Problems solved by technology

And if the terminal device reselects an access network device every time it needs to transmit a small packet, then every time a small packet is transmitted, the access network device where it is located at this time needs to obtain the terminal device's information from the above-mentioned specific access network device. Context information, which will reduce the efficiency and speed of small packet transmission

Abstract

Disclosed are a data transmission method and device, the method comprising: receiving configuration information sent by a first access network device, the configuration information being used for configuring a terminal device to report indication information to a target access network device; and according to the configuration information, sending indication information to the target access network equipment, wherein the indication information comprises execution of context acquisition, or non-execution of context acquisition, or migration of the Relocation, or non-migration of the Relocation, or rapid completion of data transmission. Through the method, the data transmission efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data transmission method and device. Background technique [0002] Small Data Transmission (SDT) is a technology that can transmit data smaller than a certain data volume threshold when the terminal device is in the inactive state, and the terminal device does not need to enter the connected (Connected) state for data transmission , thereby saving certain network resources. [0003] Currently, when a terminal device transmits a small packet to an access network device, the access network device needs to acquire context (Context) information of the terminal device. Only a specific access network device has the context information of the terminal device. When the terminal device leaves the specific access network device and reselects to a new access network device, the new access network device needs to obtain information from the specific access network dev...
