对网络切片(slicing)进行介绍：
各行业对移动通信网络的性能需求与日俱增。为了提升移动通信网络的延迟、移动性、可靠性以及位置精度等方面的性能，因此需要增强无线接入网(Radio Access Network，RAN)对于具体业务的支持，其中一种方式为使用基于RAN的网络切片(切片)。网络切片能够应用于一个具体的业务，对于一个网络切片，其拥有独立的拓扑、虚拟网络资源、流量以及配置规则等。网络切片是一组带有特定无线配置和传输配置的网络功能的集合，能够实现在同一套网络设备上提供多个不同的端到端的虚拟网络。例如专为物联网(Internet of Things，IOT)业务提供的网络切片，专为车联网业务提供的网络切片，以及专为特定用户提供的网络切片等。在建立基于RAN的网络切片的过程中，服务提供方能够参与RAN的设计、部署以及操作，从而能够根据自身需求更好地支持自身提供的业务。
在R17(Release17)中，研究的重点包括增强支持网络切片的RAN，具体内容包括：使用户设备(User Equipment，UE)能够快速接入支持UE期望的网络切片的小区(cell)，包括：UE基于网络切片进行小区重选(cell reselection)。以及，基于网络切片，确定UE的随机接入信道(Random Access Channel，RACH)的配置或访问限制。
对小区重选进行介绍：
小区重选指UE在空闲模式下，通过监测当前接入的小区(也称服务小区)，以当前接入的小区的相邻小区和的信号质量，从而选择并接入一个信号最好的小区的过程。
当相邻小区的信号质量以及电平满足S(Srxlev)准则，并且满足一定重选判决准则时，UE将接入该相邻小区进行驻留。重选判决准则包括UE在执行小区选择以及重选的过程中，为了满足空闲模式下的负荷均衡，会使用基于频点优先级(小区对应的频点的优先级)的小区重选策略进行小区重选。
UE在某一小区驻留后，将持续对该小区进行测量。无线资源控制(Radio Resource Control，RRC)层，会根据参考信号接收功率(Reference Signal Received Power，RSRP)的测量结果，计算S值，并将其与同频测量启动门限(Sintrasearch)和异频/异系统测量启动门限(Snonintrasearch)进行比较，作为UE是否启动相邻小区的信号质量测量的判别条件。其中，S值即是小区选择中的S准则，公式：Srxlev＝Qrxlevmeas–(qRxLevMin+qRxLevMinOffset)–pCompensation，S准则＝测量小区的RSRP值–{最低接收电平(通常为0-128dbm)+最低接收电平偏置(通常为0)}-功率补偿(通常为0)。
对于同频小区或者异频但具有相同频点优先级的小区，UE采用R准则进行小区重选。具体的，UE按照小区的信号质量进行排序，并选择信号质量最好的小区作为候选的小区。对于高频点优先级的小区，只要小区信号质量满足一定门限，UE便会重选到频点优先级高的小区中去。对于低频点优先级的小区，只有当UE所在小区的信号质量低于一定门限时才会重选至该低频点优先级的小区中去。
对网络切片的部署进行介绍：
可以使用单网络切片选择指示信息(Single Network Slice Selection Assistance Information，S-NSSAI)来标识网络切片，S-NSSAI用于标识单一网络切片。S-NSSAI的集合称为网络切片选择指示信息(Network Slice Selection Assistance Information，NSSAI)，NSSAI中能够包括多个S-NSSAI。
UE需要使用网络切片时，需要先向网络设备发送请求。网络设备同意该请求后，会在网络切片中建立协议数据单元会话(Protocol Data Unit session，PDU session)，从而实现通过网络切片传输数据。
UE根据使用的业务，会把要请求的网络切片的S-NSSAI加入NSSAI请求(Requested NSSAI)，该Requested NSSAI会被包含在注册请求(Registration Request)消息中发送给接入和移动性管理功能实体 (Access and Mobility Management Function，AMF)。AMF根据UE签约和网络切片部署的范围确定NSSAI许可(Allowed NSSAI)，并加入注册接受(Registration Accept)消息中发给UE，还能够加入N2message中发给RAN设备(例如基站)。
UE在收到Allowed NSSAI后，需要在Allowed NSSAI对应的网络切片中建立PDU session，在PDU session建立完成后，UE能够在该网络切片中收发数据。
在网络部署时，每个网络切片的覆盖范围可能不一样，AMF在确定Allowed NSSAI时，需要保证Allowed NSSAI对应的所有的网络切片，都可以覆盖AMF分配给UE的注册区域(Registration Area)(跟踪区域列表(TrackingArea List，TA List))。AMF能够通过NG设置请求(NG Setup Request)或者RAN配置更新(RAN Configuration Update)信令从基站获得基站支持的S-NSSAI和对应的TA。
在R17中，空闲/非活跃(inactive)模式下的UE通过读取小区的系统信息中广播的基站支持的网络切片的切片信息(包括切片在各个频点的频点优先级)，能够选择一个支持UE使用的业务(业务对应的网络切片)且频点优先级高的小区。UE的非接入层(Non-Access Stratrum，NAS)会向接入层(Access Stratum，AS)提供Allowed NSSAI，从而保证UE可以选择到一个支持Allowed NSSAI对应的网络切片的小区，为后续的业务传输做准备。具体的，网络设备指示的切片信息可以包括：
每个网络切片的频点优先级的关系映射，例如网络切片、频点以及每个频点的绝对优先级的关系。可选地，上述信息能够为网络切片组中的网络切片的切片信息。
或者，每个网络切片的频率优先级映射，例如网络切片、频点以及每个频点的绝对优先级的关系。其中，上述切片信息能够是同意使用广播和专用信令提供给UE的切片信息中的一部分切片信息。
示例地，网络切片的部署涉及到情况如下：
·不同频点支持的网络切片相同或不同；
·对同一个网络切片，其对应的不同频点的频点优先级相同或不同；
·同一个频点支持的网络切片相同或不同(即同频点的不同小区支持的网络切片相同或不同)；
·对同一个网络切片，其对应的同一频点的频点优先级相同或不同(即同频点的不同小区的重选优先级相同或不同)。

(2)基于切片信息，根据第一频点是否支持目标切片确定第一频点的频点优先级。
例如，在未获取到基于切片的频点优先级的情况下，终端设备还能够根据第一频点是否支持目标切片确定第一频点的频点优先级。此时该第一频点为任一频点或支持目标切片的频点。

·针对切片信息中包括基于切片的频点优先级的情况：
在获取到基于切片的频点优先级的情况下，终端设备能够根据该包括基切片的频点优先级的切片信息，确定第一频点的频点优先级。例如根据包括切片、频点和基于切片的频点优先级之间的第三对应关系的切片信息确定频点优先级，或根据包括切片、频点、基于切片的频点优先级和小区标识之间的第四对应关系的切片信息确定频点优先级。可选地，在切片信息中包括基于切片的频点优先级的情况下，终端设备也能够确定第一频点的频点优先级为第一频点优先级。

例如，在获取到基于切片的频点优先级的情况下，终端设备能够根据第一频点是否支持目标切片确定第一频点的频点优先级。可选地，具体过程可参照针对切片信息中不包括基于切片的频点优先级的情况中，终端设备根据第一频点是否支持目标切片确定第一频点的频点优先级的实现过程，本申请在此不作赘述。此时该第一频点为任一频点或支持目标切片的频点。
(2)基于切片信息，根据第一频点支持的目标切片的频点优先级，确定第一频点的频点优先级。
根据目标切片对应的频点优先级，终端设备能够确定第一频点的频点优先级。此时该第一频点为支持目标切片的频点。
例如，在获取到基于切片的频点优先级的情况下，终端设备会根据第一频点支持的目标切片的频点优先级，确定第一频点的频点优先级。可选地，此时终端设备会将第一频点支持的目标切片的频点优先级中的最高值或最低值或任一值或平均值，确定为第一频点的频点优先级。
示例地，第一频点支持的目标切片包括切片1(频点优先级1)、切片2(频点优先级3)、切片3(频点优先级5)，终端设备根据第一频点支持的目标切片的频点优先级，确定的第一频点的频点优先级能够为5(最高值)、1(最低值)、3(任意值，切片2的频点优先级)或3(平均值)。
(3)基于切片信息，根据第一频点支持的目标切片的数量和频点优先级，确定第一频点的频点优先级。
例如，在获取到基于切片的频点优先级的情况下，终端设备会根据第一频点支持的目标切片的数量和频点优先级，确定第一频点的频点优先级。此时该第一频点为支持目标切片的频点。可选地，第一频点支持的目标切片的数量和频点优先级会共同影响终端设备确定的第一频点的频点优先级，终端设备能够根据基于第一频点支持的目标切片的数量确定的频点优先级，以及基于目标切片的频点优先级确定的频点优先级共同确定第一频点的频点优先级。
或者，根据第一频点支持的目标切片的数量，以及目标切片的频点优先级来共同确定第一频点的频点优先级。例如终端设备先根据目标切片的频点优先级确定第一频点的频点优先级，再根据第一频点支持的目标切片的数量调整确定的频点优先级。其中，第一频点支持的目标切片的数量与最终确定的第一频点的频点优先级正相关。
示例地，频点1支持的目标切片包括切片1(频点优先级1)、切片2(频点优先级3)、切片3(频点优先级5)。频点2支持的目标切片包括切片1(频点优先级1)、切片2(频点优先级3)、切片3(频点优先级5)和切片4(频点优先级3)。终端设备根据频点1支持的目标切片的频点优先级的平均值，确定频点1的频点优先级为3。终端设备根据频点2支持的目标切片的频点优先级的平均值，确定频点2的频点优先级为3。但频点2支持的目标切片的数量多于频点1，因此终端设备最终确定的频点1的频点优先级低于频点2的频点优先级。
(4)基于切片信息，在第一频点不支持目标切片的情况下，根据第一频点支持的其他切片对应的频点优先级确定第一频点的频点优先级。
例如，在获取到基于切片的频点优先级，且第一频点不支持目标切片的情况下，终端设备会根据第一 频点支持的其他切片对应的频点优先级确定第一频点的频点优先级。此时该第一频点为不支持目标切片的频点。
示例地，目标切片包括切片1、切片2和切片3，第一频点支持频点4、频点5和频点6，此时终端设备会根据频点4对应的频点优先级、频点5对应的频点优先级以及频点6对应的频点优先级来确定第一频点的频点优先级。例如将频点4对应的频点优先级、频点5对应的频点优先级和频点6对应的频点优先级中的最高值或最低值或任一值或平均值，确定为第一频点的频点优先级。

示例性的，第一测量规则可以是下述规则：
对于处在空闲或非活跃状态的UE来说，能够驻留在某个小区的前提是该小区的信号质量满足小区选择S准则。UE选择到合适的小区后会持续进行小区重选的评估，评估小区重选所要执行的测量是按照各个频点的重选优先级(基于频点优先级确定)来划分并进行的。具体内容如下所述。

·对于同频频点，当服务小区的RSRP和参考信号接收质量(Reference Signal Received Quality，RSRQ)值均高于网络配置的同频测量门限时，UE可以停止同频邻小区测量，否则是要进行测量的。
·对于同频点优先级和低频点优先级的频点，当服务小区的RSRP和RSRQ值均高于网络配置的异频测量门限时，UE可以停止同频点优先级和低频点优先级的频点的邻小区测量，否则是要进行测量的。

在第一频点支持目标切片的情况下，终端设备会有条件或无条件执行对第一频点或第一频点对应的小区的小区测量或小区搜索，或者，持续对第一频点或第一频点对应的小区进行小区测量或小区搜索。
示例性的，上述条件包括终端设备计算S值，并判断是否满足启动相邻小区的信号质量的测量。持续对第一频点或第一频点对应的小区进行小区测量或小区搜索，指终端设备无视任何条件，持续对第一频点或第一频点对应的小区进行小区测量或小区搜索。可选地，终端设备在通过上述方式进行小区测量或小区搜索的过程，是根据第一频点的基于切片信息确定的频点优先级，或第一频点优先级实现的。

(4)使用基于切片信息确定的频点优先级，基于第二测量规则进行小区测量或小区搜索。
终端设备在对第一频点或第一频点对应的小区进行小区测量或小区搜索时，还能够使用上述基于切片信息确定的第一频点的频点优先级，并按照第二测量规则对第一频点或第一频点对应的小区进行小区测量或小区搜索。

可选地，针对不同的频点优先级和重选规则，终端设备执行小区选择或小区重选的过程如下方式中的至少一种：
(1)使用第一频点优先级，基于第一重选规则进行小区选择或小区重选。
终端设备在对候选小区进行小区选择或小区重选时，能够使用候选小区对应的第一频点优先级，按照第一重选规则对候选小区进行小区选择或小区重选。可选地，使用的第一频点优先级，能够为上述基于切片信息确定的第一频点优先级，或者不为基于切片信息确定的第一频点优先级，而是直接确定的第一频点优先级。
示例性的，第一重选规则可以是下述规则：
通过测量获取多个候选小区后，UE采取高频点优先级的频点上的小区优先重选的原则。具体内容如下所述。
·对于高频点优先级的频点上的小区重选，要求其信号质量高于一定门限且持续指定时间长度，且UE驻留在原小区时间不短于1s。
·对于同频和同频点优先级的频点上的小区重选，需要满足R准则(按照RSRP排序)，新小区信号质量好于当前小区且持续指定时间长度，且UE驻留在原小区时间不短于1s。
·对于低频点优先级的频点上的小区重选，需要没有高频点优先级和同频点优先级的频点上的小区符合要求，原小区信号质量低于一定门限，低频点优先级的频点上的小区信号质量高于一定门限且持续指定时间长度，且UE驻留在原小区时间不短于1s。
在同频和同频点优先级的频点上的小区重选过程中，当出现多个候选小区都满足要求时，UE会通过RSRP排序的方式选出最好的小区作为重选的目标小区。
(2)使用第一频点优先级，基于第二重选规则进行小区选择或小区重选。
终端设备在对候选小区进行小区选择或小区重选时，还能够使用候选小区对应的第一频点优先级，并按照第二重选规则对候选小区进行小区选择或小区重选。
示例性的，第二重选规则可以是下述规则：
终端设备能够根据候选小区对应的切片信息或候选小区是否支持目标切片，来对候选小区和/或目标频点执行调整策略。之后按照第一重选规则进行小区选择或小区重选。其中，候选小区是小区重选的过程中，作为目标的小区。目标频点是候选小区对应的频点。
可选地，执行调整策略的时机为：在小区测量之前、在重选判断之前或从候选小区重选到目标小区(终端设备重选转移到的小区)之前。
终端设备能够根据网络设备指示的信息确定候选小区是否支持目标切片，例如终端设备根据所在小区的本区广播确定，或根据RRC释放消息确定，还能够根据在候选小区读取的SIB确定(对候选小区进行测量后获取)。
示例性的，基于候选小区是否支持目标切片的调整策略包括如下至少之一：
可选地，候选小区包括第一小区。
a.在第一小区支持目标切片的情况下，将第一小区的重选优先级调高为第一优先级，或将目标频点的频点优先级调高为第二优先级。
b.在第一小区不支持目标切片的情况下，跳过第一小区，或跳过目标频点，或将第一小区的重选优先级降低为第三优先级，或将目标频点的频点优先级降低为第四优先级。
其中，第一优先级高于第三优先级，第二优先级高于第四优先级。跳过目标频点指目标频点不作为重选的目标，跳过第一小区指第一小区不作为重选的目标。可选地，第一小区是重选列表中排名最高的小区、测量结果最好的小区和合适的小区之一。
可选地，终端设备根据网络指示的信息(例如本区广播或RRC施放消息指示的频点或邻小区的信息)能够判断第一小区是否支持目标切片。终端设备也可以根据在第一小区读取的SIB，判断第一小区是否支持目标切片(即对第一小区测量后获取)。
示例地，终端设备执行调整策略得到的第二/第一优先级高于第一小区/目标频点在调整前的重选优先级，第三/第四优先级低于第一小区/目标频点在调整前的重选优先级。或者，第二/第一优先级高于第一小区外的其它小区/目标频点外的其它频点的重选优先级，第三/第四优先级低于第一小区外的其它小区/目标频点外的其它频点的重选优先级。调整前的重选优先级是基于第一频点优先级确定的。
进一步的，在第一小区不支持目标切片，且目标频点针对不同小区标识配置不同的频点优先级的情况下，终端设备会跳过第一小区，或跳过目标频点。
在第一小区不支持目标切片，且目标频点针对不同小区标识配置相同的频点优先级的情况下，终端设备会将第一小区的重选优先级降低为所述第三优先级，或将所述目标频点的频点优先级降低为第四优先级。
示例地，目标切片为切片1，小区1不支持切片1，且小区1对应的频点1针对不同小区(小区标识)配置了不同的频点优先级(同频点小区的频点优先级不同)，终端设备在进行小区重选时，会跳过小区1或跳过频点1。目标切片为切片1，小区2不支持切片1，且小区2对应的频点2针对不同小区(小区标识)配置了相同的频点优先级(同频点小区的频点优先级相同)，终端设备在进行小区重选时，会将小区2的重选优先级降低为所述第三优先级，或将频点2的频点优先级降低为第四优先级。
c.在第一小区支持目标切片，且目标频点针对不同小区标识配置不同的频点优先级，且第一小区当前对应的频点优先级不为目标频点针对第一小区配置的频点优先级的情况下，跳过第一小区，或跳过目标频点。
示例地，目标切片为切片1，小区3支持切片1，且小区3对应的频点3针对不同小区(小区标识)配置了相同的频点优先级(同频点小区的频点优先级相同)，并且终端设备确定第一小区当前对应的(小区重选时使用的)频点优先级不为频点3针对第一小区配置的频点优先级，此时终端设备会跳过小区3，或跳过频点3。
示例性的，基于候选小区对应的切片信息的调整策略包括：
可选地，候选小区包括第二小区。
d.在测量到的第二小区支持目标切片但第二小区的小区标识与目标小区标识不同的情况下，跳过第二小区，或跳过目标频点，或将第二小区的重选优先级降低为第三优先级，或将目标频点的频点优先级降低为第四优先级。
其中，第二小区是按照目标频点优先级在目标频点下测量到的小区，目标小区标识是网络配置的与目标频点优先级、目标切片和目标频点对应的小区标识，终端设备能够通过切片信息获取上述信息。
示例地，终端设备根据目标频点优先级进行小区重选时，发现测量到的小区4支持与目标频点优先级对应的切片4，但是小区4的PCI和网络指示的与目标频点优先级、切片4和频点4(小区4对应的频点)对应的小区标识(小区4与该小区标识对应的小区为同频小区)不同时，终端设备会将小区4的重选优先级降低为第三优先级，或将频点4的频点优先级降低为第四优先级。
需要说明的是，上述调整策略也能够使用在小区测量和小区搜索的过程中，用于调整小区测量和小区搜索过程中使用的频点优先级，或决定是否跳过某一小区/频点，之后再基于第一测量规则或者基于上述第二测量规则进行小区搜索或小区测量。此时，该调整策略与第一测量规则会第二测量规则的结合可认为是另一种第二测量规则。

步骤702：根据第四切片信息，确定第一频点的频点优先级。
该第四切片信息能够由网络设备指示，该网络设备可以是图2中的接入网设备20。例如网络设备能够通过系统消息向终端设备指示切片信息，该系统消息包括SIB2、SIB3、SIB4以及其他(新)SIB中的至少一种。另外，网络设备还能够通过专用RRC消息实现指示切片信息，比如该专用RRC消息是RRC释放消息。第一频点为需要确定频点优先级的任一频点。

可选地，目标切片包括如下至少之一：
