Method and system for VoIP over WLAN to Bluetooth headset using ACL link and sniff for aligned eSCO transmission

A method in a wireless terminal, comprising:

• operating a first transceiver in a wireless PAN network for communicating first data units in accordance with a first communications protocol and operating in a wireless communications band;
• operating a second transceiver in a wireless LAN network for communicating second data units in accordance with a second communications protocol and operating in a band substantially the same as said wireless communications band;
• establishing with said first transceiver predefined slot times to listen for traffic for timing an assignment of relative priorities to the first data units and the second data units;
• assigning a higher priority to said second data units if one of said second data units is sensed during one of said predefined slot times, to abort transmission of one of said first data units;
• and
• assigning a higher priority to said aborted first data unit than to said second data units if one of said second data units is sensed while attempting to retransmit said aborted first data unit in a slot following said one of said predetermined slots, to retransmit said aborted first data unit.

A system, comprising:

• a wireless terminal;
• a wireless headset;
• a first transceiver in said wireless terminal operating in a wireless PAN network for communicating first data units in accordance with a first communications protocol and operating in a wireless communications band to communicate with said wireless headset;
• said first transceiver establishing predefined slot times to listen for traffic for timing an assignment of relative priorities to the first data units and the second data units;
• a wireless access point;
• a second transceiver in said wireless terminal operating in a wireless LAN network for communicating the second data units in accordance with a second communications protocol and operating in a band substantially the same as said wireless communications band to communicate with said wireless access point;
• and
• a controller in said wireless terminal coupled to said first and second transceivers, assigning a higher priority to said second data units if one of said second data units is sensed during one of said predefined slot times, to abort transmission of one of said first data units;
• said controller assigning a higher priority to said aborted first data unit than to said second data units if one of said second data units is sensed while attempting to retransmit said aborted first data unit in a slot following said one of said predetermined slots, to retransmit said aborted first data unit.

A chipset for a wireless terminal, comprising:
