Description

一种定位方法、 网络侧设备、 定位节点及定位系统 技术领域
本申请涉及通信技术领域, 尤其涉及一种定位方法、 网络侧设备、 定位 节点及定位系统。 背景技术
随着移动通信技术的发展和智能终端的普及, 移动网络业务日益丰富, 使得人们的生活更加便利。 其中, 定位服务得到了广泛的应用, 例如: 交通 导航、 地理位置检索、 位置信息分享等。 由于人们活动的大部分时间在室内,
80%的电话和数据上网业务也来自室内。 因此, 室内定位的应用也逐渐成为需 求热点, 而且业务丰富, 例如: 大型商场、 机场内的位置导航, 大型写字楼 内的房间查找, 停车位的查找、 闹市区的商铺、 人员位置检索等, 超市内的 购物导航等等, 这些应用需要更高的定位精度, 例如小于 5米甚至达到 1米以 内的定位误差, 才能获得良好的用户体验。
传统的定位月良务主要分为两类:全球定位系统( Global Positioning System; GPS )定位和运营商部署的移动蜂窝网络定位。 GPS定位的原理是: 用户终端 利用检测到的多个定位卫星, 通常 4颗以上, 在同一时间发出的信号到达的先 后顺序和时间差, 计算出用户到各个卫星之间的距离, 再根据卫星的点位, 进一步得到用户的经纬度和高程。 GPS定位在室外可以达到 10米以内的精度, 满足室外定位服务需求; 但在室内, 由于信号被阻挡, 而无法正常使用。 利 用移动蜂窝网络进行定位, 可以直接根据用户所在蜂窝小区的基站位置, 初 步确定用户的位置范围, 小区的覆盖半径越小, 得到的位置精度越高; 进一 步还可以通过测量用户到基站的距离、 到达角 (AoA )或者多小区联合测量 得到到达时间差 (OTDOA, UTDOA ), 计算出更高精度的定位结果。 目前, 第三代合作伙伴计划 ( The 3rd Generation Partnership Project; 3 GPP )标准设 计的通用移动通信系统 ( Universal Mobile Telecommunications System; UMTS ) 或长期演进( Long Term Evolution; LTE ) 系统能够达到的室外定位精度目标 为: 67%定位误差小于 50m, 95%定位误差小于 150m。 由此可见, 利用传统的 GPS和宏蜂窝网络, 室外定位的精度较低, 更无法满足室内定位精度的要求。 发明内容

N个定位节点, 用于按照该配置信息, 接收 UE 30发送的上行定位参考 信号, 并基于上行定位参考信号获得 N个测量结果, N个定位节点中的 M个 定位节点将与 M个定位节点对应的 M个测量结果发送给网络侧设备 10; 其 中, M为小于等于 N的正整数。 网络侧设备 10还用于基于 M个测量结果确 定 UE 30所在的位置。 举例来说, 确定 UE 30位于哪个节点覆盖区域, 就将 该节点覆盖区域作为 UE 30的位置。 进一步, 网络侧设备 10还用于将确定的 位置发送给 UE 30或另一网络侧设备。 如果是发送给另一网络侧设备, 那么 可以再由另一网络侧设备发送给 UE 30或其他用户设备。
请一并参考图 3 所示, 为基于该定位系统的定位方法的流程图, 该定位 方法包括:
步骤 301 : 网络侧设备 10接收一定位请求, 定位请求用于触发对 UE 30 进行定位; 并基于定位请求向 N个定位节点发送配置信息; 其中, 定位请求 可以是用户设备 UE 30发送的, 也可以是由另一网络侧设备发送的; 配置信 息用于指示 UE 30的信息和 /或 UE 30发送的上行定位参考信号的信息; 步骤 302: N个定位节点按照配置信息,接收 UE 30发送的上行定位参考 信号, 并基于上行定位参考信号获得 N个测量结果;
步骤 303: N个定位节点中的 M个定位节点将与 M个定位节点对应的 M 个测量结果发送给网络侧设备 10;
步骤 304: 网络侧设备 10基于 M个测量结果确定 UE 30所在的位置。 例 如: 确定 UE 30所在的节点覆盖区域作为 UE 30的位置。
进一步,网络侧设备 10还将确定的位置发送给 UE 30或另一网络侧设备。 其中, 在步骤 301中, 因为 UE 30有定位的需求, 所以就发送定位请求, 那么网络侧设备 10就接收 UE 30发送的定位请求。 而如果当其他服务器, 例 如社交网络服务器也需要对 UE 30进行定位时, 也可以向网络侧设备 10发送 定位请求。然后网络侧设备 10基于该定位请求向设备覆盖区域内的 N个定位 节点发送配置信息, 其中, 配置信息可以包括 UE 30的标识, 和 /或包括 UE 发送上行定位参考信号的传输配置, 例如时频资源位置、 使用的码序列、 发 射功率等。 UE 30的标识用于全球唯一或一定范围内唯一的标识 UE 30。这样, 定位节点就知道在什么样的位置上接收 UE 30发送的上行定位参考信号。
举例来说, 上行定位参考信号具体可以为: UE 30发送给网络侧设备 10 的业务信道或控制信道信号、 UE 30发送给网络侧设备 10的用于测量或信道 估计的参考信号, 或者专门定义的用于定位节点检测的上行定位参考信号。
当上行定位参考信号具体为发送给网络侧设备 10的业务信道或控制信道 信号或 UE 30发送给网络侧设备 10的用于测量或信道估计的参考信号时,UE 30的资源调度由 UE 30和网络侧设备 10之间的通信需求决定, 而跟 UE 30 是否请求定位无关, 所以有可能在 N个定位节点接收到配置信息之前, UE 30 的信号发送已经配置好,这时网络侧设备 10不需要再次向 UE发送配置信息。 而当上行定位参考信号具体为专门定义的用于定位节点检测的上行定位参考 信号, 那么网络侧设备 10还要向 UE 30发送相同的配置信息。 因此, 综上, 当在 N个定位节点接收到配置信息之前, UE 30未收到相同的配置信息, 那 么网络侧设备 10还向 UE 30发送相同的配置信息。
然后 UE 30按照收到的配置信息发送上行定位参考信号,所以在步骤 302 中, N个定位节点按照配置信息, 接收 UE 30发送的上行定位参考信号, 并 基于上行定位参考信号获得 N个测量结果。 其中, 基于上行定位参考信号获 得 N个测量结果, 具体有多种实施方式, 第一种, 定位节点检测上行定位参 考信号的接收信号功率, 判断该功率是否超过预定的功率门限, 当该功率超 过预定的功率门限时, 则表示 UE 30位于该定位节点的节点覆盖区域内, 反 之, 则表示 UE 30不在该定位节点的节点覆盖区域内; 因此, 在该种情况下, 测量结果具体可以为表示 UE 30位于或没有位于该定位节点的节点覆盖区域 内的结果。 第二种, 就是直接将检测得到的接收信号功率作为测量结果。
接下来执行步骤 303 ,即 N个定位节点中的 M个定位节点对应的 M个测 量结果发送给网络侧设备 10。 在实际运用中, 根据测量结果的不同, 上报测 量结果的 M个定位节点也跟着发生变化, 例如: 当测量结果为表示 UE 30位 于或没有位于该定位节点的节点覆盖区域内的结果时, 只有测量结果为 "是" 的定位节点才发送测量结果给网络侧设备 10, 请参考图 1和图 2所示, 假设 定位节点 201的测量结果为是, 即 UE 30位于定位节点 201的节点覆盖区域 2011内, 而定位节点 202的测量结果为否, 即 UE 30没有位于定位节点 202 的节点覆盖区域 2022 内, 那么定位节点 201就将测量结果 "是", 或者用其 他符号表示, 例如 "1" 发送给网络侧设备 10, 而定位节点 202则不发送。
再例如: 当测量结果为上行定位参考信号的接收信号功率时, N个定位 节点中的所有定位节点均将自身测量的接收信号功率发送给网络侧设备; 或 者只有接收信号功率超过预定的功率门限的定位节点才发送自身测量的接收 信号功率给网络侧设备 10, 而接收信号功率未超过预定的功率门限的定位节 点则不发送测量结果。
然后执行步骤 304,即网络侧设备 10基于 M个测量结果确定 UE 30所在 的节点覆盖区域, 并将 UE 30所在的节点覆盖区域作为 UE 30的位置。
进一步, 网络侧设备还将确定的位置发送给 UE 30或另一网络侧设备。 如果是发送给另一网络侧设备, 那么再由另一网络侧设备发送给 UE 30或其 他用户设备。
类似的,根据接收的测量结果的不同, 网络侧设备 10基于 M个测量结果 确定 UE 30所在的位置, 也有不同的实施方式, 例如: 对应前述第一种的测 量结果, 因为测量结果为表示 UE 30位于 M个定位节点的节点覆盖区域内的 结果, 所以网络侧设备 10基于 M个测量结果确定 UE 30所在的节点覆盖区 域,具体为:基于 M个测量结果确定 UE 30所在的节点覆盖区域为 M个定位 节点的节点覆盖区域的交界位置。在本实施例中,分两种情况: 第一, M为 1 , 即只有一个定位节点上"¾了测量结果, 那么就确定 UE 30位于该一个定位节 点的节点覆盖区域内, 因为只有一个节点覆盖区域, 所以节点覆盖区域的交 界位置即为节点覆盖区域本身; 在这种情况下, 由于一个定位节点的节点覆 盖区域较小, 通常半径小于 5m, 所以将该节点覆盖区域作为 UE 30的位置的 位置精度较高。 第二, M大于 1 , 即有多个定位节点上报测量结果 "是", 所 以确定这多个定位节点的节点覆盖区域的交界位置为 UE 30所在的节点覆盖 区域, 进一步, 将该交界位置作为 UE 30所在的位置, 这样定位的精度就更 高。
对于另一网络侧设备而言,接收到网络侧设备 10发送的 UE 30的位置后, 可以将 UE 30的位置发送给 UE 30,使得在社交网络的客户端上显示出 UE 30 的位置。 还可以是发送给其他用户设备。
当测量结果为接收信号功率时, 网络侧设备 10基于 M个测量结果确定 UE 30所在的节点覆盖区域,具体为:基于 M个接收信号功率通过计算 UE 30 到 M个定位节点之间的距离, 确定 UE所在的节点覆盖区域。
类似的, 在本实施例中, 分为三种情况: 第一, M为 1 , 即只有一个定位 节点上报时, 则根据接收信号功率和 UE 30的发射信号功率的差别, 计算出 上行参考定位信号的传播距离, 该距离即为 UE 30和定位节点之间的距离, 可以实现在定位节点的节点覆盖区域内的进一步定位, 例如: 该定位节点的 节点覆盖区域的半径为 5m, 但是通过计算, 确定出 UE 30距离该定位节点 的距离为 2m,那么就可以确定 UE 30的位置为该节点覆盖区域的半径 2m之 内的区 i或。
第二, M大于 1 , 即有多个定位节点上报接收信号功率, 且这些上报的接 收信号功率大于预定的功率门限, 即表示 UE 30同时位于这多个定位节点的 节点覆盖区域内, 也就是说 UE 30位于这多个定位节点的节点覆盖区域的交 界位置, 然后分别计算 UE 30到每个定位节点之间的距离, 可以在该交界位 置进一步缩小 UE 30的位置, 所以定位精度更高。
第三, M等于 N, 即所有定位节点都上报了接收信号功率, 这些上报的 接收信号功率有些超过预定的功率门限, 其余的未超过预定的功率门限, 那 么网络侧设备 10先进行判断, 然后可以只考虑超过预定的功率门限, 按照 前面第二中描述的方法确定 UE 30的位置。 或者网络侧设备 10不判断与预 定的功率门限之间的关系, 而是选择接收信号功率最高的前几个的定位节 点,结合 UE 30到定位节点的距离和这几个定位节点的交界位置,确定 UE 30 的位置。
当测量结果为接收信号功率时, 网络侧设备 10基于 M个测量结果确定 UE 30所在的节点覆盖区域, 具体为: 确定最高的接收信号功率对应的定位 节点的节点覆盖区域为 UE 30所在的位置。 具体来说, 将接收到的接收信号 功率进行排序, 确定出最高的接收信号功率, 就将最高的接收信号功率对应 的定位节点的节点覆盖区域为 UE 30所在的节点覆盖区域。 其中, 接收到的 接收信号功率可以是部分定位节点发送的, 也可以是全部定位节点发送的; 接收到的接收信号功率可以全部都超过预定的功率门限, 也可以有些超过预 定的功率门限, 其余的未超过预定的功率门限。
当将 UE 30的位置确定出来之后, 网络侧设备 10就将确定出的位置发送 给 UE 30, UE 30接收到之后, 就可以在应用中体现出自身的位置, 例如在导 航地图上用图标显示 UE 30当前的位置。
进一步, 在实际运用中, 在步骤 302中, N个定位节点还测量 UE 30发 送的上行定位参考信号到自身的到达角 (AoA ), 将到达角也作为测量结果, 并在步骤 303中上报给网络侧设备 10,那么网络侧设备 10在步骤 304中也可 以结合到达角确定 UE 30的位置, 进一步缩小 UE 30在定位节点的节点覆盖 区域内的范围。
其中,在以上各实施例中,网络侧设备 10向 N个定位节点发送配置信息, 以及 N个定位节点向网路侧设备 10上报测量结果,具体可以是通过空口通信 协议进行传输, 其中空口通信协议例如为蜂窝通信系统中的空口通信协议; 或者 WiFi或蓝牙协议。 蜂窝通信系统中的空口通信协议具体例如为: 机器对 机器( Machine to Machine; M2M ) 业务的空口通信协议, 如 3GPP定义的低 成本机器类通信( Machine type Communication; MTC )空口通信协议, 例 ^口: 全球移动通信 ( Global System for Mobile Communications; GSM )系统、 通用 移动通信系统 ( Universal Mobile Telecommunications System; UMTS )、 长期 演进(Long Term Evolution; LTE ) 系统中的空口通信协议。 如 GSM系统中 的通用无线接入网 GRAN协议。
进一步, 定位节点与网络侧设备 10之间传输的数据包较小, 所以可以不 需要大流量、 高速率传输, 因此就可以利用 M2M业务的空口通信协议或者可 以利用 WiFi或蓝牙直连等方式进行传输。因此,定位节点具体为特定的 M2M 终端,例如在蜂窝网或无线局域网中的 M2M终端上增加接收和检测 UE上行 定位参考信号的功能和模块(可包括天线, 射频感知器件等), 即可作为定位 节点。
而定位节点和 UE 30之间,定位节点按照 UE 30与网络侧设备 10使用的 通信协议接收上行定位参考信号。
在另一实施例中, 定位节点也可以为蜂窝网络中具备设备对设备( Device to Device; D2D )通信功能的终端, 则网络侧设备 10与定位节点之间的通信 釆用蜂窝系统的上下行空口通信协议,而定位节点与 UE 30之间可以釆用 D2D 通信方式实现定位节点对 UE发射的上行定位参考信号的测量。 当然,在本实 施例中, 定位节点也可以按照 UE 30与网络侧设备 10使用的通信协议接收上 行定位参考信号。 在本申请实施例中, 网络侧设备 10与定位节点之间由于釆用了空口通信 协议, 使得定位节点的布放非常灵活, 大大降低了部署复杂度。 进一步, 本 申请实施例中各网元之间的通信均为重用现有通信标准,对 UE无影响, 而定 位节点的实现简单, 成本低, 而网络侧改动也少。 再进一步, 如果釆用 M2M 终端作为定位节点, 由于其专门为小数据包传输而设计, 压缩了设备成本, 而且功率消耗低。
而对于定位节点的供电, 可以有多种解决方案:
第一, 部署于电源接口附近, 例如, 现有插座旁边, 灯箱内。
第二, 无线充电: 利用无线充电技术, 持续通过空间电磁信号感应, 进 行充电。
第三, 太阳能、 可见光充电。
第四, 人工更换电池, 网络侧设备 10可以获得定位节点的发送功率资源 池 PHR ( Power Headroom ), 判断是否需要更换电池。
接下来请参考图 4 所示, 为本实施例中基于蜂窝网的定位方法的一个具 体实例, 其中, 定位请求由 UE 30触发 , 网路侧设备 10以基站为例 , 该定位 方法包括:
步骤 1 : UE发送定位请求给基站, 例如 UE对应的用户在发微博时, 用 户选择了 "插入位置", 那么这时 UE就会向基站发送定位请求。
步骤 2: 基站在接收到该定位请求之后, 就向定位节点发送配置信息, 该 配置信息包括 UE的唯一标识, 还有 UE发送上行定位参考信号的传输配置。
步骤 3: 基站向 UE发送发送上行定位参考信号的传输配置, 此步骤为可 选, 因为如果上行定位参考信号具体为 UE发送给基站的业务信道、控制信道 信号或测量、 信道估计等参考信号不是专用于定位节点检测的信号时, 其资 源调度由 UE与基站之间的通信需求决定,所以有可能在定位节点收到配置信 息之前 UE的信号发送已经配置好, 则基站不需要再次向 UE发送配置信息, 换言之, 步骤 3并不是在每次定位流程中都必须执行。
步骤 4: UE向定位节点发送上行定位参考信号, 具体来说, UE根据基 站发送的传输配置发送上行定位参考信号。
步骤 5: 定位节点根据配置信息接收上行定位参考信号, 并测量上行定位 参考信号, 例如测量接收到的上行定位参考信号的接收信号功率, 和 /或到达 角。
步骤 6: 定位节点上报测量结果给基站, 具体例如通过空中通信协议向基 站上报测量结果。
步骤 7: 基站根据测量结果确定 UE的位置, 具体确定出来的位置为某个 定位节点的节点覆盖区域内, 或者是某几个定位节点的节点覆盖区域的交界 位置。
步骤 8: 基站将 UE的位置反馈给 UE, 那么 UE的位置就可以体现在 UE 上, 例如在写新微博的界面上显示用户的位置为 "XX商场二楼 XX餐厅"。
其中, 在步骤 1之后, 步骤 3之前, 基站还向定位节点发送触发信息, 触发定位测量, 此时定位节点才进入定位测量过程; 对应的, 在步骤 8之后, 基站还向定位节点发送关闭信息, 关闭定位测量。 因此, 通过本实施例的方 法, 定位节点在没有测量任务时, 可以进入休眠状态, 在有测量任务时, 由 基站将其唤醒, 如此可以降低定位节点的功耗。

其中, 在步骤 404中, 当 M个测量结果具体为表示 UE位于 M个定位节 点的节点覆盖区域内的结果时, 网络侧设备基于 M个测量结果确定 UE所在 的位置, 具体为: 当 M大于 1时, 确定 M个定位节点的节点覆盖区域的交界 位置为所述 UE所在的位置; 当 M等于 1时, 确定 M个定位节点的节点覆盖 区域为 UE所在的位置。
而当 M个测量结果具体为上行定位参考信号的接收信号功率时, 网络侧 设备基于 M个测量结果确定 UE所在的位置, 具体为: 基于 M个接收信号功 率通过计算 UE到 M个定位节点之间的距离, 确定 UE所在的位置; 或, 确 定最高的接收信号功率对应的定位节点的节点覆盖区域为 UE所在的位置。

本申请实施例中提供的一个或多个技术方案, 至少具有如下技术效果或 优点:
在本申请实施例中, 在网络侧设备的覆盖范围内, 再部署至少一个定位 节点, 每个定位节点覆盖更小的区域, 定位节点基于网络侧设备发送的配置 信息接收用户设备 UE发送的上行定位参考信号,并根据该上行定位参考信号 获得测量结果, 然后将测量结果上报给网络侧设备, 由网络侧设备根据定位 节点上报的测量结果确定用户设备 UE 的位置位于哪个定位节点的覆盖区域 内, 所以本申请实施例中的定位方法在网络侧设备的覆盖范围内能够获得更 小范围的定位, 所以定位精度相比传统的 GPS定位和宏蜂窝网络的定位精度 提高了; 进一步, 通过改变定位节点的覆盖区域的大小, 可以满足各种精度 的需求, 所以可以根据实际的精度需求灵活的进行网络部署。
