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 simultaneously use an LE-CIS transmission mode and a BLE transmission mode to communicate 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 Bluetooth device can be an earphone, a smart sound, a mobile phone, a computer and the like, and the 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.

Before the master Bluetooth device and the slave Bluetooth device communicate by using the LE-CIS communication link, an LE-CIS transmission mode needs to be established, the LE-CIS transmission mode is established on the basis of the BLE transmission mode, and in short, the master Bluetooth device and the slave Bluetooth device establish the BLE transmission mode first and then further establish the LE-CIS transmission mode on the basis of the BLE transmission mode.

For example, as shown in fig. 1, an exemplary diagram of a synchronization process of a plurality of CIS streams is shown. The slave Bluetooth device comprises a left earphone device and a right earphone device, wherein the CIS stream of the left earphone device and the CIS stream of the right earphone device form a synchronous connection group (Connected Isochronous Groups, CIG), and the CIS streams in the same synchronous connection group have the same ISO time interval so as to ensure that the CIS streams of the left earphone device and the CIS stream of the right earphone device in the same group are synchronous in Bluetooth data. Each CIS stream has a schedule of transmit and receive time slots, referred to as events and sub-events.

For example, as shown in fig. 2, a schematic diagram of data transmission applied to a synchronous connection set is shown. Event X and event x+1 in fig. 2 belong to the same synchronous connection group, each event is divided into one or more sub-events, and the time period between the start of transmission of bluetooth data in each sub-event and the start of transmission of bluetooth data in the next sub-event is called a sub-event time interval (sub-interval). The ISO interval (ISO-interval) refers to a time period between a start transmission time of bluetooth data in event X of one synchronous connection group and a start transmission time of bluetooth data in the next event x+1, which may be specified to be 5ms to 4s.

In one possible embodiment, as described above, the master bluetooth device and the slave bluetooth device also maintain a BLE transmission mode corresponding to the CIS transmission mode, which can exchange data between equal time intervals, referred to as Connection intervals (Connection interval), each data exchange being referred to as a Connection Event through which data transmission and reception are completed, as shown in fig. 3. Outside of the connection event, both the master bluetooth device and the slave bluetooth device are in a dormant state.

When two transmission modes of LE-CIS and BLE exist in a Bluetooth device at the same time, when bandwidth is allocated, communication time slots of LE-CIS and BLE are required to be respectively set on a time axis according to fixed time intervals and do not affect each other. However, in the CIS event of the LE-CIS, the number of times of sending a data packet does not exceed NSE times at most, and if the number of new data packets of the CIS is equal to 1, the data packet is successfully received in the first sub-event, and there is no communication interaction in the remaining NSE-1 sub-events, so that the bandwidth of the part of events is wasted.

In view of the above, the present application provides an event configuration method, apparatus, device, system and storage medium, which can effectively improve the bandwidth utilization. The technical solution of the present application may be applied to a bluetooth system shown in fig. 4, and as shown in fig. 4, the bluetooth system 40 may include a master bluetooth device 401 and a slave bluetooth device 402, where the master bluetooth device 401 may simultaneously communicate with a plurality of slave bluetooth devices 402, and establish LE-CIS transmission modes with the plurality of slave bluetooth devices 402.

In some possible embodiments, the master bluetooth device 401 and the slave bluetooth device 402 need to maintain BLE transmission mode with the slave bluetooth device 402 while establishing LE-CIS transmission mode.

Based on the system shown in fig. 4, the following specifically describes the technical solution of the present application.

Referring to fig. 5, fig. 5 is a flowchart of an event configuration method according to an embodiment of the present application. As shown in fig. 5, the method can be applied to a master bluetooth device that establishes an LE-CIS transmission mode with a slave bluetooth device, the LE-CIS transmission mode being established based on a BLE transmission mode. The method shown in fig. 5 includes the steps of:

s501, acquiring all CIS events in the synchronous connection group.

For example, as shown in fig. 1, the slave bluetooth device includes a left earphone device and a right earphone device, where the CIS streams of the left earphone device and the CIS streams of the right earphone device may form a synchronous connection group, and as shown in fig. 2, CIS streams in the same synchronous connection group have the same ISO time interval, and each CIS event includes a plurality of CIS sub-events, such as sub-event 1 and sub-event 2 included in event X in fig. 2.

As a possible implementation, the specific number of CIS events may be configured according to the requirements of bluetooth data transmission, which the present application does not limit in any way.

S502, configuring at least one CIS sub-event in each CIS event as a common event.

As a possible implementation, the selection manner of the common event may be: the last sub-event in the individual CIS events is configured as the common event, such as sub-event 2 in fig. 2. Alternatively, all sub-events located after the m-last position in each CIS event are configured as sub-events, where m is a positive integer greater than 1, for example, assuming that event X in fig. 2 includes 3 sub-events, sub-event 1, sub-event 2, and sub-event 3 in sequence, where m is taken to be 3, both sub-event 2 and sub-event 3 may be configured as common events.

Wherein the common event overlaps with the BLE connection event, that is, the ISO time interval of the common event has an intersection time period with the connection interval corresponding to the connection event of the BLE transmission mode.

In one embodiment, before the step S502, the method further includes: acquiring an ISO time interval of the LE-CIS transmission mode and a connection interval of the BLE transmission mode; and adjusting the connection interval to be n times of the ISO time interval, wherein n is an integer greater than or equal to 1.

By the above adjustment method for the two time intervals of CIS and BLE, the common event can be aligned over a plurality of periods, so that the BLE data packet can be effectively transmitted over the common event over a plurality of periods.

In one embodiment, the start time of the connection interval is aligned with the start time of a target common event, which is a common event of the 1 st ISO time interval corresponding to the connection interval.

It should be noted that, after the BLE connection transmission mode is established, the master bluetooth device may have a fixed connection interval, and modify the value of the connection interval, and modify the starting position of the connection interval, so as to align with the starting point of the common event, so as to ensure that the BLE data packet can be transmitted on the common event.

As a possible implementation manner, when n is 1, the connection interval is equal to the ISO time interval, then each set common event is the target common event, the ISO time interval and the connection interval are in a cross overlapping relationship, the cross portion is the time interval portion of each common event, and each common event can be used for transmitting the BLE data packet. For example, as shown in fig. 6, assuming that the last sub-event of each CIS event is set as the common event, the start time of the common event is the start position of the last sub-event of each CIS event, and when n is taken to be 1, the master bluetooth device sets the start position of the time interval of the BLE data packet to the start position of the last sub-event of each CIS event, so that the time alignment can be achieved.

As another possible embodiment, when n is taken to be 2, the connection interval is an ISO time interval of 2 times, if the start time of the connection interval is guaranteed to be aligned with the start time of the target common event, that is, the start time of the common event of 1 st ISO time interval is aligned, the start time of the common event of 2 nd ISO time interval will not be aligned, at this time, it may be considered that only 1 st common event is a valid common event, CIS data packets and BLE data packets may be transmitted, and the common event of 2 nd ISO time interval transmits CIS data packets only as a sub-event of CIS event. Similarly, when n is a positive integer such as 3, 4, etc., reference may be made to the case when n is 2, and the description of the present application is omitted here.

And S503, transmitting a BLE data packet or a CIS data packet based on the common event.

In one embodiment, the step S503 includes: determining a current priority of the common event; if the current priority is that the BLE data packet is higher than the CIS data packet, transmitting the BLE data packet based on the common event; and if the current priority is that the CIS data packet is higher than the BLE data packet, transmitting the CIS data packet based on the common event.

It should be noted that, the LE-CIS transmission mode and the BLE transmission mode may have priority levels differentiated on the common event, the priority level of the CIS data packet may be higher than the priority level of the BLE data packet or lower than the priority level of the BLE data packet, and the master bluetooth device may preferentially transmit the data packet with high priority on the common event.

In one embodiment, the determining the current priority of the common event includes: judging whether the preamble sub-event of the common event successfully receives a CIS data packet; if yes, determining that the current priority of the common event is that a BLE data packet is higher than a CIS data packet; if not, determining that the current priority of the common event is that the CIS data packet is higher than the BLE data packet.

For example, referring to fig. 6, the CIS flow has 3 sub-events in a CIS event, and determines that the 3 rd sub-event is taken as a common event, in CIS event 1, the CIS packet fails to be received in the 1 st sub-event, and is successfully received in the 2 nd sub-event, then the 3 rd sub-event is an idle sub-event, at this time, the BLE packet has a higher priority than the CIS packet, and can be used by BLE as a connection event to transmit the BLE packet; in CIS event 2, the CIS packet is successfully received in the 1 st sub event, the 2 nd sub event is an idle event, but is not a set common event, so that the sub event is skipped, the 3 rd sub event is an idle event, and at this time, the priority of the BLE packet is higher than that of the CIS packet, and is also used by BLE as a connection event to transmit the BLE packet; in CIS event 3, the data packet fails to be received in the 1 st sub-event and fails to be received in the 2 nd sub-event, and then the 3 rd sub-event is not an idle event, and the priority of the BLE data packet is lower than that of the CIS data packet, so that the BLE data packet is used as a sub-event of the CIS to transmit the CIS data packet.

As a possible implementation manner, both LE-CIS and BLE transmission modes may respectively set a timeout reminding parameter, where the timeout reminding parameter is, for example, 1s, and if there is no interaction between the master bluetooth device and the slave bluetooth device of the CIS exceeding the timeout reminding parameter, it is determined that the LE-CIS is disconnected, and BLE is the same.

It should be noted that, based on the above manner of determining the priority, the LE-CIS transmission mode has a plurality of sub-events and priority of the common event, there is a low possibility that there is no interaction within the timeout reminding parameter of the LE-CIS transmission mode, however, for the BLE transmission mode, since communication is performed only in the common event and the priority is lower than that of the CIS, if the CIS data packet in the CIS event is always transmitted failure, the NSE sub-event of the CIS event is used for CIS communication, and the duration of the ISO time intervals in this case will easily cause the BLE to exceed the timeout reminding parameter of the LE-CIS transmission mode, and there is a risk of disconnection. To this end, the master bluetooth device may determine the current priority in combination with a timeout alert parameter for BLE.

In one embodiment, before determining whether the preamble sub-event of the common event successfully receives the CIS data packet, the method further includes: setting a timeout reminding parameter of the BLE transmission mode; and if the time interval of the last successful BLE data packet based on the BLE transmission mode does not exceed the overtime reminding parameter, executing the judgment on whether the preamble sub-event of the common event successfully receives the CIS data packet.

For example, assuming that the timeout alert parameter of BLE is set to 1s, the master bluetooth device may determine that the time interval does not exceed the timeout alert parameter when detecting that the end time of the last successful transmission of the BLE data packet in the BLE transmission mode is 500ms according to the current time, and then the above-mentioned method for determining whether the preamble sub-event of the common event successfully receives the CIS data packet may be performed.

In one embodiment, if the time interval for successfully transmitting the BLE data packet based on the previous time of the BLE transmission mode exceeds the timeout alert parameter, the current priority of the common event is determined to be that the BLE data packet is higher than the CIS data packet.

In this way, when the time interval of the last successful transmission of the BLE data packet in the BLE transmission mode exceeds the timeout reminding parameter, in the subsequent common event, the priority of the BLE data packet is higher than that of the CIS data packet, that is, whether the common event is an idle event in the CIS or not, the common event is communicated by the BLE transmission mode.

In one embodiment, the determination of the timeout alert parameter for BLE may be performed before the common event arrives.

In one embodiment, the setting the timeout alert parameter of the BLE transmission mode includes: acquiring the preset timeout time of the BLE transmission mode; and setting a timeout reminding parameter of the BLE transmission mode according to the timeout time.

It should be noted that, the timeout period (timeout) is a value preset by the system when the BLE transmission mode is established, and the setting of the timeout alert parameter may refer to the value. For example, the timeout alert parameter may be timeout/2 or timeout/3, which is not limited in any way by the present application.

For another example, referring to fig. 7, the last event of each CIS event is set as a common event. In the CIS event 1, the CIS data packet fails to be received in the 1 st sub event and fails to be received in the 2 nd sub event, so that the 3 rd sub event is not an idle event and is used as a sub event for transmitting the CIS data packet by the CIS; the method comprises the steps that a plurality of CIS events are continued, then before a CIS event n occurs, the time interval of BLE from last successful transmission of a BLE data packet reaches the set value of the overtime reminding parameter, at the moment, the priority of the BLE data packet is improved, in the CIS event n, CIS reception fails in the 1 st sub event and the 2 nd sub event, and the 3 rd common event is used for BLE communication by BLE to transmit the BLE data packet; after successful interaction of BLE, the time interval for successfully transmitting the BLE data packet is refreshed, in CIS event n+1, the time interval for successfully transmitting the BLE data packet last time does not reach the set value of the overtime reminding parameter, the priority of the CIS data packet is recovered, CIS reception fails in the 1 st and 2 nd sub-events, and the 3 rd common event is used as a sub-event for transmitting the CIS data packet by the CIS.

Therefore, by the event configuration method provided by the application, when the master Bluetooth device and the slave Bluetooth device establish the LE-CIS transmission mode and the BLE transmission mode simultaneously, the master Bluetooth device can acquire all CIS events of the synchronous connection group and configure at least one sub-event in all the CIS events as a common event, and the common event can be used for transmitting CIS data packets and can also be used for transmitting BLE data packets. Through the mode of setting up the sharing incident for BLE data package and CIS data package all can be transmitted on this sharing incident, have effectively avoided the extravagant problem of bandwidth, have improved bandwidth utilization, and based on the setting to CIS data package and BLE data package priority, have alleviateed the influence to CIS and BLE double link normal communication to the maximum extent, have improved communication efficiency.
