Abstract

A system and method that facilitate efficient use of 3G high-speed data networks while providing for personalized audio content selection and coordinated distribution of selected content are disclosed. The invention categorizes audio content to be delivered over wireless networks such that the categories correspond to a different delivery priority. In an illustrative three-category implementation, category 1 content has the highest delivery priority for delivery as soon as possible, category 2 content has the next highest delivery priority for delivery, and category 3 content, such as music, audio books and so on, has the least urgent delivery priority. The categories are used to coordinate audio content delivery to efficiently use available bandwidth and network resources by delivering content at off-peak times. The invention also allows the downloading process to be interruptible such that it can be resumed at about the point of an interruption to conserve resources.

Claims

1. A method for delivering audio content comprising the steps of:

storing a request-playback file identifying audio segments to be sent to user equipment;

executing a request-playback for the audio segment;

determining a category for the audio segment from the request-playback file, wherein the category identifies a delivery priority for delivering the audio segment; and

delivering the audio segment to the user equipment in accordance with the determined category.

2. The method of claim 1 further comprising storing the audio segment.

3. The method of claim 2, wherein the category corresponds to one of urgent delivery priority, periodic delivery priority, no later than delivery priority and flexible delivery priority.

4. The method of claim 2, wherein for urgent delivery priority the audio segment is to be delivered in less than one hour.

5. The method of claim 2, wherein the step of delivering includes initiating and resuming delivery of the audio segment.

6. A method for providing audio content comprising:

classifying an audio segment into three or more categories, wherein each of the categories corresponds to a delivery priority for delivery of the audio segment;

assigning an identifier to the audio segment;

decomposing the audio segment into one or more audio files;

attaching descriptors to at least one of the audio segment and the audio file; and

sending the audio files for downloading over a wireless link.

7. The method of claim 6, wherein the audio segment is sent to a server.

8. The method of claim 6 further comprising receiving a request for a specified audio segment.

9. The method of claim 8, wherein the request comprises a time period during which the audio segment must be delivered, and an order in which the audio files must be delivered.

10. The method of claim 9, wherein the order specifies one of a preceding audio segment, a first audio segment, a last audio segment and a following audio segment.

11. The method of claim 6 further comprising

presenting a plurality of audio segments on at least one of a web-page, a printed page, over a voice telephone link, and via a cellular voice service connection;

and

receiving instructions selecting one or more of the audio segments.

12. The method of claim 11 further comprising:

creating a request-playback data file based on the selection and further received instructions; and

providing the request-playback data file to a server.

13. The method of claim 11 further comprising updating the plurality of audio segments.

14. The method of claim 12, wherein the request-playback data file includes an indicator to indicate whether an order of audio selection therein also specifies the order in which downloaded audio selections are to be played back.

15. The method of claim 6, wherein the step of sending occurs at one of the times:

immediately, periodically, during one of specified time intervals, during low usage of a wireless network, and in response to detecting availability of bandwidth.

16. The method of claim 6, wherein the step of sending comprises sending the audio files in two or more spaced apart time intervals.

17. The method of claim 6, wherein the step of sending comprises sending the audio files in response to successfully authenticating a user equipment to which the audio segment is being sent.

18. A method for providing audio content comprising:

receiving a selection of an audio segment at an audio content provider;

storing the selected audio segment at an intermediate node; and

sending the audio segment in accordance with a selected category to a user equipment, wherein the selected category is selected among three or more possible categories.

19. A system for providing audio content comprising:

means for presenting a plurality of audio segments;

means for authenticating the user equipment prior to downloading audio content to the user equipment;

a web server for storing audio segments selected at the means for presenting; and

means for sending a particular stored audio segment to a user equipment in accordance with a category associated with the particular stored audio segment.

20. A system of claim 19 further having a software agent for waking a sleeping client device, in response to successful authentication, from the web server.
