Half-duplex periodic message transmission method, terminal and storage medium

A first terminal, comprising:

• at least one processor;
• and
• a memory in communication connection with the at least one processor;
• wherein the memory stores instructions executable by the at least one processor, and the instructions, when being executed by the at least one processor, cause the at least one processor to:
• acquire a message type of a message to be transmitted, wherein the message type comprises:
• a timely type and a temporary type;
• in response to determining that the message to be transmitted is a message of the timely type, allocate a corresponding transmission protect period for the message of the timely type, and preferentially transmit the message of the timely type to a second terminal within the transmission protect period, so that the second terminal executes an operation corresponding to the message of the timely type, wherein the transmission protect period is used for transmitting the message of the timely type, wherein a half-duplex communication mode is used between the first terminal and the second terminal;
• and
• in response to determining that the message to be transmitted is a message of the temporary type, acquire a sending moment of the message of the temporary type, wherein the sending moment is within a period between a current transmission protect period and a next transmission protect period;
• acquire a threshold moment which is a first preset duration before a start moment of the next transmission protect period;
• and determine whether the sending moment is before the threshold moment, in response to determining that the sending moment is before the threshold moment, transmit the message of the temporary type at the sending moment, otherwise, adjust the sending moment to be after the next transmission protect period.
