Data transmission method by pre-configured resource, terminal device, and non-transitory computer-readable storage medium

A terminal device, comprising:

• a memory and a processor;
• wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to cause the terminal device to perform operations comprising:
• receiving first configuration information, sent by a network device, wherein the first configuration information is configured to determine configuration information of pre-configured resource;
• in response to the pre-configured resource being activated, transmitting uplink data or receiving downlink data via the pre-configured resource;
• wherein in response to the pre-configured resource being uplink pre-configured resource, the processor is configured to call and run the computer program stored in the memory to cause the terminal device to perform operations comprising:
• in response to the terminal device determining that small data needs to be transmitted, selecting random access resource corresponding to the small data to initiate random access process, and sending an RRC resume request message, configured to apply for activating the pre-configured resource, to the network device;
• and
• receiving an RRC release message sent by the network device, and performing integrity protection verification for the RRC release message;
• wherein in response to the verification passing, the pre-configured resource is activated by the terminal device;
• and
• in response to the verification failing, the terminal device enters an idle state, and context of the terminal device is released by the terminal device.

• receiving a paging message sent by the network device, wherein the paging message carries fifth indication information, and the fifth indication information is configured to indicate the terminal device to activate the pre-configured resource and prepare to receive the small data through the pre-configured resource;
• in response to the terminal device determining that small data needs to be transmitted, selecting random access resource to initiate random access process, and sending an RRC resume request message, configured to apply for activating the pre-configured resource, to the network device;
