Description

Framgangsmåte, mobil terminal og styringsevnet for overføring av datamengder Procedure, mobile terminal and the control capability for the transfer of data volumes

Oppfinnelsen gjelder en framgangsmåte som angitt i innledningen til patentkrav 1, for overføring av datamengder til og ira mobile terminaler. Med "mobil terminar' menes alle former for flyttbare enheter som er i stand til å motta trådløse signaler i et selektivt nettverk. Det gjelder særlig håndholdte eller kjøretøysbårne mobiltelefoner og PDA med kommunikasjonsdel. Oppfinnelsen omfatter dessuten en mobil terminal og en styringsenhet for gjennomføring av denne framgangsmåten. The invention relates to a method as stated in the introduction to patent claim 1, for the transfer of data quantities to and from mobile terminals. By "mobile terminal" is meant all forms of mobile devices that are capable of receiving wireless signals in a selective network. This applies in particular to hand-held or vehicle-borne mobile phones and PDAs with a communication part. The invention also includes a mobile terminal and a control unit for implementing this the procedure.

Bakgrunn Background

Oppfinnelsen har utgangspunkt i den teknologien som er beskrevet i norsk patent 311477. Det dreier seg der om en framgangsmåte for overføring av digitale datamengder, særlig videosignal, fra en sender til en enkelt mottaker eller ei gruppe mottakere, hvor det søkes etter alternative overføringskanaler for å finne et kostnadsgunstig alternativ, idet det omfatter programvare som kan velge mellom ulike forbindelsesveger ut fra kriterier for kapasitet og kostnad. Det sendes et datasignal med en forespørsel om sending av et angitt videosignal fra en mottaker til en sender. En datapakke som utgjør en del av signalet overføres fra senderen over en kanal som hovedsakelig velges ut fra optimale kriterier basert på kapasitet. En påfølgende del av signalet overføres som en andre datapakke over en lavpris kommunikasjonskanal, si som en Internettkanal. Det gjennomføres en overvåking av den mottatte, ikke-konsumerte datamengden i et bufferlager hos mottakeren. Ved registering av en ikke-konsumert datamengde (buffermengde) under et visst nivå hos mottakeren, blir det sendt et varselsignal fra mottakeren til senderen. Ved mottak av dette varselsignalet initierer senderen overføring av en ytterligere datapakke av signalet over høgpriskanalen, for deretter å fortsette med overføring av en ytterligere signalmengde over lavpriskanalen. Denne vekseloverføringen fortsetter for å spare overføringskapasitet over høgprisforbindelsen, og samtidig opprettholde en overføringskapasitet som gir tilfredsstillende datainnhold i det overførte signalet. The invention is based on the technology described in Norwegian patent 311477. It concerns a procedure for the transmission of digital amounts of data, especially video signals, from a transmitter to a single receiver or a group of receivers, where alternative transmission channels are searched for in order to find a cost-effective alternative, as it includes software that can choose between different connection routes based on criteria for capacity and cost. A data signal requesting the transmission of a specified video signal is sent from a receiver to a transmitter. A data packet that forms part of the signal is transmitted from the transmitter over a channel that is mainly selected based on optimal criteria based on capacity. A subsequent part of the signal is transmitted as a second data packet over a low-cost communication channel, say as an Internet channel. A monitoring of the received, non-consumed amount of data is carried out in a buffer storage at the receiver. When registering an unconsumed amount of data (buffer amount) below a certain level at the receiver, a warning signal is sent from the receiver to the transmitter. On receipt of this warning signal, the transmitter initiates the transmission of a further data packet of the signal over the high-price channel, and then continues with the transmission of a further amount of signal over the low-price channel. This alternating transmission continues in order to save transmission capacity over the high-cost connection, and at the same time maintain a transmission capacity that provides satisfactory data content in the transmitted signal.

Det er foreslått å kombinere mobiltelefon og TV-kringkasting, f.eks. i det som er kalt DVB-(T- eller X-) standarden, for overføring av musikk, filmklipp og andre multimedia-kommunikasjon til mobiltelefoner. Dette systemet har imidlertid problemer med datakapasitet. It has been proposed to combine mobile phone and TV broadcasting, e.g. in what is called the DVB-(T or X) standard, for the transmission of music, film clips and other multimedia communications to mobile phones. However, this system has data capacity issues.

Det er også foreslått å kombinere dette med GPRS/UTMS- samt WLAN-systemet for overføring av videosignal. Men til nå har ikke disse forslagene gitt vellykket audiovisuell overføring med tilfredsstillende kapasitet for forbrukermarkedet. It is also proposed to combine this with the GPRS/UTMS and WLAN system for video signal transmission. However, until now these proposals have not provided successful audiovisual transmission with satisfactory capacity for the consumer market.

Fra artikkelen "Broadcasting and mobil telecommunications interworking" i EBU Technical Review, Januar 2003er det kjent å overføre data til og fra mobile terminaler, der den mobile terminalens posisjon først identifiseres. I en styringssentral fastlegges posisjonen til TV-senderen og det utløses signaloverføring fra den mobile terminalen til TV-senderen. I det kjente systemet kreves et mobilnett for overføring av informasjon til mottakerne. From the article "Broadcasting and mobile telecommunications interworking" in the EBU Technical Review, January 2003, it is known to transfer data to and from mobile terminals, where the mobile terminal's position is first identified. In a control center, the position of the TV transmitter is determined and signal transmission from the mobile terminal to the TV transmitter is triggered. In the known system, a mobile network is required for the transmission of information to the recipients.

Formål Purpose

Hovedformålet med oppfinnelsen er derfor, å komme fram til en framgangsmåte for overføring The main purpose of the invention is therefore to arrive at a procedure for transfer

av datasignal til mobile terminaler, som gir lavere pris, samtidig som kvaliteten på overføringen opprettholdes og som gjør det mulig å nå den enkelte mottaker selektivt med envegs kommunikasjon. of data signal to mobile terminals, which gives a lower price, while maintaining the quality of the transmission and which makes it possible to reach the individual recipient selectively with one-way communication.

Videre er det et formål å komme fram til en mobil terminal og en styringsenhet som kan nyttes for å gjennomføre denne framgangsmåten. Furthermore, it is an aim to arrive at a mobile terminal and a control unit that can be used to carry out this procedure.

Oppfinnelsen The invention

Oppfinnelsen er angitt i patentkrav 1, idet patentkrav 2-5 angir særlig fordelaktige utførelsesformer. The invention is stated in patent claim 1, with patent claims 2-5 specifying particularly advantageous embodiments.

Det er altså sentralt, at det sendes ut en unik kode fra en bakkebasert TV-sender i nærheten av den mobile enheten og at denne koden mottas av en mobil terminal og sendes sammen med en ID-kode for den mobile terminalen over et annet overføringsnettverk, for mottak i en styringssentral. It is therefore essential that a unique code is broadcast from a terrestrial TV transmitter in the vicinity of the mobile device and that this code is received by a mobile terminal and sent together with an ID code for the mobile terminal over another transmission network, for reception in a control centre.

Videre angir patentkrav ti og 7 en ny mobil terminal beregnet for å gjennomføre denne framgangsmåten og patentkrav 8 en styreenhet for å styre kommunikasjonen i overføringssystemet. Furthermore, patent claims ten and 7 state a new mobile terminal designed to carry out this procedure and patent claim 8 a control unit to control the communication in the transmission system.

Med en slik framgangsmåte og utstyr blir det mulig å motta DVB i stedet for TV-signaler og laste ned video til en mobil terminal til lavest mulig pris med bibeholdt kvalitet. With such a procedure and equipment, it becomes possible to receive DVB instead of TV signals and download video to a mobile terminal at the lowest possible price with maintained quality.

En slik en-vegs tjeneste kan bruke som komplement til tovegs mobiltelefon, for eksempel for: Such a one-way service can be used as a complement to a two-way mobile phone, for example for:

- å tilby QoS (kvalitetsoverføring) ved å sende trafikken vekselvis gjennom begge nettene, - to offer QoS (quality transmission) by sending the traffic alternately through both networks,

- å være et alternativ for vilkårlig trafikk til den mobile terminalen, for å senke overføringskostnadene, - to be an alternative for arbitrary traffic to the mobile terminal, to lower transmission costs,

Den begrensete ressurs som frekvensene utgjør kan utnyttes effektivt ved å sende en-vegs signal bare på senderen i det området hvor den mobile terminalen befinner seg og kan motta. Dermed reduseres overføringskostnadene. Det er ikke nødvendig å sende over et landsdekkende nett, men bare over den DVB-cellen som man vet den mobile terminalen befinner seg i. The limited resource that the frequencies constitute can be used effectively by sending a one-way signal only on the transmitter in the area where the mobile terminal is located and can receive. This reduces the transmission costs. It is not necessary to transmit over a nationwide network, but only over the DVB cell in which you know the mobile terminal is located.

Kombinasjonen av kunnskap om en mobil terminal, henholdsvis den bærende personen, og vedkommendes geografiske posisjon og vedkommendes hastighet når det er tale om et kjøretøy, gjør det mulig å distribuere personlig informasjon, f.eks. reklame, som altså kan sendes over et en-vegs nett. The combination of knowledge about a mobile terminal, respectively the person carrying it, and the relevant geographical position and the relevant speed in the case of a vehicle, makes it possible to distribute personal information, e.g. advertising, which can therefore be sent over a one-way network.

Eksempel Example

Oppfinnelsen er nedenfor beskrevet nærmere ved henvisning til tegningen som illustrerer en nettstruktur som er tilrettelagt for gjennomføring av oppfinnelsen. The invention is described in more detail below with reference to the drawing which illustrates a network structure which is arranged for carrying out the invention.

Nettstrukturen omfatter i eksemplet fire mobilnett-sendere MS 1, MS2, MS3 og MS4 som hver danner en celle MC 1. MC2, MC3, MC4. Det kan være tale om et GSM-nett, et UTMS-nett elle et annet mobilnett I praksis vil cellene dekke den vesentlig delen av et territorium, særlig et land, og en sentral M vil ha kontakt med alle cellene i nettverket og ha informasjon om hvor en gitt mobil terminal MT befinner seg. Det kan også være tale om et WLAN-nett. In the example, the network structure comprises four mobile network transmitters MS 1, MS2, MS3 and MS4, each of which forms a cell MC 1. MC2, MC3, MC4. This could be a GSM network, a UTMS network or another mobile network. In practice, the cells will cover a significant part of a territory, especially a country, and a central M will have contact with all the cells in the network and have information about where a given mobile terminal MT is located. It can also be a WLAN network.

Samtidig med dette kan den mobile terminalen MT ta imot signal i en DVB-celle. I eksemplet er det vist tre bakkebaserte sendere TVI, TV2, TV3 med tilsvarende TV-celler TV-Cl, TV-C2, TV-C3. At the same time, the mobile terminal MT can receive a signal in a DVB cell. In the example, three ground-based transmitters TVI, TV2, TV3 are shown with corresponding TV cells TV-Cl, TV-C2, TV-C3.

En mobil terminal MT kan ha kontakt med sendere i begge nettene, TV-nettet vil sende ut signal med en unik ID-kode for det aktuelle nettet. Når den mobile terminalen mottar denne koden, kan den overføre opplysning om den over mobilnettet til mobilsentralen M. som så overfører melding til sentralenheten S. Overføringen mellom mobilsentralen M og sentralenheten S skjer ofte via Internett. A mobile terminal MT can have contact with transmitters in both networks, the TV network will send out a signal with a unique ID code for the relevant network. When the mobile terminal receives this code, it can transmit information about it over the mobile network to the mobile exchange M. which then transmits the message to the central unit S. The transfer between the mobile exchange M and the central unit S often takes place via the Internet.

I sentralenheten S kan det på grunnlag av lagrete opplysninger fastslås i hvilken TV-celle den mobile terminalen befinner seg. Dette kan for eksempel skje ved hjelp av en tabell som korrelerer de unike numrene med opplysning om geografisk plassering.. In the central unit S, it can be determined on the basis of stored information in which TV cell the mobile terminal is located. This can, for example, be done using a table that correlates the unique numbers with information about geographical location.

Når sentralenheten S vet hvor den mobile terminalen befinner seg og at den kan motta signal, kan den starte utsendelse over DVB-T eller - X-kanalen. When the central unit S knows where the mobile terminal is located and that it can receive a signal, it can start broadcasting over the DVB-T or - X channel.

Overføringen kan styres slik at den går delvis over DVB-T eller -X kanalen og delvis over den vanlige mobilkanalen. Fordi DVB-T eller -X kanalen kan drives med vesentlig lavere kostnader enn mobilnettet, kan det på denne måte oppnås en kostnadssenkning. Over en vesentlig del av døgnet sendes det ofte ikke TV-signal i disse nettene. Oppfinnelsen gjør det mulig å utnytte den ledige kapasiteten kommersielt. The transmission can be controlled so that it goes partly over the DVB-T or -X channel and partly over the normal mobile channel. Because the DVB-T or -X channel can be operated at substantially lower costs than the mobile network, a cost reduction can be achieved in this way. Over a significant part of the day, there is often no TV signal on these nights. The invention makes it possible to exploit the free capacity commercially.

Dette betyr altså et en bruker av en mobil terminal MT i en viss posisjon kan fange inn identifikasjonen til nærmeste TV-sender og overføre den sammen med opplysning om sin egen identitet til sentralenheten S som instruks om at overføring over signalvegen S-TV ønskes. This means that a user of a mobile terminal MT in a certain position can capture the identification of the nearest TV transmitter and transmit it together with information about his own identity to the central unit S as an instruction that transmission over the signal path S-TV is desired.

Den unike identifikasjonen som den mobile terminalen får kan være den IP-adressen (eller tilsvarende ) som den får når den logger seg på Internett gjennom GPRS/UTMS eller et WLAN-system. Denne adressen forandrer seg ikke før kunden logger seg av igjen. The unique identification that the mobile terminal receives can be the IP address (or equivalent) that it receives when it logs on to the Internet through GPRS/UTMS or a WLAN system. This address does not change until the customer logs off again.

Overgangen fra ett overføringssystem til et annet kan skje uten at det merkes. Dette betyr at et bakkebasert TV-nett kan drive et slikt overføringssystem uten å ha spesiell avtale med leverandøren av mobiltjenesten. The transition from one transmission system to another can happen without being noticed. This means that a terrestrial TV network can operate such a transmission system without having a special agreement with the provider of the mobile service.
