301、LMF向第一接入网设备发送位置信息请求(position information request)，该位置信息请求用于请求配置终端发送SRS；
第一接入网设备为与该终端设备连接的接入网设备，也可以理解为服务-接入网设备(seving-NG-RAN，S-NG-RAN)。
302、第一接入网设备确定上行SRS资源。
303、第一接入网设备向终端设备发送终端设备的SRS配置。
304、第一接入网设备向LMF发送位置信息响应(position information response)，位置信息响应包括SRS的配置。
305、终端设备发送SRS。
例如，终端设备可通过广播的方式发送SRS。可以理解，与该终端设备连接的第一接入网设备，以及相邻接入网设备(neighbour-NG-RAN，N-NG-RAN)都可以接收到终端设备广播的SRS。相邻接入网设备可理解为，终端设备附近的除该第一接入网设备之外的其他的接入网设备。
306、LMF向第一接入网设备发送测量请求，请求对SRS信号进行测量，以得到能够用于对终端设备进行定位的测量结果。
可选的，LMF还可以向相邻接入网设备发送测量请求，请求对SRS信号进行测量。
307、第一接入网设备对SRS进行测量。
可选的，相邻接入网设备也可以对SRS进行测量。
308、第一接入网设备向LMF发送测量响应，该测量响应包括测量结果。
可选的，相邻接入网设备也可以向LMF发送测量响应，该测量响应包括测量结果。
309、LMF确定终端设备的定位。
这样，LMF可根据接收到的测量响应，确定终端设备的定位。
如图4所示的流程示意图，下行定位中，终端设备或LMF可根据测量多个接入网设备发送的下行定位参考信号(positioning reference signal，PRS)得到的测量结果，获得终端的位置。下行定位可包括以下步骤：
401、LMF向第一接入网设备发送传输接收点(transmission reception point，TRP)信息请求(information request)。
第一接入网设备为与该终端设备连接的接入网设备，也可以理解为服务-接入网设备(seving-NG-RAN，S-NG-RAN)。
可选的，相邻接入网设备(neighbour-NG-RAN，N-NG-RAN)也可以向第一接入网设备发送TRP信息请求。相邻接入网设备可理解为，终端设备附近的除该第一接入网设备之外的其他的接入网设备。
TRP请求可请求接入网设备的下行定位参考信号(positioning reference signal，PRS)的配置信息。
402、第一接入网设备向LMF发送TRP信息响应(information response)。
可选的，相邻接入网设备，也可以向LMF发送TRP信息响应，TRP信息响应包括PRS的配置信息，TRP的位置等信息。
403、终端设备、第一接入网设备和LMF之间传输辅助信息；
通过该步骤，可将辅助信息发送给终端设备。辅助信息包括至少一个TRP的PRS配置信息。可选的，相邻接入网设备，也可以参与辅助信息的传输。
404、LMF向终端设备发送请求位置信息(request location information)，请求终端设备测量PRS。
具体地，LMF请求终端设备对第一接入网设备和/或相邻接入网设备发送的PRS进行测量。
405、终端设备对PRS进行测量。
406、终端设备向LMF发送提供位置信息(provide location information)，该提供位置信息包括终端设备对PRS的测量结果。
下行定位可分为基于LMF的定位和基于终端设备的定位。在基于LMF的定位的方案中，由LMF确定终端设备的位置。终端设备通过提供位置信息将测量结果发送给LMF，由LMF确定终端设备的位置。
在基于终端设备的定位方案中，由终端设备根据测量结果确定自身的位置，并将通过提供位置信息将自身的位置发送给LMF。
下面结合本申请实施例的定位方法，详细阐述本申请实施例的技术方案。
如图5A所示的流程示意图，本申请实施例的定位方法可包括以下步骤：
501、AMF向LMF发送请求消息，用于请求终端设备的位置，或者请求对终端设备定位；
该请求消息可以是LMF定位确定位置请求(Nlmf location determine location request)。该请求消息包括定位的完好性(integrity)的信息。
完好性又可以称为完整性，或者可以理解为置信度。完好性能够表征定位的可信程度。完好性的信息可以包括用于指示对定位的完好性的需求的信息。
可选的，该请求消息包括定位的服务质量(quality of service，QoS)，QoS包括定位的完好性的信息。QoS还可以包含定位的需求如精度范围等。本申请的技术方案，在QoS中增加完好性的信息，完好性的信息中的指示对定位的完好性的需求的信息，可作为定位的质量需求，这样LMF可根据QoS选择合适的定位方案，对终端设备进行定位。
完好性的信息包括以下至少一种：
告警界限(alert limit，AL)，告警界限表征可接受的定位误差的界限值；
置信度风险(integrity risk，IR)，置信度风险表征定位误差大于告警界限的概率，或置信度风险表征定位误差小于告警界限的概率，或置信度风险表征定位误差大于或等于告警界限的概率，或置信度风险表征定位误差小于或等于告警界限的概率。
告警时间(time to alert，TTA)，告警时间表征定位不可用后到发出告警的允许时间。定位不可用指对终端的定位不符合完好性的需求。
这样，通过告警界限、置信度风险以及告警时间中的一种或多种指示定位的完好性的需求，以使得LMF获取终端设备的位置的过程中，能够根据请求消息中的完好性的信息，确定定位的需求，以对定位的可靠性进行评估。
可选的，完好性的信息包括完好性的关键性能指标(key performance indicator，KPI)。完好性的关键性能指标用于指示对定位的完好性的指标需求。上述的告警界线、置信度风险和告警时间可理解为完好性的KPI。这样，完好性的关键性能指标能够更准确地表征定位的完好性的需求，以使得LMF获取定位的过程中，能够根据请求消息中的完好性的信息，确定定位的需求，以对定位的可靠性进行评估。
502、LMF对终端设备进行定位。
应理解，定位的方案可分为基于LMF的定位和基于终端设备的定位。基于LMF的定位的场景下，由LMF确定终端设备的位置。基于终端设备的定位，由终端设备自身确定自 己的位置之后，再将自己的位置发送给LMF。
本申请的技术方案中，AMF向LMF发送的请求消息中包括完好性的信息，该完好性的信息包括用于指示对定位的完好性的需求的信息，这样LMF获取定位的过程中，能够根据请求消息中的完好性的信息，确定定位的需求，对定位的可靠性进行评估，从而有助于确定定位的可靠性。
完好性的信息还可以包括保护等级(protection level，PL)，PL表征定位误差的统计值，用于检验定位误差是/否在告警区间内。例如，告警区间可以是定位误差大于告警界限的区间，或者告警区间可以是定位误差大于或等于告警界限的区间。本申请不限定告警区间与告警界限的关系。PL可以不是完好性的关键性能指标。请求消息中，可不包括PL。
具体来说，水平方向的PL是水平方向位置错误的统计值范围，垂直方向的PL是垂直方向位置错误的统计值范围。
在基于LMF的定位的场景下，LMF定位的过程中，可计算PL。例如，告警区间是定位误差大于告警界限的区间。LMF将PL与请求消息中所包含的AL进行比较，若PL>AL，则标识定位不可用，向AMF发送告警消息。
如图5B所示的流程示意图，定位方法还包括：
503、LMF确定是/否需要发送告警消息；
具体地，LMF可根据AL得到告警区间，并判断PL是否在告警区间内。若PL在告警区间内，则LMF可确定需要发送告警消息；若PL不在告警区间内，则LMF可确定不需要发送告警消息。
例如，告警区间是PL>AL的区间。LMF将PL与请求消息中所包含的AL进行比较，若PL>AL，则LMF可确定需要发送告警消息。若PL≤AL，则LMF可确定不需要发送告警消息。
504、若是，LMF向AMF发送告警消息。
可以理解，PL在告警区间内，则可以认为定位是不可靠的。这样，在PL在告警区间内时，LMF向AMF发送告警消息，可以及时地通知AMF定位不可靠。
进一步地，AMF可以通过网关移动位置中心(gateway mobile location center，GMLC)将告警消息发送客户端(Client)。或者说，AMF可将告警消息发送给GMLC，GMLC可以进一步发给Client。
如图5C所示的流程示意图，定位方法还包括：
505、AMF向GMLC发送告警消息；
506、GMLC向Client发送告警消息。
这样，客户端的用户能够根据告警消息及时获知定位不可靠，也便于用户及时采取应对措施。
在另一些可选的实施例中，AMF可向终端设备发送告警消息。
如图5D所以的流程示意图，定位方法还包括：
507、AMF向终端设备发送告警消息。
这样，终端设备的用户能够根据告警消息及时获知定位不可靠，也便于终端设备或用 户及时做出相关的响应。
如图5E所示的流程示意图，在基于终端设备定位的场景下，步骤502可包括以下步骤：
5021、LMF向终端设备发送完好性的信息；
LMF向终端设备发送完好性的信息可包括完好性的KPI。
例如，定位过程中，LMF可向终端设备发送请求位置信息。可选的，LMF还可向终端设备发送提供辅助数据消息。
具体地，完好性的信息可携带在请求位置信息(request location information)和/或提供辅助数据(provide assistance data)消息中。
在一种可能的实现方式中，请求位置信息包括完好性的信息，而提供辅助数据消息不包括完好性的信息。
在另一种可能的实现方式中，提供辅助数据消息包括完好性的信息，而请求位置信息不包括完好性的信息。
在又一种可能的实现方式中，请求位置信息包括一部分的完好性的信息，提供辅助数据消息包括另一部分完好性的信息。
可选的，提供辅助数据消息中还可以包括用于辅助确定终端设备的位置的辅助信息，例如PRS的配置信息。
5022、终端设备确定自身的位置；
具体地，终端设备可根据对PRS进行测量，并根据测量结果得到自身的位置，还可以得到PL。
例如，终端设备可根据测得的用于定位的测量量确定自身的位置，并确定PL。PL可以是根据终端设备测得的测量量，终端设备的位置，或者其他LMF提供的辅助信息中的一种或多种得到的。
可选的，定位方法还可以包括：
5023、终端设备根据PL检验定位误差是/否在告警区间；
5024、若是，终端设备向LMF发送告警消息。
例如，告警区间可以是定位误差大于告警界限的区间，终端设备可将PL与完好性的信息中的AL进行比较，若PL>AL，则标识定位不可用，向LMF发送告警消息。LMF可进一步的向AMF和/或客户端发送该告警消息。或者，终端设备可以向LMF发送告警消息和自己的位置。
应理解，判断是/否告警的方案除了比较AL与PL，还可以是其他方案。例如，可根据测量量的异常情况确定是否告警。具体来说，若异常测量量的数量大于设定的数量，则可以发送告警消息。
终端设备可向LMF发送提供位置信息(provide location information)，该提供位置信息包括终端设备的位置以及告警消息。
可选的，告警消息可包括位置不可信的等级和PL中的至少一种。这样能够使得LMF更准确地获得定位的可信程度。
5025、若否，终端设备向LMF发送自身的位置信息。
终端设备可向LMF发送提供位置信息，该提供位置信息包括终端设备的位置。这样，在基于终端设备定位的场景下，终端设备也能从LMF获得完好性的信息，并根据完好性的信息确定是/否需要发送告警消息，以在定位的位置不可信时，及时告警，提升基于终端设备定位的场景下，定位的可靠性。
可选的，该告警消息还可以包括位置不可信的等级或PL中的至少一种。这样，LMF可根据告警消息更准确地确定定位的位置不可信的程度，可以相应的调整定位方案，从而获取更准确的定位。
可选的，如图5F所示，在步骤501之前，定位方法还可包括：
508、客户端向AMF发送定位服务请求，该定位服务请求用于请求定位；
该定位服务请求包括定位的完好性的信息；或者该定位服务请求包括定位的QoS，QoS包括定位的完好性的信息。具体地，定位服务请求可以是Client通过GMLC发送给AMF的。
这样，可由客户端在向AMF发送的定位服务请求中携带完好性的信息，再由AMF将该完好性的信息发送给LMF，以便于LMF或终端设备根据完好性的信息对定位的可靠性进行评估。
应理解，该图5F对应的实施例可以单独实施，也可与上述图5A-图5E对应的任意实施例结合实施。
可选的，如图5G所示的流程示意图，在步骤501之前，定位方法还可包括：
509、终端设备向AMF发送定位服务请求，该定位服务请求用于请求定位，该定位服务请求包括定位的完好性的信息；或者该定位服务求包括定位的QoS，QoS包括定位的完好性的信息。
这样，可由终端设备在向AMF发送的定位服务请求中携带完好性的信息，再由AMF将该完好性的信息发送给LMF，以便于LMF或终端设备根据完好性的信息对定位的可靠性进行评估。
应理解，该图5G对应的实施例可以单独实施，也可与上述图5A-图5E对应的任意实施例结合实施。
在一些实施例中，定位测量的设备在向LMF提供测量结果时，携带用于辅助确定定位是/否可靠的相关信息。例如，定位测量的设备在向LMF提供测量结果时，携带用于确定PL的测量量。这样确定终端设备的位置的设备，能够得到用于辅助确定PL的测量量，从而确定PL，确定定位是否可靠，从而可以更好地评价定位是否可信，提升定位的可靠性。LMF还可以根据PL确定是/否需要发送告警消息，以在定位不可信时，及时通过告警消息进行提醒。定位测量的设备为测量位置信息的设备。定位测量设备可以是终端设备，也可以是接入网设备。
根据上述描述可知，定位技术分为上行定位和下行定位。在上行定位的场景下，定位测量的设备是接入网设备，在下行定位的场景下，定位测量的设备是终端设备。
下面结合定位方法分别阐述，上行定位的场景下和下行定位的场景下，测量量的传输方案。
如图6A所示的流程示意图，在上行定位的场景下，定位方法包括以下步骤：

关于步骤601的相关描述以及补充说明，请参考上述实施例中步骤501的相关描述。
602、LMF向接入网设备发送第一请求，该第一请求用于请求测量量，第一请求所请求测量的测量量包括用于辅助确定保护等级的测量量；
应理解，第一请求用于请求获取一个或多个测量量，该一个或多个测量量包括用于获取保护等级的测量量，还可以包括其他与完好性相关的测量量。其他与完好性相关的测量量是指除用于获取保护等级的测量量之外的与完好性相关的测量量。
可选的，第一请求所请求的测量量还包括用于获取终端设备的位置的测量量。
603、接入网设备向LMF发送第一请求所请求测量的测量量；
接入网设备根据第一请求，向LMF发送第一请求所请求测量的测量量。可以理解，该接入网设备向LMF发送的测量量为测量之后的测量结果。
该第一请求可以通过测量请求(measurement request)发送；接入网设备通过测量响应/或测量报告(measurement response/measurementreport)向LMF发送第一请求所请求的测量量。
604、LMF获取终端设备的位置以及保护等级。
在基于LMF定位的场景下，LMF可根据接入网设备反馈的测量量，确定终端设备的位置以及PL。
在基于终端设备定位的场景下，LMF可从终端设备接收终端设备的位置和保护等级。
605、LMF参考PL和AL，确定是/否需要发送告警消息。
具体地，LMF可根据AL得到告警区间，并判断PL是否在告警区间内。若PL在告警区间内，则LMF可确定需要发送告警消息；若PL不在告警区间内，则LMF可确定不需要发送告警消息。
例如，告警区间是PL>AL的区间。LMF将PL与请求消息中所包含的AL进行比较，若PL>AL，则LMF可确定需要发送告警消息。若PL≤AL，则LMF可确定不需要发送告警消息。
606、若是，LMF向AMF发送告警消息。
可选的，LMF还可以向AMF发送终端设备的位置。
607、若否，LMF向AMF发送终端设备的位置。
这样，在上行定位的场景下，由接入网设备向LMF发送用于获取PL的测量量，使得LMF能够根据接入网设备提供的测量量获得PL，并能够在PL在告警区间内时，确定定位不可靠并及时向AMF发送告警消息。

下面分别介绍终端设备接收第一辅助信息的方案，和LMF接收第二辅助信息的方案。
例如，请参考图4，在下行定位的场景下，LMF可以通过步骤403中涉及的提供辅助数据(provide assistance data)消息或步骤404对应的请求位置信息(request location information)向终端设备发送该第一辅助信息。或者说，终端设备通过请求位置信息接收来自LMF的第一辅助信息。
具体地，如图8A所示的流程示意图，在一些可能的实现方式中，定位方法可包括以下步骤：

应理解，步骤802在步骤801之后执行，不限于步骤802紧接着步骤801之后执行。在步骤801之后，步骤802之前，定位方法还可以包括其他步骤。例如，在步骤801之后，步骤802之前，LMF可向接入网设备发送传输接收点(Transmission Reception Point，TRP)信息请求(information request)，接入网设备可向LMF发送TRP信息响应(information response)。
803、LMF向终端设备发送请求位置信息(request location information)；
804、终端设备向LMF发送提供位置信息。
其中，提供辅助数据消息和请求位置信息中的至少一个，包括第一辅助信息。第一辅助信息用于辅助确定终端设备的位置和/或确定保护等级。例如，提供辅助数据消息和请求位置信息中的一个或多个，包括无线接入技术(redio access technology，RAT)实时完好性信元(real-time integrity)信元，该RAT real-time integrity信元包括辅助信息。
应理解，本申请中，可以仅在提供辅助数据消息中包括第一辅助信息，而在请求位置信息中不包括第一辅助信息；也可以仅在请求位置信息中包括第一辅助信息，而在提供辅助数据消息中不包括第一辅助信息；还可以在请求位置信息和提供辅助数据消息中均包括第一辅助信息。在请求位置信息和提供辅助数据消息中均包括第一辅助信息的情况下，请求位置信息和提供辅助数据消息中可包括相同的第一辅助信息，或者请求位置信息包括第一辅助信息的一部分，而提供辅助数据消息中包括第一辅助信息的另一部分。
这样，在基于终端设备定位的场景下，终端设备能够获得足够的辅助信息，以辅助终端进设备确定自身的位置，以及辅助终端设备确定定位的PL，能够使得终端设备及时判断自身的位置是/否可信，并在位置不可信时及时发送告警消息，从而能够更好地保证定位的可靠性。
可选的，在步骤802之前，LMF可从接入网设备获得第一辅助信息。具体地，如图8B所示的流程示意图，在步骤802之前，定位方法还可包括：
805、LMF向接入网设备发送辅助信息请求；
辅助信息请求用于请求第一辅助信息。
806、接入网设备向LMF发送第一辅助信息。
例如，步骤805中，LMF可向接入网设备发送TRP信息请求(information request)，该TRP信息请求包括辅助信息请求，或者该TRP请求用于请求第一辅助信息。步骤806中，接入网设备可向LMF发送TRP信息响应(information response)；该TPR信息响应中包括第一辅助信息。这样，LMF通过TRP信息请求和TRP信息响应从接入网设备获得第一辅助信息，较好地与已有的定位流程适配。
在另一些实施例中，在基于LMF定位的场景下，LMF可接收来自终端设备或接入网设备的第二辅助信息。LMF能够从第二辅助信息中获取用于辅助确定终端设备的位置和/或确定保护等级的信息，从而能够更好地确定终端设备的位置和/或保护等级。

可选的，在接入网设备向LMF发送的位置信息响应之前，LMF向接入网设备发送位置信息请求，位置信息请求可请求第二辅助信息。这样，接入网设备可根据位置信息请求，在向LMF发送的位置信息响应中携带第二辅助信息。或者，位置信息请求也可以不请求第二辅助信息。接入网设备也可以在向LMF发送的位置信息响应中携带第二辅助信息。
可选的，位置信息响应中的第二辅助信息可包括但不限于包括SRS错误模型。
