[0036] Figure 2 For a hardware structure diagram of the terminal device provided in the embodiment of the present application, please refer to Figure 2 The terminal device may be the first terminal device or the second terminal device, and is not specifically limited here. The terminal device includes a processor 210, a memory 220, a transceiver 230, a display unit 240, an input unit 250, a sensor 260 and other components.

[0037] The processor 210 is the control center of the terminal device, and uses various interfaces and lines to connect various parts of the entire terminal device. By running or executing software programs and / or modules stored in the memory 220, and calling data stored in the memory 220, the processor 210 performs various functions of the terminal device and processes data, thereby monitoring the terminal device as a whole. Optionally, the processor 210 may include one or more processing units; optionally, the processor 210 may integrate an application processor, which mainly processes operating devices, user interfaces, and application programs, etc. Of course, other processors may also be included, which are not listed here one by one.

[0038] The memory 220 can be used to store software programs and modules. The processor 210 executes various functional applications and data processing of the terminal device by running the software programs and modules stored in the memory 220. The memory 220 mainly includes a program storage area and a data storage area, wherein the program storage area can store operating devices, at least one application required for a function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the terminal device (such as audio data, a phone book, etc.), etc. In addition, the memory 220 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0039] The transceiver 230 can provide wireless communication solutions applied to terminal devices, including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc. The transceiver 230 can be one or more devices integrating at least one communication processing module, for example, integrating an antenna and a baseband processor into the transceiver 230, or integrating an antenna and a modem processor into the transceiver 230, etc., which are not limited here.

[0040] The display unit 240 may be used to display information input by the user or information provided to the user and various menus of the terminal device. The display unit 240 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc., which is not limited here.

[0041] The input unit 250 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the terminal device. Among them, the input unit 250 can collect the user's operations on or near it, and drive the corresponding connection device according to a pre-set program. In addition, the input unit 250 may include a touch panel, which can be implemented in various types such as resistive, capacitive, infrared and surface acoustic wave. In addition to the touch panel, the input unit 250 may also include other input devices.

[0042] The terminal device may also include at least one sensor 260, such as a gyroscope sensor, a motion sensor, and other sensors. The motion sensor may include an acceleration sensor for detecting the magnitude of acceleration in all directions, and the magnitude and direction of gravity when stationary, which may be used for applications that identify the posture of the terminal device, such as horizontal and vertical screen switching, related games, magnetometer posture calibration, etc. As for other sensors that may be configured in the terminal device, such as a pressure gauge, a barometer, a hygrometer, a thermometer, an infrared sensor, a fingerprint sensor, etc., they will not be described in detail here.

[0043] It is to be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the terminal device. In other embodiments of the present application, the terminal device may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0044] The above explains the hardware structure of the first terminal device and the second terminal device. The following explains the software architecture of the first terminal device and the second terminal device.

[0045] Figure 3 This is a schematic diagram of the software architecture of the terminal device provided in the embodiment of the present application. Please refer to Figure 3 The software architecture includes: a business layer 310, a framework layer 320 and an implementation layer 330.

[0046] Among them, the business layer 310 is used to realize business docking. For example, a user can actively initiate a connection with other terminal devices through the corresponding application, or receive a connection with other devices. Moreover, during the data transmission process, the user can realize the selection of the data transmission channel through the business layer. In addition, the business layer 310 provides business data, and during the data transmission process, the business data can be transmitted, for example, sending business data or receiving business data.

[0047] The framework layer 320 is used for transmission management, and the framework layer 320 may include the following modules: an interface providing module, a channel selecting module, an interface defining module, and a transmission management module.

[0048] The interface providing module (ITransportInterface) may be a module for providing an interface to the business layer, for example, it may provide a broadcast interface, a device discovery interface, a connection establishment interface, an active disconnection interface, etc. of the business layer.

[0049] The channel selection module (TransportManager) can provide the service quality of various channels such as data transmission channels, broadcast transmission channels, etc., and provides the ability to select channels.

[0050] The interface definition module (ITransportOperator) may be a module for standardizing the definition of various interface functions, and may also register different transmission channels. For example, when a new transmission channel needs to be added, the definition functions related to the channel may be recorded in the module.

[0051] The transmission management module (DefaultTransportImpl) can use a fixed template to record the process adopted in the transmission process, for example: recording a specific transmission path, recording the order of each transmission step, etc., without specific restrictions here. This module can realize the message relationship in the connection process, and this module can be compatible with different types of data transmission, for example: it can be compatible with Bluetooth transmission and wireless network transmission.

[0052] In addition, the transmission management module also includes a timeout disconnection submodule (DisconnectManager), through which management after the transmission channel is established can be provided. For example, after the connection is established for more than a preset time, a timeout disconnection strategy can be triggered to disconnect the connection.

[0053] The implementation layer 330 may include a plurality of different types of transmission channels, as well as multiple transmission channels of the same type, for implementing processes such as data transmission through the transmission channels.

[0054] Among them, a plurality of different types of transmission channels refer to transmission channels with different communication methods, for example: channel 1 is a Bluetooth channel, channel 2 is a WIFI channel, then channel 1 and channel 2 can be transmission channels of different types; multiple channels of the same type refer to multiple transmission channels with the same communication method, for example: channel 3 is a Bluetooth channel, channel 4 is also a Bluetooth channel, then channel 3 and channel 4 can be multiple channels of the same type.

[0055] The above explains the hardware structure and software architecture of the first terminal device and the second terminal device. The following explains the data transmission method provided in the embodiment of the present application.

[0056] It should be noted that for two different terminal devices, for example: a first terminal device and a second terminal device, during the process of communication between devices, the communication method adopted is usually to exchange data through a fixed transmission channel. For example: when sharing information A, the information transmission method adopted is Bluetooth transmission method, which is completed based on the software framework provided in the relevant technology.

[0057] However, in actual communication, other transmission channels may be required for data exchange between devices, for example, wireless communication may be required, or, when a device has multiple Bluetooth channels, another Bluetooth channel may be selected to implement Bluetooth transmission.

[0058] In the related art, a fixed transmission channel cannot be actively switched, and the user cannot actively select the data transmission channel. This leads to large limitations on the transmission channel used and the inability to achieve autonomous switching. In order to solve this technical problem existing in the related art, a data transmission method is provided in an embodiment of the present application. The implementation process of the data transmission method is explained below.

[0059] Figure 4 This is a flow chart of the data transmission method provided in the embodiment of the present application, please refer to Figure 4 , the method comprising:

[0060] S410: Acquire data to be transmitted and a data transmission identifier of the data to be transmitted.

[0061] The data transmission identifier of the data to be transmitted is used to indicate the target transmission channel used by the data to be transmitted.

[0062] It should be noted that the execution subject of the method may be the above-mentioned first terminal device.

[0063] Optionally, the data to be transmitted may be service data generated by a service layer of the first terminal device. For example, for a screen projection service, the video data, audio data, etc. transmitted during the screen projection process may be the data to be transmitted.

[0064] In one embodiment, the data to be transmitted may be data that needs to be transmitted to a second terminal device. For example, for a screen projection service, the first terminal device is a mobile phone and the second terminal device is a projector. If the projector needs to be used to play the corresponding projection content, then the video data and audio data corresponding to these projection contents are the above-mentioned data to be transmitted.

[0065] Optionally, the second terminal device can be determined based on the content of the data to be transmitted, or can be determined based on the user's choice, for example: determining a device from multiple terminal devices as the second terminal device based on the content of the data to be transmitted; or, based on the user's choice, determining a device from multiple terminal devices as the second terminal device.

[0066] For example: the service layer of the first terminal device generates certain service data. After determining the size and type of the service data, or determining the application that generates the service data, the target device to which the service data needs to be sent can be determined according to the size and type of the service data or the application that generates the service data. Service data of different sizes, different types, and service data generated by different applications can be sent to different target devices respectively. For example, the first type of service data can be sent to device A, and the second type of service data can be sent to device B. Based on the above method, multiple different data to be transmitted can be obtained.

[0067] It should be noted that, in addition to carrying the data to be transmitted, it can also carry a data transmission identifier of the data to be transmitted, which can indicate the target transmission channel used by the data to be transmitted. For example, multiple transmission channels that can be used in the first terminal device can be numbered, and then in the process of generating the data to be transmitted, an identifier is generated to specify the number of the transmission channel to be used, so that the data transmission identifier of the data to be transmitted can be obtained.

[0068] The data transmission identifier may be an identifier actively selected or input by the user through the service layer.

[0069] For example, the business layer can obtain the identifiers of various channels that can be used in the implementation layer through the corresponding interface, and then provide corresponding options. Based on the user's operation on the business layer, the corresponding option can be selected to generate the corresponding identifier.

[0070] For example: if the first terminal device has two Bluetooth channels, the identifier of Bluetooth channel 1 is: BT1, and the identifier of Bluetooth channel 2 is: BT2. After the business layer obtains these identifiers through the corresponding interface, BT1 and BT2 can be displayed in the display interface of the first terminal device. Then, based on the user's selection of display content, for example, if BT2 is selected, the identifier BT2 corresponding to Bluetooth channel 2 can be generated, so that it can be determined that the transmission channel to be used for the data to be transmitted during the transmission process is Bluetooth channel 2, that is, the target transmission channel is Bluetooth channel 2.

[0071] S420: When a target transmission channel is established with the second terminal device, the data to be transmitted is sent to the second terminal device through the target transmission channel.

[0072] Optionally, the first terminal device can determine the communication connection relationship between itself and other terminal devices. When it is determined to establish a target transmission channel with the second terminal device, the acquired data to be transmitted can be sent to the second terminal device. For example, the data to be transmitted can be sent to the second terminal device through the target transmission channel.

[0073] It should be noted that if the first terminal device has multiple Bluetooth channels, such as Bluetooth channel 1 and Bluetooth channel 2, the target transmission channel to be used can be determined according to the data transmission identifier of the data to be transmitted, and then the target transmission channel can be used to send the data to be transmitted to the second terminal device.

[0074] In the data transmission method provided in the embodiment of the present application, the data to be transmitted and the data transmission identifier of the data to be transmitted can be obtained, wherein the data transmission identifier of the data to be transmitted is used to indicate the target transmission channel used by the data to be transmitted; in the case of establishing a target transmission channel with the second terminal device, the data to be transmitted is sent to the second terminal device through the target transmission channel. Among them, the specified target transmission channel can be established with the second terminal device through the data transmission identifier, so that the data transmission between the first terminal device and the second terminal device can be realized through the target transmission channel, that is, the selection of the transmission channel in the data transmission process between devices can be realized, so that a more suitable data transmission channel can be used for data interaction between devices.

[0075] In order to more clearly demonstrate the process of data interaction between the first terminal device and the second terminal device, the data transmission method provided in the embodiment of the present application is explained below through a feasible interaction method.

[0076] Figure 5 For a schematic diagram of the interaction between the first terminal device and the second terminal device provided in the embodiment of the present application, please refer to Figure 5 , the method comprising:

[0077] S510: The first terminal device receives first broadcast data sent by the second terminal device.

[0078] S520: The first terminal device obtains the data to be transmitted and a data transmission identifier of the data to be transmitted.

[0079] S530: When the first terminal device and the second terminal device establish a target transmission channel, the first terminal device sends the data to be transmitted to the second terminal device through the target transmission channel.

[0080] In one embodiment, before acquiring the data to be transmitted and the data transmission identifier of the data to be transmitted, the method further includes: receiving first broadcast data sent by the second terminal device.

[0081] The first broadcast data includes at least one first data transmission channel identifier, and the first data transmission channel identifier is used to indicate the type of transmission channel supported by the second terminal device for transmitting data.

[0082] It should be noted that the second terminal device can use the method of sending broadcasts to find other devices with which data interaction can be performed. After the first terminal device receives the broadcast sent by the second terminal device, a data transmission channel can be established.

[0083] Optionally, the content broadcast by the second terminal device may be first broadcast data, wherein the first broadcast data may include a device identifier of the second terminal device and a first data transmission channel identifier, wherein the first data transmission channel identifier is used to indicate the type of transmission channel supported by the second terminal device for transmitting data, for example: if the second terminal device supports Bluetooth transmission and WIFI transmission, the first data transmission channel identifier may represent the identification information corresponding to Bluetooth and WIFI.

[0084] After acquiring the first broadcast data, the first terminal device can determine the type of data transmission channel that the second terminal device can support through the framework layer, and then in the process of generating the data transmission identifier of the data to be transmitted, it can generate an identifier corresponding to the transmission channel of this type.

[0085] It should be noted that the second terminal device and the first terminal device have at least one identical data transmission channel identifier.

[0086] In the data transmission method provided in the embodiment of the present application, the first broadcast data sent by the second terminal device can be received before obtaining the data to be transmitted and the data transmission identifier of the data to be transmitted. The first broadcast data includes at least one first data transmission channel identifier, and the first data transmission channel identifier is used to indicate the type of transmission channel supported by the second terminal device for transmitting data. The first broadcast data can more quickly and accurately determine the type of transmission channel supported by the second terminal device for transmitting data, thereby more quickly determining that the first terminal device can select multiple data transmission channels.

[0087] In one embodiment, the target transmission channel is one of at least one data transmission channel corresponding to at least one identical data transmission channel identifier.

[0088] For example, if the second terminal device has a Bluetooth channel and a WIFI channel, and the first terminal device also has a Bluetooth channel and a WIFI channel, it can be determined that these two channels are the data transmission channels corresponding to the same data transmission channel identifier, and either the Bluetooth channel or the WIFI channel can be used as the data transmission channel.

[0089] In the case that the first terminal device has multiple Bluetooth channels and multiple WIFI channels, all of these channels can be used as data transmission channels, and one of them can be selected from these channels as the target transmission channel.

[0090] It should be noted that, in the process of selecting the target transmission channel, multiple data transmission channels can be first determined according to the transmission channel types supported by both the first terminal device and the second terminal device, and then one is determined from these data transmission channels as the target transmission channel. In the process of selecting the target transmission channel, the following method can be used for selection:

[0091] In one embodiment, the method further includes: in response to a selection operation for a transmission channel, determining a target transmission channel from at least one data transmission channel corresponding to at least one same data transmission channel identifier.

[0092] It should be noted that the framework layer of the first terminal device can determine at least one data transmission channel based on the first broadcast data, and transmit the options corresponding to multiple data transmission channels to the business layer. The user can select the data transmission channel by interacting with the display interface.

[0093] For example: the data transmission channels include: Bluetooth channel 1, Bluetooth channel 2, WIFI channel 1, and WIFI channel 2. The business layer can display these channels in the display interface, and then respond to the user's selection operation, that is, the selection operation for the transmission channel, select one of the above four channels as the target transmission channel, and accordingly, generate a data transmission identifier corresponding to the target transmission channel.

[0094] It should be noted that the above process is a process in which the second terminal device actively initiates the broadcast. In the actual implementation process, in addition to the second terminal device initiating the broadcast, the first terminal device can also initiate the broadcast.

[0095] Figure 6 Another interaction diagram between the first terminal device and the second terminal device provided in the embodiment of the present application is shown in FIG. Figure 6 , the method comprising:

[0096] S610: The first terminal device broadcasts second broadcast data.

[0097] S620: The first terminal device receives a channel establishment request sent by the second terminal device.

[0098] S630: The first terminal device obtains the data to be transmitted and a data transmission identifier of the data to be transmitted.

[0099] S640: When the first terminal device establishes a target transmission channel with the second terminal device, the first terminal device sends the data to be transmitted to the second terminal device through the target transmission channel.

[0100] In one embodiment, before obtaining the data to be transmitted and the data transmission identifier of the data to be transmitted, the method also includes: broadcasting second broadcast data, the second broadcast data including: at least one second data transmission channel identifier of the first terminal device, the second data channel identifier is used to indicate the type of transmission channel supported by the first terminal device for transmitting data; receiving a channel establishment request sent by the second terminal device, and establishing a target transmission channel according to the channel establishment request.

[0101] The second broadcast data includes at least one second data transmission channel identifier, and the second data transmission channel identifier is used to indicate the type of transmission channel supported by the first terminal device for transmitting data.

[0102] It should be noted that the first terminal device can use the broadcast method to find other devices with which data can be interacted. After the second terminal device receives the broadcast sent by the first terminal device, the first terminal device can receive the channel establishment request sent by the second terminal device.

[0103] Optionally, the content broadcast by the first terminal device may be second broadcast data, wherein the second broadcast data may include a device identifier of the first terminal device and a second data transmission channel identifier, wherein the second data transmission channel identifier is used to indicate the type of transmission channel supported by the first terminal device for transmitting data, for example: if the first terminal device supports Bluetooth transmission and WIFI transmission, the second data transmission channel identifier may represent the identification information corresponding to Bluetooth and WIFI.

[0104] Optionally, the first terminal device can send the second broadcast data by broadcasting. After receiving the second broadcast data, the second terminal device can establish a channel connection with the first terminal device. For example, a channel establishment request can be sent first, and after the first terminal device agrees, a data transmission channel between the first terminal device and the second terminal device can be established, thereby realizing data transmission.

[0105] In the data transmission method provided in the embodiment of the present application, before obtaining the data to be transmitted and the data transmission identifier of the data to be transmitted, the first terminal device can broadcast the second broadcast data, and then the first terminal device receives the channel establishment request sent by the second terminal device. The second broadcast data can more quickly and accurately determine the second terminal device that can perform data transmission with the first terminal device, thereby realizing data transmission more quickly.

[0106] It should be noted that, during the broadcasting process, the first terminal device may also use the corresponding broadcast channel to complete the broadcast transmission.

[0107] Figure 7 Please refer to the flowchart of determining the target broadcast channel provided in the embodiment of the present application. Figure 7 , before broadcasting the second broadcast data, the method further includes:

[0108] S710: Determine a target broadcast channel according to at least one broadcast channel corresponding to at least one broadcast channel identifier.

[0109] Among them, at least one broadcast channel identifier is used to indicate the type of broadcast channel supported by other terminal devices discovered by the first terminal device.

[0110] For example, if the first terminal device has two broadcast channels, namely a Bluetooth channel and a WIFI channel, it can be determined that these two channels are broadcast channels, and one of the broadcast channels can be selected from the multiple broadcast channels as the target broadcast channel.

[0111] It should be noted that the broadcast channel identifier can be used to indicate one of the transmission channels, and the first terminal device can broadcast based on the transmission channel.

[0112] The broadcast channel and the data transmission channel can be the same channel or different channels, and there is no specific limitation here. For example, if Bluetooth channel 1 is used for broadcasting and Bluetooth channel 2 is used for data transmission, then in this scenario, Bluetooth channel 1 is the broadcast channel and Bluetooth channel 2 is the data transmission channel; if Bluetooth channel 1 is used for broadcasting and data transmission in turn, then in this scenario, Bluetooth channel 1 is both the broadcast channel and the data transmission channel.

[0113] Optionally, determining the target broadcast channel according to at least one broadcast channel identifier includes: determining the target broadcast channel from at least one broadcast channel in response to a selection operation on the broadcast channel.

[0114] It should be noted that the framework layer of the first terminal device can determine at least one broadcast channel based on the broadcast capability of the first terminal device itself, and transmit the options corresponding to multiple broadcast channels to the business layer. The user can select the broadcast channel by interacting with the display interface.

[0115] For example: the broadcast channels include: Bluetooth channel 1, Bluetooth channel 2, WIFI channel 1, and WIFI channel 2. The business layer can display these channels in the display interface, and then respond to the user's selection operation, that is, the selection operation for the broadcast channel, and select one of the above four channels as the target broadcast channel.

[0116] Accordingly, broadcasting the second broadcast data includes:

[0117] S720: Broadcast the second broadcast data through the target broadcast channel.

[0118] It should be noted that after determining the target broadcast channel from the multiple broadcast channels in the above manner, the second broadcast data can be broadcast through the target broadcast channel, so that the second terminal device can receive the second broadcast data.

[0119] In the data transmission method provided in the embodiment of the present application, the target broadcast channel can be determined according to at least one broadcast channel corresponding to at least one broadcast channel identifier; and the second broadcast data can be broadcast through the target broadcast channel. Among them, the broadcast channel identifier can more quickly determine multiple broadcast channels that can be selected, and then the target broadcast channel can be determined more quickly.

[0120] In one embodiment, the target transmission channel is a factory-preset data transmission channel of the terminal device, or a data transmission channel configured by the user.

[0121] It should be noted that the target transmission channel used by the first terminal device or the second terminal device may be a default data transmission channel or an additionally added data transmission channel, wherein the default data transmission channel may be a factory-preset data transmission channel and the additionally added data transmission channel may be a user-configured data transmission channel.

[0122] For example: the first terminal device is configured with one Bluetooth channel and one WIFI channel when leaving the factory, and both channels are factory preset data transmission channels; if the user actively adds another Bluetooth channel, this Bluetooth channel can be a data transmission channel configured by the user.

[0123] In the actual implementation process, both types of data transmission channels mentioned above can be used as target transmission channels.

[0124] The specific implementation process of establishing a data transmission channel provided in the embodiment of the present application is explained below.

[0125] Figure 8 Please refer to the flowchart of establishing a data transmission channel provided in the embodiment of the present application. Figure 8 , the method further comprises:

[0126] S810: Obtain channel configuration information.

[0127] S820: Establish a data transmission channel configured by the user according to the channel configuration information.

[0128] The channel configuration information includes at least one of the type of the channel, the transmission protocol used by the channel, and the interface information of the channel.

[0129] It should be noted that the channel configuration information may be information input by the user. For example, the configuration information may be input into the framework layer of the first terminal device, and the interface definition module may store the type of channel, the transmission protocol used by the channel, etc., and the interface provision module may store the interface information of the channel, etc., thereby realizing access to a new channel.

[0130] It should be noted that after obtaining the channel configuration information, a new data transmission channel can be established, for example: a new transmission channel is established in the implementation layer, and the framework layer manages the transmission channel in the implementation layer, thereby completing the establishment of the user-configured data transmission channel.

[0131] In the data transmission method provided in the embodiment of the present application, channel configuration information can be obtained; and a user-configured data transmission channel can be established according to the channel configuration information. The establishment of the user-configured data transmission channel can be realized through the software architecture of the first terminal device, so that a new data transmission channel can be additionally established for the first terminal device.

[0132] Optionally, when establishing a target transmission channel with the second terminal device, the method further includes: disconnecting the target transmission channel when no data transmission in the target transmission channel exceeds a target preset time length.

[0133] It should be noted that this process can be implemented by the timeout disconnection submodule in the transmission management module in the framework layer of the first terminal device, which is used to manage the connection disconnection strategy and can implement the reporting and disconnection process of the encapsulated connection.

[0134] For example, the default implementation can be timeout disconnection. The optional strategy is that the idle time of each channel cannot exceed 60s. The timing start time can be refreshed after each data transmission is completed, and the timed-out channel can be removed after the timer times out.

[0135] For example, if transmission channel 1 does not transmit any data within 60 seconds, it can be determined that transmission channel 1 is a timed-out transmission channel and the connection of the transmission channel can be disconnected.

[0136] The data transmission method provided in the embodiment of the present application encapsulates the broadcast, discovery, connection establishment, and disconnection processes into a unified transmission management framework, and isolates the implementation of the specific transmission process through the interface provided to the outside, so as to achieve the purpose of decoupling the upper-layer business from the specific connection process. At the same time, the access method implemented by the underlying specific transmission technology is opened, and the user can independently access the transmission channel and can also independently select the transmission channel used for broadcast and data transmission.

[0137] Fig. 9 For the overall relationship diagram of the transmission process provided in the embodiment of this application, please refer to Fig. 9 The first terminal device and the second terminal device may both have a business layer, a framework layer and an implementation layer. When the two terminal devices establish a channel connection, they may select a corresponding transmission channel at the implementation layer to realize the connection.

[0138] For example: Fig. 9 In the process shown in , the first terminal device and the second terminal device may both have two Bluetooth channels and one WIFI channel. During the process of establishing a data channel, the two may select corresponding channels to establish a connection.

[0139] pass Fig. 9 According to the process shown, the data transmission method can be divided into a device discovery process and a data transmission process.

[0140] Among them, during the device discovery process, the business layer transmits the selected scanning and discovery channels and the required transmission channel types to be carried in the broadcast data through the broadcast and scanning interfaces provided by the framework layer. For example, device 1 specifies broadcasting and discovery through Bluetooth channel 1, and carries a tag that the business data supports transmission through Bluetooth channel 1, Bluetooth channel 2, and WIFI channel; device 2 specifies broadcasting and discovery through Bluetooth channel 1, and carries a tag that the business data supports transmission through Bluetooth channel 1 and WIFI channel. The framework layer encapsulates the information of the current device and the transmission channel type required by the business, and passes the scanned data to the corresponding selected transmission channel. Depending on the implementation of the specific transmission channel, the broadcast data is broadcasted and the broadcast data of the other end is scanned and obtained, and the received broadcast data is passed to the transmission management framework layer for parsing and encapsulation as the scanned device, and further passed to the business layer.

[0141] In the data transmission process, the business layer passes the selected transmission channel and the data to be transmitted through the interface provided by the framework layer. The framework layer finds the specific transmission channel implementation according to the channel provided by the calling service. If the current transmission channel has established a connection, the business data is directly transmitted, otherwise the channel establishment process is executed first. After the channel is established, the business data is transmitted to the peer device depending on the implementation of the specific transmission channel.

[0142] It should be understood that, although the steps in the above-mentioned flowcharts are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the above-mentioned flowcharts may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the sub-steps or stages of other steps.
