下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做 出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
目前,感知数据(例如动态3D地图、车辆周围的物体信息、某辆车与周围车辆的距离/方向信息等)的获取功能主要由应用层的应用服务器来实现,在这种技术方案中,需要每个应用服务器都能够支持感知相关功能,由此增加了应用层的实现复杂度和维护难度。
针对上述问题,本公开提出在移动通信网络架构中设置感知功能实体,该感知功能实体是为移动通信网络支持感知功能而设置的一种功能实体,感知功能实体负责收集感知数据,也可以支持对感知数据进行处理,形成应用所需的数据,如图像或地图等。网络上的各节点(如终端(User Equipment,UE)、网络设备或外部应用等)需要获取感知数据时,可以向感知功能实体发出请求,请求感知功能实体提供感知数据,感知功能实体可以根据接收到的请求,去获取相应的感知数据,提供给网络上的各节点。
感知功能实体可以位于核心网侧,也可以位于无线接入网侧。感知功能实体可以是独立的功能实体,也可以位于已有的核心网网元或无线接入网(Radio Access Network,RAN)节点中。感知功能实体可以与各核心网网元直接交互,也可以支持与应用功能实体(Application Function,AF)直接交互,还可以支持与终端或RAN节点直接交互。
基于移动通信网络中的感知功能实体,应用层的各应用服务器可以不再需要支持感知数据的获取功能,应用服务器需要获取感知数据时,可以直接通过移动通信网络向感知功能实体请求感知数据,从而降低了现有应用层的实现复杂度和维护难度。

步骤102、将感知数据传输至需要感知数据的第一通信设备。
具体地,感知功能实体确定满足第一请求消息的感知数据后,即可将这些感知数据传输给需要感知数据的第一通信设备,例如网络功能实体或应用功能实体或终端等。该第一通信设备可以是发送第一请求消息的通信设备,也可以是发送第一请求消息的通信设备以外的设备,即发送第一请求消息的通信设备可以是接收到第一通信设备的感知请求后向感知功能实体请求感知数据的,第一请求消息中可以携带第一通信设备的信息,以指示感知功能实体将感知数据传输至该信息对应的第一通信设备。
本公开实施例提供的感知数据传输方法,通过移动通信网络中设置感知功能实体,并支持其他网络节点从感知功能实体获取感知数据,从而任意通信设备均可通过移动通信网络获取感知数据,而无需自身支持感知数据获取功能,降低了各通信设备的复杂度、维护难度和生产成本,且能够通过移动通信网络为各通信设备提供有效的感知数据支持。

具体地,感知功能实体接收到第一请求消息后,若该第一请求消息中包含待请求的感知数据的属性信息,如数据类型信息、区域信息终端标识、服务质量QoS和时间信息中的一项或者多项,则可以根据这些属性信息,确定满足第一请求消息的感知数据。
其中,数据类型信息可以是感知数据类型,比如自动驾驶类、动态地图类、家庭应用控制类、距离、方向、角度、环境等等,也可以是请求感知数据的应用功能实体的标识等。区域信息可以是地理区域、终端标识或RAN节点标识等。时间信息可以是开始收集/感知/测量时间、结束收集/感知/测量时间、感知周期等等。
可选地,基于第一请求消息,确定满足第一请求消息的感知数据,包括:
基于第一请求消息,确定能够提供满足第一请求消息的感知数据的第二通信设备;
从第二通信设备中获取感知数据,并将获取到的感知数据确定为满足第一请求消息的感知数据。
具体地,感知功能实体在接收到第一请求消息后,可以根据第一请求消息中包含的待请求感知数据的相关信息,如数据类型信息、区域信息等,确定可提供满足第一请求消息的感知数据的第二通信设备,从第二通信设备中获取感知数据。例如,若需要获取特定区域的感知数据,则可以根据该区域信息选择第二通信设备;若需要获取特定终端的感知数据,则可以根据终端所在的位置信息,或为该终端服务的RAN节点信息等,选择第二通信设备。
可选地,第二通信设备可以为终端设备和无线接入网设备中的一种或者多种。
可选地,基于第一请求消息,确定能够提供满足第一请求消息的感知数 据的第二通信设备,包括:
基于第一请求消息中包含的区域信息和第二通信设备的位置信息,确定能够提供满足第一请求消息的感知数据的第二通信设备;或者,
基于第一请求消息中包含的区域信息,获取满足区域信息的至少一个第二通信设备的设备信息,并根据获取到的设备信息,确定能够提供满足第一请求消息的感知数据的第二通信设备。
具体地,感知功能实体确定第二通信设备,可以基于第一请求消息中包含的区域信息,如感知区域或终端标识等信息,根据第二通信设备的位置信息,确定能够提供满足第一请求消息的感知数据的第二通信设备,该第二通信设备的位置信息可以是本地配置的或者从其他网络功能实体如移动性管理功能实体获取到的,在此不做限制;或者,感知功能实体也可以基于第一请求消息中包含的区域信息,先获取满足该区域信息的至少一个第二通信设备的设备信息,再根据获取到的设备信息,确定能够提供满足第一请求消息的感知数据的第二通信设备。
例如,以第二通信设备为无线接入网设备为例,若感知功能实体内配置有RAN节点部署信息,如位置、拓扑或标识等,则感知功能实体可以根据第一请求消息中包含的区域信息和本地配置,确定能够提供满足第一请求消息的感知数据的RAN节点。
或者,感知功能实体也可以根据第一请求消息中包含的区域信息,向存储有RAN节点信息的其他网络功能实体请求满足该区域信息的至少一个RAN节点的信息,并根据获取到的RAN节点的信息,确定能够提供满足第一请求消息的感知数据的RAN节点。
可选地,基于第一请求消息中包含的区域信息,获取满足区域信息的至少一个第二通信设备的设备信息,包括:
基于第一请求消息中包含的区域信息,从网络存储功能实体或者移动性管理功能实体中获取满足区域信息的至少一个第二通信设备的设备信息。
具体地,网络存储功能(Network Repository Function,NRF)、统一数据管理功能(Unified Data Management,UDM)或移动性管理功能实体(例如, 移动性管理实体(Mobility Management Entity,MME)或接入及移动性管理功能(Access and Mobility Management Function,AMF))等网络功能实体中可以存储各种通信设备的信息,感知功能实体可以根据第一请求消息中包含的区域信息,从这些网络功能实体中获取满足该区域信息的至少一个第二通信设备的设备信息,以确定能够提供满足第一请求消息的感知数据的第二通信设备。
例如,感知功能实体可以向NRF请求RAN节点的信息,请求中携带区域或终端标识等信息,NRF基于这些信息向感知功能实体返回RAN节点的信息。
例如,感知功能实体还可以向UDM请求移动性管理功能实体的信息,请求中携带区域或终端标识等信息,UDM基于这些信息向感知功能实体返回移动性管理功能实体的信息。然后,感知功能实体再从移动性管理功能实体请求服务该区域或终端的RAN节点的信息。
可选地,若第二通信设备为无线接入网设备,那么从第二通信设备中获取感知数据,包括:
通过用户面功能实体,接收无线接入网设备发送的感知数据。
具体地,由于感知数据量较大,通过控制面传递,需要通过多条控制面消息传输感知数据,增加了数据传输时延。因此,本公开实施例中,若第二通信设备为无线接入网设备,感知功能实体可以通过用户面功能实体,接收无线接入网设备发送的感知数据。
例如,网络RAN节点和用户面功能实体(User plane Function,UPF)之间可以建立传输感知数据所需的数据传输路径(例如N3隧道,连接,会话等),RAN节点通过该路径传输感知数据,UPF通过IP路由的方式将该数据发送至感知功能实体。
可选地,通过用户面功能实体,接收无线接入网设备发送的感知数据,包括:
向移动性管理功能实体或者会话管理功能实体发送第一连接建立请求,第一连接建立请求用于请求建立无线接入网设备传输感知数据的连接;
根据建立的连接,接收无线接入网设备发送的感知数据。
具体地,通过用户面功能实体,接收无线接入网设备发送的感知数据的场景中,感知功能实体可以先判断是否已建立与发送感知数据相关的连接,若未建立,则可以向移动性管理功能实体或者会话管理功能实体发送第一连接建立请求,该第一连接建立请求用于请求建立无线接入网设备传输感知数据的连接,即感知功能实体可以向移动性管理功能实体发送连接建立请求,再由移动性管理功能实体向会话管理功能实体发送连接建立请求,也可以是感知功能实体直接向会话管理功能实体发送连接建立请求。其中,无线接入网设备传输感知数据的连接可以是指无线接入网设备与用户面功能之间传输数据的数据传输路径,如PDU会话或PDN连接等。

图2为本公开实施例提供的感知数据传输方法的流程示意图之二,该方法应用于第一网络侧设备,如图2所示,该方法包括如下步骤:
步骤200、接收感知数据获取请求,感知数据获取请求用于请求感知数据;
具体地,本公开实施例中,第一网络侧设备可以是指任意能够向感知功能实体请求获取感知数据的网络侧设备,如NEF、AMF等,第一网络侧设备在接收到感知数据获取请求(包括针对感知数据进行分析的分析请求)时,可以基于该感知数据获取请求,确定向感知功能实体请求获取感知数据。
其中,向第一网络侧设备发送感知数据获取请求的可以是任意需要获取 感知数据的通信设备,例如应用功能实体、终端或其他网络功能实体等,这些通信设备需要获取感知数据时,可以向第一网络侧设备发送感知数据获取请求,由第一网络侧设备向感知功能实体请求感知数据。
步骤201、基于感知数据获取请求,确定能够提供感知数据的感知功能实体,并向确定的感知功能实体发送第一请求消息;
具体地,第一网络侧设备接收到感知数据获取请求后,可以先根据感知数据获取请求来确定能够提供感知数据的感知功能实体,并向所确定的感知功能实体发送第一请求消息。
其中,感知数据获取请求中可以包含待请求的感知数据的属性信息,如数据类型信息、区域信息和时间信息中的一项或者多项,第一网络侧设备可以根据这些属性信息,例如感知类型、感知区域或RAN节点标识等,查询感知功能实体服务的区域、支持的感知类型或所处的RAN节点等信息,进而确定能够提供感知数据的感知功能实体。
在确定感知功能实体后,第一网络侧设备即可向确定的感知功能实体发送第一请求消息,请求感知功能实体提供感知数据。
第一请求消息中可以包含待请求的感知数据的属性信息,如数据类型信息、区域信息和时间信息中的一项或者多项。若第一网络侧设备请求感知功能实体将感知数据发送至第一网络侧设备以外的其他通信设备,则第一请求消息中还可以携带所述其他设备的信息。
步骤202、接收感知功能实体发送的感知数据。
具体地,第一网络侧设备向感知功能实体发送第一请求消息后,感知功能实体可以根据该第一请求消息,确定相应的感知数据,例如,可以是从本地存储的感知数据中确定满足第一请求消息的感知数据,也可以是从RAN节点或终端等其他设备去获取满足第一请求消息的感知数据。
感知功能实体确定满足第一请求消息的感知数据后,即可将这些感知数据传输给第一网络侧设备,从而第一网络侧设备可以获取到所请求的感知数据。
本公开实施例提供的感知数据传输方法,通过移动通信网络中设置感知 功能实体,并支持其他网络节点从感知功能实体获取感知数据,从而任意通信设备均可通过移动通信网络获取感知数据,而无需自身支持感知数据获取功能,降低了各通信设备的复杂度、维护难度和生产成本,且能够通过移动通信网络为各通信设备提供有效的感知数据支持。
可选地,该方法还包括:
将接收到的感知数据发送给发送感知数据获取请求的通信设备。
具体地,第一网络侧设备接收到感知功能实体发送的感知数据后,可以将接收到的感知数据发送给发送感知数据获取请求的通信设备,如应用功能实体、终端或其他通信设备。例如,对于应用功能实体通过NEF向感知功能实体请求感知数据的场景,NEF接收到感知功能实体发送的感知数据后,则可以将该感知数据发送给应用功能实体。
可选地,基于感知数据获取请求,确定能够提供感知数据的感知功能实体,包括:
根据感知数据获取请求和感知功能实体的感知能力,确定能够提供感知数据的感知功能实体;或者,
根据感知数据获取请求,从网络存储功能实体中查找能够提供感知数据的感知功能实体。
具体地,第一网络侧设备接收到感知数据获取请求后,可以根据感知数据获取请求和感知功能实体的感知能力,确定能够提供感知数据的感知功能实体。
其中,感知功能实体的感知能力可以是指感知功能实体的服务区域、支持的感知类型、支持的感知数据上报方式等,若感知功能实***于RAN节点,则还可以包括感知功能实体所处的RAN节点信息。因此,第一网络侧设备可以通过感知功能实体的感知能力,以及感知数据获取请求中包含的待请求的感知数据的属性信息,确定能够提供感知数据的感知功能实体。
例如,若感知数据获取请求中携带有感知类型、感知区域或RAN节点标识等信息,则可以在查询各终端的感知能力后,筛选出与这些信息匹配的感知功能实体。
第一网络侧设备接收到感知数据获取请求后,也可以根据感知数据获取请求,从网络存储功能实体中查找能够提供感知数据的感知功能实体。
具体地,为了支持其他网元选择感知功能实体,感知功能实体可以将自身的感知能力信息注册到网络存储功能实体中,从而其他网元可通过查找网络存储功能实体选择感知功能实体。感知功能实体的感知能力信息可以包括服务区域,能力(例如支持的感知类型,支持的感知数据上报方式,如果感知上报方式为用户面上报,则还可能提供感知功能实体的IP地址和/或端口号信息等),如果感知功能实***于RAN节点,则消息还可能包括RAN节点的标识。
具体地,感知功能实体可以将自身的感知能力信息注册到网络存储功能实体之后,其他网元如第一网络侧设备即可向网络存储功能实体发送查询请求,在请求消息中携带感知类型、感知区域和无线接入网设备标识等参数,从而网络存储功能实体可以向第一网络侧设备回复这些参数所对应的感知功能实体的信息。
可选地,第一请求消息中包含第一网络侧设备的地址信息,则接收感知功能实体发送的感知数据,包括:
通过用户面功能实体,接收感知功能实体发送的感知数据。
具体地,由于感知数据量较大,通过控制面传递,需要通过多条控制面消息传输感知数据,增加了数据传输时延。因此,本公开实施例中,第一网络侧设备可以在发送给感知功能实体的第一请求消息中携带第一网络侧设备的地址信息,从而感知功能实体可以根据该地址信息,通过用户面功能实体,向第一网络侧设备传输感知数据。其中,第一网络侧设备的地址信息可以是第一网络侧设备的IP地址、端口号或FQDN等信息。
图3为本公开实施例提供的感知数据传输方法的流程示意图之三,该方法应用于移动性管理功能实体,如图3所示,该方法包括如下步骤:
步骤300、向会话管理功能实体发送第二连接建立请求,第二连接建立请求用于请求建立无线接入网设备传输感知数据的连接。
具体地,由于感知数据量较大,通过控制面传递,需要通过多条控制面消息传输感知数据,增加了数据传输时延。因此,本公开实施例中,针对无 线接入网设备向感知功能实体传输感知数据的应用场景,无线接入网设备可以通过用户面功能实体,向感知功能实体传输感知数据。
在该场景中,移动性管理功能实体可以向会话管理功能实体发送第二连接建立请求,以请求建立无线接入网设备传输感知数据的连接。
其中,第二连接建立请求中可以携带以下一项或多项信息:连接标识;DNN;S-NSSAI;感知功能实体的标识;感知功能实体的IP地址;感知功能实体的端口号;感知功能实体的FQDN;感知功能实体的位置信息;RAN节点的位置信息。
本公开实施例中,连接建立请求的触发,可以是移动性管理功能实体接收到无线接入网设备发送的感知确认信息后确定的,也可以是移动性管理功能实体接收到感知功能实体或无线接入网设备发送的连接建立请求后确定的,也就是说,感知功能实体可以首先触发连接建立过程,然后向移动性管理功能实体发送连接建立请求,也可以是无线接入网设备首先触发连接建立过程,然后向移动性管理功能实体发送连接建立请求。之后移动性管理功能实体向会话管理功能实体发送第二连接建立请求,会话管理功能实体接收到该第二连接建立请求后,可以基于该第二连接建立请求与用户面功能实体之间执行连接建立过程,建立无线接入网设备传输感知数据的连接。
可选地,向会话管理功能实体发送第二连接建立请求之前,该方法还包括:
基于无线接入网设备的位置信息和感知功能实体的位置信息,确定会话管理功能实体。
具体地,移动性管理功能实体在向会话管理功能实体发送第二连接建立请求之前,可以基于无线接入网设备的位置信息和感知功能实体的位置信息,选择会话管理功能实体。
图4为本公开实施例提供的感知数据传输方法的流程示意图之四,该方法应用于会话管理功能实体(Session Management Function,SMF),如图4所示,该方法包括如下步骤:
步骤400、接收移动性管理功能实体或感知功能实体发送的第三连接建 立请求,第三连接建立请求用于请求建立无线接入网设备传输感知数据的连接;
步骤401、基于第三连接建立请求,与用户面功能实体之间执行连接建立过程。
具体地,为建立无线接入网设备传输感知数据的连接,本公开实施例中,可以由移动性管理功能实体向会话管理功能实体发送连接建立请求,也可以是由感知功能实体直接向会话管理功能实体发送连接建立请求,会话管理功能实体接收到连接建立请求后,可以基于该连接建立请求,与用户面功能实体之间执行连接建立过程。该过程可以是N4会话建立过程,或其他连接建立过程,过程为用户面功能实体分配了传输感知数据的隧道的隧道端点信息,之后会话管理功能实体可以将为用户面功能实体分配的隧道端点信息发送至无线接入网设备。
可选地,第三连接建立请求中可以携带以下一项或多项信息:连接标识;DNN;S-NSSAI;感知功能实体的标识;感知功能实体的IP地址;感知功能实体的端口号;感知功能实体的FQDN;感知功能实体的位置信息;RAN节点的位置信息。
可选地,第三连接建立请求中包括无线接入网设备的位置信息和感知功能实体的位置信息;
与用户面功能实体之间执行连接建立过程之前,该方法还包括:
基于无线接入网设备的位置信息和感知功能实体的位置信息,确定用户面功能实体。
具体地,会话管理功能实体在与用户面功能实体之间执行连接建立过程之前,可以基于无线接入网设备的位置信息和感知功能实体的位置信息,选择用户面功能实体。
