The invention comprises a videoconference server () comprising: &#x2014;an audio processing module () configured to, &#x2218;calculating an average audio processing delay of processing audio packets intended to the second client device, in order that the second client device may synchronize a received video packet with the associated received audio packet, &#x2014;a video router () configured to: &#x2218;duplicate the video packet and temporarily store the duplicated video packet, &#x2218;receive a retrieving request from the second client device () for retrieving a lost video packet, &#x2218;retrieving the duplicated video packet associated with the identification information in the video buffer ().

Videoconference server, client device, videoconference system and method

A communication device comprising: a tag reader () configured to: &#x2014;read an identification tag signal () comprising an identification indication of a target communication device (), a discovery module () configured to: &#x2014;send a discovery request () to a registration service infrastructure (), comprising the identification indication, &#x2014;receive a discovery response () from the registration service infrastructure (), comprising network location information of the target communication device (), a session control module () configured to: &#x2014;send a shift request () to a home communication node () for shifting a communication session from the initial communication device to the target communication device (), wherein the home communication node () handles all communication sessions with the initial communication device, the shift request () comprising the network location information of the target communication device (), &#x2014;terminate the communication session with the remote communication device ().
