Description

位置信息的测量及其实现方法、终端及接入网网元
本申请要求在2018年04月03日提交中国专利局、申请号为201810292079.8的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，例如涉及的是一种位置信息的测量及其实现方法、终端及接入网网元。
背景技术
随着通信技术的不断发展，无线保真(Wireless Fidelity，Wifi)技术和蓝牙(Bluetooth，BT)技术广泛地被人们使用。相关的Wifi技术和蓝牙技术可以用作第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)系统潜在的室内定位增强技术。
Wifi定位系统被广泛用于商业定位服务(基于移动位置服务(Location Based Service，LBS))。用户设备(User Equipment，UE)利用Wifi接收器收集定位节点(Wifi节点)的接收的信号强度指示(Received Signal Strength Indication，RSSI)和其他信息，借助定位节点的位置或覆盖区域的数据库来确定位置。蓝牙定位系统中，蓝牙低能量(Bluetooth Low Energy，BLE)信标被认为是一种潜在的技术，为用户设备提供位置信息和相关上下文交互。蓝牙信标是利用蓝牙低能量广播蓝牙信号的发射机。当用户设备处于蓝牙信标接近时，用户设备可以获得蓝牙信标标识，并且蓝牙信标位置可以从数据库查询中获得。
为了降低运营商利用专用设备进行人工路测的成本和复杂性，3GPP在通用陆地无线接入网(Universal Terrestrial Radio Access Network，UTRAN)和演进的通用陆地无线接入网(Evolved Universal Terrestrial Radio Access Network，E-UTRAN)系统的版本10(Release-10)开始引入最小化路测(Minimization of Drive Test，MDT)功能。
最小化路测功能利用用户设备(或称为终端)自动收集测量信息通过控制面(Control Plane)信令报告给无线接入网(Radio Access Network，RAN)的相关网元，对于UTRAN系统，RAN的相关网元主要是指RNC，对于E-UTRAN 系统RAN的相关网元主要是指演进基站(evolved Node B，eNB)，再通过无线接入网报告给操作维护系统(OperationAnd Maintenance，OAM)的跟踪收集实体(Trace Collection Entity，TCE)，用于网络优化，例如发现及解决网络覆盖问题。
随着Wifi技术和蓝牙技术的广泛应用，如何利用Wifi或蓝牙技术实现室内定位或支持室内定位的最小化路测功能是需要解决的技术问题。

具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，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任意组合。
图1显示了一种室内定位系统的示意图，在无线通讯系统和蓝牙(或Wifi)定位技术结合下，基站覆盖范围内预先部署运营商(或运营商委托的第三方)的蓝牙或Wifi定位节点设备。基站通过信令配置要求终端实现室内定位节点的测量和上报。支持室内定位的终端移动到这些定位节点附近时，获得这些定位节点的媒体接入层(媒体访问控制(Media Access Control，MAC))地址信息和信号强度信息，上报给基站。基站获得信息后再上报给计算位置的网络设备。
3GPP在UTRAN和E-UTRAN系统的版本10(Release-10)开始引入最小化路测MDT功能。UTRAN包括节点B(Node B)和无线网络控制器(Radio Network Controller，RNC)。E-UTRAN包括演进节点B(eNB)。UTRAN对应的核心网(Core Network，CN)包括宿主用户服务器(Home Subscriber Server，HSS)、移动交换中心服务器(Mobile Switching Centre Server，MSCS)、服务的 GPRS支持节点(Serving GPRS Support Node，SGSN)等。E-UTRAN对应的核心网包括HSS、移动管理实体(Mobile Management Entity，MME)等。
MDT功能分为基于管理的MDT(Management based MDT)和基于信令的MDT(Signaling based MDT)。以E-UTRAN系统为例，基于管理的MDT的激活过程通常是操作维护或称网管系统(Operations Administration and Maintenance，OAM)发送包含MDT配置的跟踪激活消息(Trace session activation)给eNB，eNB在该消息规定的区域(Area)内选择合适的UE，并将所述MDT配置信息发送给选中的UE。基于信令的MDT的激活过程是由OAM发送包含MDT配置的跟踪激活消息给HSS以激活指定UE的MDT测量，HSS将所述UE的MDT配置信息发送给MME，MME将该UE的MDT配置信息发送给eNB，eNB最终将MDT配置信息发送给UE。基于信令的MDT通常用国际移动用户标识(International Mobile Subscriber Identity，IMSI)或国际移动站设备标识(International Mobile Station Equipment Identity，IMEI)来指定某个UE，或加上区域信息以限制UE的选择。基于管理的MDT和基于信令的MDT激活消息中包含来自OAM的跟踪参考(Trace Reference)信息，其中包括公共陆地移动网络(Public Land Mobile Network，PLMN)信息，所述PLMN信息由移动国家码(Mobile country code，MCC)和移动网络码(Mobile Network code，MNC)组成。
终端进行定位测量时，室内除了有运营商部署的蓝牙或Wifi定位节点设备外，还可能存在非运营商提供的蓝牙设备(比如，车载终端或手持终端)或者私人配置的Wifi设备，这些非运营商的蓝牙设备或Wifi设备信息对于计算位置信息毫无帮助。相关技术中，终端并不能区分运营商与非运营商的蓝牙设备或WiFi设备，在测量时会一并上报。因此在测量报告中将会携带大量的无效信息。这些无效信息将会消耗宝贵的空中接口资源，也会浪费定位计算资源。
本申请实施例的技术方案提出一种位置信息的测量及其实现方法，终端按照网络侧的要求(比如筛选定位节点)进行定位测量，从而节省定位测量过程中消耗的空中接口资源和计算资源。

下面通过一些示例说明本申请位置信息的测量及其实现方法。

如图6所示，本示例提出的一种实现位置信息测量的方法，包括：步骤1至步骤4。
在步骤1中，位置计算中心节点通过基站将定位辅助信息发送给终端。
在步骤2中，终端根据定位辅助信息过滤定位节点。
例如，某些运营商会将部署的蓝牙节点或Wifi节点统一命名，这些蓝牙节点或Wifi节点的设备名称具有特定的字符串，这些字符串就是定位节点设备的特征。
