具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
随着移动通信技术的发展，移动通信已经经历了2G、3G以及4G等多个版本的发展。而不论是早期2G时代的GSM(Global System for Mobile Communication)移动通信系统或者CDMA(Code Division Multiple Access)通信系统，还是到了后面4G时代的LTE系统架构，基站都是比较重要的一个通信设备。
例如，如图1所示的2G移动通信系统架构示意图。基站BTS作为移动通信通络的的接入设备与BSC(Base Station Controller)连接，然后BSC再与MSC连接。再例如图2所示的4G移动通信系统架构示意图。基站eNB与MME(Mobility Management Entity)连接，而MME与服务网关Serving Gateway连接。可以从图1和图2看出，在移动通信系统中，基站作为直接与移动终端建立连接的设备，在整个系统架构中有着比较重要的地位。基站，一般是指“公用移动通信基站”，其作用主要用于给手机、平板电脑等移动终端提供信号。而随着通信技术的发展，发明人发现出现了伪基站。
伪基站即假基站，设备一般由主机和笔记本电脑组成，通过短信群发器、短信发信 机等相关设备能够搜取以其为中心、一定半径范围内的手机卡信息，利用2G移动通信的缺陷，通过伪装成运营商的基站，冒用他人手机号码强行向用户手机发送诈骗、广告推销等短信息。
伪基站设备运行时，移动终端发送的无线信号被强制连接到该设备上，导致移动终端无法正常使用运营商提供的服务，移动终端一般会暂时脱网8～12秒后恢复正常，部分移动终端则必须开关机才能重新入网。此外，它还会导致移动终端用户频繁地更新位置，使得该区域的无线网络资源紧张并出现网络拥塞现象，影响用户的正常通信。
因此，发明人提出了本申请中可以提升移动终端的信息的安全性，减小接入到伪基站的伪基站识别方法、装置以及移动终端。
下面将结合附图具体描述本申请的各实施例。
请参阅图3，本申请提供的一种伪基站识别方法，应用于移动终端，所述方法包括：
步骤S110：移动终端获取所探测到的基站的TAC值。
通常，网络空中接口用于实现移动终端和移动通信网络的基站之间的信息交互，并且网络空中接口上的信息由各种逻辑信道承载。其中，逻辑信道分为业务信道(TCH，Traffic Channel)和控制信道(CCH，Control Channel)两大类，其中，TCH主要在网络和移动终端间的传送业务，如语音、数据等；CCH是用于传送信令信息和短的分组数据的信道，CCH中广播信道(BCH，Broadcast Channel)用于通过广播的方式传输信息，在BCH中的广播控制信道(BCCH，Broadcast Control Channel)用于基站向移动终端广播公用的信息，例如系统消息等。
那么移动终端在探测基站的过程中，会检测基站广播的系统信息，进而从系统消息中解析出基站的TAC值。具体的，以LTE移动通信系统为例，LTE基站所广播的系统信息被分为两大类：MasterInformationBlock(MIB)消息和多个SystemInformationBlocks(SIBs)消息。MIB消息在PBCH中传输，不使用RNTI加扰；而SIB消息是在PDSCH中传输，使用SI-RNTI加扰。当网侧设备(LTE基站)开机后，会先发送MIB消息，然后再发送一系列的SIB消息，而不同的SIB携带不同的参数。例如，SIB1：主要携带小区接入和小区选择相关信息，以及LTE-TDD子帧配置、其他SIB块的调度和窗口信息等。SIB2：主要携带公共的无线资源配置相关信息，包括接入BAR信息、PRACH配置信息、上行频点信息、MBSFN配置等。SIB3：携带同频、异频、跨制式小区重选相关的公共信息。SIB4：携带用于同频小区重选的邻区信息。SIB5：携带用于异频小区重选的邻区信息。SIB6：携带用于跨制式(UTRA)小区重选的邻区信息。SIB7：携带用于跨制式(GERAN)小区重选的邻区信息。SIB8：携带用于跨制式(CDMA2000)小区重选的邻区信息。SIB9：携带HOME eNB(HNB)的相关信息。SIB10/11：携带ETWS(Earthquake and Tsunami Warning System)的相关信息。当UE从寻呼消息中解码发现有ETWS消息存在时，就需要从SIB10/11中获取具体的ETWS内容。
SIB12：携带CMAS(Commercial Mobile Alerting System)的相关信息。当UE从寻呼消息中解码发现有CMAS消息存在时，就需要从SIB12中获取具体的CMAS内容。SIB13：携带MBMS(Multimedia Broadcast Multicast Service)的相关信息。其中，那么移动终端可以从SIB1中获取到基站的TAC(Tracking Area Code)值。
其中，跟踪区(Tracking Area)是LTE系统为UE(移动终端)的位置管理设立的概念。跟踪区的功能与3G系统的位置区(LA)和路由区(RA)类似。通过跟踪区信息核心网络能够获知处于空闲态的UE的位置，并且在有数据业务需求时，对UE进行寻呼。而一个跟踪区可包含一个或多个小区，而一个小区只能归属于一个跟踪区，那么跟踪区的标识即为本申请中的TAC值。
其中，作为一种方式，TAC的标识为TAI(Tracking Area Identity)，TAI由PLMN和TAC组成。TAI＝PLMN+TAC。
其中，作为一种方式，若移动终端为Android操作系统的情况下，移动终端可以调用TelephonyManager类来获取移动终端从已经解析出的系统消息中的数据。
步骤S120：获取参考TAC值，所述参考TAC值为合法基站的TAC值。
需要说明的是，在本申请中，获取参考TAC值的目的是为了将其与移动终端当前探测到的基站的TAC值进行比对，以便根据比对结果来判断所探测到的基站是否为伪基站。那么在这种情况下，所获取的参考TAC值可以为合法基站的TAC值。
可以理解的是，通常基站的TAC值为按照一定的规则配置。例如，属于同一个跟踪区的多个基站的TAC值可以配置为相同或者是近似。而不同的是，伪基站的TAC值通常会交大。
那么作为一种方式，移动终端可以预先存储所有的合法基站的TAC值。例如，可选的，移动终端中可以分区域存储所有的合法基站的TAC值。其中，该区域可以为根据经纬度等位置信息自己定义的区域，也可以为行政区域。在移动终端检测到自己所处的前述区域发生改变时，就可以根据当前所在的区域从新确定参考TAC值。例如，移动终端当前处于A区域，那么移动终端会将配置在A区域的合法基站的TAC值作为参考TAC值。而当移动终端从A区域移动到B区域以后，移动终端会将配置在B区域的合法基站的TAC值作为参考TAC值。
需要说明的是，在存储基站TAC值时，可以将TAC值和基站的位置信息对应存储，那么在所在区域的基站TAC值有多个的情况下，移动终端可以根据基站的位置信息确定多个基站中与移动终端最近的一个基站的TAC值作为参考TAC值。
步骤S130：将所述所探测到的基站的TAC值与所述参考TAC值进行比对。
可选的，移动终端在比对所探测到的基站的TAC值与所述参考TAC值的过程中，可以直接将所探测到的基站的TAC值与所述参考TAC值进行数学意义上的差值，也可以将所探测到的基站的TAC值与所述参考TAC值所包括数据的位数进行数学意义上的差值。
步骤S140：若所述所探测到的基站的TAC值与所述参考TAC值的差值满足目标条件，判断所述所探测到的基站为伪基站。
根据前述的内容可知，伪基站的TAC值相较于合法基站的TAC值会较大。那么通过比较所探测到的基站的TAC值与参考TAC值之间的差值即可判断所探测到基站是否为伪基站。
作为一种方式，所述目标条件包括以下条件中的至少一个：所探测到的基站的TAC值与参考TAC值的差值大于设定门限值；以及所探测到的基站的TAC值与参考TAC值的差值在目标区间段内。需要说明的是，该目标区间段的最小值大于前述设定门限值。
其中，移动终端可以实时根据当前所处的环境来确定目标条件所包括的内容。该环境可以为无线环境也可以为位置环境等。
例如，移动终端可以根据所探测到的基站所广播的无线信号的强度来确定定目标条件所包括的内容。
可以理解的是，伪基站为了吸引移动终端接入，会以较大的功率广播无线信号，那么作为一种方式，移动终端在检测到所探测的基站广播的无线信号强度大于阈值强度后，将目标条件设定为包括所探测到的基站的TAC值与参考TAC值的差值大于设定门限值或所探测到的基站的TAC值与参考TAC值的差值在目标区间段内，以便使得移动终端能够更倾向于将该基站判定为伪基站，从而最大程度的保证移动终端的信息安全。
作为另外一种方式，若移动终端在检测到所探测的基站广播的无线信号强度不大于阈值强度，那么将目标条件设定为同时包括所探测到的基站的TAC值与参考TAC值的差值大于设定门限值以及所探测到的基站的TAC值与参考TAC值的差值在目标区间段内。可以理解的是，若所探测到的基站所广播为无线信号强度不大于阈值强度的情况下，该基站为伪基站的概率小于所广播的无线信号强度大于阈值强度的基站为伪基站的概率。从而通过将目标条件设定为包括更多限制条件的方式来提升识别伪基站的准确率，以避免将合法基站识别为伪基站。
此外，除了前述的移动终端根据无线环境来确定目标条件所包括的内容外。还可以根据当前所处的地理位置来确定目标条件所包括的内容。
例如，若移动终端处于固定位置或者以较慢的速度移动的情况下，容易接入到所探测到的基站中。而如果移动终端处于高速移动状态，那么即使移动终端所探测到的基站为伪基站，也因为自己较高的移动速度而不会接入，进而驻留。
那么在这种情况下，移动终端若检测到自身的移动速度大于速度阈值，那么移动终端将目标条件设定为同时包括所探测到的基站的TAC值与参考TAC值的差值大于设定门限值以及所探测到的基站的TAC值与参考TAC值的差值在目标区间段内。而若移动终端若检测到自身的移动速度不大于速度阈值，移动终端可以将目标条件设定为包括所探测到的基站的TAC值与参考TAC值的差值大于设定门限值或所探测到的基站的TAC值与参考TAC值的差值在目标区间段内。
通过前述根据当前所处的环境来确定目标条件所包括的内容的方式，使得移动终端可以灵活的确定目标条件所包括的内容，进而使得目标条件可以有适应性的改变。
需要说明的是，若将伪基站的TAC值也配置为与合法基站的TAC值近似，那么可能会造成移动终端误将伪基站识别为合法基站，那么作为一种方式，若所述所探测到的基站的TAC值与所述参考TAC值的差值满足目标条件，判断所述所探测到的基站为疑似伪基站；获取所述疑似伪基站的cell id；若所述cell id不符合目标格式，判断所述疑似伪基站为伪基站。
本申请提供的一种伪基站识别方法，移动终端获取所探测到的基站的TAC值，以及获取参考TAC值，所述参考TAC值为合法基站的TAC值，然后将所述所探测到的基站的TAC值与所述参考TAC值进行比对，若所述所探测到的基站的TAC值与所述参考TAC值的差值 满足目标条件，判断所述所探测到的基站为伪基站，从而使得移动终端可以减小接入到伪基站中的概率，以避免移动终端中存储的用户信息被盗取，提升了移动终端的信息的安全性。
请参阅图4，本申请提供的一种伪基站识别方法，应用于移动终端，所述方法包括：
步骤S210：移动终端获取所探测到的基站的TAC值。
步骤S220：确认所述移动终端当前的小区连接阶段，所述小区连接阶段包括小区搜索阶段或者小区重选阶段。
可以理解的是，移动终端一开机或者从飞行模式中转换为在线模式就是开始小区搜索，在小区搜索的过程中会在可能存在移动网络(例如LTE网络)的小区的几个中心频点上接收数据并计算带宽RSSI，以接收信号强度来判断这个频点周围是否可能存在小区，如果移动终端能保存上次关机时的频点和运营商信息，则开机后可能会先在上次驻留的小区上尝试驻留；如果没有先验信息，则很可能要全频段搜索，发现信号较强的频点，再去尝试驻留。
而小区重选(cell reselection)指移动终端在空闲模式下通过监测邻区和当前小区的信号质量以选择一个最好的小区提供服务信号的过程。当邻区的信号质量及电平满足S准则且满足一定重选判决准则时，终端将接入该小区驻留。
移动终端成功驻留后，将持续进行本小区测量。RRC层根据RSRP测量结果计算Srxlev(S准则)，并将其与Sintrasearch(同频测量启动门限)和Snonintrasearch(异频/异系统测量启动门限)比较，作为是否启动邻区测量的判决条件。
步骤S230：根据所确定的小区连接阶段获取参考TAC值。
根据前述内容可知，移动终端在和基站连接的过程中可能会有多个不同的阶段。而若不同的阶段均采用相同的参考TAC值，可能会造成无法准确的识别伪基站。例如，若移动终端在A区域转换到关机状态，而又到B区域才开始切换到开机状态，或者说在A区域切换到飞行模式，而又到B区域才开始切换为在线模式，那么在这种情况下，移动终端在A区域处于开机状态或者切换为在线模式后，所获取到的参考TAC值有可能会B区域基站的TAC值，而不同区域的基站的TAC值配置可能会有区别，进而会造成无法准确的识别伪基站。
作为一种方式，本实施例中移动终端所确定的参考TAC值为从成功注册过程的合法基站的TAC中中进行选择。
那么在这种情况下若检测到移动终端处于小区搜索阶段，将所述移动终端在设定时间段内成功注册过的合法基站中，距离移动终端的当前位置最近的基站的TAC值作为参考TAC值。
可以理解的是，移动终端在从关机切换为开机或者从飞行模式切换为在线模式后，会开始小区搜索。那么在这种情况下，作为一种避免因为移动终端因为地域的改变而造成误识别伪基站的方式，移动终端可以将将所述移动终端在设定时间段内成功注册过的合法基站中，距离移动终端的当前位置最近的基站的TAC值作为参考TAC值。
若检测到移动终端处于小区重选阶段，将所述移动终端最近一次成功注册过的基站的TAC值作为参考TAC值。
可以理解的是，若移动终端处于小区重选的阶段的过程中，所探测到的基站为与当前所驻留的基站相邻的基站，那么可以直接将所述移动终端最近一次成功注册过的基站的TAC值作为参考TAC值。
需要说明的是，作为一种方式，移动终端在检测到将要转换为关机状态或者飞行模式时，可以存储当前的位置信息，而在处于开机状态或者切换为在线模式后再次采集当前的位置信息，将当前采集的位置信息和之前存储的位置信息进行比较，若位置变化距离大于阈值距离，那么又若检测到移动终端处于小区搜索阶段的情况下，将所述移动终端在设定时间段内成功注册过的合法基站中，距离移动终端的当前位置最近的基站的TAC值作为参考TAC值。而若移动终端检测的位置变化距离不大于阈值距离，可以依然采用将所述移动终端最近一次成功注册过的基站的TAC值作为参考TAC值。
其中，阈值距离可以为一个基站所覆盖范围的半径，也可以为一个跟踪区所覆盖范围的半径。其中可以理解的是，为了便于计算可以将基站或者跟踪区所实际覆盖的范围近似抽象为一个圆形区域，进而便于计算器所覆盖范围的半径。
步骤S240：将所述所探测到的基站的TAC值与所述参考TAC值进行比对。
步骤S250：若所述所探测到的基站的TAC值与所述参考TAC值的差值满足目标条件，判断所述所探测到的基站为伪基站。

请参阅图5，本申请提供的一种伪基站识别方法，应用于移动终端，所述方法包括：
步骤S310：移动终端获取所探测到的基站的TAC值。
步骤S320：获取参考TAC值，所述参考TAC值为合法基站的TAC值。
步骤S330：获取所有合法基站的TAC值。
作为一种方式，获取所述移动终端的位置；获取目标区域，所述目标区域为与所述移动终端的位置之间的距离小于阈值的区域；获取目标区域内所有合法基站的TAC值。
可以理解的是，类似于前述内容所述，基站的TAC值为按照一定的规则配置。例如，属于同一个跟踪区的多个基站的TAC值可以配置为相同或者是近似。而不同的是，伪基站的TAC值通常会交大。
那么作为一种方式，移动终端可以预先存储所有的合法基站的TAC值。例如，可选的，移动终端中可以分区域存储所有的合法基站的TAC值。其中，该区域可以为根据经纬度等位置信息自己定义的区域，也可以为行政区域，甚至可以为一个跟踪区。
作为另外一种方式，移动终端还可以向当前所驻留的小区所属的基站发送TAC值获取请求，所述TAC值获取请求用于触发所述当前所驻留的小区所属的基站向目标服务器请求所有 合法基站的TAC值；接收所述当前所驻留的小区所属的基站发送的所有合法基站的TAC值，所有合法基站的TAC值由所述目标服务器返回给所述当前所驻留的小区所属的基站。此外，在移动终端当前连接有其他的AP(WirelessAccessPoint)的情况下，移动终端还可以通过所连接的其他的AP来向目标服务器发送TAC值获取请求。
需要说明的是，目标服务器中可以为移动通信服务提供商的服务器，在该服务器中存储有所有的基站的TAC值。此外，该目标服务器也可以为其他的服务器。
在移动终端检测到自己所处的前述区域发生改变时，例如，检测到所述移动终端的位置移动超过目标距离后，就可以根据当前所在的区域从新确定参考TAC值。例如，移动终端当前处于A区域，那么移动终端会将配置在A区域的合法基站的TAC值作为参考TAC值。而当移动终端从A区域移动到B区域以后，移动终端会将配置在B区域的合法基站的TAC值作为参考TAC值。
而在同一个跟踪区的基站配置不同TAC值或者至少2个基站的TAC值不同的情况下，基站在广播系统消息时，可以将与广播系统的基站同属于一个跟踪区的基站的TAC值也广播给移动终端，进而移动可以存储一个TA列表用于存储一个基站广播的系统消息中所携带的所有TAC值，那么在移动终端在该广播的系统消息的基站可以成功注册的情况下，可以将该列表中存储的所有TAC值作为所有合法基站的TAC值。
需要说明的是，在存储基站TAC值时，可以将TAC值和基站的位置信息对应存储，那么在所在区域的基站TAC值有多个的情况下，移动终端可以根据基站的位置信息确定多个基站中与移动终端最近的一个基站的TAC值作为参考TAC值。
步骤S340：判断所述所有合法基站的TAC值中是否存在所探测到的基站的TAC值。
步骤S350：若所述合法基站的TAC值中不存在所探测到的基站的TAC值，判断所述所探测到的基站为伪基站。
步骤S360：若所述合法基站的TAC值中存在所探测到的基站的TAC值，将所述所探测到的基站的TAC值与所述参考TAC值进行比对。
步骤S370：若所述所探测到的基站的TAC值与所述参考TAC值的差值满足目标条件，判断所述所探测到的基站为伪基站。
