Description

定位方法、定位装置及基站 技术领域
本发明涉及通信技术领域，尤其涉及一种定位方法、定位装置及基站。
背景技术
信息化时代，人们早已不满足于仅限于人与人的通信，物联网(Internet of Things，IoT)技术应运而生，并且发展迅速。窄带物联网(Narrow Band Internet of Things，NB-IoT)是IoT领域一个新兴的技术，支持低功耗设备在广域网的蜂窝数据连接。下行到达时间观测差(Observed Time Difference of Arrival，OT-DOA)定位是一种控制面定位(Control Plane，CP)方法，可应用于各种移动通信***。第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)版本(Release)14的标准中，增加定位的特性，已经同意支持NB-IoT OT-DOA定位。OT-DOA定位可以在连接态也可以在空闲态时进行。
通常地，若空闲态终端设备接收到定位服务器发送的请求位置信息后，获知需要进行定位测量以及上报位置信息，但是因为定位服务器发送的消息是通过长期演进定位协议(Long Term Evolution Positioning Protocol，LPP)层传输的，基站并不知道，如果没有任何指示消息，终端设备只能等待网络侧的非激活计时器(inactivity timer)超时后，网络侧释放终端设备进入空闲态，终端设备才能进行测量，测量完成后进行上报。在这种情况下，由于网络侧不能及时释放终端设备进入空闲态，因此无法及时进行定位，将出现时延问题。
另外，对于空闲态终端设备，一种可行的进行OT-DOA定位的具体流程是：当终端设备接收到定位服务器发来的LPP消息(例如OT-DOA请求位置信息)，终端设备收到请求后，通过无线资源控制(Radio Resource Control，RRC)消息(例如参考信号时间差(Reference Signal Time Difference，RSTD)测量指示消息)请求进入空闲态，基站接收到该消息后，将发送RRC连接释放消息给终端设备，终端设备进入空闲态开始测量，当测量完成后，终端设备发起随机接入请求(Random Access Channel，RACH)，并通过LPP层消息(例如OT-DOA提供位置信息消息)，将测量结果发送给定位服务器。该方案缺点是使用CP方案的终端设备无空口安全保护，不适合增加RRC消息，因而无法引入RSTD测量指示消息。
通常地，对于连接态终端设备，进行OT-DOA定位流程如下：首先，终端设备收到定位请求后，向基站发送RRC消息(例如RSTD测量指示消息)，以请求测量配置信息(例如测量的频点及其测量时间间隔(gap)的偏置量(offset))。然后，基站向终端设备发送RRC重配置连接消息，该消息携带有测量配置信息。终端设备接收该消息后，向基站发RRC重配置完成消息，并开始执行测量。当终端设备进行完定位测量，并将测量结果通过LPP消息上报后，向基站发送RRC消息，进行停止定位指示。该方案的缺点是现有的用于测量请求和测量配置的相关RRC消息都是有接入层(Access Stratum，AS)安全的，而 使用CP方案的终端设备因没有AS安全，不适合增加与测量请求和测量配置相关的RRC消息。
综上，现有技术包括空闲态和连接态OT-DOA定位，所存在的缺点是，对于空闲态如果通过网络侧非激活计时器(inactive timer)溢出再进行空闲态测量，不能及时进行定位测量，有时延影响。对于空闲态或连接态，终端设备在向基站请求测量配置信息时，均需要引入RRC消息，对于使用CP方案的终端设备因没有AS安全，不支持增加与测量请求和测量配置相关的RRC消息而无法实现，并且空口传输还会增加功耗。
