Description
定位处理方法、 装置及系统 技术领域 本发明涉及无线通信技术, 尤其涉及一种定位处理方法、 装置及系统。 背景技术
定位技术是利用无线通信网络的资源直接或者间接地得到终端的地理位 置信息的业务。 OTDOA ( Observed Time Difference of Arrival , 观察到达时间 差) 定位是一种常用的终端定位方法。
OTDOA定位原理是: 当无线蜂窝网络中存在三个或三个以上的基站时, 网络侧的定位服务器可以根据不同基站发送的下行传输信号到达终端的时间 差确定终端的位置。 图 1为现有技术提供的 OTDOA定位原理的示意图, 如 图 1所示, 终端 105所在小区的服务基站为第一基站 100, 无线蜂窝网络中 还存在第二基站 101和第三基站 102, 其中, 终端 105到第一基站 100的距 离为 。, 终端 105到第二基站 101的距离为^ 终端 105到第三基站 102的距 离为 4 , 因此, 可以选择第一基站 100、 第二基站 101和第三基站 102作为终 端 105 的定位基站。 定位服务器为各定位基站和终端指定 PRS ( Positioning Reference Signal, 定位参考信号) 的发送和接收配置之后; 三个基站同时向 终端下行发送 PRS , 终端接收到来自各定位基站的 PRS , 并识别每个 PRS的 首达径位置, 可以得到不同基站之间的 PRS到达时间差, 并将其上报至定位 服务器。 定位服务器通过终端接收的不同定位基站发送的信号时间差, 可以 映射成终端与不同定位基站之间的距离差, 再由双曲线的定义知, 到两个定 点距离之差为恒定值的点构成一条双曲线。 例如, 在图 1 中, 终端 105到第 一基站 100和第二基站 101 的距离差为 4 -4 , 对应第一曲线 103 , 终端 105 到第二基站 101和第三基站 102的距离差为 -4 , 对应第二曲线 104, 第一 曲线 103和第二曲线 104的交点即为终端 105的位置。 当系统中存在的基站 数量增加时, 能够提高终端定位的精度。
目前,多模终端已成为终端设备发展的趋势,例如,终端既能够支持 ISM ( Industrial, Scientific and Medical , 工业的, 科学的及医疗的)频带又能够支
持 LTE ( Long Term Evolution, 长期演进) 的频带。 这种多制式的终端, 由 于 LTE频带与 ISM频带的共存,会引入一些新的干扰,例如, IDC ( In-device Coexistence, 设备内共存)干扰, 终端发射的 WiFi ( Wireless Fidelity, 无线 相容性认证)或蓝牙信号对终端接收 LTE信号产生干扰, 终端发送的 LTE 信号对终端接收 GPS ( Global Positioning System, 全球定位系统)信号产生 干扰, 终端发送的 LTE信号对终端接收 WiFi或者蓝牙信号产生干扰等。
因此, 在 OTDOA定位过程中, 若存在影响定位信号接收的干扰信号, 则对定位信号时间差的测量造成影响, 导致对终端位置的定位误差增加。 发明内容 本发明实施例提供一种定位处理方法、 装置及系统, 用以提高对终端 位置定位的精确度。

图 2为本发明定位处理方法实施例一的流程图。 本实施例的处理方法 适用于通过 OTDOA定位方式对用户终端的位置定位, 该方法可以由定位 服务器来执行,也可以由服务器侧的其它定位处理装置执行。如图 2所示, 本实施例的方法可以包括:
S201、 获取终端的共存干扰信息;
定位服务器通过 OTDOA定位方式对用户终端进行定位的过程中, 首 先获取终端的共存干扰信息, 进而可以根据该共存干扰信息为终端指定合 适的信号资源让终端进行定位测量。共存干扰指蜂窝移动通信系统与 WIFI 和 /或蓝牙和 /或 GPS的干扰等。
S202、 根据共存干扰信息指示终端在合适的定位信号资源上进行测 量;
定位服务器获取终端的共存干扰信息后, 可以为终端指定适用的定位 信号测量资源进行定位测量, 所述定位信号包含但不限于定位参考信号 ( PRS ) 。 例如, 定位服务器获取的终端的共存干扰信息可以是终端受干 扰严重或者是不适合终端进行定位测量的频域、 时域和 /或码域资源信息, 也可以是终端受干扰不严重或者是适合终端进行定位测量的频域、 时域和 /或码域资源信息, 因此, 定位服务器可以为该终端指定不受共存干扰或者 受共存干扰不严重的频域、 时域和 /或码域资源作为测量定位信号的资源, 并通过辅助数据告知终端在合适的定位信号测量资源上进行定位测量。
S203、 基于终端上报的定位测量结果对终端进行定位。
具体的, 定位服务器根据共存干扰信息, 为终端指定合适的定位测量 资源, 并通过辅助数据通知终端; 终端根据辅助数据的指示接收来自各定 位基站的 PRS , 并记录接收到各定位基站发送的 PRS的时间点,得到各定 位基站的 PRS到达终端的时间差, 并将其上报至定位服务器; 定位服务器 根据终端接收到不同定位基站发送的 PRS的时间差,通过数学计算确定终 端的位置。
本实施例中, 定位服务器在对用户终端 OTDOA定位过程中, 通过获 取终端的共存干扰信息, 并根据共存干扰信息为终端指定在合适的定位信 号测量资源上进行测量, 减小了干扰信号对定位信号的影响, 提高了对终 端位置定位的精确度。
如上所述的定位处理方法, 其中, 若所述共存干扰信息包括所述终端 对频域、 时域和 /或码域传输资源的适用状态信息, 则所述根据所述共存干 扰信息指示所述终端在合适的定位信号资源上进行测量, 具体可以包括: 根据所述共存干扰信息为所述终端指定适用的频域、时域和 /或码域传 输资源作为适合所述终端进行定位测量的定位信号测量资源。
具体的, 终端的共存干扰信息可以包括终端的适用频域资源信息或不 适用频域资源信息, 和 /或, 终端的适用时域资源信息或不适用时域资源信 息, 和 /或, 终端的适用码域资源信息或不适用码域资源信息。 例如, 在 LTE网络中, 受 IDC干扰或受 IDC干扰严重的频域、 时域、 码域资源, 为终端的不适用频域、 时域、 码域资源信息; 不受 IDC干扰或受 IDC干 扰不严重的频域、 时域、 码域资源, 为终端的适用的频域、 时域、 码域资 源信息。
本实施例中, 定位服务器在对用户终端 OTDOA定位过程中, 通过根 据终端的共存干扰信息为终端指定适用的频域、时域和 /或码域资源进行定 位测量, 减小了干扰信号对定位信号的影响, 提高了对终端位置定位的精 确度。
图 3为本发明定位处理方法实施例二的流程图。 如图 3所示, 在图 2 所示本发明方法实施例一的基础上, 在 S203 中所述基于终端上报的定位 测量结果对终端进行定位, 具体可以包括:
S301、将指定的定位信号测量资源作为定位测量的辅助数据提供给终 端, 其中, 辅助数据至少包括发送定时和 /或发送频点;

S302、接收终端基于辅助数据测量得到的定位信号从不同定位基站到 达终端的时间差;
具体的, 定位服务器根据共存干扰信息, 为终端指定了合适的定位信 号测量资源进行定位测量, 并通过辅助数据通知终端; 终端根据辅助数据 的指示接收来自各定位基站的 PRS , 并记录接收到各定位基站发送的 PRS 的时间点,得到各定位基站的 PRS到达终端的时间差, 并上报至定位服务 器。
S303、根据时间差进行计算,得到终端与不同定位基站之间的距离差, 根据距离差确定终端的位置。
定位服务器可以根据各定位基站的 PRS到达终端的时间差和 PRS的 传播速度计算出终端与不同定位基站之间的距离差, 确定终端的位置。 增 加定位基站数量, 可以进一步提高终端定位的精确度。
本实施例中, 定位服务器在对用户终端 OTDOA定位过程中, 通过将 指定的包含发送定时和 /或发送频点的定位信号测量资源作为定位测量的 辅助数据提供给用户终端, 减小了干扰信号对定位信号的影响, 提高了对 终端位置定位的精确度。

扰信息的请求消息。
接收终端直接上 ·¾, 或经基站转发, 或经 MME和 OAM转发的共存 干扰信息。
定位服务器接收的共存干扰信息可以是单个 UE的共存干扰信息, 也 可以是多个 UE的共存干扰信息。 例如, 在 LTE网络中, 终端可以将自身 的共存干扰信息通过 LTE定位协议信令直接发送给定位服务器;终端还可 以将自身的共存干 ·ί尤信息通过 RRC ( Radio, Resource Control, 无线资源控 制层)信令发送给基站, 基站通过 LTE定位协议 A信令主动将终端的共 存干扰信息上报给定位服务器, 或者在定位服务器通过 LTE 定位协议 A 信令向基站发送上报终端的共存干扰信息的请求消息后, 基站通过 LTE 定位协议 A信令将终端的共存干扰信息发送给定位服务器;在终端将自身 共存干扰信息通过 RRC信令发送给基站后, 基站还可以将终端的共存干 扰信息发送给 MME ( Mobile Management Entity, 移动管理实体) , MME 将终端的共存干 4尤信息再转发给 OAM ( Operations, Administration and Maintenance, 操作, 管理及维护实体) , OAM将收集的终端的共存干扰 信息发送给定位服务器, 进而, 定位服务器可以根据终端的共存干扰信息 为终端指定合适的定位信号测量资源进行定位测量, 然后根据终端上报的 定位测量结果对终端进行定位。
本实施例中, 通过定位服务器向用户终端发送上报终端的共存干扰信 息的请求消息, 或者终端将自身的共存干扰信息主动发送给定位服务器, 使得定位服务器在对用户终端 OTDOA定位过程中, 能够及时获得终端的 共存干扰信息, 减小了干扰信号对定位参考信号的影响, 提高了对终端位 置定位的精确度。
