Detailed Description

The invention provides electronic equipment and a WIFI intelligent switching method thereof, which can intelligently switch a WIFI network according to the strength and the speed of a WIFI signal. In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and fig. 2, the method for WIFI intelligent switching of an electronic device provided by the present invention includes:

s100, when a WIFI intelligent switching mode is started, monitoring the current WIFI state and judging whether a triggering condition of intelligent switching is reached;

s200, when the strong and weak trigger conditions are reached, searching for WIFI with optimal signals to switch;

s300, when the download triggering condition is met, searching for WIFI with the optimal signal, prompting the download rate, and selecting switching according to user operation.

The embodiment can intelligently search and monitor the signal intensity and the downloading rate of the WIFI network, intelligently switch WIFI or inform a user, and the user can decide whether to switch WIFI or not. Before the WIFI smart switching mode is started, the WIFI needs to be started first and a last WIFI is successfully connected (as in step S10 in fig. 2). The method for judging whether the WIFI is started comprises the following steps:

public boolean isWIFIEnabled() {

return getWIFIState() == WIFI_STATE_ENABLED;

}

returning true indicates that WIFI is turned on, and returning false indicates that WIFI is not turned on.

After the user starts WIFI, all surrounding WIFI signals can be automatically displayed, if the saved WIFI information is to be acquired, the acquisition method can be achieved through a WIFI management class, such as WIFIManager, as follows:

WIFIManager WIFIManager =（WIFIManager）this.getSystemService（Context.WIFI_SERVICE）。

the method for judging whether the WIFI is connected comprises the following steps:

obtaining connection management classes

ConnectivityManager connectivityManager =

(ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

Obtaining network information through connection management classes

NetworkInfo WIFINetworkInfo = connectivityManager.getNetworkInfo（ConnectivityManager.TYPE_WIFI）；

WIFINetworkInfo.isConnected()

Returning true indicates a connection is made and false indicates no connection.

And then a dialog box can be popped up to prompt the user whether to start the WIFI intelligent switching mode. If the user starts the WIFI intelligent switching mode, the method goes to steps S100-S300; otherwise, the current WIFI connection is defaulted. WIFI is switched intelligently (such as a plurality of previously connected WIFI or free WIFI) sometimes based on the fact that a user does not need to switch WIFI frequently (such as WIFI signal fixation in an office or a home). And adding an opening and closing selection item of the WIFI intelligent switching mode in the WIFI connection option. And when a follow-up user needs, whether the WIFI intelligent switching mode is started or not can be selected autonomously. Therefore, the WIFI can be switched and used more flexibly according to the use environment of the user.

In step S100, when the WIFI intelligent switching mode is started, the current WIFI state needs to be monitored in real time and it is determined whether a triggering condition for intelligent switching is met (as shown in steps S110 to S130 in fig. 2). The WIFI state comprises the intensity and the downloading rate of a WIFI signal. The trigger conditions include strong and weak trigger conditions and download trigger conditions.

The method for acquiring the currently connected WIFI information comprises the following steps:

public WIFIInfo getConnectionInfo(){

}

the method returns a WIFIInfo object which contains the information of the currently connected WIFI.

Getmacaddress () = = null, this means that there is no WIFI connection.

Other methods for acquiring WIFI information:

WIFIinfo.getBSSID()；

WIFIinfo.getSSID()；

getipaddress (); obtaining an IP address

Getmacaddress (); obtaining MAC addresses

Getnetworkid (); obtaining a network ID

Wifininfo. getlinkseed (); obtaining the connection speed can let the user know the information

WIFIinfo, getRSI (), and signal strength for obtaining RSSI measurement

The method of obtaining information (including rate) of the current data transmission is as follows:

the methods getTotalRxBytes and getTotalTxBytes provided by the data management methods, such as TrafficStats, can be used.

public static long getTotalRxBytes() //Return number of bytesreceived since device boot

public static long getTotalTxBytes() //Return number of bytestransmitted since device boot

getTotalRxBytes is used for acquiring received data, and getTotalTxBytes is used for acquiring sent data.

For example, for the sending rate, a value is obtained by getTotalTxBytes first, a value is obtained by getTotalTxBytes after 500ms, and the current sending rate of the electronic device can be known by subtracting the absolute value of the two values and dividing the absolute value by 0.5, wherein the unit is byte/second.

In this embodiment, the strength triggering condition is that the strength of the current WIFI signal is lower than the first expected value a, or the download rate of the WIFI signal is lower than the second expected value B but no download is performed (for example, in the case of web browsing). When the strong and weak trigger conditions are reached, searching for WIFI with optimal signals for switching; the step S200 specifically includes:

step S210, judging whether a WIFI signal meeting intelligent switching is acquired, if so, executing step S220; otherwise, the process is not processed, and the process is ended. Thereafter, the process returns to step S100.

In this step, the method for judging a WIFI signal satisfying the intelligent switching specifically includes:

1. and judging whether the WIFI is connected or not and storing. If the WIFI signal is not connected (private WIFI) and a password needs to be entered, the system may try to connect strong but unusable WIFI. Only those that have been previously maintained can be directly connected. The saved WIFI List < WIFI configuration > may be obtained by obtaining WIFI information that the electronic device has saved, which may be obtained through wifimanager. The WIFIConfiguration object includes various attributes of WIFI, such as Network Id, ssid (service setidentifier), Status, and the like.

2. Judging whether the intensity of the new WIFI signal is compared with that of the currently connected WIFI signal and is equal to or greater than an intensity set value strength or not; or the new WIFI signal is stronger than the currently connected WIFI signal by an intensity threshold value. Only if the intensity of the new WIFI signal reaches or exceeds the intensity set value strength, the signal is strong and can be switched. Or the new WIFI signal is stronger than the previously connected WIFI signal, so that the switching significance is achieved.

And acquiring the scanned WIFI signal source, acquiring the WIF scanned by the electronic equipment through WIFIManagergetScanResults, and returning List < ScanResult >. The ScanResult includes information related to the WIF, such as ssid (service Set identifier), Level (signal strength), and the like.

3. On the basis of item 2, judging whether the download rate of the new WIFI signal is compared with the download rate of the currently connected WIFI signal and is equal to or greater than a rate set value speed or not; or the download rate of the new WIFI signal is greater than the rate threshold value than the currently connected WIFI signal. Meeting this condition has a switch significance.

The above 3 new WIFI signals meeting all the requirements belong to WIFI signals capable of being intelligently switched, and if the new WIFI exists, the WIFI signals meeting the requirements of intelligent switching can be obtained, and subsequent steps can be executed for switching. If the condition is not met, it is indicated that the currently connected WIFI signal is optimal, switching is not needed, the process may be ended, and the process returns to step S100 to continue monitoring.

And S220, comparing the WIFI signals meeting the intelligent switching, and finding out the optimal WIFI.

There may be more than one new WIFI signal that satisfies the above 3 conditions, and this step is performed to find the optimal WIFI signal. If there is only one, no comparison is necessary. When the comparison is carried out in the step, the WIFI signal with the highest downloading rate is found out, and if a plurality of WIFI signals are still available, whether the intensity of the WIFI signal reaches the stable value S or not can be continuously detected. And the optimal WIFI is satisfied by both.

Through the steps, the strength information of the WIFI signals can be acquired, but when the two WIFI signals are compared, some data processing is firstly carried out, the level is converted into the numerical value of RSSI measurement through a specific formula, and then the comparison is carried out.

WIFIManager defined the method of comparison as follows:

public static int compareSignalLevel(int rssiA, int rssiB) {

return rssiA - rssiB;

}

the type of parameters introduced and the method of comparison can be seen from the above method.

And step 230, switching the current WIFI to the optimal WIFI, and prompting after switching is completed. And then, the process is ended, and the process returns to the step S100 to continue monitoring.

And switching to the optimal WIFI, namely connecting the optimal WIFI. In the method for connecting the WIFI, the WIFIManager provides a connect method, which comprises the following steps:

public void connect(WIFIConfiguration config, ActionListenerlistener)

when the method is called, a snoop is transmitted, by means of which the upper layer is informed when a connection is made or when there are other connection events.

If the electronic equipment is not in the condition of large flow, the step is automatically switched in the background, and Toast (prompt information similar to a prompt box) is popped up to inform the user after the switching is finished. If the electronic equipment is in a large flow condition, data transmission is large, such as watching a video, downloading a file or a video and the like. In the step, the user can be prompted by popping the frame first, so that the user can decide whether to switch the WIFI network, the switching is automatically switched to the optimal WIFI in the background, and then the user is not prompted any more.

In this embodiment, the download trigger condition is that the download rate of the current WIFI signal is continuously lower than the third expected value C, the rate fluctuation range is smaller than the fourth expected value D, and the duration time exceeds the time threshold T. In this embodiment, the download trigger condition may be three cases, that is, any one of the duration that the download rate is lower than the third expected value C or the duration that the rate fluctuation range is smaller than the fourth expected value D exceeds the time threshold T, or both of the durations exceed the time threshold T. The download trigger condition corresponds to a situation when the electronic device is in continuous file download and the rate does not reach the desired download rate. In one embodiment, the third expected value C is 50 kb/s, the fourth expected value D is 10 kb/s, and the time threshold T is 15 seconds. If the downloading speed is stabilized at 35-40 kb/s and lasts for 15 seconds, the downloading triggering condition of WIFI intelligent switching is achieved. If each download is expected, the background service can search for the fastest WIFI at present, and the third expected value C can be set higher.

The step S300 specifically includes:

step S310, judging whether a WIFI signal meeting intelligent switching is acquired, if so, executing step S320; otherwise, the process is not executed, the process is ended, and the process returns to the step S100. The details of this step are the same as those of step S210, and are not described herein.

And S320, comparing the WIFI signals meeting the intelligent switching, and finding out the optimal WIFI. The details of this step are the same as those of step S320, and are not described herein.

Step S330, judging whether the optimal WIFI is the WIFI cancelled by the user: if yes, processing is not carried out, the process is ended, and the step S100 is returned; otherwise, step S340 is performed.

If the optimal WIFI is the WIFI which has been cancelled by the user before, it is indicated that the user does not want to connect the WIFI (some WIFI has potential safety hazards or other problems are cancelled by the user), and the current WIFI is not switched. If not, step S340 may be performed.

Step S340, prompting switchable WIFI and intensity and rate information thereof, and detecting whether a user selects switching: if so, step 230 is executed, otherwise, step S350 is executed.

This step is the case of downloading, and the user may desire to switch or may be bothersome to not switch. Therefore, a prompt box can be popped out to inform a user of finding out more optimal WIFI, and the name, signal strength, speed and other information of the WIFI are attached, so that the user can select whether to switch. Here, the handover may be performed according to step 230.

And S350, recording the MAC address of the currently connected WIFI and the MAC address of the optimal WIFI. And then, the process is not processed, and the process is ended.

And recording MAC addresses of the WIFI network and the WIFI network so as to be convenient for use when the follow-up WIFI signal meeting intelligent switching is compared. Duplicate acquisitions of MAC addresses may be reduced.

It should be understood that once the connection of the WIFI is started and the WIFI intelligent switching mode is started, the background system can always run, monitor the current WIFI state and judge whether the triggering condition of the intelligent switching is achieved. After the process is finished each time, the process returns to step S100 to continue monitoring and determining. And only when the WIFI is turned off, or the WIFI is not connected, or the WIFI intelligent switching mode is exited, the monitoring and judging states are completely turned off, and the corresponding background service is turned off. The expected value (A, B, C, D), the intensity set value strength, the intensity threshold, the rate set value speed, the rate threshold and the like mentioned in the above embodiment can be default values before the electronic device leaves a factory, and a setting interface can also be provided for a user to set and store, so that the WIFI intelligent switching can better meet the personalized requirements of the user. The background service determines thresholds and desired values for each situation based on these values.

When the strong and weak trigger conditions are met, the strong and weak switching module 20 searches for the WIFI with the optimal signal for switching. When the download triggering condition is met, the download switching module 30 searches for WIFI with an optimal signal and prompts the download rate, and selects switching according to user operation.

In a further embodiment, the electronic device further includes a prompt module 40, configured to prompt a user whether to start a WIFI intelligent switching mode when the WIFI is turned on and a WIFI is successfully connected. The prompt module 40 is also used to implement all the above-mentioned pop-box prompts.
