本公开实施例中提供了一种漫游场景下传输数据的方法。图2是根据一示例性实施例示出的一种漫游场景下传输数据的方法的流程图。如图2所示,该方法包括步骤S201~S205,具体的:
步骤S201,拜访地网络数据分析功能V-NWDAF根据拜访地网络功能V-Consumer NF的第一请求消息,向归属地网络数据分析功能H-NWDAF发送第二请求消息,第二请求消息用于请求分析信息。
步骤S202,H-NWDAF接收V-NWDAF发送的第二请求消息。
步骤S203,在通过H-NWDAF基于用户同意的验证后,H-NWDAF向V-NWDAF发送用于指示分析信息的第一消息。
步骤S204,V-NWDAF接收H-NWDAF发送的第一消息。
步骤S205,V-NWDAF向V-Consumer NF发送用于指示分析信息的第二消息。
其中,V-NWDAF与V-Consumer NF位于VPLMN侧,H-NWDAF位于HPLMN。
Consumer NF用于标识请求分析信息(analytics information)的主体或网元。V-Consumer NF可以是VPLMN侧任一请求设定数据或需要使用设定数据的网元。
在一些可能的实施方式中,第一请求消息例如为:
Nnwdaf_AnalyticsSubscription_Subscribe()。
在一些可能的实施方式中,该方法在步骤S201之前还可以包括步骤S200,具体的:
步骤S200,V-NWDAF接收V-Consumer NF的第一请求消息。
在一示例中,第一请求消息中包括以下至少之一:分析信息对应的用户标识(UE ID),分析信息对应的数据处理标识(Data Processor ID)。
在一些可能的实施方式中,用户标识(UE ID)可以包括多种形式,可以唯一标识用户设备或用户设备中的SIM卡。例如,该用户标识可以为用户隐藏标识(Subscription Concealed Identifier,SUCI)、用户永久标识(Subscription Permanent Identifier,SUPI)或者其他可以标识UE的ID。其中,SUPI是网络运营商为每个SIM卡分配的唯一标识符,SUCI是经过加密方案隐藏SUPI后生成的标识。
在一些可能的实施方式中,数据处理标识可以是PLMN ID、应用ID(Application ID)、服务ID(Service ID)、分析任务ID(analytics ID)或者是其他可以标识该数据处理任务的ID,在此不做限定。
以数据处理标识为分析任务ID为例进行说明,每个分析任务都对应一个分析任务标识,例如:分析任务1对应analytics ID1,分析任务2对应analytics ID2等。
在一些可能的实施方式中,第二请求消息例如为Analytics Request()。
