Title (EN) VOICE SYNCHRONIZATION DURING CALL HANDOFF
(FR) SYNCHRONISATION VOCALE DURANT UN TRANSFERT D'APPEL
Abstract: front page image
(EN)A method, mobile electronic device and system for synchronizing hand-off of a voice media session between a WAN/cellular network and a WLAN network. When a hand-off occurs, the connection with both networks is temporarily maintained and the voice data on both connections compared to determine differences in the delays experienced over both connections. The timing of one or both voice streams is adjusted to synchronize the voice streams, and then the handoff is completed.
(FR)L'invention concerne un procédé, un dispositif électronique mobile et un système permettant la synchronisation de transfert d'une session média vocale entre un réseau WAN/cellulaire et un réseau WLAN. Lorsqu'a lieu un transfert, la connexion avec les deux réseaux est maintenue temporairement et les données vocales sur les deux connexions sont comparées pour déterminer des différences dans les retards subis sur les deux connexions. La synchronisation d'un flux vocal ou des deux flux vocaux est ajustée afin de synchroniser ces flux vocaux puis le transfert est effectué.
