Description

Router side WiFi switching method and router

Technical field

The present invention relates to electronic communication, and in particular to a router side WiFi switching method and a router.

Background technique

With the rapid development of smart terminals and tablets, more and more users will use smart terminals and tablets to get information, play games and even work, while traditional PCs such as laptops and desktops are used less frequently. It is.

A very important advantage of smart terminals and tablets is that they can be moved to any location (the desktop is difficult to move, the laptop is generally not as light as the smart terminal and tablet), which further facilitates the user. usage of.

Another factor that supports the popularity of tablets and smart terminals is the wireless network, which, thanks to wireless network support, ensures that users can still access the Internet while moving their tablets and smart terminals. Among them, the wireless network has a cellular network and a wireless fidelity (WiFi) network. Among them, since the cellular network is provided by the mobile operator, it is basically based on the flow rate, and the use cost is relatively high. So unless necessary, more users may use the WiFi network to access the Internet. Only one wireless router is needed, and users can extend a WiFi network based on the wired network. The cost of using the wired network is much lower than that of the cellular. Network, so many users will use the WiFi network where there is coverage of the WiFi network, thus reducing the cost of the network.

WiFi networks use the 802.11 series of protocols, including 802.11a, 802.11b, 802.11g, 802.11n and 802.11ac, etc. Relatively speaking, the newer versions support higher rates. The current mainstream WiFi usage is 2.4Ghz and 5Ghz, also known as 2.4G WiFi and 5G WiFi. Among them, 5G WiFi mainly refers to 802.11n and 802.11ac. It should be noted that although 802.11a can also work in 5Ghz, since the maximum rate supported by 802.11a is small, the so-called 5G WiFi does not include 802.11a.

Nowadays, many smart terminals and tablets support both 5G WiFi and 2.4G WiFi, while more and more wireless routers supporting 5G WiFi and 2.4G WiFi are also available. If a router supports both 5G WiFi and 2.4G WiFi, you can set up 5G WiFi network and 2.4G WiFi network at the same time. Network, in order to facilitate users to access different networks according to different needs. Among them, the bandwidth supported by 2.4G WiFi is relatively narrow, but because the frequency of 2.4G is relatively small, the attenuation is small and the coverage is wide; while the bandwidth supported by 5G WiFi is wider, in other words, the speed is fast, but because The frequency is relatively high, the attenuation is large, and the coverage is relatively small.

Many existing smart terminals and tablets support both 5G WiFi and 2.4G WiFi, but generally only one of them is used, and the network connected may not be the most suitable one. Can not take advantage of 5G WiFi and 2.4G WiFi.

Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, instead of All embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The video call method provided by the embodiment of the present invention is described first. FIG. 1 is a flowchart of a router side WiFi handover method according to an embodiment of the present invention. The embodiment describes a process flow of a router, where the router provides a 5G WiFi network at the same time. And the ability of 2.4G WiFi network. As shown in FIG. 1, this embodiment includes:

101. The router detects a signal strength of the first WiFi network that the terminal currently accesses, where the first WiFi network is a 2.4G WiFi network or a 5G WiFi network.

It should be noted that, in the embodiment of the present invention, the signal strength of the first WiFi network refers to the signal strength of the first WiFi network where the terminal is currently located. Similarly, the signal strength of the second WiFi network in the embodiment of the present invention is specific. It refers to the signal strength of the second WiFi network where the terminal is currently located.

In an embodiment, the signal strength of the first WiFi network detected by the router may be fed back by the terminal. In another implementation manner, the router may estimate the signal strength of the first WiFi network where the terminal is located according to the channel condition of the first WiFi network accessed by the terminal, where the specific estimation manner may adopt a prior art, for example, The estimation may be performed according to the situation of the packet loss rate of the terminal, and the specific estimation manner is not repeatedly described in the embodiment of the present invention.

The signal strength may be any value of a parameter capable of representing the signal strength, and may be, for example, a signal-to-noise ratio (SNR), a signal power value, a signal attenuation value, and the like. The embodiment of the present invention does not limit the value of which parameter is specifically used as the signal strength, because the value of which parameter is used as the signal strength does not affect the implementation of the embodiment of the present invention.

102. The router determines, according to a relationship between a signal strength of the first WiFi network and a signal strength of the second WiFi network, a signal strength of the second WiFi network where the terminal is currently located.

The second WiFi network is a 2.4G WiFi network or a 5G WiFi network, and the first WiFi network and the second WiFi network have a 2.4G WiFi network and a 5G WiFi network. That is, if the first WiFi network is a 2.4G WiFi network, the second WiFi network is a 5G WiFi network; conversely, if the first WiFi network is a 5G WiFi network, the second WiFi network is a 2.4G WiFi network.

Wherein, the foregoing detection may be periodic, for example, the router automatically starts every certain interval. The signal strength of the first WiFi network is detected, and the signal strength of the second WiFi network is determined according to the signal strength of the first WiFi network. Certainly, the foregoing detection may also be triggered by an event. For example, when the router detects that the signal strength of the first WiFi network currently accessed by the terminal is lower than a certain threshold, the signal strength is determined according to the signal strength of the first WiFi network. The signal strength of the WiFi network is not limited by the specific determination timing in the embodiment of the present invention.

Wherein, in an embodiment, the relationship between the signal strength of the first WiFi network and the signal strength of the second WiFi network includes a relationship between a signal strength of the 2.4G WiFi network and a signal strength of the 5G WiFi network. In a possible implementation manner, the relationship between the signal strength of the 2.4G WiFi network and the signal strength of the 5G WiFi network includes: when the signal strength of the 2.4G WiFi network is greater than 60%, the signal strength ratio of the 5G WiFi network is 2.4. The signal strength of the G WiFi network is 10% lower; when the signal strength of the 2.4G WiFi network is between 30% and 60%, the signal strength of the 5G WiFi network is 1/2 of the 2.4G WiFi network; when the 2.4G WiFi network is When the signal strength is less than 30%, the signal strength of the 5G WiFi network is 1/3 of that of the 2.4G WiFi network. It should be understood that the specific numbers listed above are merely exemplary examples, and may be adjusted according to specific needs in practical applications. The specific embodiments of the present invention are not limited to the specific numbers.

It can be understood that the relationship between the signal strength of the 2.4G WiFi network and the signal strength of the 5G WiFi network provided by the embodiment of the present invention is only a simple calculation method provided by the embodiment of the present invention, and the calculation result is as follows. The basis of the switching between the 2.4G WiFi network and the 5G WiFi network does not mean that the signal strength between the 2.4G WiFi network and the 5G WiFi network actually has such a relationship in practical applications. In practical applications, the 2.4G WiFi network The relationship between the signal strength and the 5G WiFi network is much more complicated than that in the above embodiment. For example, the relationship between the signal strengths is also related to the length of the linear distance between the location of the terminal and the location of the router. Far, the greater the attenuation, and the attenuation of the 5G WiFi network is faster than that of the 2.4G WiFi network; the location of the terminal is related to the number and type of obstacles between the location of the router, and the more the obstacles, the faster the attenuation, Metallic obstacles can cause attenuation of WiFi signals more than non-metallic obstacles; and the interference of the channel where the 2.4G WiFi network is located is The size of the interference signal is located about a WiFi network. 5G, the more channels the WiFi network, the greater the interference, the corresponding attenuation faster.

103. The router determines whether the signal strength of the first WiFi network and the signal strength of the second WiFi network meet a preset switching condition. If yes, go to step 104, if no, go to step 105.

The preset switching condition is different according to whether the terminal currently accesses the 2.4G WiFi network or the 5G WiFi network, or does not access the 2.4G WiFi network and the 5G WiFi network.

In a possible implementation manner, the terminal currently accesses the 2.4G WiFi network. At this time, if it is detected that the signal strength of the 5G WiFi network is greater than the first threshold, the terminal may enable the terminal to access the network from the 2.4G WiFi. The network switches to a 5G WiFi network. In an optional embodiment, the first threshold has a value of 50%. That is, when the terminal currently accesses the 2.4G WiFi network, if the signal strength of the 5G WiFi network is greater than 50%, the network access is switched from the 2.4G WiFi network to the 5G WiFi network. It can be understood that the value of the first threshold in this embodiment is 50%. In practical applications, other values may also be taken, for example, 40%, 30%, or 60%, and the like. For example, in some scenarios, even if the 5G WiFi network has only 20% signal strength, its access speed will be faster than the 2.4G WiFi network with 90% signal strength, so the value of the first threshold is even in some scenarios. Can be set to 20%.

In a possible implementation manner, the terminal currently accesses the 5G WiFi network. At this time, if the signal strength of the 5G WiFi network is detected to be less than the second threshold, and the signal strength of the 2.4G WiFi network is greater than the first threshold. The terminal can then switch the network access from the 5G WiFi network to the 2.4G WiFi network. In an optional implementation manner, the first threshold value is 50%, and the second threshold value is 20%. That is, when the terminal currently accesses the 5G WiFi network, if the signal strength of the 5G WiFi network is less than 20%, and the signal strength of the 2.4G WiFi network is greater than 50%, the network access is switched from the 5G WiFi network to 2.4. G WiFi network. The value of the first threshold is 20%. The value of the second threshold in this embodiment is only an exemplary example. In practical applications, other values, such as 15%, 30%, etc., may also be set. Wait.

In an optional implementation manner, the terminal is not currently connected to the 2.4G WiFi network and is not connected to the 5G WiFi network. If the signal strength of the 5G WiFi network is greater than the first threshold, the signal strength of the 2.4G WiFi network is not considered directly. The terminal is connected to the 5G WiFi network. For example, if the first threshold is 50%, that is, only the signal strength of the 5G WiFi network is greater than 50%, the 5G WiFi network is directly connected.

In an optional implementation manner, the terminal is not currently connected to the 2.4G WiFi network and is not connected to the 5G WiFi network, if the signal strength of the 5G WiFi network is less than the second threshold, and the signal strength of the 2.4G WiFi network is greater than the first The threshold allows the terminal to access the 2.4G WiFi network. For example, if the first threshold is 50% and the second threshold is 20%, then the 2.4G WiFi network is accessed as long as the signal strength of the 2.4G WiFi network is greater than 50% and the signal strength of the 5G WiFi network is less than 20%.

In an optional implementation manner, the specific values of the foregoing first threshold and the second threshold may be built in the terminal, that is, the user may not be set, and determined by the terminal manufacturer according to the experimental data or the big data, and then solidified in the terminal setting file. . In other embodiments, the specific values of the foregoing first threshold and the second threshold may also be set by the user according to their own network environment. In other embodiments, the terminal may also include a first threshold and a second threshold calculation algorithm, and the calculation algorithm may calculate a first threshold that matches the environment in which the user is currently located according to an environmental factor of the environment in which the user is located. The second threshold, wherein the environmental factors may include a signal attenuation rate, a transmit power of the router, a processing capability of the WiFi module of the terminal, and the like. Among them, the attenuation rate of the signal is related to the distance between the terminal and the router, the number of obstacles between the terminal and the router, and the degree of interference of the WiFi channel.

104. Enable the terminal to switch between the first WiFi network and the second WiFi network. End the process.

The router may use the method of prohibiting the terminal from accessing the first WiFi network, so that the terminal automatically accesses the second WiFi network, or the router may send a network interruption signal to the terminal, so that the terminal mistakenly believes that the first WiFi network cannot access the network. Switch to the second WiFi network.

105. Determine not to perform handover of the first WiFi network and the second WiFi network.

As can be seen from the above, in the embodiment of the present invention, the router can detect the signal strength of the first WiFi network currently accessed by the terminal, and determine the signal strength of the second WiFi network according to the signal strength of the first WiFi network, 2.4G WiFi and 5G WiFi. Signal strength, so that when the signal strength of the 2.4G first WiFi network and the signal strength of the 5G second WiFi network meet the preset switching condition, the 2.4G first WiFi network and the 5G second WiFi network are switched, thereby Taking into account the wide coverage of 2.4G WiFi and the fast speed of 5G WiFi, the user experience of using the terminal to access the network is improved. When the terminal switches from the 2.4G WiFi network to the 5G WiFi network, the network access speed of the terminal can be higher, and the network access experience of the user using the terminal is improved; when the terminal switches from the 5G WiFi network to the 2.4G WiFi network, the terminal can be made The terminal accesses the network more stably, and can also heighten the network access experience of the user using the terminal.

The terminal 202 is currently accessing a 2.4G WiFi network, but the wireless router 201 determines the terminal. The signal strength of the 5G WiFi network at the current location of 202 is greater than 50%, which causes the terminal 202 to switch from the 2.4G WiFi network to the 5G WiFi network, so that the terminal 202 can enjoy the high speed of the 5G WiFi network.

The terminal 203 is currently accessing a 5G WiFi network, but the wireless router 201 determines that the signal strength of the 5G WiFi network where the terminal 203 is currently located is less than 20%, and the signal strength of the 2.4G WiFi network is greater than 50%, so that the terminal 203 switches from a 5G WiFi network to a 2.4G WiFi network, so that it can access the Internet through a 2.4G network and enjoy high coverage of the 2.4G WiFi network.

The terminal 204 is not currently connected to the 2.4G WiFi network and is not connected to the 5G WiFi network. The router determines that the signal strength of the 5G WiFi network at the current location is greater than 50% according to the detection message sent by the terminal 204 when detecting the WiFi network, and 2.4G. The signal strength of the WiFi network is greater than 80%. Since the signal strength of 50% does not affect the network access of the terminal 204, the wireless router 201 causes the terminal 204 to access the 5G network, thereby enjoying the high speed of the 5G network.

FIG. 3 is a structural diagram of a router according to an embodiment of the present invention. As shown in FIG. 3, the router includes:

The foregoing detection may be periodic. For example, the router automatically detects the signal strength of the first WiFi network every time interval, and determines the signal strength of the second WiFi network according to the signal strength of the first WiFi network. Of course, the foregoing detection may also be triggered by an event, for example, when the router detects that the signal strength of the first WiFi network currently accessed by the terminal is lower than a certain threshold. The signal strength of the second WiFi network is determined according to the signal strength of the first WiFi network. The embodiment of the present invention does not limit the specific determination timing.

In an optional embodiment, the first threshold has a value of 50%. That is, when the terminal currently accesses the 2.4G WiFi network, if the signal strength of the 5G WiFi network is greater than 50%, the network access is switched from the 2.4G WiFi network to the 5G WiFi network. It can be understood that the value of the first threshold in this embodiment is 50%. In practical applications, other values may also be taken, for example, 40%, 30%, or 60%, and the like. For example, in some scenarios, even if the 5G WiFi network has only 20% signal strength, its access speed will be faster than the 2.4G WiFi network with 90% signal strength, so the value of the first threshold is even in some scenarios. Can be set to 20%.

In an optional implementation manner, the specific values of the foregoing first threshold and the second threshold may be built in the terminal, that is, the user may not be set, and determined by the terminal manufacturer according to the experimental data or the big data, and then solidified in the terminal setting file. . In other embodiments, the specific values of the foregoing first threshold and the second threshold are It can also be set by the user according to their own network environment.
