Problems solved by technology

For this method, although the wireless underlying status can be known, the throughput performance of the entire wireless network is greatly sacrificed, and the bus between the CPU and the wireless chip is also very likely to compete with other processes, making the above control invalid

Embodiment 1

[0029] Embodiment 1 of the present invention provides a method for determining the wireless transmission status, the steps of the method are as follows figure 1 shown, including:

[0030] Step 101, monitor the signal.

[0031] In this embodiment, the wireless chip, such as the channel idle Rx_clear signal provided inside the 802.11 wireless chip, and the Tx_frame signal transmitted by the network card can be used to determine the underlying wireless state. Therefore, in this step, the Rx_clear signal and the Tx_frame signal provided by the wireless chip can be monitored for subsequent operations.

[0032] Step 102, making a logical judgment.

[0033] Only based on the Rx_clear signal and Tx_frame signal, the wireless transmission status of the wireless chip cannot be directly known. In this step, a logical judgment can be made based on the monitored Rx_clear signal and Tx_frame signal, so as to determine the wireless status of the wireless chip. send status.

Embodiment 2

[0050] Embodiment 2 of the present invention provides a device for determining the state of wireless transmission, the structure of which is as follows image 3 shown, including:

[0051] The monitoring module 11 is used to monitor the channel idle Rx_clear signal provided by the wireless chip and the network card to transmit the Tx_frame signal;

[0052] The state determining module 12 is used to make a logical judgment according to the Rx_clear signal and the Tx_frame signal monitored by the monitoring module, and determine the wireless transmission state of the wireless chip according to the logical judgment result.

[0053] When the wireless chip detects that there is co-channel power transmission in the space, set the Rx_clear signal to low level, otherwise set Rx_clear to high level, and when the wireless chip sends a message, set Tx_frame to High level, otherwise set Tx_frame to low level;

[0054] The state determination module 12 is specifically used to trigger the ...

Embodiment 3

[0061] Embodiment 2 of the present invention provides a wireless access point, which may include the device described in Embodiment 2. Specifically, the structure of the wireless access point provided in Embodiment 3 may be as follows Figure 4 As shown, it includes a central processing unit 21, a wireless chip 22, a device 23 for determining the wireless transmission status, and a smart antenna 24:

[0062] Among them, the central processing unit 21 (CPU) determines the sending queue of the message, delivers the sending queue information to the wireless chip 22, and notifies the device 23 for determining the wireless sending status of the sending queue information. The wireless chip 22 outputs a radio frequency signal to the smart antenna 24 for transmission, and provides the Rx_clear signal and the Tx_frame signal to the device 23 for determining the wireless transmission state. The device 23 for determining the wireless transmission state judges the wireless transmission st...

Abstract

The embodiment of the invention provides a method for determining a wireless sending state, a device and a wireless access point; the method comprises the following steps that: logic judgment is carried out according to an Rx_clear signal and a Tx_frame signal provided by a wireless chip, so that the wireless sending state of the wireless chip is determined according to a logic judgment result, complicated chip research and development or signal sampling, reduction and encoding do not need to be carried out; consequently, high-difficulty data processing is prevented, calculation time delay is reduced, and compared with a method for forwarding a message to the wireless chip by rewriting a central processing unit (CPU), the throughput performance of a wireless network is prevented from being reduced, bus competition is prevented, and the controllability in determining the wireless sending state is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and wireless access point for determining a wireless transmission state. Background technique [0002] In wireless local area network applications, due to the influence of the propagation environment, wireless communication often does not achieve the desired effect. In order to solve this problem, smart antenna technology is often used in engineering to enhance the wireless access point (AP, Access Point) and client. Signal strength between wireless network cards (STA, Station), thereby improving communication quality. [0003] In the current AP technical solution, a central processing unit (CPU) and an 802.11 wireless chip are usually used for cooperative design, and the wireless bottom layer negotiation and transmission are completed by the wireless chip. The wireless medium layer information obtained by the upper layer usually lags behind the c...
