本申请基于申请号为201710313214.8、申请日为2017年05月05日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及通讯领域，特别是涉及定位辅助数据配置方法、装置、设备、系统及存储介质。
背景技术
长期演进(LTE，Long Term Evolution)是由第三代合作伙伴计划(3GPP，The 3rd Generation Partnership Project)组织制定的通用移动通信系统(UMTS，Universal Mobile Telecommunications System)技术标准的长期演进，于2004年12月在3GPP多伦多会议上正式立项并启动。LTE系统增加了频谱效率和数据传输速率(20M带宽2*2MIMO在64QAM情况下，理论下行最大传输速率为201Mbps，除去信令开销后大概为150Mbps，但根据实际组网以及终端能力限制，一般认为下行峰值速率为100Mbps，上行为50Mbps)。
5GNR(基于正交频分复用(OFDM，Orthogonal Frequency Division Multiplexing)的全新孔口设计的全球性5G标准)，也是下一代非常重要的蜂窝移动技术基础。5GNR网络主要有三大特点：极高的速率(eMBB，enhanced mobile broadband)，极大的容量(mMTC，Massive Machine Type Communication)，极低的时延(URLLC，Ultra Reliable Low Latency Communications)。
定位业务(LCS，LoCation Service)是移动通信网所提供的一种新型增值业务。该业务通过无线定位技术来获得终端的位置信息(经纬度、移动速度等)，提供给终端、移动通讯网络或者其它外部实体，实现各种与位置相关的业务。目前LTE长期演进技术中包含以下定位技术：观测到到时间差(OTDOA，Observed Time Difference of Arrival)、上行到到时间差(UTDOA，Uplink Time Difference of Arrival)、辅助全球卫星定位系统(AGPS，Assisted Global Positioning System)等方法。5GNR系统会沿用这些技术。
上述的OTDOA、AGPS包含两种定位模式：基于用户设备(UE，User Equipment)定位模式(UE-based，Network-assisted)和基于网络(Network-based，UE-assisted)的。上述两种方式的根本区别在于：在哪个节点(UE或E-SMLC(Evolved Serving Mobile Location Center))进行位置解算。基于UE的定位模式，UE执行相关测量，并结合网络侧辅助数据解算UE位置；基于网络的定位模式UE执行定位测量和上报过程，在网络侧解算UE位置，如现有LTE架构中的OTDOA定位方法。基于网络的模式，定位终端的容量受限于需要上报RSRP；定位的实时性受限于信息交互。相对而言，基于UE定位模式(UE-based)，由于不需要上报测量值和减少的信息交互流程，有更大的网络容量和更好的实时性，更适合大容量和低时延的LTE和5G NR。
然而，相关技术中对于如何更新和配置基于UE定位模式的OTDOA定位模式的辅助数据还没有任何记载和说明。
发明内容
有鉴于此，本发明实施例期望提供一种定位辅助数据配置方法、装置、设备、系统及存储介质，能够更新和配置OTDOA定位模式的辅助数据。

第二方面，本发明实施例还提供一种定位辅助数据配置方法，包括：UE接收来自E-SMLC的OTDOA定位辅助数据；所述UE根据所述定位辅助数据进行参考小区选择和邻近小区列表排序。

第八方面，本发明实施例还提供一种计算机存储介质，存储有计算机程序，所述程序被处理器执行时实现任一定位辅助数据配置方法。
第九方面，本发明实施例还提供一种定位辅助数据配置装置，包括：
存储器，配置为存储定位辅助数据配置的程序；
处理器，配置为运行所述程序，其中，所述程序运行时执行上述的定位辅助数据配置方法。

应用本实施例具有以下有益技术效果：
1、由于无论哪种下行定位，其测量都在UE测，与相关技术中的OTDOA等技术在网络侧进行定位和定位辅助数据处理相比，不需上报测量结果，减少传输量。
2、与相关技术中的OTDOA等技术在网络侧对定位辅助数据选取参考小区和排序邻近列表相比，本发明实施例更方便于结合各种先验信息，进行参考小区选取和邻近列表排序，从而取得更好的定位效果。比如，原有网络侧的参考小区选取只能通过UE上传的测量信息和位置信息进行选择，受限于上报粒度和上报量的限制；而本发明支持在UE侧进行参考小区选择，更方便利用手机的传感器、地图信息和测量信息，能更好的选取参考小区，由附图7可见更好的参考小区选择可以获得更优的定位测量。
3、与相关技术中的OTDOA等技术在网络侧传递的定位辅助数据相比，增加了差量传递，当更新的小区定位辅助不变时，只传输(全球小区识别码)GCI；小区信息部分变更时，只发送变更信息。
下面结合附图和实例对上述过程进行详细说明。
