Definitions
- the invention relates to a method for transmission information to a mobile recipient, e.g. at one Pager or to a handset of a cellular or satellite telecommunications system.
- the invention also relates to a radio transmitter for broadcasting a radio signal, with an encoder for compression and digital coding of an analog input signal, with a modulator to which the encoded signal is supplied, as well as with one in the short-medium or long wave range working high frequency stage, the broadcast signal shutdown with fluctuating bit rate.
- the invention also relates to a mobile device Receiver that arrives to receive blocks of information digitally encoded information and for storage and / or display of the decoded information is.
- Usual pagers and mobile phones work in a frequency range from 100 MHz to a few GHz and are based solely on physical conditions can not be used everywhere, because the Radio waves through obstacles such as walls, soil, metal walls etc. are shielded.
- a handset cannot be reached for other reasons be, for example, if it is in a region without a network infrastructure of the network operator because it is for security reasons must be switched off, as in aircraft or intensive care units, or because other physical Effects such as the Doppler effect in otherwise moving vehicles, Fading, etc. do not allow a connection.
- the handset user If the handset user establishes a connection wants, he can use the satellite phone or its antenna put it in the correct line-of-sight position. The user the handset can not ensure that during the antenna of his when traveling in vehicles of any kind Satellite phones are in a "line-of-sight" position located, it is therefore not for other telephone subscribers reachable and cannot receive your call.
- the invention is based on a method of the type mentioned, in which according to the invention a specific one to be sent to the recipient Information from at least one broadcaster in addition to a radio signal is emitted, the transmitter after a digital method is modulated, in which the data rate through data compression and a fluctuating bit rate is adapted to the broadcast signal to be transmitted, and in Periods in which the maximum possible bit rate is not is sent by the difference between the maximum bit rate and the one claimed by the broadcast signal Free channel capacity given with the specific bit rate Information is replenished.
- the invention offers the advantage that for the transmission of information, in particular a short message in the sense of well-known Pager news, existing facilities, namely the radio stations for short, medium and long waves can be used.
- existing facilities namely the radio stations for short, medium and long waves can be used.
- the accessibility of the mobile Receiver is significantly improved, the frequency range of the broadcast band used is aware of the requirements can be chosen accordingly.
- the invention therefore does not require the establishment of new transmitters, what about the scarce frequencies in the KW, MW and LW range anyway encounter difficulties, rather must only existing transmitters are modernized without new locations or antennas would be required.
- the broadcast signals are scaled dynamically or it a Huffman variable length is used to encrypt the broadcast signals Code used.
- bit congestion of the to be sent exceeding the predetermined dimension specific information due to insufficient channel capacity the bit rate of the encoded broadcast signals temporarily lowered becomes. This can, for example, if more complex Broadcast signals have led to such a bit jam that Transmission of the specific information usually the required bit rate reduction for the broadcast signal will hardly be noticed.
- the broadcasting station or stations in the range from 150 kHz to 30 MHz is or will be operated, the simultaneous Broadcast on different frequencies, e.g. in the L wound can bring special advantages in the MW range.
- the task also starts with a radio station cited type solved, in which according to the invention the encoder specific information is also supplied and the encoder is set up in time segments, in which the maximum possible bit rate is not sent, by the difference between the maximum bit rate and the given free bit rate claimed by the broadcast signal Fill channel capacity with the specific information
- the encoder specific information is also supplied and the encoder is set up in time segments, in which the maximum possible bit rate is not sent, by the difference between the maximum bit rate and the given free bit rate claimed by the broadcast signal Fill channel capacity with the specific information
- An expedient variant provides that the encoder does this is set up for higher priority broadcast signals Forward transmission as specific information.
- the encoder is set, the priority of the signals from headers read from signal blocks.
- a cheap variant is characterized in that the encoder is set up from a predeterminable bit jam the bit rate of the specific information to be sent temporarily lower the coded broadcast signal.
- a mobile receiver can do the above serve specified type, in a process with the named Features and for receiving a transmitter with the related is also used above features.
- the mobile receiver can be contained in a pager or it can be used as an additional receiver in a mobile device or be included in a satellite phone.
- the base stations FIP1, FIP2 of a mobile radio network e.g. a GSM network, the cells of which are symbolic as dash-dotted circles are drawn.
- a cell there is a POP handset.
- the base stations FIP1, FIP2 and others are assigned a base station controller BSC and this is superordinate to a mobile radio switching unit MSC, access to the so-called Visitor Location Register VLR or the Home Location Register HLR and others not shown Units, such as an authentication register.
- the base station controller BSC stands over a suitable one Interface with a landline, e.g. an ISDN network ISDN in connection.
- Fig. 1 are also two radio transmitters TRA, TRA 'with antennas SAN, SAN '.
- the supply of radio broadcasters with a radio signal AUD namely an audio signal e.g. from a radio studio RFS, what for the broadcaster TRA is indicated with a direct line, whereas the Transmitter TRA 'in connection with the Studio RFS via a network NET stands.
- the transmitters TRA, TRA ' are in principle connected to the NET network Connection, which is symbolically indicated here with an open block is. It may be the cellular network Fixed network or a superordinate network. It is possible but also a direct connection of a TRA transmitter, TRA 'with a base station FIP1, FIP2.
- Fig. 1 further shows a communications satellite SAT, a satellite phone SPP and a BST ground station serving the communications satellite SAT is assigned and with at least that Communication network NET is connected.
- the radio broadcaster TRA come information from a satellite receiver SRE, which the satellite receiver receives from the satellite SAT receives.
- a dashed line can also be used direct connection between the ground station BST and the transmitter TRA exist.
- a handset POP In anticipation of FIG. 4, a handset POP can be seen has an HF part HFT which is connected to an antenna ANT stands.
- the SPP handset also contains a digital one Signal processor DSP and an audio unit AUD, which too a speaker LSP and a microphone MIC connection.
- An essential part of the handset is a Receiver RWE, for example with two ferrite antennas FA1 and FA2 is fitted to each other at right angles stand to avoid directional dependency.
- the RWE receiver has a single-channel design and can be a frequency in the LW, MW or KW range received, i.e. it operates in a frequency range of, for example 148.9 kHz to 30 MHz. At higher frequencies if necessary, rod antennas instead of ferrite antennas be used.
- the receiver RWE can also be tuned, especially in the Be the sense of a scanner and have a frequency memory FRM.
- the receiver RWE can then be set up to those radio stations which have the greatest field strength and / or have the lowest bit error rate, determine and in which Store frequency memory FRM.
- the Frequency memory FRM also stored frequency values that specified by the NET network and via the usual mobile radio link to the POP handset.
- Fig. 4 is also intended to represent the satellite telephone SPP and therefore a parabolic antenna PAN is shown in broken lines, that with a SPP satellite phone instead of the otherwise rod-shaped antenna ANT occurs.
- the radio transmitter TRA or TRA ' consists of one Encoder COD and a modulator MOD, the latter being a High-frequency power stage HFS controls the antenna SAN fed.
- the encoder COD is e.g. by the studio RFS incoming audio signal AUD, here also called “broadcast signal”, supplied as well as a channel coding CCO and the specific information INF based on a priority selection PRI receives three different messages in this example NR1, NR2 and NR3 are supplied, for example one Message NR1 for a mobile phone POP, a message NR2 for a satellite phone SPP and a message NR3 for one Pager PAG, which is also shown in Fig. 1 and which also contains a receiver which receives the signals the radio station used can receive.
- the radio transmitter RFS works digitally and the data rate is due to data compression and a fluctuating bit rate continuously adapted to the broadcast signal to be transmitted.
- the signals AUD can be scaled dynamically, it can be encoded using a Huffman variable-length code be applied. More details on digital broadcasting on long, medium and short wave can the "system description DMW ", Technical Report of Irish Industries, Internationale Funkauswolf 1997, Berlin. Digital modulation methods for are also described radio in the articles "Digital under 30 MHz", Hans Weber, ELRAD 1997, No. 10, pages 60 to 63 and "Digitale Shortwave ", Hans Weber, Funkschau 3/98.
- the broadcast channel has one maximum bit rate MAX, due to the bandwidth of the broadcasting station in the LW, MW and KW range - mostly 9 kHz - conditional and is already set in the modulator and the one mentioned above System for the audio data is 24 kbit / sec.
- This maximum bit rate is only at very complex or higher frequencies Audio signals required.
- Fig. 3 that is for one selected time period required audio data stream hatched.
- the remaining "free space” is now with specific information, here news NR1, NR2 and NR3 "filled up".
- the modulator MOD is set up to the additional data blocks of suitable length to the insert appropriate times in the data stream, for which the Means suitable for a person skilled in the art, such as elastic or controllable ones Buffer memory are available.
- the priority selection described in connection with FIG. 2 PRI can of course also be part of the modulator MOD, how it doesn't matter which "blocks" in the Transmitters (or receivers) are present because of signal processing primarily done in software in processors.
- the Priority of the individual signals or information blocks can by a short, expediently in a block header contained classification take place, whereby naturally the Broadcast signal AUD practically always given absolute priority becomes. However, exceptions could be signals of the specific Represent information such as the disaster warning serve.
- Fig. 5 shows schematically a block BLO which contains the information INF or part of this information contains INF.
- the block can have a predetermined bit length and apart from a header HEA first a block length information BIN, furthermore an identification IDE of the subscriber to be called and finally contain a message field NAF.
- Message field can be an identification regarding the IDS calling subscriber, e.g. whose number should be included, as well as a short message to the called subscriber, e.g. "Call from 7pm".
- Blocks BLO offer advantages, but is by no means mandatory. You can also find other specific information in be contained in the block or in a plurality of blocks, such as test fields or the like.
- the RWE radio receiver is the handset POP or SPP always on, i.e. ready to receive.
- a connection between a base station FIP1, FIP2 and the TRA broadcast information INF can from the handset POP, SPD be ignored or rejected.
- there is no radio connection to a satellite or a base station so e.g. receive a call request via radio, e.g. the caller's phone number, i.e. the identification IDS in the block BLO.
- the POP, SPD handset can then be given to the user via ringer or via visual display display the call request so that the user then the handset to a location with appropriate reception quality, e.g.
- the invention thus uses existing long-wave or medium-wave transmitters, if necessary also short-wave transmitters to short Messages, called "specific information", to mobile Transfer recipient.
- These mobile receivers can only set up to receive these messages be, as is the case with a pager, for example.
- you can also use your own RWE receiver as an add-on in Mobiloder Satellite phones can be provided so that for the corresponding Mobile or satellite phone specific messages can be received, saved and also displayed.
- SMS Short Mail Service
- the invention thus enables an essential improved accessibility of the pager or mobile / satellite phone, which can still be improved if for Transmission of specific information not just a frequency but different frequencies, e.g. longwave and short waves are used.
- specific information not just a frequency but different frequencies, e.g. longwave and short waves are used.
- RDS or DAB Digital Audio Broadcast
