Abstract

The invention discloses a data transmission method and device. The method comprises the steps that a core network device determines to switch data of a terminal device from a control plane to a user plane for transmission; and the core network device sends first indication information to the terminal device, the first indication information being used for indicating the terminal device to stop transmitting uplink data through a control plane, or the first indication information being used for indicating the terminal device to stop transmitting uplink data.

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] In a wireless communication system, data can be transmitted in two data transmission modes: a user plane transmission mode and a control plane transmission mode. The control plane transmission method can be used to transmit data packets with a small amount of data (such as a data packet of about 20 bytes, hereinafter referred to as small packet data), while the user plane transmission method is suitable for transmitting data packets with a large amount of data (such as 200 bytes) Bytes and above data packets, hereinafter referred to as large packet data). During the data packet transmission process, the transmission mode can be switched according to the actual situation. For example, assuming that the terminal device is currently using the control plane transmission scheme to transmit smal...
