Abstract

A method performed at an apparatus includes receiving a request for media content corresponding to a user equipment; requesting and receiving some of the media content from a server; and if the requested media content should not be optimized, sending, through the network toward the user equipment, information that causes a node to direct additional requests from the user equipment for the media content through the network toward the server without passing through the apparatus. Another method includes receiving a redirect message comprising an indication corresponding to a location of media content and comprising a tag indicating the redirect message should cause a first apparatus to redirect requests from a user equipment for the media content to a server having the media content without passing through a second apparatus; and for requests received from the user equipment and corresponding to the indication, forwarding requests through the network toward the server.

Claims

1. A method, comprising:

receiving at an apparatus a request for media content, the request corresponding to a user equipment wirelessly connected to a base station in a wireless network;

requesting and receiving by the apparatus a portion of the media content from a media server; and

responsive to a determination the requested media content should not be optimized, sending, through the network toward the user equipment, by the apparatus information that causes a network node to direct additional requests from the user equipment for the media content through the network toward the media server without passing through the apparatus.

2. The method of claim 1, wherein the information comprises an address of the media server.

3. The method of claim 1, further comprising responsive to a determination the media content should be optimized, optimizing the portion of the media content to create optimized media content and sending the optimized media content to the user equipment.

4. The method of claim 3, wherein optimizing further comprises performing one or more of transcoding, transrating, or transsizing the portion of the media content to create the optimized media content.

5. The method of claim 1, further comprising determining whether the media content should be optimized.

6. The method of claim 5, wherein determining whether the media content should be optimized further comprises determining whether the media content should be optimized based at least on metadata corresponding to the media content.

7. The method of claim 6, wherein determining whether the media content should be transcoded based at least on metadata corresponding to the media content and provided by the media server comprises determining whether the media content should be transcoded based at least on the metadata and on one or more of congestion status of wireless network congestion corresponding to at least a wireless link from the base station to the user equipment, a device type of the user equipment, or one or more content policies.

8. The method of claim 1, wherein the information comprises a tag comprising at least a fixed part.

9. The method of claim 8, wherein the tag further comprises a variable part comprising a message authenticate code and a timestamp corresponding to the request for the media content, and wherein the method further comprises determining the message authenticate code using at least the timestamp, a key, and an indication corresponding to a location of the media content on a network.

10. The method of claim 1, performed by a media content optimizer.

11. A method, comprising:

receiving at a first apparatus in a network from a second apparatus in the network a redirect message comprising an indication corresponding to a location of media content on a network and comprising a tag indicating the redirect message should cause the first apparatus to redirect requests from a user equipment for the media content to a media server having the media content without passing through the second apparatus; and

for requests received from the user equipment and corresponding to the indication corresponding to the location of the media content on the network, forwarding associated requests through the network toward the media server.

12. The method of claim 11, wherein the tag is a first tag, wherein the requests comprise requests comprising a second tag, and wherein forwarding associated requests further comprises forwarding a portion of requests received from the user equipment and comprising the second tag toward the media server.

13. The method of claim 12, further comprising:

determining by the first apparatus the second tag; and

forwarding from the first apparatus to the user equipment the redirect message including the indication and the second tag.

14. The method of claim 12, wherein the requests received from the userequipment comprise requests not comprising the second tag, and wherein forwarding further comprises forwarding the requests not comprising the second tag toward the second apparatus.

15. The method of claim 12, wherein the requests comprising the second tag comprise the indication corresponding to the location of media content on the network, the second tag embedded in the indication, and forwarding further comprises stripping the second tag from the indication and forwarding the indication without the second tag toward the media server.

16. The method of claim 11, wherein forwarding further comprises forwarding requests toward the media server in response to the requests comprising second indications deemed to correspond to the indication in the redirect message.

17. The method of claim 16, further comprising forwarding requests toward the second apparatus in response to the requests comprising second indications deemed not to correspond to the indication in the redirect message.

18. The method of claim 16, wherein the redirect message is a first redirect message, and wherein the method further comprises sending in a second redirect message the indication but not the tag toward the user equipment through the network, wherein the requests comprising second indications are deemed to correspond to the indication in the first redirect message in response to the second indications matching the indication in the first redirect message.

19. The method of claim 11, wherein the indication comprises one of a uniform resource locator or a uniform resource identifier.

20. The method of claim 11, performed by a network node in an evolved packet core.
