Description

终端设备的定位方法、装置及存储介质
本申请要求于2021年04月27日提交中国专利局、申请号为202110460714.0、申请名称为“终端设备的定位方法、装置及存储介质”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,尤其涉及一种终端设备的定位方法、装置及存储介质。
背景技术
位置服务(Location Based Services,LBS)技术是一种通过无线通信网络或其他定位系统获取终端位置信息,再结合地理信息系统为终端提供与位置相关的各类信息的服务技术。
在第五代移动通信技术(5th-Generation,5G)定位网络架构中,定位管理功能实体(Location Management Function,LMF)将确定终端设备进行定位的定位方法。另外,服务基站以及非服务基站将确定与上述定位方法所对应的定位辅助数据,并将该定位辅助信息发送给LMF,以使LMF确定终端设备的位置信息。其中,定位辅助数据包括定位参考信号(Positioning Reference Signal,PRS)/探测参考信号(Sounding Reference Signal,SRS)的时频资源配置、周期、噪声抑制(Muting)机制等。
然而,上述的定位方法,会造成系统资源的开销较大,导致资源的浪费。
发明内容
本申请提供一种终端设备的定位方法、装置及存储介质,可以保证该终端设备的定位精度和定位时延,而且可以降低系统资源的开销,减少资源的浪费。
一方面,本申请提供一种终端设备的定位方法,应用于第一网元,包括:
从终端设备接收第一消息,所述第一消息中包括定位服务质量QoS信息;
向第一网络设备发送第二消息,所述第二消息中包括所述定位QoS信息或与所述定位QoS信息对应的初始定位辅助数据;
接收所述第一网络设备发送的第一目标定位辅助数据,并向第二网络设备发送所述第一目标定位辅助数据,所述第一目标定位辅助数据与所述定位QoS信息相关;
接收来自所述第一网络设备的第一定位测量值以及来自所述第二网络设备的第二定位测量值,所述第一定位测量值为所述第一网络设备根据所述第一目标定位辅助数据接收上行定位参考信号后,对所述上行定位参考信号进行测量后得到的,所述第二定位测量值为所述第二网络设备根据所述第一目标定位辅助数据接收所述上行定位参考信号后,对所述上行定位参考信号进行测量后得到的;
根据所述第一定位测量值和所述第二定位测量值,确定所述终端设备的位置信息。
在本方案中,由于第一网络设备在为终端设备分配第一目标定位辅助数据时,可以考虑每个终端设备的定位QoS信息,针对每个终端设备的定位QoS信息,分别为每个终端设备分配对应的第一目标定位辅助数据,而不再是针对所有的终端设备统一分配定位辅助数据,这样,由于考虑了每个终端设备的定位QoS信息为该终端设备分配定位辅助数据,从而不仅可以保证该终端设备的定位精度和定位时延,而且可以降低系统资源的开销,减少资源的浪费。
在一种可能的实现方式中,所述第二消息中包括与所述定位QoS信息对应的初始定位辅助数据;
所述向第一网络设备发送第二消息之前,还包括:
根据预先存储的定位QoS信息、定位参考信号的配置参数和所述配置参数对应的门限值之间的对应关系,确定与所述定位QoS信息对应的配置参数的取值;
将所述配置参数的取值确定为所述初始定位辅助数据。
在本方案中,第一网元可以根据预先存储的定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,确定与定位QoS信息对应的配置参数的取值,并将该取值确定为初始定位辅助数据,由此可以将定位辅助数据和终端设备的定位QoS信息进行关联,避免了现有技术中针对所有的终端设备统一分配定位辅助数据的现象,而是考虑了每个终端设备的定位QoS信息,为该终端设备分配对应的定位辅助数据,从而不仅可以保证该终端设备的定位精度和定位时延,而且可以降低系统资源的开销,减少资源的浪费。
在一种可能的实现方式中,所述第一消息中还包括终端设备的能力信息;
所述方法还包括:
根据所述终端设备的能力信息,更新所述配置参数对应的门限值。
在本方案中,由于第一网元可以根据终端设备的能力信息,对配置参数对应的门限值进行更新,由此可以避免所有的终端设备均采用同一个门限值的现象,不仅提高了配置参数门限值选择的灵活性,而且针对每个终端设备,可以确定不同的门限值,提高了定位辅助数据的准确性。
在一种可能的实现方式中,所述第二消息中还包括定位QoS信息、定位参考信号的配置参数和所述配置参数对应的门限值之间的对应关系。
在本方案中,由于第一网元可以预先将定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系发送给第一网络设备,这样,在第一网络设备本地将存储有该对应关系,第一网络设备在接收到第一网元发送的定位QoS信息后,可以直接根据该对应关系,确定初始定位辅助数据,而不需要在每次确定初始定位辅助数据时,均需要第一网元向第一网络设备发送该对应关系,从而可以提高确定初始定位辅助数据的效率。
在一种可能的实现方式中,所述第二消息中还包括更新后的所述配置参数对应的门限值。
在本方案中,第一网元在根据终端设备的能力信息对配置参数对应的门限值进行更新后,将该更新后的门限值发送给第一网络设备,不仅提高了配置参数门限值选择的灵活性,而且针对每个终端设备,可以确定不同的门限值,提高了所确定的定位辅 助数据的准确性。

根据预先存储的定位QoS信息、定位参考信号的配置参数和所述配置参数对应的门限值之间的对应关系,确定与所述目标定位QoS信息对应的配置参数的取值。
在本方案中,第一网元可以根据至少两个终端设备各自对应的优先级,确定最终的目标定位QoS信息,从而确定出相应的初始定位辅助数据,由此可以提高初始定位辅助数据的准确性。

接收所述终端设备发送的第一定位测量值和第二定位测量值,所述第一定位测量值为所述终端设备根据所述第一目标定位辅助数据接收所述第一网络设备发送的第一下行定位参考信号,并对所述第一下行定位参考信号进行测量得到的,所述第二定位测量值为所述终端设备根据所述第二目标定位辅助数据接收所述第二网络设备发送的第二下行定位参考信号,并对所述第二下行定位参考信号进行测量得到的;

本申请提供一种终端设备的定位方法、装置及存储介质,第一网元从终端设备接收到的第一消息中包括有定位QoS信息,第一网元可以根据该定位QoS信息确定初始定位辅助数据,并将该初始定位辅助数据发送给第一网络设备,或者第一网元可以直接将定位QoS信息发送给第一网络设备,以使第一网络设备根据初始定位辅助数据或定位QoS信息确定第一目标定位辅助数据,从而使得第一网元可以获取到与该第一目标定位辅助数据对应的定位测量值,以确定终端设备的位置信息。由于第一网络设备在为终端设备分配第一目标定位辅助数据时,可以考虑每个终端设备的定位QoS信息,针对每个终端设备的定位QoS信息,分别为每个终端设备分配对应的第一目标定位辅助数据,而不再是针对所有的终端设备统一分配定位辅助数据,这样,由于考虑了每个终端设备的定位QoS信息为该终端设备分配定位辅助数据,从而不仅可以保证该终 端设备的定位精度和定位时延,而且可以降低系统资源的开销,减少资源的浪费。

本申请实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
下面将结合本申请实施例中的附图,对本申请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申请一部分实施例,并不是全部的实施例。基于本申请中的实施例,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,都属于本申请保护的范围。
本申请实施例提供的终端设备的定位方法、装置及存储介质,用于任何需要确定终端设备的位置的应用场景中,例如导航、测距、基于紧急呼叫定位主叫用户或者基于用户请求,定位已授权的其他用户等等。
本申请实施例提供的技术方案可以适用于多种系统,尤其是5G系统。例如适用 的系统可以是全球移动通讯(global system of mobile communication,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)通用分组无线业务(general packet radio service,GPRS)系统、长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、高级长期演进(long term evolution advanced,LTE-A)系统、通用移动系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)系统、5G新空口(New Radio,NR)系统等。这多种系统中均包括终端设备和网络设备。系统中还可以包括核心网部分,例如演进的分组系统(Evloved Packet System,EPS)、5G系统(5GS)等。
图1为本申请实施例适用的5G通信系统结构示意图,如图1所示,5G通信系统由5G核心网(5G Core,5GC)网元101和无线接入网(Next Generation Radio AccessNetwork,NG-RAN)网元102组成,5GC网元101与NG-RAN网元102通过NG口连接。
其中,组成5GC 101的网元包括用于支持访问和移动管理等控制平面功能的接入移动管理功能(Access and Mobility Management Function,AMF)、用于提供定位服务的核心网定位管理功能(Core Network Location Management Function,CN LMF)和用于支持用户平面功能的用户平面功能(User Plane Function,UPF)等(图中未示出)。
组成NG-RAN的网元包括RAN节点(如图中所示的102a~102d)。RAN节点包括网络设备,例如为5G网络提供无线网络用户平面和控制平面协议和功能的gNB或者为4G网络用户提供无线网络的用户平面和控制平面协议和功能的ng-eNB。在接入网络侧,gNB与ng-eNB、gNB与gNB以及gNB与gNB之间通过Xn口连接,即接入网中的RAN节点之间通过Xn口连接。需要说明的是,在以下描述中,将AMF实体简称为AMF,将LMF实体简称为LMF。
其中,RAN节点包括终端设备的服务基站以及终端设备的邻站,例如,若终端设备处于gNB 102a所覆盖的小区内,则gNB 102a为终端设备的服务基站,gNB 102b为终端设备的邻站。
需要说明的是,以上架构是以5G系统架构为例描述的。本申请实施例也可适用于5G演进系统,或适用于其他通信系统(比如4G通信系统),或者适用于5G系统和其它通信系统(比如4G系统)混合组网的系统架构等,在此不再一一列举。举例来说,在4G通信系统或4G通信系统与5G通信系统混合组网的系统中,可由移动管理实体(Mobility Management Entity,MME)实现移动管理。
基于上述系统结构,核心网中的CN LMF在AMF或MME等核心网元的协作下,通过RAN节点为终端设备提供定位服务。
图2为本申请实施例适用的5G网络中的定位服务网络结构示意图,该图中示例性地列举了与本申请实施例相关的部分网元。如图2所示,LMF包括核心网LMF(如图中的LMF 203),还包括设置于接入网侧的本地LMF(Local LMF,LLMF)。本地LMF与RAN节点之间存在关联,比如一个本地LMF可以对应于一个或多个RAN节点。本地LMF可以与RAN节点共址设置,这样该本地LMF与其所共址的RAN节点 关联(如图中的本地LMF(Local LMF,LLMF)206与RAN节点204共址设置)。
基于上述系统架构,终端设备的定位服务过程可包括:LCS实体201向AMF 202发起定位服务请求;AMF 202根据网络配置以及终端设备205相关信息选择为终端设备205提供定位服务的LMF。若AMF 202选择LMF 203为终端设备205提供定位服务,则向LMF 203发起定位服务请求,若AMF选择与终端设备205驻留的RAN节点(即服务RAN节点)204所共址的LLMF 206为终端设备205提供定位服务,则向RAN节点204共址的LLMF 206发起定位服务请求;LMF 203或者LLMF 206通过与AMF202、RAN节点204以及终端设备205交互获得终端设备205的位置信息,并通过AMF202向LCS实体201发送定位服务响应消息。由此可以完成对终端设备位置信息的确定。
本申请实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中,终端设备的名称可能也不相同,例如在5G系统中,终端设备可以称为用户设备(User Equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本申请实施例中并不限定。
本申请实施例涉及的网络设备,可以是基站,该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同,基站又可以称为接入点,或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备,或者其它名称。网络设备可用于将收到的空中帧与网际协议(Internet Protocol,IP)分组进行相互更换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如,本申请实施例涉及的网络设备可以是全球移动通信系统(Global System for Mobile communications,GSM)或码分多址接入(Code Division Multiple Access,CDMA)中的网络设备(Base Transceiver Station,BTS),也可以是带宽码分多址接入(Wide-band Code Division Multiple Access,WCDMA)中的网络设备(NodeB),还可以是长期演进(long term evolution,LTE)系统中的演进型网络设备(evolutional Node B,eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB),也可以是家庭演进基站(Home evolved Node B,HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等,本申请实施例中并不限定。在一些网络结构中, 网络设备可以包括集中单元(centralized unit,CU)节点和分布单元(distributed unit,DU)节点,集中单元和分布单元也可以地理上分开布置。
网络设备与终端设备之间可以各自使用一或多根天线进行多输入多输出(Multi Input Multi Output,MIMO)传输,MIMO传输可以是单用户MIMO(Single User MIMO,SU-MIMO)或多用户MIMO(Multiple User MIMO,MU-MIMO)。根据根天线组合的形态和数量,MIMO传输可以是2D-MIMO、3D-MIMO、FD-MIMO或massive-MIMO,也可以是分集传输或预编码传输或波束赋形传输等。
本申请实施例涉及的LMF,可以用于实现终端设备的位置估计。LMF可以部署于核心网内部,即LMF也属于一种核心网网元。LMF可以通过AMF与接入网设备,如接入节点NG RAN进行通信。为了便于描述,本申请实施例中将LMF通过AMF向接入网设备发送信息简称为LMF向接入网设备发送信息。换句话说,本申请实施例中所称的LMF向接入网设备发送消息可以理解为该LMF先将信息发送至AMF,该AMF再将该信息转发至该接入网设备。
另外,LMF还可以与终端设备通信。例如,LMF可以通过LTE定位协议(LTE positioning protocol,LPP)与终端设备进行通信。
目前,在5G新空口(new radio,NR)协议中,在确定终端设备的位置信息时,通常由LMF确定终端设备定位时所采用的定位方法,但是该定位方法所涉及到的定位参考信号、定位辅助数据和测量上报机制是由服务基站为终端设备分配的。服务基站在为终端设备分配定位参考信号和对应的定位辅助数据时,为了保证所有终端设备的定位精度和时延,将会根据通信性能最差的终端设备的相关参数,为所有终端设备分配定位辅助数据,例如分配定位参考信号(positioning reference signal,PRS)资源/探测参考信号(sounding reference signal,SRS)资源,这样会增加系统资源的开销,造成资源的浪费。
考虑到上述问题,本申请实施例中提出一种终端设备的定位方法,在该方法中,可以通过协议预定义或者预配置的方式,预先建立定位服务质量(Quality of Service,QoS)信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,第一网元或服务基站将根据该对应关系确定与定位QoS信息对应的初始定位辅助数据,从而使得服务基站和/或相邻基站在为终端设备分配目标定位辅助数据时,可以考虑每个终端设备的定位QoS信息,针对每个终端设备的定位QoS信息,分别为每个终端设备分配对应的目标定位辅助数据,而不再是针对所有的终端设备统一分配定位辅助数据,这样,由于考虑了每个终端设备的定位QoS信息为该终端设备分配定位辅助数据,从而不仅可以保证该终端设备的定位精度和定位时延,而且可以降低系统资源的开销,减少资源的浪费。
其中,方法和装置是基于同一申请构思的,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。
下面,将针对上行定位方法、下行定位方法和上行+下行定位方法分别说明本申请的技术方案。
图3为本申请一实施例提供的终端设备的定位方法的信令流程图,本实施例中对LMF采用上行定位方法确定终端设备的位置信息的方案进行详细说明。如图3所示, 该方法包括:
步骤301:第一网元从终端设备接收第一消息,该第一消息中包括定位QoS信息。
在本步骤中,第一网元为图2中的LMF,可以为LMF 203,也可以为LLMF 206。终端设备向第一网元发送的第一消息中,携带有定位QoS信息。其中,该定位QoS信息包括如下信息中的至少一个:定位精度、定位时延、终端设备的应用场景,如应用于高速场景或者低速场景或终端设备的优先级等等。
步骤302:第一网元向第一网络设备发送第二消息,该第二消息中包括定位QoS信息或与定位QoS信息对应的初始定位辅助数据。
其中,第一网络设备包括终端设备的服务基站。示例性的,当参与发送或接收按需分配(On demand)PRS/SRS的传输接收点(Transmission Reception Point,TRP)都属于同一个服务基站时,由服务基站确定按需分配(On demand)PRS/SRS的时频资源配置参数,也即确定目标定位辅助数据。当参与发送或接收On demand PRS/SRS的TRP属于服务基站以及相邻基站时,由服务基站和相邻基站分别确定各自的按需分配(On demand)PRS/SRS的时频资源配置参数,也即服务基站和相邻基站分别确定各自对应的目标定位辅助数据。本申请中均以参与发送或接收On demand PRS/SRS的TRP属于服务基站以及相邻基站的情况进行说明。
第一网元在接收到终端设备发送的定位QoS信息后,可以根据定位QoS信息确定初始定位辅助数据,并将该初始定位辅助数据发送给第一网络设备,也可以直接将接收到的定位QoS信息发送给第一网络设备,以使第一网络设备根据定位QoS信息确定定位辅助数据。
对于第一网元确定初始定位辅助数据的情况,也即第一网元发送的第二消息中包括与定位QoS信息对应的初始定位辅助数据来说,在第一网元中预先存储有定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,其中,定位参考信号的配置参数包括PRS/SRS的频域带宽X、PRS/SRS的时域正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号个数Y、PRS波束宽度Z、Muting机制开启标志、参考信号周期T1和测量上报周期T2等。另外,每个配置参数均对应有自己的门限值,如PRS/SRS的频域带宽X对应的门限值为X_th,OFDM符号个数Y对应的门限值为Y_th,PRS波束宽度Z对应的门限值为Z_th,参考信号周期T1的门限值为T1_th,测量上报周期T2的门限值为T2_th,其中,上述门限值的具体取值与终端设备所能支持的能力有关,也即终端设备的能力不同,上述门限值的具体取值不同。可以理解,终端设备所能支持的能力,包括终端设备所具有的能力,或者终端设备对数据或信息处理的能力,或者终端设备所能支持的数据的处理方式或者算法等。
示例性的,上述定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系可以是预先通过仿真的方式或者根据已有的测试结果确定出的。
示例性的,表1中示出了一种可能的定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系:
表1
Figure PCTCN2022076373-appb-000001
Figure PCTCN2022076373-appb-000002
其中,表1中的定位精度高可以理解为定位精度大于第一预设值,定位精度低可以理解为定位精度不大于第一预设值,定位时延高可以理解为定位时延大于第二预设值,定位时延低可以理解为定位时延不大于第二预设值,高速场景可以理解为终端设备的移动速度大于第三预设值,例如高铁、地铁或者轻轨场景中,低速场景可以理解为终端设备的移动速度不大于第三预设值,例如跑步场景等。
需要进行说明的是,上述定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,除了采用表1中所示的表格形式进行存储之外,还可以采用协议进行显示定义,或者通过函数的方式进行定义,例如,通过如下公式(1)进行定义:
定位参考信号的配置参数Y_set=f(定位QoS信息X1_set,终端设备的能力信息X2);         (1)
其中,终端设备的能力信息X2用于确定不同的门限值。因此,若终端设备发送的第一消息中还包括有终端设备的能力信息时,第一网元将根据接收到的能力信息, 更新或者调整配置参数对应的门限值。例如,若终端设备能够处理数据的能力较强,则可以将配置参数对应的门限值更新为较大值,若终端设备能够处理数据的能力较弱,则可以将配置参数对应的门限值更新为较小值等。另外,还可以根据预先设置的终端设备的能力信息与配置参数对应的门限值之间的对应关系,更新第一消息中包括的终端设备的能力信息所对应的门限值。
示例性的,终端设备可以将上述终端设备的能力信息携带在第一消息中发送给第一网元,也可以携带在其他消息中发送给第一网元,对此本申请实施例不做限制。
由于第一网元可以根据终端设备的能力信息,对配置参数对应的门限值进行更新,由此可以避免所有的终端设备均采用同一个门限值的现象,不仅提高了配置参数门限值选择的灵活性,而且针对每个终端设备,可以确定不同的门限值,提高了定位辅助数据的准确性。
进一步的,第一网元中除了保存有上述如表1的对应关系和/或公式(1)中的对应关系之外,还存储有定位QoS信息和定位方法之间的对应关系,其中,定位方法包括上行定位方法、下行定位方法和上下行定位方法,如多站往返时间(Multi Round-Trip Time,Multi-RTT)。
第一网元在接收到终端设备发送的定位QoS信息后,将根据预先存储的定位QoS信息和定位方法之间的对应关系,确定所采用的定位方法。另外,还需要根据该定位方法确定定位参考信号的配置参数,例如,若定位方法为上行定位方法,则定位参考信号的配置参数将包括PRS的频域带宽、PRS的OFDM符号个数、PRS波束宽度、Muting机制开启标志、参考信号周期T1和测量上报周期T2等。若定位方法为下行定位方法,则定位参考信号的配置参数将包括SRS的频域带宽、SRS的OFDM符号个数、Muting机制开启标志、参考信号周期T1和测量上报周期T2等,若定位方法为上行和下行联合(即上行+下行)定位方法,则定位参考信号的配置参数将包括PRS的频域带宽、SRS的频域带宽、PRS的OFDM符号个数、SRS的OFDM符号个数、PRS波束宽度、Muting机制开启标志、参考信号周期T1和测量上报周期T2等。
本实施例中以上行定位方法来说明,第一网元在确定出定位参考信号的配置参数后,将根据如表1或者公式(1)中所示的定位QoS信息、定位参考信号的配置参数和所述配置参数对应的门限值之间的对应关系,确定出与定位QoS信息对应的配置参数的取值,并将该取值确定为初始定位辅助数据。
举例来说,对于定位QoS信息为定位精度高、定位时延低,且终端设备应用于高速场景中时,第一网元根据定位QoS信息确定出定位方法为上行定位方法,按照表1中的对应关系,第一网元确定出的初始定位辅助数据为:PRS的频域带宽大于门限值X_th,PRS的时域OFDM符号个数小于门限值Y_th,PRS的波束宽度小于门限值Z_th,Muting机制开启标志为YES、参考信号周期T1小于门限值T1_th、测量上报周期T2小于门限值T2_th。
在本实施例中,第一网元可以根据预先存储的定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,确定与定位QoS信息对应的配置参数的取值,并将该取值确定为初始定位辅助数据,由此可以将定位辅助数据和终端设备的定位QoS信息进行关联,避免了现有技术中针对所有的终端设备统一分配定位辅 助数据的现象,而是考虑了每个终端设备的定位QoS信息,为该终端设备分配对应的定位辅助数据,从而不仅可以保证该终端设备的定位精度和定位时延,而且可以降低系统资源的开销,减少资源的浪费。
进一步的,若第一网元接收到同一个基站管理的小区内的至少两个终端设备发送的第一消息,第一网元可以先获取各终端设备各自的优先级,这样,在根据预先存储的定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,确定与定位QoS信息对应的配置参数的取值时,会将至少两个终端设备中,优先级最高或最低的终端设备的定位QoS信息确定为目标定位QoS信息,再根据预先存储的定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,确定与目标定位QoS信息对应的配置参数的取值。
具体的,上述终端设备的优先级,可以是携带在第一消息中发送给第一网元的,也可以是由第一网元根据各终端设备发送的定位QoS信息确定出的。
若至少两个终端设备各自对应的优先级不全相同,则第一网元可以根据各终端设备的优先级,将优先级最高或者最低的终端设备的定位QoS信息确定为目标定位QoS信息,其中,确定出的目标定位QoS信息将为所有终端设备共用的定位QoS信息。第一网元将根据定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,确定与该目标定位QoS信息所对应的配置参数的取值,并将该取值确定为初始定位辅助数据。
第一网元确定出初始定位辅助数据后,将该初始定位辅助数据发送给第一网络设备。
可以理解的是,第一网元也可以将确定出的各终端设备的优先级发送给第一网络设备,并由第一网络设备根据优先级确定目标定位QoS信息。
在本实施例中,第一网元可以根据至少两个终端设备各自对应的优先级,确定最终的目标定位QoS信息,从而确定出相应的初始定位辅助数据,由此可以提高初始定位辅助数据的准确性。
另外,第一网元也可以直接将接收到的定位QoS信息发送给第一网络设备,由第一网络设备确定定位辅助数据。对于第一网络设备确定定位辅助数据的情况,将在下文进行详细的描述。
步骤303:第一网络设备根据定位QoS信息或初始定位辅助数据,确定第一目标定位辅助数据。
在本步骤中,若第二消息中包括终端设备的定位QoS信息,则第一网络设备在确定第一目标定位辅助数据时,可以根据预先存储的QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,确定与定位QoS信息对应的配置参数的取值,并根据配置参数的取值,确定第一目标定位辅助数据。
具体的,在一种可能的实现方式中,第一网元向第一网络设备发送的第二消息中还包括定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,这样,第一网络设备将会在本地存储该对应关系。
在该方式中,由于第一网元可以预先将定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系发送给第一网络设备,这样,在第一网络设 备本地将存储有该对应关系,第一网络设备在接收到第一网元发送的定位QoS信息后,可以直接根据该对应关系,确定初始定位辅助数据,而不需要在每次确定初始定位辅助数据时,均需要第一网元向第一网络设备发送该对应关系,从而可以提高确定初始定位辅助数据的效率。
在另一种可能的实现方式中,第一网元和第一网络设备中可以存储有定位QoS信息和定位参考信号的配置参数之间的对应关系,对于配置参数对应的门限值,可以采用预设值或者固定值。
在又一种可能的实现方式中,第一网元从终端设备接收的第一消息中包括终端设备的能力信息,第一网元可以根据终端设备的能力信息,确定定位QoS信息对应的定位参考信号的配置参数的门限值,并在第二消息中包括该门限值。在该方式中,网络设备中预先存储有定位QoS信息和定位参考信号的配置参数之间的对应关系,第一网元在接收到第一消息后,可以根据终端设备的能力信息和门限值之间的对应关系,以及该第一消息中包括的终端设备的能力信息,确定出各定位参考信号的配置参数所对应的门限值,并将该门限值携带在第二消息中发送给网络设备。网络设备在接收到各定位参考信号的配置参数所对应的门限值后,将结合预先存储的定位QoS信息和定位参考信号的配置参数之间的对应关系,确定出初始定位辅助数据。
另外,第一网元还可以根据终端设备的能力信息,更新配置参数对应的门限值,在更新完成后,可以将更新后的门限值携带在第二消息中发送给第一网络设备。
在本方式中,第一网元可以基于终端设备的能力信息,确定定位参考信号的配置参数的门限值,不仅提高了配置参数门限值选择的灵活性,而且针对每个终端设备,可以确定不同的门限值,提高了所确定的定位辅助数据的准确性。
进一步的,定位QoS信息、定位参考信号的配置参数和所述配置参数对应的门限值之间的对应关系,与表1或公式(1)中描述的对应关系类似,此处不再赘述。
第一网络设备在获取到定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系后,将确定与定位QoS信息对应的配置参数的取值。示例性的,第一网络设备可以直接将确定出的配置参数的取值,确定为第一目标定位辅助数据,也可以根据资源分配情况对该配置参数的取值进行调整,从而得到第一目标定位辅助数据。
在本方式中,第一网络设备可以根据定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,确定与定位QoS信息对应的配置参数的取值,从而根据该取值,确定第一目标定位辅助数据,由此可以针对每个终端设备的定位QoS信息,分别为每个终端设备分配对应的第一目标定位辅助数据,而不再是针对所有的终端设备统一分配定位辅助数据,这样,由于考虑了每个终端设备的定位QoS信息为该终端设备分配定位辅助数据,从而不仅可以保证该终端设备的定位精度和定位时延,而且可以降低系统资源的开销,减少资源的浪费。
若第二消息中包括与定位QoS信息对应的初始定位辅助数据,则第一网络设备可以直接将第一网元确定出的初始定位辅助数据确定为第一目标定位辅助数据,由此可以提高第一目标定位辅助数据确定的效率。另外,第一网络设备也可以根据资源的分配情况,对初始定位辅助数据进行调整,从而得到第一目标定位辅助数据,由此可以 提高资源的利用率。
示例性的,若第一网元接收到至少两个终端设备发送的第一消息,则第一网元会确定各终端设备的优先级,并将各终端设备的优先级发送给第一网络设备,第一网络设备根据各终端设备的优先级,可以将优先级最高或者最低的终端设备的定位QoS信息确定为目标定位QoS信息,并结合定位QoS信息、定位参考信号的配置参数和配置参数对应的门限值之间的对应关系,确定与目标定位QoS信息对应的配置参数的取值,从而确定出初始定位辅助数据。
步骤304:第一网络设备分别向第一网元和终端设备发送第一目标定位辅助数据,该第一目标定位辅助数据与定位QoS信息相关。
在本步骤中,第一网络设备在确定出第一目标定位辅助数据后,会将该第一目标定位辅助数据发送给第一网元。由于该第一目标定位辅助数据与定位QoS信息相关,因此,可以根据终端设备的定位QoS信息,为不同的终端设备分配不同的目标定位辅助信息,从而不仅可以保证该终端设备的定位精度和定位时延,而且可以降低系统资源的开销,减少资源的浪费。
进一步的,第一网络设备还会将该第一目标定位辅助数据以及定位方法发送给终端设备。
步骤305:第一网元向第二网络设备发送第一目标定位辅助数据。
在本步骤中,第二网络设备为终端设备的相邻基站。第一网元在接收到第一网络设备发送的第一目标定位辅助数据后,会向第二网络设备发送第一目标定位辅助数据。
步骤306:第一网元接收来自第一网络设备的第一定位测量值以及来自第二网络设备的第二定位测量值。
其中,第一定位测量值为第一网络设备根据第一目标定位辅助数据接收上行定位参考信号SRS-Pos后,对上行定位参考信号SRS-Pos进行测量后得到的,第二定位测量值为第二网络设备根据第一目标定位辅助数据接收上行定位参考信号SRS-Pos后,对上行定位参考信号SRS-Pos进行测量后得到的。
在本步骤中,若第一网元确定出的定位方法为上行定位方法,终端设备在接收到第一网络设备发送的第一目标定位辅助数据后,会根据该第一目标定位辅助数据,分别向第一网络设备和第二网络设备发送上行定位参考信号SRS-Pos。
对于第一网络设备来说,其将根据自身确定出的第一目标定位辅助数据,获取上行定位参考信号SRS-Pos的时频资源配置参数,从而根据该时频资源配置参数接收终端设备发送的上行定位参考信号SRS-Pos,并对接收到的上行定位参考信号SRS-Pos进行测量,得到第一定位测量值。进一步的,第一网络设备可以将确定出的第一定位测量值发送给第一网元。
对于第二网络设备来说,其将根据第一网元发送的第一目标定位辅助数据,获取上行定位参考信号SRS-Pos的时频资源配置参数,从而根据该时频资源配置参数接收终端设备发送的上行定位参考信号SRS-Pos,并对接收到的上行定位参考信号SRS-Pos进行测量,得到第二定位测量值。进一步的,第一网络设备可以将确定出的第一定位测量值发送给第一网元。
步骤307:第一网元根据第一定位测量值和第二定位测量值,确定终端设备的位置信息。
在本步骤中,第一网元获取到第一定位测量值和第二定位测量值后,将结合第一网络设备和第二网络设备的位置信息,从而解算出终端设备的位置信息。
本申请实施例提供的终端设备的定位方法,第一网元从终端设备接收到的第一消息中包括有定位QoS信息,第一网元可以根据该定位QoS信息确定初始定位辅助数据,并将该初始定位辅助数据发送给第一网络设备,或者第一网元可以直接将定位QoS信息发送给第一网络设备,以使第一网络设备根据初始定位辅助数据或定位QoS信息确定第一目标定位辅助数据,从而使得第一网元可以获取到与该第一目标定位辅助数据对应的定位测量值,以确定终端设备的位置信息。由于第一网络设备在为终端设备分配第一目标定位辅助数据时,可以考虑每个终端设备的定位QoS信息,针对每个终端设备的定位QoS信息,分别为每个终端设备分配对应的第一目标定位辅助数据,而不再是针对所有的终端设备统一分配定位辅助数据,这样,由于考虑了每个终端设备的定位QoS信息为该终端设备分配定位辅助数据,从而不仅可以保证该终端设备的定位精度和定位时延,而且可以降低系统资源的开销,减少资源的浪费。
图4为本申请另一实施例提供的终端设备的定位方法的信令流程图,本实施例中对LMF采用下行定位方法确定终端设备的位置信息的方案进行详细说明。如图4所示,该方法包括:
步骤401:第一网元从终端设备接收第一消息,该第一消息中包括定位QoS信息。
步骤401与步骤301类似,具体内容可以参照步骤301的描述,此处不再赘述。
步骤402:第一网元分别向第一网络设备和第二网络设备发送第二消息,该第二消息中包括定位QoS信息或与定位QoS信息对应的初始定位辅助数据。
其中,第一网络设备包括终端设备的服务基站,第二网络设备包括终端设备的相邻基站。示例性的,当参与发送或接收按需分配(On demand)PRS/SRS的传输接收点(Transmission Reception Point,TRP)都属于同一个服务基站时,由服务基站确定按需分配(On demand)PRS/SRS的时频资源配置参数,也即确定目标定位辅助数据。当参与发送或接收On demand PRS/SRS的TRP属于服务基站以及相邻基站时,由服务基站和相邻基站分别确定各自的按需分配(On demand)PRS/SRS的时频资源配置参数,也即服务基站和相邻基站分别确定各自对应的目标定位辅助数据。本申请中均以参与发送或接收On demand PRS/SRS的TRP属于服务基站以及相邻基站的情况进行说明。
第一网元在接收到终端设备发送的定位QoS信息后,根据QoS信息确定初始定位辅助数据的方式,与步骤302中类似,具体内容可以参照步骤302的描述,此处不再赘述。
第一网元确定出初始定位辅助数据后,将该初始定位辅助数据发送给第一网络设备和第二网络设备。
可以理解的是,对于多个终端设备的情况,第一网元也可以将确定出的各终端设备的优先级发送给第一网络设备和第二网络设备,并由第一网络设备和第二网络设备各自根据优先级确定目标定位QoS信息。在确定出目标定位QoS信息后,第二网络设 备根据其自身确定出的目标定位QoS信息,确定初始定位辅助数据的方式,与第一网络设备确定初始定位辅助数据的方式类似,此处不再赘述。
另外,第一网元也可以直接将接收到的定位QoS信息发送给第一网络设备和第二网络设备,由第一网络设备和第二网络设备确定定位辅助数据。对于第一网络设备和第二网络设备确定定位辅助数据的情况,将在下文进行详细的描述。
步骤403:第一网络设备根据定位QoS信息或初始定位辅助数据,确定第一目标定位辅助数据,第二网络设备根据定位QoS信息或初始定位辅助数据,确定第二目标定位辅助数据。
若第二消息中包括终端设备的定位QoS信息,则第一网络设备将根据定位QoS信息确定第一目标定位辅助数据,第二网络设备将根据定位QoS信息确定第二目标定位辅助数据。其中,第一网络设备和第二网络设备确定目标定位辅助数据的方式类似,均可以参照步骤303中的描述,此处不再赘述。
若第二消息中包括与定位QoS信息对应的初始定位辅助数据,则第一网络设备可以直接将第一网元确定出的初始定位辅助数据确定为第一目标定位辅助数据,由此可以提高第一目标定位辅助数据确定的效率。另外,第一网络设备也可以根据资源的分配情况,对初始定位辅助数据进行调整,从而得到第一目标定位辅助数据,由此可以提高资源的利用率。
同样的,对于第二网络设备来说,第二网络设备可以直接将第一网元确定出的初始定位辅助数据确定为第二目标定位辅助数据,由此可以提高第二目标定位辅助数据确定的效率。另外,第二网络设备也可以根据资源的分配情况,对初始定位辅助数据进行调整,从而得到第二目标定位辅助数据,由此可以提高资源的利用率。
步骤404:第一网元分别接收第一网络设备发送的第一目标定位辅助数据以及第二网络设备发送的第二目标定位辅助数据。
其中,第一目标定位辅助数据和第二目标定位辅助数据均与定位QoS信息相关。
由于该第一目标定位辅助数据和第二目标定位辅助数据均与定位QoS信息相关,因此,可以根据终端设备的定位QoS信息,为不同的终端设备分配不同的目标定位辅助信息,从而不仅可以保证该终端设备的定位精度和定位时延,而且可以降低系统资源的开销,减少资源的浪费。
步骤405:第一网元向终端设备发送第一目标定位辅助数据和第二目标定位辅助数据。
在本步骤中,第一网元在接收到第一目标定位辅助数据和第二目标定位辅助数据后,会将该第一目标定位辅助数据和第二目标定位辅助数据发送给终端设备。
步骤406:第一网元接收终端设备发送的第一定位测量值和第二定位测量值。
其中,第一定位测量值为终端设备根据第一目标定位辅助数据接收第一网络设备发送的第一下行定位参考信号,并对第一下行定位参考信号进行测量得到的,第二定位测量值为终端设备根据第二目标定位辅助数据接收第二网络设备发送的第二下行定位参考信号,并对第二下行定位参考信号进行测量得到的。
在本步骤中,若第一网元确定出的定位方法为下行定位方法,终端设备在接收到第一网元发送的第一目标定位辅助数据和第二目标定位辅助数据后,会基于第一目标 定位辅助数据,确定第一下行定位参考信号PRS的时频资源配置参数,并根据该第一下行定位参考信号PRS的时频资源配置参数,接收第一网络设备发送的第一下行定位参考信号PRS,并对该第一下行定位参考信号PRS进行测量,从而得到第一定位测量值。同样的,终端设备可以基于第二目标定位辅助数据,确定第二下行定位参考信号PRS的时频资源配置参数,并根据该第二下行定位参考信号PRS的时频资源配置参数,接收第二网络设备发送的第二下行定位参考信号PRS,并对该第二下行定位参考信号PRS进行测量,从而得到第二定位测量值。
终端设备在确定出第一定位测量值和第二定位测量值后,可以将该第一定位测量值和第二定位测量值发送给第一网元。
步骤407:第一网元根据第一定位测量值和第二定位测量值,确定终端设备的位置信息。
在本步骤中,第一网元获取到第一定位测量值和第二定位测量值后,将结合第一网络设备和第二网络设备的位置信息,从而解算出终端设备的位置信息。
本申请实施例提供的终端设备的定位方法,第一网元从终端设备接收到的第一消息中包括有定位QoS信息,第一网元可以根据该定位QoS信息确定初始定位辅助数据,并将该初始定位辅助数据发送给第一网络设备和第二网络设备,或者第一网元可以直接将定位QoS信息发送给第一网络设备和第二网络设备,以使第一网络设备和第二网络设备根据初始定位辅助数据或定位QoS信息确定第一目标定位辅助数据和第二目标定位辅助数据,从而使得第一网元可以获取到与该第一目标定位辅助数据对应的第一定位测量值,以及与第二目标定位辅助数据对应的第二定位测量值,以确定终端设备的位置信息。由于第一网络设备和第二网络设备在为终端设备分配第一目标定位辅助数据时,可以考虑每个终端设备的定位QoS信息,针对每个终端设备的定位QoS信息,分别为每个终端设备分配对应的第一目标定位辅助数据,而不再是针对所有的终端设备统一分配定位辅助数据,这样,由于考虑了每个终端设备的定位QoS信息为该终端设备分配定位辅助数据,从而不仅可以保证该终端设备的定位精度和定位时延,而且可以降低系统资源的开销,减少资源的浪费。
下面,分别以具体的示例,针对定位方法为上行定位、下行定位以及上下行联合(上行+下行)定位的实现方式进行详细说明。
