Method and apparatus for controlling data transmission, and storage medium

A method for controlling data transmission, comprising:

• sending, by a network device, configuration information of small data transmission (SDT) to a terminal, wherein the configuration information of the SDT comprises configuration information of a bearer of the SDT;
• and
• when the terminal is in an idle state or an inactive state, receiving first information which is sent by the terminal when the terminal determines that first data is to be sent and that the configuration information of the SDT does not meet a transmission requirement of the first data, wherein the first information indicates that there exists the first data to be sent at the terminal and a bearer of the first data is not the bearer of the SDT;
• wherein the terminal determines that the configuration information of the SDT does not meet the transmission requirement of the first data comprises:
• the bearer of the first data is not the bearer of the SDT;
• wherein the configuration information of the bearer of the SDT comprises an identifier of the bearer of the SDT, and the bearer of the first data is not the bearer of the SDT comprises:
• an identifier of the bearer of the first data is different from the identifier of the bearer of the SDT.

An apparatus for controlling data transmission, comprising a memory, a transceiver and a processor:

• wherein the memory is configured to store a computer program;
• the transceiver is configured to send and receive data under control of the processor;
• the processor is configured to read the computer program in the memory and execute the following operations:
• receiving configuration information of small data transmission (SDT) from a network device, wherein the configuration information of the SDT comprises configuration information of a bearer of the SDT;
• when a terminal is in an idle state or an inactive state, and when the terminal determines that first data is to be sent, and determines that the configuration information of the SDT does not meet a transmission requirement of the first data, then sending first information to the network device, wherein the first information indicates that there exists the first data to be sent at the terminal and a bearer of the first data is not the bearer of the SDT;
• wherein the determining that the configuration information of the SDT does not meet the transmission requirement of the first data comprises:
• determining that the bearer of the first data is not the bearer of the SDT according to the configuration information of the bearer of the SDT;
• wherein the configuration information of the bearer of the SDT comprises an identifier of the bearer of the SDT, and the determining that the bearer of the first data is not the bearer of the SDT according to the configuration information of the bearer of the SDT comprises:
• determining, according to the identifier of the bearer of the SDT, whether an identifier of the bearer of the first data is the same as the identifier of the bearer of the SDT, and
• when the identifier of the bearer of the first data is different from the identifier of the bearer of the SDT, determining that the bearer of the first data is not the bearer of the SDT.
