Problems solved by technology
[0008] In the 3GPP standard, the methods for reducing power consumption and optimizing transmission efficiency basically have two characteristics. The first is that the underlying hardware support of the terminal is required, and the implementation is complex; the second is that both the terminal and the network side have corresponding functional modules to implement. Support, however, these are functions that need to be promoted by standards organizations and supported by network operators, and the cost is very high

Embodiment Construction
[0080] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.
[0081] figure 1 It is a flowchart of a method for implementing data transmission in an embodiment of the present invention, figure 2 The method shown can be applied to the sending end such as the terminal side, such as figure 1 shown, including the following steps:
[0082] Step 100: Use a pre-obtained compression strategy to process the first data packet to be sent, and delete duplicate data specified by the compression strategy in the first data packet.
[0083] Among them, the compression strategy includes several rules, which are used to compare whether the data packe...

The invention discloses a data transmission method and device. The method includes: using a pre-acquired compression strategy to process a first data packet to be sent, and deleting duplicate data specified in the first data packet according to the compression strategy; processing The second data packet to be sent is generated after the first data packet to be sent, wherein the second data packet includes a modification record field for indicating that duplicate data is deleted according to the compression policy; the second data packet is sent to the receiving end. Through the method for realizing data transmission provided by the present invention, the repeatedly sent information in the data packets to be sent is deleted, and the amount of actually transmitted data is reduced. The method of the present invention does not need additional hardware support, and simply realizes the reduction of the amount of actually transmitted data, thereby saving costs.
Description
technical field [0001] The present invention relates to but not limited to the Internet of Things communication technology, especially a method and device for realizing data transmission. Background technique [0002] The Internet of Things (IoT, Internet of Things) is a major trend in the development of current communication technologies. In recent years, on the one hand, whether it is large-scale specification organizations such as the 3rd Generation Partnership Project (3GPP), or network operators and terminal manufacturers in various countries, they have begun to dig into the low-end to seek low-speed, low-bandwidth, and low-power consumption. technical direction. On the other hand, the Internet of Things has very strict requirements on terminal power consumption. Therefore, it is an important research direction to improve data transmission efficiency, reduce power consumption, and prolong battery life of terminal equipment. [0003] Furthermore, the data transmission...
