本申请实施例提供了信息传输方法及装置,用以现有终端位置的获取存在时延的问题。其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
如图1所示,为本公开实施例提供的信息传输方法的流程示意图,该方法应用于定位功能实体,其中,所述定位功能实体与无线接入网RAN设备之间配置直接通信接口。
需要说明的是,本公开实施例中涉及的定位功能实体可以是第5代(5 th Generation,5G)网络中的定位管理功能(Location Management Function,LMF)实体,第4代(4 th Generation,4G)网络中服务移动位置中心(Serving Mobile Location Centre,SMLC)功能实体,或者是第6代(6 th Generation,6G)网络中与定位相关的功能实体,这里不做具体限定。
该方法可具体包括:
步骤101:所述定位功能实体通过所述直接通信接口向无线接入网RAN设备发送第一请求消息,所述第一请求消息用于请求位置相关信息;
需要说明的是,通过定位功能实体与RAN设备之间配置的直接通信接口,能够在定位功能实体与RAN设备之间传递定位消息,无需移动性功能实体的转发,从而降低定位时延。
可选地,定位功能实体实体为部署在核心网内的定位功能实体,或者,定位功能实体为靠近RAN设备部署的定位功能实体。
需要说明的是,定位功能实体为靠近RAN设备部署的定位功能实体时,说明定位功能实体是从核心网下沉到RAN设备附近的本地定位功能实体,其适用于边缘计算场景。
这里,可选地,RAN设备为基站。
以5G网络中的LMF实体为例,LMF实体通过该LMF实体与RAN设备之间配置的直接通信接口,向RAN设备发送提供位置信息请求消息,具体的是LMF实体向RAN设备发送位置提供请求 (Nran_Location_ProvidePositioningInfo Request)消息。其中,提供位置信息请求消息可以理解为第一请求消息,该请求消息具体用于请求终端的位置或者请求与终端的位置相关的测量信息。
步骤102:所述定位功能实体接收所述RAN设备发送的针对所述第一请求消息的第一回复消息。
以5G网络中的LMF实体为例,LMF实体接收RAN设备发送的提供位置信息应答消息,具体的是:
LMF实体接收RAN设备发送的位置提供响应(Nran_Location_ProvidePositioningInfo Response)消息。
这里,LMF实体可根据提供位置信息应答消息,获得终端的位置信息。
本公开实施例的信息传输方法,通过在定位功能实体与无线接入网RAN设备之间配置直接通信接口,所述定位功能实体通过该直接通信接口向无线接入网RAN设备发送第一请求消息,所述第一请求消息用于请求位置相关信息;定位功能实体接收RAN设备发送的针对第一请求消息的第一回复消息,如此,通过配置定位功能实体与RAN设备之间的直接通信接口,使得定位功能实体能够直接调用RAN设备的定位服务,在定位功能实体与RAN设备之间传递定位消息,从而降低定位时延。
可选地,所述第一请求消息包括下述中任意一项或者多项:
定位消息;
所述定位消息的消息类型;
关联标识,所述关联标识用于识别RAN设备所发送的回复消息中与所述第一请求消息关联的第一回复消息;
终端的第一标识,所述第一标识为RAN设备为终端分配的、用于标识该终端。
可选地,定位消息为向终端发送的第一定位消息,或者,定位消息为向RAN设备发送的第三定位消息。
需要说明的是,若定位消息为向终端发送的第一定位消息,则后续执行用户设备(User Equipment,UE)辅助和基于UE的定位过程。
若定位消息为向RAN设备发送的第三定位消息,则后续执行网络辅助的 定位过程。
其中,消息类型用于指示定位消息的类型。其中,定位消息的类型包括下述中的一者:
类型1:向终端发送的第一定位消息。
类型2:向RAN设备的第三定位消息。
需要说明的是,RAN设备可根据第一请求消息中包含的定位消息的消息类型确定具体由哪个设备来处理该定位消息。具体的,若定位消息的消息类型为类型1,则由RAN设备将定位消息(第一定位消息)发送给终端,由终端处理该定位消息,即根据该定位消息,执行UE辅助和基于UE的定位过程。
若定位消息的消息类型为类型2,则由RAN设备自己处理该定位消息(第三定位消息),即该RAN设备执行网络辅助定位过程。
可选地,第一定位消息包括下行定位消息(Downlink Positioning message)或者位置服务周期性调用请求(LCS Periodic-Triggerd Invoke Request)消息。
可选地,第三定位消息包括网络定位消息(Network Positioning message)或者预先约定的消息。
作为一可选的实现方式,本公开实施例的方法步骤101,所述定位功能实体通过所述直接通信接口向无线接入网RAN设备发送第一请求消息,包括:
接收移动性功能实体发送的位置请求消息,所述位置请求消息用于请求终端的位置,所述位置请求消息中携带与终端相关的信息;
根据与终端相关的信息,通过所述直接通信接口向所述信息对应的无线接入网设备发送第一请求消息,所述第一请求消息中携带终端的第一标识。
需要说明的是,本公开实施例中涉及的移动性功能实体可以是5G网络中的AMF实体,4G网络中的移动性管理实体(Mobility Management Entity,MME),或者是6G网络中管理UE移动性的功能实体,这里不做具体限定。
以5G网络中的LMF实体为例:
LMF实体接收AMF实体发送的决定位置请求消息,具体的是,接收AMF实体发送的确定位置请求(Nlmf_Location_DetermineLocation Request)消息。
这里,LMF实体之所以能够接收AMF实体发送的决定位置请求消息,在于AMF实体基于下述步骤选择了该LMF实体:
AMF实体在接收到网关移动位置中心(Gateway Mobile Location Center,GMLC)发送的Namf_位置_提供位置信息请求(Namf_Location_ProvidePositioningInfo Request)消息,或者接收到发送的上行(Uplink,UL)非接入服务(Non Access Stratum,NAS)传输(TRANSPORT)移动初始定位流程(Mobile Originating Location Request,MO-LR)后,执行LMF选择。
具体的,AMF实体根据数据网络接入标识符(Data Network Access Identifier,DNAI)、单网络切片选择辅助信息(Single Network Slice Selection Assistance Information,S-NSSAI)、应用标识符、位置服务客户端(Location Services client,LCS Client)标识符等信息,通过查找网络存储功能(Network Repository Function,NRF)实体,获取LMF实体的信息。
这里,DNAI、S-NSSAI应用标识符、LCS Client标识符等信息可以是UE或者GMLC提供的;也可以是AMF实体根据GMLC或者UE提供的信息和本地配置信息决定的,例如AMF根据UE提供的业务类型/客户类型决定S-NSSAI;或者AMF根据GMLC提供的业务类型/客户类型决定S-NSSAI。
作为另一可选的实现方式,本公开实施例的方法步骤101,所述定位功能实体通过所述直接通信接口向无线接入网RAN设备发送第一请求消息,可包括:
获取为终端提供服务的RAN设备的信息和/或终端的第一标识;
本步骤中,RAN设备的信息包括唯一能够标识RAN设备的标识,比如可以是RAN设备的IP地址,或者是RAN设备的身份标识号(Identity Document,ID)。
