In scenarios requiring the transmission of large amounts of data, such as when a voice recorder needs to transmit audio to a mobile terminal, or when firmware upgrades are needed for smart wearable devices, the slow data transmission speed leads to a poor user experience.

[0013] Figure 1This is a flowchart illustrating a file transfer optimization method based on dynamic channel remaining capacity awareness provided in an embodiment of the present invention. This embodiment is applicable to scenarios involving the transfer of large amounts of data via Bluetooth Low Energy. The method is applied to the file data holding device of the target file and can be executed by the file transfer optimization device based on dynamic channel remaining capacity awareness provided in this embodiment. This device can be implemented in software and / or hardware. In a specific embodiment, this device can be integrated into an electronic device, such as a computer or server. The following embodiments will illustrate this using the integration of this device into an electronic device as an example. (Reference) Figure 1 The method may specifically include the following steps: Step 101: In response to a file transfer request sent by the data access device, determine the data to be transferred and read the data into the transmission buffer. The data holding device is a Bluetooth Low Energy device and has established a Bluetooth connection with the data access device. This step facilitates pushing the data to be transferred to the Bluetooth channel between the data holding device and the data access device.

[0014] Specifically, the aforementioned data access device can be a Bluetooth Low Energy device or a regular Bluetooth device.

[0015] Specifically, the aforementioned data holding device can be either a master device or a slave device, and the aforementioned data access device can be either a master device or a slave device.

[0016] Specifically, the aforementioned slave device may be a wireless microphone, an AI voice recorder, or other such device, while the aforementioned master device may be a mobile phone or a tablet, or other such device.

[0017] Specifically, the file transfer request may include file identifier, file name, file path, and / or transfer length.

[0018] Specifically, the process of determining and transmitting data in response to a file transfer request sent by a data access device may include: determining the data to be transmitted based on the file name and / or file path.

[0019] Specifically, the process of reading the data to be transmitted into the sending buffer can include: reading the data to be transmitted into the sending buffer all at once or reading the data to be transmitted into the sending buffer in multiple parts.

[0020] Specifically, a Bluetooth connection between a data access device and a data holding device can be established through the following steps: After the slave device of the data access device and the data holding device are powered on, they initialize Bluetooth and enable Bluetooth function to send broadcast packets; the master device of the two devices starts scanning and, after capturing the broadcast signal of the data holding device, parses the connection-related parameters, completes device discovery and matching, and sends a connection request packet to the slave device; after receiving the connection request packet, the slave device agrees to the connection and returns a response, and both the master and slave devices synchronously enter the connected state.

[0021] Optionally, before determining the data to be transmitted and reading the data to be transmitted into the transmission buffer in response to a file transfer request sent by the data access device, the embodiments of the present invention further include: determining the minimum value of the real-time configurable communication cycle based on the acceptable minimum Bluetooth communication cycle of the data access device and the real-time network environment status, and configuring the current Bluetooth communication cycle as the minimum value of the real-time configurable communication cycle; and configuring the maximum length of the current Protocol Data Unit (PDU) between the data access device and the data holding device based on the maximum transmission unit (MTU) data volume of the data access device.

[0022] Specifically, when establishing a Bluetooth connection between the data access device and the data holding device, or after establishing a Bluetooth connection between the data access device and the data holding device, the minimum value of the real-time configurable communication period can be determined based on the acceptable minimum Bluetooth communication period of the data access device and the real-time network environment status, and the current Bluetooth communication period can be configured as the minimum value of the real-time configurable communication period; and the maximum length of the current protocol data unit between the data access device and the data holding device can be configured based on the maximum transmission unit data volume of the data access device.

[0023] Specifically, the real-time network environment status can be determined based on the signal strength and packet loss rate of broadcast packets before establishing a Bluetooth connection between the data access device and the data holding device.

[0024] Specifically, the minimum real-time configurable communication cycle can be determined based on the real-time network environment status, and the minimum real-time configurable communication cycle can be determined based on the acceptable minimum Bluetooth communication cycle of the data access device and the preliminary determination result.

[0025] Specifically, if the acceptable minimum Bluetooth communication cycle of the data access device is greater than the preliminary determination result, the acceptable minimum Bluetooth communication cycle of the data access device can be determined as the minimum real-time configurable communication cycle; otherwise, the preliminary determination result can be determined as the minimum real-time configurable communication cycle.

[0026] Specifically, when the data access device is a mobile phone, the maximum transmission unit (BYTE) data size can be determined based on the phone type. For example, when the phone type is an Android phone, the maximum BYTE data size can be set to 251 bytes, and when the phone type is an Apple phone, the maximum BYTE data size can be set to 180 bytes.

[0027] Specifically, the maximum length of the current protocol data unit of the configured data access device and data holding device can be set to be equal to the maximum transmission unit length of the data access device, or the maximum length of the current protocol data unit of the configured data access device and data holding device can be set to a specific proportion of the maximum transmission unit length of the data access device, such as 90-95% of the maximum transmission unit length of the data access device.

[0028] Specifically, the file transfer request sent by the data access device may include only one transfer round of file transfer request, so as to complete the transfer of all the data to be transferred corresponding to the target file within one transfer round.

[0029] Specifically, the file transfer request sent by the data access device may also include multiple transfer rounds of file transfer requests, so as to complete the transfer of all the data to be transferred corresponding to the target file in multiple transfer rounds.

[0030] Step 102: Real-time detection of remaining channel capacity based on the cache push cycle; the remaining channel capacity is the remaining data capacity of the Bluetooth channel between the data holding device and the data access device, and the cache push cycle is shorter than the current Bluetooth communication cycle between the data access device and the data holding device. This step enables the data in the transmission cache to be pushed to the Bluetooth channel between the data holding device and the data access device as quickly as possible based on the cache push cycle, which is shorter than the current Bluetooth communication cycle, so that the data access device can complete the reception of the data to be transmitted as quickly as possible.

[0031] Optionally, before step 102, the maximum data volume of the data access device is obtained and determined as the first data volume to improve the data transmission rate.

[0032] In a specific instance, when the data access device is an Apple mobile phone, the first data volume is determined to be 180 bytes.

[0033] Specifically, the first data volume can be set to a data volume slightly smaller than the maximum transmission unit data volume of the data access device, for example, it can be set to 90% of the maximum transmission unit data volume of the data access device, in order to reduce the risk of packet loss and improve transmission stability.

[0034] Specifically, the cache push cycle can be determined based on the current Bluetooth communication cycle before step 102.

[0035] Specifically, the cache push period can be preset to an empirical value, such as 1ms.

[0036] Specifically, when establishing a Bluetooth connection between a data access device and a data holding device, the maximum capacity of the Bluetooth channel can be configured by configuring the physical layer (PHY) data transmission rate.

[0037] Specifically, the process of real-time detection of channel remaining capacity based on the cache push cycle can include: real-time detection of the occupancy rate of the Bluetooth channel, and obtaining the channel remaining capacity based on the Bluetooth channel occupancy rate and the maximum capacity of the Bluetooth channel.

[0038] Specifically, the busy / idle status of the Bluetooth channel can be monitored using a Bluetooth packet capture device or a spectrum analyzer, and the occupancy rate of the Bluetooth channel can be determined based on the busy / idle status.

[0039] Specifically, you can also call the "HCI_CHANNEL_UTILIZATION event read" in the Bluetooth protocol stack to read the busy / idle status of the Bluetooth channel and determine the occupancy rate of the Bluetooth channel based on the busy / idle status.

[0040] Step 103: When the remaining channel capacity is greater than the first data volume, push the data to be transmitted from the transmit buffer to the Bluetooth channel until the transmit buffer no longer contains the data to be transmitted. This step, based on steps 101 and 102, significantly improves the transmission rate when transmitting large files via Bluetooth Low Energy, greatly enhancing the user experience.

[0041] Optionally, the file transfer optimization method based on dynamic channel remaining capacity awareness provided in this embodiment of the invention further includes: after pushing all the data to be transferred corresponding to the target file from the sending buffer to the Bluetooth channel, monitoring the packet loss retransmission request sent by the data access device and performing packet loss retransmission after detecting the packet loss retransmission request.

[0042] It is understandable that performing packet loss retransmission after completing all the data to be transmitted for the target file can help reduce the number of protocol interactions, reduce control overhead, compress retransmission timing costs, and improve transmission speed.

[0043] The following further introduces the file transfer optimization method based on dynamic channel remaining capacity awareness provided by the embodiments of the present invention.

[0044] Optional, such as Figure 2 As shown, if the file transfer request sent by the data access device only includes a file transfer request for one transfer round, the process of reading the data to be transferred into the send buffer in step 101 includes the following steps: Step 101A1: Real-time detection of remaining capacity of the sending cache based on the cache read cycle.

[0045] Specifically, the cache read cycle can be the same as the cache push cycle, or it can be different from the cache push cycle.

[0046] Step 101A2: When the remaining capacity of the sending buffer is greater than the second data amount, the data to be transmitted for the second data amount is read into the sending buffer until all the data to be transmitted corresponding to the target transmission file is read.

[0047] Specifically, the second data volume can be the same as or different from the first data volume.

[0048] Specifically, the second data volume can be set to be greater than the first data volume, and the cache read cycle can be set to be less than the cache push cycle, in order to reduce the overhead required for real-time detection and sending of the remaining cache capacity.

[0049] This embodiment is suitable for scenarios where the amount of data to be transferred corresponding to the target file is relatively small, and can help maximize the transfer rate when transferring the target file.

[0050] The following further introduces the file transfer optimization method based on dynamic channel remaining capacity awareness provided by the embodiments of the present invention.

[0051] Optionally, the file transfer request includes multiple request rounds of file transfer requests. Each request round of file transfer requests is used to request the file data of the target file to be transferred in a single round. Each request round of file transfer requests includes the file name of the target file to be transferred and the amount of data to be transferred in a single round.

[0052] Specifically, the amount of data transferred in a single round of file transfer requests in each request round can be the same or different.

[0053] Optional, such as Figure 3 As shown, that is Figure 1 Step 101 may include the following steps: Step 101B1: In response to the file transfer request in each request round, determine the memory space size of the sending buffer based on the amount of data transferred in a single round, and allocate the sending buffer based on the memory space size of the sending buffer.

[0054] Step 101B2: Determine the storage location of the data to be transmitted based on the file name, and read the data to be transmitted for a single round from the storage location into the sending buffer.

[0055] Specifically, steps 101B1 and 101B2 can be executed only in the first request round, while in other request rounds, only the data to be transmitted for a single round can be read from the storage location into the send buffer.

[0056] Specifically, such as Figure 4 As shown, the data access device can check whether it has successfully received the data to be transmitted sent by the data holding device in that request round after the end of any request round. If it has not successfully received the data, it can send a data retransmission request for that request round to the data access device.

[0057] Optional, such as Figure 4 As shown, the file transfer optimization method based on dynamic channel remaining capacity awareness provided in this embodiment of the invention further includes: when receiving a data retransmission request for any request round sent by the data access device, re-initiating the execution of reading the data to be transmitted for the single round of data requested for retransmission from the storage location into the sending buffer.

[0058] Optional, such as Figure 4 As shown, after successfully receiving the data to be transmitted sent by the data holding device in any request round, the data access device can check whether the transmission of all the data to be transmitted corresponding to the target file has been completed. If not, it sends a file transmission request for the next request round to the data holding device. If completed, it checks whether all the data to be transmitted has been lost. If packet loss has occurred, it sends a packet loss retransmission request to the data holding device. If no packet loss has occurred, it ends the transmission of the target file.

[0059] This embodiment is applicable to scenarios where the target file to be transmitted has a large amount of data to be transmitted. It can improve the transmission rate while avoiding problems such as retransmission errors that may be caused by excessive packet loss during the final packet loss and retransmission.

[0060] The following further introduces the file transfer optimization method based on dynamic channel remaining capacity awareness provided by the embodiments of the present invention.

[0061] Optionally, if a file transfer request can also include multiple transfer rounds of file transfer requests, then when responding to the file transfer requests for each request round, such as... Figure 5 As shown, it may include the following steps: Step 501: Determine the maximum allowed space for the send buffer based on real-time available local resources.

[0062] Specifically, the aforementioned real-time locally available resources include the idle RAM capacity, CPU load rate, and remaining cache quota of the Bluetooth protocol stack of the data holding device acquired in real time.

[0063] Specifically, before determining the maximum allowable space of the transmission buffer based on real-time available local resources, the total number of buffered data packets that the corresponding Bluetooth channel can carry can be calculated based on the current maximum length of the protocol data unit between the data access device and the data holding device, the number of packets that can be transmitted within a connection event, and the link packet loss rate. The process of determining the maximum allowable space of the transmission buffer based on real-time available local resources can include: determining the maximum allowable space of the transmission buffer based on real-time available local resources and the total number of buffered data packets that the corresponding Bluetooth channel can carry.

[0064] Step 502: Send the maximum allowed space of the sending cache to the data access device so that the data access device can determine the amount of data transmitted in a single round of the current request round based on the maximum allowed space of the sending cache.

[0065] Specifically, the data access device can determine the amount of data transmitted in a single round of the current request round to be less than the amount of data that the maximum allowed space of the sending buffer can hold.

[0066] Step 503: In response to the file transfer request of the current request round, determine the memory space size of the current round's sending cache based on the single round's data transfer volume of the current request round, and allocate the current sending cache based on the memory space size of the current round's sending cache.

[0067] Step 504: Determine the storage location of the data to be transmitted based on the file name, and read the data to be transmitted for the current request round from the storage location into the current sending cache.

[0068] Step 505: Real-time detection of remaining channel capacity based on cache push cycle.

[0069] Step 506: When the remaining channel capacity is greater than the first data amount, push the data to be transmitted from the current transmit buffer to the Bluetooth channel until there is no data to be transmitted in the current transmit buffer.

[0070] This invention, through determining the maximum allowed space of the sending cache based on real-time available local resources, enables the data access device to determine the amount of data transmitted in a single round of the current request based on the maximum allowed space of the sending cache. This further facilitates the improvement of data transmission rate while ensuring system stability.

[0071] Figure 6 This is a structural diagram of a file transfer optimization device based on dynamic channel remaining capacity awareness provided in an embodiment of the present invention. This device is integrated into a file data holding device for the target file transfer and is suitable for executing the file transfer optimization method based on dynamic channel remaining capacity awareness provided in an embodiment of the present invention. Figure 6 As shown, the device may specifically include: The cache module 601 is used to determine the data to be transmitted in response to a file transfer request sent by the data access device and read the data to be transmitted into the transmission cache. The data holding device is a Bluetooth Low Energy device and has established a Bluetooth connection with the data access device.

[0072] Optionally, the file transfer request includes multiple request rounds of file transfer requests. Each request round of file transfer requests is used to request the file data of the target file to be transferred in a single round. Each request round of file transfer requests includes the file name of the target file to be transferred and the amount of data to be transferred in a single round.

[0073] Optionally, the aforementioned caching module 601 can be specifically used to detect the remaining capacity of the sending cache in real time based on the cache reading cycle; and when the remaining capacity of the sending cache is greater than the second data amount, read the data to be transmitted of the second data amount into the sending cache until all the data to be transmitted corresponding to the target transmission file is read.

[0074] Optionally, the aforementioned caching module 601 can be specifically used to: determine the memory space size of the sending cache based on the amount of data transmitted in a single round in response to the file transfer request of each request round; allocate the sending cache based on the memory space size of the sending cache; and determine the storage location of the data to be transmitted based on the file name, and read the data to be transmitted in a single round from the storage location into the sending cache.

[0075] Optionally, the aforementioned caching module 601 can also be specifically used to determine the maximum allowed space of the sending cache based on real-time available local resources; and to send the maximum allowed space of the sending cache to the data access device, so that the data access device can determine the amount of data transmitted in a single round of the current request round based on the maximum allowed space of the sending cache.

[0076] The channel remaining capacity detection module 602 is used to detect the channel remaining capacity in real time based on the cache push cycle; the channel remaining capacity is the remaining data capacity of the Bluetooth channel between the data holding device and the data access device, and the cache push cycle is less than the current Bluetooth communication cycle between the data access device and the data holding device.

[0077] The push module 603 is used to push the data to be transmitted from the transmit buffer to the Bluetooth channel when the remaining channel capacity is greater than the first data amount, until the transmit buffer no longer contains the data to be transmitted.

[0078] Optionally, the file transfer optimization device based on dynamic channel remaining capacity awareness provided in this embodiment of the invention further includes: a packet loss retransmission module, which is used to monitor the packet loss retransmission request sent by the data access device and perform packet loss retransmission after monitoring the packet loss retransmission request after pushing all the data to be transmitted corresponding to the target file from the sending buffer to the Bluetooth channel.

[0079] Optionally, the file transfer optimization device based on dynamic channel remaining capacity awareness provided in this embodiment of the invention further includes: a first data volume determination module, used to obtain and determine the maximum transmission unit data volume of the data access device as the first data volume before pushing the first data volume of data to be transmitted from the transmission buffer to the Bluetooth channel when the channel remaining capacity is greater than the first data volume.

[0080] Optionally, the file transfer optimization device based on dynamic channel remaining capacity awareness provided in this embodiment of the invention further includes a configuration module, used to determine the minimum real-time configurable communication period based on the minimum acceptable Bluetooth communication period of the data access device and the real-time network environment status before determining the data to be transferred and reading the data to be transferred into the transmission buffer in response to the file transfer request sent by the data access device, and configure the current Bluetooth communication period as the minimum real-time configurable communication period; and configure the maximum length of the current protocol data unit between the data access device and the data holding device based on the maximum transmission unit data volume of the data access device.

[0081] This invention provides a file transfer optimization method, apparatus, electronic device, and storage medium based on dynamic channel remaining capacity awareness. It determines the data to be transferred in response to a file transfer request sent by a data access device and reads the data into a sending buffer. Based on a buffer push cycle, it detects the channel remaining capacity in real time, and when the channel remaining capacity is greater than a first data amount, it pushes the first data amount of data to be transferred from the sending buffer to the Bluetooth channel until the sending buffer no longer contains the data to be transferred. This significantly improves the transfer rate when transferring large files via Bluetooth Low Energy, greatly enhancing the user experience.
