Abstract

本申请提供了一种对UE进行感知的方法和通信装置，可以由SF网元、NEF网元、AMF网元、SMF网元或RAN网元等为感知请求者或UE执行针对UE的感知探测，并为感知请求者或UE提供相应的感知业务。在一些实现中，感知请求者可以是UE本身，也可以是应用功能AF。一般情况下，AF可以直接向通信系统(例如，5GS)请求感知业务；而UE可以向通信系统(例如，5GS)请求感知业务，也可以基于自身的感知需求直接从RAN网元请求感知资源进行感知，或者与RAN网元协作感知，并获得感知数据，从而能够快速高效地获得感知数据。另外，有一些实现不仅可以实现对UE的感知，还可以保护UE侧安全隐私。

本申请实施例中的接入网设备可以是无线接入网设备。
此外，上述“网元”也可以称为实体、设备、装置或模块等，本申请并未特别限定。并且，为了便于理解和说明，下文的部分描述中省略“网元”这一描述，例如，将NEF网元简称NEF，此情况下，“NEF”应理解为NEF网元或NEF实体，以下省略对相同或相似情况的说明。
应理解，图1仅是示例性的一种网络架构，适用本申请实施例的网络架构并不局限于此，任何能够实现上述各个网元的功能的网络架构都适用于本申请实施例。

接下来以5G系统(5G system,5GS)中的网元为例介绍具体的方案细节。可以理解的是，当该方案用于LTE系统，或者未来通信系统，方案中的各网元可以替换为具有相应功能的其他网元，本申请对此不作限定。
随着通信技术的演进，在未来的无线通信中，当RAN采用毫米波频段进行无线通信时，RAN将天然拥有类似雷达的感知能力，也即RAN将同时拥有无线通信能力和感知识别的能力。目前，业界只简单定义了使能感知服务的端到端的架构，鉴于当前的技术现状，例如，RAN网元的针对区域(即，per area)的感知精度可能无法满足某些特定应用需求(如L4以上自动驾驶)，以及缺乏为单个UE进行感知的技术等，目前，业界还没有针对具体UE进行感知的方案。
为此，本申请提供一种对UE进行感知的方法。
可替换地，在本申请各实施例中，感知服务数据可以称为感知数据、感知业务数据或感知应用数据。
以下所有实施例中的NEF网元也可以替换为网关感知中心(gateway sensing center， GSC)。即，各实施例中由NEF网元执行的操作和/或处理，可以由网关感知中心来执行。其中，网关感知中心用于接收来自感知需求者(sensing client)的感知请求，并向感知网元发送感知请求。
