Abstract

Embodiments of the present disclosure disclose a terminal anti-lost method and a terminal, to resolve a problem that a lost terminal is difficult to find when a user discovers in a timely manner that the terminal is lost. The method in the embodiments of the present disclosure includes: first detecting, by the terminal when receiving a specific instruction, whether the terminal is currently in a lock screen state, where the specific instruction represents an instruction of controlling the terminal to decrease volume and/or an instruction of preventing the terminal from receiving a carrier signal; and skipping executing, by the terminal, the instruction when it is determined that the terminal is in the lock screen state, and controlling the terminal to increase the volume and/or play an alarm tone by using a loudspeaker.

Claims

1. A terminal anti-lost method comprising:

receiving, by a terminal, a specific instruction, wherein the specific instruction comprises at least one of an instruction for controlling the terminal to decrease its volume or an instruction for preventing the terminal from receiving a carrier signal;

in response to receiving the specific instruction, detecting, by the terminal, whether the terminal is currently in a lock screen state;

skipping, by the terminal, execution of the specific instruction when the terminal is in the lock screen state and controlling the terminal to increase a volume and/or play an alarm tone from a loudspeaker; and

executing, by the terminal, the specific instruction when the terminal is not in the lock screen state.

2. The method of claim 1, wherein the instruction for controlling the terminal to decrease its volume comprises one or more of a switch-off instruction, a mute instruction, or a volume decreasing instruction, and wherein the instruction for preventing the terminal from receiving a carrier signal comprises one or more of the switch-off instruction or a subscriber identity module-card (SIM-card) removing instruction.

3. The method of claim 1, further comprising:

detecting, by the terminal, headset insertion when a headset is inserted into the terminal; and

deactivating, by the terminal, the headset insertion when the terminal is in the lock screen state.

4. The method of claim 3, further comprising:

prompting, by the terminal, a user to cancel the lock screen state of the terminal prior to deactivating the headset insertion; and

deactivating the headset insertion when the lock screen state of the terminal is not canceled in a predetermined time.

5. The method of claim 1, further comprising:

prompting, by the terminal, a user to cancel the lock screen state of the terminal prior to skipping executing the specific instruction; and

skipping, by the terminal, the execution of the specific instruction when the lock screen state of the terminal is not canceled in a predetermined time.

6. The method of claim 1, further comprising:

obtaining, by the terminal, a biometric feature; and

uploading the biometric feature to a server.

7. The method of claim 1, further comprising:

obtaining, by the terminal, an environmental parameter of an environment in which the terminal is located; and

uploading the environmental parameter to a server.

8. The method of claim 1, further comprising stop playing, by the terminal, the alarm tone when the lock screen state of the terminal is canceled.

9. The method of claim 1, further comprising:

obtaining, by the terminal, a biometric feature; and

sending the biometric feature to another terminal.

10. The method of claim 1, further comprising:

obtaining, by the terminal, a biometric feature;

uploading the biometric feature to a server; and

sending the biometric feature to the other terminal.

11. The method of claim 1, further comprising:

obtaining, by the terminal, an environmental parameter of an environment in which the terminal is located; and

sending the environmental parameter to another terminal.

12. The method of claim 1, further comprising:

obtaining, by the terminal, an environmental parameter of an environment in which the terminal is located;

uploading the environmental parameter to a server; and

sending the environmental parameter to the other terminal.

13. A terminal, comprising:

a loudspeaker;

an input device;

a memory comprising operating instructions; and

a processor coupled to the loudspeaker, the input device, and the memory, wherein the operating instructions cause the processor to be configured to;

receive a specific instruction, wherein the specific instruction comprises at least one of an instruction for controlling the terminal to decrease its volume or an instruction for preventing the terminal from receiving a carrier signal;

in response to receiving the specific instruction, detect whether the terminal is currently in a lock screen state;

skip execution of the specific instruction when the terminal is in the lock screen state control the terminal to increase a volume and/or play an alarm tone from the loudspeaker; and

execute the specific instruction when the terminal is not in the lock screen state.

14. The terminal of claim 13, wherein controlling the terminal to decrease its volume comprises one or more of a switch-off instruction, a mute instruction, or a volume decreasing instruction, and wherein the instruction for preventing the terminal from receiving a carrier signal comprises one or more of the switch-off instruction or a subscriber identity module-card (SIM-card) removing instruction.

15. The terminal of claim 13, wherein the operating instructions further cause the processor to be configured to:

detect a headset insertion when a headset is inserted into the terminal; and

deactivate the headset insertion when the terminal is in the lock screen state.

16. The terminal of claim 15, wherein the operating instructions further cause the processor to be configured to:

prompt a user to cancel the lock screen state of the terminal before deactivating the headset insertion; and

deactivate the headset insertion when the lock screen state is not canceled in a predetermined time.

17. The terminal of claim 13, wherein the operating instructions further cause the processor to be configured to:

prompt a user to cancel the lock screen state of the terminal before skipping the specific instruction; and

skip execution of the specific instruction when the lock screen state is not canceled in a predetermined time.

18. The terminal of claim 13, further comprising a transmitter, wherein the operating instructions further cause the processor to be configured to:

obtain a biometric feature; and

either transmit the biometric feature to a server, transmit the biometric feature to another terminal, or transmit the biometric feature to each of the server and the other terminal.

19. The terminal of claim 13, wherein the terminal further comprises a transmitter;

and wherein the operating instructions further cause the processor to be configured to;

obtain an environmental parameter of an environment in which the terminal is located; and

either transmit the environmental parameter to a server, transmit the environmental parameter to another terminal, or transmit the environmental parameter to each of the server and to the other terminal.

20. The terminal of claim 13, wherein the operating instructions further cause the processor to be configured to stop playing the alarm tone when the lock screen state is canceled.
