技术领域
本申请实施例涉及通信技术领域，尤其涉及一种漫游数据处理方法、装置及系统。
背景技术
在第五代(5rd generation，5G)通信网络中，核心网引入了网络数据分析功能(network data analytics function,NWDAF)网元。NWDAF网元根据从一个或多个网元上收集到的终端的数据，基于大数据分析技术得到数据分析结果，并反馈给网元进行策略制定。
但是通常情况下，一个终端可以从一个省或国家漫游到另一个省或国家(简称：跨省漫游或跨国漫游)，或者一个终端可以从一个公共陆地移动网(Public Land Mobile Network，PLMN，称为归属地的PLMN)漫游到PLMN(称为拜访地的PLMN)。终端在拜访地的数据归属问题，直接影响到了终端应该向拜访地NWDAF还是归属地NWDAF请求数据分析结果。然而，拜访地NWDAF或归属地NWDAF如何收集到终端在漫游场景下的数据是当下亟需解决的技术问题。

本申请实施例中无论一个或多个终端60在归属地接入的核心网还是一个或多个 终端60在拜访地时接入的核心网可以为第5代核心网(例如，5G核心网(5G Core，5GC))或者第四代(4th generation，4G)核心网(例如，核心分组网演进(Evolved Packet Core，EPC)。当然，该核心网还可以为第三代移动通信技术(3rd Generation，3G)中的核心网，或未来其它的移动通信技术中的核心网，本申请实施例对此不作限定。
一个或多个终端60在归属地接入的核心网和一个或多个终端60在拜访地接入的核心网可以为同一代核心网，也可以为不同代核心网。例如，一个或多个终端60在归属地接入的核心网为5GC，该一个或多个终端60漫游至拜访地时接入的核心网可以为EPC或者3G中的核心网。又例如，一个或多个终端60在归属地接入的核心网为5GC，该一个或多个终端60漫游至拜访地时接入的核心网依旧可以为5GC。本申请实施例对此不作限定。
可以理解的是，如果一个或多个终端60接入的核心网为5GC，则该一个或多个终端60接入的接入网为5G网络中的接入网，此时接入网网元可以为5G网络中的接入设备或可以为无线接入设备(Radio Access Network，RAN)。例如下一代节点B(The Next Generation Node B，gNB)。如果一个或多个终端60接入的核心网为EPC，则接入网可以为4G网络中的接入网，此时接入网网元可以为演进型基站(evolved NodeB，eNB)。
本申请实施例中一个或多个终端60在漫游地接入的核心网和一个或多个终端60在归属地接入的核心网可以为统一运营商的核心网，也可以为不同运营商的核心网。当一个或多个终端60在漫游地接入的核心网和归属地接入的核心网为跨运营商的核心网时，不同运营商的核心网中的核心网网元或者不同运营商的接入网网元可以相互通信，也可以不通信。至于不同运营商的核心网中的核心网网元或者不同运营商的接入网网元之间是否通信可以取决于不同运营商之间的协商，本申请实施例对此不作限定。
例如，第一数据分析网元10和该第二数据分析网元40可以属于同一个运营商内部的数据分析网元。当然，该第一数据分析网元10和该第二数据分析网元40也可以属于不同运营商内部的数据分析网元。该第一数据分析网元10和该第二数据分析网元40之间可以存在通信接口，也可以不存在通信接口。例如，第一数据分析网元10和该第二数据分析网元40属于同一个运营商内部的数据分析网元时，该第一数据分析网元10和该第二数据分析网元40之间可以通过拜访地安全边缘保护代理(Visited Security Edge Protection Proxy，V-SEPP)以及归属地SEPP(H-SEPP)之间的N32接口通信，当然第一数据分析网元10也可以和第二数据分析网元40之间直接存在通信接口进行通信，比如Nx。同一个运营商内部的第一数据分析网元10和该第二数据分析网元40之间可以彼此交互终端在归属地或拜访地时在核心网网元或接入网网元上的数据。
需要说明的是，本申请实施例中一个或多个终端60的漫游场景可以存在如下解释：
1)、跨运营商漫游(也可以称为跨公共陆地移动网络(Public Land Mobile Network，PLMN)漫游)，与运营商A签约的终端从运营商A的网络移动到运营商B的网络。
对于跨运营商漫游场景，运营商A中的接入网网元可以作为该终端的归属地的接 入网网元。运营商A中的核心网网元可以作为该终端的归属地的核心网网元。运营商B中的接入网网元可以作为该终端的拜访地的接入网网元。运营商B中的核心网网元可以作为该终端的拜访地的核心网网元。
2)、同PLMN内跨省、跨国家或者跨地区漫游，指同一运营商的终端从归属省份(地区)A漫游到另一个省份(地区)B，在省份(地区)A和省份(地区)B该终端接入到同一个运营商的网络。或者同一运营商的终端从一个归属国家漫游到另一个国家，应理解，在不同国家该终端接入到同一运营商的网络。
需要说明的是，对于处于漫游场景的终端，归属地的核心网网元为该终端制定的服务策略和拜访地的核心网网元为该终端制定的服务策略可能不同。因此，对于该终端而言，终端需要了解应该向拜访地的数据分析网元还是归属地的数据分析网元请求数据分析结果。
比如，以运营商A为中国移动为例，运营商B为中国联通为例，中国移动的终端从中国移动所在网络移动到中国联通所在网络，中国联通可以限制该终端只能享受2G/3G网络服务，不能享受4G/5G网络服务。此时，如图2所示，归属地的数据分析网元可以为运营商A的H-数据分析网元。拜访地的数据分析网元可以为运营商B的V-数据分析网元。
比如，终端A从运营商A的归属地区A(例如，上海)，移动到运营商A的地区B(例如，浙江地区)，如果终端A在归属地区A没有流量限制，而在地区B有流量限制，那么归属地区A的归属地的数据分析网元或者拜访地区B的拜访地的数据分析网元除了分析该终端A在归属地区A的行为，还要分析该终端A在地区B的行为，以便分别控制。如图3所示，归属地的数据分析网元可以为运营商A在归属地区A的H-数据分析网元。拜访地的数据分析网元可以为运营商A在地区B的V-数据分析网元。
其中，在5GC中用户面网元对应的网元或实体可以为用户面功能(User plane function，UPF)网元、移动管理网元对应的网元或实体可以为接入与移动性管理功能(access and mobility management function，AMF)网元、会话管理网元对应的网元或实体可以为会话管理功能(Session Management Function，SMF)网元、策略控制网元对应的网元或实体可以为策略控制功能(Policy Control Function)网元、应用网元对应的网元或实体可以为应用功能(Application Function，AF)网元、网管网元对应的网元或实体可以为运行、管理和维护(运维)(operation，administration，and maintenance，OAM)网元(也可以称为运行管理维护网元)。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。
在EPC中移动管理网元对应的网元或实体可以为移动性管理实体(mobility management entity，MME)。用户面网元对应的网元或实体可以为公用数据网网关(public data network gateway，PDN GW，PGW)、服务网元(serving gateway，SGW)。策略控制网元对应的网元或实体可以为策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)。也就是说，4G核心网中，MME既具有会话管理功能，又具 有移动管理功能。数据分析网元在4G核心网中也可以称为网络数据分析网元。
示例性的，以核心网为5GC为例，如图4所示，在5GC中除了上述涉及到的核心网网元和接入网网元之外，还可以包括：鉴权服务器功能(authentication server function，AUSF)网元、网络切片选择功能(network slice selection function，NSSF)网元、网络能力开放功能(network exposure function，NEF)网元、用户数据库(User Data Repository，UDR)、统一数据管理(unified data management，UDM)网元、数据网络(data network，DN)。网络仓库贮存功能(network repository function，NRF)网元，该NSSF网元、UDR、NEF网元、NRF网元未体现在图4的架构图中，该NRF网元主要用于网元的发现。
其中，终端通过N1接口(简称N1)与AMF网元通信。AMF实体通过N11接口(简称N11)与SMF网元通信。SMF网元通过N4接口(简称N4)与一个或者多个UPF网元通信。一个或多个UPF网元中任意两个UPF网元通过N9接口(简称N9)通信。UPF网元通过N6接口(简称N6)与AF网元管控的数据网络(data network，DN)通信。终端通过接入网网元(例如，RAN设备)接入网络，接入网网元与AMF网元之间通过N2接口(简称N2)通信。SMF网元通过N7接口(简称N7)与PCF网元通信，PCF网元通过N5接口与AF网元通信。接入网网元通过N3接口(简称N3)与UPF网元通信。任意两个AMF网元之间通过N14接口(简称N14)通信。SMF网元通过N10接口(简称N10)与UDM通信。AMF网元通过N12接口(简称N12)与AUSF通信。AUSF网元通过N13接口(简称N13)与UDM网元通信。AMF网元通过N8接口(简称N8)与UDM网元通信。
应理解，如图4所示的网络架构中，控制面网元也可以采用服务化接口进行交互。例如，如图5所示，AMF网元、SMF网元、UDM网元、或者PCF网元采用服务化接口进行交互。比如，AMF网元对外提供的服务化接口可以为Namf。SMF网元对外提供的服务化接口可以为Nsmf。UDM网元对外提供的服务化接口可以为Nudm。PCF网元对外提供的服务化接口可以为Npcf。应理解，各种服务化接口的名称的相关描述可以参考23501标准中的5G系统架构(5G system architecture)图，在此不予赘述。
需要说明的是，图4或图5仅是示例性的给出一个UPF网元、SMF网元。当然，该中可能包括多个UPF网元、SMF网元，如包括SMF网元1和SMF网元2，本申请实施例对此不作具体限定。
需要说明的是，图4或图5的接入网网元、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，接入网网元、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。
以图1所示的通信系统应用于如图6所示的漫游5G网络架构中的归属路由(home routed)场景为例。其中，归属路由场景指终端在拜访地时，DN由归属地提供。
如图6所示，该归属路由场景中包括拜访公共陆地移动网(visited public land  mobile network，VPLMN)和归属公共陆地移动网(home public land mobile network，HPLMN)。
其中，VPLMN包括：终端、RAN、拜访地的AMF网元、拜访地的SMF网元、拜访地的NSSF网元、拜访地的NEF网元、拜访地的NRF网元、拜访地的PCF网元、拜访地的UPF网元以及拜访地的SEPP(V-SEPP)。归属PLMN包括：归属地的UPF网元、归属地的PCF网元、归属地的NSSF网元、归属地的SMF网元、归属地的AUSF网元、DN、归属地的AF网元、归属地的NRF网元、归属地的UDM网元、归属地的NEF网元以及归属地的SEPP(H-SEPP)。
其中，归属PLMN和拜访PLMN之间通过拜访地的SEPP和归属地的SEPP通信。归属地的SEPP和拜访地的SEPP之间具有N32接口。
如图7所示，以图1所示的通信系统应用于如图7所示的漫游5G网络架构中的本地疏导漫游场景为例。其中，本地疏导漫游场景指终端在拜访地时，DN由拜访地提供。
如图7所示，该本地疏导漫游场景包括：VPLMN和HPLMN。其中，VPLMN包括：终端、RAN、UPF网元、DN、拜访地的AMF网元、拜访地的SMF网元、拜访地的NSSF网元、拜访地的NEF网元、拜访地的NRF网元、拜访地的PCF网元、拜访地的AF网元、V-SEPP。HPLMN包括：H-SEPP、归属地的UDM网元、归属地的NRF网元、归属地的AUSF网、归属地的PCF网元以及归属地的NEF网元。
其中，归属PLMN和拜访PLMN之间通过拜访地的SEPP和归属地的SEPP通信。归属地的SEPP和拜访地的SEPP之间具有N32接口。
需要说明的是，对于图6和图7中各个网元之间的接口可以参考图4和图5中的描述，此处不再赘述。
终端(terminal)是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。终端也可以称为用户设备(User Equipment，UE)、接入终端(Access Terminal)、用户单元(User Unit)、用户站(User Station)、移动站(Mobile Station)、移动台(Mobile)、远方站(Remote Station)、远程终端(Remote Terminal)、移动设备(Mobile Equipment)、用户终端(User Terminal)、无线通信设备(Wireless Telecom Equipment)、用户代理(User Agent)、用户装备(User Equipment)或用户装置。终端可以是无线局域网(Wireless Local Area Networks，WLAN)中的站点(Station，STA)，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)设备、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、可穿戴设备以及下一代通信系统(例如，第五代(Fifth-Generation，5G)通信网络)中的终端或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端等。其中，5G还可以被称为新空口(New Radio，NR)。
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。
NWDAF可以从网元收集数据，并进行数据分析得到数据分析结果。NWDAF将数据分析结果反馈给核心网网元(比如，策略控制网元，以辅助策略控制网元制定策略)。比如，NWDAF可以收集端到端的业务数据(包括业务(Service)体验信息(平均意见分(mean opinion score，MOS))和网络数据(业务对应的服务质量(Quality of Service，QoS)流的带宽、时延、错误率等)。NWDAF基于业务数据和网络数据训练得到Service MOS模型。其中，Service MOS模型用于表征业务的Service MOS与网络QoS参数之间的对应关系。在实际业务进行中，NWDAF可以从网络侧收集该业务的QoS流的网络数据，基于上述Service MOS模型测量当前业务的Service MOS。NWDAF将测量所得Service MOS反馈给策略控制网元，用于调整业务的QoS参数。比如，如果Service MOS分过低，可以增加业务的带宽。因此为了精准的获取终端的业务体验需要及时了解终端在不同网元上的数据。
可以理解的是，本申请实施例中一种漫游数据处理方法中由第一数据分析网元执行的步骤也可以由应用于第一数据分析网元中的芯片执行，一种漫游数据处理方法中由第一网元执行的步骤也可以由应用于第一网元中的芯片执行。一种漫游数据处理方法中由第二网元执行的步骤，也可以由应用于第二网元中的装置执行，例如，芯片执行，下述实施例以一种漫游数据处理方法中的执行主体分别为第一数据分析网元、第一网元和第二网元为例进行描述。
实施例一
如图8所示，图8示出了本申请实施例提供的一种漫游数据处理方法的流程示意图，该方法包括：

步骤103、第一网元向第一数据分析网元发送终端在第一网元上的数据。

以第一网元为UPF网元为例，则步骤103具体可以通过以下方式实现：第一网元直接通过Nupf_EventExposure_Subscribe向第一数据分析网元发送终端在拜访地的UPF网元上的数据。或者拜访地的UPF网元通过拜访地的SMF网元向第一数据分析 网元发送终端在拜访地的UPF网元上的数据。
以第一网元为拜访地的AF网元，则步骤103具体可以通过以下方式实现：第一网元利用Naf_EventExposure_Notify向第一数据分析网元发送终端在拜访地的AF网元上的数据。
应理解，如果第一网元为拜访地的接入网网元，则终端在拜访地的接入网网元上的数据可以经过拜访地的网管网元或者拜访地的AMF网元或拜访地的SMF网元转发至第一数据分析网元。
在一种可能的实施例中，本申请实施例中涉及到的第一信息还包括以下信息中的任一个或者多个：用于指示所述终端处于漫游的指示信息，所述终端的会话所处的漫游场景，其中，所述漫游场景为归属地路由或者本地疏导。

步骤105、第一数据分析网元从第二网元接收终端在第二网元上的数据，终端在第二网元上的数据包括第一标识。
示例性的，第二网元也可以为接入网网元、终端、会话管理网元、用户面网元、策略控制网元、应用网元中的任一个。第二网元可以为拜访地的网元，也可以为归属地的网元。
需要说明的是，如果图8所示的方法适用于如图7所示的架构，则第二网元为拜访地的网元。此时，下述实施例中第一数据分析网元可以为拜访地的数据分析网元，也可以为归属地的数据分析网元。如果图8所示的方法适用于如图6所示的架构，则第二网元为归属地的网元，也可以为拜访地的网元。此时，下述实施例中第一数据分析网元可以为拜访地的数据分析网元，也可以为归属地的数据分析网元。
应理解，第二网元为上述接入网网元、终端、会话管理网元、用户面网元、策略控制网元、应用网元中的任一个时，第二网元向第一数据分析网元发送终端在第二网元上的数据的具体消息可以参考步骤103中的描述，后续不再赘述。
如果第二网元也为归属地的接入网网元，则终端在归属地的接入网网元上的数据可以参考终端在拜访地的接入网网元上的数据，此处不再赘述。
如果第二网元为归属地的移动管理网元，则终端在归属地的移动管理网元上的数据可以参考终端在拜访地的移动管理网元上的数据，此处不再赘述。
如果第二网元为归属地会话管理网元，则终端在归属地会话管理网元上的数据可以参考终端在拜访地的会话管理网元上的数据。

应理解，如果第二网元为与第一网元不同的拜访地的网元时，终端在拜访地的第二网元上的数据可以参考终端在第一网元上的数据，此处不再赘述。
步骤106、第一数据分析网元根据第一标识关联终端在第一网元上的数据以及终端在第二网元上的数据得到终端处于漫游时的数据。
本申请实施例提供一种漫游数据处理方法，该方法通过第一数据分析网元获取终端在拜访地的第一网元上的数据以及终端在第二网元上的数据。第一数据分析网元基于第一标识关联终端在拜访地的第一网元上的数据以及终端在第二网元上的数据。第一数据分析网元基于第一标识关联终端在至少两个网元(第二网元或拜访地的第一网元)上的数据中包括第一信息，便于后续第一数据分析网元基于关联后得到的终端在至少两个网元上的数据基于大数据分析技术得到终端处于漫游时的数据分析结果。
在一种可能的实现方式中，第一标识包括以下信息中的至少一个：第一网元的标识、第二网元的标识、第一网元为终端分配的标识、第二网元为终端分配的标识、终端的标识、终端的会话的标识、终端的会话管理上下文标识、终端的流的标识、互联网协议IP五元组、网络实例信息、所述终端的区域信息。
在一种可能的实现方式中，终端的流的标识为终端的业务的流的标识。
第一网元的标识可以用于标识第一网元。例如，第一网元为接入网网元，第一网元的标识为global RAN node ID或者global gNB ID或者RAN的IP地址。其中，如果第一网元的IP地址为内网IP地址，则需要网络实例信息(network instance)以及该IP地址唯一标识该第一网元。其中，接入网网元的标识用于唯一识别接入网网元。例如接入网网元的标识可以为Global RAN Node ID，全球唯一标识一个RAN。
第二网元的标识可以用于标识第二网元。例如，如果第二网元为接入与移动性管理功能网元，则第二网元的标识为全球唯一AMF标识(global unique AMF identifier，GUAMI)或者AMF的IP地址。例如，如果第二网元为用户面功能网元，则第二网元的标识为global UPF ID或者UPF的IP地址。例如，如果第二网元为终端，则第二网元的标识为终端的标识。其中，如果第一网元的IP地址为内网IP地址，则需要network instance以及该IP地址唯一标识该第一网元。
应理解，由于第一网元为终端分配的标识在第一网元内唯一，第二网元为终端分配的标识在第二网元内唯一。因此，示例性的，需要联合第一网元的标识或者第二网元的标识才能将终端在第一网元上的数据以及第二网元上的数据(包括终端在第二网元上的数据)进行正确关联。
终端的会话的标识可以用于识别终端的会话。终端的会话可以为5G网络中的分组数据单元(Packet Data Unit，PDU)，或者为4G网络中的公用数据网(Public Data Network，PDN)连接。例如终端的会话的标识可以为PDU Session ID。例如，终端的会话的标识可以为PDN连接中的默认承载标识(Default Bearer ID)。
终端的流的标识用于识别该终端的业务的流。例如，终端的流的标识可以为服务质量流(QoS flow)的标识(QoS Flow ID)。例如，终端的流的标识可以为承载的标识(Bearer ID)。例如终端的流还可以是业务模板流标识(Service Data Flow Identifier， SDF ID)。
需要说明的是，本申请实施例中任一个网元(例如，第一网元、第二网元、AMF网元、SMF网元、UPF网元等等)的标识，具体是该网元的ID或者网元的IP地址。
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。
示例性的，本申请实施例中终端的区域信息或者归属区域信息或者拜访区域信息可以为终端所在区域的以下信息中的一个或者多个：追踪区域标识(tracking area identifier，TAI)、追踪区域标识列表(list of TAI(s))、路由区域标识(routing area identifier，RAI)、路由区域标识列表(list of RAI(s))、小区标识(Cell ID)、小区标识列表(list of Cell ID(s))、地理区域标识(geographical area identifier)、网络码(network code，NC)、国家码(country code，CC)、城市码(city code)、县码(county code)。下述实施例中但凡涉及到终端的区域信息或者归属区域信息或者拜访区域信息均可以参考此处的描述，后续不再赘述。
本申请实施例中第一网元为终端分配的标识为第一网元在第一接口上为终端分配的标识。第二网元为终端分配的标识为第二网元在第二接口上分配的标识。其中，第一接口为第一网元和第二网元之间的接口。
示例1)、以第一网元为拜访地的移动管理网元、第二网元为拜访地的接入网网元为例，则第一接口为拜访地的接入网网元与拜访地的移动管理网元之间的接口。
例如，第一接口可以为N2接口。也即拜访地的接入网网元和拜访地的移动管理网元分别为终端在N2接口上分配一个唯一标识。示例性的，拜访地的接入网网元为终端在N2接口上分配的标识为RAN UE NGAP ID，拜访地的移动管理网元为终端在N2接口上分配的标识为AMF UE NGAP ID。其中，拜访地的接入网网元在N2接口上为终端分配的标识用于唯一标识一个终端的接入网网元的隧道标识。拜访地的移动管理网元在N2接口上为终端分配的标识用于唯一标识一个终端的移动管理网元的隧道标识。应理解，示例1)可以适用于如图7所示的场景。
示例2)、以第一网元为拜访地的会话管理网元、第二网元为归属地的会话管理网元为例，本申请实施例中第一接口为归属地的会话管理网元和拜访地的会话管理网元的接口。例如，第二接口可以为N16接口。
应理解，示例2)可以适用于如图6所示的场景。
示例3)、以第一网元为接入网网元、第二网元为拜访地的用户面网元为例，此时第一接口可以为如图4所示的系统中RAN和UPF网元之间的N3接口。也即接入网网元和UPF网元分别在N3接口上为终端分配标识，及AN Tunnel Info以及CN Tunnel Info。其中，AN Tunnel Info包括RAN的IP地址以及RAN为终端的会话分配的隧道 端点标识(tunnel endpoint identifier，TEID)。CN Tunnel Info包括UPF网元的IP地址以及SMF网元或者UPF网元为终端的会话分配的隧道端点标识(tunnel endpoint identifier，TEID)。
应理解，示例3)可以适用于如图7所示的场景。
示例4)、以第二网元为终端为例，此时第一接口可以为如图4所示的系统中RAN和终端之间的Uu接口，也即终端和接入网网元分别在Uu接口上为终端分配标识。其中，接入网网元在Uu接口上为终端分配的标识可以是小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)。
需要说明的是，接入网网元为终端在第一接口上分配标识之后，可以将接入网网元为终端在第一接口上分配标识发送给第二网元(例如，移动管理网元、会话管理网元、终端或者用户面网元)。第二网元(在第一接口上为终端分配标识之后，也可以将第二网元(在第一接口上为终端分配的标识发送给接入网网元。
在一种可能的实施例中，如图8所示，本申请实施例提供的方法在步骤106之后还可以包括：
步骤107、第一数据分析网元向第二数据分析网元发送终端处于漫游时的数据。
步骤108、第二数据分析网元接收来自第一数据分析网元的终端处于漫游时的数据。
在一种可能的实现方式中，本申请实施例中的步骤101具体可以提供以下方式实现：终端漫游到拜访地时，拜访地的第一网元根据终端的标识获取终端的归属PLMN标识。第一网元确定终端的归属PLMN标识与第一网元所属的PLMN标识不一致，则第一网元确定终端处于漫游。应理解，如果终端的归属PLMN标识与第一网元所属的PLMN标识不一致，第一网元可以确定终端处于跨PLMN漫游场景。
示例性的，第一网元可以通过如下方式获取终端的归属PLMN标识：终端在漫游到拜访地时，终端向拜访地的移动管理网元发送注册请求消息，该注册请求消息中可以携带终端的归属PLMN标识。如果第一网元为拜访地的移动管理网元则可以从注册请求消息中获取终端的归属PLMN标识。如果第一网元为拜访地的会话管理网元，可以从拜访地的移动管理网元处获取终端的归属PLMN标识。
具体的，注册请求消息中携带终端的标识SUPI，SUPI包括国际移动用户识别码(International Mobile Subscriber Identity，IMSI)和网络私有标识，IMSI中包括移动国家码(Mobile Country Code，MCC)、移动网络码(Mobile Network Code，MNC)和移动用户识别号(Mobile Subscriber Identification number，MSIN)，PLMN标识包括MCC和MNC，因此拜访地的第一网元可以比对SUPI内以及自身网元所属的PLMN标识中的MCC和MNC是否一致，确定终端是否处于漫游。
在另一种可能的实现方式中，本申请实施例中的步骤101具体可以提供以下方式实现：终端漫游到拜访地时，拜访地的第一网元根据终端的标识获取终端的归属PLMN标识。第一网元根据终端的标识从UDM网元或者UDR网元查询终端的标识对应的GPSI，其中GPSI中包括MSISDN。拜访地的第一网元(例如，AMF网元)通过移动台国际ISDN号码(Mobile Station International ISDN Number，MSISDN)确定终端的归属地，通过比对(拜访地)网元自身所属的区域信息。但是进一步比对MSISDN 中的城市信息，确定终端为同PLMN跨地区漫游。
示例性的，MSISDN包括国家码(比如中国86)、国内目的码(National Destination Code，NDC)、用户号码(Subscriber Number，SN)，(拜访地)网元可以通过NDC码(3位)以及SN的前4位确定终端所在归属地。
需要说明的是，本申请实施例中第一网元或第二网元可以主动决定向第一数据分析网元发送终端在第一网元或第二网元上的数据。即一旦第一网元或第二网元确定位于其覆盖范围内的终端处于漫游时，便可以主动向第一数据分析网元发送终端在第一网元或第二网元上的数据。另一方面，第一网元和第二网元可以在第一数据分析网元的请求下，决定向第一数据分析网元发送终端在第一网元或第二网元上的数据。
在一种可能的实施例中，如图8所示，本申请实施例提供的方法在步骤101之前，还包括：
步骤109、第一数据分析网元向第一网元/第二网元发送第一请求消息，该第一请求消息用于请求处于漫游的终端在第一网元/第二网元上的数据。
示例性的，如果第一网元/第二网元为AMF网元，则该第一请求消息可以为Namf_EventExposure_Subscribe或者第一请求消息可以携带在第一数据分析网元向第一网元发送的Namf_EventExposure_Subscribe中。
如果该第一网元/第二网元为SMF网元，则该第一请求消息可以为Nsmf_EventExposure_Subscribe或者第一请求消息可以携带在第一数据分析网元向第一网元/第二网元发送的Nsmf_EventExposure_Subscribe中。
如果该第一网元/第二网元为UPF网元，则第一数据分析网元先向SMF网元发送Namf_EventExposure_Subscribe。其中，Namf_EventExposure_Subscribe中携带第一请求消息。然后SMF网元利用N4会话修改(N4 Session Modification)消息向UPF网元发送第一请求消息。
如果该第一网元/第二网元为AF网元，则第一请求消息为Naf_EventExposure_Subscribe或者Naf_EventExposure_Subscribe中携带第一请求消息。
步骤110、第一网元接收来自第一数据分析网元上的第一请求消息。
需要说明的是，步骤109和步骤110仅是第一数据分析网元指示第一网元，一旦第一网元发现存在处于漫游的终端便需要向第一数据分析网元上报该终端在第一网元上的数据。在发送第一请求消息时，第一数据分析网元并不知道处于漫游的终端的标识。通过步骤109和步骤110，一旦第一网元确定存在处于漫游的终端，便可以执行步骤102和步骤103。
需要说明的是，如果第一网元主动向第一数据分析网元上报终端在第一网元上的数据，则步骤109和步骤110可以省略。
示例性的，第一请求消息可以包括以下信息中的任一个或多个：终端类型、区域信息、时间信息。便于第一网元确定收集终端在第一网元上的漫游数据的范围。
应理解，终端类型用于第一网元确定收集指定终端类型的终端在第一网元上的数据。终端类型可以以终端的操作系统区分。例如终端类型可以为采用苹果系统的终端或者采用安卓系统的终端或者采用windows系统的终端。例如，如果第一请求消息中携带的终端类型为采用windows系统的终端，如果拜访地的第一网元确定采用安卓系 统的终端和采用windows系统的终端均处于漫游，则拜访地的第一网元向第一数据分析网元上报采用windows系统的终端在拜访地的第一网元上的数据。
其中，区域信息可以为追踪区域(tacking area，TA，通过TAI标识)或TA列表(通过TAI list标识)或路由区域(routing area，RA，通过RAI标识)或者RA列表(通过RAI list标识)或者小区(Cell，通过CGI或者Cell ID标识)或者小区列表(Cell list，通过CGI list或者Cell ID list标识)。其中，TA列表包括至少一个TA。RA列表包括至少一个RA。
示例性的，时间信息可以为时间窗、时间段列表。时间信息，用于第一网元确定收集终端在第一网元上的数据的起始时间和截止时间。例如，从2019年3月1日到2019年3月8日。时间信息可以为起始时间和时间长度。或者起始时间和截止时间。该时间信息可以指示一个时间段，也可以指示多个不连续的时间段。
应理解，请求中包括的区域信息、时间信息、终端类型可以同时存在以使得第一网元确定收集终端在第一网元上数据的收集范围，也可以只存在一种。本申请实施例对此不作限定。例如，如果请求中包括的区域信息、时间信息、终端类型，以区域信息为TA1为例，时间信息为2019年3月1日到2019年3月8日，终端类型为安卓系统的终端为例，则第一网元可以确定收集2019年3月1日到2019年3月8日之间在TA1内安卓系统的终端在第一网元上的数据。
在一种可能的实现方式中，第一请求消息还可以包括第一指示信息，第一指示信息用于指示当终端处于漫游时上报数据。通过第一请求消息便于第一网元确定需要上报终端在漫游下的数据。
需要说明的是，步骤109和步骤110以第一网元为例介绍第一数据分析网元触发第一网元上报处于漫游的终端在第一网元上的数据。第一数据分析网元触发第二网元上报处于漫游的终端在第二网元上的数据的过程可以参考步骤109和步骤110。如果第一数据分析网元触发第二网元，在将步骤109和步骤110中的第一网元替换为第二网元即可。
在另一种可能的实施例中，如图8所示，本申请实施例提供的方法在步骤101之前还包括：
步骤111、第二数据分析网元向第一数据分析网元发送第二请求消息。其中，第二请求消息用于请求第一数据分析网元上报处于漫游场景的终端在拜访地的网元的数据。
步骤112、第一数据分析网元接收来自第二数据分析网元的第二请求消息。
应理解，步骤111和步骤112可以适用于第一数据分析网元和第二数据分析网元为同一个运营商的数据分析网元的场景。在实现过程中，如果第一数据分析网元和第二数据分析网元为不同运营商上的数据分析网元时，如果第一数据分析网元和第二数据分析网元之间可以相互通信，则步骤111和步骤112也适用。此外，如果第一数据分析网元和第二数据分析网元之间已协商好或第一数据分析网元可以主动获取处于漫游场景的终端在拜访地的网元的数据时，则步骤111和步骤112可以省略。
在一种可选的实施例中，第一数据分析网元向第一网元或第二网元发送第一请求消息之前，第一数据分析网元还需要确定第一网元的地址或标识、第二网元的地址或 标识。具体的，第一数据分析网元确定第一网元的地址或标识/第二网元的地址或标识可以通过以下方式具体实现：第一数据分析网元向NRF网元发送查询请求，该查询请求中包括以下信息中的至少一个：区域信息、数据分析结果标识(Analytic ID)、终端群组标识、终端类型。
在一种可选的实施例中，如图8所示，本申请实施例提供的方法在步骤107之前，还包括：
步骤113、第一数据分析网元从用户数据管理网元处确定第二数据分析网元的信息。
示例性的，第二数据分析网元的信息可以为第二数据分析网元的标识或地址。
在一种可能的实现方式中，本申请实施例中的步骤103具体可以通过以下方式实现：第一数据分析网元向用户数据管理网元发送第三请求消息，所述第三请求消息用于请求第二数据分析网元的信息，第三请求信息包括以下信息中的一项或多项：所述终端的标识、所述归属PLMN标识、归属区域。第一数据分析网元接收来自用户数据管理网元的第二数据分析网元的信息。
示例性的，第二数据分析网元的信息可以是第二数据分析网元的标识或者IP地址。
示例性的，如果第一数据分析网元为拜访地的数据分析网元，则用户数据管理网元可以为归属地的用户数据管理网元，第二数据分析网元可以为归属地的数据分析网元。如果第一数据分析网元为归属地的数据分析网元，则用户数据管理网元可以为拜访地的用户数据管理网元，第二数据分析网元可以为拜访地的数据分析网元，这时第三请求消息中的归属PLMN标识由拜访PLMN标识替换、归属区域由拜访区域替换。
上述实施例以第一网元为拜访地的接入网网元、第二网元为移动管理网元为例，详细介绍了第一数据分析网元或第二数据分析网元关联终端在拜访地的接入网网元上的数据和终端在拜访地的移动管理网元或归属地的移动管理网元的过程。在实际过程中，第一数据分析网元或第二数据分析网元还可以关联终端在移动管理网元上的数据和终端在会话管理网元上的数据。
为了关联终端在移动管理网元上的数据和终端在会话管理网元上的数据，终端在移动管理网元上的数据还包括第二标识，用于关联终端在移动管理网元上的数据和终端在会话管理网元上的数据。其中，会话管理上下文标识为会话管理网元内为终端唯一分配的会话标识，标识会话管理网元上唯一一个会话。其中，SM Context ID为会话管理网元为终端的会话分配的，然后发送给移动管理网元识别终端的会话信息。请继续结合图8，在一种可能的实施例中，本申请实施例提供的方法还包括：
步骤114、第一数据分析网元获取终端在会话管理网元上的数据。终端在会话管理网元上的数据包括第二标识。
需要说明的是，对于图6所示的场景，步骤114和步骤115中的会话管理网元可以为拜访地的会话管理网元，也可以为归属地的会话管理网元。对于图7所示的场景，步骤114和步骤115中的会话管理网元可以为拜访地的会话管理网元。
需要说明的是，本申请实施例中会话管理网元在向第一数据分析网元发送终端在会话管理网元上的数据可以通过以下方式实现：
方式一)、会话管理网元可以直接将终端在会话管理网元上的数据发送给第一数 据分析网元。
方式二)、会话管理网元可以将终端在会话管理网元上的数据发送给用户面网元，以由用户面网元将该终端在会话管理网元上的数据发送给第一数据分析网元。
方式二的好处是可以减少第一数据分析网元关联数据的复杂度、增加第一数据分析网元关联数据的正确率。
步骤115、第一数据分析网元根据第二标识关联终端在移动管理网元上的数据以及终端在会话管理网元上的数据。
应理解，经过步骤104-步骤106数据分析网元可以根据第一标识关联终端在拜访地的接入网网元上的数据和终端在移动管理网元上的数据，并将得到的数据通过第二标识关联终端在会话管理网元上的数据。
例如，终端在移动管理网元上的数据如表1所示可以为终端的位置信息、DNN、NSI、S-NSSAI中的任一个或多个。例如，终端的地理位置信息或区域信息，终端在会话管理网元上的数据可以为如表1所示的DNN、S-NSSAI、NSI中的任一个或多个。可以理解的是，终端在会话管理网元上的数据和终端在移动管理网元上的数据可以相同，也可以不相同。终端在会话管理网元上的数据和终端在移动管理网元上的数据不相同指：终端在会话管理网元上的数据和终端在移动管理网元上的数据中部分数据相同，部分数据不相同。
需要说明的是，虽然终端在会话管理网元上的数据和终端在移动管理网元上的数据有可能是同类型数据，但是终端在会话管理网元上的数据和终端在移动管理网元上的数据也可能因为信息收集范围(例如，时间窗、区域信息)的不同而存在差异。例如，以类型为DNN为例，终端在会话管理网元和移动管理网元上的数据如果为DNN，则终端在会话管理网元上的DNN可能是时间段1内该终端对应的DNN。终端在移动管理网元上的DNN可能是时间段2内该终端对应的DNN。这样第一数据分析网元便可以根据第一标识将终端在不同收集范围内位于不同网元上的数据进行关联，得到该终端的完整数据集。类型为S-NSSAI、NSI的示例可以参考类型为DNN的示例，本申请实施例在此不再赘述。
在一种可能的示例中，本申请实施例中的第二标识包括以下信息中的至少一项：终端的会话管理上下文标识(SM Context ID)、移动管理网元的标识、会话管理网元的标识、全球小区标识码(Cell Global ID，CGI)、终端的标识、终端的会话的标识。其中，CGI用于全球唯一标识一个小区，即终端所在小区。
示例性的，会话管理网元的标识可以为该会话管理网元的地址或者会话管理网元的ID。会话管理网元的ID用于全球唯一标识一个会话管理网元。
应理解，由于终端的SM Context ID仅在会话管理网元内唯一。因此，可选地，需要联合终端的SM Context ID以及会话管理网元的标识或者移动管理网元的标识中的至少一个才能将终端在移动管理网元以及会话管理网元上的数据进行正确关联。
为了关联终端在会话管理网元上的数据和终端在用户面网元上的数据，本申请实施例中终端在会话管理网元上的数据还包括第三标识，用于关联终端在会话管理网元上的数据和终端在用户面网元上的数据。继续结合图8，在另一种可能的实施例中，本申请实施例提供的方法还包括：
步骤116、第一数据分析网元获取终端在用户面网元上的数据，终端在用户面网元上的数据包括第三标识。
需要说明的是，对于图6所示的场景，步骤116和步骤117中的用户面网元可以为拜访地的用户面网元，也可以为归属地的用户面网元。对于图7所示的场景，步骤116和步骤117中的用户面网元可以为拜访地的用户面网元。
示例性的，第三标识包括以下信息中的至少一项：会话管理网元为终端的会话分配的标识、会话管理网元的标识、用户面网元的标识、终端的会话的标识、终端的流的标识、终端的标识。
示例性的，会话管理网元为终端的会话分配的标识为会话管理网元为终端的会话在第二接口上分配的标识，第二接口为会话管理网元与用户面功能网元之间的接口。例如，如图4所示，会话管理网元与用户面功能网元之间的接口可以为N4接口，会话管理网元为终端的会话在第二接口上分配的标识为N4 Session ID。
示例性的，终端在用户面网元上的数据可以为如表1所示的终端使用某个业务时的QoS flow数据。其中，QoS flow数据可以为该QoS flow的比特率(Bit Rate)、丢包率(Packet Delay)、包错误率(Packet Error Rate)。
示例性的，步骤116中第一数据分析网元可以通过如下方式获取终端在用户面网元上的数据。A)、a1、第一数据分析网元通过会话管理网元向用户面网元发送数据请求消息。b1、会话管理网元接收到来自第一数据分析网元的数据请求消息之后，会话管理网元通过N4消息向用户面网元发送数据请求消息。c1、用户面网元根据数据请求消息获取终端在用户面网元上的数据。d1、用户面网元通过服务化接口上报终端在用户面网元上的数据给第一数据分析网元。或者，B)、a1-c1以及d2。其中，d2、用户面网元通过N4消息上报终端在用户面网元上的数据给会话管理网元，会话管理网元进一步通过服务化接口上报终端在用户面网元上的数据给第一数据分析网元。C)、第一数据分析网元直接向用户面网元发送数据请求消息。
步骤117、第一数据分析网元根据第三标识关联终端在会话管理网元上的数据以及终端在用户面网元上的数据。
应理解，由于会话管理网元为终端的会话在第二接口上分配的标识为N4 Session ID仅在会话管理网元内唯一。因此，一种示例，需要联合终端的N4 Session ID以及会话管理网元的标识或者用户面网元的标识中的至少一个才能将终端在会话管理网元以及终端在用户面网元上的数据进行正确关联。
为了关联终端在用户面网元上的数据和终端在应用网元上的数据，本申请实施例中终端在用户面网元上的数据包括第四标识，用于关联终端在用户面网元上的数据和终端在应用网元上的数据。继续结合图8，在再一种可能的实施例中，本申请实施例提供的方法还包括：
步骤118、第一数据分析网元获取终端在应用网元上的数据，其中，终端在应用网元上的数据包括第四标识。
示例性的，终端在应用网元上的数据可以为如表1所示的业务体验(Service Experience)数据。
示例性的，步骤118中第一数据分析网元获取终端在应用网元上的数据的过程可 以参考现有技术中的描述，此处不再赘述。
需要说明的是，对于图6所示的场景，步骤118和步骤119中的应用网元可以为拜访地的应用网元，也可以为归属地的应用网元。对于图7所示的场景，步骤118和步骤119中的应用网元可以为拜访地的应用网元。
步骤119、第一数据分析网元根据第四标识关联终端在用户面网元以及终端在应用网元上的数据。
示例性的，本申请实施例中第四标识可以包括以下信息中的至少一项：互联网协议五元组(Internet Protocol 5-tuple，IP五元组)、终端的标识、用户面网元的标识、业务的业务标识、业务服务器的标识、应用网元的标识。
需要说明的是，本申请实施例用户面网元向第一数据分析网元上报终端在用户面网元上的数据时，携带的IP五元组为内网IP五元组，而应用网元向第一数据分析网元上报终端在应用网元上的数据时，携带的IP五元组为外网IP五元组，因此，步骤119中为实现这两部分数据关联，需要通过网络地址转换功能实体(network address translation，NAT)进行IP地址转换，具体有如下三种思路：
1)、用户面网元上报终端在用户面网元上的数据给第一数据分析网元时携带内网IP五元组，第一数据分析网元根据内网IP五元组向NAT网元查询内网IP五元组对应的外网IP五元组。在得到内网IP五元组对应的外网IP五元组之后，如果内网IP五元组对应的外网IP五元组和应用网元发送的外网IP五元组相同，则第一数据分析网元根据外网IP五元组关联终端在用户面网元以及终端在应用网元上的数据。
示例性的，一种可替换的实现方式如下：第一数据分析网元也可以根据终端在应用网元上的数据中携带的外网IP五元组从NAT网元查询外网IP五元组对应的内网IP五元组。如果外网IP五元组对应的内网IP五元组和终端在用户面网元上的数据中携带的内网IP五元组一致，则第一数据分析网元根据内网IP五元关联终端在用户面网元以及终端在应用网元上的数据。
2)、用户面网元根据内网IP五元组向NAT网元查询内网IP五元组对应的外网IP五元组，用户面网元上报终端在用户面网元上的数据时，向第一数据分析网元上报内网IP五元组对应的外网IP五元组。这样便于第一数据分析网元接收到终端在用户面网元上的数据中也携带外网IP五元组，从而根据外网IP五元组关联终端在用户面网元以及终端在应用网元上的数据。
示例性的，一种可替换的实现方式如下：应用网元根据外网IP五元组向NAT网元查询外网IP五元组对应的内网IP五元组，应用网元上报终端在应用网元上的数据时，携带外网IP五元组对应的内网IP五元组。这样便于第一数据分析网元接收到终端在应用网元上的数据中携带内网IP五元组，从而根据内网IP五元组关联终端在用户面网元以及终端在应用网元上的数据。
3)、终端在用户面网元上的数据携带内网IP五元组，终端在应用网元上的数据携带外网IP五元组，第一数据分析网元根据内网IP五元组与外网IP五元组之间的对应关系关联终端在用户面网元以及终端在应用网元上的数据。
应理解，第一数据分析网元中具有内网IP五元组与外网IP五元组之间的对应关系，该对应关系可以是预存储在第一数据分析网元中的，也可以由第一数据分析网元 从NAT网元处获得该对应关系。具体的，第一数据分析网元从NAT网元处获得该对应关系包括：NAT网元向第一数据分析网元主动上报该对应关系或者NAT网元根据第一数据分析网元的请求，向第一数据分析网元发送对应关系。
需要说明的是，本申请实施例中第一数据分析网元获取终端在任一个网元上的数据时，该网元在上报该数据时，可以将第一标识、或第二标识或第三标识或第四标识，携带在终端在该网元上的数据中。当然，该网元在上报终端在该网元上的数据时，还可以将终端在该网元上的数据和第一标识、或第二标识或第三标识或第四标识在同一个消息中上报给第一数据分析网元。
在一种可能的实现方式中，第一标识、第二标识、第三标识以及第四标识中还可以包括时间信息或者跟踪记录会话参考。该时间信息用于指示该第一标识、第二标识、第三标识以及第四标识的有效时间段或者时间间隔或者时隙或者时间窗或者时间戳或者时间点。该跟踪记录会话参考用于指示终端的追踪记录。
需要说明的是，如果为同PLMN下的跨地区漫游，如果第一数据分析网元为归属地的数据分析网元时，则拜访地的接入网网元、拜访地的会话管理网元、拜访地的移动管理网元、拜访地的策略控制网元、拜访地的应用网元、拜访地的用户面网元为同一个运营商中的网元，只不过这些网元分布在不同的国家或者省或市区。
需要说明的是，如果为跨PLMN漫游，如果第一数据分析网元为归属地的数据分析网元时，则拜访地的接入网网元、拜访地的会话管理网元、拜访地的移动管理网元、拜访地的策略控制网元、拜访地的应用网元、拜访地的用户面网元为同一个运营商中的网元，与归属地的数据分析网元所处PLMN不相同。
此外，无论是归属地的数据分析网元还是拜访地的数据分析网元关联终端在至少两个网元上的数据，在图6所示的场景中，第二网元(例如，移动管理网元)、步骤114和步骤115中的会话管理网元、策略控制网元、步骤118和步骤119中的应用网元、步骤116和步骤117中的用户面网元均可以为拜访地的相应网元，也可以为归属地的相应网元。而在图7所示的场景中，第二网元(例如，移动管理网元)、步骤114和步骤115中的会话管理网元、策略控制网元、步骤118和步骤119中的应用网元、步骤116和步骤117中的用户面网元均可以为拜访地的相应网元。
再者，对于图6所示的场景，如果第二网元为归属地的移动管理网元，则第一数据分析网元可以将终端在拜访地的接入网网元上的数据和终端在归属地的移动管理网元进行关联。
再本申请的另一个实施例中，如果拜访地的第一网元和归属地的第二网元为相同的网元，则第一数据分析网元可以对终端在拜访地的第一网元上的数据和终端在归属地的第二网元上的数据进行关联。例如，第一网元为拜访地的接入网网元。第二网元为归属地的接入网网元。或者第一网元为拜访地的移动管理网元，第二网元为归属地的移动管理网元。或者第一网元为拜访地的会话管理网元，第二网元为归属地的会话管理网元。或者第一网元为拜访地的用户面网元，第二网元为归属地的用户面网元。或者第一网元为拜访地的应用网元，第二网元为归属地的应用网元。或者第一网元为拜访地的策略控制网元，第二网元为归属地的策略控制网元。
上述实施例一，以第一网元为拜访地的接入网网元、第二网元为移动管理网元为 例，通过步骤101-步骤119描述了第一数据分析网元依次对终端在接入网网元上的数据、终端在移动管理网元上的数据、终端在会话管理网元上的数据、终端在拜访地或归属地的用户面网元上的数据以及终端在应用网元上的数据两两关联，最终得到完整的Service MOS模型训练数据的过程。下述实施例二将以第一网元为拜访地的接入网网元、第二网元为用户面网元为例，结合图9，详细介绍第一数据分析网元如何实现如下两个关联过程：
关联过程一、依次对终端在拜访地的接入网网元上的数据、终端在拜访地或归属地的用户面网元上的数据以及终端在拜访地或归属地的应用网元上的数据两两关联，最终得到完整的终端在拜访地的接入网网元、拜访地或归属地的用户面网元以及拜访地或归属地的应用网元上的数据的过程。可选的，关联后的数据可以用于Service MOS模型训练。
关联过程二、第一数据分析网元依次对终端在拜访地的接入网网元上的数据、终端在拜访地或归属地的用户面网元上的数据、终端在拜访地或归属地的会话管理网元上的数据、终端在拜访地或归属地移动管理网元上的数据两两关联，最终得到完整的终端在拜访地的接入网网元、拜访地或归属地的用户面网元、拜访地或归属地的会话管理网元以及拜访地或归属地移动管理网元上的数据的过程。可选的，关联后的数据可以用于Service MOS模型训练。
如图9所示，本申请实施例提供另一种漫游数据处理方法，该方法包括：
步骤201-步骤205，同上述实施例中步骤101-步骤105处的描述，此处不再赘述。
步骤206、第一数据分析网元根据第一标识关联终端在第一网元上的数据以及终端在拜访地或归属地的用户面网元上的数据得到终端处于漫游时的数据。
