Patent ID: 7885217

Claim:
A method comprising: determining by a wireless device whether a non-unicast message is to be transmitted by the wireless device by checking a Delivery Traffic Indicator Map (DTIM) Interval and a Listening Interval, the DTIM Interval representing a time period between successive checks by a wireless receiving device for non-unicast messages and the Listening interval representing a time period between successive checks by the wireless receiving device for unicast messages; and converting the non-unicast message into one or more unicast messages for transmission upon determining that the DTIM Interval is greater than the Listening Interval while the wireless device maintains an ability to check for and receive non-unicast messages in accordance with the DTIM Interval, wherein the DTIM Interval is set to be greater than the Listening Interval so that the wireless receiving device is checking for unicast messages more frequently than non-unicast messages.
