Method for transmitting downlink data in wireless network and wireless access equipment

Abstract

The invention discloses a method for transmitting downlink data in a wireless network and wireless access equipment. In the method, a wireless access point allocates corresponding queues for terminals of different types; and if the maximum transmitting rate supported by the terminals is higher, the corresponding queue capacity is larger. The message which needs downlink transmission is processed by the following steps: acquiring a destination terminal of message downlink transmission, and determining the queue corresponding to the destination terminal; and when the determined queue capacity is not full, putting the message into the determined queue. The message allocated into each queue is processed by the following steps: extracting the message from each queue in a first-in first-out mode, and downlink-transmitting the extracted message to the destination terminal in the current working frequency range. In a coexistent network environment of a high-speed terminal and a low-speed terminal, the existence of the low-speed terminal does not greatly influence the throughput rate of the high-speed terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a downlink data transmission method in a wireless network and a wireless access device. Background technique [0002] The International Institute of Electrical and Electronics Engineers IEEE (Institute of Electrical and Electronics Engineers) formulated the first version standard for wireless networks - IEEE 802.11 in 1997. Which defines the media access control layer (MAC layer) and the physical layer. The physical layer defines two spread-spectrum frequency modulation methods and one infrared transmission method working on the 2.4GHz ISM (industrial / scientific / medical) frequency band. The maximum transmission rate is designed to be 2Mbit / s. Communication between two devices can be performed in a device-to-device manner, or under the coordination of a base station or an access point. In order to obtain good communication quality in different communication environments, the ca...
