可选地，在5G系统中，一个RAN设备(如gNB)按协议栈还可进一步地划分为集中单元(central unit,CU)和分布式单元(distributed unit,DU)，其中CU和DU可以分别部署在不同的物理设备上。CU负责RRC层、SDAP层以及PDCP层的操作，DU负责RLC层、MAC层以及PHY层的操作。图2(a)示出了一种划分为CU和DU的gNB的架构。其中，一个gNB可包含一个CU以及一个或多个DU，该一个或多个DU由该一个CU所控制。一个DU与CU通过控制面接口(如F1-C)连接，用于传输控制面数据；一个DU与CU通过用户面接口(如F1-U)连接，用于传输用户面数据。进一步地，CU还可划分为控制面的集中单元(即集中单元控制面CU-CP网元)和用户面的集中单元(即集中单元用户面CU-UP网元)，其中CU-CP和CU-UP也可以分别部署在不同的物理设备上，CU-CP负责RRC层和PDCP层控制面的处理，CU-UP负责SDAP层和PDCP层用户面的处理。图2(b)示出了一种划分为CU-CP、CU-UP和DU的gNB的架构。其中，一个gNB可包含一个CU-CP、一个或多个CU-UP以及一个或多个DU。一个CP-UP仅与一个CU-CP通过控制面接口(如E1)连接，用于传输控制面数据；一个DU仅与一个CU-CP通过控制面接口(如F1-C)连接，用于传输控制面数据；在CU-CP的控制下，一个DU可以与一个或多个CU-UP连接，一个CU-UP也可以与一个或多个DU连接，CU-UP与DU之间通过用户面接口(如F1-U)连接，用于传输用户面数据。值得说明的是，为了保持网络的弹性，一个DU或一个CU-UP也可以和多个CU-CP连接。此时，多个CU-CP彼此作为备份；在实际应用中，同一时刻只有一个CU-CP在运行。应理解，对于划分为CU和DU的RAN设备架构而言，上述RAN设备划分为CU和DU所根据的协议栈划分方式仅是示例性的，RAN设备也可以根据其他划分方式划分CU和DU，例如可以由CU负责RRC层、SDAP层、PDCP层以及RLC层的操作，由DU负责MAC层以及PHY层的操作；或者由CU负责RRC层以及SDAP层的操作，由DU负责PDCP层、RLC层、MAC层以及PHY层的操作等；类似地，CU中的CU-CP和CU-UP之间的协议栈划分方式也是可变的；申请对此不作具体限定。
示例性的，本申请实施例提出的通信系统可以使用5G技术。如图3所示，图3为本申请实施例提出的一种定位系统架构示意图。该定位系统包括终端设备310、RAN设备330和CN设备，其中，RAN设备330示例性地可以是gNB或ng-eNB，CN设备示例性地包含接入与移动性管理功能(access and mobility management function,AMF)单元340和定位管理功能(location management function,LMF)单元320。终端设备310与RAN设备330之间存在通信连接，具体的，终端设备310与gNB之间通过NR-Uu空口进行无线通信；终端设备310与ng-eNB之间通过LTE-Uu空口进行无线通信。应理解，图3所示的RAN设备330是示例性的，在实际网络中，RAN可以包含一个或多个gNB，也可以包含一个或多个ng-eNB，还可以包含一个或多个gNB与ng-eNB的组合，其中，RAN中不同的RAN设备之间可以通过Xn接口通信，RAN设备330(gNB或ng-eNB)与AMF单元340之间通过NG-C接口进行通信，AMF单元340相当于gNB与LMF单元320通信的路由器。LMF单元320实现终端 设备310的位置估计，AMF单元340与LMF单元320间通过NLs接口进行通信。
终端设备的定位是5G系统的重要功能之一。3GPP R16版本中定义了多种终端设备的定位技术，其中包括基于上行测量的定位技术，如基于上行信道探测参考信号(sounding reference signal,SRS)的参考信号接收功率(reference signal received power,RSRP)、上行到达时间差(uplink-time difference of arrival,UL-TDOA)、上行到达角(uplink-azimuth angle of arrival,UL-AoA)等的定位技术。在基于上行SRS-RSRP技术中，示例性地，一个或多个RAN设备或该一个或多个RAN设备的TRP分别接收终端设备发送的上行SRS，测量接收到的RSRP，并将测量结果上报给LMF，LMF根据每个小区上报的SRS-RSRP来计算终端设备的物理位置。在本文中，SRS-RSRP也称为接收到的SRS的信号强度。在UL-TDOA技术中，示例性地，一个或多个RAN设备的多个小区分别接收终端设备发送的上行SRS，测量上行链路相对到达时间(plink-relative time of arrival,UL-RTOA)，并将测量结果上报给LMF，LMF根据每个小区上报的UL-RTOA来计算终端设备的物理位置。在本文中，UL-RTOA也称为上行SRS的到达时间信息。在UL-AoA技术中，示例性地，一个或多个RAN设备的多个小区分别接收终端设备发送的上行SRS，测量到达角(azimuth angle of arrival,AoA)和/或俯仰角(zenith angle of arrival,ZoA)，并将测量结果上报给LMF，LMF根据每个小区上报的AoA和/或ZoA来计算终端设备的物理位置。在本文中，UL-AoA也称为上行SRS的到达角度信息。值得说明的是，上述基于上行测量的定位技术在3GPP TS38.305技术规范中有详细的描述，本申请在此不再赘述。
在上述基于上行测量的定位方法中，一般地，LMF需要首先获取待定位的终端设备发送上行SRS的配置，并将该上行SRS配置发送给用于协助定位该终端设备的一个或多个RAN设备，由这个(些)RAN设备根据该上行SRS配置测量该终端设备发送的上行SRS以获得测量量，例如SRS-RSRP、UL-RTOA、或UL-AoA等，并将相应的测量结果上报给LMF，由LMF计算确定终端设备的物理位置，实现对终端设备的定位。通常地，LMF需要这个(些)RAN设备进行多次测量，并使用多次测量结果以对终端设备实现准确的定位。应理解，在多次测量过程中，由于终端设备的移动性和/或无线信道的时变性，同一个RAN设备在不同时间的测量结果是可以不同的。LMF可以利用这些RAN设备多次上报的测量结果有效实现终端设备的定位。为此，LMF可以指示这个(些)RAN设备周期性地进行终端设备的上行SRS测量和上报测量结果，LMF根据周期上报的测量结果计算终端设备的物理位置。在LMF完成终端设备的定位后，指示这个(些)RAN设备停止测量。发明人发现，对于周期性测量的方式，LMF指示这个(些)RAN设备进行周期性测量和上报后，有可能存在LMF因故障或其他原因而需要重启或LMF发生数据丢失等问题，导致LMF丢失了先前指示RAN设备周期测量的信息，从而失去对这个(些)RAN设备的正常管理。在这种情况下，这个(些)RAN设备会根据LMF先前指示的周期不停地进行周期性的测量和相应的测量结果的上报，导致无线资源的浪费和大量的信令开销。为此，本申请实施例提供了一种上行测量配置的技术方案。进一步地，本申请实施例的技术方案还应用于具有CU和DU的RAN设备架构，其中CU还可包括CU-CP和CU-UP分离的情况。
本文具体提供了如下几种实施例，下面结合图4至图6，以具体的方法实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。需要说明的是，图4至图6是本申请的方法实施例的示意性流程图，示出了该方法的详细的通信步骤或操作，但这些步骤或操作仅是示例，本申请 实施例还可以执行其它操作或者图4至图6中的各种操作的变形。此外，图4至图6中的各个步骤可以分别按照与图4至图6所呈现的不同的顺序来执行，并且有可能并非要执行图4至图6中的全部操作。
图4为本申请实施例提供的一种5G系统中的终端设备定位方法流程示意图。该方法400基于上行定位技术，应用于终端设备与一个或多个RAN设备以及LMF之间的交互。图4所述流程包含如下步骤：
S401、LMF从终端设备获取该终端设备的定位能力信息。
在该步骤中，LMF与终端设备交互以获取终端设备的定位能力。应理解，该终端设备是待定位的终端设备。示例性地，LMF可以使用LTE定位协议(LTE positioning protocol,LPP)能力转发(LPP capability transfer)流程获取终端设备的定位能力信息，例如终端设备支持的定位方法，或者终端设备针对某种定位方法相关的能力(如支持的带宽)等。具体地，LPP能力转发流程可参考3GPP TS37.355技术规范中描述，本申请在此不做赘述。
值得说明的是，上述步骤S401是可选的。在一种可能的实现方式中，LMF可以在该定位流程之前从其他设备上获取终端设备的定位能力信息，如从AMF上获取并保存该终端设备的定位能力信息；在另一种可能的实现方式中，LMF可以在终端设备的注册流程中获取并保存该终端设备的定位能力信息；此外，LMF还可以在其他流程中获取并保存终端设备的定位能力信息，或者LMF采用默认的定位能力信息，即LMF默认各个终端设备具有预先设置的定位能力信息。
S402、LMF向终端设备的服务RAN设备发送第一请求。相应地，该终端设备的服务RAN设备接收第一请求。
其中，第一请求用于请求获取终端设备的上行SRS配置。
在该步骤中，LMF向终端设备的服务RAN设备请求该服务RAN设备为该终端设备配置的上行SRS资源。示例性地，上行SRS配置包括SRS发送周期、SRS序列的载波间隔、循环前缀类型、频率位置以及符号数目等。应理解，上行SRS配置对应终端设备发送上行SRSS所使用的资源，也即上行SRS资源。值得说明的是，一个终端设备的服务RAN设备是当前为该终端设备提供服务的RAN设备。此外，服务RAN设备周围还存在其他的RAN设备为其他终端设备提供服务，这些其他的RAN设备可称为服务RAN设备的邻区RAN设备。

S404、服务RAN设备向LMF发送第一请求响应。相应地，LMF接收来自服务RAN设备的第一请求响应。第一请求响应是服务RAN设备对LMF发送的第一请求的响应。
其中，第一请求响应用于向LMF提供终端设备的上行信息。示例性地，该上行信息是服 务RAN设备为终端设备配置的上行SRS资源，即上行SRS配置。通过第一请求响应，LMF可以获取终端设备后续发送上行SRS所使用的上行SRS配置。
可选地，第一请求响应是NRPPa定位信息响应(NRPPa positioning information response)消息。
S405、服务RAN设备激活终端设备的上行SRS传输。
在该步骤中，服务RAN设备激活终端设备在配置的上行SRS资源上发送上行SRS。终端设备收到该激活消息后，开始根据在步骤S403a中获得的上行SRS配置发送上行SRS。
可选地，服务RAN设备通过物理下行控制信道消息或MAC控制元素激活终端设备的上行SRS传输。
值得说明的是，上述步骤S402至S405是可选的。在基于上行定位技术的终端设备定位流程中，上述步骤S402至S405不涉及邻区RAN设备与LMF之间的信息交互。此外，由于上述步骤S402至S405也可应用在其他流程，例如服务RAN设备测量与终端设备之间的信道质量的流程等。
S406、LMF向RAN设备发送第二请求。相应地，RAN设备中接收来自LMF发送的第二请求。
其中，第二请求包含测量周期和测量次数。第二请求用于LMF请求RAN设备进行上行SRS测量。可选地，第二请求包含以下一项或多项测量量：SRS-RSRP、UL-AoA或UL-RTOA。进一步地，第二请求还可以包含上行SRS配置。
在该步骤中，在一种可能的实现方式中，LMF向终端设备的服务RAN设备发送第二请求。可选地，该第二请求用于请求服务RAN设备中的多个TRP进行上行SRS测量，该多个TRP是LMF所选择的用于协助定位终端设备的TRP。在另一种可能的实现方式中，LMF分别向终端设备的服务RAN设备以及一个或多个邻区RAN设备发送第二请求；可选地，该第二请求用于请求服务RAN设备以及一个或多个邻区RAN设备进行上行SRS测量，该一个或多个邻区RAN设备是LMF所选择的用于协助定位终端设备的RAN设备；可选地，该第二请求用于请求服务RAN设备以及一个或多个邻区RAN设备中的多个TRP进行上行SRS测量，该多个TRP是LMF所选择的用于协助定位终端设备的TRP。具体地，LMF可以通过第一策略选择用于测量终端设备发送上行SRS的多个RAN设备或多个TRP。其中，第一策略可以是多样的，例如，部署在服务RAN设备周围的多个RAN设备，或服务RAN设备的多个TRP，或与终端设备之间无线链路质量较好的多个RAN设备或多个TRP等，本申请实施例对此不作限定。应理解，在该步骤前，LMF可以获知服务RAN设备以及邻区RAN设备中的各个TRP的标识(identity,ID)。第二请求可以包括LMF选择的用于协助定位终端设备的各个TRP ID。
可选地，第二请求包含测量标识，用以标识LMF针对该终端设备的该周期测量的请求。
第二请求中包含测量周期(measurement periodicity)。即，在第二请求中，LMF指示RAN设备进行上行SRS测量的周期，该周期是一个大于0的数值。示例性地，测量周期可以是120ms、240ms、480ms、640ms等。第二请求中包含测量次数(measurement number)。即，在第二请求中，LMF指示RAN设备进行上行SRS测量的次数，该测量次数是大于或等于1的整数。示例性地，测量次数可以是4次、8次、16次、32次、64次等。表1给出在第二请求中包含测量周期和测量次数的信息元素(information element,IE)。

可选地，第二请求是NRPPa测量请求(NRPPa measurement request)消息。
S407、RAN设备进行上行SRS测量。
在该步骤中，在一种可能的实现方式中，在上述步骤S406中收到第二请求的服务RAN设备根据第二请求中的上行SRS配置、测量周期和测量次数指示多个TRP对终端设备发送的SRS进行周期性的测量。在另一种可能的实现方式中，在上述步骤S406中收到第二请求的多个RAN设备中的各个RAN设备根据第二请求中的上行SRS配置、测量周期和测量次数对终端设备发送的SRS进行周期性的测量。在又一种可能的实现方式中，在上述步骤S406中收到第二请求的多个RAN设备中的各个RAN设备根据第二请求中的上行SRS配置、测量周期和测量次数指示该RAN设备的一个或多个TRP对终端设备发送的SRS进行周期性的测量。值得说明的是，邻区RAN设备可以通过其他方式从服务RAN设备获取该终端设备的上行SRS配置，例如，可通过RAN设备之间的信息交互来获取。在这种情况下，第二请求可以不包含上行SRS配置。示例性地，通过对终端设备发送的SRS进行测量可以获取以下一项或多项测量量：SRS-RSRP、UL-AoA或UL-RTOA。应理解，RAN设备根据第二请求中指示的测量周期和测量次数，依次周期性地测量上行SRS信号并获取相应的测量信息。在达到测量次数后，RAN设备将不再进行上行SRS的测量。示例性地，当测量周期为120ms、测量次数为8次时，RAN设备在收到第二请求后，每隔120ms测量一次上行SRS，并连续进行8次该测量。
S408、RAN设备向LMF发送第二请求响应。相应地，LMF接收来自RAN设备的第二请求响应。第二请求响应是服务RAN设备对LMF发送的第二请求的响应。
其中，第二请求响应用于RAN设备向LMF报告上行SRS测量结果。
在该步骤中，RAN设备将自身或该RAN设备的一个或多个TRP对上行SRS的测量结果报告给LMF。示例性地，测量结果包括以下一项或多项测量量：SRS-RSRP、UL-AoA或 UL-RTOA。应理解，RAN设备根据第二请求中指示的测量周期和测量次数，依次周期性地向LMF报告上行SRS测量结果。在达到测量次数后，RAN设备将不再向LMF报告测量结果。示例性地，当测量周期为120ms、测量次数为8次时，RAN设备在收到第二请求后，每隔120ms测量上行SRS获取测量信息后向LMF报告上行SRS测量结果，并连续进行8次该报告。
可选地，第二请求响应是NRPPa测量响应(NRPPa measurement response)消息。
在上述步骤S406中，LMF通过在第二请求中指示RAN设备的测量次数使得RAN设备可以在对终端设备发送的上行SRS测量达到测量次数后停止对上行SRS的测量以及相应的测量结果的上报。在另一种可能的实现方式中，在上述步骤S406中，LMF向RAN设备发送的第二请求包含测量周期和测量时长(measurement interval)。即，在第二请求中，LMF指示RAN设备周期地进行上行SRS测量和相应的测量结果上报的时长，该测量时长是大于0的整数。示例性地，测量时长可以是1200ms、2400ms、3600ms等。表2给出在第二请求中包含测量周期和测量时长的IE。
表2 第二请求包含的另一种IE
Figure PCTCN2021093967-appb-000002
在表2中，Measurement Interval是一个条件型的枚举类型的标识测量时长的IE，其在Report Characteristics为Periodic的条件时有效，即在C-ifReportCharacteristicsPeriodic存在时有效，其中测量时长可以如表2示例中取值为1200ms、2400ms或4800ms等。在这种情况下，在上述步骤S407中，RAN设备在达到测量时长后，将不再进行上行SRS测量。示例性地，当测量周期为120ms、测量时长为1200ms时，RAN设备在收到第二请求后，每隔120ms测量一次上行SRS，并连续进行10次该测量后停止测量。类似地，在上述步骤S408中，RAN设备在达到测量时长后将不再向LMF报告测量结果。
在又一种可能的实现方式中，在上述步骤S406中，LMF向RAN设备发送的第二请求包含测量周期和SRS-RSRP阈值(RSRP threshold)。该SRS-RSRP阈值用于指示RAN设备在检测到终端设备的上行SRS的强度低于SRS-RSRP阈值时，RAN设备停止对该终端设备的上行SRS的测量和相应的测量结果的上报。即，在第二请求中，LMF指示RAN设备周期地进行上行SRS测量和相应测量结果上报的SRS-RSRP阈值。示例性地，信号强度阈值可以是-80dbm、-90dbm、-100dbm等。表3给出在第二请求中包含测量周期和RSRP阈值的IE。
表3 第二请求包含的又一种IE
Figure PCTCN2021093967-appb-000003
在表3中，SRS-RSRP Threshold是一个条件型的枚举类型的SRS-RSRP阈值的IE，其在Report Characteristics为Periodic的条件时有效，即在C-ifReportCharacteristicsPeriodic存在时有效，其中SRS-RSRP阈值可以如表3示例中取值为-80dbm、-90dbm或-100dbm等。在这种情况下，在上述步骤S407中，RAN设备在测量到终端设备的上行SRS-RSRP强度低于该阈值时，将不再进行上行SRS信号的测量。类似地，在上述步骤S408中，RAN设备在测量到终端设备的上行SRS-RSRP强度低于该阈值时将不再向LMF报告测量结果。
可选地，服务RAN设备在周期性上行SRS测量达到第二请求中指示的测量次数后，服务RAN设备可以指示终端设备停止发送上行SRS。示例性地，服务RAN设备通过无线资源控制(radio resource control,RRC)重配置消息指示终端设备停止发送上行SRS。
值得说明的是，在RAN设备是CU-DU分离架构的情况下，示例性地，上述步骤S402、S404、S406和S408是LMF与CU之间以及CU与DU之间的信息交互，其中上述步骤S402涉及的CU是终端设备的服务DU所连接的CU；在一种可能的实现方式中，该CU执行上述步骤S403并将上行SRS配置通过服务DU在上述步骤S403a中发送给终端设备，并且该CU通过服务DU在上述步骤S405中激活终端设备发送上行SRS；在另一种可能的实现方式中，服务DU执行上述步骤S403、S403a和S405，并将上行SRS配置发送给该CU；多个RAN设备中的DU执行上述步骤S407中的上行SRS测量，通过F1-C接口将测量结果上报给各自所连接的CU，再由CU在上述步骤S408中上报给LMF。应理解，该多个RAN设备中的不同的DU可能分别连接不同的CU，也可能存在不同的DU连接同一个CU。进一步地，在CU包含CU-CP和CU-UP的情况下，上述步骤中由CU执行的步骤改为由该CU包含的CU-CP执行。
通过本实施例上述步骤，实现了RAN设备可以在给定的条件下停止上行SRS测量和相应的测量结果上报，从而避免因为LMF的原因导致RAN设备无法停止周期测量和周期上报所造成的资源浪费和信令开销。
通过前述实施例步骤S401-S408，LMF可以获取多个RAN设备和/或多个TRP对终端设备的测量信息，并根据该多个测量信息确定终端设备的位置。通常地，在RAN设备周期性向LMF报告上行SRS测量结果的方式中，在LMF确定终端设备的物理位置后，LMF需要指示上述一个或多个RAN设备终止测量。可选地，LMF向上述一个或多个RAN设备分别发送测量终止(emasurement abort)消息，用于指示各个RAN设备停止测量。各个RAN设备收到 该测量终止消息后，不再进行上行SRS测量以及报告上行SRS测量结果。在这种情况下，如果RAN设备未成功接收来自LMF的测量终止消息，则RAN设备会继续进行上行SRS的测量以及相应的测量结果上报，造成不必要的资源浪费和系统开销。
图5为本申请实施例提供的另一种5G系统中的终端设备定位方法流程示意图。该方法500基于上行定位技术，应用于协助定位终端设备的一个或多个RAN设备和LMF之间的交互。图5所述流程包含如下步骤：
S501、LMF向RAN设备发送第一指示。相应地，RAN设备接收来自LMF的第一指示。
其中，第一指示用于指示RAN设备终止测量。
在该步骤中，LMF向RAN设备发送第一指示，以指示该RAN设备终止对终端设备的上行SRS测量以及相应的SRS测量结果上报。
应理解，该RAN设备是用于协助定位终端设备的多个RAN设备中的一个RAN设备。示例性地，该RAN设备是在前述实施例步骤S406中收到来自LMF的第二请求的RAN设备。
在一种可能的实现方式中，第一指示包含测量ID，用于指示RAN设备停止该测量ID所标识的测量。示例性地，该测量ID与前述实施例步骤S406中RAN设备获取的测量ID相同。
可选地，第一指示是测量终止(measurement abort)消息。
S502、RAN设备向LMF发送的第一指示响应。相应地，LMF接收来自RAN设备的第一指示响应。第一指示响应是服务RAN设备对LMF发送的第一指示的响应。
在该步骤中，RAN设备向LMF发送第一指示响应，以告知LMF该RAN设备成功接收到来自LMF的第一指示。RAN设备在发送第一指示响应后，不再进行上行SRS测量和相应的测量结果的上报，或指示该RAN设备的一个或多个TRP不再进行上行SRS测量和相应的测量结果的上报。
在一种可能的实现方式中，第一指示响应包含第一指示中的测量ID，用于确认RAN设备成功接收针对该测量ID所标识的测量的第一指示。
可选地，第一指示响应是测量终止响应(measurement abort response)消息或测量终止应答(measurement abort acknowledgement)消息。
值得说明的是，在LMF发送第一指示后，在预设的条件内，如果LMF没有收到RAN设备发送的第一指示响应，LMF可以继续发送第一指示，直到LMF收到RAN设备发送的第一指示响应。可选地，该预设的条件是预设的时间段，即LMF在预设的时间段内没有收到RAN设备发送的第一指示响应，则继续向该RAN设备发送第一指示。
值得说明的是，在RAN设备是CU-DU分离架构的情况下，LMF向CU发送第一指示，并由CU向DU转发该第一指示；DU向CU发送第一指示响应，并由CU向LMF转发该第一指示响应。进一步地，在CU包含CU-CP和CU-UP的情况下，上述步骤中由CU执行的步骤改为由该CU包含的CU-CP执行。
通过本实施例上述步骤，实现了RAN设备与LMF的测量终止指示信息的双向交互，保证了LMF确认RAN设备正确接收测量终止指示，减少了RAN设备因为没有正确接收测量终止指示而继续周期测量和周期上报所造成的资源浪费和信令开销。
在上述实施例中，由LMF决策RAN设备何时停止上行SRS测量以及相应的测量结果上报。例如，LMF指示RAN设备进行上行SRS测量的次数、或进行上行SRS测量的时长、或 终止上行SRS测量等。在另一种可能的实现方式中，RAN设备决策何时停止上行SRS测量以及相应的测量结果上报。在这种实现方式中，RAN设备可以根据自身的资源状态决策何时不再进行上行SRS测量以及相应的测量结果上报。

S601、RAN设备确定停止上行SRS测量。
在该步骤中，RAN设备决策不再进行上行SRS测量。具体地，RAN设备根据第二策略来决定不再进行上行SRS测量。其中，第二策略可以是多样的，例如，RAN设备判断接收到的终端设备的SRS信号强度低于一个预设的阈值，或者RAN设备判断测量上行SRS的次数或时长超过一个预设的阈值，或者RAN设备资源过载不再有空闲资源用于协助定位终端设备等，本申请实施例对此不作限定。应理解，第二策略可以是RAN设备自身生成的，也可以是RAN设备从其他网络设备获取的。
S602、RAN设备向LMF发送第二指示。相应地，LMF接收来自RAN设备的第二指示。
其中，第二指示用于指示RAN设备停止上行SRS测量。
在该步骤中，RAN设备停止对上行SRS的测量，并通知LMF其不再进行上行SRS的测量以及相应的测量结果的上报。
在一种可能的实现方式中，第二指示包含测量ID，该测量ID与前述实施例步骤S406中RAN设备获取的测量ID相同，表明RAN设备停止该测量ID所指示的上行SRS测量。
可选地，第二指示是测量终止通知(measurement abort notification)消息或测量终止指示(measurement abort indication)消息。
值得说明的是，在RAN设备是CU-DU分离架构的情况下，在一种可能的实现方式中，CU在上述步骤S601中确定停止上行SRS测量并通过F1-C接口指示DU停止对终端设备的上行SRS的测量；上述步骤S602是LMF与CU之间的信息交互。在另一种可能的实现方式中，DU在上述步骤S601中确定停止上行SRS测量并通过CU向LMF发送第二指示。进一步地，在CU包含CU-CP和CU-UP的情况下，上述步骤中由CU执行的步骤改为由该CU包含的CU-CP执行。
通过本实施例上述步骤，实现了RAN设备根据自身状态主动停止上行SRS测量和相应的测量结果上报，实现RAN设备资源的有效利用。
值得说明的是，在本申请实施例中，用于位置管理的LMF还可以是其他设备，该其他设备可以是网络中用于管理终端设备位置信息的控制器或管理器，也可称为定位设备，其可以位于RAN也可以位于CN，本申请对该定位设备的名称和位置不作具体限定。
