[0064] The present application provides a channel switching method, device and computer device, which are described in detail below.

[0065] The channel switching method provided by the embodiments of the present application is applied to a terminal device. Please refer to FIG. 1, which is a schematic diagram of a scenario of a terminal device provided by the embodiments of the present application. The terminal device can include a first network module and a second network module. The terminal device implements a first network function through the first network module, and implements a second network function through the second network module. The first network module or the second network module in the embodiments of the present application can implement one or more network functions, which include but are not limited to one or more of a station (sta) function, an access point (ap) function, and a Peer-to-Peer (p2p) function. The first network function or the second network function belongs to one or more of the above network functions. It should be noted that the first network function implemented through the first network module and the second network function implemented through the second network module are different network functions. For example, the first network function can be a station (sta) function, and the second network function can be an access point (ap) function; for another example, the first network function can be a station (sta) function, and the second network function can be a Peer-to-Peer (p2p) function; for another example, the first network function can be an access point (ap) function, and the second network function can be a Peer-to-Peer (p2p) function, and the embodiments are not limited in this regard. The sta function is a daily used wifi scanning and connection function, the ap function represents a hotspot function, and the p2p function represents a point-to-point communication or wifi direct function.

[0066] Optionally, continuing to refer to FIG. 1, the terminal device can further include a first network management module, a second network management module, a first function operation module, a second function operation module, a first driver module, and a second driver module. The first network management module and the second network management module are used to manage the first network function and the second network function respectively.

The first driver module and the second driver module are drivers of the second network module and the first network module respectively. The first driver module and the second driver module can directly control various functions of the corresponding network module.

[0067] For example, when the first network module and the second network module are wifi chips, the first drive module and the second drive module are wifi drivers, the first network function is a sta function, and the second network function is an ap function, the first network management module is WifiManager, the second network management module is SoftApManeger, the first function operation module is wpa_supplicant, the second function operation module is hostapd, and the first drive module can directly control the ap function of the second network module, and the second drive module can directly control the sta function of the first network module.

[0068] With continuous reference to FIG. 1, the first network management module and the second network management module are arranged in a system service layer (System Service) of the terminal device, the first function operation module and the second function operation module are arranged in a hardware abstraction layer (Hardware Abstraction Layer, Hal) of the terminal device, and the terminal device further includes a first interface module and a second interface module. The first interface module and the second interface module are used for function docking between the System Service and the Hal layer, for example, the first interface module is HostapdHal, the second interface module is android.hardware.wifi.hostapd@1.2.so, and HostapdHal and android.hardware.wifi.hostapd@1.2.so are used for ap function docking between the System Service and the Hal layer.

[0069] The terminal device in the embodiment of the present application is integrated with a channel switching device, which is mainly used for acquiring a state change broadcast of a first network function, determining whether a first channel corresponding to the first network function and a second channel corresponding to a second network function exist channel conflict based on the state change broadcast, and performing channel switching on the second channel if the first channel and the second channel exist channel conflict, so as to effectively alleviate channel interference between network functions corresponding to different network modules.

[0070] The terminal device used in the embodiment of the present application can be a device including receiving and transmitting hardware, i.e., a device having receiving and transmitting hardware capable of performing bidirectional communication on a bidirectional communication link. Such a device can include a cellular or other communication device having a single-line display or a multi-line display or a cellular or other communication device without a multi-line display. The terminal device can be specifically a desktop terminal or a mobile terminal, and the terminal device can be specifically one of a mobile phone, a tablet computer, a notebook computer, and the like.

[0071] It should be noted that the scenario of the terminal device shown in FIG. 1 is only an example, and the terminal device and the scenario described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of terminal devices and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0072] First, a channel switching method, device and computer equipment are provided in the embodiments of the present application. The execution subject of the channel switching method is a channel switching device. The channel switching device is applied to a terminal device. The terminal device includes a first network module and a second network module. The terminal device realizes a first network function through the first network module. The terminal device realizes a second network function through the second network module. The channel switching method includes the following steps: acquiring a state change broadcast of the first network function; determining whether a first channel corresponding to the first network function and a second channel corresponding to the second network function exist channel conflict based on the state change broadcast; and performing channel switching on the second channel if the first channel and the second channel exist channel conflict.

[0073] As shown in FIG. 2, it is a flowchart of one embodiment of the channel switching method in the embodiments of the present application. The channel switching method can include the following steps S201-S203, which are as follows:

[0074] Step S201, acquiring a state change broadcast of the first network function.

[0075] In the embodiments, the first network function can be a station (sta) function, the first network function can also be an access point (ap) function, and the first network function can also be a Peer-to-Peer (p2p) function. The embodiments are not limited. When the first network function changes, the channel of the first network function can be switched. In order to avoid channel conflict between the first network function and the second network function, the first network management module will issue a state change broadcast when the first network function changes. For example, the first network function is a sta function. When the terminal device successfully connects to a hotspot in the environment, the terminal device is disconnected from the hotspot in the environment, or the terminal device successfully reconnects to the hotspot in the environment, it indicates that the sta function changes, and the WifiManager issues a state change broadcast.

[0076] Further, the state change broadcast refers to a data transmission or information transmission mechanism in the computer and communication fields, especially in computer networks and Android systems. This mechanism allows information to be sent from one or more sources to multiple recipients, usually used to notify or update the state of the system when a specific event occurs. In this embodiment, the state change broadcast refers to the state change information sent when the first network function changes state. The state change broadcast includes the channel identifier of the current working channel of the first network function. Based on the channel identifier of the current working channel corresponding to the first network function, it can be determined whether the working channel of the first network function has changed, and in the case of a change in the working channel of the first network function, it is determined whether there is a channel conflict between the working channel of the first network function and the working channel of the second network function.

[0077] Step S202, based on the state change broadcast, determine whether the first channel corresponding to the first network function and the second channel corresponding to the second network function exist channel conflict.

[0078] In this embodiment, the first channel refers to the current working channel of the first network function, and the second channel refers to the current working channel of the second network function. The first channel and the second channel exist channel conflict means that the first channel and the second channel are the same channel or the channel frequency of the first channel and the channel frequency of the second channel exist intersection. When the first channel and the second channel are the same channel or the channel frequency of the first channel and the channel frequency of the second channel exist intersection, since the first network function and the second network function are in different network modules, the first channel and the second channel will interfere with each other. Therefore, channel switching needs to be performed on the first channel or the second channel to avoid mutual interference between the first channel and the second channel.

[0079] Step S203, if the first channel and the second channel exist channel conflict, perform channel switching on the second channel.

[0080] In a specific embodiment, the priority of the first network function is higher than the priority of the second network function, for example, the first network function is a sta function and the second network function is an ap function. Since the channel of the first network function is determined by the environment hotspot connected by the terminal device, the priority of the sta function is higher than the priority of the ap function. After determining that the first channel and the second channel exist channel conflict in this embodiment, channel switching is performed on the second channel with lower priority, which can effectively avoid mutual interference between the first channel and the second channel.

[0081] For example, the first network function is a sta function, the second network function is an ap function, the terminal device starts the sta function and selects a channel 44 of an environment hotspot for connection, and the ap function is started by selecting a channel 149. At this time, the sta function and the ap function work in different channels and do not interfere with each other. Subsequently, the user switches the sta function to another hotspot located in the channel 149. At this time, because the sta function and the ap function work in the same channel, the channel of the sta function and the channel of the ap function interfere with each other, and the use experience of the related functions is affected. The channel switching method provided in the embodiment can effectively avoid the interference between the channel of the sta function and the channel of the ap function by switching the channel of the ap function to another channel different from the channel 149 after the channel of the sta function is switched to the channel 149.

[0082] In a specific implementation, with reference to FIG. 3, the step S201 of obtaining the state change broadcast of the first network function can include steps S301-S302, and the steps are specifically as follows.

[0083] The step S301 includes registering a broadcast listening object.

[0084] In a specific embodiment, the registration of the broadcast listening object includes creating the broadcast listening object and registering the broadcast listening object in an application. The registration of the broadcast listening object in the application includes static registration and dynamic registration. The static registration is suitable for a listening task that needs to be run when the application is started or a listener that does not need to be frequently registered and unregistered. The dynamic registration is suitable for a scenario that needs to be listened to only under specific conditions or a listener that can be conveniently unregistered when the listening condition is no longer met. The broadcast listening object of the dynamic registration is only created when the broadcast is received and is destroyed immediately after the broadcast is processed. Therefore, the dynamic registration is more lightweight and does not increase the long-term burden of the application.

[0085] The step S302 includes obtaining the state change broadcast of the first network function through the broadcast listening object.

[0086] In a specific embodiment, in combination with FIG. 1, the channel switching method is executed through a second network management module. After the second network management module registers a broadcast listening object, the state change broadcast sent by a first network management module can be obtained through the broadcast listening object. For example, the first network management module is a WifiManager, and the second network management module is a SoftapManager. After the SoftapManager registers a broadcast listening object, the state change broadcast sent by the WifiManager can be obtained through the broadcast listening object.

[0087] In a specific implementation, with reference to FIG. 4, the step of determining, in step S202, whether the first channel corresponding to the first network function and the second channel corresponding to the second network function have a channel conflict based on the state change broadcast can include steps S401-S403, which are as follows:

[0088] In step S401, a first channel identifier of the first channel is obtained from the state change broadcast.

[0089] In this embodiment, the first channel identifier is used to indicate the channel in which the first network function is currently operating. In an optional implementation, the first channel identifier can be a channel number of the first channel or a channel ID of the first channel, or other indication information used to indicate the channel in which the first network function is currently operating, which is not limited in this embodiment. For example, if the first channel is channel 149, the first channel identifier can be “149”.

[0090] In step S402, it is determined whether the first channel has changed based on the first channel identifier.

[0091] During use of the first network function, the first channel can change. For example, the first network function is a sta function, a terminal device starts the sta function and selects an environment hotspot at channel 44 for connection, and then a user switches the sta function to another hotspot at channel 149, so the first channel changes.

[0092] It is considered that the working channels of the first network function and the second network function do not have a conflict at the beginning, and the first channel and the second channel have a conflict only because of channel switching during use of the first network function. Therefore, if the first channel has not changed, the first channel and the second channel do not have a conflict at all, and only when the first channel changes, it is necessary to further determine whether the first channel and the second channel have a conflict.

[0093] In a specific embodiment, the step of determining whether the first channel has changed based on the first channel identifier specifically includes: obtaining a third channel identifier of the first channel; if the first channel identifier and the third channel identifier match, it is determined that the first channel has not changed; and if the first channel identifier and the third channel identifier do not match, it is determined that the first channel has changed.

[0094] The third channel identifier is the channel identifier of the first channel obtained from the last state change broadcast. After obtaining the third channel identifier, the third channel identifier and the first channel identifier are matched. If the first channel identifier and the third channel identifier match, it is determined that the first channel has not changed. If the first channel identifier and the third channel identifier do not match, it is determined that the first channel has changed. For example, if the first channel identifier and the third channel identifier are both 44, the first channel identifier and the third channel identifier match, and the first channel has not changed. If the first channel identifier is 44 and the third channel identifier is 149, the first channel identifier and the third channel identifier do not match, and the first channel has changed.

[0095] In step S403, if the first channel has changed, whether the first channel and the second channel have channel conflict is determined based on the first channel identifier and the second channel identifier of the second channel.

[0096] In this embodiment, the second channel identifier is used to indicate the channel currently worked by the second network function. In an optional implementation, the second channel identifier can be a channel number of the second channel or a channel ID of the second channel, and can also be other indication information used to indicate the channel currently worked by the first network function, which is not limited in this embodiment. For example, if the second channel is channel 149, the second channel identifier can be "149".

[0097] After determining whether the first channel has changed based on the first channel identifier, if the first channel has changed, whether the first channel and the second channel have channel conflict is determined based on the first channel identifier and the second channel identifier of the second channel. If the first channel has not changed, the step of obtaining the state change broadcast of the first network function is continued.

[0098] In a specific embodiment, the step of determining whether the first channel and the second channel have channel conflict based on the first channel identifier and the second channel identifier of the second channel specifically includes: matching the first channel identifier and the second channel identifier of the second channel; if the first channel identifier and the second channel identifier match, it is determined that the first channel and the second channel have channel conflict; if the first channel identifier and the second channel identifier do not match, it is determined that the first channel and the second channel do not have channel conflict.

[0099] For example, if the first channel identifier is 44 and the second channel identifier is 149, the first channel identifier and the second channel identifier do not match, and the first channel and the second channel do not have channel conflict. If the first channel identifier and the second channel identifier are both 149, the first channel identifier and the second channel identifier match, and the first channel and the second channel have channel conflict.

[0100] In a specific implementation, referring to FIG. 5, the channel switching of the second channel in step S203 can include steps S501-S503, which are specifically as follows:

[0101] Step S501, determining the fourth channel based on the first channel identifier of the first channel.

[0102] In a specific embodiment, the fourth channel is a channel different from the first channel. The step of determining the fourth channel based on the first channel identifier of the first channel specifically includes: determining a target channel identifier from the preset channel identifiers based on the first channel identifier of the first channel; the target channel identifier is a channel identifier different from the first channel identifier in the preset channel identifiers; and determining the channel corresponding to the target channel identifier as the fourth channel. For example, the commonly used wifi channels currently have 2.4G and 5G frequency bands, the commonly used channels of the 2.4G frequency band channels have channel identifiers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and the commonly used channels of the 5G frequency band channels have channel identifiers 36, 40, 44, 48, 149, 153, 157, 161, 165; if the first channel identifier is 44, the target channel identifier is determined as 149 from the channel identifiers of the commonly used 5G frequency band channels, and the channel corresponding to 149 is determined as the fourth channel.

[0103] Step S502, generating a channel switching instruction based on the fourth channel identifier of the fourth channel.

[0104] In this embodiment, the channel switching instruction is a channel switching command for switching the second channel to the fourth channel, and the second channel can be switched to the fourth channel based on the channel switching instruction, thereby avoiding the problem of channel conflict caused by the working channel of the first network function being the same as the working channel of the second network function. For example, the fourth channel identifier is 149, the second channel is channel 44, and the channel switching instruction can be "switch channel 44 to channel 149".

[0105] Step S503, channel switching of the second channel based on the channel switching instruction.

[0106] In a specific embodiment, the terminal device further includes a first driving module for controlling various functions of the second network module, and the step of channel switching of the second channel based on the channel switching instruction specifically includes: sending the channel switching instruction to the first driving module through a preset channel switching interface; and channel switching of the second channel based on the channel switching instruction through the first driving module.

[0107] The existing terminal device needs to restart the second network function to realize channel switching of the second channel. In order to realize channel switching of the second channel without restarting the second network function, referring to FIG. 1, the embodiment adds a channel switching interface in the first interface module, the second interface module and the second function operation module. The second network management module sends a channel switching instruction to the first driving module through the channel switching interface, and the first driving module performs channel switching on the second channel based on the channel switching instruction.
