receive other data in a data packet which carries the preamble, and activate the processor in the sleep state; and based on a total quantity of bytes of data in the data packet received being equal to a reference quantity threshold, determine that a destination address is received, and output a trigger signal, wherein the reference quantity threshold is equal to a length of the destination address in the data packet, and the trigger signal is configured to instruct the processor to perform determination based on the destination address; and
the processor is configured to, based on detecting the trigger signal, control the receiver to stop receiving the data packet and control the terminal to enter the sleep state, based on determining that the destination address is not an address of the terminal;
wherein the receiver is further configured to continue the sleep state in response to not detecting the preamble.
2. The terminal according to claim 1 , wherein the processor is configured to control the terminal to enter a sleep state, based on determining that the destination address is not the address of the terminal.
3. The terminal according to claim 1 , wherein the processor is further configured to control the receiver to continue receiving the data packet, based on determining that the destination address is the address of the terminal.
4. The terminal according to claim 3 , wherein the receiver is further configured to enter a sleep state in response to completion of receiving the data packet.
5. The terminal according to claim 1 , wherein the receiver is configured to store the destination address in a first-in first-out fashion, and
the processor is configured to read the destination address from the receiver in the first-in first-out fashion.
6. The terminal according to claim 1 , wherein the data packet comprises a preamble, the destination address, and data content, wherein the preamble, the destination address, and the data content are sequentially defined.
7. A communication system, comprising a server, a gateway and at least one terminal as defined in claim 1 , wherein the server is configured to transmit a data packet to the terminal via the gateway.
8. A communication method, applicable to a terminal operating in a periodically sleep state, the sleep state meaning that an overall of the terminal is in the sleep state, and the terminal comprising a receiver and a processor;
wherein the method comprises:
performing channel activity detection by the receiver based on determining that the sleep state lasts for a reference duration;
to based on detecting a preamble by the channel activity detection, receiving, by the receiver, other data in a data packet which carries the preamble, and activating, by the receiver, the processor in the sleep state;
determining that a destination address is received and outputting a trigger signal by the receiver of the terminal to based on a total quantity of bytes of data in the data packet received being equal to a reference quantity threshold, wherein the reference quantity threshold is equal to a length of the destination address in the data packet, and the trigger signal is configured to instruct the processor to perform determination based on the destination address;
to based on detecting the trigger signal by the processor of the terminal, controlling the receiver to stop receiving the data packet and controlling the terminal to enter the sleep state, based on determining that the destination address is not an address of the terminal; and
to based on not detecting the preamble, continuing entering the sleep state by the receiver.
9. The communication method according to claim 8 , wherein controlling the receiver to stop receiving the data packet, based on determining that the destination address is not the address of the terminal comprises:
controlling the terminal to enter a sleep state, based on determining that the destination address is not the address of the terminal.
10. The communication method according to claim 8 , further comprising:
controlling the receiver by the processor to continue receiving the data packet, based on determining that the destination address is the address of the terminal.
11. The communication method according to claim 10 , further comprising:
based on completion of receiving the data packet by the receiver, entering a sleep state by the receiver.
12. The communication method according to claim 8 , further comprising:
storing data received in a first-in first-out fashion by the receiver, and
reading the destination address by the processor from the receiver in the first-in first-out fashion.
13. The communication method according to claim 8 , wherein the data packet comprises a preamble, the destination address, and data content, wherein the preamble, the destination address, and the data content are sequentially defined.
14. A non-transitory computer-readable storage medium storing at least one computer program thereon, wherein the at least one computer program, when run by a terminal, causes the terminal to perform:
performing channel activity detection by a receiver of the terminal based on determining that a sleep state lasts for a reference duration, wherein the terminal operates in a periodically sleep state, the sleep state meaning that an overall of the terminal is in the sleep state, and the terminal comprises the receiver and a processor;
based on detecting a preamble by the channel activity detection, receiving, by the receiver, other data in a data packet which carries the preamble, and activating, by the receiver, the processor in the sleep state;
determining that a destination address is received and outputting a trigger signal by the receiver of the terminal to based on a total quantity of bytes of data in the data packet received being equal to a reference quantity threshold, wherein the reference quantity threshold is equal to a length of the destination address in the data packet, and the trigger signal is configured to instruct the processor to perform determination based on the destination address;
based on detecting the trigger signal by a processor of the terminal, controlling the receiver to stop receiving the data packet and controlling the terminal to enter the sleep state, that based on determining that the destination address is not an address of the terminal; and
based on not detecting the preamble, continuing entering the sleep state by the receiver.
