Embodiment Construction

[0022] Aiming at the problem that the method of AP sending messages to low-speed STAs in the prior art cannot guarantee the video communication quality of low-speed STAs, the embodiment of the present invention provides a message sending method for low-speed STAs. The schematic diagram of the method is as follows figure 2 As shown in the figure, assume that STA1 and STA2 are high-speed STAs, and STA3 is a low-speed STA. If the AP needs to send multicast packets with different weights (H means high-weight packets, that is, high-weight frames are encapsulated in the packets; L means low-weight message, that is, the message encapsulates a low-weight frame), then the AP directly sends a multicast message to STA1 and STA2. In order to ensure the video communication quality of STA3, the high-weight message is sent in unicast mode. The packets are selectively discarded, that is, it is necessary to decide whether to send or discard according to the number of low-weight packets that ca...

Abstract

The invention discloses a method and device for sending low-speed STA (station) messages and an access device. The method comprises the steps of: for a low-speed STA, according to messages included in the determined current video streaming and selected parameters, determining the quantity of low-weight messages which can be sent by a current bandwidth; sequentially sending the messages included in the current video streaming; if messages to be sent are high-weight messages, sending the messages to be sent in a unicast mode, wherein if the weights of the packaged video frames in messages are more than or equal to a set value, the messages are the high-weight messages; and if the messages to be sent are low-weight messages, processing the messages to be sent according to the sequence of the messages to be sent in the low-weight messages included in the current video streaming and the determined quantity of the low-weight messages which can be sent by the current bandwidth. According to the scheme, because the high-weight messages can besuccessfully sent, the video communication quality of the low-speed STA can be ensured.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a message sending method, device and access equipment for low-speed stations (Station, STA). Background technique [0002] In multimedia communication, it is often necessary to encode video streams. Commonly used encoding standards include MPEG4, H264, etc. Using these standards to encode video streams can generate frames with different weights. For example, using MPEG4 encoding standards can generate I frames, P frame, B frame, I frame belongs to intraframe coding frame, P frame belongs to forward predictive coding frame, B frame belongs to bidirectional predictive interpolation coding frame, P frame depends on I frame to realize coding, B frame depends on P frame to realize To achieve encoding, the weight relationship of the three frames is I frame>P frame>B frame, I frame is a high weight frame, high weight frame is very important, if it is discarded, it will d...
