Description

对用户 i殳备进行定位的方法和装置 本申请要求于 2011 年 11 月 29 日提交中国专利局、 申请号为 201110399659.5、发明名称为"对用户设备进行定位的方法和装置 "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
本发明涉及无线通信***,具体涉及对用户设备(UE, User Equipment ) 进行定位的方法和装置。 技术背景
定位技术是为了确定 UE的地理位置而采用的技术,可以利用无线通信 网络的资源来直接或者间接地得到 UE的位置信息。第三代合作伙伴项目长 期演进 ( 3GPP LTE , Third Generation Partnership Project Long Term Evolution ) 中采用的标准用户设备定位方式有三种: 网络辅助的全球导航 卫星*** (GNSS , Global Navigation Satellite System)定位、 观察到达时间差 ( OTDOA, Observed Time Difference Of Arrival )定位、 以及增强型小区标 识(e-CID, Enhanced Cell Identification )定位。
LTE的 UE定位算法一般可以通过检测 UE和基站之间无线电波传播信 号的特征参数 (如: 信号场强、 传播信号到达时间差、 信号到达方向角等), 再根据有关的定位算法来估计 UE的位置。 GNSS的定位方法要求 UE具有 接收 GNSS信号的无线接收器, GNSS的具体实现包含全球定位***( GPS, Global Positioning System ) 定位、 伽利略 ( Galileo )定位等等。 OTDOA和 e-CID的定位都是网络定位的类型,主要依靠对移动通信***内部的无线资 源特征参数进行检测, 再根据定位算法来估计 UE位置。 OTDOA定位利用 UE接收来自多个基站的下行定位参考信号 (PRS , Positioning Reference Signal )并进行定时测量, 并上报基站间的 PRS到达时间差, 在网络定位服 务器上计算得到 UE的地理位置。 OTDOA在进行测量之前需要进行基站之 间的同步过程。
e-CID 定位是在蜂窝移动通信中易于实现的定位方式。 在小区标识 ( CID, Cell Identification )定位中, 每个小区都有自己特定的小区标识 (ID, Identification), 当进入某一小区时, UE要在当前服务小区进行注册, *** 的数据中就会有相应的小区 ID。***根据采集到的 UE所处小区的 ID来确 定 UE的位置。 在 e-CID定位中, UE当前的服务小区获取 UE的往返时间 ( RTT, Round Trip Time )或者说是时间提前量(TA, Timing Advance ), 到达角 (AOA, Angle of Arrival)等信息进一步提高定位精度。 如图 1所示, 当服务小区获得 UE的 RTT后可以计算出服务基站与 UE之间的距离, 进 一步利用服务基站与 UE之间的 AoA以及服务基站的位置可以确定 UE的 位置。
如上所述, e-CID定位技术在 CID的基础上增加了 AoA估计和 RTT估 计, 因此在 CID的基础上提高了定位精度。 但是, 服务基站获取 AoA信息 的首要条件是基站需装设阵列智能天线, 并且对智能天线的要求较高。 所 以 e-CID定位方法如果没有 AoA的值仅凭 RTT信息只能获取 UE距离基站 的距离 S, 即在 CID定位的基础上进一步限定 UE在以当前基站为圆心、半 径为 S的圆或弧上, 不能进行准确定位估计。 另外, 由于仅由一个服务基 站测量距离 RTT和 AoA, 因此当智能天线的精度低或者当通信环境发生变 化时, 也会影响定位的准确性。
因此, 本领域中存在进一步改进 e-CID定位的需求。 发明内容

下文中详细描述本发明实施例提供的帮助改进定位的方法。
图 2示出了 e-CID定位技术中所采用的 RTT估计。如图所示, UE和其 月良务基站(例如演进节点 B, eNB, e-NodeB )是同步的。 UE Tx表示 UE 发送上行参考信号的时刻, eNB Rx表示该上行参考信号到达服务 eNB的时 刻; eNB Tx表示 eNB发送下行参考信号的时刻, UE Rx表示该下行参考信 号到达 UE的时刻。 为了得到 UE的 RTT, 理想的情况是, eNB将 UE的发 送时刻进行 TA调整, 调整到虚线的位置; 这样 UE发送上行信号到达 eNB 的时刻正好是 eNB发送下行信号的时刻。从图中就可以看出,所需要的 RTT 时间 , 就是 eNB的接收时间减发送时间 ( Rx-Tx )加上 UE的 Rx-Tx。 由于 UE和服务 eNB是同步的, 因此这里的 Rx和 Tx对应的都是同一个子帧的 发送和接收时间; 即, RTT时间是 eNB的上行信号接收时间减同子帧下行 信号发送时间 ( Rx-Tx )加上 UE的所述下行信号之接收时间减所述上行信 号之发送时间 (Rx-Tx ) 。 利用所估计的 RTT, 可以计算出如图 1 所示的 UE与服务 eNB的距离 S。 服务 eNB可以利用其阵列智能天线进一步得到 UE的 AoA。 从而通过距离 S和到达角 AoA以及 eNB的位置可以确定 UE 的位置。 由于 UE只有一个服务 eNB , 因此上述 AoA和 eNB的 Rx-Tx测量 只能通过唯一的服务基站获得。 然而, 如果能够根据多个 eNB与 UE的距 离进行位置估计, 能够在 e-CID的基础上帮助进一步提高定位准确性。
本发明利用了 CoMP场景的特性来改进 e-CID定位。 由于在 LTE的多 小区场景中, 存在不同小区间的同频干扰, 因此引入了 CoMP场景来降低 同频干扰, 增加***吞吐量。 图 3示出了 CoMP场景下帮助定位 UE的示 意图, 在 CoMP场景下, 由于 CoMP集合内的基站与相关联的 UE是同步 的 , 因此都可以如同 UE的服务基站那样进行对于 UE的 eNB侧 Rx-Tx测 量, 以及可选地可以进行对于 UE的 AoA估计。 如上所述, 根据各个 eNB 测量的 Rx-Tx (即, UE发送的上行参考信号到达 eNB的时间减去 eNB在 相同子帧中发送下行参考信号的时间)以及 UE测量的 Rx-Tx (即上述下行 参考信号达到 UE的时间减去 UE发送上述上行参考信号的时间), 可以估 计出 UE与各个 eNB间的 RTT, 进而得到各个 eNB与 UE之间的距离, 从 而通过 CoMP集合内的多个基站可以为 UE定位。
虽然在具体实施例中描述了对 UE进行定位,但是本领域技术人员应该 理解, UE可以代表任何移动终端、 移动台、 手持设备等, 也可以代表需要 进行定位的任何其他类型的设备。
图 4A示出了在 CoMP场景下对 UE进行定位的示例性方法。由于 CoMP 集合内的基站都可以进行 eNB侧的 Rx-Tx测量, 如图所示, 利用 CoMP集 合内的三个 eNB针对 UE分别测量的 eNB侧 Rx-Tx和 UE相对于这三个 eNB 分别测量的 UE侧 Rx-Tx, 可以得到 UE相对于这三个 eNB的三个 RTT, 根据三边法, 在没有获取 AoA信息的前提下, 由三个 RTT可以确定 UE的 位置。 这里需要说明的是, 虽然在该例子中说明了三个 eNB的情况, 但是 本发明的实现不限于三个 eNB的情况,采用任何数量的多个 eNB都可以改 进 e-CID的定位准确性。
为了便于说明, 图 4A中示出了一种理想的情况, 即由三个 RTT确定 的圆弧交于一点, 由此确定 UE的位置。 在实际环境中, 由于无线环境的变 化以及测量的误差, 可能不能得到一个交于一点的位置。 例如, 还是以三 个 eNB的情况为例, 当由三个 eNB为中心的三个圆弧没有交于一点时, 其 两两之间分别有两个交点, 因此一共有六个交点, 从中可以确定最接近的 三个交点,从而该最接近的三个交点确定的范围可以作为 UE的位置。 又例 如,可以将该最接近的三个交点的平均位置或者加权平均位置作为 UE的位 置。 又例如, 可以将所有六个交点的平均位置或者加权平均位置作为 UE 的位置。 需要说明的是, 上述确定 UE位置的方法是示例性的, 任何显而易 见的修改都应该在本发明的保护范围之内。
通过采用本发明实施例提供的方法, 在 CoMP场景获得多个 AoA可以 进一步提高 UE的定位准确度。
图 4B示出了在 CoMP场景下对 UE进行定位的示例性方法。 在该例子 中, CoMP集合内的基站能够针对 UE进行 AoA测量。 可以将 AoA定义为 UE上行信号到达 eNB的到达方向 (如图中实线所示)与基准方向 (如图 中虚线所示, 例如以 eNB为端点水平向右的射线, 也可以是其他角度的射 线)之间的夹角。 需要说明的是, 为了简洁图中只画出了 eNBl的基准方向 线, eNB2和 eNB3也具有相同角度的基准方向线。 如图所示, CoMP集合 内的三个 eNB利用智能天线阵列针对 UE分别测量的该 UE相对于 eNB的 三个 AoA。 根据几何算法, 例如解析几何方法, 根据 eNB的位置和 AoA 角度确定的三条射线, 可以确定 UE的位置。 这里需要说明的是, 虽然在该 例子中说明了三个 eNB的情况,但是本发明的实现不限于三个 eNB的情况, 采用任何数量的多个 eNB都可以改进 e-CID的定位准确性。 例如, 利用两 个 eNB得到的两条射线也可以确定 UE的位置。 为了便于说明, 图 4B中示出了一种理想的情况, 即由三个 AoA确定 的射线交于一点, 由此确定 UE的位置。 在实际环境中, 由于无线环境的变 化以及测量的误差, 很可能不能得到一个交于一点的位置。 例如, 还是以 三个 eNB的情况为例, 当由三个 eNB为原点的三条射线没有交于一点时, 其两两之间分别有一个交点, 因此一共有三个交点, 从而该三个交点确定 的范围可以作为 UE的位置。又例如,可以将该三个交点的平均位置或者加 权平均位置作为 UE的位置。 需要说明的是, 上述确定 UE位置的方法是示 例性的, 任何显而易见的修改都应该在本发明的保护范围之内。 例如, 结 合由 CoMP场景中的多个基站获得的多个 RTT和 AoA, 可以进一步改进 UE的位置估计。例如,通过综合考虑利用多个基站获得的多个 RTT和 AoA 所确定的多个位置, 采用加权平均(或称之为补偿)的方法, 可以改善 UE 位置估计的稳定性, 使得某个区域无线环境的突然变化不会严重恶化定位 的准确性。
上述定位准确性的改善归根结底是通过利用 CoMP场景的性质所带来 的, 换言之, 本发明实施例提供了一种利用 CoMP场景的性质帮助改善 UE 定位的方法。
图 5 A-5F示出了本发明的用于帮助改善 UE定位的实施例的示意图。 在 CoMP场景下, UE当前的主服务 eNB既可以与 CoMP集合中其他 的邻 eNB共同作为服务基站, 这种情况下, 定位服务器例如增强的服务移 动定位中心 ( e-SMLC, Enhanced Serving Mobile Location Centre )可以分另 ll 与这些 eNB都有信令交互; 也可以主服务 eNB与其他的一些节点 (例如: 接入点 (AP, Access Point ) , 远端射频头 (R H, Remote Radio Head ) ) 一起作为服务基站, 这种情况下, e-SMLC与主服务 eNB进行信令交互, 再由主服务 eNB将测量指令转发至下属的节点。 另一方面, e-SMLC与 UE 的信令交互可以采用两种方式, 一种是 e-SMLC通过 LTE定位协议 ( LPP, LTE Positioning Protocol )信令直接通知 UE 进行定位测量, 例如相对于 CoMP集合中的多个服务基站分别进行 e-CID测量,另一种是 e-SMLC先通 过 LTE定位协议 a ( LPPa, LTE Positioning Protocol A )信令请求 eNB进行 定位测量, 然后 eNB再通过线电资源控制 (RRC, Radio Resource Control ) 信令通知 UE进行定位测量。 在 UE以及服务基站完成各自的定位测量后, 所得到的测量结果, 例如 UE相对于各个服务基站测量的 Rx-Tx以及各个 服务基站针对 UE测量的 Rx-Tx和 /或 AoA, 被上报给定位服务器, 定位服 务器利用测量得到的这些参数来确定 UE的位置。
图 5A示出了根据本发明一个实施例的帮助改善 UE定位的方法的示意 图。 在该实施例中, 主服务 eNB和其他节点 AP共同作为服务基站构成关 联于 UE的 CoMP集合。 在步骤 1A中, e-SMLC通过 LPPa信令向主服务 eNB发送询问消息 , 以询问主服务 eNB的 CoMP状态 , 从而确定 UE是否 处于 CoMP状态下或称 CoMP服务状态下。 在步骤 2A中, eNB通过 LPPa 信令就自己的状态回应 e-SMLC。 在步骤 3A中, 如果 e-SMLC确定 UE处 于 CoMP状态下, e-SMLC通过 LPPa信令向主良务 eNB发送定位测量请求 消息, 以请求 CoMP集合中的多个基站进行与 UE定位有关的测量, 例如 针对该 UE测量基站侧 Rx-Tx值和 /或 AoA。 在步骤 4A, 主服务 eNB通过 RRC信令向 UE发送定位测量请求消息, 该消息指明 UE需要与哪些基站 进行定位测量,例如该消息将 CoMP集合中包含的所有或部分基站告知 UE, 以指示 UE相对于 CoMP集合中的多个基站进行定位测量, 例如相对于多 个基站测量 UE侧的 Rx-Tx值。 同时, 在步骤 4A中, 主服务 eNB向 CoMP 集合中的下属 AP (例如 API , AP2 )发送定位测量请求, 以指示下属 AP 针对 UE进行定位测量。 在步骤 5A中, UE和下属 AP将测量结果上报给 主服务 eNB, 这里, UE可以通过 RRC信令向主服务 eNB上报测量结果, 而 eNB与下属 AP之间的信令与 AP的配置有关,对于不同类型的 AP可以 采用相应的信令。 在步骤 6A, eNB 通过 LPPa信令将测量结果上报给 e-SMLC。 在收到来自多个服务基站以及 UE的测量结果后, e-SMLC可以 利用多组定位参数确定 UE的位置,例如通过上文中描述的方法确定 UE位 置。
在该实施例中, AP 和 UE 的测量结果都是通过主服务 eNB 上报给 e-SMLC的。 e-SMLC先通过 LPPa信令请求主服务 eNB进行定位测量, 主 服务 eNB转发测量指令给下属的其他节点; 然后主服务 eNB通过 RRC信 令知会 UE进行定位测量; UE通过 RRC信令上报测量结果给主服务 eNB; 各个节点发送测量结果给主服务 eNB, 主服务 eNB汇总后通过 LPPa报告 测量结果给 e-SMLC。
图 5B示出了根据本发明一个实施例的帮助改善 UE定位的方法的示意 图。 该实施例与图 5A所示实施例的区别在于, e-SMLC通过 LPP信令直接 向 UE发送定位测量请求,以指示 UE相对于 CoMP集合中的多个基站进行 定位测量, 以及 UE通过 LPP信令将测量结果直接上报给 e-SMLC。具体而 言,在步骤 1B中, e-SMLC询问主服务 eNB的 CoMP状态。在步骤 2B中, 主服务 eNB回应 e-SMLC。 在步骤 3B中, e-SMLC通过 LPPa信令向主服 务 eNB发送定位测量请求消息, 以请求主服务 eNB及其下属 AP针对 UE 进行定位测量,同时, e-SMLC通过 LPP信令向 UE发送定位测量请求消息, 以请求 UE相对于 CoMP集合中的多个基站进行定位测量, 该多个基站可 以包括主服务 eNB及其下属的 AP。 在步骤 4B中, 主服务 eNB向下属 AP 转发定位测量请求, 以请求 AP针对 UE进行定位测量。 在步骤 5B中, AP 将测量结果上报给主服务 eNB。 在步骤 6B中, 主服务 eNB和 UE分别通 过 LPPa和 LPP将测量结果上艮给 e-SMLC。
