Description

一种时间误差信息的更新方法以及相关装置
本申请要求于2021年08月06日提交中国国家知识产权局、申请号为202110904517.3、发明名称为“一种时间误差信息的更新方法以及相关装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种时间误差信息的更新方法以及相关装置。
背景技术
高精度的定位能力是未来蜂窝定位技术的发展方向之一。目前，有些定位技术中，需要获取信号在终端和不同接入网设备之间的传输时间，根据传输时间确定终端的位置。这些定位技术的定位精度依赖于获取的传输时间的准确度。
在高频毫米波频段，由于传输信道的空间损耗较为严重，终端设备(或者称为用户设备(user equipment，UE))和接入网设备通常会采用多个朝向不同的天线面板收发信号，通过波束成形增强信号强度，达到抗信道衰落的目的。天线面板连接的射频链路在收发信号时存在一定的处理时延，可以通过对该处理时延进行校准，从而使得接入网设备和终端设备保持同步。但是该处理时延与多种因素(例如：硬件参数，质量，温度，或者噪声等)相关，从而导致该处理时延不能被准确预估，也就无法被精确校准，校准之后会存在残留的时间误差。由于不同的天线面板连接至不同的射频链路，并且是相对独立安装和校准的，因此，不同的天线面板(该天线面板也可以替换为射频链路、射频通道或者天线端口)往往会存在不同的时间误差。对于同一个天线面板，上述时间误差可能随着时间的推移而发生变化。
终端设备的定位过程是通过终端设备与多个接入网设备之间收发参考信号实现，而终端设备可以通过一个或多个天线面板向多个接入网设备发送参考信号。因此，终端设备会向网络侧上报参考信号与时间误差之间的关联关系。
由于终端设备的位置或者朝向可能发生变化，因此在终端设备的定位过程中，终端设备可能通过不同的天线面板向同一个接入网设备发送参考信号。即参考信号与天线面板之间的关联关系发生变化，进一步的，该参考信号与时间误差的关联关系发生变化。而网络侧(接入网设备和定位服务器)无法感知该变化，依然使用该参考信号所关联的错误的时间误差对终端设备进行定位，进而导致定位精度降低。
发明内容
第一方面，本申请实施例提供了一种时间误差信息的更新方法，包括：终端设备向网络设备发送第一关联关系，和/或第一指示信息，所述第一关联关系包括时间误差信息与定位参考信号的关联关系，所述时间误差信息用于指示所述终端设备发送所述定位参考信号的时间误差，所述第一指示信息指示所述第一关联关系是否会动态变化和/或是否支持更新上报。
一种可能的实现方式中，终端设备可以向网络设备仅发送第一指示信息，当终端设备 向网络设备仅发送第一指示信息时，第一指示信息还可以指示第一关联关系为动态“Dynamic”，静态“Static”，或者未知“unknown”，上述第一指示信息均可指示当前无法获取第一关联关系，终端设备需要向网络设备发送定位参考信号后，确定定位参考信号对应的时间误差信息，进而确定第一关联关系，即该定位参考信号与时间误差信息之间的关联关系。终端设备向网络设备发送该第一关联关系。可选的，终端设备向网络设备发送该第一关联关系时，终端设备同时向网络设备发送更新的第一指示信息，该更新的第一指示信息指示第一关联关系是否会动态变化和/或是否支持更新上报。
在另一种可能的实现方式中，终端设备向网络设备同时发送第一关联关系和第一指示信息。这里的“同时”可以理解为终端设备在同一条信令中向网络设备发送第一关联关系和第一指示信息，也可以理解为终端设备在时间上相邻的两条或多条信令中分别向网络设备发送第一关联关系和指示信息，此处不做限制。
可以理解的是，本申请实施例涉及的定位参考信号还可以是定位参考信号(positioning reference signal，PRS)、信道状态信息参考信号(channel state information-reference signal，CSI-RS)、或者跟踪参考信号(tracking reference signal，TRS)等，此处不作限制。示例性的，对于上行定位测量，定位参考信号可以是SRS；对于下行定位测量，定位参考信号可以是PRS。
不同的天线面板(或者说不同的射频链路/射频通道)会存在不同的时间误差，即采用不同的天线面板(或者说不同的射频链路/射频通道)收发信号时，测量到的不同到达时间(time of arrival，TOA)值存在不同的时间误差。
可以理解的是，由于处理时延与多种因素(例如，硬件参数，质量，温度，噪声等)相关，因此，时间误差也与这多种因素相关，同一个天线面板(或者说同一个射频链路/射频通道)在不同时刻收发信号的时间误差并不是完全相同的，但是存在相关性，也就是说，同一个天线面板(或者说同一个射频链路/射频通道)在不同时刻收发信号的时间误差可以认为是相对稳定的(即变化不大的)。

具体的，时间误差信息用于指示终端设备发送定位参考信号的射频链路对应的时间误差。或者，时间误差信息用于指示终端设备发送定位参考信号的天线面板对应的时间误差。或者，时间误差信息用于指示终端设备发送定位参考信号的射频通道对应的时间误差。
本申请实施例中，网络设备可以及时获知终端设备的定位参考信号与时间误差的关联关系，并且，网络设备还可以获知该定位参考信号与时间误差之间的关联关系是否会动态变化和/或是否支持更新上报。使得网络设备可以使用精度更高的与定位参考信号关联的时间误差进行定位测量，提升了定位精度。

可选的，第一配置信息还可以指示终端设备周期性上报第一关联关系。例如每隔100秒上报一次第一关联关系。可选的，此时当第一关联关系为静态则不上报，或者，无论第一关联关系是否为静态或者动态(即第一关联关系是否更新支持上报)终端设备都会根据第一配置信息的指示周期性上报该第一关联关系。
示例性的，该第一配置信息可以是接入网设备向终端设备配置定位参考信号的信息时一同配置的，例如：接入网设备向终端设备发送RRC信令，该RRC信令包括SRS重配置消息，该RRC信令用于向配置终端设备该定位参考信号。该RRC信令还包括第一配置信息。
在又一种示例中，接入网设备可以单独向终端设备发送该第一配置信息。例如通过RRC信令向终端设备发送该第一配置信息。
结合第二方面，在第二方面的一种可能实现方案中，第一关联关系可以是定位参考信号与时间误差信息的关联关系。第一关联关系还可以是定位参考信号的端口(例如是SRS port)与时间误差信息的关联关系。第一关联关系还可以是定位参考信号的资源(例如承载SRS的资源(resource))与时间误差信息的关联关系。第一关联关系还可以是定位参考信号的资源集(例如：承载SRS的资源集(resource sets))与时间误差信息的关联关系。需要说明的是，第一关联关系还可以是承载定位参考信号的其它粒度的资源与时间误差信息的关联关系，第一关联关系还可以是发送定位参考信号的天线面板或者射频链路与时间误差信息的关联关系，此处不作限制。
例如：第一关联关系为某一个或多个频点的定位参考信号与时间误差信息的关联关系。
第三方面，本申请实施例提出一种时间误差信息的更新方法，包括：定位服务器接收来自终端设备的第一关联关系，和/或第一指示信息，所述第一关联关系包括时间误差信息与定位参考信号的关联关系，所述时间误差信息用于指示所述终端设备发送所述定位参考信号的时间误差，所述第一指示信息指示所述第一关联关系是否会动态变化和/或是否支持更新上报。
一种可能的实现方式中，定位服务器接收来自终端设备的第一指示信息，当终端设备向定位服务器仅发送第一指示信息时，第一指示信息还可以指示第一关联关系为动态 “Dynamic”，静态“Static”，或者未知“unknown”，上述第一指示信息均可指示当前无法获取第一关联关系，终端设备需要向定位服务器发送定位参考信号后，确定定位参考信号对应的时间误差信息，进而确定第一关联关系，即该定位参考信号与时间误差信息之间的关联关系。终端设备向定位服务器发送该第一关联关系。可选的，终端设备向定位服务器发送该第一关联关系时，终端设备同时向定位服务器发送更新的第一指示信息，该更新的第一指示信息指示第一关联关系是否会动态变化和/或是否支持更新上报。
在另一种可能的实现方式中，终端设备向定位服务器同时发送第一关联关系和第一指示信息。这里的“同时”可以理解为终端设备在同一条信令中向定位服务器发送第一关联关系和第一指示信息，也可以理解为终端设备在时间上相邻的两条或多条信令中分别向定位服务器发送第一关联关系和指示信息，此处不做限制。
可以理解的是，本申请实施例涉及的定位参考信号还可以是PRS、信道状态信息参考信号、或者跟踪参考信号等，此处不作限制。示例性的，对于上行定位测量，定位参考信号可以是SRS；对于下行定位测量，定位参考信号可以是PRS。
不同的天线面板(或者说不同的射频链路/射频通道)会存在不同的时间误差，即采用不同的天线面板(或者说不同的射频链路/射频通道)收发信号时，测量到的不同到达时间值存在不同的时间误差。
可以理解的是，由于处理时延与多种因素(例如，硬件参数，质量，温度，噪声等)相关，因此，时间误差也与这多种因素相关，同一个天线面板(或者说同一个射频链路/射频通道)在不同时刻收发信号的时间误差并不是完全相同的，但是存在相关性，也就是说，同一个天线面板(或者说同一个射频链路/射频通道)在不同时刻收发信号的时间误差可以认为是相对稳定的(即变化不大的)。
本申请实施例中，使用时间误差信息指示上述时间误差。时间误差信息用于指示终端设备发送定位参考信号的时间误差。
具体的，时间误差信息用于指示终端设备发送定位参考信号的射频链路对应的时间误差。或者，时间误差信息用于指示终端设备发送定位参考信号的天线面板对应的时间误差。或者，时间误差信息用于指示终端设备发送定位参考信号的射频通道对应的时间误差。
本申请实施例中，定位服务器可以及时获知终端设备的定位参考信号与时间误差的关联关系，并且，定位服务器还可以获知该定位参考信号与时间误差之间的关联关系是否会动态变化和/或是否支持更新上报。使得定位服务器可以使用精度更高的与定位参考信号关联的时间误差进行定位测量，提升了定位精度。

具体的，第一指示信息第一关联关系是否会动态变化，例如：第一指示信息指示第一关联关系为动态，则该第一关联关系会动态发生变化；第一指示信息指示第一关联关系为 静态，则该第一关联关系不会发生变化。第一关联关系为动态，也可以理解为第一关联关系会更新，终端设备会向网络设备上报更新后的第一关联关系或者发生变化后的第一关联关系。
第一指示信息指示第一关联关系是否支持更新上报，例如：第一指示信息指示第一关联关系支持更新上报，则终端设备中第一关联关系发生变化或者更新后，终端设备向网络设备上报该发生变化或者更新后的第一关联关系。第一指示信息指示第一关联关系不支持更新上报，则终端设备中该第一关联关系不会发生变化或者更新，或者，终端设备中该第一关联关系即使发生变化或者更新，终端设备也不会向网络设备上报该发生变化或者更新的第一关联关系。
示例性的，第一指示信息指示第一关联关系为静态，则第一指示信息可以是“static”；第一指示信息指示第一关联关系为动态，则第一指示信息可以是“dynamic”。
在又一种示例中，第一指示信息指示第一关联关系为静态，则第一指示信息可以是“1”；第一指示信息指示第一关联关系为动态，则第一指示信息可以是“0”。

可以理解的是，时间误差的时间窗除了包括未来的时间窗(即该时间窗指示未来一段时间，该时间窗内定位参考信号与时间误差信息具有关联关系)，时间误差的时间窗还可以包括过去的时间窗。过去的时间窗指的是在过去的一段时间内，该时间窗内的定位参考信号与时间误差信息具有关联关系。
结合第三方面，在第三方面的一种可能实现方案中，所述定位服务器向所述终端设备发送定位能力请求消息；所述定位服务器接收来自所述终端设备的定位能力信息，所述定位能力信息包括以下一项或多项：所述终端设备支持所述时间误差信息检测的频点信息，所述终端设备在各个频点支持的所述时间误差信息的数量，所述终端设备支持的最大的所述时间误差信息的数量，所述定位参考信号与所述时间误差信息关联关系是否支持更新上报或者动态检测。

本申请实施例提供的方法可以应用于长期演进(long term evolution，LTE)系统、第五代(5th-generation，5G)系统、新无线(new radio，NR)系统，无线局域网(wireless local area networks，WLAN)系统以及未来演进系统或者多种通信融合系统。其中，5G系统可以为非独立组网(non-standalone，NSA)的5G系统或独立组网(standalone，SA)的5G系统。为了方便描述，本申请实施例中以提供的方法应用于5G系统或NR系统中为例对本申请实施例提供的方法作示例性说明。当本申请实施例提供的方法应用于其他系统中时，将本申请实施例中的网元替换为相应系统中的具备相同或相似功能的网元理解即可。
本申请实施例中，网络侧的设备或者网元或者功能实体，统称为网络设备。在本申请实施例中，网络设备至少包括：定位服务器和接入网设备。定位服务器为终端设备提供定位服务。接入网设备为终端设备提供接入通信网络的服务。
一种可能的实现中，定位服务器位于核心网侧，定位服务器可以是定位管理功能(location management function，LMF)，也可以是其它提供定位服务的网络功能或者网元或者服务器。在另一种可能的实现中，定位服务器位于接入网侧，即定位服务器的功能集成至接入网设备中。本申请实施例中，为了便于理解，以定位服务器为LMF为例进行说明。
5G系统或NR系统的接入网可以称为下一代(next generation，NG)-无线接入网(radio access network，RAN)。NG-RAN中可以包括一个或多个接入网设备。接入网设备为网络侧的一种用于发送信号，或者，接收信号，或者，发送信号和接收信号的实体，用于为终端提供无线通信功能。NG-RAN中包含的接入网设备可以为5G站点下一代基站节点(next generation node base station，gNB)、连接到5G核心网的4G站点下一代演进型基站(next generation evolved NodeB，ng-eNB)等。NG-RAN中包含的接入网设备可以发送和/或接收定位参考信号，并获取相关的定位测量信息。
基于NG-RAN的5G核心网的定位架构可参见图1。其中，定位管理功能(为5G核心网中的提供定位功能的网元、模块或组件。接入和移动性管理功能(access and mobility management function，AMF)为5G核心网中的提供接入管理功能的网元、模块或组件。增强服务移动定位中心(evolved serving mobile location center，E-SMLC)为4G核心网中提供定位功能的网元、模块或组件。安全用户面定位(secure user plane location，SUPL)定位平台(SUPL location platform，SLP)为4G核心网中处理用户面安全定位协议的网元、模块或组件。ng-eNB是一种部署在无线接入网中满足4G标准，为终端提供无线通信功能的设备或装置。ng-eNB可以是各种形式的基站、收发参考信号的传输接收节点 (transmission and reception point，TRP)、接入点、接收点(reception point，RP)、传输点(transmission point，TP)等。gNB是一种部署在无线接入网中满足5G标准，为终端提供无线通信功能的设备或装置。gNB可以是各种形式的基站、收发参考信号的TRP、传输测量功能(transmission measurement function，TMF)、接入点、RP、TP等。终端是用户侧的一种用于接收信号，或者，发送信号，或者，接收信号和发送信号的实体。终端用于向用户提供语音服务和数据连通性服务中的一种或多种。终端可以是各种具备无线通信功能的设备终端，包括：手持终端、移动电话、手机、计算机、可穿戴设备、平板电脑、车载终端、工厂机器、工厂设备、机器类通信终端等。终端还可以称为用户设备、终端设备、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、无线通信装置、用户代理或用户装置。
需要说明的是，图1中以NG-RAN中包括一个ng-eNB和一个gNB进行示例性绘制，实际上，NG-RAN中可以包括更多个ng-eNB和/或更多个gNB。NG-RAN中参与终端设备定位的接入网设备可以全部为ng-eNB，也可以全部为gNB，还可以部分为ng-eNB，部分为gNB。
基于图1所示的定位架构对终端设备进行定位时，AMF接收网络中的其它网元发起的关于某个终端设备的定位请求消息(也可以称为定位服务请求消息)。AMF将接收到的定位请求消息发送给定位管理功能网元(例如，LMF)，定位管理功能网元负责处理接收到的定位请求消息，并发起相关的定位流程。
为了使得本申请实施例更加的清楚，首先对本申请实施例涉及到的部分概念作简单介绍。
1、到达时间。
在定位技术中，一种典型的基于信号在终端设备和不同接入网设备之间的传输时间的定位方法即基于TOA的定位方法。该方法中，终端设备测量不同接入网设备发送的定位参考信号的TOA或者不同接入网设备测量终端设备发送的定位参考信号的TOA，可以得到终端设备与接入网设备间的距离关系，再结合已知的接入网设备的位置坐标等信息估算出终端设备的位置。
参见图2，可以理解的是，若确定信号在终端设备和不同接入网设备之间的传输时间，则通过将传输时间和光速相乘可以得到终端设备和每个接入网设备之间的距离，以每个接入网设备为圆心，该接入网设备到终端设备的距离为半径作圆，可以得到多个圆，多个圆的交点即终端设备的位置。具体的，以TOA为上行到达时间差(uplink-time difference of arriaval，UL-TDOA)为例，不同的接入网设备测量终端设备发送的上行定位参考信号(即探测参考信号(sounding reference signal，SRS))的参考到达时间(relative time of arrival，RTOA)(即以某个时间点为参考的TOA)，并将测量信息上报给定位管理功能网元(例如，LMF)，定位管理功能网元将不同接入网设备的RTOA做差分运算，计算出终端设备到不同接入网设备间的距离差，然后根据接入网设备的位置信息，解算出终端设备的位置。
2、时间误差信息。
根据上文可知，不同的天线面板(或者说不同的射频链路/射频通道)会存在不同的时间误差，即采用不同的天线面板(或者说不同的射频链路/射频通道)收发信号时，测量到 的不同TOA值存在不同的时间误差。
可以理解的是，由于处理时延与多种因素(例如，硬件参数，质量，温度，噪声等)相关，因此，时间误差也与这多种因素相关，同一个天线面板(或者说同一个射频链路/射频通道)在不同时刻收发信号的时间误差并不是完全相同的，但是存在相关性，也就是说，同一个天线面板(或者说同一个射频链路/射频通道)在不同时刻收发信号的时间误差可以认为是相对稳定的(即变化不大的)。
本申请实施例中，使用时间误差信息指示上述时间误差。时间误差信息用于指示终端设备发送定位参考信号的时间误差。
具体的，时间误差信息用于指示终端设备发送定位参考信号的射频链路对应的时间误差。或者，时间误差信息用于指示终端设备发送定位参考信号的天线面板对应的时间误差。或者，时间误差信息用于指示终端设备发送定位参考信号的射频通道对应的时间误差。
时间误差信息具有多种可能的实现方式，所述时间误差信息包括以下一项或多项：所述时间误差的索引、所述时间误差的大小、所述时间误差的范围，或者所述时间误差的方差。可以理解的是，时间误差信息还存在其它的实现方式，此处不作限制。
下面进行举例说明：
2.1、时间误差的索引：终端设备与网络设备之间各自维护时间误差的索引与时间误差的映射关系，示例性的，如表1所示：
表1
Figure PCTCN2022106931-appb-000001
2.2、时间误差的大小：示例性的，该时间误差信息可以是0.2(纳秒/ns)或者0.5ns等，此处不作限制。
2.3、时间误差的范围：示例性的，该时间误差信息可以是：“[0-0.5)(纳秒)”或者“[0.5-1)(纳秒)”等，此处不作限制。
2.4、时间误差的方差：该时间误差信息还可以是对一段时间内的多个时间误差进行计算得到的方差。
本申请实施例中，对于同一个天线面板(或者说同一个射频链路)在不同时刻收发信号的多个相关的时间误差可以认为属于一个时间误差组(timing error group，TEG)，TEG也可以为其他名称，本申请不作限制。基于此，下文中的时间误差还可以替换为TEG，或者与TEG代表的含义相同的其他描述。
目前，标准协议中对时间误差组的定义如下：Tx TEG与一个或多个下行PRS(DL PRS)资源或一个或多个用于定位资源的上行SRS(UL SRS)的传输相关联，这些资源具有相同的Tx定时误差。不同的Tx TEG具有不同的Tx定时误差。“A Tx TEG is associated with the transmission of one or more DL PRS resources,or one or more UL SRS for positioning resources,which have the same Tx timing errors.Different Tx TEGs have different Tx timing errors.”。
3、天线端口(antenna port)。
天线端口表征一个逻辑的发射通道，可以映射至物理的天线阵元，不同天线端口间的物理发射通道(即信道)可以认为互不相同，因此不同天线端口对应的时间误差也可以认为相互独立。一个天线面板包括多个天线阵元，一个天线端口对应天线面板中的一个或多个天线阵元。
在本申请实施例中，在不同的天线端口上发送的定位参考信号认为是不同的定位参考信号。示例性的，若定位参考信号为SRS，SRS资源为2天线端口的SRS资源，参见图3，SRS资源中的SRS时频资源中一部分为天线端口1对应的时频资源，另一部分为天线端口2对应的时频资源，则在天线端口1和天线端口2上发送的SRS可以认为是不同的SRS。需要说明的是，图3中以2个天线端口对应的时频资源不同为例进行描述，在实际实现时，2个天线端口对应的时频资源也可以相同，此时，可以通过码域资源区分不同的天线端口上发送的SRS。以上是对本申请涉及到的部分概念所作的简单介绍。
基于对上述时间误差的理解，终端设备在多天线面板场景下，以不同的天线端口发送定位参考信号时，不同的接入网设备测量得到的TOA之间会存在不同的时间误差，而基于TOA对终端设备进行定位时的定位精度依赖于TOA的估计准确度，TOA的估计准确度受限，导致终端设备的定位精度也受限。示例性的，若服务接入网设备指示终端设备在t1发送定位参考信号，终端设备通过天线端口1、天线端口2和天线端口3发送定位参考信号。其中，天线端口1的时间误差为1ns-2ns，天线端口2的时间误差为2ns-3ns，天线端口3的时间误差为0-1ns，定位参考信号在空间传输的时间为0.5ms，则接入网设备1接收到终端设备在天线端口1发送的定位参考信号的时间范围为：t1+1ns+0.5ms至t1+2ns+0.5ms，接入网设备2接收到终端设备在天线端口2发送的定位参考信号的时间范围为：t1+2ns+0.5ms至t1+3ns+0.5ms，接入网设备3接收到终端设备在天线端口3发送的定位参考信号的时间范围为：t1+0.5ms至t1+1ns+0.5ms。此时，接入网设备1认为定位参考信号在空间传输了1ns+0.5ms至2ns+0.5ms，接入网设备2认为定位参考信号在空间传输了2ns+0.5ms至3ns+0.5ms，接入网设备3认为定位参考信号在空间传输了0.5ms至1ns+0.5ms。实际上，定位参考信号在空间传输的时间均为0.5ms。
由于终端设备的位置或者朝向可能发生变化，因此在终端设备的定位过程中，终端设备可能通过不同的天线面板向同一个接入网设备发送参考信号。即参考信号与天线面板之间的关联关系发生变化，进一步的，该参考信号与时间误差的关联关系发生变化。而网络侧(接入网设备和定位服务器)无法感知该变化，依然使用该参考信号所关联的错误的时间误差对终端设备进行定位，进而导致定位精度降低。
基于此，本申请实施例提出一种时间误差信息的更新方法，终端设备向网络设备发送第一关联关系，和/或第一指示信息，所述第一关联关系包括时间误差信息与定位参考信号的关联关系，所述时间误差信息用于指示所述终端设备发送所述定位参考信号的时间误差，所述第一指示信息指示所述第一关联关系是否会动态变化和/或是否支持更新上报。通过上述方法，网络设备可以及时获知终端设备的定位参考信号与时间误差的关联关系，并且，网络设备还可以获知该定位参考信号与时间误差之间的关联关系是否会动态变化和/或是 否支持更新上报。使得网络设备可以使用精度更高的与定位参考信号关联的时间误差进行定位测量，提升了定位精度。
下面，结合附图说明本申请实施例，可以理解的是，本申请实施例涉及的定位参考信号还可以是PRS、信道状态信息参考信号、或者跟踪参考信号等，此处不作限制。示例性的，对于上行定位测量，定位参考信号可以是SRS；对于下行定位测量，定位参考信号可以是PRS。在本申请实施例中，以定位参考信号为SRS为例进行说明。
请参阅图4，图4为本申请实施例提出的一种时间误差信息的更新方法的实施例示意图。本申请实施例提出的一种时间误差信息的更新方法包括：
401、网络设备向终端设备发送定位能力请求消息。
401-402为可选。网络设备(例如定位服务器收到终端设备的定位请求后)向终端设备发送定位能力请求消息。该定位能力请求消息指示终端设备上报自身支持的定位能力信息。
示例性的，网络设备(例如定位服务器)通过LPP协议的消息向终端设备发送该定位能力请求消息。例如：通过LPP能力请求消息(LPP Request Capability)向终端设备发送该定位能力请求消息。
402、终端设备向网络设备发送定位能力信息。

示例性的，该定位能力信息包括终端设备支持时间误差信息测量的频点信息，例如n1、n2、n4和n38频点，在上述频点中终端设备支持时间误差信息测量。
又一种示例中，所述终端设备在各个频点支持的所述时间误差信息的数量，例如：以n38频点为例，该n38频点中，终端设备支持时间误差信息的数量为3，即终端设备支持获得的时间误差信息为3，例如“TEG1、TEG2和TEG3”。
又一种示例中，所述终端设备支持的最大的所述时间误差信息的数量，例如：终端设备中支持n1、n2、n4和n38频点的时间误差信息的测量，而n1中支持的时间误差信息的数量为2、n2中支持的时间误差信息的数量为3、n4中支持的时间误差信息的数量为1、n38中支持的时间误差信息的数量为5，则终端设备支持的最大的所述时间误差信息的数量为2+3+1+5＝11。
又一种示例中，定位能力信息包括：所述定位参考信号与所述时间误差信息关联关系是否支持更新上报或者动态检测。具体的，当定位能力信息包括所述定位参考信号与所述时间误差信息关联关系不支持更新上报，则终端设备上报的第一关联关系为静态的或者不会发生更新；当定位能力信息包括所述定位参考信号与所述时间误差信息关联关系支持更 新上报，则终端设备上报的第一关联关系为动态的或者会发生更新。
在一种可能的实现方式中，当网络设备(例如定位服务器)通过LPP协议的消息向终端设备发送该定位能力请求消息，终端设备通过LPP协议的消息向网络设备发送该定位能力信息。例如：终端设备通过LPP能力提供消息“LPP Provide capability”向定位服务器发送该定位能力信息。
需要说明的是，本申请实施例中不对承载定位能力请求消息和定位能力信息的消息类型进行限定。
可以理解的是，当401-402不执行时，终端设备与网络设备按照预先协商好的规则确定定位能力。例如：终端设备在入网时向网络设备上报自身的定位能力。
403、终端设备接收来自网络设备的第一请求消息或者第二请求消息。
403为可选。当403不执行时，终端设备可以根据预配置的信息或者根据协议约定向网络设备发送一组或多组第一关联关系和/或第一指示信息。
403中，网络设备可以是接入网设备，则终端设备接收来自接入网设备的第一请求消息。网络设备也可以是定位服务器，则终端设备接收来自定位服务器的第二请求消息。
第一请求消息与第二请求消息的用途类似，第一请求消息指示终端设备向接入网设备发送一组或多组第一关联关系和/或第一指示信息；第二请求消息指示终端设备向定位服务器发送一组或多组第一关联关系和/或第一指示信息。
具体的，所述终端设备接收来自所述接入网设备的第一请求消息，所述第一请求消息指示所述终端设备发送所述第一关联关系；所述终端设备根据所述第一请求消息向所述接入网设备发送所述第一关联关系和所述第一指示信息。
在一种可能的实现方式中，接入网设备触发终端设备上报第一关联关系和/或第一指示信息。
在另一种可能的实现方式中，接入网设备接收定位服务器的指示后，进一步指示终端设备上报第一关联关系和/或第一指示信息。
示例性的，第一请求消息可以携带在定位参考信号的配置信息中，或者，第一请求消息与定位参考信号的配置信息一同下发至终端设备。该第一请求消息可以是通过RRC信令下发至终端设备。RRC信令例如：SRS重配置消息(SRS Reconfiguration Message)。
在又一种示例中，接入网设备收到定位服务器的第三请求消息，该第三请求消息指示接入网设备向终端设备发送第一请求消息。示例性的，该第三请求消息可以是NR定位协议A(NRPPa)消息，例如：NR定位协议A定位信息请求消息“NRPPa positioning information Request”。
具体的，所述终端设备接收来自所述定位服务器的第二请求消息，所述第二请求消息指示所述终端设备发送所述第一关联关系；所述终端设备根据所述第二请求消息向所述定位服务器发送所述一组或多组第一关联关系和所述第一指示信息。具体的，可以通过接入 网设备转发上述一组或多组第一关联关系和第一指示信息。
示例性的，第二请求消息可以是LPP消息，或者其它消息。例如：LPP定位信息请求消息“LPP RequestLoccationInformation”。
该第一请求消息、第二请求消息或者第三请求消息，还可以用于请求终端设备上报不同粒度的第一关联关系，即第一关联关系中的时间误差信息的粒度不同。例如：
该第一请求消息(或者第二请求消息或者第三请求消息)，还可以用于请求终端设备上报发送所述定位参考信号的端口与所述时间误差信息的关联关系，一个或多个该端口由该第一请求消息(或者第二请求消息或者第三请求消息)指示。例如，第一请求消息(或者第二请求消息或者第三请求消息)指示终端设备上报端口1、3和5对应的定位参考信号与时间误差信息的关联关系。
该第一请求消息(或者第二请求消息或者第三请求消息)，还可以用于请求终端设备上报承载所述定位参考信号的资源与所述时间误差信息的关联关系，该资源由第一请求消息(或者第二请求消息或者第三请求消息)指示。例如，第一请求消息(或者第二请求消息或者第三请求消息)指示终端设备上报资源1、3和5对应的定位参考信号与时间误差信息的关联关系。上述资源1、3和5用于承载定位参考信号。
该第一请求消息(或者第二请求消息或者第三请求消息)，还可以用于请求终端设备上报承载所述定位参考信号的资源集与所述时间误差信息的关联关系，该资源集由第一请求消息(或者第二请求消息或者第三请求消息)指示。例如，第一请求消息(或者第二请求消息或者第三请求消息)指示终端设备上报资源集1、3和5对应的定位参考信号与时间误差信息的关联关系。上述资源集1、3和5用于承载定位参考信号。
该第一请求消息(或者第二请求消息或者第三请求消息)，还可以用于请求终端设备上报特定时间窗内的定位参考信号与时间误差信息的关联关系。例如：第一请求消息(或者第二请求消息或者第三请求消息)指示终端设备上报时间窗(10-50秒)内定位参考信号与时间误差信息的关联关系。时间窗还可以称为时间范围，或者时间段等，此处不作限制。
404、终端设备接收来自网络设备的第一配置信息。
404中，当网络设备为接入网设备时，终端设备接收来自接入网设备的第一配置信息，该第一配置信息指示终端设备当检测到第一关联关系更新或者发生变化后，向接入网设备发送更新后的第一关联关系或者发生变化后的第一关联关系。进一步的，接入网设备收到该更新后的第一关联关系或者发生变化后的第一关联关系，接入网设备可以向定位服务器发送该更新后的第一关联关系或者发生变化后的第一关联关系。
可选的，第一配置信息还可以指示终端设备当第一关联关系失效时，例如第一关联关系中时间误差的时间窗结束(或者过期)，终端设备向网络设备发送新的第一关联关系。
可选的，第一配置信息还可以指示终端设备周期性上报第一关联关系。例如每隔100秒上报一次第一关联关系。可选的，此时当第一关联关系为静态则不上报，或者，无论第一关联关系是否为静态或者动态(即第一关联关系是否更新支持上报)终端设备都会根据 第一配置信息的指示周期性上报该第一关联关系。
在另一种可能的实现方式中，终端设备也可以向定位服务器发送更新后的第一关联关系或者发生变化后的第一关联关系。
示例性的，该第一配置信息可以是接入网设备向终端设备配置定位参考信号的信息时一同配置的，例如：接入网设备向终端设备发送RRC信令，该RRC信令包括SRS重配置消息，该RRC信令用于向配置终端设备该定位参考信号。该RRC信令还包括第一配置信息。
在又一种示例中，接入网设备可以单独向终端设备发送该第一配置信息。例如通过RRC信令向终端设备发送该第一配置信息。
需要说明的是，404为可选。当404不执行时，终端设备可以根据第一指示信息确定是否发送第一关联关系。例如：当第一指示信息指示第一关联关系为动态的或者支持更新上报，则第一关联关系发生变化或者更新后，终端设备向网络设备发送第一关联关系。
405、终端设备接收来自网络设备的第二配置信息。
405中，与404是类似的，当执行404则不执行405，当执行405则不执行404。
当网络设备为定位服务器时，终端设备接收来自定位服务器的第二配置信息，该第二配置信息指示终端设备当检测到第一关联关系更新或者发生变化后，向接入网设备发送更新后的第一关联关系或者发生变化后的第一关联关系。进一步的，接入网设备收到该更新后的第一关联关系或者发生变化后的第一关联关系，接入网设备可以向定位服务器发送该更新后的第一关联关系或者发生变化后的第一关联关系。
或者，终端设备当检测到第一关联关系更新或者发生变化后，终端设备根据第二配置信息向定位服务器发送该更新后的第一关联关系或者发生变化后的第一关联关系。终端设备也可以通过接入网设备转发上述更新后的第一关联关系或者发生变化后的第一关联关系。
可选的，第二配置信息还可以指示终端设备当第一关联关系失效时，例如第一关联关系中时间误差的时间窗结束(或者过期)，终端设备向网络设备发送新的第一关联关系。
示例性的，该第二配置信息可以承载于定位服务器向终端设备发送的：LPP定位信息请求消息“LPP RequestLoccatonInfo”中。该LPP定位信息请求消息也可以由接入网设备转发至终端设备。
需要说明的是，405为可选。当405不执行时，终端设备可以根据第一指示信息确定是否发送第一关联关系。例如：当第一指示信息指示第一关联关系为动态的或者支持更新上报，则第一关联关系发生变化或者更新后，终端设备向网络设备发送第一关联关系。
406、终端设备向网络设备发送第一关联关系和/或第一指示信息。
406中，具体的，第一关联关系包括：时间误差信息和定位参考信号的关联关系。时间误差信息用于指示终端设备发送定位参考信号的时间误差。
示例性的，以定位参考信号为SRS，时间误差信息为TEG的大小为例，第一关联关系 还可以表示“SRS-TEG”或者“SRS-TEG的关联关系”。第一指示信息可以指示第一关联关系为动态或者静态，即“SRS-TEG”为动态或者静态，或者“SRS-TEG的关联关系”为动态或者静态。
在一种可能的实现方案中，如果SRS-TEG的关联关系是静态的，支持终端将SRS-TEG的关联关系上报给服务基站，服务基站再将关联关系转发给定位服务器。
“Support UE to provide the SRS-TEG association to gNB and gNB forward the association to LMF if the association is static.”
在另一种可能的实现方案中，如果SRS-TEG的关联关系是动态的，支持终端将SRS-TEG的关联关系直接上报给定位服务器。在这种情况下，终端将第一指示信息(指示动态的SRS-TEG的关联关系的指示信息)上报给服务基站，服务基站再将该第一指示信息(指示动态的SRS-TEG的关联关系的指示信息)上报给定位服务器。
“Support UE to provide the SRS-TEG association directly to LMF per LMF request if the association is dynamic.”
下面进行详细描述：对于SRS-TEG关联关系的上报方式，有两个选项在上次会议达成的一致。选项1，终端直接上报SRS-TEG的关联关系给LMF；选项2，终端上报SRS-TEG的关联关系给gNB，然后gNB转发关联关系给LMF。
因此，SRS-TEG的关联关系的上报方式取决于SRS-TEG的特性。如果SRS-TEG的关联关系是静态的，那么终端可以在SRS的配置阶段，通过RRC信令将SRS-TEG的关联关系上报给服务基站。然后服务基站将关联关系与定位信息一起通过NRPPa信令上报给定位服务器。SRS-TEG的静态特性的指示信息可以与关联关系一起，通过RRC+NRPPa信令上报给定位服务器。定位服务器知道该终端的SRS-TEG的关联关系是静态的，因此在后续的过程中不会要求服务基站或者终端更新该关联关系。因此，系统的信令开销可以得到有效降低(有益效果可以添加到说明书中：如果定位服务器不知道静态特性，后续发起上报请求，终端再通过信令上报，但是上报内容都是一样的，因此会导致不必要的信令开销。通过指示信息上报，可以避免上述情况，降低开销，提升系统效率)。此外，在上行定位方法中，终端不强制要求支持LPP信令，因此终端可能无法通过LPP信令上报SRS-TEG的关联关系。通过RRC上报关联关系能够维持终端的能力和特性不变，降低对终端的能力要求(有益效果)。
如果SRS-TEG的关联关系是动态的，意味着SRS-TEG的关联关系在将来SRS的传输阶段可能会发生变化。在这种情况下，在需要的时候，定位服务器可能会直接通过LPP信令要求终端上报更新的SRS-TEG的关联关系。为了使能定位服务器通过LPP信令直接向终端请求SRS-TEG的关联关系，可以通过RRC+NRPPa信令将动态特性的指示信息在SRS的初始配置阶段和定位信息的交互阶段上报给定位服务器。
对于通过RRC消息上报SRS-TEG的关联关系，同时携带静态指示信息，或者动态指示信息指示可以通过LPP信令进一步上报更新的的关联关系，我们认为RRC重配置完成消息(RRCReconfigurationComplete)是承载SRS-TEG关联关系的首选，从而服务基站可以及时的再通过NRPPa定位信息交换消息将关联关系或者指示信息上报给定位服务器。
“For the reporting of the SRS-TEG association,based on the agreement there are two options.In option 1,UE reports the SRS-TEG association to LMF directly.In option 2,the UE reports the SRS-TEG association to gNB and gNB forwards the association to the LMF.
In our opinion,the reporting of the SRS-TEG association depends on the characteristics of the Tx TEG.In the case that the Tx TEG is static,the SRS-TEG association can be provided to the gNB during the SRS configuration procedures via RRC signaling and the gNB can forward it to the LMF along with the positioning information via NRPPa.The indication of static characteristic can be reported along with the association via RRC+NRPPa path.The LMF is aware of this characteristic and will not request the gNB or UE to update the association.Hence,the signaling overhead can be saved.In addition,for UL positioning methods,UE is not required to support LPP,and reporting SRS-TEG association via RRC may still maintain the property for the UE.
In the case that the Tx TEG is dynamic,which means the SRS-TEG association might change during the SRS transmission.In this case,the LMF might request the UE to provide the association when it is needed via the LPP path.To enable the LMF request the UE to report the SRS-TEG association in LPP,indication of dynamic characteristic should be supported via RRC+NRPPa path during the initial SRS configuration and positioning information exchange procedures.
For the RRC message to contain either the SRS-TEG association with indication of static characteristics or the indication of dynamic characteristics that implies further update to be provided by LPP,we assume RRCReconfigurationComplete message should be a natural choice so that gNB can feedback the association timely to the LMF in the NRPPa POSITIONING INFORMATION RESPONSE message.”
示例性的，第一关联关系如表2所示，以定位参考信号为SRS，时间误差信息为时间误差的大小，时间误差为TEG为例。需要说明的是，本申请实施例中，以“SRS ID1”为例，“SRS ID1”示意的是标识(或者索引)为“SRS ID1”的定位参考信号。

可选的，时间误差信息还可以是时间误差的范围，则第一关联关系如表4所示：
表4
Figure PCTCN2022106931-appb-000004
进一步的，第一关联关系还可以包括时间误差的时间窗，该时间误差的时间窗指示时间误差与定位参考信号存在关联关系的时间范围。该时间窗还可以理解为该时间误差的有效时间，在该有效时间内，该时间误差与定位参考信号之间具有关联关系。示例性的，第一关联关系如表5所示：
表5
Figure PCTCN2022106931-appb-000005
表5中，以定位参考信号为SRS ID1为例，在时间误差的时间窗[0-5)秒内，SRS ID1具有关联关系的时间误差信息为TEG1，在时间误差的时间窗[5-15)秒内，SRS ID1具有关联关系的时间误差信息为TEG2。
可以理解的是，时间误差的时间窗除了包括未来的时间窗(即该时间窗指示未来一段时间，该时间窗内定位参考信号与时间误差信息具有关联关系)，时间误差的时间窗还可以 包括过去的时间窗。过去的时间窗指的是在过去的一段时间内，该时间窗内的定位参考信号与时间误差信息具有关联关系。例如：第一关联关系包括时间误差的时间窗“(-10,0](秒)”，SRS ID1和TEG1，该第一关联关系指示在过去的0-10秒，SRS ID1与TEG1具有关联关系。
在又一种示例中，第一关联关系包括时间误差的时间窗“09时10分20秒至09时20分20秒”，SRS ID1和TEG1，该第一关联关系指示在09时10分20秒至09时20分20秒这一时间段内，SRS ID1与TEG1具有关联关系。
进一步的，第一关联关系可以是定位参考信号与时间误差信息的关联关系。第一关联关系还可以是定位参考信号的端口(例如是SRS port)与时间误差信息的关联关系。第一关联关系还可以是定位参考信号的资源(例如承载SRS的资源(resource))与时间误差信息的关联关系。第一关联关系还可以是定位参考信号的资源集(例如：承载SRS的资源集(resource sets))与时间误差信息的关联关系。需要说明的是，第一关联关系还可以是承载定位参考信号的其它粒度的资源与时间误差信息的关联关系，第一关联关系还可以是发送定位参考信号的天线面板或者射频链路与时间误差信息的关联关系，此处不作限制。
例如：第一关联关系为某一个或多个频点的定位参考信号与时间误差信息的关联关系。
第一指示信息指示第一关联关系是否会动态变化和/或是否支持更新上报。
具体的，第一指示信息第一关联关系是否会动态变化，例如：第一指示信息指示第一关联关系为动态，则该第一关联关系会动态发生变化；第一指示信息指示第一关联关系为静态，则该第一关联关系不会发生变化。第一关联关系为动态，也可以理解为第一关联关系会更新，终端设备会向网络设备上报更新后的第一关联关系或者发生变化后的第一关联关系。
第一指示信息指示第一关联关系是否支持更新上报，例如：第一指示信息指示第一关联关系支持更新上报，则终端设备中第一关联关系发生变化或者更新后，终端设备向网络设备上报该发生变化或者更新后的第一关联关系。第一指示信息指示第一关联关系不支持更新上报，则终端设备中该第一关联关系不会发生变化或者更新，或者，终端设备中该第一关联关系即使发生变化或者更新，终端设备也不会向网络设备上报该发生变化或者更新的第一关联关系。
示例性的，第一指示信息指示第一关联关系为静态，则第一指示信息可以是“static”；第一指示信息指示第一关联关系为动态，则第一指示信息可以是“dynamic”。
在又一种示例中，第一指示信息指示第一关联关系为静态，则第一指示信息可以是“1”；第一指示信息指示第一关联关系为动态，则第一指示信息可以是“0”。
在一种可能的实现方式中，当第一关联关系为静态(或者第一关联关系不会发生更新或者变化)，终端设备向网络设备仅发送第一关联关系。
在另一种可能的实现方式中，当终端设备需要发送定位参考信号后才能确定该定位参考信号对应的时间误差信息时，终端设备可以首先向网络设备仅发送第一指示信息。该第一指示信息指示关联的第一关联关系为静态或者动态。当终端设备发送定位参考信号后，终端设备确定该定位参考信号对应的时间误差信息，终端设备进而确定实际的第一关联关 系。终端设备确定实际的第一关联关系后，终端设备向网络设备发送该第一关联关系。网络设备收到该第一关联关系后，根据之前收到的第一指示信息确定该第一关联关系是动态的还是静态的。
示例性的，终端设备可以向网络设备仅发送第一指示信息，当终端设备向网络设备仅发送第一指示信息时，第一指示信息还可以指示第一关联关系为动态“Dynamic”，静态“Static”，或者未知“unknown”，上述第一指示信息均可指示当前无法获取第一关联关系，终端设备需要向网络设备发送定位参考信号后，确定定位参考信号对应的时间误差信息，进而确定第一关联关系，即该定位参考信号与时间误差信息之间的关联关系。终端设备向网络设备发送该第一关联关系。可选的，终端设备向网络设备发送该第一关联关系时，终端设备同时向网络设备发送更新的第一指示信息，该更新的第一指示信息指示第一关联关系是否会动态变化和/或是否支持更新上报。
在另一种可能的实现方式中，终端设备向网络设备同时发送第一关联关系和第一指示信息。这里的“同时”可以理解为终端设备在同一条信令中向网络设备发送第一关联关系和第一指示信息，也可以理解为终端设备在时间上相邻的两条或多条信令中分别向网络设备发送第一关联关系和指示信息，此处不做限制。
示例性的，终端设备向网络设备同时发送第一关联关系和第一指示信息，例如表6所示：
表6
Figure PCTCN2022106931-appb-000006
表6中，以定位参考信号为SRS ID1为例，第一关联关系包括定位参考信号(SRS ID1)、时间误差信息(TEG1)和时间误差的时间窗“[time1,time2]”。该时间误差的时间窗指示定位参考信号SRS ID1在[time1,time2]时间段内与时间误差信息TEG1存在关联关系，或者定位参考信号SRS ID1在[time1,time2]时间段内的时间误差为TEG1。该第一指示信息指示该第一关联关系为静态的，即不支持更新上报。
需要说明的是，时间误差的时间窗还可以是其它实现方式，例如：时间误差的时间窗为“time1”，“time1”指示time1时刻前后100秒内，第一关联关系中定位参考信号与时间误差信息存在关联关系。即time1时刻前后100秒内，第一关联关系有效。

在又一种示例中，第一关联关系和第一指示信息，如表8所示：
表8

进一步的，终端设备可以通过多种信令或者消息向网络设备发送第一关联关系和/或第一指示信息。包括但不限于：无线资源控制(radio resource control，RRC)消息、媒体接入控制元素(media access control control element，MAC CE)消息或者LTE定位协议消息。
示例性的，终端设备可以通过RRC辅助(RRC assistant information)信令向网络设备发送第一关联关系和/或第一指示信息。
又一种示例中，终端设备可以通过RRC注册完成(RRC reconfiguration complete)信令向网络设备发送第一关联关系和/或第一指示信息。

当网络设备接收该第一关联关系后，若该第一关联关系为动态的或者支持更新的，则网络设备使用该第一关联关系替换本地的第一关联关系。网络设备根据该第一关联关系和接入网设备收到的来自终端设备的定位参考信号，对终端设备进行定位测量。

需要说明的是，当终端设备仅发送第一指示信息时，需要在507终端设备向接入网设备发送定位参考信号后，确定第一关联关系。则507后，终端设备向接入网设备发送该第一关联关系。具体发送流程与505-506一致，此处不作赘述。
506、接入网设备向定位服务器发送第一关联关系和/或第一指示信息。

示例性的，终端设备可以通过“RRC Assistant Information”信令或者，MAC CE信令向接入网设备发送该更新后的第一关联关系。

本实施例中，终端将定位参考信号与时间误差信息的关联关系上报给基站，基站再将该关联关系转发给定位服务器的方式，实现关联关系的上报。在该实施例中，一旦检测到本地发射定位参考信号的天线面板发生切换导致所关联的时间误差信息发生变化，终端立即以辅助信息更新的形式将发生变化的关联关系上报给服务基站。服务基站收到更新的关联关系，通过NRPPa定位信息更新的形式，将关联关系转发给定位服务器LMF。终端在上报关联关系的同时，包含指示信息，指示该关联关系是动态的还是静态的，并指示该关联关系的生效时间，以及有效时间等。通过上述以辅助信息更新的形式上报定位参考信号与时间误差信息的关联关系，即可达到动态更新定位参考信号与时间误差信息关联关系的效果，提升定位精度。

608、定位服务器向终端设备发送第二请求消息。
608中，当定位服务器根据第一指示信息确定606收到的第一关联关系发生变化或者发生更新，或者，定位服务器在对终端设备的定位测量中发现606收到的第一关联关系的误差较大，则定位服务器向终端设备发送第二请求消息，该第二请求消息用于指示终端设备向定位服务器发送第一关联关系。由于该第一关联关系可能与605中发送的第一关联关系不一致，因此将终端设备响应于608的第二请求消息发出的第一关联关系称为更新后的第一关联关系。
具体的，定位服务器向终端设备发送第二请求消息与前述403类似。示例性的，第二请求消息可以是LPP消息，或者其它消息。例如：LPP定位信息请求消息“LPP RequestLocationInformation”。
可以理解的是，608可以发生于602后的任意时刻，此处不作限制。

可选的，终端设备还可以向定位服务器发送第一指示信息。
示例性的，609中，终端设备通过LPP消息向定位服务器发送第一关联关系。例如，通过“LPP ProvideLocationInformation”消息发送第一关联关系。
本实施例中，终端在配置完定位参考信号资源之后，将初始的定位参考信号与时间误差信息的关联关系上报给服务基站，其中包含指示信息，再由服务基站转发给定位服务器。定位服务器收到关联关系之后，根据关联关系的指示信息，判断是否需要终端上报更新的关联关系，如果上报的是静态的关联关系，则定位服务器无需通过高层信令请求关联关系。如果是动态的，并且已经失效，那么定位服务器可通过高层信令，直接请求上报更新的关联关系。如果关联关系是周期性变化的，那么定位服务器可配置终端周期性的上报更新的关联关系。通过该实施例，定位服务器能够根据关联关系的指示信息或者定位结果等向终 端请求特定资源和特定时间窗的关联关系，解决关联关系动态变化的问题。
