    Abstract: A method is applied to an electronic device. The electronic device includes a basic application layer, a basic service layer, and an access layer, the access layer includes a first access layer and a second access layer, and the first access layer and the second access layer support different data transmission capabilities. The method includes: The basic application layer requests the basic service layer to establish a service channel for a communication service of an application. The basic service layer establishes a transmission channel group for the communication service if the communication service supports multilink transmission. The transmission channel group includes a first service channel and/or a second service channel, the first service channel corresponds to the first access layer, and the second service channel corresponds to the second access layer. The electronic device transmits service data of the communication service based on the transmission channel group.

    Abstract: A method includes: A basic application layer sends first information that includes a first business requirement and a first port to a basic service layer. The basic service layer sends second information that includes the first business requirement, a first broadcast business channel, and a logical channel type to an access layer. The first broadcast business channel is determined based on the first information. The access layer supports a first access technology that is determined, based on the first business requirement, from a plurality of access technologies supported by the access layer. The access layer sends a first mapping relationship that indicates the first broadcast business channel and a first logical channel to the basic service layer. The first logical channel is a logical channel that supports the first access technology and that is determined based on the second information.

    Abstract: A point-to-multipoint data transmission method and device, the method including a left earbud and a right earbud of a true wireless stereo (TWS) headset separately performing pairing and service content negotiation with an electronic device. The left earbud receives left configuration information sent by the electronic device, to configure a left ISO channel, and the right earbud receives right configuration information sent by the electronic device, to configure a right ISO channel. The left earbud receives, based on the BLE-based audio profile, audio data that is sent by the electronic device through the left ISO channel, and the right earbud receives, based on the BLE-based audio profile, the audio data that is sent by the electronic device through the right ISO channel. The left earbud and the right earbud play the respectively received audio data based on a first timestamp.

    Abstract: A Bluetooth communication method is disclosed, and relates to the field of short-range wireless communications technologies. The method includes: A terminal receives a play operation performed by a user on first audio data. The terminal sends first indication information to a Bluetooth device when a service type of the first audio data is a first service type, where the first indication information is used by the Bluetooth device to set a buffer time length for the audio data to first duration. The Bluetooth device receives the first audio data sent by the terminal via Bluetooth, and buffers the first audio data. The Bluetooth device starts to play the buffered first audio data when the buffer time length for the first audio data reaches the first duration. In this way, the terminal can perform targeted delay control on audio data playback of the Bluetooth device in different application scenarios.
