Abstract

The present application provides a method for configuring a Bluetooth connection parameter, and an electronic device. Take connecting a mobile phone to Bluetooth headphones as an example. When the mobile phone detects an incoming call event, a user immediately opens a headphone box, hoping that the Bluetooth headphones are connected to the mobile phone as soon as possible to answer the phone. At this time, a high duty ratio can be configured for the mobile phone to accelerate the speed at which the Bluetooth headphones are connected to the mobile phone, and reduce the time delay when the Bluetooth headphones are connected to the mobile phone. After the mobile phone establishes a Bluetooth connection with the Bluetooth headphones, a low duty ratio can be configured for the mobile phone to reduce the power consumption of the mobile phone. Embodiments of the present application can improve the flexibility for configuring the Bluetooth connection parameter for the mobile phone and improve the user experience.

其中，Host协议栈定义了蓝牙框架中的多个应用(profile)和核心协议(protocol)，每个profile定义了各自相应的消息格式与应用规则，profile是蓝牙服务(application)。为了实现不同平台下的不同设备的互联互通，蓝牙协议为各种可能的、有通用意义的应用场景，都制定的了规范，如蓝牙音频传输模型协定(advanced audio distribution profile，A2DP)、蓝牙免提协议(hands-free profile，HFP)等等。Among them, the Host protocol stack defines multiple applications (profiles) and core protocols (protocol) in the Bluetooth framework, each profile defines its own corresponding message format and application rules, and the profile is a Bluetooth service (application). In order to realize the interconnection and intercommunication of different devices under different platforms, the Bluetooth protocol has formulated specifications for various possible and universal application scenarios, such as the Bluetooth audio distribution profile (advanced audio distribution profile, A2DP), Bluetooth free Proposal agreement (hands-free profile, HFP) and so on.

其中，HCI为上层协议提供了进入链路管理器的统一接口和进入基带的统一方式,在主机核心协议栈和控制器之间会存在若干传输层,这些传输层是透明的，完成传输数据的任务，蓝牙技术联盟(Bluetooth special interest group，SIG)规定了四种与硬件连接的物理总线方式,即四种HCI传输层:USB，RS232，UART和PC卡。Among them, HCI provides a unified interface for the upper layer protocol to enter the link manager and a unified way to enter the baseband. There will be several transmission layers between the host core protocol stack and the controller. These transmission layers are transparent and complete the transmission of data. For the task, the Bluetooth Special Interest Group (SIG) specifies four physical bus methods for connecting with hardware, namely, four HCI transmission layers: USB, RS232, UART and PC card.
其中，controller定义了底层硬件部分，包括无线射频(RF)、基带(BB)和链路管理(LM)，RF层通过2.4GHz无需授权的ISM频段的微波，实现数据位流的过滤和传输，主要定义了蓝牙收发器在此频带正常工作所需要满足的条件。基带负责跳频以及蓝牙数据和信息帧的传输。链路管理负责连接、建立和拆除链路并进行安全控制。链路管理(link  manager，LM)层是蓝牙协议栈的链路管理层协议,负责将上层HCI命令翻译成基带能接受的操作,建立异步链路(asynchronous connection-oriented link，ACL)和同步链路(synchronous connection-oriented/extended，SCO)以及使蓝牙设备进入节能状态的工作模式等。链路控制(link control，LC)层负责在一批数据包传送期间，响应上层LM命令(如执行建立数据包的传输链路,维持链路等功能的LM命令)。Among them, the controller defines the underlying hardware, including radio frequency (RF), baseband (BB), and link management (LM). The RF layer uses the 2.4GHz unlicensed ISM band microwave to achieve data bit stream filtering and transmission. It mainly defines the conditions that the Bluetooth transceiver needs to meet in this frequency band. The baseband is responsible for frequency hopping and the transmission of Bluetooth data and information frames. Link management is responsible for connecting, establishing and dismantling links and performing security control. The link manager (LM) layer is the link management layer protocol of the Bluetooth protocol stack, which is responsible for translating the upper-layer HCI commands into operations that the baseband can accept, and establishing asynchronous connection-oriented link (ACL) and synchronous links Road (synchronous connection-oriented/extended, SCO) and working modes that enable Bluetooth devices to enter an energy-saving state, etc. The link control (LC) layer is responsible for responding to upper-layer LM commands (such as executing LM commands for establishing the transmission link of the data packet and maintaining the link) during the transmission of a batch of data packets.

Elaboration.
图4示出了一种被连接设备中配置的扫描参数的示意图。被连接设备通常不知道何时有设备来连接，所以一般会被配置成典型的扫描参数。其中，寻呼扫描间隔(page scan interval)和寻呼扫描窗口(page scan window)为2个扫描参数，被连接设备在进行扫描搜索时的占空比如公式(1)所示：Figure 4 shows a schematic diagram of scanning parameters configured in a connected device. The connected device usually does not know when there is a device to connect, so it is usually configured with typical scan parameters. Among them, the page scan interval (page scan interval) and the page scan window (page scan window) are two scan parameters, and the duty cycle of the connected device during scan search is as shown in formula (1):
Figure PCTCN2020113554-appb-000003
Figure PCTCN2020113554-appb-000003
占空比其实表示在一个寻呼扫描间隔内被连接设备进行寻呼扫描的时间占比。这个比例越大，则被连接设备越容易被扫描到；但是这个比例越大，被连接设备的功耗也会同时相应的增加。The duty cycle actually represents the percentage of time that the connected device performs page scanning in a page scanning interval. The larger the ratio, the easier it is for the connected device to be scanned; but the larger the ratio, the power consumption of the connected device will increase accordingly.
目前，被连接设备的占空比配置不灵活，对于所有的场景都配置一样的占空比，不能满足不同场景下用户的需求。Currently, the duty cycle configuration of the connected device is not flexible, and the same duty cycle is configured for all scenarios, which cannot meet the needs of users in different scenarios.
本申请实施例中，被连接设备通过场景识别，可以改变蓝牙连接参数(例如，page scan interval和/或page scan window)，达到灵活配置占空比的目的。示例性的，对于手机灭屏状态，手机可以配置较低的占空比，这样可以达到节省功耗的目的；对于手机来电等用户希望尽快连接蓝牙耳机的场景，可以配置较高的占空比，从而可以降低手机和蓝牙耳机之间进行蓝牙连接的时延。In this embodiment of the application, the connected device can change the Bluetooth connection parameters (for example, page scan interval and/or page scan window) through scene recognition, so as to achieve the purpose of flexibly configuring the duty cycle. Exemplarily, for the mobile phone screen off state, the mobile phone can be configured with a lower duty cycle, which can achieve the purpose of saving power consumption; for scenarios where the user wants to connect to the Bluetooth headset as soon as possible, such as a mobile phone call, a higher duty cycle can be configured , Which can reduce the delay of Bluetooth connection between the mobile phone and the Bluetooth headset.
下面以被连接设备为手机为例进行说明。手机在处于某一个场景(例如，手机来电)下时，手机等待蓝牙耳机连接。现有的蓝牙耳机连接手机时，需要用户打开耳机盒，耳机 针对手机的MAC地址发起寻呼消息，从而和手机相连。现有的连接方式中，手机进行寻呼扫描(page scan)时，其占空比是固定不变的。但是在某些场景下，用户其实希望蓝牙耳机尽快连接上手机，占空比固定不变可能会造成蓝牙耳机连接手机的速度过慢，从而影响用户的体验。本申请实施例中，对于不同的场景可以配置不同的占空比，有助于提高配件设备连接手机的速度。The following is an example of the connected device being a mobile phone. When the mobile phone is in a certain scene (for example, a mobile phone call), the mobile phone waits for the Bluetooth headset to connect. When an existing Bluetooth headset is connected to a mobile phone, the user needs to open the headset box, and the headset initiates a paging message to the MAC address of the mobile phone to connect to the mobile phone. In the existing connection mode, when the mobile phone performs page scan, its duty cycle is fixed. However, in some scenarios, users actually hope that the Bluetooth headset is connected to the mobile phone as soon as possible. A fixed duty cycle may cause the Bluetooth headset to connect to the mobile phone too slowly, thereby affecting the user's experience. In the embodiments of the present application, different duty cycles can be configured for different scenarios, which helps to increase the speed of the accessory device connecting to the mobile phone.
示例性的，表1示出了一种场景与扫描参数的映射关系。Exemplarily, Table 1 shows a mapping relationship between a scene and a scan parameter.

下面结合具体场景对本申请实施例中的蓝牙连接的方法进行说明。The Bluetooth connection method in the embodiment of the present application will be described below in conjunction with specific scenarios.
图6示出了本申请实施例中的蓝牙连接方法600的示意性流程图。如图6所示，该方法600包括：FIG. 6 shows a schematic flowchart of a Bluetooth connection method 600 in an embodiment of the present application. As shown in FIG. 6, the method 600 includes:
S601，手机检测到来电事件。S601: The mobile phone detects an incoming call event.
S602，手机根据映射关系查找对应的扫描参数，其中，扫描参数包括page scan interval和page scan window。S602: The mobile phone searches for corresponding scan parameters according to the mapping relationship, where the scan parameters include page scan interval and page scan window.
示例性的，如表1所示，当手机检测到来电事件时，可以确定扫描参数中page scan interval为640ms，page scan window为22.5mss。Exemplarily, as shown in Table 1, when the mobile phone detects an incoming call event, it can be determined that the page scan interval in the scan parameters is 640 ms, and the page scan window is 22.5 mss.
S603，蓝牙耳机检测到用户打开耳机盒的操作。S603: The Bluetooth headset detects the user's operation to open the headset box.
S604，响应于该操作，蓝牙耳机针对手机的MAC地址发起寻呼(page)。S604: In response to the operation, the Bluetooth headset initiates a page for the MAC address of the mobile phone.
应理解，方法600中假设蓝牙耳机上一次连接的设备为手机，那么蓝牙耳机在检测到用户开盒后，就可以针对手机的MAC地址发起page。It should be understood that the method 600 assumes that the last connected device of the Bluetooth headset is a mobile phone, and after detecting that the user has opened the box, the Bluetooth headset can initiate a page for the MAC address of the mobile phone.
S605，手机和蓝牙耳机进行标准蓝牙配对过程。S605, the mobile phone and the Bluetooth headset perform a standard Bluetooth pairing process.
S606，手机和蓝牙耳机之间建立HFP连接。In S606, an HFP connection is established between the mobile phone and the Bluetooth headset.
示例性的，当手机通过蓝牙耳机接听电话时，手机和蓝牙耳机之间可以进行HFP连接。Exemplarily, when the mobile phone answers a call through the Bluetooth headset, an HFP connection can be made between the mobile phone and the Bluetooth headset.
S607，当手机和蓝牙耳机建立了蓝牙连接时，手机可以根据该映射关系查找对应的扫描参数。S607: When a Bluetooth connection is established between the mobile phone and the Bluetooth headset, the mobile phone can search for corresponding scanning parameters according to the mapping relationship.
示例性的，如表1所示，当手机已连接蓝牙设备工作时，可以确定扫描参数中page scan interval为1280ms，page scan window为11.25ms。Exemplarily, as shown in Table 1, when the mobile phone is connected to a Bluetooth device to work, it can be determined that the page scan interval in the scan parameters is 1280 ms, and the page scan window is 11.25 ms.
应理解，手机还可以为不同的场景设置不同的定时时长。例如，对于手机检测到来电事件，手机可以配置较高的占空比；但是如果在该来电事件对应的定时时长内，手机没有与任何蓝牙设备建立蓝牙连接，那么手机可以配置较低的占空比。It should be understood that the mobile phone can also set different timing durations for different scenarios. For example, for a mobile phone to detect an incoming call event, the mobile phone can be configured with a higher duty cycle; but if the mobile phone does not establish a Bluetooth connection with any Bluetooth device within the timing period corresponding to the incoming call event, then the mobile phone can be configured with a lower duty cycle ratio.

手机在确定用户打开蓝牙开关或者进入蓝牙设备界面时，可以判断用户希望经蓝牙设 备与手机相连，那么手机可以配置较高的占空比，从而降低蓝牙耳机与手机建立蓝牙连接的时延。When the mobile phone determines that the user turns on the Bluetooth switch or enters the Bluetooth device interface, it can determine that the user wants to connect to the mobile phone via the Bluetooth device, then the mobile phone can be configured with a higher duty cycle, thereby reducing the time delay for the Bluetooth headset to establish a Bluetooth connection with the mobile phone.
S703，手机从检测到用户打开蓝牙开关或者进入蓝牙设置界面开始的预设时间段内，手机没有和任何蓝牙设备建立蓝牙连接，此时手机可以变更扫描参数。S703: The mobile phone has not established a Bluetooth connection with any Bluetooth device within a preset period of time since the mobile phone detects that the user turns on the Bluetooth switch or enters the Bluetooth setting interface. At this time, the mobile phone can change the scanning parameters.
示例性的，从手机检测到用户打开蓝牙开关起10s内，手机没有检测到用户连接任何蓝牙设备且手机还处于亮屏状态时，此时手机可以确定扫描参数中page scan interval为640ms，page scan window为11.25ms。Exemplarily, within 10 seconds after the mobile phone detects that the user turns on the Bluetooth switch, the mobile phone does not detect that the user is connected to any Bluetooth device and the mobile phone is still on the screen. At this time, the mobile phone can determine that the page scan interval in the scan parameters is 640 ms, page scan The window is 11.25ms.

At this time, the mobile phone can determine that the page scan interval in the scan parameters is 1280 ms, page scan The window is 11.25ms.
本申请实施例中，当手机预判用户希望手机和蓝牙耳机建立连接时，可以配置较高的占空比，从而降低手机和蓝牙耳机的连接的时延；但是当在预设时间内，手机预判的事件并没有发生，那么此时手机可以将占空比调低，从而避免浪费手机的功耗。In the embodiment of this application, when the mobile phone predicts that the user wants the mobile phone to establish a connection with the Bluetooth headset, a higher duty cycle can be configured to reduce the time delay of the connection between the mobile phone and the Bluetooth headset; The predicted event did not happen, so the mobile phone can reduce the duty cycle at this time to avoid wasting the power consumption of the mobile phone.
本申请实施例中，被连接设备通过场景识别，可以改变蓝牙连接参数(例如，page scan interval和/或page scan window)，达到灵活配置占空比的目的。这样在一些特殊场景(例如，手机来电时)下，可以提升被连接设备和蓝牙设备的连接速度；同时在一些普通场景下(例如，手机灭屏或者手机已经和蓝牙耳机建立蓝牙连接)，可以节省被连接设备的功耗。In this embodiment of the application, the connected device can change the Bluetooth connection parameters (for example, page scan interval and/or page scan window) through scene recognition, so as to achieve the purpose of flexibly configuring the duty cycle. In this way, in some special scenarios (for example, when a mobile phone calls), the connection speed between the connected device and the Bluetooth device can be increased; at the same time in some common scenarios (for example, the mobile phone screen is off or the mobile phone has established a Bluetooth connection with the Bluetooth headset), you can Save the power consumption of the connected device.
以上以手机为例，手机作为被连接设备时，可以配置不同场景下不同的扫描参数。下面以配件设备(例如，蓝牙耳机)为例进行说明。蓝牙耳机也可以根据不同的场景配置不同的扫描参数。蓝牙耳机在处于某一个场景(例如，手机来电)下时，希望提高双耳连接的速度。现有的蓝牙耳机连接手机时，需要用户打开耳机盒，一只耳机可以向另一只耳机发起寻呼。现有的连接方式中，另一只耳机进行寻呼扫描(page scan)时，其占空比是固定不变的。但是在某些场景下，用户其实希望双耳连接的速度，占空比固定不变可能会造成双耳连接的速度过慢，从而影响用户的体验。本申请实施例中，对于不同的场景可以配置不同的占空比，有助于提高双耳连接的速度以及其他设备连接配件设备的速度。Taking the mobile phone as an example above, when the mobile phone is used as a connected device, different scanning parameters can be configured in different scenarios. The following takes an accessory device (for example, a Bluetooth headset) as an example for description. The Bluetooth headset can also be configured with different scanning parameters according to different scenarios. When the Bluetooth headset is in a certain scene (for example, a mobile phone call), it is hoped to increase the speed of the binaural connection. When an existing Bluetooth headset is connected to a mobile phone, the user needs to open the headset box, and one headset can initiate a paging to the other headset. In the existing connection method, when another headset performs page scan, its duty cycle is fixed. However, in some scenarios, users actually want the speed of the binaural connection, and a fixed duty cycle may cause the speed of the binaural connection to be too slow, thereby affecting the user's experience. In the embodiments of the present application, different duty cycles can be configured for different scenarios, which helps to increase the speed of the binaural connection and the speed of other devices connecting to accessory devices.
示例性的，表5示出了另一种场景与扫描参数的映射关系。Exemplarily, Table 5 shows the mapping relationship between another scene and scan parameters.

应理解，蓝牙耳机作为被连接设备时，蓝牙耳机配置不同的扫描参数的方式也可以参考上述表1至表4，即蓝牙耳机可以调整page scan interval和page scan window中的一个或者两个参数来调整占空比，这里为了简洁不在赘述。It should be understood that when a Bluetooth headset is used as a connected device, the manner in which the Bluetooth headset configures different scanning parameters can also refer to the above Table 1 to Table 4. That is, the Bluetooth headset can adjust one or two of the page scan interval and page scan window. To adjust the duty cycle, I won't repeat it here for brevity.
应理解，表4中有关page scan interval和page scan window的值仅仅是示意性的，本申请实施例对此并不作任何限定。It should be understood that the values of page scan interval and page scan window in Table 4 are only illustrative, and the embodiment of the present application does not impose any limitation on this.
下面结合具体场景对本申请实施例中的蓝牙连接的方法进行说明。The Bluetooth connection method in the embodiment of the present application will be described below in conjunction with specific scenarios.
图8示出了本申请实施例中的蓝牙连接方法800的示意性流程图。如图8所示，该方法800包括：FIG. 8 shows a schematic flowchart of a Bluetooth connection method 800 in an embodiment of the present application. As shown in FIG. 8, the method 800 includes:
S801，蓝牙耳机检测到用户打开耳机盒，且此时耳机盒中包括双耳。S801: The Bluetooth headset detects that the user has opened the headset box, and at this time, the headset box includes both ears.
S802，蓝牙耳机根据映射关系查找对应的扫描参数，其中，扫描参数包括page scan interval和page scan window。S802. The Bluetooth headset searches for corresponding scan parameters according to the mapping relationship, where the scan parameters include page scan interval and page scan window.
示例性的，如表5所示，当蓝牙耳机检测到双耳开盒时，如果双耳未连接，为达到快速实现双耳连接，可以确定page scan interval为48ms，page scan window为11.25ms。Exemplarily, as shown in Table 5, when the Bluetooth headset detects binaural open box, if both ears are not connected, in order to achieve fast binaural connection, it can be determined that the page scan interval is 48 ms and the page scan window is 11.25 ms.
应理解，此时蓝牙耳机配置较高占空比的目的可以是提高其他设备扫描到蓝牙耳机的速度，以及提高双耳连接的速度。同时，此时蓝牙耳机配置较高占空比可以使得其他设备(除上次连接的设备以外的设备)扫描到蓝牙耳机的速度。It should be understood that the purpose of configuring a higher duty cycle for the Bluetooth headset at this time may be to increase the speed of other devices scanning to the Bluetooth headset and increase the speed of the binaural connection. At the same time, when the Bluetooth headset is configured with a higher duty cycle, other devices (devices other than the device connected last time) can scan to the speed of the Bluetooth headset.
还应理解，在提高双耳连接的速度时，可以是主耳配置较高的占空比，副耳正常发送寻呼(page)，从而提高双耳连接的速度。It should also be understood that when increasing the speed of the binaural connection, the primary ear may be configured with a higher duty cycle, and the secondary ear normally sends a page, thereby increasing the speed of the binaural connection.
S803，当双耳连接后，蓝牙耳机可以根据映射关系变更到对应的扫描参数。S803: After the two ears are connected, the Bluetooth headset can be changed to the corresponding scanning parameter according to the mapping relationship.
示例性的，如表5所示，当双耳已经连接时，蓝牙耳机可以确定page scan interval为640ms，page scan window为11.25ms。Exemplarily, as shown in Table 5, when both ears are connected, the Bluetooth headset can determine that the page scan interval is 640 ms and the page scan window is 11.25 ms.

示例性的，手机和蓝牙耳机建立蓝牙连接后，蓝牙耳机可以确定page scan interval为1280ms，page scan window为11.25ms。此时，较低的占空比有助于节省手机的功耗。Exemplarily, after the Bluetooth connection between the mobile phone and the Bluetooth headset is established, the Bluetooth headset can determine that the page scan interval is 1280 ms and the page scan window is 11.25 ms. At this time, a lower duty cycle helps to save the power consumption of the mobile phone.
一个实施例中，蓝牙耳机还可以配置不同场景下的定时时长。例如，蓝牙耳机检测到双耳开盒的操作后，可以确定page scan interval为48ms，page scan window为11.25ms。当双耳连接上后，蓝牙耳机可以确定page scan interval为640ms，page scan window为11.25ms。若从双耳连接上开始的定时时长内，蓝牙耳机没有和上一次连接的设备建立蓝牙连接，那么蓝牙耳机可以调整扫描参数，例如，蓝牙耳机从双耳连接上5s内没有和上一次连接的手机建立蓝牙连接，那么手机可以确定page scan interval为1280ms，page scan window为11.25ms。In an embodiment, the Bluetooth headset can also be configured with timing durations in different scenarios. For example, after a Bluetooth headset detects a binaural box opening operation, it can be determined that the page scan interval is 48 ms and the page scan window is 11.25 ms. When both ears are connected, the Bluetooth headset can determine that the page scan interval is 640ms and the page scan window is 11.25ms. If the Bluetooth headset does not establish a Bluetooth connection with the last connected device within the time period from the binaural connection, then the Bluetooth headset can adjust the scanning parameters. For example, the Bluetooth headset has not been connected to the last connected device within 5 seconds from the binaural connection If the mobile phone establishes a Bluetooth connection, the mobile phone can determine that the page scan interval is 1280ms and the page scan window is 11.25ms.
一个实施例中，若蓝牙耳机检测到单耳开盒时，可以根据映射关系确定page scan interval为320ms，page scan window为11.25ms，此时蓝牙耳机可以认为另一个耳机正在进行工作，用户可能想拿出来另一支耳机听歌或者接听电话。In one embodiment, if the Bluetooth headset detects that the single-ear box is opened, the page scan interval can be determined to be 320ms and the page scan window is 11.25ms according to the mapping relationship. At this time, the Bluetooth headset can think that the other headset is working, and the user may want to Take out another headset to listen to a song or answer a call.
一个实施例中，若双耳连接过程中发生中断，例如，左耳和右耳之间的距离过远导致双耳发生中断。此时蓝牙耳机可以确定page scan interval为320ms，page scan window为11.25ms。此时配置较高占空比的目的是为了提升双耳重新建立连接的速度。In one embodiment, if an interruption occurs during the connection between the two ears, for example, the distance between the left ear and the right ear is too far, causing the two ears to be interrupted. At this time, the Bluetooth headset can determine that the page scan interval is 320ms and the page scan window is 11.25ms. The purpose of configuring a higher duty cycle at this time is to increase the speed of re-establishing the connection between the ears.

本申请实施例中，蓝牙耳机确定用户按压耳机盒上的功能键进入强制配对状态时，可以提升查询扫描(page scan)过程中的占空比,这样可以提升其他设备查询到蓝牙耳机的速度，从而可以使得蓝牙耳机和其他设备尽快建立蓝牙连接。In the embodiment of the present application, when the Bluetooth headset determines that the user presses the function key on the headset box to enter the forced pairing state, the duty cycle in the page scan process can be increased, which can increase the speed at which other devices can query the Bluetooth headset. Thereby, the Bluetooth headset and other devices can establish a Bluetooth connection as soon as possible.

在蓝牙耳机和手机A建立蓝牙连接后，蓝牙耳机配置了较低的占空比。那么当手机B检测到来电事件时，用户其实希望手机B尽快和蓝牙耳机相连，但是蓝牙耳机此时又处于一个较低占空比的状态，会影响手机B和蓝牙耳机连接的速度。那么手机B此时可以通过手机A通知蓝牙耳机提升占空比。After the Bluetooth headset and mobile phone A establish a Bluetooth connection, the Bluetooth headset is configured with a lower duty cycle. Then when mobile phone B detects an incoming call event, the user actually wants mobile phone B to be connected to the Bluetooth headset as soon as possible, but the Bluetooth headset is in a lower duty cycle state at this time, which will affect the connection speed of mobile phone B and the Bluetooth headset. Then the mobile phone B can notify the Bluetooth headset to increase the duty cycle through the mobile phone A at this time.
