Currently, in the bluetooth standard protocol, the bluetooth protocol stack includes two parts, namely a bluetooth host and a bluetooth control layer, and data between the bluetooth host and the bluetooth control layer is classified into ACL data, SD data and protocol data of a network layer. When the bluetooth technology is used for transmitting service data, each type of data can contain control data and user data of the same service or data of different services, however, the urgency of scheduled transmission of the control data, the user data and the data of different services may be different, so that the bluetooth control layer can only process the data according to the principle of first arrival and first processing, and then certain data with high urgency may not be processed in time, resulting in service blocking or connection link disconnection.
The embodiment of the application provides a data transmission method 200. According to the method, the electronic equipment transmits data to be transmitted to a logic channel of the priority according to the priority of the data to be transmitted; when triggering an air interface data packet transmission event, the electronic equipment selects data to be transmitted of a logic channel with the highest priority from all logic channels with the highest priority to carry out packet transmission, so that the data with the high priority can be transmitted preferentially, and the problem that certain data with high urgency cannot be processed in time, and service is blocked or a connecting link is disconnected is avoided.
Referring to fig. 2, fig. 2 is a flowchart of a data transmission method 200 according to an embodiment of the application, wherein the data transmission method 200 includes, but is not limited to, the following steps:
s201: and the electronic equipment transmits the data to be transmitted to a logic channel of the priority according to the priority of the data to be transmitted.
It is understood that the priority of the data to be transmitted may be divided according to different scheduling requirements for the data to be transmitted, for example, the priority may be divided into a plurality of levels, for example, four levels, according to the different scheduling requirements. The first level may be the highest priority or the lowest priority, which is not limited by the present application.
For example, assuming that the priority of the data to be transmitted is the highest priority, the electronic device transmits the data to be transmitted to the logical channel with the highest priority.
In an alternative embodiment, the priority may be determined according to the service type, service priority, and data type to which the data to be transmitted belongs. The service type may be an audio/video service type, a file transmission service type, a web browsing service type, etc.; the service priority to which the data to be transmitted belongs may be the highest priority, may also be the next highest priority, and so on; the data type to which the data to be transmitted belongs may be control data, user data, or the like.
For example, assuming that the service type to which the data to be transmitted belongs is a voice video service type, when the service priority is the highest priority and the data type is control data, the electronic device may determine that the priority of the data to be transmitted is the highest priority; assuming that the service type to which the data to be transmitted belongs is a voice video service type, when the service priority is the highest priority and the data type is user data, the electronic device can determine that the priority of the data to be transmitted is the next highest priority; assuming that the service type to which the data to be transmitted belongs is a file transfer service type, the priority of the service is the lowest priority, and the data type is user data, the electronic device may determine that the priority of the data to be transmitted is the lowest priority.
In an alternative embodiment, before transmitting the data to be sent to the logic channel with the priority, the logic channel with the priority is created according to the logic channel number, the priority and the storage space size of the service to which the data to be sent belongs.
Alternatively, the logical channel number of the service to which the data to be transmitted belongs may be an index value of the logical channel, where the index value does not represent a level of priority of the logical channel. For example, the logical channel number may be number 1, but does not represent number 1 as the highest priority. For example, assuming that there are three logical channels, respectively corresponding to numbers 1,2, and 3, and the created logical channel with the priority is numbered 4, the electronic device may use the logical channel with the number 4 as the logical channel with the highest priority, or use the logical channel with the number 2 as the logical channel with the highest priority; the priority of the service to which the data to be transmitted belongs refers to the priority level of the data to be transmitted. E.g., highest priority level, next highest priority level, etc. The size of the storage space of the service to which the data to be transmitted belongs refers to the storage space occupied by the data to be transmitted, and the storage space may be represented by a minimum unit (Byte or bit) of the data to be transmitted, for example, may be 12 bytes.
Optionally, when the storage space of the logical channel of the priority is larger than the storage space of the service to which the data to be sent belongs, the electronic device creates the logical channel of the priority according to the logical channel number, the priority and the storage space of the service to which the data to be sent belongs.
Optionally, when the storage space of the priority logical channel is smaller than the storage space of the service to which the data to be sent belongs, the electronic device selects the logical channel corresponding to the highest priority level from the priority logical channels as the logical channel corresponding to the data to be sent.
The method comprises the steps of dividing the priority of the data to be sent, and transmitting the data to be sent to a logic channel with the priority according to the priority of the data to be sent, so that the problem that the data with high priority is not processed in time can be avoided, the data with high priority can be transmitted preferentially, and the electronic equipment selects the data to be sent of the logic channel with the highest priority from all the logic channels with the priority to carry out packet transmission when an air interface data packet transmission event is triggered.
S202: and when the electronic equipment triggers an air interface data packet transmission event, selecting data to be transmitted of a logic channel with the highest priority from all logic channels with the highest priority to perform packet transmission.
It can be understood that when the electronic device triggers an air interface packet transmission event, data to be transmitted of a logical channel with the highest priority needs to be selected from all the logical channels with the highest priority to perform packet transmission.
Optionally, the packet transmission may be performed after adding a packet header such as a control character after combining the data to be transmitted. Optionally, the electronic device may trigger an air interface packet transmission event when receiving the air interface resource configuration information; or, the electronic device may trigger an air interface packet transmission event when receiving a scheduling demand instruction of the network device.
In an optional implementation manner, before the electronic device selects data to be sent of a logical channel with highest priority from all the logical channels with highest priority to perform packet sending, the method further includes: the electronic equipment acquires the data to be sent from the logic channel with the priority, and stores the data to be sent into a storage space of the logic channel with the priority.
It can be seen that this embodiment is advantageous for storing the data to be transmitted of lower priority in the storage space of the logical channel of lower priority, while transmitting the data to be transmitted of the logical channel of higher priority.
In an optional implementation manner, after the electronic device selects data to be sent of a logical channel with highest priority from all the logical channels with highest priority to perform packet sending, the method further includes: and when the electronic equipment receives the data sent by the group of packets and is confirmed by the opposite terminal, the electronic equipment clears the data sent by the group of packets from the storage space of the selected logic channel and updates the size of the storage space of the selected logic channel.
It can be seen that the embodiment can timely clear and update the storage space of the logic channel, so that the data to be sent of the priority of the logic channel can be stored.
In the embodiment of the application, the electronic equipment transmits the data to be transmitted to a logic channel of the priority according to the priority of the data to be transmitted; when triggering an air interface data packet transmission event, the electronic equipment selects data to be transmitted of a logic channel with the highest priority from all logic channels with the highest priority to perform packet transmission. That is, the electronic device divides the data to be sent with different priorities, and transmits the data to be sent with different priorities to the logic channels corresponding to the priorities, so that the problem that certain data with high urgency cannot be processed in time, and service is blocked or a connection link is disconnected is avoided.

In an optional implementation manner, the bluetooth host is further configured to send a request for creating the logical channel of the priority to the bluetooth control layer according to the logical channel number, the priority and the storage space size of the service to which the data to be sent belongs, where the request for creating the logical channel of the priority includes the logical channel number, the priority and the storage space size of the service to which the data to be sent belongs; the Bluetooth control layer is also used for creating the logic channel of the priority and transmitting the creation result to the Bluetooth host, so that the Bluetooth host executes the operation of transmitting the data to be transmitted to the logic channel of the corresponding priority according to the priority of the data to be transmitted.

Optionally, the bluetooth control layer is further configured to store signaling data between bluetooth control layers that is created without a bluetooth host request.
In another alternative embodiment, the bluetooth control layer is further configured to, after selecting, from all the logical channels with priority, data to be transmitted of the logical channel with highest priority for packet transmission, clear, when receiving the data sent by the packet and acknowledged by the peer, the data sent by the packet from the storage space of the selected logical channel, and update the size of the storage space of the selected logical channel; the bluetooth control layer is further configured to notify the bluetooth host of the updated size of the storage space of the selected logical channel.
