Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a channel switching method provided in an embodiment of the present invention, and is applied to a terminal device, as shown in fig. 1, the method includes the following steps:
In the embodiment of the present invention, the terminal device and the routing device establish a communication connection, and the terminal device and the routing device currently perform information transmission on a first channel through a first access point, where the routing device may be a wireless router or other devices with a WIFI hotspot function, and the first access point is an access point configured for the routing device.
The target application program may be an application program with a high requirement on network communication quality, such as a game application program, a video playing application program, a video call application program, and the like, and especially, a network online game application program has a high requirement on network communication quality, and if a stuck phenomenon occurs due to network interference during a game process, game experience of a user is greatly affected.
In this embodiment, at least one application installed on the terminal device may be preset as the target application, for example, the terminal device may establish a network optimization white list, and add some types of applications to the network optimization white list by default, or a user may add some applications, which are expected to obtain better communication quality, to the network optimization white list according to a requirement of the user, so that any application in the network optimization white list may be the target application.
The detecting that the target application program is started may be detecting an operation of starting the target application program, or detecting that the target application program is in a foreground display state.
In this step, a channel switching request message may be sent to a routing device, where the channel switching request may be used to indicate the routing device, the terminal device needs to switch to another communication channel and needs to provide a second access point operating in the second channel for the routing device, where the terminal device and the routing device may define a message parsing rule in advance, so that when receiving a message sent by an opposite party, the terminal device and the routing device may respond to the message and perform corresponding operations.
The second access point may be an un-activated access point that is pre-reserved by the routing device for the terminal device, and when receiving a channel switching request message sent by the terminal device, the second access point may be activated, that is, the second access point in a dormant state is awakened, and a working channel of the second access point is configured, specifically, a second channel other than the first channel in channels that can be used by the terminal device may be used as the working channel of the second access point, for example, a second channel with better communication quality than the first channel is used as the working channel of the second access point.
After receiving the channel switching request message, the routing device may determine a second channel in response to the channel switching request message, where the second channel may be a channel with better communication quality than the first channel, such as a channel with less interference, or a channel with less number of access terminal devices.
Preferably, the communication quality of the second channel is better than the communication quality of the first channel. In this way, after receiving the channel switching request message, the routing device may determine the second channel with better communication quality than the first channel, and specifically, the routing device may determine the second channel with better communication quality by detecting the communication qualities of at least two channels, where the better communication quality may be that the transmission rate of the channel is higher, the interference is less, or the packet loss phenomenon is less, and the like.
In this embodiment of the present invention, the routing device may calculate a Signal to Interference plus Noise Ratio (SINR) of each channel by detecting the number of access points corresponding to each channel of at least two channels and the information of the packet signals transmitted and received by each access point, and further determining a second channel of the at least two channels having a higher SINR value than the first channel, wherein the at least two channels may be at least two channels in an operating frequency band supported by the routing device, for example, the routing device supports a 2.4G frequency band, the at least two channels may be any two or more of 1 channel to 13 channels, the routing device supports a 5G band, the at least two channels may be any two or more than two of the partial channels of 36 to 165 channels supported by the routing device.
The number of access points corresponding to each of the at least two channels may include the number of access points of the routing device on each channel and the number of access points of other routing devices on each channel, that is, the routing device may detect the number of access points of itself and other routing devices nearby on each channel. The information of the transmission/reception packet signal of each access point may be information such as the transmission/reception packet signal strength or signal interference condition of each access point. The calculating the SINR of each channel may be calculated according to a signal to interference plus noise ratio calculation formula according to the detected number of access points corresponding to each channel of the at least two channels and the transceiving packet signal information of each access point.
After obtaining the SINR of each channel, a second channel of the at least two channels with SINR higher than that of the first channel may be determined, preferably, the second channel may be any channel of the at least two channels with SINR higher than that of the first channel, and may also be a channel with the highest SINR among the at least two channels, so as to ensure that the terminal device can switch to a channel with better communication quality.
It should be noted that, to ensure that the terminal device can directly switch to the channel with the best current communication quality, the routing device may detect the communication quality of each channel in the frequency bands supported by the routing device, so as to determine the second channel with the best communication quality (e.g., the highest SINR).
the first response message carries information of the second access point, and a working channel of the second access point is a second channel.
After receiving the channel switching request message, the routing device may wake up the second access point in the dormant state, and configure a working channel of the second access point, for example, the second channel is used as the working channel of the second access point, so that the terminal device can complete channel switching by switching access points, reduce channel switching time, and provide switching efficiency.
After configuring the second access point, the terminal device may send a first response message carrying information of the second access point to the terminal device, and when receiving the first response message, the terminal device may switch from the first access point to the second access point according to the information of the second access point, that is, after disconnecting from the first access point, connection with the second access point is established, and after completing switching of the access points, the terminal device also switches from the first channel to the second channel.
The information of the second access point may include Basic information such as a Basic Service Set Identifier (BSSID), a Service Set Identifier (SSID), and a channel value of the second access point, where the BSSID may indicate an address of the second access point, the SSID may indicate a name of the second access point, and the channel value indicates a working channel of the second access point, that is, which channel the second channel is specifically. The terminal device may send an access request message to the second access point before disconnecting from the first access point according to the information of the second access point, and establish a connection with the second access point when receiving a message of agreeing to establish a connection sent by the second access point.
In this way, since the second access point and the routing device perform information transmission on the second channel, the connection with the second access point can be quickly established after the connection with the first access point is disconnected, and the waiting for the channel switching time of the second access point is not needed, which is equivalent to omitting the restarting step of the access point, so that the time for the terminal device to perform channel switching can be greatly reduced, the switching efficiency is improved, and the terminal device does not have an obvious pause phenomenon in the running process of the target application program.
Optionally, the step 101 includes:
under the condition that the terminal equipment performs information transmission with routing equipment through a first access point on a first channel, if the terminal equipment detects that a target application program is started, sending a first data frame to the routing equipment, wherein the first data frame comprises a first control bit, and the first control bit is used for indicating the routing equipment to provide an access point to be switched for the terminal equipment;
the step 102 comprises:
and under the condition of receiving a second data frame sent by the routing equipment, switching from the first access point to the second access point in the working state, wherein the second data frame comprises the information of the second access point.
In this embodiment, the terminal device and the routing device may agree to use a custom data frame to represent the channel switching request message and the channel switching response message. In this way, when it is detected that the target application program is started, the terminal device may send a first data frame to the routing device, where the first data frame includes a first control bit, and the first control bit is used to instruct the routing device to provide an access point to be switched for the terminal device, so that when the routing device receives the first data frame, it can know that the terminal device needs to perform channel switching.
After the routing device configures a second access point operating in the second channel, a second data frame including information of the second access point may be sent to the terminal device to indicate that the terminal device may be handed over from the first access point to the second access point.
Further, the second data frame may further include a second control bit, where the second control bit is used to indicate that the switchable access point exists in the terminal device. In this way, when the terminal device receives the second data frame, it can know that a channel with better communication quality exists and a switchable access point exists currently.
In order to distinguish the type of the message sent between the terminal device and the routing device, a message related to channel switching sent between the terminal device and the routing device may be named, for example, a gamming bit, and when the terminal device needs to send the first data frame, the value of the gamming bit may be set to 1, that is, the first control bit is a gamming bit containing a value of 1; when the routing device needs to send the second data frame, the value of the timing bit may be set to 2, that is, the second control bit is a timing bit containing a value of 2.
In this way, in this embodiment, the terminal device and the routing device may complete channel switching by sending data frames, so that the message sent between the terminal device and the routing device has the characteristics of simple data structure, high transmission speed, and the like, and is easy to parse and not prone to errors.
Optionally, after the step 101, the method further includes:
maintaining the connection with the first access point on the condition that a second response message sent by the routing equipment is received, wherein the second response message is used for indicating that the first channel is an optimal channel or no switchable access point exists; or
And under the condition that the response message sent by the routing equipment is not received within the preset time length, the connection with the first access point is kept.
In this embodiment, when the routing device detects that the communication quality of the at least two channels is worse than that of the first channel, or detects that the communication quality of the first channel in all the channels supported by the routing device is optimal, or detects that there is no available second access point (for example, the second access point has abnormality or failure), the routing device may send a second response message to the terminal device to indicate that the first channel is the optimal channel or there is no switchable access point, so that the terminal device does not need to switch channels but maintains a connection with the first access point. Specifically, a third data frame including a third control bit may be sent to the terminal device, for example, when the routing device needs to send the third data frame, the value of the timing bit may be set to 3, that is, the third control bit is a timing bit including a value of 3.
When the routing device fails to send a response message or fails to send a response message due to transient fault or interference in communication between the terminal device and the routing device, the terminal device can keep connection with the first access point, and the influence on user operation experience due to network disconnection is avoided.
In this way, when it is determined that there is no switchable channel or access point currently, or when the response message sent by the routing device is not received after timeout, the connection with the first access point can be maintained, so that a situation that a network is disconnected due to channel switching failure can be avoided.
Optionally, after the step 102, the method further includes:
disconnecting the connection with the second access point upon detecting that the target application has been closed.
In this embodiment, when it is detected that the target application is closed, for example, the target application is exited or switched to the background, the connection with the second access point may be disconnected, and the connection with the first access point may be reestablished, so that the second access point may be released, so that when the channel needs to be switched next time, the second access point is configured to operate in the better channel again, and the channel with better communication quality is switched to by switching to the second access point.
In this way, because the network environments at different times are different, the second channel on which the second access point operates is better at the current time, but the communication quality of the second channel does not always keep better with the change of the network environment, so that the connection with the second access point can be disconnected when the terminal device no longer requires higher network communication quality, and thus when the channel needs to be switched next time, the second access point can be reconfigured to operate on a better or optimal channel, and the terminal device can be ensured to be switched to a channel with a better channel when needed.
In addition, after detecting that the terminal device is disconnected from the second access point, the routing device may close the second access point, and continue to use the second access point as a reserved access point when a channel needs to be switched, so that when the channel needs to be switched next time, the second access point is configured to work in a better or more better channel again, which not only ensures that the terminal device transmits information on a channel with less interference, but also enables the terminal device to quickly realize channel switching through the switched access point.
It should be noted that the terminal device may perform channel switching when detecting the operation of starting the target application program, so that the terminal device completes channel switching when the user formally uses the target application program, thereby greatly improving the user experience of the user, and avoiding that the terminal device momentarily affects the network quality due to channel switching in the process of using the target application program (for example, in the game process) by the user.
It should be further noted that, when an Access Controller (AC) is deployed in the network communication architecture between the terminal device and the routing device, that is, both the first Access point and the second Access point are controlled by the AC, the terminal device may implement seamless roaming, that is, the switching time for switching the Access points may be controlled at millisecond level, so that packets are not substantially dropped, and no pause is experienced in service operation.
The routing device may detect the communication quality of each of at least two channels in real time or at regular intervals to determine a channel with better or optimal communication quality, and use the channel as a use channel of another access point different from the current access point, and actively send a message carrying information of the access point to the terminal device, so that the terminal device is switched to a better channel by switching to the access point.
In this embodiment of the present invention, the terminal device may be any device having a storage medium, for example: terminal devices such as computers (Computer), Mobile phones, Tablet Personal computers (Tablet Personal Computer), Laptop computers (Laptop Computer), Personal Digital Assistants (PDA), Mobile Internet Devices (MID), and Wearable devices (Wearable Device).
In the channel switching method in this embodiment, when detecting that the target application program is started, the terminal device may send a channel switching request message to the routing device, so that the routing device wakes up the second access point in the dormant state in response to the request message, and causes the second access point to operate in the second channel, and sends information of the second access point to the terminal device, and after receiving a response message that includes information of the second access point and is sent by the routing device, the terminal device may switch from the currently connected first access point to the second access point that operates in the second channel, thereby implementing fast switching from the first channel to the second channel. Therefore, the terminal equipment does not need to wait for the current access point to reconfigure the channel, so that the terminal equipment does not need to wait for a long time in the channel switching process, and further has higher switching efficiency and better communication quality.
Referring to fig. 2, fig. 2 is a flowchart of another channel switching method provided in an embodiment of the present invention, which is applied to a routing device, where the routing device performs information transmission with a terminal device in a first channel through a first access point, and the routing device further has a second access point in a dormant state, as shown in fig. 2, the method includes the following steps:
Optionally, the step 202 includes:
determining a second channel having a better communication quality than the first channel in response to the channel switching request message;
and waking up a second access point of the routing equipment, and enabling the second access point to work in the second channel.
Optionally, the determining the second channel with better communication quality than the first channel includes:
detecting the number of access points corresponding to each channel in at least two channels and the transceiving packet signal information of each access point, and calculating the signal to interference plus noise ratio (SINR) of each channel;
a second channel is determined having a higher signal to interference plus noise ratio, SINR, than the first channel.
Optionally, step 201 includes:
receiving a first data frame sent by the terminal device, wherein the first data frame comprises a first control bit, and the first control bit is used for indicating the routing device to provide an access point to be switched for the terminal device;
the step 203 comprises:
and sending a second data frame to the terminal equipment, wherein the second data frame comprises information of a second access point of the routing equipment.
Optionally, the second data frame further includes a second control bit, where the second control bit is used to indicate that a switchable access point exists in the terminal device.
Optionally, after step 201, the method further includes:
and under the condition that the communication quality of the first channel is better than that of other channels which can be used by the routing equipment, sending a second response message to the terminal equipment, wherein the second response message is used for indicating that the first channel is an optimal channel.
Optionally, after step 203, the method further includes:
and closing the second access point under the condition that the second access point is detected to be disconnected with the terminal equipment.
It should be noted that, in this embodiment, the routing device is used as a routing device corresponding to the embodiment shown in fig. 1, and for avoiding repetition, detailed descriptions thereof may be referred to in the embodiment shown in fig. 1.
In the channel switching method in this embodiment, after receiving a channel switching request message sent by a terminal device, a routing device may wake up a second access point in response to the request message, configure a working channel of the second access point as a second channel, and send information of the second access point to the terminal device, so that the terminal device switches from a currently connected first access point to a second access point working in the second channel after receiving the information of the second access point, thereby implementing fast switching from the first channel to the second channel. Therefore, the terminal equipment does not need to wait for the current access point to reconfigure the working channel, so that the terminal equipment does not need to wait for a long time in the channel switching process, and the terminal equipment is ensured to have higher switching efficiency and better communication quality.
