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)相对另一个UE(即参考UE)的方向和/或位置。
侧行链路(Sidelink，SL)定位是使用PC5定位UE。
参考(Reference)UE：在基于测距的服务和侧行链路定位中确定参考平面和参考方向的UE。
目标(Target)UE：在基于测距和侧行链路定位的服务中，相对于参考UE的参考平面、参考方向和/或位置，被测量距离、方向和/或位置的UE。
辅助(Assistant)UE：当参考UE与目标UE之间的直接测距/侧行链路定位不被支持时，为测距/侧行链路定位提供辅助的UE。
定位(Located)UE：使用基于Uu的定位，获取或能够获取其位置的UE。定位UE可用于使用侧行链路定位确定目标UE的位置。
位置服务(Location Server)UE：用于代替LMF(Location Management Function定位管理功能)提供位置服务功能，通过侧行链路进行侧行链路定位和测距的UE。它需要与目标UE、参考UE、辅助UE和定位UE进行交互，以便计算目标UE的位置。
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是不同场景下的UE提供测距服务的示意图。其中，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。如果许可频段用于测距，则应完全由运营商控制。
两个UE之间的测距服务可以由第三方UE触发并向第三方UE开放。
第三方UE可以通过直接通信或5GC(5th Generation Core，5G核心网)网络被测距/侧行链路定位的UE发送请求，并接收相应结果。
在5GC中，SUPI用于识别UE以存储和检索其签约数据、配置文件和上下文数据，并用于UE相关的信令或数据流的路由；但是，参考UE的SUPI值和目标UE的SUPI值不能暴露给第三方UE。
对于第三方UE必须通过5GC向目标UE或参考UE发送测距/侧行链路定位服务请求的情况，如何在5GC中理解和使用第三方UE提供的目标UE的标识和参考UE的标识是一个亟需解决的问题。
图3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控制面网元执行，如图3所示，所述方法包括：

所述第三方终端可以是不同于所述目标终端和所述参考终端的终端。第三方终端可以请求获取所述目标终端和所述参考终端的测距和/或侧行链路定位结果。
例如作为第三方终端的某一车辆若需要获取该车辆附近的两个车辆之间的相对位置，则该车辆可以向通过服务于该车辆的AMF发起服务请求，以请求获取所述两个车辆之间的相对位置。
其中，服务于所述第三方终端的AMF是指第三方终端的服务AMF。
在一些示例中，服务于第三方终端的AMF和服务于目标终端的AMF以及服务于参考终端的AMF可以是相同的，也可以不同。
在另一些示例中，服务于第三方终端的AMF和服务于目标终端的AMF可以相同，服务于第三方终端的AMF与服务于参考终端的AMF不同。

终端的SUPI是无线通信系统中的网络运营商为每个终端分配的一个唯一的标识符。
所述控制面网元可以预先建立终端的一个或多个应用层标识与该终端的SUPI之间的映射关系。
所述终端的SUPI可以用于处理与所述目标终端和所述参考终端的测距和/或侧行链路定位相关的信令、数据流或用户信息。

本公开实施例提供的信息处理方法，通过控制面网元接收到服务于第三方终端的AMF网元发送的查询请求，并根据终端的应用层标识与SUPI之间的映射关系，向所述AMF网元返回AMF请求查询的所述目标终端的SUPI和所述参考终端的SUPI。如此，在第三方终端必须通过5GC向目标终端或参考终端发送测距服务请求的情况下，能够通过所述目标终端的SUPI和所述参考终端的SUPI用于理解和使用第三方终端提供的目标终端的标识和参考终端的标识，实现处理与所述目标终端和所述参考终端的测距和/或侧行链路定位相关的信令和数据。
在一个实施例中，同一个终端的应用层标识与SUPI具有一对一的映射关系或多对一的映射关系。
终端的用于测距和/或侧行链路定位的应用层标识可以为一个或多个。针对一个终端，若终端注册到控制面网元的应用层标识仅一个时，控制面网元可以对终端的该应用层标识该终端的SUPI建立一对一的映射关系。若该终端注册到控制面网元的应用层标识为多个时，控制面网元可以对该终端的该应用层标识该终端的SUPI建立多对一的映射关系。
在一个实施例中，所述向控制面网元发送查询请求之前，所述方法还包括：
接收所述第三方终端发送的第一服务请求；其中，所述第一服务请求包含：所述目标终端的应用层标识和所述参考终端的应用层标识。
本实施例中，第三方终端若需要获取所述目标终端和所述参考终端的测距和/或侧行链路定位结果，在第三方终端通过PC5未发现到目标终端和参考终端的情况下，第三方终端可以基于5GC网络向通过服务于所述第三方终端的AMF发起第一服务请求，以请求获取所述目标终端和所述参考终端的测距和/或侧行链路定位结果。
在一个实施例中，所述方法还包括：
向服务于所述目标终端或所述参考终端的AMF网元发送第二服务请求；其中，所述第二服务请求中包含：所述目标终端的应用层标识、所述参考终端的应用层标识、所述目标终端的SUPI和所述参考终端的SUPI。
服务于所述第三方终端的AMF网元通过检索UDM(Unified Data Management，统一数据管理)网元以获取目标终端或者参考终端的服务AMF的地址，根据获取到的目标终端或者参考终端的服务AMF网元的地址，向目标终端或者参考终端的服务AMF发送第二服务请求。第二服务请求中包含：目标终端的应用层标识、参考终端的应用层标识、所述目标终端的SUPI和所述参考终端的SUPI。
这里，服务于所述目标终端的AMF网元即为目标终端的服务AMF网元。服务于所述参考终端的AMF网元即为参考终端的服务AMF网元。
在一些示例中，所述目标终端的服务AMF网元和所述参考终端的服务AMF网元可以为同一个AMF网元，也可以为不同AMF网元。
在一个实施例中，所述方法还包括：
接收服务于所述目标终端或所述参考终端的AMF返回的服务请求响应；
将所述服务请求响应转发至所述第三方终端；其中，所述服务请求响应中包含：被允许提供给所述第三方终端的所述目标终端和所述参考终端的测距和/或侧链路定位结果。
所述目标终端或所述参考终端的服务AMF接收到所述第二服务请求后，基于所述第二服务请求中包含的目标终端的SUPI和参考终端的SUPI检查目标终端的隐私信息和参考终端的隐私信息，以确定是否允许第三方终端获取目标终端和参考终端的测距和/或侧行链路定位信息。
若目标终端的隐私信息和参考终端的隐私信息指示允许第三方终端获取目标终端和参考终端的测距和/或侧行链路定位信息，所述目标终端或所述参考终端的服务AMF可以通过NAS (Non-Access-Stratum，非接入层)向所述目标终端或所述参考终端发送测距和/或侧行链路定位服务请求，包括目标终端的应用层标识和参考终端的应用层标识。
目标终端与参考终端之间执行测距和/或侧行链路定位过程，以触发测量和计算结果，并将测量和计算结果返回给所述目标终端或所述参考终端的服务AMF，以使得所述目标终端或所述参考终端的服务AMF向第三方终端的服务AMF返回服务请求响应。服务请求响应中包含：被允许提供给所述第三方终端的所述目标终端和所述参考终端的测距和/或侧链路定位结果。
第三方终端的服务AMF将所述服务请求响应转发给所述第三方终端。
需要说明的是，当服务于所述第三方终端的AMF网元与服务于所述目标终端或所述参考终端的AMF网元相同时，所述服务于所述第三方终端的AMF网元向服务于所述目标终端或所述参考终端的AMF网元发送第二服务请求，以及接收服务于所述目标终端或所述参考终端的AMF返回的服务请求响应之间的步骤可以跳过执行。
在一个实施例中，所述控制面网元包括：
GMLC网元；
或者，
NEF网元；
或者，
PCF网元。
本公开实施例中，用于测距和/或侧行链路定位的终端的应用层标识与SUPI之间的映射关系可以存储于GMLC网元、NEF网元或者PCF网元。
为了进一步解释本公开任意实施例，以下提供几个具体实施例。
应用层ID，是特定应用程序上下文中的标识符，用于识别支持测距/SL定位的UE，被第三方UE用来识别服务请求中的目标UE和参考UE。
5GC NF(例如GMLC或NEF)维护UE的应用层ID和SUPI之间的映射表。该映射表可以由运营商预先配置，或者由UE在注册期间或UE策略关联建立期间注册。对于后一种情况，应用层ID注册有2个选项：
选项1：在注册期间，UE将测距/SL定位应用层ID作为部分“5GMM能力”信息包含在注册请求消息中。如果收到应用层ID，AMF将应用层ID与UE的SUPI一起注册到5GC NF中，5GC NF(例如GMLC或NEF)维护应用层ID和UE的SUPI之间的映射表以供以后使用(此UE是测距/SL定位请求的目标UE或参考UE)。
选项2：在注册期间，UE将包含测距/SL定位应用层ID的UE策略容器发送至PCF。如果收到应用层ID，PCF将应用层ID与UE的SUPI一起注册到5GC NF中，5GC NF(例如GMLC或NEF)维护应用层ID和UE的SUPI之间的映射表以供以后使用(此UE是测距/SL定位请求的目标UE或参考UE)。
对于第三方UE必须通过5GC向目标UE或者参考UE发送测距和/或SL定位请求的情况，当 AMF收到第三方UE的测距/SL定位请求时，它会查询5GC NF维护的映射表，根据测距和/或SL定位请求中包含的应用层ID，检索被测距/SL定位的UE的SUPI。
下面，以GMLC作为控制面网元进行示例说明。
如图5所示，本公开实施例提供一种信息处理方法，该方法由第三方UE发起基于网络的测距和/或SL定位。
1.向UE1和UE2提供服务授权策略/参数。
2.第三方UE通过PC5未发现到UE1和UE2。第三方UE向其服务AMF即AMF3发送测距/SL定位服务请求，包括UE1和UE2的应用层ID、结果内容(距离或角度或距离和角度)和所需的QoS(Quality of Service，服务质量)等。
3.AMF3根据应用层ID向GMLC查询UE1的SUPI和UE2的SUPI。
4.AMF3检索UDM以获取UE1或者UE2的服务AMF。如果检索到UE1的服务AMF的地址，即AMF1，则AMF3向AMF1发送测距和/或SL定位服务请求，包括UE1的SUPI值和UE2的SUPI值以及它们的应用层ID。
注1：AMF3也可能从UDM中检索到UE2的服务AMF的地址。在此解决方案中，AMF1为接收AMF发送的服务请求的AMF。
5.AMF1基于UE1的SUPI和UE2的SUPI检查UE1和UE2的隐私信息，以确定是否允许第三方UE拥有UE1和UE2的测距和/或SL定位信息。
6.AMF1通过NAS向UE1发送测距和/或SL定位服务请求，包括UE1的应用层ID和UE2的应用层ID。
7.UE1向UE2发起测距和/或SL定位过程，以触发测量和计算结果。
注2：测距和/或SL定位过程包括：测距/SL定位发现和服务操作。是否涉及DDNMF取决于在KI#3下开发的解决方案。
8.UE1将包含测距和/或定位结果的响应发送给AMF1。
9.AMF1将包含测距和/或SL定位结果的响应转发给AMF3。
10.AMF3将包含测距和/或SL定位结果的响应转发给第三方UE。
应当理解，这里以第三方UE服务的AMF3与UE1或者UE2的服务AMF1不同的情况进行说明，当AMF3与AMF1相同时，可以省略AMF1将包含测距和/或SL定位结果的响应转发给AMF3的步骤。
如图6所示，本公开实施例提供一种信息处理方法，该方法可以通过AMF发起测距/SL定位应用层ID与SUPI之间的注册流程。
1.AMF接收来自UE的注册请求消息，该注册请求消息中包含作为部分“5GMM能力”的测距/SL定位应用层ID。
2.AMF将UE的SUPI与测距和/或SL定位应用层ID的关系注册到GMLC。
3.GMLC存储UE的SUPI与测距和/或SL定位应用层ID的关系，并响应AMF。
注：也可以在上述过程中将GMLC替换为NEF。
如图7所示，本公开实施例提供一种信息处理方法，该方法可以通过PCF发起测距/SL定位应用层ID与SUPI之间的注册流程。
1.在UE策略关联建立期间，PCF接收Npcf_UEPolicyControl创建请求，该请求携带的UE策略容器中包含有UE的测距和/或SL定位应用层ID。
2.PCF将UE的SUPI与测距和/或SL定位应用层ID的关系注册到GMLC中。
3.GMLC存储UE的SUPI与测距和/或SL定位应用层ID的关系，并响应PCF。
注：也可以在上述过程中将GMLC替换为NEF。
如图8所示，本公开实施例提供一种信息处理方法，该方法由第三方UE发起的基于PC5的测距/SL定位过程。
1.向UE1和UE2提供服务授权策略/参数。
2.第三方UE启动设备发现程序以发现UE1或UE2，且成功发现其中一个，例如UE1。以下情况下跳过此步骤：
-第三方UE和UE1之间存在通信
-第三方UE和UE1是同一个UE，即服务请求是从UE1的上层发起的。
注1：也有可能发现UE2。在该方案中，UE1表示第三方UE决定向其发送服务请求的UE。
注2：设备发现遵循V2X(vehicle to everything，即车对外界的信息交换)或ProSe(Proximity Services)的设备发现过程或测距/SL定位设备发现过程。
3.第三方UE向UE1发送测距/SL定位服务请求，包括UE1的应用层ID和UE2的应用层ID、结果内容(距离、角度或两者)和所需的QoS等。
4.UE1向UE2发起测距/SL定位过程，以触发测量和结果计算。UE1的应用层ID和UE2的应用层ID用于UE1和UE2在PC5上的通信。
注3：测距/SL定位过程包括测距/SL定位发现和服务操作。是否涉及DDNMF取决于在KI#3下开发的解决方案。
5.UE1将包含UE1和UE2的测距/SL定位结果的响应发送给第三方UE。
