Description

定位方法和装置
技术领域
本发明实施例涉及通信技术领域, 尤其涉及一种定位方法和装置。 背景技术
随着移动通信技术的不断发展, 对于定位服务的需求也日渐增加。 定 位技术是为了确定移动终端的地理位置而采用的技术, 在移动通信网络 中, 定位服务器可以利用无线通信网络的资源直接或者间接地得到移动终 端的位置信息。 目前, 在长期演进 (Long Term Evolution, 简称: LTE) 中采用的标准终端定位方式有增强型小区标识 ( enhanced Cell Identification, 以下简称: e-CID ) 定位和观察到达时间差 ( Observed Time Difference of Arrival, 以下简称: OTDOA ) 定位等。
其中, e-CID定位主要是根据移动台所处的小区的标识 (ID ) 、 目标 终端的收发时间差、服务基站的收发时间差和服务基站接收到目标终端的 发射信号的到达角 (Angle of Arrival, 以下简称: AOA ) 来计算得到目标 终端的地理位置。 OTDOA定位作为一种网络辅助终端定位的技术, 其实 现过程是: 在网络侧增强的服务移动定位中心 (Enhanced Serving Mobile Location Centre , 以下简称: e-SMLC ) 为告知基站和移动终端指定定位 参考信号 (Positioning Reference Signal, 以下简称: PRS ) 的发送和接收 配置之后,基站下行发送 PRS ,移动终端接收到来自多个定位基站的 PRS , 并识别每个 PRS的首达径位置后, 可以得到不同基站之间的 PRS到达时 间差, 然后移动终端将不同基站之间的 PRS到达时间差上报至 e-SMLC。 e-SMLC接收到的不同基站之间的 PRS到达时间差后, 通过双曲线模型数 学计算, 乘以光速可以映射成移动终端与不同基站之间的距离差, 当获得 移动终端分别与两个基站之间的距离差后, 可以构造出一条定位双曲线, 两条定位双曲线的交点即为移动终端的位置, 这样最终 e-SMLC就可以得 到移动终端的准确位置。
在上述两种定位方法中, 当多个基站共享同一个小区 ID 时 (比如在 某些区域部署一些辅助传输基站或小基站用于覆盖或者容量的增强, 这些 小基站具有相同的小区 ID) , 按照 e-CID定位方法进行定位, 最终会导致 定位的准确性很差。而 OTDOA定位方法中 PRS的信号序列是根据小区 ID 获得的, 同样的, 当多个基站共享同一个小区 ID时, 对于移动终端来说, 这多个基站发送的 PRS都是相同的,因此同样存在定位的准确性很差的问 题。 发明内容
