Abstract

A method, apparatus, and system for automatically sharing data resources between Bluetooth devices. A Bluetooth device is paired with a “trusted” Bluetooth device. When paired devices are found, the Bluetooth device automatically allows the other device to present a virtual representation of data that is shared. The shared data can be selectively downloaded for use by the other device as long as the devices are in proximity. In an alternate embodiment, the devices may share pairing information with a network, so that the same shared resource can be made available at a large number of access points but specifically only for one paired, trusted device.

Claims

1. A method of sharing data on wireless communication devices, comprising:

pairing a first wireless communication device and a second wireless communication device;

designating a file or a folder residing in the second wireless communication device as sharable with the first wireless communication device; and

making a selection at the first wireless communication device that causes data from at least a portion of the file or at least a portion of the folder to be wirelessly transmitted from the second wireless communication device to the first wireless communication device,

wherein, when the second wireless communication device is no longer in proximity of the first wireless communication device, the first wireless communication device deletes the data that was wirelessly transmitted from the second wireless communication device to the first wireless communication device due to the selection.

2. The method according to claim 1, comprising:

pairing the first wireless communication device with a plurality of second wireless communication devices.

3. The method according to claim 1, comprising:

browsing an index or a listing that is provided at the first wireless communication device when it is determined that the second wireless communication device is in proximity with the first wireless communication device.

4. The method according to claim 3, wherein the index or the listing corresponds to the file or the folder residing in the second wireless communication device.

5. The method according to claim 3, wherein the selection is made from the index or the listing.

6. The method according to claim 1, wherein the selection causes at least a portion of an address book residing in the second wireless communication device to be wirelessly transmitted from the second wireless communication device to the first wireless communication device.

7. The method according to claim 1, wherein the file or the folder is not entirely copied onto the first wireless communication device.

8. The method according to claim 1, comprising:

designating a second file or a second folder residing in the first wireless communication device as sharable with the second wireless communication device.

9. The method according to claim 1, wherein the second wireless communication device propagates pairing information to a network of network devices, and

wherein each network device is allowed to make a shared resource available on the first wireless communication device.

10. A system for sharing resources on wireless communication devices, comprising:

at least two paired wireless communication devices that comprise a first wireless communication device and a second wireless communication device, wherein the first wireless communication device is paired with the second wireless communication device, the second wireless communication device having a category of files residing in the second wireless communication device that is designated as sharable with the first wireless communication device, the first wireless communication device presenting a virtual representation of the sharable category of files when the first wireless communication device and the second wireless communication device are in proximity to each other, wherein a selection of a portion of the virtual representation at the first wireless communication device causes at least a portion of the sharable category of files to be wirelessly transmitted from the second wireless communication device to the first wireless communication device, and wherein, when the second wireless communication device is no longer wirelessly linked to the first wireless communication device, the first wireless communication device automatically deletes data that was wirelessly transmitted from the second wireless communication device to the first wireless communication device due to the selection from the virtual representation.

11. The system according to claim 10, wherein the first wireless communication device deletes the virtual representation when the first wireless communication device and the second wireless communication device are no longer in proximity.

12. The system according to claim 10, wherein the category of files comprises an address book.

13. The system according to claim 10, wherein the category of files is not entirely loaded onto the first wireless communication device.

14. The system according to claim 10, wherein the first wireless communication device has a second category of files residing in the first wireless communication device that is designated as sharable with the second wireless communication device, wherein the second wireless communication device presents a second virtual representation of the sharable second category of files when the first wireless communication device and the second wireless communication device are in proximity to each other, and wherein a selection of a portion of the second virtual representation at the second wireless communication device causes at least a portion of the sharable second category of files to be wirelessly transmitted from the first wireless communication device to the second wireless communication device.

15. The system according to claim 10, wherein the second wireless communication device propagates pairing information for the first wireless communication device to a network, and wherein a plurality of devices of the network are allowed to share a shared resource with the first wireless communication device.

16. In one or more integrated circuits in a first wireless communication device, one or more protocol stacks that perform a method, the method comprising:

pairing with a second wireless communication device;

detecting a proximity of the second wireless communication device;

presenting a virtual file or a virtual folder on a user interface of the first wireless communication device, the virtual file or the virtual folder representing a particular file or a particular folder residing in the second wireless communication device, the particular file or the particular folder being designated as accessible to the first wireless communication device; and

causing at least a portion of the particular file or at least a portion of the particular folder residing in the second wireless communication device to be wirelessly transmitted from the second wireless communication device to the first wireless communication device when a selection is made from the virtual file or the virtual folder, wherein the one or more integrated circuits delete the virtual file or the virtual folder when a link between the first wireless communication device and the second wireless communication device is no longer valid.

17. The method according to claim 16, wherein the one or more integrated circuits are paired with a plurality of wireless communication devices.

18. The method according to claim 16, wherein the particular file or the particular folder corresponds to an address book residing in the second wireless communication device.

19. The method according to claim 16, wherein only a subset of the particular file or only a subset of the particular folder is wirelessly transmitted from the second wireless communication device to the first wireless communication device.

20. The method according to claim 16, comprising:

designating a second particular file or a second particular folder residing in the first wireless communication device as accessible to the second wireless communication device; and

causing at least a portion of the second particular file or at least a portion of the second particular folder to be wirelessly transmitted to the second wireless communication device when a second virtual file or a second virtual folder presented at the second wireless communication device is selected at the second wireless communication device, the second virtual file or the second virtual folder corresponding to the particular file or the particular folder.
