Abstract:
Presented herein are methodologies for handling multicast traffic that is transmitted to mobile devices in a given basic service set (BSS). The methodology includes detecting membership of clients in an Internet Protocol (IP) multicast group in a basic service set of a wireless network; determining whether the IP multicast group and its associated multicast traffic meet predetermined criteria; when the IP multicast group and its associated multicast traffic meet the predetermined criteria, negotiating with each client in the IP multicast group to have a target wake time (TWT) that includes, at least, a coincident overlap window of sufficient duration to transmit the multicast traffic associated with the IP multicast group; and transmitting the multicast traffic associated with the IP multicast group during the coincident overlap window, wherein the coincident overlap window is different from a delivery traffic indication message (DTIM) service period.
