基于小基站的定位用户终端的方法和小基站控制器
技术领域

定位技术是为了确定移动台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移动台的位置信息。 LTE中采用的标准终端 定位的方式有以下几种:网络辅助的 GNSS ( Global Navigation Satellite System , 全球导航卫星***) 定位、 OTDOA(Observed Time Difference of Arrival , 可 观察到达时间差)方式、 e-CID ( evolved-Cell Identity, 演进小区标识)定位和 UTDOA ( Uplink Time Difference of Arrival , 上行到达时间差) 方式。
LTE 的移动台定位算法一般可以通过检测移动台和基站之间无线电波传 播信号的特征参数 (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移动终端的几何位置。 GNSS的定位方法要求终端 具有接收 GNSS信号的无线接收器, GNSS的具体实现包含 GPS定位, Galileo 定位等等。 OTDOA定位和 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检测, 再根据定位算法来估计移动台位 置, 是当前研究的热点。 OTDOA定位利用移动台接收来自多个基站的下行定 位参考信号并进行定时测量, 并上报基站间的 PRS到达时间差, 在网络定位 服务器上进行计算得到移动台的地理位置。 UTDOA定位根据多个 LMU (定位 测量单元, Location Measurement Unit)和 /或基站接收到移动台发送的上行信 号, 进行定时测量, 并上报上行信号的到达时间; 在定位服务器上进行计算得 到移动台的地理位置。
对于定位精度的需求,美国联邦通信委员会(FCC )于 1996年公布了 E-911 条例,要求在 2001年 10月 1 日前, 美国各电信运营商的无线蜂窝***必须能 够对发出 E-911紧急呼叫的移动台提供精度在 125m内的定位服务, 而且满足 此定位精度的概率应不低于 67%。 1998年又提出了定位精度为 400m, 准确率 不低于 90%的服务要求。 1999年 FCC对定位精度提出新的要求: 对基于网络 的定位, 67%的定位精度要在 100m以内, 95%的定位精度要在 300m以内; 对基于移动台的定位, 67%的精度要在 50m以内, 95%的精度要在 150m以内。
目前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 位服务的应用场景呈现出多元化的趋势, 例如紧急求援定位, 犯罪位置追踪, 导航及交通控制等等。但不论应用场景如何多样, 业界对于定位的需求始终是 希望获得可靠、 有效、 快速的方法, 换言之, 易于实现并且高精度的定位技术 一直是人们追捧的热点。
另外, 为了增加覆盖和用户体验, 目前的研究希望在原有的无线网络中增 加 small cell (小小区)的覆盖, 用来增强覆盖和用户的体验。 但是随着新的场 景(small cell的小基站) 的引入, 定位服务器若需要对小基站进行测量配置, 则需要通过宏基站与小基站控制器连接,再由小基站控制器连接小基站, 因此 目前的 LPPa ( LTE Positioning Protocol A, 长期演进定位协议 A )信令无法完 成这个信令的交互过程, 也就是说, 通过 LPPa信令承载了定位服务器和宏基 站之间的交互; 但是为了连通宏基站与小基站,还需要在宏基站与小基站控制 器以及小基站控制器与小基站间进行新的接口和信令的定义,已保证定位的测 量配置及测量报告能够在定位服务器与小基站间交互。 发明内容

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是 全部的实施例。基于本发明中的实施例, 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
参见图 1-图 4, 为本发明实施例的小基站的网络结构图,
为了增加覆盖和用户通信质量, 在原有的无线网络中增加小基站以形成 small cell的覆盖, 图 1中描述了 small cell的基站与宏基站的连接情况, small cell的基站并没有与 MME ( Mobility Management Entity, 移动管理实体 )或者 核心网直接连接, 宏基站作为一个中间节点, 作为连接 small cell的基站与核 心网或者 MME的作用。在图中可以看出, small cell可能与宏基站对应的宏小 区的覆盖交叠, small cell也有可能是一个隔离的小区。
由于在某个区域内可能部署较多的小基站,例如在某个大楼的每一楼层都 可能部署若干个小基站, 这些小基站形成了每一楼层的多个小小区, 来为这一 楼层的终端提供服务。多个小小区以集群的形式存在于宏蜂窝覆盖的不同位置 是一个比较普遍的现象,在本发明中引入了小基站控制器的概念,原来小基站 连接宏基站的连线变成了多个小基站连接到小基站控制器,然后由小基站控制 器连接到宏基站。
参见图 2, 为本发明的场景 1 , 宏小区对应的宏基站与小小区对应的小基 站连接(宏小区与小小区处于同频 F1上 ), 同一集群内的小基站之间有协调的 连接线, 此时把与宏小区的宏基站连接的小基站视为该集群内的小基站控制 器。
参见图 3 , 为本发明的场景 2, 宏小区对应的宏基站与小小区对应的小基 站连接(宏小区与小小区处于不同频点 F1与 F2上), 同一集群内的小基站之 间也有协调的连接线,此时把与宏小区的宏基站连接的那个小小区的小基站视 为该集群的小基站控制器。场景 1和 2之间的区别在于部署的小小区是位于室 外的场景还是室内。
参见图 4, 为本发明的场景 3 , 小小区对应的小基站不与宏小区对应的宏 基站连接, 同一集群内的小基站之间存在协调的连接线, 此时指定集群内的一 个小基站作为该集群被的小基站控制器,如图中指定中间的小基站为小基站控 制器, 这个场景是位于室内的小小区部署场景。
