Description

一种通信方法及移动终端 技术领域
本发明涉及通信领域，尤其涉及一种蓝牙设备的通信方法和相关的蓝牙设备。
背景技术
随着科技发展，蓝牙产品越来越多地出现在人们的生活中。如图1A和1B所示，为常见的蓝牙设备使用场景图。如图2所示，为现在主流的WiFi/BT(Bluetooth，蓝牙)二合一模块的前端方案。从图中可以看出，在芯片在产品实际使用中，出于排除干扰的考虑，BT芯片前端增加有SAW(surface acoustic wave，声表滤波)器件。在模块内部还有用来切换发射或接收的SPDT(Single-Pole Double-Throw，单刀双掷)开关，加上线路板走线损耗，实际蓝牙功能模块中的IPA(internal Power Amplifier，内置功率放大器)发出的功率到达终端产品天线口时，发射功率已降低，导致蓝牙的通信距离减少。目前BT芯片的发射功率在10dBm左右，有一些可达13dBm-14dBm。在满足BT发射功率规范要求的情况下，为了增加BT的通信距离，则需要尽可能提高终端产品天线口的BT发射功率。如图3A所示，为现有技术中WiFi/BT二合一模块工作在WiFi模式下或BT接收模式下的示意图。如图3B所示，为现有技术中的一种提供天线口BT发射功率的方案。具体的是在BT芯片外部增加外置PA(Power Amplifier,功率放大器),即EPA(External Power Amplifier，外置功率放大器)，从而提高产品天线口的发射功率，增加通信距离。图3B所示的方案中，蓝牙的最大发射功率由EPA与IPA级联实现，其中IPA作为EPA的输入级给EPA提供激励信号，EPA输出的发射功率即蓝牙的发射功率。上述方案有效地提高了BT的发射功率，然而在该方案中，由于IPA和EPA同时工作，增加了系统的耗电，导致产品工作时间缩短。同时，如果IPA发射功率比较大，则会导致EPA的输出功率饱和，从而引起产品发射指标异常，影响通信质量。

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，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
为解决现有技术中设置了外置功率放大器的蓝牙产品发射功率过高导致的功耗较高以及可能导致的蓝牙发射功率饱和的问题，本发明实施例提出了一种解决方案，用以调整蓝牙产品的发射功率。本发明实施例在如图3A和图3B所示的蓝牙设备结构示意图上进行改进，如图4所示，为蓝牙设备提供两种发射链路，使得蓝牙设备可以根据实际情况进行发射功率的调整，在保证蓝牙发射功率的情况下，延长蓝牙设备的工作时间。
如图4所示，为本发明实施例提供的蓝牙设备的结构示意图。在该实施例中，蓝牙设备设置有两条发射链路，分别为第一发射链路和第二发射链路。从图中可以看出，第一发射链路由蓝牙芯片内置功率放大器实现蓝牙发射功率的放大，而第二发射链路由蓝牙芯片内置功率放大器加外置功率放大器实现蓝牙发射功率的放大。
下面结合图5-图7具体说明本发明实施例提供的蓝牙设备的通信方法。
如图5所示，为本发明实施例提供的一种蓝牙设备的通信方法。
步骤501，蓝牙设备获取接收的信号强度指示RSSI；
步骤502，将获取到的RSSI与预设的值进行比较；
该预设的值根据产品的实际需求距离确定，在实际实现中，该预设的值也与天线质量有关。一个可能的情况是，该预设的值包括两个，分别为第一门限值和第二门限值，例如，该预设的值为-70，-65。
步骤503，根据比较结果确定蓝牙发射链路；

步骤504，根据确定的蓝牙发射链路进行蓝牙信号发射。
上述实施例提供的蓝牙通信方法，通过为蓝牙设备提供两种发射链路，使得蓝牙设备可以根据实际情况进行发射功率的调整，在保证蓝牙发射功率的情况下，延长蓝牙设备的工作时间。
如图6所示，为本发明实施例提供的一种蓝牙设备的通信方法。
步骤601，蓝牙设备获取接收的信号强度指示RSSI；
步骤602，将获取到的RSSI与预设的值进行比较，如果RSSI大于第一门限值，则转到步骤603，如果RSSI小于第二门限值，则转到步骤604；
步骤603，确定蓝牙发射链路为第一发射链路；蓝牙设备通过所述第一发射链路进行蓝牙信号的发射。
步骤604，确定蓝牙发射链路为第二发射链路；蓝牙设备通过所述第二发射链路进行蓝牙信号的发射。
上述实施例提供的蓝牙通信方法，通过为蓝牙设备提供两种发射链路，使得蓝牙设备可以根据实际情况进行发射功率的调整，在保证蓝牙发射功率的情况下，延长蓝牙设备的工作时间。
如图7所示，为本发明实施例提供的一种蓝牙设备的通信方法。在该实施例中，涉及蓝牙的功率控制表。蓝牙功率控制表记录蓝牙功率等级与输出功率的关系，用于控制蓝牙的输出功率。
步骤701，蓝牙设备获取接收的信号强度指示RSSI；
步骤702，将获取到的RSSI与预设的值进行比较，如果RSSI大于第一门限值，则转到步骤703，如果RSSI小于第二门限值，则转到步骤704；
所述蓝牙发射链路包括第一发射链路和第二发射链路。如图4所示，所述第一发射链路为蓝牙模块内置功率放大器发射链路，所述第二发射链路为蓝牙模块内置功率放大器加蓝牙模块外置功率放大器发射链路。通常情况下，当获取的RSSI值比较小时，例如，小于第一门限值，说明此时蓝牙信号不太好，需要将蓝牙发射功率到比较大，由于第二发射链路发射的功率比较大，此时会确定蓝牙发射链路为第二发射链路，反之，当获取的RSSI值比较大时，例如，大于第一门限值，说明此时蓝牙信号较好，不需要较大的发射功率，此时会确定蓝牙发射链路为第一发射链路，即蓝牙模块内置功率放大器发射链路。
步骤703，确定蓝牙发射链路为第一发射链路；蓝牙设备通过所述第一发射链路进行蓝牙信号的发射。在确定蓝牙发射链路为第一发射链路后，所述方法还包括步骤705，将蓝牙芯片的功率控制表调整到高增益等级。
在现有技术中，示例性的，蓝牙功率控制表一个可能的表现方式如下表1所示：
增益等级 IPA输出功率 总输出
0 -6 -6
1 -4 -4
2 -2 -2
3 0 0
4 2 2
5 4 4
6 6 6
表1
或者，蓝牙功率控制表一个可能的表现方式如下表2所示：
增益等级 IPA+EPA输出功率 总输出
0 16 16
1 18 18
2 20 20
3 22 22
4 24 24
5 26 26
6 28 28
表2
从上表可以看出，现有技术中IPA+EPA的输出功率比较大，增益等级越大，输出功率越大，越有可能导致蓝牙设备的输出功率饱和，从而引起产品发射指标异常，影响通信质量。
在本发明实施例中，对上述蓝牙控制表进行了改进，改进后的蓝牙控制表示例性的可以为：
增益等级 IPA输出功率 IPA+EPA 总输出
0 -10 12 12
1 -8 14 14
2 -6   -6
3 -4   -4
4 -2   -2
5 0   0
6 2   2
7 4   4
8 6   6
表3
从表3可以看出，在该表中，增加了两个输出等级，原最低的两个输出等级0、1中，IPA的输出功率也相对较低。
在本实施例中，在确定蓝牙发射链路为第一发射链路后，将蓝牙芯片的功率控制表调整到高增益等级，示例性的，高增益等级可以为2以上的等级，此时，IPA的输出功 率较高，能保证蓝牙设备的通信质量，同时蓝牙设备的功耗相对较低。
步骤704，确定蓝牙发射链路为第二发射链路；蓝牙设备通过所述第二发射链路进行蓝牙信号的发射。在确定蓝牙发射链路为第二发射链路后，所述方法还包括步骤706，将蓝牙芯片的功率控制表调整到低增益等级。
如上表3所示，在确定蓝牙发射链路为第一发射链路后，将蓝牙芯片的功率控制表调整到低增益等级，示例性的，低增益等级可以为0、1级，此时，IPA+EPA的输出功率较高，同时蓝牙设备的输出功率不会饱和而引起产品发射指标异常，影响通信质量。
上述实施例提供的蓝牙通信方法，为蓝牙设备提供两种发射链路，同时对蓝牙设备的功率控制表进行改进，使得蓝牙设备可以根据实际情况进行发射功率的调整，在保证蓝牙发射功率的情况下，延长蓝牙设备的工作时间。
