The embodiment of the invention discloses a data transmission method and device, equipment and a storage medium. The method comprises: acquring an application data packet to be transmitted in a targetapplication; transmitting the application data packet to first routing equipment through a first network data channel, and transmitting the application data packet to a proxy server by the first routing equipment; meanwhile, transmitting the application data packet to second routing equipment through a second network data channel, and transmitting the application data packet to a proxy server through the second routing equipment, wherein the second network data channel is a short-distance wireless data channel, and the first network data channel is different from the second network data channel; finally, transmitting the application data packet to the application server based on the deduplication mechanism through the proxy server. According to the method, short-distance wireless data isused as an auxiliary channel for data transmission, so that the stability of data transmission between the terminal equipment and the application server is improved, and the air interface packet lossrate and the data delay are effectively reduced.

The embodiments of the present application disclose a data transmission method, device, device, and storage medium. The method includes: acquiring an application data packet to be transmitted in a target application; and transmitting the application data packet to a first router through a first network data channel device, and the first routing device transmits the application data packet to the proxy server; at the same time, the application data packet is transmitted to the second routing device through the second network data channel, and the application data packet is transmitted by the second routing device. The packet is transmitted to the proxy server; the second network data channel is a short-distance wireless data channel, and the first network data channel is different from the second network data channel; finally, the application data packet is transmitted to the application server through the proxy server based on the deduplication mechanism. The method uses short-distance wireless data as an auxiliary channel for data transmission, improves the stability of data transmission between the terminal device and the application server, and effectively reduces the air interface packet loss rate and data delay.

The invention discloses a radio transmission power control method and a radio transmission power control device. The method comprises the following steps of acquiring radio transmitting power Pti, radio receiving power Pri, interference signal power Iti of a transmitting end, interference signal power Iri of a receiving end and a standard deviation J of shadow fading at the moment ti; obtaining asignal interference ratio Wti of the sending end and a signal interference ratio Wri of the receiving end according to Pti, Pri, Iti, Iri and J; respectively comparing the Wti and the Wri with the signal-to-interference ratio gate limit u; if Wti or / and Wri is / are smaller than u, adjusting the current radio transmitting power of the wireless access point AP, so that the signal interference ratio of the transmitting end to the receiving end is not smaller than u; judging whether the adjusted radio transmitting power Pti'is greater than the minimum power received by other STAs in the current local area network or not, and if so, taking the Pti 'as the radio transmitting power in the transmission time slot of the ti moment by the wireless access point AP; and if not, keeping the radio transmitting power of the wireless access point AP unchanged. According to the invention, radio transmission power self-adaptive control is realized.

The invention provides a data transmission quality management and control system and method. The system operates in a wireless access node. The wireless access node is connected with a transmitting end and a receiving end through a wireless network. The system detects the load type of currently transmitted data flow and current transmission parameters and judges whether the current transmission parameters are greater than or equal to standard transmission parameters. When the current transmission parameters are greater than or equal to the standard transmission parameters, the wireless access node continuously receives the data flow transmitted by the transmitting end or transmits the data flow to the receiving end. When the current transmission parameters are less than the standard transmission parameters of the receiving end, a message indicating failure of data flow transmission and a message indicating improving the transmission quality are transmitted to the receiving end.

The invention discloses a method and device for adjusting a spreading factor in a wide area Internet of Things, and relates to the technical field of Internet of Things communications for dynamicallyadjusting the spreading factor according to the current network environment, thereby reducing service delay and increasing service life of terminal batteries. The method comprises the following steps:setting the value of the spreading factor to a first preset initial value before transmitting the service; before transmitting the ith service, acquiring a signal-to-noise ratio SNR of the i-1th service and a SNR of the i-2th service reported by the terminal, and the current value of the spreading factor; determining the value of the spreading factor in the ith service according to the differencebetween the SNR of the i-1th service and the SNR of the i-2th service, and the current value of the spreading factor, wherein the value of i is an integer greater than or equal to 2; and sending thevalue of the spreading factor in the ith service to the terminal and the gateway to enable the terminal and the gateway to adjust the current value of the spreading factor to the value of the spreading factor in the ith service.
