[0002] Bluetooth technology is a widely used short-range wireless communication technology, widely adopted due to its convenience in data transmission. However, its relatively short transmission distance limits its application range. Related technologies increase the transmission distance by enhancing the transmission power between Bluetooth devices, but this method increases the power consumption of the Bluetooth devices. Furthermore, if obstacles exist in the transmission path, signal fading can cause stuttering. Therefore, there is an urgent need to provide a method to improve the data transmission distance between Bluetooth devices. Summary of the Invention

[0032] Figure 7 This is a schematic diagram of the structure of an electronic device according to an exemplary embodiment of the present disclosure. Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0034] Due to its low-power characteristics, Bluetooth wireless communication technology is increasingly being adopted by various devices. However, Bluetooth's transmission distance is relatively short. Related technologies aim to increase the transmission distance by enhancing the transmission power between Bluetooth devices. For example, Bluetooth Super achieves longer-distance transmission by increasing the Bluetooth transmission power between the phone and headphones. However, this approach increases the power consumption of the Bluetooth antenna, thus reducing the headphones' battery life.

[0035] Therefore, this disclosure provides a Bluetooth-based data transmission method, and in this disclosure, the two devices connected via Bluetooth are referred to as the "source device" and the "target device," respectively. Please refer to... Figure 1a and Figure 1b , Figure 1a and Figure 1b This is a schematic diagram of a scenario illustrated in this disclosure according to an exemplary embodiment, in which the target device... Figure 1a The location where it is located is moved to Figure 1bIn this context, the method of extending the Bluetooth transmission distance between the source and target devices involves using a router to forward the interactive data between them. Specifically, during Bluetooth data transmission between the source and target devices, if the source device receives signal strength information from the router that meets preset conditions, it indicates that the target device is closer to the router or that the communication quality between the target device and the router is better. Therefore, the source device can send a connection command to the router to establish a Bluetooth connection with the target device and send the data to be transmitted to the router, which then forwards the data to the target device. This method also extends the Bluetooth transmission distance between the source and target devices when the communication quality between them is poor, by using a router to forward the data to be transmitted.

[0036] The router disclosed herein supports Bluetooth functionality, enabling it to establish Bluetooth connections with both source and target devices. Furthermore, the router supports data relay services for forwarding data to be transmitted.

[0037] The following embodiments will first describe the data transmission method provided in this disclosure in general terms, with reference to the accompanying drawings. That is, the interaction process between the source device, the target device and the router will be introduced first, and then the data transmission method will be introduced from the perspectives of the source device and the router respectively.

[0038] Figure 2 This disclosure illustrates an interaction flowchart between a source device, a target device, and a router according to an exemplary embodiment, such as... Figure 2 As shown, the data transmission method provided in this disclosure may include the following steps 201 to 207.

[0039] In step 201, the source device and the target device transmit data via Bluetooth.

[0040] For example, a source device can send a high-quality stereo audio stream, namely an A2DP (Advanced Audio Distribution Profile) stream, to a target device. A2DP is the Bluetooth audio transmission protocol.

[0041] In step 202, the target device sends a broadcast signal.

[0042] In step 203, when the router receives a broadcast signal sent by the target device, it determines the signal strength information of the communication between the router and the target device and sends it to the source device.

[0043] When the router receives a broadcast signal from the target device, it measures the strength of the signal and sends the signal strength information to the source device.

[0044] In step 204, the source device receives the signal strength information sent by the router and determines whether the signal strength information meets the preset conditions. If the signal strength information meets the preset conditions, it sends a connection command to the router.

[0045] The signal strength information sent by the source device through the router can be used to assess the signal quality and communication stability between the router and the target device.

[0046] For example, in this embodiment, it can be determined whether the received signal strength of communication between the router and the target device is greater than the received signal strength of communication between the source device and the target device. If the received signal strength of communication between the router and the target device is greater than the received signal strength of communication between the source device and the target device, then the signal strength information is determined to meet the preset conditions. As another example, in this embodiment, it can be determined whether the received signal strength of communication between the router and the target device is within a preset range. If the received signal strength of communication between the router and the target device is within the preset range, then the signal strength information is determined to meet the preset conditions. The preset range can be set to -60dBm to -70dBm.

[0047] Those skilled in the art will understand that the signal strength information disclosed herein may include RSSI (Received Signal Strength Indicator), or other parameters besides RSSI used to measure signal quality between devices, and is not limited herein.

[0048] In step 205, the router receives the connection command and establishes a Bluetooth connection with the target device.

[0049] In step 206, the source device sends the data to be transmitted to the router.

[0050] In step 207, the router forwards the data to be transmitted to the target device.

[0051] This disclosure effectively extends the transmission distance between the source and target devices by using a router relay when the target device is far from the source device, thereby reducing stuttering issues caused by the increased distance.

[0052] In this embodiment, for the source device, the data transmission method provided in this disclosure may include: when the source device and the target device are transmitting data via Bluetooth, if the source device receives signal strength information sent by the router, it determines whether the signal strength information meets preset conditions. The signal strength information is sent to the source device by the router upon receiving a broadcast signal from the target device, and the signal strength information characterizes the received signal strength for communication between the router and the target device. If the signal strength information meets the preset conditions, a connection command is sent to the router to establish a Bluetooth connection between the router and the target device. Data to be transmitted is then sent to the router, causing the router to forward the data to be transmitted to the target device.

[0053] In this embodiment, for a router, the data transmission method provided in this disclosure may include: when the router receives a broadcast signal sent by a target device, sending signal strength information to a source device that has established a Bluetooth connection with the target device, the signal strength information being used to characterize the received signal strength for communication between the router and the target device; when the router receives a connection command, establishing a Bluetooth connection with the target device, the connection command being sent by the source device to the router after determining that the signal strength information meets preset conditions; receiving data to be transmitted sent by the source device, and forwarding the data to be transmitted to the target device.

[0054] This disclosure improves the limited range of Bluetooth devices (such as Bluetooth headsets) by relaying data to be transmitted through a router, so that the signal strength of the data to be transmitted received by the target device is maintained in a better state, thereby reducing the stuttering caused by signal fading.

[0055] In this embodiment of the disclosure, the target device supports the same account quick connection function, which allows devices under the same account to achieve fast Bluetooth pairing and connection through a simplified authentication process.

[0056] Figure 3 This disclosure illustrates a flowchart of a quick connection for the same account according to an exemplary embodiment, such as... Figure 3 As shown, the devices establish a connection through the following steps 301 to 305.

[0057] In step 301, after the source device and the target device establish a Bluetooth connection, the source device generates an account key associated with the user account.

[0058] In step 302, the source device sends the account key to the target device and all routers in the same local area network.

[0059] In step 303, the target device receives the account key and carries the account key when sending a broadcast signal.

[0060] In step 304, the router completes the registration of the account key.

[0061] In step 305, if the router detects a broadcast signal sent by the target device, it obtains the account key in the broadcast signal and matches it with the registered account key. If they match, the router obtains the signal strength information between itself and the target device.

[0062] This disclosure enables a quick connection between the router and the target device via Bluetooth's same-account quick connection function, preparing for the seamless transition of data from the source device to the target device through the router.

[0063] For the source device, when a Bluetooth connection is established between the source device and the target device, the source device generates an account key associated with the user account. The account key is used to enable Bluetooth connections between devices under the user account. The source device sends the account key to the target device, so that the target device carries the account key when sending broadcast signals. The source device synchronizes the account key to all routers in the same local area network, so that each router completes the registration of the account key.

[0064] After the source device and target device successfully pair for the first time, an account key associated with the user account will be generated and sent to the target device and all routers in the same local area network. This allows the target device to quickly establish connections with different routers as it moves, thereby enabling the data sent by the source device to be forwarded to the target device through the router, thus extending the Bluetooth transmission distance.

[0065] For the target device, if the account key in the received broadcast signal matches the pre-registered account key, a connection request is sent to the target device. The account key is generated and sent to the router for registration when the source device establishes a Bluetooth connection with the target device; the signal strength information between the router and the target device is obtained.

[0066] Since different target devices support different encoding capabilities, such as AptX, LHDC, and AAC, but routers cannot adapt to all encoding capabilities, this disclosure involves the source device sending encoding configuration information to the router. The router then forwards this information to the target device, allowing the target device to switch to the appropriate encoding based on the configuration information. Afterward, the source device sends the encoded data to the router, which then transmits the data to the target device via Bluetooth. This method eliminates the need for the router to support all encoding capabilities of the Bluetooth protocol, thus achieving the desired solution.

[0067] For the source device, before sending the data to be transmitted to the router, the method further includes: sending encoding configuration information to the router, causing the router to forward it to the target device, wherein the encoding configuration information is used to indicate the encoding format of the data to be transmitted sent to the target device through the router; and receiving a configuration success notification sent by the router, wherein the configuration success notification is sent by the target device to the router after completing the encoding configuration.

[0068] For the target device, before receiving the data to be transmitted sent by the source device, the method further includes: receiving encoding configuration information sent by the source device and forwarding it to the target device, wherein the encoding configuration information is used to indicate the encoding format of the data to be transmitted sent to the target device through the router; and receiving a configuration success notification sent by the target device and forwarding it to the source device.

[0069] Upon receiving the encoded configuration information from the source device, the router forwards the information to the target device. The target device then performs the encoding configuration according to the instructions in the information and, upon completion, sends a configuration success notification to the router. The router receives and forwards the configuration success notification to the source device, which, upon receiving it, sends the data to be transmitted to the router.

[0070] In some embodiments, where the data to be transmitted includes an audio stream, for the source device, sending the data to be transmitted to the router, causing the router to forward the data to be transmitted to the target device, may include: sending an audio stream to both the router and the target device; and, upon receiving a disconnect command from the router, stopping sending the audio stream to the target device and disconnecting the Bluetooth connection with the target device, wherein the disconnect command is sent to the source device by the router when it forwards the audio stream to the target device.

[0071] To ensure uninterrupted audio streaming to the target device, the source device simultaneously sends audio streams to both the router and the target device without receiving a disconnect command from the router. Upon receiving the disconnect command from the router, the source device stops sending audio streams to the target device and disconnects the Bluetooth connection with the target device. Since the disconnect command is sent from the router to the source device while forwarding the audio stream to the target device, and is triggered by the target device upon initiating audio transmission, the target device can stop receiving audio streams from the source device and begin receiving audio streams from the router upon receiving the audio stream sent by the router. This achieves seamless transition between the audio streams sent by the source device and those forwarded by the router.

[0072] It should be noted that in this embodiment, before sending the audio stream to the router, the source device continuously sends the audio stream to the target device based on the Bluetooth continuity between the source and target devices. In one implementation, the source device can send audio streams to both the router and the target device simultaneously after sending a connection command and before receiving a disconnect command from the router.

[0073] In some embodiments, where the data to be transmitted includes an audio stream, for the router, receiving the data to be transmitted sent by the source device and forwarding the data to be transmitted to the target device may include: upon receiving the audio stream sent by the source device, sending an audio transmission start request to the target device; upon receiving an audio transmission start ready response sent by the target device, sending the audio stream to the target device, causing the target device to stop receiving the audio stream sent by the source device and start receiving the audio stream sent by the router upon receiving the audio stream sent by the router; and sending a disconnect command to the source device, causing the source device to disconnect its Bluetooth connection with the target device.

[0074] In the Bluetooth protocol, before a router can send an audio stream to a target device, it must first send an Audio / Video Distribution Transport Protocol Start (AVDTP Start) request. Once ready, the target device sends an AVDTP Start complete response to the router. Upon receiving this response, the router begins sending the audio stream to the target device. This causes the target device to stop playing the audio stream from the source device and begin playing the router's audio stream.

[0075] Although the target device stops receiving the audio stream from the source device, the Bluetooth link between the target and source devices remains open. Therefore, when the router starts sending an audio stream to the target device, it sends a disconnect command to the source device, causing the source device to disconnect from the target device's Bluetooth connection. The Bluetooth link between the target and source devices can be a Bluetooth connection link based on ACL communication mode. ACL is a link type in Bluetooth technology used for transmitting asynchronous data, supporting point-to-point and point-to-multipoint connections.

[0076] For ease of understanding, the following embodiments use a mobile phone as the source device and a Bluetooth headset as the target device as an example. Figure 4 The process of transmitting audio streams as disclosed herein is explained.

[0077] Figure 4 This disclosure is a schematic diagram illustrating the transmission of an audio stream according to an exemplary embodiment, such as... Figure 4 As shown, audio streams are transmitted between the mobile phone and the headphones through steps 401 to 409.

[0078] In step 401, the router sends signal strength information to the mobile phone. This signal strength information characterizes the received signal strength during communication between the router and the headset.

[0079] In step 402, the mobile phone sends a connection command to the router after determining that the signal strength information meets the preset conditions.

[0080] In step 403, the router establishes a Bluetooth connection with the headset according to the connection command.

[0081] In step 404, the mobile phone sends configuration encoding information to the router, causing the router to forward the configuration encoding information to the headset.

[0082] In step 405, the router receives the configuration success notification sent by the headset and forwards it to the mobile phone.

[0083] In step 406, the mobile phone simultaneously sends audio streams to both the router and the headset.

[0084] In step 407, the router sends a request to the headphones to initiate audio transmission.

[0085] In step 408, upon receiving an audio transmission start-ready response from the headphones, the router sends an audio stream to the headphones and sends a disconnect command to the mobile phone.

[0086] In step 409, upon receiving a disconnect command, the mobile phone disconnects from the Bluetooth connection with the headset.

[0087] In Bluetooth communication, Bluetooth devices can transfer files via the OPP (Object Push Profile) protocol. This means that the data to be transferred can also include text streams.

[0088] When the data to be transmitted includes a text stream, for the source device, sending the data to be transmitted to the router so that the router forwards the data to the target device may include: stopping sending the current frame in the text stream to the target device; and, upon receiving a data request sent by the router, sending the current frame and subsequent frames to the router, wherein the data request is generated by the router in response based on the number of the current frame sent by the target device.

[0089] Because the text stream is divided into multiple frames for transmission, the source device can stop sending the current frame of the text stream to the target device after sending a connection command to the router, thus avoiding data loss due to poor communication quality between the source and target devices. Upon receiving a data request from the router, the source device begins sending the current frame and subsequent frames to the router, causing the router to forward the current frame and subsequent frames to the target device.

[0090] In some embodiments, where the data to be transmitted includes a text stream, for the router, before receiving the data to be transmitted sent by the source device, the method further includes: sending a request for the number of the current frame in the text stream to the target device, and receiving a response for the number of the current frame sent by the target device; sending a data request to the source device based on the response for the number of the current frame, causing the source device to send the current frame indicated by the number and other frames thereafter.

[0091] For a router, to ensure the target device receives all frames in the text stream, it sends a request to the target device for the number of the current frame in the text stream that the target device is currently preparing to receive, and receives a response from the target device with the number of the current frame. The target device can determine the number of the current frame according to a preset strategy; for example, if it has not received all the data of the current frame, it discards the already received data and sends the number of the current frame to the router.

[0092] For ease of understanding, the following embodiments are combined with Figure 5 The process of transmitting text streams is explained.

[0093] Figure 5 This disclosure illustrates a text stream transmission diagram according to an exemplary embodiment, such as... Figure 5 As shown, the text stream is transmitted through the following steps 501 to 506.

[0094] In step 501, the source device sends the total size of the file to be transmitted, the size of each frame, and the total number of frames to be transmitted to the target device, and transmits the data based on the Bluetooth connection.

[0095] In step 502, the router sends signal strength information to the source device. This signal strength information characterizes the received signal strength during communication between the router and the target device.

[0096] In step 503, if the source device determines that the signal strength information meets the preset conditions, it sends a connection command to the router and stops sending the current frame in the text stream to the target device.

[0097] In step 504, the router establishes a Bluetooth connection with the target device according to the connection command and sends a request for the number of the current frame in the text stream to the target device.

[0098] Align the current transmission frame number by sending a request for the current frame number in the text stream to the target device.

[0099] In step 505, the router receives the current frame number response sent by the target device and sends a data request to the source device based on the current frame number response.

[0100] In step 506, the source device sends the current frame and subsequent frames to the router, causing the router to forward them to the target device.

[0101] When a source device sends data to a target device via a router, if the target device disconnects, the router, upon receiving the disconnection information from the target device, sends a target device disconnection notification to the source device, causing the source device to stop sending data. For example, after the target device disconnects, it can send "HCI_remote_disconnect" to the router to indicate that the remote Bluetooth device, i.e., the target device, has been disconnected.

[0102] For the source device, upon receiving a target device disconnection notification from the router, it stops sending data to be transmitted. The target device disconnection notification is forwarded by the router to the source device upon receiving disconnection information from the target device.

[0103] When a router and target device establish a connection based on the Audio / Video Remote Control Profile (AVRCP), since the source device and target device have lost their Bluetooth connection, the button operation events of the target device will be forwarded to the source device through the router. In this embodiment, an AVRCP control command is mapped in the router via the network so that the target device can operate the functions of the source device. For example, if the source device is a terminal device and the target device is a headset, the user can control the playback or pause of music on the terminal device through button operation events on the headset side.

[0104] In other words, for the source device, upon receiving a control command from the router, it executes a corresponding control operation according to the instruction of the control command. The control command is obtained by the router encapsulating a button operation event sent by the target device according to a pre-set mapping rule. The button operation event includes at least one of a play event, a pause event, and a volume adjustment event.

[0105] For a router, upon receiving a key operation event sent by the target device, it encapsulates the key operation event into a control command according to a pre-set mapping rule, and sends the control command to the source device, so that the source device performs the corresponding control operation according to the instruction of the control command.

[0106] Figure 6 This disclosure is a schematic diagram illustrating data transmission between a mobile phone and an earphone according to an exemplary embodiment, as shown below. Figure 6 As shown, when the headphones are disconnected after being put back in the case, they send a disconnection message to the router. The router then sends a headphone disconnection notification to the phone, causing the phone to stop sending audio streams. Conversely, if the headphones reconnect after being opened from the case, i.e., after establishing a Bluetooth connection with the router, they can send button operation events to the router. The router will then generate corresponding control commands based on the mapping relationship and send them to the phone, thereby enabling media playback control via the headphone buttons.

[0107] like Figure 6 As shown, the data to be transmitted between the source device and the destination device can be relayed through at least one router. In a local area network (LAN), the process of relaying data through multiple routers is described in the TCP / IP protocol, and will not be repeated in this embodiment.
