Embodiment Construction

[0059]In the embodiment of the present invention, the data sending end obtains the first original data packet to be sent, compares the difference data of the first original data packet with respect to the preset reference data packet, and determines the difference amount of the difference data; When the difference amount of the difference data exceeds a preset threshold, the first original data packet is sent; otherwise, the difference data is generated into a difference data packet according to a preset grouping rule, and the difference data packet is sent. The data receiving end receives the first received data packet sent by the data sending end; when determining that the first received data packet is a difference data packet according to a preset judgment rule, according to the preset reference data packet and the first received data packet, using The data restoration rule restores the first received data packet to the first original data packet.

Abstract

The invention discloses a data transmission method, which comprises the following steps that: a data sending end acquires a first original data packet to be sent, compares difference data between thefirst original data packet and a preset reference data packet, and determines the difference quantity of the difference data; when the difference value exceeds a preset threshold value, the first original data packet is sent; and when the difference quantity does not exceed a preset threshold, a difference data packet is generated from the difference data according to a preset packaging rule, andhe difference data packet is sent. The data receiving end receives a first receiving data packet sent by the data sending end; and when determining that the first received data packet is a differencedata packet according to a preset judgment rule, the first received data packet is restored into a first original data packet by adopting a data restoration rule according to a preset reference data packet and the first received data packet. The invention further discloses a data transmission device and a storage medium.

Description

technical field [0001] The invention relates to the Internet of Things transmission technology, in particular to a data transmission method and device. Background technique [0002] The requirements of the Internet of Things for devices in the network mainly include the requirement of long standby time. For data terminals, the most important job is the uplink and downlink data transmission; the existing protocols of the Internet of Things have a series of methods to prolong the terminal standby, including the non-access stratum (NAS, Non-Access Stratum) signaling Carry data packets for transmission, limit bandwidth and traffic, and put the device into low-power shutdown mode during the time when there is no data transmission. However, there is no targeted and universal optimization method for the Internet of Things in terms of the transmission mode and the transmission protocol, especially the transmission protocol above the Internet Protocol (IP, Internet Protocol) layer. ...
