Description

一种小区位置信息获取方法、 系统及装置 本申请要求于 2009 年 9 月 29 日提交中国专利局, 申请号为 200910093366.7,发明名称为 "一种小区位置信息获取方法、系统及装置" 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
本发明涉及通信技术领域, 特别涉及一种小区位置信息获取方法、 系统及装置。 背景技术
移动定位业务是利用 UE ( User Equipment, 用户设备) 的位置开展 的业务, 比如紧急 1援等。 当前, 定位包括以下两种实现方法: 控制面 定位和 SUPL ( Secure User-Plane Location, 用户面定位) 。 控制面定位 是指定位过程需要使用 E-UTRAN ( Evolved Universal Terrestrial Radio Access Network , 演进的通用陆基无线接入网) 的信令链路, MME ( Mobility Management Entity, 移动性管理实体) 向 E-SMLC ( Evolved Serving Mobile Location Center, 演进的服务移动位置中心 )发送定位请 求触发定位过程, 完成定位操作后 E-SMLC 向 MME返回定位结果, E-SMLC、 MME、 eNodeB, UE等都可能参与到定位过程中。
与 E-UTRAN相关的定位架构如图 1所示,包括: E-SMLC、SLP( SUPL Location Platform , SUPL定位平台 ) 、 MME、 eNodeB, UE。 其中,
E-SMLC, 用于将用户请求的位置要求转化为相应的 E-UTRAN测量 参数, 并选择定位方法; 对返回的位置计算最终结果和精度。
MME, 用于为 LCS ( Location Service, 定位服务)业务提供移动性 管理功能, 包括向 E-SMLC/GMLC ( Gateway Mobile Location Center, 网 关移动位置中心)通报 UE的移动等。
eNodeB, 用于向 E-SMLC提供定位服务相关的测量结果, 以及传递 定位服务所需的辅助信息等。 UE, 用于向 E-SMLC提供定位服务相关的测量结果。
在目前的 LTE ( Long Term Evolution, 长期演进 )系统中, 基于控制 面的定位方法包括: CELL ID (小区标识 ) +TA ( Timing Advance , 时间 提前量) +ΑΟΑ ( Angle of Arrival, 信号到达方向角) 方案, OTDOA ( Observed Time Difference Of Arrival, 可观察到达时间差分), A-GNSS ( Advance Gateway Navigation Satellite System, 先进全球导航卫星系统) 等, 为了正确计算 UE的位置, 这些方案都需要获取小区天线位置信息。
其中, CELL ID+TA+AOA 方案的基本原理为, 通过获得 UE 到 进行位置的计算。 在 LTE中, TA可以由 UE维护, 也可以通过基站测量 获得。
eNodeB通过智能天线得到 UE发射信号的 AOA, UE处于以 eNode B 为起点的射线上, 且射线从正北方向逆时针旋转的角度为 AOA。
UE侧的定时如图 2所示, 上行无线帧与下行无线帧之间的定时偏移 量为 NTA。
基站侧的定时如图 3所示, 可以认为在通常情况下, ΝΤΑ总是体现距 离 d导致的两倍时延。 根据 NTA可以推算出 UE同 eNode B之间的距离, 如图 4所示, UE处于以 eNode B为圆心、距离为半径的圆周上。 E-SMLC 根据以上的信息, 和服务小区位置信息, 就可以计算出 UE的位置。
但目前的 CELL ID+TA+AOA定位方案中缺少获取服务小区位置信 息的方法, 进而也无法根据服务小区位置信息计算 UE的位置。 发明内容
