  • a mobile communication device receives a sub-part of a data item from the one or more storage devices. This reduces the data transfer over the second wireless data network.
  • the first wireless data network may be a relatively fast wireless data network with local data access and the second wireless data network may be a relatively slow wireless data network with global data access.
  • an operator of a fast first wireless data network can offer sub-parts of data items to users of mobile communication devices. This allows an operator of a first wireless data network to encourage users to connect to their network to receive data items rather than users receiving data items over a second, typically slower and more costly, wireless data network.
  • the method may further comprise:
  • the second sub-part of the data item that is received over the slow global network is sent to the one or more storage devices over the fast local network.
  • the data becomes local and the one or more storage devices can allow other mobile communication devices to access potentially the entire data item over the fast local network. This reduces data transfer on the slow global network and results in a better user experience.
  • the sending of the second sub-part of the data item for storage is outside the typical flow of data from a data host. Therefore the storage of sub-parts of data items by the storage device may be independently controlled without affecting the communication between the one or more data hosts and the mobile communication device. This allows the storage of a sub-part of the data item to be tailored for preferable use in specific environments, such as small geographic areas.
  • the method may further comprise:
  • the data item may represent a video.
  • the first sub-part may represent the beginning portion of a video.
  • video files are typically monolithic and, using this method, can be split and transferred over multiple networks in sub-parts. More important sub-parts of the video (such as the sub-part that includes the start of the video) can be transferred over the first, faster, wireless data network so that a user does not have to wait for the video to be received over a the second, slower, wireless data network.

  • Users 104 and 108 are using their smart phones 106 and 110 independently but since they are at the same place at the same time, there is a high chance that they will download similar data. For example, many users on their commute to work in the morning check the weather forecast for the day and watch highlights of the most popular sports events that took place overnight. It is a waste of resources that each user downloads the same data items over the cellular network via base station 120.
  • the same data in this context may not necessarily be a whole data item such as an entire video file. That is, users typically not only download the same data items but the same sub-parts of the data items such as the beginning portion of a video. Further, bandwidth between the base station 120 and the users' smart phones 106 and 110 can be reduced by providing data storage on a storage device 112 such that each sub-part of a data item is downloaded only once and then subsequently accessed from the storage device 112 multiple times.

In the example where the data item represents a video, then the user may be able to use the video by watching the video on the mobile communication device 106. The mobile communication device 106 may continue to receive additional sub-parts of the data item until the whole data item is received.

  • the sub-part being sent by the mobile communication device 402 does not get stored on the storage device 406.
  • the data store on the storage device 406 is close to its capacity. For example, where other data is being transmitted to other users it is not worth storing additional data as the other data would have to be deleted to make space and this would likely have negative effects on the users' experience.
  • only one storage device 406 is used. However, it is possible that multiple storage devices could be present in any given area.
  • the storage devices may have their own individual data store and wireless network.
  • the mobile communication device 402 may then be able to select which storage device it wishes to receive the data is available from. The selection may be based on numerous factors such as the available content or based on signal strength. All other features would operate the same as a single storage device.
  • the device 402 which has the same configuration as device 200 of Fig. 2, first detects the first wireless data network 404 by searching for a Wifi network with a predefined network identifier, such as an SSID of "Storage Device WLAN".
  • a predefined network identifier such as an SSID of "Storage Device WLAN”.
  • Predefined may also mean that the network identifier follows certain predefined rules, such as it starts with "Storage Device” and is followed by an identifier of the respective storage device.
  • the first wireless data network may be secure and the authentication credentials may be stored on mobile communication device 402.
  • the access to the first wireless data network 404 may also be granted using user authentication via the application installed on mobile communication device 402.
  • the device 402 establishes a connection to the storage device 406 over the local Wifi network 404. The device 402 can then determine whether certain data is accessible on storage device 406 as explained before.
  • Fig. 5 illustrates an example user interface on a mobile communication device 402.
  • the video preview marked with a red tab 502 indicates that a sub-part of the video is not accessible from the storage device 406.
  • the video preview marked with a green tab 504 indicates that a sub-part of the video is accessible from the storage device 406 over the first wireless data network 404.
  • the sub-part of the video is received over the first wireless data network 404.
  • a second sub-part of the data item that is different from the first sub-part of the video is received over a second wireless data network 408.
  • the user interface is not limited to the use of green and red tabs.
  • indicia such as additional colours, icons or numerals which can be used to indicate that a sub-part of the video is available on the storage device 406.
  • an orange tab might be used to indicate that a sub-part of the video is available but is less than the whole video, where a blue tab might be used to indicate a threshold amount of the video is available on the storage device 406.
  • a progress bar that is a visual indication of the amount of the video available on the storage device 406 could be used, or simply a number representing the percentage of the whole video may be displayed.
  • Suitable computer readable media may include volatile (e.g. RAM) and/or non-volatile (e.g. ROM, disk) memory, carrier waves and transmission media.
  • Exemplary carrier waves may lake the form of electrical, electromagnetic or optical signals conveying digital data steams along a local network or a publically accessible network such as the internet.
  • “equalising” or the like refer to the action and processes of a computer system, or similar electronic computing device, that processes and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.

Abstract

La présente invention concerne l'utilisation de dispositifs de stockage pour recevoir des données destinées à être utilisées dans un dispositif de communication mobile. En particulier, la présente invention concerne un procédé, un logiciel et un système pour recevoir un élément de données (409) à utiliser dans un dispositif de communication mobile. Initialement, une première sous-partie (405) de l'élément de données, accessible à partir d'un ou de plusieurs dispositifs de stockage (406) sur un premier réseau de données sans fil, est déterminée. Ensuite, le dispositif de communication mobile reçoit la première sous-partie (405) de l'élément de données du ou des dispositifs de stockage (406) sur le premier réseau de données sans fil (404). Le dispositif de communication mobile reçoit ensuite une seconde sous-partie de l'élément de données (407), qui est différente de la première sous-partie de l'élément de données, sur un second réseau de données sans fil (408) d'un type différent du premier réseau de données sans fil.
