COMMUNICATION DEVICE, CONTROL COMPONENT, METHOD AND COMPUTER PROGRAM FOR CONFIGURING LOCAL WIRELESS COMMUNICATION BETWEEN THE COMMUNICATION DEVICE AND A VEHICLE-NEARING MOBILE DEVICE

Description

Technical field

[0001] Exemplary embodiments of the present invention relate to a communication device, a control component, a mobile station, a vehicle, a system, methods, and computer programs for configuring local wireless communication between the communication device and a vehicle-mounted mobile device. In particular, but not exclusively, additional frequency bands are configured or provided for a cellular vehicle-mounted application. background

[0002] It is known for providing communication protocols and a frequency band for a cellular vehicle-to-entity (C-V2X) application, enabling the exchange of information between moving vehicles and other entities. This application is standardized, for example, by the 3rd Generation Partnership Project (3GPP). According to the 3GPP TS (Technical Specification) 36.101 standard, a frequency band at 5.9 GHz (Band 47) is allocated for this communication. This band is reserved for this purpose and is not used for mobile communication via stationary system elements such as base stations, network controllers, or the like, thus preventing mutual interference. The C-V2X application operates the band in broadcast mode, allowing all receivers within range to pick up the transmitted information.

[0003] For communication in vehicles or their surroundings, existing systems such as Bluetooth, Bluetooth Low Energy, or Wi-Fi are frequently used. However, these suffer from the problem that the available frequency spectrum is limited and cannot be reliably allocated to specific devices. Furthermore, all three technologies compete for the same frequency spectrum (ISM – Industrial, Scientific, and Medical – bands at 2.4 GHz and 5.8 GHz). This means that communication using these technologies in or around the vehicle is not always reliable, or in the worst case, can fail completely, for example, near numerous Wi-Fi hotspots or when many devices are simultaneously performing interference-inducing functions such as Bluetooth paging.

[0004] A high-performance and uninterrupted point-to-point connection is also of great importance for the "platoon driving" method of, for example, trucks, which is supported by cellular mobile communications, especially for safety functions.

This includes cooperative communication between multiple on-board units in respective vehicles and scanning the vehicle access network to capture coverage of at least one infrastructure access point.

Each of the superconducting filters is followed (subordinate to) an analog-to-digital converter (ADC) with interfaces for further processing.

[0018] Note that an element described as "connected" or "coupled" to another element may be directly connected or coupled to that element, or there may be intervening elements. Conversely, if an element is described as "directly connected" or "directly coupled" to another element, there are no intervening elements. Other terms used to describe the relationship between elements should be interpreted similarly (for example, "between" versus "directly between," "adjacent" versus "directly adjacent," etc.).

[0019] The terminology used herein serves only to describe specific embodiments and is not intended to limit the embodiments. As used herein, the singular forms "a," "an," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise. Furthermore, it should be clarified that expressions such as "includes," "containing," "exhibits," "comprises," "comprehensive," and / or "indicating," as used herein, indicate the presence of the aforementioned features, integers, steps, processes, elements, and / or components, but do not preclude the presence or addition of one or more features, integers, steps, processes, elements, components, and / or groups thereof.

[0020] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning that an average person skilled in the field to which the examples of implementation belong would ascribe to them. Furthermore, it should be clarified that expressions, for example, those defined in commonly used dictionaries, are to be interpreted as having the meaning consistent with their meaning in the context of the relevant technology, and not in an idealized or overly formal sense, unless expressly defined herein.

[0021] The components described here and below are described as "designed to" or "configured to" perform or fulfill a certain function, with these terms being used synonymously and interchangeably. Each such component is capable of performing the described function because, for example, the corresponding software is present or stored in memory. For instance, a control module designed or configured to control a transceiver module and implemented in programmable hardware must be designed such that appropriate control software for controlling the transceiver module is present.

[0022] Fig. 1 Figure 10 illustrates an embodiment of a communication device 10 for configuring local wireless communication between the communication device 10 and a vehicle-mounted mobile device 300 / 310, or between vehicle-mounted mobile devices 300 / 310 of a mobile communication system. The communication device 10 comprises a transceiver 12 configured for communication with a control component 20 of the mobile communication system. The communication device 10 further comprises a control module 14, which is coupled to the transceiver 12 and configured for controlling the transceiver 12. The control module 14 is further configured to communicate in a first frequency band within the mobile communication system in order to obtain a configuration of a second frequency band of the mobile communication system for local wireless communication.The control module 14 is further designed to communicate the configuration for local wireless communication in the second frequency band to at least one vehicle-adjacent mobile device 300 / 310 of the mobile communication system 1200.

[0023] In exemplary embodiments, the communication device 10 can be configured for operation in accordance with the cellular vehicle entity C-V2X standard. Furthermore, in exemplary embodiments, the communication device 10 can be arranged in a vehicle 100. Another exemplary embodiment of a mobile station or a vehicle 100 with an exemplary embodiment of a communication device 10 is described in the Fig.1 also shown.

[0024] Fig. 1 Figure 1 shows an embodiment of a control component 20 of a mobile communication system for configuring local wireless communication between a communication device 10 and vehicle-mounted mobile devices 300, 310, or between vehicle-mounted mobile devices 300, 310 of a mobile communication system. The control component 20 comprises a transceiver 22 configured for communication with the communication device 10 of the mobile communication system and a control module 24 coupled to the transceiver 22 and configured to control the transceiver 22. The control module 24 is further configured to communicate in a first frequency band within the mobile communication system and to transmit a configuration of a second frequency band of the mobile communication system for local wireless communication. This enables the communication device to be used with at least one vehicle-mounted mobile device 300, 310, or between vehicle-mounted mobile devices 300, 310.Forwarding the configuration for local wireless communication in the second frequency band to at least one vehicle-proximity mobile device 300, 310 of the mobile communication system is provided. Further embodiments include a base station, a network controller, and a network server, each comprising an embodiment of the control component 20. In these embodiments, the control components of the mobile network can be configured as a base station, a network controller, and / or a server. These components have different functionalities and different arrangements within the network component structure according to the 3GPP 2G-5G standards. Another embodiment is a system, for example, a mobile communication system, with a communication device 10 and a control component 20.

[0025] In exemplary embodiments, a transmit-receiver 12, 22 can comprise typical transmit-receiver components, such as one or more low-noise amplifiers (LNAs), one or more power amplifiers (PAs), one or more duplexers, one or more diplexers, one or more filters or filter circuits, one or more converters, one or more mixers, appropriately matched radio frequency components, etc. The antennas can correspond to any transmit and / or receive antennas, such as horn antennas, dipole antennas, patch antennas, sector antennas, etc. The antennas can be arranged in a defined geometric configuration, such as a uniform array, a linear array, a circular array, a triangular array, a uniform field, an array, or combinations of these configurations.

[0026] The control module 14, 24 can correspond to any controller, processor, or programmable hardware component in exemplary embodiments. For example, a control device / module 14, 24 can also be implemented as software programmed for a corresponding hardware component. In this respect, a control module 14, 24 can be implemented as programmable hardware with appropriately adapted software. Any processor, such as digital signal processors (DSPs), can be used. Exemplary embodiments are not limited to a specific type of processor. Any processor, or even multiple processors or microcontrollers, are conceivable for implementing the control module. Integrated implementations with other control units are also conceivable, for example, in a control unit for a vehicle that additionally includes one or more other functions.The process steps described herein can be carried out in exemplary embodiments by the control modules 14, 24 or by or via the respective transmitters 12, 22. In this respect, the described process steps can be performed by the device components. In exemplary embodiments, a control module 14, 24 can be implemented by a processor, a computer processor (CPU = Central Processing Unit), a graphics processor (GPU = Graphics Processing Unit), a computer, a computer system, an application-specific integrated circuit (ASIC = Application-Specific Integrated Circuit), an integrated circuit (IC = Integrated Circuit), a system-on-a-chip (SOC = System on Chip), a programmable logic element, or a field-programmable gate array with a microprocessor (FPGA = Field Programmable Gate Array).

[0027] In exemplary embodiments, a transceiver, mobile communication device, or mobile device is adapted to a radio system, a mobile communication system, or a mobile communications system in the sense that it has the components required for such communication, such as antennas, filters, amplifiers, one or more processors, a display, etc. Such systems include, for example, Bluetooth, Wireless Local Area Network (WLAN), Wireless Fidelity (WiFi), mobile communications, etc. Mobile communication systems that are standardized by relevant standardization bodies, such as the 3rd Generation Partnership Project (3GPP), are also relevant. These include, for example, the Global System for Mobile Communications (GSM), Enhanced Data Rates for GSM Evolution (EDGE), GSM EDGE Radio Access Network (GERAN), the Universal Terrestrial Radio Access Network (UTRAN), or Evolved UTRAN (E-UTRAN), such as...The term "mobile communication system" refers to the Universal Mobile Telecommunication System (UMTS), Long Term Evolution (LTE), LTE-Advanced (LTE-A), fifth-generation (5G) systems, or mobile communication systems of other standards, such as Worldwide Interoperability for Microwave Access (WiMAX), IEEE 802.16, or Wireless Local Area Network (WLAN), IEEE 802.11, as well as generally any system based on a time-domain multiple access method (TDMA), frequency-domain multiple access method (FDMA), code-domain multiple access method (CDMA), orthogonal frequency-domain multiple access method (OFDMA), or another technology or multiple access method. The terms mobile communication system, mobile network, and mobile communication system are used synonymously in the following text.

[0028] In the following, it is assumed that such a mobile communication system includes at least one stationary transceiver in the sense of a base station, which is connected to the wired part of the mobile network. On the other hand, it is assumed that the mobile network includes at least one mobile transceiver (mobile device, mobile terminal), where the term "mobile" refers to the fact that this transceiver communicates wirelessly via the air interface. Such a mobile transceiver could be, for example, a portable telephone, a smartphone, a tablet computer, a laptop, a vehicle, or a radio module, which is not necessarily mobile in the sense that it actually moves relative to its environment. The transceiver could also be stationary (e.g., relative to a vehicle) but communicate wirelessly with the mobile network.Therefore, the aforementioned base station can conform to one of the standards mentioned above, for example a NodeB, an eNodeB, etc.

[0029] In this regard, concepts for direct communication between mobile communication devices are known, also referred to as D2D (device-to-device communication). Standardization has led to extensions of this to communication between vehicles. Examples include 3GPP V2V (vehicle-to-vehicle) communication as part of the C-V2X standard with the PC5 interface, or car-to-car communication with the 802.11p interface. In exemplary implementations, one of these systems can be used, and the communication device 10, or its transceiver 12 and control module 14, can be adapted accordingly. This applies analogously to the infrastructure-side control module 20 and its components.

[0030] In exemplary embodiments, a frequency band can be suitable for operating a cellular mobile communication system. It can be designed for unidirectional or bidirectional communication. For example, it can be divided into an uplink and a downlink component at different frequencies, with each subband having a certain bandwidth, e.g., 5 MHz, 10 MHz, 50 MHz, 70 MHz, etc. It can be designed for broadcast communication, communication between selected subscribers, and / or point-to-point operation. In exemplary embodiments, frequency bands can be allocated according to the 3GPP plan, where band 47 at 5.9 GHz is designated for C-V2X. The bands can be designated for TDD (Time Division Duplex) or FDD (Frequency Division Duplex) mode and configured according to the PC5 interface for vehicles according to C-V2X.

[0031] The V2V range can be several hundred meters in exemplary embodiments, for example, between 350 and 700 meters. In these embodiments, direct communication can be implemented as point-to-point communication, where signal exchange between the participating units occurs without intermediaries. A mobile device located near the vehicle can be inside the vehicle or in an area surrounding the vehicle, the size of which is determined by the range of the PC5 interface signals, which is typically several hundred meters (see above). In these embodiments, bidirectional communication can involve data transmission in both directions of a point-to-point connection. Signals or information can be exchanged alternately or simultaneously in both directions. In other words, the subject of these embodiments also includes in-vehicle communication using the V2X standard and its extensions.

[0032] In exemplary embodiments, a mobile station can be designed as a communication device with additional components to ensure an agreed-upon interface and characteristics. For example, a vehicle-neutral interface can be defined, specifying not only the arrangement and meaning of individual signals but also limits power consumption or a minimum transmission power. A connector to the vehicle can also be defined. The characteristics can be standardized. The system can be implemented as the sum of all components of the mobile communication system, encompassing all necessary functions and features for operation. For instance, the system can be designed according to one of the 3GPP standards (2G-5G). In exemplary embodiments, mobile devices can be portable devices such as mobile phones, tablets, laptops, portable computers, or radio modules, or the like.They can also be integrated into clothing or accessories, for example as glasses, a USB modem, or similar items. Mobile devices, also called handheld devices, can also be assigned to users if the mobile devices are capable of communicating user data.

[0033] The Fig. 1 Figure 1 shows an embodiment of a method for a communication device 10 for configuring local wireless communication 1300 / 1310 / 1400 between the communication device 10 and a vehicle-mounted mobile device 300 / 310 or vehicles-mounted mobile devices 300 / 310 of a mobile communication system. The method comprises communication 1000 / 1100 in the mobile communication system in a first frequency band for configuring a second frequency band of the mobile communication system for local wireless communication. The method further comprises communication 1200 of the configuration for local wireless communication in the second frequency band to at least one vehicle-mounted mobile device of the mobile communication system.

[0034] In exemplary embodiments, the communication can include a request 1000 from the communication device for the second frequency band, and the receipt of an acknowledgment 1100 of an allocation of the second frequency band.

[0035] Furthermore, in exemplary embodiments, the vehicle-mounted mobile device 300 / 310 can be arranged in a vehicle 100, or outside the vehicle 100 within a vehicle-to-vehicle V2V communication range of a PC5 interface, for example in another vehicle.

[0036] Furthermore, in exemplary embodiments, the control component 20 of the mobile network can be configured as a base station, as a network controller, and / or as a server. The exemplary embodiment according to Fig. 2 Figure 1 shows a block diagram of a method for a communication device 10 for configuring local wireless communication between the communication device 10 and a vehicle-mounted mobile device 300 / 310 or devices 300 / 310 of a mobile communication system. This includes communication 410 in the mobile communication system in a first frequency band for configuring a second frequency band of the mobile communication system for local wireless communication. The method further includes communication 420 of the configuration for local wireless communication in the second frequency band to at least one vehicle-mounted mobile device 300 / 310 of the mobile communication system.

[0037] The exemplary embodiment according to Fig. 3 Figure 1 shows a block diagram of a method 500 for a control component 20 of the mobile communication system for configuring local wireless communication between a communication device 10 and vehicle-mounted mobile devices 300 / 310 or between vehicle-mounted mobile devices 300 / 310 of a mobile communication system. The method comprises communication 510 in the mobile communication system in a first frequency band for configuring a second frequency band of the mobile communication system for local wireless communication from the communication device to at least one vehicle-mounted mobile device 300 / 310 or between vehicle-mounted mobile devices 300 / 310 for communicating the configuration for local wireless communication in the second frequency band to at least one vehicle-mounted mobile device 300 / 310 of the mobile communication system.

[0038] In another embodiment, the method and the derived implementation build upon the system for direct communication using C-V2X communication according to the 3GPP Release 14 standard. This system was developed with a view to increasing road safety. It therefore uses a message broadcast system and an authentication backend to ensure the reliability of the information. Embodiments can extend this system. For example, the current 3GPP Release 14 standard (TS 36.101 Section 5.5G) uses a harmonized frequency band (ITS band in Europe, DSRC band in the US, 3GPP Band 47) around 5.9 GHz for transmitting the broadcast information described above; in embodiments, this corresponds to the second frequency band.The existing 3GPP standard is based on a message broadcast system, i.e., unidirectional communication, which can be extended to bidirectional communication through exemplary implementations. For example, in exemplary implementations, the transmitter-receivers 12, 22 can be configured to use the first and second frequency bands.

[0039] In exemplary embodiments, the second frequency band can be configured as a broadcast frequency band for direct communication or for bidirectional communication between mobile devices of the mobile communication system. For example, a request to use the second frequency band 1000 is sent from a vehicle 100, which includes an exemplary embodiment of a communication device 100, to a network controller 200, which includes an exemplary embodiment of the control component 20. The network controller 200 can then allocate the frequency band 1100, and the communication device 10 in the vehicle 100 can now use the second frequency band. For example, the use of the second frequency band can be passed on to two UEs or mobile devices 300, 310. A conceivable scenario is in a car, bus, train, etc.The communication device 10 is permanently installed in the vehicle and makes the second frequency resource available to passengers in the vehicle for use (e.g., video sharing, games, etc.). In some embodiments, the second frequency band can also be used by the communication device 10 itself, for example, for radio communication with other vehicles in the sense of V2V messages. In this respect, other vehicles can also be configured to use the second frequency band. The mobile device 300, 310 can therefore be configured as a portable mobile device or as an additional communication device installed in the vehicle.

[0040] The control module 14 can therefore be configured to establish direct communication between the communication device 10 and the at least one vehicle-mounted mobile device 300, 310, or between at least two vehicle-mounted mobile devices 300, 310 of the mobile communication system using the second frequency band. Accordingly, in exemplary embodiments, the transceiver 12 and / or the control module 14 can be configured to enable the at least one mobile device 300, 310 in its vicinity to use services (voice and data services) of the mobile communication system. The use of mobile network operator frequencies for in-vehicle communication can allow the integration of mobile network operator services.

[0041] The secure connection transmission already present in the 3GPP standard (encryption, authentication) can also allow the communication of sensitive content and the operation of system-critical functions to be carried out via a radio interface. In exemplary embodiments, the first and second frequency bands of the cellular mobile communication standard can include frequency bands used by the 3GPP LTE standard. A security measure for bidirectional communication can accordingly include an authentication function and / or an encryption function. In at least some exemplary embodiments, the control module 14 can be configured to enable the time- and / or location-limited agreement of certificates to secure the communication.In general, the communication device 10 can include, in exemplary embodiments, a safeguard for bidirectional communication, an authentication function and / or an encryption function.

[0042] As shown by the Fign. 1-3 The explanatory examples demonstrate methods and implementations for potentially utilizing existing communication hardware for communication within a vehicle or its surroundings. Existing in-vehicle communication systems such as Bluetooth, Bluetooth Low Energy, or WiFi can suffer from the problem that the available frequency spectrum is limited and cannot be reliably allocated to specific devices. Furthermore, all three technologies compete for the same frequency spectrum (ISM bands 2.4 GHz and 5.8 GHz). This results in communication using these technologies within the vehicle not always being fully reliable, or in the worst case, potentially failing completely and temporarily.For example, this occurs near numerous WLAN (Wireless Local Area Network) hotspots in urban areas, or when many devices simultaneously perform interference-inducing functions such as Bluetooth paging. This makes it impossible to implement applications with very high data rates, such as video streaming to multiple clients with different content or virtual reality applications in vehicles. In some implementation examples, the clients can be run as software applications (APPS) on a mobile device (300, 310).

[0043] In exemplary implementations, the method and the derived implementation can be based on the future system for direct communication using C-V2X communication according to Release 14 of the corresponding 3GPP standard. This system has been developed with a view to increasing road safety. The 3GPP Release 14 standard (TS 36.101 Section 5.5G) uses a harmonized frequency band (ITS (Intelligent Transportation Systems) band in Europe, DSRC (Distributed Routing and Centralized Scheduling) band in the USA, 3GPP Band 47 at 5.9 GHz) for transmitting the broadcast information described above. Implementation examples can extend this usability of V2X communication to other 3GPP frequency bands, such as Band 41 (2600 MHz), Band 42 (3500 MHz), or Band 43 (3700 MHz). In these implementation examples, the second frequency band can be located at 900 MHz, 1900 MHz, 2600 MHz, 3500 MHz, or 3700 MHz.

[0044] When using frequency bands subject to licensing, the licensor is integrated into the system. The existing standard for frequency management of band 47 by mobile network operators (also called operators) can be used in exemplary implementations to negotiate the temporally or spatially restricted use of licensed frequencies with limited power. In exemplary implementations, the use of the second frequency band of the cellular mobile communications standard can be limited in time and / or space within the permissible transmission power. This enables the control component 20, or the control module 24 contained therein, to perform resource monitoring, resource planning, and resource management.

[0045] In some further embodiments, it is also conceivable to enter into a prior agreement with a specific operator or provider through a subscription, for example, to use portions of their LTE frequencies for in-vehicle communication at reduced transmission power. These portions of the LTE spectrum can then be used for communication between the communication device 20 and a vehicle-mounted mobile device 300, or for communication between vehicle-mounted mobile devices 300 and 310. In some embodiments, a prior subscription with a cellular mobile network operator may predetermine the second frequency band. In other embodiments, a subscription may correspond to a license to use, in this case, a license to use a frequency band or a portion of a frequency band of an operator, for example, for C-V2X operation.The license can be specified in terms of time, location, maximum permitted transmission power, or time of day.

[0046] The necessary modification to the hardware design of the V2X communication unit can be implemented simply by adding one or more filters and signal amplifiers. This will be demonstrated using the following: Fign. 4 , 5 and 6 will be explained in more detail. Fig. 4 Figure 1 shows a communication device for cellular mobile communications according to the standards of the 2nd to 5th generation (2G-5G) as standardized by the 3rd Generation Partnership Project (3GPP). This communication device comprises a digital modem 610 for the digital processing of the signals to be transmitted and received according to the relevant standards. The digital modem 610 is connected or coupled to a transceiver 620, which performs the high-frequency processing of the modem signal and the received signals. The transceiver 620 is in turn connected to the front end 650, which contains filter elements for filtering the RF (radio frequency) bands of the aforementioned 2nd to 5th generation standards according to 3GPP, as well as corresponding amplifiers (PAs, LNAs).

[0047] Separately, a communication device for C-V2X is shown, comprising the corresponding components. The digital modem 630 is used for the digital processing of the signals to be sent and received according to the C-V2X standard. The digital modem 630 is connected to a transceiver 640, which performs the high-frequency processing of the modem signal and the received signals. The transceiver 640 is in turn connected to the front end 660, which contains filter elements for filtering as well as corresponding amplifiers for the frequency band of the C-V2X standard.

[0048] The exemplary embodiment according to Fig. 5 Figure 1 shows a transceiver 12 of a communication device 10. Components 610, 620, 630 and 640 have the following features: Fig. 4 described functions. Deviating from Fig. 4 In this embodiment, however, there is only one frontend 670, which is designed for all frequency bands. Consequently, signals from the frequency bands according to the standards of the 2nd to 5th generation of cellular mobile communications can also be used for the C-V2X standard. The frontend 670 includes the additional filters and amplifiers required for the C-V2X frequency band.

[0049] Fig. 6 Figure 8 shows another embodiment of a communication device 800 with connected transceivers for local devices, which are implemented as a GPS module 840, a Bluetooth module 842, and a WLAN module 844. The connection to the communication device 800 is established via an interconnect system 830, which can, for example, be configured as an internal bus system.

[0050] The Communication Unit 800 comprises a Cellular RF (Radio Frequency) Receiver 810 for transmitting and receiving radio signals according to the standards and frequency bands of the 2nd to 5th generation of cellular mobile communications. The Cellular RF Receiver 810 is coupled with a C-V2X Modem 822, which includes a memory and a microcontroller (MCU) for processing the transmit and receive signals according to the respective mobile communications standard.

[0051] The C-V2X modem 822 is coupled to a secure element 820 for storing security-relevant data, which is protected against unauthorized access. Furthermore, the C-V2X modem 822 is coupled to the connection system 830. The transceiver 810 is further coupled to a modem 824 for processing signals according to the standards of the 2nd to 5th generation of cellular mobile communications. The modem 824 comprises a digital signal processor (DSP), another processor (MCU), and memory. The C-V2X modem 822, the cellular RF receiver 810, and the baseband modem 824 correspond to the transceiver 12 and the components 610, 620, 630, 640, and 670 from [reference missing]. Fig. 5 The communication unit 800 further comprises a SIM (Subscriber Identity Module) card 812 in the associated reader to support the communication functions, one or more display units 814 (LCDs), an external memory 816 (Ext. Mem), and a connection option for external devices 818 (Peripherals). An application processor 826 comprises several processors (MCUs) and memory. It is coupled to the connection system 830. A power supply 828 is also coupled to the connection system 830.

[0052] The GPS module 840, the Bluetooth module 842 and the WLAN module 844 each include a memory, a processor (MCU) and a transmit / receive module according to the respective standard.

[0053] In the Fig. 6 The arrows indicate the procedure in one embodiment. The C-V2X modem 822 is configured for environmental communication (direct communication) according to an agreement with a network operator via SIM credentials (identifiers stored on the SIM card). The cellular RF transceiver (modem) 810 can then be configured according to the Fig. 5to be modified. Exemplary embodiments also provide for the extension of a broadcast component to include the component for bidirectional communication at ISO (International Organization for Standardization) layers 1-3. In exemplary embodiments, the control module 14 can also initiate bidirectional communication between the communication device 10 and at least one vehicle-mounted mobile device 300 / 310, or between vehicle-mounted mobile devices 300 / 310 of the mobile communication system, for example, based on a physical layer, a data link layer, and / or a network layer according to the Open Systems Interconnection (OSI) model.The control module 14 can initiate bidirectional communication between the communication device 10 and at least one vehicle-mounted mobile device 300 / 310, or between vehicle-mounted mobile devices 300 / 310 of the mobile communication system, based on a transport layer, a session layer, and / or a presentation layer according to the Open Systems Interconnection (OSI) model. Alternatively, bidirectional communication can also be implemented at higher ISO / OSI layers, independent of the underlying mobile communication standard.

[0054] Dedicated resources can be allocated based on the required data rate and the desired QoS (Quality of Service), and specifically assigned to a particular wireless connection between two participants. In practical examples, a data rate can be understood as the transmission speed or transmission rate. This refers to the number of units of information transmitted over a given time via the transmission medium, interface, or channel. In practical examples, QoS (Quality of Service) can be understood as the quality of a communication service from the user's perspective. It indicates how closely the service quality meets the user's requirements. In practical examples, QoS consists of a multitude of quality requirements regarding the combined behavior or interaction of multiple units.

[0055] In exemplary embodiments, resources of the second frequency band of the mobile communication system can be allocated, for example, depending on a data rate and / or a Quality of Service (QoS). The use of mobile network operators' frequencies for in-vehicle communication can also allow the integration of mobile network operator services. The communication device 10 can therefore be configured to enable at least one mobile device 300, 310 in its vicinity to use services (voice services, video services, data services) of the mobile communication system.

[0056] For example, the secure connection transmission already present in the 3GPP standard (encryption and authentication) can also allow the communication of sensitive content and the operation of system-critical functions via a wireless interface. In exemplary implementations, the authentication system of direct communication can be used and extended with the option of obtaining temporary and locally limited certificates from the network operator to secure the communication. In these exemplary implementations, a security measure for bidirectional communication can include an authentication function and / or an encryption function. The control module 14 can then be configured to enable the time- and / or location-limited agreement of certificates to secure the communication.

[0057] In some embodiments, authentication can be proof (verification) of a claimed property of an entity, which might, for example, be a device. The verification of the claimed property is carried out through a suitable process, which in some embodiments may be based on a secret key. The property could be the identity of the device. In other embodiments, encryption can be implemented as the key-dependent conversion of data called "plaintext" into "ciphertext," such that the plaintext can only be recovered from the ciphertext using a secret key. This protects data against unauthorized access.

[0058] In some examples, a certificate can be understood as a digital data record that confirms certain properties of persons or objects and whose authenticity and integrity can be verified using cryptographic methods. The certificate contains, in particular, the data required for its verification. Certificates are issued by a certification authority. In other examples, an authentication backend can be understood as a system that performs local authentication in a secure environment and makes the result available for comparison with a remote authentication operation.
