Abstract

The proposed invention provides a user-friendly way for people to turn a traditional in-progress voice-only telephone call into a multi-media call. This may be accomplished using various technologies that can be provided over the Internet or some other multi-media computing/networking platform. The multi-media aspect of the invention may be used to facilitate the sharing of additional information between the call participants as well as dynamically update security aspects (e.g., encryption keys) associated with call.

Claims

1. A method, comprising:

establishing a communication session between a plurality of participants for a first media type using a first application;

after initiation of and during the communication session, determining that a second media type different from the first media type is desired;

establishing a second communication channel for the second media type using a second application; and

associating the second communication channel with the communication session, wherein the second communication channel is associated with the communication session by creating a link to the second communication channel based on information associated with the communication session, the link being dynamically created and incorporating information unique to the communication session, the link being to one or more dynamically-created write-enabled web pages for editing or viewing by the participants.

2. The method of claim 1, wherein associating the second communication channel with the communication session comprises at least one of restricting access to the second communication channel to participants of the communication session, creating access restrictions to the second communication channel that are based on information associated with the communication session, and using the second communication channel to negotiate encryption keys for the communication session.

3. The method of claim 1, wherein the first media type is voice, wherein the second application comprises a web-based application and wherein the second media type comprises at least one of text, image, audio, and video.

4. The method of claim 3, wherein at least one communication session participant is enabled to add or modify information presented by the web-based application.

5. The method of claim 1, further comprising:

generating session information that is unique to the communication session during the step of establishing the communication session for the first media type;

forwarding the unique session information to participant endpoints of the communication session; and

using the unique session information to establish the second communication channel.

6. The method of claim 5, further comprising:

receiving a request to establish the second communication channel; and

creating a web page with the unique session information.

7. The method of claim 6, further comprising:

receiving a request to access the web page;

determining whether the request comprises the unique session information; and

determining access permissions to the web page based on the following logic;

(a) in the event that the request comprises unique session information that matches the unique session information used to create the web page, allowing access to the web page; and

(b) in the event that the request does not comprise unique session information that matches the unique session information used to create the web page, restricting access to the web page.

8. The method of claim 6, wherein the number of simultaneous logins allowed for the web page is limited to a number of participants engaged in the communication session.

9. The method of claim 1, wherein the communication session comprises a conference call between three or more participants.

10. A non-transitory computer readable medium comprising processor executable instructions that, when executed by a processor, are operable to perform the method of claim 1.

11. A communication system, comprising:

a non-transitory computer-readable storage medium comprising instructions stored thereon and a processor configured to execute the instructions, wherein the instructions stored on the computer-readable storage medium include;

a first application operable to support a first media type and establish a communication session between a plurality of participants using the first media type between at least two endpoints; and

a second application that is operable to establish a second communication channel, wherein the second communication channel supports a second media type that is different from the first media type, and wherein the second application is operable to associate the second communication channel with the communication session while the communication session is in progress, wherein the second communication channel is associated with the communication session by creating a link to the second communication channel based on information associated with the communication session, the link being dynamically created and incorporating information unique to the communication session, the link being to one or more dynamically-created write-enabled web pages for editing or viewing by the participants.

12. The system of claim 11, wherein the second application is operable to associate the second communication channel with the communication session by at least one of restricting access to the second communication channel to participants of the communication session, creating access restrictions to the second communication channel that are based on information associated with the communication session, and using the second communication channel to negotiate encryption keys for the communication session.

13. The system of claim 11, wherein the first media type is voice, wherein the second application comprises a web-based application and wherein the second media type comprises at least one of text, image, audio, and video.

14. The system of claim 13, wherein at least one communication session participant is enabled to add or modify information presented by the web-based application.

15. The system of claim 11, wherein the first application is further operable to generate session information that is unique to the communication session and forward the unique session information to participant endpoints of the communication session and wherein the second application is further operable to use the unique session information to establish the second communication channel.

16. The system of claim 15, wherein the second application is further operable to receive a request to establish the second communication channel, and create a web page with the unique session information.

17. The system of claim 16, wherein the second application is further operable to receive a request to access the web page, determine whether the request comprises the unique session information, and determine access permissions to the web page based on the following logic:

(a) in the event that the request comprises unique session information that matches the unique session information used to create the web page, allow access to the web page; and

(b) in the event that the request does not comprise unique session information that matches the unique session information used to create the web page, restrict access to the web page.

18. The system of claim 16, wherein the number of simultaneous logins allowed for the web page is limited to a number of participants engaged in the communication session.

19. The system of claim 16, wherein request comprises at least one of (i) an http GET request, (ii) an https GET request, and (iii) a predetermined sequence of DTMF tones.

20. The system of claim 11, wherein the communication session comprises a conference call between three or more participants.
