Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.
In applications where BLE devices have multiple connection links, there is a specific application scenario, where there is a need for data transmission on only one link (active link) at a time, and other links (idle links) need not transmit data, but still need to maintain connection of the idle links, so that a user can conveniently transmit data through the other links after a certain time, thereby improving user experience, and avoiding reestablishing connection when data is required to be transmitted through the other links.
The BLE device can only perform data interaction with one opposite terminal device through one link at the same time, so that the BLE device performs data interaction with each opposite terminal device through each link in an alternating manner by setting the priority, thereby maintaining the connection of a plurality of links.
As shown in fig. 1, BLE device G is connected to BLE device a and BLE device B via links a and B, respectively. If the BLE device G only needs to perform data interaction with the BLE device a in a certain period of time, the BLE device G does not need to perform data interaction with the BLE device B, but still needs to maintain connection of the link B, so that the link B is convenient to be used when the BLE device G needs to perform data interaction with the BLE device B after a certain period of time.
As shown in the interactive timing diagrams of fig. 2 and 3, BLE device G may be enabled to maintain a link connection with BLE device a and BLE device B. Fig. 3 shows a schematic data interaction timing diagram when the BLE device G is different from the connection event anchor points of the two peer devices, and fig. 4 shows a schematic data interaction timing diagram when the BLE device G is identical to the connection event anchor points of the two peer devices. It should be appreciated that a connection event is a process in which a connection state device starts air interface data interaction to ends air interface data interaction within one connection time interval (Connection Interval, CI). And the connection event anchor point is a time starting point for starting data interaction with the opposite terminal equipment when the equipment maintains connection.
In the process of performing data interaction between the BLE device G and the opposite terminal device through multiple links, each interaction can only start to perform data interaction from the starting point of one CI corresponding to each link. The CI may also be expressed as a data interaction period for each link. The time for data interaction within each CI is determined by the size of the data volume, but cannot exceed the time bandwidth of one CI.
As shown in fig. 2 and 3, after the BLE device G completes one data interaction through the link a, the data interaction of the link a must be stopped when the data interaction needs to be performed through the link B. After the link B completes one data interaction, if the data interaction needs to be performed through the link a, the data interaction of the link B must be stopped. That is, after one data interaction is completed through the link a, the priority of the data interaction through the link a is reduced to the lowest, and at this time, the priority of the data interaction through the link B is the highest. After one data interaction is completed through the link B, the priority of the data interaction through the link B is reduced to be the lowest, and at the moment, the priority of the data interaction through the link A is the highest.
If the BLE device G starts to complete data interaction at the start point of one CI through the link a, and if the link B does not have a data transmission requirement, the BLE device G may continue to perform data interaction through the link a until data transmission on the link B starts or the one CI corresponding to the link a ends.
As shown in fig. 4, BLE device G is connected to BLE device A, BLE device B, BLE device C and BLE device D by link a, link B, link C, and link D, respectively. If the BLE device G only needs to interact with the BLE device a in a certain period of time, the BLE device G does not need to interact with the BLE device B, BLE device C and the BLE device D, but still needs to maintain the connection of the link B, the link C and the link D, so that the BLE device G needs to use the link B, the link C and the link D when interacting with the BLE device B, BLE device C and the BLE device D after a certain period of time.
Fig. 5 shows a schematic diagram of data interaction timing when the BLE device G is different from the connection event anchor points of the four peer devices, and fig. 6 shows a schematic diagram of data interaction timing when the BLE device G is identical to the connection event anchor points of the four peer devices.
As shown in fig. 5 and fig. 6, the priority of the BLE device G for data interaction with the peer device through different links is ordered from top to bottom: link a, link B, link C and link D; when the BLE device starts to finish one-time data interaction with the opposite terminal device through the link a at the starting point of the CI corresponding to the link a, the priority of the link a is immediately reduced to the lowest, and at this time, the priorities of the different links are ordered from top to bottom as follows: link B, link C, link D and link a; when the BLE device starts to finish one data interaction with the peer device through the link B at the start point of one CI corresponding to the link B, the priority of the link B is immediately reduced to the lowest, and at this time, the priorities of the different links are sorted from top to bottom as follows: link C, link D, link a and link B; similarly, after the BLE device completes one data interaction through the starting point of one CI corresponding to each link, the priority of the link is immediately reduced to the lowest.
After the BLE device G starts to perform data interaction with the peer device through the link a at the start point of one CI corresponding to the link a, the BLE device G starts to perform data interaction with the peer device through the link B at the start point of one CI corresponding to the link B, and so on, which are not described in detail for brevity.
Although the above scheme can maintain the link connection between the BLE device G and the plurality of peer devices, the data transmission rate of the link (active link) that needs to transmit a large amount of data is low, and the link (idle link) that needs to transmit data transmits null data packets, which wastes power consumption.
Therefore, the embodiment of the application provides a data transmission method 700, which can improve the data transmission rate.
Fig. 7 shows a flow chart of a method 700 of data transmission according to an embodiment of the application. The method 700 includes:
710, the first device performs data interaction with the second device through the first link, and the first device performs data interaction with the third device through the second link; it should be appreciated that the first link and the second link are bluetooth communication links.
The first device determines 720 that the first link is an active link and that the second link is an idle link.
It should be understood that the first device may perform data interaction with at least two devices through at least two links, and the idle link may be one or multiple links.
An active link is a link that has data transmission requirements. When there is a data transmission requirement at either end of the link, the link may be made active.
Optionally, in one embodiment, if the first device needs to transmit data over the first link, the first link is determined to be an active link.
Optionally, in an embodiment, if the first device receives an instruction message sent by a second device corresponding to the first link, the instruction message is used to instruct the second device corresponding to the first link to need to transmit data to the first device through the first link, and then the first link is determined to be an active link. When the second equipment corresponding to the first link needs to transmit data through the first link, an instruction message is sent to the first equipment; or when the user needs to transmit data through the first link, the user can touch a display screen or a button of the second device corresponding to the first link, so that the second device sends an instruction message to the first device; the instruction message is for the first device to determine the first link as an active link.
Optionally, in an embodiment, the first device determines that the first link is an active link according to a user indication. For example, when a user needs to transmit data over the first link, a display screen or button of the first device may be touched to cause the first device to determine the first link as an active link.
And 730, stopping the data interaction of the idle link in N CIs corresponding to the idle link after the first device completes one-time data interaction in one connection time interval CI corresponding to the idle link through the idle link, wherein N is a positive integer. The N CIs may be understood as Latency periods corresponding to the idle links, and data interaction is not performed through the idle links in the Latency periods, i.e., the Latency periods are skipped.
The first device can perform data interaction through the idle link in the next CI after the N CIs corresponding to the idle link, so as to avoid disconnection of the idle link. In addition, the data packets transmitted on the idle link are null data packets, and the data packets with data are transmitted on the active link.
Optionally, the N is not less than the number of links. The number of N is not smaller than the number of links, so that the rate of data transmission through the active links can be effectively improved. The larger N is, the higher the rate of data transmission over the active link is, with the assurance that the idle link is not disconnected.
740, the first device performs data interaction through the active link in each CI corresponding to the active link during the period that the data interaction of the idle link is stopped. It should be understood that when the idle links are multiple, data interaction can be performed through the active links in each CI corresponding to the active links when all idle links stop data interaction.
Optionally, the priority of the first device for data interaction through the idle link is higher than the priority of the first device for data interaction through the active link. In this way, the first device first judges whether the idle link is in the latency period, and under the condition that the idle link is in the latency period, data interaction is performed in each CI corresponding to the active link through the active link.
In the technical scheme of the embodiment of the application, after completing one data interaction in one CI corresponding to an idle link through the idle link, the first device stops the data interaction of the idle link in N CIs corresponding to the idle link, and performs the data interaction through an active link in the period of stopping the data interaction corresponding to the idle link. The technical scheme provided by the embodiment of the application reduces the times of data interaction through the idle link and increases the times of data transmission through the active link, thereby improving the data transmission rate.
In one embodiment, when there are only two links for the first device, as shown in fig. 1. One of the links is an active link and the other link is an idle link. Fig. 8 shows a timing diagram of data interaction when the connection event anchor points of the first device and the different second device are different, and fig. 9 shows a timing diagram of data interaction when the connection event anchor points of the first device and the different second device are the same.
As shown in fig. 8 and fig. 9, after the first device completes data interaction in one connection time interval CI corresponding to the idle link through the idle link, stopping data interaction of the idle link in 5 CIs corresponding to the idle link (stopping data interaction through the idle link in a latency period corresponding to the idle link), and performing data interaction through the idle link in the next CI after the 5 CIs corresponding to the idle link. And the BLE equipment performs data interaction through the active link in each CI corresponding to the active link in the period of stopping the data interaction of the idle link. It should be appreciated that a successful data interaction is guaranteed before stopping the data interaction through the idle link, so that stability can be considered and disconnection of the idle link can be prevented.
As shown in fig. 8, when the idle link is hidden, the first device may use the entire bandwidth time in each CI corresponding to the active link to perform data interaction, so that the efficiency of transmitting data through the active link is improved. In addition, in the latency period of the idle link, transmission of an idle data packet is not performed through the idle link, so that power consumption of the BLE device is reduced.
In another embodiment, when four links exist for the first device, the four links include link a, link B, link C, and link D as shown in fig. 3. Assuming that the link A is determined to be an active link, and the link B, the link C and the link D are idle links, after finishing one data interaction through the idle links, stopping the data interaction of the idle links in 4 CIs of the idle links. Fig. 10 shows a timing diagram of data interaction when the connection event anchor points of the first device and the different second device are different, and fig. 11 shows a timing diagram of data interaction when the connection event anchor points of the first device and the different second device are the same.
The first device performs data interaction through the active link in each CI corresponding to the active link (the link a) during the period that the data interaction of the idle links (the link B, the link C and the link D) is stopped. The priority of the first device for data interaction through the idle link is higher than the priority of the first device for data interaction through the active link.
As shown in fig. 10, the first device performs data interaction during a period when data interaction of the idle link is stopped through a link a, after stopping data interaction through the active link, the first device completes data interaction through the link B once, starts data interaction through the link C at a start point of a next CI, starts data interaction through the link D at a start point of a next CI after completing data interaction through the link C, enters a period when data interaction of the idle link is stopped after performing data interaction through the link D, and performs data interaction through the active link in each CI corresponding to the active link. Similarly, the description is omitted for brevity. It will be appreciated that the longer the latency of the idle link, i.e. the greater the N, the higher the rate at which data is transmitted over the active link.
As shown in fig. 11, after the first device stops data interaction through the active link, when data interaction through the idle link is required (outside the period in which data interaction of the idle link is stopped), the priority of data interaction through the idle link is ordered from high to low: link B, link C, link D. When the first device starts to finish one data interaction through the link B at the starting point of one CI corresponding to the link B, the priority of the link B is immediately reduced to the lowest of the idle links, and at this time, the priority of the data interaction through the idle links is ranked from top to bottom as follows: link C, link D and link B; and so on, for brevity, no further description will be made.
The first device may have multiple links connected to other devices, and the at least two links described in the embodiments of the present application are only two or four links, which are merely examples, and are not limited in any way.
