Abstract

A method for controlling signal transmission includes detecting whether there is a requesting terminal that requests to establish a wireless connection and turning off a sending function of sending beacon frames if there is no requesting terminal.

Claims

1. A method for controlling signal transmission, comprising:

detecting whether there is a requesting terminal that requests to establish a wireless connection;

turning off a sending function of sending beacon frames and continuing to receive probe request frames, if there is no requesting terminal;

receiving a probe request frame from a requesting terminal;

judging whether a wireless connection with the requesting terminal was previously established;

turning on the sending function if a wireless connection with the requesting terminal was previously established;

updating, if no wireless connection with the requesting terminal was previously established, an accumulated number that records a number of probe request frames from the requesting terminal; and

turning on the sending function when the accumulated number is greater than or equals to a preset number.

2. The method according to claim 1, wherein detecting whether there is a requesting terminal includes:

detecting whether there is a requesting terminal in a continuous time period of a preset time length.

3. The method according to claim 1, wherein judging whether a wireless connection with the requesting terminal was previously established includes:

acquiring identification information of the requesting terminal; and

searching a preset history database to determine whether the history database contains a historical connection device that matches the identification information of the requesting terminal.

4. The method according to claim 1, further comprising:

adding identification information of the requesting terminal into a preset blacklist if an operation of establishing a wireless connection with the requesting terminal fails.

5. An electronic device, comprising:

a processor; and

a memory storing instructions that, when executed by the processor, cause the processor to;

detect whether there is a requesting terminal that requests to establish a wireless connection;

turn off a sending function of sending beacon frames and continue to receive probe request frames, if there is no requesting terminal;

receive a probe request frame from a requesting terminal;

judge whether a wireless connection with the requesting terminal was previously established;

turn on the sending function if a wireless connection with the requesting terminal was previously established;

update, if no wireless connection with the requesting terminal was previously established, an accumulated number that records a number of probe request frames from the requesting terminal; and

turn on the sending function when the accumulated number is greater than or equals to a preset number.

6. The electronic device according to claim 5, wherein the instructions further cause the processor to:

detect whether there is a requesting terminal in a continuous time period of a preset time length.

7. The electronic device according to claim 6, wherein the instructions further cause the processor to:

acquire identification information of the requesting terminal; and

search a preset history database to determine whether the history database contains a historical connection device that matches the identification information of the requesting terminal.

8. The electronic device according to claim 6, wherein the instructions further cause the processor to:

add identification information of the requesting terminal into a preset blacklist if an operation of establishing a wireless connection with the requesting terminal fails.

9. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor of a terminal, cause the terminal to:

detect whether there is a requesting terminal that requests to establish a wireless connection;

turn off a sending function of sending beacon frames and continue to receive probe request frames, if there is no requesting terminal;

receive a probe request frame from a requesting terminal;

judge whether a wireless connection with the requesting terminal was previously established;

turn on the sending function if a wireless connection with the requesting terminal was previously established;

update, if no wireless connection with the requesting terminal was previously established, an accumulated number that records a number of probe request frames from the requesting terminal; and

turn on the sending function when the accumulated number is greater than or equals to a preset number.
