Description

一种室内定位方法及装置 技术领域
本发明涉及通信技术领域，特别涉及一种室内定位方法及装置。
背景技术
目前，随着移动通信技术的发展和业务需求的增长，基于移动终端位置的定位服务已经越来越多。基于定位的服务涉及交通、物流、治安、紧急情况和日常生活等诸多领域，可以提供导航、物流管理、交通信息、日程安排等众多业务，因此，应用非常广泛。
3GPP(3rd Generation Partnership Project，第三代移动通信标准化组织)协议中定义的定位方法有E-CID(Enhanced Cell Identification，增强型小区标识)定位方法和OTDOA(Observed Time Difference of Arrival，观测时间到达差)定位方法。
E-CID定位方法通常用于蜂窝移动通信中，且易于实现，在这种定位方式中，每个小区都有自己特定的小区标识号(Cell ID)，当进入某一小区时，移动终端要在当前小区进行注册，定位服务器的数据中就会有相应的小区的小区标识。定位服务器根据采集到的移动终端所处小区的标识来确定移动终端的位置。
OTDOA是一种常见的定位方法。如图1所示，移动终端对基站进行监听并测量RSTD(Reference Signal Time Difference，参考信号到达时间差)。每两个基站得到一个测量值，形成一个双曲定位区。这样三个基站得到两个双曲线定位区，求解得出交界点并附加条件可得到移动终端的确切位置。
定位过程最终会得到目标物的水平方向的位置信息和垂直方向的位置信息，在上述两种方法中，无论应用于室外的场景还是室内的场景，定位得到的垂直方向的位置信息均为移动终端的高度(Altitude)和高度不确定度 (Altitude Uncertainty)，但是，当移动终端位于室内时，垂直方向的位置信息用移动终端的高度和高度不确定度来表示的话，定位的准确度较低。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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。
本文中描述的技术可用于各种通信系统，例如当前2G，3G通信系统和下一代通信系统，例如，GSM(Global System for Mobile Communications，全球移动通信系统)，CDMA(Code Division Multiple Access，码分多址)系统，TDMA(Time Division Multiple Access，时分多址)系统，WCDMA(Wideband Code Division Multiple Access Wireless，宽带码分多址)，FDMA(Frequency Division Multiple Addressing，频分多址)系统，OFDMA(Orthogonal Frequency-Division Multiple Access，正交频分多址)系统，单载波FDMA (SC-FDMA)系统，GPRS(General Packet Radio Service，通用分组无线业务)系统，以及其他此类通信系统。
下面结合说明书附图对本发明实施例进行详细说明，应当理解，此处所描述的实施例仅用于说明和解释本发明，并不用于限定本发明，并且在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
下面结合附图对本发明实施例进行详细说明。
室内定位场景示意图如图2A所示。
参阅图2B所示，本发明实施例中，室内定位的一种流程如下：
步骤200：定位服务器获取至少一个基站所处楼层的楼层编号。
本发明实施例中，楼层编号可以为2层、3层，4层等，楼层编号具体携带在消息中时，楼层编号可以为floor index字段中的值。
此处只描述了定位服务器要获取至少一个基站所处楼层的楼层编号，但是如果定位服务器仅仅是确定了楼层编号，不知道楼的位置信息的话，这样的定位也是没有意义的，准确度较低，例如，基站A给定位服务器上报了基站A所处的楼层编号为2层，针对基站A所提供服务的终端1，如果定位服务器将基站A所处楼层的楼层编号作为终端1的垂直位置信息，但是仅仅知道终端1处于2层，不知道终端1处于哪一座楼的话，这样的定位还是没有意义的，因此，本发明实施例中，定位服务器除了要获取至少一个基站所处楼层的楼层编号之外，还要获取至少一个基站所处位置的坐标信息，如(X，Y，Z)，这样，定位服务器就可以根据基站发送的坐标信息确定出基站所处的楼，再根据楼层编号可以确定出终端处于那一层，就可以实现准确定位。
但是，由于现有协议中已经规定了在进行定位时，基站要向定位服务器发送基站所处位置的坐标信息，因此，在此就不再进行详述。
本发明实施例中，定位服务器要获取至少一个基站所处楼层的楼层编号的话，针对至少一个基站中的任意一基站，基站要接收到定位测量请求消息，这样，才可以触发基站发送所处楼层的楼层编号，其中，定位测量请求消息可以是定位服务器发送的，也可以是基站所提供服务的终端发送的，如果是 定位服务器发送的话，定位服务器要在获取至少一个基站所处楼层的楼层编号之前进行发送。
本发明实施例中，定位服务器在发送定位测量请求时，可以是实时发送，也可以是周期性的发送。
本发明实施例中，定位测量请求可以为E-CID MEASUREMENT INITIATION REQUEST。
步骤210：定位服务器接收第一终端的标识信息。
本发明实施例中，第一终端的标识信息可以为TMSI(Temporary Mobile Subscriber Identity，临时移动用户标识)，也可以为IMSI(International Mobile Subscriber Identity，国际移动用户识别码)，当然也可以是其他形式的信息，在此不再进行一一详述。
本发明实施例中，步骤200和步骤210之间是没有先后顺序关系的，也就是说，可以是，定位服务器获取至少一个基站所处楼层的楼层编号之后，定位服务器接收第一终端的标识信息；或者，也可以是，定位服务器接收第一终端的标识信息之后，定位服务器获取至少一个基站所处楼层的楼层编号。
步骤220：定位服务器根据标识信息确定第一终端。
步骤230：定位服务器根据至少一个基站所处楼层的楼层编号，确定第一终端的垂直位置信息。
本发明实施例中，可选的，至少一个基站所处楼层的楼层编号包括第一基站所处楼层的楼层编号，第一基站为第一终端的服务基站。
此时，定位服务器根据至少一个基站所处楼层的楼层编号，确定第一终端的垂直位置信息的方式有多种，可选的，可以采用如下方式：
定位服务器将第一基站所处楼层的楼层编号，作为第一终端的垂直位置信息。
例如：定位区域中有3个基站：基站1、基站2和基站3，定位服务器向3个基站分别发送定位测量请求，基站1所提供服务的终端有10个：终端1-终端10，基站2所提供服务的终端也有10个：终端11-终端20，基站3所提 供服务的终端也有10个终端：终端21-终端30，基站1向定位服务器发送基站1的楼层编号，及终端1-终端10各个终端的标识信息；同理，基站2向定位服务器发送基站2的楼层编号，及终端11-终端20各个终端的标识信息；基站3向定位服务器发送基站3的楼层编号，及终端21-终端30各个终端的标识信息，定位服务器将基站1的楼层编号作为终端1-终端10的垂直位置信息，定位服务器将基站2的楼层编号作为终端11-终端20的垂直位置信息，定位服务器将基站3的楼层编号作为终端21-终端30的垂直位置信息。
上述讲述的是将终端的服务基站所处楼层的楼层编号作为该终端的垂直位置信息，但是，由于准确度较低，因此，为了进一步提高定位的准确度，还可以采用如下方式：
定位服务器根据至少一个基站所处楼层的楼层编号，确定第一终端的垂直位置信息之前，还可以包括如下操作：
定位服务器向N个基站发送参考信号发送通知消息，参考信号发送通知消息用于通知N个基站分别广播参考信号，其中，N为大于0的正整数；
定位服务器向第一终端发送参考信号接收通知消息，参考信号接收通知消息用于通知第一终端接收N个基站广播的参考信号并反馈N个参考信号到达时间差，其中，N个参考信号到达时间差为将N个基站广播的参考信号的到达时间分别与参考基站广播的参考信号的到达时间相减得到的，其中，参考基站为N个基站中的任意一个；
定位服务器接收N个参考信号到达时间差；
定位服务器根据N个参考信号到达时间差确定出到达时间最短的参考信号所对应的基站；
至少一个基站所处楼层的楼层编号包括到达时间最短的参考信号所对应的基站所处楼层的楼层编号。例如：定位区域中有3个基站：基站1、基站2和基站3，基站1所提供服务的终端有终端A和终端B，定位服务器向3个基站均发送参考信号发送通知消息，基站1、基站2和基站3接收到参考信号发送通知消息后均开始广播参考信号，如果定位服务器要定位终端A，则定 位服务器向终端A发送参考信号接收通知消息，终端A接收到参考信号接收通知消息后，接收基站1、基站2和基站3分别广播的参考信号，终端A接收到基站1广播的参考信号的时间为1s，接收到基站2广播的参考信号的时间为2s，接收到基站3广播的参考信号的时间为3s，参考基站为基站3的话，则终端A接收到的基站1广播的参考信号的到达时间差为-2s，终端A接收到的基站2广播的参考信号的到达时间差为-1s，终端A接收到的基站3广播的参考信号的到达时间差为0s，则到达时间最短的参考信号所对应的基站为基站1。
又例如：定位区域中有3个基站：基站1、基站2和基站3，基站1所提供服务的终端有终端A和终端B，定位服务器向3个基站均发送参考信号发送通知消息，基站1、基站2和基站3接收到参考信号发送通知消息后均开始广播参考信号，如果定位服务器要定位终端A，则定位服务器向终端A发送参考信号接收通知消息，终端A接收到参考信号接收通知消息后，接收基站1、基站2和基站3分别广播的参考信号，终端A接收到基站1广播的参考信号的时间为1s，接收到基站2广播的参考信号的时间为2s，接收到基站3广播的参考信号的时间为3s，参考基站为基站1的话，则终端A接收到的基站1广播的参考信号的到达时间差为0s，终端A接收到的基站2广播的参考信号的到达时间差为1s，终端A接收到的基站3广播的参考信号的到达时间差为2s，则到达时间最短的参考信号所对应的基站为基站1。
上述讲述的是针对终端A确定出到达时间最短的参考信号所对应的基站的过程，针对终端B确定到达时间最短的参考信号所对应的基站的过程与针对终端A的过程类似，在此不再进行一一详述。
此时，定位服务器根据至少一个基站所处楼层的楼层编号，确定第一终端的垂直位置信息时，可以采用如下方式：
定位服务器将到达时间最短的参考信号所对应的基站所处楼层的楼层编号，作为第一终端的垂直位置信息。
仍以上述例子为例进行说明，针对终端A，确定出到达时间最短的参考 信号所对应的基站为基站1，那么，将基站1所在楼层的楼层编号，作为终端A的垂直位置信息。同理，如果针对终端B，确定出到达时间最短的参考信号所对应的基站为基站2，那么，将基站2所在楼层的楼层编号，作为终端B的垂直位置信息。
本发明实施例中，定位服务器根据N个参考信号到达时间差确定出到达时间最短的参考信号所对应的基站这个步骤，可以位于定位服务器获取至少一个基站所处楼层的楼层编号这个步骤之前，也可以位于这个步骤之后，如果定位服务器根据N个参考信号到达时间差确定出到达时间最短的参考信号所对应的基站这个步骤，位于定位服务器获取至少一个基站所处楼层的楼层编号这个步骤之前的话，定位服务器根据N个参考信号到达时间差确定出到达时间最短的参考信号所对应的基站之后，只需要获取到达时间最短的参考信号所对应的基站所处楼层的楼层编号就可以了。
如果定位服务器根据N个参考信号到达时间差确定出到达时间最短的参考信号所对应的基站这个步骤，位于定位服务器获取至少一个基站所处楼层的楼层编号这个步骤之后的话，定位服务器根据N个参考信号到达时间差确定出到达时间最短的参考信号所对应的基站之后，从获取的至少一个基站所处楼层的楼层编号中查找到达时间最短的参考信号所对应的基站所处楼层的楼层编号就可以了。
定位服务器根据N个参考信号到达时间差确定出到达时间最短的参考信号所对应的基站这个步骤，与定位服务器获取至少一个基站所处楼层的楼层编号这个步骤之间的先后顺序比较灵活，在此不做具体限定。
同理，为了进一步提高定位的准确度，还可以采用如下方式：
定位服务器根据至少一个基站所处楼层的楼层编号，确定第一终端的垂直位置信息之前，还可以包括如下操作：
定位服务器向M个基站发送参考信号发送通知消息，参考信号发送通知消息用于通知M个基站分别广播参考信号，其中，M为大于2的正整数；
定位服务器向第一终端发送参考信号接收通知消息，参考信号接收通知 消息用于通知第一终端接收M个基站广播的参考信号并反馈M个参考信号到达时间差，其中，M个参考信号到达时间差为将M个基站广播的参考信号的到达时间分别与参考基站广播的参考信号的到达时间相减得到的，其中，参考基站为M个基站中的任意一个；
定位服务器接收M个参考信号到达时间差；
定位服务器接收M个基站发送的M个基站的垂直高度；
至少一个基站所处楼层的楼层编号包括M个基站所处楼层的楼层编号。
例如：定位区域中有3个基站：基站1、基站2和基站3，基站1所提供服务的终端有终端A和终端B，定位服务器向3个基站均发送参考信号发送通知消息，基站1、基站2和基站3接收到参考信号发送通知消息后均开始广播参考信号，如果定位服务器要定位终端A，则定位服务器向终端A发送参考信号接收通知消息，终端A接收到参考信号接收通知消息后，接收基站1、基站2和基站3分别广播的参考信号，终端A接收到基站1广播的参考信号的时间为1s，接收到基站2广播的参考信号的时间为2s，接收到基站3广播的参考信号的时间为3s，参考基站为基站3的话，则终端A接收到的基站1广播的参考信号的到达时间差为-2s，终端A接收到的基站2广播的参考信号的到达时间差为-1s，终端A接收到的基站3广播的参考信号的到达时间差为0s，则定位服务器接收终端A发送的3个参考信号到达时间差-2s、-1s、0s，定位服务器还接收3个基站发送的3个基站的垂直高度，且至少一个基站所处楼层编号包括3个基站所处楼层的楼层编号。
此时，定位服务器根据至少一个基站所处楼层的楼层编号，确定第一终端的垂直位置信息时，可选的，可以采用如下方式：
定位服务器根据M个基站的垂直高度和M个基站的楼层编号之间的映射关系，获取第一函数关系，第一函数关系用于表征楼层编号和垂直高度之间的对应关系；
定位服务器根据M个参考信号到达时间差计算第一终端的垂直高度；
定位服务器根据第一函数关系，将计算得出的第一终端的垂直高度转换 为楼层编号，并将转换得到的楼层编号作为第一终端的垂直位置信息。
例如：基站1的垂直高度为100米，楼层编号为1层；基站2的垂直高度为103米，楼层编号为2层；基站3的垂直高度为106米，楼层编号为3层；根据基站1和基站2可以得出：垂直高度/楼层编号＝(103-100)/(2-1)＝3；根据基站2和基站3可以得出：垂直高度/楼层编号＝(106-103)/(3-2)＝3；根据基站1和基站3可以得出：垂直高度/楼层编号＝(106-100)/(3-1)＝3，则可以得出垂直高度/楼层编号为(3+3+3)/3＝3，则第一函数关系可以为y＝3x+b，其中，y为垂直高度，x为楼层编号，将基站1、基站2或者基站3的任意一基站的垂直高度和楼层编号代入第一函数关系，可以得出b为97，则第一函数关系为y＝3x+97。
又例如：基站1的垂直高度为100米，楼层编号为1层；基站2的垂直高度为106米，楼层编号为2层；基站3的垂直高度为109米，楼层编号为3层；根据基站1和基站2可以得出：垂直高度/楼层编号＝(106-100)/(2-1)＝6；根据基站2和基站3可以得出：垂直高度/楼层编号＝(109-106)/(3-2)＝3；根据基站1和基站3可以得出：垂直高度/楼层编号＝(109-100)/(3-1)＝4.5，则可以得出垂直高度/楼层编号为(6+3+4.5)/3＝4.5，则第一函数关系可以为y＝4.5x+b，其中，y为垂直高度，x为楼层编号，将基站1的垂直高度和楼层编号代入第一函数关系可以得出b为95.5，将基站2的垂直高度和楼层编号代入第一函数关系可以得出b为97,基站3的垂直高度和楼层编号代入第一函数关系可以得出b为95.5，则b为(95.5+95.5+97)/3＝96,则第一函数关系为y＝4.5x+96。
那么在获取第一函数关系之后，如果第一终端的垂直高度为120米，则将120米作为y代入第一函数关系，可以得出x为5.3，此时可以向上取整为6，如果第一终端的垂直高度为118.5米，则将118.5米作为y代入第一函数关系，可以得出x为5。
本发明实施例中，根据M个参考信号到达时间差计算第一终端的垂直高度为目前比较常用的技术，在此不再进行一一详述。
同理，为了进一步提高定位的准确度，还可以采用如下方式：
定位服务器根据至少一个基站所处楼层的楼层编号，确定第一终端的垂直位置信息之前，还可以包括如下操作：
定位服务器向M个基站发送参考信号发送通知消息，参考信号发送通知消息用于通知M个基站分别广播参考信号，其中，M为大于2的正整数；
定位服务器向第一终端发送参考信号接收通知消息，参考信号接收通知消息用于通知第一终端接收M个基站广播的参考信号并反馈M个参考信号到达时间差，其中，M个参考信号到达时间差为将M个基站广播的参考信号的到达时间分别与参考基站广播的参考信号的到达时间相减得到的，其中，参考基站为M个基站中的任意一个；
定位服务器接收M个参考信号到达时间差；
定位服务器接收第一终端发送的M个接收功率，M个接收功率为第一终端对M个基站广播的参考信号进行接收时所采用的功率；
定位服务器接收M个基站发送的M个基站的垂直高度；
至少一个基站所处楼层的楼层编号包括M个基站所处楼层的楼层编号。
此时，定位服务器根据至少一个基站所处楼层的楼层编号，确定第一终端的垂直位置信息时，可选的，可以采用如下方式：
定位服务器根据M个基站的垂直高度和M个基站的楼层编号之间的映射关系，获取第二函数关系，第二函数关系用于表征楼层编号和垂直高度之间的对应关系；
定位服务器根据M个参考信号到达时间差计算第一终端的第一垂直高度；
定位服务器根据M个接收功率计算第一终端的第二垂直高度；
定位服务器根据第一垂直高度和第二垂直高度得到第一终端的最终垂直高度；
定位服务器根据第二函数关系，将计算得出的第一终端的最终垂直高度转换为楼层编号，并将转换得到的楼层编号作为第一终端的垂直位置信息。
本发明实施例中，第二函数的确定方式与第一函数的确定方式类似，在此不再进行详述。
例如：第二函数关系为y＝3x+97，其中，x为楼层编号，y为第一终端的垂直高度，如果计算得出的第一垂直高度为105米，计算得出的第二垂直高度为107米，则可以将第一垂直高度和第二垂直高度的平均值106米作为第一终端的最终垂直高度，此时，将最终垂直高度106米代入第二函数关系，可以得出楼层编号为3层。
又例如：第二函数关系为y＝3x+97，其中，x为楼层编号，y为第一终端的垂直高度，如果计算得出的第一垂直高度为105米，计算得出的第二垂直高度为107米，则可以将第一垂直高度乘以第一权重值80％之积，与第二垂直高度乘以第二权重值20％之积相加之和105.4米作为第一终端的最终垂直高度，此时，将最终垂直高度105.4米代入第二函数关系，可以得出楼层编号为2.8层，向上取整3层，作为第一终端的垂直位置信息。
这样，本发明实施例中，终端处于室内时，定位服务器可以确定出终端具体所处的楼层编号，而不是仅仅得出终端的垂直高度，因此，提高了室内定位的准确度。
参阅图3所示，本发明实施例中，与上述方法实施例对应的室内定位的基站侧流程如下：
步骤300：基站确定所处楼层的楼层编号。
本发明实施例中，楼层编号可以为2层、3层，4层等，楼层编号具体携带在消息中时，楼层编号可以为floor index字段中的值。
此处只描述了基站将所处楼层的楼层编号发送至定位服务器，但是如果定位服务器仅仅是确定了楼层编号，不知道楼的位置信息的话，这样的定位也是没有意义的，准确度较低，例如，基站A给定位服务器上报了基站A所处的楼层编号为2层，针对基站A所提供服务的终端1，但是仅仅知道终端1处于那一层，不知道终端1处于哪一座楼的话，这样的定位还是没有意义的，因此，本发明实施例中，基站除了要将基站所处楼层的楼层编号发送至定位 服务器之外，还要发送基站所处位置的坐标信息，如(X，Y，Z)，这样，定位服务器就可以根据基站发送的坐标信息确定出基站所处的楼，再根据楼层编号可以确定出终端处于那一层，就可以实现准确定位。
但是，由于现有协议中已经规定了在进行定位时，基站要向定位服务器发送基站所处位置的坐标信息，因此，在此就不再进行详述。
步骤310：基站将楼层编号发送至定位服务器。
本发明实施例中，进一步的，该方法还可以包括如下操作：
基站将第一终端的标识信息发送至定位服务器，基站为第一终端的服务基站。
此时，定位服务器可以将楼层编号作为第一终端的垂直位置信息。
本发明实施例中，进一步的，该方法还可以包括如下操作：
基站接收定位服务器发送的参考信号发送通知消息；
基站根据参考信号发送通知消息广播参考信号；
基站为第一终端发送的N个参考信号到达时间差中到达时间最短的参考信号所对应的基站，N个参考信号到达时间差为将N个基站广播的参考信号的到达时间分别与参考基站广播的参考信号的到达时间相减得到的，其中，参考基站为N个基站中的任意一个，其中，N为大于0的正整数。
此时，定位服务器也可以将楼层编号作为第一终端的垂直位置信息。本发明实施例中，进一步的，该方法还可以包括如下操作：
基站接收定位服务器发送的参考信号发送通知消息；
基站根据参考信号发送通知消息广播参考信号；
基站发送基站的垂直高度。
基站发送楼层编号是接收到触发消息才进行发送的，本发明实施例中，进一步的，基站将楼层编号发送至定位服务器之前，还可以包括如下操作：
基站接收定位服务器发送的定位测量请求；或者
基站接收所提供服务的终端发送的定位测量请求。
也就是说，定位服务器发送的定位测量请求可以作为基站发送楼层编号 的触发消息，或者，也可以是基站所提供服务的终端发送的定位测量请求作为基站发送楼层编号的触发消息。
这样，由于基站将基站所处楼层的楼层编号发送至定位服务器，定位服务器可以根据接收到的楼层编号确定终端的垂直位置信息，避免了定位服务器仅仅将终端所处位置的垂直高度作为终端的垂直位置信息，因此，提高了定位的准确度。
如图4A所示，为了更好地理解本发明实施例，以下给出具体应用场景，针对室内定位垂直高度的过程，进行举例描述：
步骤40：定位服务器向定位区域中的3个基站均发送定位测量请求。
该步骤中的3个基站分别为基站A、基站B和基站C。
步骤41：基站A向定位服务器发送基站A所在的楼层编号和基站A所提供服务的终端的标识信息；基站B向定位服务器发送基站B所在的楼层编号和基站B所提供服务的终端的标识信息；基站C向定位服务器发送基站C所在的楼层编号和基站C所提供服务的终端的标识信息。
步骤42：定位服务器针对接收到的标识信息中的任意一标识信息所对应的终端，定位服务器将该终端的服务基站的楼层编号作为该终端的垂直位置信息。
上述讲述的是直接将终端的服务基站的楼层编号作为终端的垂直位置信息，当然，还可以有其他确定方式，如图4B所示：
步骤400：定位服务器向定位区域中的3个基站均发送定位测量请求。
该步骤中的3个基站分别为基站A、基站B和基站C。
步骤410：基站A向定位服务器发送基站A所在的楼层编号和基站A所提供服务的终端的标识信息，并广播第一参考信号；基站B向定位服务器发送基站B所在的楼层编号和基站B所提供服务的终端的标识信息，并广播第二参考信号；基站C向定位服务器发送基站C所在的楼层编号和基站C所提供服务的终端的标识信息，并广播第三参考信号。
步骤420：定位服务器接收到基站发送的楼层编号和终端的标识信息后， 向每一个标识信息所标识的终端均下发通知消息。
步骤430：针对3个基站下的每一个终端，该终端接收到通知消息后，均接收第一参考信号、第二参考信号和第三参考信号，并获得3个参考信号到达时间差，然后将获得的3个参考信号到达时间差发送至定位服务器。
步骤440：定位服务器根据该终端发送的3个参考信号到达时间差确定出到达时间最短的参考信号，并将到达时间最短的参考信号所对应的基站的楼层编号作为该终端的垂直高度信息。
上述讲述的是根据终端发送的参考信号到达时间差确定出到达时间最短的参考信号，并将到达时间最短的参考信号所对应的基站的楼层编号作为终端的垂直高度信息，当然，还可以有其他确定方式，如图4C所示：
步骤4000：定位服务器向定位区域中的3个基站均发送定位测量请求。
该步骤中的3个基站分别为基站A、基站B和基站C。
步骤4100：基站A向定位服务器发送基站A所在的楼层编号、高度信息和基站A所提供服务的终端的标识信息，并广播第一参考信号；基站B向定位服务器发送基站B所在的楼层编号、高度信息和基站B所提供服务的终端的标识信息，并广播第二参考信号；基站C向定位服务器发送基站C所在的楼层编号、高度信息和基站C所提供服务的终端的标识信息，并广播第三参考信号。
步骤4200：定位服务器接收到基站发送的楼层编号、高度信息和终端的标识信息后，确定第一函数关系。
步骤4300：针对3个基站下的每一个终端，该终端接收到通知消息后，均接收第一参考信号、第二参考信号和第三参考信号，并获得3个参考信号到达时间差，然后将获得的3个参考信号到达时间差发送至定位服务器。
步骤4400：定位服务器根据该终端发送的3个参考信号到达时间差计算垂直高度。
步骤4500：定位服务器根据第一函数关系，将垂直高度转换为楼层编号，并将转换得到的楼层编号作为终端的垂直位置信息。
基于上述相应方法的技术方案，参阅图5A所示，本发明实施例提供一种定位服务器，该定位服务器包括获取单元50、接收单元51、确定单元52，其中：

此处只描述了获取单元50要获取至少一个基站所处楼层的楼层编号，但是如果获取单元50仅仅是获取了楼层编号，没获取楼的位置信息的话，这样的定位也是没有意义的，准确度较低，例如，基站A给定位服务器上报了基站A所处的楼层编号为2层，针对基站A所提供服务的终端1，如果确定单元52将基站A所处楼层的楼层编号作为终端1的垂直位置信息，但是仅仅知道终端1处于2层，不知道终端1处于哪一座楼的话，这样的定位还是没有意义的，因此，本发明实施例中，获取单元50除了要获取至少一个基站所处楼层的楼层编号之外，还要获取至少一个基站所处位置的坐标信息，如(X，Y，Z)，这样，确定单元52就可以根据基站发送的坐标信息确定出基站所处的楼，再根据楼层编号可以确定出终端处于那一层，就可以实现准确定位。
