Description

用户设备的定位方法及装置、存储介质和电子装置
本申请要求在2018年09月14日提交中国专利局、申请号为201811076343.0的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及通信领域，具体而言，涉及一种用户设备的定位方法及装置、存储介质和电子装置。
背景技术
第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)自release 9开始引入对定位服务的支持，如今定位服务已经成为无线通讯网络中一种重要的增值服务。
小区标识(Cell Identity，Cell ID)和增强型小区标识(Enhanced Cell Identity，E-CID)是通讯网络中非常重要的定位方法。基本原理是利用服务小区的地理坐标估计用户设备(User Equipment，UE)的位置。E-CID使用一些附加的测量信息来进行定位，这些测量信息通常还有其他功能，但是通常不会单独为了定位进行测量。
第五代移动通信系统(5th generation mobile networks，5G)为了实现更快的数据传输速率，选择使用毫米波技术。
毫米波是指波长在毫米数量级的电磁波，毫米波频率大约在30GHz～300GHz之间。毫米波频段的一个特性是在空气中衰减严重，绕射能力弱，大气和雨水吸收影响较大。为了克服这些影响传播的因素，大阵列和窄波束被作为数据传输的一种重要技术。相关技术中的5G标准中已经确定支持毫米波段以窄波束轮询的方式发送同步信号/物理广播信道块(Synchronization Signal/Physical Broadcast Channel block，SS/PBCH block)来实现同步等功能。波束轮询的方式在一定程度上可以避免不同小区发射的同步信号块(Synchronization Signal Block，SSB)互相干扰。5G标准中还没有设计以5G信号测量为基础的定位方法。

存储器104可用于存储计算机程序，例如，应用软件的软件程序以及模块，如本发明实施例中的UE的定位方法对应的计算机程序，处理器102通过运行存储在存储器104内的计算机程序，从而执行多种功能应用以及数据处理，即实现上述的方法。存储器104可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器104可进一步包括相对于处理器102远程设置的存储器，这些远程存储器可以通过网络连接至移动终端10。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置106用于经由一个网络接收或者发送数据。上述的网络具体实例可包括移动终端10的通信供应商提供的无线网络。在一个实例中，传输装置106包括一个网络适配器(Network Interface Controller，NIC)，其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个实例中，传输装置106可以为射频(Radio Frequency，RF)模块，其用于通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于上述移动终端的UE的定位方法，图2是根据本发明实施例的一种UE的定位方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，在发起的定位请求后，UE接收定位管理单元(Location Management Function，LMF)发送的第一辅助信息；其中，所述第一辅助信息至少包括：由下一代无线接入网络(The Next Generation Radio Access Network，NG-RAN)节点向所述LMF上报的指定小区的同步信号块(Synchronization Signal Block，SSB)波束轮询信息。
步骤S204，所述UE对所述指定小区进行测量，并获取第一测量信息。
步骤S206，根据所述第一测量信息和第一辅助信息，所述UE确定该UE的位置。
通过本公开，通过利用UE测量的小区的测量信息以及由NG-RAN节点提供的小区的SSB波束轮询信息，同时，可以应用在网络中的多个网元或者设备上，因此，可以解决相关技术中无法基于5G信号对UE所在位置进行测量的问题，达到了在不增加资源开下的前提下实现了对设备定位，同时还能够提高定 位精度的效果。
可选地，在该SSB波束轮询信息至少包括：发送SSB的子载波间隔和循环前缀配置，SSB波束数量，所述指定小区的全部SSB索引以及SSB波束在地理坐标系中的覆盖角度。

可选地，在所述UE接收所述LMF发送的所述第一辅助信息之前，所述UE向所述LMF发送用于请求所述第一辅助信息的辅助信息请求消息。
需要说明的是，如果UE没有请求或者UE处于“忙”的状态等原因导致UE无法主动请求获取第一辅助信息的话，LMF可以自行向UE发送第一辅助信息。
具体而言，LMF可以通过判断是否与UE预先确定的UE请求时间超时，并在判断结果为是的情况下，自行向UE发送第一辅助信息。
具体而言，LMF还可以通过向UE发送询问指令，并根据UE响应的询问结果，确定是否向UE发送第一辅助信息。
需要说明的是，其他基于本实施例思路的，能够实现LMF向UE主动发送第一辅助信息的方式，均在本实施例的保护范围之内。
可选地，所述指定小区至少包括以下其中之一：所述UE所在的服务小区，以及所述UE所在的服务小区的相邻小区。
具体而言，如果UE经过测量只获取到服务小区对应的第一测量信息的话，那么本实施例主要是针对UE所在的服务小区下对UE的定位，即单小区SSB定位。而如果UE经过测量还获取到相邻小区对应的第一测量信息的话，那么本实施例中所应用的方案是针对在多个小区下对UE的定位，即多小区SSB定位。再而，如果UE经过测量只获取到相邻小区对应的第一测量信息的话，那么本实 施例主要是针对的是UE所在的服务小区的相邻小区下对UE的定位。故而，根据实际的使用需求，UE可以使用不同的测量策略，分别对位于不同小区进行测量，以获取不同的第一测量信息。从而实现了对不同小区下对UE的定位。
可选地，所述第一辅助信息还至少包括以下其中之一：所述服务小区的地理坐标，以及所述相邻小区的地理坐标。

可选地，如果UE测量到的测量结果超出所述指定小区中的任意一个SSB时，UE选择所述指定小区中强度最高或者强度大于强度阈值的SSB作为第一测量信息中的所述指定小区的SSB索引。
具体而言，UE根据所搜索到的指定小区的SSB索引和第一辅助信息中的其他信息，还有SSB波束在地理坐标系中覆盖的位置的重叠范围估计UE位置。
具体地，UE可以使用SSB中主同步信号(Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)，物理广播信道(Physical Broadcast Channel，PBCH)和PBCH的解调参考信号(Demodulation Reference Signal，DMRS)全部或者其中某些信号的RSRP和RSRQ来更精确地估算UE位置。

可选地，所述指定小区至少包括以下其中之一：所述UE所在的服务小区，以及所述UE所在的服务小区的相邻小区。
具体而言，如果UE经过测量只获取到服务小区对应的第二测量信息的话，那么本实施例主要是针对UE所在的服务小区下对UE的定位，即单小区SSB定位。而如果UE经过测量还获取到相邻小区对应的第二测量信息的话，那么本实施例中所应用的方案是针对在多个小区下对UE的定位，即多小区SSB定位。再而，如果UE经过测量只获取到相邻小区对应的第二测量信息的话，那么本实施例主要是针对的是UE所在的服务小区的相邻小区下对UE的定位。故而，根据实际的使用需求，UE可以使用不同的测量策略，分别对不同小区进行测量，以获取不同的第二测量信息。从而实现了对不同小区下对UE的定位。
可选地，所述LMF从所述UE和/或NG-RAN节点获取所述第二测量消息。
可选地，LMF至少通过如下两种方式之一获取所述第二测量消息。
方式一：所述LMF向所述UE发送第二辅助信息，其中，所述第二辅助信息用于所述UE对所述服务小区和所述相邻小区的SSB进行测量；所述LMF接收所述UE发送的所述第二测量消息。

具体而言，在UE对所述相邻小区的SSB进行盲检时，UE可以在发送的第三辅助信息中携带用于盲检对应的检测规则，以防止LMF无法识别检测结果。
具体地，UE对所述相邻小区的SSB进行检测盲检的规则还可以是LMF与UE在定位之前交互确定的检测规则。
可选地，如果UE测量到的测量结果超出所述指定小区中的任意一个SSB时，UE选择所述指定小区中强度最高或者强度大于强度阈值的SSB作为第二测量信息中的所述指定小区的SSB索引。
可选地，所述第二测量消息包括以下其中之一：所述指定小区的小区标识信息，所述指定小区的SSB索引，以及SSB中一个或者多个信号的RSRP和RSRQ。
实施例3

为了更好的理解上述实施例中提供的方案，还提供了如下的场景1对上述实施例进行更详尽的说明：
场景1：
基于单小区，通过UE对UE进行定位。图5是根据本发明实施例的一种基于场景1的UE的定位的流程图，如图5所示：
步骤1：NG-RAN node将自身的SSB轮询配置信息发送给LMF。具体地，子载波间隔为120KHz，常规CP，SSB发送周期为5ms，全部SSB索引k 1-k 8，发送k ssb个SSB波束
步骤2：UE发起定位请求。
步骤3：UE通过LPP或者NRPP消息向LMF发送请求第一辅助信息的请求。
步骤:4：LMF通过LPP或者NRPP消息携带的第一辅助信息将SSB轮询配置信息发送给UE。
步骤5：UE在接收到第一辅助消息后，对该UE所在的服务小区的SSB波束进行测量，获取到包括了SSB index为k 3，测得PSS接收能量和接收质量分别为RSRP 1和RSRQ 1的第一测量信息。
步骤6：UE根据SSB轮询配置信息和第一测量信息对该UE的定位结果进行估计。
图6是根据本发明实施例的一种基于SSB波束对UE进行定位的示意图。UE根据SSB轮询配置信息确定了如图6所示的在当前的服务小区中包括了k 1-k 8一共8个SSB波束。UE根据在步骤4中生成的第一测量信息中的SSB index，从而能够确定UE定位于对应编号为k 3的SSB波束上。同时，根据第一测量信息中的RSRP 1和RSRQ 1(图6中通过圆型范围示出)，UE可以在SSB波束上能够对UE进行更加精确地定位。
场景2：
基于单小区，通过LMF对UE进行定位。图7是根据本发明实施例的一种基于场景2的UE的定位的流程图，如图7所示：
步骤1：NG-RAN node将自身的SSB轮询配置信息发送给LMF。具体地，子载波间隔为120KHz，常规循环前缀(Cyclic Prefix，CP)，SSB发送周期为5ms，全部SSB索引k 1-k 8，发送k ssb个SSB波束。
步骤2：NG-RAN node向UE发起定位请求。
步骤3：UE对cell 1进行测量，获取到的cell 1的第二测量结果至少包括： 定位能力支持使用multi-beam SSB信息的E-CID定位，t 1时刻，UE测量服务小区cell 1的SSB波束，SSB index k 3。
步骤4：UE对cell 2进行测量，获取到的cell 2的第二测量结果至少包括：定位能力支持使用multi-beam SSB信息的E-CID定位，t 2时刻，UE测量服务小区cell 2的SSB波束，SSB index k 5。
步骤5：UE通过LPP或者NRPP消息将cell 1和cell 2的第二测量信息发送至LMF。
步骤6：LMF根据SSB轮询配置信息和cell 1以及cell 2的第二测量信息对该UE的定位结果进行估计。
图8是根据本发明实施例的另一种基于SSB波束对UE进行定位的示意图。UE根据SSB轮询配置信息确定了如图8所示的在cell 1和cell 2中包括了当前的服务小区中包括了k 1-k 8一共8个SSB波束。UE基于在步骤3中生成的cell 1的第二测量信息中的SSB index k 3以及步骤4中生成的cell 2的第二测量信息中的SSB index k 5，从而能够确定UE定位于cell 1对应编号为k 3的SSB波束和cell 2对应编号为k5的SSB波束的交集(图8中的圆形部分)之上。
图9是根据本发明实施例的再一种基于SSB波束对UE进行定位的示意图。UE根据SSB轮询配置信息确定了如图9所示的在cell 1和cell 2中包括了当前的服务小区中包括了k 1-k 8一共8个SSB波束。如果在cell 1和cell 2的第二测量信息中均设置了如场景1中第一测量消息中的PSS接收能量和接收质量分别为RSRP 1和RSRQ 1的情况下，根据RSRP 1和RSRQ 1(图9中矩形部分)，UE可以在cell 1和cell 2的SSB波束上能够对UE进行更加精确地定位。
场景3：
基于单小区，通过NG-RAN node对UE进行定位。图10是根据本发明实施例的一种基于场景3的UE的定位的流程图，如图10所示：
步骤1：NG-RAN node向UE发起定位请求。
步骤2：UE对该UE所在的服务小区的SSB波束进行测量，获取到包括了SSB index为k 3，测得PSS接收能量和接收质量分别为RSRP 1和RSRQ1的第三测量信息。
步骤3：UE通过preamble向NG-RAN node发送携带有SSB index为k 3，测得PSS接收能量和接收质量分别为RSRP 1和RSRQ 1的第三测量信息。
步骤4：NG-RAN node根据自身具备的SSB轮询配置信息(即子载波间隔为120KHz，常规CP，SSB发送周期为5ms，所述指定小区的全部SSB索引k 1-k 8， 发送k ssb个SSB波束)、自身地理位置和第三测量信息对该UE的定位结果进行估计。
