Description

用户设备位置信息上报的方法、用户设备及网络设备 技术领域
本申请涉及通信技术领域，尤其涉及一种用户设备(user equipment，UE)位置信息上报的方法、用户设备及网络设备。
背景技术
随着通信技术的快速发展，为了向用户提供更好的通信服务，下行高精度定位成为5G技术的一个重要研究方向。例如，在增强移动宽带(enhanced mobile broadband，eMBB)场景下，定位精度的要求通常是：室内定位精度误差小于1米，室外定位精度误差小于10米。
常规的下行定位是通过分析用户设备UE对参考信号的测量结果确定的。例如，参考信号可以是定位参考信号(positioning reference signal，PRS)。具体的，UE可以周期性地向定位管理设备上报对参考信号的测量结果。
但是，现有技术中，UE只有在连接(connected)状态下才可以向定位管理设备上报测量结果。对于处于空闲(idle)状态或者去激活(inactive)状态的UE，用户设备UE需要周期性地由空闲状态或去激活状态进入连接状态，才能向定位管理设备上报对参考信号的测量结果。而UE进入连接状态，会增大电量消耗。
并且，UE进入连接状态，网络设备需要为UE分配链路资源。因此，采用常规的下行定位方法，还可能导致链路资源的浪费。

具体实施方式
本申请提供一种用户设备位置信息上报的方法，该方法应用于定位管理设备、接入和移动管理设备或第三方设备对用户设备定位的过程。具体的，用户设备可以根据定位管理设备(如LMF、LMC)的指示，在满足预设触发条件时(如用户设备运动时)，上报用户设备UE对接收到的多个定位参考信号的测量结果。定位管理设备(如LMF、LMC)可以根据UE上报的测量结果确定UE的位置。
本申请提供的用户设备位置信息上报的方法可以应用于各种通信系统，例如：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、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)等，本申请中涉及的5G移动通信系统包括非独立组网(non-standalone，NSA)的5G移动通信系统或独立组网(standalone，SA)的5G移动通信系统。本申请提供的技术方案还可以应用于未来的通信系统，如第六代移动通信系统。通信系统还可以是陆上公用移动通信网(Public Land Mobile Network，PLMN)网络、设备到设备(device-to-device，D2D)通信系统、机器到机器(machine to machine，M2M)通信系统、物联网(Internet of Things，IoT)通信系统或者其他通信系统。
请参考图1，图1示出了四种适用于UE定位的网络架构的示例示意图。如图1中的(a)所示，终端设备通过LTE-Uu和/或NR-Uu接口分别经由下一代基站(next-generation eNodeB，ng-eNB)和/或gNB连接到NG-RAN。NG-RAN可以包括一个或多个ng-eNB；NG-RAN还可以包括一个或多个传输接收点(trasmission/reception point，TRP)；NG-RAN也可以包括一个或多个gNB；NG-RAN还可以包括一个或多个ng-eNB以及gNB。其中，Ng-eNB是LTE通信系统中的基站。gNB是NR通信系统中的基站。Ng-eNB与gNB之间通过Xn接口进行通信。NG-RAN与接入和移动管理网元(access and mobility management function，AMF)之间通过NG-C接口进行通信。在UE定位的过程中，AMF相当于基站与定位管理功能网元(location management function，LMF)之间通信的路由器，用于实现接入管理等功能。LMF用于实现定位管理等功能，包括对UE位置信息的上报过程进行管理，以及对UE定位等。AMF与LMF间通过NLs接口进行通信。
可选地，一个LMF还可以与一个增强的服务移动定位中心(enhanced serving mobile location center，E-SMLC)有信令连接，E-SMLC是E-UTRA定位架构中负责处理定位请求的核心网实体，例如对特定的UE定位和发送辅助数据给UE等，因此LMF与E-SMLC之间的信令连接可以使能LMF从E-UTRA系统获得定位数据。
可选地，一个LMF也可以与一个安全用户平面定位平台(secure user plane location platform，SLP)有信令连接。其中，SLP是用户面定位中负责定位的SUPL(secure user plane location)实体，因此LMF与SLP的信令连接可以使得LMF扩展支持用户面的定位方案。其中，SUPL是开放移动联盟(open mobile alliance，OMA)规定的定位协议架构。
如图1中的(b)所示，gNB和/或ng-eNB中还可以集成有定位管理组件(location management component，LMC)。
如图1中的(c)所示，LMC可以独立于gNB和ng-eNB集成在NG-RAN中，作为NG-RAN的一个节点(node)。
其中，LMC作为NG-RAN的一个节点(node)，可以承担LMF的一部分功能。在本申请中，在UE位置信息上报的过程中，UE可以将参考信号的测量结果上报给LMC。无需与核心网进行交互，可以节省信令开销，并降低定位时延。
在一些可能的结构中，接入网设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的。其中，CU也可以称为控制单元(control unit)。通过CU-DU的结构可以将接入网设备的协议层拆分开，将部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。例如，可以将无线资源控制(radio resource control，RRC)，业务数据适应协议(service data adaptation protocol，SDAP)以及分组数据汇聚协议(packet data convergence protocol，PDCP)层部署在CU；其余的无线链路控制(radio link control，RLC)层、介质访问控制(media access control，MAC)层以及物理层(Physical)部署在DU。CU和DU之间通过F1接口连接。CU代表gNB通过NG接口和核心网连接。
可选地，CU还可以采用控制面(control plane)实体和用户面(user plane，UP)网元分离的结构，由一个控制面网元管理多个用户面网元。
在一个示例中，一个gNB可以有一个gNB-CU-CP，多个gNB-CU-UP和多个gNB-DU。一个gNB-CU-CP通过E1接口连接多个gNB-CU-UP，一个gNB-CU-CP可以通过F1-C接口连接多个gNB-DU，一个gNB-DU可以通过F1-U接口连接多个gNB-CU-UP。
如图1中的(d)所示，gNB可以包括gNB-DU和gNB-CU。其中，gNB-DU和gNB-CU之间通过F1接口连接，gNB-CU通过Xn-C接口与ng-eNB连接。gNB中还集成有LMC。
应理解，上述图1中的(a)、图1中的(b)、图1中的(c)和图1中的(d)所示的定位系统中，可以包括一个或多个gNB，一个或多个UE。单个gNB可以向单个UE或多个UE传输数据或控制信令。多个gNB也可以同时为单个UE传输数据或控制信令。
还应理解，上述图1中的(a)、图1中的(b)、图1中的(c)和图1中的(d)所示定位系统中包括的设备或功能节点只是示例性地描述，并不对本申请构成限定，事实上，图1中的(a)、图1中的(b)、图1中的(c)和图1中的(d)所示的定位系统中还可以包含其他与图中示意的设备或功能节点具有交互关系的网元或设备或功能节点，这里不作具体限定。
还应理解，在本申请中，定位管理设备可以是图1中的(a)、图1中的(b)、图1中的(c)和图1中的(d)所示的LMF，也可以是图1中的(b)、图1中的(c)和图1中的(d)所示的LMC。定位管理设备还可以是其他具有定位管理功能的网络设备。图1中的(a)、图1中的(b)图1中的(c)和图1中的(d)仅以定位管理设备是LMF或者LMC作为示例，本申请对定位管理设备不做具体限定。
本申请中的接入网设备可以是如图1中的(a)、图1中的(b)图1中的(c)和图1中的(d)所示的Ng-eNB、gNB或TRP。还可以是第三代合作伙伴计划(3rd generation partnership project，3GPP)所定义的基站。例如，GSM或CDMA系统中的基站收发台(base transceiver station，BTS)，WCDMA系统中的节点B(nodeB，NB)，LTE系统中的演进型节点B(evolved NodeB，eNB/eNodeB)等。
此外，当eNB接入NR的核心网或者下一代核心网(Next Genaeration Core,NGC)或者5G核心网(5th Generation Core Network，5GC)时，eNB也可以称为eLTE eNB。具体地，eLTE eNB是在eNB的基础上演进的LTE基站设备，可以直接连接5G CN，eLTE eNB也属于NR中的基站设备。
或者，接入网设备还可以是无线端点(wireless terminal，WT)。例如接入点(access point，AP)或者接入控制器(access controller，AC)，或者其他具有与用户设备、及核心网有通信能力的网络设备。例如，中继设备、车载设备、智能穿戴设备等。本申请对接入网设备的类型不做限定。

下面结合图3对UE 300的各个部件进行具体的介绍：
处理器301是UE 300的控制中心，利用各种接口和线路连接UE 300的各个部分，通过运行或执行存储在存储器303内的应用客户端程序(以下可以简称App)，以及调用存储在存储器303内的数据，执行UE 300的各种功能和处理数据。在一些实施例中，处理器301可以是一个通用中央处理器(central processing unit，CPU)，微处理器，特定应用集成电路(application-specific integrated circuit，ASIC)，或一个或多个用于控制本申请方案程序执行的集成电路，处理器301可以包括一个或多个CPU；举例来说，处理器301可以是麒麟360芯片。

在本申请中，信号接收装置还用于测量UE所处网络环境的接收信号参数(如RSRP、RSRQ、RSTD、NRSRP或NRSRQ等)。在UE确定传感器测量到UE的接收信号参数数的变化值大于预设阈值时，UE可以推测UE发生了运动，则UE触发上报定位参考信号的测量结果，用于定位管理设备对UE定位。
存储器303用于存储应用程序以及数据，存储器303可以是只读存储器(read-only memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，随机存取存储器(random access memory，RAM)或者可存储信息和指令的其他类型的动态存储设备，也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此。处理器301通过运行存储在存储器303的应用程序以及数据，执行UE 300的各种功能以及数据处理。存储器303主要包括存储程序区以及存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)；存储数据区可以存储根据使用UE 300时所创建的数据(比如音频数据、电话本等)。其中，存储器303可以存储用于实现两个模块化功能的指令：接收指令和连接指令，并由处理器301来控制执行。处理器301用于执行存储器303中存储的计算机执行指令，从而实现本申请下述提供的用户设备位置信息上报的方法。此外，存储器303可以包括高速随机存取存储器，还可以包括非易失存储器，例如磁盘存储器件、闪存器件或其 他易失性固态存储器件等。存储器303可以存储各种操作系统，例如，iOS操作系统，Android操作系统等。
UE 300还可以包括至少一种传感器306，比如光传感器、运动传感器(包括加速度传感器、陀螺仪传感器等)、气压传感器、磁传感器以及其他传感器。具体地，光传感器可包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节触摸屏304的显示器的亮度，接近传感器可在UE 300移动到耳边时，关闭显示器的电源。作为运动传感器的一种，加速度传感器可检测各个方向上(一般为三轴)加速度的大小，静止时可检测出重力的大小及方向，可用于识别智能手机姿态的应用(比如横竖屏切换、相关游戏、磁力计姿态校准)、振动识别相关功能(比如计步器、敲击)等。陀螺仪传感器可以用于确定UE 300的运动姿态。在本申请中，可以通过陀螺仪传感器确定UE 300的旋转方向和旋转角速度。磁传感器可以把磁场、电流、应力应变、温度、光等外界因素引起敏感元件磁性能变化转换成电信号，以这种方式来检测相应物理量的器件。本申请中，通过磁传感器可以测量出UE 300与东南西北四个方向的夹角。气压传感器用于测量气压。在一些实施例中，UE 300可以通过气压传感器测得的气压值计算海拔高度，辅助定位和导航。至于UE 300还可配置的湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。
在本申请中，在UE确定传感器测量到UE的运动参数的变化值大于预设阈值时，UE可以推测UE发生了运动，则UE可以触发上报定位参考信号的测量结果，用于定位管理设备对UE定位。
定位装置308，用于为UE 300提供地理位置。可以理解的是，该定位装置308具体可以是全球定位系统(GPS)、北斗卫星导航系统、伽利略卫星导航系统或俄罗斯GLONASS等定位系统的接收器。定位装置308在接收到上述定位系统发送的地理位置后，将该信息发送给处理器301进行处理，或者发送给存储器303进行保存。在另外的一些实施例中，该定位装置308还可以是辅助全球卫星定位系统(AGPS)的接收器，AGPS系统通过作为辅助服务器来协助定位装置308完成测距和定位服务，在这种情况下，辅助定位服务器可以通过无线通信网络与UE 300的定位装置308(即GPS接收器)通信而提供定位协助。在另外的一些实施例中，该定位装置308也可以是基于Wi-Fi接入点的定位技术。由于每一个Wi-Fi接入点都有一个全球唯一的MAC地址，用户设备在开启Wi-Fi的情况下即可扫描并收集周围的Wi-Fi接入点的广播信号，因此可以获取到Wi-Fi接入点广播出来的MAC地址；用户设备将这些能够标示Wi-Fi接入点的数据(例如MAC地址)通过无线通信网络发送给位置服务器，由位置服务器检索出每一个Wi-Fi接入点的地理位置，并结合Wi-Fi广播信号的强弱程度，计算出该用户设备的地理位置并发送到该用户设备的定位装置308中。
在本申请中，在UE确定传感器测量到UE的位置参数的变化值大于预设阈值时，UE可以推测UE发生了运动，则UE可以触发上报定位参考信号的测量结果，用于定位管理设备对UE定位。
尽管图3未示出，UE 300还可以包括摄像头(前置摄像头和/或后置摄像头)、闪光灯、微型投影装置、近场通信(NFC)装置等，在此不再赘述。
应理解，上述图3所示用户设备包括的硬件模块只是示例性地描述，并不对本申 请构成限定，事实上，图3所示的用户设备中还可以包含其他与图中示意的硬件模块具有交互关系的其他硬件模块，这里不作具体限定。
为便于理解，以下对本申请可能出现的概念和术语进行解释。
1、连接(connected)状态：也称连接态。连接状态是指无线资源控制(radio resource control，RRC)连接已建立，因此也称RRC_CONNECTED。当UE处于连接状态时，UE与接入网(如基站)以及核心网(如AMF)之间的连接均建立，若有数据需要传输，可以直接通过已建立的连接完成。其中，RRC连接用于处理UE和接入网之间的控制面消息。
2、去激活(inactive)状态：也称去激活态(RRC_INACTIVE)或者第三态。去激活状态是指UE与接入网(如基站)之间的RRC连接已断开，但是UE的接入网(如基站)与核心网(如AMF)之间的连接未断开。当UE处于去激活状态时，若有数据需要传输，需要先恢复UE与接入网(如基站)之间的连接，才能进行数据传输。
3、空闲(idle)状态：也称空闲态(RRC_IDLE)。空闲状态是指UE与接入网(如基站)之间的RRC连接未建立，且UE的接入网(如基站)与核心网(如AMF)之间的连接未建立。当UE处于空闲状态时，若有数据需要传输，需要先建立UE与接入网(如基站)之间的连接，以及UE的接入网(如基站)与核心网(如AMF)之间的连接，才能进行数据传输。
请参考图4，图4示出了连接(connected)状态、去激活(inactive)状态和空闲(idle)状态的状态转换示意图。如图4所示，从空闲状态进入连接状态时，需要建立UE和接入网设备之间的连接，以及建立UE的上下文。从连接状态进入去激活状态时，会断开UE和接入网设备之间的连接，UE的接入网设备和核心网设备之间的连接继续保持。从去激活状态进入空闲状态时，会释放UE的上下文。关于空闲状态、去激活状态以及连接状态的具体介绍，可以参考常规技术中的解释和说明，本申请不做赘述。
本申请实施例以下以具有图3所示硬件结构的UE为例，对本申请实施例提供的UE位置信息上报的方法进行介绍。
如图5所示，本申请实施例提供的UE位置信息上报的方法可以包括S501-S503：
S501、UE接收第一消息。第一消息包括运动触发条件(如motionTrigger)。运动触发条件用于触发UE基于运动上报定位参考信号的测量结果。
其中，定位参考信号的测量结果用于对UE定位。关于定位参考信号的测量结果的具体介绍，将在下文S503中详细说明。
在本申请实施例中，UE可以从LMF接收上述第一消息。UE也可以从LMC，定位管理单元(location management unit，LMU)等具有定位管理功能的设备接收第一消息。本申请实施例对第一消息的来源不做具体限定。
示例性的，第一消息可以是请求位置消息。其中，请求位置消息可以是LMF或LMC等定位管理设备自主触发的，也可以是LMF或LMC等定位管理设备基于接入和移动管理设备(如AMF)或者定位服务实体(location service entities，LCS entities)的请求触发的，本申请实施例对于定位管理设备发送请求位置消息的触发主体不做限定。
S502、UE确定UE满足上述运动触发条件。
其中，UE确定UE满足上述运动触发条件可以包括：UE确定UE预设参数的变化值大于预设阈值。UE预设参数包括但不限于UE的位置参数、UE的运动参数或UE的接收信号参数中的至少一个。预设阈值大于或等于0。关于预设阈值的介绍，将在下文中具体说明。
在一种可能的情况下，在UE确定UE满足上述运动触发条件时，UE处于空闲状态或者去激活状态。
在另一种可能的情况下，UE确定UE满足上述运动触发条件时，UE处于连接状态。
S503、UE上报定位参考信号的测量结果。
其中，UE可以向LMF上报定位参考信号的测量结果。UE也可以向LMC，LMU等网元上报定位参考信号的测量结果。具体的，若UE在步骤S501从LMF接收第一消息(如请求位置消息)，则UE向LMF上报定位参考信号的测量结果。若UE在S501从LMC接收第一消息，则UE向LMC上报定位参考信号的测量结果。若UE在S501从LMU接收第一消息，则UE向LMU上报定位参考信号的测量结果。
在本申请实施例中，UE上报的定位参考信号的测量结果可以包括UE在确定满足运动触发条件之后，通过测量多个定位参考信号得到的定位参考信号的测量结果，和/或UE在确定满足运动触发条件之前，通过测量多个定位参考信号得到的定位参考信号的测量结果。
需要说明的是，若预设阈值等于0，则UE上报的定位参考信号的测量结果可以包括UE在确定满足运动触发条件之后，通过测量多个定位参考信号得到的定位参考信号的测量结果，或UE在确定满足运动触发条件之前，通过测量多个定位参考信号得到的定位参考信号的测量结果。
若预设阈值大于0，则UE上报的定位参考信号的测量结果可以包括UE在确定满足运动触发条件之后，通过测量多个定位参考信号得到的定位参考信号的测量结果，和/或UE在确定满足运动触发条件之前，通过测量多个定位参考信号得到的定位参考信号的测量结果。
示例性的，UE可以按照预设测量周期周期性测量多个定位参考信号，并保存定位参考信号的测量结果。或者，UE可以在第一预设时间段内测量多个定位参考信号，并保存定位参考信号的测量结果。其中，测量定位参考信息的预设测量周期和/或第一预设时间段可以是定位管理设备(如LMF或LMC等)指示的。示例性的，第一消息还可以包括测量定位参考信息的预设测量周期和/或第一预设时间段。
其中，定位参考信号(positioning reference signal，PRS)测量结果可以包括但不限于：参考信号接收功率(reference signal received power，RSRP)、参考信号接收质量(reference signal received quality，RSRQ)、参考信号时间差(reference signal time difference，RSTD)、窄带参考信号接收功率(narrowband reference signal reception power，NRSRP)或窄带参考信号接收质量(narrowband reference signal reception quality，NRSRQ)中的一个或多个。
可选的，定位参考信号的测量结果也可以包括UE根据定位参考信号计算的UE的定位计算信息(如position estimate)。定位管理设备(如LMF或LMC等)可以基 于UE上报的该定位计算信息(如position estimate)进一步计算得到对UE的定位结果，也可以直接将UE上报的该定位计算信息(如position estimate)作为对UE的定位结果。
需要说明的是，本申请实施例仅以UE在满足运动触发条件时上报PRS测量结果作为示例。事实上，UE还可以对探测参考信号(sounding reference signal，SRS)、信道状态信息(channel state information，CSI)或者同步信号和物理广播信道块(Synchronization Signal and Physical broadcast channel block，SSB)等定位相关参考信号进行测量，并在满足运动触发条件时，上报SRS测量结果、CSI测量结果或者SSB测量结果等用于对UE定位的测量信息。本申请实施例对UE采取的测量方式以及UE上报的测量结果的具体内容不做限定。
进一步的，若UE确定UE满足上述运动触发条件时，UE处于空闲状态或者去激活状态，步骤S503可以包括以下步骤(1)或(2)：
(1)UE在空闲状态或者去激活状态下，向定位管理设备(如LMF或LMC等)上报定位参考信号的测量结果。
示例性的，UE在空闲状态或者去激活状态下，可以在满足运动触发条件时，基于早期数据传输(early data transmission，EDT)向定位管理设备(如LMF或LMC等)上报定位参考信号的测量结果。
或者，UE在空闲状态或者去激活状态下，还可以过空闲状态或者去激活状态的预配置资源向定位管理设备(如LMF或LMC等)上报定位参考信号的测量结果。其中，预配置资源可以是系统消息广播的也可以是RRC专用信令下发的。或者，UE还可以采用其他早期数据传输方式，或通过其他空闲状态或者去激活状态下的传输资源上报定位参考信号的测量结果，本申请实施例对UE在空闲状态或者去激活状态下上报对定位参考信号的测量结果的方法不做具体限定。
(2)UE从空闲状态或者去激活状态进入连接状态。UE在连接状态下，向定位管理设备(如LMF或LMC等)上报定位参考信号的测量结果。
其中，UE从空闲状态进入连接状态具体可以包括：UE与接入网设备(如Ng-eNB或gNB)建立RRC连接，以及UE通过接入网设备(如Ng-eNB或gNB)与接入和移动管理设备(如AMF)建立连接。
UE从去激活状态进入连接状态具体可以包括：UE与接入网设备(如Ng-eNB或gNB)建立RRC连接。
若UE确定UE满足上述运动触发条件时，UE处于连接状态，S503可以包括：UE在连接状态下，向定位管理设备(如LMF或LMC等)上报定位参考信号的测量结果。
在另一种可选的实现方式，当定位管理设备(如LMC)位于NG-RAN节点(node)中时(如图1中的(b)、图1中的(c)或图1中的(d)所示)，UE通过发起随机接入进入连接状态，并通过RRC连接建立完成(RRCSetupComplete)消息向接入网设备(如Ng-eNB、gNB或TRP等)指示UE有定位测量结果。接入网设备(如Ng-eNB、gNB或TRP等)根据接收到的来自UE的指示向UE请求定位测量结果，UE再向接入网设备(如Ng-eNB、gNB或TRP等)发送定位参考信号的测量结果，接入网设备 (如Ng-eNB、gNB或TRP等)再将定位测量结果转发给定位管理设备(如LMC)。
进一步的，如图6所示，在步骤S502之前，本申请实施例提供的UE位置信息上报的方法还可以包括S504：
S504、UE测量得到预设参数。
在本申请实施例中，UE可以周期性测量，或者在第二预设时间段内得到预设参数(如位置参数、运动参数或接收信号参数等)，并将得到的预设参数存储。在预设参数的变化值大于预设阈值时，确定UE满足运动触发条件。
具体的，UE可以根据预设测量周期(如每秒/每30秒/每分钟/每小时等)或第二预设时间段(如上午8：00-9：00和中午12：00-12：30等)，采用预设测量方式测量得到预设参数。其中，测量方式可以包括但不限于传感器测量、卫星测量或信号接收装置测量中的一个或多个。示例性的，采用传感器测量的方式可以得到UE的运动参数，如UE移动的方向和距离，UE翻转的方向和角度等。采用卫星测量的方式可以得到UE的位置参数，如UE所处的经纬度等。采用信号接收装置测量的方式可以得到UE的接收信号参数，如UE所处网络环境的RSRP、RSRQ、RSTD、NRSRP或NRSRQ等。
可以理解，无论是UE的运动参数的变化值大于预设阈值，还是UE的位置参数的变化值大于预设阈值，或者接收信号参数的变化值大于预设阈值，本质上都是UE运动造成的结果，或者说是UE位置发生变化的结果。在UE运动或者UE位置发生变化时，触发UE上报参考信号测量结果，使得定位管理设备(如LMF或LMC等)对UE定位时很有必要的。
需要说明的是，上述传感器测量、卫星测量或信号接收装置测量仅作为三种可能的预设参数测量方式的示例，UE还可以采用其他测量方式确定UE发生运动或者UE位置发生变化，本申请实施例对具体的测量方式不做具体限定。
可选的，测量方式和/或测量周期可以是由定位管理设备指示的。示例性的，第一消息还可以包括测量方式指示信息、测量周期(如每秒/每30秒/每分钟/每小时等)或第二预设时间段(如上午8：00-9：00和中午12：00-12：30等)中的一个或多个。
其中，测量方式指示信息用于指示预设参数的测量方式。示例性的，测量方式可以包括传感器测量、卫星测量或信号接收装置测量等中的一个或多个。测量周期指示信息用于指示预设参数的测量周期。
在第一消息包括测量方式和测量周期的情况下，S504包括：UE根据第一消息中包括的测量周期指示信息指示的测量周期，采用测量方式指示信息指示的测量方式，测量得到预设参数。
可选的，测量方式指示信息可以包括每一种测量方式以及每一种测量方式的状态指示信息。
其中，测量方式的状态指示信息可以包括TRUE/FALSE。一种测量方式的状态指示信息为TRUE用于指示UE可以使用该测量方式进行预设参数的测量。一种测量方式的状态指示信息为FALSE则用于指示UE不可以使用该测量方式进行预设参数的测量。例如，传感器测量方式的状态指示信息为TRUE，则用于指示UE可以使用传感器测量的方式进行预设参数(如运动参数)测量。
可选的，上述预设阈值也可以由定位管理设备指示。示例性的，第一消息还可以包括上述预设阈值。
具体的，不同的预设参数可以对应不同的预设阈值。例如，运动参数对应的预设阈值可以为大于或等于0的任何常数。接收信号参数对应的预设阈值可以为大于0的任何常数。位置参数对应的预设阈值可以为预定经纬度范围。对于预设阈值的具体设定，本申请实施例不做限定。
进一步的，第一消息还可以包括周期上报指示、预设时间段上报指示(Reportingduration)或服务小区变化触发指示(Cellchange)中的至少一个。其中，周期上报指示用于指示UE周期性上报定位参考信号的测量结果。预设时间段上报指示用于指示UE在第一预设时间段上报定位参考信号的测量结果。服务小区变化触发指示(Cellchange)用于触发UE在主服务小区发生变化时，上报定位参考信号的测量结果。UE可以根据自身的实际情况，选择合适的上报触发方式上报参考信号测量结果。例如，对于处于连接状态的UE，在确定满足运动触发条件时，可以基于运动触发条件上报参考信号测量结果；也可以周期上报、预设时间段上报或者基于服务小区变化上报。犹如，对于处于空闲状态/去激活状态的UE，为了节省电量，则可以在满足运动触发条件时，或者服务小区变化时，上报参考信号测量结果。
需要理解，本申请实施例提供的UE位置信息上报的方法可以基于长期演进定位协议(long term evolution position protocol，LPP)或者其他下NG通信系统的定位协议来进行。
其中，基于LPP的UE位置信息上报的方法中交互的信息主要可以包括(a)-(f)：
(a)请求能力(Request Capabilities)，主要用于定位管理设备(如LMF)向UE请求UE的能力信息。
其中，UE的能力信息至少用于表征UE支持的定位方式类别和/或测量定位参考信号的能力。
示例性的，UE支持的定位方式类别可以包括但不限于基于PRS的定位方式、基于SRS的定位方式、基于CSI的定位方式或基于SSB的定位方式中的一个或多个。
UE测量定位参考信号的能力可以包括但不限于UE在不同定位方式中，通过测量定位参考信号可以获取的信息类别。示例性的，UE测量定位参考信号的能力可以包括：UE可以通过测量PRS获取但不限于RSRP、RSRQ、RSTD、NRSRP或NRSRQ中的一个或多个的能力指示信息。更进一步，对于计算能力较强的UE，UE测量定位参考信号的能力可以包括：UE可以通过测量定位参考信号，计算得到初步的UE的位置信息的能力指示信息。
(b)提供能力(Provide Capabilities)，主要用于UE向定位管理设备(如LMF)提供UE的能力信息。
(c)请求辅助数据(Request Assistance Data)，主要用于UE向定位管理设备(如LMF)请求辅助信息。
其中，辅助信息可以包括但不限于邻区和参考小区的小区索引或PRS配置中的一个或多个等。示例性的，PRS配置可以包括PRS的预设测量周期、PRS的预设测量时间段等。
(d)提供辅助数据(Provide Assistance Data)，主要用于定位管理设备(如LMF)向UE提供辅助信息。
(e)请求定位信息(Request Location Information)，主要用于定位管理设备(如LMF)向UE请求位置信息。
(f)提供定位信息(Provide Location Information)，主要用于UE向定位管理设备(如LMF)提供位置信息。
因此，进一步的，如图7所示，在S501之前，本申请实施例提供的用户设备位置信息上报的方法还可以包括：
S701、UE向定位管理设备发送UE的能力信息；以及，UE从定位管理设备接收辅助信息。
可以理解，本申请实施例中，UE可以根据定位管理设备(如LMF或LMC等)的指示，在UE发生运动时，上报UE测量多个定位参考信号得到的测量结果。定位管理设备(如LMF或LMC等)可以根据UE上报的测量结果确定UE的位置。通过这样的方式，可以缓解处于空闲或去激活状态的UE为了上报参考信号的测量结果，需要周期性地进入连接状态导致的电量消耗过大，以及对链路资源浪费的问题。
为便于理解，本申请以下实施例以定位管理设备为LMF，接入和移动管理设备为AMF，接入网设备为NG-RAN，定位服务实体为5GC LCS Entities为例，介绍一种基于LPP协议的UE位置信息上报的方法。
请参考图8，图8示出了本申请实施例提供的一种UE位置信息上报的方法交互图一。如图8所示，本申请实施例提供的UE位置信息上报的方法可以包括：
S801、5GC LCS Entities向AMF发送第一位置服务请求(Location Service Request)。第一位置服务请求用于请求触发对UE定位。
其中，5GC LCS Entities可以是应用程序、客户端；也可以是其他具有定位服务业务需求的实体，例如，紧急呼叫(emergency call)等。本申请实施例对5GC LCS Entities，以及具体的定位服务业务不做具体限定。
S802、AMF向LMF发送第二位置服务请求(Location Service Request)。第二位置服务请求用于请求对UE定位。
S803、LMF向UE发送请求位置信息。请求位置信息包括运动触发条件。运动触发条件用于触发UE基于运动上报定位参考信号的测量结果。
其中，请求位置信息(RequestLocationInformation)可以包括运动触发指示(如motionTrigger或movingTrigger等)。示例性的，运动触发指示可以包括在请求位置信息(RequestLocationInformation)的请求位置CommonIEsRequestLocationInformation信元IE中。运动触发指示用于指示UE基于运动上报定位参考信号的测量结果。示例性的，运动触发指示(如motionTrigger或movingTrigger等)可以包含在请求位置信息(RequestLocationInformation)中的触发上报TriggeredReportingCriteria IE中。
进一步的，请求位置信息(RequestLocationInformation)还可以包括周期上报指示、预设时间段上报指示(ReportingDuration)或服务小区变化触发指示(Cellchange)中的至少一个。其中，周期上报指示用于指示UE周期性上报定位参考信号的测量结果。预设时间段上报指示用于指示UE在第一预设时间段上报定位参考信号的测量结果。 服务小区变化触发指示(Cellchange)用于触发UE在主服务小区发生变化时，上报定位参考信号的测量结果。
示例性的，请求位置信息(RequestLocationInformation)可以包括以下内容：
CommonIEsRequestLocationInformation::＝SEQUENCE{
locationInformationType LocationInformationType,
triggeredReporting TriggeredReportingCriteria OPTIONAL,
--Cond ECID
...
}
TriggeredReportingCriteria::＝SEQUENCE{
cellChange BOOLEAN,
reportingDuration ReportingDuration,
motionTrigger BOOLEAN,
...
}
需要说明的时，以上运动触发指示(如motionTrigger)在请求位置信息(RequestLocationInformation)中的存在形式仅作为一种示例，本申请实施例对此不做限定。例如，运动触发指示(如motionTrigger)还可以以其他形式包含在请求位置信息(RequestLocationInformation)中，或者运动触发指示还可以以其他名称包含在请求位置信息(RequestLocationInformation)中。
S804、NG-RAN释放与UE之间的RRC连接。
在一种情况下，在NG-RAN释放与UE之间的RRC连接之后，UE进入去激活状态。
在另一种情况下，如图8中的步骤S804＇所示，在G-RAN释放与UE之间的RRC连接之后，NG-RAN还可能释放UE的上下文。在这种情况下，UE会进入空闲状态。
关于NG-RAN释放与UE之间的RRC连接，以及NG-RAN释放UE的上下文的具体过程，可以参考常规技术中的介绍和说明，这里不做赘述。
S805、UE确定预设参数的变化值大于预设阈值。
其中，预设阈值可以为0，也可以为任何大于0的常数。也就是说，本申请实施例中UE上报参考信号的测量结果可以是基于UE发生运动，也可以是基于UE运动超出一定范围等触发的。
S806、UE测量定位参考信号，得到定位参考信号的测量结果。
其中，定位参考信号可以包括但不限于：PRS、SRS、CSI或SSB中的一种或多种。定位参考信号的测量结果可以包括但不限于：RSRP、RSRQ、RSTD、NRSRP或NRSRQ)中的一个或多个。
需要说明的是，步骤S806可以在步骤S805之后执行，在这种情况下，UE可以根据来自LMF的请求位置信息(RequestLocationInformation)，在确定预设参数的变化值大于预设阈值时触发对定位参考信号的测量。
另外，可选的，在本申请实施例中，在步骤S804之前，UE也可以测量定位参考 信号，得到定位参考信号的测量结果，如图8所示。具体的，UE可以按照预设测量周期周期性测量定位参考信号，得到定位参考信号的测量结果。或者UE也可以在预设时间段内测量定位参考信号，得到定位参考信号的测量结果。或者按照其他规则定位参考信号的测量，本申请实施例对此不做限定。
S807、UE进入连接状态。
在一种情况下，若UE在执行步骤S807前处于去激活状态，由于在去激活状态下NG-RAN会储存UE的上下文，因此，UE可以快速恢复与NG-RAN之间的RRC连接，进入连接状态。
在另一种情况下，若UE在执行步骤S807前处于空闲状态，则UE需要重新建立与NG-RAN之间的RRC连接。以及，NG-RAN需要与AMF建立连接。之后，UE进入连接状态。
关于UE从去激活状态或空闲状态进入连接状态的过程，可以参考常规技术中的介绍和说明，这里不做赘述。
S808、UE向LMF上报位置信息。位置信息包括定位参考信号的测量结果。
示例性的，UE可以通过LPP消息中的提供位置信息(ProvideLocationInformation)向LMF上报位置信息。
其中，UE向LMF上报的定位参考信号的测量结果可以包括：UE在步骤S806测量定位参考信号得到的定位参考信号的测量结果；和/或UE在步骤S804之前测量定位参考信号得到的定位参考信号的测量结果。
也就是说，若UE在步骤S804之前未对定位参考信号进行测量，则UE在步骤S808向LMF上报的位置信息仅包括UE在S806测量定位参考信号得到的定位参考信号的测量结果。
若UE在步骤S804之前测量定位参考信号得到了定位参考信号的测量结果，那么UE可以不执行步骤S806，在这种情况下，UE在步骤S808向LMF上报的位置信息仅包括UE在步骤S804之前测量定位参考信号得到的定位参考信号的测量结果。或者，UE也可以执行步骤S806，在这种情况下，UE在步骤S808向LMF上报的位置信息既包括UE在步骤S806测量定位参考信号得到的定位参考信号的测量结果，也包括UE在步骤S804之前测量定位参考信号得到的定位参考信号的测量结果。
其中，若UE向LMF上报的定位参考信号的测量结果包括：UE在步骤S806测量定位参考信号，得到的定位参考信号的测量结果；和UE在步骤S804之前测量(如周期性测量、预设时间段内测量)定位参考信号，得到的定位参考信号的测量结果，则LMF可以根据不同时刻的测量结果绘制UE的移动轨迹。其中，绘制UE的移动轨迹可以用于一些特殊的应用场景，如旅行类客户端中，为用户绘制旅程记录等。
可选的，UE还可以在空闲状态或去激活状态下向LMF上报位置信息。如图9所示，UE还可以在执行完步骤S805，且得到定位参考信号的测量结果之后，不执行步骤S807，直接执行步骤S808。具体的，UE可以通过EDT或者空闲状态或去激活状态下的预配置资源等早期数据传输方式上报定位参考信号的测量结果。
S809、LMF根据定位参考信号的测量结果获取对UE的定位结果。
S810、LMF向AMF发送第一位置服务响应(Location Service Response)。
其中，第一位置服务响应包括LMF对UE的定位结果。
S811、AMF向5GC LCS Entities发送第二位置服务响应(Location Service Response)。
其中，第二位置服务响应包括LMF对UE的定位结果。
进一步的，在执行S801之前，UE还可以与LMF交互UE的能力信息和辅助信息。具体的，如图8和图9所示，本申请实施例提供的UE位置信息上报的方法还包括：
S800-1、LMF向UE发送请求能力(Request Capabilities)信息，用于请求UE的能力信息。
其中，UE的能力信息至少用于表征UE支持的定位方式类别和/或测量定位参考信号的能力。
示例性的，UE支持的定位方式类别可以包括但不限于基于PRS的定位方式、基于SRS的定位方式、基于CSI的定位方式或基于SSB的定位方式中的一个或多个。
UE测量定位参考信号的能力可以包括但不限于UE在不同定位方式中，通过测量定位参考信号可以获取的信息类别。示例性的，UE测量定位参考信号的能力可以包括：UE可以通过测量PRS获取但不限于RSRP、RSRQ、RSTD、NRSRP或NRSRQ中的一个或多个的能力指示信息。更进一步，对于计算能力较强的UE，UE测量定位参考信号的能力可以包括：UE可以通过测量定位参考信号，计算得到初步的UE的位置信息的能力指示信息。
S800-2、UE向LMF发送提供能力(Provide Capabilities)信息，提供能力信息包括UE的能力信息。
S800-3、UE向LMF发送请求辅助数据(Request Assistance Data)信息，用于请求辅助信息。
其中，辅助信息可以包括但不限于邻区和参考小区的小区索引或PRS配置中的一个或多个等。示例性的，PRS配置可以包括PRS的预设测量周期、PRS的预设时间段等。
S800-4、LMF向UE发送提供辅助数据(Provide Assistance Data)信息，提供辅助数据信息包括辅助信息。
需要说明的是，上述图8和图9是以5GC LCS Entities触发对UE定位作为示例介绍本申请实施例提供的UE位置信息上报的方法。事实上，对UE定位还可以由AMF触发，或者还可以由LMF触发。
其中，若对UE定位由AMF触发，与对UE定位由5GC LCS Entities触发的不同之处在于，LMF根据AMF触发的第一位置服务请求(location service requestf)向UE发送请求位置信息。且在AMF从LMF处收到LMF根据UE上报的定位参考信号的测量结果，获取对UE的定位结果之后，无需向5GC LCS Entities发送响应消息。
具体的，若对UE定位由AMF触发，UE可以由去激活状态或空闲状态进入连接状态后上报位置信息。如图10所示，本申请实施例提供的UE位置信息上报的方法可以包括：

第四阶段：位置信息上报及位置服务响应阶段。具体的，第四阶段包括步骤S808、S809和S810。
若对UE定位由LMF触发，与对UE定位由AMF触发的不同之处在于，LMF自主触发向UE发送请求位置信息。且在LMF根据UE上报的定位参考信号的测量结果获取对UE的定位结果之后，无需向AMF发送响应消息。
具体的，若对UE定位由LMF触发，UE可以由去激活状态或空闲状态进入连接状态后上报位置信息。如图12所示，本申请实施例提供的UE位置信息上报的方法可以包括：
第一阶段：交互UE的能力信息和辅助信息。具体的，第一阶段包括步骤S800-1、S800-2、S800-3和S800-4。

或者，若对UE定位由LMF触发，UE也可以在去激活状态或空闲状态下上报位置信息。如图13所示，本申请实施例提供的UE位置信息上报的方法可以包括：
第一阶段：交互UE的能力信息和辅助信息。具体的，第一阶段包括S800-1、S800-2、S800-3和S800-4。
第二阶段：发送请求位置信息(如motionTrigger或movingTrigger)。具体的，第二阶段包括S803。
第三阶段：释放RRC连接后确定是否上报阶段。具体的，第三阶段包括S804(S804， 或者S804和S804′)、S805、S806。
