为了方便理解，下面对本公开的术语进行解释。
1、基于测距的服务和侧链定位
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)与另一UE(即参考UE)之间的方向。Sidelink定位是指使用PC5对UE进行定位。基于测距的服务和侧链路定位包括距离测量、方向测量或两者。
基于网络的操作：涉及5GC NF的测距/侧链路定位操作，用于服务请求处理和结果计算。
UE-only操作：测距/侧链路定位操作，其中服务请求处理和结果计算由UE执行。
2、测距角色(Ranging Role)
定位UE：位置已知或能够使用基于Uu的定位获知的SL参考UE。定位UE可用于使用侧链路定位来确定目标UE的位置。
SL参考UE：支持目标UE定位的UE，例如：通过使用侧链路发送和/或接收用于定位的参考信号、提供定位相关信息等。示例性的，SL参考UE也可以被称为“锚点UE(Anchor UE)”。
SL定位客户端UE：除SL参考UE和目标UE之外的第三方UE，其代表驻留在其上的应用程序发起测距/侧链路定位服务请求。
其中，SL定位客户端UE不必支持测距/侧链路定位功能，但必须通过PC5或通过5GC建立SL定位客户端UE和SL参考UE/目标UE之间的通信以进行传输服务请求和结果。
SL定位服务器UE：UE为基于侧链定位和测距的服务提供方法确定、辅助数据分发和/或位置计算功能。它根据需要通过PC5与其他UE交互，以确定测距/SL位置方法、分发辅助数据并计算目标UE的位置。如果支持任何功能，则目标UE或SL参考UE可以充当SL定位服务器UE。
目标UE：在基于测距的服务和Sidelink定位中使用Sidelink在一个或多个SL参考UE的支持下测量其距离、方向和/或位置的UE。
3、无需NAS连接的UE基于网络的SL定位
当目标UE由于目标UE超出覆盖范围而无法与AMF建立NAS连接，并且至少一个发现的定位UE可以为5GC-MO-LR建立NAS连接时，应用以下原则：
注1：5GC-MT-LR不适用于本版本的规范。
-目标UE执行定位UE的发现和选择。
-目标UE和定位UE执行测距/SL定位。
-目标UE选择至少一个可以使用SL-MO-LR服务进行SL定位的定位UE。
-目标UE可以将其测距测量数据/结果发送到定位的UE。
-可以建立NAS连接的每个定位UE可以通过定位UE的服务AMF向LMF报告测距/SL定位测量数据或结果以及从目标UE到LMF的路由标识符。这可以包括从目标UE接收的测距测量数据/结果。LPP消息的端点是LMF和定位的UE。
注2：路由标识符指示管理目标UE定位的LMF，并且还用于协助LMF识别目标UE定位。
在一些实施例中，LMF可以使用接收到的信息(即具有相同路由标识符的测距/SL定位测量或估计结果)和定位UE的位置来计算目标UE的位置，并通过定位UE提供结果位置到目标UE。
在一些实施例中，如果LMF基于相同的路由标识符知道与同一目标UE相关联的多个定位UE，则它可以使用来自这些定位UE的所有信息来执行计算。
在一些实施例中，LMF可以使用接收到的信息(即测距/SL定位测量数据/结果和相同的路由标识符)和定位UE的位置来计算目标UE的位置，并通过定位UE提供结果位置向目标UE发起5GC-MO-LR过程。如果LMF具有目标UE上下文，则LMF可以通过GMLC向LCS客户端或AF提供结果位置。如果UE上下文被删除，则无法执行此功能。
示例性的，在一些实施例中，如果目标UE选择了多个定位UE，则目标UE可以将路由ID发送给定位UE，以确保定位UE可以分别向LMF报告测距/SL定位测量数据或结果，这由来自目标UE的路由ID指示。
图2为本公开实施例所提供的一种涉及LMF的SL-MO-LR过程的交互示意图，其中，图2说明了使终端能够在终端1的服务公共陆地移动网(Public Land Mobile Network，PLMN)中的LMF的帮助下使用一个或多个其他终端来获得侧链定位/测距位置结果的过程。测距/SL定位结果可能包括绝对位置、相对位置或距离和方向，具体取决于服务请求。如果目标终端决定发起SL-MO-LR过程，则其在服务请求中包括一个或多个侧链(Sindlink，SL)参考终端/定位终端。其中，终端1处于覆盖范围内并且向服务PLMN注册。终端2至n可以在覆盖范围内，也可以不在覆盖范围之内，并且如果在覆盖范围中，则可以向与终端1相同的服务PLMN注册，也可以不对其注册。
如图2所示，该方法包括如下步骤1-步骤23：
步骤1、SL-MO-LR(侧行链路终端发起位置请求)的过程和信令可用于在覆盖时向终端1至n提供测距/SL定位服务授权和策略/参数提供。
注：如果接收到仅终端操作的指示，则执行测距/侧链定位控制程序(或流程)。
步骤2、基于服务请求的触发(例如，从应用层接收的)，其包括终端1/.../终端n，为测距/SL定位执行终端发现：
如果终端1是目标终端，则终端1发现终端2到n；
如果终端1是定位终端，则目标终端(即，终端2至n中的一个)发现终端1(以及终端2至n的集合中的其他定位终端)。
步骤3、在终端1至n之间建立安全的群播和/或单播链路，以使终端1能够在PC5-U参考点上与终端2至n中的每一个交换测距和侧链定位协议(RSPP)消息，并且可能使终端2至n能够在彼此之间的PC5-U上交换RSPP。
注：RSPP信号的安全方面需要由SA WG3定义或同意。
步骤4、终端1和终端2至n可以通过PC5进行通信，以授权测距/SL定位并在需要时接收QoS参数。每个终端根据在步骤1接收到的任何服务授权和策略/参数供应来验证允许测距/SL定位，包括测距/SL的定位结果是否可以被传送到位置服务LCS客户端或AF(如果使用的话)。还可以基于服务请求中的QoS要求来提供测距/SL定位的QoS要求。
步骤5、终端1可以使用在步骤3中建立的群播和/或单播链路来获得终端2至n的侧链定位能力。
可以执行步骤4和步骤5来传送没有由LMF服务的终端的信息。
注：终端2/.../终端n不被假定由服务于终端1的相同LMF来服务。
注：需要验证的是，RAN2将为步骤4和5提供支持。
步骤6、基于终端1/…/终端n的侧链定位能力，目标终端确定要执行SL-MO-LR。如果终端1是定位终端(即，当目标终端是终端2/…/终端n中的一个并且不具有NAS连接时)，则目标终端向终端1发起SL-MO-LR服务请求。
步骤7、如果终端1处于CM-空闲(IDLE)状态，则终端1发起终端触发的服务请求，以便与终端1的服务AMF建立信令连接。
步骤8、终端1在上行链路网络附属存储传输UL NAS TRANSPORT消息中向服务AMF发送补充服务SL-MO-LR请求。SL-MO-LR请求指示其他终端2至n(使用应用层标识(Application Layer ID)和/或通用公共用户标识(Generic Public Subs cription Identifier，GSPI))，指示所需的任何辅助数据，指示是否需要位置计算辅助，并且指示位置结果是否应该被传送到位置服务LCS客户端或AF。该消息应包括位置服务LCS客户端或AF的身份，并可能包括网关移动位置中心(Gateway Mobile Location Center，GMLC)的地址，通过该地址应访问位置服务LCS客户端和AF(通过网络存储功能(Network Repository Function，NRF))。此外，可以包括指示终端请求位置服务LCS客户端的哪个MO-LR服务的服务类型。对于来自LMF的位置计算辅助，包括优选类型的侧链定位/测距位置结果(例如，绝对位置、相对位置或终端对之间的距离和方向)和所需服务质量(Quality of Service，QoS)。如果终端1是定位终端，终端2/…/终端n中任一一个与终端1之间没有非接入层(Non-access stratum，NAS)连接的是目标终端，补充服务SL-MO-LR请求包括终端2/.../终端n是目标终端，而不是终端1。
注：FFS是否指示需要来自终端的辅助数据，该辅助数据将与RAN WG对齐。
注：能否获得其他终端的GPSI将进一步与SA WG3保持一致。
步骤9、服务AMF选择服务终端1的LMF(例如，支持侧链定位/测距的LMF)，并利用来自SL-MO-LR请求的信息向LMF发送Nlmf_LocationDetermine-Location服务操作。服务操作包括LCS相关标识符(Correlation ID)。
步骤10、LMF向终端1发送对终端1至n的能力的请求。
注：终端2/.../终端n不被假定由服务于终端1的相同LMF来服务。
注：LMF还服务于终端2/…时，FFS是更新/终端n与RAN对准。
步骤11、终端1向LMF返回其能力。如果LMF在步骤10请求，则终端1可以另外返回在步骤5获得的终端的能力。
步骤12、终端1可以向LMF发送对特定辅助数据的请求。
步骤13、LMF向终端1发送请求的辅助数据，终端1将从LMF接收到的辅助数据转发给终端2/.../终端n。辅助数据可以在步骤15帮助终端1至n获得侧链位置测量，和/或可以在步骤16帮助终端1计算侧链定位/测距位置结果。
注：如果终端1在步骤8的SL-MO-LR请求中包括包含终端1到n的能力的消息，则可以省略步骤10和11。如果终端1在步骤8的SL-MO-LR请求中包括包含对特定辅助数据的请求的消息，则可以省略步骤12。
注：是否需要步骤10-11将与RAN WG相一致。
步骤14、如果在步骤8的SL-MO-LR请求指示需要位置计算辅助和/或指示向位置服务LCS客户端或AF传送侧链定位/测距位置结果，则LMF向终端1发送对定位信息的请求，并且还可以向终端2/.../终端n发送请求，如果它由LMF服务。如果LMF确定应用基于终端的SL定位，则LMF在请求中包括对基于终端的SL定位的指示。如果在步骤8请求绝对位置，则LMF还可以提供候选定位终端的列表。如果在步骤14接收到调度的定位时间。LMF可以包括调度的位置时间。
注：如果在步骤13或步骤14中提供候选定位终端的列表，则它需要与RAN WG2对准。
步骤15、终端1在终端1至n之间发起侧链定位/测距过程，其中终端1至n获得侧链位置测量，并 且终端2至n将其侧链位置测值传送到终端1和/或LMF(取决于所请求的辅助)。如果在步骤14接收到调度的位置时间，则在调度的位置时刻执行侧链定位/测距。
步骤16、如果在步骤8需要目标终端的绝对位置信息，并且如果定位终端的绝对定位不可用，则目标终端向定位终端发送请求以触发第五代移动通信技术核心网(5th generationfifth generation Core)5GC-MO-LR过程，以使定位终端获取其自己的绝对位置。在步骤8接收到的QoS要求包括在请求中，该请求用于导出定位终端定位的QoS。
步骤17、如果LMF确定使用基于终端的计算，则终端1/…/终端n中的至少一个基于在步骤15获得的侧链位置测量并且可能使用在步骤13接收的辅助数据来计算侧链定位/测距位置结果。侧链定位/测距位置结果可以包括与终端1至n相关的绝对位置、相对位置或范围和方向。
步骤18、如果终端1在步骤14接收到对位置信息的请求，则终端1向LMF发送响应，并且包括在步骤15获得的侧链位置测量、如果执行了步骤17则在步骤17获得的侧链定位/测距位置结果、或者在步骤16获得的定位终端的绝对位置。
步骤19、如果在步骤8需要目标终端的绝对位置信息，并且如果在步骤18没有接收到定位终端的绝对定位，则LMF可以本地检索定位终端的位置，或者触发到GMLC的5GC-MT-LR过程，以使用定位终端的应用层ID或GPSI来获取定位终端的绝对位置。LMF在请求中包括在步骤8接收到的QoS要求，该QoS要求用于推导定位终端的QoS。如果使用了调度的定位时间，则LMF在对GMLC的请求中包括调度的定位时刻。
步骤20、LMF根据在步骤18接收的侧链位置测量和在步骤19定位的终端的绝对位置来计算终端1至n的侧链定位/测距位置结果。侧链定位/测距位置结果可以包括与终端1至n相关的绝对位置、相对位置或范围和方向，这取决于在步骤8中接收到的位置请求。
步骤21、LMF向AMF返回Nlmf_Location_DetermineLocation服务操作响应，并且包括在步骤18接收的或者在步骤20计算的侧链定位/测距位置结果。
步骤22、如果在步骤21接收到侧链定位/测距位置结果，则AMF执行条款6.2的步骤7-12，以将侧链定位或测距位置结果发送到GMLC，并且如果在步骤8请求，则发送到AF或位置服务LCS客户端。侧链定位/测距位置结果包括在步骤8接收到的各个终端1至n的身份。
注：向AF或位置服务LCS客户端发送终端1到n的位置结果和全局身份可能需要来自终端1到n和/或来自终端1至n的本地公共陆地移动网络HPLMN的隐私验证。
步骤23、LMF在下行链路网络附属存储传输DL NAS TRANSPORT消息中向终端1返回补充服务SL-MO-LR响应，并且如果执行了步骤20，则LMF包括在步骤20计算的任何侧链定位/测距位置结果。如果终端1是定位终端，并且目标终端是终端2至n中的一个并且不具有NAS连接，则终端1可以将侧链定位/测距位置结果传送到目标终端。
因此，终端可以通过发起SL-MO-LR(侧行链路终端发起位置请求)过程，确定该终端自己的位置信息或将该终端的位置信息提供给外部客户端。但是，目前LMF在SL-MO-LR过程中，如何经由AMF向目标终端和定位终端发送请求位置信息(Request Location Information)和路由标识以实现定位，仍是需要亟待解决的问题。

可选的，在一些实施例中，在上述步骤6中，基于Sidelink定位能力、NAS连接状态、PLMN和UE1/.../UEn的路由ID，目标UE确定要执行SL-MO-LR。目标UE应仅选择同一PLMN内的定位UE。如果UE1是定位UE(即当目标UE是UE2/.../UEn之一且不具有NAS连接时)，则目标UE选择具有NAS连接的UE并向UE1发起SL-MO-LR服务请求。
可选的，在一些实施例中，在上述步骤8中，UE1在UL NASTRANSPORT消息中向服务AMF发送补充服务SL-MO-LR请求。SL-MO-LR请求指示UE1至n(使用应用层ID和/或GPSI和/或SUPI)、指示所需的任何辅助数据、指示是否需要位置计算辅助、以及指示是否应当传送位置结果向LCS客户端或AF指示UE2到UEn的NAS连接状态。该消息应包括目标UE或UE1的路由ID、LCS客户端或AF的身份，并且可以包括应该通过其访问LCS客户端或AF(经由NEF)的GMLC的地址。另外，可以包括指示UE请求LCS客户端的哪种MO-LR服务的服务类型。对于来自LMF的位置计算辅助，包括首选(或优选)类型的Sidelink定位/测距位置结果(例如绝对位置、相对位置或UE对之间的距离和方向)以及所需的QoS。如果UE1是定位UE并且UE2/.../UEn之一是不具有NAS连接的目标UE，则补充服务SL-MO-LR 请求包括UE2/.../UEn之一是目标UE的指示。目标UE而不是UE1。
可选的，在一些实施例中，在上述步骤9中，服务AMF选择服务UE1的LMF(例如，支持侧链路定位/测距的LMF)，并向LMF发送带有来自SL-MO-LR请求的信息的Nlmf_Location_DetermineLocation服务操作。服务操作包括LCS相关标识符(LCS Correlation identifier)以及UE1至UEn的终端标识(如SUPI和/或GPSI和/或应用层ID)。
示例性的，AMF->LMF：Nlmf_Location_DetermineLocation(相关标识符、UE1到UEn的SUPI和/或GPSI和/或应用层ID、SL-MO-LR请求)。
示例性的，如果在步骤8中接收到相关ID(correlation ID)，则相关ID可以是路由ID，并且如果步骤8中未包含路由ID，则AMF可以为SL-MO-LR请求分配路由ID(即相关ID)。
如图4所示，步骤141：LMF向AMF1发送Namf_Communication_N1N2MessageTransfer消息，其中包括请求位置信息、UE的SUPI或GPSI、目标UE的相关ID。
步骤142：如果AMF1没有GPSI或SUPI指示的所有UE的上下文，AMF可以向UDM发送Nudm_SDM_Get请求来查询UE的信息，包括LCS移动发起、UE位置、UE可达性tsatus、UE注册状态、UE连接状态、测距/侧链路定位订阅数据等。其中，步骤142为可选的步骤。

步骤147c(包括如下步骤147c-1和步骤147c-2)：部分UE与AMF1有NAS连接，部分UE与AMF2有NAS连接，部分UE没有NAS连接。所有定位的UE都将其信息发送到目标UE，目标UE发送到其服务AMF(AMF1或AMF2)，如果目标UE没有NAS连接，则进一步发送到UE1。其中，步骤147c-1和步骤147c-2未在图4中示出。
示例性的，步骤147a：对于包括目标UE和定位UE在内的所有UE都可以与AMF1建立信令连接的情况，UE向AMF1发送包含提供位置信息、路由ID、UE标识、测距角色的UL NAS TRANSPORT消息。
步骤147b-1：对于并非所有UE都能与AMF1建立信令连接的情况，例如UEn没有NAS连接而UE2由AMF2服务。UEn通过PC5接口将提供位置信息、路由ID和UE标识发送给UE1或目标UE。

步骤147c-1：UEn(没有NAS的定位UE或有NAS但具有不同服务AMF的定位UE)->UE2(没有NAS的目标UE)、UE1(有NAS的定位UE)->UE2(目标UE)；和，UE2(没有NAS的目标UE)–>UE1(具有NAS并与网络连接的定位UE)：提供所有UE的位置信息(来自所有定位的UE)、路由ID、UE标识(GPSI和/或SUPI)，所有UE的测距角色。
步骤147c-2：UE1->LMF：提供位置信息(来自所有定位的UE)、路由ID、所有UE的UE标识(GPSI和/或SUPI)、所有UE的测距角色。
步骤148：根据收到的NAS消息中的路由ID(即Correlation ID)，不同的AMF可以向同一个LMF发送Nlmf_Location_DetermineLocation请求，包括提供位置信息、路由ID、UE标识、测距角色。
步骤149：涉及LMF的SL-MO-LR过程的步骤18-步骤23。其中，步骤18-步骤23的描述可参见图2中步骤18-步骤23的描述，此处不再赘述。
