其中,接入网设备12可以是4G系统中采用的演进型接入设备(eNB)。或者,接入网设备12也可以是5G系统中采用集中分布式架构的接入设备(gNB)。当接入网设备12采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本公开实施例对接入网设备12的具体实现方式不加以限定。
接入网设备12和UE 11之间可以通过无线空口建立无线连接。在不同的实施方式中,该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口;或者,该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口,比如该无线空口是新空口;或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
UE 11之间还可以建立E2E(End to End,端到端)或D2D(device to device,终端到终端)连接。比如车联网通信(vehicle to everything,V2X)中的V2V(vehicle to vehicle,车对车)通信、V2I(vehicle to Infrastructure,车对路边设备)通信和V2P(vehicle to pedestrian,车对人)通信等场景。

为了便于本领域内技术人员理解,本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然,本领域内技术人员可以理解,本公开实施例提供的多个实施例,可以被单独执行,也可以与本公开实施例中其他实施例的方法结合后一起被执行,还可以单独或结合后与其他相关技术中的一些方法一起被执行;本公开实施例并不对此作出限定。
以下对本公开实施例的部分用语进行解释说明,以便于本领域技术人员理解功能。
测距是指通过PC5接口确定两个或多个UE之间的距离和/或一个UE(即目标UE)相对于另一个UE(即参考UE)的方位。
侧行链路(Sidelink,SL)定位是利用PC5对UE进行定位,以获取绝对位置、相对位置或测距信息。
SL参考(Reference)UE:该UE支持目标UE的定位,例如,通过使用SL发送和/或接收参考信号进行定位、提供与定位相关的信息等。在一些情形下,SL参考UE可以被理解为“锚定(Anchor)UE”。
目标(Target)UE:在基于测距和/或侧行链路定位的服务中,在使用侧行链路的一个或多个SL参考UE的支持下,被测量距离、方位和/或位置的UE。
辅助(Assistant)UE:当SL参考UE和目标UE之间的直接测距和/或侧行链路定位不能被支持时,该UE通过PC5支持SL参考UE和目标UE之间的测距和/或侧行链路定位。确定辅助UE和SL参考UE之间以及辅助UE和目标UE之间的测距和/或侧行链路定位的测量/结果,以用于得出 目标UE和SL参考UE之间的测距和/或侧行链路定位的结果。
定位(Located)UE:使用基于Uu的定位,获取或能够获取其位置的SL参考UE。定位UE可用于使用侧行链路定位确定目标UE的位置。
SL定位服务端UE:提供位置计算的UE,用于基于SL定位和/或测距的服务。它需要与PC5上的其他UE交互,以计算目标UE的位置。如果支持位置计算,目标UE或SL参考UE可以充当SL定位服务端UE。
SL定位客户端UE:除SL参考UE和目标UE之外的第三方UE,它代表驻留在其上的应用程序发起测距和/或SL定位服务请求。
SL定位客户端UE不必具有支持测距和/或SL定位能力,但SL定位客户端UE与SL参考UE和目标UE之间的通信必须通过PC5或通过5GC建立,以用于传输服务请求或结果。
定位(Positioning):该功能可检测例如移动终端的地理位置以及可选地,移动终端的速度。
网络辅助操作:在5GC NF(Network Function,网络功能)参与下进行测距和/或SL定位操作,用于服务请求处理和结果计算。
UE-only操作:进行测距和/或SL定位的操作,其中由UE执行服务请求处理和结果计算。对于UE-only操作,UE之间的通信是通过PC5进行的。
相对位置(Relative position):相对于其他网元或相对于其他UE的UE位置估计。
应用层ID(Application Layer ID):用于在特定应用的上下文中识别被使能测距和/或SL定位的UE,且用于SL定位客户端UE在服务请求中识别目标UE和SL参考UE。
无论是否有5G覆盖,均可支持测距和侧行链路定位服务。图2示出了有5G覆盖或有部分5G覆盖或没有5G覆盖不同场景下的UE提供测距服务。若许可频段用于测距,则应完全由运营商控制。
SL定位客户端UE发起服务请求,服务请求中包括目标UE的标识和SL参考UE的标识。
在5GC中,SUPI用于识别UE以存储和检索其订阅数据、配置文件和上下文数据,并将信令或流量路由到UE;但是,SL参考UE和目标UE的SUPI值不能暴露给SL定位客户端UE。
对于SL定位客户端UE必须通过5GC向目标UE或参考UE发送测距和/或SL定位请求的情况,UE可以在初始注册到网络时,将其应用层ID注册到5GC NF上,该5GC NF用于维护UE的一个或多个应用层ID与SUPI之间的映射关系,从而可以利用UE的应用层ID推导出UE的SUPI。
如图3a所示,为通过AMF发起的测距和/或SL定位应用层ID的注册流程,包括:
1、AMF接收测距和/或SL定位应用层ID。示例性地,该测距和/或SL定位应用层ID可以作为部分“5GMM能力(5GS mobility management capability,5G系统移动管理能力)”包含在UE的注册请求消息中。
2、AMF将UE的测距和/或SL定位应用层ID与SUPI的关系注册到GMLC中。
3、GMLC存储UE的测距和/或SL定位应用层ID与SUPI的关系,并响应AMF。
注:GMLC可以在上述注册过程中替换为NEF。
如图3b所示,为通过PCF发起的测距和/或SL定位应用层ID的注册流程,包括:
1、在UE策略关联建立期间,PCF接收包含UE的测距和/或SL定位应用层ID的UE策略容器,该UE策略容器包含在Npcf_UEPolicyControl创建请求中。
2、PCF将UE的测距和/或SL定位应用层ID与SUPI的关系注册到GMLC中;
3、GMLC存储UE测距和/或SL定位应用层ID与SUPI的关系,并响应PCF。
注:GMLC可以在上述注册过程中替换为NEF。
然而,在UE初始注册到网络时,一些应用层ID仍然是未知的。只有在一个应用程序被使用过之后,操作系统才能获取这个应用程序的应用层ID。对于UE新安装的测距和/或SL定位应用程序或安装后从未使用过的测距和/或SL定位应用程序,在UE初始注册时这些应用程序的应用层ID可能不可用。
因此,需要进一步研究在UE初始网络注册到5GC NF(例如GMLC、NEF等)后,如何注册UE可用的应用层ID。
图4是根据一示例性实施例示出的一种信息处理方法的流程图。所述信息处理方法由第一核心网设备执行,如图4所示,所述方法可以包括:
S101:接收UE在完成初始注册之后发送的应用层标识;其中,所述应用层标识,用于与所述UE的SUPI建立映射关系。

所述UE在完成所述初始注册之后更新的应用层标识。
在一些示例中,UE在完成初始注册之前未生成有应用层标识,若UE在完成初始注册之后生成有应用层标识,UE可以向所述第一核心网设备发送所述UE完成初始注册之后生成的应用层标识。
在一些示例中,UE在完成初始注册之前通过第一核心网设备向网络侧注册过所述UE的应用层标识,若所述UE在完成初始注册之后增加有应用层标识,所述UE可以向所述第一核心网设备发送所述UE完成初始注册之后增加的应用层标识。

在一些示例中,所述UE的应用层标识可以用于供所述第一核心网设备发送至第二核心网设备,以使第二核心网设备建立所述UE的应用层标识与所述UE的SUPI之间的映射关系。这里,第二核心网设备不同于第一核心网设备,例如所述第二核心网设备可以为PCF、GMLC或NEF等。
在一些示例中,同一个UE的应用层标识与SUPI具有一对一的映射关系或多对一的映射关系。
在一些示例中,所述映射关系可以采用多种形式进行保存,例如,配置文件、表格、数据库等,但并不限于此。
本实施例中,所述UE的应用层标识与SUPI具有的映射关系,也可以描述为“对应关系”或“关联关系”。
本公开实施例提供一种信息处理方法,通过第一核心网设备接收UE在完成初始注册之后发送的应用层标识,可以将UE在完成初始注册后发送的应用层标识与所述UE的SUPI建立映射关系。如此,UE在完成初始注册之后获得的应用层标识或者在完成初始注册之后有更新的应用层标识,都会上报给网络侧设备,这样能够减少网络侧设备仅仅依赖UE初始注册提交的应用层标识和UE的SUPI建立映射关系而导致相关业务受限的问题。
在一些实施例中,所述方法可以包括:
第一核心网设备接收所述UE在初始注册流程中和/或在完成初始注册之后发送的所述UE的应用层标识。如此,第一核心网设备可以在UE的初始注册流程中和/或完成初始注册之后接收到UE发送的应用层ID。
由于第一核心网设备在UE完成初始注册之后依然可以接收UE发送的应用层ID,则第一核心网设备可以获取到UE最新的可用应用层ID。
在一个实施例中,上述步骤S101中,所述接收UE在完成初始注册之后发送的应用层标识,可以包括:
接收包含所述应用层标识的注册更新消息;和/或,
接收包含所述应用层标识的UE策略容器。
在一些示例中,包含所述应用层标识的注册更新消息,可以是所述UE的周期性注册更新消息或非周期性注册更新消息。
例如,所述注册请求消息可以是UE在完成初始注册之后发送的定期更新注册的注册请求消息。
又例如,所述注册请求消息可以是UE在完成初始注册之后,响应于特定事件发送的非周期性注册更新消息。这里,特定事件可以包括:所述UE完成初始注册之后生成应用层标识、增加应用层标识和/或更新应用层标识。
在一些示例中,包含所述应用层标识的所述UE策略容器,可以是所述UE完成初始注册之后,在所述UE触发的V2X策略配置过程或所述UE触发的ProSe策略配置过程中发送的。
在一个实施例中,如图5所示,所述方法还可以包括:
S201:向第二核心网设备发送所述UE的应用层标识。
在一些示例中,所述第二核心网设备包括以下至少之一:
策略控制功能(PCF);
网络功能(NF)。
在一些示例中,第一核心网设备在接收到包含所述UE的应用层标识的注册更新消息时,可以根据所述注册更新消息,将所述UE的应用层标识与SUPI发给所述NF,由所述NF建立所述UE的应用层标识和SUPI之间的映射关系。
在另一些示例中,第一核心网设备在接收到包含所述应用层标识的注册更新消息时,可以将UE的应用层标识与SUPI发给所述PCF。例如,基于所述PCF的订阅请求,所述第一核心网设备将UE的应用层标识与SUPI发给所述PCF。
在又一些示例中,所述第一核心网设备在接收到包含所述应用层标识的UE策略容器时,可以将所述UE策略容器转发或者透传给所述PCF。
在所述PCF支持维护所述UE的应用层标识与SUPI之间的映射关系的情况下,可以由所述PCF建立所述UE的应用层标识和SUPI之间的映射关系。
在所述PCF不支持维护所述UE的应用层标识与SUPI之间的映射关系的情况下,可以通过所述PCF将所述UE的应用层标识和SUPI发送给所述NF,由所述NF建立UE的应用层标识和SUPI之间的映射关系。
在一些示例中,所述NF包括以下至少之一:
网关移动位置中心(GMLC);
网络开放功能(NEF);
统一数据管理功能(UDM);
直接发现名称管理功能(DDNMF)。
本实施例中,若接收所述UE在完成初始注册之后发送的应用层标识的接收端为所述GMLC、NEF、UDM和DDNMF中的至少一个,则所述UE的应用层标识与SUPI之间的映射关系可以由GMLC、NEF、UDM和DDNMF中的至少一个建立。
在一个实施例中,上述步骤S201中,所述向第二核心网设备发送所述UE的应用层标识,包括:
基于所述PCF的订阅请求,向所述PCF发送所述UE的应用层标识;其中,所述订阅请求,用于向所述第一核心网设备订阅所述UE的应用层标识的接收事件。
本实施例中,PCF可以通过订阅等方式从第一核心网设备获取所述UE在完成初始注册之后发送给第一核心网设备的应用层标识。
第一核心网设备根据PCF的订阅请求,确认是否执行订阅事件上报。当第一核心网设备接收到所述UE在完成初始注册之后发送的应用层标识时,则会执行订阅事件上报,即向所述PCF发送所述UE的应用层标识。
在一个实施例中,上述步骤S201中,所述向第二核心网设备发送所述UE的应用层标识,包括:
在所述UE被授权成为测距和/或侧行链路定位的目标UE或参考UE的情况下,向第二核心网设备发送所述UE的应用层标识。
在一些示例中,第一核心网设备可以根据所述UE的签约数据,确定所述UE是否被授权成为测距和/或侧行链路定位的目标UE或参考UE。
例如,第一核心网设备可以通过用户签约数据获取服务消息向UDM发送查询请求,并根据UMD返回的查询响应,确定所述UE是否被授权成为测距和/或侧行链路定位的目标UE或参考UE。这里,用户签约数据获取服务消息可以为Nudm_SDM_GET。
在另一些示例中,所述第一核心网设备可以根据来自所述PCF的订阅请求,确定所述UE是否被授权成为测距和/或侧行链路定位的目标UE或参考UE。其中,所述订阅请求中携带有被授权成为测距和/或侧行链路定位的目标UE或参考UE的UE的SUPI。
在一些示例中,在所述UE未被授权成为测距和/或侧行链路定位的目标UE或参考UE的情况下,第一核心网设备不向第二核心网设备发送所述UE的应用层标识。
在一个实施例中,所述应用层标识包括:所述UE的测距和/或侧行链路定位的应用层标识。
本实施例中,所述UE的应用层标识包括所述UE的测距和/或侧行链路定位的应用层标识,如此网络侧接收到所述UE的测距和/或侧行链路定位的应用层标识时,可以建立所述UE的测距和/或侧行链路定位的应用层标识与所述UE的SUPI之间的映射关系,这样在UE的SUPI不能被透露给第三方UE的情况下,网络侧可以通过UE的应用层标识利用该预设关系确定到所述UE的SUPI,从而实现处理与所述UE的测距和/或SL定位相关的信令和数据。
图6是根据一示例性实施例示出的一种信息处理方法的流程图。所述信息处理方法由第二核心网设备执行,如图6所示,所述方法可以包括:

选项1:AMF注册应用层ID;
当测距和/或SL定位的新应用层ID在UE可用时,UE将它们包含在定期注册更新的注册请求消息中。AMF若收到UE的应用层ID,则将其与UE的SUPI一起注册到5GC NF(例如NEF、GMLC、PCF、UDM或DDNMF)中,该5GC NF可用于维护UE的应用层ID和SUPI之间的映射表以供后续使用(例如,该UE是测距和/或SL定位请求的目标UE或参考UE)。
选项2:PCF注册应用层ID,包括:
2-A:基于PCF订阅,当AMF接收到测距和/或SL定位应用层ID(s)时,AMF将测距和/或SL定位应用层ID(s)报告给PCF,PCF将测距和/或SL定位应用层ID(s)与UE的SUPI一起注册到5GC NF(例如NEF、GMLC、PCF、UDM或DDNMF)中,该5GC NF可用于维护UE的应用层ID和SUPI之间的映射表以供后续使用(例如,该UE是测距和/或SL定位请求的目标UE或参考UE)。
在UE策略关联过程中,PCF需要为UE向AMF订阅“测距和/或SL定位应用层ID(s)接收”事件,该UE是被授权成为测距和/或SL定位的目标UE或SL参考UE的UE。
2-B:在UE触发的V2X策略配置过程或UE触发的ProSe策略配置过程中,UE将测距和/或SL定位应用层ID包含在UE策略容器中发送给PCF。如果收到UE的应用层ID,PCF将其与UE的SUPI一起注册到5GC NF(例如NEF、GMLC、PCF、UDM或DDNMF)中,该5GC NF可用于维护UE的应用层ID和SUPI之间的映射表以供后续使用(例如,该UE是测距和/或SL定位请求的目标UE或参考UE)。
