The embodiment of the present application may further include other devices that communicate with the electronic device 101 or the electronic device 102, and the embodiment of the present application is not limited.
In the embodiment of the present application, the electronic devices 101 and 102 may have the capability of data transmission by using bluetooth technology. The electronic devices 101 and 102 may also be referred to as terminals, and may refer to various forms of User Equipment (UE), access terminals, subscriber units, subscriber stations, Mobile Stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents, or user devices. The electronic device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, an electronic device in a fifth generation mobile communication (5G) network or an electronic device in a future evolution public land mobile communication network (PLMN), and the like, which are not limited in this embodiment.
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 divided into three types, namely ACL data, SD data and protocol data of a network layer. When the bluetooth technology is used for service data transmission, each type of data may include control data and user data of the same service, or may include data of different services, however, the urgency of scheduling transmission of the control data, the user data, and the data of different services may be different, so that the bluetooth control layer may only process the data according to the principle of processing first arrival and first arrival, which may result in some data with high urgency not being processed in time, resulting in a traffic jam or a connection link being disconnected.
The embodiment of the application provides a data transmission method 200. In the method, the electronic equipment transmits data to be transmitted to a logic channel of a priority level according to the priority level of the data to be transmitted; when an air interface data packet transmission event is triggered, the electronic equipment selects the data to be transmitted of the logic channel with the highest priority from all the logic channels of the priorities to perform packet transmission, so that the data with the high priority can be preferentially transmitted, and the problem that certain data with high urgency cannot be timely processed to cause traffic jam or disconnection of a connection link is avoided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a data transmission method 200 according to an embodiment of the present application, where 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 level one may be the highest priority or the lowest priority, which is not limited in this 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 a service type to which the data to be sent belongs, a service priority, and a data type. The service type can be an audio and video service type, a file transmission service type, a web browsing service type and the like; the service priority to which the data to be sent belongs may be the highest priority, or may 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, and the like.
For example, assuming that the service type to which the data to be sent belongs is a voice video service type, 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 sent is the highest priority; the electronic equipment can determine that the priority of the data to be sent is the second highest priority when the service type to which the data to be sent belongs is a voice video service type, the service priority is the highest priority and the data type is user data; if the service type to which the data to be sent belongs is a file transmission service type, the service priority is the lowest priority, and the data type is user data, the electronic device may determine that the priority of the data to be sent is the lowest priority.
In an optional implementation manner, before the data to be sent is transmitted to the logical channel of the priority, the logical channel of the priority is created according to the logical channel number, the priority, and the size of the storage space 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 a logical channel, and the index value does not represent the priority level 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, which correspond to numbers 1, 2, and 3, and the created logical channel with the priority number is 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 sent belongs refers to the priority level of the data to be sent. 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) for storing the data, and may be, for example, 12 Byte.
Optionally, when the storage space of the logical channel with 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 with the priority according to the logical channel number, the priority and the size of the storage space of the service to which the data to be sent belongs.
Optionally, when the storage space of the logical channel of the priority 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 logical channels of the priority as the logical channel corresponding to the data to be sent.
The method comprises the steps of dividing the priority of data to be sent, transmitting the data to be sent to a logic channel of the priority according to the priority of the data to be sent, avoiding the problem that the data with high priority is not processed in time, so that the data with high priority can be transmitted preferentially, and further selecting the data to be sent of the logic channel with the highest priority from all the logic channels of the priority to perform packet transmission when an air interface data packet transmission event is triggered by the electronic equipment.
S202: and when the electronic equipment triggers an air interface data packet transmission event, selecting the data to be transmitted of the logic channel with the highest priority from all the logic channels with the priorities to perform packet transmission.
Understandably, when the electronic device triggers an air interface data packet transmission event, the to-be-transmitted data of the logical channel with the highest priority needs to be selected from all the logical channels with priorities to be packaged and transmitted.
Optionally, the group packet transmission may combine data to be transmitted, add a packet header such as a control character, and then transmit the data. Optionally, the electronic device may trigger an air interface data packet transmission event when receiving the air interface resource configuration information; alternatively, the electronic device may trigger an air interface packet transmission event when receiving a scheduling requirement instruction of the network device.
In an optional implementation manner, before the electronic device selects, from all the priority logical channels, data to be transmitted of a logical channel with the highest priority for packet transmission, the method further includes: the electronic equipment acquires the data to be sent from the logical channel of the priority level and stores the data to be sent into the storage space of the logical channel of the priority level.
Therefore, the embodiment is beneficial to storing the data to be sent with lower priority into the storage space of the logical channel with lower priority, and sending the data to be sent of the logical channel with higher priority.
In an optional implementation manner, after the electronic device selects, from all the priority logical channels, data to be transmitted of a logical channel with the highest priority for packet transmission, the method further includes: and when the electronic equipment receives that the data sent by the group package is confirmed by the opposite terminal, clearing the data sent by the group package from the storage space of the selected logical channel, and updating the size of the storage space of the selected logical channel.
Therefore, the embodiment can clean and update the storage space of the logical channel in time, so that the data to be sent of the priority of the logical channel can be stored.
In the embodiment of the application, the electronic device transmits the data to be transmitted to a logic channel of the priority according to the priority of the data to be transmitted; when the electronic equipment triggers an air interface data packet transmission event, the to-be-transmitted data of the logic channel with the highest priority is selected from all the logic channels with the priorities to be packaged and transmitted. That is to say, the electronic device divides the data to be sent by different priorities and transmits the data to be sent by different priorities to the logical channel corresponding to the priorities, so as to avoid the problem that some data with high urgency cannot be processed in time, which causes traffic jam or disconnection of a connection link.

In an optional implementation manner, the bluetooth host may determine the priority of the data to be sent according to the service type, the service priority, and the data type to which the data to be sent belongs.
In an optional implementation manner, the bluetooth host is further configured to send a logical channel request for creating the priority to the bluetooth control layer according to a logical channel number, a priority, and a storage space size of a 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 further configured to create a logical channel of the priority, and transmit a creation result to the bluetooth host, so that the bluetooth host executes an operation of transmitting the data to be transmitted to the logical channel of the corresponding priority according to the priority of the data to be transmitted.
In an optional implementation manner, the bluetooth control layer is further configured to, before selecting the to-be-transmitted data of the logical channel with the highest priority from all the logical channels with priorities to perform packet transmission, obtain the to-be-transmitted data from the logical channel with the priority, and store the to-be-transmitted data in the storage space of the logical channel with the priority. Optionally, the bluetooth control layer is further configured to store signaling data between the bluetooth control layers that is created without a request from the bluetooth host.
In another optional implementation, the bluetooth control layer is further configured to select, from all the priority logical channels, data to be sent of a logical channel with a highest priority for packet sending, and when it is received that the data sent by the packet is confirmed by an opposite end, clear 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.
Optionally, the related contents of the data transmission device shown in fig. 3 can also be referred to the above-mentioned method embodiment, and are not described in detail here.
In the embodiment of the application, the electronic device comprises a bluetooth control layer and a bluetooth host, wherein the bluetooth host is used for transmitting data to be transmitted to a logic channel with corresponding priority according to the priority of the data to be transmitted; and the Bluetooth control layer is also used for selecting the data to be transmitted of the logical channel with the highest priority from all the logical channels with the priorities to perform packet transmission.

In another optional implementation manner, before the processing unit 401 transmits the data to be sent to the logical channel of the priority, the processing unit 401 creates the logical channel of the priority according to the logical channel number, the priority, and the size of the storage space of the service to which the data to be sent belongs.
