- Further areas of application of the invention are operational control centers of public transport companies, energy suppliers or air traffic control.
- the term "operations control center” is to be understood in its broadest meaning. It includes not only operations control centers for handling emergency calls or unusual situations, but generally all departments in which the work of several people who have radio contact with the operations control center is coordinated. For example, an air traffic control center or a coordination office of a public transport company an operational control center in the sense used here. More particularly, the invention relates to the processing of radio calls in an operations control center.
- a control center according to the prior art has in a typical configuration about five workstations, about five to nine radio devices and a central switching center. At each workstation, you can
- the known control center also has a multitrack tape device or a hard disk in order to record all radio traffic for documentation.
- the radio device system, the radio signaling system and the documentation system are three essentially separate assemblies. This complicates operation in several ways. First, the mixing ratio of the individual radio channels must be at each workstation can be set manually. This represents a considerable effort. Second, when a radio call is sent, the operator at the workplace must manually determine the transmission channel. This also binds the operator's attention. Third, locating a particular radio message on the multi-track tape device is very tedious, so that the operator usually has to rely on his memory.
- the object of the invention is to create a method for processing radio calls in an operational control center and an operational control center with increased user-friendliness.

- the technical foundations for solving this problem are created by a method having the features of claim 1 and an operational control center having the features of claim 16.
- the dependent claims define preferred embodiments of the invention.
- the enumeration order of the steps in the procedural claims should not be understood as a restriction of the scope. Rather, the method claims are also intended to include configurations in which these steps are carried out in a different order or in whole or in part in parallel or in whole or in part interlocking.
- the invention is based on the basic idea of using digital and computer technology to create expanded possibilities in the processing of radio speech signals.
- a digital radio speech signal is processed in a computer-assisted manner, depending on a transmitter identifier and / or a transmitter status information and / or a transmitter location information and / or the channel information.
- the sender identification and / or the sender status information and / or the sender location information and / or the channel information relate to a radio call that is received or received by the control center.
- the technical foundations are created in order to provide a significantly increased ease of use at the workplaces of the operations center.
- the operators are out of routine tasks relieves and can concentrate fully on the optimal organization of the operations. Even seemingly minor improvements are of great importance here, because in critical situations in particular, when the strain on the operators is particularly high, the potentially decisive freedom can be created.
- processing is to be understood in general to mean all the steps for transmitting, reproducing, influencing, storing and archiving the radio speech signal.
- this processing can also concern further signals and / or data.
- the generated digital radio call signal corresponds to the radio call that is just arriving or received at the operational control center, or is at least influenced by it.
- This radio speech signal is then processed as a function of at least one of the items of information mentioned.
- signals from a radio signaling system are preferably evaluated, which can be encoded as FSK-modulated signals or tone sequences. These can be, for example, transmitter identification signals (to identify the transmitting radio) and / or transmitter location signals (to transmit coordinates, which have been determined, for example, by a GPS device) and / or transmitter status signals (for example to transmit predefined status codes) ,
- At least one acoustic parameter is automatically set as a function of the transmitter identification and / or the transmitter location information and / or the transmitter status information (in particular information transmitted by a radio communication system) and / or the channel information.
- the acoustic parameter is preferably the volume or the sound impression or the apparent spatial arrangement of the signal source during playback.
- the signal reproduction can be designed in such a way that the user has a spatial impression of the signal source which corresponds approximately to the actual position of the transmitting radio within the area of use.
- calls can be made from certain Sources or with certain status information (e.g. emergency calls) can be played at increased volume.
- the setting of at least one acoustic parameter just described is particularly advantageous in embodiments in which a mixture of several signals to form the playback signal takes place.
- the relative volume of the several signals to one another can be changed as a function of the transmitter identifier. For example, it can be provided that all signals which are assigned to an insert selected by the user or to several inserts selected by the user or to all inserts supervised by the user are reproduced at a higher volume than signals which belong to other inserts.
- the radio speech signal is archived.
- An application-related logging preferably takes place here.
- a protocol with a plurality of entries is kept for each use, each entry corresponding to a relevant event (e.g. incoming call).
- the archived radio calls are accessed via references in the log entries.
- the archiving preferably also includes the radio calls sent by the control center and / or further information, for example
- the digital radio speech signal corresponds to a radio call to be sent by the control center or is at least influenced by it.
- An automatic channel selection of the radio call to be transmitted is preferably provided, depending on the channel on which the radio to be addressed sent the last time it received the radio message. With a single interaction (e.g. a mouse click on a control panel), the operator can then send a paging to the desired recipient without having to deal with channel selection.

More specifically, in a receive operating mode of the work station 32, the network interface 44 converts the incoming digital data packets P into the first radio speech signal X1, which is sent to the computer module 46. In contrast, in a transmission operating mode, the network interface 44 generates digital data packets P from the second radio speech signal X2, which packets are output to the local computer network 28.

- the radio 10 When the radio 10 receives a radio call during operation of the control center, this is signaled to the radio adapter 14 via the carrier detection signal CD.
- the actual radio call is output as an analog received signal AR, digitized by the analog / digital converter 16 to form the digital received signal DR and processed in the signal processing stage 24.
- the signal processing stage 24 evaluates all signals of a radio signaling system contained in the radio call (in particular transmitter identification signals, transmitter status signals and possibly also transmitter location signals). Furthermore, the signal processing stage 24 compresses the dynamic range of the received signal DR in order to improve its intelligibility. In alternative versions further signal processing steps are provided, for example active noise suppression.
- the radio adapter 14 in which the radio adapter 14 has only a single interface 12 for connecting a single radio device 10, no mixing processes take place in the signal processing stage 24.
- the radio adapter 14 can have a plurality of interfaces 12 for connecting one radio device 10 each (or an interface 12 for connecting a plurality of radio devices 10).
- the signal processing stage 24 can already mix the received signals from these multiple radio devices according to the requirements of the individual workplaces 32.
- the data packets P fed into the local computer network 28 by the radio adapter 14 (which correspond to the first radio speech signal X1) are available to all workplaces 32 of the operations control center.

- each work station is always provided with all radio speech signals fed into the local computer network 28. For example, if the operations control center has nine radios, nine radio adapters, and five workstations, each workstation has access to all radio speech signals that are fed into the local computer network 28 by these nine radio devices and radio adapters. 2 illustrates the user interface shown on the screen 36 of each work station 32.
- Each index card 70A, 70B has a tongue 72A, 72B, which contains a short identification of the respective application (eg type of application and location).

- the index card 70A has an identification field 74, a field 76 for the vehicle status display and a protocol field 78.
- the identification field 74 more precise information about the use is displayed.
- the identification field 74 contains the name and the telephone number of each caller transmitted by a telephone system or the module 62.
- field 76 a wagon status table is displayed which, for each motor vehicle involved in the operation, provides an identification of the vehicle, the time of delivery of the operation order to the driver, the start of the journey, the arrival time and the time at which the vehicle is released from the operation has been.
- the log field 78 shows a section of a continuous log with all events relevant to the use, each with the date, time and keyword.
- the possibilities provided by the digital signal processing are advantageously used. This is because the mixing ratio of the radio speech signals is automatically set as a function of information that is transmitted by the radio reporting system, for example the transmitter identification or the transmitter status information or the transmitter location information. As already explained above, this information is extracted from the radio signal from the signal processing stage 24 of the radio adapter 14 and transmitted as computer data to the work station 32 via the local computer network 28. In alternative embodiments, however, it is provided that the radio signal (usually FSK-modulated signals or tone sequences by which the information is encoded) is transmitted unchanged from the radio adapter 14 to the work station 32 and only there by the Evaluate signal processing stage 48 in order to obtain the information contained therein.
- the radio signal usually FSK-modulated signals or tone sequences by which the information is encoded
- the technique just described can be used to achieve automatic volume boosting of radio speech signals that determine
- Transmitters or certain groups of transmitters are assigned. Such a group of transmitters can be defined, for example, for every ongoing application.
- the transmitter device group of an insert is preferably determined by those transmitter devices that are located in the vehicles that are listed in field 76 of the index card 70A, 70B assigned to the insert.
- the workstation computer 34 When a radio call arrives from an emergency vehicle that is assigned to the index card 70A, 70B that is currently in the foreground, the workstation computer 34 recognizes this on the basis of the transmitter identification of the radio call. The corresponding radio speech signal is then reproduced to the operator at the work station 32 with increased volume, while other radio calls (which are not assigned to the application in the foreground) are only quietly recorded in the playback signal AP in the background or are suppressed entirely. Status signals that may have been transmitted can also be used to influence the playback volume; for example, emergency messages can be played louder than routine reports.
- the acoustic sense of location of the operator can also be used for further information transmission.
- radio calls from several emergency vehicles can be switched to different degrees on the right and left stereo channels in order to increase quick recognition by the operator and to avoid errors in the distinction.
- their radio messages can also be reproduced in such a way that they appear to be arranged in a virtual, two-dimensional grid for the acoustic-spatial sensation of the operator. Provision can furthermore be made to change the apparent spatial position of the signal source for the operator as a function of a transmitter location specification.
- the emergency vehicles are equipped with GPS devices and location information is transmitted in the form of radio message signals with every call, for example, a call from the eastern sector of a surveillance area can apparently be reproduced on the right for the operator, a call from the northern sector for the operator apparently in front, a paging from the western sector for the operator apparently on the left, and a paging from the southern sector apparently in the rear.
- a similar functionality can also be achieved by evaluating the transmitter identification if the approximate positions of the individual emergency vehicles are known.
- the operator wants to send a radio call at the work place 32, he performs a mouse click on the control panel 80, 82, 84 of the index card 70A located in the foreground, which identifies an emergency vehicle to which the radio call is directed , contains.
- the workstation computer 34 accesses a table in which each radio vehicle is assigned the radio channel on which it made its last radio message.
- the channel entered in this table is then used automatically either by addressing the radio set to this channel or (in embodiments which allow the radio to be automatically selected) a corresponding channel selection signal is generated.
- the transmission channel can optionally be displayed to the operator; however, it does not need to be set manually.
- the analog recording signal AM of the microphone 58 is converted in the analog / digital converter 52 into the digital recording signal DM, which in turn is processed by the signal processing stage 48.
- filtering processes and other measures to improve the signal quality and speech intelligibility can be carried out.
- Mixing operations are also possible, but in the present Embodiments are not provided in order to achieve a clear assignment of the transmitted signal to an operator.
- the signal processing stage 48 As an output signal, the signal processing stage 48 generates the second radio speech signal X2, which is transmitted from the network interface 44 as digital data packets P to the local computer network 28.
- the network interface 26 of the radio adapter 14 converts the digital data packets P back into the second radio speech signal X2, which (assuming an error-free transmission) is identical to the corresponding signal of the work station 32.
- the radio speech signal is output as a digital transmission signal DS to the digital / analog converter 18, and the transmission request signal SR is simultaneously set to an active level.
- the radio 10 now transmits the analog transmission signal AS received by the digital / analog converter 18 on the preset channel.
- the radio server 60 also shown in FIG. 1 is used for communication with other control centers. According to the previously known state of the art, radio messages that go beyond the own transmission range are transmitted by means of a complex and quality-reducing radio relay technology.
- the radio server 60 works similarly to a bridge and transmits data packets of the local computer network 28, which are intended for other operations control centers, to these other control centers.
- the radio server 60 is connected to a regional or national computer network (in the present exemplary embodiments to the state administration network), with which the other control centers designed according to the invention are also connected.
- the telephone accessibility of the operations control center can be ensured via a telephone system that is independent of the structure shown in FIG. 1.
- the functions of the telephone system are preferably controlled by the workstations 32 and / or the radio adapters 14 or other devices which are connected to the local computer network 28.
- CIT computer-integrated telephony
- extensive integration of the telephone functions into the processes described above is possible, even if additional lines for the telephone Speech signals are required.
- the module 62 for IP telephony provided in the exemplary embodiment shown in FIG. 1, on the other hand, enables complete integration of telephone and radio functions by also transmitting the voice signals of incoming and outgoing calls as digital data packets via the local computer network 28.
- the module 62 is connected to the telephone system or directly to telephone exchange lines.
- FIG. 3 illustrates that this log is stored in a log file 90A.
- the log file 90A has a plurality of entries, of which one entry is given the reference symbol 92A by way of example in FIG. 3. The same applies to the use assigned to the index card 70B (with log file 90B and entry 92B) and to all further uses (not shown in FIG. 3).
- Each entry 92A, 92B in a log file 90A, 90B has data fields 94, 96 and 98 for storing the date, the time and a keyword. Furthermore, each entry 92A, 92B contains a data field 100, which can contain a reference to an entry in an archive file 102 (represented by arrows in FIG. 3).
- the archive file 102 is managed centrally in the operations control center.
- an archiving device configured as a computer (not shown in FIG. 1) can be connected to the local computer network 28. In other configurations, archiving at the individual workplaces 32 is alternatively or additionally provided.
- the archive file 102 has a large number of entries, one of which is provided with the reference numeral 104 by way of example in FIG. 3.
- each entry 104 corresponds to an incoming or outgoing radio call from the control center.
- further information is archived in the archive file 102.
- the entries 104 in the archive file are arranged chronologically.
- Each entry 104 has four data fields 106, 108, 110 and 112, which form a continuous index worth, a time specification, an indication of the workplace 32 and the archived radio or telephone message.
- the radio or telephone message in the data field 112 can be encoded in a voice recording format known per se (for example mp3).
- the data field 112 in turn contains a reference which makes it easier to find the radio or telephone message in a further file or on a further recording medium.
- the operator in the exemplary embodiment described here only needs to double-click on the corresponding line in the protocol field 78 of an index card 70A, 70B.
- the workstation computer 34 then accesses the corresponding entry 92A, 92B of the log file 90A, 90B and takes the index value of the associated entry 104 in the archive file 102 from the data field 100 of this entry 92A, 92B.
- the workstation computer 34 accesses the entry via this index value 104 to.
- the radio or telephone message contained in the data field 112 is then reproduced via the headset 42. Overall, this application-related archiving considerably simplifies access to stored radio or telephone messages.
