Abstract

A communications system serves as a proxy for a user device in a communications network. The communications system includes a network gateway that receives content in response to a user initiated content utilization attempt from a user device. A computer receives the content from the network gateway and, in response to receiving the content, determines whether the content utilization by the user can be permitted. The computer can also determine whether the content utilization by the user can be completed.

9. The communications system of claim 2,

wherein the communications system retrieves information associated with the ID, the information being used to determine whether the content utilization is permitted.

10. The communications system of claim 3,

wherein the information includes license data.

11. The communications system of claim 3,

wherein the information includes business rules data.

12. The communications system of claim 4,

wherein a response to the query includes information used to determine whether the content utilization is permitted.

13. The communications system of claim 5,

wherein the computer receives information associated with the ID, the information being used to determine whether the content utilization can be completed.

14. The communications system of claim 6,

wherein the information includes capability information describing capabilities of the first end user device.

15. The communications system of claim 9,

wherein the communications system determines whether an owner of the content has permitted the content utilization.

16. The communications system of claim 12,

wherein if the content utilization is permitted, the communications system determines whether the content utilization can be completed.

17. A method for determining whether a first end user device is permitted to receive content from a second end user device via a communications network, the communications network adapted to communicate with a content distribution system or a digital rights management system, the method comprising:

receiving, at a proxy, the content from the second end user device via a network gateway of a communications service provider in response to a user initiated attempt to utilize the content at the first end user device, wherein the proxy serves as a proxy for at least one other end user device that may also attempt to utilize the content; and

determining, at the proxy, from the received content, whether a format of the content is supported by the first end user device, and whether content utilization by the first end user device is permitted;

wherein the content is distributed from the proxy to the first end user device without contacting the content distribution system or the digital rights management system, if the proxy determines that both the format of the content is supported by the first end user device and content utilization by the first end user device is permitted.

18. The method of claim 17,

wherein the determining is based upon an ID provided with the content.

19. The method of claim 17, further comprising:

in response to receiving the content at the proxy, querying a digital rights manager that stores digital rights management information related to the content.
