Abstract

An information system in which a central transmission device communicates data in addition to messages contains additional relevant information, which has a locational and/or user-specific relevance to the message and in which each communication device initially evaluates the additional information as to whether the messages for the respective communication device are relevant, and depending on this verification, processes the messages or passes them on. An independent claim is included for a method for transmitting messages to a number of communication devices.

Description

  • The The present invention relates to an information system, in particular a warning system for transmission of messages from a central transmitting device to a Variety of communication devices, the messaging preferably with the help of a satellite. In addition, the present concerns Invention a method for preferably satellite-based transmission from messages to communication devices.
  • The Development of information or warning systems has due to the lately more often natural catastrophes increasingly gaining importance. It has been found that the problem with the occurrence of natural disasters was not primarily that the Dangers would not have been recognized. Rather would have The number of victims can be significantly reduced if the opportunity would have existed persons threatened by the danger as extensively and early as possible to inform.
  • systems to warn people of impending dangers are accordingly preferably interpreted in such a way that a large number of people at the same time can be informed. For this offers Accordingly, the use of satellites as transmitting devices because even with a small number of satellites a global Cover can be achieved and accordingly many people can be informed at the same time. However, existing mobile networks still do not offer the possibility, coverage To disseminate information.
  • On one side would be thus the use of satellites for the transmission of information or Warnings are desirable on the other hand, the problem then is that possibly also persons who receive information or warnings for which they Information is not relevant as it is from the upcoming For example, risk is not affected at all. In the case however, that people have been constantly warning for a long time have received that for they are of no importance, there is a risk that ultimately one actually relevant warning message is disregarded.
  • Of the The present invention is accordingly based on the object to indicate a possibility as targeted as possible within a global warning system To address persons who are actually affected by an imminent danger are.
  • The We abandon the task specified in the independent claims Invention solved. Advantageous developments of the invention are the subject of the dependent claims.
  • core idea The present invention is to provide means by which in a sense a pre-filtering of the warning information can be done so that the Users of the communication devices Finally, only those information displayed or disposal be put for this are also relevant with high probability.
  • Accordingly, according to the invention Information system for transmission of messages from a central transmitting device, in particular a satellite, proposed to a variety of communication devices, wherein data transmitted by the central transmitting device in addition to the actual message contain additional information, which has a local and / or user-specific relevance of messages, and wherein each communication device first checks the evaluation of the additional information, if the News for the respective communication device are relevant and dependent from this review the Processes or reproduces messages.
  • Also according to the invention a communication device proposed for use in an appropriate information system, which receiving means for receiving data comprises the messages as well as additional information, which has a local and / or user-specific relevance give the news information. Furthermore, the communication device has evaluation means, for testing based on the additional information, whether the messages are relevant for the communication device or not, as well as processing means for processing or reproducing the messages depending on the result of the check the evaluation on.
  • The solution according to the invention allows due to the possibility of prefiltering or pre-checking the incoming messages in particular the use of satellites as transmitting devices, since of the many receivers that can actually receive the satellite signal, ultimately only those devices play the news, which automatically The review concluded that the information is relevant to the user. This provides a very effective system for communicating warning information which ensures that only those who are actually affected are warned in a timely and timely manner.
  • The Additional information can in particular define a geographical area for which the Messages are relevant. For example, the geographical area can be are defined by multiple locations that include the area. For this offers It is these places, for example, by a reference position and specify a plurality of relative positions, in particular the Accuracy of position information for the different positions can be different. Usually is here provided that the reference position with a higher accuracy is given as the relative positions, reducing the amount of to be transmitted Data for the indication of the area affected by a warning message relatively low Measure reduced can be.
  • The Deciding if a communication device is within an affected one Can then be made on the basis of supplementary data, the device to disposal be put. This could be it may be, for example, navigation data, which with the help a communication device assigned or in this integrated navigation receiver can be determined. Also, the manual specification of the current location by a user of the communication device would be possible. After all would be too a (rough) localization about the cell information of a mobile network conceivable.
  • in the Regard to the consideration the user-specific information can also be predetermined, that is manually set by a user of the device, which types of warning information the device will respond to in an appropriate manner should. For example, you can different categories of use cases are defined, where then determined according to a corresponding scheme in which make an information is reproduced or not.
  • A Another advantageous embodiment of the invention relates to measures which ensure that also inside of closed buildings devices the information can still receive. For example, if a satellite is used as a central transmitting device, that's usually enough used transmit power usually for receiving the signals within of closed buildings not from. The reason is in that the signals are usually exclusively through reflections in the environment located objects to the receiver and accordingly the final incoming signals for a clear evaluation too weak.
  • Around To overcome this problem is, according to the advantageous development the invention provides that the from the satellite to the or communicated the communication equipment Data includes the text information - ie, for example, the warning message - including Information share and a co-ordination share, which Coordination portion of the communication device for synchronization to the Satellite is used. The text information containing Data is then transmitted by the satellite at least twice, the communication device the while multiple transfers received information shares in-phase summed and from the In this case formed sum signal determines the text information. By the repeated transmission information and that made possible by means of the co-ordination component In-phase aggregation of the information shares can then ultimately be formed a sum signal which is strong enough for a unique and error-free evaluation of the information is. Also the reception the information within closed buildings is made possible in this way. It is not even the regular or periodic repeating the data transmission required, since the co-ordination component can also be used to - preferably subsequent Uniquely identify textual information. The application possibility In the context of a global warning system, this makes it clear elevated, as well as very simple devices used as a receiver can be not necessarily connected to a receiving device outside of buildings have to be.
  • In summary Thus, the present invention is an information system for providing messages, in particular warning information to disposal which ensures that even only those Users of terminals about upcoming Dangers are informed that are actually affected. The effectiveness such a system is significantly increased in this way.
  • following the invention will be explained in more detail with reference to the accompanying drawings. Show it:
  • 1 schematically the components of an information or warning system according to the invention;
  • 2 the structure of a global warning message;
  • 3 the procedure for defining an area for which a submitted alert message is relevant; and
  • 4 a diagram illustrating the procedure for receiving information within a closed building.
  • 1 shows first schematically the components of a generally with the reference numeral 1 provided communication system according to the invention, which can be used in particular for the realization of a global emergency call / warning system.
  • The central office of the emergency call / warning system 1 is as shown by a central facility 10 , For example, formed a telephone control center, which receives incoming emergency calls from participants in the system, evaluates and - if necessary - initiates appropriate assistance. In the case of accident of a participant can by the central office 10 For example, an ambulance or a rescue helicopter to be informed and ordered to the accident site. Another task of the headquarters 10 It also consists in confirming incoming emergency calls and transmitting corresponding answers. Finally, the central office 10 also be used as a control center of a warning system and in the event of imminent danger information to the participants of the system 1 send.
  • Schematically represented in 1 are three participants of the communication system according to the invention which may be very different in terms of their design and positioning. A first participant 20 is formed, for example, by a vehicle, wherein the communication device arranged in the vehicle is configured to request assistance in the event of an accident and, for example, the triggering of an airbag. This can be initiated manually by the user of the vehicle, but it would certainly be conceivable that the communication device automatically sends an emergency call in the event of a major accident.
  • A second participant 21 is formed by a portable communication device, which may be formed in particular by a mobile phone. This phone 21 has accordingly in addition to the normal possibilities for mobile phone telephony extensions, which allow the transmission of an emergency call or receiving a corresponding response or a warning message.
  • A third participant is exemplified by an electrical appliance, for example. A TV 22 , educated. A special feature of this third participant is that the TV 22 inside a building 23 is arranged, which has an impact on the possibilities for data communication, which will be explained later. The stationary used device 22 In this case, therefore, can only be used for receiving warning information by the system 1 be provided, but not for the transmission of emergency calls.
  • It should be noted that the terminals of the system according to the invention 1 can be configured very diverse and can have a variety of functions. Also the use within the system according to the invention 1 can be done in different ways. Thus, as already explained, provision may be made for certain devices to be used exclusively for receiving warning messages by the system 1 On the other hand, other devices can both transmit emergency calls (possibly automatically under certain conditions) and also receive warning information in addition. Also within the framework of the system complementary from the various participants 20 . 21 and 22 used information may be of different types depending on the design of the devices.
  • For the communication between the different participants 20 . 21 and 22 and the central office 10 become satellites as connecting elements 30 . 30-1 . 30-2 used, over which the data connection is established. The connection to the central office 10 is hereby using a transmitting / receiving station 11 allows, which in connection with the central office 10 stands. The arrangement of the satellites and their number is preferably chosen such that worldwide a connection establishment between the participants 20 . 21 . 22 and one of the satellites 30 is possible, preferably at least three satellites 30 within the transmission and reception range of a communication device 20 . 21 . 22 should be available to allow alternative connections in the event of a data link failure.
  • The between the various components of the system according to the invention 1 exchanged signals can be distinguished according to their use within the emergency / warning system. A first function of the system 1 As already mentioned, the delivery of an emergency call by the subscribers and the corresponding answering of this emergency call by the central office 10 The communication connections that arise in this case can be distinguished as follows in the direction of the transmitted data and according to the various components between which there is a communication connection.
  • Thus, initially two so-called. Forward connections are provided, which for the transmission of information from the control center 10 to the receivers gladly 20 and 21 be used. These forward connections are further distinguished according to whether they are in the direction of the satellite 30 directed or lead away from this. Accordingly, a transmission of information from the center takes place 10 or the transmitting / receiving station 11 So via a so-called. Forward Uplink I U to the satellite 30 and via a forward downlink I D from the satellite 30 to the communication devices 20 . 21 , The transmission of information from the terminals 20 . 21 to the central office 10 in contrast, via so-called. Reverse connections, more precisely via a reverse uplink II U of the devices 20 . 21 to the satellite 30 and a reverse downlink II D from the satellite 30 to the transmitting / receiving station 11 the central office 10 , The various procedures for data transmission, in particular in the context of the reverse uplink II U and the forward downlink I D will be explained in detail later, the communication between the satellite 30 and the transceiver station 11 in contrast, can be done in the context of conventional methods, which are not the subject of the present invention.
  • Further communication links which are set up within the framework of the emergency call / warning system according to the invention serve in accordance with the second function of the system 1 to submit warning information. In this case, only one communication is in the direction of the central office 10 to the terminals 21 and 22 provided, it is thus turn (in the usual way built) Forward Uplink III U to the satellite 30 and a forward downlink III D from the satellite 30 to the terminals 21 . 22 educated. Also, the specific measures for forming the forward downlink III D for the transmission of warning information will be explained in detail later.
  • The frequency ranges used for setting up the various communication connections can, in principle, be selected in the desired manner, taking account of regulatory provisions. However, as already explained at the beginning, the terminals should as far as possible be based on technologies already in use. Accordingly, it has proved advantageous for the forward downlink frequencies in the so-called L-band in the range between 1.6455 and 1.6465 GHz and for the reverse uplink frequencies in turn in the L-band in the range between 1.544 and 1.545 GHz use. The advantage of this choice lies in the fact that these frequency ranges are close to the frequencies used by already existing mobile radio networks and, moreover, also include the frequency ranges used in the context of navigation systems. Transmitting and receiving means for the use of such frequencies are thus already in use many times and can accordingly also for devices within the scope of the system according to the invention 1 be used. For the forward uplink, frequencies in the so-called Ku band between 14 and 14.25 GHz and for the reverse downlink frequencies in the X band in the range between 10.7 and 11.7 GHz are preferably used. The distribution of the choice of these frequencies is that the antennas used for this purpose can be made geometrically small. Again, however, it should be noted that other frequencies could be used for the different signal paths.
  • An essential function of in 1 illustrated emergency / warning system according to the invention is thus to warn participants of the system from imminent dangers. For example, people should be warned of impending earthquakes or tidal waves. Even severe weather warnings for affected areas would be a conceivable application for such a warning system.
  • in the Difference to the data transmission in the context of an emergency call is not the task, a participant individually, but preferably all participants at the same time to warn, who are affected by an imminent danger. So it has to be within a possible short period possible many devices be addressed, but ultimately the warning information, however should only be forwarded to such users, by the possibly upcoming event are affected.
  • A first inventive aspect of this warning function of the system 1 is therefore, together with the transmission of the text message that informs about the upcoming event, also determine for which geographical area the information is relevant. Preferably, as shown in FIG 3 defines the local relevance for the message or geographical area concerned by several single sites or locations that together delimit the affected area. As shown in 3 Accordingly, seven different points are selected, which in the case shown, a lake area 60 which is affected by a storm warning that is the actual subject of the alert.
  • The delimitation of the affected area 60 depends on how many places, which the area 60 should be available. Of course, a larger number of locations leads to an increased amount of data, so in this case, a compromise must be found to define the actual area in a data packet as compressed as possible.
  • According to a particularly advantageous Training is provided accordingly, the area 60 on the one hand by a reference position 61 to define whose location is specified very precisely, and on the other hand, the other points as relative positions 62-1 to 62-6 whose position relative to the reference position is specified. In the illustrated example, for example, could be provided, the reference position 61 with the help of a total of 50 bits specify, in which case for the length and width of the reference position 61 each 25 bits can be used, which ultimately allows a position specification with an accuracy of 1.2 meters. The relative positions, on the other hand, could be specified with 32 bit accuracy (16 bits for the length and 16 bits for the width), with increments of 91 meters each. As a result, a total of 6,000 km in length and width can be defined, which is sufficient for all imaginable scenarios.
  • Again, it should be noted that the different value ranges for the indication of the individual positions could also have been chosen differently to the affected area 60 set. For example. It would also be conceivable to make the accuracy dependent on the maximum size of the area.
  • For the warning message then a data format can be selected, as for example in 2 is shown. The entire data package 43 consists of four different blocks, with a first block (for example, with a length of 1,600 bits) is used as a so-called coordination or preamble, which serves to enable synchronization of the receiving devices to the satellite signal. It is noteworthy that the preamble in the illustrated embodiment is very long, which is used in accordance with the later explanations to allow reception of the satellite signals in closed rooms or buildings.
  • The two other blocks 43-2 and 43-3 serve the local relevance of the in the subsequent block 43-4 to define the so-called message containing information, the block 43-2 to indicate the previously explained reference position 61 while the block 43-3 the relative positions 62-1 to 62-6 indicates.
  • A peculiarity of in 2 As already mentioned, the data format for the warning message consists of a very long preamble 43-1 is selected. The reason for this is that as part of the warning function of the communication system according to the invention 1 the warning message should not only be sent to receivers located outdoors, but in particular also devices should be addressed which are located within closed buildings and used in a stationary manner. However, as the presentation in 1 can be removed is for such devices 22 usually a direct reception of the satellite signal is not possible. Instead, only signal portions are received, which are located in the environment objects, such as trees 24 be reflected. This here on the device 22 Consequently, the incoming signal is significantly weakened.
  • Due to the particularly or disproportionately long preamble of the warning message is now first ensured that even at a very weak at the receiver 22 incoming signal synchronization of the receiver to the satellite signal is enabled. However, this measure alone would not yet be sufficient for a suitable reception of the actual warning information, since the information component of the signal is ultimately too noisy in order to be able to evaluate and use the information without any doubt. As part of an advantageous development of the system according to the invention, a special method for data transmission is accordingly used, which is schematically in 4 is shown.
  • The basic idea of this special transmission method consists in the fact that the warning messages are transmitted more frequently and are summed up by the receivers in the correct phase until the resulting summation signal permits an error-free evaluation of the information. For example, according to the illustrated example, a certain warning information MSG A is sent five times, the corresponding information portions 70-2 to 73-2 and 75-2 from the receiving means of the communication device to the sum signal 76 be summed up. It is important here that the summation of the information components takes place in the correct phase, for which purpose the respective previous transmission of the preambles or the coordination components 70-1 to 73-1 and 75-1 is being used. Only by previously exactly synchronizing the receiver to the satellite signal using the preambles is a phase-correct summation of the information components possible, so that the desired amplification of the sum signal 76 is achieved.
  • Another special feature of the method is that it is not absolutely necessary that the corresponding message is repeated periodically. Instead - as in 4 shown - in the meantime, another message MSG B is transmitted, which contains information about another event and possibly for participants of the communication system 1 is determined in another geographical area. To ensure that the information share 74-2 not ver must be added to the information portions of the first message MSG A, it must therefore be ensured that the receiver acquires knowledge of which message is currently being transmitted. For this purpose, in turn, the co-ordination component or the preamble preceded by the information portion with the message can be used. The preamble additionally contains information about which the message can be identified. Although this information does not provide information about the content of the message, but allows an identification of the same, so that it is ensured that only those pieces of information are assigned, which are associated with a common message. Ultimately, therefore, the preamble in addition to the required for the synchronization of the receiver phase estimation also fulfills the task of marking the messages in order to allow the formation of a unique sum signal in the sense of the inventive method.
  • The in-phase amplification of the information components achieved in this way ultimately leads to the fact that the sum signal formed 76 can be uniquely evaluated to further process the message. In this way it is also ensured that even within buildings located receivers can exploit the satellite signal after a repeated repetition of the transmission of the message. As a result, the desired effect is sought that a warning information can be transmitted simultaneously as many or exactly the affected persons.
  • It should be noted is that the just described procedure does not affect the reception limited by satellite signals is, but in principle then can be used when textual information by means of a relatively weak at a receiver received incoming signal should be. Even with other transmission methods can then by an in-phase addition of the information parts transmitted several times a suitable reinforcement of the signal until an evaluation of the same is possible.
  • By the warning function of the emergency call / warning system according to the invention can So at the same time a large number of affected participants with Warning messages are supplied. By the addition of Information regarding the local Relevance of the warning information is further ensured that the Participants can also notice whether they are affected by this message or not. According to one particularly preferred embodiment is even provided that provided in the receiving devices evaluation independently evaluate the information regarding local relevance and on the basis of supplementary Check information, whether the message for the recipient due to its current position is currently relevant or not. Only after checking this Relevance then decides the device itself, whether it's the news further processed by means of suitable processing or reproducing means and, for example, reproduces optically or acoustically or not. It exists thus not the problem that a user of the device a Receives a variety of warning information and then independently determine each time must, whether the message for it matters or not.
  • These advantageous prefiltering or automatic evaluation of the local In particular, relevance of messages may be based on navigation information done to the receiver for example, again about the satellite available be put. However, that would be it is also conceivable to otherwise determine the current position of the recipient without the receipt of additional Navigation signals to be instructed. If, for example, a mobile telephone is used as the receiving device, so could the rough position determination for the recipient also over the cell ID of the telephone network done. Also the manual input of the current position by the user and storing this Information in a corresponding memory of the receiving device would be conceivable.
  • Next the indication of the local Relevance of the warning information could a further clarification with regard to the user of the system or the arrangement of the receiving device in certain Facilities are made. For example, the information about one Storm warning for a receiver installed on a ship certainly relevant, while they are for one less users within a closed building is of interest. By inserting an additional Data blocks could for example, different user categories are specified, where then in addition Based on this information, the device automatically determines whether the information should be reproduced or not. In this Case could turn a manual input by the user specify which messages are of interest or not. This will be a very comfortable option for individual warning against the user of a device relevant dangers.
  • It can be seen from the above explanations of the various functions of the system according to the invention that the terminals via which a communication with the satellite or the center of the emergency call / warning system takes place can be designed in the most varied manner and can also offer different functionalities. The devices can be divided into different categories in terms of their uses the.
  • At the first place are such devices, both the transmission of text messages for delivering an emergency call as well as the reception enable global warning messages. Usually show these devices additionally also a navigation receiver to be used in the various transmission methods on the required Resort to navigation information to be able to. These equipment the first category for example be formed by portable communication devices. It would be though also conceivable, such devices to install in vehicles such as airplanes, ships or cars. In particular, in the arrangement of such devices in vehicles could beyond also be provided that the delivery of an emergency call automatically in the event of an accident or the like is initiated. Of course it is in this case the arrangement of the communication device to a Spot beneficial to accidents preferably little is affected. In the arrangement in a vehicle, for example, the assembly would be inside the passenger compartment - in particular on the dashboard - useful, because in this area the greatest security from unwanted damage consists.
  • A second category of devices form those, in turn, in moving objects - such. Vehicles - arranged or designed as portable communication devices. In contrast to the devices the previously described category, which includes the transmission enable text messaging and accordingly to the realization of a faultless data transmission Navigation information regarding the subscriber and the satellite consider have to, are the devices the second category exclusively intended to receive global warning messages. In this Case the use of a navigation receiver is not mandatory, because of the measures described above with regard to transmission the warning messages the complementary use navigation information is not mandatory. In spite of everything would even in these cases the navigation receiver additional benefits entail. For one thing the over him information is used as auxiliary information, the reception behavior of the device optimally tuned to the satellite signal. Furthermore offers the navigation receiver also the possibility automatically check the Relevance of the warning information with regard to a local restriction to check. These second option would, however also - as already portrayed - by the use of other information such as the location via cell identification a mobile network or by the previous manual input by a user of the device consist.
  • A third category possible Terminals finally exists in quasi-stationary Devices, which are arranged in particular within closed buildings. such equipment can for example, by electrical appliances like televisions or radios. They are exclusive trained to receive the global warning information of the system, due to the previously described measures receiving the information despite the arrangement of the devices inside closed buildings possible is. The use of an additional navigation receiver is not useful in this case. To an automatic pre-sorting of warning information in terms of local relevance to be able to is in such devices preferably provided that appropriate information through a user when installing the device.
  • It should be noted is further that the present invention with regard to the transmission supplementary Information on the relevance of messages not on the transmission limited by satellite is. Also in the message medium terrestrial transmitter for the radio or television company would be a corresponding coding conceivable. Furthermore, the inventive method could also with the message transmission be used by telephone or mobile. Basically it would be the advantage is that only those persons receive the message get, for which ones actually is relevant.
  • All in all Thus, the present invention provides a satellite-based communication system to disposal provided, which is a reliable transmission text information or messages in combination with local or user-specific information. This now exists the possibility, to form an effective global emergency call / alert system.
