本公开的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本公开的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
在对本公开实施例的技术方案进行详细说明之前,首先对5G网络架构 进行简单说明。参照图1所示,5G网络的核心网采用服务化架构,各个网络功能之间采用服务化接口(Service Based Interface,SBI)。其中,各个网络功能的功能简述如下:

需要说明的是,图1中Nnef、Nnrf、Npcf、Nudm、Naf、Nausf、Namf、Nsmf、N1、N2、N3、N4,以及N6为接口序列号。这些接口序列号的含义可参见标准协议中定义的含义,在此不做限制。
上述架构中,控制面网元之间采用的是服务化架构,而控制面和用户面之间,还不是服务化的,因此提出了对用户面功能服务化的方案,例如增加以下方面的能力:
1、避免重复数据传输,减少传输路径
示例1:考虑PCF服务是否可以直接订阅/取消订阅UPF服务以获得QoS监控报告(端到端时延)。
2、从UPF中检索原始状态或实时业务流信息:
示例2:网络数据分析功能(Network Data Analytics Function,NWDAF)服务可以订阅/取消订阅UPF以检索实时服务流信息,例如,考虑不同服务的有效采样间隔,以便于数据收集和分析。
3、UPF事件曝光:
示例3:5G物联网解决方案需要将UPF连接到NEF/本地NEF,以便将网络信息暴露给应用服务器。
至少基于上述网络架构提出本公开以下各实施例。
