示例性的，当目标第一收发天线组为第一收发天线组(A1，A6，A3，A7)时，其可对应获取各支天线的标识信息001，001，002，002。进一步的，处理器22可被配置为根据标识信息001筛选出用于更新目标收发天线组的多组第二收发天线组(A4或A8，A6，A1，A3或A7)，根据标识信息002筛选出用于更新目标第一收发天线组的多组第二收发天线组(A1或A6，A3，A7，A2或A5)。其中，筛选出的第二收发天线组内的两支天线必须具有标识信息为001的辐射面1，其该辐射面1为第二收发天线组内的第二辐射面。相应的，筛选出的第二收发天线组内的两支天线必须具有标识信息为002的辐射面2，其该辐射面2为第二收发天线组内的第二辐射面。基于射频电路242可对应测量多个第二收发天线组测量的网络信息，处理器220可基于每个第二收发天线组对应测量天线信号的网络信息以获取具有最大值的网络信息，并将具有最大值网络信息对应的第二收发天线组作为新的目标第一收发天线组，进而可以配置射频电路242控制导通新的目标第一收发天线组所在的射频通路，以使新的目标第一收发天线组收发天线信号。
本实施例中，客户前置设备10都能够更为准确的确定出目标第一收发天线组，实现动态地判断和基站通信的最佳天线发射/接收方向，“定向地”“迎合”基站的上下行来波方向去完成进行5G信号的收发，从而提升整体的信号覆盖范围，并提升吞吐量的效果，同时保证了4*4MIMO的高速率和高通信容量的优点，又提高了天线增益，增加了覆盖范围，又能避免其他接收信号不强的天线在工作时产生的能量消耗。
在其中一个实施例中，辐射面朝向相同(同一天线组内)的两支天线的极化方向不同。具体地，一支天线为+45°极化天线，另一支天线为-45°极化天线，其天线极化方向构成了正交关系，减少了组内两支天线之间的互相关性。示例性的，天线A1、A2、A3、A4均为+45°极化天线，天线A5、A6、A7、A8均为-45°极化天线。
在其中一个实施例中，当处理器22获取目标第二收发天线组时，处理器22进一步被配置为进一步为获取目标第二收发天线组中各支天线的极化方向和标识信息。根据标识信息确定目标第二收发天线组中待切换的第一天线和第二天线；将第一天线切换为与第一天线的标识信息相同，且极化方向不同的第三天线，将第二天线切换为与第二天线的标识信息相同，且极化方向不同的第四天线。示例性的，若目标第二收发天线组为第二收发天线组(A4，A6，A1，A7)，根据该标识信息004、001、001和002可以确定目标第二收发天线组中待切换的第一天线的标识信息为004，待切换的标识信息为002，进而可以确定出第一天线A4和第二天线A7。可将目标第二收发天线组的第一天线A4切换为与该第一天线A4具有相同标识信息且极化方向相反的第三天线A8，将第二天线A7切换为与该第二天线A7具有相同标识信息且极化方向相反的第四天线A3以构成第二收发天线组(A8，A6，A1，A3)。射频电路242可将目标第二收发天线组切换为处理器配置出的第二收发天线组(A8，A6，A1，A3)，并对应测量第二收发天线组(A8，A6，A1，A3)接收的天线信号的网络信息。处理器22可对应获取目标第二收发天线组(A4，A6，A1，A7)与第二收发天线组(A8，A6，A1，A3)对应的两个网络信息，并将其进行比较，将具有较大的网络信息对应的第二收发天线组作为新的目标第二收发天线组。本实施例中，可以对目标第二收发天线组进行校准与更新，可以进一步提高天线增益。
在其中一个实施例中，处理器22可被进一步配置为：根据第一收发天线组和第二收发天线组内各支天线的标识信息构建第一预设切换策略，第一预设切换策略包括第一收发天线组与第二收发天线组交替切换。具体地，第一预设切换策略可以为按照第一收发天线组→第二收发天线组→第一收发天线组→…→第二收发天线组的切换顺序实现对多个收发天线组的切换控制。其中，相邻切换的第一收发天线组与第二收发天线组中均具有两支天线具有同一标识信息。
需要说明的是，第一预设切换策略中包括多条第一收发天线组与第二收发天线组交替切换的切换路径。
处理器22被配置为获取当前处于工作状态的第一收发天线组内各支天线辐射面的标识信息。示例性的，若当前第一收发天线组为第一收发天线组(A1，A6，A3，A7)，其对应的第一预设切换策略为，第一收发天线组(A1，A6，A3，A7)→第一收发天线组(A4或A8，A6，A1，A3或A7)→第一收发天线组(A1，A6，A4，A8)或第一收发天线组(A3，A7，A2，A5)→第二收发天线组。
如图11所示，若当前第一收发天线组为第一收发天线组(A1，A6，A3，A7)，其对应的第一预设切换策略为第一收发天线组(A1，A6，A3，A7)→第二收发天线组(A4，A6，A1，A7)。
处理器22可被配置为获取基于第一收发天线组(A1，A6，A3，A7)和第二收发天线组(A4，A6，A1，A7)测量的网络信息来选择下一收发天线组的切换路径。若基于第一收发天线组(A1，A6，A3，A7)测量的网络信息大于基于第二收发天线组(A4，A6，A1，A7)测量的网络信息，则由第二收发天线组(A4，A6，A1，A7)向第一收发天线组(A3，A7，A2，A5)切换。反之，则由第二收发天线组(A4，A6，A1，A7)向第一收发天线组(A1，A6，A4，A8)切换。
处理器22进一步被配置为控制射频电路242按照第一预设切换策略来控制多个收发天线组依次处于工作状态，并对应测量各个收发天线组接收天线信号的网络信息。处理器22可应获取多个第一收发天线组和多个第二收发天线组对应测量天线信号的网络信息，并根据测量的多个网络信息配置射频电路更新目标第一收发天线组其中，在本实施例中，目标第一收发天线组可以为第一收发天线组也可以为第二收发天线组。
在本实施例中，客户前置设备可基于第一预设切换策略从第一收发天线组向第二收发天线组切换，在切换的过程中，可以从第一预设切换策略的多天切换路径中择优选取下一切换收发天线组，可以提高确定出目标第一收发天线组的效率。
在其中一个实施例中，处理器22进一步被配置为：从八支天线中配置多个第三收发天线组；其中，第三收发天线组由四支天线组成，如图12所示，可从四个天线组中各选取一支来构成第三收发天线组，且第三收发天线组的四支天线的辐射面朝向四个不同的方向。
在其中一个实施例中，处理器22进一步被配置为：根据第一收发天线组、第二收发天线组和第三收发天线组内各支天线的标识信息构建第二预设切换策略。第二预设切换策略至少包括按第一收发天线组、第二收发天线组、第三收发天线组依次切换。
处理器22进一步被配置为控制射频电路242按照第二预设切换策略来控制多个收发天线组依次处于工作状态，并对应测量各个收发天线组接收天线信号的网络信息。处理器22可基于射频电路242对应测量的第一收发天线组、第二收发天线组、第三收发天线组的网络信息确定目标第三收发天线组。目标第三收发天线组为第一收发天线组或第二收发天线组。在本实施例中，客户前置设备可基于第二预设切换策略来执行各个收发天线组间的切换，可以提高确定出目标第三收发天线组的效率。
在其中一个实施例中，处理器22可进一步被配置为：根据至少一个第三收发天线组筛选出基准接入天线组。客户前置设备开机时，并不知晓客户前置设备周边的基站以及NR小区的分布情况，为了使客户前置设备能够最大概率的接入第二网络系统，可以将任一组第三收发天线组作为基准接入天线组进行尝试接入。示例性的，基准接入天线组可以为收发天线组(A6、A8、A2、A3)、收发天线组(A6、A4、A2、A7)和收发天线组(A1、A8、A5、A3)和收发天线组(A1、A4、A5、A7)。需要说明的是，由于n41频带限制，最后一种方案(A1、A4、A5、A7)不作为基准接入天线组。
以第三收发天线组(A6、A8、A2、A3)作为基准接入收发天线组为例进行说明。处理器22可进一步被配置为控制射频电路242按照第三预设切换策略来执行由基准接入天线组切换至每一第一收 发天线组的切换操作。其中，第三预设切换策略包括基准接入天线组与第一收发天线组交替切换，且基准接入天线组作为起始收发天线组。
示例性的，当第三收发天线组(A6、A8、A2、A3)接入成功时，如图13所示，按照第三预设切换策略具体的遍历切换路径如下：第三收发天线组(A6、A8、A2、A3)→第一收发天线组(A1、A6、A4、A8)→第三收发天线组(A6、A8、A2、A3)→第一收发天线组(A2、A5、A4、A8)→第三收发天线组(A6、A8、A2、A3)→第一收发天线组(A2、A5、A3、A7)→第三收发天线组(A6、A8、A2、A3)→第一收发天线组(A3、A7、A1、A6)。
射频电路242按照第三预设切换策略控制多个收发天线组依次处于工作状态时，可以对应测量每个收发天线组接收的天线信号的网络信息，处理器22可被进一步配置为根据射频电路242测量的多个第一收发天线组对应测量的网络信息可以确定目标第一收发天线组。
在本实施例中，可以将第三收发天线组作为基准接入收发天线组来接入至5G网络系统，并且两组第一收发天线组切换时，均会通过第三收发天线组来承接，可以避免在切换的过程中出现掉网的情况，保证了接入5G网络系统的稳定性。
在其中一个实施例中，处理器22进一步被配置为：控制射频电路242按照第四预设切换策略来执行由基准接入天线遍历切换至多个第二收发天线组的切换操作。处理器22进一步被配置为控制射频电路242按照第四预设切换策略来控制多个收发天线组依次处于工作状态，并对应测量各个收发天线组接收天线信号的网络信息。处理器22可基于射频电路242测量的多个网络信息筛选出预选接入天线组。
示例性的，当以第三收发天线组(A6、A8、A2、A3)作为基准接入天线组为例进行说明。当第三收发天线组(A6、A8、A2、A3)接入成功时，如图14所示，按照第四预设切换策略具体的切换遍历路径如下：第三收发天线组(A6、A8、A2、A3)→第二收发天线组(A1、A6、A8、A3)→第三收发天线组(A6、A8、A2、A3)→第二收发天线组(A6、A8、A4、A2)→第三收发天线组(A6、A8、A2、A3)→第二收发天线组(A8、A2、A5、A3)→第三收发天线组(A6、A8、A2、A3)→第二收发天线组(A6、A2、A3、A7)。处理器22进一步被配置为基于多个第二收发天线组对应测量出多个网络信息，并将具有最大值网络信息的第二收发天线组作为预选接入天线组。
处理器22进一步被配置为根据预选接入天线组确定多个第一收发天线组；基于确定的多个第一收发天线组测量的多个网络信息确定目标第一收发天线组。具体地，当处理器22进一步被配置为获取预选接入天线组内各支天线的标识信息；根据标识信息确定多个待切换的第一收发天线组。其中，每组待切换的第一收发天线组中各支天线的标识信息与预选接入天线组中部分天线的标识信息相关联。
示例性的，当预选接入天线组为第二收发天线组(A1、A6、A8、A3)时，可以对应获取第二收发天线组(A1、A6、A8、A3)内各支天线的标识信息004、001、001、002。进而可以根据标识信息确定两个待切换的第一收发天线组(A4、A8、A1、A6)和第一收发天线组(A1、A6、A3、A7)。其中，可保持第二收发天线组中两支具有相同标识信息的天线不变，可将具有标识信息004的天线切换为也具有标识信息002的天线即可构成第一收发天线组(A1、A6、A3、A7)，或，可保持第二收发天线组中两支具有相同标识信息的天线不变，可将具有标识信息002的天线切换为也具有标识信息004的天线即可构成第一收发天线组(A4、A8、A1、A6)。射频电路242可以控制预选接入天线组切换至多个待切换的第一收发天线组，并对应测量多个第一收发天线组处于工作状态时接收天线信号的网络信息。处理器22可基于射频电路242测量的多个网络信息确定目标第一收发天线组。
当处理器22进一步被配置为基于确定的多个第一收发天线组测量的多个网络信息确定目标收发天线组时，处理器22可被配置来按照切换路径来实现切换，其中，如图15所示，切换路径为第二收发天线组(A1、A6、A8、A3)→第一收发天线组(A4、A8、A1、A6)→第二收发天线组(A1、A6、A8、A3)→第一收发天线组(A1、A6、A3、A7)。在切换的过程中，可以基于两组第一收发天线组测量的网络信息来确定目标第一收发天线组。
在其中一个实施例中，处理器22进一步被配置为根据第二收发天线组内各支天线的标识信息构建第五预设切换策略。第五预设切换策略包括基准接入天线组与第二收发天线组交替切换。具体的，处理器22进一步被配置为控制射频电路242按照第五预设切换策略来执行相应的切换操作，并在多个收 发天线组的切换过程中，可基于射频电路242获取基于当前收发天线组和上一收发天线组测量的网络信息，进而可更新第五预设切换策略，直到确定预选接入天线组。
第五预设切换策略中包括多路基准接入天线组与第二收发天线组交替切换的切换路径，其切换路径并不是遍历切换至每一第二收发天线组，而是切换至部分第二收发天线组。
示例性的，当以第三收发天线组(A6、A8、A2、A3)作为基准接入天线组为例进行说明。当第三收发天线组(A6、A8、A2、A3)接入成功时，可以基于第三收发天线组对应测量网络信息Q1，并按照第五预设切换策略切换至第二收发天线组(A4、A1、A6、A7)，基于第二收发天线组(A4、A1、A6、A7)可对应测量网络信息Q2。处理器22可被配置为获取基于当前收发天线组(第二收发天线组(A4、A1、A6、A7))测量的网络信息Q2和上一收发天线组(第三收发天线组(A6、A8、A2、A3))测量的网络信息Q1来更新第五预设切换策略。若网络信息Q2大于网络信息Q1则继续按照路径：第二收发天线组(A4、A1、A6、A7)→第三收发天线组(A6、A8、A2、A3)→第二收发天线组(A2、A4、A8、A6)进行切换，并获取基于第二收发天线组(A2、A4、A8、A6)测量的网络信息Q3，若网络信息Q3大于网络信息Q2，则将第二收发天线组(A2、A4、A8、A6)作为预选接入天线组。
需要说明的是，由于NR小区辐射的天线信号具有极强的方向性，客户前置设备10可将任一第三收发天线组作为接入网络的基准接入天线组，每次切换至第二收发天线组后，都会再切回至基准接入天线组，并由该基准接入天线组再次切换至另一个第二收发天线组，依次类推，直到遍历切换到每一第二收发天线组。在切换的过程中，客户前置设备10通过切回至基准接入天线组，不会因为信号质量过差而掉网。
在其中一个实施例中，客户前置设备10可以工作在非独立组网模式下，也可以工作在独立组网模式下。第三代合作伙伴计划(3rd Generation Partnership Project，简称3GPP)针对5G新空口(New Radio，简称NR)组网定义了两种方案，分别是独立组网(Stand alone，简称SA)和非独立组网(Non-Standalone，简称NSA)。当客户前置设备10需要进行5G通信时，客户前置设备10可以通过接入具有支持非独立组网或独立组网的能力小区，并根据不同的组网方式接入NR的空口，从而可以享受到5G服务。
当客户前置设备10工作在非独立组网模式下，处理器22进一步被配置为：基于第一网络系统接收基站发送的测量指令；测量指令至少包括基站配置的用于指示客户前置设备10测量第二网络系统支持的天线信号的时间信息；其中，第一网络系统为4G网络系统，第二网络系统为5G网络系统；根据测量指令基于间隔步进策略控制驱动机构驱动毫米波天线模块旋转。
具体地，处理器22可被配置为主动发起第一网络系统入网流程，并驻留在第一网络系统中。当成功驻留在第一网络系统中时，客户前置设备10可以通过第一网络系统接收基站发送的测量指令。测量指令至少包括基站配置的时间信息、客户前置设备10驻留第二网络系统的入网门限值等。其中，时间信息用于指示客户前置设备10测量第二网络系统的时间。示例性的，时间信息可为客户前置设备10进行第二网络系统测量的周期信息或非周期性信息。周期信息为客户前置设备10进行相邻两次测量时，第一次测量的开始时间与第二次测量的开始时间之间的间隔，或者第一次测量的结束时间与第二次测量的开始时间之间的间隔；或者第一次测量的结束时间与第二次测量的结束时间之间的间隔。
第一网络系统和第二网络系统可以对应相应的频段范围。示例性的，第一网络系统为4G网络，其对应的网络系统为LTE系统；第二网络系统为5G网络，对应的网络系统为5G的NR系统。
测量指令是由基站进行配置的，基站可以根据NR系统布网的密集程度设置不同的时间信息。示例性的，时间信息可为1秒、5秒、10秒等。例如，当基站确定客户前置设备10所在LTE小区周边的NR小区布网密集时，NR系统对客户前置设备10所在区域的覆盖情况较好时，基站可以控制客户前置设备10测量第二网络系统的时间信息较长，从而更好地降低客户前置设备10的功耗；当基站确定客户前置设备10所在LTE小区周边的NR小区布网较为稀疏时，基站可以控制客户前置设备10测量第二网络系统的时间信息较短，从而保证客户前置设备10能够及时检测到是否有第二网络系统的覆盖。
可选的，当客户前置设备10驻留的网络为第一网络系统(4G网络)，其第二网络系统可以为5G网络时，第一网络系统(LTE系统)支持NSA功能，即支持与第二网络系统(NR系统)的联合组网。
具体地，当处理器22被配置为根据测量指令控制多个第一收发天线组处于工作状态以对应测量天线信号的网络信息。客户前置设备10可以根据基站配置的测量指令，周期性的来测量天线信号的网络信息，而可避免实时的、持续性的测量天线信号的网络信息带来的提升客户前置设备10功耗的弊端。
以上实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
