Abstract

A method, system, and computer-readable media are provided for managing a handoff of a video session including a plurality of devices. The method can include monitoring a signal strength in a first access technology of a mobile device within a first video session. The method can additionally include detecting a change in the signal strength of the at least one mobile device and determining a second access technology for the mobile device. Moreover, the method can include establishing a second video session using the second access technology for the mobile device and the other devices within the first video session.

Claims (35)

1. A method of managing a handoff of a video session including a plurality of devices, comprising:

monitoring a signal strength in a first access technology of at least one mobile device within a first video session, the first video session including the at least one mobile device and one or more devices connected with the at least one mobile device;

determining whether the signal strength exceeds a pre-determined threshold decibel value;

determining whether the pre-determined threshold decibel value is exceeded for a pre-determined threshold amount of time;

detecting a change in the signal strength of the at least one mobile device where the signal strength exceeds the pre-determined threshold decibel value for the pre-determined threshold amount of time;

determining a second access technology for the at least one mobile device; and

establishing a second video session using the second access technology for the at least one mobile device and the one or more devices.

2. The method according to claim 1 , further comprising:

buffering the first video session; and

playing the buffered first video session within the second video session.

3. The method according to claim 2 , further comprising terminating the first video session after the first video session is buffered.

4. The method according to claim 1 , wherein detecting the change in the signal strength comprises detecting the signal strength exceeding a threshold decibel value for a threshold amount of time.

5. The method according to claim 1 , wherein the second access technology is different from the first access technology.

6. The method according to claim 1 , wherein the second access technology is the same as the first access technology.

7. The method according to claim 1 , further comprising allocating a space within a frequency spectrum for the second video session in order to transmit video information.

8. The method according to claim 7 , wherein allocating the space comprises modifying an amount of space of data information within the frequency spectrum.

9. The method according to claim 8 , wherein an entity modifying the amount of space of data information has to first authenticate itself with a router.

10. One or more tangible computer-readable media having computer-useable instructions embodied thereon for performing a method of managing a handoff of a video session including a plurality of devices, the method comprising:

identifying a communication channel;

identifying an access technology;

determining an amount of bandwidth within the communication channel for one or more first items of video information based on the access technology;

modifying one or more second items of data information within a frequency spectrum of the communication channel to allocate bandwidth for the one or more first items of video information within the communication channel; and

pushing the one or more first items of video information through the allocated bandwidth, wherein the one or more first items of video information includes a buffered video session.

11. The computer-readable media according to claim 10 , further comprising manipulating a router in order to prohibit unauthorized users from accessing the communication channel.

12. The computer-readable media according to claim 11 , further comprising authenticating a manipulator of the router before the router is manipulated.

13. The computer-readable media according to claim 10 , wherein the router is a base station controller.

14. The computer-readable media according to claim 10 , further comprising transcoding the one or more first items of video information to a codec based on access technologies of all devices within the video session.

15. A system for managing a handoff of a video session including a plurality of devices, comprising:

a mobility manager for detecting a change in a signal strength of at least one mobile device within a first video session, establishing a second video session using an access technology for the at least one mobile device and one or more devices connected with the at least one mobile device, and buffering the first video session, wherein detecting the change in the signal strength of the at least one mobile device comprises determining that the signal strength exceeds a pre-determined threshold decibel value and determining that the pre-determined threshold decibel value is exceeded for a pre-determined threshold amount of time; and

a resource manager for determining an amount of bandwidth within the communication channel for the second video session based on the access technology, and modifying data information within a frequency spectrum of the communication channel to allocate bandwidth for the second video session within the communication channel.

16. The system according to claim 15 , wherein the mobility manager pushes the buffered first video session through the allocated bandwidth within the channel.

17. The system according to claim 15 , wherein the resource manager transcodes one or more items of video information to a codec based on access technologies of all devices within the first video session.

18. The system according to claim 15 , wherein the mobility manager detects the change in the signal strength by detecting when the signal strength exceeds a threshold decibel value for a threshold amount of time.

19. The system according to claim 15 , wherein the mobility manager terminates the first video session after the first video session is buffered.

20. The system according to claim 15 , wherein the resource manger authenticates itself with a router in order to manipulate the router for locking-out unauthorized users of the communication channel.
