Background
With the development of Wireless Fidelity (WiFi) technology, most home WiFi devices, such as home gateways, routers, repeaters, etc., can support dual-band mode, i.e., 2.4G and 5G WiFi dual-band capability.
Currently, the user may Set the Service Set Identifiers (SSIDs) of 2.4G and 5G of the WiFi devices to be the same, and turn on the roaming switch. Therefore, the WiFi equipment can monitor the signal intensity between the terminals connected with the WiFi equipment in real time, and when the signal intensity reaches the threshold value set by the WiFi equipment, the frequency band is forcibly switched for the terminals.
However, the need for band switching by monitoring signal strength alone has not been met. For example: when a user watches a 4K video by using a mobile phone, the signal strength may not reach the switching threshold, and then the WiFi device does not switch the mobile phone to the 5G frequency band, and still uses the 2.4G frequency band. However, the data transmission rate of the 2.4G frequency band is low, and a user is likely to have a pause phenomenon when watching a 4K video, so that the user experience is poor.

The method for switching the WiFi frequency band provided by the embodiment of the application can be applied to a communication system comprising first electronic equipment and second electronic equipment. As shown in fig. 1, the communication system includes a first electronic device 100 and a second electronic device 200. The first electronic device 100 is a device providing WiFi signals, and may be, for example, a home gateway, a router, a repeater, a panel AP, a modem, an enterprise gateway, a mobile terminal, or the like. The second electronic device 200 is a device connected to the first electronic device 100 through WiFi, and may be a mobile phone, a computer, a Personal Digital Assistant (PDA), a laptop computer, a Set Top Box (STB), and/or other devices. The embodiment of the present application does not limit the specific forms of the first electronic device and the second electronic device.
In order to facilitate understanding of the technical solutions provided in the embodiments of the present application, a WiFi frequency band is briefly described first.
The signal frequency of the 2.4G frequency band is low, the attenuation is small when the signal propagates in the air or an obstacle, and the propagation distance is longer. However, the bandwidth of 2.4G signal is narrow, and many devices are currently using 2.4G frequency band, so the wireless environment is more crowded and the interference is larger.
The signal bandwidth of the 5G frequency band is wide, the wireless environment is clean, the interference is less, the network speed is stable, and the 5G can support higher wireless speed. However, the 5G signal has a high frequency, attenuates more when propagating through air or obstacles, and covers a relatively small distance compared to the 2.4G signal.
As can be seen from the above, 2.4G and 5G have advantages and disadvantages, and therefore, it is necessary to adopt an optimal frequency band for data transmission according to different network conditions. Then, the electronic device needs to switch different frequency bands according to different situations.
As shown in fig. 2, a schematic flow chart of a method for switching a WiFi frequency band is provided in an embodiment of the present application, where the method specifically includes:
s101, the first electronic device and the second electronic device establish connection through a first frequency band of WiFi.
In some examples of the application, the first electronic device may be a device providing a WiFi signal, the first electronic device having WiFi multi-band capability, for example: the first electronic device can provide dual-band capability for 2.4G band and 5G band WiFi. The second electronic device may be a device connected with the first electronic device through WiFi.
For example: the first electronic device is a WiFi device, and the second electronic device is a terminal. And the terminal carries out internet surfing through the WiFi signal connected with the WiFi equipment.
In other examples of the present application, the second electronic device is a device providing a WiFi signal, the second electronic device having WiFi multi-band capability, such as: the second electronic device can provide dual band capability for 2.4G band and 5G band WiFi. The first electronic device is connected with the first electronic device through WiFi.
For example: the first electronic device is a terminal, and the second electronic device is a WiFi device. And the terminal carries out internet surfing through the WiFi signal connected with the WiFi equipment.
S102, the first electronic device determines the service type of a target data packet according to the data packet transmitted between the first electronic device and the second electronic device, namely the target data packet.
Specifically, the type of the service currently used by the user is determined by analyzing the data packet transmitted between the first electronic device and the second electronic device, so as to determine whether the current data transmission of the user meets the service requirement.
For example, the determination may be made according to a Transmission Control Protocol (TCP)/User Datagram Protocol (UDP) target port number of the packet, a data communication Protocol, a packet size, and the like.
Generally speaking, the TCP/UDP target port number ranges from 1 to 65535, wherein 1 to 1023 are generally defined as common port types. These common port types usually correspond to relatively fixed traffic types, so the traffic type of the destination packet can be determined according to the TCP/UDP destination port number in the packet. Furthermore, the services of different service types have common communication protocols, so the service type corresponding to the target data packet can be determined by combining the communication protocol in the target data packet.
Then, the first electronic device may pre-store a feature table corresponding to each service type, for example: a communication protocol corresponding to each service type, a TCP/UDP target port number corresponding to each service type, the size of a data packet corresponding to each service type and the like. When the service type of the target data packet is judged, information such as a communication protocol, a TCP/UDP target port number, the size of the data packet and the like in the target data packet is read and compared with a pre-stored characteristic table corresponding to each service type. When each characteristic of the target data packet conforms to each characteristic in the pre-stored characteristic table, the target data packet can be determined to be the corresponding service type.
For example, table one is an example of a feature table corresponding to each service type, as follows:
watch 1
It should be noted that the port numbers used by most game services are clear, and the above table is only an example to give a description of several port numbers. The port numbers corresponding to other game services are not enumerated one by one.
In addition, the service type corresponding to the target data packet can be determined according to the size of the data packet. For example: typically, the packet length of game traffic is small, with the packet size being in a first interval (e.g., between 40-159 bytes), whereas the packet length of most traffic on the network is in a second interval (e.g., above 1400 bytes). Therefore, if it is detected that a certain proportion of the packets of a certain data stream are all in the first interval, and the interval time is less than 1 second, for example, it can be determined as a game service, and the TCP/UDP destination port numbers of these packets can be recorded in the feature table and labeled as a game service.
S103, the first electronic device determines a threshold corresponding to the service type according to the service type of the target data packet.
Considering that services of different service types have different requirements for data transmission, for example: in order to avoid the user from being jammed when watching high-definition, 4K, and 8K videos and affecting the user experience, the transmission rate of such video services is generally required to be high. And the game service has higher requirements on transmission rate and time delay. Therefore, in the embodiment of the present application, a data transmission requirement corresponding to the service type needs to be further determined according to the service type corresponding to the target data packet.
The threshold corresponding to the service type is used for reflecting the lowest requirement of data transmission corresponding to each service type. Wherein the threshold comprises a signal strength threshold, a data transmission rate threshold, a time delay threshold, etc. The number of the threshold values corresponding to each service type may be different, and the numerical values of the threshold values corresponding to each service type may also be different. For example, the threshold corresponding to each service type may refer to table two, as follows:
watch two
| Type of service | Internet access service | Video service | Game business | Voice service |
| Signal strength | √ | √ | √ | |
| Rate of speed | √ | √ | √ | |
| Time delay | √ | √ |
From the above, it can be seen that: for the internet access service, the problem of signal strength is generally considered, so the threshold corresponding to the internet access service is the signal strength threshold. For video traffic, signal strength and data transmission rate are generally considered, so the corresponding thresholds for video traffic include a signal strength threshold and a transmission rate threshold. For the game service, signal strength, transmission rate and delay are generally considered, so the thresholds corresponding to the game service include a signal strength threshold, a transmission rate threshold and a delay threshold. For voice services, transmission rate and delay problems are generally considered, so the corresponding threshold values of the voice services include a transmission rate threshold value and a delay threshold value.
The video service may also be specifically divided into different video modes, for example: for video services in different modes, the standard definition mode, the high definition mode, the 4K mode, the 8K mode, and the like may correspond to different thresholds, as shown in table three.
Watch III
In order to better understand the meaning of the threshold in the embodiment of the present application, as shown in table four, examples of different thresholds corresponding to different traffic types are given below. It should be noted that the numerical values herein are merely examples, and the embodiments of the present application do not limit the numerical values of the thresholds.
Watch four
And S104, the first electronic equipment determines to establish connection with the second electronic equipment through a second frequency band of WIFI according to the current data transmission parameters and the threshold corresponding to the service type of the data packet.
Wherein the first frequency band and the second frequency band are different.
The current data transmission parameters include signal strength, data transmission rate, time delay and the like. And if the current data transmission parameters meet the preset conditions, the first electronic equipment determines to establish connection with the second electronic equipment through a second frequency band of WiFi.
For example, if the service type of the target data packet is an internet service, the preset condition is that the current signal strength is less than or equal to a signal strength threshold corresponding to the internet service. If the service type of the target data packet is a video service, the preset condition is that the current signal intensity is less than or equal to a signal intensity threshold corresponding to the video service, or the current transmission rate is less than or equal to a transmission rate threshold corresponding to the video service. If the service type of the target data packet is the game service, the preset condition is that the current signal intensity is smaller than or equal to a signal intensity threshold corresponding to the game service, or the current transmission rate is smaller than or equal to a transmission rate threshold corresponding to the game service, or the current time delay is larger than or equal to a time delay threshold corresponding to the game service. If the service type of the target data packet is a voice service, the preset condition is that the current transmission rate is less than or equal to a transmission rate threshold corresponding to the voice service, or the current time delay is greater than or equal to a time delay threshold corresponding to the voice service.
For example: the user is using the first electronic device or the second electronic device to surf the internet, and the first electronic device and the second electronic device are connected through the 2.4G frequency band. When the first electronic device detects that the signal intensity of the 2.4 frequency band is less than or equal to the signal intensity threshold of 2.4G, it indicates that the signal intensity of 2.4G is very weak at this time, which may affect the internet experience of the user. Therefore, the first electronic device can be determined to be connected with the second electronic device through the 5G frequency band, so that the internet surfing experience of the user is improved.
Another example is: the user is watching a video using the first electronic device or the second electronic device, and the first electronic device and the second electronic device are connected through a 2.4G band. When the first electronic device detects that the signal intensity of the 2.4 frequency band is greater than the signal intensity threshold of 2.4G, but detects that the data transmission rate between the two devices is less than or equal to the threshold of the transmission rate corresponding to the video service, it indicates that the data transmission of the service is slow at this time, and may affect the user to watch the video. Therefore, the first electronic device can determine to connect with the second electronic device through the 5G frequency band, so as to meet the requirement of the user for watching the video service.
For another example: the user is playing a game using either the first electronic device or the second electronic device, and the first electronic device and the second electronic device are connected via the 2.4G band. When the first electronic device detects that the signal intensity of the 2.4 frequency band is greater than the signal intensity threshold of 2.4G, the data transmission rate between the two devices is also greater than the transmission rate threshold corresponding to the game service, but the time delay between the two devices is greater than or equal to the time delay threshold corresponding to the game service, which indicates that the data time delay of the service is large at this time, and the user may be influenced to play the game. Therefore, the first electronic device can determine to be connected with the second electronic device through the 5G frequency band so as to meet the game playing requirement of the user.
And then, after the first electronic device determines that the first electronic device is connected with the second electronic device through the second frequency band, the first electronic device is disconnected with the second electronic device in the first frequency band. Then, the first electronic device scans the channel of the second frequency band. When the second electronic device is scanned, authentication, association, key interaction and the like are carried out on the second electronic device, then connection is established between the second electronic device and the second electronic device in a second frequency band, and data transmission is carried out through the second frequency band.
In the embodiment of the present application, the division of the first electronic device and the second electronic device in the above embodiments may be arbitrary. That is, the first electronic device may determine the service type of the data packet, determine a corresponding threshold according to the service type, and then determine whether to switch the frequency band. Or the second electronic device determines the service type of the data packet, determines a corresponding threshold value according to the service type, and then determines whether to switch the frequency band. The embodiment of the present application does not limit this.
It should be further noted that the switching method provided in the embodiment of the present application is not only applicable to switching between 2.4G and 5G of the same electronic device, but also applicable to switching between different devices. For example, there are 2 WiFi devices in a home, and a terminal is initially connected to 2.4G of a first WiFi device, and when receiving a threshold switching operation of the first WiFi device or the terminal itself, the terminal may be connected to 5G of the first WiFi device when reconnecting, and may also be connected to 2.4G or 5G of a second WiFi device. The switching principle may refer to the above description, and will not be repeated again.
According to the method for switching the WiFi frequency band, the service type of the data packet can be determined according to the data packet transmitted between the electronic devices, and then the threshold corresponding to the service type is determined. And then determining whether the current data transmission meets a preset condition or not according to the current data transmission parameter of the data packet and the threshold. And if so, switching to the WiFi frequency band. Compared with the prior art, the electronic device only switches the WiFi frequency band according to the signal intensity, the current service requirement may not be met, and the user experience is poor. The method provided by the application can determine different threshold values according to the service types of the transmission data packets, and further determine whether to switch the frequency band according to the current data transmission condition and the threshold value condition. Therefore, the electronic equipment can adopt different service switching conditions for different service types, and the user experience is improved.
In the embodiment of the present application, the first electronic device may be divided into the functional modules or the functional units according to the above method examples, for example, each functional module or functional unit may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module may be implemented in a form of hardware, or may be implemented in a form of a software functional module or a functional unit. The division of the modules or units in the embodiment of the present application is schematic, and is only a logic function division, and there may be another division manner in actual implementation.
