Abstract

Disclosed are a method and apparatus for downloading content using NFC. The content-downloading method of the present invention is performed by a first device, and comprises the steps of: transmitting a content-downloading request for requesting a download of content using a second device; receiving a confirmation to the content-downloading request from the device which has received the content-downloading request; receiving a wake-up request from the second device; and receiving, from the second device, the content downloaded to the second device in response to the content-downloading request. Accordingly, a user may support a download reservation and transmission by simply placing NFC-supporting devices in contact, support a queue download request and list management using NFC between network attached storage (NAS) and a smart device, and support a queue request and caching using a home network after establishing an NFC link.

Claims

1-20. -20. (canceled)

21. A content downloading method performed by a first device, wherein the content downloading method comprises steps of:

sending a content downloading request that requests content to be downloaded using a second device;

receiving confirmation that responds to the content downloading request from a device that has received the content downloading request;

receiving a wake-up request from the second device; and

receiving the content, downloaded to the second device, from the second device in response to the content downloading request,

wherein the first device receives the downloaded content by determining whether the downloaded content is able to be received based on predetermined reception condition information.

22. The content downloading method of claim 21, wherein the reception condition information of the downloaded content comprises at least any one of a power connection status condition, battery status condition, network status condition, and available storage space condition.

23. The content downloading method of claim 22, wherein the step of receiving the downloaded content comprises a step of determining whether the reception condition is satisfied by directly comparing the status of the first device with the reception condition information and receiving the downloaded content based on a result of the determination.

24. The content downloading method of claim 22, wherein the step of receiving the downloaded content comprises a step of:

determining, by the second device, whether the reception condition is satisfied by comparing the status of the first device with the reception condition information and receiving the downloaded content based on a result of the determination.

25. The content downloading method of claim 21, wherein at least any one of the content downloading request, the confirmation, and the wake-up request is transmitted and received using Near Field Communication (NFC).

26. The content downloading method of claim 21, wherein the step of receiving the wake-up request comprises at least one of steps of:

receiving the wake-up request through NFC; and

receiving the wake-up request through a Wireless Local Area Network (WLAN) or 3G/4G wireless communication.

27. The content downloading method of claim 21, wherein the content downloading request comprises downloading-related information, comprising source URI information of the downloading content, a downloading time indicative of an available downloading time, and wake-up time information indicative of a downloading start time.

28. The content downloading method of claim 21, wherein the step of sending the content downloading request comprises at least any one of steps of:

directly sending the content downloading request to the second device; and

sending the content downloading request to a third device.

29. The content downloading method of claim 28, wherein the third device is a device for relaying between a server related to a cloud service or the first device and the second device.

30. The content downloading method of claim 21, further comprising steps of:

displaying a user interface for selecting the content to be downloaded; and

selecting the content in response to a content selection signal,

wherein the step of sending the content downloading request comprises a step of automatically sending the content downloading request to the second device when the first device is connected to the second device based on the selection of the content.

31. The content downloading method of claim 21, further comprising steps of:

discovering accessible surrounding devices using a recently connected device list; and

obtaining a source URI of content to be downloaded from a content server.

32. A content downloading apparatus, comprising:

a transmission unit which sends a content downloading request that requests content to be downloaded using the second device; and

a reception unit which receives confirmation responding to the content downloading request, receives a wake-up request from the second device, and receives the content, downloaded to the second device, from the second device in response to the content downloading request,

wherein a first device receives the downloaded content by determining whether the downloaded content is able to be received based on predetermined reception condition information.

33. A content downloading method performed by a second device, wherein the content downloading method comprises steps of:

receiving a content downloading request from at least any one of a first device and a third device;

sending confirmation responding to the content downloading request;

downloading content to be downloaded based on the content downloading request;

sending a wake-up request to the first device; and

sending the downloaded content to the first device.

34. The content downloading method of claim 33, wherein the reception condition information of the downloaded content comprises at least any one of a power connection status condition, battery status condition, network status condition, and available storage space condition.

35. The content downloading method of claim 33, wherein whether or not to receive the downloaded content is determined by taking a size or capacity of the downloaded content.

36. The content downloading method of claim 33, wherein the reception condition information of the downloaded content comprises at least any one of a power connection status condition, a battery status condition, network status condition, and available storage space condition.

37. The content downloading method of claim 33, wherein the step of sending the wake-up request transmission comprises steps of:

sending the wake-up request through NFC; and

sending the wake-up request through a Wireless Local Area Network (WLAN) or 3G/4G wireless communication if a response to the wake-up request transmitted through NFC is not received from the first device for a reference time.

38. A content downloading apparatus, comprising:

a reception unit which receives a content downloading request from at least any one of a first device and a third device and downloads content from the first server based on the content downloading request; and

a transmission unit which sends confirmation responding to the content downloading request, sends a wake-up request to the first device, and sends the downloaded content to the first device,

wherein the downloaded content is transmitted by determining whether the downloaded content is able to be received based on reception condition information set by the first device.

39. A content downloading system, comprising:

a first device which sends a content downloading request that requests content to be downloaded using a second device, receives confirmation responding to the content downloading request, receives a wake-up request from the second device, and receives the content, downloaded to the second device, in response to the content downloading request; and

a second device which receives the content downloading request, sends the confirmation, downloads the content to be downloaded based on the content downloading request, sends the wake-up request to the first device, and sends the downloaded content to the first device,

wherein at least one of the first device and the second device receives or sends the downloaded content by determining whether the downloaded content is able to be received based on reception condition information set by the first device.

40. The content downloading system of claim 39, further comprising a third device which receives the content downloading request from the first device, sends the confirmation responding to the content downloading request to the first device, and sends the content downloading request to a second device.
