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。
实施例一
本发明实施例提供一种移动通信系统，该系统包括：移动终端以及基站。可选地，本发明实施例提供一种基站信号发射功率的调整方法，该方法应用于该无线通信系统，图1为本发明实施例一中的基站信号发射功率的调整方法的流程示意图，参见图1所示，该基站信号发射功率的调整方法包括：
S101：基站向移动终端发送下行信号；
这里，为了实现移动终端与基站之间的通信，基站会向移动终端发送下行信号。
S102：移动终端判断下行信号的信号强度是否低于第一信号强度门限值；
这里，为了便于确定该下行信号的信号强度是否能够满足正常的通信需求，在移动终端接收到基站发送的下行信号时，首先需要判断接收到的 下行信号的信号强度是否满足预设条件，当下行信号的信号强度满足预设条件时，则表明该下行信号的信号强度不能满足正常通信需求，移动终端与基站之间不能正常通信。举例来说，采用对当前接收到的下行信号的信号强度设定第一信号强度门限值的方式，来判断该下行信号的信号强度能否满足移动终端与基站之间正常的通信需求。
S103：如果下行信号的信号强度低于第一信号强度门限值，移动终端生成功率调整指令；
举例来说，当该下行信号的信号强度低于第一信号强度门限值时，则表明下行信号的信号强度降低且该下行信号的信号强度不能满足正常通信需求，移动终端与基站之间不能正常通信，需要增大下行信号的信号强度，此时，移动终端生成功率调整指令。也就是说，只要该下行信号的信号强度满足预设条件，就可以认为需要增大下行信号的信号强度，来保证移动终端与基站之间的正常通信，此时需要基站增大自身的信号发射功率，移动终端会生成功率调整指令。其中，功率调整指令用于指示所述基站增大自身的信号发射功率。
在实际应用中，下行信号的信号强度降低，可以引起移动终端与基站之间不能正常通信，如移动终端出现掉话、网络连接失败、信息发送失败等情况。因此，需要判断下行信号的降低是否因为下行信号受到干扰而引起，那么，移动终端在下行信号的信号强度低于第一信号强度门限值之后，判断该下行信号是否受到干扰，如果下行信号受到干扰，移动终端获得干扰的干扰强度信息，最后，基于该干扰强度信息，生成对应的功率调整指令，反之，流程结束。
在具体实施过程中，如果下行信号的信号强度低于第一信号强度门限值，移动终端可以先将该下行信号进行解调，然后根据该下行信号是否包含预先设定的基站信令标志，来判断该下行信号是否受到干扰。如果该下 行信号中未包含预设基站信令标志，则表明该下行信号受到干扰；如果该下行信号中包含预先设定的基站信令标志，则表明该下行信号未受到干扰。
需要说明的是，该预设基站信令标志，可以用于表明下行信号未受到干扰。举例来说，在移动终端与基站的通信过程中，基站会在向移动终端发送的下行信号中的固定位置写入表示该预设基站信令标志的消息，如果该下行信号未受到干扰的影响，在解调时就会获得该预设基站信令标志的消息，相应地，如果该下行信号受到了干扰的影响，那么带有干扰的下行信号就与基站原始发送下行信号会有所不同，导致在解调时就无法获得该预设基站信令标志的消息。这样，移动终端通过解调下行信号，确定该下行信号是否包含预设基站信令标志的方式，就可以确定下行信号是否受到干扰。
举例来说，假设预先设定的基站信令标志为一段00000011的消息，由于在下行信号未受到干扰的影响时或者干扰不足以影响该下行信号的信号强度时，该00000011的消息就不会发生变化，那么，在解调后就可以在对应位置获得该00000011的消息，这样，就可以确定下行信号未受到干扰；但是，由于在下行信号受到干扰的影响导致下行信号的强度低于第一信号强度门限值时，该00000011的消息就会发生变化，如变成11001100的消息，那么，解调后在对应位置就找不到该00000011的消息，这样，就可以确定下行信号受到干扰。
在具体实施过程中，该预设基站信令标志的相关信息，如消息内容和放置位置可以是移动终端与基站预先通过协议确定，并通过该协议写入到基站的软件中；也可以是在移动终端首次接入到基站时才确定的，这里，本发明实施例不做具体限定。
在具体实施过程中，在确定该下行信号受到干扰之后，移动终端会获得该下行信号中携带的干扰强度信息。这里，该干扰强度信息可以用于指 示基站在增大下行信号的发射功率时确定发射功率。
举例来说，移动终端会根据当前下行信号的功率，获得该下行信号中携带的干扰强度信息。该干扰强度信息，可以是当前下行信号的功率衰减值，也可以是当前下行信号对应的干扰功率等级，还可以是其他形式的干扰强度信息。
一方面，移动终端可以直接采用当前下行信号的信号强度减去前一时刻未降低时下行信号的信号强度，而获得该下行信号的功率衰减值。例如，假设当前下行信号的信号强度为-90dBm，并假设前一时刻未降低时下行信号的信号强度为-80dBm，那么下行信号的功率衰减值为-10dB，即表明下行信号的信号强度下降了10dB。
另一方面，移动终端也可以先根据当前下行信号的信号强度，获得该下行信号的功率衰减值，再根据该功率衰减值，计算出当前下行信号对应的干扰功率等级。例如，假设移动终端中预先存储有干扰功率等级映射表，参见表1所示，根据表1可知，当下行信号的功率衰减值为-3dB时，对应的干扰功率为1级；当下行信号的功率衰减值为-9dB时，对应的干扰功率等级为2级。
Figure PCTCN2016103084-appb-000001
表1
当然，本领域技术人员在具体实施时还可以采用其他方式来获得该干扰强度信息，这里，本发明不做具体限定。
在具体实施过程中，移动终端在获得干扰强度信息之后，基于该干扰强度信息对应的生成功率调整指令。
S104：移动终端向基站发送功率调整指令；
这里，移动终端会在生成功率调整指令后，向基站发送该功率调整指令，指示基站增大自身的发射功率。
S105：基站执行功率调整指令，确定自身的信号发射功率的功率补偿值；
S106：基站按照功率补偿值，增大信号发射功率。
在具体实施过程中，S105至S106具体为：在基站接收到移动终端发送的功率调整指令后，基站会执行该功率调整指令，并确定自身的信号发射功率的功率补偿值，基站在确定功率补偿值后，会按照该功率补偿值增大自身的信号发射功率。其中，该功率补偿值，可以指示基站在增大下行信号发射功率时应增大的功率值。
在具体实施过程中，基站确定自身的信号发射功率的功率补偿值的方式可以且不限于有以下两种方式。
第一种方式，基站通过获取功率调整指令中携带的干扰强度信息的方式，来确定功率补偿值；
举例来说，基站先获取功率调整指令中携带的干扰强度信息，再按照预设规则，获得干扰强度信息对应的功率补偿值。其中，干扰强度信息用于表征移动终端的下行信号所受到的干扰的强度。
这里，根据S103中的相关描述可知，基站获取的干扰强度信息，可以是功率衰减值，也可以是干扰功率等级，还可以是其他形式的干扰强度信息。
下面针对基站获取的干扰强度信息为功率衰减值或干扰功率等级的不同情况，分别详细说明基站如何按照预设规则获得干扰强度信息对应的功率补偿值。
情况一、基站获取的干扰强度信息为功率衰减值。
在具体实施过程中，预设规则可以为一数学公式，如wb＝k*ws+σ，其中，wb表示功率补偿值，ws表示功率衰减值，k为系数，σ为预设经验值。
需要说明的是，k大于等于1，可以为整数，也可以为小数，如1、2、2.6等；σ大于等于0，可以为整数，也可以为小数，如0、1.8、10等。这里，本发明实施例不对k和σ的取值做具体限定，由本领域的技术人员在具体实施时进行调试确定。
举例来说，当k＝1且σ＝0时，即使用“衰减多少补偿多少”的原则来确定功率补偿值，也就是说，直接确定功率衰减值ws为功率补偿值wb。例如，假设基站原自身的信号发射功率为-90dBm，而基站获得的功率衰减值ws为-5dB，此时，确定基站自身的发射功率时应增大的功率值为-5dB，即基站自身的信号发射功率的功率补偿值wb为5dB，那么调整后的基站自身的信号发射功率为-85dBm。当k＝1且σ>0时，即只按照预设经验值来进行确定基站自身的信号发射功率补偿值wb。当k>1且σ＝0时，即直接使用“倍增”原则来确定功率补偿值，也就是说，确定功率补偿值为功率衰减值的多倍，如2倍、2.5倍、3倍等。当k>1且σ>0时,即在倍增的基础上，还增加一定的预设经验值进行调整。
在本发明另一实施例中，预设规则还可以为一功率衰减值补偿映射表，参见表2所示。
Figure PCTCN2016103084-appb-000002
表2
举例来说，可以在基站中预先存储功率衰减值补偿映射表，基站获取功率衰减值后，通过查询该功率衰减值补偿映射表，可以确定基站自身的 信号发射功率的功率补偿值。例如，根据表2可知，当基站获取的功率衰减值为-3dB时，对应的基站自身的信号发射功率的功率补偿值为11dB。
需要说明的是，预设规则不局限于上述两种形式，同时，当预设规则采用上述两种形式时，预设规则的具体内容也不局限于上述示例说明。
情况二、基站获取的干扰强度信息为干扰功率等级。
在具体实施过程中，上述预设规则可以为干扰等级补偿映射表，参见下表3所示。
Figure PCTCN2016103084-appb-000003
表3
举例来说，可以在基站中预先存储干扰等级补偿映射表，基站获取干扰功率等级后，通过查询该干扰等级补偿映射表，可以确定基站自身的信号发射功率的功率补偿值。例如，根据表3可知，当基站获取的干扰功率等级为2级时，对应的基站自身的信号发射功率的功率补偿值为15dB。
当然，基站获取的干扰强度信息还可以为其它信息，相应地，基站按照预设规则获得干扰强度信息对应的功率补偿值也可以为其它情况，本发明实施例不作具体限定。
第二种方式，基站通过获取功率调整指令中携带的下行信号强度的方式，来确定功率补偿值。
举例来说，基站先获取功率调整指令中携带的下行信号强度，再按照预设规则，获得该下行信号强度对应的功率补偿值。其中，该下行信号强度为移动终端所接收的下行信号的信号强度。
可选地，在基站获取下行信号强度后，可以先根据该下行信号强度确 定出功率衰减值或干扰功率等级。然后再按照预设规则，获得该下行信号强度对应的功率补偿值。本领域的技术人员可以参照第一种方式的相关描述进行实施，这里本发明实施例就不做过多赘述。
需要说明的是，无论采用哪种方式来确定基站自身的信号发射功率的功率补偿值，都需要注意增大后的基站自身的信号发射功率值不能超过基站的最大允许发射功率，还需要注意移动终端的最大接收信号强度。
至此，便完成了对基站信号发射功率的调整。由上述内容可知，本发明实施例提供的技术方案，移动终端能够在下行信号的信号强度降低时，生成功率调整指令，并向基站发送该功率调整指令请求基站增大自身的信号发射功率；然后，基站接收到该功率调整指令后，执行该功率调整指令，确定自身的信号发射功率的功率补偿值，最后，基站按照该功率补偿值增大自身的信号发射功率。因此，可以实现根据移动终端接收到的当前下行信号的信号强度来实时增大基站自身的信号发射功率，从而实时提高移动终端的信号强度，保证移动终端与基站之间的正常通信，进而提供了良好的用户体验。
实施例二
基于前述实施例，在实际应用中，为了减少不必要的信令开销和处理过程，移动终端在判断上述下行信号是否受到干扰之前，还可以先判断该移动终端自身是否进入基站的信号盲区。
那么，图2为本发明实施例二中的基站信号发射功率的调整方法的流程示意图，参见图2所示，执行S101之后，S102可以包括：
S201：移动终端判断下行信号的信号强度是否高于第二信号强度门限值；
这里，第二信号强度门限值低于上述第一信号强度门限值。
S202：如果下行信号的信号强度高于第二信号强度门限值，判断下行 信号的信号强度是否低于第一信号强度门限值。
这里，移动终端可以判断接收到的下行信号的信号强度是否高于第二信号强度门限值，以此来判断该移动终端是否进入基站的信号盲区。当下行信号的信号强度低于或者等于第二信号强度门限值，也就是该移动终端确定自身进入到基站的信号盲区时，移动终端可以确定导致下行信号的信号强度降低的原因并非由于干扰引起，那么，此时，移动终端等待基站针对信号盲区进行发射功率的补偿；反之，当下行信号的信号强度高于第二信号强度门限值，也就是该移动终端确定自身未进入到基站的信号盲区时，移动终端可以进一步去判断下行信号的信号强度是否低于第一信号强度门限值，进而再依次执行S103至S106。
