Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Aiming at the defects that the capacity of an aggregated frame is only adjusted according to the channel transmission quality in the prior frame aggregation control technology, the effectiveness and reliability of data transmission are reduced when a system adopts low-rate transmission, the multi-rate characteristic of a wireless local area network cannot be adapted, and the like, the invention provides a solution, namely the length of the aggregated frame to be transmitted is obtained according to the obtained channel transmission quality and the system to-be-transmitted rate, so that the effective control of the length of the aggregated frame in the high-speed wireless transmission of the wireless local area network is realized, the effectiveness and reliability of the data transmission are improved, and the multi-rate characteristic of the wireless local area network is supported.
Fig. 2 is a flowchart of an embodiment of a frame aggregation control method according to the present invention, as shown in fig. 2, the method includes:
in order to improve the transmission rate of the wireless local area network and meet the requirement of a user on high-speed wireless communication, when the channel transmission quality reaches a preset opening threshold, the channel at the moment is suitable for performing aggregation transmission on data frames, a frame aggregation control device starts a frame aggregation function, the data frames are aggregated and then transmitted by sending end equipment, and the data transmission efficiency is improved.
In the process of performing wireless data transmission by using a frame aggregation function, the channel transmission quality and the transmission rate of the system to be transmitted are constantly changed, so that the length of an aggregation frame affects the transmission performance of a wireless local area network:
on one hand, the actual wireless transmission environment is complex, the channel transmission quality is changed all the time, and under the scene of conflict or high error rate, if large data packet transmission is adopted, namely the length of an aggregation frame is long, the occupied channel time is long, repeated retransmission is triggered, and the system transmission efficiency is reduced on the contrary;
on the other hand, due to the multi-rate characteristic of the wireless local area network, the transmission rate of the system changes according to the specific application situation, if the system adopts a low-rate transmission large-capacity aggregation frame, the transmission efficiency is not obviously improved even if the capacity of the aggregation frame is larger, but the system can be switched from the low-rate transmission to a high-rate transmission, and the throughput of the system can be greatly reduced because the channel occupied by the previous low-rate transmission large-capacity aggregation frame is too long, and the high-rate transmission cannot be switched to the high-rate transmission immediately;
therefore, the frame aggregation control device needs to obtain the channel transmission quality and the rate to be transmitted of the system in real time, for example, the channel transmission quality and the rate to be transmitted of the system are obtained according to a preset period required by the application of the system, and the length of the aggregated frame is adjusted based on the channel transmission quality and the rate to be transmitted of the system.
