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地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的小区注册方法及终端进行详细地说明。
请参考图1，图1为本申请实施例提供的应用于终端的小区注册方法的流程示意图。如图1所示，本申请一方面实施例提供了一种小区注册方法，该方法应用于终端，该方法包括以下步骤：
步骤101：获取第一小区的第一频带范围。
其中，第一小区可以是终端搜索到的小区，例如，在终端接入SA的过程中，搜索到的小区即上述第一小区，又例如，在终端接入NSA的过程中，需添加辅小区，该辅小区即上述第一小区。
步骤102：在所述第一频带范围未位于所述终端支持的第二频带范围的情况下，禁止在所述第一小区注册所述终端。
需要说明的是，终端上报其支持的频段范围为其支持的频带范围所对应的一全频段的频段范围，上述第一小区为终端上报的其支持的频段范围对应的小区，在终端支持的频带范围为某一全频段的频段范围时，上述第一小区 的频带范围可与上述终端支持的频带范围一致，那么终端可以注册至上述第一小区；在终端支持的频带范围为某一全频段中的部分频段的频段范围时，若上述第一小区的频带范围也是上述终端支持的部分频段的频段范围，那么终端可以注册至上述第一小区。
可以理解，上述第一频带范围与上述第二频带范围也可位于某一全频段中不同部分频段的频段范围，具体地，对于较宽的某一全频段中，可分为第一子频段、第二子频段和第三子频段等多部分子频段，若上述第一频带范围与上述第二频带范围分别对应不同的两个子频段的频段范围，也即终端不支持上述第一小区的频带范围，但终端上报的频段能力为该全频段，因而会在上述第一小区尝试注册，通过禁止终端在上述第一小区的注册，避免终端不断在上述第一小区的循环注册，从而减少终端的功耗。
例如，对于较宽的N28频段中，可分为N28A和N28B两部分频段，若上述第一频带范围与上述第二频带范围分别对应N28A频段的频段范围和N28B频段的频段范围，也即终端不支持上述第一小区的频带范围，这样，终端在N28频段搜索到上述第一小区后，可获取上述第一小区的频带范围为N28B频段的频段范围，可确定N28B频段的频段范围为终端不支持的频带范围，并禁止在上述第一小区发起注册。
其中，上述第一频带范围可包括下行频带范围和上行频带范围，可判断下行频带范围和上行频带范围是否位于上述第二频带范围，例如，在时分双工(Time Division Duplexing，TDD)中下行频带范围和上行频带范围一致，因而可判断下行频带范围和上行频带范围中的任意一项是否位于上述第二频带范围即可；在频分双工(Frequency Division Duplexing，FDD)中，可分别判断下行频带范围和上行频带范围是否位于上述第二频带范围。若下行频带范围和上行频带范围中的至少一项未位于上述第二频带范围，可禁止在上述第一小区注册上述终端，若下行频带范围和上行频带范围均位于上述第二频带范围，可在上述第一小区注册上述终端，减少因循环注册尝试导致的功耗，并减少终端掉网的时间，从而提升终端驻网体验和终端的续航体验。
本申请实施例中，通过比较所述第一小区的第一频带范围和所述终端支持的第二频带范围，在所述第一频带范围未位于所述终端支持的第二频带范围的情况下，禁止在所述第一小区注册所述终端，可以避免终端在其不支持的频带范围的第一小区进行循环注册尝试，减少终端的功耗。
可选地，步骤101中所述获取第一小区的第一频带范围，包括：
获取网络设备发送的第一消息，所述第一消息包括所述第一小区的频带参数；
基于所述频带参数，确定所述第一频带范围。
具体地，在终端接入SA的过程中，上述第一消息可表示系统消息，或系统消息中的系统信息块1(System Information Block1，SIB1)；在终端接入NSA的过程中，上述第一消息可表示用于添加辅小区组(Secondary Cell Group，SCG)的无线资源控制(Radio Resource Control，RRC)重配置消息，通过获取上述第一消息中的第一小区的频带参数，例如，小区频点、载波带宽(carrier Bandwidth，BW)和子载波间隔(subcarrier spacing，SCS)，确定第一小区的频带范围。
可选地，所述第一消息还包括用于指示目标频段范围的频段指示参数；
所述基于所述频带参数，确定所述第一频带范围，包括：
获取预设的参照频段范围；
在所述频段指示参数与所述参照频段范围匹配的情况下，基于所述频带参数，确定所述第一频带范围，所述第一频带范围位于所述目标频段范围内。
可以理解，上述目标频段范围为与上述第一小区对应的频段范围，也即上述第一频带范围位于上述目标频段范围内，上述第一频带范围可以是上述目标频段范围的部分频段范围或全部频段范围。
可选地，上述频段指示参数可以是频段号，例如，703-748MHz(上行)/758-803MHz(下行)的频段范围可使用频段号N28表示，3300-3800MHz的频段范围可使用频段号N78表示等。
其中，可通过上述预设的参照频段范围预先设置需要进行终端支持的频 带范围与小区的频带范围是否匹配的判断对应的频段范围，也即与上述预设的参照频段范围匹配的频段范围才需进行上述判断，并确定是否禁止终端在相应小区的注册。上述预设的参照频段范围可设置为存在多个子频段的全频段，对于不存在多个子频段的全频段则无需进行上述判断。例如，可将存在N28A频段和N28B频段两个子频段的N28频段作为上述预设的参照频段范围，这样，若上述终端进行注册的小区的频段范围未位于N28频段的频段范围，则可直接进行注册尝试，若上述终端进行注册的小区的频段范围位于N28频段的频段范围，则可通过获取上述第一频带范围，并与终端支持的第二频带范围比较，以确定是否需要禁止在第一小区的注册。
并且，上述频段指示参数用于指示目标频段范围，那么，判断上述频段指示参数与上述参照频段范围是否匹配，也即判断上述频段指示参数对应的目标频段范围与上述参照频段范围是否匹配，具体地，上述参照频段范围可设置为一个或多个频段范围，上述频段指示参数与上述参照频段范围匹配，可包括上述目标频段范围与上述参照频段范围一致，或上述参照频段范围包括上述目标频段范围。
该实施方式中，在所述频段指示参数与所述参照频段范围匹配的情况下，基于所述频带参数，确定所述第一频带范围，也即可以针对匹配所述参照频段范围的频段范围，进行是否禁止在所述第一小区注册所述终端的判断，从而可对与所述预设的参照频段范围匹配的频段范围进行针对性检测，进一步减少终端功耗。
可选地，所述基于所述频带参数，确定所述第一频带范围，包括：
基于所述频带参数，计算所述第一小区的上边界频率和下边界频率；
基于所述上边界频率和所述下边界频率，确定所述第一频带范围；
在所述第一频带范围未位于所述终端支持的第二频带范围的情况下，禁止在所述第一小区注册所述终端，包括：
在所述上边界频率和所述下边界频率中的至少一项未位于所述第二频带范围的情况下，禁止在所述第一小区注册所述终端。
上述频带参数可包括用于计算上述第一频带范围的参数，例如，小区频点(absoluteFrequencyPointA)、BW和SCS，具体地，可基于上述频带参数计算第一小区的中心频率，进而计算得到第一小区的上边界频率和下边界频率，从而确定第一小区的第一频带范围。
具体地，以下行频率信息中的absoluteFrequencyPointA、BW和SCS进行计算为例，上述第一小区的中心频率、上边界频率和下边界频率的计算过程如下：
确定第一小区的发射频率：FREF＝FREF-Offs+ΔFGlobal(NREF–NREF-Offs)；
其中，NREF＝absoluteFrequencyPointA，FREF-Offs表示发射频率的偏移，ΔFGlobal表示全局的频点栅格，NREF表示小区频点号，NREF-Offs表示小区频点的偏移，并且，FREF-Offs、ΔFGlobal和NREF-Offs可基于NREF查找表1确定；
表1
若网络配置载波偏移(offsetToCarrier)不为0：
则，中心频率＝FREF+[(offsetToCarrier+BW)×12Subcarrier×BW×SCS×0.5](其中，offsetToCarrier的值为网络配置的值)；
若网络未配置offsetToCarrier，或网络配置offsetToCarrier为0:
则，中心频率＝FREF+(BW×12Subcarrier×BW×SCS×0.5)；
上边界频率＝中心频率+(12Subcarrier×BW×SCS×0.5)；
下边界频率＝中心频率-(12Subcarrier×BW×SCS×0.5)；
若上述第一小区的上边界频率和下边界频率均位于第二频带范围，则表示上述第一小区的第一频带范围位于终端支持的第二频带范围内，可以进行 注册；若上述第一小区的上边界频率未位于第二频带范围，或下边界频率未位于第二频带范围，或上边界频率和下边界频率均未位于第二频带范围，可确定上述第一小区的第一频带范围未位于上述第二频带范围，即使循环注册多次也无法成功注册，则可禁止在第一小区注册上述终端。
可选地，在步骤102中所述禁止在所述第一小区注册所述终端之后，所述方法还包括：
获取历史信息和所述第一小区的第一小区参数，所述历史信息包括多组小区参数；
若所述多组小区参数不包括所述第一小区参数，添加所述第一小区参数至所述历史信息。
其中，上述历史信息可用于记录上述终端无法注册成功的小区，也即每组小区参数对应一个小区，具体地，可通过物理小区标识、小区频点号、子载波间隔和载波带宽标识上述无法注册成功的小区。在确认上述第一小区的第一频带范围未位于终端支持的第二频带范围后，可通过上述历史信息记录上述第一小区，这样，若再次搜索到第一小区，可直接通过上述历史信息确认上述第一小区，并停止在上述第一小区注册上述终端。
可选地，每组小区参数包括如下至少一项：
物理小区标识；
小区频点号、子载波间隔和载波带宽。
可以理解，小区的频带范围可通过小区频点号、子载波间隔和载波带宽确定，因而小区频点号、子载波间隔和载波带宽都匹配的小区可禁止进行注册，或者通过物理小区标识(physical cell identity，PCI)标识需禁止进行注册的小区。
需要说明的是，若上述多组小区参数包括第一小区参数，则表示上述终端已经在第一小区进行注册尝试，并确定上述第一小区为禁止注册的小区。
该实施方式中，终端可通过所述历史信息中的多组小区参数，标识终端需禁止注册的小区，从而在确定需要禁止注册所述终端的小区后，可通过所述每组小区参数确定对应的小区，而无需再次获取小区的频带范围，并比较 小区的频带范围与所述终端支持的第二频带范围来确定是否停止在对应小区注册所述终端，减少所述终端的计算量，并提高效率。
可选地，在步骤102中所述禁止在所述第一小区注册所述终端之后，所述方法还包括：
获取第二小区的第二小区参数；
在所述多组小区参数未包括第二小区参数的情况下，获取所述第二小区的第三频带范围；
在所述第三频带范围位于所述第二频带范围的情况下，注册至所述第二小区。
其中，上述第二小区可通过在其他频段范围进行搜索确定的小区，并且可以通过获取上述第二小区的第三频带范围，以及比较上述第三频带范围与终端支持的第二频带范围，确定是否可在上述第二小区进行注册。
该实施方式中，在禁止在所述第一小区注册所述终端之后，可搜索并确定满足注册条件的第二小区，在第二小区的第三频带范围位于终端支持的第二频带范围的情况下，注册至所述第二小区，从而避免终端在不支持的频段进行循环注册，并实现在其他频段的注册。
以下对本申请提供的方法进行如下举例说明。
图2所示为终端在NSA注册的流程示意图，如图2所示，本申请实施例针对4G基站和5G基站的双连接(E-UTRA-NR Dual Connectivity，ENDC)实现的详细过程如下：
步骤201、终端在长期演进(Long Term Evolution，LTE)小区A驻留，进入步骤202；
步骤202、终端如果已经开启ENDC能力，检查终端是否在ENDC锚点小区，当同时满足“UE支持ENDC”和“在ENDC锚点小区”时进入步骤203，否则结束流程；
步骤203、检测当前网络下发添加SCG的RRC重配置消息后，根据获取RRC重配置消息中的以下参数：frequencyInfoDL中的 absoluteFrequencyPointA、BW和SCS；frequencyInfoUL中的absoluteFrequencyPointA、BW和SCS；
软件可以针对特定的频段，开启“频段范围检测”，如果终端软件配置开启了“频段范围检测”，则通过NR频带指示(FreqBandIndicatorNR)可以确定是否需要启动步骤204进行带宽是否超出限制的检测；
步骤204、查询表1，并根据以下公式计算当前小区的中心频率、上边界频率和下边界频率，如果上下边界都在硬件能力范围之内，表示当前小区允许注册；否则不允许注册；
具体地，计算过程如下：
计算小区的发射频率FREF＝FREF-Offs+ΔFGlobal(NREF–NREF-Offs)；
根据以上公式，使用NREF＝absoluteFrequencyPointA，查找表1以确定FREF-Offs、ΔFGlobal和NREF-Offs，从而计算FREF；
其中，NREF＝absoluteFrequencyPointA，FREF-Offs表示发射频率的偏移，ΔFGlobal表示全局的频点栅格，NREF表示小区频点号，NREF-Offs表示小区频点的偏移；
若网络配置offsetToCarrier不为0：
则，中心频率＝FREF+[(offsetToCarrier+BW)×12Subcarrier×BW×SCS×0.5]；(其中，offsetToCarrier的值为网络配置的值)
若网络未配置offsetToCarrier，或网络配置offsetToCarrier为0:
则，中心频率＝FREF+(BW×12Subcarrier×BW×SCS×0.5)；
上边界频率＝中心频率+(12Subcarrier×BW×SCS×0.5)；
下边界频率＝中心频率-(12Subcarrier×BW×SCS×0.5)；
步骤205、终端本地创建一个数据库1(Partial_Band_Disable_List1)，如果当前小区的信息与数据库中的其中一个数据匹配时，则执行到步骤206；否则执行步骤206和步骤207。
步骤206、禁用当前NR辅小区，打印RRC重配置出现错误，并上报RRC重配置失败给网络。继续测量其他满足条件(网络有添加测量配置)的 NR辅小区；
步骤207、将当前NR辅小区的信息：频点号(NR-ARFCN)(等于RRC重配置消息中的absoluteFrequencySSB)、PCI、SCS、BW添加到数据库1中。
其中，数据库1如表2所示：
表2
本申请实施例中，当不支持全频段的终端在注册全频段的ENDC网络时，可避免频繁的SCG添加失败，从而减少因为SCG导致的功耗增加，提升终端的续航体验。
图3所示为终端在SA注册的流程示意图，如图3所示，本申请实施例针对SA网络实现的详细过程如下：
步骤301、终端在SA小区A驻留，进入步骤302；
步骤302、终端如果已经开启5G选项(Option)2(SA独立组网)能力时进入步骤303，否则结束流程；
步骤303、小区搜索过程中，如果搜索到NR公共陆地移动网(Public Land Mobile Network，PLMN)，表示此时已经获取到系统消息的主信息块(master information block，MIB)和SIB1，根据获取SIB1中的以下参数：
frequencyInfoDL中的absoluteFrequencyPointA、BW和SCS；
frequencyInfoUL中的absoluteFrequencyPointA、BW和SCS；
软件可以针对特定的频段，开启“频段范围检测”，如果终端软件配置开启了“频段范围检测”，则通过FreqBandIndicatorNR可以确定是否需要启动步骤304进行带宽是否超出限制的检测；
步骤304、查询表1，并根据以下公式计算当前小区的中心频率、上边界频率和下边界频率，如果上下边界都在硬件能力范围之内，表示当前小区允许注册；否则不允许注册；
具体地，计算过程如下：
计算小区的发射频率FREF＝FREF-Offs+ΔFGlobal(NREF–NREF-Offs)；
根据以上公式，使用NREF＝absoluteFrequencyPointA，查找表1以确定FREF-Offs、ΔFGlobal和NREF-Offs，从而计算FREF；
其中，NREF＝absoluteFrequencyPointA，FREF-Offs表示发射频率的偏移，ΔFGlobal表示全局的频点栅格，NREF表示小区频点号，NREF-Offs表示小区频点的偏移；
若网络配置offsetToCarrier不为0：
则，中心频率＝FREF+[(offsetToCarrier+BW)×12Subcarrier×BW×SCS×0.5]；(其中，offsetToCarrier的值为网络配置的值)
若网络未配置offsetToCarrier，或网络配置offsetToCarrier为0:
则，中心频率＝FREF+(BW×12Subcarrier×BW×SCS×0.5)；
上边界频率＝中心频率+(12Subcarrier×BW×SCS×0.5)；
下边界频率＝中心频率-(12Subcarrier×BW×SCS×0.5)；
步骤305、终端本地创建一个数据库2(Partial_Band_Disable_List2)，如果当前小区的信息与数据库中的其中一个数据匹配时，则执行到步骤306；否则执行步骤306和步骤307。
步骤306、禁用当前小区，不发起小区的随机接入流程，继续搜索其他小区；
步骤307、将当前小区的信息：NR-ARFCN、PCI、SCS、BW添加到数据库2中。
其中，数据库2可参照上述实施例中的数据库1。
本申请实施例中，当不支持全频段的终端在注册全频段的SA网络时，可以避免频繁的注册SA失败，从而减少因为注册SA导致的功耗增加，也减 少了终端掉网的时间，从而提升终端驻网体验和终端的续航体验。
