Step 101 carries out information transmission in the first channel by the first access point and routing device in the terminal device In the case where, if detecting, destination application is had been turned on, channel switch request message is sent to the routing device, In, the routing device also has the second access point in a dormant state.

In the embodiment of the present invention, the terminal device and routing device foundation have communication connection, and the terminal device It is currently that information transmission is carried out by the first access point on the first channel with the routing device, wherein the routing device It can be wireless router or other have the equipment of WIFI hot spot function, first access point is routing device configuration Access point.

Above-mentioned destination application can be the application program more demanding to network communication quality, such as game class application journey Sequence, video playback class application program, video calling class application program etc., the especially online class game application of network, to net Network QoS requirement is higher, if occurring the phenomenon that Caton because of network interferences in game process, will extremely influence user Game experiencing.

In the present embodiment, can preset at least one application program installed on the terminal device is the target Application program for example, terminal device can establish a network optimization white list, and is defaulted and adds certain form of application program Certain expectations can be obtained the application of preferred communication quality according to self-demand by adding to network optimization white list or user Program is added to network optimization white list, in this way, any application program in the network optimization white list may each be described Destination application.

It is above-mentioned to detect that destination application has been turned on, it can be the operation for detecting and starting the destination application, Or detect that the destination application is in foreground and shows state.

In the case where detecting that destination application has been turned on, it is believed that terminal device needs to carry out at this time channel and cuts More preferably communication channel is changed or needs to switch to, to meet requirement of the destination application to network communication quality, therefore, In the step, channel switch request message can be sent to routing device, the channel switch request, which can be, is used to indicate institute Routing device is stated, the terminal device needs to switch to other communication channels, and the routing device is needed to be provided work In the second access point of the second channel, wherein the terminal device and the routing device can pre-define good news Resolution rules are able to respond so that the terminal device and the routing device are when receiving the message of other side's transmission in this Message, and execute corresponding operation.

Wherein, second access point can be the routing device in advance and be reserved inactive of the terminal device Access point can start second access point when receiving the channel switch request message that the terminal device is sent, Second access point in a dormant state is waken up, and configures the working channel of second access point, specifically can be Second channel in the channel that the terminal device can be used in addition to first channel is as second access point Working channel, such as the second channel using communication quality better than first channel is as the working channel of second access point.

The routing device can switch in response to the channel and ask after receiving the channel switch request message Message is sought, determines second channel, wherein the second channel can be the channel that communication quality is better than first channel, such as Less channel is interfered, the channel of the terminal device negligible amounts of access is also possible to.

Preferably, the communication quality of the second channel is better than the communication quality of first channel.In this way, the routing Equipment can determine second letter of the communication quality better than first channel after receiving the channel switch request message Road, specifically, the routing device can be by the communication qualities of at least two channels of detection, to determine communication quality preferably Second channel, wherein the more excellent transmission rate that can be the channel of the communication quality is higher, interfere less or packet loss phenomenon compared with It is few etc..

In the embodiment of the present invention, the routing device can connect by the way that each channel is corresponding at least two channels of detection The send and receive packets signal message of access point quantity and each access point, to calculate the signal and interference plus noise of each channel Than (Signal to Interference plus Noise Ratio, abbreviation SINR), and then determine at least two channel Middle SINR value is higher than the second channel of first channel, wherein at least two channel can be the routing device institute At least two channels in the working frequency range of support, for example, the routing device supports 2.4G frequency range, then described at least two believe Road can be any two or more than two channel, the routing device of 1 channel into 13 channels and support 5G frequency range, then described At least two channels can be any two of 36 channels that the routing device is supported in the local channel into 165 channels Or more than two channels.

The corresponding number of access point of each channel at least two channel may include routing device described each Number of access point and number of access point of other routing devices on each channel on channel, i.e., the described routing device can To detect the number of access point of itself and other neighbouring routing devices on each channel.The receipts of each access point Give out a contract for a project signal message, can be the information such as send and receive packets signal strength or the signal interference situation of each access point.It is described to calculate The SINR of each channel can be according to the corresponding access point of channel each at least two channel detected The send and receive packets signal message of quantity and each access point, is calculated according to Signal to Interference plus Noise Ratio calculation formula.

After the SINR for obtaining each channel, it can determine at least two channel that SINR is higher than described the The second channel of one channel, it is preferred that the second channel can be higher than first letter by SINR at least two channel Any channel in road can also be preferably the highest channel of SINR at least two channel, to ensure the terminal device It allows hand over to communication quality more preferably channel.

It should be noted that ensure that the terminal device can be directly switch into the channel of present communications optimal quality, institute The communication quality of each channel in the frequency range that it is supported can be detected by stating routing device, to determine communication quality most The second channel of excellent (such as SINR highest).

Step 102, in the case where receiving the first response message that the routing device is sent, from first access Point switches in running order second access point；

Wherein, first response message carries the information of second access point, the work of second access point Channel is second channel.

The routing device can wake up in a dormant state after receiving the channel switch request message Two access points, and the working channel of second access point is configured, such as using second channel as second access point Working channel reduce channel so that the terminal device can complete the switching of channel by way of switching access point Switching time provides switching efficiency.

After being configured to second access point, it can be sent to the terminal device and carry second access First response message of the information of point, the terminal device, can be according in the case where receiving first response message According to the information of second access point, second access point is switched to from first access point, that is, is disconnected and described first Established after the connection of access point with the connection of second access point, after the completion of access point switching, the terminal device also from First channel has switched to the second channel.

Wherein, the information of second access point may include the basic service set identification (Basic of second access point Service Set Identifier, abbreviation BSSID), service set (Service Set Identifier, abbreviation SSID) The address of second access point can be indicated with essential informations, the BSSID such as channel values, and the SSID can indicate described The title of second access point, the channel value then indicate that the working channel of second access point, i.e., the described second channel are specific For which channel.The terminal device can disconnect and first access point according to the information of second access point Second access point described in the forward direction of connection sends access request message, establishes receiving the agreement that second access point is sent In the case where the message of connection, connection is established with second access point.

In this way, since second access point has been transmitted with the routing device in the enterprising row information of the second channel, To can rapidly establish the connection with second access point after disconnecting the connection with first access point, without The channel switch time of second access point is waited, that is, eliminating the reboot step of access point, and then can greatly be subtracted Few terminal device carries out the time of channel switching, improves switching efficiency, the terminal device is in the destination application Operational process in apparent Caton phenomenon will not occur.

Optionally, the step 101 includes:
