【附图说明】
图1是本发明移动通信终端的电源管理方法一实施例的流程图；
图2是本发明移动通信终端一实施例的结构示意图；
图3是图2所示的移动通信终端的工作流程图。
【具体实施方式】
图1是本发明移动通信终端的电源管理方法一实施例的流程图。如图1所示，该移动通信终端的电源管理方法包括以下步骤：
步骤S101：利用WIFI芯片通过WIFI天线与无线接入点建立WIFI连接。
其中，在WIFI芯片与无线接入点建立WIFI连接前，先要通过WIFI天线搜索周围的无线接入点，然后选定要连接的无线接入点，再通过WIFI天线发送请求信号请求连接，而无线接入点收到该请求信号后，向WIFI天线发送确认信号，WIFI芯片通过WIFI天线接收到确认信号后，成功建立WIFI连接。
步骤S102：利用至少一网络应用模块通过WIFI芯片以及WIFI天线与无线接入点进行数据交互。
其中，网络应用模块包括浏览器、即时聊天工具、视频播放客户端和网络游戏等，当网络应用模块工作时，WIFI芯片就会通过WIFI天线与无线接入点进行数据交互，以进行包括信息、图片、短信、视频等数据的交互。在本实施例中，数据交互包括数据上传以及数据下载，其中数据交互方向可以从移动通信终端到无线接入点，也可以从无线接入点到移动通信终端。
步骤S103：利用数据业务管理模块实时统计与无线接入点进行数据交互的网络应用模块的数量；
其中，网络应用模块与无线接入点进行数据交互的数量可以有多个，且多个网络应用模块可以同时进行数据交互，例如用户一边浏览网页一边下载音乐或视频，数据业务管理模块则实时统计该数量并记录。在本实施例中，数据业务管理模块在WIFI连接断开时设置与无线接入点进行数据交互的网络应用模块的数量为0。
步骤S104：利用电源管理模块向WIFI芯片供电，从数据业务管理模块获取数量并进行判断，在判断到数量为0时，停止向WIFI芯片供电，在判断到数量不为0时，保持向WIFI芯片供电。
其中，移动通信终端包括有显示器，显示器作为与用户交互的主要窗口，能够在很大程度上表明用户是否在使用移动通信终端，例如显示器关闭时，用户就很有可能没有使用移动通信终端。电源管理模块在检测到移动通信终端的显示器关闭时，从数据业务管理模块获取数量并进行判断，在判断到数量为0时，即没有网络应用模块与无线接入点进行数据交互时，停止向WIFI芯片供电，在判断到数量不为0时，即有至少一网络应用模块正在与无线接入点进行数据交互时，保持向WIFI芯片进行供电；电源管理模块在检测到移动通信终端的显示器未关闭时，保持向WIFI芯片进行供电。
另一方面，由于存在显示器没有关闭时，移动通信终端却处于待机状态的情况，例如移动通信终端处于待机状态，但是显示器却显示屏幕保护画面。因此，电源管理模块在检测到移动通信终端处于待机状态一预定时间时，从数据业务管理模块获取数量并进行判断，在判断到数量为0时，停止向WIFI芯片供电，在判断到数量不为0时，保持向WIFI芯片进行供电；在检测到移动通信终端未处于待机状态一预定时间时，保持向WIFI芯片供电。
图2是本发明移动通信终端一实施例的结构示意图。如图2所示，移动通信终端包括：基带信号处理芯片20和 WIFI模组21。WIFI模组21与基带信号处理芯片20之间通过SDIO接口总线连接，SDIO接口总线包括SDC_CLK、SDC_CMD以及SDC_DATA。基带信号处理芯片20通过SDIO接口总线与WIFI模组21进行通信，可以使用WIFI模组21进行数据操作，以及对WIFI模组21进行控制等。
在本实施例中，WIFI模组21包括WIFI芯片211和WIFI天线212， WIFI天线212负责搜索无线接入点的信号，并接收或者发送数据。WIFI芯片211与WIFI天线212电连接，WIFI芯片211通过WIFI天线212接收或者发送数据，从而与无线接入点进行通信。
WIFI模组21用于连接电源，以为WIFI芯片211的正常工作提供电能。若WIFI模组21与电源断开，WIFI芯片211则进入休眠模式，停止工作。
基带信号处理芯片20与WIFI芯片211连接，基带信号处理芯片20内部设置有：网络应用模块201、数据业务管理模块202和电源管理模块203。
网络应用模块201可以是浏览器、即时聊天工具、视频播放客户端等应用，用于通过WIFI模组21与无线接入点进行数据交互。当网络应用模块201需要使用或停止使用数据业务时，通知数据业务管理模块202进行记录管理。
数据业务管理模块202用于实时统计与无线接入点进行数据交互的网络应用模块201的数量，以掌握数据交互的情况，使得电源管理模块203在控制WIFI模组21休眠时，可以依据当前的数据交互的情况进行判断。
电源管理模块203用于向WIFI芯片211供电，进一步的，还用于整个系统的电源管理。电源管理模块203通过从数据业务管理模块202获取与无线接入点进行数据交互的网络应用模块201的数量并进行判断。在判断到数量为0时，停止向WIFI芯片211供电，WIFI芯片211进入休眠模式，处于最小功耗状态；在判断到数量不为0时，保持向WIFI芯片211供电，WIFI芯片211正常工作。
下面将介绍本实施例的移动通信终端的具体工作流程，请一并参阅图3，图3是图2所示的移动通信终端的工作流程图。如图3所示，移动通讯终端300可以为手机、个人数字助理或平板电脑等，移动通讯终端300的具体工作流程包括以下步骤：
步骤301：WIFI芯片211通过WIFI天线212请求与无线接入点建立WIFI连接。
其中，WIFI芯片211经过相关初始化，进行对无线输入点信号的扫描，将当前范围内的无线接入点以列表方式列出，用户选择某个无线接入点，请求与该无线接入点建立WIFI连接。
步骤302：判断WIFI连接是否建立，若是，则进行步骤303，若否，则进行步骤308。
其中，虽然WIFI天线212搜索到了某个无线接入点，但WIFI连接却不一定建立，比如该无线接入点需要输入密码、用户不期望建立WIFI 连接而不选择建立或者WIFI芯片211与无线接入点建立WIFI连接，但是信号很弱，导致WIFI连接断开等。
步骤303：至少一网络应用模块201与无线接入点进行数据交互。
步骤304：数据业务管理模块202实时统计与无线接入点进行数据交互的网络应用模块201的数量。
其中，WIFI芯片211进行相关初始化时，数据业务管理模块202也进行初始化，以使得WIFI连接建立时重新开始统计。数据业务管理模块202管理当前数据交互的情况，通过数组记录当前进行数据交互的网络应用模块201的ID，并通过一个变量记录数量，该数量与ID对应。当某个网络应用模块201进行数据交互时，数据业务管理模块202记录相应ID，并将变量加1。同样，当某个网络应用模块201停止进行数据交互时，数据业务管理模块202从数组中消除相应ID，并将变量减1。
步骤305：判断数量是否为0，若是，则进行步骤308，若否，则进行步骤306。
其中，由于与无线接入点进行数据交互的网络应用模块201的数量不为0，则保持向WIFI芯片211供电，保证了WIFI的正常使用。由于大多数情况下，移动通信终端的显示器在关闭时，用户是不会使用WIFI的，但是为了更好的使用户获得使用WIFI的良好体验，在显示器关闭时仍然进行判断。电源管理模块203在检测到显示器关闭时，从数据业务管理模块202获取数量并判断，在判断到数量为0时，进行步骤308；在判断到数量不为0时，进行步骤306。
考虑到移动通信终端处于待机状态已预定时间，而显示器并未关闭，比如此时显示器显示屏幕保护画面。电源管理模块203在检测到移动通信终端处于待机状态一预定时间时，从数据业务管理模块202获取数量并判断，在判断到数量为0时，进行步骤308；在判断到数量不为0时，进行步骤306。
在本实施例中，当判断到WIFI连接未建立，或WIFI连接中途断开时，设置与无线接入点进行数据交互的网络应用模块201的数量为0。
步骤306：电源管理模块203保持向WIFI芯片211供电。
其中，在电源管理模块203检测到显示器未关闭时，保持向WIFI芯片211供电以及在检测到移动通信终端未处于待机状态一预定时间时，保持向WIFI芯片211供电。
步骤307：WIFI芯片211正常工作，并同时进行步骤302。
其中，WIFI芯片211正常工作，会因为突然出现的WIFI连接断开情况而受到影响，例如无线接入点由于自身故障停止发出信号等，所以需要时刻判断WIFI连接是否建立。
步骤308：电源管理模块203停止向WIFI芯片211供电。
其中，在WIFI连接未建立或与无线接入点进行数据交互的网络应用模块201的数量为0的情况下，均停止向WIFI芯片211供电，能够节约移动通信终端的电能，尽可能最大程度地延长电池的使用时间。
步骤309：WIFI芯片211停止工作进入休眠模式。
其中，电源管理模块203是按照一定顺序停止供电的，即先关闭移动通信终端的显示器、触摸屏、按键灯等器件，最后再停止向WIFI芯片211供电。这样的顺序不会产生用户使用移动通信终端进行数据交互中断的情况，保证了WIFI的正常使用。
通过上述方式，本发明的移动通信终端及其电源管理方法通过电源管理模块从数据业务管理模块获取与无线接入点进行数据交互的网络应用模块的数量，并在判断到该数量为0时，停止向WIFI芯片供电，从而能够节约移动通信终端的电能，延长电池的使用时间，同时又保证WIFI的正常使用。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
