摘要：
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.
