应当理解的是，本公开并不局限于上面已经描述并在附图中示出的精确结构，并且可以在不脱离其范围进行各种修改和改变。本公开的范围仅由所附的权利要求来限制。
首先，对本公开实施例涉及的相关名词进行介绍：
对A-GNSS的定位完整性进行介绍：
对于定位技术，NR中引入了定位完整性(positioning integrity)的概念。定位完整性用于衡量定位系统提供的位置相关数据的准确性的可信度，以及在定位系统不满足预定操作条件时，向定位服务(Location Service，LCS)客户提供及时有效警告的能力。
目前已标准化了针对A-GNSS定位技术的定位完整性。主要包括：LMF向终端设备提供错误源(辅助信息)的完整性参数。示例性地，表1示出了该完整性参数的映射(mapping of integrity parameters)。
表1
Figure PCTCN2022111268-appb-000001
Figure PCTCN2022111268-appb-000002
Figure PCTCN2022111268-appb-000003
终端设备根据上述参数能够确定A-GNSS的定位完整性，并向LMF上报定位完整性的确定结果。
相关技术仅提供了基于A-GNSS的定位完整性的确定方式。目前，正在研究基于RAT(RAT-dependent)的定位技术的定位完整性问题。例如上行链路(Uplink，UL)UL-到达时间差(Time Difference Of Arrival，TDOA)，下行链路(Downlink，DL)-TDOA，UL-到达角(Angle-Of-Arrival，AOA)，DL-出发角(Angle-Of-Departure，AOD)等定位技术的定位完整性问题。可选地，在本公开实施例中，RAT-dependent定位技术包括上行定位或上行和下行相结合的定位。对于确定RAT-dependent定位技术的定位完整性的具体实现，还需要进一步讨论研究。
本公开实施例提供的方法，提供了在下行定位或上行和下行相结合的定位中，实现终端设备和LMF之间交互错误源信息的方式。根据该错误源信息，可以使得终端设备或LMF确定下行定位或上行和下行相结合的定位的定位完整性，从而提供了确定RAT-dependent定位技术的定位完整性的实现方式。
图1是本公开一个示例性实施例示出的通信系统的示意图。该通信系统100可以包括：终端设备101、接入网设备102和核心网设备103。
终端设备101的数量通常为多个，每一个接入网设备102所管理的小区内可以分布一个或多个终端设备101。终端设备101可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本公开实施例中，上面提到的设备统称为终端设备。
接入网设备102是一种部署在接入网中用以为终端设备101提供无线通信功能的装置。接入网设备102可以包括各种形式的宏基站，微基站，中继站，接入点。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，例如在第五代(5th Generation，5G)移动通信技术NR系统中，称为gNodeB或者gNB。一个接入网设备可以包含至少一个TRP(Transmission Reception Point，发送接收点)。在一些实施例中，接入网设备12还可以是指TRP。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本公开实施例中，上述为终端设备101提供无线通信功能的装置统称为接入网设备。接入网设备102与终端设备101之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。接入网设备102的数量可以有多个，两个邻近的接入网设备102之间也 可以通过有线或者无线的方式进行通信。终端设备101可以在不同的接入网设备102之间进行切换，也即与不同的接入网设备102建立连接。
核心网设备103的功能主要是提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。接入网设备102和核心网设备103可统称为网络设备。核心网设备103与接入网设备102之间通过某种空中技术相互通信，通过接入网设备102，终端设备101和核心网设备103之间可以建立通信关系。示例性地，本公开实施例中的核心网设备指LMF。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
图2是根据一示例性实施例示出的一种错误源信息的发送方法的流程图，本实施例以该错误源信息的发送方法由图1所示通信系统中的接入网设备执行来举例说明。该方法可以包括如下步骤210。
在步骤210中，向LMF发送定位的错误源信息。
其中，定位包括上行定位或上行和下行相结合的定位。例如，定位是指基于UL-TDOA或UL-AOA或多往返时间(multi-Round Trip Time，multi-RTT)的定位。其中，基于multi-RTT的定位是上行和下行相结合的定位。错误源信息用于LMF确定该定位的定位完整性。
在一些实施例中，本公开实施例中提及的“错误”，也可以称为“误差”、“偏差”等。例如，错误源也可以称为误差源、偏差源；错误源信息也可以称为是误差源信息、偏差源信息；错误信息也可以称为误差信息、偏差信息。需要理解的是，错误源信息中包含的信息，可以包括允许的误差范围内的误差或错误信息(属于误差范围内、且仍然可用或可信任的误差或错误信息，或这些信息的来源)，也可以包括允许的误差范围之外的误差或错误信息(即误差较大以至于不可用或不可信的信息，或这些信息的来源)。
在一些实施例中，定位完整性包括以下至少之一：
·定位系统提供的位置信息的准确性的可信度；
·在定位系统不满足预定操作条件时，发送有效警告的能力。
其中，定位系统是进行上述定位的系统，定位系统可以包括LMF、终端设备和接入网设备中的一种或多种设备。定位完整性用于衡量定位系统提供的位置信息的准确性的可信度，和/或，用于衡量在定位系统不满足预定操作条件时，向LCS客户发送有效警告的能力。在一些实施例中，位置信息是与位置或定位相关的信息或数据。
在一些实施例中，定位完整性用于衡量定位系统提供的位置信息的准确性的可信度，也可以是指用于衡量对定位系统提供的位置信息的准确性的信任。在一些实施例中，不满足预定操作条件包括保护等级(Protection Level，PL)大于警戒限制(Alert Limit，AL)。其中，PL是根据错误源信息计算得到的，AL是预设的。AL是使定位系统能够用于预定应用的最大允许定位误差。
在一些实施例中，错误源信息包括以下至少一种：
·接入网设备的测量错误信息；
·接入网设备的位置错误信息；
·多个接入网设备之间的时间同步错误信息；
·接入网设备的定时错误信息；
·终端设备的错误信息。
在一些实施例中，接入网设备向LMF发送的错误源信息中，与接入网设备相关的错误源信息(如接入网设备的测量错误信息、接入网设备的位置错误信息、多个接入网设备之间的时间同步错误信息、接入网设备的定时错误信息)，是由接入网设备根据自身运行情况而自行生成的。在一些实施例中，与接入网设备不相关(或关联性较小)的错误源信息，是其他设 备发送给接入网设备的。例如，接入网设备显然无法直接获取终端设备的错误信息，终端设备的错误信息可以是由终端设备发送给接入网设备的。
在一些实施例中，接入网设备的测量错误信息，包括以下至少一种：
·接入网设备的接收发送时间差；
·RTOA(Relative Time of Arrival，相对到达时间)；
·AOA；
·SRS(Sounding Reference Signal，信道探测参考信号)-RSRP(Reference signal received power，参考信号接收功率)；
·SRS-RSRPP(Reference Signal Received Path Power，参考信号接收路径功率)的错误信息。
在一些实施例中，多个接入网设备之间的时间同步错误信息，可以指不同接入网设备之间需要尽可能实现时间同步时，出现的时间不同步的情况；相对到达时间包括：相对于参考时间，接入网设备接收到包含定位参考信号(如上行定位参考信号)的子帧的起始时间。其中，参考时间可以由LMF配置。
在一些实施例中，终端设备的错误信息包括以下至少一种：
·终端设备的测量错误；
·终端设备的定时错误；
·终端设备的波束或天线错误。
在一些实施例中，终端设备的测量错误包括终端设备在执行测量时产生的错误，包括终端设备测量定位参考信号时产生的错误。终端设备的定时错误包括与终端设备的定时相关的错误。例如，包括发射信号在终端设备的天线和基带之间的时间差，以及终端设备自身的时钟偏差，例如为终端设备的时钟相对于GNSS时间的差值。终端设备的波束或天线错误包括与终端设备收发的波束或终端设备的天线相关的错误。例如，包括终端设备使用的波束发送方向和实际发送方向之间的偏差。
在一些实施例中，终端设备的测量错误包括以下至少一种：
·终端设备的接收发送时间差；
·参考信号时间差(Reference Signal Time Difference，RSTD)；
·定位参考信号(Positioning Reference Signal，PRS)-RSRP；
·PRS-RSRPP。
在一些实施例中，接入网设备向LMF发送定位的错误源信息，包括：向LMF发送包含错误源信息的NRPPa(NR Positioning Protocol a，NR定位协议a)消息。也即，接入网设备向LMF发送NRPPa消息，该NRPPa消息中包含有错误源信息。在一些实施例中，包含错误源信息的NRPPa消息，为定位信息响应(positioning information response)或测量响应(measurement response)。
在一些实施例中，接收LMF发送的请求信息；其中，请求信息用于请求接入网设备发送错误源信息。接入网设备可以在接收到LMF发送的请求信息之后，响应于该请求信息，再向LMF发送其所请求的错误源信息。在一些实施例中，接入网设备可以主动向LMF发送错误源信息；或者，接入网设备发送的错误源信息，是基于LMF的请求信息发送的。在一些实施例中，接收LMF发送的包含请求信息的NRPPa消息。也即，接入网设备接收LMF发送的NRPPa消息，该NRPPa消息中包含有请求信息。显然，接入网设备发送的NRPPa消息和接收的NRPPa消息不相同，则接入网设备接收到的NRPPa消息和发送的NRPPa消息可以分别称为第一NRPPa消息和第二NRPPa消息，以示区分。在一些实施例中，包含错误源信息的NPPPa消息或包含请求信息的NRPPa消息，为定位信息请求(positioning information request)或测量请求(measurement request)。
在一些实施例中，向LMF发送错误源信息的DNU(Don’t Use，不使用)信息；其中，DNU信息用于指示LMF不使用错误源信息来确定定位的定位完整性。例如，接入网设备向 LMF发送了接入网设备的测量错误信息以及接入网设备的定时错误信息，由于接入网设备的测量值超出了正常数据的分布范围，接入网设备会向LMF发送该DNU信息，以指示LMF不使用接入网设备的测量错误信息来确定定位的定位完整性，可选地，这种情况下LMF可以使用接入网设备的定时错误信息来确定定位的定位完整性。
在一些实施例中，向终端设备发送错误源请求信息；其中，错误源请求信息用于请求终端设备发送错误源信息。之后，接入网设备接收终端设备发送的错误源信息。在一些实施例中，接收终端设备发送的错误源信息，包括：接收终端设备发送的包含错误源信息的消息，如RRC(Radio Resource Control，无线资源控制)消息。也即，接入网设备接收终端设备发送的消息，该消息中包含有错误源信息。从而可以将错误源信息与其他信息一同被携带在该消息中进行发送，从而减少了信息发送的次数，节省了终端设备的信令开销。
在一些实施例中，终端设备主动向接入网设备发送错误源信息；或者，终端设备基于接入网设备的错误源请求信息，向接入网设备发送错误源信息。
在一些实施例中，接收终端设备发送的能力信息；其中，能力信息用于指示终端设备支持发送的错误源信息。例如，在接入网设备向终端设备发送错误源请求信息之前，终端设备主动发送或基于接入网设备的请求发送能力信息，以使得接入网设备了解终端设备支持发送的错误源信息。终端设备也可以向接入网设备指示支持基于某种定位技术的定位完整性能力。例如，基于DL-TDOA、基于DL-AOD、基于multi-RTT、基于UL-TDOA、基于UL-AOA的定位技术。例如，终端设备向接入网设备上报支持基于某种定位技术定位完整性功能，则当使用某种定位技术对终端设备进行定位时可以请求终端设备上报对应该定位技术的错误源信息。
在一些实施例中，终端设备仅支持发送与其自身相关的错误源信息，如上述的终端设备的错误信息。终端设备可以不支持发送与终端设备无关的错误源信息，例如，终端设备不支持发送与接入网设备相关的错误源信息(如接入网设备的测量错误信息、接入网设备的位置错误信息、多个接入网设备之间的时间同步错误信息、接入网设备的定时错误信息等等)。接入网设备在获取了终端设备的能力信息之后，可以根据能力信息确定是否向终端设备请求错误源信息。例如，若根据能力信息了解到，终端设备不支持接入网设备所需要的错误源信息，则接入网设备就不会向终端设备发送错误源请求信息，从而节省信令开销，也减少了等待终端设备发送错误源信息所消耗的时间，提升接入网设备获取所需的错误源信息的效率。进一步地，接入网设备可以根据能力信息有针对性地向终端设备发送错误源请求信息，以向终端设备请求终端设备支持的错误源信息。在一些实施例中，错误源请求信息不会用于请求终端设备不支持发送的错误源信息。
综上所述，本公开实施例提供的技术方案中，通过由接入网设备向LMF发送定位的错误源信息，提供了在上行定位或上行和下行相结合的定位中，实现接入网设备和LMF之间交互错误源信息的方式；基于错误源信息，可以使LMF确定上行定位或上行和下行相结合的定位的定位完整性，从而提供了确定RAT-dependent定位技术的定位完整性的实现方式。
图3是根据一示例性实施例示出的一种错误源信息的接收方法的流程图，本实施例以该错误源信息的发送方法由图1所示通信系统中的LMF执行来举例说明。该方法可以包括如下步骤310。
在步骤310中，接收接入网设备发送的定位的错误源信息。
其中，定位包括上行定位或上行和下行相结合的定位。例如，定位是指基于UL-TDOA或UL-AOA或multi-RTT的定位。其中，基于multi-RTT的定位是上行和下行相结合的定位。错误源信息用于LMF确定该定位的定位完整性。
需要理解的是，错误源信息中包含的信息，可以包括允许的误差范围内的误差或错误信息(属于误差范围内、且仍然可用或可信任的误差或错误信息，或这些信息的来源)，也可以包括允许的误差范围之外的误差或错误信息(即误差较大以至于不可用或不可信的信息，或 这些信息的来源)。

在一些实施例中，终端设备的测量错误包括终端设备在执行测量时产生的错误，包括终端设备测量定位参考信号时产生的错误。终端设备的定时错误包括与终端设备的定时相关的错误。例如，包括发射信号在终端设备的天线和基带之间的时间差，以及终端设备自身的时钟偏差，例如为终端设备的时钟相对于GNSS时间的差值。终端设备的波束或天线错误包括与终端设备收发的波束或终端设备的天线相关的错误。例如，包括终端设备使用的波束发送方向和实际发送方向之间的偏差。
在一些实施例中，终端设备的测量错误包括以下至少一种：
·终端设备的接收发送时间差；
·RSTD；
·PRS-RSRP；
·PRS-RSRPP。
在一些实施例中，相对到达时间是指：相对于参考时间，接入网设备接收到包含定位参考信号(如上行定位参考信号)的子帧的起始时间。
在一些实施例中，接收接入网设备发送的定位的错误源信息，包括：接收接入网设备发 送的包含错误源信息的NRPPa消息。也即，接入网设备向LMF发送NRPPa消息，该NRPPa消息中包含有错误源信息。在一些实施例中，包含错误源信息的NRPPa消息，为定位信息响应或测量响应。
在一些实施例中，向接入网设备发送请求信息；其中，请求信息用于请求接入网设备发送错误源信息。也即，在一些实施例中，LMF若需要获取错误源信息，可以主动向接入网设备发送请求信息，以获取错误源信息。LMF接收到的错误源信息，可以是接入网设备主动发送的，也可以是接入网设备基于请求信息发送的。在一些实施例中，向接入网设备发送包含请求信息的NRPPa消息。也即，LMF向接入网设备发送NRPPa消息，该NRPPa消息中包含有请求信息。显然，LMF接收到的NRPPa消息和发送的NRPPa消息不相同，MF接收到的NRPPa消息和发送的NRPPa消息，可以分别称为第一NRPPa消息和第二NRPPa消息，以示区分。在一些实施例中，包含错误源信息的NPPPa消息或包含请求信息的NRPPa消息，为定位信息请求或测量请求。
在一些实施例中，接收接入网设备发送的错误源信息的DNU信息；其中，DNU信息用于指示LMF不使用错误源信息来确定定位的定位完整性。例如，LMF接收到接入网设备发送的接入网设备的测量错误信息以及接入网设备的定时错误信息，由于接入网设备的测量值超出了正常数据的分布范围，LMF会接收到接入网设备发送的DNU信息。接收到DNU信息之后，LMF按照DNU信息的指示，就不会使用接入网设备的测量错误信息来确定定位的定位完整性了。可选地，这种情况下LMF可以使用接入网设备的定时错误信息或其他错误源信息来确定定位的定位完整性。
综上所述，本公开实施例提供的技术方案中，通过LMF接收接入网设备发送的错误源信息，提供了在上行定位或上行和下行相结合的定位中，实现接入网设备和LMF之间交互错误源信息的方式；基于错误源信息，LMF能够确定上行定位或上行和下行相结合的定位的定位完整性，从而提供了确定RAT-dependent定位技术的定位完整性的实现方式。
图4是根据另一示例性实施例示出的一种错误源信息的发送方法的流程图，本实施例以该错误源信息的发送方法由图1所示通信系统中的终端设备执行来举例说明。该方法可以包括如下步骤410。
在步骤410中，向接入网设备发送定位的错误源信息。
其中，定位包括上行定位或上行和下行相结合的定位。例如，定位是指基于UL-TDOA或UL-AOA或multi-RTT的定位。其中，基于multi-RTT的定位是上行和下行相结合的定位。错误源信息用于LMF确定该定位的定位完整性。
需要理解的是，错误源信息中包含的信息，可以包括允许的误差范围内的误差或错误信息(属于误差范围内、且仍然可用或可信任的误差或错误信息，或这些信息的来源)，也可以包括允许的误差范围之外的误差或错误信息(即误差较大以至于不可用或不可信的信息，或这些信息的来源)。
在一些实施例中，定位完整性包括以下至少之一：
·定位系统提供的位置信息的准确性的可信度；
·在定位系统不满足预定操作条件时，发送有效警告的能力。
其中，定位系统是进行上述定位的系统，定位系统可以包括LMF、终端设备和接入网设备中的一种或多种设备。定位完整性用于衡量定位系统提供的位置信息的准确性的可信度，和/或，用于衡量在定位系统不满足预定操作条件时，向LCS客户发送有效警告的能力。在一些实施例中，位置信息是与位置或定位相关的信息或数据。
在一些实施例中，定位完整性用于衡量定位系统提供的位置信息的准确性的可信度，也可以是指用于衡量对定位系统提供的位置信息的准确性的信任。在一些实施例中，不满足预定操作条件包括PL大于AL。其中，PL是根据错误源信息计算得到的，AL是预设的。AL是使定位系统能够用于预定应用的最大允许定位误差。
在一些实施例中，终端设备向接入网设备发送的错误源信息，包括终端设备的错误信息。

在一些实施例中，终端设备的测量错误包括以下至少一种：
·终端设备的接收发送时间差；

·PRS-RSRP；
·PRS-RSRPP。
在一些实施例中，接收接入网设备发送的错误源请求信息；其中，错误源请求信息用于请求终端设备发送错误源信息。在一些实施例中，终端设备可以主动向接入网设备发送错误源信息(如终端设备的错误信息)；也可以在接收到接入网设备发送的错误源请求信息之后，基于错误源请求信息向接入网设备发送错误源信息。
在一些实施例中，向接入网设备发送包含错误源信息的消息，如RRC消息。也即，终端设备向接入网设备发送消息，该消息中包含有错误源信息。从而可以将错误源信息与其他信息一同被携带在该消息中进行发送，从而减少了信息发送的次数，节省了终端设备的信令开销。
在一些实施例中，向接入网设备发送能力信息；其中，能力信息用于指示终端设备支持发送的错误源信息。例如，在终端设备接收到接入网设备发送的错误源请求信息之前，终端设备主动发送或基于接入网设备的请求发送能力信息，以使得接入网设备了解终端设备支持发送的错误源信息。
在一些实施例中，终端设备仅支持发送与其自身相关的错误源信息，如上述的终端设备的错误信息。终端设备可以不支持发送与终端设备无关的错误源信息，例如，终端设备不支持发送与接入网设备相关的错误源信息(如接入网设备的测量错误信息、接入网设备的位置错误信息、多个接入网设备之间的时间同步错误信息、接入网设备的定时错误信息等等)。接入网设备在获取了终端设备的能力信息之后，可以根据能力信息确定是否向终端设备请求错误源信息。例如，若根据能力信息了解到，终端设备不支持接入网设备所需要的错误源信息，则接入网设备就不会向终端设备发送错误源请求信息，从而节省信令开销，也减少了等待终端设备发送错误源信息所消耗的时间，提升接入网设备获取所需的错误源信息的效率。进一步地，接入网设备可以根据能力信息有针对性地向终端设备发送错误源请求信息，以向终端设备请求终端设备支持的错误源信息。在一些实施例中，错误源请求信息不会用于请求终端设备不支持发送的错误源信息。
综上所述，本公开实施例提供的技术方案中，通过由终端设备向接入网设备发送定位的错误源信息，提供了在上行定位或上行和下行相结合的定位中，实现接入网设备和终端设备之间交互错误源信息的方式；基于错误源信息，可以使接入网设备确定上行定位或上行和下行相结合的定位的定位完整性，从而提供了确定RAT-dependent定位技术的定位完整性的实现方式。
以下通过图5～8这几个的交互实施例，对本公开实施例提供的技术方案进行示例性说明。
针对终端设备主动向接入网设备发送错误源信息的情况：

其中，定位包括上行定位或上行和下行相结合的定位。例如，定位是指基于UL-TDOA或UL-AOA或multi-RTT的定位。其中，基于multi-RTT的定位是上行和下行相结合的定位。错误源信息用于LMF确定该定位的定位完整性。
可选地，终端设备主动向接入网设备发送错误源信息。例如，终端设备可以每隔间隔时间就向接入网设备发送一次错误源信息。又例如，在终端设备中的错误源信息更新(或发生变化)的情况下，终端设备向接入网设备发送更新后的错误源信息。在一些实施例中，向接入网设备发送包含错误源信息的消息，如RRC消息。也即，终端设备向接入网设备发送消息，该消息中包含有错误源信息。
需要理解的是，错误源信息中包含的信息，可以包括允许的误差范围内的误差或错误信息(属于误差范围内、且仍然可用或可信任的误差或错误信息，或这些信息的来源)，也可以包括允许的误差范围之外的误差或错误信息(即误差较大以至于不可用或不可信的信息，或这些信息的来源)。
在一些实施例中，定位完整性包括以下至少之一：

在一些实施例中，由于终端设备只能获取自身运行时生成的相关信息，因而终端设备只能向接入网设备提供与终端设备相关的信息。因为对于与终端设备无关信息，终端设备可能无法获取，也可能仅能获取到过时的或不完整的信息。因此，终端设备向接入网设备发送的错误源信息，包括终端设备的错误信息。在一些实施例中，终端设备的错误信息包括以下至少一种：

在一些实施例中，接入网设备在接收到终端设备发送的错误源信息之后，可以直接将终端设备发送的错误源信息(如终端设备的错误信息)发送给LMF；也可以将与接入网设备相关的错误源信息(如接入网设备的测量错误信息、接入网设备的位置错误信息、多个接入网设备之间的时间同步错误信息、接入网设备的定时错误信息等等)与终端设备发送的错误源信息一起发送给LMF。其中，与接入网设备相关的错误源信息可以是接入网设备自身运行时获取的，也可以是其他接入网设备或非接入网设备发送的，本公开实施例对此不作具体限定。

综上所述，本公开实施例提供的技术方案中，通过终端设备向接入网设备发送能力信息，接入网设备可以根据能力信息确定是否需要向终端设备发送错误源请求信息，或确定向终端设备请求哪些错误源信息，从而节省信令开销，并提升接入网设备获取所需的错误源信息的效率。
针对终端设备向接入网设备发送能力信息、并基于接入网设备的请求发送错误源信息，以及接入网设备基于LMF的请求发送错误源信息的情况：
图9是根据另一示例性实施例示出的一种错误源信息的发送方法的流程图，本实施例以该方法应用于图1所示通信系统中来举例说明。该方法可以包括如下步骤910～950。
在步骤910中，终端设备向接入网设备发送能力信息。
其中，能力信息用于指示终端设备支持发送的定位的错误源信息。例如，在接入网设备向终端设备发送错误源请求信息之前，终端设备主动发送或基于接入网设备的请求发送能力信息，以使得接入网设备了解终端设备支持发送的错误源信息。终端设备也可以向接入网设备指示支持基于某种定位技术的定位完整性能力。例如，基于DL-TDOA、基于DL-AOD、基于multi-RTT、基于UL-TDOA、基于UL-AOA的定位技术。例如，终端设备向接入网设备上报支持基于某种定位技术定位完整性功能，则当使用某种定位技术对终端设备进行定位时可以请求终端设备上报对应该定位技术的错误源信息。
其中，定位包括上行定位或上行和下行相结合的定位。例如，定位是指基于UL-TDOA或UL-AOA或multi-RTT的定位。其中，基于multi-RTT的定位是上行和下行相结合的定位。错误源信息用于LMF确定该定位的定位完整性。在一些实施例中，定位完整性包括以下至少之 一：
·定位系统提供的位置信息的准确性的可信度；
·在定位系统不满足预定操作条件时，发送有效警告的能力。
其中，定位系统是进行上述定位的系统，定位系统可以包括LMF、终端设备和接入网设备中的一种或多种设备。定位完整性用于衡量定位系统提供的位置信息的准确性的可信度，和/或，用于衡量在定位系统不满足预定操作条件时，向LCS客户发送有效警告的能力。在一些实施例中，位置信息是与位置或定位相关的信息或数据。
在一些实施例中，定位完整性用于衡量定位系统提供的位置信息的准确性的可信度，也可以是指用于衡量对定位系统提供的位置信息的准确性的信任。在一些实施例中，不满足预定操作条件包括PL大于AL。其中，PL是根据错误源信息计算得到的，AL是预设的。AL是使定位系统能够用于预定应用的最大允许定位误差。
在一些实施例中，由于终端设备只能获取自身运行时生成的相关信息，因而终端设备只能向接入网设备提供与终端设备相关的信息。因为对于与终端设备无关信息，终端设备可能无法获取，也可能仅能获取到过时的或不完整的信息。因此，能力信息中指示的终端设备支持发送的定位的错误源信息，包括终端设备的错误信息。在一些实施例中，终端设备的错误信息包括以下至少一种：
·终端设备的测量错误；
·终端设备的定时错误；
·终端设备的波束或天线错误。
在一些实施例中，终端设备的测量错误包括终端设备在执行测量时产生的错误，包括终端设备测量定位参考信号时产生的错误。终端设备的定时错误包括与终端设备的定时相关的错误。例如，包括发射信号在终端设备的天线和基带之间的时间差，以及终端设备自身的时钟偏差，例如为终端设备的时钟相对于GNSS时间的差值。终端设备的波束或天线错误包括与终端设备收发的波束或终端设备的天线相关的错误。例如，包括终端设备使用的波束发送方向和实际发送方向之间的偏差。
在一些实施例中，终端设备的测量错误包括以下至少一种：
·终端设备的接收发送时间差；
·RSTD；
·PRS-RSRP；
·PRS-RSRPP。
在步骤920中，接入网设备向终端设备发送错误源请求信息。
其中，错误源请求信息用于请求终端设备发送错误源信息。在一些实施例中，接入网设备在接收到终端设备的能力信息之后，基于能力信息，向终端设备发送与能力信息匹配的错误源请求信息。
在一些实施例中，终端设备仅支持发送与其自身相关的错误源信息，如上述的终端设备的错误信息。终端设备可以不支持发送与终端设备无关的错误源信息，例如，终端设备不支持发送与接入网设备相关的错误源信息(如接入网设备的测量错误信息、接入网设备的位置错误信息、多个接入网设备之间的时间同步错误信息、接入网设备的定时错误信息等等)。接入网设备在获取了终端设备的能力信息之后，可以根据能力信息确定是否向终端设备请求错误源信息。例如，若根据能力信息了解到，终端设备不支持接入网设备所需要的错误源信息，则接入网设备就不会向终端设备发送错误源请求信息，从而节省信令开销，也减少了等待终端设备发送错误源信息所消耗的时间，提升接入网设备获取所需的错误源信息的效率。进一步地，接入网设备可以根据能力信息有针对性地向终端设备发送错误源请求信息，以向终端设备请求终端设备支持的错误源信息。在一些实施例中，错误源请求信息不会用于请求终端设备不支持发送的错误源信息。
在步骤930中，终端设备向接入网设备发送错误源信息。
在一些实施例中，终端设备在接收到接入网设备发送的错误源请求信息之后，基于错误源请求信息向接入网设备发送错误源信息。可选地，若终端设备没有接收到错误源请求信息，就不会向接入网设备发送错误源信息。或者，若终端设备没有接收到错误源请求信息，会按照间隔时间向接入网设备发送错误源信息；若终端设备接收到错误源请求信息，即便距离上次发送错误源信息的时长还不足间隔时间，终端设备也会基于错误源请求信息，提前向接入网设备发送错误源信息。
需要理解的是，错误源信息中包含的信息，可以包括允许的误差范围内的误差或错误信息(属于误差范围内、且仍然可用或可信任的误差或错误信息，或这些信息的来源)，也可以包括允许的误差范围之外的误差或错误信息(即误差较大以至于不可用或不可信的信息，或这些信息的来源)。
在步骤940中，LMF向接入网设备发送请求信息。
其中，请求信息用于请求接入网设备发送错误源信息。
在步骤950中，接入网设备向LMF发送错误源信息。
在一些实施例中，接入网设备在接收到LMF发送的请求信息之后，响应于该请求信息，向LMF发送其所请求的错误源信息。也即，接入网设备发送的错误源信息，是基于LMF的请求发送的。
综上所述，本公开实施例提供的技术方案中，通过终端设备向接入网设备发送能力信息，接入网设备可以根据能力信息确定是否需要向终端设备发送错误源请求信息，或确定向终端设备请求哪些错误源信息，从而节省信令开销，并提升接入网设备获取所需的错误源信息的效率。
另外，接入网设备在接收到错误源请求信息之后，才会向LMF发送错误源信息；在没有接收到错误源请求信息的情况下就可以不发送错误源信息，从而节省接入网设备的信令开销。
需要说明的是，上述有关终端设备执行的步骤，可以单独实现成为终端设备侧的错误源信息的发送方法；上述有关接入网设备执行的步骤，可以单独实现成为接入网设备侧的错误源信息的发送方法；上述有关LMF执行的步骤，可以单独实现成为LMF侧的错误源信息的接收方法。
