Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

Specifically, please refer to fig. 1, which illustrates a schematic diagram of a WIFI network access scenario provided in an embodiment of the present application. As shown in fig. 1, a plurality of WiFi access points, such as a first WiFi access point 201, a second WiFi access point 202, and a third WiFi access point 203 in fig. 1, are included within the network coverage of the mobile terminal 100. The mobile terminal 100 and any WiFi access point need a channel to connect, that is, each WiFi access point is located on a channel, and different WiFi access points may be located on different channels or on the same channel.

When the mobile terminal 100 enters the network coverage area, it starts to scan the WiFi access point in the network coverage area, specifically, the system of the mobile terminal sends a scan request, and after the WiFi chip or other underlying network modules of the mobile terminal receive the scan command, it scans according to the preset channel scan sequence, for example, scan the channels of the common channels 1, 7, and 13 first, and then scan other channels that are not common.

Specifically, as shown in fig. 2, a WiFi network list interface is displayed in the interface, and the WiFi control switch has a function of turning on or off a WiFi network. For example, the WiFi control switch may control the power of the WiFi module to be turned on or off, and when the user clicks the WiFi on the mobile phone, the WiFi module is powered on to operate, and a driver of the WiFi is loaded correspondingly.

After the WiFi control switch is turned on, a WiFi access point near the mobile terminal 100 is searched in a Scanning (Scanning) manner, and a scanned result is displayed in the WiFi network list interface, wherein the Scanning may be performed in an active Scanning manner or a passive Scanning manner. After the scanning is completed, Authentication (Authentication) needs to be performed on the scanned wireless access hotspot. For example, the authentication may be performed by open system authentication, shared key authentication, or pre-authentication. For example, the WiFi access point that the mobile terminal 100 successfully authenticates is the first WiFi access point. After the authentication is completed, the mobile terminal 100 is associated with the access point to obtain full access to the network, so that the mobile terminal 100 successfully connects to the internet through the access point.

Each WiFi access point corresponds to an electronic device, which can establish a communication connection with an external device such as a mobile terminal, for example, has a WiFi module, and can perform a WiFi connection with the mobile terminal, for example, the electronic device is a router, and one router may have a plurality of WiFi access points, so that one router may be connected with a plurality of mobile terminals and may be allocated on different channels, and specifically, the correspondence between the channels of the router and the mobile terminals is shown in table 1 below.

TABLE 1

Channel with a plurality of channels	Is connected withMobile terminal (2)
		6	Id1，Id12
7	Id11，Id3
		3	Id4
4	Id17

As can be seen from table 1 above, the number of mobile terminals currently connected by the router, and the channel on which each connected mobile terminal is located, and the identity of the connected mobile terminal, e.g., Id1, where the identity of the mobile terminal may be the MAC address or device number of the mobile terminal.

At present, the channel of the router may be manually set by the user, for example, fixed to 6 channels for connection, and then the mobile terminal may be connected to the router through 6 channels, or of course, the router may allocate the connected channels to different mobile terminals when a plurality of mobile terminals need to be connected.

However, the inventor has found in research that when allocating channels to different mobile terminals in a network environment, it is more likely that the mobile terminal connected first is allocated to a better channel, and the mobile terminal connected later is allocated to a bad channel, which may cause old users who are often connected to the router to be unable to allocate to a better channel, so that the allocation of channels to the electronic device is not reasonable enough in consideration of the situation of the mobile terminal.

Therefore, in order to solve the above-mentioned defects, an embodiment of the present application provides a communication connection method, which is applied to an electronic device, specifically, the electronic device may be a router, and may also be a mobile terminal capable of opening a WiFi hotspot, and a WiFi module of the mobile terminal can be used as a router at this time, and in the embodiment of the present application, for example, the electronic device is used as a router to describe the embodiment of the present application, then the method may be used to solve the problem that a channel configuration of the router is not reasonable, as shown in fig. 3, the method includes: s301 to S305.

S301: determining an error vector magnitude for each channel of the electronic device.

An Error Vector Magnitude (EVM) is a Vector difference between an ideal Error-free reference signal and an actually transmitted signal at a given time, and is used for measuring an amplitude Error and a phase Error of a modulated signal, and the EVM specifically indicates a proximity degree of an IQ component generated when a receiving terminal demodulates the signal and an ideal signal component, and is an index for considering the quality of the modulated signal. The smaller the EVM, the better the signal quality of the channel.

As an implementation manner, after the router is turned on, the supported channels are scanned channel by channel according to a preset channel scanning order, and at this time, EVM values of all channels are obtained and stored.

S302: and acquiring the range of the error vector amplitude corresponding to the mobile terminal.

The error vector range of the mobile terminal may be a range of error vector magnitudes of channels that can be used by the mobile terminal, or may be a range of error vector magnitudes of channels that are allowed to be used. For example, if the EVM value ranges from-30 to-15, it indicates that the EVM value that can be used by the mobile terminal is-30 to-15.

The error vector magnitude range of the mobile terminal may be set by a user according to a requirement, or may be set according to a policy of a router, for example, in a network environment where the router is located, several mobile terminals are frequently connected to the router in a communication manner, and may be considered as a common user of the environment where the router is located, a channel with good signal quality is prone to be allocated to the mobile terminal, and thus, the router may acquire the connection times of each mobile terminal in a preset communication time period, for example, in a preset communication time period, and the identifiers of all mobile terminals establishing communication connection, thereby acquiring the connection times of each mobile terminal in the preset communication time period, and set the error vector magnitude for the mobile terminal corresponding to the times according to the connection times, where the error vector magnitude range includes a first threshold and a second threshold, and the first threshold is smaller than the second threshold, the range of the error vector magnitude is the range between the first threshold and the second threshold, the higher the number of connections, and the smaller the first threshold, that is, the higher the number of connections, the higher the signal quality of the usable channel, so that the mobile terminal with the higher number of connections can be preferentially configured with the channel with the better signal quality.

In addition, each mobile terminal corresponds to identity information, which may be information used to indicate the identity of the mobile terminal, such as the MAC address or device ID of the mobile terminal. Specifically, the router may acquire the identity information of the mobile terminal when the mobile terminal is connected with the router, or when the mobile terminal scans the router. The specific implementation manner of obtaining the error vector magnitude range corresponding to the mobile terminal is as follows: acquiring identity information of the mobile terminal; and searching the error vector amplitude range corresponding to the mobile terminal according to the corresponding relation between the preset identity information and the error vector amplitude range.

After the identity information of the mobile terminal is acquired, an error vector magnitude range is configured for the mobile terminal corresponding to the identity information, and the configuration mode may be set according to the current connection number of the router and a channel where each mobile terminal connected to the router is located, for example, the number of the mobile terminals connected to the current router is 6, and the mobile terminals are equally distributed in the channel 6, and the signal quality of the channel 6 is the best, so that the channel 6 is prevented from being continuously connected with too many mobile terminals at this time, and a channel other than the channel 6 can be configured for the mobile terminal to be configured with the channel.

Of course, the channel can also be configured according to the priority of each mobile terminal, and some mobile terminals with higher priority can configure a better channel. Specifically, identity information of the mobile terminal is acquired; determining the priority corresponding to the mobile terminal according to the corresponding relation between the preset identity information and the priority; and setting an error vector magnitude range for the mobile terminal according to the priority of the mobile terminal.

The priority corresponding to the identity information may be set according to the number of connections in the preset time period, for example, the higher the number of connections, the higher the priority, or may be set according to the number of data transmissions in the preset time period, for example, the higher the number of data transmissions, the higher the priority.

Specifically, the router is preset with a priority corresponding to each identity information, for example, the router may be stored in a correspondence table between the identity information and the priority, and the correspondence table stores a plurality of identity information and the priority corresponding to each identity information. Then as an embodiment, the correspondence of identity information to priority and the correspondence of error vector magnitude range to identity information may be stored together as shown in table 2 below:

TABLE 2

Identity information	Error vector magnitude range	Priority level
			ID1	[-30,-10]	J1
ID2	[-20,-10]	J2
			ID3	[-15,-10]	J3

As shown in table 2 above, J1, J2, and J3 represent different priorities, and as an embodiment, the smaller the number following "J" the higher the priority. Then J1 is the highest priority, J2 is the next highest, and J3 is the lowest of J1, J2, and J3. It can be seen that the higher the priority, the smaller the first threshold in the corresponding error vector magnitude range, i.e. the better the signal quality channel can be used.

And determining the identity information of the mobile terminal according to the corresponding relation between the error vector magnitude range and the identity information, and then determining the priority corresponding to the identity information of the mobile terminal.

S303: and determining the channel with the error vector amplitude within the error vector amplitude range in each channel as a candidate channel.

After the router acquires the error vector magnitude of each supported channel and also acquires the error vector magnitude range of the mobile terminal, the error vector magnitude of each channel of the router and the error vector magnitude range of the mobile terminal are subjected to, for example, channel within the range is found as the candidate channel.

Specifically, assuming that signals supported by the router are channel a, channel B, channel C, and channel D, the value of the EVM for each channel is as shown in table 3 below.

TABLE 3

Identification of channels	EVM value
		Channel A	-30
Channel B	-15
		Channel C	-9
Channel D	-10

And the error vector magnitude range of the mobile terminal is [ -30, -15], the candidate channels that can be determined are channel a and channel B, i.e., the EVM value corresponding to channel a is-30, and the EVM value corresponding to channel B is-15, both of which are within the error vector magnitude range.

S304: and determining one channel from the alternative channels as a target channel.

After the candidate channels are determined, it means that all channels in the candidate channels can be configured to the mobile terminal, and then one channel can be randomly selected from the candidate channels as a target channel.

In addition, a target channel may also be selected according to the number of connections of the channel or the data transmission amount corresponding to the channel, for example, the data transmission amount of each channel in each candidate channel within a preset transmission time, so that the channel with the smallest data transmission amount is taken as the target channel.

S305: and controlling the electronic device and the mobile terminal to establish connection through the target channel.

Specifically, the electronic device and the mobile terminal are controlled to establish connection through the target channel, where the electronic device may not be connected with the mobile terminal at present, and when the electronic device obtains the connection request of the mobile terminal, the electronic device returns an identifier of the channel, that is, an identifier of the target channel, so that the mobile terminal is connected with the router through the target channel.

Of course, after the router has been connected to the mobile terminal, the electronic device and the mobile terminal may reestablish the connection through the target channel according to the determined target channel. Specifically, the router sends a reconnection request, where the reconnection request includes an access point identifier, an IP address, and a channel identifier of the router, and after the mobile terminal obtains the reconnection request, the mobile terminal parses the request to obtain the identifier of the router and the channel identifier, so that the mobile terminal can know that the identifier of the router is scanned in a channel corresponding to the channel identifier, and after the router is scanned, the mobile terminal sends a connection request to the router, and the router and the mobile terminal reestablish a connection.

However, considering that if the EVM value of the target channel is poor, the mobile terminal needs to scan the router on the target channel more time, and a scanning time can be set in the reconnection request, the mobile terminal can scan the channel according to the scanning time, and it is avoided that the mobile terminal cannot scan the router on the target channel due to inaccurate scanning time, which results in disconnection between the router and the mobile terminal.

Thus, the router may set a scan time for the target channel, and in particular, determine the scan time for the target channel based on the error vector magnitude of the target channel.

As an embodiment, the larger the EVM of a channel is, the worse the signal quality of the channel is, the longer the scanning time is, the scanning time may be increased for those channels with poor signal quality, because the poor signal quality of the channel may cause the transmission rate of the signal to be too low, and cause the transmission rate of the signal of the channel to be too slow, which further causes the scanning process to be slow, and requires a longer time, the scanning time of the channel needs to be increased, so that each channel may be scanned more comprehensively.

Therefore, in determining the EVM value of the channel, a scanning time may be configured for the channel according to the EVM value, that is, a time may be manually configured for each channel, and of course, a corresponding relationship between an error vector magnitude and a scanning time may also be set, specifically, the corresponding relationship may be preset, and the corresponding relationship includes a plurality of error vector magnitudes and scanning times corresponding to each error vector magnitude, specifically, as shown in table 4.

TABLE 4

EVM value	Time of scan
		-30	20s
-25	25s
		-16	30s
-19	28s

As can be seen from the above table, the smaller the EVM value, the shorter the corresponding scan time, and the larger the EVM value, the longer the corresponding scan time. Thus, when the EVM value of the target channel is determined, the scanning time corresponding to the error vector magnitude of the target channel can be found according to the correspondence illustrated in table 1, for example, if the error vector magnitude of the target channel is-30, the corresponding scanning time is 20 s.

The corresponding relationship may be set by a user according to a requirement, and as an embodiment, the corresponding relationship may be obtained by testing before the router leaves a factory, specifically, an error vector magnitude of each WiFi channel in the plurality of WiFi channels supported by the router is detected; and establishing a corresponding relation between the error vector amplitude and the scanning time according to the detected error vector amplitude of each WiFi channel and storing the corresponding relation.

Before the router leaves a factory, testing the EVM value of each channel supported by the router in a pre-established testing environment to obtain the EVM value of each supported channel, then establishing a network environment, wherein the network environment comprises a plurality of WiFi access points which are distributed on different channels, so that at least one WiFi access point is distributed on each channel, then continuously debugging the scanning time of each channel to ensure that all the access points distributed on the channel can be scanned, so that the corresponding relation between the error vector amplitude and the scanning time can be established by testing the error vector amplitude of each WiFi channel, and then storing the preset corresponding relation so that the preset corresponding relation can be used after the router goes wrong.

As an embodiment, the error vector magnitude is positively correlated to the scan time for the sake of comprehensiveness of the scan of the channel. The positive correlation means that the larger the magnitude of the error vector, the longer the scanning time. Therefore, when the error vector magnitude is larger, namely the signal quality of the channel is poorer, the scanning time of the channel can be increased, so that each channel can be scanned more comprehensively to obtain all access points distributed on the channel.

Referring to fig. 4, an embodiment of the present application provides a communication connection method for solving an unreasonable channel configuration of a router, and as shown in fig. 4, the method includes: s401 to S405.

S401: determining an error vector magnitude for each channel of the electronic device.

S402: and acquiring the range of the error vector amplitude corresponding to the mobile terminal.

S403: and determining the channel with the error vector amplitude within the error vector amplitude range in each channel as a candidate channel.

S404: and selecting the channel with the minimum error vector amplitude as a target channel from the alternative channels.

S405: and controlling the electronic device and the mobile terminal to establish connection through the target channel.

Specifically, after determining the error vector magnitude of each of a plurality of channels supported by the router, the plurality of channels are ordered according to the error vector magnitude of each of the channels to obtain a channel error vector magnitude sequence.

For example, the channels in table 3 may be reordered in order of the EVM values from large to small, or in order of the EVM values from small to large, in this embodiment, table 3 is ordered according to the EVM value of each channel and in order of the EVM value from small to large, and then table 5 is changed to table 3.

TABLE 5

Identification of channels	EVM value
		Channel A	-30
Channel B	-15
		Channel D	-10
Channel C	-9

The obtained channel error vector magnitude sequence is [ channel a, channel B, channel C, channel D ], and the channel with the largest EVM can be clearly determined according to the sequence. According to the above embodiment, if the determined candidate channels are channel a and channel B, the EVM value of channel a is determined to be the minimum, and the channel a is taken as the target channel.

In addition, when the number of the channels connected is excessive, the channels are not crowded too much, when the channel with the largest error vector magnitude is determined, the current number of the channels connected is obtained, whether the current number of the channels connected is larger than a preset value or not is determined, if the current number of the channels connected is larger than the preset value, the channel with the second smallest error vector magnitude is selected until the channel with the current number of the channels connected smaller than or equal to the preset value is found and is used as a target channel.

Referring to fig. 5, an embodiment of the present application provides a communication connection method for solving an unreasonable channel configuration of a router, and as shown in fig. 5, the method includes: s501 to S506.

S501: determining an error vector magnitude for each channel of the electronic device.

S502: and acquiring the range of the error vector amplitude corresponding to the mobile terminal.

S503: and determining the channel with the error vector amplitude within the error vector amplitude range in each channel as a candidate channel.

S504: and determining a channel with the error vector amplitude smaller than a preset value in the alternative channels as a channel to be determined.

Specifically, a preset value is set for the range of the error vector magnitude belonging to the mobile terminal, and is used for configuring the channel with the error vector magnitude smaller than the preset value as a target channel to the mobile terminal, and the preset value can be obtained by statistics according to the value of the error vector magnitude of the current channel with higher signal quality. Therefore, the channel with the error vector magnitude larger than the preset value is marked as the channel to be determined.

S505: and determining the target channel from the channels to be determined.

Determining a channel as a target channel from the channels to be determined, specifically, randomly selecting a channel as the target channel, but considering that if the number of connections of the channels is too large, normal use may be affected, and data cannot be sent and received, therefore, a specific implementation manner of determining the target channel from the channels to be determined may be:

acquiring the terminal connection number of each channel in the channels to be determined; and determining the target channel according to the terminal connection number of each channel in the channels to be determined.

Specifically, the number of connections per channel of the router is recorded, and as shown in table 1 above, after the number of connections per channel is determined, the target channel is determined by the number of connections per channel. Specifically, it may be determined that a channel with the smallest number of connections in all current channels is a target channel, and it may be ensured that after the channel is taken as the target channel, a mobile terminal is connected to a router through the channel, and is less likely to jam than when other channels are used, for example, if the determined channels to be determined are channel 6, channel 4, and channel 3, the number of connections of channel 6 is 5, the number of connections of channel 4 is 4, and the number of connections of channel 3 is 3, the target channel determined this time is channel 3, and after the mobile terminal is connected to the router through the channel 3, the number of connections of repair channel 3 is 4.

In addition, if the connection number of a plurality of channels (wherein a plurality of channels are defined as being greater than or equal to 2) is the same when the channel with the minimum connection number is selected from the channels to be determined, one channel is randomly selected from the channels with the same connection number as a target channel, in addition, the time point and the times of selecting the channel as the target channel each time can be recorded, and if the channels with the same connection number are a plurality of channels, the channel of which the target channel is selected last time from the channels with the same connection number is determined according to the record to be used as the target channel of the current time, so that the data of the channel for establishing the communication connection can be directly used at the current time without being deleted because the data are used last time.

S506: and controlling the electronic device and the mobile terminal to establish connection through the target channel.
