具体实施方式
本发明提供一种窄带物联网终端快速进入省电模式的方法、存储介质及移动终端，为使本发明的目的、技术方案及效果更加清楚、明确，以下对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
一种窄带物联网终端快速进入省电模式的方法，如图1所示，包括步骤：
S1、终端通过NB-IOT核心网络实时获取应用平台是否需要终端可达的信息；
S2、当应用平台不需要终端可达时，终端直接从连接模式进入省电模式。
因为连接模式下单位时间内耗电高但往往时间较短，空闲模式下的耗电其次且时间网络受网络控制，省电模式下的耗电最小而且时间最长，本发明通过设置应用平台不需要终端可达时，控制终端在接收到RRC连接释放消息时，直接从连接模式进入到省电模式状态，或者说是终端从连接模式进入到空闲模式后立即进入到省电模式状态，而不是在从连接模式进入到空闲模式后等待定时器超时再进入省电模式状态，省去了等待定时器超时的时间，从而节省了空闲模式下多余等待的时间及该段时间内产生的耗电。
3GPP Release 14定义的NB-IoT的网络架构是在原LTE网络上需要升级NB-IoT网络以及增加了网络能力开放层(SCEF)网元，SCEF网元是第三方应用和NB-IoT核心网通信的桥梁，本文在SCEF与应用平台和MME接口中增加是否需要可达信息的信令交互，并在空口消息RRC连接释放消息中增加是否需要终端可达的内容。
具体地，所述步骤S1中，NB-IOT核心网络向终端发送RRC连接释放消息时，所述RRC连接释放消息中包含有应用平台是否需要终端可达的信息，终端通过NB-IOT核心网络向终端发送RRC连接释放消息实时获取应用平台是否需要终端可达的信息，也即终端在获取RRC连接释放消息的同时即可获 取应用平台是否需要终端可达的信息，而无需再另外建立一条通信通道用以NB-IOT核心网络向终端发送应用平台是否需要终端可达的信息，节约了网络资源。
具体地，所述步骤S2中，当应用平台不需要终端可达时，终端从连接模式进入空闲模式后即进入省电模式，应用平台不需要终端可达即表明终端暂时不需要接收来自应用平台的数据或接受应用平台的控制，因而终端没必要保持待命状态(也即空闲模式)等待着定时器超时再进入省电模式状态，可以直接进入省电模式，也即进入了睡眠状态，在需要接收来自应用平台的数据时再唤醒，可以看出上述连接周期的耗电只包括两个部分，即连接过程中的耗电和PSM模式下的耗电，因为省电模式下终端的耗电较空闲模式下低，因而上述改变可以节约一定的电量，而考虑到物联网终端的巨大体量，总体来说，上述改变可以大大节省物联网终端电量消耗。
较佳地，所述窄带物联网终端快速进入省电模式的方法还包括步骤S3：
当应用平台需要终端可达时，终端从连接模式进入空闲模式，同时激活定时器，并在定时器超时后进入省电模式。应用平台需要终端可达时，应用平台需要向终端发送指令，因而需要终端保持待命状态(也即空闲状态)，以便于时刻接收应用平台的控制指令，当然，所述待命状态是有一定的时间限制的，该时间即是定时器的超时时间，具体地是在终端接收到包含在RRC连接释放消息中的应用平台需要终端可达的信息时，终端由连接模式进入空闲模式，同时定时器开启，若在定时器超时前未再接收到经NB-IOT核心网络向终端发送的应用平台数据或控制指令，则终端由空闲模式进入省电模式，也即有待命状态进入了睡眠状态；
可以看出上述步骤S3的连接周期中，窄带物联网终端的耗电包括三个部分，即连接过程中的耗电、空闲模式下的耗电和省电模式下的耗电。
较佳地，无论是通过步骤S2进入的省电模式，还是经步骤S3进入的省电模式，若周期性跟踪区更新或者上行数据传输，终端离开省电模式发起RRC连接建立，也即只要周期性跟踪区更新或者上行数据传输，窄带物联网终端均结束省电模式而发起建立RRC连接，进而进入连接模式，以便于向NB-IOT核心网络传输更新后的数据，保证数据及时准确。
现有技术中终端的耗电随时间变化的情况如图2所示，图2中，a点和d点为RRC连接释放消息的两个时间点，b点和e点为定时器超时的两个时间点，也即o点与a点之间以及c点与d点之间为连接模式状态，a点与b点之间以及d点与e点之间为空闲模式状态，b点与c点之间为省电模式；而经过上述步骤S2及S3，本发明中终端的耗电随时间变化的情况如图3所示，其中a点和d点为RRC连接释放消息的两个时间点(其中a点处的RRC连接释放消息中带有应用平台不需要终端可达的信息，d点处的RRC连接释放消息中带有应用平台不需要终端可达的信息)，e点为定时器超时的一个时间点，也即o点与a点之间以及c点与d点之间为连接模式状态，而a点与c点之间为省电模式状态，d点与e点之间为空闲模式状态，可以明显地看出本发明中终端省去了一部分空闲模式状态，而将其替换为省电模式，从而节省了终端耗电。
基于上述方法，本发明还提供了一种存储介质，其上存储有多条指令，其中，所述指令适合由处理器加载并执行如下步骤：
终端通过NB-IOT核心网络实时获取应用平台是否需要终端可达的信息；
当应用平台不需要终端可达时，终端直接从连接模式进入省电模式。
较佳地，所述的存储介质中，所述指令适合由处理器加载并继续执行：
当应用平台需要终端可达时，终端从连接模式进入空闲模式，同时激活定时器，并在定时器超时后进入省电模式。
较佳地，所述的存储介质中，所述指令适合由处理器加载并继续执行：
在省电模式时，若周期性跟踪区更新或者上行数据传输，终端离开省电模式发起RRC连接建立。
较佳地，所述的存储介质中，所述指令适合由处理器加载并具体执行：
NB-IOT核心网络向终端发送RRC连接释放消息时，所述RRC连接释放消息中包含有应用平台是否需要终端可达的信息，终端通过NB-IOT核心网络向终端发送RRC连接释放消息实时获取应用平台是否需要终端可达的信息。
基于上述方法，本发明还提供了一种移动终端，如图4所示，包括：
处理器100，适于实现各指令；以及
存储设备200，适于存储多条指令，所述指令适合由处理器加载并执行如上所述的窄带物联网终端快速进入省电模式的方法。
关于上述移动终端和存储介质的技术细节和好处已在上述方法中进行了详细阐述，此处不再赘述。
综上所述，本发明通过设置应用平台不需要终端可达时，控制终端在接收到RRC连接释放消息时，直接从连接模式进入到省电模式状态，或者说是终端从连接模式进入到空闲模式后立即进入到省电模式状态，而不是在从连接模式进入到空闲模式后等待定时器超时再进入省电模式状态，省去了等待定时器超时的时间，从而节省了空闲模式下多余等待的时间及该段时间内产生的耗电，解决了现有技术中窄带物联网终端在收到RRC连接释放消息之后总是需要进入空闲模式并在定时器超时后进入PSM省电模式造成耗电量较大的问题。
