例如当信道质量由好变坏时，可以控制移动终端当前运行的视频通话应用切换为语音通话应用，这样操作者则无需自主判断视频通话质量以及手动控制视频通话应用，实现对应用的自动控制。
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明实施例提供的应用控制方法的流程图；
图2是本发明实施例提供的应用控制装置的一种结构示意图；
图3是本发明实施例提供的应用控制装置的另一种结构示意图。
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清楚、完整地描述，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做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。
请参阅图1，其示出了本发明实施例提供的应用控制方法的流程图，用于实现基于信道质量对应用的自动控制，可以包括以下步骤：
101：监测移动终端当前所用通信信道的信道质量。其中通信信道是移动终端与其他设备进行信息交互的通道，这一通信信道会受到其所在环境内噪声以及环境变化导致信道质量发生变化，而信道质量会影响到移动终端内运行的各个应用的运行情况，因此本发明实施例为能够基于信道质量来自动控制应用，则需要首先对通信信道的信道质量进行监测。
在本发明实施中，监测移动终端当前所用通信信道的信道质量的一种方式是：获取移动终端当前所用通信信道的多个质量参数，其中多个质量参数
至少包括：RSRP(Reference Signal Received Power，参考信号接收功率)、RSRQ(Reference Signal Received Quality，参考信号接收质量)、SNR(Signal Noise Ratio，信噪比)和CQI(Channel Quality Indicator，信道质量指示)，这些质量参数可以通过移动终端的物理层来监测，并将监测得到的各个质量参数的取值上传给应用层；在应用层中来进一步基于各个质量参数来确定信道质量。
其确定信道质量的过程可以是：将当前得到的多个质量参数分别与上一次获取到的多个质量参数进行一对一的对应比对，即将相邻两次获取到的多个质量参数中相同的质量参数进行比对，如将当前得到的SNR与上一次获取到的SNR进行比对。当多个质量参数中的至少一个质量参数相对于上一次获取到的质量参数发生变化时，基于变化后的质量参数得到当前所用通信信道的信道质量。
以RSRP为例，如RSRP<-130dB(分贝)指示信道质量很差；-100dB>RSRP>-130dB指示信道质量较差；-90dB>RSRP>-100dB指示信道质量较好；RSRP>-90dB指示信道质量好；因此当前得到的RSRP相对于上一次获取到的RSRP从-130dB提高为-110dB时，则指示当前的信道质量从很差提升为较差。
102：当监测到信道质量发生变化时，控制移动终端自动切换当前运行的第一应用的运行状态，其中当前运行的第一应用的运行状态基于信道质量而定，也就是说第一应用的运行状态是根据信道质量而变化，以使第一应用在信道质量发生变化的情况下正常运行。以在线观看视频为例，当信道质量较差时，移动终端需要将视频格式降低以适应当前信道质量。
以视频通话应用为例，当监测到信道质量由第一质量降低为第二质量时，控制移动终端当前运行的视频通话应用切换为语音通话应用；具体的：当监测到信道质量由第一质量降低为第二质量时，控制移动终端关闭视频图像传输功能，并发送第一指令至通信对端，第一指令指示通信对端关闭视频图像传输功能。其中第一质量对应的信道质量好于第二质量对应的信道指令，比如第一质量对应的是RSRP>-90dB，第二质量对应的是-90dB>
RSRP>-100dB。
如果后续监测到信道质量由第二质量提升为第一质量时，则可以控制移动终端当前运行的语音通话应用切换为视频通话应用，具体切换方式是：当监测到信道质量由第二质量提升为第一质量时，控制移动终端开启视频图像传输功能，并发送第二指令至通信对端，第二指令指示通信对端开启视频图像传输功能。
在这里需要说明的一点是：本发明实施例仅是以第一质量和第二质量为例进行说明，在实际应用过程中，其可以将信道质量划分成更多等级，并为不同等级下的信道质量分配视频通话应用的控制方式。例如信道质量具有四个等级，第一等级的信道质量下启用视频通话应用，且视频格式为高清；第二等级的信道质量下启用视频通话应用，且视频格式为标清；第三等级的信道质量下启用视频通话应用，且视频格式为流畅；第四等级的信道质量下将视频通话应用切换为语音通话应用，即关闭视频功能。
从上述技术方案可知，本发明实施例提供的应用控制方法可以监测移动终端当前所用通信信道的信道质量，当监测到信道质量发生变化时，控制移动终端自动切换当前运行的第一应用的运行状态，且当前运行的第一应用的运行状态基于信道质量而定。也就是说当信道质量发生变化时。第一应用的运行状态也会适当发生变化，例如当信道质量由好变坏时，可以控制移动终端当前运行的视频通话应用切换为语音通话应用，这样操作者则无需自主判断视频通话质量以及手动控制视频通话应用，实现对应用的自动控制。
此外在本发明实施例提供的应用控制方法中，上述当监测到信道质量由第一质量降低为第二质量时，控制移动终端当前运行的视频通话应用切换为语音通话应用是在监测到移动终端开启自动控制视频通话应用功能的情况下。也就是说移动终端在开启自动控制视频通话应用功能的情况下，移动终端则会基于信道质量的变化来自动控制视频通话应用。如当监测到所述信道质量由第一质量降低为第二质量时，控制移动终端当前运行的视频通话应用切换为语音通话应用；当监测到所述信道质量由第二质量提升为第一质量时，
控制移动终端当前运行的语音通话应用切换为视频通话应用。
如果监测到移动终端未开启自动控制视频通话应用功能，则在移动终端的界面中显示指示信道质量的内容，这样操作者则可以根据移动终端的界面中显示的内容这一客观信息来判断当前视频通话质量，并基于这一客观信息来决定是否对视频通话应用进行控制。
在本发明实施例中，移动终端在显示指示信道质量的内容时，可以以文字方式显示，例如“当前信道质量较好”，当然除此方式之外其还可以采用信号强度图标的方式来显示，对于其具体显示方式本发明实施例不加以限制。
与上述方法实施例相对应，本发明实施例还提供一种应用控制装置，其结构示意图如图2所示，可以包括：监测单元11和控制单元12。
监测单元11，用于监测移动终端当前所用通信信道的信道质量。其中通信信道是移动终端与其他设备进行信息交互的通道，这一通信信道会受到其所在环境内噪声以及环境变化导致信道质量发生变化，而信道质量会影响到移动终端内运行的各个应用的运行情况，因此本发明实施例为能够基于信道质量来自动控制应用，则需要首先对通信信道的信道质量进行监测。
在本发明实施中，监测单元11监测移动终端当前所用通信信道的信道质量的一种方式是：获取移动终端当前所用通信信道的多个质量参数，其中多个质量参数至少包括：RSRP、RSRQ、SNR和CQI，这些质量参数可以通过移动终端的物理层来监测，并将监测得到的各个质量参数的取值上传给应用层；在应用层中来进一步基于各个质量参数来确定信道质量。
其确定信道质量的过程可以是：将当前得到的多个质量参数分别与上一次获取到的多个质量参数进行一对一的对应比对，即将相邻两次获取到的多个质量参数中相同的质量参数进行比对，如将当前得到的SNR与上一次获取到的SNR进行比对。当多个质量参数中的至少一个质量参数相对于上一次获取到的质量参数发生变化时，基于变化后的质量参数得到当前所用通信信道的信道质量。
以RSRP为例，如RSRP<-130dB(分贝)指示信道质量很差；-100dB>RSRP>-130dB指示信道质量较差；-90dB>RSRP>-100dB指示信道质量较好；RSRP>-90dB指示信道质量好；因此当前得到的RSRP相对于上一次获取到的RSRP从-130dB提高为-110dB时，则指示当前的信道质量从很差提升为较差。
控制单元12，用于当监测到信道质量发生变化时，控制移动终端自动切换当前运行的第一应用的运行状态，其中当前运行的第一应用的运行状态基于信道质量而定，也就是说第一应用的运行状态是根据信道质量而变化，以使第一应用在信道质量发生变化的情况下正常运行。以在线观看视频为例，当信道质量较差时，移动终端需要将视频格式降低以适应当前信道质量。
以视频通话应用为例，控制单元12当监测到信道质量由第一质量降低为第二质量时，控制移动终端当前运行的视频通话应用切换为语音通话应用；具体的：当监测到信道质量由第一质量降低为第二质量时，控制移动终端关闭视频图像传输功能，并发送第一指令至通信对端，第一指令指示通信对端关闭视频图像传输功能。其中第一质量对应的信道质量好于第二质量对应的信道指令，比如第一质量对应的是RSRP>-90dB，第二质量对应的是-90dB>RSRP>-100dB。
如果后续控制单元12监测到信道质量由第二质量提升为第一质量时，则可以控制移动终端当前运行的语音通话应用切换为视频通话应用，具体切换方式是：当监测到信道质量由第二质量提升为第一质量时，控制移动终端开启视频图像传输功能，并发送第二指令至通信对端，第二指令指示通信对端开启视频图像传输功能。
在这里需要说明的一点是：本发明实施例仅是以第一质量和第二质量为例进行说明，在实际应用过程中，其可以将信道质量划分成更多等级，并为不同等级下的信道质量分配视频通话应用的控制方式。例如信道质量具有四个等级，第一等级的信道质量下启用视频通话应用，且视频格式为高清；第二等级的信道质量下启用视频通话应用，且视频格式为标清；第三等级的信
道质量下启用视频通话应用，且视频格式为流畅；第四等级的信道质量下将视频通话应用切换为语音通话应用，即关闭视频功能。
从上述技术方案可知，本发明实施例提供的应用控制装置可以监测移动终端当前所用通信信道的信道质量，当监测到信道质量发生变化时，控制移动终端自动切换当前运行的第一应用的运行状态，且当前运行的第一应用的运行状态基于信道质量而定。也就是说当信道质量发生变化时。第一应用的运行状态也会适当发生变化，例如当信道质量由好变坏时，可以控制移动终端当前运行的视频通话应用切换为语音通话应用，这样操作者则无需自主判断视频通话质量以及手动控制视频通话应用，实现对应用的自动控制。
此外在本发明实施例提供的应用控制装置中，上述当监测到信道质量由第一质量降低为第二质量时，控制移动终端当前运行的视频通话应用切换为语音通话应用是在监测到移动终端开启自动控制视频通话应用功能的情况下。也就是说移动终端在开启自动控制视频通话应用功能的情况下，移动终端则会基于信道质量的变化来自动控制视频通话应用。如当监测到所述信道质量由第一质量降低为第二质量时，控制移动终端当前运行的视频通话应用切换为语音通话应用；当监测到所述信道质量由第二质量提升为第一质量时，控制移动终端当前运行的语音通话应用切换为视频通话应用。其对应的结构示意图如图3所示，在图2基础上还可以包括：功能监测单元13和显示单元14。
功能监测单元13，用于监测移动终端是否开启自动控制视频通话应用功能，如果监测到移动终端开启自动控制视频通话应用功能，则触发控制单元12在信道质量由第一质量降低为第二质量时，控制移动终端当前运行的视频通话应用切换为语音通话应用。如果监测到移动终端未开启自动控制视频通话应用功能，则触发显示单元14在移动终端的界面中显示指示信道质量的内容，这样操作者则可以根据移动终端的界面中显示的内容这一客观信息来判断当前视频通话质量，并基于这一客观信息来决定是否对视频通话应用进行控制。
在本发明实施例中，移动终端在显示指示信道质量的内容时，可以以文字方式显示，例如“当前信道质量较好”，当然除此方式之外其还可以采用信号强度图标的方式来显示，对于其具体显示方式本发明实施例不加以限制。
在这需要说明一点：本发明实施例提及的视频通话应用可以是普通的视频通话应用，也可以是VoLTE(Voice over LTE)视频通话应用，其中VoLTE是基于IMS(IP Multimedia Subsystem，IP多媒体子系统)的语音业务。
