Description

Background
With the wide application of the Bluetooth 5.0 technical standard in 2016 of the Bluetooth alliance, the Bluetooth second broadcast communication (Bluetooth Secondary adaptation) is a packet sending method introduced by the Bluetooth 5.0 protocol to expand the Bluetooth broadcast communication (Bluetooth adaptation) function, and aims to enable the broadcast communication (adaptation) to carry more information under the condition of reducing the congestion of a Bluetooth broadcast Channel (Bluetooth adaptation Channel). The second broadcast communication Channel Packet (Packet on Secondary Advertising Channel) may need to be attached to a broadcast communication (Advertising) on the Primary Channel (Primary Channel), and a specific sending location thereof needs to be determined and displayed in the Primary Channel Advertising Packet before sending the corresponding Primary Channel broadcast Packet (Primary Channel Advertising Packet).
Thus, if a synchronous link already exists on the device, such as: if the Bluetooth voice call (SCO/eSCO), the Bluetooth mouse keyboard, the Tag Sensor (Sensor Tag) and the like are not avoided, collision is easily caused, so that a Bluetooth Secondary adaptive packet cannot be sent out or a synchronous link packet (synchronous link packet) cannot be sent out, and the problem of Quality of Service (QoS) is caused.
At present, in the prior art, the position of a second broadcast communication data packet (Secondary acknowledgement packet) is determined to avoid mainly by not considering an existing synchronous link (synchronization link) or by adopting a random method, but the problem of collision between the two cannot be well handled or avoided.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a bluetooth data transmission method, as shown in fig. 1, the method includes:
s11, acquiring the topological structure of the first synchronous link on the current equipment;
s12, mapping the first synchronous link or the first broadcast communication data packet on a preset time axis;
s13, determining the time position for sending the second synchronous link or the second broadcast communication data packet on the mapped preset time axis;
and S14, after the first broadcast communication data packet is sent, sending a second synchronous link or a second broadcast communication data packet according to the time position.
The bluetooth data transmission method provided by the embodiment of the invention firstly obtains the topological structure of the synchronous links on the current equipment, namely all the synchronous links connected currently, and maps the synchronous links or the first broadcast communication data packet to the preset time axis, namely, the clocks of the master equipment, the slave equipment and each link are unified, the idle time slot is accurately determined, and then the second synchronous link and the second broadcast communication data packet are distributed, so that the conflict between the synchronous links and the broadcast communication is avoided, and the efficient transmission of the bluetooth data is realized.
Wherein, because the clock (clock) in the bluetooth links (links) is divided into a master clock (master clock) and a slave clock (slave clock), the clock of each link may not be the same, but the basic time slice of each clock is in time slot (frame: 1250 us). Therefore, in order to allocate the timeslot frames to the second synchronous link or the second broadcast communication reservation accurately, the method described in this embodiment needs to accurately count the timeslot frames that have been reserved by other synchronous links (syncronous links) on the time axis where the communication link of the current device is located, and find out the free timeslot frames to give a new syncronous link or the second broadcast communication.
Therefore, in the method of this embodiment, the topological structure of the synchronous link on the current device, that is, the currently existing synchronous links, is first checked and obtained, the occupation situation of the time slot frames of the synchronous link on the current device on the respective clock time axes is mapped onto the preset time axis corresponding to the desired clock, a time sequence mapping table (base bitmap table) of the reserved occupation of the time slot frames is obtained, and the time slot frame occupation situation on the mapped preset time axis is accurately allocated to the new synchronous link or the second broadcast communication, so that the conflicts between the synchronous links and the broadcast link are effectively avoided.
Optionally, as shown in fig. 2, the mapping the first synchronization link or the first broadcast communication packet on a preset time axis includes:
s121, acquiring time slot information of a first synchronous link or time slot information of a first broadcast communication data packet;
and S122, mapping the first synchronous link or the first broadcast communication data packet on a preset time axis according to the time slot information of the first synchronous link or the time slot information of the first broadcast communication data packet.
For example, the mapping the first synchronization link or the first broadcast communication packet on the preset time axis according to the time slot information of the first synchronization link or the time slot information of the first broadcast communication packet may include:
when the corresponding clock of the preset time axis is consistent with the corresponding clock of the first broadcast communication, mapping the corresponding synchronous link on the preset time axis according to the time slot information of each synchronous link;
and when the clock corresponding to the preset time axis is inconsistent with the clock corresponding to the first broadcast communication, mapping the corresponding synchronous link and the first broadcast communication on the preset time axis according to the time slot information of each synchronous link and the time slot information of the first broadcast communication.
Optionally, after the mapping the first synchronization link or the first broadcast communication packet on a preset time axis according to the time slot information of the first synchronization link or the time slot information of the first broadcast communication packet, the method further includes:
and S123, mapping the extra consumption time slot corresponding to the mapping process of the first synchronous link or the first broadcast communication data packet on the preset time axis.
Specifically, in this embodiment, in order to obtain the timing mapping table more accurately, the method of this embodiment also maps the time consumed in the mapping process to the preset time axis correspondingly, and clearly and accurately obtains the situation occupied by the existing link timeslot, for example: as shown in fig. 3, two links existing in the topology of the first synchronization link on the current device are the first link and the second link, respectively, and a frame needs to be reserved for the newly inserted third link. The frame occupation conditions of the second link and the third link are mapped to a clock time axis of the third link to obtain a time sequence mapping table, that is, the clock time axis of the third link is taken as a preset time axis in this example.
Optionally, the determining, on the mapped preset time axis, a time position for transmitting the second synchronization link or the second broadcast communication packet includes:
s131, analyzing the mapped occupation information of the preset time shaft;
s132, determining the time position corresponding to the second synchronous link or the second broadcast communication data packet on the preset time axis according to the occupation information and the second synchronous link or the occupation information and the time slot information of the second broadcast communication data packet.
Optionally, before the determining, according to the occupancy information and the second synchronous link, or the occupancy information and the timeslot information of the second broadcast communication data packet, to send the corresponding time position of the second synchronous link or the second broadcast communication data packet on a preset time axis, the method further includes:
judging whether the vacant time position of the preset time shaft is enough to accommodate the second synchronous link or the second broadcast communication data packet or not according to the mapped occupation information of the preset time shaft and the second synchronous link or the mapped occupation information of the preset time shaft and the time slot information of the second broadcast communication data packet;
when the vacant time positions are sufficiently accommodated, directly determining the corresponding time positions of the second synchronous link or the second broadcast communication data packet on the preset time axis;
and when the vacant time positions cannot be accommodated, sending the corresponding time positions of the second synchronous link or the second broadcast communication data packet on a preset time shaft according to a preset priority order.
Specifically, as shown in fig. 4, when the method of this embodiment obtains the timing sequence mapping table on the synchronization link of the current device, a reasonable time position can be determined according to the occupation situation of the time slot frame on the timing sequence mapping table, and a new service (i.e., the second synchronization link and the second broadcast communication) is inserted. In case of congestion, or to make reservations for future critical traffic such as voice synchronized link (SCO/eSCO) etc.,
meanwhile, when the time position is sufficiently accommodated, the method adjusts the sending time position of the second synchronous link or the second broadcast communication data packet to the determined sufficient idle time position by adjusting the preset parameter (such as Delta parameter); when the time position cannot be accommodated, the method of the embodiment further determines the sent time position by adopting a preset strategy, so that the quality of the bluetooth communication is optimized. For example: the preset strategy can determine the optimal sending time position according to the priority sequence of the parameters, wherein the priority of the parameters can be set to be that the priority of the instantaneous times is higher than the length of the link session (namely the time slot length); in addition, the method of this embodiment cannot avoid a collision through adjustment of the preset parameters, and finally performs adjustment through the priority order of the links, so as to ensure normal communication of sessions of the links.
For example, as shown in fig. 4, when the time location is sufficiently accommodated, the Delta parameter is adjusted to be 3, and the time slot frame scheme reserved for the new synchronization link service is the best, and in the case of acquiring the maximum number of instants (i.e., the number of sessions), the expected window (window) can be acquired each time.
An embodiment of the present invention further provides a bluetooth data transmission apparatus, as shown in fig. 5, the apparatus includes:

and a transmission control unit 14, configured to transmit the second synchronization link or the second broadcast communication packet according to the time position after transmitting the first broadcast communication packet.
The bluetooth data transmission apparatus provided in the embodiment of the present invention first obtains the topology structure of the synchronization link on the current device, that is, all the synchronization links currently connected, by the obtaining unit 11, and maps the synchronization link or the first broadcast communication data packet onto the preset time axis by the mapping unit 12, that is, by unifying the clocks of the master device, the slave device, and each link, the idle time slot is accurately determined, and then the second synchronization link and the second broadcast communication data packet are distributed, thereby avoiding the collision between the synchronization link and the broadcast communication, and realizing the efficient transmission of the bluetooth data.
Wherein, because the clock (clock) in the bluetooth links (links) is divided into a master clock (master clock) and a slave clock (slave clock), the clock of each link may not be the same, but the basic time slice of each clock is in time slot (frame: 1250 us). Therefore, in order to allocate the timeslot frames to the second synchronous link or the second broadcast communication reservation accurately, the method described in this embodiment needs to accurately count the timeslot frames that have been reserved by other synchronous links (syncronous links) on the time axis where the communication link of the current device is located, and find out the free timeslot frames to give a new syncronous link or the second broadcast communication.
Therefore, the device described in this embodiment first checks and obtains the topology structure of the synchronous link on the current device, that is, the currently existing synchronous links, and maps the occupation situation of the synchronous link on the current device on the time slot frame on the time axis of each clock onto the preset time axis corresponding to the expected clock, so as to obtain a time sequence mapping table (base bitmap table) of reserved occupation of the time slot frame, and accurately allocates the time slot frame to the new synchronous link or the second broadcast communication according to the time slot occupation situation on the preset time axis after mapping, thereby effectively avoiding the conflict between the synchronous links and between the synchronous link and the broadcast link.
