Abstract
There is provided, in a source device, a method for handing off a media session from the source device to a target device in a network. The target device is informed of an impending handoff of the media session. Session state information is transmitted to the target device in preparation for the handoff. The source device is authenticated with respect to a router that is common to both the source device and the target device, prior to the handoff. The conducting of the media session on the source device is ceased in place of the target device, subsequent to the handoff.

18. A system for handing off a media session across multiple devices in a network, comprising:
-
a source device for initially receiving session media corresponding to the media session;
a target device for receiving session state information from the source device in preparation for a handoff of the media session; and
a common router for initially providing the session media to the source device, for authenticating the source device and the target device with respect to the handoff, for receiving session related information from at least one of the source device and the target device, and for redirecting the session media to the target device, and wherein the target device conducts the media session in place of the source device, when the session media is redirected thereto. - View Dependent Claims (19, 20, 21)
