In order to facilitate understanding of the embodiments of the present invention, a communication network system on which the mobile terminal of the present invention is based is described below.

Referring to fig. 2, fig. 2 is an architecture diagram of a communication Network system according to an embodiment of the present invention, where the communication Network system is an LTE system of a universal mobile telecommunications technology, and the LTE system includes User Equipment (UE) 201, Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) 202, Evolved Packet Core Network (EPC) 203, and IP service 204 of an operator, which are in communication connection in sequence.

Although the LTE system is described as an example, it should be understood by those skilled in the art that the present invention is not limited to the LTE system, but may also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems. Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

An embodiment of the present invention provides a distribution method of a local area network, and fig. 3 is a schematic diagram illustrating an implementation flow of the distribution method of the local area network according to the embodiment of the present invention, and as shown in fig. 3, the method includes the following steps:

step S301, if the time length of the terminal connecting to the current first local area network exceeds a preset time length threshold value, the current signal intensity of the first local area network is obtained.

Here, the terminal may be a mobile phone, a computer, a smart watch, a tablet computer, or the like capable of connecting to a wireless local area network. The duration threshold may be a duration length set by a user, for example, the duration is preset to 5 minutes, and when the duration for the terminal to connect to the current first local area network exceeds 5 minutes, the current signal strength of the first local area network is obtained.

The current signal strength of the first local area network may be the current signal strength of WiFi, wherein the current signal strength of WiFi is related to the following three parameters, 1, the transmission power of the wireless router; 2. wireless transmission loss; 3. the terminal receives the sensitivity. The current signal strength of WiFi can be measured in signal strength units of decibels (dB) and decibel-milliwatts (dBm). Where dB is a value representing a relative value, is a ratio of two powers, and represents only a relative magnitude relationship of the two quantities, without units. When considering how many dB the power of a is larger or smaller than the power of b, the following calculation formula is used: 10log (A power/B power); wherein log (a power/b power) represents a logarithm to the base 10 of the quotient of the a power and the b power. For example, if the first power is twice as large as the second power, 101g (first power/second power) is 10lg2 is 3 dB. That is, the power of A is 3dB greater than the power of B. Conversely, if the power of A is half that of B, the power of A is 3dB less than that of B.

dBm is a unit representing an absolute value of power and is a power level value having a 10log multiple of a milliwatt (mW) relationship, and is calculated as: 10lg power value/(1 mW). Wherein, lg power value represents the logarithm taking the base of 10 to the power value; 1mW represents, 1 mW.

For example, if the transmitted power is 1mW, the value converted in dBm should be: 10lg (1mW/1mW) is 0 dBm; for 40W power, 10lg (40W/1mW) is 46 dBm.

Therefore, the obtaining of the current signal strength of the first local area network may be obtaining the current power of the first local area network first; then the current power is substituted into the formula: and obtaining the current signal intensity of the first local area network by 10lg power value/(1 mW).

Step S302, if the current signal strength is less than the signal strength threshold, disconnecting from the first local area network.

Here, the determination of the signal strength threshold may be: if the terminal runs the R-th application of the Q applications, the consumed flow in a second preset time period is equal to a preset R-th flow threshold value, the signal intensity of a third local area network currently connected with the terminal is obtained, and the signal intensity of the third local area network is used as a preset signal intensity threshold value corresponding to the R-th application; q, R are all natural numbers greater than 0, and R is less than or equal to Q;

and so on, obtaining Q preset signal strength thresholds corresponding to the Q applications.

Then, if the terminal runs Q applications at the same time, taking the maximum value of the Q preset signal intensity threshold values as a signal intensity threshold value; wherein Q is a natural number greater than 0.

For example, four applications are installed in a mobile phone, including a chat tool, a video player, and the like, and it is conceivable that the flow rate of the video player playing the video consumed in the preset time duration is inevitably greater than the flow rate of the chat tool consumed in the preset time duration, so when the mobile phone simultaneously operates the chat tool and the video player, the signal intensity required by the video player is used as the signal intensity threshold. In brief, when the mobile phone simultaneously operates the chat tool and the video player, if the current signal strength of the first local area network is smaller than a signal strength threshold (a preset signal strength threshold corresponding to the video player), the terminal is disconnected from the first local area network.

For an application in the terminal, when the application is in different operation states, the required signal strengths are also different, so that the signal strength corresponding to the operation state in which the application consumes the most traffic within a second preset duration is used as a preset signal strength threshold corresponding to the application, for example, the traffic consumed by a voice chat within a certain duration is obviously smaller than the traffic consumed by a video chat within a certain duration for the same chat tool, so that the signal strength of the corresponding local area network when the chat tool smoothly performs the video chat is used as the preset signal strength threshold of the application.

For a better understanding of the embodiments of the present invention, the first lan and various related art first lans are described herein.

The first Local Area Network may be WiFi, Wireless Local Area Networks (WLAN), Virtual Local Area Networks (VLAN), etc., wherein WiFi complies with the 802.11 standard in radio communication technology. Since Spread Spectrum (SS) technology used in WiFi has very excellent interference rejection capability and has excellent effects while anti-tracking and anti-eavesdropping are required, there is no need to worry that WiFi cannot provide stable network services. The following 4 spreading techniques are commonly used: 1. direct Sequence Spread Spectrum (DS-SS), 2, Frequency Hopping Spread Spectrum (FH-SS), 3, time Hopping Spread Spectrum, 4, continuous wave Frequency modulation. Of the four techniques mentioned above, the first two spread spectrum techniques are common, namely direct sequence spread spectrum and frequency modulated spread spectrum. The latter two are varied from the previous techniques, i.e., time hopping spread spectrum and continuous wave frequency modulation are not usually used alone, and are integrated into other spread spectrum techniques to form a hybrid spread spectrum technique with more dense signals, lower power, and more accurate transmission. Wherein,

1. DS-SS technology is directed to spread the original power spectrum, which is high in power and narrow in bandwidth, over a wide bandwidth, so that the entire transmitted signal can be transmitted with little energy. During the transmission process, single binary data of 0 or 1 is transmitted by using a plurality of fragments, and then the receiving side counts the number of the plurality of fragments to increase the noise interference resistance. For example, to transmit a 1's binary data to the remote, the DS-SS will expand the 1 into three 1's, i.e., 111 for transmission. Even if the original three 1 signals become 011, 101, 110, 111 signals due to interference during transmission, the number of 1 occurrences can be counted to confirm that the data is 1. By transmitting a plurality of identical segments in this manner, it is easier to reduce interference of noise on data and improve the accuracy of data obtained on the receiving side. In addition, because the transmitted spread spectrum signal can greatly reduce the energy during transmission, the signal is hidden in background noise by using the technology in military application, and the enemy can be less apt to monitor the signal and the frequency channel of the communication of the enemy. This is the anti-listening function of the signal hidden by spread spectrum technology.

2. The FH-SS technique is a technique in which the entire bandwidth is divided into not less than 75 frequency channels, and each of the different frequency channels can separately transmit data. When data is transmitted, according to the protocol preset by the transmitting and receiving parties, after a certain time length is transmitted by one frequency channel, the data is synchronously 'jumped' to another frequency channel to continue communication. Fm spread spectrum systems typically hop between several different frequency bands to avoid interference with other transmitted signals in the same frequency band. At each frequency hop, the frequency modulated spread spectrum signal appears as a narrow band signal. If the channel is continuously jumped to the channel with good agreement in the transmission process, the channel can be used as the main technology of electronic anti-tracking in military use. Even if an enemy can monitor signals from a certain channel, the enemy can hardly track the next channel to be jumped to achieve the aim of anti-tracking because the enemy can continuously jump to other channels for communication.

At present, there are two main transmission media adopted by WiFi, namely microwave and infrared. According to different modulation modes, the wireless local area network using microwave as a transmission medium can be divided into a spread spectrum mode and a narrow-band modulation mode. Both microwave and infrared are electromagnetic waves.

One or more of the above WiFi communication technologies are used in this or other embodiments of the invention.

No matter which kind of WiFi spreads the mode, the terminal can both acquire this WiFi's current signal strength, if current signal strength is less than the signal strength threshold value, just in time break the terminal with this WiFi's connection.

In the method for allocating a local area network provided in the embodiment of the present invention, first, if a time period for a terminal to connect to a current first local area network exceeds a first preset time period threshold, a current signal intensity of the first local area network is obtained; then, if the current signal strength is less than a signal strength threshold, the terminal disconnects from the first local area network. Therefore, the local area network with weak signal intensity, which is connected with the terminal for a long time, is timely disconnected by acquiring the signal intensity of the current local area network where the terminal is located, so that the terminal can be connected with the local area network with strong signal intensity.

In other embodiments, before step S302, that is, "if the current signal strength is less than the signal strength threshold, the terminal disconnects from the first local area network", the method further comprises the following steps:

step S321, obtaining an identifier of each application in the T applications currently running by the terminal.

Here, T is a natural number greater than 0, and the identifier of each application may be a name of the application, a socket of the application, and the like.

Step S322, obtaining T corresponding preset signal strength thresholds according to the T application identifiers.

Here, the T preset signal strength thresholds corresponding to the T applications in the terminal may be understood as that the terminal includes a plurality of applications, and signal strengths required when the terminal smoothly runs each application may be the same or different, so that the T applications in the terminal correspond to the T preset signal strength thresholds, and the T preset signal strength thresholds are less than or equal to the T preset signal strength thresholds. For example, a mobile phone includes four applications, and the four applications correspond to four preset signal strength thresholds which are less than or equal to four preset signal strength thresholds and enable the applications to smoothly run; for example, two different chat tools in a handset need the same signal strength, and then the two applications correspond to the same preset signal strength threshold.

In step S323, the maximum value of the T preset signal strength threshold values is used as the signal strength threshold value.

Here, for example, when the terminal simultaneously operates the chat tool and the video tool, it is obvious that the signal strength required for smoothly operating the video tool is greater than the signal strength required for smoothly operating the chat tool, and therefore, the signal strength required for smoothly operating the video tool is used as the signal strength threshold.

In other embodiments, the determining the signal strength threshold of the application installed on the terminal includes two methods:

the method comprises the following steps: and acquiring the identifier of the application installed on the terminal and the attribute of the installed application, and setting a signal intensity threshold value for the installed application according to the attribute of the installed application.

Here, the attribute of the installed application may be a type of the application, a parameter set in the application; the type of the application can be understood as, for example, the type of the installed application can be a chat tool, a video tool, a game, or the like; the parameters set in the application may be understood as: what way the application operates, e.g., is the chat tool chatting either by voice or by text; whether a picture in news is displayed or not in the application of browsing the news; in the video tool, the definition of the played video and the like; obviously, the states of the application during operation are different, and the required signal strength threshold is different. For example, the signal strength required by the chatting tool for chatting in a voice mode is greater than the signal strength required for chatting in a text sending mode. The setting of the signal strength threshold for the installed application according to the attribute of the installed application may be understood as: setting a signal intensity threshold corresponding to the application according to the running state of the installed application; for example, in a news chat application, the signal strength required when the application is set not to display a picture is significantly different from the signal strength required when the application is set to display original pictures.

The second method comprises the following steps: acquiring an identifier of a current application running by the terminal, acquiring a flow value within a preset time length according to the identifier of the current application, and determining a signal intensity threshold value for the current application according to the flow value.

Here, the preset time period may be any time period set by a user, such as 5 minutes; the determining a signal strength threshold for the current application according to the flow value may be: according to the flow value consumed by the application within a preset time (for example, the flow value consumed by the chatting tool within 5 minutes is 10 million), if the consumed flow value is greater than or equal to a preset flow threshold value, determining the signal strength of the currently connected local area network as a signal strength threshold value. For example, if the preset flow threshold is 10 million, and the flow value consumed by the chat tool in 5 minutes when the chat tool is connected to the current local area network is 15 million, which indicates that the signal strength of the current local area network is strong, the signal strength corresponding to the current local area network may be used as the signal strength threshold of the chat tool.

Based on the foregoing embodiment, an embodiment of the present invention further provides a local area network allocation method, and fig. 4 is a schematic flow chart illustrating an implementation of another local area network allocation method according to an embodiment of the present invention, as shown in fig. 4, the method includes the following steps:

step S401, if the time length of the terminal connecting with the current first local area network exceeds a first preset time length threshold value, the current signal intensity of the first local area network is obtained.

Step S402, acquiring a signal intensity threshold value required by Q applications in the terminal in the running state when the Q applications can normally run.

Here, the "acquiring required signal intensity thresholds when Q applications in the terminal in the running state can run normally" may be understood as first acquiring Q preset signal intensity thresholds corresponding to the Q applications in the terminal; then, if the terminal runs Q applications at the same time, taking the maximum value of the Q preset signal intensity threshold values as a signal intensity threshold value; wherein Q is a natural number greater than 0. That is, the signal strength threshold is a signal strength that can ensure that each of Q applications simultaneously running by the terminal can run smoothly.

Step S403, if the current signal strength is smaller than the signal strength threshold, the terminal disconnects from the first local area network.

Here, if the current signal strength is greater than or equal to the signal strength threshold, the process proceeds to step S410.

Step S404, acquiring the parameter information of the first local area network, and adding the parameter information into a second preset parameter library.

Here, the parameter information of the local area network may be a router parameter of a router corresponding to the first local area network, where the router parameter of the router includes at least one of the following parameters: a Service Set Identifier (SSID) of the router, a carrier frequency of the router in normal operation, a channel of the router in normal operation, a protocol standard required for the router in normal operation, and the like. The second preset parameter library comprises N router parameters corresponding to a local area network which can not enable the application of the terminal to normally run, wherein N is a natural number larger than 0. That is to say, the parameter information corresponding to the local area network that cannot enable the terminal to smoothly run the application is stored in the second preset parameter library, when the user connects the local area network again, it is only necessary to compare whether the parameter information of the current local area network is the same as the parameter information in the second preset parameter library, and if the parameter information of the current local area network is the same, the terminal is not connected with the current local area network.

Step S405, when the terminal is in a second local area network, acquiring the current parameter information of the second local area network.

Here, the second local area network is the same as or different from the first local area network; the current parameter information of the second local area network is the router parameter of the router corresponding to the second local area network, that is, the SSID of the router of the second local area network, the carrier frequency in normal operation, the channel in normal operation, the protocol standard required by normal operation, and the like.

Step S406, if the current parameter information is the same as the parameter information in the second preset parameter library, the terminal is not connected to the second local area network.

Here, the current parameter information is the same as the parameter information in the second preset parameter library, which indicates that the signal strength of the second local area network cannot support the terminal to smoothly run the application of the terminal, so that the terminal is not connected to the second local area network.

Step S407, if the current parameter information is different from the parameters in the second preset parameter library, obtaining the current signal strength of the second local area network.

Here, the current parameter information is different from the parameters in the second preset parameter library, indicating two cases:

one situation is: the parameter information of the second local area network is not in the second preset parameter library, but the current signal intensity of the second local area network can support the terminal to smoothly run the application of the terminal.

The other situation is that: the parameter information of the second local area network is not in the second preset parameter library, but the current signal intensity of the second local area network still cannot support the terminal to smoothly run the application of the terminal.

Step S408, if the current signal strength is greater than or equal to a signal strength threshold corresponding to the application of the terminal in a preset signal strength database, the terminal is connected to the second local area network.

Step S409, if the current signal intensity is smaller than the signal intensity threshold, the terminal is not connected with the second local area network, and the parameter information of the second local area network is added into the second preset parameter library.

And step S410, if the current signal strength is larger than or equal to the signal strength threshold value, the terminal is continuously connected with the first local area network.

Step S411, obtaining parameter information of the first local area network, and adding the parameter information to a first preset parameter library.

Here, the first preset parameter library includes parameter information of P local area networks to which the terminal can preferentially connect; p is a natural number greater than 0. That is, the parameter information corresponding to the local area network capable of supporting the terminal to smoothly run the application of the terminal is stored in the first preset parameter library as the network with the priority connection. For example, if the terminal is in the coverage of both the a lan and the B lan, but the parameter information of the B lan is stored in the first database (i.e. the B lan is an application that the terminal has been connected to and can support the terminal to smoothly run the terminal), then the terminal will preferentially connect to the B lan.

In the local area network allocation method provided by the embodiment of the invention, the local area network with weak signal strength connected with the terminal for a long time is timely disconnected by acquiring the signal strength of the current local area network where the terminal is located, so that the terminal can be connected with the local area network with strong signal strength, smooth operation of a plurality of applications in the terminal is ensured, and meanwhile, the situation that the local area network is automatically connected when the terminal only passes through a certain local area network and then is delayed is avoided, and the user experience is improved.

Fig. 5 is a schematic diagram illustrating that the terminal according to the embodiment of the present invention is connected to the local area network and cannot load data, and as shown in fig. 5, the terminal simultaneously runs application 1 and application 2, and although the terminal is displayed in a display area 501 to be connected to WiFi, in a prompt box 502, "WiFi is connected and data loading fails" is displayed. As can be seen from fig. 5, although the terminal is connected to the nearby WiFi through its own WiFi automatic connection function, the WiFi signal strength cannot support the terminal to load data, or the WiFi user sets the WiFi to be WiFi that can be normally used only by requiring short message authentication or requiring a login web page to fill in a user name and a password. Therefore, even if the terminal is connected to the WiFi, data cannot be loaded, that is, the application 1 and the application 2 on the terminal cannot be normally operated. Although the signal intensity of the WiFi cannot support the terminal to load data, the WiFi cannot be automatically disconnected from the electronic device, even if there are other WiFi which can make the terminal smoothly run the application of the terminal nearby, because the terminal is already connected with the WiFi, the terminal cannot be connected with other WiFi, so that in this case, the normal use of the terminal by a user is influenced, and a bad experience feeling is brought to the user.

In order to solve the above problems, embodiments of the present invention improve the WiFi automatic connection function of the terminal itself, so that the terminal can disconnect from the WiFi with weak signal strength in time, and ensure that the terminal is connected to the WiFi with strong signal strength, thereby enabling the terminal to smoothly run various applications in the terminal. First, Applications (APP) in the terminal are acquired, and WiFi signal strength required by smooth operation can be obtained when the terminal is connected to WiFi (for example, Q applications). That is to say, the terminal needs to first determine whether a flow consumed by the terminal in a second preset time period is equal to a preset flow threshold (for example, a preset R-th flow threshold) corresponding to one of Q applications (for example, the R-th application) when the terminal runs smoothly, and if the flow consumed by the terminal in the second preset time period is equal to the preset flow threshold, obtain a signal intensity of a third local area network currently connected to the terminal, and use the signal intensity of the third local area network as a preset signal intensity threshold corresponding to the application (for example, the R-th application); and so on, obtaining Q preset signal strength thresholds corresponding to the Q applications.

If the terminal simultaneously runs Q applications, taking the maximum value of the Q preset signal intensity threshold values as a signal intensity threshold value; wherein Q is a natural number greater than 0.

If the terminal is connected with a certain WiFi and uses one or more applications of the terminal for a long time, the terminal automatically compares the signal strength of the current WiFi with the signal strength threshold corresponding to the one or more applications (for example, if the terminal is using two applications, the terminal automatically compares the signal strength of the current WiFi with the signal strength threshold corresponding to the two applications, where the signal strength threshold is the larger one of the preset signal strength thresholds corresponding to the two applications), and if the signal strength of the current WiFi is smaller than the signal strength threshold, the terminal is automatically disconnected from the WiFi, as shown in fig. 6, the terminal is using an application 1 and an application 2, as can be seen from fig. 6, the application 1 is a video playing application, the application 2 is a music playing application, so that within a certain time, the energy consumed by the smooth running application 1 is larger than the energy consumed by the smooth running application 2, namely, the preset signal intensity threshold value required for smoothly running the application 1 is greater than the preset signal intensity threshold value required for smoothly running the application 2; therefore, the terminal automatically compares the signal intensity of the current WiFi with the signal intensity threshold corresponding to the two applications (i.e. the preset signal intensity threshold required for the smooth running of the application 1), and since the signal intensity of the current WiFi is smaller than the preset signal intensity threshold required for the smooth running of the application 1, the terminal is automatically disconnected from the WiFi, and in the display area 601 of the terminal, the display terminal is not connected with the WiFi, and in the prompt box 602 of the terminal, the "WiFi is disconnected" is displayed.

And after the terminal is disconnected with the WiFi, the terminal acquires the router parameters of the router corresponding to the WiFi and stores the router parameters in a second preset parameter library. Wherein the router parameters at least include: the router comprises a service set identifier of the router, a carrier frequency required by the router during normal operation, a protocol standard required by the router during normal operation, a channel through which the router passes during normal operation and the like. The second preset parameter library comprises N router parameters corresponding to a local area network which cannot enable the application of the terminal to normally run, wherein N is a natural number larger than 0.

When the terminal enters the WiFi coverage area again, the terminal firstly acquires the router parameters of the WiFi, judges whether the router parameters are the same as the router parameters in a second preset parameter library or not, and if the router parameters of the WiFi are the same as the router parameters in the second preset parameter library, the terminal is disconnected with the WiFi.

Here, the terminal re-entering the coverage of the WiFi may be understood as that the terminal re-enters the vicinity of the geographical location of the WiFi, that is, the WiFi which the terminal can search includes but not only the WiFi.

In addition, after the terminal is disconnected from the WiFi, if the flow consumed by the application running on the terminal within a certain time does not exceed a second preset flow threshold, the terminal connects with the mobile data. For example, in fig. 6, the terminal consumes no more than 5 mega (M) of traffic to smoothly run the application 1 in five minutes, and then the terminal is connected with the mobile data. Therefore, the terminal timely disconnects WiFi with weak signal strength, the situation that when a user just passes through some places, the terminal carried with the user is automatically connected with the WiFi in the place can be avoided, even if the signal strength of the WiFi cannot support the terminal to smoothly run the application of the terminal, the terminal and the WiFi are delayed, and the situation that data cannot be loaded even though the WiFi is connected on the terminal is displayed.

And if the terminal judges that the router parameters of the WiFi are different from the router parameters in a second preset parameter library, the terminal judges whether the signal intensity of the current WiFi is greater than a signal intensity threshold value.

If the signal intensity of the current WiFi is greater than the signal intensity threshold, the terminal is connected with the WiFi, as shown in fig. 7, it indicates that the terminal is connected with the WiFi capable of supporting the terminal to smoothly run the application of the terminal, as can be seen from fig. 7, the terminal is using application 1 and application 2, application 1 is a video playing application, application 2 is a music playing application, when the terminal searches for a WiFi signal, first, the terminal obtains the router parameter of the WiFi, and judges whether the router parameter is the same as the router parameter in the second preset parameter library; if the router parameters are different from the router parameters in the second preset parameter library, the terminal judges whether the signal intensity of the current WiFi is greater than a preset signal intensity threshold value required by the smooth running application 1; if the signal intensity of the current WiFi is larger than a preset signal intensity threshold value required by the smooth running of the application 1, the terminal is connected with the WiFi and smoothly runs the application 1 and the application 2; and displaying in a display area 701 that the terminal is in a connection state with the WiFi; and displays "WiFi is connected, data loading is successful" in prompt box 702.

After the terminal is connected with the WiFi, the terminal acquires parameter information of the WiFi and adds the parameter information to a first preset parameter library; the first preset parameter library comprises parameter information of P local area networks which can be preferentially connected by the terminal; p is a natural number greater than 0. In this way, it is possible to realize that, for WiFi to which the terminal has once connected and which can be smoothly used, when the terminal searches for the WiFi again, the WiFi is preferentially connected.

In the embodiment of the invention, the terminal can be disconnected with the WiFi with weak signal strength in time by improving the WiFi automatic connection function of the terminal, so that the condition that the terminal carried with the user is automatically connected with the WiFi in a certain place and is not disconnected after delay when the user only passes the certain place is avoided, and the condition that data cannot be loaded even though the WiFi is connected on the terminal; therefore, the terminal can be connected with the WiFi with strong signal intensity in time so as to ensure the normal operation of the application in the terminal.
