Abstract

A method for causing a calling client station to obtain content from a network server in response to a trigger signal received by the client during the ringback period for a call. The trigger signal is transmitted from a ringback server to a calling client station during the ringback period of call setup, whereby the trigger signal, once received and recognized by the calling client station, causes the station to request and obtain content from a network server. In another aspect, a method for providing content to a calling client station by transmitting a trigger signal to the calling client station during call setup, thereafter receiving at a network-based content server a request from the calling client station, generated in response to the trigger, for a content-download, and providing the content-download in response to the request.

Claims

1. A method of providing content to a client station comprising:

during setup of a call placed by the client station, transmitting a trigger to the client station within ringback provided to the client station during a ringback period for the call, wherein transmitting the trigger comprises transmitting the trigger in pieces interleaved within the ringback so as to ensure playout of at least a portion of the ringback before all of the pieces of the trigger are received by the client station; and

thereafter receiving from the client station a content-download request generated by the client station in response to the trigger, and providing the content to the client station in response to the content-download request,

wherein the trigger indicates a network address of a content server, and wherein receiving from the client station the content-download request comprises receiving a content-download request addressed to the content server at the network address.

2. The method of claim 1, wherein the content is related to ringback that is played out to the client station during the ringback period.

3. The method of claim 2, wherein the ringback played out to the client station during the ringback period is a portion of media, and the content comprises a more complete version of the media.

4. The method of claim 2, wherein the ringback played out to the client station during the ringback period is audio, and the content comprises video related to the audio.

6. The method of claim 1, wherein transmitting the trigger comprises transmitting the trigger during playout of ringback to the client station.

7. The method of claim 1, wherein the trigger comprises at least one of a human-audible tone and a digital parameter.

8. The method of claim 1, wherein providing the content to the client station comprises:

prompting a user of the client station for authorization to download the content, and then downloading the content upon receipt of user authorization.

9. The method of claim 1, wherein the content comprises at least one of (i) audio, (ii) video, (iii) program logic, and (iv) data usable by the client station to allow playout of other content that was stored on the client station before placement of the call.

5. A method of downloading content to a client station comprising:

during a ringback period of a call setup of a call placed by the client station, receiving into the client station a trigger transmitted from a network entity, wherein receiving the trigger during the ringback period comprises receiving the trigger just before playout of ringback to the client station; and

in response to the trigger, the client station downloading content that is distinct from the ringback,

wherein the trigger indicates a network address of a content server, and wherein downloading the content comprises downloading the content from the content server at the network address.

10. The method of claim 5, wherein downloading the content comprises downloading the content during the ringback period for the call.
