背景技术
5G(5th Generation Mobile Communication Technology,第五代移动通信技术)标准R18(Release 18,第18版)正在研究如何支持蜂窝网定位的完好性,包括UE-based integrity(基于UE(User Equipment,用户设备)的完好性)和LMF-based integrity(基于LMF(L ocation Management Function,位置管理功能)的完好性)两种模式。
针对UE-based integrity模式,当LMF向UE请求获取定位完好性时,UE会根据LMF提供的完好性辅助数据进行定位完好性的计算,并将定位完好性计算结果提供给LMF(如果UE能计算出来)。但是针对UE无法提供定位完好性计算结果的情况,当前没有讨论过对应的处理机制。

下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
5G标准R18正在研究如何支持蜂窝网定位的完好性,包括UE-based integrity和LMF-based integrity两种模式。
针对UE-based integrity模式,当LMF向UE请求获取定位完好性时,UE会基于LMF提供的定位完好性辅助数据(error sources(误差源),包括TRP(Transmission and Reception Point,发射接收点)位置误差、TRP同步误差等)来进行定位完好性的计算,并将定位完好性计算结果上报给LMF。
针对LMF-based integrity模式,LMF可以直接基于UE和/或服务基站提供的定位完好性辅助数据(主要包括测量和基站位置等相关的error sources)来进行定位完好性的计算。
然而针对UE-based integrity模式,当UE无法向LMF提供定位完好性计算结果时,当前没有讨论过对应的处理机制,从而存在LMF持续使用错误的定位方法或者定位完好性辅助数据而导致多次定位完好性失败的情况,大大降低定位系统的效率和计算完好性成功率。
针对上述问题,本公开实施例提供了定位信息处理方法及装置,可实现在采用UE-based  integrity模式支持蜂窝网定位的完好性时,针对终端设备无法提供定位完好性计算结果的情况,向定位服务器指示完好性失败原因,避免定位服务器持续使用错误的定位方法或者定位完好性辅助数据而导致多次定位完好性失败,有效提高定位系统的效率和计算定位完好性成功率。
其中,方法和装置是基于同一发明构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。

在具体描述本公开实施例之前,为了便于理解,首先对相关技术背景进行介绍:
一、NG-RAN(Next Generation Radio Access Network,下一代无线接入网)定位架构
图1是根据本公开第一实施例所提供的相关技术中NG-RAN定位架构的示意图,图1中,UE表示用户设备,SET(SUPL Enabled Terminal,SUPL使能终端)表示SUPL(Secure User Plane Location,安全用户平面定位)协议使能终端,LTE-Uu(U表示用户网络接口(User to Network interface),u表示通用(Universal))表示LTE终端和基站间的空中接口,NR-Uu表示NR终端和基站间的空中接口,TP(Transmission Point,传输点)表示传输点,TRP表示收发节点,ng-eNB(next generation Evolved Node B,ng-eNode B)、gNB((next)Generation Node B,gNodeB)都表示5G基站,NG-C表示NG控制面接口,LMF表示定位管理功能,AMF(Access and Mobility Management Function,访问和移动管理功能)表示认证管理功能,E-SMLC(Enhanced Serving Mobile Location Center,增强服务移动定位中心)表示服务移动位置中心,SLP(SUPL Location Platform)表示SUPL定位平台。
如图1所示,LMF为定位服务器,负责选择定位方法及触发相应的定位测量,并可以 计算定位最终结果和精度。在一些实施例中,LMF可以与多个NG-RAN节点进行交互,以提供用于广播的辅助数据信息,也可以对用于广播的辅助数据信息进行分段和/或加密,还可以与AMF进行交互,以向AMF提供加密密钥数据信息。
UE为用户设备,可以发送定位参考信号,或者基于辅助信息进行定位测量,或者基于测量结果计算定位最终结果和精度。
ng-eNB、gNB均为5G基站,可以在定位系统信息消息中广播从LMF接收的辅助数据信息。
二、UE-based下行定位方法
UE-based下行定位方法,比如DL-AoD(Downlink angle-of-departure,下行偏离角)和DL-TDOA(Downlink time difference of arrival,下行到达时差)等,是由基站发送下行定位参考信号(positioning reference signal,PRS),UE接收该参考信号并进行测量,根据定位方法的不同,UE进行的测量量也不同。之后UE根据测量量,和LMF提供的辅助数据,来计算位置信息,并将最终计算出来的位置结果上报给LMF。
三、信令交互过程
UE与LMF之间通过LPP(LTE Positioning Protocol,LTE定位协议)信令交互,基站与定位服务器之间通过NRPPa(NR positioning protocol A,NR定位协议A)信令交互。
四、定位完好性及其计算
针对UE-based integrity模式,当LMF向UE请求获取定位完好性时,UE会基于LMF提供的定位完好性辅助数据(error sources,包括TRP位置误差、TRP同步误差等)来进行定位完好性的计算,并将定位完好性计算结果上报给LMF。
针对LMF-based integrity模式,LMF可以直接基于UE和/或服务基站提供的定位完好性辅助数据(主要包括测量和基站位置等相关的error sources)来进行定位完好性的计算。
定位完好性:定位完好性是对系统提供的位置相关数据的准确性的信任度,以及在定位系统不满足预期操作条件时能够向客户提供及时有效警告的能力的一种测量。
P(误差>边界|NOT DNU)<=Residual Risk+IRallocation
误差:误差是参数的真实值与其在相应辅助数据中估计和提供的值之间的差异。
边界:边界提供与定位校正相关的残差的统计分布,用于在应用定位校正后统计地限制残差。
边界公式描述了一个边界模型,包括平均值和标准偏差。在一些实施例中,可以根据以下公式计算特定误差的界限:
Bound=mean+K*stdDev
K=normInv(IRallocation/2)
irMinimum<=IRallocation<=irMaximum
其中,Bound表示特定误差的上限值,mean表示平均值,stdDev表示标准偏差,normInv表示正态分布的反函数,irMinimum表示服务器设定的IRallocation的最小值;irMaximum表示服务器设定的IRallocation的最大值。
DNU(Do Not Use):特定错误相对应的DNU标志,用来指示相关错误来源的辅助数据可否用于定位完好性计算。该参数设置为否的时候,表明相关辅助数据可用于定位完好性计算;反之,则表明这些辅助数据不可用于完好性计算。
Residual Risk:残余风险是每单位时间定义的故障事件发生的概率。每个残余风险都伴随着一个平均持续时间,它代表相应故障事件的预期平均持续时间,用于将发生概率转换为在任何给定时间存在故障事件的概率。
P(故障事件发生)=平均持续时间*单位时间定义的故障事件发生的概率
IRallocation:IRallocation表示单次定位完好性的值。
五、RTD(Relative Time Difference,相对时差)信息(TRP间的时间同步信息)
RTD信息提供了参考TRP和一系列相邻TRP之间的时间同步信息及其不确定度。
六、TRP/ARP位置信息
TRP位置信息指的是基站下的某个TRP相对某个参考点的位置及其不确定度;ARP(Antenna Reference Point,天线参考点)位置信息指的是某个TRP下的某个PRS(Positioning Reference Signal,定位参考信号)资源发送接收点的位置及其不确定度。
下面参考附图描述本公开实施例的定位信息处理方法及装置。
图2是根据本公开第二实施例所提供的定位信息处理方法的流程示意图。
需要说明的是,本公开实施例的定位信息处理方法可以由本公开实施例提供的定位信息处理装置执行。该定位信息处理装置可以为电子设备,也可以被配置在电子设备中。其中,电子设备,可以是任意能够进行数据处理的静止或者移动计算设备,例如笔记本电脑、智能手机、可穿戴设备等移动计算设备,或者台式计算机等静止的计算设备,或者服务器,或者其它类型的计算设备等,本实施例中对此不作限制。
如图2所示,该定位信息处理方法可以包括以下步骤201至202。
步骤201,接收定位服务器发送的请求信息,其中,请求信息用于请求获取定位完好性计算结果。
需要说明的是,本实施例提供的定位信息处理方法应用于终端设备,比如UE。
在本实施例中,定位服务器可以是LMF,也可以是其他提供定位服务的服务器,本实施例中对此不做限制。
在本实施例中,定位服务器发送的请求信息是用于向终端设备请求获取定位完好性计 算结果的。可以理解的是,由于UE与LMF之间通过LPP信令交互,在一些实施例中,请求信息可以是LPP信令。
在本实施例中,终端设备可以接收定位服务器发送的用于向该终端设备请求获取定位完好性计算结果的请求信息,从而响应于该请求信息,基于其是否能提供定位完好性计算结果,向定位服务器发送对应的响应信息。
步骤202,在终端设备无法提供定位完好性计算结果的情况下,向定位服务器发送用于指示完好性失败原因的响应信息。
在本实施例中,终端设备无法提供定位完好性计算结果的情况可以包括终端设备无法计算定位完好性、终端设备计算定位完好性失败等。
在本实施例中,完好性失败原因包括下列中的至少一种:
终端设备不支持定位完好性计算;
终端设备不支持定位服务器选定的定位方法;
终端设备不支持在定位服务器选定的定位方法下进行定位完好性计算;
定位服务器提供的定位完好性辅助数据不可用;
定位服务器提供的定位完好性辅助数据不足;
定位完好性计算失败。
在一些实施例中,integrity error cause(完好性失败原因)的编码可以如下所示:
需要说明的是,由于针对UE-based integrity模式,UE是基于LMF提供的定位完好性辅助数据来进行定位完好性的计算的,因此,在一些实施例中,定位服务器可以在发送用于向终端设备请求获取定位完好性计算结果的请求信息之前,向终端设备发送其所选定的定位方法和/或定位完好性辅助数据,以便于终端设备进行定位完好性的计算。
在本实施例中,响应信息可以为LPP信令。在一些实施例中,响应信息所指示的完好性失败原因可以携带于LPP common IE中,或者,也可以与定位方法相对应,本实施例中对此不做限制。
在一些实施例中,若响应信息所指示的完好性失败原因携带于LPP common IE中,即integrity error cause(完好性失败原因)可以通过过程指示(携带在common IE中),则integrity error cause(完好性失败原因)可以携带在LPP common IE中的CommonIEsProvideLocationInformation,具体编码如下所示:
上述编码中“[[
integrityErrorCause-r18IntegrityErrorCause-r18 OPTIONAL,
]]”用于指示integrity error cause(完好性失败原因)。
若响应信息所指示的完好性失败原因与定位方法相对应,即integrity error cause(完好性失败原因)可以通过定位方法指示,即针对各定位方法,在各定位方法中单独指示其完好性失败原因,从而针对DL-AoD单独指示其integrity error cause(完好性失败原因)的编码可以如下所示:

上述编码中“[[
nr-DL-AoD-integrityErrorCause-r18        IntegrityErrorCause-r18OPTIONAL,
]]”即为DL-AoD的integrity error cause(完好性失败原因)。
针对DL-TDOA单独指示其integrity error cause(完好性失败原因)的编码可以如下所示:

上述编码中“[[
nr-DL-TDOA-integrityErrorCause-r18      IntegrityErrorCause-r18OPTIONAL,
]]”即为DL-TAoD的integrity error cause(完好性失败原因)。
在本实施例中,终端设备可以在其无法提供定位完好性计算结果的情况下,向定位服务器发送用于指示完好性失败原因的响应信息。相对应地,若终端设备能够确定定位完好性计算结果,则终端设备可以向定位服务器发送携带有定位完好性计算结果的响应信息。也就是说,当且仅当定位完好性计算结果不包含在响应消息中时,终端设备需要指示对应的完好性失败原因。
本公开实施例提供的定位信息处理方法,终端设备在无法提供定位完好性计算结果的情况下,向定位服务器发送用于指示完好性失败原因的响应信息。由此,可实现在采用UE-based integrity模式支持蜂窝网定位的完好性时,针对终端设备无法提供定位完好性计算结果的情况,向定位服务器指示完好性失败原因,避免定位服务器持续使用错误的定位方法或者定位完好性辅助数据而导致多次定位完好性失败,有效提高定位系统的效率和计算定位完好性成功率。
上一实施例从终端设备组件角度描述了定位信息处理方法的实现过程,下面结合图3,从定位服务器角度描述一种定位信息处理方法可能的实现方式,图3是根据本公开第三实施例所提供的定位信息处理方法的流程示意图。
如图3所示,该定位信息处理方法可以包括以下步骤301至302。
步骤301,向终端设备发送请求信息,其中,请求信息用于请求获取定位完好性计算结果。
需要说明的是,本实施例提供的定位信息处理方法应用于定位服务器。其中,定位服务器可以是LMF,也可以是其他提供定位服务的服务器,本实施例中对此不做限制。
在本实施例中,定位服务器可以向终端设备发送用于请求获取定位完好性计算结果的请求信息。在一些实施例中,当定位服务器为LMF时,由于UE与LMF之间通过LPP信令交互,在一些实施例中,定位服务器发送的请求信息可以是LPP信令。
步骤302,接收终端设备发送的响应信息,其中,响应信息用于指示完好性失败原因。
在本实施例中,响应信息是终端设备在无法提供定位完好性计算结果的情况下发送的,用于指示完好性失败原因的响应信息。
在本实施例中,响应信息可以为LPP信令。在一些实施例中,响应信息所指示的完好性失败原因可以携带于LPP common IE中,或者,也可以与定位方法相对应,本实施例中对此不做限制。
在一些实施例中,若响应信息所指示的完好性失败原因携带于LPP common IE中,即integrity error cause(完好性失败原因)可以通过过程指示(携带在common IE中),则integrity error cause(完好性失败原因)可以携带在LPP common IE中的CommonIEsProvideLocationInformation,具体编码如下所示:
上述编码中“[[
integrityErrorCause-r18 IntegrityErrorCause-r18    OPTIONAL,
]]”用于指示integrity error cause(完好性失败原因)。
若响应信息所指示的完好性失败原因与定位方法相对应,即integrity error cause(完好性失败原因)可以通过定位方法指示,即针对各定位方法,在各定位方法中单独指示其完好性失败原因,从而针对DL-AoD单独指示其integrity error cause(完好性失败原因)的编码可以如下所示:

上述编码中“[[
nr-DL-AoD-integrityErrorCause-r18      IntegrityErrorCause-r18 OPTIONAL,
]]”即为DL-AoD的integrity error cause(完好性失败原因)。
针对DL-TDOA单独指示其integrity error cause(完好性失败原因)的编码可以如下所示:

上述编码中“,
[[
nr-DL-TDOA-integrityErrorCause-r18      IntegrityErrorCause-r18 OPTIONAL,
]]”即为DL-TAoD的integrity error cause(完好性失败原因)。
在本实施例中,终端设备无法提供定位完好性计算结果的情况可以包括终端设备无法计算定位完好性、终端设备计算定位完好性失败等。
在本实施例中,完好性失败原因包括下列中的至少一种:
终端设备不支持定位完好性计算;
终端设备不支持定位服务器选定的定位方法;
终端设备不支持在定位服务器选定的定位方法下进行定位完好性计算;
定位服务器提供的定位完好性辅助数据不可用;
定位服务器提供的定位完好性辅助数据不足;
定位完好性计算失败。
在一些实施例中,integrity error cause(完好性失败原因)的编码可以如下所示:
需要说明的是,由于针对UE-based integrity模式,UE是基于LMF提供的定位完好性辅助数据来进行定位完好性的计算的,因此,在一些实施例中,定位服务器可以在向终端设备发送用于请求获取定位完好性计算结果的请求信息之前,向终端设备发送其所选定的 定位方法和/或定位完好性辅助数据,以便于终端设备进行定位完好性的计算。
在本实施例中,定位服务器在向终端设备发送用于请求获取定位完好性计算结果的请求信息之后,可以接收终端设备在无法提供定位完好性计算结果的情况下发送的,用于指示完好性失败原因的响应信息。
本公开实施例提供的定位信息处理方法,通过向终端设备发送请求信息,其中,请求信息用于请求获取定位完好性计算结果,实现接收终端设备发送的响应信息,其中,响应信息是终端设备在无法提供定位完好性计算结果的情况下发送的,用于指示完好性失败原因的响应信息。由此,可实现在采用UE-based integrity模式支持蜂窝网定位的完好性时,针对终端设备无法提供定位完好性计算结果的情况,定位服务器能够及时获取完好性失败原因,以避免持续使用错误的定位方法或者定位完好性辅助数据而导致多次定位完好性失败的情况发生,有效提高定位系统的效率和计算定位完好性成功率。
需要说明的是,本公开实施例中,定位服务器在接收到终端设备在无法提供定位完好性计算结果的情况下发送的,用于指示完好性失败原因的响应信息之后,还可以基于定位完好性失败原因执行相应的处理,下面结合图4,对这一过程进行说明。图4是根据本公开第四实施例所提供的定位信息处理方法的流程示意图。
如图4所示,该定位信息处理方法可以包括以下步骤401至403。
步骤401,向终端设备发送请求信息,其中,请求信息用于请求获取定位完好性计算结果。
步骤402,接收终端设备发送的响应信息,其中,响应信息用于指示完好性失败原因。
需要说明的是,步骤401-402的执行过程可以参加上一实施例中步骤301-302的执行过程,原理相同,在此不再赘述。
步骤403,根据完好性失败原因,重新进行定位。
在本实施例中,定位服务器可以根据接收到的完好性失败原因,重新进行定位。在一些实施例中,定位服务器根据接收到的完好性失败原因,重新进行定位可以包括一项或多项:
更改定位方法;
重新提供定位完好性辅助数据;
更改定位模式。
在一些实施例中,定位服务器可以根据接收到的完好性失败原因,更改定位方法,和/或,根据接收到的完好性失败原因,重新提供定位完好性辅助数据,和/或,根据接收到的完好性失败原因,更改定位模式。具体地,定位服务器可以在完好性失败原因为终端设备 不支持定位服务器选定的定位方法,或者终端设备不支持在定位服务器选定的定位方法下进行定位完好性计算的情况下,更改定位方法,和/或,在完好性失败原因为定位服务器提供的定位完好性辅助数据不可用,或者定位服务器提供的定位完好性辅助数据不足的情况下,重新提供定位完好性辅助数据,和/或,在完好性失败原因为终端设备不支持定位完好性计算,或者定位完好性计算失败的情况下,更改定位模式。

]]”即为DL-TAoD的integrity error cause(完好性失败原因)。
需要说明的是,在本实施例中,当且仅当定位完好性计算结果不包含在响应消息中时,终端设备需要指示对应的integrity error cause(完好性失败原因)。并且,integrity error cause(完好性失败原因)可以通过过程指示(携带在common IE中),或者可以通过定位方法指示。
在一些实施例中,定位服务器在接收到终端设备在无法提供定位完好性计算结果的情况下发送的,用于指示完好性失败原因的响应信息之后,还可以根据接收到的完好性失败原因,重新进行定位。在一些实施例中,定位服务器可以在完好性失败原因为终端设备不支持定位服务器选定的定位方法,或者终端设备不支持在定位服务器选定的定位方法下进行定位完好性计算的情况下,更改定位方法,和/或,在完好性失败原因为定位服务器提供 的定位完好性辅助数据不可用,或者定位服务器提供的定位完好性辅助数据不足的情况下,其中定位完好性数据不足指的是提供的定位完好性数据数据无法进行或者完成定位完好性计算结果的计算,或者是无法进行或者准确完成定位完好性计算结果的计算,则需要重新提供定位完好性辅助数据,和/或,在完好性失败原因为终端设备不支持定位完好性计算,或者定位完好性计算失败的情况下,更改定位模式。
在一些实施例中,若integrity error cause(完好性失败原因)中指示不支持LMF选定的定位方法的定位完好性计算,则LMF可以在下次定位时,选择其它定位方法;若integrity error cause(完好性失败原因)中指示定位完好性辅助数据不足够,则LMF可以在下次定位时,提供更多的定位完好性辅助数据;若integrity error cause(完好性失败原因)中指示不支持定位完好性计算或定位完好性计算失败,则LMF可以在下次定位时,不触发定位完好性计算,或LMF选择LMF-based integrity模式来计算定位完好性。
综上,针对相关技术中,在UE-based integrity模式下,当UE无法计算定位完好性,或计算定位完好性失败时,如果没有指示失败原因,可能会导致LMF持续选择错误的定位方法或者辅助数据,导致多次定位完好性失败,大大降低定位系统的效率和计算完好性成功率的问题,终端设备通过在接收到定位服务器发送的用于请求获取定位完好性的请求信息之后,响应于无法提供定位完好性计算结果,在响应消息中指示相对应的integrity error cause(完好性失败原因),以使LMF确定定位完好性失败的原因,并在后续定位过程中选择合适的定位方法或定位完好性辅助数据,从而有效提高定位系统的效率和计算定位完好性成功率。
