Abstract
The disclosure relates to a system, methods, devices and nodes for managing shared user content. The system comprises a wireless device which is operative to upload the content to be shared to a Content Delivery Network (CDN) Delivery and Caching Node (DCN), which in turn is operative to cache and deliver the shared user content to other wireless devices and network nodes. The system further comprises a CDN management node, operative to manage the storage of the shared user content in the CDN DCN and a network node operative to instruct the wireless device to store the shared user content to the CDN DCN and to retrieve the shared user content from the CDN DCN.
Claims16
A wireless device (WD) (10, 12, 14) for uploading a user content to be shared to a Content Delivery Network (CDN) Delivery and Caching Node (DCN) (20), the WD (10, 12, 14) comprising:
- a transmitter (410) operative to send a request to a network node (75) for a transfer of the user content to be shared from the WD (10, 12, 14);
- a receiver (420) operative to receive a Uniform Resource Locator (URL) from the network node (75) for the user content to be shared;
- a transmitter (410) being further operative to send the URL to the CDN DCN (20) and to upload the user content to be shared to the CDN DCN (20);
- and
- power supply circuitry (440) operative to supply power to the WD (10, 12, 14).
A Content Delivery Network (CDN) Delivery and Caching Node (DCN) (20) for caching and delivering a shared user content, the CDN DCN (20) comprising:
- a receiver (520) operative to receive a Uniform Resource Locator (URL) from a Wireless Device (WD) (10, 12, 14) for the shared user content;
- a transmitter (510) operative to send the URL to a CDN management node (50) for authentication;
- the receiver (520) being further operative to receive an authentication response from the CDN management node (50);
- the receiver (520) being further operative to receive the shared user content corresponding to the URL from the WD (10, 12, 14);
- a storage (560) operative to cache the shared user content;
- and
- power supply circuitry (540) operative to supply power to the CDN DCN (20).
A network node (75), operative to instruct a Wireless Device (WD) (10, 12, 14) to store a shared user content to a Content Delivery Network (CDN) Delivery and Caching Node (DCN) and to retrieve the shared user content from the CDN DCN (20), the network node (75) comprising:
- a receiver (620) operative to receive a request for a transfer of the shared user content from the WD (10, 12, 14);
- processing circuitry (630) operative to select a CDN DCN (20) for storing the shared user content;
- a transmitter (610) operative to send a Uniform Resource Locator (URL) for the shared user content to the (10, 12, 14) WD;
- and
- power supply circuitry (640) operative to supply power to the network node (75).
A Content Delivery Network (CDN) management node (50), operative to manage storage of shared user content in CDN Delivery and Caching Node (DCN), the CDN management node (50) comprising:
- a receiver (720) operative to receive a request for a Uniform Resource Locator (URL) from a network node (75);
- processing circuitry (730) operative to update information relating to an account associated with the network node (75);
- a transmitter (710) operative to send the URL to the network node (75);
- the receiver (720) being further operative to receive the URL from a CDN DCN (20);
- the processing circuitry (730) being further operative to authenticate the URL;
- and
- the transmitter (710) being further operative to send an authentication response to the CDN DCN (20), the authentication response including a time-to-live (TTL) for the shared user content.
