METHOD AND SYSTEM FOR DETERMINING THE EXISTENCE OF BROADCAST AND MULTICAST FRAMES BUFFERED IN AN ACCESS POINT |
摘要 |
A method and a system for determining the existence of broadcast/multicast frames buffered in an access point (AP) are used to avoid wakening a station (STA) unnecessarily. The method includes: when receiving broadcast/multicast frames sent from a service network and/or multicast group, an AP sets a broadcast/multicast indication bit that associates the service network and/or multicast group to the valid state and sends frames that carry the broadcast/multicast indication bit to a STA; the STA determines whether there are broadcast/multicast frames buffered in the AP according to the associated service network and/or multicast group and the received broadcast/multicast indication bit. Embodiments of the present disclosure also disclose an AP and a STA. The AP can identify whether there are broadcast/multicast frames buffered in an AP. |
