下面结合附图对本申请所提出的一种小区的重选方法及装置进行详细的介绍。
图2为本申请一实施例的小区的重选方法的流程示意图，该方法执行主体为UE，如图2所示，该方法包括：
S201，确定候选小区。
实现中，用户设备(User Equipment，UE)处于空闲态和/或非激活态时，会持续的对其驻留的小区进行重选，以使得UE可以驻留在优先级更高和/或信号质量更佳的小区，进而使得UE可以获取到更高质量的服务。
本申请实施例中，将网络资源划分成了至少一个的网络切片，基于UE的需求，为其选择配置可以支持相应的网络切片的小区，从而使得UE可以获取到网络切片提供的差异化服务，在优化用户的体验度的同时，可以实现对于网络资源的合理利用。
网络切片，可以为用户提供一个完整的端到端的虚拟网络，通过对网络资源的划分，使得5G网络切片可以为用户提供差异化服务，以满足用户的多种需求。实现中，网络切片可以为小区提供资源，使得小区可以为UE提供服务。当UE处于空间状态和/或非激活状态等类似状态时，需要对其所属的小区持续的进行重选，以便可以驻留在更高优先级和/或信号质量更佳的小区，使得UE可以获取到更优质的服务。
小区可以为其覆盖范围内的UE提供服务，不同的小区覆盖的范围存在不同，因此，可以基于当前UE所处的地理位置，从可以覆盖到UE的小区中确定UE小区重选时的候选小区。
可选地，可以基于覆盖UE的小区的信号质量，也可以基于小区支持的切片，或者基于其他设定条件实现对候选小区的获取。
S202，根据候选小区支持的切片信息，确定UE的目标小区。
本申请实施例中，不同的候选小区支持的网络切片可以相同也可以不同。获取到候选小区后，可以通过读取候选小区的属性信息，获取候选小区支持的网络切片，进而确定候选小区支持的切片信息以及候选小区支持的切片的数量。
其中，网络切片的切片信息中可以包括切片的类型、切片的优先级等等相关参数。基于切片信息，可以从候选小区中确定UE的目标小区。
为了保证UE重选后驻留的小区可以为其提供更加优质的服务，可选地，可以基于候选小区的支持的切片以及UE所需的切片，进而确定UE的目标小区。
可选地，可以对每个候选小区支持的UE所需的切片的数量进行对比，获取其中支持的切片数量最多的至少一个候选小区，进而从候选小区中确定UE的目标小区。
可选地，可以获取每个候选小区支持的UE所需的切片的优先级，并进行对比，获取其中支持的切片的优先级最高的至少一个候选小区，进而从候选小区中确定UE的目标小区。
可选地，可以基于每个候选小区支持的UE所需的切片的数量以及切片的优先级，获取其中支持的切片优先级最高同时切片数量最多的至少一个候选小区，进而从候选小区中 确定UE的目标小区。
S203，根据目标小区进行小区重选。
本申请实施例中，基于目标小区可以确定UE重选后可以驻留的重选小区。
实现中，为了保证UE重选后驻留的小区的质量，可以基于目标小区实现重选小区的确定。进一步地，对确定的目标小区的信号质量参数基于设定的标准进行再一次的判定，以使得UE重选后驻留的小区可以为其提供更为优质的服务。
比如，设定当前获取的目标小区A，基于信号质量参数设定的标准为P，则获取目标小区A的信号质量参数，并将其与P进行对比，若目标小区A满足P对应的标准，则可以判定目标小区A可以为UE重选后驻留的重选小区。
本申请提出的小区的重选方法，确定候选小区，并基于候选小区支持的网络切片的切片信息获取到目标小区，进一步地，对目标小区进行筛选处理，获取到UE确定的进行重选的小区。本申请中，基于小区的信号质量参数获取候选小区，使得候选小区的信号质量优于非候选小区的其他小区，基于候选小区支持的切片信息从候选小区中确定目标小区，使得目标小区可以最大限度的实现对UE所需的切片的支持，进而使得UE的重选后驻留小区的可以为UE提供更为优质的差异化服务。
上述实施例的基础上，可结合图3进一步理解，图3为本申请另一实施例的小区的重选方法的流程示意图，该方法执行主体为UE，如图3所示，该方法包括：
S301，确定候选小区。
本申请实施例中，为了保证UE重选后驻留的小区相较于UE当前驻留的小区，可以为其提供更为优质的服务，可选地，可以通过获取小区支持的切片特定的网络配置信息，进而从覆盖UE的小区中确定候选小区的范围。可选地，还可以通过小区的信号质量参数的对比，从覆盖UE的小区中确定候选小区的范围。
作为一种可能的实现方式，UE可以从对其产生覆盖的小区中，获取小区的切片特定的网络配置信息。
在获取到切片特定的网络配置信息，则根据切片特定的网络配置信息确定候选小区。
本申请实施例中，网络配置信息中包括一个或多个配置参数，UE可以基于网络配置信息中的配置参数对小区进行对比，进而确定候选小区的范围。
其中，配置参数可以包括但不仅限于，切片特定的第一信号质量参数阈值、切片特定的小区数目N以及切片特定的信号质量偏差值中的至少一个。
需要说明的是，上述配置参数可以配置用于至少一个切片或至少一个切片组，可以理解为，可以将上述配置参数中任一配置参数配置用于一个切片或者多个切片组成的一个切 片组，也可以将上述配置参数中任意两个及两个以上的配置参数配置用于一个切片或者多个切片组成的一个切片组，在此不做限定。
可选地，基于UE获取到的切片特定的第一信号质量参数阈值，可以获取到信号质量参数大于或者等于第一信号质量参数阈值的小区，进一步地，将信号质量参数大于或者等于第一信号质量参数阈值的小区确定为候选小区。
可选地，基于UE获取到的切片特定的小区数目N，可以基于小区的信号质量参数进行排序，基于排序的结果从小区中获取N个，并确定为候选小区。
可选地，基于UE获取到的切片特定的信号质量偏差值，获取每个小区的信号质量偏差值，进而将属于偏差值范围内的小区确定为候选小区。
需要说明的是，上述切片特定的网络配置信息中的配置参数，可以基于其中一个配置参数确定候选小区，也可以基于其中多个配置参数确定候选小区，此处不做限定。
其中，切片特定的网络配置信息由广播系统消息和/或专用信令承载。
具体的，UE可以通过专用信令获取切片特定的网络配置信息，比如无线资源控制(Radio Resource Control，RRC)信令，也可以通过广播系统消息获取到切片特定的网络配置信息。
需要说明的是，当UE同时获取通过专用信令承载的切片特定的网络配置信息，以及通过广播系统消息承载的切片特定的网络配置信息时，UE采用专用信令承载的切片特定的网络配置信息，可以理解为，该场景下，专用信令承载的切片特定的网络配置信息对广播系统消息承载的切片特定的网络配置信息，产生了覆盖。
作为另一种可能的实现方式，UE从对其产生覆盖的小区中，基于小区的信号质量参数确定候选小区。实现中，UE在进行切片特定的网络配置信息的获取时，存在可能没有获取到切片特定的网络配置信息。本申请实施例中UE判断是否获取到小区的切片特定的网络配置信息，在未获取到切片特定的网络配置信息，则基于小区的信号质量参数确定候选小区。
在该场景下，为了最大限度的保障对UE提供的服务质量，可以从小区中选择信号质量参数最优的小区，并将其确定为候选小区。
进一步地，UE可以获取对其产生覆盖的小区的信号质量参数，并对获取到的信号质量参数进行排序，其中，排序中居于首位的小区，该小区在对UE产生覆盖的小区中的信号质量参数最佳，则可以将该小区确定为UE的候选小区。
可选地，UE可以从对其产生覆盖的小区中，获取符合S准则的小区，即搜索中的接收功率(Srxlev)大于0 dB且搜索中接收的信号质量(Squal)大于0 dB的小区，并基于符 合S准则小区的信号质量参数进行排序，获取其中居于首位的小区，将其确定为UE小区重选的候选小区。
S302，根据候选小区支持的切片信息，确定切片信息中的一个或多个选择参数。
获取到候选小区后，可以对获取到的候选小区进行进一步的筛选，UE可以读取候选小区支持的切片的切片信息，并基于切片信息从候选小区中进一步地确定UE的目标小区。
其中，UE获取到候选小区支持的切片信息后，可以从中获取到切片的一个或多个选择参数，其中，选择参数可以包括但不仅限于切片优先级、切片数目。
需要说明的是，UE获取到的候选小区支持的切片信息由广播系统消息和/或专用信令承载，可以理解为，UE可以从广播系统消息获取候选小区支持的切片信息，也可以从专用信令获取候选小区支持的切片信息，比如RRC信令。进一步地，当UE同时从广播系统消息获取到候选小区支持的切片信息，以及从从专用信令获取候选小区支持的切片信息时，UE基于专用信令获取到的候选小区支持的切片信息进行目标小区的筛选，可以理解为，该场景下，专用信令承载的候选小区支持的切片信息会对广播系统消息承载的候选小区支持的切片信息产生覆盖。
S303，根据切片信息中的一个或多个选择参数，从候选小区中，确定目标小区。
本申请实施例中，UE获取到候选小区支持的切片信息中的选择参数后，可以基于对切片的选择参数的进一步处理，从候选小区中确定目标小区。
比如，可以基于切片的优先级，从候选小区中确定支持优先级最高的切片的小区，进而确定目标小区；再比如，可以基于切片的数目，从候选小区中确定可以支持UE所需切片的数量最多的候选小区，进而确定目标小区，等等。
其中，基于切片信息中的选择参数从候选小区进行筛选，获取到的候选小区的数目存在不确定性，而UE进行小区重选后仅会驻留一个可以为其提供优质服务的小区，因此，需要对筛选获取到的候选小区进行进一步的处理，以获取目标小区。
进一步地，可以将从候选小区中基于切片信息中的选择参数筛选获取到的候选小区，确定为UE的候选目标小区。
可选地，基于获取到的候选目标小区的数量的不同情况，进行进一步的候选目标小区的筛选，以确定目标小区。
比如，若候选目标小区的数量为两个或两个以上时，则可以通对候选目标小区信号质量参数进行比较，获取到其中信号质量参数最佳的候选目标小区，并将其确定为目标小区。
再比如，若候选目标小区的数量为一个时，则可以将当前的候选目标小区确定为目标小区。
S304，根据目标小区进行小区重选。
步骤S304可参见上述实施例相关详细内容，此处不再赘述。
本申请提出的小区的重选方法，确定候选小区，并基于候选小区支持的网络切片的切片信息获取到目标小区，进一步地，对目标小区进行筛选处理，获取到UE确定的进行重选的小区。本申请中，基于小区的信号质量参数获取候选小区，使得候选小区的信号质量优于非候选小区的其他小区，基于候选小区支持的切片信息从候选小区中确定目标小区，使得目标小区可以最大限度的实现对UE所需的切片的支持，进而使得UE的重选后驻留小区的可以为UE提供更为优质的差异化服务。
上述实施例的基础上，图4为本申请另一实施例的小区的重选方法的流程图，该方法由UE执行，如图4所示，该方法包括：
S401，确定候选小区。
S402，根据候选小区支持的切片信息，确定切片信息中的一个或多个选择参数。
S403，根据切片信息中的一个或多个选择参数，从候选小区中，确定目标小区。
步骤S401～S403可参加上述实施例中相关详细内容，此处不再赘述。
S404，获取目标小区的信号质量参数。
实现中，可以为UE正常提供服务的小区存在设定的信号质量标准，可以理解为，小区的信号质量只有在符合或者高于该标准的场景中，小区才可以为UE提供正常的服务。
进一步地，将该信号质量标准确定为小区的第二信号质量阈值。
为了确保UE重选后的小区可以正常的为UE提供服务，本申请实施例中，UE获取到目标小区后，可以将目标小区的信号质量参数与第二信号质量阈值进行对比，并基于对比的结果判断目标小区是否可以作为UE的重选小区。
可选地，UE可以过读取获取到的目标小区的属性信息，进而获取到目标小区的信号质量参数。
S405，基于目标小区的信号质量参数以及第二信号质量阈值，确定UE的重选小区。
确定目标小区对应的信号质量参数后，基于目标小区的信号质量参数与第二信号质量阈值的对比结果，可以实现进一步地判断。
可选地，当目标小区的信号质量参数大于或者等于第二信号质量阈值，则将目标小区确定为UE的重选小区。
本申请实施例中，当目标小区的信号质量参数大于或者等于第二信号质量阈值时，可以理解为，该场景中，目标小区的信号质量达到了为UE提供正常的服务的标准，同时，基于至少一个选择参数确定的目标小区，可以最大限度的实现对于UE所需的切片的支持， 因此，可以将该目标小区确定为UE进行小区重选后驻留的重选小区。
可选地，当目标小区的信号质量参数小于第二信号质量阈值，则重新为UE选取新的目标小区。
本申请实施例中，当目标小区的信号质量参数小于第二信号质量阈值时，可以理解为，该场景中，目标小区的信号质量没有达到为UE提供正常的服务的标准，则当前确定的目标小区无法作为UE小区重选后驻留的重选小区。
进一步地，在该场景中，需要为UE重新进行目标小区的选择，以保证UE在进行小区重选后驻留的小区可以为其提供服务。
本申请提出的小区的重选方法，基于切片特定的网络配置信息或者小区的信号质量参数，实现候选小区的确定，基于候选小区支持的切片信息中的选择参数，确定了UE的目标小区，进一步地，基于目标小区的信号质量参数与第二信号质量阈值之间的对比结果，实现UE进行小区重选后驻留的重选小区的确认。本申请中，基于切片特定的网络配置信息或小区的信号质量参数进行候选小区的筛选，使得候选小区的信号质量优于非候选小区的其他小区，通过切片信息对候选小区进行进一步筛选，使得目标小区可以最大限度的实现对UE所需的切片的支持，基于第二信号质量阈值对目标小区进行进一步判断，使得UE的重选后驻留小区的可以为UE提供更为优质的差异化服务。
上述实施例中，关于候选小区的获取，作为其中一种可能实现的方式，可以基于获取到的切片特定的网络配置信息实现，可结合图5进一步理解，图5为本申请另一实施例的小区的重选方法的流程示意图，该方法由UE执行，如图5所示，该方法包括：
S501，在获取到切片特定的网络配置信息，则根据切片特定的网络配置信息确定候选小区。
本申请实施例中，切片特定的网络配置信息可以包括一个或多个配置参数，其中，配置参数可以包括但不仅限于切片特定的第一信号质量参数阈值、切片特定的小区数目N以及切片特定的信号质量偏差值中的至少一个。
进一步地，基于获取到的切片特定的网络配置信息中的配置参数，可以实现对于候选小区的确定。
可选地，配置参数可以是切片特定的第一信号质量参数阈值。
将信号质量参数大于或者等于切片特定的第一信号质量参数阈值的小区确定为候选小区。
本申请实施例中，不同小区的切片特定的第一信号质量参数阈值是分别设定的，可以理解为，同一切片的第一信号质量参数阈值基于支持同一切片的不同小区分别配置，不同 小区对应的第一信号质量参数阈值相同或不同。
其中，切片特定的第一信号质量参数阈值，可以理解为，小区可以为UE提供该切片相应的服务所需的信号质量参数的门限值，因此，从可以覆盖到UE的小区中，获取每个小区的切片特定的第一信号质量参数阈值，并将每个小区的信号质量参数与其对应的第一信号质量参数阈值进行对比，当小区的信号质量参数大于或者等于对应的第一信号质量参数阈值时，可以理解为，该小区的信号质量可以为UE提供切片对应的服务。
进一步地，将信号质量参数大于或者等于第一信号质量参数阈值的小区，确定为候选小区。
可选地，配置参数可以是切片特定的小区数目，将小区数目设定为N。
按照信号质量参数对小区进行排序，获取小区的信号质量参数的第一排序。
本申请实施例中，当配置参数为切片特定的小区数目N时，可以理解为，基于覆盖UE的小区，从中选择N个小区作为UE进行小区重选的候选小区。
为了保证获取到的候选小区的信号质量，UE可以获取对其进行覆盖的全部的小区的信号质量参数，并按照信号质量参数从大到小进行排序，并将获取到的排序结果确定为小区的信号质量参数的第一排序。
进一步地，将第一排序中排名前N个小区作为候选小区。
由第一排序可知，排名靠前的小区的信号质量参数优于排名靠后的小区的信号质量参数，因此，在确定第一排序后，可以从第一排序中位于首位的小区开始，顺序向后获取N个小区，即在第一排序中获取排名前N的N个小区，该N个小区可以确定为UE小区重选的候选小区。
可选地，配置参数可以是切片特定的信号质量偏差值。
将第一排序中居于首位的小区的信号质量参数，作为一个标准信号质量参数。
本申请实施例中，可以基于切片特定的信号质量偏差值对小区的信号质量进行判断。
其中，对覆盖UE的小区基于信号质量参数进行排序，获取其中信号质量参数最佳的小区，并将该小区的信号质量参数，确定为标准信号质量参数。
进一步地，将覆盖UE的小区的信号质量参数与标准信号质量参数做差，获取到的差值即为信号质量偏差值。
因此，可以基于上述示例中基于小区的信号质量参数进行排序获取到的第一排序，实现信号质量偏差值的获取。
进一步地，获取任一小区的信号质量参数与标准信号质量参数的差值，响应于差值小于或等于偏差值，确定候选小区。
确定第一排序中居于首位的小区的标准信号质量参数后，将覆盖UE的任一小区的信号质量参数分别与标准信号质量参数做差，进而获取到任一小区的基于标准信号质量参数的信号质量偏差值。将信号质量偏差值与切片特定的信号质量偏差值进行比较，基于比较的结果，实现候选小区的确定。
进一步地，获取信号质量偏差值小于或等于切片特定的信号质量偏差值的小区，并将其确定为UE进行小区重选的候选小区。可以理解为，信号质量偏差值小于或等于切片特定的信号质量偏差值的小区，其信号质量处于设定的偏差范围内，因此，该部分小区在全部的覆盖UE的小区中信号质量相对较佳，即可将该部分小区确定为UE进行小区重选的候选小区。
需要说明的是，可以基于上述任一配置参数实现候选小区的确定，也可以基于上述多个配置参数实现候选小区的确定，UE可以基于实际情况进行选择，此处不做限定。
需要进一步说明的是，关于上述基于配置参数进行候选小区的确定，存在可能，在覆盖UE的小区中不存在可以满足上述任一配置参数对应的条件的小区，在该场景中，为了保证UE可以在小区重选中获取可以驻留的小区，需要基于其他的方法进行候选小区的获取。
可选地，可以获取当前UE驻留的小区所在的频率，在与该频率相同的频率中，获取其他可以实现候选小区确定的频率点，将其确定为候选频率点。进一步地，获取候选频率点下的小区，并基于上述配置参数对获取到的候选频率点下的小区进行筛选，进而实现候选小区的确定。
可选地，获取到当前UE驻留的小区所在的频率后，在与该频率相同的同频中进行候选频率点的获取时，存在一定的可能，同频中不存在可以进行候选小区确定的候选频率点。该场景中，为了保证提供给UE的服务质量，可以基于相关机制，获取当前覆盖UE的小区中符合S准则的小区，并对基于信号质量参数对获取到的符合S准则的小区进行排序，筛选其中信号质量最佳的小区，将其作为UE进行小区重选的候选小区。
S502，根据候选小区支持的切片信息，确定UE的目标小区。
S503，根据目标小区进行小区重选。
步骤S502～步骤S503可参见上述相关详细内容，此处不再赘述。
本申请提出的小区的重选方法，在UE获取到切片特定的网络配置信息的场景中，基于网络配置信息中的配置参数，可以实现候选小区的确定，使得获取到的候选小区的信号质量优于非候选小区的其他小区，进而得UE的重选后驻留小区的可以为UE提供更为优质的差异化服务。
上述实施例中，关于目标小区的确定，可结合图6进一步理解，图6为本申请另一实施例的小区的重选方法的流程示意图，该方法由UE执行，如图6所示，该方法包括：
S601，确定候选小区。
S602，确定切片信息中的一个或多个选择参数。
步骤S601～步骤S602可参见上述相关详细内容，此处不再赘述。
S603，获取UE支持的第一切片和候选小区支持的第二切片。
为了实现为UE提供其所需的差异化服务，在进行目标小区的确定时，可以结合UE所需的第一切片以及候选小区支持的第二切片，进而实现目标小区的确定。
进一步地，UE可以通过切片信息，获取其中包含的第一切片的切片信息以及第二切片的切片信息，进而获取切片信息中包括的一个或多个选择参数。
可选地，切片信息由非接入层(Non-Access Stratum，NAS)确定，并提供给接入层(Access Stratum，AS)。
S604，根据第一切片和第二切片的一个或多个选择参数，从候选小区中确定候选目标小区。
本申请实施例中，一个或多个选择参数可以包括切片数量，还可以包括切片优先级。
其中，切片数量可以包括第一切片的数量，也可以包括第二切片的数量，还可以包括第一切片与第二切片之间的交集的切片数量。
基于选择参数对候选小区进行进一步地筛选，进而获取到目标小区
其中，基于一个或多个选择参数对候选小区进行筛选，获取到的筛选后的候选小区的数量存在不确定性，因此，可以将基于一个或多个选择参数从候选小区中筛选获取的候选小区，确定为候选目标小区，使得目标小区可以基于候选目标小区进一步获取。
可选地，可以基于切片优先级对候选小区进行筛选。
基于切片优先级，获取第一切片中优先级最高的第一目标切片，并将支持第一目标切片的候选小区，确定为候选目标小区。
本申请实施例中，优先级较高的切片可以为UE提供更为优质的服务，因此，为了使得获取到的候选目标小区在保证其信号质量的同时，还可以实现对于UE所需的切片的支持，可以将第一切片中的切片优先级进行排序，获取其中优先级最高的切片，将其确定为第一目标切片。
进一步地，从候选小区支持的第二切片中，获取包含第一目标切片的候选小区，该部分候选小区即为支持第一目标切片的候选小区，将该部分候选小区确定为候选目标小区。
比如，设定第一切片(slice)为slice1、slice2、slice3，其中，优先级关系为 slice1>slice2>slice3，则优先级最高的第一目标切片为slice1，当前候选小区(cell)为cell1、cell2、cell3，其中，候选小区cell1支持的切片为slice1、slice2，cell2支持的切片为slice2、slice3，cell3支持的切片为slice1。
进一步地，可以将支持第一目标切片slice1的候选小区确定为候选目标小区。即支持slice1的cell1以及cell3两个候选小区，可以被确定为候选目标小区。
其中，可以将候选小区中支持第一目标切片的小区确定为候选目标小区，还可以基于候选小区支持的UE所需的第一切片中全部的切片的优先级，从支持第一目标切片的候选小区中进行进一步筛选，实现候选目标小区的确定。
可选地，可以将UE支持的第一切片基于切片优先级进行划分，其中，最高优先级的切片为第一目标切片，则可以将第一切片中次一级优先级的切片确定为次一级目标切片，将基于次一级目标切片再次一级优先级的切片确定为次二级目标切片，以此类推。
具体地，基于第一切片中的切片的优先级划分，从候选小区中获取支持第一目标切片的部分候选小区，进一步地，从支持第一目标切片的部分候选小区中，获取支持第一目标切片且支持次一级目标切片的部分候选小区，进一步地，再从支持第一目标切片且支持次一级目标切片的部分候选小区，获取支持支持第一目标切片且支持次一级目标切片以及次二级目标切片的部分候选小区，以此类推，直至从全部的候选小区中筛选出支持综合优先级最高的切片的候选小区，并将其确定为候选目标小区。
可选地，可以基于切片数目对候选小区进行筛选。
对第一切片和第二切片做交集，获取交集中切片数目最多的第二目标切片，并将支持第二目标切片的候选小区，确定为候选目标小区。
实现中，候选小区支持的切片数量越多，则其可以提供的服务范围越广。
本申请实施例中，第一切片体现了UE需要的切片，第二切片体现了候选小区支持的切片，为了更加精准的为UE选取候选目标小区，同时，尽可能地选择可以更多的为UE提供服务的候选小区，可以将第一切片与第二切片做交集处理，获取到的交集中的切片即为候选小区支持且为UE需要的切片。
其中，通过对比每个候选小区支持的交集中的切片的数量，即可实现对于候选目标小区的筛选。
需要说明的是，候选目标小区基于上述至少一个的选择参数确定，可以理解为，候选目标小区可以仅基于切片优先级从候选小区中获取，也可以仅基于切片数量从候选小区中获取，还可以同时基于切片优先级以及切片数量从候选小区中获取，此处不做限定。
进一步地，对于同时基于切片优先级以及切片数量，从候选小区中获取UE的候选目 标小区，可以在获取切片的优先级后再基于切片数量进行候选目标小区的确定，也可以基于切片的数量比较后再基于切片的优先级实现候选目标小区的确定。
具体地，可以从候选小区A中获取支持最高优先级切片的候选小区B，将部分候选小区B支持的切片与UE所需的第一切片做交集处理，进一步地，从候选小区B中获取支持交集中的切片的候选小区C，并对候选小区C支持的交集中的切片的数量进行比较，获取其中支持的交集中的切片数量最多的候选小区D，将其确定为候选目标小区。
或者，可以将候选小区A支持的第二切片和UE所需的第一切片进行交集，从候选小区A中获取支持交集中的切片的候选小区E，并基于候选小区E支持的交集中的切片的数量进行比较，选择其中支持的交集中切片数量最多的候选小区F。进一步地，获取候选小区F支持的交集中的切片的优先级，并基于优先级确定候选目标小区。
可选地，可以从候选小区F中，获取支持第一目标切片的候选小区G，并将候选小区G确定为候选目标小区。
可选地，可以从候选小区F中，获取支持第一目标切片的候选小区G，进一步地，从候选小区G中，获取支持次一级目标切片的候选小区H，在进一步，从候选小区H中获取支持次二级目标切片的候选小区I，以此类推，直至获取可以支持综合优先级最高的切片组合的候选小区，并将其确定为候选目标小区。
可选地，可以将候选小区F中每个候选小区支持的切片的总优先级进行对比，并获取候选小区F中支持的切片的总优先级最高的候选小区J，将其确定为候选目标小区。
其中，候选小区J可以支持最高优先级的切片，也可以不支持最高优先级的切片，此处不做限定。
S605，基于候选目标小区，确定目标小区。
获取到UE的候选目标小区后，可以从候选目标小区中实现目标小区的选取。其中，基于一个或多个选择参数从候选小区中实现候选目标小区的选择后，获取到的候选目标小区的数量存在不确定性，因此，为了保证可以获取到最优的一个目标小区，需要分别对候选目标小区基于数量的不同进行不同的处理，进而使得可以在不同数量的候选目标小区的场景下，确定目标小区。
其中，确定的目标小区的数量为1。
实现中，获取到的候选目标小区的数量可以为1，也可以大于1，也可以为0。
作为一种可能出现的场景，候选目标小区数量为1，则将候选目标小区确定为目标小区。
本申请实施例中，当获取到的候选目标小区数量为1时，该场景中，获取到的候选目 标小区为目标小区的唯一候选项，且获取到的候选目标小区满足至少一个选择参数对应的条件，因此，可以将获取到的1个候选目标小区，确定为UE进行小区重选的目标小区。
作为另一种可能出现的场景，候选目标小区的数量大于1，则基于候选目标小区的信号质量参数，确定目标小区。
本申请实施例中，当获取到的候选目标小区数量大于1时，可以理解为，存在多个可以满足至少一个选择参数对应的条件的小区，进一步地，可以对数量大于1的候选目标小区进行进一步的筛选，
进一步地，可以获取候选目标小区所属的频率的优先级，并将其与UE当前驻留的小区所属的频率的优先级进行对比，基于对比的结果，可以确定目标小区。
可选地，当获取候选目标小区所属的频率的优先级与UE当前驻留的小区所属的频率的优先级，属于同频和/异频中的同一优先级时，当候选目标小区的频率与当前UE所属的小区的频率属于同频和/或异频的同一优先级，则则基于信号质量参数对候选目标小区进行排序，并获取候选目标小区的信号质量参数的第二排序，从第二排序中，选取居于首位的候选目标小区，确定为目标小区。
本申请实施例中，在候选目标小区所属的频率的优先级与UE当前驻留的小区所属的频率优先级，在同频和/或异频中属于同一优先级的场景中，可以基于候选目标小区的信号质量对其进行筛选。
进一步地，获取候选目标小区的信号质量参数，并基于信号质量参数对候选目标小区进行排序，并将获取到的排序结果确定为第二排序。从第二排序中，可以获取全部的候选目标小区中信号质量最佳的候选目标小区，可以理解为，从第二排序中，获取居于首位的候选目标小区，是位于第二排序中的首位的候选目标小区，并将其确定为该场景中，UE进行小区重选的目标下去。
可选地，当获取目小区所属的频率的优先级与UE当前驻留的小区所属的频率的优先级，属于同频和/或异频中的不同优先级时，当候选目标小区的频率与当前UE所属的小区的频率属于同频和/或异频的不同优先级，则基于信号质量参数对候选目标小区进行排序，并获取候选目标小区的信号质量参数的第二排序，从第二排序中，选取居于首位且频率优先级最高的候选目标小区，确定为目标小区。
本申请实施例中，在候选目标小区所属的频率的优先级与UE当前驻留的小区所属的频率优先级，在同频和/或异频中属于不同优先级的场景中，可以基于候选目标小区的信号质量参数以及候选目标小区所属频率的优先级对其进行筛选。
进一步地，可以获取候选目标小区的信号质量参数，并基于信号质量参数对候选目标 小区进行排序，与上述示例相同，获取到的排序结果可以确定为第二排序。基于第二排序，可以基于当前场景获取其中信号质量最优的候选目标小区，并获取信号质量最优的候选目标小区所属的频率的优先级，进而实现对目标小区的确定。
可以理解为，获取当前场景中信号质量参数最佳的候选目标小区，并将该候选目标小区所属的频率优先级与UE当前驻留的小区所属的频率的优先级进行对比，若候选目标小区对应的频率优先级高于UE当前驻留的小区对应的频率优先级，则将该候选目标小区确定为UE进行小区重选的目标小区。
比如，针对与UE当前驻留小区所属的频率与候选目标小区所属的频率属于异频，且优先级不同时，即可获取候选目标小区中信号质量参数最佳同时所属频率的优先级最高的候选目标小区，将其确定为目标小区。
再比如，针对UE当前驻留小区与候选目标小区为inter-RAT的小区，即可获取候选目标小区中信号质量参数最佳同时所属频率的优先级最高的候选目标小区，将其确定为目标小区。
作为还一种可能出现的场景，候选目标小区的数量为0，则基于小区的信号质量参数，确定目标小区。
本申请实施例中，候选小区中可能存在不满足任一选择参数对应的条件的候选目标小区，因此，对于候选目标小区的数量为0，可以通过其他的方式对目标小区进行确定。
其中，为了保证UE进行小区重选后驻留的小区可以尽可能的为UE提供优质的服务，因此，可以通过信号质量参数，为UE确定目标小区。
可选地，可以从覆盖UE的小区中进行筛选，基于现有机制以及小区的信号质量参数，获取小区的信号质量参数的第三排序，并将第三排序中居于首位的小区，确定为目标小区。
本申请实施例中，可以基于现有的机制，对覆盖UE的小区的信号质量参数进行排序，并将排序结果确定为第三排序。基于第三排序，可以在覆盖UE的小区中，选择信号质量参数最佳的小区，进一步地，可以将该小区确定为UE的目标小区。
可以理解为，将第三排序中居于首位的小区，并将该小区确定为UE的目标小区。
可选地，可以从候选小区中进行筛选，基于候选小区的信号质量参数，获取候选小区的信号质量参数的第四排序，从候选小区中，将第四排序中居于首位的候选小区，确定为目标小区。
本申请实施例中，可以从候选小区中重新为UE选择目标小区，其中，可以对候选小区基于信号质量参数进行排序，并将排序结果确定为第四排序。
进一步地，获取第四排序中信号质量参数最佳的候选小区，可以理解为，在第四排序 中居于首位的候选小区，该候选小区即可确定为UE的目标小区。
其中，为了使得UE可以在小区重选后获取可以驻留的小区，并且所驻留的小区可以为UE提供优质的服务，因此，在基于选择参数无法获取候选目标小区的场景中，需要基于信号质量参数对覆盖UE的小区或者UE的候选小区进行再一次的筛选，从中获取信号质量最佳的小区，作为UE的目标小区。
S606，根据目标小区进行小区重选。
步骤S606可参见上述相关详细内容，此处不再赘述。
本申请提出的小区的重选方法，基于切片的一个或多个选择参数，可以从候选小区中获取候选目标小区，并基于候选目标小区不同数量的场景，分别实现对于目标小区的确定，使得目标小区可以最大限度的实现对UE所需的切片的支持进而使得UE的重选后驻留小区的可以为UE提供更为优质的差异化服务。
上述实施例中，可以基于确定的目标小区确定UE进行小区重选后驻留的重选小区，可结合图7进一步理解，图7为本申请另一实施例的小区的重选方法的流程示意图，该方法由UE执行，如图7所示，该方法包括：
S701，确定候选小区。
S702，根据候选小区支持的切片信息，确定UE的目标小区。
步骤S701～步骤S702可参见上述相关详细内容，此处不再赘述。
S703，获取目标小区的信号质量参数。
实现中，基于上述相关参数确定的目标小区，由于只是在部分小区的范围内进行的筛选，存在可能确定的目标小区无法正常的为UE提供服务，因此，为了保证UE进行小区重选后驻留的小区可以为其提供优质的差异化服务，在目标小区确定后，可以基于设定条件，对目标小区进行进一步处理，以确定UE重选后可以驻留的重选小区。
进一步地，可以基于信号质量参数对目标小区进行筛选，并将设定条件确定为小区的第二信号质量阈值。
将当前获取的目标小区的信号质量参数与第二信号质量阈值进行对比，并基于对比的结果对目标小区进行判断。
可选地，目标小区的信号质量参数可以大于或者等于第二信号质量阈值。
S704，确定目标小区为UE的重选小区，其中，目标小区的信号质量参数大于或者等于第二信号质量阈值。
本申请实施例中，当获取到的目标小区的信号质量参数大于或者等于第二信号质量阈值时，可以理解为，当前获取到的目标小区的信号质量可以为UE提供优质的服务。
进一步地，基于上述方法获取到的目标小区，在覆盖UE的小区中信号较为优质，且可以支持UE所需的切片，因此，可以将当前获取到的目标小区确定为UE进行小区重选后驻留的重选小区。
可选地，目标小区的信号质量参数可以小于第二信号质量阈值。
S705，为UE重新选取新的目标小区，其中，目标小区的信号质量参数小于第二信号质量阈值。
本申请实施例中，第二信号质量阈值可以理解为，目标小区可以为UE正常提供服务的信号质量参数的门限值。若当前的目标小区的信号质量参数小于第二信号质量参数，可以理解为，当前获取的目标小区的信号质量参数无法为UE提供正常的服务。
进一步地，虽然当前获取到的目标小区是覆盖UE的小区中较佳的小区，但是并未达到可以为UE提供服务的标准，因此，不能将其作为UE进行小区重选后驻留的重选小区。
进一步地，需要为UE重新进行目标小区的选择。
基于信号质量参数为候选小区进行排序，获取第五排序。
具体的，由于当前确定的目标小区的信号质量参数小于第二质量参数阈值，且目标小区基于候选小区确定，因此，需要对候选小区中每个小区的信号质量参数进行判断，基于对全部的候选小区的信号质量参数的判定结果，使用不同的方法为UE重新选择新的目标小区。
进一步地，UE可以基于获取的候选小区的信号质量参数，对全部的候选小区进行排序，并将排序的结果确定为第五排序。
可选地，当目标小区的信号质量参数小于第二信号质量参数阈值，且目标小区的信号质量参数居于第五排序中的首位，则在设定时间内不再选择目标小区的同频的任一小区作为目标小区。
具体的，若当前获取的目标小区在第五排序中居于首位，可以理解为，当前获取的目标小区在全部的候选小区中，信号质量参数最佳，进一步地，当前获取的目标小区的信号质量参数并未达到第二信号质量参数阈值对应的标准，由此可知，当前目标小区对应的全部的候选小区的信号质量参数均小于第二信号质量参数阈值。
进一步地，为了使得UE重选后驻留的小区较当前驻留的小区更为优质，则不会将当前获取的目标小区的同频的任一小区作为目标小区。
其中，不再选择目标小区的同频的任一小区作为目标小区的判定存在设定时间，比如300秒。即在设定的时间范围内，不再选择目标小区同频的任一小区作为目标小区。
可选地，当目标小区的信号质量参数小于第二信号质量参数阈值，且目标小区的信号 质量参数居于第五排序中的非首位，则将候选小区中在第五排序中居于首位的候选小区，确定为UE的新的目标小区。
具体的，若当前获取的目标小区的信号质量参数小于第二信号质量参数阈值，且当前确定的目标小区的信号质量参数在第五排序中并非首位，则可以对第五排序中居于首位的候选小区进行进一步地判断。
由于第五排序中居于首位的候选小区的信号质量参数大于当前获取的目标小区的信号质量参数，则可以将第五排序中居于首位的候选小区的信号质量参数与第二信号质量参数阈值进行对比，并基于对比的结果为UE进行新的目标小区的选择。
进一步地，可以将第五排序居于首位的候选小区作为新的目标小区，并将新的目标小区的信号质量参数与第二信号质量参数阈值进行对比。
作为一种可能存在的结果，当目标小区的信号质量参数大于或者等于第二信号质量参数阈值，则将目标小区确定为UE的新的目标小区。
可以理解为，新的目标小区的信号质量参数大于第二信号质量参数阈值时，新的目标小区的信号质量参数达到了为UE提供正常服务的标准，因此，可以将该候选小区确定为UE新的目标小区。
其中，新的目标小区即为UE重选后驻留的重选小区。
作为另一种可能存在的结果，当目标小区的信号质量参数小于第二信号质量参数阈值，则在设定时间内不再选择目标小区的同频的任一小区作为目标小区。
可以理解为，第五排序中居于首位的新的目标小区的信号质量参数小于第二信号质量阈值，则第五排序中全部的候选小区均无法达到为UE提供正常服务的标准，因此，为了保证UE重选后驻留的小区可以为其提供更为优质的服务，在设定时间范围内，与新的目标小区的同频的任一小区均不会再作为UE进行小区重选时的候选小区。
