Definitions

  • the invention relates to a method and a receiver for Reception of digitally coded messages by at least be broadcast on a transmitter and in a receiver be decoded using a location table.
  • RDS radio data system
  • Specifications of the radio data system for FM radio are among others in the publication Tech. 3244-E, March 1984 the European Broadcasting Union (EBU).
  • Radio receivers with suitable RDS decoders can transmitted data in addition to audio reception with the Record and decode the same receiver.
  • the receiver There is a in the receiver to decode the traffic reports Location table required, based on the one with the TMC message transmitted information, the affected place, the Extent or direction of an event in the receiver, can be decoded. These are for an area for which TMC messages should be decodable, for example a country the size of Germany, significant amounts of data required. Also step through Road network extensions or conversions or conversion of Traffic management changes. That's why they are Location tables with known recipients not in Read only memories (ROMs), but in exchangeable ones Storage, for example memory cards, chip cards, CD-ROMs, hard drives, hard drives. When decoding a single message is only a very small part of the Location table required. To reduce the The parts stored in the receiver could require memory a complete table of locations to be divided Example in different federal states. Longer trips would, however, have to be used when using such small memories Appropriate handling with the changeable memories to get prepared.
  • the object of the present invention is a method and propose a recipient who is less Storage capacity the decoding of digitally encoded Enable messages, but no special ones Operations by the user are required.
  • this object solved by checking whether the decoding required part of the location table stored in the receiver is that the decoding is correct and that not applicable if requested by the recipient a telecommunications network from a service computer required part of the location table sent by the recipient received, stored and for decoding the message is used.
  • the process according to the invention has the advantage that none complete storage of the respective location table in the Recipient is required. Thus, memories with smaller capacity, lower energy consumption and lower maintenance costs can be used. Besides, can in the service computer, every change and immediately Expansion of the road network should be considered so that always use the latest version of the for decoding in the receiver Location table is available.
  • the mission is one Identifier (number) provided with which of several Location tables the message is to be decoded. This will be at exploited the inventive method so that the Part of the location table is also requested when a corresponding part of the location table available in the receiver but this is a different identifier than the one received having. Because the identifier also the update status reproduces, thus outdated parts of the location table with overwritten new.
  • An advantageous embodiment of the invention The procedure is that when the Capacity limit one for the parts of the location table provided memory previously saved parts of the Location table overwritten according to specified criteria become. This ensures that the existing in the memory Parts of the location table largely to the expected TMC messages are adjusted. With this configuration it should be provided that the earliest saved Parts of the location table are overwritten or that a given criterion the geographic location of the overwriting parts of the place table. Besides, can this configuration should be further developed such that those parts of a location table are overwritten first that are not made by one in the recipient Area selection of the messages are recorded.
  • the inventive method can be provided that several Requirements that concern undecodable messages be bundled to the service computer.
  • the procedure is that one made in the recipient Area selection with the request to the service computer is transmitted. It is preferably provided that a request with an area selection of Service calculator in addition to that for each decoding message required parts of the parts Location table, which are covered by the area selection sends the recipient.
  • This configuration can be further developed in that the service calculator on a request with one Area selection for messages that are located outside of the selected area, do not affect any part of the location table transmits to the recipient. This prevents parts of the Location table that is currently for the user of the recipient are uninteresting, are stored in memory and thus possibly more interesting parts for the user be overwritten.
  • Telecommunication networks for the method according to the invention.
  • mobile recipients especially recipients in Motor vehicles
  • stationary receivers for example the ISDN or packet-switched services in question.
  • a non-volatile rewritable Memory which has a capacity which for storing at least some parts of the location table is sufficient that those parts of the memory Location table are writable to decode the each received message are required and that a Transceiver for a telecommunications network It is provided with what requests are sent and parts the location table can be received.
  • the transceiver is a terminal of a cellular network.
  • the location table does not contain only the information required for decoding, but also those that are user-friendly Playback are required, such as the names of the Places.
  • the receiver according to the invention provides that for a Output of the information required by the Location table are stored in a read-only memory. In order to needs the non-volatile rewritable memory not to be provided with a capacity which also for the unchangeable information, such as the place names, is sufficient.
  • the receiver according to the invention can without a location table in Memory to be shipped to the user. Through the Use of the receiver will be for the respective Parts of the location table required in the area of application Storage filed. If the reception behavior of the Receiver changes, for example because the RDS tuner regularly other stations are received (example: moving, selling the Vehicle, vacation trip), then "configures" itself Receiver automatically to the new conditions. The Selection, purchase and manual exchange of the Location table in the receiver is omitted.
  • Programs for establishing communication are included in the receiver the service computer of an information service provider contain.
  • the used in request and response Data packets for data transmission via mobile radio can be embedded in the prENV / 278/4/3/0015 described "General Message" formats. Be in the receiver the data received is written into the memory and there stored non-volatile. A received message can thus be decoded.
  • Requirements can be designed so that not only necessary for decoding a single message Location codes, but compiled according to other criteria Location codes are provided in the response. For example can be all in one by a single requirement certain area, on a certain street or in current location of a TMC transmitter containing location codes be requested. Through requirements designed in this way the period of time until all messages from a transmitter are decoded can be shortened.
  • the receiver shown in Fig. 1 has in itself known manner an antenna 1, a receiving part 2, a Stereo decoder 4, a NF amplifier 5 as well Power amplifiers 6, 7 and speakers 8, 9. That from the stereo multiplex signal delivered to the receiving part 2 in addition to the stereo decoder 4 fed to an RDS decoder 3, the output of which is connected to a microcomputer 13.
  • a microcomputer 13 serves to control the receiver for decoding, management, preparation for playback and selection of the TMC messages.
  • a keyboard 14 and a display device (display) 15 connected to the microcomputer 13 a keyboard 14 and a display device (display) 15 connected.
  • the output of the selected TMC messages can either be via the display 15 or as a voice output take place, for which purpose the microcomputer 13 via a Speech synthesizer 16 with an input 10 of the LF amplifier 5 is connected.
  • the microcomputer 13 is also non-volatile rewritable memory 17 connected to the Place table or parts of it.
  • a terminal 18 can be a conventional mobile phone, for example according to the GSM standard, the one used for data exchange has suitable interface with the microcomputer 13.
  • Fig. 2 shows a flow chart of an embodiment of the inventive method that as a program in Microcomputer 13 is implemented. It runs alongside one Set of other programs related to the Fig. 1 illustrated functions of the microcomputer.
  • a TMC message arrives at 22 and contains for example the location code (loc) 12273, the Extent (ext) 2 and the direction (dir) +.
  • DEC decoder
  • DEC also in the form of a Programs contained in the microprocessor 13
  • an attempt is made at 24 to decode the information the stored internal location table (LOCTAB) with the help the data loc: 12273, ext: 2, dir: + read out.
  • LOCTAB stored internal location table
  • the TMC message is decoded and output at 27.
  • the program ends.
  • the program is on every reception a TMC message started.
  • the program can be quasi simultaneously, expire so that in the waiting time between 29 and 33 other messages can be decoded.
  • a request to the Service calculator created by a service provider.
  • REQ request to the Service calculator created by a service provider.
  • TMC Transmission Control Channel
  • the requirement shown schematically at 31 becomes at 32 received, processed and answered by the service provider.
  • the response is also transmitted to the requesting recipient as a short message.
  • the Content of the answer (ANS) is shown schematically.
  • a practically executed place table means xxx "Aalen / Westhausen”, yyy "Heidenheim” and zzz "Ulm / Würzburg". This response is received at 34 by the recipient, after which he waited for the answer in program part 35.
  • the answer is an existing one Place table entered. This can be done by Additional storage is done if for those concerned Places no information in the saved place table are present or by replacing if a more recent one Received version of the relevant part of the location table becomes.
