Description

数据发送方法、装置和终端 技术领域
本发明涉及无线通信领域，尤其涉及数据发送方法、装置和终端。
背景技术
随着无线通信技术的发展，提供蓝牙通信功能的终端逐渐普及，比如戴式终端、手机、车载终端等大多提供蓝牙通信功能。相对于传统蓝牙协议，新的蓝牙低功耗(Bluetooth Low Energy，BLE)协议的制定为功耗要求较高的终端产品提供了有效的解决方案。BLE协议和传统蓝牙协议在协议内容和实现方式上面都是独立的。一般来说，BLE协议适用于终端传输的数据量不大的情况，比如只传输几个字节的控制命令等，这种情况下对终端的传输速率要求不高。而当终端传输的数据量较大时，例如要从手机端向手环产品传送一个手环的升级包，这种情况下对终端的传输速率要求较高，对于这类速率敏感的业务来说，采用BLE协议极大地降低了用户体验。
为了在降低终端功耗的前提下，有效的提高数据传输速率，现有技术的数据发送方法中采用了如下的解决方案：当采用BLE协议进行数据传输时，在一个连接事件间隔(connection event interval)里进行一定数目的报文(packet)的发送。例如，在图1所示的一个典型的应用场景中，应用程序(Application，APP)基于逻辑链路控制和适配协议(Logical Link Control and Adaptation Protocol，L2CAP)不断的将用户数据(Data)发送给链路层(Link Layer，LL)，假设一个Data需要分为8个LL数据报(LL_Data)进行传输，图1中展示的3个Data需要24个LL_Data进行传输，一个connection event interval传输6个LL_Data，即进行6次报文(packet)的 交互，整个过程需要经历4个connection event interval。
由上可见，现有技术的数据发送方法中，数据不断的发送给LL，但LL在一个connection event interval里面只进行了少量的数据传输，例如，图1中只进行了6次，这样导致大量的空口资源被浪费掉，平均的传输速率低下，无法有效的提高数据传输速率，从而导致用户体验差，甚至导致一些业务无法正常进行。
发明内容
本发明实施例提供了数据发送方法、装置和终端，能够在降低终端功耗的前提下，有效的提高数据传输速率。
一方面，提供了一种数据发送方法，该方法中不是采用固定的数据发送模式，而是当采用BLE协议进行数据传输业务时，根据该业务的业务类型和/或用户指示，确定进行该数据传输业务的数据发送模式，采用确定出的数据发送模式进行该数据传输业务。通过该方法可以根据数据传输业务的紧急程度，灵活选取高速的数据发送模式或者低速的数据发送模式，从而达到降低终端功耗与提高数据传输速率之间的有效平衡。
在一个可能的设计中，当业务的业务类型和/或用户指示标识出该业务属于紧急业务时，确定进行数据传输业务的数据发送模式为第一发送模式，其中，第一发送模式为在每个连接事件间隔内持续发送报文的数据发送模式，连接事件间隔为两个连接事件之间的时间间隔。其中，连接事件间隔以1.25ms为单位，连接事件间隔的值为6至3200，即一个连接事件间隔为7.5ms至4s的时间。
在一个可能的设计中，当确定出进行数据传输业务的数据发送模式为上述第一发送模式时，在每个连接事件间隔内，判断当前是否有数据报文要发送；若判断出当前有数据报文要发送，则发送数据报文；若判断出当前没有数据报文要发送，则发送空报文。这种在没有数据报文要发送时，发送空报 文的方式，可以确保在一个连接事件间隔内，当没有数据报文要发送时，终端不会进入休眠态，后续有数据报文要发送时，能够继续在该连接事件间隔内发送数据报文，而不必等到下一个连接事件间隔，从而有效利用了每个连接事件间隔内的传输时间，提高了数据传输速率。
在一个可能的设计中，当业务的业务类型和/或用户指示标识出该业务属于非紧急业务时，确定进行数据传输业务的数据发送模式为第二发送模式，第二发送模式为在每个连接事件间隔内发送预定数目个报文的数据发送模式，连接事件间隔为两个连接事件之间的时间间隔。
在一个可能的设计中，当确定出进行数据传输业务的数据发送模式为第二发送模式时，在每个连接事件间隔内，先判断在该连接事件间隔内发送的报文数目是否小于上述预定数目，当判断结果为当前发送的报文数目小于上述预定数目时，再判断当前是否有数据报文要发送；若判断出当前有数据报文要发送，则发送数据报文；若判断出当前没有数据报文要发送，则发送空报文。这种采用在每个连接事件间隔内发送固定数目个报文的数据发送模式可以有效降低功耗。
在一个可能的设计中，当确定出进行数据传输业务的数据发送模式为第二发送模式时，在每个连接事件间隔内，确定当前发送的报文数目小于上述预定数目；判断当前是否有数据报文要发送；若判断出当前有数据报文要发送，则发送数据报文；若判断出当前没有数据报文要发送，则在该连接事件间隔内停止发送报文。这种数据发送模式相当于设定了在每个连接事件间隔内能够发送的最大报文数目，当没有数据报文要发送时，停止发送报文，能够进一步有效降低功耗。
在一个可能的设计中，当业务的业务类型和/或用户指示标识出该业务属于非紧急业务时，确定进行数据传输业务的数据发送模式为第三发送模式，第三发送模式为在每个连接事件间隔内持续发送数据报文的数据发送模式，连接事件间隔为两个连接事件之间的时间间隔。这种数据发送模式在每个连 接事件间隔内发送报文的数目不固定，也未设定最大报文发送数目，数据传输速率较第二发送模式快，但是由于只传输数据报文，因此在当前没有数据报文时，终端会进入休眠态，数据传输速率不如第一发送模式快。
在一个可能的设计中，当确定出进行数据传输业务的数据发送模式为第三发送模式时，在每个连接事件间隔内，判断当前是否有数据报文要发送；若判断出当前有数据报文要发送，则发送数据报文；若判断出当前没有数据报文要发送，则在该连接事件间隔内停止发送报文。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发 明实施例中的附图，对本发明实施例中的技术方案进行描述。
本发明实施例中，按照不同的业务需求优化BLE的传输速率，以提高用户体验。为了实现可以定制的灵活的速率调整方法，提出连接事件间隔内事件发送的三种模式。提供自动的和用户参与的速率设置机制。由于在两个BLE设备的连接中使用跳频机制，两个设备使用特定的信道收发数据，然后过一段时间后再使用新的信道，两个设备在信道切换后收发数据称之为连接事件。连接事件间隔就是两个连接事件之间的时间间隔，连接事件间隔以1.25ms为单位，连接事件间隔的值为6至3200，即一个连接事件间隔为7.5ms至4s的时间。
其中，将连接事件间隔内事件的发送分为三种模式：
第一发送模式为无限发送模式，即可以设置为无限发送连接事件，即使没有数据，也可以发送空报文，将包头中的MD标志位设置为1，用来表示后续还有数据要发送，从而为后续数据立即可以发送做准备，直到一个连接事件间隔被占满。
第二发送模式为固定发送模式，即设置连接事件间隔内发送固定次数的报文，限制每一个连接事件间隔内可以发送的数据。每个连接事件间隔中发送报文的次数不能大于该固定次数。
第三发送模式为尽力而为发送模式，即此时不设置连接事件间隔内发送的报文的次数。这种模式下只要BLE设备有数据,就不停的发送，直到连接事件间隔到期。与无限发送模式不同的是，当BLE设备没有数据时，不发送空报文，结束一个连接事件间隔内的事件发送，等待下一个连接事件间隔到来。
本发明实施例中，由于可能有多个业务需要并发处理，因此当有高优先级的业务时，例如，当采用BLE协议进行数据传输业务时，开始了采用传统蓝牙的传输模式之一基础速率(Basic Rate，BR)模式传输的业务，若预先配置采用BR模式进行数据传输的业务的优先级高于采用BLE协议进行数据传 输的业务，则立刻结束一个连接事件间隔内的事件发送，开始调用采用BR模式进行数据传输的业务。
图2为本发明实施例提供的数据发送方法流程图，该方法可以由支持BLE协议的终端执行，其中，该终端也可称为BLE设备，参照图2，该方法包括：
步骤201，当采用BLE协议进行数据传输业务时，判断该业务是否属于紧急业务。
其中，可以但不限于采用下面两种方式判断该业务是否属于紧急业务：根据该业务的业务类型，判断该业务是否属于紧急业务；或者，提示用户选择传输模式，根据用户选择的传输模式，判断该业务是否属于紧急业务。
本发明实施例中，可以预先设定紧急业务对应的至少一个业务类型，当识别出该业务的业务类型属于紧急业务对应的业务类型时，确定该业务属于紧急业务。其中，可以根据数据传输业务的名称，或者该业务传输的文件的名称及扩展名，或者该业务传输的数据包的包头中携带的业务类型字段，识别该业务的业务类型。
步骤202，当判断出该业务属于紧急业务时，判断当前发送模式是否为无限发送模式。
步骤203，若当前发送模式不为无限发送模式时，将当前发送模式设置为无限发送模式。
步骤204，在每个连接事件间隔内，判断当前是否有用户数据要发送。
步骤205，若判断出当前有用户数据要发送，则发送用户数据，并将数据包包头中的标志位设置为1，该标志位为1用于指示后续还有数据要发送。
步骤206，若判断出当前没有用户数据要发送，则发送空报文，并将包头中的标志位设置为1。
本发明实施例中，当数据传输业务完成时，可以将当前发送模式由无限发送模式恢复为预设发送模式。通常地，预设发送模式是针对非紧急业务设定的，因此包括固定发送模式和尽力而为发送模式两种。
此外，当步骤201中判断出该业务属于非紧急业务时，采用当前发送模式发送用户数据，此时无需重新设置发送模式。
其中，当前发送模式可能为无限发送模式、固定发送模式和尽力而为发送模式中的任意一种。
若当前发送模式为无限发送模式，则通过步骤204至步骤206的方法来发送用户数据。
为了更清楚地描述无限发送模式的处理过程，在本发明的一个具体的实施例中，采用图3所示的处理流程，参照图3，每个连接事件间隔开始前，均要判断是否为无限发送模式，避免一直采用无限发送模式而浪费不必要的功耗。
若当前发送模式为固定发送模式，则通过图4所示的数据发送方法来发送用户数据，参照图4，该方法包括：
步骤401，当当前发送模式为固定发送模式时，在每个连接事件间隔内，根据固定发送模式的固定发送次数判断每个连接事件间隔内剩余的发送次数是否大于1。
步骤402，当判断出剩余的发送次数大于1时，判断当前是否有用户数据要发送。
步骤403，若判断出当前有用户数据要发送，则发送用户数据，并将数据包包头中的标志位设置为1。
步骤404，若判断出当前没有用户数据要发送，则发送空报文，并将包头中的标志位设置为1。
可选地，该方法还包括：
步骤405，当判断出剩余的发送次数等于1时，判断当前是否有用户数据要发送；
步骤406，若判断出当前有用户数据要发送，则发送用户数据，并将数据包包头中的标志位设置为0，所述标志位为0用于指示后续没有数据要发送。
步骤407，若判断出当前没有用户数据要发送，则发送空报文，并将数据包包头中的标志位设置为0。
其中，可以采用其他的处理方式来代替步骤404的处理方式，比如发现没有用户数据要发送时，在最后一个数据报文的包头中将标志位设置为0，和/或，可以直接将本次connection event interval里面要发送的固定次数设置为0，这样可以省去发送空报文的动作。
若当前发送模式为尽力而为发送模式，则通过图5所示的数据发送方法来发送用户数据，参照图5，该方法包括：
步骤501，当当前发送模式为尽力而为发送模式时，在每个连接事件间隔内，根据尽力而为发送模式，判断当前是否有用户数据要发送。
步骤502，若判断出当前有用户数据要发送，则发送用户数据，并将数据包包头中的标志位设置为1。
步骤503，若判断出当前没有用户数据要发送，则等待下一个连接时间间隔。
在此需要说明，图5为处理概要图，图中椭圆形标注的部分表示只要后续还有数据发送就将设置MD＝1；如果后续没有数据要发送，那么最后一个数据的MD＝0。
本发明实施例提供了一种数据发送方法，当采用BLE协议进行数据传输业务时，通过判断该业务是否属于紧急业务，从而将属于紧急业务的业务，采用无限发送模式来发送数据，即使没有数据时，也要发送空报文，并将包头中的标志位设置为1，该标志位为1用于指示后续还有数据要发送，以便为后续数据立即可以发送做准备，直到一个连接事件间隔被占满，因此能够在降低终端功耗的前提下，有效的提高数据传输速率。
本发明实施例中，可以根据不同的业务类型，自动选择event发送模式，其中，event发送模式与数据发送模式含义等同，业务类型的划分可以由产品开发人员针对不同的产品需求进行适当的划分。例如，将业务划分为紧急业 务和非紧急业务。(1)紧急业务：升级包传输业务；自带APP预置配置文件传输业务；一般的数据文件大小大于5M的数据传输业务等。(2)非紧急业务：除了紧急业务之外的其它业务。
图6为本发明实施例提供的数据发送方法流程图，该方法中根据不同的业务类型，自动选择event发送模式，参照图6，以发送一个升级包为例，由于发送升级包为一个专用目的的数据传输，因此对传输速率要求较高。APP能够识别此种业务的业务类型，根据识别的业务类型，将该业务确认为紧急业务。针对此种业务，直接将发送模式设置为无限发送模式。等升级包传输完毕后，再恢复到之前的发送模式。其具体传输过程可以参照图7所示的传输过程示意图。
参照图7，其中给出了传输所需时间的一个计算公式：(24+1)*1.2slot(1slot＝0.625ms)＝18.75ms。该公式中24表示24个用户有效数据，1表示一个空报文。1.2slot表示发送一个数据(包括对方设备的应答确认消息)所需要的时间，0.625表示一个slot的时间长度(单位为ms)，这是一个概要计算公式，只是为了表明使用本发明之后取得的效果，实际当中可能因为产品的实现的不同，而产生不同的结果。图7仅展示了一个connection event interval里面就将数据发送完毕的情况。实际当中根据数据量的不同，可能需要多个connection event interval来完成数据的发送。图7中当数据发送完成，但connection event interval还没有到期时，会发送Empty报文给对方，直到该interval到期为止，但需要说明的是，如果当前模式已经改变为其他模式(比如尽力而为模式)，那么就会停止Empty报文(将当前Empty报文中的MD设置为0)的发送，而不必一直发送Empty报文。
图8为本发明实施例提供的数据发送方法流程图，该方法中用户可以根据业务需求，自行选择event发送模式，参照图8，本发明实施例提供接口供用户选择不同的发送模式，表现给用户选择时，可以只有高速模式和低速模式，内部映射到不同的发送模式上面，例如，当用户选择高速模式时，采用 无限发送模式发送数据，当用户选择低速模式时，采用当前发送模式发送数据，其中，当前发送模式可以为无限发送模式、固定发送模式、尽力而为发送模式中的任意一种。
根据蓝牙设备在网络中的角色可分为主设备(Master)和从设备(Slave)，上面描述的是Master发送数据给Slave的情况，但由Slave发送数据给Master的情况，只要Slave发送数据时使用不同的发送模式就可以实现同样的效果。
为了实现三种发送模式直接的切换，在此提出使用HCI命令的方式进行切换，当然也可以使用其他方式实现切换，本发明实施例对此不做具体限定。在本发明的一个具体的实施例中，使用厂商特定(Vendor-specific，VS)的调试命令HCI命令通知控制器(controller)进入某一种发送模式进行工作。通过HCI命令可以随时改变当前的发送模式，进入另一种发送模式。
作为例子，下面给出该VS命令的格式：
