本申请提供一种小区搜索的方法和装置，能够使支持ENDC的终端设备优先驻留到支持ENDC的小区，从而使用4G和5G的双连接来获取数据服务。该方法包括：获取扫频结果，扫频结果中包含多个频点；确定扫频结果中支持ENDC的频点，并优先针对支持ENDC的频点进行小区搜索。

Description

小区搜索的方法和装置 技术领域
本申请涉及无线通信技术领域，更具体地，涉及一种小区搜索的方法和装置。
背景技术
根据第三代合作伙伴计划(the third generation partner project,3GPP)的规划，4G和5G双连接(eNodeB-nrNodeB dual carrier,ENDC)的组网方式将会使用4G基站和4G核心网，并以4G基站作为控制面的锚点，叠加5G基站进行用户面数据传输。支持双连接的终端设备可以同时使用LTE基站和5G基站，从而既可以充分利用LTE频段覆盖好的特点又可以利用5G频谱资源丰富的特点，提升终端设备的峰值传输速率。
但是，运营商对5G网络的部署是逐步推进的，在相当长的时间内，5G基站还达不到4G网络的覆盖率，5G独立组网(standalone,SA)的大范围部署会更慢。在5G网络部署的前期，将会优先采用非独立组网(non-standalone，NSA)布局，因此，网络中将大量并存支持ENDC和不支持ENDC的LTE小区。而终端设备采用现有的小区搜索流程，可能无法优先驻留到支持ENDC的小区来获取数据服务，用户体验差。
发明内容
本申请提供一种小区搜索的方法和装置，能够使支持ENDC的终端设备优先驻留到支持ENDC的小区，从而通过使用5G和4G双连接来获取数据服务，可以提升用户体验。
第一方面，本申请提供一种小区搜索的方法，该方法包括：获取扫频结果，扫频结果中包含多个频点；确定扫频结果中支持ENDC的频点，并优先针对支持ENDC的频点进行小区搜索。
采用本申请的技术方案，终端设备扫频得到扫频结果之后，增加对扫频结果中是否存在支持ENDC的频点的判断处理。如果扫频结果中支持ENDC频点和不支持ENDC的频点并存，终端设备会优先针对支持ENDC的频点发起小区搜索，可以提高终端设备优先驻留到支持ENDC的小区的机率，从而使支持ENDC的UE能够使用5G和4G双连接来获取数据服务，提升用户体验。
结合第一方面，在第一方面的某些实现方式中，扫频结果中包含的多个频点是按照频点能量大小排列的，优先针对支持ENDC的频点进行小区搜索，包括：对扫频结果包含的各频点的排列顺序进行调整，使得扫频结果中支持ENDC的频点位于扫频结果的前面；按照扫频结果中调整后的各频点的排列顺序依序进行小区搜索。
在一种可能的实现方式中，优先针对支持ENDC的频点进行小区搜索，可以是在获取到扫频结果之后，将扫频结果中支持ENDC的频点调整到扫频结果的最前面，后续按照调整之后的频点的排序进行小区搜索，就可以实现对支持ENDC的频点优先搜索。
结合第一方面，在第一方面的某些实现方式中，该方法还包括：成功驻留第一小区之 后，判断第一小区的第一频点是否包含在历史频点列表中；根据判断结果对第一频点和支持ENDC的标识作关联处理。
结合第一方面，在第一方面的某些实现方式中，根据判断结果对第一频点和支持ENDC的标识作关联处理，包括：当第一频点包含在历史频点列表中时，判断第一频点是否关联支持ENDC标识；当第一频点关联支持ENDC的标识时，清除第一频点和支持ENDC的标识的关联关系；当确定LTE基站成功添加NG基站之后，为第一频点和支持ENDC的标识之间建立关联关系。
当终端设备驻留到一个小区(例如，第一小区)后，首先判断第一小区的频点(以下称为第一频点)是否包含在历史频点列表中。如果第一频点已经包含在历史频点列表中，继续判断第一频点是否关联支持ENDC的标识。如果第一频点关联支持ENDC的标识，则先将该支持ENDC的标识清除，并在后续确定LTE基站成功添加NG基站之后再重新将第一频点和支持ENDC的标识进行关联。这样可以保证添加了支持ENDC的标识的第一频点一定是LTE基站成功添加了NG基站的。
需要说明的是，在本申请中，一个频点和支持ENDC的标识是否关联，也可以理解为该频点是否支持ENDC。可替换地，一个频点关联支持ENDC的标识，也即该频点支持ENDC，或者说，该频点携带支持ENDC的标识。相反地，一个频点不关联支持ENDC的标识，也即该频点不支持ENDC，或者时候，该频点不携带支持ENDC的标识。
结合第一方面，在第一方面的某些实现方式中，根据判断结果对第一频点和支持ENDC的标识作关联处理，包括：当第一频点不包含在历史频点列表中时，将第一频点添加到历史频点列表中；当确定LTE基站成功添加NG基站之后，将第一频点和支持ENDC的标识关联。
当终端设备驻留到一个小区(例如，第一小区)后，首先判断第一小区的频点(也即第一频点)是否包含在历史频点列表中。如果第一频点不包含在历史频点列表中，则将第一频点添加到历史频点列表中。后续，UE在确定LTE基站成功添加NG基站之后再重新将第一频点和支持ENDC的标识关联。这样可以保证添加了支持ENDC的标识的第一频点一定是LTE基站成功添加了NG基站的。
结合第一方面，在第一方面的某些实现方式中，扫频结果是在如下搜索阶段获得的：历史频点搜索阶段、优选频段搜索阶段或全频段搜索阶段。
在本申请实施例中，将支持ENDC的频点调整到频点扫描结果的最前面的处理，不限于是在频点搜索的哪个阶段。例如，在历史频点搜索阶段，在优选频段搜索阶段或者全频段搜索阶段都是可以的。
结合第一方面，在第一方面的某些实现方式中，确定扫频结果中支持ENDC的频点，包括：确定扫频结果中是否包含支持ENDC的历史频点，和/或运营商配置的支持ENDC的云频点；将扫频结果中包含的支持ENDC的历史频点和/或运营商配置的支持ENDC的云频点确定为所述支持ENDC的频点。
终端设备确定扫频结果中支持ENDC的频点包括确定扫频结果中是否包含和支持ENDC的标识关联的历史频点，以及扫频结果中是否包含由运营商配置的支持ENDC的云频点。如果存在，这些频点即为扫频结果中支持ENDC的频点。
结合第一方面，在第一方面的某些实现方式中，扫频结果是在优选频段搜索阶段进行 扫频得到的，在优选频段阶段进行小区搜索，包括：将运营商配置的支持ENDC的云频段调整至不支持ENDC的优选频段之前，并按照调整之后的频段的排序依次对各频段进行小区搜索。
在本申请实施例中，当运营商不仅配置了优选频段，还配置了支持ENDC的云频段的情况下，支持ENDC的云频段排在不支持ENDC的优选频段之前，不支持ENDC的优选频段排在其它频段或频点之前。
结合第一方面，在第一方面的某些实现方式中，第一小区属于第一非独立组网NSA区域，该方法还包括：在第二NSA区域首次进行扫频，得到的扫频结果中包含第一频点，所述第一频点和支持ENDC的标识关联；针对第一频点进行小区搜索，搜索到第二小区；成功驻留第二小区后，清除第一频点和支持ENDC的标识的关联关系。
当UE从一个NSA区域(第一NAS区域)跨到另一个NSA区域(第二NAS区域)之后，在第二NSA区域首次扫频时，UE会优先尝试搜索在第一NAS区域保存的支持ENDC的历史频点(例如，第一频点)。但是只要在该历史频点上成功驻留之后，UE就会将该历史频点和支持ENDC的标识的关联关系清除掉。并且，由于第二NSA区域和第一NSA区域由5G锚定的频段不一样，从而LTE基站不可能添加NG基站成功。这样可以确保UE在第二NSA区域中再次进行扫频时将不会再针对第一区域中支持ENDC的历史频点而优先发起搜索。
结合第一方面，在第一方面的某些实现方式中，该方法还包括：在第二NSA区域再次进行小区搜索，搜索到第一频点和至少一个第二频点；确定第一频点和该至少一个第二频点中不存在支持ENDC的频点；按照频点的能量大小对第一频点和该至少一个第二频点进行排序，并按照排序之后的频点顺序进行小区搜索。
当UE在第二NSA区域中再次发起扫频时，由于第一区域中支持ENDC的频点(例如，第一频点)不再和支持ENDC的标识关联，从而UE将不会再针对第一区域中支持ENDC的历史频点而优先发起小区搜索。因此，如果UE在第二NSA区域中再次进行小区搜索时，如果不存在支持ENDC的频点，UE将会按照频点的能量大小顺序发起小区搜索。
第二方面，本申请提供一种小区搜索的装置，所述装置具有实现第一方面及其任意可能的实现方式中的方法的功能。所述功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。所述硬件或软件包括一个或多个与上述功能相对应的单元。
可选地，所述装置为终端设备，或者，所述装置为芯片或集成电路。
可选地，所述装置还可以为处理器或基带装置。
第三方面，本申请提供一种终端设备，包括处理器和存储器。存储器用于存储计算机程序，处理器用于调用并运行存储器中存储的计算机程序，使得终端设备执行第一方面或第一方面任意可能的实现方式中的方法。
可选地，所述处理器为一个或多个，所述存储器为一个或多个。
可选地，终端设备还包括通信接口。所述通信接口可以为收发器或者输入输出接口。
第四方面，本申请提供一种计算机可读存储介质，计算机可读存储介质中存储有计算机指令，当计算机指令在计算机上运行时，使得计算机执行第一方面或第一方面的任意可能的实现方式中的方法。
第五方面，本申请提供一种芯片，包括处理器。处理器用于读取并执行存储器中存储的计算机程序，以执行第一方面或第一方面任意可能的实现方式中的方法。
可选地，所述芯片还包括存储器，存储器与处理器通过电路或电线与存储器连接，存储器用于存储计算机程序。
进一步可选地，所述芯片还包括通信接口。
第六方面，本申请提供还提供一种计算机程序产品，所述计算机程序产品包括计算机程序代码，当所述计算机程序代码在计算机上运行时，使得计算机执行上述第一方面及其任意一种可能的实现方式中的方法。
第七方面，本申请还提供一种无线通信系统，包括上述第三方面所述的终端设备。
采用本申请的技术方案，终端设备在发起小区搜索时，增加对扫频结果中是否包含支持ENDC的频点的。如果扫频结果中支持ENDC的频点和不支持ENDC的频点，终端设备会优先针对支持ENDC的频点进行小区搜索，可以有效提高终端设备优先驻留到支持ENDC的小区的机率，从而使支持ENDC的UE能够使用5G和4G双连接来获取数据服务，提升了用户体验。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
参见图1，图1是ENDC组网的架构图。如图1所示，当UE驻留到LTE小区并进入连接态之后，作为主节点的LTE基站会决定是否添加作为副节点的NR基站，从而使支持5G的UE能够同时使用LTE和NR双连接，提高传输速率。
应理解，5G也称为新空口(new radio,NR)。例如，本文中出现的5G网络也称为NR网络，5G基站也称为NR基站。
LTE的小区搜索(或者，也称为搜网)是由终端设备的非接入层(non-access stratum layer,NAS)触发。NAS向无线资源控制层(radio resource control layer,RRC)下发搜索类型。RRC根据接收到的搜索类型，决定下发给物理层(physical layer，PHY)的参数，并由PHY来进行小区搜索。
以下，将LTE的NAS记作LNAS，将LTE的RRC记作LRRC，将LTE的PHY记作LPHY。
参见图2，图2是LTE的小区搜索的各阶段的示意图。如图2所示，目前，LNAS触发的小区搜索类型包括历史频点搜索、优选频段搜索和全频段搜索三种类型。其中，优选频段搜索也称为pref-band搜索，全频段搜索也称为full band搜索。UE进行小区搜索的顺序是历史频点搜索阶段，在历史频点搜索之后未成功驻留的情况下进入优选频段搜索阶段。在优选频段搜索还未成功驻留的情况下进入全频段搜索阶段。如果以上三个阶段的搜索都失败了，还可以采用其它模式进行小区搜索，如果终端设备都未成功驻留，则开始新一轮的小区搜索，继续从历史频点搜索阶段开始。
参见图3，图3是LTE小区搜索的详细流程图。如图3所示，在LTE的小区搜索流程中，各阶段的搜索说明如下。
(1)历史频点搜索：优先搜索UE之前成功驻留过的频点(即，历史频点)。因为在短时间内UE的位置不会有太大变化，因此，优先搜索历史频点，认为会极大概率能够搜到UE之前成功驻留的小区。
(2)优选频段(pref-band)搜索：运营商有可能会预先给UE配置一些优选频段。运营商使用这些优选频段，相当于指示UE在当前区域中优先搜索哪些频段的LTE小区成功率会比较高。因此，在优选频段搜索阶段，UE会优先搜索运营商配置的这些优选频段的小区。
(3)全频段(full band)搜索：UE根据自身支持的所有LTE频段，依次在这些频段上进行搜索。一般情况下，full band搜索只有在前两种类型的搜索都不成功的情况下才启动。full band搜索的时间比较长。
如果以上三种类型的搜索都失败了，终端设备还可以切换为其它搜索模式进行搜索。如果经过其它模式的搜索，终端设备都未成功驻留，终端设备回到LTE的上述三种搜索类型，启动新一轮的搜索。
根据图3所示的LTE的小区搜索流程可以看出，在4G和5G网络大量并存的情况下，即使终端设备支持5G能力，也无法优先搜索支持ENDC的LTE小区。
下面介绍本申请的技术方案。
本申请的技术方案，保留LTE小区搜索流程的各个阶段，在此基础上增加针对历史频点支持ENDC的记录以及运营商配置的支持ENDC的云频点的判断。终端设备在搜网阶段优先尝试支持ENDC的LTE小区。
应理解，通运营商配置的支持ENDC的频点被称为云频点。
详细来说，本申请的技术方案主要增加了如下两部分：
1、历史频点支持ENDC的标识的维护。
具体地，维护历史频点支持ENDC的标识的总体原则如下：
(1)UE在成功驻留小区之后，才将驻留小区的频点添加到历史频点列表中。
(2)UE每次驻留成功之后，如果驻留小区的频点已经是历史频点且已经标记为支持ENDC，UE先清除该频点的支持ENDC的标识。UE在LTE基站成功添加了下一代(next generation,NG)基站之后，再在该频点上添加支持ENDC的标识。
在本申请实施例中，可替换地，UE为一个频点添加支持ENDC的标识，也即UE将该频点和支持ENDC的标识关联，或者说，UE将该频点标记为支持ENDC的频点。相反地，如果UE清除一个频点和支持ENDC的标识的关联关系，也即UE清除该频点携带的 支持ENDC的标识，或者说，UE将该频点标记为不支持ENDC的频点。
参见图4，图4是UE在驻留成功之后维护驻留小区支持ENDC的标识的示意图。如图4所示，UE在小区驻留成功之后，首先判断驻留小区的频点是否已经包含在历史频点列表中。如果驻留小区的频点已经包含在历史频点列表中，UE判断驻留小区的频点是否已经标记为支持ENDC(或者说，驻留小区的频点是否携带支持ENDC的标识)。如果驻留小区的频点已经被标记为支持ENDC，UE将驻留小区的频点支持ENDC的标识清除。之后，UE判断LTE基站是否成功添加NG基站。
UE在小区驻留成功之后，如果确定驻留小区的频点不包含在历史频点列表中，UE将驻留小区的频点添加进历史频点列表中。之后，UE判断LTE基站是否成功添加NG基站。
如果UE确定LTE基站成功添加NG基站，UE在历史频点列表中为驻留小区的频点增加支持ENDC的标识。
2、UE在小区搜索的过程中增加对支持ENDC的历史频点和支持ENDC的云信息的判断处理。
这里，支持ENDC的云信息包括支持ENDC的云频点和支持ENDC的云频段。和上文介绍的云频点的概念类似，云频段是指运营商配置的优选频段。
运营商可以配置支持ENDC的云频点，也可以配置不支持ENDC的云频点。同样地，运营商可以配置支持ENDC的云频段，也可以配置不支持ENDC的云频点。
下面结合图5，对UE在搜索过程中对支持ENDC的历史频点和支持ENDC的云频点的判断处理的原则进行说明。
参见图5所示，图5是本申请提供的小区搜索流程的示意图。
(1)在历史频点搜索阶段搜索历史频点和云频点。将扫频结果中的频点按照能量大小进行排序，并将扫频结果中支持ENDC的历史频点或者支持ENDC的云频点调整到扫频结果的最前面。UE按照调整之后的各频点的排列顺序依次针对各频点发起小区搜索。
可以理解的是，由于将扫频结果中支持ENDC的历史频点或者支持ENDC的云频点调整到了扫频结果的最前面，因此，UE将优先针对这些支持ENDC的历史频点和/或支持ENDC的云频点进行小区搜索。如果这些支持ENDC的历史频点和支持ENDC的云频点的小区搜索都失败了，再针对扫频结果中的剩余频点进行小区搜索。
(2)在优选频段搜索阶段，首先按照上述(1)中描述的历史频点搜索阶段的搜索原则进行一轮历史频点搜索。如果历史频点搜索失败再进行优选频段搜索。在搜索优选频段时，如果扫频结果中包含支持ENDC的历史频点或者支持ENDC的云频点，则按照物理层上报的频点顺序(已按照频点的能量大小进行了排序)优先针对这些支持ENDC的频点进行小区搜索。在这些支持ENDC的频点的小区搜索都失败之后，再发起对剩余频点的小区搜索。如果扫频结果中不包含支持ENDC的频点，则对扫频结果中的频点顺序发起小区搜索。
(3)在全频段搜索阶段，历史频点和云频点还是按照步骤(1)中描述的历史频点搜索阶段的搜索原则进行一轮历史频点搜索。如果历史频点搜索失败再进行全频段搜索。在搜索全频段时，如果扫频结果中包含支持ENDC的历史频点或者支持ENDC的云频点，则按照物理层上报的频点顺序(已按照频点的能量大小进行了排序)优先对这些频点进行小区搜索。否则，发起对剩余频点的小区搜索。
下面介绍在本申请提出的基于维护历史频点支持ENDC的标识以及UE在搜网各阶段的处理原则之下，UE进行小区搜索的流程。
参见图6，图6的(a)和(b)是本申请提供的小区搜索的方法的示意性流程图。其中，图6的(a)示出了历史频点搜索阶段和优选频段搜索阶段，(b)示出了全频段搜索阶段。
在图6所示的实施例中，假设运营商配置了支持ENDC的云频点。同时，优选频段是指由运营商配置的但是不支持ENDC的频段。
参见图6的(a)中所示的历史频点搜索阶段和优选频段搜索阶段。
1、历史频点搜索阶段。
(1)假设环境中存在一个LTE小区(以下记作小区1)，历史频点列表中保存了小区1的频点(以下记作f 1)且f1携带有支持ENDC的标识。或者，f1不属于历史频点列表，但是f 1属于运营商配置的支持ENDC的云频点。
(2)假设环境中还存在另一个LTE小区(记作小区2)，小区2的频点(以下记作f 2)包含在历史频点列表中，但是f 2未携带支持ENDC的标识，且f 2也不属于运营商配置的支持ENDC的频点。
(3)小区2的信号强于小区1，且小区1和小区2都属于UE可以驻留的小区。
UE的LNAS向LRRC下发搜网请求以及搜网类型指示，这里搜网类型指示具体为历史频点搜索。LRRC接收到历史频点搜索的指示之后，将当前保存的所有历史频点下发给LPHY，由LPHY对这些历史频点进行一次接收信号强度指示(received signal strength indication,RSSI)扫频。LPHY向LRRC上报扫频结果，扫频结果包括搜索到的RSSI以及对应的频点号回复给LRRC。其中，扫频结果中的频点已经按照各频点的RSSI的大小进行了排序。根据上文的假设，LPHY上报的扫描结果中包含频点f 1和f 2以及各自的RSSI。由于小区2的信号强于小区1，也即f 2的RSSI大于f 1的RSSI，因此，在LPHY上报的粗扫结果中，f 1排在f 2之后。
LRRC判断扫频结果(也称为粗扫结果)中是否包含支持ENDC的历史频点或者运营商配置的支持ENDC的云频点。如果存在，将这些支持ENDC的频点(包括历史频点和云频点)调整到扫频结果的最前面。例如，LRRC判断f 1的RSSI小于f 2的RSSI，但是由于f 1属于支持ENDC的频点，LRRC会将f 1调整到f 2的前面。换句话说，LRRC选择给LPHY优先下发f 1的小区搜索。
当然，如果有多个支持ENDC的频点，则可以按照RSSI的大小，对这些支持ENDC的频点进行排序。
LPHY优先针对支持ENDC的频点发起小区搜索。如果f 1的小区驻留成功，搜网结束。
而如果f 1的小区驻留失败，且历史频点搜索阶段的搜网失败，则进入优选频段搜索阶段。
2、优选频段搜索阶段。
如上文所述，图6的实施例中所述的优选频段是指不支持ENDC的优选频段。
(1)假设环境中存在一个LTE小区(以下记作小区3)，小区3的频点是f 3。f 3已经包含在历史频点列表中且f 3携带支持ENDC的标识。或者，频点f 3不包含在历史频点列表中，但是f 3属于运营商配置的支持ENDC的云频点。
(2)假设环境中还存在另外一个LTE小区(以下记作小区4)，小区4的频点为f 4。f 4包含在历史频点列表中但不携带支持ENDC的标识，f 4且也不属于运营商配置的支持ENDC的云频点。
(3)小区4的信号强于小区3，且小区3和小区4都属于UE可以驻留的小区。
优选频段搜索之前，UE先进行一次历史频点搜(过程参见上一阶段的说明)，当历史频点搜网再次失败则进入优选频段搜索阶段。
优选频段搜索开始之后，UE针对运营商配置的优选频段发起小区搜索。具体地，LPHY顺序发起优选频段的粗扫。LPHY将扫频结果发送给LRRC，粗扫结果包含搜索到的RSSI以及RSSI的频点。扫频结果中包含的频点已经按照各频点的RSSI的大小进行了排序。根据上文的假设，扫频结果中包含f 3和f 4以及各自对应的RSSI。由于小区4的信号强于小区3，也即，f 4的RSSI大于f 3的RSSI。因此，在扫频结果中，f 4排在f 3的前面。
LRRC判断扫频结果中是否包含支持ENDC的历史频点，或者运营商配置的支持ENDC的云频点。如果存在，将这些支持ENDC的频点排到扫频结果的最前面。例如，LRRC判断f 3属于支持ENDC的历史频点，或者f 3属于运营商配置的支持ENDC的云频点，即使f 3的RSSI小于f4的RSSI，LRRC还是会将f 3调整到f 4的前面。因此，LRRC选择向LPHY优先下发频点f 3的小区搜索。
如果f 3的小区驻留成功，则结束搜网流程。如果f 3的小区驻留失败，且优选频段阶段的搜网失败，则进入全频段搜网阶段。
参见图6的(b)中所示的全频段搜索阶段。
3、全频段搜索阶段。
(1)假设环境中存在一个LTE小区(以下记作小区5)，小区5的频点是f 5。f 5包含在历史频点列表中，且f 5携带支持ENDC的标识。或者，频点f 5不包含在历史频点列表中，但是f 5属于运营商配置的支持ENDC的云频点。
(2)假设环境中还存在另外一个LTE小区(以下记作小区6)，小区6的频点为f 6。f 6包含在历史频点列表中，但是未携带支持ENDC的标识。并且，频点f 6也不属于运营商配置的支持ENDC的云频点。
(3)小区6的信号强于小区5的信号，且小区5和小区6都属于可以驻留的小区。
在进入全频段搜索之前，先进行一次历史频点搜，当再次搜索失败，进入全频段搜网阶段。
全频段搜索开始之后，LRRC向LPHY下发UE支持的频段。LPHY顺序发起这些频段的粗扫。LPHY将扫频结果发送给LRRC，扫频结果中包含搜索到的RSSI以及RSSI的频点。其中，LPHY上报的扫频结果已经按照各频点的RSSI的大小进行了排序。按照假设，扫频结果中包含f 5和f 6以及各自的RSSI。由于小区6的信号强于小区5，也即，f 6的RSSI大于f 5的RSSI。因此，在粗扫结果中，f 6排在f 5的前面。
LRRC判断扫频结果中是否包含支持ENDC的历史频点或者支持ENDC的云频点。如果存在，LRRC将这些支持ENDC的频点调整到扫频结果的最前面。例如，LRRC判断f 5属于支持ENDC的历史频点，或者f 5属于支持ENDC的云频点。即使f 5的RSSI小于f 6的RSSI，LRRC依然会选择向f 5调整到f 6的前面，也即LRRC选择向LPHY优先下发频点f 5的小区搜索。
如果f 5的搜网成功，则结束搜网流程。如果f 5的搜网失败，且全频段搜网失败，UE还可以采用其它模式进行搜网。如果依然未成功驻留小区，UE开始新一轮的小区搜索。
以上图6是本申请提供的小区搜索的详细过程。
采用本申请的技术方案，终端设备在小区搜索的过程中，增加对历史频点是否支持ENDC以及运营商配置的云频点是否支持ENDC的判断处理。如果环境中支持ENDC的小区以及不支持ENDC的小区并存时，终端设备会优先对支持ENDC的历史频点以及支持ENDC的云频点进行小区搜索，可以有效提高终端设备优先驻留到支持ENDC的小区的机率，从而使支持ENDC的UE能够使用5G和4G双连接来获取数据服务，提升了用户体验。
在另一个实施例中，假设运营商只配置了支持ENDC的云频段，与图6中运营商配置了支持ENDC的云频点相比，小区搜索的各阶段将会有如下不同：
1、在历史频点搜索阶段。
LRRC收到LPHY上报的扫频结果(扫频结果已经按照各频点的RSSI的大小进行排序)之后，只判断扫频结果中是否包含支持ENDC的历史频点。如果有，则将这些支持ENDC的历史频点调整到扫频结果的最前面。
可选地，如果有多个支持ENDC的历史频点，则按照RSSI的大小，对这多个支持ENDC的频点进行排序。
LRRC向LPHY优先下发这些支持ENDC的历史频点的小区搜索。
2、在优选频段搜索阶段。
(1)LRRC将运营商配置的支持ENDC的云频段排到所有云频段(也即，运营商配置的优选频段)最前面，之后，LRRC顺序下发频段粗扫。
(2)LRRC接收到LPHY上报的扫频结果之后，只判断扫频结果包含的云频点中是否存在支持ENDC的历史频点。如果存在，则将这些支持ENDC的历史频点排到扫频结果的最前面。
LRRC向LPHY优先下发这些支持ENDC的历史频点的小区搜索。
3、在全频段搜索阶段：
LRRC接收到LPHY上报的扫频结果之后，只判断扫频结果包含的频点中是否存在支持ENDC的历史频点。如果存在，则将这些支持ENDC的历史频点排到扫频结果的最前面。
LRRC向LPHY优先下发这些支持ENDC的历史频点的小区搜索。
UE在每个搜索阶段的处理原则以及其它步骤与图6中的(a)和(b)相同，这里不再赘述。
此外，本申请考虑到ENDC的一个部署策略可能是：NSA场景下，移动网侧会把5G与一个固定的LTE频段(LTE band)锚定在一起，但是不会与所有LTE band锚定。但不同的NSA区域，5G锚定的LTE band不同。那么，就可能会导致一个支持ENDC的历史频点到了新的NSA区域之后，将不再支持ENDC，因此UE需要对保存的历史频点是否支持ENDC的信息进行更新。
上文介绍的历史频点支持ENDC的标识的维护原则，可以确保在跨NSA区域时，UE优先选择支持ENDC的LTE小区。
下面再结合图7说明UE从一个NSA移动到另一个NSA之后的搜网过程。
参见图7，图7是本申请提供的UE跨NSA时的搜网过程的示意图。
首先假设一个场景，在区域A中，UE的LPHY搜索到可用频点f 7，并对f 7进行小区搜索，搜索到小区7。UE的LRRC将f 7添加进历史频点列表中。后续，如果LTE基站成功添加了NG基站，LRRC为f 7添加支持ENDC的标识。
由于某种原因，例如信号中断，或者关机重启等，UE重新发起搜网的情况下，此时UE可能移动到了区域B。但是UE并不能获知NSA区域的变更。UE在区域B按照正常的搜网流程发起首次搜网。由于f 7保存在历史频点列表中，因此，UE的LRRC会向LPHY优先下发f 7的小区搜索。LPHY优先对f 7进行小区搜索，搜索到小区8。之后，UE成功驻留到小区8。
按照本文图4提供的对历史频点的支持ENDC的标识的维护原则，UE一旦成功驻留到一个频点，就将该频点支持ENDC的标识清除。
因此，UE成功驻留到小区8之后，UE的LRRC会将历史频点列表中f7支持ENDC的标识清除。
后续，如果LTE基站成功添加了NG基站，LRRC才会重新为f7添加支持ENDC的标识。但是，上文已经介绍过，由于区域B和区域A中由5G锚定的频段并不一样，因此，UE驻留到小区8之后，LTE基站不可能成功添加NG基站。因此，在区域B中，f 7也就不可能会被重新标记为支持ENDC。
当UE在区域B中再次发起搜网时，如果扫描到历史频点f 7和f 8，由于f 7没有支持ENDC的标识，因此不会再出现优先对f 7进行小区搜索的情况了。
UE通过每次在完成小区驻留之后，先清除历史频点携带的支持ENDC的标识。后续，如果LTE基站添加NG基站成功，再重新为该历史频点添加支持ENDC的标识，可以确保该历史频点支持ENDC的标识一定是本次成功添加NG基站之后标记的。
当UE从一个NSA区域(第一NAS区域)跨到另一个NSA区域(第二NAS区域)之后，虽然首次在第二NSA区域进行搜网时，依然会优先尝试搜索在第一NAS区域保存的支持ENDC的历史频点，但是只要在该历史频点上成功驻留之后，UE就会将该历史频点支持ENDC的标识清除掉。并且，由于第二NSA区域和第一NSA区域由5G锚定的频段不一样，因此可以确保LTE基站不会成功添加NG基站。因此，UE在第二NSA区域中再次发起搜网将不会再针对第一区域中支持ENDC的历史频点而优先发起搜索。
以上对本申请的小区搜索的方法进行了详细说明。
采用本申请的技术方案，终端设备在小区搜索的过程中，增加对历史频点是否支持ENDC以及运营商配置的云频点是否支持ENDC的判断处理。如果环境中支持ENDC的小区以及不支持ENDC的小区并存时，终端设备会优先对支持ENDC的历史频点以及支持ENDC的云频点进行小区搜索，可以有效提高终端设备优先驻留到支持ENDC的小区的机率，从而使支持ENDC的UE能够使用5G和4G双连接来获取数据服务，可以提升用户体验。
