发明名称 VOICE SYNCHRONIZATION DURING CALL HANDOFF
摘要 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.
