Description

一种实现定位测量的方法、 系统及装置 本申谛要求在 2009年 10月 29日提交中国专利局、 申请号为 200910235920.0、发明名称为"一种实现定位测量的方法、 系统及装置"的中国 专利申谛的优先权, 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, 特别是指一种实现定位测量的方法、 系统及 装置。 背景拭术
参见图 1所示, 与演进通用陆地无线接入网络(UMTS Terrestrial Radio Access Network, E-UTRAN )相关的定位架构主要包括演进的服务移动位置 中心(Evolved Serving Mobile Location Center, E-SMLC )> 移动性管理实体 ( Mobility Management Entity, MME )> 基站(eNB ) 以及用户设备(UE )。
移动定位业务是利用 UE的位置开展的业务, 比如紧急救援等。 当前, 定 位可以有如下两种实现方法: 控制面定位和用户面定位(Secure User-Plane Location )。 控制面定位是指定位过程需要使用 E-UTRAN的信令链路, MME 向 E-SMLC发送定位谛求触发定位过程, 完成定位操作后 E-SMLC向 MME 返回定位结果, E-SMLC、 MME> eNB> UE等都可能参与到定位过程中。
E-SMLC用于将客户端谛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; 对返回的位置估计结果计算最终结果和精度。 MME为 定位业务(Location Service, LCS )提供移动性管理功能, 这包括向 E-SMLC/ 网关移动位置中心( Gateway Mobile Location Center, GMLC )通才艮 UE的移 动。 eNB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向 E-SMLC提供定位服务相关的测量结果。
在目前的长期演进(Long Term Evolution, LTE ) 系统中, 基于控制面的 定位方法包括: 小区标识(CELL ID ) +时间提前量(Timing Advance, TA ) + 信号到达方向角 (Angle Of Arrive, AOA )方案, 实测到达时间差(Observed Time Difference Of Arrival, OTDOA )方案,即:增强的蜂窝小区识别(Enhanced Cell Identify, E-CID )方式, 以及增强的全球导航定位系统( Requirements for Support of Assisted Global Navigation Satellite System, A-GNSS )方式。
CELL ID+TA+AOA方案的基本原理为: 获得终端到基站与正北方向的夹 角 (即 AOA ) 以及终端的 TA来进行位置的计算。 在 LTE中, TA的获得可 以是通过终端维护, 也可以通过基站测量获得。
eNB通过智能天线得到 UE发射信号的 AOA, UE处于以 eNB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。
参见图 2所示, 定时提前(NTA, Timing Advance )指的是 UE侧, 上下 行帧定时之间的偏移量,
参见图 3所示, 考虑到基站侧的定时, 可以认为在通常情况下, NTA总是 体现距离 d导致的两倍时延。
根据 NTA可以推算出 UE同 eNB之间的距离, UE就处于以 eNB为圆心、 距离为半径的圓周上。 E-SMLC根据以上的信息和服务小区的地理位置信息, 就可以计算出 UE的位置,
发明人研究过程中, 针对 TA上报定义了两种格式类型: 类型 1 ( Typel ) 和类型 2 ( Ί ρβ2 ), TADV表示上报的时间提前信息。
Typel: TADV = (eNB Rx - Tx time difference) + (UE Rx - Tx time difference);
Type2: TADV = eNB Rx - Tx time difference;
其中, UE Rx - Tx time difference为终端收发时间差, eNB Rx - Tx time difference为基站收发时间差。
但是, 目前的 CELL ID+TA+AOA定位方案中, eNB不知怎样选择合适的 TA格式, 因此需要引入一种机制来确保 eNB上报时间提前量。 明内容

参见图 4所示, 本发明实施例实现定位测量的方法包括以下步骤: 步骤 401: 在进行终端 E-CID定位过程中, 利用获得的终端是否支持收 发时间差测量的倌息, 以及基站是否支持基站收发时间差测量与终端收发时 间差测量的合并的信息, 确定时间提前量上报格式,
步骤 401具体可以这样实现: E-SMLC接收到来自移动性管理实体的位 置业务谛求消息, 从终端获取该终端是否支持终端收发时间差测量的信息, 的合并的信息; 如果 E-SMLC确定采用 E-CID方式, 根据该终端是否支持终

步骤 607: 在向 E-SMLC返回的响应消息中携带定位测量结果。
步骤 608: E-SMLC 收到该响应消息后, 向 MME返回位置业务响应 ( Location Service Response ) 消息,
参见图 7所示, 本发明实现定位测量的实施例三具体过程如下: 步骤 701: E-SMLC接收到来自 MME的 Location Service Request消息, 消息中携带 QOS等;
步骤 702: E-SMLC收到该消息后,根据存储的信息决定采用合适的定位 方法, 这里, 存储的信息可以包括 UE的能力信息和 /或基站的能力信息, 如 果采用 E-CID方式, 可以根据 QOS需求决定可采用的 TA上报格式。 步骤 703: E-SMLC发送位置倚求消息( Request Location information ), 以发起针对 UE的 E-CID定位测量, 谛求消息中指明 eNB可采用的 TA上报 格式。
