具体实施方式
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，所描述的实施例仅仅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。
术语“载波信号”用于表示基站下发给终端的，用于呼叫该终端的信号。若终端无法接收到该载波信号，则当其他终端呼叫该终端时，该终端不能接收到该呼叫，不会播放被叫铃声。
术语“外放扬声器”表示用于外放声音的扬声器。
请参阅图1，本发明实施例中防止终端丢失的方法一个实施例包括：
101、当终端接收到特定指令时，所述终端检测当前是否处于锁屏状态，所述特定指令用于表示控制终端音量降低的指令和/或使终端无法接收到载波信号的指令；
在终端被盗后，偷盗者为了隐藏该终端，可能会在拿到终端后向终端发出控制终端音量降低或使终端无法接收到载波信号这类的特定指令，当终端接收到这类特定指令时，该终端并不会马上执行接收到的特定指令，会先检测当前是否处于锁屏状态。
该特定指令有很多，具体的，例如静音指令、调小音量指令均为控制终端音量降低的指令，关机指令或拔SIM卡指令为使终端无法接收到载波信号的指令，可以理解的是，还可以有其他的控制终端音量降低或使终端无法接收到载波信号的指令，此处不作限定。
需要说明的是，上述锁屏状态与黑屏状态不同，锁屏状态下可能是黑屏状态，也可能不是黑屏状态，黑屏状态下可能是锁屏状态，也可能不是锁屏状态。具体的，黑屏状态仅仅表示屏幕没有点亮，任意的操作都可能解除该黑屏状态，让屏幕点亮，而锁屏状态并不是任意的操作都能解除，必须要采用预置的解锁方式才能解除，具体的解锁方式有很多种，例如需要用户输入解锁密码，或需要验证用户的指纹，虹膜等等，还可以有很多其他的解锁方式，此处不作限定。
102、当检测到处于锁屏状态时，所述终端不执行所述特定指令，控制终端音量增大和/或利用外放扬声器播放警示音；
当检测到处于锁屏状态时，该终端不执行上述接收到特定指令，控制终端音量增大和/或利用外放扬声器播放警示音。
可以理解的是，在实际应用中，这里有三种可行的处理方式：
第一种：可以只控制终端音量增大，而不利用外放扬声器播放警示音；
第二种：可以不控制终端音量增大，但是会利用外放扬声器播放警示音；
第三种：可以既控制终端音量增大，又利用外放扬声器播放警示音。
根据实际应用的不同情况，可以选择其中的任一种，此处不作限定。
可以理解的是，该警示音可以采用常用的报警音，也可以由用户自定义特定的声音，例如特定歌曲，动物叫声等等，便于用户及时识别发出警示音的位置。
若用户及时发现终端丢失，而附近又有终端发出警示音，则用户可以及时的确定丢失终端的位置，找到该丢失的终端；
若用户及时发现终端丢失，而附近没有警示音发出时，表示偷盗者还没有对终端执行上述特定指令，或对终端发送上述特定指令后，终端没有执行接收到的特定指令且将终端音量增大了，此时用户可以利用其他终端直接呼叫该终端，通过寻找附近发出被叫铃声的终端确定该丢失的终端的位置。
103、当检测到不处于锁屏状态时，所述终端执行所述特定指令。
当检测到不处于锁屏状态时，则上述接收到的特定指令可能为用户正常的操作指令，该终端可以执行接收到的特定指令。
本发明实施例中，当终端接收到特定指令时，该终端先检测当前是否处于锁屏状态，该特定指令表示控制终端音量降低的指令和/或使终端无法接收到载波信号的指令，当确定处于锁屏状态时，该终端不执行该特定指令，控制终端音量增大和/或利用外放扬声器播放警示音，若用户及时发现终端丢失，而附近又有警示音发出，则用户可以根据警示音发出的位置确定丢失终端的位置，从而可以找到丢失的终端，若附近没有警示音发出，由于终端处于锁屏状态时不执行控制终端音量降低和/或使终端无法接收到载波信号的指令，用户也可以通过呼叫该终端，寻找附近发出被叫铃声的终端从而确定丢失终端的位置，也可以找到丢失的终端，从而在用户及时发现终端丢失时，增大了丢失的终端被用户找到的概率。
上面实施例中，可以利用外放扬声器播放警示音，在实际应用中，若终端被偷盗者盗取后，偷盗者可能会插入耳机导致终端中的外放扬声器无效，为了解决该问题，终端可以在锁屏状态下检测到耳机插入时作特殊处理，进一步的，在确定当前处于锁屏状态时，终端也可以先提示用户解除该锁屏状态，再进行 后续处理，请参阅图2，本发明实施例中防止终端丢失的方法另一个实施例包括：
201、当终端在锁屏状态下检测到耳机插入时，该终端置耳机插入无效，保持外放扬声器有效；
可以理解的是，目前在同时又耳机插口与扬声器的终端中，当没有耳机插入时，扬声器有效，采用外放扬声器作为音频输出，当耳机插入时，会将外放扬声器置无效，使该外放扬声器不再作为音频输出，仅使用插入的耳机作为音频输出。为了防止偷盗者插入耳机使得终端的外放扬声器无效，在终端处于锁屏状态时，若终端检测到耳机插入，终端置耳机插入无效，即这个状态下耳机插入的操作不会将外放扬声器置为无效，保持外放扬声器有效，还是采用该外放扬声器作为该终端的音频输出。
可选的，在实际应用中，在置耳机插入无效之前，终端可以先提示用户解除终端的锁屏状态，若在第一预定时间内该终端未解除锁屏状态，再触发置耳机插入无效，保持外放扬声器有效的步骤。可以理解的是，真正的用户接收到该提示后，可以很快的解除该终端的锁屏状态，而偷盗者接收到该提示后，由于不知道如何解锁，或者不知道密码等，不能立即解除该终端的锁屏状态。
终端提示用户解除终端的锁屏状态后，若在该第一预定时间内，该终端还未解除锁屏状态，则表示目前终端的使用者很可能不是真正的用户，该终端置耳机插入无效，保持外放扬声器有效。若在该第一预定时间内终端解除了锁屏状态，则表示使用者可能是真正的用户，终端可以执行该接收到的插入耳机指令。需要说明的是，上述可选步骤与步骤203和204不会同时执行。例如，若接收到特定指令，且检测到当前处于锁屏状态的同时，终端检测到耳机插入，则终端可以只执行步骤203，提示用户解除终端的锁屏状态，而不会在同一时间执行两次提示的操作。
可以理解的是，步骤201执行的时机可以在终端处于锁屏状态的整个过程中，并不限定在步骤202之前，另外，在有些场景中，比如锁屏状态时，终端没有接收到插入耳机指令，则步骤201不执行，此处不作限定。
202、当终端接收到特定指令时，所述终端检测当前是否处于锁屏状态，所述特定指令用于表示控制终端音量降低的指令和/或使终端无法接收到载波 信号的指令；
与步骤101类似，此处不作赘述。
另外，可选的，在具有内置备用电池的终端中，也可以将终端检测到电池被拔下也作为特定指令中的一个，若终端检测到电池被拔下，终端不立即断电，可以启动内置备用电池供电，并检测当前是否处于锁屏状态，再执行后续操作。
203、当检测到处于锁屏状态时，所述终端提示用户解除终端的锁屏状态；
当检测到处于锁屏状态时，该终端先提示用户解除终端的锁屏状态。
可以理解的是，终端可以通过多种方式提示用户解除锁屏状态，例如，可以直接弹出对话框，提示用户解除锁屏状态，也可以使终端震动，并语音提示用户解除锁屏状态，还可以有很多其他的方式，此处不作限定。
可以理解的是，提示用户解除终端的锁屏状态时，还可以在终端上同时显示一个倒计时，以提示用户需要在倒计时结束前完成锁屏状态的解锁。
204、若在第二预定时间内所述终端未解除锁屏状态，所述终端不执行所述特定指令，控制终端音量增大和/或利用外放扬声器播放警示音；
终端提示用户解除锁屏状态后，若在第二预定时间内该终端未解除锁屏状态，该终端不执行上述接收到的特定指令，控制终端音量增大和/或利用外放扬声器播放警示音。
可以理解的是，第一预定时间，第二预定时间均可以由出厂设置，也可以由用户自定义，且该第一预定时间与第二预定时间可以相同，也可以不同，此处不作限定。
若在第二预定时间内终端解除了锁屏状态，则终端执行该接收到的控制终端音量降低或使终端不响应的指令。
可选的，在执行控制终端音量增大步骤的方案中，为了使终端被叫铃声容易被用户听到，或使外放扬声器播放警示音的效果更好，可以控制终端音量增大至至最大，当然，在实际应用中，也可以增大音量至其他数值，例如总音量的98％，或90％等，此处不作限定。
可选的，在实际应用中，可能出现用户误操作，在未解除锁屏状态时向终端发送该类特定指令，又因紧张或时间匆忙不能在第二预定时间内解除终端的锁屏状态，以至终端播放警示音，这样的场景中，可以存在如下步骤：
当终端解除锁屏状态时，该终端停止播放警示音。
205、当检测到不处于锁屏状态时，所述终端执行所述特定指令。
与步骤103类似，此处不作赘述。
本发明实施例中，若终端在锁屏状态下接收到插入耳机指令，置耳机插入无效，保持外放扬声器有效，这样避免偷盗终端的偷盗者插入耳机使终端的外放扬声器无效而导致不能采用该外放扬声器播放警示音或播放被叫铃声，进一步的，在接收到特定指令且检测到处于锁屏状态时，不直接控制终端音量增大和/或播放警示音，先提示用户解除终端的锁屏状态，只有在第二预定时间内还未解除该锁屏状态，才控制终端音量增大和/或播放警示音，这样可以避免因用户的误操作或忘记解除锁屏状态而导致的频繁增大音量或播放警示音，极大的提升了终端的人机交互性能。
上面实施例中，终端播放警示音，在实际应用中，播放警示音的同时，终端还可以采集当前使用者相关的信息上传到服务器中，请参阅图3，本发明实施例中防止终端丢失的方法另一个实施例包括：
301、当终端在锁屏状态下检测到耳机插入时，该终端置耳机插入无效，保持外放扬声器有效；
302、当终端接收到特定指令时，所述终端检测当前是否处于锁屏状态，所述特定指令用于表示控制终端音量降低的指令和/或使终端无法接收到载波信号的指令；
303、当检测到处于锁屏状态时，所述终端提示用户解除终端的锁屏状态；
304、若在第二预定时间内所述终端未解除锁屏状态，所述终端不执行所述特定指令，控制终端音量增大和/或利用外放扬声器播放警示音；
步骤301至步骤304，与步骤201至步骤204类似，此处不作赘述。
305、终端获取当前使用者的生物特征；
终端不执行接收到的特定指令时，可以获取当前使用者的生物特征，该生物特征具体可以包括指纹，虹膜，图像等。
具体的，终端可以通过触摸屏检测当前使用者的指纹，和/或，终端可以通过摄像头拍摄当前使用者的图像，和/或，终端可以通过摄像头识别当前使用者的虹膜信息等。
或，终端可以通过，终端还可以获取当前使用者其他方面的信息，此处不作限定，且获取到的当前使用者的信息可以为上面各种信息中的一种或多种，此处不作限定。
306、将获取到的所述生物特征上传至预置的服务器中，和/或将获取到的所述生物特征发送到其他终端中；
终端获取到当前使用者的生物特征后，将获取到的该生物特征上传至预置的服务器中，和/或发送到其他终端中。
可以理解的是，该预置的服务器可以是终端所属的设备商提供的，也可以是由用户自定义的，此处不作限定。该其他终端也可以由用于预先设定。
307、终端获取当前使用者所处环境的环境参数；
终端不执行接收到的特定指令时，还可以获取当前使用者所处环境的环境参数，该环境参数具体可以包括地理位置、环境信息等、
具体的，终端可以通过内置GPS定位终端(也即当前使用者)的当前位置，和/或，终端可以通过内置的传感器(例如，温度传感器、湿度传感器，红外传感器等)获取终端附近的环境参数。
308、将获取到的所述环境参数上传至预置的服务器中，和/或将获取到的所述环境参数发送到其他终端中；
终端获取到当前使用者所处环境的环境参数后，将获取到的该环境参数上传至预置的服务器中，和/或发送到其他终端中。
可以理解的是，该预置的服务器可以是终端所属的设备商提供的，也可以是由用户自定义的，此处不作限定。该其他终端也可以由用于预先设定。
可以理解的是，步骤307和步骤308可以与步骤305和步骤306任选一种执行，或都执行，且它们之间的时序关系并不限定，例如可以获取到生物特征和环境参数后同时发送，也可以先获取到的先发送，此处不作限定。
309、当检测到不处于锁屏状态时，所述终端执行所述特定指令。
与步骤205类似，此处不作限定。
本发明实施例中，终端控制终端音量增大或播放警示音的同时，还可以获取当前使用者的生物特征或环境参数，将获取到的生物特征或环境参数上传至预置的服务器中或发送到其他终端中，这样若用户没有及时发现终端丢失，或 丢失的终端不在用户附近，用户也可以得到预置的服务器或其他终端中收到的当前使用者的生物特征或环境参数，从而寻求公安机关的帮助，以找回丢失的终端。
可以理解的是，在实际应用中，上述各实施例中防止终端丢失的方法中的执行步骤，均可以设置为在终端中某一特定功能开启后执行，例如，终端的设置选项中可以存在防丢失选项，若将该防丢失选项置为打开，则可以执行上述各实施例中防止终端丢失的方法的各步骤，若将该防丢失选项置为关闭，则可以不执行上述各步骤，按照当前终端接收到指令即执行的方式来执行。
为便于理解，下面以一具体应用场景对本发明实施例中防止终端丢失的方法方法进行具体描述：
在火车站，用户A的终端被偷盗者B偷窃；
偷盗者B为防止用户A发现终端丢失后呼叫该终端，向该终端发出关机指令；
终端接收到该关机指令后，检测到当前终端处于锁屏状态，提示用户解除终端的锁屏状态；
偷盗者B不知道解锁密码，尝试两次后均未解开该终端的锁屏状态，此时到达预置的解锁时间5秒，终端确定在5秒内未解除锁屏状态，不执行关机指令，且调节音量到最大，利用外放扬声器播放警示音；
此时偷盗者B拿出耳机，将耳机插入终端耳机插孔想不再让终端发出声音，终端接收到插入耳机指令后，提示用户解除终端的锁屏状态，偷盗者不能在预置的5秒内解除终端的锁屏状态，终端置耳机插入无效，保持外放扬声器有效，继续播放警示音；
同时，终端通过触摸屏检测偷盗者B的指纹，通过摄像头拍摄偷盗者B的图像，通过内置GPS定位偷盗者B的当前位置，将得到的信息均传送到预置的服务器中；
用户A在被偷盗后及时发现了终端丢失，并听到周围传来的警示音；
用户A立即根据警示音发出的位置找到偷盗者B，找回丢失的终端。
上面给出了一个终端被偷盗找回的场景，下面给出一个用户误操作的场景：
用户A由于操作失误，在终端处于锁屏状态时向终端发出了减小音量的指令；
终端提示用户A解除终端的锁屏状态；
第一种情况：终端在预置的5秒内解除了该终端的锁屏状态，终端执行该减小音量的操作；
第二种情况：用户A由于紧张没有在预置的5秒内解除该终端的锁屏状态，终端不执行减小音量的指令，并利用外放扬声器播放警示音；
终端播放警示音时，用户A主动解除终端的锁屏状态，终端检测到锁屏状态解除后，停止播放警示音。
下面对本发明实施例中的终端进行描述，请参阅图4，本发明实施例中终端一个实施例包括：
检测模块401，用于当接收到特定指令时，检测当前是否处于锁屏状态，所述特定指令用于表示控制终端音量降低的指令和/或使终端无法接收到载波信号的指令；
警示模块402，用于当所述检测模块401检测到处于锁屏状态时，不执行所述特定指令，控制终端音量增大和/或利用外放扬声器播放警示音。
该特定指令有很多，具体的，例如静音指令、调小音量指令均为控制终端音量降低的指令，关机指令或拔SIM卡指令为使终端无法接收到载波信号的指令，可以理解的是，还可以有其他的控制终端音量降低或使终端无法接收到载波信号的指令，此处不作限定。
本发明实施例中，当终端接收到特定指令时，检测模块401先检测当前是否处于锁屏状态，该特定指令表示控制终端音量降低的指令和/或使终端无法接收到载波信号的指令，当确定处于锁屏状态时，警示模块402不执行该特定指令，控制终端音量增大和/或利用外放扬声器播放警示音，若用户及时发现终端丢失，而附近又有警示音发出，则用户可以根据警示音发出的位置确定丢失终端的位置，从而可以找到丢失的终端，若附近没有警示音发出，由于终端处于锁屏状态时不执行控制终端音量降低和/或使终端无法接收到载波信号的指令，用户也可以通过呼叫该终端，寻找附近发出被叫铃声的终端从而确定丢失终端的位置，也可以找到丢失的终端，从而在用户及时发现终端丢失时，增 大了丢失的终端被用户找到的概率。
上面实施例中，警示模块402可以利用外放扬声器播放警示音，在实际应用中，若终端被偷盗者盗取后，偷盗者可能会插入耳机导致终端中的外放扬声器无效，为了解决该问题，终端可以在锁屏状态下检测到耳机插入时作特殊处理，请参阅图5，作为本发明实施例中终端另一个实施例，上述终端还包括：
无效模块501，用于当在锁屏状态下检测到耳机插入时，置耳机插入无效，保持外放扬声器有效。
本发明实施例中，若终端在锁屏状态下检测到耳机插入，无效模块501置耳机插入无效，保持外放扬声器有效，这样避免偷盗终端的偷盗者插入耳机使终端的外放扬声器无效而导致不能利用外放扬声器播放被叫铃声或警示音。
上面实施例中，无效模块501置耳机插入无效，保持外放扬声器有效，在实际应用中，为了达到更好的用户体验，在无效模块501置耳机插入无效，保持外放扬声器有效之前，可以先提示用户解锁，请参阅图6，作为本发明实施例中终端另一个实施例，上述无效模块501具体可以包括：
提示单元601，用于当在锁屏状态下检测到耳机插入时，提示用户解除终端的锁屏状态；
无效单元602，用于当所述提示单元601提示解除锁屏状态之后的第一预定时间内未解除锁屏状态时，置耳机插入无效，保持外放扬声器有效。
本实施例中，无效单元602置耳机插入无效，保持外放扬声器有效之前，提示单元601先提示用户解锁，增强了终端的人机交互性能。
上面实施例中，若当接收到特定指令，且检测模块401检测到为锁屏状态，警示模块402则控制终端音量增大和/或利用外放扬声器播放警示音，在实际应用中，为避免因用户误操作而频繁增大音量或播放警示音，可以不执行接收到的特定指令之前先提示解锁，请参阅图7，作为本发明实施例中终端另一个实施例，上述图4或图5所示的终端还包括：
提示模块701，用于在所述警示模块402不执行所述指令之前，提示用户解除终端的锁屏状态；
触发模块702，用于当所述提示模块701提示解除锁屏状态之后的第二预定时间内未解除锁屏状态时，触发所述警示模块402。
本发明实施例中，在接收到特定指令且检测到处于锁屏状态时，警示模块402不直接控制终端音量增大和/或播放警示音，提示模块701先提示用户解除终端的锁屏状态，只有在第二预定时间内还未解除该锁屏状态，触发模块702才触发警示模块402控制终端音量增大和/或播放警示音，这样可以避免因用户的误操作或忘记解除锁屏状态而导致的频繁增大音量或播放警示音，极大的提升了终端的人机交互性能。
上面实施例中，警示模块402控制终端音量增大和/或利用外放扬声器播放警示音，然而这只对于用户及时发现终端丢失且偷盗者在附近的场景有效，在实际应用中，在不执行接收到的特定指令时，还可以获取当前使用者的相关信息并上传，请参阅图8，作为本发明实施例中终端另一个实施例，上述终端还包括：
第一获取模块801，用于在所述警示模块402不执行所述特定指令时，获取当前使用者的生物特征；
第一发送模块802，用于将所述第一模块801获取到的所述生物特征上传至预置的服务器中，和/或，将获取到的所述生物特征发送到其他终端中；
可选的，该终端还可以包括：
第二获取模块803，用于在所述警示模块402不执行所述特定指令时，获取当前使用者所处环境的环境参数；
第二发送模块804，用于将所述第一模块801获取到的所述环境参数上传至预置的服务器中，和/或，将获取到的所述环境参数发送到其他终端中。
本发明实施例中，警示模块402不执行接收到的特定指令的同时，第一获取模块801可以获取当前使用者的生物特征，第二获取模块803可以获取当前使用者所处环境的环境参数，第一发送模块802将获取到的生物特征上传至预置的服务器中，和/或，将获取到的生物特征发送到其他终端中，第二发送模块804将获取到的环境参数上传至预置的服务器中，和/或，将获取到的环境参数发送到其他终端中，这样若用户没有及时发现终端丢失，或丢失的终端不在用户附近，用户也可以得到预置的服务器或其他终端中收到的当前使用者的信息，从而寻求公安机关的帮助，以找回丢失的终端。
上面实施例中，警示模块402可以播放警示音，在实际应用中，若为用户 误操作，一直播放警示音可能会影响用户体验，请参阅图9，作为本发明实施例中终端的另一个实施例，上述终端还包括：
停止模块901，用于在所述警示模块402利用外放扬声器播放警示音时，当锁屏状态被解除，停止播放警示音。
本实施例中，警示模块402利用外放扬声器播放警示音时，若锁屏状态被解除，停止模块901可以停止播放警示音，这样，若用户误操作使得终端播放警示音时，用户可以从容的解开锁屏状态，停止播放警示音，提高了终端的人机交互性能。
为了便于理解上述实施例，下面以上述终端各个模块在一个具体应用场景中的交互过程进行说明：
在火车站，用户A的终端被偷盗者B偷窃；
偷盗者B为防止用户A发现终端丢失后呼叫该终端，向该终端发出关机指令；
终端接收到该关机指令后，检测模块401检测到当前终端处于锁屏状态，提示模块701提示用户解除终端的锁屏状态；
偷盗者B不知道解锁密码，尝试两次后均未解开该终端的锁屏状态，此时到达预置的解锁时间5秒，终端确定在5S内未解除锁屏状态，触发模块702触发警示模块402不执行关机指令，调节音量到最大且利用外放扬声器播放警示音；
此时偷盗者B拿出耳机，将耳机插入终端耳机插孔想不再让终端发出声音，终端接收到插入耳机指令后，提示单元601提示用户解除终端的锁屏状态，偷盗者不能在预置的5秒内解除终端的锁屏状态，无效单元602置耳机插入无效，保持外放扬声器有效，继续播放警示音；
同时，第一获取模块801通过触摸屏检测偷盗者B的指纹，通过摄像头拍摄偷盗者B的图像，第二获取模块803通过内置GPS定位偷盗者B的当前位置，第一发送模块802将得到的偷盗者B的指纹和图像传送到预置的服务器中，第二获取模块803将得到的偷盗者B的当前位置发送到预设的其他终端中；
用户A在被偷盗后及时发现了终端丢失，并听到周围传来的警示音；
用户A立即根据警示音发出的位置找到偷盗者B，找回丢失的终端。
