Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.

Example one

The embodiment provides an automatic WiFi connection method, which can be applied to any intelligent terminal device having a wireless communication function and capable of automatically connecting to a WiFi network, such as a mobile phone, a tablet computer, an intelligent bracelet, a personal digital assistant, and an intelligent household appliance such as an air conditioner, a refrigerator, and a television.

As shown in fig. 1, the WiFi automatic connection method provided in this embodiment includes:

step S101: and scanning the AP to acquire all the scanned stored APs.

In a specific application, after the terminal device connects to the corresponding WiFi network through the AP for the first time, the terminal device stores the AP so as to automatically connect to the corresponding WiFi network through the AP when the AP is scanned next time. Storing the AP specifically means storing a network address of the AP and a WiFi password of a WiFi network corresponding to the AP.

In addition, the network environment in which the terminal device is located usually includes more than one WiFi network, and more than one WiFi network is likely to be included, and the terminal device is also likely to store the AP of one or more than one WiFi network in the network environment in which the terminal device is located. Therefore, after scanning for APs, one or more APs may be scanned, and the scanned APs may also include one or more saved APs.

Step S102: and sending a connection request to all the stored APs.

In a specific application, since the terminal device already stores the network address of the AP and the corresponding WiFi password, when the stored AP is scanned, a connection request including the WiFi password may be automatically sent according to the network address of the AP, so as to automatically connect to the corresponding WiFi network through the stored AP. For the AP with the password which is not stored, manual connection is needed when the AP is connected for the first time, and the WiFi password is input; for unsaved privacy-free APs, manual connection is required at the first connection.

It should be noted that, for the stored AP, if the corresponding network address or WiFi password is changed or the storage time is expired, the AP needs to be manually connected according to the connection mode of the unsaved AP.

Step S103: and when all the stored APs are disabled, acquiring the disabled reason of each stored AP.

In a specific application, if an automatic connection to an AP fails, the AP may be disabled, and the reason for the automatic connection failure may be that the signal quality of the WiFi network corresponding to the AP is not good, the number of users (the number of terminal devices) connected to the AP at the same time is large, and a network Address (i.e., an IP Address) or a WiFi password is changed or a storage time is exceeded, where the network Address of the AP is changed or the storage time is exceeded, which may cause a failure in a DHCP (Dynamic Host Configuration Protocol) negotiation.

Step S104: and setting a corresponding automatic connection rule according to the forbidden reason of each stored AP.

In specific application, an automatic connection rule corresponding to the forbidden reason of each AP can be set according to the forbidden reason of each AP, so that the intelligent terminal equipment can be automatically connected to the WiFi network in time, and the network connection efficiency is improved.

As shown in fig. 2, an exemplary correspondence table showing the disabled reason and the automatic connection rule is shown, where reason 1, reason 2, … …, reason n-1 and reason n represent different disabled reasons, rule 1, rule 2, … …, rule n-1 and rule n represent different automatic connection rules, n is greater than 1 and n is a positive integer.

In one embodiment, the WiFi automatic connection method further comprises:

when the stored APs are not scanned, disabling all the stored APs, and returning to the step of scanning APs (i.e. returning to execute step S101);

and stopping scanning when the AP is successfully connected to any saved AP.

In a specific application, if the stored APs are not scanned, re-scanning is required, and when successfully connecting to any stored AP, the terminal device does not need to connect to other APs any more, and can stop scanning, so as to save power consumption unless the user manually inputs a corresponding instruction to trigger the terminal device to re-scan the APs.

In the embodiment, when all the scanned stored APs are disabled, the disabled reason of each stored AP is obtained, and the corresponding automatic connection rule is set according to the disabled reason of each stored AP, so that the intelligent terminal device can be automatically connected to the WiFi network in time, and the network connection efficiency is improved.

Example two

This embodiment is a further refinement of step S104 in the first embodiment on the basis of the first embodiment. As shown in fig. 3, in the present embodiment, step S104 includes:

step S201: and when the reason for forbidding the stored AP is a password error, sending a connection request to the stored AP by taking a preset time length as a period.

In a specific application, the preset time length may be set according to actual needs, for example, any integer or non-integer time length such as 3S (seconds), 5S, or 8S. Sending a connection request to the stored AP by using a preset time length as a period, specifically, sending a connection request once within each preset time length or once every preset time length, where a frequency of sending the connection request is sent once every preset time length, for example, when a duration of the preset time length is 5S, a frequency of sending the connection request is sent once every 5S.

Step S202: setting the saved AP to be permanently disabled while the saved AP remains disabled after a first preset number of cycles.

In a specific application, after a plurality of connection requests are continuously sent, if the saved AP is still disabled, the saved AP is set to be permanently disabled. The first preset number refers to the number of times of sending the connection request continuously, and the first preset number may be set according to actual needs, for example, any integer such as 3, 5, or 8. The fact that the saved AP is still disabled means that after the connection request is sent to the AP, the connection is still failed due to a password error, so that the AP is disabled.

Step S203: and when the password carried by the connection request sent to the stored AP is changed, setting the stored AP to be available.

In a specific application, if the user modifies the WiFi password carried in the connection request sent to the AP, the AP is temporarily set to be available, and step S201 is proceeded to.

Step S204: and when receiving an instruction of sending a connection request to the saved AP, which is input by a user, setting the saved AP to be available.

In a specific application, if the user manually inputs a corresponding instruction to resend the connection request to the AP, the AP is temporarily set to be available, if the connection still fails, the AP is set to be permanently disabled again, and the process proceeds to step S203 or S204.

In this embodiment, when the reason for disabling the AP is a password error, the AP is periodically sent to the AP with a preset time length as a period, and when a first preset number of connection requests are continuously sent to the AP and the AP is still disabled, the AP is set to be permanently disabled, and is not set to be available again until a user modifies a password or manually triggers connection, so that the terminal device can be prevented from continuously sending a connection request to the AP, thereby reducing power consumption.

EXAMPLE III

This embodiment is a further refinement of step S104 in the first embodiment on the basis of the first embodiment. As shown in fig. 4, in the present embodiment, step S104 includes:

step S301: and acquiring the current time point when the reason for forbidding the stored AP is that the number of users exceeds the standard.

In a specific application, the number of users specifically refers to the number of terminal devices connected to the same AP, and the number of users exceeding the standard refers to the number of users connected to the same AP exceeding the maximum user capacity that the AP can support. Theoretically, the user capacity of an AP is not limited, and it depends only on the capacity of the network address range allocated to the AP. However, from the practical network rate, the number of users that can be borne by an AP is limited, and generally the number of home APs is no more than 20-30, and the number of home APs is no more than 100 at the enterprise level. If the number of users is too large, the available bandwidth of each user is too small, thereby reducing the network communication rate.

In a specific application, the current time point is a specific time when the reason for disabling the stored AP is that the number of users exceeds the standard. For example, the current time point is twelve o 'clock at noon (i.e., 12: 00) or eight o' clock at night (i.e., 20: 00).

Step S302: and sending a connection request to the stored AP by taking the time length corresponding to the time period as a cycle according to the time period of the current time point.

In a specific application, the connection request may be periodically sent to the AP by taking the corresponding time length as a cycle according to a specific time period of the current time point. The number of users connected to the same AP in different time periods is different, and generally, for a WiFi network in an office, the number of users connected to the same AP is large in a peak time period during work, and at this time, the number of users connected to the AP is likely to exceed the standard, so that the AP is disabled; in the off-peak time period during work, the number of users connected to the same AP is small, and it is easier to successfully connect to the WiFi network corresponding to the AP. Therefore, a longer time length can be set in the peak period, and a shorter time length can be set in the low peak period.

In specific application, 24 hours a day can be divided into a plurality of different time periods, different time lengths are taken as periods according to different time periods of the current time point, and connection requests are sent to the forbidden APs due to the fact that the number of users exceeds the standard, so that connection power is improved, and power consumption is reduced. For example, a 24 hour day may be divided into 8: 00-18: peak period of 00, 18: 00-21: 00 middle peak and 21: 00-8: 00 the peak period, the connection request is sent in 30 minutes as a cycle in the peak period, the connection request is sent in 15 minutes as a cycle in the peak period, and the connection request is sent in 5 minutes as a cycle in the peak period. The specific time division manner and the setting of the time length of the period can be determined according to actual needs.

In one embodiment, the WiFi connection method further includes:

acquiring the number of users connected to the stored AP;

sending a connection request to the stored AP by taking the time length corresponding to the number of the users as a period; wherein the number of users is positively correlated with the length of time.

In a specific application, the more the number of users connected to the AP, the greater the probability of connection failure, the more the users are, the longer the time interval for sending connection requests should be, and the less the number of users, the shorter the time interval for sending connection requests should be, so as to increase the connection power and reduce the power consumption.

Example four

This embodiment is a further refinement of step S104 in the first embodiment on the basis of the first embodiment. As shown in fig. 5, in the present embodiment, step S104 includes:

step S401: and when the reason for disabling the stored AP is that the signal quality problem exists, detecting the signal strength of the stored AP.

In a particular application, when the signal quality of an AP is poor or unstable, a connection failure may result, such that the AP is disabled.

Step S402: according to the signal intensity, a connection request is sent to the stored AP by taking the time length corresponding to the signal intensity as a period; wherein the length of time is inversely related to the magnitude of the signal strength.

In a specific application, when the signal strength of the AP is strong, a relatively short time length may be set, so that the terminal device may send a connection request to the AP again after a short time length after failing to automatically connect to the AP, so as to connect to the AP in time, shorten the connection time, and improve the connection efficiency. When the signal strength of the AP is weak, a relatively long time duration may be set, so as to save electric energy consumed by the terminal device to frequently send a connection request when the signal quality is not good, and reduce power consumption. For example, when the signal strength is A, B, C, D, the corresponding time lengths are a, b, c, and d; wherein A is more than B and more than C and D, and a is more than B and less than C and less than D. By inversely correlating the magnitude of the signal strength with the length of the time period, the time period can be adaptively adjusted according to the magnitude of the signal strength.

In one embodiment, step S402 includes:

setting the time length to a first time when the signal strength is within a weak signal strength range;

setting the time length to a second time when the signal strength is within a strong signal strength range; wherein the lower limit value of the strong signal strength range is greater than the upper limit value of the weak signal strength range, and the length of the first time is greater than the length of the second time.

In a specific application, the weak signal strength range and the first time can be set according to actual needs, for example, the weak signal strength range can be set to [ -120db, -85db ], and the first time can be set to 30S.

In a specific application, the strong signal strength range and the second time can also be set according to actual needs, for example, the strong signal strength range can be set to (-85db, -30 db), and the second time can be set to 20S.

It should be understood that the weak signal strength range and the strong signal strength range need not be two continuous ranges of values, but may be two discontinuous ranges of values. For example, the weak signal strength range may be set to [ -120db, -80db ], and the strong signal strength range may be set to (-75db, -30db ].

In a specific application, the disabling time may also be set according to more than two different signal strength ranges, and there is no overlapping portion between the different signal strength ranges, and the number and the range size of the specific signal strength ranges may be set according to actual needs. For example, the disable time may be set based on four signal strength ranges, a weak signal strength range, a second strong signal strength range, and a strong signal strength range. Correspondingly, in one embodiment, step S104 includes:

setting the time length to be a third time when the signal strength is within a second weak signal strength range;

setting the time length to be fourth time when the signal intensity is in a second strong signal intensity range;

setting the time length to a second time when the signal strength is within a strong signal strength range;

wherein, the lower limit value of the strong signal strength range is larger than the upper limit value of the second strong signal strength range, the lower limit value of the second strong signal strength range is larger than the upper limit value of the second weak signal strength range, the lower limit value of the second weak signal strength range is larger than the upper limit value of the weak signal strength range, and the first time is larger than the third time and larger than the fourth time and larger than the second time.

Specifically, in one example, the weak signal strength range, the next strong signal strength range, the strong signal strength range, and the corresponding disable times may be set to: [ -120db, -100db ], (-100db, -85db ], (-85db, -65db ], (-65db, -30db ], and 30S (seconds), 25S, 20S, 15S.

Similarly, the four signal strength ranges are not necessarily continuous ranges, but may be four discontinuous ranges. For example, the weak signal strength range, the next strong signal strength range, the strong signal strength range may be set to: [ -120db, -100db ], [ -95db, -85db ], [ -80db, -65db ], [ -60db, -30db ].

Based on the above principle of setting the signal strength range and the disable time, in one embodiment, step S402 may further include:

setting the time length to be a fifth time when the signal intensity is within a middle signal intensity range;

wherein the lower limit of the strong signal strength range is greater than the upper limit of the medium signal strength range, the lower limit of the medium signal strength range is greater than the upper limit of the weak signal strength range, and the first time is greater than the fifth time and is greater than the second time.

In one embodiment, step S402 includes:

extending the length of time when the signal strength decreases;

and when the signal intensity is increased, shortening the time length.

In a specific application, since the signal strength of an AP is not fixed, but changes with the change of the signal strength of the ethernet network to which the AP is connected, after the corresponding time length is set according to the saved signal strength of the AP, when the signal strength of the AP changes, the time length should be adaptively extended or shortened according to the change of the signal strength.

In one embodiment, after step S402, the method returns to step S401 to detect the saved signal strength of the AP again, so as to determine whether the current signal strength changes.

Likewise, in one embodiment, step S402 further includes:

when the signal strength is changed from being in a weak signal strength range to being in a strong signal strength range, the time length is changed from a first time to a second time;

and when the signal strength is changed from being in the strong signal strength range to being in the weak signal strength range, the time length is modified from the second time to the first time.

In this embodiment, when the reason for disabling the stored AP is a signal quality problem, the signal strength of the stored AP is detected, and the interval time length for sending the connection request is adaptively modified according to the change of the signal strength of the AP, so that the interval time length for sending the connection request can be dynamically adjusted according to the change of the signal strength of the AP, thereby maximally improving the automatic connection efficiency and saving power consumption.
