Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
The technical scheme of the application is suitable for a Bluetooth communication scene, in particular for an application scene that a master Bluetooth device and a slave Bluetooth device communicate by using a low-power-consumption synchronous data stream connection in the Bluetooth communication scene. The main Bluetooth device searches surrounding Bluetooth devices and selects Bluetooth devices to be connected for pairing connection; a slave bluetooth device refers to a device waiting to be searched for a connection by a master bluetooth device in a bluetooth communication scenario. Specifically, the main bluetooth device may be a mobile phone, a notebook computer, etc.; the slave bluetooth device may be an earphone, an intelligent sound, etc., and the present application is not limited. It should be appreciated that a bluetooth device may either initiate a communication connection as a master bluetooth device or receive a communication connection as a slave bluetooth device; one bluetooth device can also serve as a master bluetooth device and a slave bluetooth device at the same time.
As a possible implementation manner, in the synchronous data stream connection mode of the low-power consumption Bluetooth, the master Bluetooth device and the slave Bluetooth device perform two-way communication and synchronously process data, so that the problem that the Bluetooth left and right earphone devices are not synchronous can be solved. A single connected synchronization stream provides point-to-point synchronization communication and multiple connected synchronization streams may be processed in synchronization as shown in fig. 1. A connected synchronization group may comprise a plurality of connected synchronization streams, all connected synchronization streams within the synchronization group jointly adhering to the same communication link parameter setting. The data synchronization process can be achieved by configuring the same communication link parameters for all connected synchronization streams.
In one possible implementation, within the same connected synchronization group, the occurrence interval of each event for each connected synchronization stream, referred to as an event time interval (sub-interval), is divided into one or more sub-events, each event may refer to a communication set of a master bluetooth device and all slave bluetooth devices, and a sub-event may refer to a single communication procedure of the master bluetooth device and a single slave bluetooth device. The interval between two adjacent connected synchronization group anchors, called ISO-interval (ISO-interval), may be specified in the time range of 5ms to 4s. In the sub-event of the bluetooth low energy synchronous data stream connection transmission mode, the transmission and reply of the master bluetooth device and the slave bluetooth device may be as shown in fig. 2. In the embodiment of the application, each connected synchronous stream link of the slave Bluetooth device can be allocated with a unique identifier, and the communication period can be determined according to the ISO time interval.
Within the same connected synchronization group, the communication status of different connected synchronization flows may be different, for example, a slave bluetooth device further away from the master bluetooth device may receive a data packet with a worse result than a slave bluetooth device closer to the master bluetooth device, or a slave bluetooth device with an interference source in the surroundings may receive a data packet with a worse result than a slave bluetooth device without an interference source in the surroundings. Since the communication link parameters of each connected synchronization flow are the same in the connected synchronization group, if the communication link parameters are modified, the communication reliability between the devices may not be improved, but normal communication between the devices may be affected.
In view of this, the present application proposes a communication link configuration scheme that can improve the reliability of communication between devices by configuring the number of communication links without modifying the parameters of the communication links. The technical solution of the present application may be applied to the bluetooth system shown in fig. 3, and as shown in fig. 3, the bluetooth system 30 may include a master bluetooth device 301 and a slave bluetooth device 302, where the master bluetooth device 301 may simultaneously communicate with a plurality of slave bluetooth devices 302, and establish a low-power synchronous data stream connection with the plurality of slave bluetooth devices 302.
In one possible implementation, the slave bluetooth device 302 and the master bluetooth device 301 may establish a low energy synchronous data stream connection by: firstly, it is ensured that bluetooth of the master bluetooth device 301 and bluetooth of the slave bluetooth device 302 are both opened, then, in bluetooth setting of the master bluetooth device 301, a search function of the device is started to search for nearby devices capable of supporting low-power synchronous data stream connection, after searching, the master bluetooth device 301 lists nearby devices capable of establishing low-power synchronous data stream connection, a user can select a device to be connected from the list and pair with the selected device, once pairing is successful, the master bluetooth device 301 establishes low-power bluetooth connection with the slave bluetooth device 302 first, and on the basis of establishing a low-power bluetooth connection link, the master bluetooth device 301 initiates a low-power synchronous data stream connection establishment request to the slave bluetooth device 302, and after configuring relevant communication parameters, the establishment of the low-power synchronous data stream connection is completed.
In one possible manner, the master bluetooth device 301 may transfer data between devices after establishing a low power synchronized data stream connection with the slave bluetooth device 302. This may be bi-directional, with information being sent and received between the devices. When the data transfer is complete or the low power isochronous data stream connection is no longer needed, the master bluetooth device 301 or the slave bluetooth device 302 may choose to disconnect the low power isochronous data stream connection. This may be performed in the device settings or the connection between the devices may be automatically broken after a period of inactivity.
It should be noted that the exact steps of establishing a synchronous data stream connection with low power consumption may vary from device to device and from operating system to operating system. The above methods provide a general overview, and the specific methods may vary somewhat from device to device and operating system to operating system, as the application is not limited in this regard.
In a possible implementation manner, as shown in fig. 4, the bluetooth system may be a mobile phone, where the master bluetooth device shown in fig. 4 is a slave bluetooth device, and the slave bluetooth devices are respectively E1, E2 and E3, where it can be seen that the slave bluetooth device is located in different communication environments, where the slave bluetooth device E1 is closer to the master bluetooth device, where the slave bluetooth device E3 is farther from the master bluetooth device, where an interference source exists near the slave bluetooth device E2, where all of the slave bluetooth devices E1, E2 and E3 may establish a low-power synchronous data stream connection with the master bluetooth device.
The following describes the technical solution of the present application in detail with reference to the systems shown in fig. 3 and 4.
Referring to fig. 5, fig. 5 is a schematic flow chart of a communication link configuration method according to an embodiment of the present application, where the communication link configuration method may be applied to a bluetooth system, and the bluetooth system may be as shown in fig. 3 and fig. 4. As shown in fig. 5, the communication link configuration method includes the steps of:
s501, a master bluetooth device determines a communication environment parameter between the master bluetooth device and a slave bluetooth device.
Optionally, the communication environment parameter refers to a parameter for evaluating communication quality between the master bluetooth device and the slave bluetooth device, and the communication environment parameter may include multi-dimensional environment data, such as a distance value between devices, signal strength, and the like.
In one possible embodiment, the determining the communication environment parameter between the master bluetooth device and the slave bluetooth device includes: receiving a first communication data packet of the slave Bluetooth device; and determining communication environment parameters between the master Bluetooth device and the slave Bluetooth device according to the first communication data packet.
In one possible embodiment, the first communication data packet includes: and receiving any one or more of signal strength indication, link quality and packet loss rate in a preset time range.
For example, in the process of establishing a low-power-consumption synchronous data stream connection with the slave bluetooth device, the master bluetooth device may send a first communication data packet to the master bluetooth device, where the first communication data packet may include parameters such as a received signal strength indication, a link quality, a packet loss rate within a preset time range, and the like, and the master bluetooth device receives the first communication data packet, comprehensively evaluates a current communication environment according to the parameters in the first communication data packet, and determines a communication environment parameter between the master bluetooth device and the slave bluetooth device.
The received signal strength indicator (Received Signal Strength Indicator, RSSI) is related to the signal strength, and reflects the attenuation degree of the signal, where the unit is dBm, the received signal strength indicator is a negative value, and a larger value indicates a stronger signal, and may indicate a better communication quality, and a corresponding communication environment parameter may be higher. In general, the larger the received signal strength indication is, the less susceptible to interference, and ideally the signal will not be attenuated when the received signal strength indication is 0.
The Link Quality (LQ) can be used to evaluate the quality of the current received signal, the value range is 0-255, and is generally related to the frequency of signal modulation, and the better the link quality is, the greater the link quality is, the higher the corresponding communication environment parameter can be represented, otherwise, the smaller the communication quality is, and the manufacturer can customize the measurement standard of the link quality value and map the measurement standard into the value range.
The packet loss rate in the preset time range is the transmission times of repeated packets in all transmission packets of the main Bluetooth device in a certain time, and generally, the higher the packet loss rate is, the worse the communication quality is represented, the lower the corresponding communication environment parameter can be, otherwise, the lower the packet loss rate is, and the higher the corresponding communication environment parameter can be.
In a possible implementation, the determining the communication environment parameter between the master bluetooth device and the slave bluetooth device may further be: transmitting a second communication data packet to the slave bluetooth device; receiving a response packet of the slave Bluetooth device for the second communication data packet; and determining the communication environment parameters of the master Bluetooth device and the slave Bluetooth device according to the response packet.
In one possible embodiment, the second communication data packet includes: any one or more of a received signal strength indication, a link quality, and an error rate within a preset time range.
For example, in the process of establishing a low-power-consumption synchronous data stream connection with the slave bluetooth device, the master bluetooth device may send a second communication data packet to the slave bluetooth device, where the second communication data packet may include parameters such as a received signal strength indication, a link quality, an error rate within a preset time range, and the like, the slave bluetooth device may evaluate a current communication environment according to the parameters in the second communication packet, and send a response packet to the master bluetooth device for the second communication data packet, and the slave bluetooth device may determine a communication environment parameter according to the response packet, so as to perform further configuration of the number of communication links.
Wherein the error rate is the ratio of the number of errors to the total number of transmitted codes, and referring to the error rate of each packet or the average error rate of a plurality of packets, in bluetooth, a forward error correction (Forward Error Correction, FEC) function is provided, including 1/3FEC, which is a repetition code, each information bit is repeatedly transmitted three times, and a slave device checks whether three values are consistent, the latter is a hamming code, and 10 information bits generate 15 bits after polynomial operation, so that all odd-numbered bits can be corrected and all even-numbered bits can be detected. The error rate and/or the average error rate may be counted by FEC.
In a possible implementation manner, in order to accurately determine the communication environment parameter, a professional testing tool and equipment can be used for performing auxiliary tests, such as a signal intensity meter, a spectrum analyzer and the like, so that the progress of data measurement can be further improved, and the accuracy of a data result can be improved.
S502, the main Bluetooth equipment configures the number of connected synchronous stream communication links according to the communication environment parameters.
For example, the master bluetooth device may set a different number of communication links for each connected synchronization stream according to the communication environment parameters. As shown in fig. 4, one connected synchronous stream communication link may be configured between the slave bluetooth device E1 and the master bluetooth device, two connected synchronous stream communication links may be configured between the slave bluetooth device E2 and the master bluetooth device, and three connected synchronous stream communication links may be configured between the slave bluetooth device E3 and the master bluetooth device. Because the slave bluetooth devices E1, E2 and E3 belong to the same connected synchronization group, no matter how many communication links are, the data are synchronous, and the data are not affected by the number of links, and the communication reliability of the slave bluetooth device with poor communication environment is correspondingly improved due to the increase of the communication links with the master bluetooth device, and meanwhile, the communication states of other slave bluetooth devices are not affected.
In a possible embodiment, when the number of connected synchronous stream communication links is greater than or equal to two, the communication link configuration method further includes: setting a corresponding connected synchronous flow identification for each connected synchronous flow communication link configured.
It should be noted that the connected synchronous stream identification (CIS-ID) is used to uniquely identify the corresponding connected synchronous stream communication link. When data transmission is performed, the master bluetooth device may sequentially transmit data according to the sequence of the connected synchronous stream identifiers.
In a possible embodiment, the connected synchronization flow identification is a non-continuous identification.
For example, when the same slave bluetooth device has multiple connected synchronous stream communication links with the master bluetooth device, the connected synchronous stream identifiers of the multiple connected synchronous stream communication links may preferably be a non-continuous identifier, i.e., with the connected synchronous stream identifiers in-between for communication with other slave bluetooth devices. For example, in fig. 4, the slave bluetooth device E1 has one connected synchronous stream communication link, the corresponding connected synchronous stream is identified as 1, the slave bluetooth device E2 has two connected synchronous stream communication links, the corresponding connected synchronous stream is identified as 2 and 4, and the slave bluetooth device E3 has three connected synchronous stream communication links, and the corresponding connected synchronous stream is identified as 3, 5 and 6.
In a possible implementation manner, the master bluetooth device may perform communication with a plurality of the slave bluetooth devices according to a time division multiplexing manner, and sequentially transmit the connected synchronous stream identifiers of the communication links according to the connected synchronous stream identifiers of the communication links, as shown in fig. 6, stagger the connected synchronous stream identifiers of the connected synchronous stream communication links of the same slave bluetooth device, if the slave bluetooth device E2 has corresponding connected synchronous stream identifiers of 2 and 4, and the slave bluetooth device E3 has corresponding connected synchronous stream identifiers of 3, 5 and 6, and during data transmission, the master bluetooth device may transmit according to the label sequence of the identifiers, so as to prevent excessive interference at a certain moment from causing data receiving failure, which is beneficial to further improving the reliability of communication.
In a possible implementation, the slave bluetooth device may preset itself to support communication through multiple connected synchronous stream channels to ensure efficient transmission of data.
By implementing the embodiment of the application, the master Bluetooth device determines the communication environment parameters of the master Bluetooth device and the slave Bluetooth device and sets the number of connected synchronous stream communication links according to the communication environment parameters, so that the communication quality of the slave Bluetooth device with poor communication environment can be improved by configuring more communication links. Because the number of communication links in the same connected synchronization group does not influence the synchronization of data, the communication link number is increased, and the communication reliability between the master Bluetooth device and the slave Bluetooth device is correspondingly improved.
