However, in view of the complexity of the wireless transmission environment, it is not suitable to transmit long data packets in any case, because if the packet loss and retransmission are too frequent, the throughput of the system will also drop sharply

Embodiment 1

[0042] Such as Figure 4 Shown is Embodiment 1 according to the packet loss rate of the present invention.

[0043] When the wireless local area network device sends a data packet, it can confirm whether the data packet is successfully sent by receiving the confirmation frame sent by the other party. Therefore, the sending end can count the packet loss rate for a period of time, and the quality of the current wireless transmission environment can be measured according to the packet loss rate. When the packet loss rate is high, it is not suitable to send longer data packets, the length of the aggregated frame can be reduced or even the frame aggregation function is turned off; when the packet loss rate is low, the length of the data packet can be appropriately increased to increase the throughput, that is, if If the frame aggregation function is not enabled currently, enable the frame aggregation function, and if it is enabled, increase the length of the aggregation frame.

Abstract

The invention provides a frame aggregation control method of a WLAN (Wireless Local Area Network). The method comprises the following steps of: acquiring the quality of a current wireless transmission environment by a transmitting end; and judging whether to start the frame aggregation function or not according to the quality of the wireless transmission environment. The invention also provides a frame aggregation control device of the WLAN. The method and the device of the invention can flexibly adjust whether to start the frame aggregation function or not according to the conditions of the wireless environment where WLAN equipment is arranged, thereby improving the data transmission reliability.

Description

technical field [0001] The invention relates to a wireless local area network, in particular to a wireless local area network frame aggregation control method and device. Background technique [0002] Such as figure 1 As shown, in a wireless local area network, a terminal (mobile terminal or computer) accesses the network through an access point device. The wireless local area network technology based on IEEE802.11 series norms is a relatively important and widely used technology in the home network interconnection technology. However, the throughput and quality of service of the traditional wireless local area network are still lacking, and cannot well meet the requirements of multi-play services. In order to improve the throughput and performance of WLAN, IEEE802.11 established the TGn working group in 2004 to study a new generation of ultra-high-speed WLAN technology. IEEE802.11n is about to be completed and is expected to be released in mid-2009. IEEE802.11n carries ...
