In the prior art, a single terminal adjusts a transmission queue according to a service, or controls a contention window through a wireless Access Point (AP) and cannot cooperate with other devices to adjust, so that collision among the devices is avoided when the same device simultaneously transmits uplink data.

Optionally, the first device and the N other devices are devices transmitting messages under the same network. For example, a plurality of devices periodically transmitting audio and video data in an 802.11e network.
Alternatively, the value of N may be flexibly set based on the actual scenario, for example, 3 terminal devices in the same network as the first device may be determined as other devices.
Optionally, the query packet may carry a first packet loss rate of the first device, a priority used for currently sending the uplink data packet, an IP address of the first device, a signal transmission strength (signal transmission strength may be RSSI), and so on.

As shown in fig. 4, the present embodiment includes the steps of:
s401, when the device 1 sends an uplink message, high priority sending (audio VO, video VI) is used by default according to an EDCA mechanism;
s402, the device 1 detects whether the packet loss rate is higher than a threshold value;
s403, when the device 1 detects that the packet loss rate is higher than a threshold value, and the audio and video are blocked, a query message is sent to query whether other devices are sending messages, and at the moment, a multicast message is sent, and all the devices can receive the multicast message; the inquiry message contains the IP address, packet loss rate, received signal strength indication (Received Signal Strength Indication, RSSI for short) and priority of the equipment 1;
S404, after receiving the inquiry message, if the inquiry message is currently transmitted, the device 2 detects the packet loss rate and the RSSI of the device, and if the inquiry message is better than the device 1, the device 1 replies the inquiry message, wherein the inquiry message comprises an IP address, the packet loss rate, the RSSI and the priority of the transmitted message;
s405, after receiving the inquiry message, if the inquiry message is currently being sent, the device 3 detects the packet loss rate and the RSSI of the device, and if the inquiry message is better than the device 1, the device 1 replies the inquiry message, wherein the inquiry message comprises an IP address, the packet loss rate, the RSSI and the priority of the sent message;
s406, the device 1 processes the reply messages of the device 2 and the device 3, and sequentially requests the device 2 and the device 3 to reduce priority transmission according to the packet loss rate sequencing until the packet loss rate sent by the device itself is normal;
s407, after receiving the request message for lowering the priority, the device 2 tries to lower the transmission, and detects whether the packet loss rate is normal or not, if so, the transmission is degraded, otherwise, the transmission is not lowered, and the lowering result of the device 1 is timely replied;
s408, after receiving the request message of lowering priority, the device 3 tries to lower the transmission, and detects whether the packet loss rate is normal or not, if so, the transmission is degraded, otherwise, the transmission is not lowered, and the lowering result of the device 1 is timely replied;
S409, if all terminals are polled once, the packet loss rate of the equipment 1 is not satisfied, the equipment 1 reduces the priority to send, and the above operation is repeated until the priority is reduced to the BE lowest priority);
and S410, recovering the highest priority after the equipment transmission is finished, and ensuring that the highest priority is used for starting transmission and is reduced in cooperation with other equipment in the transmission process.
In summary, the terminal collaboration mechanism is adopted in the embodiment, so that the problem of competition between the same devices can be solved; and interaction among the terminal devices does not need unified management of the AP, and the problem of reduction of the competition window mainly of the uplink service is effectively solved.
