be recorded, for example, by a clock of the radio communication device and / or of the utility vehicle. The first Detection speed can be detected by a speed sensor of the radio communication device and / or the utility vehicle; and the first detection direction is detected, for example, by a movement sensor of the radio communication device and / or of the utility vehicle.

It goes without saying that the recorded first detection speed can differ from the actual first detection speed and / or the recorded first detection movement direction from the actual first detection movement direction and / or the recorded first detection time can differ from the actual first detection time (e.g. slightly). It goes without saying that embodiments in which such (e.g. minor) deviations exist should also be understood as being covered by the invention. Reasons for a slight deviation can be, for example, inaccuracies in the detection of the first detection speed and / or the first detection movement direction and / or the first detection time (e.g. measurement inaccuracies) and / or a time offset (e.g. a time offset of no more than 1 s, 5 s or 10 s) between the detection of the first radio signal parameter and / or the first change in the radio signal parameter and the acquisition of the first detection speed and / or the first detection movement direction and / or the first detection time.

The first radio interference signal detection information can represent, for example, the recorded first detection speed and / or the recorded first detection movement direction and / or the recorded first detection time.

• Empfangen und/oder Bereithalten einer Vielzahl von Nutzfahrzeugpositionsinformationen, wobei jede der Vielzahl von Nutzfahrzeugpositionsinformationen eine vergangene oder aktuelle Position eines jeweiligen Nutzfahrzeugs einer Vielzahl von Nutzfahrzeugen repräsentiert,
• Bestimmen zumindest teilweise basierend auf der Vielzahl von Nutzfahrzeugpositionsinformationen, ob sich zumindest ein Nutzfahrzeug der Vielzahl von Nutzfahrzeugen innerhalb des Funkkommunikationsstörbereichs befand oder befindet oder befinden wird,
• Auslösen oder Bewirken des Auslösens einer Alarmaktion, wenn bestimmt wird, dass sich zumindest ein Nutzfahrzeug der Vielzahl von Nutzfahrzeugen innerhalb des Funkkommunikationsstörbereichs befand oder befindet oder befinden wird.

In exemplary embodiments according to the second aspect, the method further comprises at least one of the following steps:

• Receiving and / or holding a large number of commercial vehicle position information items, each of the large number of commercial vehicle position information items representing a past or current position of a respective commercial vehicle of a large number of commercial vehicles,
• Determining, based at least in part on the plurality of commercial vehicle position information items, whether there is at least one commercial vehicle of the plurality of commercial vehicles was or is or will be located within the radio communication interference area,
• Triggering or causing an alarm action to be triggered when it is determined that at least one commercial vehicle of the plurality of commercial vehicles was or is or will be located within the radio communication interference area.

As disclosed above, according to aspects of the invention, a detection position may be a utility vehicle position. Accordingly, each of the plurality of utility vehicle position information can be part of radio interference signal detection information received according to the second aspect of the invention (for example the first radio interference signal detection information disclosed above, which represents the first detection position, and / or the second radio interference signal detection information disclosed below, which the second detection position represented). Alternatively or additionally, the commercial vehicle position information of the plurality of commercial vehicle position information can be received at least partially separately from such radio interference signal detection information.

The fact that each of the plurality of utility vehicle position information represents a past or current position of a respective utility vehicle of the plurality of utility vehicles should be understood, for example, such that the plurality of utility vehicle position information for each of the utility vehicles contains at least one utility vehicle position information received for the respective utility vehicle. The current position of a respective utility vehicle is represented, for example, by the last utility vehicle position information received for the respective utility vehicle, and a past position of a respective utility vehicle is represented, for example, by each utility vehicle position information received before the last utility vehicle position information received for the respective utility vehicle. It goes without saying that the large number of commercial vehicle position information items can be limited to representations of current positions of the large number of commercial vehicles, so that each of the large number of commercial vehicle positions represents a current position of a respective commercial vehicle of the large number of commercial vehicles.

For example, each of the utility vehicles of the multiplicity of utility vehicles can record its respective position continuously or repeatedly (for example at regular time intervals) and send corresponding utility vehicle position information to the device (s) that carries out the method according to the second aspect of the invention. Such a position of a commercial vehicle can be detected, for example, by a position sensor (e.g. a position sensor of a global navigation satellite system for determining position such as GPS (Global Positioning System) or Galileo) of the commercial vehicle or a radio communication device of the commercial vehicle (e.g. the radio communication device according to the first aspect of the invention).

The sending and receiving of commercial vehicle position information according to the aspects of the invention can, as disclosed above for the radio interference signal detection information, take place, for example, via a communication path which comprises at least one wireless section. It goes without saying that the communication path can comprise further wireless and / or wired sections. An example of a communication path or a section of a communication path is a connection in a communication network such as a wireless communication network (e.g. a cellular network, a WLAN network, a LoRa network or a Bluetooth network) or a wired communication network (e.g. an Ethernet network or a public telephone network).

Commercial vehicle position information can be kept ready, for example, by being stored in a memory of a device (e.g. the device according to the second aspect of the invention). For example, each commercial vehicle position information received according to the second aspect of the invention is stored (e.g. at least until more current commercial vehicle position information is received for the respective commercial vehicle).

• Bestimmen, ob sich ob sich zumindest ein Nutzfahrzeug der Vielzahl von Nutzfahrzeugen innerhalb des Funkkommunikationsstörbereichs befand, zumindest teilweise basierend auf einer durch die Vielzahl von Nutzfahrzeugpositionsinformationen repräsentierten vergangenen Positionen des Nutzfahrzeugs der Vielzahl von Nutzfahrzeugen,

The determination of whether at least one commercial vehicle of the plurality of commercial vehicles was or is or will be located within the radio communication interference area should include at least one of the following steps:

• Determining whether at least one utility vehicle of the plurality of utility vehicles was within the radio communication interference area, based at least in part on a past positions of the utility vehicle of the plurality of utility vehicles represented by the plurality of utility vehicle position information,
• Determining whether at least one utility vehicle of the plurality of utility vehicles is located within the radio communication interference area, at least partially based on a current position of the utility vehicle of the plurality of utility vehicles represented by the plurality of utility vehicle position information,
• Determining whether at least one utility vehicle of the plurality of utility vehicles is located within the radio communication interference area is based at least in part on a current position of the utility vehicle of the plurality of utility vehicles represented by the plurality of utility vehicle position information.

The fact that the determination of whether at least one utility vehicle of the plurality of utility vehicles was or is or will be located within the radio communication interference area is at least partially based on the plurality of utility vehicle position information is to be understood accordingly, for example, in such a way that at least a part (e.g. each) of the by the plurality past and / or current positions represented by commercial vehicle position information is taken into account in the determination.

For example, when determining whether at least one utility vehicle of the plurality of utility vehicles is or will be located within the radio communication interference area, only the current positions represented by the plurality of utility vehicle position information can be taken into account; and when determining whether at least one utility vehicle of the plurality of utility vehicles was within the radio communication interference area, for example only the past positions represented by the plurality of utility vehicle position information are taken into account.

Furthermore, the determination of whether at least one commercial vehicle of the plurality of commercial vehicles was or is or will be located within the radio communication interference area can take place in accordance with predefined rules. For example, it can be specified that it is determined that a utility vehicle of the plurality of utility vehicles is located within the radio communication interference area if a respective utility vehicle position information item of the plurality of utility vehicle position information items is a position within the current position of this utility vehicle Radio communication interference area represents. Alternatively or additionally, it can be specified that it is determined that a utility vehicle of the plurality of utility vehicles will be located within the radio communication interference area if a respective utility vehicle position information item of the plurality of utility vehicle position information is a position at a distance from the edge of the radio communication interference area that is less than the current position of this utility vehicle is represented as a predetermined distance threshold value (for example 5 m or 10 m or 50 m). Furthermore, it can alternatively or additionally be specified that it is determined that a utility vehicle of the plurality of utility vehicles was located within the radio communication interference area if a respective utility vehicle position information item of the plurality of utility vehicle position information represents a position within the radio communication interference area as the past position of this utility vehicle.

If it is determined that at least one commercial vehicle of the plurality of commercial vehicles was or is or will be located within the radio communication interference area, it is assumed, for example, that this commercial vehicle was or is or will be in the coverage area of a jammer and thus an increased risk of theft existed or exists or will exist (ie the commercial vehicle was / is endangered). Because such jammers are often used in the event of theft to prevent radio communication from the commercial vehicle (e.g. with an emergency call point).

It can therefore be provided that if it is determined that at least one commercial vehicle of the plurality of commercial vehicles was or is or is located within the radio communication interference area, an alarm action is carried out or an alarm action is carried out. By causing an alarm action to be carried out is to be understood as meaning that the device (s) that carry out the method according to the second aspect of the invention do not carry out the alarm action, but rather cause another apparatus (e.g. a commercial vehicle ) executes the alarm action.

An alarm action can notify a user such as an emergency call center or one or more drivers of commercial vehicles who are in the vicinity of the endangered commercial vehicle (eg within an area with a predetermined radius around the current one Position of the endangered commercial vehicle) or a dispatcher responsible for the endangered commercial vehicle. The emergency call point or the dispatcher responsible for the endangered commercial vehicle can be assigned to the endangered commercial vehicle (e.g. in an entry in a database) and notified by telephone by an automatic call (e.g. to a telephone number stored in the entry in the database). The utility vehicles that are in the vicinity of the endangered utility vehicle (for example within an area with a predetermined radius around the current position of the endangered utility vehicle) can be determined, for example, at least partially based on the plurality of utility vehicle position information. The drivers of the commercial vehicles for whom it has been determined that they are in the vicinity of the endangered commercial vehicle (e.g. within an area with a predetermined radius around the current position of the endangered commercial vehicle) can then be called by an automatic call (e.g. to an in an entry in a database for the respective commercial vehicle stored telephone number).

Alternatively or additionally, an alarm action can be an action carried out by one or more commercial vehicles that are in the vicinity of the commercial vehicle at risk (e.g. within an area with a predetermined radius around the current position of the commercial vehicle at risk), such as activating the hazard warning lights and / or the low or high beam and / or a horn of the respective commercial vehicle. As disclosed above, the utility vehicles that are in the vicinity of the endangered utility vehicle (e.g. within an area with a predetermined radius around the current position of the endangered utility vehicle) can for example be determined based at least in part on the plurality of utility vehicle position information. Control information can then be sent to the commercial vehicles for which it has been determined that you are in the vicinity of the commercial vehicle at risk (e.g. within an area with a predetermined radius around the current position of the commercial vehicle at risk) that are set up, the commercial vehicles controlled in such a way that they carry out the respective action such as activating the hazard warning lights and / or the dipped or high beam and / or a horn.

Alternatively or additionally, the method according to the second aspect can comprise the following step:

• Requesting a second radio interference signal detection information from a second radio communication device of a second commercial vehicle, wherein the plurality of commercial vehicle position information represents a current position of the second commercial vehicle; which is within a specified distance (e.g. 50 m, 100 m 500 m, 1000 m or 5000 m) from the first detection position.

If it is determined based at least in part on the first radio interference signal detection information that the reception of the radio signal at the first detection position is impaired (e.g. made more difficult) by a radio interference signal, provision can be made, for example, for radio interference signal detection information to be requested from the second radio communication device of the second commercial vehicle is when the second commercial vehicle is within the specified distance (for example 50 m, 100 m, 500 m, 1000 m or 5000 m) from the first detection position. For this purpose, for example, it can be determined based at least in part on the large number of commercial vehicle position information that the second commercial vehicle is located within the predetermined distance (e.g. 50 m, 100 m, 500 m, 1000 m or 5000 m) from the first detection position.

In exemplary embodiments according to the second aspect of the invention, the radio communication interference range is determined in such a way that it represents an area in which, based at least in part on the first radio interference signal detection information, it is expected that no radio communication is possible due to the radio interference signal. As disclosed above, the determination can take place in accordance with predetermined rules.

In exemplary embodiments according to the second aspect of the invention, the method further comprises:

• Receiving a second radio interference signal detection information from a second radio communication device of a second commercial vehicle, the second radio interference signal detection information both at least one (e.g. detected by the second radio communication device) second radio signal parameter and / or at least one (e.g. detected by the second radio communication device) second change in a radio signal parameter as well as a second detection position, wherein the (eg detected by the second radio communication device) second radio signal parameter (ie the at least one second radio signal parameter) and / or the (eg by the second Radio communication device detected) second change in the radio signal parameter (ie the at least one second change in the radio signal parameter) is characteristic of a radio interference signal, and wherein the (e.g. detected by the second radio communication device) second radio signal parameter (ie the at least one second radio signal parameter) and / or the (by the second radio communication device detected) the second change in the radio signal parameter (ie the at least one second change in the radio signal parameter) was detected at the second detection position.

It goes without saying that the second radio communication device, like the first radio communication device according to the second aspect of the invention, can be a radio communication device according to the first aspect of the invention.

Furthermore, it goes without saying that the second radio communication device of the second commercial vehicle can be at least partially different from the first radio communication device of the first commercial vehicle. For example, the second radio signal parameter and / or the second change in the radio signal parameter can be different from the first radio signal parameter and / or the first change in the radio signal parameter according to the second aspect of the invention. Alternatively or additionally, the second detection position can be different from the first detection position according to the second aspect of the invention.

In addition, the above disclosure with regard to the first radio interference signal detection information according to the second aspect of the invention is also intended to apply as a disclosure for the second radio interference signal detection information according to the second aspect of the invention.

In particular, the radio communication interference range should also be determined at least partially based on the second radio interference signal detection information. In other words, the second radio interference signal detection information should be taken into account in the same way as the first radio interference signal detection information when determining the radio communication interference range. As disclosed above, the radio communication interference range can be determined in accordance with predetermined rules. These rules should apply equally to the first radio interference signal detection information and the second radio interference signal detection information, for example.

As disclosed above, it can be specified, for example, that the radio communication interference area is determined in such a way that the first detection position is outside the radio communication interference area and / or on the edge (e.g. a corner or on an edge) of the radio communication interference area. Accordingly, the radio communication interference area should be determined with additional consideration of the second radio interference signal detection information in such a way that the first detection position and the second detection position are outside the radio communication interference area and / or on the edge (e.g. a respective corner or on a respective edge) of the radio communication interference area.

Alternatively or additionally, it can be assumed that the coverage area of the jammer that emitted the radio interference signal is located both in an area in the vicinity of the first detection position and in an area in the vicinity of the second detection position (e.g. in a circular area with a predetermined radius around the first detection position or a radius that is dependent on the first radio signal parameter or the first change in the radio signal parameter). Accordingly, it can be specified, for example, that the radio communication interference area corresponds to an area and / or is located in an area in which the area in the vicinity of the first detection position and the area in the vicinity of the second detection position overlap. For example, the radio communication interference area corresponds to and / or is located in the overlap area in which a first circular area with a predetermined radius or a radius that is dependent on the first radio signal parameter or the first change in the radio signal parameter is located around the first detection position and a second circular area with a predetermined one or intersect a radius around the second detection position that is dependent on the second radio signal parameter or the second change in the radio signal parameter.

For this purpose, for example, based on the above disclosed received and / or kept available large number of commercial vehicle position information, it can be determined whether one or more other commercial vehicles are within the specified distance (e.g. 50 m, 100 m 500 m, 1000 m or 5000 m) from the first detection position. The second utility vehicle is obtained, for example, as a result of this determination. For example, it is determined that the second commercial vehicle is located within the predetermined distance from the first detection position if commercial vehicle position information from the plurality of commercial vehicle position information represents a current commercial vehicle position of the second commercial vehicle within the predetermined distance from the first detection position.

The system 1 includes, inter alia, a first utility vehicle 101 Fig. 1a a second commercial vehicle 102 and further commercial vehicles 103 to 105 are shown as part of the system 1, so that the system 1 has a plurality of commercial vehicles 101 to 105. The commercial vehicles 102 to 105 should only be understood as optional parts of the system 1. Commercial vehicles 101 to 105 are in Fig. 1a Shown by way of example as semi-trailers that are pulled by one of the respective towing vehicles 106 to 110. Each of the semi-trailers 101 to 105 includes one of the radio communication devices 2-1 to 2-5, each of them Radio communication apparatus is a radio communication apparatus according to the first aspect of the invention.

The system 1 further comprises a device 3 which is remote from the semi-trailers 101 to 105 and the radio communication devices 2-1 to 2-5, which is shown in FIG Fig. 1a is shown as an example as a server. Server 3 is a device according to the second aspect of the invention.

In Fig. 1a respective communication paths 111 to 115 between the radio communication devices 2-1 to 2-5 of the semi-trailers 101 to 105 and the server 3 are shown. Via the communication path 111, the radio communication device 2-1 of the semi-trailer 101 and the server 3 can exchange information (eg radio interference signal detection information) (eg send and receive). In the same way, the radio communication devices 2-2 to 2-5 of the semi-trailers 102 to 105 and the server 3 can exchange information (for example, send and receive) information (eg radio interference signal detection information) via the respective communication paths 112 to 115.

In the following, it is assumed by way of example that each of the communication paths 111 to 115 comprises a respective connection via a cellular network such as a 2G / 3G / 4G / 5G communication network. For example, the radio communication devices 2-1 to 2-5 can wirelessly transmit and / or receive information about the respective connection via the cellular network of the respective communication path of the communication paths 111 to 115. As disclosed above, the specifications of the 2G / 3G / 4G / 5G communication standards are maintained and developed by the 3rd Generation Partnership Project (3GPP) and are currently available on the Internet, inter alia, at www.3gpp.com.

It should be understood that each of the communication paths 111-115 may further include a connection over a wired network such as an Ethernet network. For example, it is assumed in the following that the server 3 sends information about the respective connection via the wired network of the respective communication path of the communication paths 111 to 115 in a wired manner and / or can receive. Ethernet is specified, for example, in the standards of the IEEE 802.3 family.

The exchange of information via the communication paths 111 to 115 can take place in encrypted form.

In addition, in Fig. 1a a dispatcher and / or an emergency call point optionally shown with the reference number 124. The server 3 can communicate with the dispatcher / emergency call point 124, for example via the communication path 125. Dispatcher / emergency number 124 should not be understood as part of system 1.

Figure 1b is a schematic representation of an exemplary scenario for explaining the invention. Figure 1b FIG. 10 shows a plan view of an arrangement of the semi-trailers 101 to 105 of FIG Fig. 1a system shown, for example, the semi-trailers are parked according to this arrangement in a parking lot.

A jammer 116 is also located between the semi-trailers 104 and 105.

This jamming transmitter 116 is set up, for example, to transmit a radio interference signal in order to prevent the reception of a mobile radio signal. For this purpose, the radio interference signal is transmitted, for example, by the jamming transmitter with the same frequency as the carrier signal of the mobile radio signal or with a frequency in the same frequency band as the carrier signal of the mobile radio signal, so that the radio interference signal is superimposed on the mobile radio signal within a coverage area 117 of the jamming transmitter in such a way that the reception of the mobile radio signal is prevented. For example, this superposition leads to such a reduction in the signal-to-noise ratio within the coverage area 117 of the jammer 116 that the reception of the mobile radio signal is not possible; and in the vicinity of the jammer, but outside the coverage area 117 of the jammer (e.g. in an area bordering the edge of the coverage area), the reception of the mobile radio signal may be possible, but difficult (e.g. due to a reduced signal-to-noise ratio there as well) . At the same time as the reduction in the signal-to-noise ratio, for example, there is an increased reception field strength. It goes without saying that the jammer 116 can transmit a plurality of radio interference signals (for example simultaneously and / or on different frequencies and / or in different frequency bands). The semi-trailers 104 and 105 are located within the coverage area 117 of the jammer 116, and the semi-trailers 101, 102 and 103 are located outside the coverage area 117 of the jammer 116. In the following, it is therefore assumed that the semi-trailers 104 and 105 do not receive a mobile radio signal and therefore do not can exchange information with the server 3 via the respective communication paths 114 and 115. Furthermore, it is assumed in the following that the reception of the mobile radio signal by the respective radio communication device of the semi-trailers 101, 102 and 103 is made more difficult due to the reduced signal-to-noise ratio, but that this continues to provide information to the server via the respective communication paths 111, 112 and 113 3 can exchange.

Fig. 2 shows a schematic representation of an embodiment of a radio communication device 2 according to the first aspect of the invention. In the following, it is assumed by way of example that each of the radio communication devices 2-1 to 2-5 of the semitrailers 101 to 105 of the in Fig. 1 illustrated system 1 of this in Fig. 2 radio communication device 2 shown corresponds.

The radio communication device 2 comprises a processor 200 and, connected to the processor 200, has a first memory as program memory 201, a second memory as main memory 202 and a first network interface 203 and a position sensor 204. Furthermore, the radio communication device 2 optionally includes a second network interface 205.

A processor should be understood to mean, for example, a microprocessor, a microcontroller, a microcontroller, a digital signal processor (DSP), an application-specific integrated circuit (ASIC) or a field programmable gate array (FPGA). It goes without saying that the radio communication device 2 can also comprise a plurality of processors 200.

Processor 200 executes program instructions that are stored in program memory 201 and stores, for example, intermediate results or the like in main memory 202. Program memory 201 contains, for example, program instructions of a computer program according to the first aspect of the invention, the program instructions which cause the processor 200 to execute the method according to the first aspect of the invention (for example the method according to the in Fig. 4 to execute and / or control when the processor 200 executes these program instructions stored in program memory 201.

Program memory 201 also contains, for example, the operating system of radio communication device 2, which is at least partially loaded into main memory 202 and executed by processor 200 when radio communication device 2 is started. In particular, when the radio communication device 2 is started, at least part of the kernel of the operating system is loaded into the main memory 202 and executed by the processor 200.

An example of an operating system is a Windows, UNIX, Linux, Android, Apple iOS and / or MAC OS operating system. In particular, the operating system enables the radio communication device 2 to be used for data processing. For example, it manages resources such as a main memory and a program memory, provides other computer programs with basic functions through programming interfaces, and controls the execution of computer programs.

A program memory is, for example, a non-volatile memory such as a flash memory, a magnetic memory, an EEPROM memory (electrically erasable programmable read-only memory) and / or an optical memory. A main memory is, for example, a volatile or non-volatile memory, in particular a memory with random access (RAM) such as a static RAM memory (SRAM), a dynamic RAM memory (DRAM), a ferroelectric RAM memory (FeRAM) and / or a magnetic RAM memory (MRAM).

Main memory 202 and program memory 201 can also be designed as one memory. Alternatively, main memory 202 and / or program memory 201 can each be formed by a plurality of memories. Furthermore, main memory 202 and / or program memory 201 can also be part of processor 200.

Processor 200 controls the first network interface 203. Network interface 203 is a wireless network interface in the form of a radio interface. The following is It is assumed by way of example that the network interface 203 is set up to exchange information with a remote device (eg to send and / or receive) via a connection in a cellular network such as a 2G / 3G / 4G / 5G communication network. The communication interface 203 is thus a cellular network interface (for example a 2G / 3G / 4G / 5G communication interface).

Furthermore, network interface 203 is set up to detect (e.g. measure and / or determine) one or more radio signal parameters at regular time intervals (e.g. at regular time intervals of 2 s, 60 s, 5 min or 15 min). Such a radio signal parameter represents, for example, a size and / or property of a mobile radio signal received through the network interface 203. In the following, it is assumed by way of example that the network interface 203 is set up to detect a radio signal parameter that represents a signal-to-noise ratio of a mobile radio signal received through the network interface 203, and to detect a further radio signal parameter that is a received field strength of the through the network interface 203 received mobile radio signal.

For example, the radio communication device 2 can use the first network interface 203 to communicate information (eg radio interference signal detection information) via one of the communication paths 111 to 115 with the server 3 of the in FIG Fig. 1 to exchange illustrated system 1 (for example to send and / or receive) and to detect a radio signal parameter which represents a signal-to-noise ratio of a mobile radio signal received through the network interface 203. For this purpose, the communication interface 203 comprises, for example, an antenna and a transmitter circuit and a receiver circuit or a transceiver circuit.

Furthermore, processor 200 controls position sensor 204, which is set up to detect a position of radio communication device 2. An example of such a position sensor is a position sensor of a global navigation satellite system for determining position such as GPS (Global Positioning System) or Galileo.

In addition, processor 200 controls the optional second network interface 205, which is designed, for example, as a wired network interface in the form of a CAN, K-line, LIN or Flexray interface. It is set up for example wired communication with one or more commercial vehicle sensors and / or commercial vehicle components of a commercial vehicle (e.g. the one in Fig. 1 semi-trailers 101 to 105 shown) via one or more wired communication connections of a CAN, K-line, LIN or Flexray bus system of the commercial vehicle. For example, the radio communication device 2 can receive commercial vehicle information (eg speed information and / or directional information) from the commercial vehicle sensors and / or commercial vehicle components through the network interface 205 and / or send control information to the commercial vehicle sensors and / or commercial vehicle components. CAN is specified in the standards of the ISO 11898 family, K-line is specified in the standards ISO 9141 and ISO 14230-1, LIN is specified in the standards of the ISO 17987 family, and FlexRay is specified in the standards of the ISO 17458 family.

The components 200 to 205 of the radio communication device 2 are communicatively and / or operatively connected to one another, for example via one or more bus systems (e.g. one or more serial and / or parallel bus connections).

It goes without saying that the radio communication device 2 can comprise further components (e.g. a user interface) in addition to the components 200 to 205.

Fig. 3 shows a schematic representation of an embodiment of a device 3 according to the first aspect of the invention. In the following, it is assumed as an example that the server 3 of the in Fig. 1 illustrated system 1 of this in Fig. 2 device 3 shown corresponds. To simplify matters, the in Fig. 2 The device 3 shown is therefore also referred to as the server 3.

The server 3 comprises a processor 300 and, connected to the processor 300, has a first memory as program memory 301, a second memory as main memory 302 and a network interface 303.

Processor 300 is designed in particular as a microprocessor, microcontroller such as microcontroller, digital signal processor (DSP), application-specific integrated circuit (ASIC) or field programmable gate array (FPGA).

Processor 300 executes program instructions that are stored in program memory 301 and stores, for example, intermediate results or the like in main memory 302.

In the program memory 301, for example, program instructions are stored that cause the processor 300, when it executes the program instructions, to use the method according to the second aspect of the invention (for example the method according to the in Fig. 5 illustrated flowchart 5) to at least partially execute and / or control.

Processor 300 controls network interface 303, which is set up, for example, to exchange information with a remote device via a connection in a communication network (for example to send and / or receive). In the following, it is assumed by way of example that the network interface 303 is a wired network interface. An example of a wired network interface is an Ethernet interface. Ethernet is specified, for example, in the standards of the IEEE 802.3 family. For example, the radio communication device 2 can use the network interface 303 to communicate information (eg radio interference signal detection information) via one of the communication paths 111 to 115 with one of the radio communication devices 2-1 to 2-5 of FIG Fig. 1 to exchange shown system 1 (e.g. to send and / or receive)

The components 300 to 303 of the server are communicatively and / or operatively connected to one another, for example via one or more bus systems (e.g. one or more serial and / or parallel bus connections).

It will be understood that the server, apart from components 300 to 303, may include other components (e.g., a user interface).

Fig. 4 FIG. 4 shows a flow diagram 4 of an exemplary embodiment of a method according to the first aspect of the invention. In the following, it is assumed by way of example that steps 400 to 402 are carried out by the radio communication device 2-1 of the in Fig. 1a illustrated system 1 in the scenario according to Figure 1b are executed.

In a step 400, at least a first radio signal parameter and / or at least a first change in a radio signal parameter is detected, the first Radio signal parameters and / or the first change in the radio signal parameter is characteristic of a radio interference signal.

A radio signal parameter is, for example, a parameter that qualitatively or quantitatively represents a (e.g. physical) variable and / or property of a radio signal. Such a radio signal parameter or a change in such a radio signal parameter should, for example, be understood as characteristic of a radio interference signal if it is possible to determine on the basis of this whether the reception of a radio signal at the respective detection position (e.g. the first detection position) is impaired by a radio interference signal (e.g. difficult). For example, such radio signal parameters characteristic of a radio interference signal can represent a signal-to-noise ratio, a signal-to-interference ratio, a received field strength, the presence of non-synchronizable carrier frequencies, a bit error rate or a connection termination rate. Changes in a radio signal parameter characteristic of a radio interference signal are, for example, changes between two successively detected radio signal parameters, both of which represent one of these properties and / or quantities of the radio signal.

As disclosed above, the network interface 203 of the radio communication device 2-1 is set up, for example, to measure and / or determine a signal-to-noise ratio and a received field strength of a mobile radio signal received through the network interface 203. In the following, it is therefore assumed that in step 400 a signal-to-noise ratio and a received field strength of a mobile radio signal received through the network interface 203 of the radio communication device 2-1 are measured and / or determined. As a result of step 400, for example, two first radio signal parameters are obtained and stored in program memory 201 of radio communication device 2-1, one of the first radio signal parameters representing the measured and / or determined signal-to-noise ratio (e.g. quantitative, e.g. in the form of a parameter value specification of the measured Signal-to-noise ratio in dB) and the other of the first radio signal parameters represents the measured and / or determined received field strength (for example, quantitative, for example in the form of a parameter value specification of the measured received field strength in dBm).

In the scenario according to Figure 1b the reception of the mobile radio signal through the network interface 203 is made more difficult due to the reduced signal-to-noise ratio. Correspondingly, in step 400, the radio communication device 2-1 detects a reduced signal-to-noise ratio (for example a signal-to-noise ratio of less than 10 dB or 15 dB). At the same time, the radio communication device 2-1 detects in step 400 an increased reception field strength (for example a reception field strength greater than -80 dBm or -70 dBm).

In a step 401, a first detection position is recorded, the first radio signal parameter and / or the first change in the radio signal parameter being detected at the first detection position. For example, the position sensor 204 of the radio communication device 2-1 detects the first detection position in step 401. The first detection position is also to be understood as the commercial vehicle position of the semi-trailer 101, of which the radio communication device 2-1 is part. As a result of step 401, for example, first detection position information representing the detected first detection position is obtained and stored in program memory 201 or main memory 202 of radio communication device 2-1.

In the following, it is assumed that the position sensor 204 the in Figure 1b The position of the radio communication device 2-1 provided with the reference numeral 118 is detected as the first detection position in step 401, the reduced signal-to-noise ratio detected in step 400 and the increased reception field strength detected in step 400 based on one at the first detection position 118 through the network interface 203 received mobile radio signal were detected.

In a step 402, first radio interference signal detection information is sent to a remote device (for example server 3 in Fig. 1a ), the first radio interference signal detection information representing both the first radio signal parameter and / or the first change in the radio signal parameter and the first detection position. The sending in step 402 can for example take place in response (for example as soon as possible or immediately) to the detection in step 400 and the acquisition in step 401.

Since the semi-trailer 101 with the radio communication device 2-1 is outside the coverage area 117 of the jammer 116, the Exchange radio communication device 2-1 of the semi-trailer 101 with the server 3 in spite of the radio interference signal transmitted by the jammer. In the following, it is therefore assumed that the first radio interference signal detection information is sent in step 402 through the network interface 203 via the communication path 111 to the server 3. The first radio interference signal detection information represents the reduced signal-to-noise ratio detected in step 400 and the increased received field strength detected in step 400 as well as the first detection position 118 detected in step 401.

Fig. 5 FIG. 5 shows a flow diagram 5 of an exemplary embodiment of a method according to the second aspect of the invention. In the following, it is assumed by way of example that steps 500 to 504 are carried out by the server 3 of the in Fig. 1a illustrated system 1 in the scenario according to Figure 1b are executed.

In a step 500, at least one piece of first radio interference signal detection information is received from a first radio communication device of a first commercial vehicle. For example, the network interface 303 of the server 3 can transmit the at least one first radio interference signal detection information item in step 500 via one of the communication paths 111 to 115 from one of the semi-trailers 101 to 105 or one of the radio communication devices 2-1 to 2-5, each of which is part of one of the Semi-trailers 101 to 105 are received.

The first radio interference signal detection information represents both at least a first radio signal parameter and / or at least a first change in a radio signal parameter as well as a first detection position, the first radio signal parameter and / or the first change in the radio signal parameter being characteristic of a radio interference signal, and where the radio signal parameter and / or or the change in the radio signal parameter was detected at the first detection position. In particular, the first radio interference signal detection information received in step 500 can correspond to the information received in step 402 of the in Fig. 4 flowchart 4 shown correspond.

It goes without saying that in step 500 the server 3 can receive a plurality of radio interference signal detection information from a plurality of radio communication devices of a plurality of commercial vehicles.

As disclosed above, the semi-trailers 102 and 103 are like the semi-trailer 101 in the scenario according to FIG Figure 1b outside the coverage area 117 of the jammer, so that its radio communication devices 2-2 and 2-3, such as the radio communication device 2-1 of the semi-trailer 101, can exchange information with the server 3 despite the radio interference signal transmitted by the jammer 116. However, the reception of the mobile radio signal at the station with the reference number 121 in FIG Figure 1b provided position of the semi-trailer 102 and at the with the reference number 122 in Figure 1b provided position of the semi-trailer 103 difficult. The radio communication device 2-2 of the semi-trailer 102 detects in the scenario according to FIG Figure 1b at the detection position 121 thus a reduced signal-to-noise ratio and an increased reception field strength, and the radio communication device 2-3 of the semi-trailer 103 detects in the scenario according to FIG Figure 1b at the detection position 122 a reduced signal-to-noise ratio and an increased reception field strength.

In the following it is therefore assumed that in step 500 a first radio interference signal detection information via the communication path 111 from the radio communication device 2-1 of the semi-trailer 101, a second radio interference signal detection information via the communication path 112 from the radio communication device 2-2 of the semi-trailer 102 and a third radio interference signal detection information is received via the communication path 113 from the radio communication device 2-3 of the semi-trailer 103. The first radio interference signal detection information received in step 500 corresponds to that in step 402 of the in Fig. 4 flowchart 4 shown by the radio communication device 2-1 of the semi-trailer 101 and thus represents the reduced signal-to-noise ratio detected in step 400 and the increased reception field strength detected in step 400 as well as the first detection position 118 detected in step 401 the second radio interference signal detection information received in step 500 represents a reduced signal-to-noise ratio detected at the detection position 121 by the radio communication device 2-2 of the semi-trailer 102 and an increased reception field strength detected at the detection position 121 by the radio communication device 2-2 of the semi-trailer 102 as well the second detection position 121; and represents the third radio interference signal detection information received in step 500 a reduced signal-to-noise ratio detected at the detection position 122 by the radio communication device 2-3 of the semitrailer 103 and an increased reception field strength detected at the detection position 122 by the radio communication device 2-3 of the semitrailer 103, as well as the third detection position 123.

In a step 501, a radio communication interference area is determined based at least in part on the first radio interference signal detection information.

For example, the determination in step 501 can include determining whether the reception of the radio signal at the first detection position represented by the first radio interference signal detection information is impaired (e.g., made difficult) by a radio interference signal. This determination can be based on predefined rules which, as disclosed above, can predetermine, for example, a threshold value for the at least one first radio signal parameter represented by the first radio interference signal detection information and / or a difference threshold value for the at least one change represented by the first radio interference signal detection information . The rules can also, for example, stipulate that if this threshold value and / or difference threshold value is exceeded or fallen below, it should be determined that the reception of the radio signal at the first detection position represented by the first radio interference signal detection information is impaired (e.g. more difficult) by a radio interference signal. becomes.

If it has been determined that the reception of the radio signal at the first detection position is impaired (e.g. made more difficult) by a radio interference signal, the radio communication interference area is determined, for example, in such a way that it includes a possible coverage area of the jammer that emitted the radio interference signal and / or an area in which it is expected that no radio communication is possible due to the radio interference signal. This determination can also take place in accordance with predetermined rules and / or or at least partially on the first radio signal parameter represented by the first radio interference signal detection information and / or the first change in the radio signal parameter represented by the first radio interference signal detection information.

• der durch die jeweilige Funkstörsignal-Detektionsinformation repräsentierte Signal-Rausch-Abstand ist geringer als ein vorgegebener Signal-Rausch-Abstandsschwellwert (z.B. 10dB oder 15dB) ist, und
• die durch die jeweilige Funkstörsignal-Detektionsinformation repräsentierte Empfangsfeldstärke ist größer als ein vorgegebener Empfangsfeldstärkeschwellwert (z.B. -80 dBm oder -70dBm).

It goes without saying that for each of the radio interference signal detection information received in step 500, it can first be determined in step 500 whether the reception of the radio signal at the respective detection position represented by the respective radio interference signal detection information is impaired (e.g. made more difficult) by a radio interference signal. Since in this example the radio interference signal detection information received in step 500 represents a signal-to-noise ratio and a received field strength, the rules for this can specify, for example, that the reception of the radio signal at the respective detection position is impaired (e.g. made more difficult) if the following conditions are caused by the respective Radio signal parameters of the respective radio interference signal detection information are met:

• the signal-to-noise ratio represented by the respective radio interference signal detection information is less than a predetermined signal-to-noise ratio threshold value (eg 10dB or 15dB), and
• the received field strength represented by the respective radio interference signal detection information is greater than a predefined received field strength threshold value (eg -80 dBm or -70 dBm).

In the following, it is assumed that these conditions are met for each of the three radio interference signal detection information items received in step 500, so that it is determined that the reception of the radio signal at the detection positions 118, 121 and 122 in the scenario according to FIG Figure 1b is impaired (e.g. difficult). Accordingly, the radio communication interference area can be determined in step 501, for example, such that the detection positions 118, 121 and 122 are located outside the radio communication interference area or on the edge of the radio communication interference area. For example, the radio communication area is a rectangle, a polygon, an ellipse or a circle, and is determined such that the detection positions 118, 121 and 122 are outside the radio communication interference area or on the edge of the radio communication interference area. An example of such an elliptical radio communication interference area 123 is shown in FIG Figure 1b shown.

In an optional step 502, a large number of commercial vehicle position information items are received and / or held ready, each of the large number of commercial vehicle position information items representing a current position of a respective commercial vehicle of a large number of commercial vehicles.

The fact that each of the plurality of utility vehicle position information represents a current position of a respective utility vehicle of the plurality of utility vehicles is to be understood, for example, in such a way that the plurality of utility vehicle position information only contains the last utility vehicle position information received for the respective utility vehicle. The commercial vehicle position information can be received, for example, via a communication path (e.g. as part of radio interference signal detection information) and then stored in the program memory 301 of the server 3. Accordingly, the provision of commercial vehicle position information should be understood to mean the storage of the commercial vehicle position information.

In the following, it is assumed that the large number of commercial vehicle position information items for each of the semi-trailers 101 to 105 each contain commercial vehicle position information that represents a current commercial vehicle position. These current commercial vehicle positions are for the semitrailers 101, 102 and 103 in the scenario according to FIG Figure 1b For example, the detection positions 118, 121 and 122 represented by the radio interference signal detection information received in step 500. Since the semi-trailers 104 and 105 in this scenario cannot exchange information with the server 3 via the respective communication paths 114 and 115 in step 500 The current commercial vehicle positions for the semi-trailers 104 and 105, for example, by radio interference signal detection information that was received last and / or already before step 500 (e.g. before activating the jammer 116), represented detection positions 119 and 120.

As disclosed above, based on this large number of commercial vehicle position information, it can be determined, for example, whether one or more other commercial vehicles (e.g. a large number of commercial vehicles) are at a predetermined distance from the first detection position 118 (or the second detection position 121 or the third detection position 122). is / n if it is determined in step 500 that the reception of the radio signal at the first detection position 118 (or the second detection position 121 or the third detection position 122) is impaired (eg made more difficult). The server 3 can then request radio interference signal detection information, for example, from each of these additional commercial vehicles. In the scenario according to Figure 1b are these, for example, the semi-trailers 104 and 105, so that of the Radio communication devices 2-4 and 2-5 of the semi-trailers 104 and 105 could request a respective radio interference signal detection information. Since the semitrailers 104 and 105 cannot exchange any information with the server 3 via the respective communication paths 114 and 115, the server 3 does not receive a response in the form of respective radio interference signal detection information to such a request.

In an optional step 503, it is determined at least partially based on the plurality of utility vehicle position information whether at least one utility vehicle of the plurality of utility vehicles is located within the radio communication interference range.

The determination of whether at least one utility vehicle of the plurality of utility vehicles is located within the radio communication interference area can take place in accordance with predefined rules. For example, it can be specified that it is determined that a utility vehicle of the plurality of utility vehicles is located within the radio communication interference area if the respective utility vehicle position information of the plurality of utility vehicle position information represents a position within the radio communication interference area as the current position of this utility vehicle. This is in accordance with the scenario Figure 1b This is the case, for example, for the semi-trailers 104 and 105, the current commercial vehicle positions 119 and 120 of which are within the radio communication interference area 123 determined in step 501. Furthermore, it can be specified that it is determined that a utility vehicle of the plurality of utility vehicles is located within the radio communication interference area if the server does not receive a response in the form of radio interference signal detection information to a corresponding request from the radio communication device of the utility vehicle of the plurality of utility vehicles. This is also in accordance with the scenario Figure 1b this is the case, for example, for semi-trailers 104 and 105.

If it is determined that at least one commercial vehicle of the plurality of commercial vehicles is located within the radio communication interference area, it is assumed, for example, that this commercial vehicle is located in the coverage area of a jammer and thus there is an increased risk of cargo theft of the commercial vehicle (i.e. the commercial vehicle is endangered). Because such jammers often come to the theft Use to prevent radio communication from the commercial vehicle (e.g. with the emergency number 124).

It is therefore provided that if it is determined that at least one commercial vehicle of the plurality of commercial vehicles is located within the radio communication interference area, an alarm action is carried out in an optional step 504 or an alarm action is carried out.

As disclosed above, an alarm action can notify a user such as the emergency number 124 or one or more drivers of utility vehicles who are in the vicinity of the endangered utility vehicle (e.g. within an area with a predetermined radius around the current position of the endangered utility vehicle) , or the dispatcher 124 responsible for the commercial vehicle at risk. For example, in step 504 the server 3 could notify the dispatcher (s) 124 responsible for the semi-trailers 104 and 105.

Alternatively or additionally, an alarm action can be an action carried out by one or more commercial vehicles that are in the vicinity of the commercial vehicle at risk (e.g. within an area with a predetermined radius around the current position of the commercial vehicle at risk), such as activating the hazard warning lights and / or the low or high beam and / or a horn of the respective commercial vehicle. For example, the server 3 could send respective control information to the radio communication devices 2-1 to 2-3 of the semi-trailers 101 to 103 via the communication paths 111, 112 and 113; which cause the respective radio communication device to control the respective semitrailer in such a way that the hazard warning lights of the respective semitrailer are activated.

The invention thus enables the detection of the jammer 116 based on the radio signal parameters detected by the semitrailers 101, 102 and 103 and the risk associated with the jammer 116 for the semitrailers 104 and 105, so that measures in the form of the alarm action (s) to minimize the Endangerment of the semitrailers 104 and 105 can be taken, although the semitrailers 104 and 105 themselves cannot communicate. In addition, the detection can also include the lack of a response to the request for respective radio interference signal detection information disclosed above of the radio communication devices 2-4 and 2-5 of the semi-trailers 104 and 105 through the server 3.
