Problems solved by technology

Although the DTIM period can be reduced to lower latency, the side effect may be increased power consumption and reduced battery life for all connected client devices as these client devices need to wake up more frequently to receive broadcast and multicast frames

Embodiment Construction

[0025] In various implementations according to the present disclosure, the AP / SoftAP may check whether the current broadcast frame is destined for any client devices in the BSS associated with the AP / SoftAP that are not in power saving mode. In addition, the AP / SoftAP can check whether the current multicast frame is destined for any client device or any group of client devices in the BSS that are not in power saving mode. In the event that the AP / SoftAP recognizes that any client device or group of client devices is not in power save mode and that the broadcast or multicast frame is destined for any client device or group of client devices, the AP / SoftAP may send The broadcast or multicast frame is to such a client device or group of client devices without buffering the broadcast / multicast frame until a subsequent DTIM period.

[0026] Since the various embodiments of the present disclosure do not require special hardware, they are fully compatible with current and traditional...

Abstract

The embodiment of the invention discloses a method and a device for optimizing broadcast and multicast frame transmission. The method comprises the following steps: a communication device receives a broadcast or multicast frame after a first transmission flow indication map, wherein the communication device is associated with a basic service set; and the communication device sends the broadcast ormulticast frame to a first client device in the basic service set, instead of buffering the broadcast or multicast frame for transmission in a second transmission traffic indication map, wherein thesecond transmission traffic indication map follows the first transmission traffic indication map while the second client device in the basic service set is in a power saving mode. The embodiment of the invention can reduce the transmission delay of the broadcast / multicast frame.

Description

technical field [0001] The present invention relates to computing networks, and more particularly to a method and apparatus for optimizing broadcast and multicast frame delivery. Background technique [0002] According to the IEEE (the Institute of Electrical and Electronics Engineers) 802.11 specification, if any client device in the BSS (Basic Service Set, Basic Service Set) is in energy-saving mode, the AP (Access Point, Access Point) in the BSS or SoftAP (software-enabled AP, software-enabled AP) will buffer broadcast and multicast transmitted data frames, and the transmission of the buffered frames occurs at the DTIM (DeliveryTraffic Indication Map, transmission traffic indication map) beacon, instead of Consider that one or more other client devices in the BSS are not in power saving mode. However, there may be situations where some broadcast and / or multicast frames destined for client devices (or groups of client devices) in the BSS that are not in power-saving mode ...
