Description

移动终端和切换天线的方法 技术领域
本公开涉及(但不限于)通信领域。
背景技术
在相关技术中，手机集成度越来越高，功能也越来越强大，以前的手机仅有通话发短信功能，发展到如今，数据业务，全球定位系统(Global Positioning System，简称为GPS)或无线保真(Wireless Fidelity，简称为WIFI)功能，照相功能等等。然而功能越多，对手机的功耗影响越严重。目前常用的都是锂离子充电电池，电流由1000mA至5000mA不等。如果功能不断地增加而不考虑功耗，则手机有效使用时间变短。消费者对于手机的电量不足会感到很烦恼，并且频繁充电还会损耗电池的寿命，降低手机使用的年限。
目前手机的天线方案都是单一的天线，这种天线是适合所有发射与接收频段的天线。这种天线没有分支结构，手机发射效率在30％左右。对于信号比较弱的地区，几乎都需要最大发射功率进行发射，手机耗电比较严重。手机里面最大的耗电部件是手机功放，如果能够有效地优化功放电流，则能够增加手机的续航能力，并延长手机的使用寿命。

根据上述技术方案，在移动终端中设置主天线和分支天线，主天线可以在多个频段上传输数据，而分支天线可以在某个特定频段上传输数据，并且在该特定频段上，使用分支天线比使用主天线传输效果更好。根据上述技术方案，移动终端可以在不同场景在多个天线(即，主天线和分支天线)之间进行选择，以期在传输效果和消耗终端电量之间达到平衡，解决相关技术中由于天线效率低导致的手机功耗大的问题。
可选地，主天线构造为在多个频段上传输数据，并且分支天线构造为在单一频段上传输数据。
可选地，分支天线包括分别对应于多个频段的多个分支天线。每个分支天线可以分别对应于某个特定的频段，即，与主天线相比，移动终端使用特定的分支天线在特定的频段传输数据时传输效果更好，同时移动终端的自身功耗或者电量也耗费较少。
可选地，处理器20还构造为响应于通信业务的发射功率高于第一预设值，将所述通信业务切换至分支天线。
可选地，处理器20还构造为响应于通信业务的接收灵敏度低于第二预设值，将所述通信业务切换至分支天线。响应于通信业务的接收灵敏度低于第二预设值，将所述通信业务切换至所述至少一个分支天线。
可选地，在包括多个分支天线的情况下，处理器20还构造为：确定主天线执行通信业务的工作频段；并且将通信业务由主天线切换至与所确定的工作频段对应的分支天线。
下面结合本公开实施例进行详细说明。
根据本公开实施例，通过切换手机天线来增加手机发射效率从而减小发射功率，以改善手机的功耗。
根据本公开实施例，首先调试出适合所有频段都的天线作为主天线，目前能达到30％左右的发射效率，随后通过增加天线分支结构 和匹配电路来使手机的每个频段的发射效率都能达到50％至60％。用户在偏远地区或者信号弱的地区打电话或者进行数据业务时需要实际输出的功率18dBm时，手机传导的功率需要23dBm；通过将手机的天线切换到特定的使用频段，使得效率增加，在同样需要输出18dBm时，手机只需要输出20dBm左右。手机降低3dBm的发射功率使得电流可以下降120mA左右。在接收方面，实际接收的功率在-103左右；通过切换天线提高了接收效率，可以增加到-105左右，从而提高手机的通信能力。
通过在单一的总天线的基础上增加与每个频段对应的分支天线与分支匹配结构，使得在特定的环境下使用单一频段时的发射与接收效率达到最大，以节约电流、降低手机功耗、增加手机的续航能力并提高手机的通信能力。这种方案需要为手机增加在不同场景下进行适当切换的天线弹脚与开关。
需要说明的是，下面的具体数值为举例说明，不局限于此。
第一步：当用户在正常使用过程中(待机)情况下，天线使用主天线结构，此时天线没有切换。
第二步：当用户在离基站比较远的偏远地区或者隧道里，这时候信号比较弱，用户打电话时发射功率提高到23dBm时(传导)。此时，系统会识别出一旦信号超过18dBm，就需要通过切换天线来提高效率。将天线切换到与当前使用的频段对应的天线分支结构，使得效率提高2.5dBm，即，功率回退到20.5dBm，功耗下降，通话时间延长，并且接收灵敏度提高，通话加强。
第三步：通话结束后，手机会适当的识别此时的信号强度，如果信号强度小于-100dBm左右，系统会继续保持将天线切换至分支天线。
第四步：当手机信号高于-100dBm时，系统会将天线切换到主天线上，以返回归到原始的待机状态。
本实施方式中提出了一种可以根据手机接收信号或者发射功率来自动在主天线与分支天线进行切换的结构，从而达到优化手机发射功率，降低功耗并增强接收灵敏度。
下面结合附图对本公开实施例进行详细的说明。
图2是根据本公开具体实施方式的分支天线降低发射功耗实施方案图。
如图2所示，当用户在打电话过程中，逐渐的进入基站信号比较弱的地区，这时候手机发射功率逐步的增加，功耗不断上升，一旦功率上升到18dBm时，手机的发射检测电路将发送信号给处理器，处理器通过通用输入/输出(GPIO)口进行天线分支切换，切换到当前使用的频段。手机切换到分支天线后，效率增加，原本需要23dBm发射的功率，切换后功率降低到20.5dBm，功耗降低。
当用户电话结束后，系统会根据环境信号进行检验，当所在的频段信号功率小于-100dBm时，接收探测信号会通过射频收发芯片传递到处理器，处理器会通过GPIO口将主天线分支切换到分支天线上，用于增强信号的接收灵敏度。如果所处在的环境信号频段功率大于-100dBm，则此时天线不进行分支切换，天线处在主天线位置。
图3是根据本公开具体实施方式的分支天线框架部分三维模型图，图中示出了多个开关301，两侧的分支天线302和主天线303。
图4是根据本公开具体实施方式的手机整体三维结构天线分频实施方案示意图，图中示出了多个开关301，两侧的分支天线302，主天线303，处理器CPU 401和分支匹配处理部件402。
图5是根据本公开具体实施方式的手机分支天线实施方案二维模型图，图中示出了多个开关301，两侧的分支天线302，主天线303，处理器CPU401和分支匹配处理部件402。
采用上述方案，当正常使用(待机)时，手机的功放可以关闭，天线使用单一的主天线；当在隧道里或者比较偏僻的地方(离基站比较远)时，手机检测到信号强度低于-100dBm，并立即启动天线的切换，将手机切换到与正在使用的频段对应的分支天线，使手机接收灵敏度增强。当在强信号环境下通话时，手机是保持工作在主天线上，一旦进入隧道(例如，开车通过隧道)时，手机信号立即降低，且发射功率立即上升，使得功耗增加。此时，手机检测到发射功率超过18dBm，并启动天线的切换，将天线切换到与正在使用的频段对应的 分支天线，使效率上升，发射功率由原来的23dBm下降到20.5dBm左右，接收灵敏度上升2.5dBm左右，功耗降低，通话时间增加。
需要补充的是，作为对于上述技术方案的代替方案，可以在每个频段使用单独的分支天线，而不存在覆盖多个频段的主天线，使得手机总能具有最高的发射效率与最强的接收灵敏度。
