相关申请的交叉引用
本申请要求在2020年01月31日提交中国专利局、申请号为202010077754.2、申请名称为“一种通信方法、终端、网络设备及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法、终端、网络设备及通信装置。
背景技术
随着社会的快速发展，移动终端例如手机越来越普及。手机不但具有通信功能、还具有强大的处理能力、存储能力、照相功能等。因此，手机不仅可以作为一种通信工具，更是用户的移动的文件库，它存储着用户的各种个人信息、照片、视频等，还可以绑定用户的社交账号、网银、移动支付账号等信息。因此，如果手机丢失，将会对用户的财产造成巨大的损害。
目前的手机找回方案为，用户丢失手机之后，在另一个设备上登录可用于找回手机的网址或者使用“查找我的手机”应用(application,简称APP)。在登录界面输入丢失的手机的系统账号、密码等。所述另一个设备向网络侧发送该手机的找回指令，网络侧寻呼手机。若手机处于联网状态，可以检测到网络侧的寻呼消息，然后向网络侧发送当前的位置。网络侧将手机当前的位置发送到所述另一台设备。
上述手机找回方案，均存在如下缺陷：
若捡到手机者捡到手机后，关机或者拔出手机中的用户识别模块(subscriber identification module，SIM)卡使手机无法联网时，该手机将检测不到网络侧发送的寻呼消息。那么，使用上述的手机找回方案将无法找回手机。
发明内容
本申请提供了一种通信方法、终端、网络设备及通信装置，用以提供一种用于找回丢失的终端的方案。
第一方面，提供一种通信方法，该方法应用于第一终端。当所述第一终端中的第一通信链路关闭时，通过所述第一终端中的第二通信链路监听第一信息；其中，所述第一通信链路和所述第二通信链路支持的频率不同；当监听到所述第一信息时，通过所述第二通信链路发送所述第一终端的当前位置。
示例性的，所述第一通信链路是所述第一终端中SIM卡的通信链路，所述第二通信链路是物联网通信链路。
以终端是手机为例，手机中设置两条通信链路，其中一条用于实现移动业务数据传输例如，拨打电话、上网等；另一条为物联网通信链路。当手机丢失后，捡到手机者可能会关机或者将手机中的SIM卡拔出。本申请提供的技术方案中，当手机被关机或SIM卡被 拔出时，手机中的用于实现移动业务数据传输的通信链路(即第一通信链路)关闭，手机可以通过物联网通信链路监听第一信息，当监听到第一信息则上报手机的地理位置。因此，在手机被关机或SIM卡被拔出而导致手机中的用于实现移动业务数据传输的通信链路关闭时，仍然可以找回手机，可以避免用户财产损失，用户体验较好。
应当理解的是，由于第一终端支持第一通信链路和第二通信链路。因此，第一终端有多种方式监听第一信息。
方式1：第一终端默认通过第二通信链路监听第一信息。
方式2，第一终端优先通过第一通信链路监听第一信息。当第一通信链路关闭时，再使用第二通信链路监听第一信息。
方式3，第一终端分别通过第一通信链路和第二通信链路监听第一信息。
上述方式2中，第一通信链路关闭，包括如下情况中的至少一种：
所述第一终端关机；

在一种可能的设计中，第一终端可以主动或被动的向网络设备发送能力信息，所述能力信息用于指示所述第一终端支持所述第二通信链路，和/或，所述第二通信链路支持的频率。
应当理解的是，第一终端自身支持所述第一通信链路和所述第二通信链路的情况下，可以向网络设备汇报该能力，以便网络设备通过第二通信链路(即物联网通信链路)向第一终端发送第一信息，以找回第一终端。因此，本申请实施例中，在手机被关机或SIM卡被拔出等导致手机中第一通信链路关闭的情况下，仍然可以找回手机，可以避免用户财产损失，用户体验较好。

再例如，所述第一通信链路关闭包括：第一终端中数据流量关闭而且未接入无线网络。这种情况下，所述第一终端检测到所述第一终端中数据流量开启，或接入无线网络时，向网络设备发送提示信息，以提示网络设备向第二终端指示第一终端数据流量开启，或接入无线网络。
第二方面，还提供一种通信方法，该方法应用于网络设备。网络设备接收到找回指令，所述找回指令用于找回第一终端；确定所述第一终端支持第一通信链路和第二通信链路，其中，所述第一通信链路和所述第二通信链路支持的频率不同；确定所述第一通信链路关闭时，通过所述第二通信链路向所述第一终端发送第一信息，所述第一信息用于指示所述第一终端上报地理位置。
示例性的，所述第一通信链路是所述第一终端中SIM卡的通信链路，所述第二通信链路是物联网通信链路。
以终端是手机为例，手机中设置两条通信链路，其中一条用于实现移动业务数据传输例如，拨打电话、上网等；另一条为物联网通信链路。当手机丢失后，捡到手机者可能会关机或者将手机中的SIM卡拔出导致第一通信链路被关闭。因此，本申请提供的技术方案中，网络设备寻呼手机时，可以通过物联网通信链路寻呼手机。也就是说，在手机被关机或SIM卡被拔出而导致手机中的用于实现移动业务数据传输的通信链路关闭时，仍然可以找回手机，可以避免用户财产损失，用户体验较好。
应当理解的是，由于第一终端支持第一通信链路和第二通信链路。因此，网络设备向第一终端发送第一信息有多种方式。
方式1：网络设备默认使用第二通信链路向第一终端发送第一信息。
方式2，网络设备优先通过第一通信链路向第一终端发送第一信息。当第一通信链路关闭时，再通过第二通信链路发送第一信息。

具体实施方式
下面将结合本申请以下实施例中的附图，对本申请实施例中的技术方案进行详尽描述。
以下，先对本申请实施例中涉及的部分用语进行解释说明，以便于本领域技术人员容易理解。
1)网络设备，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与无线终端通信的设备。例如，网络侧设备可以包括长期演进(long term evolution，LTE)系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括演进的分组核心网络(evolved packet core，EPC)、第五代移动通信技术(the 5th generation，5G)、新空口(new radio，NR)系统(也简称为NR系统)中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，Cloud RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。
网络侧设备还可以包括核心网设备，核心网设备例如包括访问和移动管理功能(access and mobility management function，AMF)等。
本申请实施例中，用于实现网络侧设备的功能的装置可以是网络侧设备，也可以是能够支持网络侧设备实现该功能的装置，例如芯片系统，该装置可以被安装在网络侧设备中。在本申请实施例提供的技术方案中，以用于实现网络侧设备的功能的装置是网络侧设备为例，描述本申请实施例提供的技术方案。
2)终端，诸如手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备(例如，手表、手环、智能头盔等)，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)，工业控制(industrial control)中的无线终端、无人驾驶(self driving)中 的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。本申请实施例提供的通信方法可以适用于上述任一种终端。
3)本申请实施例中的“用户身份”为逻辑概念。例如，“用户身份”可以对应SIM卡或签约用户信息或虚拟SIM卡或用户标识(如国际移动用户标识(international mobile subscriber identity，IMSI)或临时移动用户标识(temporary mobile subscriber identity，TMSI)等)。从网络侧的角度来看，不同的“用户身份”在逻辑上对应网络侧服务的不同通信实体，比如4G和5G系统中的UE，例如一个支持两个用户身份的终端，对于网络侧来说，可以看作两个通信实体。再例如，“用户身份”对应SIM卡或签约用户信息时，网络侧会将支持不同SIM卡或不同签约用户信息的两个终端识别为两个不同的通信实体，也会将支持多个不同SIM卡或多个签约用户信息的同一终端识别为多个不同的通信实体，即使在实际上，支持多个不同SIM卡或多个签约用户信息的终端只是一个物理实体。本申请实施例中将主要以“用户身份”对应SIM卡为例进行说明。
示例性地，SIM卡可以理解为终端接入移动网络的钥匙，为了便于描述，本申请实施例中将SIM卡以及其演进都统称为SIM卡。例如SIM卡可以是全球移动通信系统(global system for mobile communications，GSM)数字移动电话用户的身份识别卡，用于存储用户的身份识别码和密钥，并支持GSM系统对用户的鉴权；又例如，SIM卡也可以是全球用户识别卡(universal subscriber identity module，USIM)，也可以称为升级SIM卡。
4)蜂窝链路(cellular link)，终端和网络设备通过通用用户网络接口(user to network interface universal，Uu)通信的链路。具体而言，终端安装SIM卡后，该SIM卡与网络侧设备通过Uu口通信，实现通信(例如，打电话、上网等)功能。
5)物联网通信链路，是物体与物体之间通信的链路，区别于蜂窝链路，物联网通信基于物联网卡实现。物理网卡能够通过射频识别(radio frequency identification，RFID)、红外感应器、全球定位系统、激光扫描器等信息传感设备，按约定的协议，基于互联网连接不同物体实现信息交换。物联网通信主要渗透于视频监控，智慧交通、智能家居等领域。以智慧交通为例，不同车载设备之间或者车载设备与网络侧设备之间通过物联网通信。可以理解的是，物联网通信链路对应的时频资源和蜂窝链路对应的时频资源不同。
需要说明的是，本申请实施例中对蜂窝链路或物联网通信链路的名称不作限定，例如，蜂窝链路可以称为第一通信链路，物联网通信链路可以称为第二通信链路，或者，蜂窝链路可以称为主通信链路，物联网通信链路可以称为辅通信链路，等等。
6)本申请实施例涉及的至少一个，包括一个或者多个；其中，多个是指大于或者等于两个。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。例如，第一通信链路和第二通信链路仅用于区分不同通信链路，不是指示两条通信链路之间的顺序或相对重要性。
参见图1所示，为现有的手机找回方案的流程示意图。图1中以用户通过平板电脑找回丢失的手机为例。用户在平板电脑上登录可用于找回手机的网址，登录丢失的手机的系统账号和密码进行身份验证。当身份验证成功后，平板电脑向网络设备发送用于找回该手机的找回指令。网络设备发送寻呼消息。若丢失的手机处于联网状态，则能够检测网络侧 发送的寻呼消息，并向网络设备上报当前的位置。网络设备将所述当前位置发送给平板电脑。其中，手机卡处于联网状态包括手机开启数据流量或接入无线网络(wifi)等。
因此，现有的手机找回方案的前提为手机处于联网状态。一旦捡到手机者关机或拔出SIM卡或设置飞行模式使得手机无法联网，现有的手机找回方案将无法使用。
基于上述技术问题，本申请实施例提供一种通信方法。该方法可以用于找回手机。其中，手机中设置物联网通信模块，该物理网通信模块可以通过特定的通信链路(简称物联网通信链路)与网络侧通信，例如检测网络侧发送的寻呼消息。其中，特定的通信链路可以包括特定的传输资源例如频域资源。手机中的物联网通信链路与SIM卡的通信链路不同，或者说，二者是相互独立的通信链路。具体而言，物联网通信链路对应的频域资源和SIM卡的通信链路对应的频域资源不同。
在一些实施例中，当SIM卡的通信链路无法使用时，物联网通信链路不受影响，手机仍然可以通过物联网通信链路检测网络侧发送的寻呼消息。其中，SIM卡对应的通信链路无法使用的情况有多种，例如，SIM卡被拔出，或者设置飞行模式，或者数据流量被关闭等等。也就是说，丢失的手机中的SIM卡被拔出或设置飞行模式或关闭数据流量的情况下，通过申请实施例提供的通信方法，也可以找回手机。
在另一些实施例中，手机中的物联网通信链路不会因为手机的关机而关闭，所以，在手机关机状态下，仍然可以通过物联网通信链路检测网络侧发送的寻呼消息。也就是说，当手机关机时，通过本申请实施例提供的通信方法，也可以收回手机。
示例性的，参见图2，示出了本申请实施例提供的一种通信系统的示意图。该通信系统中包括第一终端、第二终端和网络侧设备。以用户通过第二终端找回丢失的第一终端为例，其中，第一终端例如为手机，第二终端例如为平板电脑。第一终端中设置物联网通信模块，该物联网通信模块可以与网络侧设备通信。而且，第一终端关机或SIM卡被拔出或设置飞行模式等不影响物联网通信模块与网络侧设备之间的通信。用户在第二终端上进行身份验证，验证通过之后，第二终端向网络侧设备发送用于指示找回第一终端的收回指令。网络侧设备接收到找回指令之后，通过物联网通信链路向第一终端发送第一信息，以指示第一终端上报地理位置。之后，网络侧设备将该地理位置发送给第二终端，用户通过第二终端查看该地理位置，找回第一终端。
以下实施例介绍本申请实施例提供的终端(例如图2所示的通信系统中的第一终端)的结构。
请参考图3，示出了本申请实施例提供的一种终端的结构组成示意图。如图3所示，终端100可以包括:SIM卡接口110、与SIM卡接口110耦合的管理器140、与管理器140耦合的处理器130，处理器130连接收发器150、与处理器130连接的物理网通信模块160。其中，上述处理器130可以为基带处理器(base band processor，BBP)。如图3所示，收发器150中包括射频Rx1通路和射频Tx1通路。其中，上述SIM卡接口110用于安装SIM卡，与SIM卡通信。管理器140可以向处理器130发送与SIM卡的业务相关的上行数据包。处理器130可以将SIM卡的各个上行数据包在射频Tx1通路上向网络侧设备发送上行数据包。处理器130还可以通过射频Rx1通路接收网络侧设备发送的下行数据包，然后将下行数据包发送管理器140，以通过管理器140将下行数据包发送给SIM卡。
应注意，本申请实施例中的射频Tx1通路也可以称为Tx1射频资源或发射器(transmitter)，射频Rx1通路也可以称为Rx1射频资源或接收器(receiver)。

物联网通信模块491包括处理器492和收发器493。物联网通信模块491用于实现手机找回功能。例如，处理器492用于通过射频Rx2通路接收网络侧设备发送下行数据包，例如寻呼消息；通过射频Tx2通路上向网络侧设备发送上行数据包，例如寻呼应答。
其中，处理器492可以集成在处理器410中，即属于处理器410中的一个功能模块。或者，是与处理器410不同的单独的器件。收发器493和收发器490可以是同一收发器，例如收发器490中包括Tx1通路、Tx2通路、Rx1通路和Rx2通路。其中，Tx1通路和Rx1通路用于实现与SIM卡相关的业务；Tx2通路和Rx2通路用于实现手机找回的业务。或者，Tx1通路和Tx2通路可以是不同通路，或者是同一通路的分时复用，Rx1通路和Rx2通路可以是不同通路或同一通路的分时复用。
在一些实施例中，物联网通信模块491可以始终处于工作状态，例如，物联网通信模块491实时的检测网络侧发送的用于找回手机的寻呼消息。
在另一些实施例中，物联网通信模块491可以无需一直处于工作状态。例如，在手机400中的SIM卡对应的通信链路正常的情况下，物联网通信模块491可以处于关闭状态(或者称为休眠状态、断电状态等)。当处理器410检测到关机操作、SIM拔出操作、设置飞行模式的操作或关闭数据流量的操作时，处理器410向物联网通信模块491发送唤醒指令，该唤醒指令用于唤醒物联网通信模块491，物联网通信模块491检测网络侧发送寻呼消息。
上述存储器460可包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、 至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据手机400的使用所创建的数据(例如音频数据、电话本等)。此外，存储器460可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。在以下实施例中，存储器460存储有使得手机400能运行的操作系统，例如苹果公司所开发的iOS@操作系统，谷哥大公司所开发的Android@开源操作系统，微软公司所开发的Windows@操作系统等。输入设备470(例如触摸屏)可用于接收输入的数字或字符信息，以及产生与手机400的用户设置以及功能控制有关的信号输入。具体地，输入设备470可以包括设置在手机400正面的触控面板，可收集用户在其上或附近的触摸操作(例如用户使用手指、触笔等任何适合的物体或附件在触控面板上或在触控面板附近的操作)，并根据预先设定的程式驱动相应的连接装置。可选的，触控面板可包括触摸检测装置和触摸控制器两个部分。其中，触摸检测装置检测用户的触摸方位，并检测触摸操作带来的信号，将信号传送给触摸控制器；触摸控制器从触摸检测装置上接收触摸信息，并将它转换成触点坐标，再送给处理器410，并能接收处理器410发送的指令并加以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型实现触控面板。显示器431(即显示屏)可用于显示由用户输入的信息或提供给用户的信息以及手机400的各种菜单的图形用户界面(graphical user inter face,GUI)。显示器431可包括设置在手机400正面的显示面板。其中，显示面板可以采用液晶显示器、发光二极管等形式。当触控面板检测到在其上或附近的触摸操作后，传送给处理器410以确定触摸事件，随后处理器410根据触摸事件的类型在显示面板上提供相应的视觉输出。虽然在图4中，触控面板与显示面板是作为两个独立的部件来实现手机400的输入和输出功能，但是在某些实施例中，可以将触控面板与显示面板集成而实现手机400的输入和输出功能，集成后的触控面板与显示面板可以简称为触摸显示屏。在另外的一些实施例中，上述触控面板还可以设置有压力感应传感器，这样用户在上述触控面板上进行触摸操作时，触控面板还能检测到该触摸操作的压力，进而手机400能够更准确地检测该触摸操作。手机400还可以包括至少一种传感器443，例如光传感器、运动传感器以及其他传感器。具体地，光传感器可包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节显示面板的亮度，接近光传感器设置在手机400的正面，当在手机400移动到耳边时，根据接近光传感器的检测，手机400关闭显示面板的电源，这样手机400可以进一步节省电量。作为运动传感器的一种，加速计传感器可检测各个方向上(一般为三轴)加速度的大小，静止时可检测出重力的大小及方向，可用于识别手机姿态(比如横竖屏转化、相关游戏、磁力计姿态校准)、振动识别相关功能(例如计步器、敲击)等；至于手机400还可包括陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。CODEC440、扬声器441，麦克风442可提供用户与手机400之间的音频接口。CODEC440可将接收到的音频数据转换后的电信号，传输到扬声器441，由扬声器441转换为声音信号输出；另一方面，麦克风442将收集的声音信号转换为电信号，由CODEC440接收后转换为音频数据，再将音频数据输出至RF电路410以发送给比如另一手机，或者将音频数据输出至存储器460以便进一步处理。处理器410是手机400的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器460内的软件程序，以及调用存储在存储器460内的数据，执行手机400的各种功能和处理数据，从而对手机进行整体监控。在一些实施例中，处理器410可包括一个或多个处理单元；处理器410 还可以集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器410中。上述手机400还可以包括蓝牙模块和Wi-Fi模块。蓝牙模块用于通过蓝牙这种短距离通讯协议来与其他设备进行信息交互。例如，手机400可以通过蓝牙模块与同样具备蓝牙模块的可穿戴电子设备(例如智能手表)建立蓝牙连接，从而进行数据交互。Wi-Fi属于短距离无线传输技术，手机400可以通过Wi-Fi模块帮助用户收发电子邮件、浏览网页和访问流媒体等，它为用户提供了无线的宽带互联网访问。手机400还包括给各个部件供电的电源491(例如电池)。电源可以通过电源管理系统与处理器410逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗等功能。可以理解的是，在以下实施例中，电源491可以用于给显示面板及触控面板供电。以下实施例中的方法均可以在具有上述硬件结构的手机400中实现。
参见图5所示，为本申请实施例提供的通信方法的流程示意图。该方法可以适用于图2所示的通信系统中。如图5所示，该方法的流程包括：
501，第一终端(例如手机)向核心网上报能力信息。在一些实施例中，能力信息可以用于指示第一终端是否支持第二通信链路，第二通信链路是不同于第一终端中的第一通信链路(例如，SIM卡对应的通信链路)之外的其他通信链路。其中，第二通信链路可以是物联网通信链路，第一通信链路可以是第一终端中SIM卡使用的通信链路，和/或，第一终端接入wifi时使用的通信链路。示例性的，能力信息中携带标志位，当该标志位为1时，指示第一终端支持物联网通信链路，当标志位为0时，指示第一终端不支持物联网通信链路。在另一些实施例中，能力信息用于指示第一终端支持第二通信链路。当核心网接收到第一终端发送的能力信息时，确定第一终端支持第二通信链路。当核心网未接收到第一终端发送的能力信息时，确定第一终端不支持第二通信链路。也就是说，第一终端不支持第二通信链路时，可以无需上报能力信息。
可以理解的是，如果第一终端接入核心网的过程中，已经向核心网上报第一通信链路以及第一通信链路支持的频率。这种情况下，上述能力信息用于指示第一终端支持第二通信链路，和/或，第二通信链路支持的频率。也就是说，第一终端仅上报第二通信链路和/或第二通信链路支持的频率即可。
作为另一种示例，能力信息用于指示第一终端支持第一通信链路和第二通信链路。也就是说，第一终端一并上报支持的第一通信链路和第二通信链路。可选的，能力信息用于指示第一终端支持第一通信链路时，还可以用于指示第一通信链路支持的频率，能力信息用于指示第一终端支持第二通信链路时，还可以用于指示第二通信链路的频率。
需要说明的是，第一终端可以主动或被动的上报能力信息。例如，第一终端可以在首次接入核心网时主动向核心网上报能力信息，或者，在接入核心网之后周期性的主动上报能力信息。或者，第一终端接收到核心网发送的用于查询第一终端是否支持第二通信链路的查询信息之后，向核心网发送第一终端的能力信息。可以理解的是，第一终端可以通过当前服务基站接收核心网发送的查询信息，并通过当前服务基站向核心网上报能力信息。
可以理解的是，第一终端还可以上报第一终端的标识，以便核心网区分每个终端对应的通信链路。示例性的，第一终端的标识可以携带于所述能力信息中。当然，第一终端还可以上报每条通信链路的链路标识、支持的频域资源(例如，频点、频段、频点组合或频段组合等)。示例性的，每条通信链路的链路标识、支持的频域资源等可以携带于所述能 力信息中，或者通过不同于所述能力信息的其它信息发送。
可选的，第一终端还可以上报第二通信链路支持的能力，例如，第二通信链路用于在核心网接收到其它设备发送的用于找回第一终端的找回指令时，使用第二通信链路下发第一终端的寻呼指令。
502，核心网存储该第一终端的能力信息。
可以理解的是，核心网中存储海量的终端的能力信息，核心网可以通过终端的标识定位该终端的能力信息，以便使用。
503，第二终端(例如平板电脑)检测到用于对所述第一终端的身份信息进行验证的操作之后，对所述身份信息进行验证，若验证通过，执行504。
应理解，第二终端可以是除去第一终端之外的其它终端，例如平板电脑、台式电脑、手机等。
示例性的，参见图6所示，为第二终端的显示界面的示意图。如图6中的(a)所示，第二终端的显示界面中显示“查找我的手机”的应用的图标601。第二终端检测用户点击该图标601的操作时，显示登录界面，该登录界面例如为图6中的(b)所示的界面。用户可以在登录界面输入第一终端的身份信息。示例性的，身份信息包括第一终端的系统账号和密码。第二终端检测到用户点击登录控件603的操作，响应于该操作，进行身份验证，若验证通过，执行步骤504。
504、第二终端向核心网发送找回指令，该找回指令中携带第一终端的标识。
可以理解的是，第二终端可以通过第二终端的当前服务基站向核心网发送找回指令。
505，核心网基于第一终端的标识查询第一终端的能力信息。
在502的描述，核心网中存储大量的终端的能力信息，所以，核心网可以根据第一终端的标识查询第一终端的能力信息。
506，核心网向第一终端的服务基站发送寻呼消息，该寻呼消息中包括第一终端的能力信息。
示例性的，核心网可以向所有基站广播寻呼消息，每个基站接收到寻呼消息之后，可以判断是否有第一终端接入，若是，将寻呼消息发送给第一终端。或者，核心网发送寻呼消息之前，判断第一终端接入哪个基站，例如，核心网向每个基站发送查询消息，该查询消息用于查询是否有第一终端接入。若某个基站确定第一终端接入，则向核心网反馈用于指示第一终端接入到该基站的确认指示，核心网向该基站发送寻呼消息。
第一终端的服务基站接收到核心网发送的寻呼消息之后，解析该寻呼消息得到第一终端的能力信息。第一终端基于该能力信息可以确定第一终端支持第一通信链路和第二通信链路，其中，第一通信链路用于传输移动业务数据，第二通信链路为物联网通信链路。
507，第一终端的服务基站判断第一通信链路是否关闭；若是，则执行508，若否，则执行509。
服务基站判断第一通信链路是否关闭的方式有多种。例如，服务基站中存储第一终端当前的状态，例如关机或开机状态等。基站可以根据存储的第一终端的状态确定第一终端的第一通信链路是否关闭。假设服务基站确定存储的第一终端的状态为关机状态，确定第一通信链路关闭。再例如，服务基站通过第一通信链路向第一终端发送探测消息，若预设时长内未收到第一终端的反馈信号，确定第一终端的第一通信链路关闭。以第一终端是手机为例，当手机中SIM卡无信号(例如处于飞行模式或SIM卡被拔出)时，手机中第一 通信链路关闭，手机接收不到服务基站通过第一通信链路下发的信号。
当服务基站确定第一通信链路关闭时，执行508，则通过第二通信链路向第一终端发送第一信息；否则，则执行509，即通过第一通信链路向第一终端发送第一信息。所述第一信息用于指示第一终端上报地理位置。具体而言，服务基站通过第一通信链路向第一终端发送第一信息可以是服务基站在第一通信链路支持的频域资源上发送第一信息。服务基站通过第二通信链路向第一终端发送第一信息可以是服务基站在第二通信链路支持的时频资源上发送第一信息。
508，基站通过第二通信链路发送第一信息，该第一信息用于指示第一终端上报地理位置。
509，基站通过第一通信链路发送第一信息，该第一信息用于指示第一终端上报地理位置。
在上面的实施例中，507-509中，第一终端的服务基站接收到核心网下发的寻呼消息之后，判断第一终端的第一通信链路是否关闭，根据判断结果决定使用第一通信链路还是第二通信链路下发第一信息。在另一些实施例中，服务基站无需判断第一通信链路是否关闭。例如，服务基站先通过第一通信链路下发第一信息，若预设时长内未收到第一终端上报的地理位置，再通过第二通信链路下发第一信息；或者，同时使用第一通信链路和第二通信链路下发第一信息，等等，本申请实施例不作限定。
可以理解的是，对于第一终端而言，当第一终端中第一通信链路通信恢复正常时，第二通信链路可以关闭，以节省功耗。因此，第一终端可以在第一通信链路支持的频域资源上检测第一信息。其中，第一通信链路通信恢复正常可以包括第一终端中开启数据流量或接入wifi。
或者，当第一通信链路关闭时，启动第二通信链路，在第二通信链路支持的频域资源上监听第一信息。其中，第一通信链路关闭可以包括多种情况。例如，关机、SIM卡被拔出、被设置飞行模式、关闭数据流量、或，关闭数据流量且未接入wifi，等等。
510，第一终端向第二终端发送当前的地理位置。具体而言，第一终端通过第一终端的当前服务基站上报当前地理位置，该基站向核心网上报地理位置，核心网通过第二终端的当前服务基站向第二终端发送所述第一终端的当前的地理位置。
可选的，第一终端当前的地理位置可以是第一终端当前接入的小区的位置；或者，是第一终端内的GPS检测到的位置。示例性的，当手机中的GPS功能被关闭时，第一终端当前的地理位置为第一终端当前接入的小区的位置，当手机中的GPS功能开启时，第一终端当前的地理位置为第一终端中GPS检测到的位置。
示例性的，参见图6中的(c)所示，平板电脑向核心网侧发送手机的找回指令之后，收到核心网发送的手机的地理位置，并显示该地理位置，例如以地图形式显示。
在另一些实施例中，第一终端向第二终端发送地理位置之后，第一终端中的网物联网通信模块还可以检测手机的开机操作，若检测到开机操作，物理网通信模块可以通过核心网向第二终端发送提示信息，该提示信息用于提示手机开机，是否删除第一终端中存储的内容(图片、视频等)。其中，物联网通信模块检测开机操作可以包括，第一终端中的处理器检测开机操作之后，向物联网通信模块发送开机指令，物联网通信模块基于该开机指令确定手机开机。
示例性的，参见图7所示，为第二终端的显示界面的示意图。第二终端显示提示信息 701，该提示信息701用于指示丢失的手机开机，是否删除手机存储内容。若第二终端检测到用户选择“是”控件702，则第二终端向第一终端发送确认删除指示(第二终端可以通过核心网向第一终端发送确认删除指示)，第一终端删除存储内容。
以上实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。还应当理解，在本申请实施例中，“一个或多个”是指一个、两个或两个以上；“和/或”，描述关联对象的关联关系，表示可以存在三种关系；例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
