Problems solved by technology

[0004] Using the existing technology, the terminal device will not stop the repeated transmission of MSG3 until the preset sending time, resulting in a waste of communication resources between the terminal device and the network device, so that the terminal device sends data to the network device through EDT It takes a long time, which ultimately reduces the communication efficiency between the terminal device and the network device

Abstract

The invention provides a data transmission method, device and system, and the method comprises the steps that network equipment actively transmits information to terminal equipment after MSG3 transmitted by the terminal equipment obtains EDT data in the MSG3, thereby enabling the terminal equipment to stop the continuous repeated transmission of invalid MSG3 after the terminal equipment receives the information transmitted by the network equipment, and improving the transmission efficiency of the MSG3. Therefore, the time consumed for sending the data to the network equipment by the terminal equipment in the EDT mode is reduced, and the communication efficiency between the terminal equipment and the network equipment is improved.

Description

Technical field[0001]This application relates to the field of communication technology, and in particular to a data transmission method, device and system.Background technique[0002]The technical specifications of the third generation partnership project (3GPP) define early data transmission (EDT) technology. During the process of random access of terminal equipment to network equipment, the The incoming message carries the communication data sent to the network device, so as to further improve the communication efficiency between the terminal device and the network device.[0003]Specifically, in the prior art, the terminal device can carry EDT data in the third message (MSG3) in the random access process sent to the network device, so that the network device can receive the message sent by the terminal device in advance when receiving MSG3. The first data, because when the terminal device sends the first data to the network device at this time, it is in the process of the terminal de...
