1. Apparatus for transferring data from a network to a mobile device comprising:
- a transmitter arrangement having differing narrow and wide bandwidth links for transmitting data from the network to the mobile device, the transmitter arrangement being arranged for notifying, via the narrow bandwidth link, the mobile device of data awaiting transfer thereto from the network, the transmitter arrangement being arranged for transferring the data to the mobile device via the wide bandwidth link and the narrow bandwidth, the wide bandwidth link having a shorter range than the range of the narrow bandwidth link; and
an arrangement for transferring the data from the network to the mobile device and for causing transfer of the data, via the wide bandwidth link, to the mobile device unless the mobile device is outside of the range of the wide bandwidth link, in which case the data are selectively immediately transferred to the mobile device via the narrow bandwidth or are subsequently transferred to the mobile device via the wide bandwidth link when the mobile device is in range of the wide bandwidth link.

Abstract
The invention relates to a data transfer system and a method of data transfer. The invention aims to provide a high bandwidth channel between a mobile device, such as a mobile telephone and a network storing data, such as the Internet. A standard public land mobile network (PLMN) is used to notify the mobile device that there is data on the network awaiting download. The mobile device user then moves to within range of a high bandwidth short range (HBSR) base station to download the data more quickly than is possible over the PLMN.

5. A method of data transfer by using first and second communication links of differing bandwidths between a network and a mobile device, the first link having a narrower bandwidth and longer range than the second link, the method comprising:
-
notifying the mobile device of data awaiting transfer thereto from the network by transmitting a first signal from the network to the device via the first link; transferring the data from the network to the mobile device by transmitting a second signal from the network to the device via the first link or the second link; and
the transfer to the mobile device occurring via the second link immediately after the notifying step only if the mobile device is in the range of the second link, the transfer to the mobile device selectively occurring (a) immediately after the notifying step via the first link if the mobile device is not in the range of the second link or (b) subsequently to the notifying step via the second link when the mobile device is in the range of the second link. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A data transfer system comprising:
a network, a mobile device, a first transmitter and a second transmitter, the network being adapted to contain data, the mobile device being adapted to receive signals from both the first and second transmitters, the first transmitter being adapted to transmit a first narrow bandwidth long-range signal to the mobile device via a first narrow bandwidth long-range channel, the first signal indicating data on the network are available to be transferred to the mobile device, the second transmitter being adapted to transmit to the mobile device via a second wide bandwidth short-range channel, a second wide bandwidth short-range signal including the data, the mobile device and the first transmitter being arranged for selectively causing the first transmitter to transmit the data via the first channel and enabling the mobile device to selectively receive the data via the first and second channels;
the network being adapted to respond to a transmission resulting from an input by a user of the mobile device that the user wants to receive the data by transmitting the data to the second transmitter.- View Dependent Claims (24, 25, 26, 27, 28, 29)

30. A method of transferring data between a mobile device arrangement and a network arrangement via first and second communications links between the device arrangement and network arrangement, the first and second links respectively having narrow and wide bandwidths and long and short ranges, the method comprising:
-
sending a first narrow bandwidth signal from a first of the arrangements to the second of the arrangements via the first link, the first signal indicating that the first arrangement is ready to transmit data to the second arrangement, then sending a second wide bandwidth signal from the first arrangement to the second arrangement via the second link, the second signal including the data; and scheduling the sending of the data from the first arrangement to the second arrangement via one of the first and second links, and transferring the data from the first arrangement to the second arrangement via one of the first and second links based on the schedule.
