Abstract

A method for sending a wireless packet is described. A signal strength of a client is acquired. A priority queue to which the client belongs is set according to the signal strength of the client. A priority of a wireless packet to be sent to the client is set according to the priority queue so as to send the set wireless packet. In the meanwhile, a device for sending a wireless packet is also described. The disclosure can be utilized to put a wireless packet sent to a remote client (STA) having a weak signal into a low priority service queue and put a wireless packet sent to a close STA having a strong signal strength into a high priority service queue, so as to ensure data transmission of the close STA having a good signal and reduce the impact of the remote STA having a weak signal on the performance of the whole wireless network, thus improving reasonable allocation of wireless network resources and the Quality of Service (QoS) of the wireless network to further improve the satisfaction of user experience.

Claims

1. A method for sending a wireless packet, comprising:

acquiring a signal strength of a client, and setting, according to the signal strength of the client, a priority queue to which the client belongs;

setting, according to the priority queue, a priority of a wireless packet to be sent to the client;

sending the set wireless packet;

further comprising;

adjusting a Wireless MultiMedia (WMM) parameter of the priority queue according to a background noise of a wireless network environment;

accordingly, the sending the set wireless packet comprises;

sending the wireless packet according to the priority and a current WMM parameter of the priority queue.

2. The method for sending a wireless packet according to claim 1, wherein the acquiring the signal strength of the client comprises:

receiving a wireless packet sent by the client;

acquiring a current signal strength value of the client according to the received wireless packet;

accordingly, the setting, according to the signal strength of the client, the priority queue to which the client belongs comprises;

adjusting in real time, according to the current signal strength value of the client, a priority queue to which the client belongs currently.

3. The method for sending a wireless packet according to claim 2, wherein the wireless packet comprises:

an association request message, a management message, a control message and/or a data message sent by a client.

4. The method for sending a wireless packet according to claim 1, wherein the adjusting the WMM parameter of the priority queue according to the background noise of the wireless network environment comprises:

judging whether a background noise process is triggered, and when it is judged that the background noise process is triggered, acquiring a background noise in a current wireless environment;

adjusting the WMM parameter of the priority queue according to the acquired background noise.

5. A device for sending a wireless packet, comprising a wireless transceiver, and a processor, wherein the wireless transceiver is configured to acquire a signal strength of a client;

the processor is configured to set, according to the signal strength of the client, a priority queue to which the client belongs;

the wireless transceiver is also configured to set, according to the priority queue, a priority of a wireless packet to be sent to the client and send the set wireless packet;

further comprising a Wireless MultiMedia (WMM) parameter adjuster;

the WMM parameter adjuster is configured to adjust a WMM parameter of the priority queue according to a background noise of a wireless network environment;

accordingly, the wireless transceiver is configured to send the wireless packet according to the priority and a current WMM parameter of the priority queue.

6. The device for sending a wireless packet according to claim 5, wherein the wireless transceiver

is also configured to receive a wireless packet sent by the client and

acquire, according to the received wireless packet, a current signal strength value of the client;

accordingly, the processor is configured to adjust in real time, according to the current signal strength value of the client, a priority queue to which the client belongs currently.

7. The device for sending a wireless packet according to claim 5, wherein the WMM parameter adjuster

is also configured to generate a trigger signal of a background noise process,

acquire a background noise in a current wireless environment according to the trigger signal of the background noise process,

and adjust the WMM parameter of the priority queue according to the acquired background noise.
