    The invention relates to a communication system for voice communication according to the preamble of claims 1 and 14 and a method for voice communication according to the preamble of claims 27 and 41. In such a communication system is substantially provided that voice signals and signaling information PTT / SQU of one or more workstations to one or more radio devices and vice versa can be transmitted.
    In air traffic control, the size of the communication system and also the geographical distribution of the individual components required can be very different. Small systems, such as tower systems, may consist of a few workstations and a few radio transmitters and radio receivers, which may even be housed in the same building. Size systems, such as air traffic control centers, may consist of many hundreds of work stations and correspondingly many radio transmitters and radio receivers in geographically dispersed locations, and depending on the configuration of the communication system, each workstation may communicate with each radio. For radio operation, the air traffic controller at work can select the frequencies necessary for his operation, which he wants to discuss during TX operation and / or listen in RX mode. For the transmission of speech signals, an operating unit 113, 123, 133 is actuated, in particular PTT-key pressed, in which case in addition to the recorded at the workplace speech signals and a PTT signal to a radio transmitter 51, 52, 53 is transmitted. Due to the PTT signal, RF transmission with the modulated speech signal is performed at the radio transmitter 51, 52, 53. If an RF signal is received by a radio receiving device 61, 62, 63, the demodulated voice signal is transmitted to the workstations 11, 12, 13 together with a received signal SQU. Speech signals received at a frequency selected by the workstation are output on the loudspeaker or in the headset of this workstation 11, 12, 13 and the associated received signal SQU is recorded at the workstation, e.g. on the graphical user interface.
    In addition, an air traffic controller may couple at least two or more frequencies together, in which case all audio signals received by a radio receiving device 61, 62, 63 associated with one of the coupled frequencies are transmitted on the radio transmitters 51, 52, 53 of the other frequencies become.
    Which frequencies an air traffic controller can actually select depends on the configuration of the workstation 11, 12, 13, whereby this configuration can also be exchanged.
    An example of a communication system known from the prior art is shown in greater detail in FIG. A conventional radio workstation 11, 12, 13 known from the prior art may comprise an electronic unit or a PC, which is provided with a touch panel for operation, a microphone 111, 121, 131, a control unit 113, 123, 133 for the triggering of the PTT signal, a headset 112, 122, 132 and an optional speaker is equipped. As far as a radio device is generally referred to, this is understood to mean a radio transmitter or a radio receiver or a combined radio transmitter and receiver. In the event that each workstation 11, 12, 13 establishes a direct communication relationship with a radio transmitter or receiver, the radio transmitter 51, 52, 53 performs the arbitration of the voice signal to be transmitted and the radio receiver 61, 62, 63 distributes the received voice signals to those workstations 11, 12, 13, which have keyed this frequency. Each signal transmission between a workstation 11, 12, 13 and a radio device each comprises a voice signal and associated signaling information PTT or SQU, which is transmitted simultaneously with the voice signal. In a signal transmission from a workstation 11, 12, 13 to a radio transmitter, the presence of the voice signal is signaled by an operating signal PTT. The signal transmission between the radio receiving device 61, 62, 63 to a workstation 11, 12, 13 also includes a received signal SQU after the voice signal.
    An example of possible communication relationships between workstations 11, 12, 13 and radio transmitter 51, 52, 53 and radio receiver 61, 62, 63 is shown in FIG. 1, wherein each workstation 11, 12, 13 has any number of radio transmitters 51 corresponding to its operational configuration , 52, 53 and
    Radio receiving devices 61, 62, 63 can be assigned. In extreme cases, this results in a m n communication relationships between m workstations 11, 12, 13 and n radio transmitters 51, 52, 53 and radio receiving devices 61, 62, 63. This results in the problem that if a work 11, 12, 13 on n
    Radio transmitters 51, 52, 53 simultaneously emits a voice signal that n audio streams must be sent from the workplace. This is the necessary
    Bandwidth for each individual workstation 11, 12, 13 depends on how many radio transmitters the voice signal of the workstation is transmitted at the same time in the case of a radio transmission, or how many radio reception equipment are monitored by this workstation at the same time. For a radio transmitter, on the other hand, the problem arises that in the case of a simultaneous transmission of multiple workstations, a plurality of voice signals must be transmitted to the radio transmitter, one of which is selected for actual transmission. In the receiving direction, radio reception equipment must transmit a voice signal to the workstation for each workstation that listens to this radio reception equipment. The necessary bandwidth of each radio device is thus dependent on how many workstations 11, 12, 13 at the same time a voice signal to a
    Send radio transmitter 51, 52, 53 and how many workstations 11, 12, 13, the received audio signal of this radio receiving device 61, 62, 63 simultaneously listen.
    In modern radio communication systems for local applications, the communication relationships between the workstations 11, 12, 13 and the radio devices 51, 52, 53, 61, 62, 63 are not made directly, but in a communication system and the workstations 11, 12, 13 and Radio 51, 52, 53, 61, 62, 63 are connected directly to the communication system.
    The aim of the invention is that, regardless of where the air traffic control center and thus his workplace are geographically located, each air traffic controller can access any radio frequency, no matter where it is located geographically. In particular, it is an object of the invention that several air traffic control centers are combined to form a large virtual central, or a central office can take on the tasks of another without the structure of the communication system having to be changed overall. At the same time, the required data rates should be optimized when transmitting the voice signals over the necessary networks.
    The invention overcomes the aforementioned problems in a communication system of the type mentioned above with the characterizing features of patent claim 1.
    In the solution of this problem, the invention can use for the transmission of voice and signaling information over wide area networks WAN, these
    Data networks are dimensioned so that the required blocking freedom and the necessary quality of voice transmission are guaranteed in all operating states of the communication system.
    It is another object of the invention to provide an improved system architecture that adapts the bandwidth and quality requirements for transmission to the existing network and the type of application, particularly for tower, remote tower, ACC or virtual ACC applications ,
    At the same time, the hardware requirements for the workstations 11, 12, 13 should be reduced and it should be possible to spatially concentrate the components of the communication system in data centers 8, wherein the dynamic distribution of audio signals corresponding to the nr.n communication matrix between the workstations 11, 12, 13 and the radio 51, 52, 53, 61, 62, 63 is concentrated in one or more local area networks. The bandwidth requirement in the intermediate wide area networks WAN should be reduced as much as possible. For all components of the communication system that can be dropped over a network, the bandwidth requirement should be deterministic, minimized, and static and / or constant. This can be achieved if each component always sends a defined number of speech signals over the network and the distribution of these speech signals between the components in the local area network takes place in a data center 8.
    In particular, these features enable a virtual ACC application to be implemented, with workstations 11, 12, 13, data centers 8, control units and radio equipment being geographically dispersed in different locations, and all workplaces, regardless of their geographic location, operating on all radio equipment connected via a network Network can be reached, can access. In this case, the necessary data rate in the network is minimized and is deterministic and independent of how many radio transmitter or radio receiver simultaneously discusses or hears a workstation or how many workstations simultaneously discuss a radio transmitter or how many workstations a wireless receiver is monitored. Usually, the bandwidth of the network connections to the individual radio devices is limited, whereby it is not possible to transmit any number of audio signals to a radio equipment and thus allow the radio transmitter to make the selection of the voice signal to be transmitted. Furthermore, radio devices are often only capable of transmitting or receiving one or a few voice signals.
    In the receive direction, it is also not possible that a radio receiving device simultaneously transmits the received voice signal to any number of workstations 11, 12, 13, which want to monitor the same frequency.
    The invention overcomes the aforementioned problems and disadvantages in a communication system of the type mentioned above with the characterizing features of patent claim 1.

This function, which implements the connection of radio transmitter devices and radio receiver devices, is referred to overall as a frequency service and is implemented by a control unit.
    Through the introduction of control devices on which frequency services are implemented, the radio devices are connected directly to the frequency service or the control unit and there is only the transmission of the voice service selected by the frequency service to one or more radio transmitter or the control unit assumes the distribution of the voice signal received by one or more radio receiving devices to the workstations. This also eliminates the need to transmit voice signals from and to the radio equipment compressed to thereby save bandwidth or minimize the required bandwidth or to use in the transmission of audio signals between the workstations and the radio network mechanisms such as multicast, their use over wide area networks WANs is problematic.
    At the same time, several radio devices, which are located at different radio sites and operated at the same physical frequency, can be combined in a frequency service by a common control unit, wherein the selection of the signal to be transmitted and the selection of the radio site takes over the frequency service. The frequency service or the control unit can also take on additional functions and make the functions thus realized available to all users. These include, for example: • the evaluation of the receiver signals with simultaneous reception of a plurality of radio receiver associated with the frequency service due to different quality characteristics of the received signal and optionally an additional optional signal selection, • the dynamic selection of one or more radio transmitters of a frequency in CLIMAX operation for a radio broadcast. This function may also be dependent on a previous reception, referred to as a "transmit follows receiver", • a switch to a spare radio main / standby switch in the event that the active radio is faulty, • dynamic delay time compensation of the runtime of an audio signal between workplace and several radio transmitters of one frequency in CLIMAX operation etc.
    If there are m workstations and n frequency services in a communication system, and each frequency service can in turn combine several radios, then it is possible for each workstation to be able to broadcast on or listen to any number of frequency services simultaneously. This results in a m.n communication matrix between the workplaces and the frequency
    Services or control unit. Which frequency services or control unit a workstation is actually allowed to access is determined by the configuration of the workstations, which can be changed according to the operational requirements. The actual use of a frequency service or control unit depends on the user's keystrokes.
    Some possible implementations of communication systems according to the invention are shown in greater detail in FIGS. 2 to 6.
    Fig. 2 shows schematically the structure of a first embodiment of a communication system according to the invention, wherein control units are provided with frequency services. Fig. 3 shows schematically the structure of a second communication system according to the invention, wherein distribution units are provided which act as a workstation proxy computer. Fig. 4 shows a third embodiment of the invention with a combination of the features shown in FIGS. 2 and 3. Fig. 5 shows a fourth embodiment of the invention, wherein several independent data centers and higher-level control units are provided. Fig. 6 shows an alternative to the third embodiment of the invention, wherein two control units are coupled together.
    There is a logical 1: 1 communication relationship between the frequency service and each individual radio transmitter or radio receiver, whereby the necessary data rate between the frequency service and the radio devices is limited and deterministic, regardless of how many workstations 11, 12, 13 have a frequency resp a distribution unit 31, 32, 33 actually use. Thus, the necessary data rate between the radio devices and the frequency service is minimized, whereby an audio compression of the speech signals on this transmission link is not absolutely necessary.
    The frequency service implemented in the control unit 31, 32, 33 is used for setting up and monitoring the audio connections to the radio transmitter and radio receiver assigned to the frequency service, each frequency service managing a given radio frequency.
    The first embodiment of the invention shown in FIG. 2 comprises a number of workstations 11, 12, 13, which are connected to control units 31, 32, 33 via a wide area network. Each of the workstations has at least one voice input unit 111, 121, 131, in the present case this is a microphone. Furthermore, each workstation has at least one voice output unit 112, 122, 132, which in the present case are in the form of loudspeakers or headphones. Furthermore, the individual workstations 11, 12, 13 have an operating unit 113, 123, 133 with which an operating signal PTT can be created and transmitted in each case. This operating signal indicates that voice signals are to be transmitted from one workstation 11, 12, 13 to one of the radio transmitter devices 51, 52, 53 by means of the voice input unit 111, 121, 131. Furthermore, each of the workstations has a display unit 114, 124, 134 for displaying a receive signal SQU. Furthermore, the workstations have a selector unit, not shown, for selecting those radio transmitter devices 51, 52, 53 and radio receiver devices 61, 62, 63 to which the respective workstation would like to transmit voice signals or from which the respective workstation 11, 12, 13 would like to receive voice signals. The control units 31, 32, 33, which are connected to the workstations 11, 12, 13 via the wide area network WAN, are in turn connected to radio transmitter 51, 52, 52a, 53, 53a and radio receiver 61, 62, 62a, 63, 63a , This means that the control units 31, 32, 33 lie in the signal path between the workstations 11, 12, 13 and the radio transmitter 51, 52, 53 and the radio receiver 61, 62, 63, respectively.
    As already known in the prior art, the speech transmitters 51, 52, 53, the voice signals created by the speech input units 111, 121, 131 and the control signals generated by the control units 113, 123, 133 supplied indirectly via the control units 31, 32, 33 , The radio transmitter 51, 52, 53 is designed to deliver the voice signals transmitted by a workstation 11, 12, 13 while simultaneously transmitting an operating signal PTT by means of radio. Likewise, the radio receiving devices 61, 62, 63 each transmit a received signal SQU during the reception of voice signals and during their transmission to the workstations 11, 12, 13. The radio receiving devices 61, 62, 33 are designed to receive voice signals by radio, wherein the voice signals received by the radio receiving devices 61, 62, 63 from individual work stations 11, 12, 13 are supplied for delivery to the voice output units 112, 122, 132.
    As can be seen from the present first exemplary embodiment, each control unit 31, 32, 33 is in communication with at least one radio transmitter 51, 52, 53 and at least one radio receiver 61, 62, 63. In this advantageous embodiment of the invention, the radio devices 51, 61 assigned to the control unit 31 use the same frequency. Likewise, the radio devices 52, 52a, 62, 62a assigned to the second control unit 32 use a common frequency, and the radio devices 53, 53a, 63, 63a assigned to the control unit 33 also use a common frequency. This measure ensures that the frequency services running in the control units 31, 32, 33 are each used to manage a radio frequency in a specific area. The control units 31, 32, 33 allow simultaneous connection to one or more of the workstations 11, 12, 13 via the wide area network. In particular, all of the workstations 11, 12, 13 can be connected to all control units 31, 32, 33 via the wide area network.
    The control units 31, 32, 33 undertake in the first embodiment of the invention shown in FIG. 2 the task of arbitrating the outgoing speech signals transmitted by the workstations and the speech signals received by the radio receiving devices 61, 62, 62a, 63, 63a to the workstations to distribute. In the simultaneous presence of a number of control signals PTT of multiple workstations 11, 12, 13, the control units 31, 32, 33 select the voice signals of one of the workstations 11, 12, 13 according to predetermined or predeterminable criteria. Alternatively, there is the possibility that the speech signals of the individual workstations 11, 12, 13 are superimposed according to predetermined criteria. The thus selected or superimposed speech signal is transmitted to the radio transmitter 51, 52, 53, and transmitted by this radio transmitter. In order to forward the speech signals arriving at the respective radio receiving system 61, 62, 63, the control units transmit the speech signals transmitted to them to the workstations 11, 12, 13 connected to them, a received signal SQU and the received speech signals.
    In practice, a frequency service and also the additional services described in the later part of the text consist of at least one software component in which the control and communication functions of the frequency service are implemented and at least one software component in which the Processing and distribution of the audio signals together with the signaling information PTT and SQL) are realized. These software components can be executed together in a PC server or in a special hardware component. However, it is just as possible to execute these software components on different PC servers, in different virtual machines or on special hardware components or, for example, to operate the software component of the audio transmission and distribution multiple times in order to provide redundant transmission of the To be able to realize audio signals.
    The realization of the transmission of voice and signaling information takes place increasingly via aviation-specific data distribution networks, whereby the pilot workstations of the frequency services that are connected to the radio devices can be spatially separated over greater distances. The transmission of the voice and signaling information between the workstations 11, 12, 13 and the control units 31, 32, 33 via WANs wide area networks and the individual radio devices are often connected via lines with low bandwidth to the control unit.
    With the first embodiment of the invention, speech signals can be transmitted without blocking. In the first embodiment of the invention, if a workstation 11, 12, 13 wants to send voice signals to a plurality of frequency services 31, 32, 33, then each frequency service selected from this workstation 11, 12, 13 will be selected , the same voice signal transmitted. Overall, thereby the same voice signal is transmitted multiple times in the data network. On the other hand, if a frequency service is monitored by several workstations 11, 12, 13, this will be transmitted to each workstation 11, 12, 13 the same voice signal. Thus, this voice signal is also transmitted multiple times in the network.
    In Fig. 3, a second embodiment of the invention is shown in more detail. This shows a communication system for voice communication by means of a number of workplaces 11, 12, 13 for air traffic controllers. The communication system comprises a number of radio transmitters 51, 52, 53 and radio receive devices 61, 62, 63. As in the first embodiment of the invention, each of the workstations 11, 12, 13 respectively has at least: at least one voice input unit 111, 121, 131 , in particular a microphone, - at least one voice output unit 112, 122, 132, in particular one
    According to a computer, at least one operating unit 113, 123, 133 for generating an operating signal PTT, indicating that from the respective workstation 11, 12, 13 by means of the voice input unit 111, 121, 131 voice signals to one of the
    Radio transmitter devices 51, 52, 53, at least one display unit 114, 124, 134 for displaying a reception signal SQU, which indicates whether voice signals are output at the voice output unit 112, 122, 132 from one of the radio reception devices 61, 62, 63; and - at least one selection unit for selecting the radio transmitter devices 51, 52, 53 and radio receiver devices 61, 62, 63, with which the workstations establish a voice connection on the basis of control signals.
    The workstations 11, 12, 13 transmit the speech signals produced by the speech input units 111, 121, 131 and the control signals PTT generated by the control units 113, 123, 133 to the distribution units 21, 22, 23 which transmit the speech signals to the radio transmitters 51, 52 , 53 forward. These give the transmitted from a workstation 11, 12, 13 speech signals while transmitting a
    Control signal PTT off. The radio receiving devices 61, 62, 63 receive voice signals by radio. The voice signals received by the radio receiving devices 61, 62, 63 are supplied to the individual distribution units 21, 22, 23, which forward the voice signals to the workstations 11, 12, 13. The voice signals are output from the workstations 11, 12, 13 on the respective voice output units 112, 122, 132. During the reception of speech signals and their forwarding, the radio receiving devices 61, 62, 63 each transmit a received signal SQU via the distribution units 21, 22, 23 to the workstations 11, 12, 13.
    The communication system also has a number of distribution units 21, 22, 23, which are each assigned to a workstation 11, 12, 13, wherein each workstation 11, 12, 13 at least one, in the present case exactly one, distribution unit 21, 22, 23 assigned. Between each of the distribution units 21, 22, 23 and the workstation 11, 12, 13 associated with this distribution unit 21, 22, there is a logical or physical data connection with a predetermined bandwidth, with the voice signals from each voice input unit 111, 121, 131 and voice signals to each voice output unit 112, 122, 132 of the workstation 11, 12, 13 as well as control signals PTT and receive signals SQU are transferable.
    The distribution unit 21, 22, 23 conferred or superimposed on it by
    Radio receiving devices 61, 62, 63 incoming voice signals according to a predetermined rule based on control signals. The speech signals determined therefrom are transmitted to the workstation 11, 12, 13. In the event that speech signals are present at all, they forward a received signal SQU to the workstation 11, 12, 13. The respective distribution unit 21, 22, 23 transmits to it from the workstation 11, 12, 13 transmitted speech signals to previously selected by means of control signals radio transmitting devices 51,52, 53rd
    In the second embodiment of the invention, for the transmission of voice signals from the workstations to the distribution units, the required bandwidth is constant and independent of the number of frequencies being discussed and intercepted.
    With the third embodiment of the invention described below, illustrated in FIG. 4, the disadvantages of an inefficient utilization of the bandwidth available in the network as well as the disadvantage of a non-deterministic bandwidth requirement of the individual components are to be avoided. The third embodiment of the invention is illustrated on the basis of the first embodiment of the invention and essentially has the features of the first two embodiments of the invention. - Same speech signals should be transmitted over the network only once more, which leads to a more efficient use of the available bandwidth or avoids unnecessary oversizing of the network. - From the point of view of the individual components workstations 11, 12, 13, control unit 31, 32, 33, their bandwidth requirement when accessing the network is limited to the top and for each workstation 11, 12, 13 of the number of control units 31, 32, 33, which simultaneously listens for and / or discusses a workstation 11, 12, 13, or for each control unit 31, 32, 33, independently of the number of workstations which simultaneously listen to it. In addition to the communication structure shown in FIG. 2, an additional workstation service is implemented for each workstation 11, 12, 13 to improve the system architecture, which is implemented in a distribution unit 21, 22, 23. This results in a structure in which the workstations 11, 12, 13 can be arranged away from the control units 31, 32, 33 over any desired distances over a wide area network WAN.
    The workstation service running on the distribution unit 21, 22, 23 realizes all radio functions of a workstation 11, 12, 13 and permits the remote connection of the operating devices and the audio input / output units. On the one hand it transmits the voice signals of a workstation 11, 12, 13 to all control units 31, 32, 33 or frequency services used and on the other hand it receives all voice signals from the control units 31, 32, 33 or frequency services and forwards them to the Workplace 11, 12, 13 further, these voice signals according to their allocation to audio output units of the workstation 11, 12, 13, such as Headphones, speakers, ..., to be conferred.
    In this case, it is possible for the possible nr.n communication relationships between the workstation services in the distribution unit 21, 22, 23 and the frequency services in the control units 31, 32, 33 to be implemented in the local network 81 of a data center 8. Compared to a wide area network Fig. 2, in a local network 81, bandwidth demand plays a minor role in the cost and sizing of the network components. Similarly, in a local area network, 81 different distribution mechanisms, e.g. Realize multicast groups more easily.
    Each workstation 11, 12, 13 is thus connected via a wide area network to a workstation service or a distribution unit 21, 22, 23, whereby the necessary bandwidth is low and deterministic, no signals need to be transmitted multiple times and during operation even with a change in the frequency services used by the workstation 11, 12, 13 no additional voice signals need to be transmitted. Thus, a strict logical 1: 1 exists between the workstation and the workstation service or the distribution unit 21, 22, 23
    Communication relationship, whereby the data rate required per workstation 11, 12, 13 in the wide area network is minimized, deterministic and also limited.
    The frequency service implemented in the control unit 31, 32, 33 is used for the
    Setup and monitoring of the audio connections to the frequency-service-allocated radio transmitter and radio receiver operating with overlapping chains or CLIMAX operation used, each frequency service manages a predetermined radio frequency.
    There is a logical 1: 1 communication relationship between the frequency service and the radio transmitters and radio receivers, whereby the necessary bandwidth between the frequency service and the radio devices is limited and deterministic, regardless of how many workstations 11, 12, 13 have a frequency Actually use distribution unit 31, 32, 33. Thus, the necessary bandwidth between the radio devices and the frequency service is minimized, whereby an audio compression of the speech signals for bandwidth reduction on this transmission link is not absolutely necessary.
    So that a frequency service or a control unit 31, 32, 33 several radio receiving devices 61, 62, 63 are assigned and each user can select a specific location or in the case of operation with Best Signal Selection the selection of the frequency service of Each user can be individually overruled, the voice signals of all radio receiving devices 62a, 62 of a control unit 31, 32, 33 are transmitted to the distribution unit 21, 22, 23 in order to perform the appropriate selection there. The evaluation of the quality of the received signals takes place in the control unit 31, 32, 33, this information is transmitted to the respective distribution units 21, 22, 23 and the actual selection of the speech signal to be sent to the workstation takes place only through the workstation service in the distribution unit. This makes it possible to realize a system-wide uniform evaluation and ranking of the received speech signals and still give each operator the ability to make an individual selection of the speech signals of each frequency service.
    In a fourth embodiment of the invention, a plurality of radio communication systems can be interconnected to virtual centers. 5 shows by way of example the communication structures of such a communication system, wherein in the individual data centers 8a, 8b are connected via higher-level control units 41, 42, 43 to the radio devices.
    The individual control units 31a-33a, 31b-33b arranged in the computer centers 8a, 8b have a reduced functionality compared to the frequency services of the previous embodiment of the invention. They arbitrate in the transmission direction, the voice signals from the workstation services of a computer center 8a, 8b for a higher-level control unit 41,42, 43 and distributed on the other hand in the receive direction, the voice signals of the control unit to the workstation services of the distribution unit 21, 22, 23 of a data center 8a, 8b, eg for all users who want to listen to this frequency. For each frequency, exactly one control unit 31a-33a, 31b-33b is available in a data center. A higher-level control unit 41, 42, 43, which can be operated geographically at a location other than a data center, operates the control units 31a-33a, 31b-33b from different data centers 8a, 8b, whereby on the connection between a control unit 31a-33a, 31b-33b and a higher-level control unit, no voice signals are transmitted multiple times and thus the bandwidth required over the WAN is static and deterministic. In addition, an active connection between a control unit 31a-33a, 31b-33b and a higher-level control unit 41, 42, 43 in a data center 8a, 8b is only necessary if in this data center 8a, 8b at least one workstation 11, 12, 13 this Frequency has keyed. For the realization of a virtual center, it is not absolutely necessary that the workstations 11-16 always connect to the same data center 8a, 8b. For example, structures may be realized that enable the following operational cases: In the event of a failure of a data center 8a, 8b, workstations 11-16 and higher level control units 41, 42, 43 connect to a backup data center to maintain operation ,
    In the case of small airports, it may be useful, for example, to take over operations from other workplaces at a larger workstation during the night hours.
    At very small airports, it may be useful, for example, not to form the data centers with the distribution units, and to let the workstations 11-16 communicate directly with the higher-level control units 41, 42, 43.
    In the first, third and fourth embodiments of the invention, it is possible to realize a coupling between two or more frequencies. By way of example, an extension is shown with reference to the third embodiment of the invention in Fig. 6, in which frequencies are coupled together. For this purpose are in the
    Data center 8 additional coupling services 7 realized. When an operator wants to couple two or more frequencies managed by control units 31, 32, 33, respectively, this coupling is assigned to a coupling service 7 which receives the signals received from a frequency service or control unit 31, 32, 33 to which other selected control units - one also speaks of a coupling group - forwards the signal on all selected frequencies. The advantage of this solution is that, in contrast to a coupling directly at the workplace, the delay times are reduced in the coupling loop, since the voice signals do not need to be transmitted twice over the wide area network.
    Another advantage of this solution is the central management of a coupling group, whereby couplings of the same frequencies by several users, once centrally controlled in the coupling service 7 and not distributed in the participating workstations 11, 12, 13 and control units. This can avoid runtime effects and mutual blockages.
