可选地，在确定邻小区的小区测量结果大于预设测量结果的情况下，确定邻小区的小区测量结果满足配置条件。
可选地，在确定邻小区的小区测量结果大于服务小区的小区测量结果与第三偏移值(offset3)的情况下，确定邻小区的小区测量结果满足配置条件。
需要说明的是，终端接收到该配置信令后，即可确定该配置信令配置的至少一个候选小区，则终端可以对配置信令指示的至少一个候选小区进行波束测量，根据得到的波束测量结果确定是否满足评估条件，进而确实是否切换至满足评估条件的目标小区。
可选地，终端接收第一网络设备发送的配置信令后，终端不会对配置信令配置的所有候选小区进行波束测量，而是可以对配置信令配置的所有候选小区中的部分候选小区进行波束测量，进而根据部分候选小区的波束测量结果判断是否满足评估条件。
其中，终端接收第一网络设备发送的指示信令，指示信令用于指示至少一个待评估小区，至少一个待评估小区属于至少一个候选小区，且待评估小区的数量小于候选小区的数量，至少一个待评估小区为当前终端判断是否满足评估条件的小区。
在本申请实施例中，第一网络设备向终端发送指示信令，通过该指示信令即可激活至少一个候选小区中的部分小区，已激活的部分小区即为待评估小区。或者，通过该指示信令去激活至少一个候选小区中的部分小区，至少一个候选小区中除去激活的小区即为待评估小区。又或者，通过该指示信令即可选择至少一个候选小区中的部分小区，已选择的部分小区即为待评估小区。
本申请实施例通过指示信令指示至少一个待评估小区，则终端可以对至少一个待评估小区进行波束测量，得到波束测量结果，无需测量所有的候选小区，节省终端能耗。
图2所示实施例是对终端可以自行切换至小区为例进行说明。下面将对终 端采用何种方式切换至目标小区进行说明。
在一些实施例中，终端通过随机接入方式接入到切换信令指示的目标小区。对于目标小区对应的第二网络设备来说，第二网络设备响应于终端的随机接入方式，确认终端接入第二网络设备的目标小区。
其中，该随机接入方式是指终端向目标小区对应的第二网络设备发送随机接入前导码，第二网络设备接收随机接入前导码，响应于该随机接入前导码发送随机接入响应，终端接收该随机接入响应后发送RRC连接请求，第二网络设备接收该RRC连接请求后完成接入。
也就是说，本申请实施例中终端在确定目标小区满足评估条件的情况下，通过上述随机接入方式即可切换至目标小区。
在一些实施例中，用于随机接入的资源由配置信令配置。用于进行随机接入的资源是指在随机接入过程中用于传输信息的资源。
本申请实施例提供的方案中，终端通过随机接入信令切换至目标小区，打破了需要由网络设备控制终端进行切换的局限性，由终端自行确定进行小区切换，减少了所需的切换时长，提高了切换的时效性。
需要说明的是，上述实施例是以终端通过随机接入方式切换至目标小区为例进行说明。而在另一实施例中，若终端已获取TA(Timing Advance，定时提前)，则终端可以直接切换至目标小区。
在本申请实施例中，终端在已获取TA的情况下，基于已配置资源向目标小区对应的第二网络设备发送接入确认信息，切换至目标小区。对于目标小区对应的第二网络设备来说，第二网络设备接收终端发送的接入确认信息，确认终端接入目标小区。
在本申请实施例中，该TA用于指示终端的定时提前，也就是终端根据该TA可以完成上行同步，因此终端可以基于已配置资源向目标小区对应的第二网络设备发送接入确认信息，通过该接入确认信息告知第二网络设备该终端接入目标小区，进而通过目标小区进行通信。
其中，该接入确认信息用于指示终端已接入目标小区。
在一些实施例中，用于向目标小区发送接入确认信息的资源为PUSCH(Physical Uplink Shared Channel,物理层上行共享信道)资源。例如，终端通过PUSCH资源向目标小区发送MAC CE(Media Access ControlControl Element,媒体访问控制控制单元)以指示成功接入目标小区。
在另一些实施例中，用于向目标小区发送接入确认信息的资源为SR(Scheduling Request,调度请求)资源。例如，终端通过SR资源向目标小区发送SR以指示成功接入目标小区。又例如，终端通过SR资源向目标小区发送调度请求，该调度请求用于调度PUSCH，终端再基于调度的PUSCH发送configuration complete(配置完成)消息，指示确认接入该目标小区。
本申请实施例提供的方案中，终端若已获取TA，则可以通过发送接入确认信息，进而切换至目标小区，打破了需要由网络设备控制终端进行切换的局限性，由终端自行确定进行小区切换，减少了所需的切换时长，提高了切换的时效性。
需要说明的是，本申请中的第二网络设备确认终端接入后，还会向CU发送成功信息，该成功信息指示终端接入目标小区成功。
其中，本申请实施例中的CU(Central Unit,中央单元)属于gNB中的一个单元。在一些实施例中，将原有的gNB概念拆分成一个CU和多个DU(Distributed Unit,分布式单元)，CU就是一个中央单元，CU用于控制多个DU。本申请实施例不限于上述一种拆分形式，还可以有不同的拆分形式。
下面，对上述实施例进行举例说明。以第一网络设备配置的小区为源小区，第二网络设备配置的小区为目标小区，CU为gNB-CU为例，对源小区根据波束测量结果配置评估条件进行说明。参见图6，图6示出了本申请一个示例性实施例提供的切换方法的流程图，该方法包括以下内容中的至少部分内容：

步骤602：源小区根据至少一个候选小区的波束测量结果确定配置信令。
步骤603：源小区向终端发送配置信令。
步骤604：终端接收配置信令，向源小区返回配置响应。
需要说明的是，步骤604是以终端向源小区返回配置响应为例进行说明。而在另一实施例中，终端还可以向目标小区返回配置响应。
步骤605：终端在确定目标小区的波束测量结果满足评估条件的情况下，切换至目标小区。
步骤606：目标小区向gNB-CU发送成功信息，该成功信息指示终端接入目标小区成功。
需要说明的是，本申请实施例中终端所执行的步骤可以单独形成一个新的实施例，网络设备所执行的步骤也可以单独形成一个新的实施例，本申请实施例不做限定。
下面，对上述实施例进行举例说明。以第一网络设备配置的小区为源小区，第二网络设备配置的小区为目标小区，CU为gNB-CU为例，对源小区根据波束测量结果配置评估条件进行说明。参见图7，图7示出了本申请一个示例性实施例提供的切换方法的流程图，该方法包括以下内容中的至少部分内容：
步骤701：终端对至少一个邻小区进行小区测量，向源小区发送得到的小区测量结果。
步骤702：源小区向gNB-CU上报小区测量结果。
步骤703：gNB-CU根据至少一个邻小区的波束测量结果确定至少一个候选小区。
步骤704：gNB-CU向候选小区发送第一请求信息，该第一请求信息指示该候选小区为终端可以接入的小区。
步骤705：候选小区向gNB-CU返回第一响应信息。
步骤706：gNB-CU向源小区配置终端第二请求信息，第二请求信息请求包括至少一个候选小区的必要参数信息。
步骤707：源小区向终端发送配置信令。
步骤708：终端接收配置信令，向源小区返回配置响应。
步骤709：源小区向gNB-CU返回第二响应信息。
步骤710：终端在确定目标小区的波束测量结果满足评估条件的情况下，切换至目标小区。
步骤711：目标小区向gNB-CU发送成功信息，该成功信息指示终端接入目标小区成功。
需要说明的是，本申请实施例中终端所执行的步骤可以单独形成一个新的实施例，网络设备所执行的步骤也可以单独形成一个新的实施例，本申请实施例不做限定。
需要说明的是，上述实施例可以拆分为新实施例，或与其他实施例互相组合为新实施例，本申请对实施例之间的组合不做限定。

在一些实施例中，该第一网络设备对应源小区，也可以成为sourcecell(源小区)。
其中，该波束测量结果是指终端进行L1(层1)测量所得到的结果。评估条件是指供终端进行小区切换的判断条件。若终端确定候选小区的波束测量结果满足评估条件，则可以指示切换至满足评估条件的候选小区。
在本申请实施例中，该波束测量结果包括终端对至少一个候选小区测量得到的测量结果。也就是说，终端对至少一个候选小区进行测量，得到至少一个候选小区的波束测量结果，后续即可根据波束测量结果确定是否切换至目标小区。
其中，候选小区是指终端终端可以进行波束测量，并且可能作为目标小区由终端接入区。在一些实施例中，至少一个候选小区由网络设备配置。
在一些实施例中，该配置信令包括事件标识，该事件标识指示评估条件对应的事件。

例如，事件标识1指示事件1，事件标识2指示事件2，或者事件标识为其他标识，以指示其他事件，本申请实施例不作限定。
可选地，该配置信令配置的事件为L1事件，进而第一网络设备可以通过该配置信令为终端配置评估条件。
在一些实施例中，该L1时间包括以下至少一项：

在一些实施例中，该配置信令为RRC信令，或者为其他类型的信令，本申请实施例不作限定。
在一些实施例中，目标小区为终端根据至少一个候选小区的波束测量结果，确定满足评估条件的小区。
可选地，目标小区是满足评估条件的一个小区。其中，若至少一个候选小区中存在一个候选小区的波束测量结果满足评估条件，则满足该评估条件的一个候选小区作为该目标小区。
可选地，目标小区是满足评估条件的多个候选小区中确定的一个小区。在候选小区为多个的情况下，若多个候选小区中存在多个候选小区的波束测量结果满足评估条件，则从满足评估条件的多个候选小区中选择一个候选小区确定为目标小区。
本申请实施例提供的方案中，提供了一种终端根据波束测量结果确定是否进行小区切换的方案，保证终端在确定波束测量结果满足评估条件的情况下进行小区切换，打破了需要由网络设备控制终端进行切换的局限性，由终端自行确定进行小区切换，减少了所需的切换时长，提高了切换的时效性。
