背景技术
目前，智能手机上的GNSS(Global Navigation Satellite System，全球导航卫星系统)定位功能成了智能手机的标准配置。现有智能手机中的GNSS定位系统有一个特点：当智能手机的上层应用以“高精度”或者“仅限设备”模式启动GNSS定位系统后，智能手机上的GNSS芯片处理模块在不确定当前环境中是否存在有卫星信号时会不停的扫描并试图捕获卫星信号。

具体实施方式
应当理解，此处所描述的实施例仅为了说明本发明，并不用于限定本发明。
参照图1，图1为本发明GNSS定位系统第一实施例的结构框架示意图，如图1所示，本发明实施例提出一种GNSS定位系统，应用于手机等移动通信终端，所述GNSS定位系统包括：卫星信号接收天线系统101、ELNA模块102、GNSS智能节电 装置100以及GNSS芯片处理模块103，其中：
卫星信号接收天线系统101，设置为接收周围环境中的卫星信号；
ELNA模块102，与所述卫星信号接收天线系统101相连接，设置为接收来自于所述卫星信号接收天线系统101中的卫星信号，对卫星信号进行放大处理后发送给所述GNSS智能节电装置100；
GNSS智能节电装置100，连接于所述ELNA模块102和所述GNSS芯片处理模块103之间，设置为监测来自于所述ELNA模块102的卫星信号，在未监测到卫星信号时通知所述GNSS芯片处理模块103进入休眠状态；
GNSS芯片处理模块103，设置为处理卫星信号。
本实施例方案中，通过GNSS智能节电装置100使GNSS芯片处理模块103在没有卫星信号时进入休眠状态，从而解决了GNSS芯片处理模块103在没有卫星信号时保持搜索状态而造成手机功耗大发热高的问题。
在实际应用中，GNSS定位系统会面临有卫星信号和没有卫星信号两种情况，本实施例方案主要用于处理没有卫星信号时的情况，对于周围环境有卫星信号的情况，GNSS定位系统可以按照正常的流程进行相应处理。
因此，本发明实施例中，GNSS智能节电装置100还设置为在监测到卫星信号时，通知所述GNSS芯片处理模块103启动工作。需要说明的是，在其他实施例中，在所述GNSS智能节电装置100监测到卫星信号时，也可以根据实际情况由其他装置来通知所述GNSS芯片处理模块103启动工作，本实施例对此不作具体限定。
此外，由于在实际使用过程中GNSS定位功能不是一直处于开启状态，因此，可选地，在卫星定位功能开启时，可以利用所述GNSS芯片处理模块103来通知所述GNSS智能节电装置100卫星定位功能已开启。
因此，在进一步实施方案中，GNSS芯片处理模块103还设置为在卫星定位功能启动时将卫星定位启动馈线信号发送给所述GNSS智能节电装置100，以便GNSS智能节电装置100在卫星定位功能开启后开始工作，监测来自于所述ELNA模块102的卫星信号。
根据一示例性实施例，所述GNSS芯片处理模块103在接收到启动卫星定位请求后，向所述GNSS智能节电装置100发送通知信息；所述GNSS智能节电装置100接收到来自于所述GNSS芯片处理模块的通知信息时，监测来自所述ELNA模块的 卫星信号。
本实施例方案，通过GNSS智能节电装置100使GNSS芯片处理模块103在没有卫星信号时进入休眠状态，从而解决了GNSS芯片处理模块103在没有卫星信号时保持搜索状态而造成手机功耗大发热高的问题。
进一步地，基于本发明GNSS定位系统第一实施例提出本发明GNSS定位系统第二实施例，该实施例与本发明GNSS定位系统第一实施例的区别在于：

以及，GNSS智能节电装置100还设置为，在预设时间内所述GNSS智能节电装置100监测到来自所述ELNA模块102的卫星信号时，通知所述GNSS芯片处理模块103启动工作，停止计时。
以计时1分钟为例，对本实施例方案进行说明，本实施例方案工作流程如图2所示：
首先，卫星定位功能启动，所述GNSS芯片处理模块103将此信息反馈给所述GNSS智能节电装置100；
所述GNSS智能节电装置100接收到来自所述GNSS芯片处理模块103的卫星定位功能开启馈线信号后，开始监测来自所述ELNA模块102的卫星信号；
在所述GNSS智能节电装置100监测到来自所述ELNA模块102的卫星信号时，通知所述GNSS芯片处理模块103启动工作并将卫星信号发送给所述GNSS芯片处理模块103；
所述GNSS智能节电装置100在未监测到来自所述ELNA模块102的卫星信号时，所述GNSS智能节电装置100开始计时，计时时长1分钟；
在接下来的1分钟内，若所述GNSS智能节电装置100监测到来自于所述ELNA模块102的卫星信号，则所述GNSS智能节电装置100将卫星信号发送给所述GNSS芯片处理模块103，并通知所述GNSS芯片处理模块103启动工作，同时结束计时。
在1分钟计时结束时，所述GNSS智能节电装置100未监测到来自于所述ELNA模块102的卫星信号，则所述GNSS智能节电装置100通知所述GNSS芯片处理模块103进入休眠状态。
通过上述实施例方案，GNSS智能节电装置100在监测到卫星信号时通知所述GNSS芯片处理模块103启动工作，没有监测到卫星信号时进行计时，在计时时间段内，所述GNSS智能节电装置100监测卫星信号，如果所述GNSS智能节电装置100监测到卫星信号，则通知所述GNSS芯片处理模块103启动工作并停止计时，若计时结束时所述GNSS智能节电装置100仍未未检测到卫星信号，则所述GNSS智能节电装置100通知所述GNSS芯片处理模块103进入休眠状态，从而解决了GNSS芯片处理模块103在没有卫星信号时保持扫描卫星信号造成移动终端功耗大发热高的问题。
进一步地，基于本发明GNSS定位系统第一或第二实施例，提出本发明GNSS定位系统第三实施例，与本发明GNSS定位系统第一或第二实施例的区别在于：
本实施例中，所述GNSS智能节电装置100，还设置为在所述GNSS芯片处理模块103进入休眠状态后监测来自于所述ELNA模块102的卫星信号，在监测到卫星信号时唤醒所述GNSS芯片处理模块103。
在实际使用过程中，用户可能从没有卫星信号的环境(如隧道等)移动到有卫星信号的环境，在这种情况下，唤醒所述休眠状态的GNSS芯片处理模块103使其启动工作是比较有必要的，本实施例方案中，GNSS智能节电装置100在所述GNSS芯片处理模块103进入休眠状态后监测到来自于所述ELNA模块102的卫星信号时，唤醒所述GNSS芯片处理模块103，很好的解决了这一问题。
需要说明的是，唤醒所述GNSS芯片处理模块103的主体也可以是GNSS定位系统内的其他装置，并不局限于本实施例方案中的GNSS智能节电装置100。
如图3，本实施例方案的一个完整工作流程所下：
首先，卫星定位功能启动，所述GNSS芯片处理模块103将此卫星定位启动馈线信号发送给所述GNSS智能节电装置100；
所述GNSS智能节电装置100接收到来自所述GNSS芯片处理模块103的卫星定位功能开启馈线信号，开始监测来自所述ELNA模块102的卫星信号；
若所述GNSS智能节电装置100监测到来自所述ELNA模块102的卫星信号，则通知所述GNSS芯片处理模块103启动工作并将卫星信号发送给所述GNSS芯片处理模块103；

在所述GNSS芯片处理模块103进入休眠状态后，若所述GNSS智能节电装置100监测到来自于所述ELNA模块102的卫星信号，则所述GNSS智能节电装置100唤醒所述GNSS芯片处理模块103。
通过上述实施例方案，GNSS智能节电装置100在监测到卫星信号时通知所述GNSS芯片处理模块103启动工作，没有监测到卫星信号时进行计时，在计时时间段内，所述GNSS智能节电装置100监测卫星信号，如果所述GNSS智能节电装置100监测到卫星信号，则通知所述GNSS芯片处理模块103启动工作并停止计时，若计时结束时所述GNSS智能节电装置100未检测到卫星信号，则所述GNSS智能节电装置100通知所述GNSS芯片处理模块103进入休眠状态，从而解决了GNSS芯片处理模块103在没有卫星信号时保持扫描卫星信号造成移动终端功耗大发热高的问题。此外，在所述GNSS芯片处理模块103进入休眠状态后，若所述GNSS智能节电装置100监测到来自于所述ELNA模块102的卫星信号，则所述GNSS智能节电装置100唤醒所述GNSS芯片处理模块103，及时保证移动终端正常的通信功能，提高用户体验。

在实际使用过程中，GNSS定位功能不是一直处于开启状态，本实施例方案中GNSS芯片处理模块103在卫星定位功能启动时，将卫星定位启动馈线信号发送给所述卫星信号监测模块402，以便GNSS智能节电装置100在卫星定位功能开启后开始工作，监测来自于所述ELNA模块102的卫星信号。
根据一示例性实施例，所述GNSS芯片处理模块103在接收到启动卫星定位请求后，向所述GNSS智能节电装置100的卫星信号监测模块402发送通知信息；所述GNSS智能节电装置100的卫星信号监测模块402接收到来自于所述GNSS芯片处理模块的通知信息时，监测卫星信号接收模块401是否接收到来自所述ELNA模块的卫星信号。
此外，在实际应用中，GNSS定位功能会面临有卫星信号和没有卫星信号两种情况，上述方案只说明了没有卫星信号时的处理情况，对于周围有卫星信号的情况，GNSS定位系统可以按照正常的流程进行相应处理。根据一示例性实施例，所述卫星信号监测模块402还设置为在监测到所述卫星信号接收模块401接收到来自于所述ELNA模块102的卫星信号时通知所述GNSS芯片处理模块103启动工作。
在实际使用过程中，也可以采用其他装置在所述卫星信号监测模块402监测到所述卫星信号接收模块401接收到来自于所述ELNA模块102的卫星信号时，通知所述GNSS芯片处理模块103启动工作，并不局限于本方案中的卫星信号监测模块402。
