在未来的移动网络应用中，对业务量需求、终端数目以及终端种类都将会呈现爆发时的增长趋势。作为5G的重要场景和技术手段之一，机器间通信(Machine Type Communication，MTC)正受到越来越多的关注。在 MTC课题里，针对低成本低吞吐量类型终端的特性，提出了窄带物联网(Narrowband-Internet of Things，NB-IoT)的研究子课题：也就是利用200kHZ频带为NB-IoT低成本终端提供低吞吐量的无线通讯服务。
本申请发明人在实现本发明所实施技术方案的过程中，至少发现相关技术中存在如下技术问题：
当有下行数据到达时，核心网将触发携带下行数据到达指示信息的寻呼消息，终端需要在每个寻呼时机去监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)，根据PDCCH上是否携带跟该终端匹配的寻呼-无线网络临时标识(Paging-Radio Network Temporary Identifier，P-RNTI)，即可判断在该寻呼时机是否有发寻呼消息给本终端。对于NB-IoT或增强的机器间通信(enhanced-Machine Type Communication，eMTC)终端，在监听寻呼消息的时候，无论是否有寻呼消息都需要醒来并在寻呼时机监听寻呼消息，这对于低功耗的终端来说将会带来较大的耗电。

附图说明
附图用来提供对本发明技术方案的进一步理解，并且构成说明书的一部分，与本发明的实施例一起用于解释本发明的技术方案，并不构成对本发明技术方案的限制。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白，下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
在LTE系统中，如果要向处于空闲状态(比如无线资源控制(Radio Resource Control，RRC)状态为RRC-IDLE)的终端，如用户设备(User Equipment，UE)发送数据的时候，MME需要向UE注册的跟踪区(Tracking Area，TA)内的所有演进的节点B(eNodeB)发送寻呼(paging)消息，在eNodeB接收到核心网下发的寻呼消息后，先判断系统消息是否有变更，若有变更发生将在此寻呼消息中一同携带。然后eNodeB发送paging消息通知UE，如图1所示。UE根据寻呼时机(Paging Occasion，PO)的计算公式在相应的位置监听paging消息，当UE收到paging消息后将发起RRC连接请求，以便接收下行数据。MME在发送一次寻呼消息后根据UE在接下来是否执行相应的动作来判断本次寻呼是否被UE成功接收，如果没有被UE成功接收，将会在接下来的寻呼周期内继续寻呼该UE。

本方式中，所述通过专用的信令传递本基站支持的寻呼能力可以包括：
所述基站通过专用的信令传递本基站支持的寻呼能力至终端，并在S1口将本基站支持的寻呼能力传递至MME。
所述MME在后续的寻呼过程中可以在寻呼消息里将所述的寻呼能力携带给基站。
相应地，所述寻呼方法还可以包括：
所述基站从所述MME发送的寻呼消息里获取本基站支持的寻呼能力。
一种方式中，所述基站可以支持一种或多种无线接入制式，其中无线接入制式包括支持覆盖增强和不支持覆盖增强。
一种方式中，所述寻呼方法还可以包括：
所述基站通过以下一种或多种方式向终端指示驻留模式：
通过系统消息广播驻留模式；
通过专用的信令指示驻留模式；
所述驻留模式可以表示为：驻留模式信息和/或驻留模式倾向信息。
其它方式中，如果驻留模式是默认的、预定的或根据预定规则可以确定的，也可以不指示驻留模式。
本方式中，所述通过专用的信令传递驻留模式可以包括：
所述基站通过专用的信令传递驻留模式至终端，并在S1口将所述的驻留模式传递至MME。
MME在后续的寻呼过程中可以在寻呼消息里将所述的驻留模式携带给基站。
相应地，所述寻呼方法还可以包括：
所述基站从所述MME发送的寻呼消息里获取驻留模式。
本方式中，所述基站采用所选择的寻呼方式发送寻呼消息可以包括：
所述基站根据向终端指示的驻留模式，确定空闲态的终端所驻留或优先驻留的系统，在相应的驻留或优先驻留的系统上发送寻呼消息；
当在终端优先驻留的系统上发送寻呼消息时，在一次寻呼失败后，所述基站在终端和所述基站均支持的至少其中一种系统上继续寻呼。
本方式中，所述确定空闲态的终端所驻留或优先驻留的系统可以包括：

所述基站接收核心网下发的寻呼消息后，解调出终端的寻呼能力，对 于NB-IoT终端，如果终端支持带唤醒信号的寻呼，且本基站也支持NB-IoT系统带唤醒信号的寻呼，则选择利用带唤醒信号寻呼方式进行寻呼；对于eMTC终端，如果终端支持在M个PRB上监听寻呼消息、本基站支持eMTC系统的在N个PRB上发送寻呼消息，M和N是小于7的正整数，且M≥N，则选择利用N个PRB发送寻呼消息。
其中，当M＝1，N＝1时，本方式相当于：对于eMTC终端，如果终端支持在一个PRB上监听寻呼消息，且本基站也支持eMTC系统的在一个PRB上发送寻呼消息，则选择利用一个PRB发送寻呼消息。
本方式中，对于NB-IoT终端，如果终端和基站中至少一个不支持带唤醒信号的寻呼，则可以选择采用常规的寻呼方法；对于eMTC终端，如果以下条件至少一个成立，则可以采用常规的寻呼方法：终端不支持在M(M是小于7的正整数)个PRB上监听寻呼消息、基站不支持在N(N是小于7的正整数)个PRB上发送寻呼消息、M＜N。
本方式中，对于NB-IoT，设计带唤醒信号的寻呼，即当终端较长时间无数据发生时通过唤醒信号通知终端无需再去监听后续的寻呼时机以达到节电的目的。
本方式中，对于eMTC终端，每次监听寻呼的带宽达到1.4MHZ，如此大的带宽，对于像eMTC这样的低成本终端来说，无疑对功耗带来较大的影响；本实现方式在较窄的带宽上收发寻呼消息，将有利于降低eMTC终端的功耗。

本实施例的其它实现细节可参见实施例一、二。
下面用7个实施示例来说明本发明的上述实施例。
实施示例1：
为本发明提供的寻呼方法的实施示例：
在通信系统中，基站支持一种或多种无线接入制式，如2G、3G、4G等，在一种无线制式下支持一种或多种无线接口，如eMTC、NB-IoT。基站需对于eMTC、NB-IoT无线接口分别下发本基站支持的寻呼方式，基站支持的寻呼方式包括：对于NB-IoT无线接口是否支持带唤醒信号的寻呼、对于eMTC无线接口是否支持在N个PRB上发送寻呼消息。在本实施示例 中，N＝1。
所谓的带唤醒信号的寻呼，可以在原有PO的位置上选择部分PO用于发送该唤醒信号，也可以额外的确定一些新的PO位置用于发送该唤醒信号。唤醒信号用于指示终端在接下来的PO是否需要继续监听，如核心网判断在接下来一段时间内无下行业务发生，将发送唤醒信号寻呼以指示终端的行为，终端在接收到该指示信息后，在接下来的PO将不执行监听，直至下一个唤醒信号时机再执行监听该唤醒信号。
eMTC窄带系统的带宽为1.4MHZ，对于eMTC这种要求低功耗的终端如果在PO位置监听1.4MHZ的带宽，势必带来较大的功耗，如果寻呼消息仅在一个PRB的频带范围内发送的话，这样在每个PO只需要监听1.4MHZ带宽，可进一步降低因为监听寻呼消息而带来的功耗。
在其它实施示例中，基站可以在N个PRB上发送寻呼消息，终端的寻呼能力包括可以在M个PRB上监听寻呼消息，N和M均是小于7的正整数，且M≥N。
实施示例2：
为本发明提供的寻呼方法中，基站下发本基站支持的寻呼能力的实施示例：
基站下发寻呼能力至终端的方式包括以下至少一种：通过广播消息下发寻呼能力信息和/或寻呼方式倾向信息、通过专用的信令传递支持的寻呼能力信息和/或寻呼方式倾向信息。
通过广播消息下发寻呼能力信息和/或寻呼方式倾向信息的方式中，基站将寻呼能力信息和/或寻呼方式倾向信息以系统消息携带的方式在小区范围广播。
通过专用的信令传递支持的寻呼能力信息和/或寻呼方式倾向信息的方式中，如在RRC释放连接的过程，基站在RRC release消息里携带寻呼能 力信息和/或寻呼方式倾向信息。并且基站需要在S1口将所述的寻呼能力信息和/或寻呼方式倾向信息传递至MME，MME在后续的寻呼过程中需在寻呼消息里将所述的寻呼能力信息和/或寻呼方式倾向信息携带给基站，基站将基于该寻呼能力信息和/或寻呼方式倾向信息，以及终端的寻呼能力发送寻呼消息。
实施示例3：
为本发明提供的寻呼方法中，空闲态终端驻留模式确定的实施示例：
基站可能支持覆盖增强的接入制式，也可能不支持覆盖增强的接入制式。而终端也可能支持覆盖增强或不支持。因此基站和终端需要协商驻留系统。如果基站支持覆盖增强的无线接入制式，终端也支持覆盖增强的无线接入制式，那么终端优先驻留在覆盖增强的无线接入制式下。如，支持覆盖增强的LTE终端，基站也支持覆盖增强，那么终端优先驻留在eMTC窄带制式下；如果基站不支持覆盖增强，那么终端需驻留在LTE制式下。
实施示例4：
为本发明提供的寻呼方法中，基站向终端指示驻留模式的实施示例：
基站通过以下至少一种方式向终端指示驻留模式：通过系统消息广播驻留模式信息和/或驻留模式倾向指示信息、通过专用的信令指示驻留模式信息和/或驻留模式倾向指示信息。
通过广播消息下发驻留模式信息和/或驻留模式倾向指示信息的方式中，基站将驻留模式信息和/或驻留模式倾向指示信息以系统消息携带的方式在小区范围广播。
通过专用的信令传递驻留模式信息和/或驻留模式倾向指示信息的方式包括：基站通过专用的信令传递驻留模式信息和/或驻留模式倾向指示信息至UE，基站需要在S1口将所述的驻留模式信息和/或驻留模式倾向指示信息传递至MME，MME在后续的寻呼过程中需在寻呼消息里将所述的驻留 模式信息和/或驻留模式倾向指示信息携带给基站，基站将基于所述的驻留模式信息和/或驻留模式倾向指示信息发送寻呼消息。
实施示例5：
为本发明提供的寻呼监听方法中，终端上报寻呼能力的实施示例：
终端通过以下一种或多种方式上报寻呼能力：
通过NAS信令携带寻呼能力透传至基站，后续基站可以将该寻呼能力再通过S1口传递至MME；
通过AS信令携带寻呼能力传递给基站，后续基站可以将该寻呼能力再通过S1口传递至MME。
其中，通过非接入层信令透传寻呼能力时，如在跟踪区更新(Tracking Area Update，TAU)过程中，终端通过NAS消息将寻呼能力透传至基站，基站再通过S1口传给MME，在后续寻呼过程，MME会将所述的终端的寻呼能力通过寻呼消息带给基站，从而使基站获取终端的寻呼能力。
其中，通过接入层信令携带寻呼能力传递给基站时,如在RRC连接建立的过程，在RRC信令中携带终端的寻呼能力，基站再通过S1口传递至MME，在后续寻呼过程，MME会将所述的终端的寻呼能力通过寻呼消息带给基站，从而使基站获取终端的寻呼能力。
实施示例6：
为本发明提供的寻呼方法中，基站发送寻呼消息的实施示例：
基站在接收到MME下发的寻呼消息，首先解调出终端的寻呼能力，另外在寻呼消息里如果包含终端的驻留模式(比如驻留模式信息和/或驻留模式倾向信息)，基站将在协商的驻留模式下根据协商的寻呼能力发送寻呼消息。如终端是支持覆盖增强的LTE终端，并支持一个PRB的寻呼能力(即支持在一个PRB的频带范围内监听寻呼消息)，且基站也支持覆盖增强、一个PRB的寻呼能力(即支持在一个PRB的频带范围内发送寻呼消息)，那 么基站将在一个PRB上向eMTC终端发送寻呼消息。如终端是支持带唤醒信号寻呼能力的NB-IoT的终端，且基站也支持带唤醒信号寻呼的能力，那么基站将在唤醒信号PO发送唤醒信号。
