The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, an application layer, an application framework layer, an Android runtime (Android runtime) and system library, and a kernel layer from top to bottom.

The application layer may include a series of application packages.

As shown in fig. 2, the application package may include applications such as camera, gallery, calendar, phone call, map, navigation, WLAN, bluetooth, music, video, short message, etc.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 2, the application framework layers may include a window manager, content provider, view system, phone manager, resource manager, notification manager, and the like.

The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

The view system includes visual controls such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The phone manager is used to provide a communication function of the terminal 100. Such as management of call status (including on, off, etc.).

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and the like.

The notification manager enables the application to display notification information in the status bar, can be used to convey notification-type messages, can disappear automatically after a short dwell, and does not require user interaction. Such as a notification manager used to inform download completion, message alerts, etc. The notification manager may also be a notification that appears in the form of a chart or scroll bar text at the top status bar of the system, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, text information is prompted in the status bar, a prompt tone is given, the terminal vibrates, an indicator light flashes, and the like.

The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system.

The core library comprises two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. And executing java files of the application program layer and the application program framework layer into a binary file by the virtual machine. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.

The following describes exemplary workflow of the terminal 100 software and hardware in connection with capturing a photo scene.

When the touch screen 131 receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and taking a control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera drive by calling a kernel layer, and captures a still image or a video through the camera 140.

The terminal 100 in the embodiment of the present application may be a mobile phone, a tablet computer, a wearable device, a notebook computer, a television, and the like.

Fig. 3 is a schematic diagram for illustrating a user interface on a terminal (e.g., terminal 100 of fig. 1). In some implementations, a user can open a corresponding application by touching an application icon on the user interface, or can open a corresponding folder by touching a folder icon on the user interface.

Currently, most terminals have WLAN functionality. The terminal can discover nearby WLAN hotspots through WLAN scanning, and can realize the function of surfing the internet by establishing connection with the scanned available WLAN hotspots.

After the terminal starts the WLAN function, before the terminal is not accessed to the WLAN network, the terminal always executes WLAN scanning according to a fixed scanning interval, and the terminal can be automatically accessed to the WLAN network only in the coverage range of the WLAN hotspot storing access information; however, the terminal scans at a fixed scanning interval in an area not covering the WLAN hotspot and in a coverage area of the WLAN hotspot where access information is not stored, thereby increasing power consumption of the terminal.

In view of this, in the embodiment of the present invention, when the terminal is in the WLAN on state, the current location information of the terminal is determined, and whether the terminal is in the target area is determined according to the current location information of the terminal, where the target area is located when the terminal has historically and successfully accessed the WLAN network; when the terminal is in the target area, the terminal indicates that the WLAN network which is successfully accessed by the terminal history exists in the current area, and the terminal indicates that the WLAN hot spot which is stored by the terminal exists in the area, and the terminal performs WLAN scanning by using a shorter scanning interval, so that the stored WLAN hot spot can be quickly scanned; when the terminal is not in the target area, it indicates that there is no stored WLAN hotspot in the area where the terminal is currently located, and the terminal may use a longer scanning interval to perform WLAN scanning, or the terminal may not perform WLAN scanning when it is determined that the terminal is not in the target area, so that power consumption of the terminal in performing WLAN scanning can be effectively reduced.

Furthermore, after the terminal is determined to be in the target area according to the current position information of the terminal, the motion state of the current terminal can be determined, and the moving speeds of the terminal are different in different motion states; in the target area, the faster the terminal moves, the faster the terminal can enter the coverage of the stored WLAN hotspot, and at this time, the terminal needs to use a smaller scanning interval to scan the stored WLAN hotspot as soon as possible, so as to quickly establish connection with the scanned stored WLAN hotspot; when the terminal moving speed is low, the time for the terminal to enter the coverage range of the stored WLAN hot spot is long, and at the moment, the terminal can use a large scanning interval to reduce the power consumption of the terminal.

As shown in fig. 4, a method for determining a scan interval of a WLAN network according to an embodiment of the present invention includes:

step S401, when the terminal is in a WLAN starting state, determining the current position information of the terminal;

step S402, if the terminal is determined to be in the target area according to the current position information of the terminal, the terminal determines the current motion state; the target area is an area where the terminal is located when the terminal is successfully accessed to the WLAN network historically;

step S403, the terminal determines a scanning interval used for WLAN scanning according to the current motion state; wherein the scanning interval is inversely related to the moving speed of the terminal under different motion states.

Several scenarios in which the embodiment of the present invention needs to determine the scan interval of the WLAN network are described below:

scene 1: and the terminal screen is lightened.

Responding to the operation of starting the terminal triggered by a user, and lightening a terminal screen; when the terminal is determined to be in a WLAN starting state, the terminal acquires identification information of a base station currently accessed by the terminal, such as Lac and CellId, by calling a getCellLocation () interface in a TelephonManager class; and judging whether the current access base station is in a target area or not according to the identification information of the current access base station, if so, further judging the current motion state of the terminal, and determining the scanning interval for WLAN scanning according to the motion state of the terminal.

Scene 2: the terminal turns on the WLAN function.

For example, as shown in fig. 5, a user may turn on a WLAN function of the terminal through a WLAN network switch in a shortcut touch area in a terminal display interface; alternatively, as shown in fig. 6, the user may turn on the WLAN function of the terminal by setting a WLAN network control option in the page.

Responding to the operation of starting a WLAN function triggered by a user, determining that the terminal enters a WLAN starting state, and acquiring identification information, such as Lac and CellId, of a base station currently accessed by the terminal by calling a getCellLocation () interface in a TelephonManager class by the terminal; and judging whether the current access base station is in a target area or not according to the identification information of the current access base station, if so, further judging the current motion state of the terminal, and determining the scanning interval for WLAN scanning according to the motion state of the terminal.

Scene 3: the base station to which the terminal is accessed changes.

When the terminal is in a WLAN starting state, the terminal acquires identification information of a base station currently accessed by the terminal, such as Lac and CellId, by calling a getCellLocation () interface in a TelephonManager class; and the terminal judges whether the current terminal is in a target area according to the identification information of the current accessed base station, if so, further judges the current motion state of the terminal, and determines the scanning interval for carrying out WLAN scanning according to the motion state of the terminal.

Scene 4: the motion state reported by the terminal changes.

When the terminal is in a WLAN starting state, a motion detector of the terminal reports a new motion state, whether the current scanning interval is a longer scanning interval is judged, if so, the WiFi hotspot information currently connected to the terminal is not in a target area, and even if the motion state changes, the WLAN scanning interval does not need to be adjusted; if not, the WLAN hotspot information currently connected to the terminal is in the target area, and the terminal needs to adjust to a corresponding scanning interval according to the motion state.

In step S402, after determining the current location information, the terminal may determine whether the terminal is in the target area according to the following manner:

the terminal judges whether the stored information of the target area contains the identification information of the currently accessed base station; if so, determining that the terminal is in the target area, otherwise, determining that the terminal is not in the target area;

the information of the target area includes identification information of a base station accessed when the terminal is in a WLAN connection state.

It should be noted that, in the embodiment of the present invention, a database of a correspondence relationship between a target area and a WLAN hotspot is pre-constructed; in the database, the corresponding relation between the WLAN hotspot accessed by the terminal history and the base station accessed when the WLAN hotspot is accessed is stored;

an optional implementation manner is that, a database table structure is used in the database to store the corresponding relationship between the identification information of the WLAN hotspot and the identification information of the access base station;

wherein, the identification information of the base station comprises Lac (area code) and CellId (cell identification);

the identification information of the WLAN hotspot includes SSID (hotspot name) and Security, where the Security value is an integer and is defined as: security is 0, indicating an unencrypted hotspot; security is 1, indicating WEP encryption hotspot; the Security is 2, which represents a PSK encryption hotspot; security is 3, which represents EAP encryption hot spot; the Security is 4, which represents a WAPI _ PSK encryption hotspot; security is 5, indicating a WAPI _ CERT encryption hotspot.

For example, the database table structure in the database of the embodiment of the present invention may be as shown in table 1:

Lac	CellId	SSID	Security
				21507	56667915	X_2019	2

TABLE 1

And obtaining the Lac and the CellId of the base station accessed currently at the terminal, searching from the database, determining whether the database contains the Lac and the CellId of the base station accessed currently at the terminal, and if so, determining that the terminal is in the target area.

It should be noted that the database stored in advance in the embodiment of the present invention is generated according to the identification information of the base station accessed while accessing the WLAN network when the terminal accesses the WLAN network historically.

In practice, embodiments of the present invention may construct the database according to the following ways:

when a terminal establishes connection with a certain WLAN hotspot for the first time, the identification information of the WLAN hotspot connected at that time and the identification information of a currently accessed base station are acquired, and the acquired identification information of the WLAN hotspot and the identification information of the base station are bound and stored in a database.

It should be noted that, in the database according to the embodiment of the present invention, the identification information of the same WLAN hotspot may correspond to the identification information of one or more base stations, and the identification information of the same base station may also correspond to the identification information of one or more WLAN hotspots.

The embodiment of the present invention further needs to update the correspondence between the identification information of the WLAN hotspot stored in the database and the identification information of the access base station in real time, including but not limited to adding the correspondence between the identification information of the WLAN hotspot and the identification information of the access base station, and deleting the correspondence between the identification information of the WLAN hotspot and the identification information of the access base station.

Aiming at the situation of the corresponding relation between the identification information of the newly added WLAN hotspot and the identification information of the access base station:

case 1: the terminal is connected to the WLAN hotspot.

As shown in fig. 7, a schematic flow chart of a complete method for updating a database for a terminal under the circumstance mainly includes the following steps:

step S701, a hotspot position management module of the terminal receives a WLAN connection state change broadcast sent by a WLAN network connection module; for example, the network connection status CHANGE is broadcast as CONNECTIVITY _ CHANGE;

it should be noted that the WLAN connection state change broadcast includes a transition from the WLAN connected state to the WLAN disconnected state, or a transition from the WLAN disconnected state to the WLAN connected state.

Step S702, the hotspot position management module of the terminal judges whether the current WLAN connection state is a WLAN connected state according to the received WLAN connection state change broadcast, if so, step S704 is executed; otherwise, executing step S703;

step S703, the terminal scans the WLAN according to the current WLAN scanning interval;

step S704, the hotspot position management module of the terminal acquires Lac and CellId of a base station accessed by the current equipment by calling a getCellLocation () interface in a TelephonManager class, and simultaneously acquires SSID and Security of the current equipment connecting hotspot by using a getWifiInfo () interface in a WifiManager class;

the identification information of the WLAN hotspot currently connected to the terminal and the identification information of the base station currently connected to the terminal may be { Lac _ B, CellId _ B, SSID _1, Security _2 }.

Step S705, the terminal determines that the identification information of the WLAN hotspot and the identification information of the base station which are just acquired are not inquired through inquiring the database;

step S706, the terminal adds the acquired WLAN hotspot information and the identification information of the base station to a WiFi hotspot position database according to the { Lac _ B, CellId _ B, SSID _1 and Security _2} formats.

Wherein, let Lac _ B be 21075; CellId _ B is 59791836; SSID _1 is Android (Android); security _1 is 3. Table 2 below is the database after addition.

Lac	CellId	SSID	Security
				21507	56667915	X_2019	2
21075	59791836	Android	3

TABLE 2

Case 2: when the terminal is in the WLAN connection state, the base station to which the terminal accesses changes.

As shown in fig. 8, a schematic flow chart of a complete method for updating a database for another terminal under the above situation mainly includes the following steps:

step S801, a hotspot position management module of a terminal receives callback of base station change; for example, the callback of the CHANGE of the base station is CELL _ LOCATION _ CHANGE;

step S802, the hotspot position management module of the terminal acquires Lac and CellId of a base station accessed by the current equipment by calling a getCellLocation () interface in a TelephonManager class, and updates the identification information of the current base station;

step S803, the hotspot location management module of the terminal determines whether the current WLAN connection state is a WLAN connected state, and if so, executes step S805; otherwise, go to step S804;

step S804, the terminal scans the WLAN according to the current WLAN scanning interval;

step S805, the hotspot position management module of the terminal acquires the SSID and the Security of the current equipment connecting hotspot through a getWifiInfo () interface in a WifiManager class;

the identification information of the WLAN hotspot currently connected to the terminal and the identification information of the base station currently connected to the terminal may be { Lac _ C, CellId _ C, SSID _2, Security _2 }.

Step S806, the terminal queries a database through { Lac _ C, CellId _ C, SSID _2 and Security _2 to determine that the information of the WLAN hotspot just acquired and the identification information of the base station are not queried;

step S807, the terminal updates the acquired identification information of the WLAN hotspot and the identification information of the base station into the database according to the { Lac _ C, CellId _ C, SSID _2, Security _2} format.

Wherein, let Lac _ C be 21556; CellId _ C is 56697852; SSID _1 is Android (Android); security _1 is 3. The updated database is shown in table 3 below.

Lac	CellId	SSID	Security
				21507	56667915	X_2019	2
21075	59791836	Android	3
				21556	56697852	Android	3

TABLE 3

Aiming at the situation of deleting the corresponding relation between the identification information of the WLAN hotspot and the identification information of the access base station:

When the stored WLAN hotspot is deleted according to the user operation, the terminal needs to delete the corresponding relationship related to the WLAN hotspot in all the corresponding relationships of the database.

After receiving the saved hotspot state CHANGE broadcast, the hotspot location management module of the terminal, for example, the saved hotspot state CHANGE broadcast is CONFIGURED _ network _ CHANGE; the terminal determines that the cause of the change is REMOVE, acquires the SSID and the Security of the removed hotspot, and deletes all the records corresponding to the SSID and the Security from the database. For example, if the hot spot name is X _2019 and the WiFi hot spot with the security parameter of 2 is removed, the updated state of the corresponding database is as shown in table 4 below:

Lac	CellId	SSID	Security
				21075	59791836	Android	3
21556	56697852	Android	3

TABLE 4

After the terminal is determined to be in the target area, determining a WLAN scanning interval according to the motion state;

in implementation, the terminal collects sensor data through the motion detection sensor, and determines the current motion state according to the collected sensor data.

Specifically, the Motion detection module of the terminal opens a Motion Detector Sensor through an interface in the SensorManager, and when the Sensor detects that the Motion state changes, the onsensor () method is called back to report the current Motion state to the Motion state detection module for recording.

The embodiment of the invention predefines the scanning intervals corresponding to different motion states;

after the current motion state of the terminal is determined, the scanning interval used for scanning the WLAN network corresponding to the current motion state is determined according to the corresponding relation between the current motion state and the scanning interval.

The motion state of the terminal includes but is not limited to:

a static state, a low-speed motion state and a high-speed motion state.

It should be noted that the moving speed ranges corresponding to the low-speed moving state and the high-speed moving state may be predefined, and after the terminal determines the moving speed of the terminal according to the collected sensor data, the moving state of the terminal is determined according to the current moving speed of the terminal.

For example, when the user walks, the terminal determines that the terminal is in a low-speed motion state when the terminal determines that the moving speed of the terminal is low according to the collected sensor data; when the user runs, the terminal determines that the moving speed of the terminal is high according to the collected sensor data, and determines that the terminal is in a high-speed motion state.

For example, the predefined correspondence between the terminal motion state and the scanning interval according to the embodiment of the present invention may be as shown in table 5 below:

state of motion of terminal	Scanning interval
		At rest state	Interval WhenStill (600 seconds)
Low speed motion state	Interval WhenWalk (60 seconds)
		State of high speed motion	Interval WhenRun (30 seconds)

TABLE 5

In addition, in the embodiment of the present invention, a scanning interval when the terminal is not in the target area may be preset, for example, when the terminal is not in the target area, a value of the corresponding scanning interval intervalOutRange may be 600 seconds.

It should be noted that, when the terminal is not in the target area, the corresponding scanning interval is greater than the scanning interval when the terminal is in the target area; and when the terminal is in the target area, different scanning intervals are corresponding to different motion states of the terminal, and the scanning intervals are shorter as the moving speed corresponding to the motion states is higher.

For example, when the terminal is not in the target area, a longer scanning interval is used, and the longer scanning interval may be set to intervalOutRange: {10 seconds, 30 seconds, 60 seconds, 180 seconds, 300 seconds, 600 seconds }, and finally keeping scanning once every 600 seconds;

it should be noted that the previous three scanning intervals are short, and it is considered that the current WLAN hotspot may correspond to identification information of many base stations, and the recorded identification information of the base stations is only a part, and at this time, the terminal may be connected to an unrecorded base station, but the actual position is still in the target area, so that the scanning is performed three times quickly.

When the terminal is in a target area, a shorter scanning interval is used, the shorter scanning interval is set according to the motion state of the terminal, when the motion state of the terminal is in a static state, the intervalWhenStill {30 seconds, 60 seconds, 120 seconds } is set, and the longest 120-second interval is kept for scanning in the static state; when the motion state of the terminal is a low-speed state, setting intervalWhenWalk {10 seconds, 20 seconds, 30 seconds, 60 seconds }, setting a maximum scanning interval of 60 seconds, and setting the scanning interval for the user terminal to walk, wherein generally, the possibility of walking into a WiFi hot spot coverage area is the highest, the walking speed is relatively not fast, and therefore the scanning interval is not suitable to be too short; when the motion state of the terminal is a high-speed state, intervalWhenRun {10 seconds, 20 seconds, 30 seconds } is set, and the maximum interval is 30 seconds, which is a scanning interval set when the user runs, and the motion speed is fast during running, and the time required for approaching the coverage area of the WiFi hotspot is short, so the scanning interval is set to be short.
