步骤101：向NWDAF发送第一请求，所述第一请求用于获取第一终端的分析信息；
上述第一请求可以是分析(analytics)请求或订阅(subscribe)请求，可以理解的是，对该请求的名称不做限定。
上述NWDAF接收到第一请求之后，对第一终端的移动性进行分析，比如对第一终端的移动信息进行分析，和/或，对第一终端的位置变更进行分析。
或者，上述NWDAF接收到第一请求之后，如果第一请求中携带紧急指示(emergency indication)，则该NWDAF对第一终端的移动性进行分析，也就是，在本申请实施例中，NWDAF是通过第一请求中携带的紧急指示判断是否被允许对第一终端进行分析，并向NF返回第一终端的分析信息， 可选地，紧急指示可以表示该请求来自于第三方平台，比如紧急中心(emergency center)等，NWDAF基于紧急指示执行对第一终端进行移动性分析，提高用户隐私的安全性。
示例性地，第一请求中携带一个指示信息(相当于紧急指示)，比如：该指示信息可以为1比特指示位，该1比特指示位为“1”，表示该请求来自紧急中心，该1比特指示位为“0”，表示该请求来自除紧急中心之外的其他平台。或者，比如，该指示信息可以为特定字段，用该字段表示该请求是否来自紧急中心。
可以理解的是，在本申请实施例中对指示信息的名称不做限定，即，该指示信息可以称为紧急指示或者其他名称。
可以理解的是，第一终端可以包括：一个终端、一组终端、或任意终端(any UE，或者称为任何终端)，其中一组终端是指具有相同组标识(group ID)的终端，在本申请实施例中对组的划分方式不做具体限定，比如可以采用现有的方式将多个不同的终端配置相同的组标识，这样具有该组标识的多个不同的终端就属于一组终端。其中任意终端是指NF可以向服务区域内的NWDAF请求或订阅任意一个或多个终端的分析信息，以获得该一个或多个终端的移动信息(或者称为移动轨迹、运动轨迹)。
比如，NF可以向服务于区域A的NWDAF和服务于区域B的NWDAF分别发送第一请求，请求服务于区域A的NWDAF和服务于区域B的NWDAF对任意终端的移动性进行分析，比如分析任意终端的移动信息，可以理解的是，第一请求中可以携带该任意终端的标识，或者携带该任意终端的组标识，可以理解的是，在本申请实施例中对确定任意终端的具体方式不做限定。
可以理解的是，在本申请实施例中对于区域的范围不做限定，该区域可以对应于行政区域，或者对应于无线网络中的小区，或者对应于NWDAF服务区域中的至少部分区域。
需要说明的是，NF可以直接向NWDAF发送第一请求，或者NF也可以通过NEF向NWDAF发送第一请求。其中，向NWDAF发送第一请求是指，向NF服务区域内的一个或多个NWDAF发送第一请求。
步骤102：从NWDAF接收第一终端的分析信息(analytics information)；
比如，NF直接从NWDAF获取所述第一终端的分析信息；或者，NF通过NEF从NWDAF获取第一终端的分析信息。
可以理解的是，NWDAF可以根据第一请求采用现有的分析算法(比如移动性分析算法)对第一终端进行分析，得到该第一终端的分析信息，进一步地，该第一终端的分析信息可以包括以下一项或多项：第一终端的标识(UE标识)、第一终端的位置(UE位置)、与位置对应的时间信息(比如：时隙(time slot，或者称为时间片)等)。
步骤103：根据所述分析信息，生成所述第一终端的移动信息。
可以理解的是，由于NF可以汇总来自不同NWDAF的第一终端的分析信息，这样生成的第一终端的移动信息(或者称为移动轨迹或运动轨迹)可以包括该第一终端在不同区域内的移动信息，提高移动性分析的准确性和可靠性。
比如，在某些应急特殊场景下，NF通过上述步骤101～103可以汇总出特定地区中特定用户的移动信息，进而实现对该特定地区人群进行追踪。
在本申请实施例中，可以获取特定地区用户的移动信息，实现对特定地区用户的移动性监测，有利于运营商支撑疫情防控等应急事件的能力。

可选地，预定时间段包括：一个或多个时间片或时隙(time slot)，在本申请实施例对预定时间段的长度或形式不做具体限定。
可以理解的是，预定时间段内移动信息相同可以理解为：预定时间段内第一终端和第二终端所处的位置相同，比如，在2020-4-8上午9:00-10:00，第一终端和第二终端都出现在XX商场，则认为第一终端和第二终端在2020-4-8上午9:00-10:00移动信息相同，或者预定时间段内第一终端和第二终端的起始位置和目的位置均相同，比如，在2020-4-8上午9:00-10:00，第一终端和第二终端的起始位置是北京南火车站，目的位置是天津火车站，则认为第一终端和第二终端在2020-4-8上午9:00-10:00移动信息相同。
可以理解的是，NWDAF基于该第二请求，可以采用现有的移动信息相似度算法进行分析，NWDAF分析得到在特定时间内与第一终端具有相同移动信息的第二终端的信息，比如，NWDAF利用余弦相似度算法对第一终端的移动信息和第二终端的移动信息进行分析，如果移动信息的相似度超过预设值，则判定第二终端的移动信息与第一终端的移动信息相同。
步骤202：从NWDAF接收第二终端的信息。
进一步地，NF可以根据接收到的第二终端的信息汇总得到终端列表(UE列表)，所述终端列表中包括所述第二终端的信息，比如汇总得到第二终端的移动信息列表。
可以理解的是，第二终端在预定时间段内的移动信息与第一终端在预定时间段内的移动信息相同，从而可以将携带第二终端的用户判断或识别为是与携带第一终端的用户有密切接触的用户。因此，NF可以汇总得到与特定用户人群密切接触的终端列表。
可选地，第二终端的信息可以包括以下一项或多项：第二终端的标识 (UE标识)、第二终端的UE位置、时间信息(比如time slot)等。
可选地，所述第二终端包括：一个终端或一组终端。

示例性地，NWDAF可以判断所述第一请求中是否携带所述紧急指示；如果所述第一请求中携带所述紧急指示，则向所述NF返回所述第一终端的分析信息。也就是，NWDAF基于该紧急指示识别或判断其是否有权限或被允许对第一终端进行分析并向NF返回第一终端的分析信息。
在本申请实施例中，该第一终端的分析信息可以包括以下一项或多项：第一终端的标识(UE标识)、第一终端的位置(UE位置)、与位置对应的时间信息(比如：时隙(time slot，或者称为时间片))等。
