Description

Technical Field

[0001] This invention relates to the field of communication technology, and more specifically to a communication module switching method, apparatus, electronic device, and storage medium. Background Technology

[0002] With the improvement of living standards and the development of science and technology, devices that can transmit data through short-range communication are being used more and more widely in people's lives, and people's requirements for data transmission between devices are getting higher and higher.

[0003] Currently, relying solely on a single short-range communication method for data transmission cannot meet users' high demands for data transfer. For example, some short-range communication methods suffer from high latency and data corruption due to compression caused by low bandwidth. Others are prone to significant latency due to issues such as co-frequency interference and contention for transmission channel resources. Therefore, using only one short-range communication method will negatively impact the user's data transmission experience and cannot guarantee low-latency, high-quality data transmission in various scenarios.

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] This invention provides a communication module switching method, apparatus, electronic device, and computer-readable storage medium. Specifically, this invention provides a communication module switching method applicable to a communication module switching apparatus, which can be integrated into an electronic device.

[0055] The electronic device can be a terminal or other device, including but not limited to mobile terminals and fixed terminals. For example, mobile terminals include but are not limited to smartphones, smartwatches, tablets, laptops, smart vehicles, etc., while fixed terminals include but are not limited to desktop computers, smart TVs, etc.

[0056] The electronic device can also be a server or other similar device. The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms, but it is not limited to these.

[0057] The communication module switching method of this invention can be implemented by the terminal or by both the terminal and the server.

[0058] The following example illustrates the method of switching communication modules using both a terminal and a server.

[0059] like Figure 1As shown, the communication module switching system provided in this embodiment of the invention includes a terminal 10 and a server 20, etc.; the terminal 10 and the server 20 are connected through a network, such as through a wired or wireless network, etc., wherein the terminal 10 can exist as a terminal for a user to request data from the server 20.

[0060] The server 20 can be used to store target data and send target data to the terminal 10, etc.

[0061] Terminal 10 can be used to obtain the power-on time deviation between server 20 and terminal 10. It receives target data sent by server 20 through a first short-range communication module that establishes a connection with server 20. The target data includes the first power-on time of server 20 when the target data is sent. Based on the first power-on time and the power-on time deviation, the second power-on time of terminal 10 when the target data is sent is determined. The third power-on time of terminal 10 when the target data is received is determined. Based on the second power-on time and the third power-on time, the transmission time of the target data is calculated. If the transmission time is greater than a preset transmission time threshold, a connection is established with server 20 through the second short-range communication module, and data is transmitted through the second short-range communication module.

[0062] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the preferred order of the embodiments.

[0063] This invention will be described from the perspective of a communication module switching device, which can be integrated into a server or terminal.

[0064] like Figure 2 As shown, the specific process of the communication module switching method in this embodiment can be as follows:

[0065] 201. Obtain the power-on time deviation between the data sending end and the data receiving end.

[0066] In this context, the data sender is an electronic device capable of sending data to other devices. The data sender may store data requested by other devices, or it may retrieve requested data from certain storage locations based on requests from other devices.

[0067] Specifically, a data receiver is an electronic device capable of requesting data from a data sender and receiving data sent by the data sender. Generally, a data receiver can support at least two different short-range communication methods.

[0068] For example, the data sender can be a smartphone, and the data receiver can be a smart vehicle. The smart vehicle can have at least two short-range communication functions, such as WiFi, Bluetooth, NFC, and infrared transmission. The smart vehicle can actively request certain data from the smartphone based on user operations, or it can passively receive data sent by the smartphone. When sending data, the smartphone can select certain data from its own stored data or download data from the internet, and so on.

[0069] The boot-up time deviation refers to the difference in boot-up time between the data sending end and the data receiving end.

[0070] It is understandable that the power-on times of the data sending end and the data receiving end may not be the same. Correspondingly, during data transmission, the time elapsed from the power-on time of the data sending end to that time at the same moment will also differ from the time elapsed for the data receiving end. To quantify this difference, the power-on time deviation can be calculated at a specific time. That is, the step "obtaining the power-on time deviation between the data sending end and the data receiving end" can include:

[0071] Obtain the time synchronization data packet corresponding to the current time. The time synchronization data packet includes the power-on duration of the data sender and the data receiver.

[0072] Based on the power-on duration, calculate the power-on duration deviation between the data sending end and the data receiving end corresponding to the time point.

[0073] Among them, the time synchronization data packet can be a data packet sent from the data sender to the data receiver.

[0074] In addition to the power-on duration of the data sender and receiver, the time synchronization data packet may not include other data. Alternatively, in addition to the power-on duration of the data sender and receiver, the time synchronization data packet may also include the target data that the data sender needs to send to the data receiver in order to save transmission resources.

[0075] It is understood that the time synchronization data packet is not necessarily sent by the data sender at the exact time of time synchronization; it can also be generated and sent by the data sender based on certain operations at the time of time synchronization. In some optional embodiments, the step "obtaining the time synchronization data packet corresponding to the time synchronization moment" may specifically include:

[0076] Obtain the first time synchronization power-on duration of the time synchronization data receiving end;

[0077] The first time synchronization power-on duration is sent to the data sending end, triggering the data sending end to determine the second time synchronization power-on duration when the first time synchronization power-on duration is received. An initial time synchronization data packet is generated based on the first time synchronization power-on duration and the second time synchronization power-on duration. When sending the initial time synchronization data packet to the data receiving end, the third time synchronization power-on duration of the data sending end at the sending time is added to the initial time synchronization data packet to obtain the time synchronization data packet.

[0078] Receive time synchronization data packets.

[0079] In other words, such as Figure 3 As shown, at the time synchronization point, the data receiving end determines the time T1 that has elapsed since its own power-on, i.e., the first time synchronization power-on duration, and sends T1 to the data sending end. After receiving T1, the data sending end determines the time T2 that has elapsed since its own power-on at the time of receiving T1, i.e., the second time synchronization power-on duration.

[0080] The data sender assembles T1 and T2 into an initial time synchronization data packet, ready to send it via short-range communication. During transmission, the data sender adds the elapsed time T3 since its power-on (the third time since power-on) to the initial time synchronization data packet, thus obtaining the final time synchronization data packet. The data sender then sends the time synchronization data packet to the data receiver.

[0081] In practical applications, time synchronization can be calculated using the time difference between the data receiver and the data sender based on the power-on duration when the time synchronization data packet is received by the data receiver and the time intervals T1, T2, and T3 in the time synchronization data packet. Therefore, before the step "calculate the power-on duration deviation between the data sender and the data receiver at the corresponding time synchronization moment based on the power-on duration", the communication module switching method provided in this embodiment of the invention may further include:

[0082] Determine the fourth time synchronization startup duration of the data receiving end when receiving time synchronization data packets;

[0083] Accordingly, the step "calculate the power-on duration deviation between the data sending end and the data receiving end corresponding to the time interval based on the power-on duration" can specifically include:

[0084] Based on the first, second, third, and fourth time synchronization startup durations in the time synchronization data packet, calculate the startup duration deviation between the data sending end and the data receiving end corresponding to the time synchronization moment.

[0085] For example, assuming that the uplink and downlink data transmission are symmetrical, i.e., the network round-trip time is equal, the power-on time deviation Toffset can be calculated using the following formula:

[0086] Toffset = ((T2+T3)-(T1+T4)) / 2

[0087] At this point, Toffset represents the difference between the power-on time of the data sending end and the power-on time of the data receiving end.

[0088] Alternatively, the boot time deviation Toffset can also be calculated using the following formula:

[0089] Toffset = ((T1+T4)-(T2+T3)) / 2

[0090] At this point, Toffset represents the difference between the power-on time of the data receiving end and the power-on time of the data sending end.

[0091] The power-on durations of the first, second, third, and fourth time synchronization pairs, as well as the power-on duration deviation, can be expressed in milliseconds. This embodiment of the invention does not limit the form of this expression.

[0092] It is understandable that, considering the impact of network fluctuations and uplink / downlink asymmetry, when calculating the power-on time deviation, the time spent transmitting data back and forth between the data sending and receiving ends can be considered, and the power-on time deviation can be averaged or otherwise processed. That is, before the step "calculating the power-on time deviation between the data sending end and the data receiving end corresponding to the time synchronization time based on the first, second, third, and fourth time synchronization power-on times in the time synchronization data packet," the communication module switching method provided in this embodiment of the invention may further include:

[0093] Based on the first, second, third, and fourth time synchronization startup durations in the time synchronization data packet, the bidirectional data transmission time between the data receiver and the data sender is determined.

[0094] Specifically, the bidirectional data transmission time Tdelay can be calculated using the following formula:

[0095] Tdelay = T4 - T1 - (T3 - T2)

[0096] In other words, Tdelay actually represents the total time for transmitting a set of data between the data receiving end and the data sending end, minus the time for the data sending end to perform packet assembly and other processing. That is, Tdelay represents the time it takes for data to be transmitted back and forth between the data sending end and the data receiving end once.

[0097] Accordingly, the step "calculating the power-on duration deviation between the data sender and receiver at the corresponding time synchronization moment based on the first, second, third, and fourth time synchronization power-on durations in the time synchronization data packet" can specifically include:

[0098] If the bidirectional data transmission time is not greater than the preset bidirectional data transmission time threshold, based on the bidirectional data transmission time and the first, second, third, and fourth time synchronization startup times in the time synchronization data packet, calculate the startup time deviation between the data sending end and the data receiving end corresponding to the time synchronization moment.

[0099] In practical applications, if the bidirectional data transmission time is not greater than the preset bidirectional data transmission time threshold, the calculation error for the boot time deviation can be considered small. In this case, the calculated value can be directly used as the boot time deviation.

[0100] If the bidirectional data transmission time exceeds the preset bidirectional transmission time threshold, it can be considered that the calculation error of the boot time deviation is large. In this case, the historical boot time deviations obtained from several previous calculations can be obtained, and the average value of the current boot time deviation and the historical boot time deviations can be calculated. The result of the average value calculation is taken as the true boot time deviation to reduce the impact of factors such as network fluctuations.

[0101] 202. Receive target data sent by the data sender through the first short-range communication module that establishes a connection with the data sender. The target data includes the first power-on duration of the data sender when the target data is sent.

[0102] Among them, the first short-range communication module is a module in the data receiving end that can realize short-range communication function.

[0103] Specifically, the target data can be specific data requested by the data receiver from the data sender, or it can be data sent by the data sender to the data receiver.

[0104] Optionally, the target data can be audio data, text data, image data, video data, etc. The embodiments of the present invention do not limit the form and content of the target data.

[0105] The first power-on duration is the time elapsed from the power-on time of the data sending end to the time when the target data is sent.

[0106] In some optional embodiments, the target data can be audio frame data, and correspondingly, the data sender is the audio source sender, which can send audio frame data to the data receiver. For example, a user can choose to send a song or a chat voice message to the data receiver from the data sender. In this case, the target data is the audio frame data corresponding to the song or chat voice message, and the data sender is the audio source sender.

[0107] 203. Based on the first power-on duration and the power-on duration deviation, determine the second power-on duration of the data receiving end when the target data is sent.

[0108] The second power-on duration is the time elapsed from the moment the data receiver powers on until the moment the target data is sent.

[0109] Specifically, if Toffset represents the difference between the power-on time of the data receiver and the power-on time of the data sender, then the second power-on time can be obtained as follows:

[0110] Ts = Tnow + Toffset

[0111] Optionally, if Toffset represents the difference between the power-on time of the data sending end and the power-on time of the data receiving end, then the second power-on time can be obtained as follows:

[0112] Ts = Tnow - Toffset

[0113] Tnow represents the first boot duration.

[0114] Therefore, the second power-on duration Ts represents the time elapsed since the data receiver started transmitting the target data.

[0115] In some optional embodiments, the target data can be audio frame data. Correspondingly, the data sender is the audio source sender, which can send audio frame data to the data receiver. The data receiver is the audio playback end, which can receive and play the audio frame data sent by the audio source sender. For example, a user can select to send a segment of audio to the data receiver from the data sender. In this case, the target data is the audio frame data corresponding to this audio segment, the data sender is the audio source sender, and the data receiver is the audio playback end.

[0116] It is understood that, in this embodiment of the invention, the power-on duration deviation can be updated periodically or irregularly while the data receiving end and the data sending end maintain a connection. When calculating the second power-on duration, the latest power-on duration deviation is generally used at the time of calculation.

[0117] For example, such as Figure 3As shown, a thread can be set in the data receiving end to repeatedly execute the step of calculating the boot time deviation. It can be executed once every 10 seconds until the data receiving end disconnects from the data sending end.

[0118] To conserve thread processing resources on both the data sender and receiver, the data receiver can generate a first thread termination flag and send it to the data sender when it needs to disconnect from the data sender. Alternatively, the first thread termination flag can be generated at a preset time.

[0119] For example, technicians can set the data receiver to generate the first thread termination marker 10 minutes after the data sender and receiver establish a connection; or, technicians can set the data receiver to generate the first thread termination marker 10 times after the data sender and receiver calculate the boot time deviation.

[0120] In this embodiment of the invention, the first thread termination flag can instruct the data sending end and the data receiving end to terminate the thread used to calculate the boot time deviation.

[0121] 204. Determine the third power-on duration of the data receiving end when receiving target data, and calculate the transmission time of the target data based on the second power-on duration and the third power-on duration.

[0122] The third power-on duration is the time elapsed from the moment the data receiver powers on until it receives the target data.

[0123] Specifically, transmission time is the duration it takes for the target data to be transmitted from the data sender to the data receiver.

[0124] Optionally, if Toffset represents the difference between the power-on time of the data receiver and the power-on time of the data sender, then the transmission time Ta can be calculated using the following formula:

[0125] Ta = T0 - (Tnow + Toffset)

[0126] Optionally, if Toffset represents the difference between the power-on time of the data sender and the power-on time of the data receiver, then the transmission time Ta can be calculated using the following formula:

[0127] Ta = T0 - (Tnow - Toffset)

[0128] T0 is the third power-on duration.

[0129] In this embodiment of the invention, the thread that calculates the transmission time and the thread that calculates the boot time deviation can be two different threads.

[0130] like Figure 4As shown, both the data receiving end and the data sending end can include a discovery and connection unit, a data transmission unit, and a communication module selection unit. The discovery and connection module is primarily responsible for discovering and securely connecting to the wireless speaker. During the initial discovery, security authentication for different short-range communication methods (such as Wi-Fi and Bluetooth) is performed and paired, allowing the communication module selection unit to automatically and seamlessly switch between communication modules.

[0131] The data transmission unit is used for data transmission between the data sending end and the data receiving end.

[0132] Taking audio data as an example, the data transmission module is the audio transmission module. The audio transmission module primarily transmits the audio frame data from the audio source to the audio playback end via the first short-range communication module. The audio source acquires and losslessly encodes the sound, then transmits it to the audio playback end via a socket. Upon receiving the sound, the audio playback end performs decoding, error correction, buffering, and anti-jitter algorithms before playing it out.

[0133] The transmitted audio frame format can be: audio time header (64 bits, 8 bytes) + audio frame data. The audio time header is filled with the number of milliseconds Tnow that the audio source sending device has been powered on since the audio frame was generated. This data is used for the delay calculation of each audio frame in the communication module's optimization unit.

[0134] 205. If the transmission time exceeds the preset transmission time threshold, a connection is established with the data sender through the second short-range communication module, and data is transmitted through the second short-range communication module.

[0135] The second short-range communication module is another module in the data receiver that can realize short-range communication function.

[0136] It should be noted that the latency of the short-range communication method corresponding to the first short-range communication module can be less than the latency of the corresponding short-range communication method of the second short-range communication module under normal transmission conditions. For example, the first short-range communication module can be a WiFi communication module, and the second short-range communication module can be a Bluetooth communication module.

[0137] Specifically, the transmission time threshold can be set by technicians or users based on actual application requirements. For example, it can be determined based on the delay difference between the first short-range communication module and the second short-range communication module.

[0138] For example, the first short-range communication module can be a WiFi communication module, and the second short-range communication module can be a Bluetooth communication module. In this case, the transmission latency threshold Tbt can be set as the delay time for the Bluetooth communication module to transmit audio. It is understandable that different devices may have different latency values ​​for their Bluetooth communication modules. Depending on the device, the transmission latency threshold Tbt can be set between 120 and 200 milliseconds.

[0139] In practical applications, regardless of whether a second short-range communication module is used for data transmission, the data receiving end and the data sending end always maintain data transmission and reception through the first short-range communication module in order to calculate the transmission time of the first short-range communication module and to achieve faster seamless switching. That is, the step "If the transmission time exceeds a preset transmission time threshold, establish a connection with the data sending end through the second short-range communication module and transmit data through the second short-range communication module" can specifically include:

[0140] If the transmission time exceeds the preset transmission time threshold, maintain the connection between the first short-range communication module and the data sender.

[0141] A connection is established with the data sender through the second short-range communication module, and data is transmitted through the second short-range communication module.

[0142] In other words, regardless of which short-range communication module is used for data transmission, the first short-range communication module will maintain a continuous connection with the data sender.

[0143] Accordingly, the communication module switching method provided in this embodiment of the invention may further include:

[0144] The transmission time is calculated by the first short-range communication module that maintains a connection with the data sender, and the new transmission time of the first short-range communication module when transmitting data is determined.

[0145] If the new transmission time is not greater than the switching time threshold, disconnect the connection between the second short-range communication module and the data sender, and continue data transmission through the first short-range communication module.

[0146] The switching time threshold can be set by technicians or users based on actual application requirements. For example, it can be determined based on the delay difference between the first short-range communication module and the second short-range communication module.

[0147] For example, the first short-range communication module can be a WiFi communication module, and the second short-range communication module can be a Bluetooth communication module. In this case, the switching time threshold can be set to the delay time of the WiFi communication module transmitting audio.

[0148] For example, such as Figure 5 As shown, Ta can be monitored continuously for 10 seconds. If Ta is less than 80 (the switching time threshold) each time, or if the average value calculated by sliding filter (the average value after removing the fluctuations of the maximum and minimum values) is less than 80, then the system will switch back to using the audio data transmitted by the first short-range communication module, thereby ensuring that the latency is less than 80 milliseconds when returning to the first short-range communication module.

[0149] Optionally, when determining the new transmission time of the first short-range communication module during data transmission, the new transmission time can be calculated by transmitting the target data currently being transmitted by the second short-range communication module through the first short-range communication module, or by transmitting specific test data or empty data packets through the first short-range communication module.

[0150] In some optional embodiments, to avoid the impact of transmission time calculation errors and to prevent frequent switching of the short-range communication module from burdening the data receiver and data sender, the step "If the transmission time is greater than a preset transmission time threshold, establish a connection with the data sender through the second short-range communication module and perform data transmission through the second short-range communication module" may specifically include:

[0151] If the transmission time is greater than the preset transmission time threshold, the reference transmission time of each time the data sent by the data sending end is received through the first short-range communication module within the preset time after the target data is transmitted is counted.

[0152] If the transmission time for each reference is greater than the transmission time threshold, a connection is established with the data sender through the second short-range communication module, and data is transmitted through the second short-range communication module.

[0153] For example, it could monitor Ta continuously for 5 seconds. If Ta is greater than Tbt each time, then switch to the second short-range communication module to transmit audio. At this time, notify the data sender to open the second short-range communication module to connect with the data receiver and transmit data.

[0154] In some alternative embodiments, the step "if the transmission time is greater than a preset transmission time threshold, establish a connection with the data sender through the second short-range communication module, and perform data transmission through the second short-range communication module" may specifically include:

[0155] If the transmission time is greater than the preset transmission time threshold, the reference transmission time of each time the data sent by the data sending end is received through the first short-range communication module within the preset time after the target data is transmitted is counted.

[0156] Calculate the average transmission time corresponding to the reference transmission time;

[0157] If the average transmission time exceeds the transmission time threshold, a connection is established with the data sender through the second short-range communication module, and data transmission is performed through the second short-range communication module.

[0158] For example, it could involve continuously monitoring Ta for 5 seconds. If the average value of the transmission time for each reference (the average after removing fluctuations of the maximum and minimum values) calculated using sliding filtering, Ta, is greater than Tbt, then the system switches to the second short-range communication module to transmit audio. At this point, the data sender is notified to open the second short-range communication module to connect with the data receiver and transmit data.

[0159] Optionally, to enhance the user's audiovisual experience, such as Figure 5 As shown, during short-range communication module switching, audio fusion needs to be performed on both the pre- and post-switching audio modules before outputting the new audio. The communication module switching method provided in this embodiment of the invention may further include:

[0160] Based on the first audio frame data received when transmitting audio data through the first short-range communication module, and the second audio frame data received when switching from the first short-range communication module to the second short-range communication module, the difference audio frame between the second audio frame data and the first audio frame data is determined;

[0161] Based on the difference audio frames, speed-changing without pitch-changing processing is performed to obtain the processed difference audio frames;

[0162] Audio is played based on the processed difference audio frames and the second audio frame data.

[0163] During switching, the first audio frame data received during audio data transmission through the first short-range communication module is compared with the second audio frame data received during audio data transmission through the second short-range communication module. The frames that are the same but different are identified, and the frames that are different are accelerated and played back while maintaining the same pitch, thus enabling seamless switching.

[0164] Through the embodiments of the present invention, users will not perceive any stuttering or audio dropouts. If the second short-range communication module (e.g., Bluetooth) switches back to the first short-range communication module (e.g., WiFi), a data packet is sent to notify the audio source to turn off Bluetooth after the audio fusion is completed.

[0165] Specifically, variable speed without pitch processing can be achieved by using methods such as Synchronized Overlap-Add (SOLA), Synchronized Overlap-Add and Fixed Synthesis (SOLA-FS), resampling, interpolation and decimation of the signal spectrum to process audio frame data.

[0166] It should be noted that the data receiving end can generate a second thread termination flag and send it to the data sending end when it needs to disconnect from the data sending end.

[0167] In this embodiment of the invention, the second thread termination flag may be the same as or different from the first thread termination flag. The second thread termination flag can instruct the data sender and data receiver to terminate the thread used for data transmission.

[0168] As can be seen from the above, the embodiments of the present invention can obtain the power-on duration deviation between the data sending end and the data receiving end, and receive the target data sent by the data sending end through a first short-range communication module that establishes a connection with the data sending end. The target data includes the first power-on duration of the data sending end when the target data is sent. Based on the first power-on duration and the power-on duration deviation, the second power-on duration of the data receiving end when the target data is sent is determined, and the third power-on duration of the data receiving end when receiving the target data is determined. Based on the second power-on duration and the third power-on duration, the transmission time of the target data is calculated. If the transmission time is greater than a preset transmission time threshold, the method is used to... The second short-range communication module establishes a connection with the data sending end and performs data transmission through the second short-range communication module. In this embodiment of the invention, the transmission time of the target data is determined based on the power-on duration of the data sending end and the power-on duration of the data receiving end corresponding to the transmission target data. The short-range communication module communicating with the data sending end in the data receiving end is dynamically switched according to the transmission time. Therefore, automatic switching of different short-range communication methods can be realized without manual settings by the user, improving the user's data transmission experience and enabling low-latency, high-quality data transmission in various scenarios.

[0169] To better implement the above methods, this embodiment of the invention also provides a communication module switching device.

Specifically, in one embodiment, input unit 803 may include a touch-sensitive surface and other input devices. A touch-sensitive surface, also known as a touch display or touchpad, can collect user touch operations on or near it (e.g., user operations using fingers, styluses, or any suitable object or accessory on or near the touch-sensitive surface) and drive corresponding connection devices according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. The touch detection device detects the user's touch orientation and the signal generated by the touch operation, transmitting the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to the processor 808, and can receive and execute commands from the processor 808.

Conversely, the microphone converts collected sound signals into electrical signals, which are then received by audio circuitry 806, converted back into audio data, and processed by processor 808. The processed data is then transmitted via RF circuitry 801 to, for example, another electronic device, or output to memory 802 for further processing. Audio circuitry 806 may also include an earphone jack to facilitate communication between peripheral headphones and the electronic device.
