Definitions

  • the invention relates to a method as indicated in the introductory part of claim 1, for the transfer of data to and from mobile terminals.
  • mobile terminal is taken to mean every kind of transportable unit that is capable of receiving wireless signals in a selective network. This applies in particular to handheld or vehicle-carried mobile phones and PDA devices with a communication facility.
  • the invention is based on the technology described in Norwegian Patent 311477. There, a method is described for the transfer of digital data, especially video signals, from a transmitter to a single receiver or to a group of receivers, where alternative transmission channels are sought for finding a cost saving alternative, as it comprises software that can choose between different connections based on capacity and cost.
  • a data signal with a query concerning transmission of a defined video signal is sent from a receiver to a transmitter.
  • a data package, that constitutes a part of the signal is transferred from the transmitter over a channel that is mainly chosen from optimal criterias based on capacity.
  • a subsequent part of the signal is transferred, as a second data package, over a low-price communication channel such as an Internet channel.
  • the received, non-consumed data is monitored in a buffer at the receiver.
  • a warning signal is sent from the receiver to the transmitter.
  • the transmitter initiates transmission of an additional data package of the signal, over the high-price channel, and thereafter continues with transmission of an additional signal over the low-price channel. This switching transmission continues, saving transmission capacity over the high-cost connection, and simultaneously maintains transmission capacity, which provides satisfactory data content in the transferred signal.
  • the main object of the invention is therefore to provide a method for transferring data signals to mobile phones, resulting in lower price, maintaining the quality of the transmission, and which makes it possible to selectively reach the separate receiver with one-way communication. It is a further object to provide a mobile terminal and a control unit, which can be used for implementing this method.
  • claims 6 and 7 define a new mobile terminal intended for performing this method
  • claim 8 defines a control unit for controlling the communication in the transmission system.
  • Such one-way service can be used as a complement to two-way mobile phones, for instance for: offering QoS (quality transmission) by sending the traffic alternately through both networks, being an alternative for random traffic to the mobile terminal, for reducing the transmission costs.
  • QoS quality transmission
  • the limited resource which is constituted by the frequencies, can be employed effectively by transmitting a one-way signal only on the transmitter which is in the area where the mobile terminal is located, and where it can receive. Hence, the transmitting costs are reduced. It is not necessary to transmit over a nationwide network, but only over the DVB-cell in which the mobile terminal is known to be located.
  • the network structure in the example comprises four mobile network transmitters MSI, MS2, MS3 and MS4, which each forms a cell MCI, MC2, MC3 and MC4. It may be a GSM network, a UTMS network, or some other mobile network. In practice, the cells will cover a substantial part of a region, in particular a country, and a central M will have contact with all the cells in the network, and contain information about where a given mobile terminal MT is located. It may also be a WLAN network. At the same time, the mobile terminal MT can receive signals in a DVB-cell. In the example, three ground-based transmitters TV1, TV2, TV3, with corresponding TV-cells TV-C1, TV-C2, TV-C3 are shown.
  • a mobile tenninal MT can have contact with transmitters in both networks.
  • the TV network will send out signals with a unique ID-code for the relevant network.
  • the mobile terminal receives this code, it can transmit information about the code over the mobile network, to the mobile central M, which then transfers a message to the central unit S.
  • the transfer between the central M and the central unit S often takes place via Internet.
  • the central unit S it can be determined in which TV-cell the mobile terminal mt is located, on the basis of stored information. This may, for instance, happen with the aid of a look up table that correlates the different numbers with information about geographic location.
  • the central unit S When the central unit S knows where the mobile terminal MT is located, and that it is able to receive signals, it may start transmission over the DVB-T or DVB-X channel.
  • the transmission can be controlled in such a way that it partially takes place over the DVB-T or -X channel, and partially over the ordinary mobile channel. Because DVB-T or -X can run with substantially lower cost than the mobile network, a cost reduction can be obtained in this manner.
  • the invention makes it possible to commercially utilize the spare bandwith.
  • the unique identification acquired by the mobile terminal can be the IP-address (or correspondingly) it gets when logging onto the Internet through a GPRS UTMS or a WLAN system. This address does not change until the customer logs off.
