请参考图1，其示出了本申请一个实施例提供的网络架构100的示意图。该网络架构100可以包括：终端设备10、接入网设备20和核心网设备30。
终端设备10可以指UE(User Equipment，用户设备)、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、无线通信设备、用户代理或用户装置。可选地，终端设备10还可以是蜂窝电话、无绳电话、SIP(Session Initiation Protocol，会话启动协议)电话、WLL(Wireless Local Loop，无线本地环路)站、PDA(Personal Digita1Assistant，个人数字处理)、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，5GS(5th Generation System，第五代移动通信系统)中的终端设备或者未来演进的PLMN(Pub1ic Land Mobi1e Network，公用陆地移动通信网络)中的终端设备等，本申请实施例对此并不限定。为方便描述，上面提到的设备统称为终端设备。终端设备10的数量通常为多个，每一个接入网设备20所管理的小区内可以分布一个或多个终端设备10。在本申请实施例中，“终端设备”和“UE”通常表达同一含义，两者可以混用，但本领域技术人员可以理解其含义。
接入网设备20是一种部署在接入网中用以为终端设备10提供无线通信功能的设备。接入网设备20可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备10提供无线通信功能的装置统称为接入网设备。可选地，通过接入网设备20，终端设备10和核心网设备30之间可以建立通信关系。示例性地，在LTE(Long Term Evolution，长期演进)系统中，接入网设备20可以是EUTRAN(Evolved Universal Terrestrial Radio Access Network，演进的通用陆地无线网)或者EUTRAN中的一个或者多个eNodeB；在5G NR系统中，接入网设备20可以是RAN(Radio Access Network，无线接入网)或者RAN中的一个或者多个gNB。在本申请实施例中，所述的“接入网实体”除特别说明之外，是指接入网设备20，如基站。
核心网设备30是部署在核心网中的设备，核心网设备30的功能主要是提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。例如，5G NR系统中的核心网设备可以包括 NSSF(Network Slice Selection Function，网络切片选择功能)实体、AMF(Access and Mobility Management Function，接入和移动性管理功能)实体、SMF(Session Management Function，会话管理功能)实体、UPF(User Plane Function，用户面功能)实体和TCE(Trace Collection Entity，跟踪采集实体)等设备(或者说功能实体)。在本申请实施例中，所述的“核心网实体”除特别说明之外，是指核心网设备30。

在介绍本申请技术方案之前，先对本申请涉及的一些背景技术知识进行介绍说明。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
1.切片(slice)
垂直市场对无线通信的强劲需求是有目共睹的，为了满足垂直行业对延迟、移动性、可靠性、位置精度等方面的需求，RAN需要对如何在接入网支持垂直业务进行增强。其中，一种方式为，基于网络切片，对不同需求的多个业务提供更低时延，更有目标性，更大的灵活性和更高的可扩展性服务。更具体地说，RAN slicing可以使得，让应用程序提供商参与定制RAN的设计、部署和操作，更好地支持应用程序提供商的业务。
2.小区选择和重选
终端设备在空闲态(RRC_idle态，简称为idle态)下执行小区选择和重选过程中，为了满足idle态下负荷均衡，定义了基于频率优先级的小区选择和重选策略。
小区重选(cell reselection)指终端设备在空闲模式下通过监测邻区和当前小区的信号质量以选择一个最好的小区提供服务信号的过程。当邻区的信号质量及电平满足S准则且满足一定重选判决准则时，终端设备将接入该小区驻留。
在基于切片的小区重选过程中，终端设备需要针对切片对应的支持频点、支持的频点优先级、切片的优先级、支持切片的小区等信息中的至少之一，进行针对切片(slice-specific)的小区重选过程，使得终端设备能够尽快接入支持需求切片的小区。总的来说，终端设备基于切片信息，确定频点的优先级，然后根据相关的小区重选准则，进行测量和能否驻留的决定。可选地，对一个对应支持切片的频点来说，部分小区可能并不支持终端设备需要的切片。
3.终端设备上报(针对SON(Self-Organizing Network，自组织网络)/MDT(Minimization of drive-tests，最小化路测)功能)：终端设备在空闲态记录并且报告已登录测量报告
传统上，为了更加了解移动网络的性能，移动网络建设者或者网络运营商需要驾驶一辆汽车沿着固定的线路来采集下行信号质量/干扰量等一系列反映当前网络性能的测量量。基于采集到的关于网络性能的测量量，网络优化团队继而可以对移动网络设备的部署、信号的强弱、天线角度的设定进行调整，以提高移动网络的性能和用户的满意度。但是，这种方法的弊端是随着移动网络的规模的扩大，路测就会变得更加耗时耗力，不利于移动运营商及时调整网络部署和消耗很大的成本。
基于此，移动网络引入一种叫做最小化路测(MDT)的信号采集方法，它的核心思想是在获取终端设备准许的情况下，使能众多终端设备上报他们的信号采集量。在终端设备的数量足够的前提下，网络可以快速地、非常经济地获取到区域内网络性能相关信息，这种收集某些目标区域的终端设备的网络性能的方式叫做基于管理的MDT(management-based MDT)。此后，MDT也用于帮助网络收集特定终端设备(如该终端用户经常投诉网络性能差)的网络性能相关数据，这种MDT采集方式被称为基于信号的MDT(signaling-based MDT)。MDT配置文件通过5G核心网控制面网元或者网管(Operation Administration and Maintenance，简称OAM)发送给终端设备，终端设备在完成采集并且上报报告给基站后，基站将其发送给独立的MDT数据分析网元，如TCE。
MDT的配置信令必须是在终端设备处于连接态(RRC_connected态，简称为connected态)时由网络 发送给终端设备的。当网络配置的是logged(已记录)MDT，终端设备将在回退到RRC_idle态时记录到的测量量在恢复连接态时上报给网络。
具体流程如图2所示：
步骤21，终端设备接收来自接入网设备的测量配置信息；
步骤22，终端设备在RRC空闲态下完成测量；
步骤23，终端设备进入RRC连接态并指示“已记录的测量可提供”，让网络知道设备有测量数据要上报；
步骤24，接入网设备向终端设备发送UE信息请求；
步骤25，终端设备向接入网设备发送UE信息响应，该UE信息响应中包括上述记录的测量数据；
步骤26，接入网设备向TCE发送MDT记录报告。
当前Logged MDT支持两种测量量记录触发方式，分别是周期性和事件触发性。当触发方式为周期性时，终端设备每隔一段时间就记录测得的无线测量结果(radio measurement results)。当触发方式为事件型时，当配置事件条件满足时，终端设备记录测得的无线测量结果。
