Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a few of the embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without any creative effort belong to the protection scope of the embodiments of the present application.

In the current bluetooth system for communication, one link of a receiving end of bluetooth usually carries a plurality of logical links of an opposite bluetooth end, and when data transmission is performed, the plurality of logical links multiplex the same physical frequency hopping link in a time-sharing manner, so that different signals are transmitted in different time periods of the same physical frequency hopping link to perform multiplex transmission.

However, in the prior art, when performing multiplexing, the bluetooth system can only process the data transmitted in each path in turn. However, in a transmission scenario where there are many transmission nodes and the requirement for the real-time performance of bluetooth transmission is high, for example, when audio data is transmitted, the time for processing in the current manner is long. For example, in the application of a wireless MIC (Microphone), a plurality of MIC terminals are generally provided at present, a receiving terminal is linked through bluetooth, and then the receiving terminal is connected to a mobile phone or other recording equipment for recording through a USB interface or other wired interfaces or wireless connection manners. If there are many wireless MIC devices, the receiving end of bluetooth needs to receive all data of the MIC in the same time period before performing the integration process and outputting the data. However, the bluetooth system is a Time Division Multiple Access (TDMA) Time division system, and only a link of one wireless MIC terminal can be connected at the same Time to independently receive or transmit data to one wireless MIC terminal, so that at each interactive Time, after the first wireless MIC terminal is completed by Time division reception or transmission, the second wireless MIC terminal can be served, i.e., processed in a serial manner.

In this case, the more wireless MIC terminals exist, the greater the bluetooth transmission pressure for the receiving terminal, and the more wireless MIC terminals connected to the receiving terminal, the longer the processing time, which results in a larger delay when bluetooth supports multiplexing, but the current wireless MIC has a higher demand for low delay, for example, the delay is controlled within 15 ms. Therefore, the delay condition during bluetooth transmission is serious at present, which results in low data processing efficiency, transmission efficiency and communication efficiency during bluetooth communication, and cannot meet the requirements of users.

In order to solve the above problem, an embodiment of the present application provides a data processing method, which is applied to a terminal device, where the terminal device may be an electronic device with a logic computation function, such as a server, a Personal Computer (PC), an earphone, a tablet Computer, a smart phone, and a Personal Digital Assistant (PDA).

To facilitate understanding of the present embodiment, a detailed description is first given of a terminal device and an operating environment for executing a data processing method disclosed in the embodiments of the present application.

Referring to fig. 1, fig. 1 is a schematic diagram of an operating environment of a data processing method according to an embodiment of the present application, where the operating environment includes the following interactive devices: the terminal device 100 is connected with the first device 110 and the second device 120 through Bluetooth respectively to carry out data communication or interaction.

It is noted that the first device 110 and the second device 120 may be the same type of associated devices, or may be different types of associated devices, such as devices associated with multiple wireless MIC terminals or earphone terminals. In the embodiment provided by the present application, only one implementation that the terminal device 100 is connected to two external devices is shown, the terminal device 100 may also be connected to a greater number of external devices, and the method for processing data of multiple devices is similar to that for processing data of two devices, and is not described again.

Alternatively, the terminal device 100 may be used as a receiving end of bluetooth, and may be connected to other devices for processing data through a wired connection manner or a wireless connection manner such as a USB interface, or the terminal device 100 may directly process data.

Referring to fig. 2, fig. 2 is a schematic flow chart of a data processing method according to an embodiment of the present application, where the method includes: steps S200-S300.

Step S200, allocating a first link corresponding to the first device connected to the terminal device to a first communication channel for processing.

The first link is a logical link established when the first device and the terminal device are in Bluetooth connection, and corresponding data are transmitted through a control and adaptive protocol.

Step S300, allocating a second link corresponding to a second device connected to the terminal device to a second communication channel for processing.

The second link is also a logical link established when the second device is in bluetooth connection with the terminal device, and transmits corresponding data through a control and adaptive protocol.

Optionally, the first device and the second device are external devices that establish a bluetooth connection with the terminal device, for example, multiple devices of the same type or different types, such as a wireless MIC device and an earphone device. And the external device may further include a larger number of devices such as a third device and a fourth device, and when the external device establishes a bluetooth connection with the terminal device, the terminal device is used as a Master device (Master device), and one or more external devices are used as Slave devices (Slave devices), and the connection is established through the processes of page and role switch.

Optionally, when the plurality of external devices are connected to the terminal device, the plurality of external devices may be further sorted according to the time when the external devices establish the bluetooth connection with the terminal device, so that the links of the respective devices are correspondingly allocated according to the time when the connection is established.

It is worth mentioning that a plurality of communication channels extending may be included in the terminal device. For example, the extension mode may be to establish a plurality of communication channels corresponding to the structures in the same communication chip during design and production, or to connect a plurality of communication chips, where each communication chip may include one communication channel, so that the plurality of communication channels have relevance. And, in the case of expanding to obtain a plurality of communication channels, delay condition in data processing is reduced by setting a clock source. The multiple communication channels in the same communication chip can be respectively connected with the same clock source in the chip, and the multiple communication channels in different communication chips can also be connected with an external clock source, so that the communication channels sharing the clock source can be obtained, the time in the multiple communication channels is synchronized, and subsequent scheduling is facilitated.

Illustratively, the clock source may be a hardware clock source or Timer such as a HW Timer or a Trans Queue.

Optionally, in the terminal device, the software layer may be modified correspondingly according to the extension of the hardware structure, and the processor is provided with a Link Manager (LM) and a Link Driver (LD) for each communication channel, and a Scheduler (Scheduler) for scheduling a process of connecting and processing the plurality of communication channels and links. The link managers corresponding to each communication channel respectively distribute the links of the external equipment acquired from the terminal equipment to the communication channels corresponding to the links, so that the links of the equipment can be distributed to different communication channels for processing, but not all the links are processed in a serial mode in one communication channel, the processing time is reduced, larger data volume in the equipment can be processed synchronously, the processing efficiency of the terminal equipment on the links is improved, the transmission efficiency of data between the terminal equipment and the external equipment is improved, the bandwidth during Bluetooth transmission is expanded, and the requirement of various external equipment on low delay during transmission is met.

In the embodiment shown in fig. 2, the delay condition during bluetooth transmission is effectively reduced, and the processing efficiency and transmission efficiency of data in the bluetooth system are improved.

Optionally, the first communication channel may include: referring to fig. 3, fig. 3 is a detailed flowchart of a step S200 according to an embodiment of the present application, where the step S200 may further include: steps S210-S230.

Step S210, when the first device is connected to the terminal device, allocating a first link corresponding to the first device to the first address in the first communication channel based on the first interface and the first antenna, so that the first link is connected to the first address.

The first link of the first device is allocated to the first communication channel by the link manager corresponding to the first communication channel, and the first antenna in the first communication channel can receive the first link and place the first link into the first interface for multiplexing, so that the first link is allocated to the corresponding first address for processing.

Step S220, acquiring an interval period of the first device.

The first device may be an external device that establishes a bluetooth connection with the terminal device first in the time domain, or may be an external device that is designated for performing time alignment. After the first device is connected with the terminal device through the Bluetooth, the link manager can acquire the next interactive time in the first device according to the corresponding interactive communication mode, and determine the time interval between the current time and the next interactive time between the first device and the terminal device by combining the current time.

Step S230, determining a first transceiving timing of the first link according to the interval period.

When the terminal device is connected with the first device through bluetooth, the terminal device may receive data in the first device and send corresponding data to the first device, and the bluetooth is a frequency hopping system, and frequencies in each time sequence are not necessarily the same, so that, in order to further reduce transmission efficiency during bluetooth communication, a first transceiving time sequence occupied by the first address when the terminal device interacts with the first device to receive and send data in the first link may be determined according to the determined interval time period, so as to symmetrically and isochronously transceive the data.

Optionally, the first receiving period and the first transmitting period of the first link are allocated according to the interval period, and the first receiving period and the first transmitting period are used as the first transceiving timing of the first link. In order to perform symmetric and equal-field transceiving, the first receiving period and the second receiving period may be set to the same period, for example, both may be set to 2 slots. The Bluetooth Connection can be similar to an SCO (Synchronous Connection ordered, which is mainly used for transmitting data communication Connection with high time requirement), so that the terminal equipment can regularly transmit and receive with the first equipment at corresponding time, the delay condition during the Bluetooth communication is further reduced, and the real-time performance and the transmission efficiency during the Bluetooth communication of the terminal equipment are improved.

In the embodiment shown in fig. 3, an interval period between the current time and the preset next interaction time in the first device may be obtained based on the connection, so as to determine the first transceiving timing sequence occupied by the first link in the first address according to the interval period, thereby improving the effect of reducing the delay.

Optionally, the second communication channel may include: referring to fig. 4, fig. 4 is a detailed flowchart of a step S300 according to an embodiment of the present disclosure, where the step S300 may further include: steps S310-S330.

Step S310, when the second device is connected to the terminal device, allocating a second link corresponding to the second device to the second address in the second communication channel based on the second interface and the second antenna, so that the second link connects to the second address.

And allocating a second link of the second device to a second communication channel by a link manager corresponding to the second communication channel, wherein a second antenna in the second communication channel can receive the second link and place the second link into a second interface for multiplexing so as to allocate the second link to a corresponding second address for processing.

Step S320, performing clock alignment on the second device according to the acquired interval period of the first device.

In the present application, the first device is used as a reference device, the interval time interval in the first device is used as a reference time interval when clocks are aligned, other devices may also be used as reference devices, the interval time interval corresponding to the other devices is used as a reference time interval when clocks are always aligned, and other cases are not described again. The scheduler may obtain an interval period of the first device obtained in the link manager corresponding to the first communication channel, and send the interval period to the link manager corresponding to the second communication channel, so as to align a time when the second device interacts with the terminal device with a time in the first device according to the shared clock source and the interval period, thereby enabling the first device and the second device to interact with the terminal device in a communication mode with the same time.

Optionally, since the interval period in the first device can be changed correspondingly according to the change of the communication mode, when the second communication channel performs clock alignment, the second communication channel can also perform corresponding alignment according to the acquired interval period, and when the communication mode of the reference device changes, the time alignment condition of the other device can be adjusted correspondingly.

Step S330, determining a second transceiving timing in the second link when the first transceiving timing is equal to the second transceiving timing according to the interval period.

When a plurality of external devices are connected with the terminal device through Bluetooth, synchronous processing of simultaneously receiving data and simultaneously sending data by the plurality of devices and the terminal device is realized, and communication modes of the plurality of devices can be further synchronized. The synchronization mode may be that on the basis of clock alignment, the scheduler and the link manager acquire a first transceiving timing in the first communication channel, so as to determine a second transceiving timing, which is occupied in the second communication channel and is equal to the first transceiving timing, according to the aligned interval period.

Optionally, a second receiving period and a second transmitting period of the second link are allocated according to the interval period, and the second receiving period and the second transmitting period are used as a second transceiving timing of the second link. The first receiving time interval and the first sending time interval are equal to the second receiving time interval and the second sending time interval in time domain, so the first transceiving time sequence and the second transceiving time sequence are equal time sequences. When the links of a plurality of devices are processed simultaneously by a plurality of communication channels, isochronous transmission and reception orders can be set for the plurality of links in the plurality of communication channels according to clock alignment, and isochronous and symmetric transmission and reception between the plurality of devices and the terminal device can be realized.

It should be noted that the first antenna and the second antenna may both be RF (Radio Frequency, video) antennas, the first interface and the second interface may both be PHY (Physical Layer) interfaces, and the first Address and the second Address may both be MAC (Media Access Control Address) addresses, such as local area network Address (LAN Address), MAC Address, Ethernet Address, and the like.

When a communication chip of a terminal device is manufactured, distances, angles, couplings, a manufacturing process and the like among a plurality of antennas all affect the isolation of a plurality of communication channels, and when the isolation is poor, the communication efficiency of the communication channels may be negatively affected. Therefore, the adverse effect brought by the antenna isolation can be reduced by adopting the clock alignment and synchronous transceiving modes, the bandwidth is optimized through scheduling, and even if the Bluetooth connection of a plurality of devices has a frequency hopping conflict condition, the Bluetooth communication efficiency of the plurality of devices cannot be greatly influenced.

In the embodiment shown in fig. 4, by time-aligning the transceiving timings of the multiple links, when the terminal device performs bluetooth communication with multiple external devices, symmetric transceiving for simultaneously receiving and simultaneously transmitting with the multiple external devices is realized, thereby further reducing the delay time during bluetooth communication.

Optionally, referring to fig. 5, fig. 5 is a schematic flow chart of another data processing method provided in the embodiment of the present application, where the method may further include: steps S410-S420.

Step S410, acquiring a first link number in the first communication channel and a second link number in the second communication channel.

When the number of external devices connected to the terminal device is large, a plurality of links are provided and need to be processed. When the terminal device receives a plurality of links to be processed, there may be a situation that the plurality of links are queued to be processed in a time-sharing manner in a plurality of communication channels in the terminal device. In order to improve the processing efficiency of the terminal device on a plurality of links, the number of links in each communication channel can be respectively counted through the corresponding link manager.

Step S420, determining an allocation channel of the link to be processed based on the first link quantity and the second link quantity.

When the number of the links is large, the processing pressure of the communication channel is large, and the processing efficiency is low. Therefore, the scheduler can compare the number of the links obtained by statistics, and allocate the link to be processed to the communication channel for processing by using the communication channel with the smaller number of links as the allocation channel of the current link to be processed through the corresponding link manager, so as to improve the overall efficiency of the terminal device in processing the link.

For example, when the number of the first links in the first communication channel is 10, and the number of the second links in the second communication channel is 5, the second communication channel may be preferentially used as the distribution channel of the links to be processed.

Alternatively, for some links which are processed by the specified channel, the links may not be allocated according to the number of the links, but may be directly allocated to the corresponding communication channel by the corresponding link manager for processing.

In the embodiment shown in fig. 5, the links to be processed are allocated to the communication channels with a smaller number of links according to the number of links, so that multiple links can be efficiently and reasonably allocated, the situation that too many links are allocated to the same communication channel for processing is effectively reduced, and the processing efficiency of each communication channel on the links is improved.

Optionally, referring to fig. 6, fig. 6 is a schematic flowchart of another data processing method provided in the embodiment of the present application, where the method may further include: steps S510-S540.

Step S510, obtain first data obtained in the first communication channel based on the first link processing, and second data obtained in the second communication channel based on the second link processing.

Since the first device and the second device are external multiple related slave devices, the data transmitted by the multiple devices to the terminal device via different links is multiple uplink data. Each link is processed in each communication channel, and a plurality of uplink data, such as audio data uploaded by a plurality of wireless MIC devices, can be obtained, and the processor can further obtain the plurality of uplink data to perform corresponding operations.

Step S520, processing according to the first data and the second data to obtain target data.

The processor can perform integration processing according to the plurality of uplink data and the downlink data of the terminal device to obtain target data for output. For example, audio data uploaded by a plurality of wireless MIC devices may be mixed to obtain mixed data for output.

Step S530, forwarding the target data to the first device based on the first communication channel.

Step S540, forwarding the target data to the second device based on the second communication channel.

In order to improve the sending efficiency of the target data, the target data can be forwarded to the corresponding external device in a downlink manner through each address in each communication channel, so that the occupied comprehensive bandwidth is further reduced.

In the embodiment shown in fig. 6, the data can be comprehensively processed and synchronously forwarded, so that the occupied comprehensive bandwidth is effectively reduced.

Referring to fig. 7, fig. 7 is a schematic structural diagram of a terminal device 100 according to an embodiment of the present disclosure, where the terminal device 100 may include a first communication channel 130, a second communication channel 140, and a clock source 150.
