Abstract:
1. A method for determining the existence of broadcast frames buffered in an Access Point (AP), comprising: setting, by the AP, when receiving broadcast frames from at least one of a service network associated with a Station (STA) and a multicast group, which the STA joins, an index value that associates broadcast/multicast indication bits related to at least one of the service network or the multicast group and sending the frames carrying the broadcast/multicast indication bits to the STA, wherein the index value provides location information of the broadcast/multicast indication bits, wherein the broadcast/multicast indication bits are used for determining whether there are broadcast/multicast frames from at least one of the service network associated with a Station (STA) and the multicast group, which the STA joins, buffered in the AP, and setting a delivery traffic indication (DTIM) time that associates the service network or multicast group according to the broadcast frames and sending frames that carry the DTIM time to the STA, so that the STA can wake up according to at least one of the service network and the multicast group, the received broadcast/multicast indication bit, and the DTIM time; and receive the broadcast frames buffered in the AP.
