Description

基于切片的小区重选方法、装置、设备及存储介质 技术领域
本申请实施例涉及通信技术，尤其涉及一种基于切片的小区重选方法、装置、设备及存储介质。
背景技术
当前，随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性，为此第三代合作伙伴计划(3rd Generation Partnership Project，简称：3GPP)国际标准组织开始研发第五代移动通信(Fifth Generation，简称：5G)。5G的主要应用场景为：增强移动超宽带(Enhanced Mobile Broadband，简称：eMBB)、低时延高可靠通信(Ultra Reliable Low Latency Communications，简称：URLLC)、大规模机器类通信(massive Machine Type Communications，简称：mMTC)。
在上述任一应用场景的具体实现中，终端设备可以根据位置移动或者业务需求进行小区选择或者重选，网络设备在配置频点的同时也可以配置频点的优先级信息。现有技术中，终端设备在进行小区选择/重选时候，终端设备选择的小区满足合适小区准则(S准则)，则终端可以选择在该小区驻留，完成小区选择。重选的目标小区满足合适小区准则且满足基于绝对频点优先级定义的重选准则条件，则终端重选到对应满足前述条件的小区，完成小区重选。
然而，现有的小区重选方法没有考虑终端设备关心的切片信息，终端设备不能保证重选的小区支持该终端设备关心的切片信息，终端设备为了发起关心的切片业务，可能需要依赖于再次发起小区重选过程或者网络设备的重定向过程，造成了额外的服务时延，不利于终端设备体验。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的说明书、权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
在目前的现有技术中，第五代移动通信(Fifth Generation，简称：5G)的主要应用场景为：增强移动超宽带(Enhanced Mobile Broadband，简称：eMBB)、低时延高可靠通信(Ultra Reliable Low Latency Communications，简称：URLLC)、大规模机器类通信(massive Machine Type Communications，简称：mMTC)。
eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于 eMBB可能部署在不同的场景中，便如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
5G网络环境中为了降低空口信令和快速恢复无线连接，快速恢复数据业务的目的，定义了一个新的无线资源控制(Radio Resource Control，RRC)状态，即RRC_INACTIVE状态。这种状态有别于RRC_IDLE和RRC_CONNECTED状态。
空闲态(RRC_IDLE)：移动性为基于用户设备(User Equipment，简称：UE)的小区选择重选，寻呼由CN发起，寻呼区域由CN配置。基站侧不存在UE AS上下文。不存在RRC连接。
连接态(RRC_CONNECTED)：存在RRC连接，基站和UE存在UE AS上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。
非激活态(RRC_INACTIVE)：移动性为基于UE的小区选择重选，存在CN-NG-RAN之间的连接，UE AS上下文存在某个基站上，寻呼由无线接入网(Radio Access Network，简称：RAN)触发，基于RAN的寻呼区域由RAN管理，网络侧知道UE的位置是基于RAN的寻呼区域级别的。
频点优先级
网络设备在配置一个频点时可以同时配置该频点优先级信息，频点优先级也可以称为绝对频点优先级，绝对频点优先级取值为0、1、2、3、4、5、6或者7，0代表优先级最低，7表示优先级最高，为了频点优先级配置的多样性，标准规定0～7每一个值又可以关联一个小数位取值，小数位取值范围为{0.2，0.4，0.6，0.8}，整数位和小数位配合总共有40种绝对频点优先级组合。
绝对频点优先级可以通过系统信息或者专用信令配置，专用信令配置的频点优先级会关联一个有效时长，在有效时长内，专用频点优先级总是覆盖系统信息广播的公共频点优先级；当有效时长超时后，终端设备只能使用公共频点优先级。
终端设备进行小区选择/重选规则
小区选择：
终端设备选择的小区满足合适小区准则(S准则)，则终端设备可以选择在该小区驻留，完成小区选择。
小区重选：
重选的目标小区满足合适小区准则且满足基于绝对频点优先级定义的重选准则条件，则终端设备重选到对应满足前述条件的小区，完成小区重选；
上述基于绝对频点优先级定义的重选准则(也称为绝对频点小区重选评估准则)包括如下三种：
- 高优先级频点小区重选准则；
- 同等优先级频点小区重选准则或者同频重选准则，也称作R准则；
- 低优先级频点小区重选准则。
切片概念简介
网络切片是一种面向业务的资源封装概念，一种网络切片通过网络切片选择支撑标识(Network Slice Selection Assistant Identity，简称：NSSAI)唯一标示，同时也对应着一种类型的资源配置。不同的核心网可以根据需求支持不同类型的网络切片，与长期演进(Long Term Evolution，简称：LTE)系统注册不同的是，终端设备在网络中使用某种切片之前需要进行该切片的注册，终端设备只有在该切片注册成功后才能发起该切片对应的会话建立过程。切片注册过程中，终端设备请求注册的NSSAI信息(Request NSSAI)通过消息5携带到接入网侧，且约束终端一次最多只能注册8个S-NSSAI(Single NSSAI)信息；核心网根据终端设备的签约信息、终端设备的Request NSSAI、本地支持的切片信息以及本地策略生成终端设备的Allowed NSSAI以及Rejected NSSAI。
终端设备也会预配置或者从核心网获取Configured NSSAI，该配置是公共陆地移动网(Public Land Mobile Network，简称：PLMN)唯一的，如果终端设备配置的某一PLMN没有配置Configured NSSAI，则使用Default NSSAI信息。
新无线(New Radio，简称：NR)系统核心网定义，一个切片对应一个S-NSSAI标识，一个S-NSSAI标识由切片类型标识(Slice/Service Type，简称：SST)和切片区分标识(Slice Differentiator，简称：SD)组成，其中切片类型标识SST占用8个比特且是必须出现的，切片区分标识SD占用24个比特且 是可选出现的。
在目前的NR系统中，小区重选方法并未考虑终端设备关心的切片信心，终端设备不能保证重选的小区支持该终端设备关心的切片信息，终端设备为了发起关心切片业务可能需要依赖于再次发起小区重选过程或者网络设备的重定向过程，造成了额外的服务时延，不利于终端设备体验。
针对上述存在的问题，本申请提供一种基于切片的小区重选方法，在该方案中，终端设备在进行小区重选时，首先获取服务小区频点关联的切片相关信息和/或至少一个邻区频点关联的切片相关信息，再基于切片相关信息进行小区的重选，以避免由于未考虑切片导致需要再次进行小区重选过程，降低终端设备的业务时延。
图1为本申请提供的基于切片的小区重选方法的应用场景示意图，如图1所示，该方案主要应用在任意终端设备中。网络设备可用于发送一些配置信息，或者切片相关信息，或者对终端设备是否采用基于切片的小区重选方案进行指示。
具体的，该方案可能涉及到网络设备以及终端设备两种执行主体，网络设备是与UE终端设备(或称为通信终端、终端)通信的设备，可以是接入网设备或者核心网设备。
该网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备可以是全球移动通信系统(Global System for Mobile Communications，简称：GSM)系统或码分多址(Code Division Multiple Access，简称：CDMA)系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，简称：LTE)系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备，或者提供卫星服务的基站等等。
终端设备包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。可以指接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
基于上述图1所示的场景，下面通过几个具体实施例对本申请提供的基于切片的小区重选方法进行详细描述。
图2为本申请提供的基于切片的小区重选方法实施例一的流程图，如图2所示，该基于切片的小区重选方法具体包括以下步骤：
S101：接收网络设备发送的服务小区频点关联的切片相关信息和/或至少一个邻区频点关联的切片相关信息。
在本步骤中，终端设备可以从网络设备获取当前的服务小区频点关联的切片相关信息和/或至少一个邻区频点关联的切片相关信息。
在一种具体实现中，终端设备可通过系统广播消息或者专用信令从网络设备获取服务小区频点关联的切片相关信息和/或所述至少一个邻区频点关联的切片相关信息。
具体来说，对服务小区频点或者至少一个邻区频点中的任一个频点，频点关联的切片相关信息至少包括切片标识信息，该切片标识信息中具体包括至少一个切片标识。
可选的，在一种具体实现中，对服务小区频点或者至少一个邻区频点中的任一个频点，频点关联的切片相关信息还包括至少一个切片标识关联的切片优先级信息。
可选的，在另一种具体实现中，该切片优先级信息是按照频点粒度或者物理小区标识(Physical Cell Identity，简称：PCI)粒度配置的。
具体实现中，切片优先级信息中可以包括切片标识信息中的一个或者多个切片标识对应的切片优先级。存在切片优先级信息包括全部切片标识对应的切片优先级，也可能切片优先级信息中只包括切片标识信息中的一个或者几个切片标识对应的切片优先级，对此本方案不做限制。
在终端设备进行小区重选过程中，若发现任一频点关联的切片相关信息中存在一个或者多个切片标识未配置切片优先级信息，则可将未配置切片优先级信息的所述一个或者多个切片标识对应的切片优先级设置为最高等级或者最低等级。
S102：根据服务小区频点关联的切片相关信息和/或至少一个邻区频点关联的切片相关信息，确定目标重选小区。
在本步骤中，终端设备在获取到相关的频点关联的切片相关信息之后，则可以根据该服务小区频点关联的切片相关信息和/或至少一个邻区频点关联的切片相关信息，进行小区重选，最终确定出目标重选小区。
终端设备基于切片相关信息进行小区重选包括多种实现方式，下面对具体的重选方式进行举例说明：
第一种方式
第一轮重选评估，终端设备可以对待评估的支持目标切片标识的至少一个邻区，根据每个邻区的邻区频点对应的绝对频点优先级从高至低的顺序依次进行小区重选评估，以确定出唯一的目标重选小区。
若根据邻区频点对应的绝对频点优先级确定出了唯一的目标重选小区，则结束该小区重选过程，否则进行第二轮重选评估。
第二轮重选评估，若根据邻区频点对应的绝对频点优先级未确定出唯一的目标重选小区(即第一轮重选评估过程不能唯一确定一个目标重选小区)，则对邻区频点对应的绝对频点优先级相同的至少两个邻区，根据邻区频点关联的目标切片标识对应的切片优先级从高至低的顺序依次进行小区重选评估，以确定出唯一的目标重选小区。
若根据邻区频点关联的目标切片标识对应的切片优先级确定出唯一的目标重选小区，则结束该小区重选过程，否则进行第三轮重选评估。
第三轮重选评估，若根据邻区频点关联的目标切片标识对应的切片优先级未确定出唯一的目标重选小区(即第二轮重选评估过程不能唯一确定一个目标重选小区)，则对邻区频点对应的绝对频点优先级相同且邻区频点关联的目标切片标识对应的优先级也相同的至少两个邻区，根据所述至少两个邻区的频点对应的绝对频点小区重选评估准则进行小区重选评估，以确定出唯一的目标重选小区。
若根据绝对频点小区重选评估准则选出了唯一的目标重选小区，则结束该小区重选过程，若按照这种规则选择出的小区数量还是两个或者两个以上，则需要再进行一轮重选评估。
第四轮重选评估，若满足所述绝对频点小区重选评估准则的小区数量大于一个(即满足所述绝对频点小区重选评估准则的小区仍然有至少两个)，则根据同等优先级频点小区重选准则或者同频重选准则(也称为R准则)对小区进行排位，并将排位最高的小区作为所述目标重选小区。
第二种方式
第一轮重选评估，终端设备对待评估的支持目标切片标识的至少一个邻区，根据每个邻区的邻区频点关联的目标切片标识对应的切片优先级从高至低的顺序依次进行小区重选评估，以确定出唯一的目标重选小区。
若根据邻区频点关联的目标切片标识对应的切片优先级确定出唯一的目标重选小区，则结束该小区重选过程，否则进入第二轮重选评估过程。
第二轮重选评估，若根据邻区频点关联的目标切片标识对应的切片优先级未确定出唯一的目标重选小区(即第一轮重选评估过程不能唯一确定一个目标重选小区)，则对邻区频点关联的目标切片标识对应的优先级相同的至少两个邻区，根据每个邻区的邻区频点对应的绝对频点优先级从高至低的顺序依次进行小区重选评估，以确定出唯一的目标重选小区。
若根据邻区频点对应的绝对频点优先级确定出唯一的目标重选小区，则结束该小区重选过程。否则进入第三轮重选评估过程。
第三轮重选评估，若根据邻区频点对应的绝对频点优先级未确定出唯一的目标重选小区(即第二 轮重选评估过程不能唯一确定一个目标重选小区)，则对邻区频点关联的目标切片标识对应的切片优先级相同且邻区频点对应的绝对频点优先级也相同的至少两个邻区，根据所述至少两个邻区的频点对应的绝对频点小区重选评估准则进行小区重选评估，以确定出唯一的目标重选小区。
若满足所述绝对频点小区重选评估准则的小区数量只有一个，即唯一的确定出了目标重选小区，则结束该小区重选过程，否则，则还需要再进行下一轮重选评估过程。
第四轮重选评估，若满足所述绝对频点小区重选评估准则的小区数量大于一个(即满足所述绝对频点小区重选评估准则的小区仍然有至少两个)，则根据同等优先级频点小区重选准则或者同频重选准则(也称为R准则)对小区进行排位，并将排位最高的小区作为所述目标重选小区。
第三种方式
终端设备对待评估的支持目标切片标识的至少一个邻区，根据每个邻区的邻区频点关联的目标切片标识对应的切片优先级的相对高低情况为邻区频点对应的绝对频点优先级进行赋值。根据赋值后的每个邻区的邻区频点对应的绝对频点优先级从高至低的顺序依次进行小区重选评估，以确定出唯一的目标重选小区。
若根据赋值后的邻区频点对应的绝对频点优先级确定出唯一的目标重选小区，则结束该小区重选评估过程，否则则需要根据基于绝对频点优先级定义的重选准则进行小区重选。可以具体实现为：
若根据赋值后的邻区频点对应的绝对频点优先级未确定出唯一的目标重选小区，则对邻区频点对应的绝对频点优先级相同的至少两个邻区，根据所述至少两个邻区的频点对应的绝对频点小区重选评估准则进行小区重选评估，以确定出唯一的目标重选小区；
若满足所述绝对频点小区重选评估准则的小区数量大于一个，则根据同等优先级频点小区重选准则或者同频重选准则(也称为R准则)对小区进行排位，并将排位最高的小区作为所述目标重选小区。
在采用第三种方式进行小区重选的过程中，应理解该方案的实质是基于每个频点对应的目标切片标识对应的切片优先级高低进行了小区选择。只是在实现过程中，采用绝对频点优先级进行小区选择之前，使用各邻区频点上目标切片标识对应的切片优先级的相对高低情况为各邻区频点对应的绝对频点优先级进行重新赋值，每个邻区频点得到了新的绝对频点优先级。
在该方案的具体实现中，对于各邻区频点对应的绝对频点优先级的赋值，可以直接将频点原来的绝对频点优先级替换为该频点上目标切片标识对应的切片优先级，也可以根据频点上目标切片标识对应的切片优先级进行排序或者确定相对的优先级高低即可，对此本方案不做限制。
应理解，在上述任一方式中，绝对频点小区重选评估准则包括如下至少一种：
高优先级频点小区重选评估准则；
低优先级频点小区重选评估准则；
同频或者同优先级频点小区重选评估准则，也称为R准则。
上述的几种小区重选方案均是基于切片相关信息进行的小区重选，在每种方式中均需要应用到目标切片标识。对于终端设备来说，则需要在具体应用到目标切片标识之前，确定出该目标切片标识。
在该方案的一种具体实现中，终端设备可以从接入层(Access Stratum，简称：AS，也称为AS层)获取该目标切片标识，该目标切片标识为所述AS层从上层直接获取得到的，或者，为AS层从上层提供的多个切片标识中选择的。
可选的，该上层可以是非接入层(Non-Access Stratum，简称：NAS)，也称为NAS层。
具体的，如果目标切片标识是AS层从上层提供的多个切片标识中选择出的一个，则该终端设备还需要从上层获取多个切片标识对应的切片优先级信息，然后根据多个切片标识对应的切片优先级信息，确定目标切片标识。
本实施例提供的基于切片小区的重选方法，通过网络设备获取各小区频点对应的切片相关信息，再基于切片相关信息进行小区的重选。即终端设备可以基于对切片的喜好和需求进行小区重选，避免由于切片问题再次进行重选，降低终端设备的业务时延，提升用户体验。
在前述实施例的基础上，对于终端设备来说，在进行小区重选时是否采用基于切片的小区重选方法需要预先进行确定，具体的，终端设备可以通过以下方式中的至少一种确定是否采用基于切片的小区重选方法：
第一种方式，图3为本申请提供的基于切片的小区重选方法一实例的流程图，如图3所示，该基于切片的小区重选方法还包括以下步骤：
S201：网络设备向终端设备发送第一指示信息。
S202：基于网络设备发送的第一指示信息，确定是否应用基于切片的小区重选方法。
在该方案中，网络设备向终端设备发送第一指示信息，终端设备接收网络设备发送的第一指示信息，然后基于网络设备发送的第一指示信息，确定是否应用基于切片的小区重选方法，该第一指示信息用于指示是否应用基于切片的小区重选方法。
该第一指示信息为一种开关配置信息，即直接指示应用基于切片的小区重选方法或者不应用基于切片的小区重选方法。
或者，所述第一指示信息用于指示确定是否应用基于切片的小区重选方法中的任一种，如果所述第一指示信息指示终端设备应用一种具体的基于切片的小区重选方法，则终端设备应用对应基于切片的小区重选方法；否则，在所述第一指示信息不出现或者所述第一指示信息取值不指向任何一种有效的基于切片的小区重选方法时，则终端设备不应用基于切片的小区重选方法。
网络设备可以通过系统广播消息或者专用信令向终端设备配置该第一指示信息，对此本方案不做限制。
可选的，在所述第一指示信息通过系统广播消息承载时，所述系统广播消息可以是SIB1、SIB2、SIB3、SIB4、SIB5中的任意一种。
第二种方式，终端设备可根据自身的能力信息，确定是否应用基于切片的小区重选方法，该能力信息用于指示是否应用基于切片的小区重选方法。
第三种方式，基于预配置约定，确定是否应用基于切片的小区重选方法。该方案中，终端设备可以根据协议或者出厂设置中的约定，确定应用或者不应用该基于切片的小区重选方法。
在前述任一实施例的具体实现中，终端设备要基于切片进行小区重选，则需要对服务小区和/或至少一个邻区进行测量，以获取测量结果，才可以根据切片相关信息进行小区重选。
一般来说，终端设备需要在满足小区测量条件之后才对各个小区进行测量，本方案中为了能够应用基于切片的小区重选方案，设置了不满足测量条件但是可以触发小区测量过程的预设事件。
即对于终端设备来说，可根据预设事件启动未满足测量条件但支持目标切片标识的邻区频点测量过程；其中，所述预设事件包括以下至少一项：
(1)，确定应用基于切片的小区重选方法(即虽然未满足测量条件，但是终端设备已确定采用基于切片的小区重选方法，则可主动进行小区测量)；
(2)，终端设备驻留到一个新的小区；
(3)，邻区频点上支持所述目标切片标识；
(4)，当前的服务小区测量结果小于或者等于第一阈值，所述第一阈值通过系统广播消息或者专用信令获取；
(5)，从已有测量结果的待评估邻区中无法确定出目标重选小区，且存在未满足测量启动条件但支持所述目标切片标识的邻区频点。
在前述的5个预设事件中，当出现了其中一个事件或者一个以上事件时，则可以在不满足测量条件时进行小区测量。
可选的，上述事件可能存在组合使用的情况，例如：事件(3)和事件(4)组合使用，事件(4)和事件(5)组合使用，本申请对于这种组合事件方式不做限定。
应理解，事件(1)至(4)均为前置条件，也就是说需要在小区重选过程之前，如果发生这些事件则进行小区测量，得到测量结果。然后再基于切片相关信息以及测量结果进行小区的重选。事件(5)有所不同，为后置条件，也就是说在进行小区重选过程中，发现无法从已有测量结果的待评估邻区中无法确定出目标重选小区，并且还有其他的邻区频点能够支持目标切片标识，那么则可以对该些邻区进行小区测量，进一步根据测量结果进行小区重选。
在该方案的一种具体实现中，是否采用前述的预设事件触发小区测量可以由网络设备进行配置。例如：图4为本申请提供的基于切片的小区重选方法另一实例的流程图，如图4所示，该基于切片的小区重选方法还包括以下步骤：
S301：网络设备向终端设备发送第二指示信息。
S302：终端设备根据第二指示信息确定是否应用根据预设事件启动未满足测量条件但支持目标切片标识的邻区频点测量过程。
在该方案中，终端设备接收所述网络设备发送的第二指示信息，所述第二指示信息用于指示所述终端设备是否应用根据预设事件启动未满足测量条件但支持目标切片标识的邻区频点测量过程的方法。
应理解，在该方案的具体实现中，该第二指示信息通过系统广播消息或者专用信令配置。
综上所述，本申请提供的基于切片的小区重选方法，在进行小区重选时终端设备需要确定出目标 切片标识，从网络设备获取关联的切片相关信息，在此基础上基于对小区的测量结果，切片相关信息以及目标切片标识，进行小区重选评估，最终确定目标重选小区，有效避免了没有考虑切片信息导致终端设备选择的小区不支持其关心切片的业务的问题，也避免了重新发起小区重选或者重定向过程，降低了服务时延，提高了用户体验。
基于前述的各个实施例，下面通过具体的实施例对本方案中涉及的以下几个过程进行详细说明：
一、终端设备确定目标切片标识；
二、服务小区频点和/或至少一个邻区频点关联的切片相关信息；
三、具体的小区重选方案；
四、确定是否应用所述基于切片的小区重选方法；
五、根据预设事件开启未满足测量启动条件但支持所述目标切片标识的邻区频点测量过程。
一、终端设备确定目标切片标识
目标切片标识由终端设备AS层从上层直接获取或者所述目标切片标识由所述终端设备AS层从上层提供的多个切片标识中选择一个。
方式一：目标切片标识由所述终端设备AS层从上层直接获取。该方式下，终端设备AS层从上层直接获取所述目标切片标识。
方式二：目标切片标识由所述终端设备AS层从上层提供的多个切片标识中选择一个得到。
方式二的一种实现方式中，终端设备AS层从上层获取的多个切片标识均没有关联切片优先级信息，此时，终端设备基于实现从上层提供的多个切片标识中随机选择一个作为目标切片标识。
方式二的另一种实现方式下，终端设备AS层从上层获取的多个切片标识关联了切片优先级信息，如表1所示：
表1终端设备AS层从上层获取的多个切片标识关联了切片优先级信息示意
Figure PCTCN2021092287-appb-000001
如表1所示，上层提供切片标识信息时同时提供了该切片标识信息关联的切片优先级信息，每个切片标识信息关联的切片优先级信息可以相同或者不同，允许上层提供的部分切片标识信息没有关联的切片优先级信息，此时，认为这些没有关联切片优先级信息的切片标识切片优先级信息为最高或者最低。
终端设备根据切片优先级信息从上层提供的多个切片标识中选择一个作为目标切片标识。
示例性的，前述上层可以是NAS层。
在本申请中，切片标识的含义：切片标识可以是代表一组S-NSSAI/NSSAI的切片组标识或者是标准S-NSSAI标识的SST部分或者是标准S-NSSAI标识的SD部分或者是基于标准S-NSSAI/NSSAI标识经过算法映射后的标识。
二、服务小区频点和/或至少一个邻区频点关联的切片相关信息
终端设备在进行小区重选时，可以将待评估的支持目标切片标识的至少一个邻区的频点作为目标频点集合进行处理，目标频点集合各频点支持的切片相关信息至少包括切片标识信息，所述切片标识信息包含至少一个切片标识。
可选的，目标频点集合各频点支持的切片相关信息还包括所述至少一个切片标识关联的切片优先级信息。此时，所述切片优先级信息可按照频点粒度配置或者按照PCI粒度配置。
表2切片优先级信息按照频点粒度配置
Figure PCTCN2021092287-appb-000002
如表2所述，以每个邻区频点关联3个切片标识为例进行说明，本申请并不限制每个邻区频点实际关联的切片标识个数。此时，同一个切片标识在同一个邻区频点下的切片优先级是唯一的，因此认为切片优先级信息按照频点粒度配置。
表3对于切片优先级信息按照PCI粒度配置
Figure PCTCN2021092287-appb-000003
如表3所述，以每个邻区频点关联3个PCI为例进行说明，本申请并不限制每个邻区频点实际关联的PCI个数。一个PCI下关联一个切片相关信息，所述切片相关信息包含一个或者多个切片标识以及一个或者多个切片标识关联的切片优先级信息，每一个切片标识关联一个切片优先级信息。此时，同一个切片标识在同一个邻区频点下的任意一个PCI内的切片优先级是唯一的，但同一个切片标识在同一个邻区频点下的不同PCI之间的切片优先级不一定是唯一的，因此认为切片优先级信息按照PCI粒度配置。
说明1：表2和表3中均允许邻区频点关联的部分切片标识不配置对应关联的切片优先级信息，此时，可将未配置优先级信息的部分切片标识对应的切片优先级确定为最高等级或者最低等级。
说明2：目标频点集合中的各频点支持的切片相关信息通过系统广播消息或者专用信令从网络设备获取。
说明3：服务小区频点对应的切片相关信息获取过程和表2或表3过程类似，此处不再赘述。
三、具体的小区重选方案
根据实施例一可知终端设备基于切片进行小区重选的方式至少有三种，下面对三种分别进行举例说明。
方式1，对应于实施例一中的第一种方式的一种特例，在各频点关联的切片相关信息只包括切片标识信息时，给出如下假设：
终端设备的目标切片标识为切片标识1；
服务小区频点为F1，绝对频点优先级为4，支持的切片为{切片标识1、切片标识2、切片标识3}；
邻区频点F2，绝对频点优先级为6，支持的切片为{切片标识1、切片标识2、切片标识3}；
邻区频点F3，绝对频点优先级为6，支持的切片为{切片标识2、切片标识3}；
邻区频点F4，绝对频点优先级为2，支持的切片为{切片标识1、切片标识2、切片标识3}
邻区频点F5，绝对频点优先级为5，支持的切片为{切片标识1、切片标识2、切片标识3}。
小区重选评估准备阶段：在不考虑根据预设事件开启未满足测量启动条件但支持所述目标切片标识的邻区频点测量过程时，由于F1是服务频点(按照规律一直测量)，F2、F3和F5为高优先级频点(按照规律一直测量)，按照现有技术要求，小区重选评估准备阶段只能测量得到在F1～F3以及F5上部署的小区测量结果，邻区频点F4为低优先级频点，不进行测量。
第一轮重选评估：根据每个邻区的邻区频点对应的绝对频点优先级从高至低的顺序依次进行小区重选评估，第一轮重选评估后优先评估F2和F3上的小区，由于不能确定出唯一的目标重选小区，需要进行第二轮重选评估。
第二轮重选评估：第一轮重选评估过程不能唯一确定一个目标重选小区，则对邻区频点对应的绝对频点优先级相同的至少两个邻区，根据邻区频点关联的目标切片标识对应的切片优先级从高至低的顺序依次进行小区重选评估，以确定出唯一的目标重选小区，由于F3不支持目标切片标识(切片标识1)，因而排除F3上测量得到的小区，剩下优先评估F2上的小区，由于F2对应的绝对频点优先级为高优先级，需要根据高优先级频点小区重选评估准则进行评估，在该小区满足高优先级频点小区重选评估准则条件时，该小区被确定为目标重选小区；否则，排除F2上的小区。
在F2上的小区被排除后，应该回到第一轮重选评估过程，接着评估F5上的小区，以此类推，直到确定唯一的目标重选小区，完成小区重选。
方式2，对应于实施例一中的第一种方式，在各频点关联的切片相关信息包括切片标识信息以及至少一个切片标识关联的切片优先级信息时，给出如下假设：
终端设备的目标切片标识为切片标识1；
服务小区频点为F1，绝对频点优先级为4，支持的切片相关信息为{{切片标识1，切片优先级为3}、{切片标识2，切片优先级为4}、{切片标识3，切片优先级为5}}；
邻区频点F2，绝对频点优先级为6，支持的切片相关信息为{{切片标识1，切片优先级为3}、{切片标识2，切片优先级为4}、{切片标识3，切片优先级为5}}；
邻区频点F3，绝对频点优先级为6，支持的切片相关信息为{{切片标识1，切片优先级为2}、{切片标识2，切片优先级为3}、{切片标识3，切片优先级为4}}；
邻区频点F4，绝对频点优先级为6，支持的切片相关信息为{{切片标识2，切片优先级为4}、{切片标识3，切片优先级为5}}；
邻区频点F5，绝对频点优先级为2，支持的切片相关信息为支持的切片相关信息为{{切片标识1，切片优先级为4}、{切片标识2，切片优先级为5}、{切片标识3，切片优先级为6}}。
小区重选评估准备阶段：在不考虑根据预设事件开启未满足测量启动条件但支持所述目标切片标识的邻区频点测量过程时，由于F1是服务频点(按照规律一直测量)，F2到F4为高优先级频点(按照规律一直测量)，按照现有技术要求，小区重选评估中只能测量得到在F1～F4上部署的小区测量结果。F5为低优先级频点，不进行测量。
第一轮重选评估：根据每个邻区的邻区频点对应的绝对频点优先级从高至低的顺序依次进行小区重选评估，第一轮重选评估后优先评估F2～F4上的小区，由于不能确定出唯一的目标重选小区，则需要进行第二轮重选评估。
第二轮重选评估：第一轮重选评估没有确定出唯一的目标重选小区，则对邻区频点对应的绝对频点优先级相同的至少两个邻区，根据邻区频点关联的目标切片标识对应的切片优先级从高至低的顺序依次进行小区重选评估。在该评估过程中：同时满足小区对应频点支持所述目标切片标识以及支持所述目标切片标识的频点上所述目标切片标识对应的切片优先级最高，则被优先进行重选评估，由于F3上所述目标切片标识对应的切片优先级不是最高，F4上不支持目标切片标识(切片标识1)，因而在这一轮将在F3和F4上测量得到的小区排除，对F2上的小区进行优先评估，若能够确定出唯一的目标重选小区，则结束小区重选过程，若F2上不能确定出唯一的目标重选小区，则需要进行第三轮重选评估。
第三轮重选评估：对邻区频点对应的绝对频点优先级相同且邻区频点关联的目标切片标识对应的优先级也相同的至少两个邻区，根据所述至少两个邻区的频点对应的绝对频点小区重选评估准则进行小区重选评估。在该过程中，由于F2对应的绝对频点优先级为高优先级，需要根据高优先级频点小区重选评估准则进行评估，在该小区满足高优先级频点小区重选评估准则条件时，该小区被确定为目标重选小区；否则，排除F2上的小区。
如果在F2频点上确定出满足高优先级频点小区重选评估准则条件的小区数量还在两个或两个以上，则还需要进行第四轮重选评估。
第四轮重选评估：根据同等优先级频点小区重选准则或者同频重选准则(也称为R准则)对F2频点上的小区进行排位，将排位最高的小区确定为目标重选小区。
由于本实例中第二轮重选评估之后，只剩下邻区频点F2上测量得到的小区，如果在第三轮重选评估过程中，将F2也排除，则重新进行第二轮重选评估，对目标切片标识对应的优先级在第二的邻区频点F3上测量得到的小区进行重选评估，并重复后续的步骤，依此类推，直到选择出唯一的目标重选小区，完成小区重选。
方式2示出的这种小区重选过程中，其总体思路是：首先根据邻区的绝对频点优先级进行目标小区重选，再进一步根据邻区频点关联的目标切片标识对应的切片优先级进一步进行小区重选评估，最后再采用绝对频点小区重选评估准则进一步进行小区重选评估，属于实施例一中的第一种方式。
方式3，对应于实施例一中的第二种方式，在各频点关联的切片相关信息包括切片标识信息以及至少一个切片标识关联的切片优先级信息时，给出如下假设：
终端设备的目标切片标识为切片标识1；
服务小区频点为F1，绝对频点优先级为4，支持的切片相关信息为{{切片标识1，切片优先级为3}、{切片标识2，切片优先级为4}、{切片标识3，切片优先级为5}}；
邻区频点F2，绝对频点优先级为6，支持的切片相关信息为{{切片标识1，切片优先级为4}、{切片标识2，切片优先级为4}、{切片标识3，切片优先级为5}}；
邻区频点F3，绝对频点优先级为6，支持的切片相关信息为{{切片标识1，切片优先级为2}、{切片标识2，切片优先级为3}、{切片标识3，切片优先级为4}}；
邻区频点F4，绝对频点优先级为6，支持的切片相关信息为{{切片标识2，切片优先级为4}、{切片标识3，切片优先级为5}}；
邻区频点F5，绝对频点优先级为3，支持的切片相关信息为支持的切片相关信息为{{切片标识1，切片优先级为4}、{切片标识2，切片优先级为5}、{切片标识3，切片优先级为6}}。
小区重选准备过程：在考虑根据预设事件开启未满足测量启动条件但支持所述目标切片标识的邻区频点测量过程时，由于F1是服务频点(按照规律一直测量)，F2到F4为高优先级频点(按照规律一直测量)，F5虽然是低优先级频点，但是支持目标切片标识，可以根据预设事件触发测量，按照现有技术要求，小区重选评估中可以测量得到在F1～F5上部署的小区测量结果。
第一轮重选评估：根据每个邻区的邻区频点关联的目标切片标识对应的切片优先级从高至低的顺序依次进行小区重选评估，以确定出唯一的目标重选小区。对支持目标切片标识的至少一个邻区，按照切片优先级从高至低的顺序依次评估后确定重选小区，第一轮评估后剩下邻区频点F2和F5继续评估。具体的，由于F4不支持目标切片标识，F3虽然支持目标切片标识但是其目标切片标识对应的切片优先级低于服务小区中的切片优先级，因此将F3-F4的频点排除。在第一轮重选评估之后，优先对频点F2和F5上的小区进行评估。由于不能确定出唯一的目标重选小区，则需要进行第二轮重选评估。
第二轮重选评估：对邻区频点关联的目标切片标识对应的优先级相同的至少两个邻区，根据每个邻区的邻区频点对应的绝对频点优先级从高至低的顺序依次进行小区重选评估，以确定出唯一的目标重选小区。具体的：由于F5上的绝对频点优先级为3低于F2的绝对频点优先级6，因而可暂时排除F5上测量得到的小区，优先对F2上的小区进行评估，若能够确定出唯一的目标重选小区，则结束小区重选过程，若F2上不能确定出唯一的目标重选小区，则需要进行第三轮重选评估。
第三轮小区重选评估：根据所述至少两个邻区的频点对应的绝对频点小区重选评估准则进行小区重选评估。在该过程中，由于F2对应的绝对频点优先级为高优先级，需要根据高优先级频点小区重选评估准则进行评估，在该小区满足高优先级频点小区重选评估准则条件时，该小区被确定为目标重选小区；否则，排除F2上的小区。
如果在F2频点上确定出满足高优先级频点小区重选评估准则条件的小区数量还在两个或两个以上，则还需要进行第四轮重选评估。
第四轮重选评估：根据同等优先级频点小区重选准则或者同频重选准则(也称为R准则)对F2频点上的小区进行排位，将排位最高的小区确定为目标重选小区。
由于本实例中第二轮重选评估之后只剩下在频点F2上测量得到的小区，
如果在第三轮重选评估过程中，将F2也排除，则重新进行第二轮重选评估，对绝对频点优先级较低的F5上测量得到的小区进行重选评估，并重复后续的步骤，依此类推，直到选择出唯一的目标重选小区，完成小区重选。
方式3示出的这种小区重选过程中，其总体思路是：首先根据邻区频点关联的目标切片标识对应的切片优先级顺序依次进行小区重选评估，再进一步根据邻区频点的绝对频点优先级进行目标小区重选，最后再采用绝对频点小区重选评估准则进一步进行小区重选评估，属于实施例一中的第二种方式。
方式4，对应于实施例一中的第三种方式，在各频点关联的切片相关信息包括切片标识信息以及至少一个切片标识关联的切片优先级信息时，给出如下假设：
终端设备的目标切片标识为切片标识1；
服务小区频点为F1，绝对频点优先级为3，支持的切片相关信息为{{切片标识1，切片优先级为3}、{切片标识2，切片优先级为4}、{切片标识3，切片优先级为5}}；
邻区频点F2，绝对频点优先级为6，支持的切片相关信息为{{切片标识1，切片优先级为4}、{切片标识2，切片优先级为4}、{切片标识3，切片优先级为5}}；
邻区频点F3，绝对频点优先级为6，支持的切片相关信息为{{切片标识1，切片优先级为2}、{切片标识2，切片优先级为3}、{切片标识3，切片优先级为4}}；
邻区频点F4，绝对频点优先级为6，支持的切片相关信息为{{切片标识1，切片优先级为3}、{切片标识2，切片优先级为5}}；
小区重选评估准备阶段：在不考虑根据预设事件开启未满足测量启动条件但支持所述目标切片标识的邻区频点测量过程时，由于F1是服务频点(按照规律一直测量)，F2到F4为高优先级频点(按照规律一直测量)，小区重选评估中能测量得到在F1～F4上部署的小区测量结果，当前F2-F4的绝对频点优先级均相同，也可以是不同的，本方案对此不做限制。
本方案与前述的几个实例的方案有所不同，从实现步骤上可以分为两个步骤：根据目标切片标识对应的切片优先级对绝对频点优先级进行赋值，根据赋值后的绝对频点优先级进行小区重选。
重选评估步骤一：对支持目标切片标识的F1-F4，根据服务小区频点和/或邻区频点关联的目标切片标识对应的切片优先级的相对高低情况为服务小区频点和/或邻区频点对应的绝对频点优先级进行赋值。
赋值后的F1-F4的绝对频点优先级如下：
服务小区频点F1，绝对频点优先级为3。
邻区频点F2，绝对频点优先级为4；
邻区频点F3，绝对频点优先级为2；
邻区频点F4，绝对频点优先级为3。
或者，不直接进行赋值，而是得到赋值后的绝对频点优先级的相对高低，赋值后：邻区频点F2的绝对频点优先级>邻区频点F4的绝对频点优先级＝服务小区频点F1的绝对频点优先级>邻区频点F3的绝对频点优先级。
重选评估步骤二，根据赋值后的每个邻区的邻区频点对应的绝对频点优先级从高至低的顺序依次进行小区重选评估，以确定出唯一的目标重选小区。
在基于赋值后的绝对频点优先级从高至低的顺序确定目标重选小区时候，需要至少一轮的小区重选评估，具体如下：
第一轮重选评估，F3和F4赋值后的绝对频点优先级低于F2赋值后的绝对频点优先级，因此将F3和F4的频点上的小区排除。首先对赋值后的绝对频点优先级最高的F2频点上的小区进行评估。
在该过程中，由于F2对应的绝对频点优先级为高优先级，需要根据高优先级频点小区重选评估准则进行评估，在该小区满足高优先级频点小区重选评估准则条件时，该小区被确定为目标重选小区；否则，排除F2上的小区。
如果在F2频点上确定出满足高优先级频点小区重选评估准则条件的小区数量还在两个或两个以上，则还需要进行第二轮重选评估。
第二轮重选评估：根据同等优先级频点小区重选准则或者同频重选准则(也称为R准则)对F2频点上的小区进行排位，将排位最高的小区确定为目标重选小区。
由于本实例中步骤二第一轮之后，优先对邻区频点F2上测量得到的小区进行了重选评估，如果未能在F2上确定出唯一的目标重选小区，则可以重复该步骤二中的第一轮重选评估过程，对赋值后绝对频点优先级在第二的邻区频点F4上测量得到的小区进行重选评估，并重复后续的步骤，依此类推，直到选择出唯一的目标重选小区，完成小区重选。
方式4示出的这种小区重选过程中，其总体思路是：首先根据支持目标切片标识的切片优先级对邻区频点的绝对频点优先级进行重新赋值，并在赋值后根据邻区频点的绝对频点优先级进行目标小区重选，最后再采用绝对频点小区重选评估准则进一步进行小区重选评估，属于实施例一中的第三种方式。
四、确定是否应用所述基于切片的小区重选方法(该过程属于可选过程)
对于前述任一实施例提供的基于切片的小区重选方法，终端设备首先需要确定是否应用该基于切片的小区重选方法。具体的可以采用以下方式中的至少一种进行确定：
基于网络设备发送的第一指示信息，确定是否应用基于切片的小区重选方法，所述第一指示信息用于指示是否应用基于切片的小区重选方法；
根据所述终端设备的能力信息，确定是否应用基于切片的小区重选方法，所述能力信息用于指示是否应用基于切片的小区重选方法；
基于预配置约定，确定是否应用基于切片的小区重选方法。
其中，在终端设备基于所述第一指示信息确定是否应用基于切片的小区重选方法时，所述第一指示信息可通过系统广播消息或者专用信令配置。
基于预配置约定指的是协议默认方式确定，即：不需要网络设备向终端设备提供显性配置信息。
五、根据预设事件开启未满足测量启动条件但支持所述目标切片标识的邻区频点测量过程(该过程属于可选过程)
终端设备可根据预设事件开启未满足测量启动条件但支持所述目标切片标识的邻区频点测量过程，所述预设事件包括如下事件中的至少一项：
确定应用基于切片的小区重选方法；
终端设备驻留到一个新的小区；
邻区频点上支持所述目标切片标识；
当前的服务小区测量结果小于或者等于第一阈值，所述第一阈值通过系统广播消息或者专用信令获取；
从已有测量结果的待评估邻区中无法确定出目标重选小区，且存在未满足测量启动条件但支持所述目标切片标识的邻区频点；
在具体的实现中，是否采用根据预设事件触发为满足测量条件时的邻区测量，则可以通过网络设备的指示来确定。具体的，网络设备可向终端设备发送第二指示信息，终端设备接收网络设备发送的第二指示信息，所述第二指示信息用于指示所述终端设备是否应用所述根据预设事件开启未满足测量启动条件但支持所述目标切片标识的邻区频点测量过程的方法，其中，所述第二指示信息通过系统广播消息或者专用信令配置。
综合上述各个实施例，本申请提供一种基于切片的小区重选方法，通过该方法，终端设备可以基于自身切片喜好和需求进行小区重选，降低了终端业务时延，提升了用户体验度。
图5为本申请提供的基于切片的小区重选装置实施例一的结构示意图，如图5所示，该基于切片的小区重选装置10包括：
接收模块11，用于接收网络设备发送的服务小区频点关联的切片相关信息和/或至少一个邻区频点关联的切片相关信息；

本实施例提供的基于切片的小区重选装置，用于执行前述方法实施例中终端设备侧的技术方案，其实现原理和技术效果类似，在进行小区重选时考虑切片相关信息，降低终端设备的业务时延，提高用户体验。
在该基于切片的小区重选装置10的一种具体实现中，所述处理模块12具体用于：

若根据邻区频点关联的目标切片标识对应的切片优先级未确定出唯一的目标重选小区，则对邻区频点对应的绝对频点优先级相同且邻区频点关联的目标切片标识对应的优先级也相同的至少两个邻区，根据所述至少两个邻区的频点对应的绝对频点小区重选评估准则进行小区重选评估，以确定出唯一的目标重选小区；
若满足所述绝对频点小区重选评估准则的小区数量大于一个，则根据R准则对小区进行排位，并将排位最高的小区作为所述目标重选小区。
可选的，在该基于切片的小区重选装置10的另一种具体实现中，所述处理模块12具体用于：
