Description

一种数据分析方法、装置及系统
本申请要求于2022年05月06日提交国家知识产权局、申请号为202210490402.9、申请名称为“一种数据分析方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种数据分析方法、装置及系统。
背景技术
5G网络引入了网络数据分析功能(Network Data Analytics Function，NWDAF)网元，它可以接收消费者(consumer)NF网元的订阅请求。然后，NWDAF网元从网络中收集相应的数据，并对这些数据进行处理和分析，得到统计或预测的分析结果。最后，NWDAF网元将分析结果作为移动性分析信息反馈给consumer NF网元。
虽然，NWDAF网元可以向consumer NF网元提供终端的移动性分析信息，但是NWDAF网元向consumer NF网元提供的移动性分析信息不全面，不利于consumer NF网元进行数据处理或者信息决策。
发明内容
本申请实施例提供一种数据分析方法、装置及系统，用以实现数据分析网元向消费者网络功能网元提供终端位置的时间顺序。
本申请实施例提供如下技术方案：
第一方面，本申请实施例提供一种数据分析方法，包括：数据分析网元获取用于指示数据分析网元向第一网元的第一指示信息，其中，第一指示信息用于指示向第一网元提供用于确定终端在第一时间段内所在的一个或多个位置的时间顺序的移动性分析信息。数据分析网元从第二网元处获取终端的移动性相关信息。数据分析网元根据第一指示信息，处理移动性相关信息，得到移动性分析信息。其中，移动性分析信息包括用于确定终端在第一时间段内所在的一个或多个位置的时间顺序的信息。或者，移动性分析信息包括用于确定在第一时间段内包括的任一个子时间段内终端的一个或多个位置的时间顺序的信息。
本申请实施例提供的一种数据分析方法，该方法中通过数据分析网元接收第一指示信息，由于该第一指示信息指示数据分析网元向第一网元提供用于确定终端在第一时间段内所在的一个或多个位置的时间顺序的移动性分析信息，因此为了便于第一网元了解终端在一个时间段(比如第一时间段)内所在的多个位置中各个位置的时间顺序，数据分析网元向第一网元提供的移动性分析信息用于指示终端在第一时间段内所在的一个或多个位置的时间顺序的信息。
可选的，第一指示信息用于指示数据分析网元向第一网元发送终端的移动性分析信息可以指示终端在第一时间段内的多个位置的时间顺序。
在本申请的一个可能的实现方式中，本申请实施例提供的方法还可以包括：数据分析网元向第一网元发送移动性分析信息。
在本申请的一个可能的实现方式中，数据分析网元可以满足上报触发条件的情况下，向第一网元发送移动性分析信息。比如，数据分析网元可以在数据分析网元的负载低于预设负载阈值的情况下，向第一网元发送移动性分析信息，或者数据分析网元可以在第一网元指示的时间段内向第一网元发送移动性分析信息，本申请实施例对此不做限定。
在本申请的一个可能的实现方式中，第一指示信息可以由第一网元向数据分析网元发送，也可以由其他网元向数据分析网元发送，本申请实施例对此不做限定。在由其他网元向数据分析网元发送第一指示信息的情况下，其他网元还可以向数据分析网元提供第一网元的信息。比如第一网元的地址信息或者标识信息。
在本申请的一个可能的实现方式中，本申请实施例提供的方法还包括：数据分析网元接收第二指示信息。其中，第二指示信息用于指示数据分析网元提供终端在每个位置的驻留时间的信息。这样便于根据驻留时间的信息确定终端在各个位置的驻留时间(时长)。
在本申请的一个可能的实现方式中，数据分析网元向所述第一网元发送所述移动性分析信息，还包括：数据分析网元向第一网元发送终端在每个位置的驻留时间的信息。
举例说明，移动性分析信息中还包括用于确定终端在每个位置的驻留时间的信息。该方案可以实现终端在每个位置的驻留时间的信息包含于移动性分析信息中。或者终端在每个位置的驻留时间的信息也可以通过移动性分析信息外的其他信息发送给第一网元，本申请实施例对此不做限定。
在本申请的一个可能的实现方式中，第一时间段包括一个或多个子时间段，所述终端在每个所述子时间段内具有一个或多个位置，所述子时间段对应一个时间信息以及所述子时间段的时长，所述子时间段的时间信息为所述子时间段的起始时间。

在本申请的一个可能的实现方式中，移动性分析信息中包括所述终端在所述第一时间段的各个子时间段内的一个或多个所述位置按照时间递增或递减顺序排序的信息。比如，在第一时间段的一个子时间段内，时间早的位置位于时间晚的位置之前。
在本申请的一个可能的实现方式中，移动性分析信息中包括一个或多个子移动性分析信息，每个子移动性分析信息对应第一时间段中的一个子时间段，其中，该子移动性分析信息包括的该终端在一个子时间段内的多个位置按照时间递增或递减顺序排序。或者，移动性分析信息中包括的终端在一个子时间段或多个子时间段中每个子时 间段内的多个位置的按照时间递增或递减顺序排序。
在本申请的一个可能的实现方式中，每个子移动性分析信息对应第二时间段中的一个时间段的情况下，数据分析网元可以按照每个时间段的先后顺序向第一网元发送每个子移动性分析信息。或者数据分析网元可以确定每个子移动性分析信息的编号，各个子移动性分析信息的编号用于确定各个子移动性分析信息的时间先后顺序。比如，每个子移动性分析信息中可以携带一个用于指示时间段的信息，比如，用于指示时间段的信息可以是该时间段的起始时间和时长，或者用于指示时间段的信息可以是该时间段的起始时间和截止时间。
在本申请的一个可能的实现方式中，第二时间段包括一个或多个时间段，所述移动性分析信息中包括所述终端在每个所述时间段内的一个位置以及第一时间信息，所述第一时间信息为所述终端在所述时间段内开始进入该时间段关联的位置的时间，在时间上相邻的两个子时间段内，所述终端的位置不同。该方案中可以实现一个子时间段只对应终端的一个位置。可以避免出现同一个时间段内终端的多个位置重复的问题。
在本申请的一个可能的实现方式中，移动性分析信息中还包括每个子时间段的时长，子时间段的时长用于反映终端在该子时间段关联的位置的驻留时间的信息。该方案中可以借助每个子时间段的时长反映终端在一个位置的驻留时间，省去了在移动性分析信息中额外添加终端在各个位置的驻留时间的信息。
在本申请的一个可能的实现方式中，时间段的时长小于预设时间长度，比如，时间段的长度可以小于终端在各个位置的驻留时间。
在本申请的一个可能的实现方式中，移动性分析信息中还包括用于确定终端在每个位置的驻留时间的信息。
在本申请的一个可能的实现方式中，数据分析网元从第二网元处获取终端的移动性相关信息，包括：数据分析网元向第二网元发送第二消息。该第二消息用于请求第二网元提供终端在第二时间段内的移动性相关信息。数据分析网元接收来自所述第二网元的所述移动性相关信息，所述移动性相关信息包括所述终端在所述第二时间段内所在的各个位置以及与各个位置关联的时间信息，所述时间信息为进入所述位置的时间。

在本申请的一个可能的实现方式中，数据分析网元向第二网元发送第二消息，还包括：数据分析网元向第二网元发送第三指示信息，其中，第三指示信息用于指示第二网元提供用于确定终端的各个位置的时间顺序的信息。这样可以由第一指示信息指 示由第二网元对终端的各个位置进行排序或者对终端的各个位置添加时间信息。
可选的，第三指示信息可以携带在第二消息中，或者第三指示信息可以携带在除第二消息外的第三消息中，本申请实施例对此不做限定。
在本申请的一个可能的实现方式中，数据分析网元向第二网元发送第二消息，还可以包括：数据分析网元向第二网元发送第四指示信息。第四指示信息用于指示向所述数据分析网元提供所述终端在所述第二时间段内所在的一个或多个位置的驻留时间的信息，相应的，移动性相关信息还包括用于确定所述终端在所述第二时间段内的每个所述位置的驻留时间的信息。
可选的，第四指示信息可以携带在第二消息中，或者第四指示信息可以携带在除第二消息外的消息中，比如第三消息或者第四消息中，本申请实施例对此不做限定。
第二方面，本申请提供一种数据分析方法，包括：第一网元向数据分析网元发送第一指示信息。其中，第一指示信息用于指示向第一网元提供用于确定终端在第一时间段内所在的一个或多个位置的时间顺序的移动性分析信息。第一网元接收来自数据分析网元的移动性分析信息，其中，移动性分析信息包括用于确定终端在第一时间段内所在的一个或多个位置的时间顺序的信息。
可选的，第一时间段可以为已经过去的一个时间段，也可以是将来的一个时间段，本申请实施例对此不做限定。
在本申请的一个可能的实现方式中，本申请实施例提供的方法还包括：第一网元向数据分析网元发送用于指示所述数据分析网元提供终端在每个位置的驻留时间的信息的第二指示信息。这样可以利用有助于数据分析网元根据第二指示信息明确需要向第一网元提供终端在每个位置的驻留时间的信息。
在本申请的一个可能的实现方式中，第一指示信息和第二指示信息可以为同一个指示信息，换言之，即该指示信息既用于指示数据分析网元提供用于确定终端的各个位置的时间顺序的信息，也用于指示数据分析网元提供终端在各个位置的驻留时间的信息。
在本申请的一个可能的实现方式中，第一网元可以以显式指示方式向数据分析网元指示提供用于确定终端的各个位置的时间顺序的信息，比如发送第一指示信息。当然第一网元可以以隐式指示方式向数据分析网元指示提供用于确定终端的各个位置的时间顺序的信息，比如，第一网元发送第二指示信息，而不发送第一指示信息，这样数据分析网元在接收到第二指示信息的情况下，便可以确定既用于指示数据分析网元提供用于确定终端的各个位置的时间顺序的信息，也用于指示数据分析网元提供终端在各个位置的驻留时间的信息。
在本申请的一个可能的实现方式中，第一网元接收来自数据分析网元的移动性分析信息还包括：第一网元接收来自数据分析网元的终端在每个位置的驻留时间的信息。
在本申请的一个可能的实现方式中，移动性分析信息中包括终端在第一时间段的各个子时间段内所在的每个位置的时间信息。时间信息为所述终端在所述子时间段内进入所述位置的时间。任一个位置对应的时间信息用于指示任一个位置在子时间段内的一个或多个位置中的时间顺序。

在本申请的一个可能的实现方式中，子时间段的时长小于预设时间长度。
在本申请的一个可能的实现方式中，移动性分析信息中还包括用于确定终端在每个位置的驻留时间的信息。

如图1所示，图1为本申请实施例提供的一种通信系统的架构示意图，该系统包括：消费者网络功能网元100、数据分析网元200以及一个或多个数据提供网元300。
其中，数据分析网元200用于向消费者网络功能网元100提供终端的移动性分析结果，比如，终端移动过程中，终端在一个时间段内所处的一个或多个位置以及用于确定终端进入每个位置的时间先后顺序的信息。

作为一种示例，一个或多个数据提供网元300可以包括应用网元、移动性管理网元或者网管网元。
以如图1所示的系统应用于如图2a或图2b所示的5G网络架构为例，则上述消费者网络功能网元100可以为如图2a或图2b所示的5G核心网(5G core，5GC)中的网元和网管网元，比如OAM。比如，5G核心网(5G core，5GC)中的网元可以为以下网元中的任一个：策略控制功能(policy control function，PCF)网元，网络切片 选择功能(network slice selection function，NSSF)网元，接入与移动性管理功能(Access and Mobility Management Function，AMF网元)，会话管理功能(session management function，SMF)网元，网络能力开放功能(network exposure function，NEF)网元,应用功能(application function，AF)网元，NWDAF网元，数据收集协调功能(Data Collection Coordination Function，DCCF)网元)。应用网元可以为AF网元，移动性管理网元可以为AMF网元，网管网元可以为OAM网元。在5G网络中，本申请实施例中数据分析网元可以为5GC中的网络数据分析功能(network data analytics function，NWDAF)网元，也可以是网管的管理数据分析功能(Management Data Analytics Function，MDAF)网元，甚至可以是无线接入网(Radio Access Network，RAN)侧的数据分析网元。

需要说明的是，图2a和图2b的(R)AN设备、AMF网元、SMF网元、UDM网元、UPF网元和PCF网元等仅是一个名字，名字对设备本身不构成限定。在5G网络以及未来其它的网络中，(R)AN设备、AMF网元、SMF网元、UDM网元、UPF网元和PCF网元所对应的网元或实体也可以是其他的名字，本申请实施例对此不作具体限定。例如，该UDM网元还有可能被替换为用户归属服务器(home subscriber server， HSS)或者用户签约数据库(user subscription database，USD)或者数据库实体，等等，在此进行统一说明，后续不再赘述。
终端，允许用户接入网络服务的设备。3GPP标准中，终端和网络间的接口是无线接口。
终端(terminal)可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备；还可以包括用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop，WLL)台、机器类型通信(machine type communication，MTC)终端、用户设备(user equipment，UE)，移动台(mobile station，MS)，终端设备(terminal device)或者中继用户设备等。其中，中继用户设备例如可以是5G家庭网关(residential gateway，RG)。为方便描述，本申请中，上面提到的设备统称为终端。
应理解，本申请实施例中的终端还可以为物联网终端设备、港口、智能工厂、铁路交通、物流、无人机、无人驾驶汽车等多种垂直行业应用领域中的终端。例如：移动机器人(mobile robot)、自动导引车(automated guided vehicle，AGV)，无人驾驶汽车，列车上的控制设备和传感器、工厂中部署的控制设备和传感器(sensor)等。
作为示例，在本申请实施例中，该终端还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。该终端还可以为应用于工厂的传感器设备。
NWDAF网元：网络数据分析功能。其具备数据收集、训练、分析、推理功能，可以用于收集来自网络网元、第三方业务服务器、终端设备或网管系统中的相关数据，基于相关数据做分析训练，并向网络网元、第三方业务服务器、终端设备或网管系统提供数据分析结果，该数据分析结果可协助网络选择业务的服务质量参数，或协助网络执行流量路由，或协助网络选择背景数据传输策略等。
网络功能网元(Network Function，NF)，如PCF网元，AMF网元，SMF网元，NEF网元，AF，网元，NWDAF网元等。
AMF网元，主要负责用户的接入和移动性等管理，包括用户注册、可达性、移动性管理、N1/N2接口信令传输、接入鉴权和授权等。
AF网元，传递应用侧对网络侧的需求，例如，QoS需求或用户状态事件订阅等。AF可以是第三方功能实体，也可以是运营商部署的应用服务器。
OAM：运营、监管和管理，简称网管。主要完成日常网络和业务的分析、预测、 规划和配置工作，以及对网络及其业务的测试和故障管理等。OAM可以和RAN交互，获取RAN侧由RAN测量的或者UE测量上报的UE位置。
NWDAF网元支持consumer NF网元请求/订阅终端的移动性分析结果。在接收到consumer NF网元请求/订阅终端的移动性分析结果的后，为了能够推导得出相应的分析结果，NWDAF网元需要从OAM网元、AMF网元以及AF网元处收集相应的数据。具体的，NWDAF网元可以从OAM网元获取终端的位置，OAM网元处的终端的位置包含在最小化路测(Minimization of Drive Tests，MDT)数据中，MDT数据是终端通过基站上报给OAM网元的测量报告数据和/或基站自身测量的每终端的数据然后上报给OAM网元的测量报告数据，其中包含终端的位置。此外，NWDAF网元可以从AMF网元获取终端的移动性相关的网络数据，如终端的位置、终端的位置趋势、终端的接入行为趋势等，具体内容如表1所示。
表1 从AMF网元处收集的终端的移动性信息
示例性的，本申请实施例中的终端的标识可以为以下一个或者多个：网际协议地址(internet protocol，IP)、签约永久标识(subscription permanent identifier，SUPI)、永久设备标识(permanent equipment identifier，PEI)、通用公共签约标识(generic public subscription identifier，GPSI)、国际移动用户标识符(international mobile subscriber identifier，IMSI)、国际移动设备标识(international mobile equipment identity，IMEI)、IP地址和移动台国际综合业务数字网络号码(mobile station international integrated service digital network number，MSISDN)。下述实施例中但凡涉及到终端的标识均可以参考此处的描述，后续不再赘述。
NWDAF网元还可以从AF网元(可能是核心网内部的AF网元或者第三方AF网元)获取终端的移动性相关的业务数据，具体如表2所示。
表2 从AF网元收集的终端的移动性相关业务数据
根据上述信息，NWDAF网元可以进行历史数据分析，得到终端的移动性的统计分析结果，如表3所示：
表3 终端移动性的统计分析结果
或者，NWDAF网元可以根据历史数据训练人工智能(Artificial Intelligence，AI)模型，并利用该AI模型预测未来某个时间段内终端的移动性信息，如表4所示：
表4 终端的移动性的预测分析结果
其中，分析结果中的时隙应当按时间先后顺序提供(不同时隙有可能重叠)。如果分析结果是针对一组终端(即提供终端的group ID)，则在同一个时隙内，这些终端可能位于不同的位置区域(如TA/cell标识的位置区域)，位于不同位置区域的终端 的数量的比例可能也不同，在分析结果中应当按照终端的数量比例从大到小列出这些位置区域(由于分析结果最大条目数的限制，也可能不会列出UE数量比例非常小的位置区域)。
NWDAF网元得到的终端的移动性分析结果(也可以称之为：移动性分析信息)，可以是统计或预测到的同一个时隙(时间段)内多个终端的位置，或者一个终端在不同时间的多个位置，如表5所示。但是，目前数据分析网元得到的终端的移动性分析结果并没有定义同一个时隙内多个位置的先后顺序。而在某些场景下，consumer NF网元在进行数据处理或者信息决策又需要从NWDAF网元获取终端的多个位置的时间先后顺序。例如，向在道路上行驶的车辆发送交通堵塞或交通事故警告信息时，需要根据位置方向信息来确定车辆是位于道路的上行车道还是下行车道，然后才能向车辆发送正确的通知或警告信息。
表5 相关技术中NWDAF网元确定的终端的移动性分析结果的内容
表5以表格的形式示出了NWDAF网元提供的终端的移动性分析结果，从表5中可以看出虽然移动性分析结果包括了终端在一个时隙(比如，时隙1，即Time slot start1和Duration 1所确定的时隙)内终端所在的多个位置的位置。比如位置11指示终端位于小区1和位置12指示终端位于小区2。但是对于消费者网络功能网元而言，在得到如表5所示的终端的移动性分析结果的情况下，可以获知在时隙1内终端位于小区1和小区2，但是无法判断终端所在的小区1和小区2时间先后顺序，即终端是先处于小区1还是先处于小区2，即无法判断终端是从小区1移动至小区2还是从小区2移动至小区1。
基于此，本申请实施例提供一种数据分析方法，用于实现数据分析网元向消费者网络功能网元提供的终端的移动性分析信息中可以指示终端在不同位置的时间先后顺序，辅助consumer NF网元进行数据处理或者信息决策。
在本申请实施例中，一种数据分析方法的执行主体的具体结构，本申请实施例并未特别限定，只要可以通过运行记录有本申请实施例的一种数据分析方法的代码的程序，以根据本申请实施例的一种数据分析方法进行通信即可。例如，本申请实施例提供的一种数据分析方法的执行主体可以是数据分析网元中能够调用程序并执行程序的功能模块，或者为应用于数据分析网元中的通信装置，例如，芯片、芯片系统、集成电路等等。这些芯片、芯片系统、集成电路可以设置于数据分析网元的内部，也可以相对于数据分析网元独立，本申请实施例不做限制。本申请实施例提供的一种数据分 析方法的执行主体可以是第一网元中能够调用程序并执行程序的功能模块，或者为应用于第一网元中的通信装置，例如，芯片、芯片系统、集成电路等等，这些芯片、芯片系统、集成电路可以设置于第一网元内部，也可以相对于第一网元独立，本申请实施例不做限制。
如图3所示，图3为本申请实施例提供的一种数据分析方法的流程示意图，该方法包括：
步骤301、第一网元向数据分析网元发送第一指示信息。相应的，数据分析网元接收来自第一网元的第一指示信息。其中，第一指示信息用于指示数据分析网元发送终端的移动性分析信息。
具体的，第一指示信息用于指示数据分析网元向第一网元发送用于指示终端的位置先后顺序的移动性分析信息，换言之，第一指示信息用于指示数据分析网元向第一网元发送的移动性分析信息要包括用于确定终端的多个位置的先后顺序的信息。
结合图1所示，第一网元可以为如图1所示的消费者网络功能网元100。数据分析网元可以是NWDAF网元。
可选的，第一指示信息携带在第一消息中，第一消息用于请求数据分析网元提供终端的移动性分析信息。或者第一指示信息携带在第一消息外的其他消息中，比如，第一网元先向数据分析网元发送第一消息，之后再发送第一指示信息。或者第一指示信息和第一消息可以携带在同一个消息(比如，数据订阅消息或者数据请求消息)中发送给数据分析网元，本申请实施例对此不做限定。第一消息用于请求数据分析网元提供终端的移动性分析信息。或者用于向数据分析网元订阅终端的移动性分析信息，本申请实施例对此不做限定。
如图3所示的实施例中，以第一指示信息由第一网元向数据分析网元提供为例，当然，在实际过程中第一指示信息也可以由除第一网元外的其他网元发送给数据分析网元，该其他网元向数据分析网元发送第一指示信息时，还可以提供第一网元的信息，以指示数据分析网元向第一网元发送得到的移动性分析信息。
可选的，第一消息中还可以携带有用于确定收集对象(比如，终端)的信息。比如，第一消息中还可以携带一个或多个终端的标识信息、目标区域的信息、网络切片的信息、应用的信息中的一个或多个。
比如，第一消息中携带一个或多个终端的标识信息，表示第一网元希望数据分析网元提供一个或多个终端的标识信息所标识的特定终端的移动性分析信息，即每个终端在不同时间的位置以及一个终端在不同时间的多个位置的先后顺序。比如，第一消息中携带终端0的标识信息，则表示第一网元希望数据分析网元提供终端0的移动性分析信息。
比如，第一消息中还可以携带目标区域(比如，TA或者Cell)的信息，这样表示第一网元希望数据分析网元提供位于该目标区域中的一个或多个终端的移动性分析信息。比如，第一消息中携带目标区域的信息以及一个或多个终端的标识信息，表示第一网元希望数据分析网元提供位于该目标区域中且包括上述一个或多个终端的标识信息的终端的移动性分析信息。例如，目标区域为小区1，一个或多个终端的标识信息包括终端1～终端4，而小区1中具有终端0～终端100，则第一网元可以通过目标区域的信息 以及终端1～终端4的标识信息，向数据分析网元请求位于小区1内的终端1～终端4的移动性分析信息。
可选的，第一消息中还可以包括分析目标时间窗(Analytics target period)，以表示第一网元希望获取终端在分析目标时间窗内的移动性分析信息。比如，该分析目标时间窗可以是过去的某个时间段，也可以是未来的某个时间段(表示第一网元想要获取预测的终端的移动性分析结果)。比如，分析目标时间窗可以是相对于现在已经过去的时间段，比如，假如现在是11点，分析目标时间窗可以是8点～9点的时间段，也可以是相对于现在而言，将来的某一段时间。假如现在是11点，分析目标时间窗可以是12点～13点之间的时间段。
通过提供分析目标时间窗可以使得数据分析网元确定为终端确定的移动性分析信息是对终端在过去一段时间内的各个位置进行统计的信息(即终端的移动性统计信息)还是对未来一段时间段内终端的各个位置进行预测的信息(即终端的移动性预测信息)。
可选的，第一消息中还可以携带预测指示或者统计指示，其中，统计指示用于指示数据分析网元对终端在过去一段时间内的移动性进行统计。预测指示用于指示数据分析网元对未来一段时间段内终端的移动性进行预测。
可以理解的是，在第一消息中未携带分析目标时间窗，而携带了预测指示或者统计指示的情况下，数据分析网元可以自行决定将当前时刻之前的一段时间作为分析目标时间窗，也可以选择将当前时刻之后的一段时间作为分析目标时间窗，本申请实施例对此不做限定。
可选的，第一消息中包括分析目标时间窗的情况下，第一消息可以包括预测指示或者统计指示，也可以不包括，本申请实施例对此不做限定。
可选的，第一消息中还可以包括一个或多个时间信息(比如时隙)，不同时间信息的长度可以相同，也可以不相同，比如，时间信息的长度可以为3秒或者5秒。通过提供一个或多个时间信息便于数据分析网元确定各个时间信息内终端的移动时的位置顺序。比如，时间信息长度为3秒，则表示希望数据分析网元提供终端在3秒内移动的各个位置的时间先后顺序。
举例说明，第一消息中携带终端0的标识信息以及已过去的8点～10点之间的时间段，则表示第一网元希望数据分析网元提供终端0在已过去的8点～10点之间的时间段各个位置的先后顺序。
举例说明，第一消息中携带感兴趣区域(area of interest，AoI)的信息以及已过去的8点～10点之间的时间段，则表示第一网元希望数据分析网元提供AoI的信息指示的感兴趣区域内各个终端在已过去的8点～10点之间的时间段内的各个位置的时间先后顺序。
举例说明，第一消息中携带AoI的信息以及预测指示，则表示第一网元希望数据分析网元预测在AoI的信息指示的感兴趣区域内各个终端在一段时间内移动的各个位置的先后顺序。
步骤302、数据分析网元从第二网元处获取终端的移动性相关信息。其中，移动性相关信息中至少包括终端在第二时间段内所在的一个或多个位置中每个位置关联的时间信息。
作为一种示例，第二网元可以为AMF网元或者AF网元或者OAM网元中的任一个或多个。AMF网元或者AF网元或者OAM网元向数据分析网元提供的移动性相关信息如表1～表3所示，此处不再赘述。
步骤303、数据分析网元根据第一指示信息，处理移动性相关信息，得到移动性分析信息。其中，移动性分析信息包括用于确定终端在第一时间段内所在的一个或多个位置的时间先后顺序的信息。
可选的，移动性分析信息中还可以包括终端在第一时间段内所在的一个或多个位置的位置。
可以理解的是，在数据分析网元获取到分析目标时间窗的情况下，第一时间段可以为分析目标时间窗，也可以是分析目标时间窗中的一个时间段。在数据分析网元未获取到分析目标时间窗的情况下，如果数据分析网元确定需要获取终端的移动性预测信息，则第一时间段可以为数据分析网元自行确定的将来的一段时间。在数据分析网元未获取到分析目标时间窗的情况下，如果数据分析网元确定需要获取终端的移动性统计信息，则第一时间段可以为数据分析网元自行确定的已经过去的一段时间。
可选的，本申请实施例中的移动性相关信息可以是终端在第一时间段内的移动性相关信息，那么在数据分析网元确定提供的移动性分析信息用于预测终端在未来一段时间内移动的各个位置的先后顺序的情况下，第一时间段为将来的一个时间段，比如，这时第一时间段位于第二时间段之后，第二时间段为已过去的一段时间。在数据分析网元确定统计终端在过去一段时间内移动的各个位置的先后顺序的情况下，第一时间段可以为第二时间段，也可以为第二时间段中的部分时间段，或者第一时间段可以包括第二时间段，本申请实施例对此不做限定。
步骤304、数据分析网元向第一网元发送移动性分析信息。相应的，第一网元接收来自数据分析网元的移动性分析信息。
本申请实施例提供的一种数据分析方法，该方法中通过数据分析网元获取第一指示信息，由于该第一指示信息指示数据分析网元提供终端的移动性分析信息，因此为了便于第一网元了解终端在一个时间段(比如第二时间段)内所在的多个位置中各个位置的时间先后顺序，以确定终端的移动方向，数据分析网元向第一网元提供的移动性分析信息用于指示终端在第二时间段内所在的一个或多个位置的时间先后顺序的信息。
为了确定终端在各个位置的驻留时间，在本申请的一个可能的实施例中，本申请实施例提供的方法还包括：第一网元向数据分析网元发送第二指示信息。相应的，数据分析网元接收来自第一网元的第二指示信息。其中，第二指示信息用于指示所述数据分析网元上报所述终端在每个位置的驻留时间的信息。
同上，数据分析网元也可以从其他网元处获取到第二指示信息。
在本申请的一个可能的实现方式中，即使数据分析网元未接收到第二指示信息，数据分析网元也可以自行确定在移动性分析信息中包括终端在每个位置的驻留时间的信息。
在本申请的一个可能的实现方式中，在数据分析网元确定要提供终端在各个位置的驻留时间的信息的情况下，移动性分析信息中还包括用于确定终端在每个位置的驻 留时间的信息。用于确定终端在每个位置的驻留时间的信息可以是各个位置所关联的驻留时间的信息，除了为各个位置关联驻留时间的信息外，还可以利用时间上相邻的两个位置关联的时间信息反映终端在各个位置的驻留时间，或者在一个子时间段对应一个终端的位置的情况下可以由该子时间段的时长反映该终端的在该子时间段内的位置的驻留时间的信息。
这样对于第一网元而言，其便可以根据时间上相邻的两个位置所关联的时间信息，以及各位置所属的时间段的时长，得到终端在各个位置的驻留时间的信息。
比如说：终端在时间段a内于2022年5月1日13:12:10进入位置1，终端在时间段a内于2022年5月1日13:12:15进入位置2，这样便可以确定终端在位置1的驻留时间的信息为5s。终端在与时间段a相邻的时间段b内于2022年5月1日13:12:19进入位置3，则可以确定终端在位置2的驻留时间的信息为4s。假如时间段a的时长为9s，则在根据位置1的时间和位置2的时间之间的时间差得到位置1的驻留时间的信息后，便可以根据时间段a的时长9s，得到终端在时间段a内在位置2的驻留时间的信息为4s。
比如说，数据分析网元接收到来自第一网元的第二指示信息，则数据分析网元便可以确定要提供终端在各个位置的驻留时间的信息。
下述将从不同方面描述移动性分析信息的内容。
方式(1)、移动性分析信息包括的各个位置均关联一个时间信息(比如时间戳)。
在本申请的一个可能的实现方式中，移动性分析信息中包括终端在第一时间段的各个子时间段内所在的每个位置的时间信息，即移动性分析信息中包括与终端在第一时间段的各个子时间段内所在的每个位置关联的时间信息。可以理解的是，在第一时间段包括一个子时间段时，该子时间段即为第一时间段。
其中，时间信息为在一个子时间段内终端进入位置的时间，多个位置的时间信息用于确定终端在多个位置之间移动的先后顺序。
通常情况下，在一个子时间段内终端可能一直驻留在一个位置，对于移动性终端，其在一个子时间段内可能处于多个位置，因此在同一个子时间段内该终端的多个位置中每个位置均可以关联一个时间信息。
可选的，第一时间段包括多个子时间段的情况下，各个子时间段的时长可以相同，也可以不相同，本申请实施例对此不做限定。在第一时间段包括一个子时间段的情况下，第一时间段即为该子时间段。比如说，第一时间段包括10秒，假设终端在该10秒内分别处于8个位置，则移动性分析信息中可以包括至少8个位置关联的时间信息。这是由于可能在第二网元获取终端的移动性相关信息时，假设AMF网元每隔2秒采集一次终端的位置，在相邻的2个采集时间内该终端的位置可能未发生变化，则终端在同一个位置可能对应2个或2个以上的时间信息。
在本申请的一个可能的实现中，数据分析网元在确定移动性分析信息时，可以将第一时间段划分为一个或多个子时间段，然后确定各个子时间段内终端的所处的每个位置关联的时间信息。即，移动性分析信息包括一个或多个子移动性信息，每个子移动性信息包括终端在第一时间段的一个时间段所处的每个位置关联的时间信息。
可以理解的是，假设数据分析网元从AMF网元处收集到如表1所示的内容，其包括终端在不同时间的位置(即每个位置关联一个时间信息)，则数据分析网元可以根 据AMF网元提供的终端在不同时间的位置，得到如表6所示的该终端的移动性分析信息。
如下表6所示，可以在终端的移动性分析信息中为每个终端的位置添加一个时间戳(timestamp)，该时间戳可以由AMF网元/AF网元/OAM网元返回的终端的移动性相关信息中获得：
表6
举例说明，从表6中可以看出终端从2022-04-24 11:37:18起的3秒内在小区1和小区2之间移动，且终端在2022-04-24 11:37:18进入小区1，在2022-04-24 11:37:19进入小区2，这样对于第一网元而言其可以根据终端进入每个位置的时间信息，得到终端的多个位置的时间先后顺序。对于不同终端而言，第一网元可以根据各个终端在每个位置的时间信息，确定两个终端在同一位置的先后顺序。
可选的，在第一消息中携带时间信息(比如，表1中的Time slot start1和Duration 1指示的时隙，该时隙的长度为3秒，或者表2中Time slot start2和Duration 2指示的时隙，该时隙的长度为5秒)的情况下，每个子移动性分析信息关联一个时间信息。比如，子移动性分析信息1的内容包括表1中Time slot start1、Duration 1、UE location11和UE location11关联的时间戳11、UE location12和UE location12关联的时间戳12。比如，子移动性分析信息2的内容包括表1中Time slot start2、Duration 2、UE location21和UE location21关联的时间戳21、UE location22和UE location22关联的时间戳22，以及UE location23和UE location23关联的时间戳23。
可以理解的是，结合表6，第一时间段可以包括多个子时间段，比如，Time slot start1和Duration 1指示的时隙可以作为第一时间段的一个子时间段，而Time slot start2和 Duration 2指示的时隙可以作为第一时间段的另一个子时间段。
可选的，移动性分析信息中还可以包括终端在各个位置的驻留时间的信息。比如，如表7所示，为本申请实施例提供的携带驻留时间的信息的移动性分析信息。
表7 携带驻留时间的信息的移动性分析信息
举例说明，从表7中可以看出UE从2022-04-24 11:37:18起的3秒钟之内在小区(cell)1和小区(cell)2之间移动，且UE在2022-04-24 11:37:18进入小区1，在小区1的驻留时间为1s，在2022-04-24 11:37:19进入小区2，在小区2的驻留时间为2s。
在本申请的一个可能的实现方式中，无论第一网元是否提供第二指示信息，数据分析网元均可以在终端的移动性分析信息中包括终端在各个位置的驻留时间的信息。
在本申请的另一个可能的实现方式中，在第一网元向数据分析网元提供第二指示信息的情况下，数据分析网元在终端的移动性分析信息中包括终端在各个位置的驻留时间的信息。
可以理解的是，数据分析网元除了可以将移动性分析信息处理成表格的形式，比如表6～表12的形式外，以表6的内容为例，移动性分析信息也可以采用如下方式：{(Time slot start1，2022-04-24 11:37:18)、(Duration 1＝3s)、(UE location11＝小区1，时间戳＝2022-04-24 11:37:18)、(UE location12＝小区2，时间戳＝2022-04-2411:37:19)}、{(Time slot start2，2022-04-24 11:37:21)、(Duration 2＝5s)、(UE location21＝小区3，时间戳＝2022-04-24 11:37:21)、(UE location22＝小区4，时间戳 ＝2022-04-24 11:37:23)、(UE location23＝小区5，时间戳＝2022-04-24 11:37:24)}。
举例说明，对于表7而言，以一个子时间段为例，则移动性分析信息的内容如下：{(Time slot start1，2022-04-24 11:37:18)、(Duration 1＝3s)、(UE location11＝小区1，时间戳＝2022-04-24 11:37:18、residence time11＝1s)、(UE location12＝小区2，时间戳＝2022-04-24 11:37:19、residence time12＝2s)}。
方式(2)、移动性分析信息中包括的终端在不同时间的位置按照预设时间顺序排序。
在方式(2)中，移动性分析信息中包括终端在第一时间段的各个子时间段内按照时间先后顺序排序每个位置的位置。换言之，在方式(2)中，数据分析网元在从第一网元处得到终端的各个位置以及各个位置关联的时间信息后，便可以根据各个位置关联的时间信息，对终端在第一时间段的全部位置按照时间先后顺序进行排序，或者对第一时间段内的任一个子时间段内的全部位置按照时间递增或递减顺序进行排序。可以理解的是，倘若终端在不同时间所在的位置相同，则该排序中可以包括如下结果：位置1、位置2以及位置1，或者位置1，位置1，位置2。在时间上相邻的两个或多个位置相同的情况下，数据分析网元在进行位置排序时，可以只包括时间最早的位置。
在本申请的一个可能的实现中，数据分析网元在确定移动性分析信息时，可以将第一时间段划分为一个或多个子时间段，然后确定各个子时间段内终端的所处的每个位置关联的时间信息。即，移动性分析信息中包括一个或多个子移动性分析信息，每个子移动性分析信息包括按照时间先后顺序排序的终端在第一时间段的一个子时间段内所处的每个位置。
举例说明，数据分析网元在从第二网元处得到终端在各个位置的时间信息之后，便可以根据终端在各个位置的时间信息对终端在同一个子时间段内的多个位置按照时间顺序进行排序，以得到终端的移动性分析信息，如表8所示：
表8 移动性分析信息中包括的多个位置按照时间顺序排序
举例说明，从表8中可以看出终端从2022-04-24 11:37:18起的3秒之内在小区(cell)1和小区(cell)2之间移动，由于小区1的位置位于小区2的位置之前，则表示终端先位于小区1之后由小区1移动至小区2。终端在2022-04-24 11:37:21起的5秒之内在小区(cell)3～小区(cell)5之间移动，且终端先位于小区3之后由小区3移动至小区4，再由小区4移动至小区5。
可选的，如表8所示的移动性分析信息中还可以携带各个位置的编号。比如，小区1的位置编号为1，小区2的位置编号为2。
可以理解的是，数据分析网元可以按照时间顺序逐渐递增或递减的顺序对同一个时隙内的多个位置进行排序，本申请实施例对此不做限定。具体的，为了便于第一网元了解排序后终端在同一个时隙内移动的各个位置的时间先后顺序，至于如何对各个位置进行排序的方式可以由第一网元和数据分析网元协商或者由第一网元向数据分析网元指示，比如，第一网元指示数据分析网元将终端在同一个时隙内最早进入的位置排在首位(比如，小区1)，而将终端在同一个时隙内最晚进入的位置排在末尾(比如，小区2)。
或者在数据分析网元向第一网元提供同一个子时间段内多个位置的排序结果的情况下，数据分析网元还可以向第一网元指示该排序结果是按照由时间由早到晚的顺序，还是时间由晚到早的顺序。
在本申请的一个可能的实现方式中，无论第一网元是否提供第二指示信息，数据分析网元均可以在终端的移动性分析信息中包括终端在各个位置的驻留时间的信息。
在本申请的另一个可能的实现方式中，在第一网元向数据分析网元提供第二指示信息的情况下，数据分析网元在终端的移动性分析信息中包括终端在各个位置的驻留时间的信息。
举例说明，如表9所示，表9示出了移动性分析信息中包括的按照时间先后顺序排序的各个位置所关联的驻留时间的信息。
表9
从表9中可以看出终端在小区1和小区2之间的移动顺序为：从小区1移动至小 区2，小区1关联的residence time11为1s，则表示终端在小区1的驻留时间为1s。小区2关联的residence time11为2s，则表示终端在小区2的驻留时间为2s。
方式(3)、每个时隙(一个子时间段)内只包括一个终端的位置。
在方式(3)中，第一时间段包括一个或多个子时间段，移动性分析信息中包括终端在每个子时间段内一个位置以及第一时间信息。其中，第一时间信息为在子时间段内终端开始进入该子时间段内的一个位置的时间。在时间上相邻的两个子时间段内终端的位置不同，如表10所示，表10中的第一时间段包括子时间段1和子时间段2，其中，子时间段1为Time slot start1和Duration 1确定的时间段。子时间段2为Time slot start2和Duration2确定的时间段。其中，子时间段1内包括终端的在小区1的位置。子时间段2内包括终端的在小区2的位置。
表10
举例说明，移动性分析信息中包括一个或多个子移动性分析信息，每个子移动性分析信息包括一个子时间段内终端的一个位置以及第一时间信息。时间上相邻的两个子移动性分析信息所包括的位置不同。比如，表10中所示的，移动性分析信息包括2个子移动性分析信息。其中，一个子移动性分析信息包括的第一时间信息为Time slot start1，位置为小区1。另一个子移动性分析信息包括的第一时间信息为Time slot start2，位置为小区2。
在本申请的一个可能的实现方式中，移动性分析信息还包括第一时间段包括的各个子时间段的时长，任一子时间段的时长用于反映终端在位置所指示的位置的驻留时间。比如，子时间段可以是表10中的duration1或duration2。可以理解的是，第一时间段的时长由duration1和duration2确定。上述第一时间信息可以是表10中的time slot start1或time slot start2。
上述方案中利用子时间段的时长指示反映终端在位置所指示的位置的驻留时间，可以省去在移动性分析信息中增加额外的驻留时间的信息，降低了移动性分析信息的大小。
对比表10和表6～表9中的任一个表，可以看出表10中的参数”UE location(1..max)”中只包含一个终端的位置，即UE location11，并且”time slot start”用于表示进入该位置的时间。“duration”用于表示终端在该位置的驻留时间。而表6～表9中的任一个表中的参数”UE location(1..max)”中可以包含一个终端的位置，也可以终端的多个位置，即UE location11和UE location12。
方式(1)或方式(2)中，随着终端的移动，该终端可能在同一个子时间段内具有多个位置，比如在子时间段内的时间1，终端处于位置1，但是在子时间段内的时间2，终端处于位置。但是，同一个子时间段内可能包括多个相同的位置，这时由于终端 移动速度比较慢或者终端停止移动，但是AMF网元或者AF网元或者OAM网元还是会根据设定的采集周期，在某个子时间段中每隔一段时间对采集终端的位置。因此，这样就会出现同一个子时间段中连续多个相同的位置，如果将终端在多个相同位置的时间信息均包括在移动性分析信息中，便会多出很多冗余信息，而采用方式(3)就可以规避这种信息冗余的问题，每个子时间段中仅包含一个终端的位置，并将子时间段开始时间定义为终端进入该位置的时间，子时间段的长度定义为终端在该位置的驻留时间。
方式(4)、移动性分析信息中携带的子时间段的时长设置的尽可能小，如下表11所示，比如，子时间段的时长小于或等于预设时间长度，比如1ms或者0.5ms。
表11
表11中由于每个时隙只存在终端的一个位置，因此，表11中的“time slot start”用于表示终端进入该位置的时间，“duration”可以设置为一个极短的时间，比如1ms/1ns。这样做的目的是：在一段极短的时隙内，终端的位置通常不会发生太大变化，因此也就不会出现方式(1)～方式(2)中同一个时隙存在终端的多个位置的情况，终端的位置的时间先后顺序可以由不同时隙的开始时间来标识。
如果数据分析网元还接收到的第二指示信息，则如表12所示，移动性分析信息中还可以包括每个位置关联的驻留时间(residence time)信息。该驻留时间的信息可以通过按照时间递增或递减排序后不同位置之间的时间戳做差得到：
表12
在本申请的一个可能的实现方式中，数据分析网元在向第二网元请求终端的移动性相关信息时可以不携带第一指示信息，这样第二网元向数据分析网元虽然可以提供终端在各个位置的时间信息，但是通常所提供的终端在各个位置的时间信息可能并未 按照时间先后顺序进行排序，在这种情况下，数据分析网元从第二网元处获取到终端在各个位置的时间信息后，便可以对终端在各个位置的时间信息按照时间段进行划分，以得到终端在各个时间段内各个位置的时间信息，具体如表6～表12所示的内容。比如，如以第二网元为AMF网元为例，AMF网元向数据分析网元提供的终端的移动性相关信息可以如表13所示：
表13 从AMF网元收集到的终端的移动性相关信息
可以理解的是，表13中将终端在一个时间段内的全部位置放在一个表格中为例，当然实际过程中，AMF网元向数据分析网元也可以提供多个移动性相关信息，每个移动性相关信息中包括终端的一个位置以及终端进入该位置的时间信息。
这样对于数据分析网元而言，其可以根据预设规则(比如，时隙的时长)处理表13，得到如表6～表12中的任一个表格所反映的移动性分析信息。
比如，数据分析网元可以将2022-04-24 11:37:18～2022-04-24 11:37:24看作是第一时间段，将该第一时间段拆分为2个子时间段，即2022-04-24 11:37:18～2022-04-2411:37:19为一个子时间段1，2022-04-24 11:37:21～2022-04-24 11:37:24为一个子时间段2。然后，数据分析网元可以将子时间段1内该终端的UE location11和UE location12分别添加时间戳，以及将子时间段2内的终端的UE location21～UE location23分别添加时间戳，以及添加子时间段1和子时间段2的开始时间和时长，以得到如表6所示的移动性分析信息。可选的，数据分析网元还可以根据表13中时间上相邻的2个位置的时间戳的差值，确定终端在各个位置的驻留时间，然后为各个位置关联驻留时间，以得到如表7所示的内容。
当然，数据分析网元也可以指示第二网元在收集到终端的移动性相关信息时，对终端的移动性相关信息进行整理，然后将整理后的信息发送给数据分析网元，在这种 情况下，上述步骤302可以通过以下方式实现：数据分析网元向所述第二网元发送第二消息。第二消息用于请求所述第二网元提供所述终端在第二时间段的移动性相关信息。数据分析网元接收来自所述第二网元的所述移动性相关信息，所述移动性相关信息包括所述终端在所述第二时间段内所在的各个位置以及与各个位置关联的时间信息，所述时间信息为进入所述位置的时间。
在本申请的一个可能的实现方式中，数据分析网元也可以和第二网元协商由数据分析网元还是第二网元提供用于确定终端在各个位置的时间先后顺序的信息。比如，二者协商由第二网元提供用于确定终端在各个位置的时间先后顺序的信息，则数据分析网元便可以省去向第二网元发送第二指示信息的过程。
在本申请的一个可能的实现方式中，第二消息中携带第三指示信息，第三指示信息用于指示向数据分析网元提供用于确定终端在第二时间段内所在的一个或多个位置的时间顺序的移动性相关信息。相应的，第二网元提供的移动性相关信息还包括终端在第二时间段内的多个位置按照时间信息递增或递减顺序排序的信息，如表14所示。或者，移动性相关信息还包括终端在第二时间段的各个子时间段内的一个位置以及第二时间信息，如表15所示。其中，第二时间信息为终端在子时间段内进入该子时间段关联的位置的时间，在时间上相邻的两个子时间段内，终端的位置不同。可选的，第二时间段包括第一时间段，此处不再赘述。
表14 AMF网元根据第三指示信息提供的移动性相关信息的内容
可选的，AMF网元向数据分析网元提供的移动性相关信息还包括终端在第二时间段内的多个位置按照时间递增或递减顺序排序的信息时，该移动性相关信息可选的还可以包括：终端在每个位置的驻留时间。
表15 AMF网元根据第三指示信息提供的移动性相关信息的内容

表15示出了移动性相关信息还包括终端在第二时间段的各个子时间段(比如子时间段1和子时间段2)内的一个位置以及第二时间信息。比如，第二时间信息可以为2022-04-24 11:37:19或者2022-04-24 11:37:18。
在本申请的一个可能的实现中，第二时间段为过去的一段时间，而第一时间段为将来的一段时间。在这种情况下，数据分析网元可以根据终端在第二时间段内的移动性相关信息预测在第一时间段包括的各个子时间段内终端的各个位置的时间顺序，以得到移动性分析信息。
在本申请的一个可能的实现中，第二消息中还携带第四指示信息，所述第四指示信息用于指示向所述数据分析网元提供所述终端在所述第二时间段内所在的一个或多个位置的驻留时间的信息；移动性相关信息还包括用于确定所述终端在所述第二时间段内的每个所述位置的驻留时间的信息。
在数据分析网元向第二网元提供第三指示信息的情况下，第二网元向数据分析网元所反馈的移动性相关信息的内容可以如表13～表15所示，在数据分析网元确定是推导UE移动性的统计结果的情况下，上述步骤303可以通过以下方式实现：数据分析网元便可以对移动性相关信息进行整理即可得到移动性分析信息，比如将表13～表15中的内容进行整理以得到表6～表12。在数据分析网元确定是推导UE移动性的预测结果，则上述步骤303可以通过以下方式实现：数据分析网元根据移动性相关信息得到用于预测终端在第一时间段内的各个子时间段的位置的时间顺序以及终端在某个位置的驻留时间的信息的移动性分析信息。
可选的，数据分析网元除了向第二网元提供第三指示信息外，还可以向数据分析网元提供第四指示信息。其中，第四指示信息用于指示所述第二网元上报所述终端在每个位置的驻留时间的信息。这样第二网元在接收到第四指示信息之后便可以根据时间上相邻的各个位置的时间信息得到终端在各个位置的驻留时间的信息。然后，第二网元向数据分析网元反馈的移动性相关信息中便可以包括终端在各个位置的驻留时间的信息。
下述以第一网元为consumer NF网元，数据分析网元为NWDAF网元，一个或多个第二网元包括AMF网元、AF网元以及OAM网元为例，描述本申请实施例提供的一种数据分析方法的具体实施例，如图4所示，该方法包括：

Analytics target period，指示想要获取的统计或者预测信息的时间段。
可以理解的是，如果第一服务操作中携带移动性分析针对的目标(比如一个或多个终端的标识)，则表示consumer NF网元希望数据分析网元提供一个或多个终端的标识所指示的全部终端中每个终端的移动性分析结果。如果第一服务操作中未携带移动性分析针对的目标，则表示consumer NF网元希望数据分析网元提供分析过滤信息限定的数据分析的范围内每个终端的移动性分析结果。
在本申请的另一个可能的实现中，第一服务操作还可以包括如下参数中的一个或多个：

期望的位置信息的粒度(preferred granularity of location information)：用于表示consumer NF网元期望的位置信息的粒度，如TA粒度或者cell粒度。
比如，如果期望的位置信息的粒度为TA，则移动性分析信息中包括的位置信息即为终端所在的TA。如果期望的位置信息的粒度为cell，则移动性分析信息中包括的位置信息即为终端所在的cell。
步骤402.NWDAF网元通过第二服务操作向AMF网元请求终端的移动性信息(对 应上述移动性相关信息)，相应的，AMF网元接收来自数据分析网元的第二服务操作。
作为一种示例，第二服务操作可以为NWDAF网元向AMF网元发送的事件开放订阅(Namf_EventExposure_Subscribe)服务操作。

在本申请的一个可能的实现中，第二服务操作中还可以携带目标区域的信息，以便于AMF网元确定提供终端在目标区域内的移动性相关信息。
可选的，在第二服务操作中包括终端1的标识，第三时间段以及目标区域的信息的情况下，表示NWDAF网元希望AMF网元提供终端1在第三时间段内位于目标区域的移动性相关信息。
步骤403.AMF网元通过事件开放通知服务操作(Namf_EventExposure_Notify服务操作)向NWDAF网元发送AMF网元收集到的终端的移动性相关信息。相应的，NWDAF网元接收来自AMF网元的Namf_EventExposure_Notify服务操作。
可以理解的是，Namf_EventExposure_Notify服务操作中携带AMF收集到的终端的移动性信息。
AMF网元收集到的终端的移动性相关信息的内容，如表1所示，此处不再赘述。
步骤404.NWDAF网元通过第三服务操作向AF网元请求终端的移动性相关的业务数据(对应上述第一信息)，相应的，AF网元接收来自NWDAF网元的第三服务操作。
作为一种示例，第三服务操作可以为NWDAF网元向AF网元发送的事件开放订阅(Naf_EventExposure_Subscribe)服务操作。其中，Naf_EventExposure_Subscribe服务操作用于请求AF网元提供终端的移动性相关的业务数据。第三服务操作中可以携带用于指示AF网元提供终端的移动性相关的业务数据的指示，本申请实施例对此不做限定。
在本申请的一个可能的实现中，第三服务操作中可以包括以下信息中的一个或多个：一个或多个终端的标识、目标区域的信息、目标时间段的信息、目标应用的信息。
在本申请的一个可能的实现中，第三服务操作中携带终端的标识的情况下，表示NWDAF网元希望AF网元确定指定终端的移动性相关信息。
在本申请的一个可能的实现中，第三服务操作中携带目标应用的信息的情况下，表示NWDAF网元希望AF网元确定访问目标应用的一个或多个终端的移动性相关信息。
在本申请的一个可能的实现中，第三服务操作中携带目标时间段的信息，表示 NWDAF网元希望AF网元确定目标时间段内终端的移动性相关信息。
以第三服务操作包括目标时间段以及目标应用为例，则AF网元便可以确定向NWDAF网元提供在目标时间段内访问目标应用的一个或多个终端的移动性相关信息。另，如果第三服务操作除目标时间段以及目标应用外还包括终端1的标识，则AF网元便可以确定向NWDAF网元提供终端1在目标时间段内访问目标应用的移动性相关信息。
步骤405.AF网元在收集得到终端的移动性相关信息之后通过第四服务操作向NWDAF网元发送终端的移动性相关信息。相应的，NWDAF网元通过第四服务操作接收来自AF网元的终端的移动性相关信息。
上述步骤404和步骤405中的AF网元可以是核心网内部的AF网元或者第三方AF网元，本申请实施例对此不做限定。
作为一种示例，第四服务操作可以为AF网元向NWDAF网元发送的事件开放通知(Naf_EventExposure_Notify)服务操作。
步骤406.NWDAF网元从OAM网元收集终端的移动性相关信息。
可以理解的是，上述NWDAF网元可以从AF网元、AMF网元或者OAM网元中的一个或多个网元中获取终端的移动性相关信息，换言之，NWDAF网元可以执行上述步骤402、步骤404以及步骤406中的一个，也可以全部都执行。
步骤407.NWDAF网元根据收集的数据和第一指示信息，推导统计或预测的终端的移动性数据分析信息。
关于步骤407的具体实现可以参考上述表6～表12处的描述，此处不再赘述。
步骤408.NWDAF网元通过分析信息响应(Nnwdaf_AnalyticsInfo_Response)服务操作或者分析信息订阅通知(Nnwdaf_AnalyticsSubscription_Notify服务操作)向consumer NF网元发送终端的移动性分析信息。
如图4所示的实施例中，consumer NF网元在向NWDAF网元订阅/请求终端的移动性分析信息时携带顺序指示，以指示NWDAF网元在终端的移动性分析信息中通过实施例中四种方式的其中一种方式携带用于指示终端的位置的先后顺序的信息，便于辅助consumer NF网元进行数据处理或者信息决策。
如图5所示，图5为本申请实施例提供的另一种数据分析方法的具体实施例，该方法包括：
步骤501、同步骤401，此处不再赘述。
步骤502、NWDAF网元通过第二服务操作向AMF网元请求终端的移动性信息(对应上述移动性相关信息)，相应的，AMF网元接收来自数据分析网元的第二服务操作。其中，第二服务操作中携带顺序指示。
可选的，第二服务操作中还可以携带驻留时间指示。
关于第二服务操作的具体介绍可以参考步骤402处的描述，此处不再赘述。
步骤503、AMF网元根据第二服务操作，收集终端的移动性信息，以得到NWDAF网元请的终端的移动性相关信息。
可以理解的是，由于第二服务操作中携带顺序指示，则AMF网元收集到终端的移动性信息(如表1所示)后，便可以处理收集到的移动性信息，以得到表6、表8、 表10或表11所示的内容。即AMF网元向NWDAF网元发送的移动性相关信息可以如表6所示的：包括一个时间段内终端在各个位置的时间信息。或者，AMF网元向NWDAF网元发送的移动性相关信息可以如表8所示的：包括终端在一段时间内的各个位置按照时间递增或递减的排序结果。或者，AMF网元向NWDAF网元发送的移动性相关信息可以如表10所示的：在一个时间段内包括终端的一个位置。
在本申请的一个可能的实现中，在第二服务操作中携带驻留时间指示的情况下，AMF网元收集到终端的移动性信息(如表1所示)后，便可以处理收集到的移动性信息，以得到表7、表9、表12所示的内容。即AMF网元向NWDAF网元发送的移动性相关信息可以如表7所示的：包括一个时间段内终端在各个位置的时间信息，以及终端在各个位置的驻留时间的信息。或者，AMF网元向NWDAF网元发送的移动性相关信息可以如表9所示的：包括终端在一段时间内的各个位置按照时间递增或递减的排序结果，以及终端在各个位置的驻留时间的信息。或者，AMF网元向NWDAF网元发送的移动性相关信息可以如表12所示的：在一个时间段内包括终端的一个位置，以及终端在各个位置的驻留时间的信息。
可以理解的是，在第二服务操作中携带顺序指示的情况下，图5所示的方案和图4所示的方案的区别在于：在图4中由NWDAF网元整理如表1所示的内容，得到表6、表8、表10或表11所示的内容。在图5中由AMF网元整理如表1所示的内容，得到表6、表8、表10或表11所示的内容。
具体的，终端在各个位置的驻留时间的信息可以由AMF网元根据时间上相邻的各个位置所关联的时间信息确定。
步骤504，同步骤403。区别在于：步骤403中终端的移动性相关信息未进行如步骤503处的处理，而步骤504中终端的移动性相关信息已由AMF网元进行了处理。
步骤505～步骤509，同步骤404～步骤408，此处不再赘述。
但是，步骤505～步骤509与步骤404～步骤408的区别在于：步骤505、步骤507中，NWDAF网元向AF网元或者OAM网元请求终端的移动性相关信息时还向AF网元或者OAM网元提供顺序指示和/或驻留时间指示。这时对于AF网元或者OAM网元即便可以对收集到的如表2所示的内容进行处理，以得到如表6～表15所示的内容，并作为终端的移动性相关信息提供给NWDAF网元。
步骤508与步骤408的区别在于：在步骤508中，因为AMF/AF/OAM已经根据order indication和residence time indication对数据进行了所需的处理，NWDAF网元只需将收集的信息进行处理即可得到移动性分析信息，比如确定第一时间段包括的各个子时间段的开始时间信息以及时长信息。如果是推导终端的移动性的预测结果，则NWDAF网元在得到预测结果之后，还需根据order indication和residence time indication对预测结果进行处理，以能够在预测的UE移动性分析结果中指示出UE位置的时间顺序以及UE在某个位置的驻留时间的信息。
在图5所示的实施例中，NWDAF网元在向AMF网元/AF网元/OAM网元请求/订阅终端的移动性相关信息时可以携带顺序指示和/或驻留时间指示，以指示AMF网元/AF网元/OAM网元在提供的终端的移动性相关信息中能够指示出终端的位置的时间顺序以及终端在某个位置的驻留时间的信息，辅助consumer NF网元进行数据处理 或者信息决策。
值得说明的是，在NDWAF网元未向AMF网元/AF网元/OAM网元提供order indication和residence time indication的情况下，AMF网元/AF网元/OAM网元也可以对收集到的终端的移动性信息进行处理，以得到用于指示终端位置的时间顺序以及终端在某个位置的驻留时间的信息的移动性相关信息。
