Referring to FIG. 1 , a flow chart of the method includes the following steps:

Step S100, searching for a wireless network access point around the mobile phone. In this embodiment, after the mobile phone enters some occasions, when the mobile phone opens the wireless network interface, the wireless network access point around the mobile phone can be searched through the wireless network interface. It should be noted that, in this implementation, the term “around the mobile phone” refers to the range of the wireless network that can be obtained by the wireless network interface, and may specifically be determined according to the wireless signal strength of the actual wireless network interface, or may be preset to a certain range. . In a preferred embodiment, the wireless network access point is referred to as a WiFi hotspot.

Step S200: Obtain field information of the wireless network access point according to the wireless network access point. Generally, the wireless network sets corresponding field information to distinguish it from other wireless network access points. Therefore, after searching for the wireless network access point, the field information of the wireless network can be obtained. In a specific embodiment, the field information of the wireless network access point can represent the location of the access point, such as a school, a ward, a movie theater, and the like. As an example, the keyword information of the wireless network may be extracted according to field information of the wireless network access point, such as a "cinema" in a certain movie theater, a "school" in a certain school, a "ward" in a certain ward, and the like. The current location is determined based on the keyword information of the wireless network, that is, in a movie theater, a school, a ward, and the like.

In step S700, the field information is compared with the preset field database.

In step S300, it is determined whether the field information is in the field list of the preset field database. In a specific embodiment, the related preset occasion and its corresponding field information may be stored in the system. When it is determined that the field information used to represent the current location meets the preset field information in the database, the mobile phone is currently in the preset state. occasion. In a preferred embodiment, the field column of the preset field database The table includes places where a quiet environment is required, such as a movie theater, school, and/or intensive care unit. If the current location is in a preset occasion, step S400 is performed. In a preferred embodiment, when extracting keyword information in the field information, it can be determined whether the keyword information is in a field list of the field database, such as "cinema" in the keyword xx movie theater, "school" in xx school , "the ward" in the xx intensive care unit. When the extracted keywords are in the field list of the preset field database, step S400 is performed.

In step S400, the mobile phone is switched to a preset profile. In this embodiment, the preset preset mode is a mode in which the mobile phone is muted, such as a silent mode or a vibration mode. It should be noted that, in other embodiments, if the mobile phone is turned off or the flight mode, etc., the mode of cutting off the communication signal mode, the equivalent replacement of this embodiment should be considered.

In a preferred embodiment, if the field information is in the field list of the field database, before the step S400 is performed to switch the mobile phone to the preset scene mode, the method may further include:

Step S500, timing the reachable state of the signal of the mobile phone and the wireless network access point. In this embodiment, the so-called signal reachable means that the mobile phone can search for the wireless network access point. Specifically, when it is determined in step S400 that the field information is in the field list of the field database, the timer may be triggered to perform timing.

In step S600, it is determined whether the duration of the recording exceeds a preset duration. In a specific embodiment, the preset duration may be determined according to experience, or may be preset directly in the system. If it is determined in step S600 that the duration of the recording exceeds the preset duration, step S400 is executed to switch the mobile phone to the preset scene mode. Of course, if step S600 determines that the recorded duration does not exceed the preset duration, the timing may be continued.
