基于上述移动终端硬件结构，提出本发明移动终端网络重选控制方法及装置各个实施例。
如图2所示，本发明第一实施例提出一种移动终端网络重选控制装置，该移动终端网络重选控制装置包括：
搜网模块11，配置为对GSM网络进行重选邻区测量，并将各频段的网络按照信号强度进行排列，以进行联网注册；
本发明实施例提供的移动终端网络重选控制装置主要应用在移动终端中，用于对在GSM网络环境下对移动终端通信的网络进行选择。具体地，该移动终端优选为手机，以下各实施例中以该移动终端是手机为例进行详细说明。
确定模块12，配置为当满足预设的重选条件时，根据各频段的网络按照信号强度确定待注册的网络频段；
本实施例中，上述网络重选是指X2G网络重选，即GSM网络重选。具体地，根据手机当前接收的网络信号状态，手机可以在2G、3G和4G网络之间进行切换，在切换的过程中需要进行网络重选，本发明实施例是指，在3G或4G网络状态下切换至2G网络时，所进行的网络重选操作。在进行网络重选前首先对小区网络测量，具体地，本实施例中是对GSM网络进行重选邻区测量，并将各频段的网络按照信号强度进行排列。当确认当前网络状态满足预设的重选条件时，根据排列的顺序选择确认待注册的网络频段，该网络频段是指GSM网络对应的网络频段。
可以理解的是，上述预设的重选条件可以根据实际需要进行设置，在现有的手机中通常设有算法判断条件，从而判断当前的网络状态是否满足重选条件，在此，对上述重选条件不做进一步地限定说明。
第一判断模块13，配置为当待注册的网络频段为GSM频段，判断待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册；
控制模块14，配置为当待注册的基站为首次发送位置更新注册请求时，以错误的用户识别码设定位置更新注册请求中预置参数，并将位置更新注册请求发送至待注册的基站；
具体地，手机在进行小区重选和开机搜网时，需要向基站发起位置更新注册。只有当手机在真基站上进行注册后，才可以进行数据业务(网络数据通信)以及语音业务(例如，语音通话、短信收发等)。在注册的过程中由于基站需要对手机进行识别，确定是否为非法用户，若为非法用户，则基站将会拒绝手机注册。由此，本发明实施例通过开机搜网注册和小区重选注册流程中识别伪基站。当选择确认待注册的网络频段是GSM频段时，需要对待注册的基站是否为伪基站进行识别。
伪基站通常是通过工程手机获得手机上邻小区BCCH(Broadcast Control Channel，广播控制信道)频率和场强信息，选定信号最弱的小区进 行伪装；然后根据GSM小区选择和重选算法，伪基站小区生成极大的C2值，以吸入周围的用户手机驻留(即手机接入该伪基站组建的GSM网络)。此时，伪基站可以获得用户TMSI/IMSI/IMEI等网络底层信息，最后设置任意主叫号码通过SDCCH信道发送向用户发送信息(例如，诈骗短信)。因此，伪基站不与真正的移动网络互联，当用户手机接入到伪基站后，用户无法拨通真正的用户，也无法给真正用户和网站发送信息和数据。
本实施例中，上述用户识别码为基站用于识别用户是否为非法用户的参数，可以理解的是，在不同的协议代码下用户识别码的内容不同。具体地，该用户识别码包括IMSI(International Mobile Subscriber Identification Number，国际移动用户识别码)、IMEI(International Mobile Equipment Identity，国际移动设备标识)、TMSI(Temporary Mobile Subscriber Identity，临时识别码)和IMEISV(International Mobile Equipment Identity Software Version)中的一种。
具体地，当用户确定待注册的网络频段对应的基站后，则向该基站发送位置更新注册请求，此时将判断用户是否首次向该基站发送位置更新注册请求，若是，则以错误的用户识别码设定位置更新注册请求中预置参数形成特定的位置更新注册请求，然后将该特定的位置更新注册请求发送至基站。可以理解的是，上述错误的用户识别码用于在基站上进行非法用户识别时，识别失败。具体地，该错误的用户识别码的设置方式可以根据实际需要进行设置，例如可以修改用户识别码的位数或者在正确的用户识别码上增加一个固定值(如加1)等，其具体地实现方式在此不做进一步的限定。若待注册的基站为非首次注册，则按照正常的注册流程进行位置更新注册，正常的位置更新注册流程在此不作进一步地说明。
第二判断模块15，配置为判断在第一预设时间段内是否接收到待注册的基站根据位置更新注册请求发送的第一拒绝注册信息；
处理模块16，配置为当在第一预设时间段内接收到第一拒绝注册信息时，根据正确的用户卡识别码向待注册基站重新注册；当在第一预设时间段内未接收到第一拒绝注册信息时，重新搜网，并根据搜索到的网络重新确定待注册的网络频段，以重启注册流程。
本实施例中，当待注册基站接收到上述位置更新注册请求时，将会根据该位置更新注册请求中预置参数获取用户识别码。由于此时接收到的用户识别码为错误的识别码，因此待注册的基站在进行用户识别时，将认定当前注册的手机为非法用户，此时将拒绝该手机注册，与此同时将向手机发送第一拒绝注册信息。基于上述注册原理，通过手机在根据错误的用户识别码发送位置更新注册请求后，判断在第一预设时间段内是否接收到基站返回的第一拒绝注册信息的结果即可实现对基站的真伪鉴别。具体地，若在第一预设时间段内接收到待注册的基站根据位置更新注册请求发送的第一拒绝注册信息，则确定上述待注册的基站为真基站；若在第一预设时间段内没有接收到待注册的基站根据位置更新注册请求发送的第一拒绝注册信息，则确定上述待注册的基站为伪基站。可以理解的是，上述第一预设时间段的时间长度可以根据实际需要进行设置，在此不做进一步地限定。
当通过识别认定为真基站后，可以按照正常的注册流程在该待注册的基站上进行注册，即在本实施例中，可以根据正确的用户卡识别码向待注册基站重新注册。
在确定待注册的基站为伪基站时，搜索网络，并将搜索到各频段的网络按照信号强度排列，以进行联网注册；在确定待注册的网络频段时，判断待注册的网络频段是否为GSM频段；当待注册的网络频段为GSM频段时，重新按照待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册执行相应的判断，并根据判断的结果重新完成注册流程。即当重新选定的待注册基站之前已经注册过，则按照正常的注册流程进行注册； 若重新选定的待注册基站之前未注册过，则按照本方案注册流程进行注册，以对该基站是否为伪基站进行识别。
本发明实施例通过对GSM网络进行重选邻区测量，并将各频段的网络按照信号强度进行排列，以进行联网注册；当满足预设的重选条件时，根据各频段的网络按照信号强度确定待注册的网络频段；判断待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册；当待注册的基站为首次发送位置更新注册请求时，以错误的用户识别码设定位置更新注册请求中预置参数，并将位置更新注册请求发送至待注册的基站；判断在第一预设时间段内是否接收到待注册的基站根据位置更新注册请求发送的第一拒绝注册信息；若是，则根据正确的用户卡识别码向待注册基站重新注册；若否，则重新搜网，并根据搜索到的网络重新确定待注册的网络频段，以重启注册流程。由于在移动终端进行X2G网络重选时对待注册的网络频段是否为伪基站频段进行了判断，从而可以防止移动终端进行X2G网络重选时连入伪基站，因此提高了移动终端在X2G网络重选过程中接入GSM网络进行通信的状态下使用的安全性。
在本发明实施例一实施方式中，参照图3，基于上述实施例，本实施例中，上述移动终端网络重选控制装置包括：
搜网模块11，配置为对GSM网络进行重选邻区测量，并将各频段的网络按照信号强度进行排列，以进行联网注册；
确定模块12，配置为当满足预设的重选条件时，根据各频段的网络按照信号强度确定待注册的网络频段；
第一判断模块13，判断待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册；
控制模块14，配置为当待注册的基站为首次发送位置更新注册请求时，以错误的用户识别码设定位置更新注册请求中预置参数，并将位置更新注 册请求发送至待注册的基站；
第二判断模块15，配置为判断在第一预设时间段内是否接收到待注册的基站根据位置更新注册请求发送的第一拒绝注册信息；
发送模块17，配置为当在第一预设时间段内未接收到第一拒绝注册信息的情况下，且在接收到待注册基站根据位置更新注册请求发送的鉴权请求时，根据第一预置算法得到错误的鉴权验证信息发送至待注册的基站；
第三判断模块18，配置为判断在第二预设时间段内是否接收到待注册的基站根据错误的鉴权验证信息发送的第二拒绝注册信息；
处理模块16，配置为当在第一预设时间段内接收到第一拒绝注册信息时或者当在第二预设时间段内接收到第二拒绝注册信息时，根据正确的用户卡识别码以及第二预置算法得到正确的鉴权验证信息向待注册基站重新注册；当在第二预设时间段内未接收到第二拒绝注册信息或者当在第一预设时间段内未接收到第一拒绝注册信息的情况下未接收到待注册基站根据位置更新注册请求发送的鉴权请求时，重新搜网，并根据搜索到的网络重新确定待注册的网络频段，以重启注册流程。
如图4和图5所示，在真基站上进行注册时，若以错误的用户识别码发送位置更新注册请求后，基站将会将该位置更新注册请求发送至核心网，核心网可以在此时通过基站向手机发送第一拒绝注册信息；此外，核心网还可以在此不进行拒绝注册，在后续鉴权的过程中拒绝注册。此时核心网将通过基站向手机发送鉴权请求，该鉴权请求中携带有预置的鉴权参数。在手机接收到基站所发送的鉴权请求时，将根据该鉴权请求与第一预置算法得到错误的鉴权验证信息，然后发送至待注册基站。在真基站上可以由基站将该错误的鉴权验证信息发送给核心网进行鉴权认证，从而确定鉴权识别，并由核心网通过该真基站向手机发送第二拒绝注册信息，以拒绝真基站的注册；若假基站接收到该错误的鉴权验证信息，由于无法进行鉴权 识别，通常直接接受注册，以将该注册的手机驻留在基站上。基于上述原理，可以通过判断手机是否接收到待注册的基站根据错误的鉴权验证信息发送的第二拒绝注册信息，从而确定上述待注册的基站是否为真基站。
可以理解的是，上述第二预设时间段的时间长度可以根据实际需要进行设置，在此不作进一步地限定。
具体地，上述第一拒绝注册信息和第二拒绝注册信息的内容均可以根据实际需要进行设置，在此不再详述。
应当说明的是，由于真基站在发送拒绝注册信息的时间点不同，本实施例中当手机第一次同一待注册的基站上进行注册的情况下，在进行鉴权时，仍然发送错误的鉴权验证信息，从而可以双层保证基站识别的准确性。需要在此解释的是，对于错误的鉴权验证信息的计算方式可以根据实际需要进行设置，例如可以不采用上述鉴权请求中的鉴权参数，也可以改变鉴权计算的算法表达式。其具体地改变方式在此不作进一步地限定。
在本发明实施例一实施方式中，参照图6，基于上述实施例，本实施例中，上述移动终端网络重选控制装置包括：
搜网模块11，配置为对GSM网络进行重选邻区测量，并将各频段的网络按照信号强度进行排列，以进行联网注册；
确定模块12，配置为当满足预设的重选条件时，根据各频段的网络按照信号强度确定待注册的网络频段；
第一判断模块13，配置为当待注册的网络频段为GSM频段，判断待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册；
控制模块14，配置为当待注册的基站为首次发送位置更新注册请求时，以错误的用户识别码设定位置更新注册请求中预置参数，并将位置更新注册请求发送至待注册的基站；
第二判断模块15，配置为判断在第一预设时间段内是否接收到待注册 的基站根据位置更新注册请求发送的第一拒绝注册信息；
处理模块16，配置为当在第一预设时间段内接收到第一拒绝注册信息时，根据正确的用户卡识别码向待注册基站重新注册；当在第一预设时间段内未接收到第一拒绝注册信息时，重新搜网，并根据搜索到的网络重新确定待注册的网络频段，以重启注册流程；
第四判断模块19，配置为判断待注册的网络频段是否为伪基站频段；当待注册的网络频段为伪基站频段时，触发处理模块16根据信号强度排列顺序重新确定待注册的网络频段；当待注册的网络频段为真基站频段时，触发第一判断模块13执行判断待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册操作。
当选择确认待注册的网络频段是GSM频段时，则可以根据预设的规则判断该待注册的网络频段是否为伪基站频段。在本实施例中，对于该预设的规则可以采用多种形式，例如采用白名单的形式，也可以采用黑名单的形式进行判断。以下将以采用黑名单的形式进行详细说明。例如可以根据之前统计的伪基站频段进行标记建表，并存储在手机当中形成预存的伪基站频段表。在进行伪基站频段判断时，上述第四判断模块19具体配置为：判断在预存的伪基站频段表中是否存在待注册的网络频段；若存在，则确定待注册的网络频段为伪基站频段；若不存在，则确定待注册的网络频段为真基站频段。
可以理解的是，由于不同的用户对应有不同的需求，在本实施例中还可以设置特定的模式，以确定在移动终端在基站上注册时，是否对当前注册的基站为伪基站进行判断。具体地，本实施例提供移动终端开机注册网络的控制方法与上述移动终端开机注册网络的控制方法的区别在于，还包括第五判断模块，判断是否进入伪基站识别模式；上述第一判断模块13具体配置为当移动终端进入伪基站识别模式下，判断待注册的网络频段对应 的基站是否为首次发送位置更新注册请求进行注册。
在本实施例中，可以输出一个显示界面供用户输入是否需要进行伪基站识别。当用户选择需要进入伪基站识别时，控制手机进入伪基站识别模式，此时每当切换到新的GSM网络中时，则在手机向基站进行注册时，对当前注册的基站进行识别。由于对基站进行鉴权的过程本身存在延时的问题，因此没有必要时时刻刻对注册的基站进行鉴权，毕竟伪基站出现概率小，用户在进行重要操作时进行鉴权即可。因此在本实施例中，对手机的是否进行鉴权设置了专有的模式，可以提高鉴权操作的灵活性。
如图7所示，提出了本发明移动终端网络重选控制方法的第一实施例，该移动终端网络重选控制方法包括：
步骤S110，对GSM网络进行重选邻区测量，并将各频段的网络按照信号强度进行排列，以进行联网注册；

本实施例中，上述网络重选是指X2G网络重选，即GSM网络重选。具体地，根据手机当前接收的网络信号状态，手机可以在2G、3G和4G网络之间进行切换，在切换的过程中需要进行网络重选，本发明实施例是指，在3G或4G网络状态下切换至2G网络时，所进行的网络重选操作。在进行网络重选前首先对小区网络测量，具体地，本实施例中是对GSM网络进行重选邻区测量，并将各频段的网络按照信号强度进行排列。当确认当前网络状态满足预设的重选条件时，根据排列的顺序选择确认待注册的网络频段， 该网络频段是指GSM网络对应的网络频段。
可以理解的是，上述预设的重选条件可以根据实际需要进行设置，在现有的手机中通常设有算法判断条件，从而判断当前的网络状态是否满足重选条件，在此，对上述重选条件不做进一步地限定说明。
步骤S130，判断待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册；
步骤S140，当待注册的基站为首次发送位置更新注册请求时，以错误的用户识别码设定位置更新注册请求中预置参数，并将位置更新注册请求发送至待注册的基站；
具体地，手机在进行小区重选和开机搜网时，需要向基站发起位置更新注册。只有当手机在真基站上进行注册后，才可以进行数据业务(网络数据通信)以及语音业务(例如，语音通话、短信收发等)。在注册的过程中由于基站需要对手机进行识别，确定是否为非法用户，若为非法用户，则基站将会拒绝手机注册。由此，本发明实施例通过开机搜网注册和小区重选注册流程中识别伪基站。当选择确认待注册的网络频段是GSM频段时，需要对待注册的基站是否为伪基站进行识别。
伪基站通常是通过工程手机获得手机上邻小区BCCH(Broadcast Control Channel，广播控制信道)频率和场强信息，选定信号最弱的小区进行伪装；然后根据GSM小区选择和重选算法，伪基站小区生成极大的C2值，以吸入周围的用户手机驻留(即手机接入该伪基站组建的GSM网络)。此时，伪基站可以获得用户TMSI/IMSI/IMEI等网络底层信息，最后设置任意主叫号码通过SDCCH信道发送向用户发送信息(例如，诈骗短信)。因此，伪基站不与真正的移动网络互联，当用户手机接入到伪基站后，用户无法拨通真正的用户，也无法给真正用户和网站发送信息和数据。
本实施例中，上述用户识别码为基站用于识别用户是否为非法用户的 参数，可以理解的是，在不同的协议代码下用户识别码的内容不同。具体地，该用户识别码包括IMSI(International Mobile Subscriber Identification Number，国际移动用户识别码)、IMEI(International Mobile Equipment Identity，国际移动设备标识)、TMSI(Temporary Mobile Subscriber Identity，临时识别码)和IMEISV(International Mobile Equipment Identity Software Version)中的一种。
具体地，当用户确定待注册的网络频段对应的基站后，则向该基站发送位置更新注册请求，此时将判断用户是否首次向该基站发送位置更新注册请求，若是，则以错误的用户识别码设定位置更新注册请求中预置参数形成特定的位置更新注册请求，然后将该特定的位置更新注册请求发送至基站。可以理解的是，上述错误的用户识别码用于在基站上进行非法用户识别时，识别失败。具体地，该错误的用户识别码的设置方式可以根据实际需要进行设置，例如可以修改用户识别码的位数或者在正确的用户识别码上增加一个固定值(如加1)等，其具体地实现方式在此不做进一步的限定。若待注册的基站为非首次注册，则按照正常的注册流程进行位置更新注册，正常的位置更新注册流程在此不作进一步地说明。
步骤S150，判断在第一预设时间段内是否接收到待注册的基站根据位置更新注册请求发送的第一拒绝注册信息；若是，则执行步骤S160，否则执行步骤S170；
步骤S160，根据正确的用户卡识别码向待注册基站重新注册；
步骤S170，重新搜网，并根据搜索到的网络重新确定待注册的网络频段，以重启注册流程。
本实施例中，当待注册基站接收到上述位置更新注册请求时，将会根据该位置更新注册请求中预置参数获取用户识别码。由于此时接收到的用户识别码为错误的识别码，因此待注册的基站在进行用户识别时，将认定 当前注册的手机为非法用户，此时将拒绝该手机注册，与此同时将向手机发送第一拒绝注册信息。基于上述注册原理，通过手机在根据错误的用户识别码发送位置更新注册请求后，判断在第一预设时间段内是否接收到基站返回的第一拒绝注册信息的结果即可实现对基站的真伪鉴别。具体地，若在第一预设时间段内接收到待注册的基站根据位置更新注册请求发送的第一拒绝注册信息，则确定上述待注册的基站为真基站；若在第一预设时间段内没有接收到待注册的基站根据位置更新注册请求发送的第一拒绝注册信息，则确定上述待注册的基站为伪基站。可以理解的是，上述第一预设时间段的时间长度可以根据实际需要进行设置，在此不做进一步地限定。
当通过识别认定为真基站后，可以按照正常的注册流程在该待注册的基站上进行注册，即在本实施例中，可以根据正确的用户卡识别码向待注册基站重新注册。
在确定待注册的基站为伪基站时，搜索网络，并将搜索到各频段的网络按照信号强度排列，以进行联网注册；在确定待注册的网络频段时，判断待注册的网络频段是否为GSM频段；当待注册的网络频段为GSM频段时，重新按照待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册执行相应的判断，并根据判断的结果重新完成注册流程。即当重新选定的待注册基站之前已经注册过，则按照正常的注册流程进行注册；若重新选定的待注册基站之前未注册过，则按照本方案注册流程进行注册，以对该基站是否为伪基站进行识别。
本发明实施例通过对GSM网络进行重选邻区测量，并将各频段的网络按照信号强度进行排列，以进行联网注册；当满足预设的重选条件时，根据各频段的网络按照信号强度确定待注册的网络频段；判断待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册；当待注册的基站为首次发送位置更新注册请求时，以错误的用户识别码设定位置更新 注册请求中预置参数，并将位置更新注册请求发送至待注册的基站；判断在第一预设时间段内是否接收到待注册的基站根据位置更新注册请求发送的第一拒绝注册信息；若是，则根据正确的用户卡识别码向待注册基站重新注册；若否，则重新搜网，并根据搜索到的网络重新确定待注册的网络频段，以重启注册流程。由于在移动终端进行X2G网络重选时对待注册的网络频段是否为伪基站频段进行了判断，从而可以防止移动终端进行X2G网络重选时连入伪基站，因此提高了移动终端在X2G网络重选过程中接入GSM网络进行通信的状态下使用的安全性。
在本发明实施例一实施方式中，参照图8，基于上述实施例，本实施例中，上述移动终端网络重选控制方法包括：
步骤S110，对GSM网络进行重选邻区测量，并将各频段的网络按照信号强度进行排列，以进行联网注册；
步骤S120，当满足预设的重选条件时，根据各频段的网络按照信号强度确定待注册的网络频段；
步骤S130，判断待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册；
步骤S140，当待注册的基站为首次发送位置更新注册请求时，以错误的用户识别码设定位置更新注册请求中预置参数，并将位置更新注册请求发送至待注册的基站；
步骤S150，判断在第一预设时间段内是否接收到待注册的基站根据位置更新注册请求发送的第一拒绝注册信息；若是，则执行步骤S200，否则执行步骤S180；
步骤S180，当在第一预设时间段内未接收到第一拒绝注册信息的情况下，判断是否接收到待注册基站根据位置更新注册请求发送的鉴权请求；若是则执行步骤S190，若否，则执行步骤S170；
步骤S190，根据第一预置算法得到错误的鉴权验证信息发送至待注册的基站；
步骤S200，判断在第二预设时间段内是否接收到待注册的基站根据错误的鉴权验证信息发送的第二拒绝注册信息；若是，则执行步骤S210，否则执行步骤S170；
步骤S210，根据正确的用户卡识别码以及第二预置算法得到正确的鉴权验证信息向待注册基站重新注册；
步骤S170，重新搜网，并根据搜索到的网络重新确定待注册的网络频段，以重启注册流程。
本实施例中，上述步骤S210替代了上述步骤S160。
如图4和图5所示，在真基站上进行注册时，若以错误的用户识别码发送位置更新注册请求后，基站将会将该位置更新注册请求发送至核心网，核心网可以在此时通过基站向手机发送第一拒绝注册信息；此外，核心网还可以在此不进行拒绝注册，在后续鉴权的过程中拒绝注册。此时核心网将通过基站向手机发送鉴权请求，该鉴权请求中携带有预置的鉴权参数。在手机接收到基站所发送的鉴权请求时，将根据该鉴权请求与第一预置算法得到错误的鉴权验证信息，然后发送至待注册基站。在真基站上可以由基站将该错误的鉴权验证信息发送给核心网进行鉴权认证，从而确定鉴权识别，并由核心网通过该真基站向手机发送第二拒绝注册信息，以拒绝真基站的注册；若假基站接收到该错误的鉴权验证信息，由于无法进行鉴权识别，通常直接接受注册，以将该注册的手机驻留在基站上。基于上述原理，可以通过判断手机是否接收到待注册的基站根据错误的鉴权验证信息发送的第二拒绝注册信息，从而确定上述待注册的基站是否为真基站。
可以理解的是，上述第二预设时间段的时间长度可以根据实际需要进行设置，在此不作进一步地限定。
具体地，上述第一拒绝注册信息和第二拒绝注册信息的内容均可以根据实际需要进行设置，在此不再详述。
应当说明的是，由于真基站在发送拒绝注册信息的时间点不同，本实施例中当手机第一次同一待注册的基站上进行注册的情况下，在进行鉴权时，仍然发送错误的鉴权验证信息，从而可以双层保证基站识别的准确性。需要在此解释的是，对于错误的鉴权验证信息的计算方式可以根据实际需要进行设置，例如可以不采用上述鉴权请求中的鉴权参数，也可以改变鉴权计算的算法表达式。其具体地改变方式在此不作进一步地限定。
在本发明实施例一实施方式中，参照图9，基于上述实施例，本实施例中，上述移动终端网络重选控制方法包括：
步骤S110，搜网模块，用于对GSM网络进行重选邻区测量，并将各频段的网络按照信号强度进行排列，以进行联网注册；
步骤S120，当满足预设的重选条件时，根据各频段的网络按照信号强度确定待注册的网络频段；
步骤S220，判断待注册的网络频段是否为伪基站频段；若是，则执行步骤S230；若否，执行步骤S130；
步骤S130，判断待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册；
步骤S140，当待注册的基站为首次发送位置更新注册请求时，以错误的用户识别码设定位置更新注册请求中预置参数，并将位置更新注册请求发送至待注册的基站；
步骤S150，判断在第一预设时间段内是否接收到待注册的基站根据位置更新注册请求发送的第一拒绝注册信息；若是，则执行步骤S160，否则执行步骤S170；
步骤S160，根据正确的用户卡识别码向待注册基站重新注册；
步骤S170，重新搜网，并根据搜索到的网络重新确定待注册的网络频段，以重启注册流程；
步骤S230，根据信号强度排列顺序重新确定待注册的网络频段。
当选择确认待注册的网络频段是GSM频段时，则可以根据预设的规则判断该待注册的网络频段是否为伪基站频段。在本实施例中，对于该预设的规则可以采用多种形式，例如采用白名单的形式，也可以采用黑名单的形式进行判断。以下将以采用黑名单的形式进行详细说明。例如可以根据之前统计的伪基站频段进行标记建表，并存储在手机当中形成预存的伪基站频段表。在进行伪基站频段判断时，上述步骤S210包括：判断在预存的伪基站频段表中是否存在待注册的网络频段；若存在，则确定待注册的网络频段为伪基站频段；若不存在，则确定待注册的网络频段为真基站频段。
可以理解的是，由于不同的用户对应有不同的需求，在本实施例中还可以设置特定的模式，以确定在移动终端在基站上注册时，是否对当前注册的基站为伪基站进行判断。具体地，本实施例提供的移动终端网络重选控制方法与上述移动终端网络重选控制方法的区别在于，在上述步骤S130之前还包括：判断是否进入伪基站识别模式；上述步骤S130具体为：当移动终端进入伪基站识别模式下，判断待注册的网络频段对应的基站是否为首次发送位置更新注册请求进行注册。
在本实施例中，可以输出一个显示界面供用户输入是否需要进行伪基站识别。当用户选择需要进入伪基站识别时，控制手机进入伪基站识别模式，此时每当切换到新的GSM网络中时，则在手机向基站进行注册时，对当前注册的基站进行识别。由于对基站进行鉴权的过程本身存在延时的问题，因此没有必要时时刻刻对注册的基站进行鉴权，毕竟伪基站出现概率小，用户在进行重要操作时进行鉴权即可。因此在本实施例中，对手机的是否进行鉴权设置了专有的模式，可以提高鉴权操作的灵活性。
具体地，以一具体完整实施例对本发明的实现过程进行详细说明。参照图10；首先由手机进行X2G重选邻区测量，将按照网络信号强度进行排序，确认待注册的基站；然后判断是否满足重选条件，若不满足重新条件，则重新根据网络信号强度排列顺序，确认待注册的基站，以重启注册流程。在满足重选条件的情况下，判断伪基站检测模式是否开启；若是，则判断待注册的基站对应的网络频段是否为伪基站频段；若否，则直接发起位置更新注册请求。在伪基站检测模式开启的情况下，当待注册的基站对应的网络频段不为伪基站频段时，通过鉴权识别待注册的基站是否为伪基站；当待注册的基站对应的网络频段为伪基站频段时，则重新根据网络信号强度排列顺序，确认待注册的基站，以重启注册流程。在识别伪基站的过程中，若确认当前注册的基站为真基站，则以正确的信息重启注册流程，发起位置更新注册请求进行注册；若确认当前注册的基站为伪基站，将该伪基站对应的频段信息储存至伪基站频段表中，并重新搜网注册。在发起位置更新请求后，将根据注册的结果执行相应的操作；若注册成功，则结束注册流程，若注册失败，则重新搜网注册。
