ABSTRACT:
The invention solves the problem of reducing interference in simultaneous wireless LAN (WLAN) and Bluetooth signal handling, especially in voice over IP communications via a WLAN telephone to a Bluetooth headset. The invention sets up a voice link between the terminal and the headset by establishing sniff anchor points in the ACL link for assigning relative priorities to the WLAN and Bluetooth ACL packet traffic. A higher priority is assigned to WLAN packet traffic when it collides with original Bluetooth ACL packet traffic during a sniff anchor point. Thereafter, a higher priority is assigned to the terminal's retransmission of aborted Bluetooth ACL packets and the headset's response ACL packets in available Bluetooth slots following the anchor point.
