定位的方法及设备
本发明要求2015年7月1日递交的发明名称为“定位的方法及设备”的申请号201510382738.3的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明实施例涉及通信领域，并且更具体地，涉及一种定位的方法及设备。
背景技术
无线接入技术(Radio Access Technology，RAT)能够用于对终端进行定位。并且，不同的无线接入技术由于技术本身特点、频段、基地台站点分布、发射功率、天线配置(数量、方位角等)、接收灵敏度等因素，其覆盖范围和定位性能可能不同。
然而，各无线接入技术对定位都具有一定的误差，并且传统的无线接入技术对终端的定位只能应用于室外的开阔场景，这样导致无法达到定位时的精度和广度的要求。
发明内容
本发明实施例提供了一种定位的方法，该方法使用多种无线接入技术，能够提高定位的精度。
第一方面，提供了一种定位的方法，包括：
获取多种无线接入技术的多个定位信息，所述多个定位信息中的每个定位信息是通过对应的无线接入技术确定的，所述每个定位信息表示终端的位置区域；
根据所述多个定位信息确定所述终端的位置信息。
第二方面，提供了一种用于定位的设备，包括：

确定单元，用于根据所述多个定位信息确定所述终端的位置信息。
本发明实施例中，使用多种无线接入技术对终端进行联合定位，能够提高定位的精度，并且多种无线接入技术的联合定位的方法能够满足室内等场景。
附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1是本发明一个实施例的定位的方法的流程图。
图2是本发明一个实施例的设备的结构框图。
图3是本发明另一个实施例的设备的结构框图。
具体实施方式
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。
应注意，本发明实施例中的无线接入技术也可以称为无线技术，包括但不限于俗称为4G的长期演进(LongTermEvolution，LTE)、无线局域网(Wireless LAN，WLAN)、未来5G等。
应注意，本发明实施例中的终端可以是指移动终端，包括但不限于蜂窝电话、个人数字助手(Personal DigitalAssistant，PDA)、未来5G网络中的终端设备等。
应注意，本发明实施例中的网络设备可以是用于集中管理和控制多种无线接入技术的多个基地台的基地台控制器或基地台服务器，也可以是能够与基地台进行通信的移动管理实体(Mobility ManagementEntity，MME)等，本发明 对此不作限定。
应注意，本发明实施例中的终端和网络设备都支持多种无线接入技术。并且，多种无线接入技术可以独立使用或共享使用相同的软硬件资源，这里的软硬件资源可以包括天线、射频模块、基带模块、处理器、存储系统、用户界面等。当共享使用相同的软硬件资源时，多种无线接入技术可以单独使用或同时使用相同的软硬件资源。
图1是本发明一个实施例的定位的方法的流程图。图1所示的定位的方法可以由终端执行，或者可以由网络设备执行，或者也可以由其他的设备(例如定位服务器)执行。图1所示的方法包括：
S101，获取多种无线接入技术中的多个定位信息，所述多个定位信息中的每个定位信息是通过对应的无线接入技术确定的，所述每个定位信息表示终端的位置区域。
S102，根据所述多个定位信息确定所述终端的位置信息。
本发明实施例中，使用多种无线接入技术对终端进行联合定位，能够提高定位的精度，并且多种无线接入技术的联合定位的方法能够满足室内等场景。
可理解，本发明实施例中，每一种无线接入技术都可以确定定位信息，
其中，采用一种无线接入技术确定终端的定位信息，可以采用现有技术的方法。以无线接入技术A1为例，若该无线接入技术A1的基地台B1能够接收到终端的信号，则该无线接入技术A1的基地台B1可以确定终端的定位信息为：该终端位于该无线接入技术A1的基地台B1的服务范围(小区)内，即确定终端所在的范围。若该无线接入技术A1的基地台B1和基地台B2都能够接收到终端的信号，则可以确定该终端位于基地台B1和基地台B2的小区交集区域，即确定终端所在的小范围。
应注意，每一种无线接入技术所确定的终端的定位信息还与无线接入技术的固有误差有关。例如，若无线接入技术A1的固有误差为50m，那么，该无线接入技术A1所能确定的终端的最小范围是由固有误差确定的，即50m的圆偏差。
可理解，在S101之前，包括：终端向多种无线接入技术的基地台发送上行数据，这样，所述多种无线接入技术的基地台根据上行数据确定所述终端的 定位信息。可选地，该上行数据可以携带终端发送上行数据时的时刻信息。
举例来说，假设无线接入技术A1的固有误差为e1，在t1时刻，终端向该无线接入技术A1的基地台B1发送数据包，该数据包携带发送时刻信息(t1)，那么，基地台B1可以根据接收该数据包的时刻t2与t1之差，确定终端与基地台B1之间的距离为L1。从而，采用该无线接入技术A1所确定的定位信息为：终端与基地台B1之间的距离为L1±e1。
并且，可理解，采用一种无线接入技术所确定的终端的定位信息还与无线信号的传输条件等有关。
S101中，可以从多个无线接入技术的基地台直接获取多个定位信息。或者，可以将多个定位信息汇总到一个基地台(例如基地台B3)，然后再从该一个基地台(例如基地台B3)获取多个定位信息。此时，需要不同无线接入技术的各个基地台之间具有通信接口。不同无线接入技术的定位信息的交互可以具有统一的信息格式，例如，可以包含本区域数字地图内的位置信息；可以包含本无线接入技术的定位的精度信息等。
或者，若图1的方法由网络设备执行，那么，S101中，网络设备可以从终端获取多个定位信息。也就是说，由终端辅助网络设备执行图1的方法。或者，若图1的方法由诸如定位服务器的其他设备执行，S101中，定位服务器也可以从终端获取多个定位信息。也就是说，由终端辅助定位服务器执行图1的方法。
其中，所述多个定位信息是所述终端从所述多种无线接入技术的一个或几个基地台接收到的。例如，终端可以从多个无线接入技术的基地台直接或间接获取多个定位信息之后，再将多个定位信息转发至网络设备。例如，多种无线接入技术将多个定位信息汇总到其中至少一种无线接入技术的基地台之后，终端可以从其中至少一种无线接入技术的基地台(一个或几个)获取多个定位信息。
本发明实施例中，在S102之前，可以包括：接收所述多种无线接入技术的基地台发送的注册信息。那么，S102可包括：根据所述注册信息和所述多个定位信息确定所述终端的位置信息。
其中，注册信息可以包括：基地台的位置信息、所述基地台的频段信息、 所述基地台的发射功率、所述基地台的天线配置信息。
例如，其中的天线配置信息可以包括天线的数量和天线的方位角。这里的方位角可以包括水平方位(azimuth)和垂直方位(elevation)。
例如，其中的基地台的位置信息可以包括基地台的经度信息、基地台的纬度信息和基地台的高度信息。
作为一例，网络设备可以获取其覆盖范围内的多种非卫星无线技术的注册信息。其中，多种非卫星无线技术可包括但不限于：无线接入技术(例如，GSM/WCDMA/LTE和WiMAX等蜂窝无线技术，以及WLAN、Bluetooth、NFC、Zigbee等)和专门用于定位的无线技术(例如，使用多个基地台发射广播信息用于定位的系统)。
网络设备可以记录该注册信息，例如可以对所使用的频段、基地台的位置信息(三维位置，含水平(/horizontal)和垂直(/vertical)位置)、发射功率、天线配置信息(数量、方位角-含水平方位和垂直方位等)等进行登记，并结合所在区域的数字地图形成粗略的覆盖地图。当有新站点加入时，可对登记的信息进行更新。
作为另一例，注册信息是基地台以广播的形式发送的。其中，广播消息可以是基地台在专用信令上发送的。
区域内的终端可以通过广播消息获取该注册信息，例如获取本区域内的一种或多种非卫星无线技术所使用的频段、基地台的位置信息、发射功率、天线配置信息等。
可选地，本发明实施例中，多种无线接入技术可以包括至少一种主无线接入技术和至少一种从无线接入技术。那么，在S102中，可以根据至少一种主无线接入技术的定位信息确定所述终端的位置信息。
也就是说，可以将至少一种主无线接入技术作为主要定位技术，至少一种从无线接入技术作为辅助定位技术。另外，可理解，还可以根据定位性能等进行主从切换。
可选地，在S102中，可以根据定位精度的需求从所述多个定位信息中选择至少一个定位信息；进而根据所述至少一个定位信息确定所述终端的位置信息。
例如，可以根据对定位精度的需求(例如，有无开启地图或导航软件；终端是否长时间处于静止状态等)、终端所在位置等信息，从多种无线接入技术中选择合适的无线接入技术的种类和数量。
这样，只需要根据多种无线接入技术中的一种或几种的定位信息确定终端的位置，能够节省计算时间，提高定位的效率。
可选地，作为一个实施例，在S102中，可以根据所述多个定位信息的重叠区域，确定所述终端的位置信息。也可理解，将多个定位信息所确定的交集，确定为终端的位置。
本发明实施例中的多种无线接入技术的定位精度不同。可将多种无线接入技术分为两类，多种无线接入技术包括第一类无线接入技术和第二类无线接入技术，其中，所述第一类无线接入技术的定位精度低于所述第二类无线接入技术的定位精度。那么，S102中，根据所述第一类无线接入技术的多个定位信息确定所述终端的大致范围；根据所述第二类无线接入技术的多个定位信息，在所述大致范围的基础上，确定所述终端的位置信息。
例如，第一类无线接入技术可以是支持连续覆盖的无线接入技术，第二类无线接入技术可以是以热点等方式部署的无线接入技术。
具体地，支持连续覆盖的无线接入技术(例如GSM/WCDMA/LTE，以及专门用于定位的无线技术)，与以热点等方式部署的无线接入技术(例如WLAN、Bluetooth、NFC、Zigbee)的定位精度可能不同。其中，以热点等方式部署的无线接入技术由于频段较高、发射功率较小、覆盖范围较小，从而定位精度较高。那么，在S102中，可以先使用连续覆盖的无线接入技术获得终端的位置的大致范围；当终端接近覆盖范围较小、定位精度较高的无线接入技术的基地台时，使用较高精度的定位信息修正终端的位置信息，从而确定终端的较为精确的位置信息。
这样，本实施例中，能够综合多种无线接入技术所获得的终端的定位信息，获得更高精度的终端的位置信息。
可理解，通过在S102中对终端在不同的时刻进行定位，可以根据与时间有关的位置信息确定终端的运动轨迹和运动速度等信息。进一步地，可以预测终端在下一时刻的可能位置；另外，还可以结合数字地图等为终端进行导航。
具体地，终端可以根据需求(例如，地图或导航软件开启)在一种或多种无线接入技术的上行数据或信令中嵌入时间标记(time stamp)，当一种或多种无线接入技术的基地台接收到包括时间标记的上行数据或信令之后，可以得到包括时间信息的定位信息。也就是说，定位信息可以包括位置区域，以及与该位置区域对应的时刻信息。
例如，在时刻1(记为t1)，终端向无线接入技术A的基地台发送嵌入时间标记的数据包；在时刻2(记为t2)，终端移动出了无线技术A的覆盖范围，向无线接入技术B的基地台发送嵌入时间标记的数据包；在时刻3(记为t3)，终端移动出了无线接入技术B的覆盖范围，向无线接入技术C的基地台发送嵌入时间标记的数据包；在时刻4(记为t4)，终端回到无线接入技术A的覆盖范围，向无线接入技术A的基地台发送嵌入时间标记的数据包。其中上述时刻的先后顺序为t1→t2→t3→t4。那么，无线接入技术A、B、C的基地台分别收到数据包后，即可判断出终端的位置和移动顺序为：t1时刻无线接入技术A的基地台的覆盖范围→t2时刻无线接入技术B的基地台的覆盖范围→t3时刻无线接入技术C的基地台的覆盖范围→t4时刻无线接入技术A的基地台的覆盖范围。
这样，在S102中，既可以确定终端的位置信息，同时，还可以结合时刻信息确定终端的运动轨迹。并且，对多种无线接入技术的定位信息的汇总可以获得更加准确和全面的终端的位置信息和运动轨迹。
可选地，作为另一实施例，在S102中，如果确定所述多种无线接入技术中的第一无线接入技术的第一定位信息存在不准确的可能性，则根据所述多个定位信息中除所述第一定位信息之外的其他定位信息确定所述终端的位置信息。
具体地，由于无线信号传输路径上的障碍物等因素(例如拐角)，同一种无线技术难以保证在整个覆盖区域内具有相同或相近的定位精度。此时，可以使用其他无线技术的定位信息进行修正。
举例来说，若第一无线接入技术的第一定位信息与其他的定位信息中的任意一个都不存在位置区域的交集，可以判断该第一定位信息不准确。进而可以不使用该第一无线接入技术进行定位。
例如，当判断某一种无线技术的定位信息可能不准确时(例如，在终端低速运动时出现位置的突然变化)，可以使用另一种或多种无线技术的定位信息进行纠偏。
具体地，可以使用多种无线接入技术中除去该第一无线接入技术的其他无线接入技术的多个定位信息确定终端的位置信息。例如，可以使用其他无线接入技术的多个定位信息的加权平均确定终端的位置信息。也就是说，可以使用其他定位信息的加权平均，确定所述终端的位置信息。这里的其他定位信息指的是其他的无线接入技术的定位信息。
可选地，作为一个实施例，若图1的方法由终端执行。那么S102中，可以结合终端的内置传感器所获取的定位信息，根据所述多个定位信息确定所述终端的位置信息。其中，终端的内置传感器可以包括以下的一种或几种：地磁计、计步器、气压计、加速度检测器等。
这样，将多种无线接入技术的多种定位信息与内置传感器的定位信息进行联合使用，可以进行相互纠错，这样能够提高定位的精确度。
进一步地，终端还可以实时跟踪多种无线接入技术的状态(如信号质量，传输速率，小区负载等)，并对未来可能的切换或技术失效作出预测。终端可以把此信息告知网络设备。这样，网络设备可以根据该预测信息进行定位的策略调整，例如，将可能将失效的无线接入技术断开连接。
本发明实施例中，通过多种无线接入技术的联合使用，或者多种无线接入技术与终端的内置传感器技术的联合使用，能够有效地提高无线系统的定位和导航的能力。并且，可以应用于室内等全球定位系统(Global Navigation Satellite System，GNSS)无法使用或性能无法满足的场景。
图2是本发明一个实施例的用于定位的设备的结构框图。图2所示的设备200包括获取单元201和确定单元202。
获取单元201，用于获取多种无线接入技术的多个定位信息，所述多个定位信息中的每个定位信息是通过对应的无线接入技术确定的，所述每个定位信息表示终端的位置区域。
确定单元202，用于根据获取单元201获取的所述多个定位信息确定所述终端的位置信息。
本发明实施例中，使用多种无线接入技术对终端进行联合定位，能够提高定位的精度，并且多种无线接入技术的联合定位的方法能够满足室内等场景。
可选地，作为一个实施例，获取单元201还可用于接收所述多种无线接入技术的基地台发送的注册信息。相应地，确定单元202可具体用于根据所述注册信息和所述多个定位信息确定所述终端的位置信息。
其中，所述注册消息可包括：所述基地台的位置信息、所述基地台的频段信息、所述基地台的发射功率、所述基地台的天线配置信息。所述基地台的位置信息可包括：所述基地台的经度信息、所述基地台的纬度信息和所述基地台的高度信息。所述基地台的天线配置信息可包括：所述天线的数量和所述天线的方位角。
本发明实施例中，图2中的设备200可以为网络设备。或者，设备200可以为定位服务器。或者，设备200可以为终端。
可选地，若设备200为终端，那么所述注册信息可以是所述基地台以广播的形式发送的。其中，所述广播消息可以是所述基地台在专用信令上发送的。
可理解，若设备200为终端，设备200还可以包括发送单元，用于向所述多种无线接入技术的基地台发送上行数据，以便所述多种无线接入技术的基地台根据所述上行数据确定所述终端的定位信息。其中，所述上行数据携带所述终端发送所述上行数据时的时刻信息。
这样，无线接入技术的基地台可以确定终端的定位信息，定位信息可以包括终端的位置范围与时刻信息的对应关系。
可选地，确定单元202可具体用于：结合所述终端的内置传感器所获取的定位信息，根据所述多个定位信息确定所述终端的位置信息。其中，内置传感器可以包括以下的一种或几种：地磁计、计步器、气压计、加速度检测器等。

可选地，作为另一个实施例，所述定位信息还包括与所述位置区域对应的时刻信息。那么，确定单元202可具体用于：根据所述多个定位信息确定所述终端的位置信息和所述终端的运动轨迹。
