Method and device for realizing power saving mode of WLAN equipment

Abstract

The present invention relates to a method for implementing a power saving mode of a WLAN device, comprising: step 1, calculating the communication load c within a statistical time period; step 2, adjusting the parameter T of the power saving mode according to the communication load c, the parameter T increases with the increase of the communication load c; step 3, update the idle active time of the power saving mode to the parameter T. Combined with the interactive protocol of WLAN power-saving mode, through the statistics of communication load as feedback, the parameter values ​​in power-saving mode, such as idle active time, are dynamically adjusted to improve throughput and communication delay performance, while ensuring that power consumption does not increase significantly .

Description

technical field [0001] The invention relates to the field of wireless local area network (WLAN), in particular to a method and device for realizing a power-saving mode of WLAN equipment. Background technique [0002] For wireless devices, performance and power consumption are very important parameters, especially in handheld devices with a large amount of data transmission. In fact, there is a contradictory relationship between these two parameter indicators, and power consumption is often sacrificed while ensuring performance, and vice versa. The power-saving mode of the WLAN device has a certain impact on the performance due to the overhead of protocol interaction, especially in a long-distance or strong interference environment. In reality, the requirements for performance and power consumption are often dynamic. For example, it is desired to give priority to performance when performing communication services, and to give priority to power consumption during long-term st...

Problems solved by technology

[0006] If the T value is set relatively small and the interval of receiving data is greater than T, the STA will easily enter the dormant state again, and the data frame to be sent by the AP must be indicated by the TIM information of the beacon again, and wait for the STA to enter the active state before sending, which reduces the efficiency. Leading to a sudden drop in throughput performance or a large communication delay

[0007] If the T value is set relatively large, the STA must wait for a long time before entering sleep after receiving data each time, resulting in a longer time in the active state when the communication load is low, and the power consumption is greatly increased.
