Embodiment Construction

[0023] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The present invention only adjusts the capacity of the aggregated frame according to the channel transmission quality in the existing frame aggregation control technology, which reduces the effectiveness and reliability of data transmission when the system adopts low-rate transmission, and cannot adapt to the multi-rate characteristics ...

Abstract

The invention provides a frame aggregation control method, a device and a system, wherein the method comprises the following steps of: obtaining channel transmission quality and system to-be-transmission speed, and obtaining the length of an aggregated frame to be transmitted according to the channel transmission quality and the system to-be-transmission speed. With the method, the device and the system provided by the invention, the length of the arrogated frame is controlled effectively, thus, the effectiveness and the reliability of data transmission are improved, and the multi-rate feature of a wireless local area network is supported.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a frame aggregation control method, device and system. Background technique [0002] In the wireless local area network, the user terminal accesses the network through the access point device. In order to improve the transmission rate of the wireless local area network and meet the user's requirements for high-speed wireless communication, IEEE 802.11n adopts the frame at the Media Access Control (MAC) layer. Aggregation technology, the MAC protocol supports two aggregation methods: MAC Service Data Unit aggregation (Aggregation Mac Service Data Unit, A-MSDU) and MAC protocol data unit aggregation (Aggregation MAC Protocol Data Unit, A-MPDU), figure 1 A schematic diagram of the aggregation structure of A-MSDU and A-MPDU, such as figure 1 As shown, it includes: A-MSDU aggregates multiple media access control service data units (Mac Service Data Unit, MSDU) together, shares a ...
