下面以具体地实施例对本发明的技术方案进行详细说明。 下面这几个 具体的实施例可以相互结合, 对于相同或相似的概念或过程可能在某些实 施例不再赘述。
通常一个无线接入设备会接入 M个移动终端, M≥l, 上述 M个移动 终端通过无线接入设备接入互联网, 当 M等于 1时, 如图 1所示, 图 1 为本发明的系统一的架构图, 当M>1时, 如图 2所示, 图 2为本发明的 系统二的架构图, 即多个移动终端通过同一个无线接入设备接入互联网。
图 3为本发明的无线接入服务方法实施例一的流程示意图, 如图 3所 示, 本实施例的执行主体是无线接入设备, 本实施例的无线接入设备具有 自移动功能, 可通过机器人来实现, 本实施例的应用场景是接入无线接入 设备的移动终端中, 具有一个特定的移动终端, 例如: 特定的移动终端可 以是运营商的一个重要人物 (Very Important Person, 以下简称: VIP) , 运营商一般会考虑优先满足这种特定的移动终端的通信质量需求。 为了便 于描述, 图 3所示实施例中, "单个移动终端的通信质量需求"是指该特 定的移动终端的通信质量需求, "移动终端"是指该特定的移动终端, 而 不是接入无线接入设备的所有移动终端, 本实施例的方法如下:
S301 : 无线接入设备检测第一无线接入链路的质量是否满足单个移动 终端的通信质量需求。
其中, 第一无线接入链路为无线接入设备在当前位置到移动终端之间 的无线接入链路。
无线接入设备可以周期性的广播自己的存在, 从而保证有移动终端发现 该无线接入设备后通过无线方式接入到本无线接入设备。
第一无线接入链路的质量可以通过以下两种方式但不限于以下两种方式 获知, 第一种方式, 无线接入设备定时检测获知; 具体地, 无线接入设备设 置一定周期的定时器, 当定时器到期时, 则获取表征第一无线接入链路的质 量的参数, 其中, 可以用来表征第一无线接入链路的质量的参数可以是: 移 动终端到无线接入设备之间的接收信号强度指示 (Received Signal Strength Indication, 简称: RSSI) 信息、 移动终端用户的接入速率、 带宽信息或者移 动终端的业务类型等; 第二种方式: 也可以通过移动终端定时上报参数的方 式获知第一无线接入链路的质量。
单个移动终端的通信质量需求可以包括下述至少一种: RSSI强度不低于 RSSI阈值; 或者, 接入速率不低于接入速率阈值; 或者, 接入带宽不低于接 入带宽阈值; 其中 RSSI强度、接入速率、接入带宽可以是针对当前业务类型 的, 具体为: 移动终端的当前业务类型下的 RSSI不低于上述当前业务类型所 需求的 RSSI阈值,或者, 上述移动终端的当前业务类型下的接入速率不低于 上述当前业务类型所需求的接入速率阈值, 或者, 上述移动终端的当前业务 类型下的接入带宽不低于上述当前业务类型所需求的接入带宽阈值。
下面, 以移动终端的通信质量需求为 RSSI强度不低于 RSSI阈值为例进行 说明, 当无线接入设备检测到的第一无线接入链路的 RSSI低于 RSSI阈值时, 则确定第一无线接入链路的质量已经不能满足移动终端的通信质量需求。 其 他通信质量阈值设置类似, 在此不再赘述。
上述定时检测或定时上报第一无线接入链路的质量, 无线接入设备可以 在本地通过定时器实现, 例如, 无线接入设备本地设置时间为 lmm的定时器, 则无线接入设备每隔 1分钟会检测一下当前的无线接入链路是否满足移动终 端的通信质量需求。 无论在无线接入设备静止不动还是移动时该定时器都会 定时触发无线接入链路的质量检测。
需要说明的是, 定时检测或定时上报只是一种实现方式, 本发明还可以 根据实际需要, 采用其他的方式检测, 本发明对此不作限制。
S302: 当无线接入设备判断第一无线接入链路的质量不满足单个移动 终端的通信质量需求时, 上述无线接入设备开始移动。
§卩, 无线接入设备静止不动时, 检测到第一无线接入链路不满足单个 移动终端的通信质量需求, 则触发无线接入设备开始移动, 检测到无线接 入链路满足移动终端的通信质量需求, 则继续保持当前状态。
S303 : 无线接入设备在移动过程中, 无线接入设备检测第二无线接入 链路的质量是否满足单个移动终端的通信质量需求, 若满足, 执行 S304, 若不满足, 执行 S305。
其中, 第二无线接入链路为无线接入设备在移动后的位置与移动终端 之间的无线接入链路。
S304 : 无线接入设备停止移动。
S305 : 无线接入设备继续移动。
其中, 无线接入设备继续移动的过程中, 执行 S303。
也就是, 当无线接入设备处于移动过程中, 检测到第二无线接入链路 满足单个移动终端的通信质量需求, 则无线接入设备停止移动, 检测到第 二无线接入链路不满足单个移动终端的通信质量需求, 则无线接入设备继 续移动。 其中, 在移动过程中, 无线接入设备检测第二无线接入链路的质 量是否满足单个移动终端的通信质量需求, 可以是, 无线接入设备设置周 期性检测定时器, 当定时器到期时, 启动检测第二无线接入链路的质量是 否满足单个移动终端的通信质量需求, 该方法与检测第一无线接入链路的 质量是否满足单个移动终端的通信质量需求的方法类似, 在此不再赘述。
在无线接入设备继续移动的过程中执行 S303 ,直到无线接入设备与移 动终端之间的第二无线接入链路的通信质量能够满足单个移动终端的通 信质量需求时, 停止移动。
当无线接入设备确定要通过无线接入设备开始移动或继续移动的方式来 满足单个移动终端的通信质量需求之后, 首先要获取移动的目标方向, 无线 接入设备沿着目标方向移动。
具体地, 确定目标方向的实现方式包括但不限于下述方式, 其中一种实 现方式是无线接入设备根据无线接入链路的参数确定目标方向, 上面所提到 的无线链路的参数可以是无线链路的当前时刻的参数, 也可以是无线接入链 路当前时刻及当前时刻之前的参数。 上面所说的无线接入设备通过开始移动 或继续移动的方式来满足移动终端的通信质量需求, 其中, 开始移动指的是 原来静止状态, 需要通过移动来使得无线接入链路的质量改善; 继续移动指 的是已经在移动了, 但是仍然需要继续移动来使得无线接入链路质量进一歩 改善。 上述两种情况, 都需要确定移动的目标方向。 在本实施例中, 将无线 接入设备第一次移动的目标方向, 称为第一目标方向, 也就是无线接入设备 的状态从静止转为移动的过程中确定的目标方向; 无线接入设备在移动过程 中, 可能会根据对第二无线接入链路的质量的检测结果重新确定目标方向, 重新确定的目标方向称为第二目标方向, 也就是无线接入设备在移动过程中 确定的目标方向。 其中, 第一目标方向与第二目标方向可能相同, 也可能不 同, 但是确定第一目标方向和第二目标方向的方法相同, 即都是根据无线接 入设备与移动终端之间的无线接入链路的参数确定的, 确定第一目标方向是 根据第一无线接入链路的参数确定的, 确定第二目标方向是根据第二无线接 入链路的参数确定的。
下面详细介绍确定第一目标方向的过程:
第一歩: 无线接入设备获取第一无线接入链路的参数。
其中, 第一无线接入链路的参数可以是第一无线接入链路上传输的信号 的参数和 /或与第一无线接入链路相关的天线的参数和 /或与无线接入链路相 关的移动终端的位置信息等, 其中, 第一无线接入链路上传输的信号的参数 包括: 无线信号的强度、 方向、 时延、 根据到达时间 (Time Of Arrival, 以下简称: T0A)、 到达方位角 (Angle Of Arrival, 以下简称: A0A) 等; 与 第一无线接入链路相关的天线的参数包括: 通过第一无线接入链路传输信号 的移动终端接入无线设备的天线的波束的方向; 与第一无线接入链路相关的 移动终端的位置信息包括移动终端的经纬度位置等。
无线接入设备获取第一无线接入链路的参数, 可以是当前位置当前时刻 的第一无线接入链路参数, 也可以是第一无线接入链路在一定时间范围内的 参数。 例如: 几分钟前到当前时刻的第一无线接入链路的参数。
无线接入设备获取第一无线接入链路的参数, 可以通过主动收集的方式 获取, 也可以通过移动终端反馈的方式获取, 对此, 本发明不作限制。
第二歩:无线接入设备根据第一无线接入链路的参数确定第一目标方向。 本发明包括但不限于下述几种确定第一目标方向的方式:
第一种实现方式, 无线接入设备根据所述第一无线接入链路的参数获取 所述移动终端相对所述无线接入设备的方向; 所述无线接入设备确定所述移 动终端相对所述无线接入设备的方向为第一目标方向, 其中, 方向可以根据 移动终端相对无线接入设备的位置信息中的方向确定, 或者, 根据移动终端 的坐标与无线接入设备坐标之前的连线确定。本发明对获取移动终端相对无线 接入设备的方向的方法不作限制。 第二种实现方式, 常常应用于无线接入设备具有智能天线的场景, 以智 能天线中的定向天线为例进行说明, 定向天线是指在某一个或某几个特定方 向上发射及接收电磁波特别强, 而在其它的方向上发射及接收电磁波则为零 或极小的一种天线。 当采用定向天线来发射信号后, 就可以把信号的发射区 域从一个圆形缩小到一个扇形, 这样就可以根据天线波束方向确定移动终端 相对于无线接入设备的方向, 提高定位精度。 具有定向天线的无线接入设备, 可以将基于信号强度的方法与无线信号的定向特征结合起来, 再根据无线接 入设备和天线波束方向的映射, 得到移动终端相对于无线接入设备的方向, 从而确定第一目标方向, 通常, 第一目标方向为移动终端相对于无线接入设 备的方向。 如表 1所示, 表 1为无线接入设备的波束与相对于无线接入设备的 方向的映射表:
表 1为无线接入设备的波束与相对于无线接入设备的方向的映射表
Figure imgf000020_0001
以上表为例, 若移动终端通过无线接入设备的天线波束 1接入无线网络, 则可以确定移动终端在相对于无线接入设备的正东方向; 若移动终端通过无 线接入设备天线波束 2接入无线网络,则可以确定移动终端在相对于无线接入 设备的正东偏南 30°方向, 即移动终端相对于无线接入设备的方向可以通过其 接入无线网络的无线接入设备的天线波束确定。 可以理解的是, 无线接入设 备中会存储移动终端当前是通过哪个波束接入无线网络的。 为了便于理解, 本发明还给出了定向天线波束或覆盖扇区定位移动终端的示意图, 如图 4所 示, 图 4为本发明定向天线波束定位移动终端的示意图, 其中, 每个天线波束 对应一个方向。 天线波束越多, 每个天线波束对应的扇区越小, 定位的方向 越精确。
当然, 也可以结合实际环境中的障碍物信息调整第一目标方向。 采用第二种实现方式获取移动终端相对于无线接入设备的方向, 从而确 定第一目标方向, 易于实施、 节省开销、 且可用于室内大范围的高精度的定 位。
第三种实现方式以应用于无线接入设备具有多天线阵列场景为例, 但不 限于这种场景, 无线接入设备根据移动终端到天线阵列中的两个天线的到达 角确定移动终端相对无线接入设备的方向, 然后, 无线接入设备确定所述移 动终端相对所述无线接入设备的方向为第一目标方向。
下面以确定一个移动终端相对无线接入设备的方向为例进行说明。
具体地, 根据移动终端分别到天线阵列中的两个天线的到达角确定移动 终端相对无线接入设备的方向, 由于无线通信中移动终端和无线接入设备周 围的散射环境不同, 使得多天线系统中不同位置的天线经历的衰落不同, 从 而产生角度色散, 即空间选择性衰落。 因此, 随着智能天线和多输入多输出 多输入多输出 (Multiple Input Multiple Output, 以下简称: MIMO) 系统的引 入, 信道信息从原来的二维信息 (时间、 频率), 扩充到三维信息 (时间、 频 率、 空间), 因此, 与单天线的研究不同, 在对多天线的研究中, 室内定位可 以充分利用诸如 AOA、 离开方位角 (Angle Of Departure, 以下简称: AOD) 之类的空间角度的信息。 针对无线局域网 (Wireless Local Access Network, 简称: WLAN) 系统, 无线接入设备多天线阵列配置已经越来与越普遍, 因 此可以通过多天线的 AOA、 TOA和到达时间差 (Time Difference of Arrival, 以下简称: TDOA) 参数进行移动终端的定位。 基于 TDOA技术的定位算法, 在高斯噪声环境下能取得较好的定位精度。随着智能天线阵在基站中的使用, 当无线接入设备与移动终端之间为视距 (LOS)环境时,基站能够测得比较精确 的 AOA值, 利用 TDOA与 AOA的混合定位方法, 定位精度比只用 TDOA定位 方法进一歩提高。
以利用两个天线的 AOA进行定位为例进行描述,图 5为本发明利用两个天 线的 AOA进行定位的示意图, 如图 5所示, 天线 1、天线 2和移动终端三个点分 别为三角行的三个顶点, 坐标分别为 (χι, y , ( χ 2, ^ ), (χ™, ^ ), 天线
1和移动终端之间的边长为 天线 2和移动终端之间的边长为 ^, 其中, ^和 ^可以通过根据 TOA确定移动终端相对无线接入设备的距离。 移动终端的坐 标 (χ™, 则可以根据如下两个公式获得:
Figure imgf000022_0001
Figure imgf000022_0002
Figure imgf000022_0003
针对第三种实现方式, 当无线接入设备检测到多个 AOA时, 具体采用哪 两个 AOA进行计算, 可以进一歩通过传感器获取环境信息, 以确定哪个 AOA 是直接从移动终端过来的, 哪个 AOA是通过障碍物反射过来的, 通过障碍物 反射的情况如图 6所示, 图 6为本发明中通过障碍物反射的 AOA的示意图, 通 过删除通过障碍物反射过来的干扰 AOA方向, 准确估计移动终端相对无线接 入设备的方向, 从而, 确定第一目标方向, 通常, 确定移动终端相对无线接 入设备的方向为第一目标方向, 当然, 也可以结合实际环境中的障碍物信息 调整第一目标方向。
类似的, 还可以用 TOA和 TDOA, 以及上述多种无线信号统计特性联合 来做移动终端的定位。基本做法就是基于 TOA、到达方向 (Direction Of Arrival, 以下简称: DOA:)、 接收信号强度 (RSS)等参数求解几何方程的定位方法或是 几种参数的联合定位移动终端的位置。 详细的求解过程, 此处不再赘述。
可选地, 在根据第一无线接入链路参数确定第一目标方向时, 还可以结 合无线接入设备和移动终端所处的环境, 确定出更为准确可行的目标方向。 也可以在根据第一无线接入链路参数确定第一目标方向之后, 再根据无线接 入设备和移动终端所处的环境, 对上述第一目标方向进行调整, 并将调整后 的方向作为第一目标方向。 gp, 无线接入设备采用传感器感知所述无线接入 设备和所述移动终端所处的环境中的障碍物信息, 根据所述传感器感知的障 碍物信息构造所述无线接入设备和所述移动终端所处的环境; 所述无线接入 设备根据所述无线接入设备和所述移动终端所处的环境调整所述第一目标方 向。
具体地, 当根据第一无线接入链路参数确定了移动终端相对无线接入设 备的方向之后, 如果无线接入设备本地具有无线接入设备和移动终端所处环 境的全局详细地图 (也可以外部输入), 则可以直接根据自身的位置、 感知到 的障碍物和地图上标识的障碍物信息、 根据最短距离等路径规划原则, 确定 需要移动的目标方向。
如果无线接入设备本地不具有无线接入设备与移动终端所处环境的全局 详细地图, 则可以先获取无线接入设备与移动终端所处的环境。 无线接入设 备可通过采用传感器感知无线接入设备与移动终端所处的环境中的障碍物信 息,根据传感器感知的障碍物信息构造无线接入设备与移动终端所处的环境。 具体地, 无线接入设备根据传感器感知障碍物的信息, 在平面图上抽取出障 碍物的质心作为顶点, 基于沃罗诺伊图 (Voronoi) 理论, 采用近似构造法, 构造一般环境的 Voronoi图,即相当于模拟了无线接入设备与移动终端之间的 环境。 如图 7所示, 图 7为本发明的无线接入设备通过传感器感知构造的环 境示意图, 图中各圆圈即为本发明无线接入设备的传感器感知的障碍物。
可选的, 如前面上述, 当无线接入设备移动过程中, 定时器到期后检测 到第二无线接入链路的质量不满足移动终端的通信质量需求, 则会继续移 动, 继续移动过程中, 可能需要重新确定目标方向, 即第二目标方向。
具体地, 当第二无线接入链路的质量不满足单个移动终端的通信质量需 求时, 上述无线接入设备根据上述第二无线接入链路的参数确定第二目标方 向; 上述无线接入设备沿上述第二目标方向移动;
其中, 上述无线接入设备根据上述第二无线接入链路的参数确定第二目 标方向, 包括以下几种实现方式:
第一种: 无线接入设备根据所述第二无线接入链路的参数获取所述移动 终端相对所述无线接入设备的方向; 所述无线接入设备确定所述移动终端相 对所述无线接入设备的方向为第二目标方向。
第二种: 上述无线接入设备根据上述移动终端接入上述无线接入设备的 天线波束的方向确定上述第二目标方向。
第三种: 所述无线接入设备根据所述移动终端到所述无线接入设备的天 线阵列中的两个天线的到达角确定所述移动终端相对所述无线接入设备的方 向; 所述无线接入设备确定所述移动终端相对所述无线接入设备的方向为第 二目标方向。
在确定了第二目标方向之后, 在无线接入设备继续移动之前, 无线接入 设备还可以采用传感器感知所述无线接入设备和所述移动终端所处的环境中 的障碍物信息, 根据所述传感器感知的障碍物信息构造所述无线接入设备和 所述移动终端所处的环境; 所述无线接入设备根据所述无线接入设备和所述 移动终端所处的环境调整所述第二目标方向。
上述第二目标方向的确定方法, 可以参照第一目标方向的确定方法, 在 此不再赘述。
需要说明的是, 当第二无线接入链路的质量不满足移动终端的通信质量 需求时, 在无线接入设备继续移动的过程中, 是否需要重新确定移动的目标 方向, gp, 是继续按第一目标方向继续移动, 还是确定一个第二目标方向, 按照第二目标方向移动。 可以按照下述方式确定, 无线接入设备判断最近的 N次检测第二无线接入链路的质量结果中, 后一次检测结果比前一次检测结 果差的次数是否大于等于阈值, 若是, 所述无线接入设备根据所述第二无线 接入链路的参数确定第二目标方向; 若否, 无线接入设备沿着第一目标方向 继续移动。
本发明实施例, 通过无线接入设备检测第一无线接入链路的质量是否满 足单个移动终端的通信质量需求, 若无线接入设备判断第一无线接入链路的 质量不满足单个移动终端的通信质量需求, 则无线接入设备从当前位置开始 移动, 移动过程中, 可以检测第二的无线链路是否满足单个移动终端的通信 质量需求, 如果满足, 则停止移动, 如果不满足, 继续移动, 即通过无线接 入设备的移动提高无线接入链路的质量, 以满足单个移动终端的通信质量需 求。
图 8为本发明的无线接入服务方法实施例二的流程示意图, 如图 8所 示, 本实施例的执行主体是无线接入设备, 本实施例的无线接入设备具有 自移动功能, 可通过机器人实现, 本实施例的方法如下:
S801 : 无线接入设备检测第一组无线接入链路的质量是否满足移动终 端集合的通信质量需求。
其中, 第一组无线接入链路包括 R条第一无线接入链路, 上述第一无 线接入链路为无线接入设备在当前位置到 R个移动终端中的任一移动终 端之间的无线接入链路, 其中, R个移动终端为接入无线接入设备的 M个 移动终端中的具有通信质量需求的 R个移动终端, M≥l, 1≤R≤M, 也就 是说, 接入无线接入设备中的移动终端可以是部分或者全部具有通信质量 需求, 本发明的实施例只考虑具有通信质量需求的移动终端, 例如: 具有 通信质量需求的移动终端可以是运营商的一些 VIP, 运营商一般会考虑优 先满足具有通信质量需求的移动终端。 具体地, 可以包括以下多种场景, 第一种场景是 R>1, 在1 >1时包括两种情况, 一种是 M>R, 例如, 接入 无线接入设备的移动终端有 100个 (M=100 ) , 其中, 具有通信质量需求 的移动终端具有 80个 (R=80 ) , 另一种是 R=M, 例如, 接入无线接入设 备的移动终端有 100个 (M=100 ) , 并且, 其中的 100个移动终端都具有 通信质量需求 (R=100 ) 。 第二种场景是 R=l, 在 R=l时包括两种情况, 一种是 M=l, 即接入无线接入设备的移动终端是 1个 (R=l ) , 并且该移 动终端具有通信质量需求 (R=l ) , 另一种是M>1, 例如: 接入无线接入 设备的移动终端有 100个 (M=100 ) , 其中具有通信质量需求的移动终端 只有 1个(R=l ) 。 本发明的实施例只考虑具有通信质量需求的移动终端, 因此, 本发明的实施例在分别针对 R>1和 R=l进行描述时, 对接入无线 接入设备的总的移动终端的数量不作限制。
移动终端集合的通信质量需求为 R个移动终端中预定数量或者全部数量 的终端中的每个终端满足单个移动终端的通信质量需求, 例如, R=100, 预 定数量为大于 80,则当 100个移动终端中有 80以上的移动终端满足单个移动终 端的通信质量需求, 则认为第一组无线接入链路的质量满足移动终端集合的 通信质量需求; 其中, 单个移动终端的通信质量需求可以包括下述至少一种: RSSI强度不低于 RSSI阈值、 接入速率不低于接入速率阈值、 接入带宽不低于 接入带宽阈值、 或, 当前的业务类型与最低链路质量的要求等。 针对接入无 线接入设备的移动终端中只有一个具有通信质量需求的情况, 即 R=l的情况, 若第一组无线接入链路满足单个移动终端的通信质量需求, 则可以确定第一 组无线接入链路满足移动终端集合的通信质量需求。
针对接入无线接入设备的移动终端中具有多个通信质量需求的情况, 即
R〉i的情况,移动终端集合的通信质量需求为 R个移动终端中满足单个移动终 端的通信质量需求的个数与 R的比值大于预设值。 也可以理解为 R条第一无线 接入链路中满足单个移动终端的通信质量需求的第一无线接入链路的个数与 R的比值大于预设值, 例如, R=10, 则第一组无线接入链路中具有 10条第一 无线接入链路, 假设, 有 5条第一无线接入链路分别满足 5个单个移动终端的 通信质量需求, 再假设, 预设值为 80%, 则在这种情况下 10条第一无线接入 链路中满足单个移动终端的通信质量需求的第一无线接入链路的个数 (5)与 R ( 10 ) 的比值是 50%, 小于预设值, 则确定第一组无线接入链路的质量不满 足移动终端集合的通信质量需求。 若 10条第一无线接入链路中满足单个移动 终端的通信质量需求的第一无线接入链路的个数与 R的比值大于 80%,则确定 第一组无线接入链路满足移动终端集合的通信质量需求。 需要说明的是, 判 断第一无线接入链路是否满足单个移动终端的通信质量需求过程, 与针对 R=l的情况下, 判断第一组无线接入链路的质量是否满足移动终端集合的通 信质量需求相同, 也就是, 单个移动终端的通信质量需求与 R=l的情况下的 移动终端集合的通信质量需求相同。
无线接入设备可以周期性的广播自己的存在, 从而保证有移动终端发现 该无线接入设备后通过无线方式接入到本无线接入设备。
无线接入设备可以通过定时检测获知第一组无线接入链路的质量; 具体 地, 可以通过定时获取表征第一组无线接入链路的质量的参数来完成, 其中, 针对 R=l的情况, 第一组无线接入链路与第一无线接入链路相同, 可以用来 表征第一组无线接入链路的质量的参数可以是: 移动终端到无线接入设备之 间的 RSSI信息、 移动终端用户的接入速率、 带宽信息或者移动终端的业务类 型等; 针对 R>1的情况, 第一组无线接入链路包括 R条第一无线接入链路, 用 来表征第一组无线接入链路的质量的参数可以是一个比值,该比值为 R条第一 无线接入链路中满足移动终端的通信质量的第一无线接入链路的个数与 R的 比值。
也可以通过移动终端定时上报参数的方式获知无线接入设备与 R个移动 终端之间的 R条第一无线接入链路的质量, 当 R=l时, 第一无线接入链路的质 量也就是第一组无线接入链路的质量, 当1 >1时, 无线接入设备根据 R条第一 无线接入链路的质量确定第一组无线接入链路的质量,也就是确定 R条第一无 线接入链路中满足移动终端的通信质量的第一无线接入链路的个数与 R的比 值为第一组无线接入链路的质量。
以 R=l, 移动终端的通信质量需求为 RSSI强度不低于 RSSI阈值为例进行 说明, 当无线接入设备检测到的第一组无线接入链路的 RSSI低于 RSSI阈值 时,则确定第一组无线接入链路的质量不满足移动终端集合的通信质量需求。 当移动终端集合的通信质量需求为多个时, 若无线接入设备检测到第一 组无线接入链路的质量不满足其中任何一个要求, 则确定第一组无线接入链 路的质量不满足移动终端集合的通信质量需求。
需要说明的是, 定时检测只是一种实现方式, 本发明还可以根据实际需 要, 采用其他的方式检测, 本发明对此不作限制。
S802 : 当无线接入设备判断第一组无线接入链路的质量不满足移动终 端集合的通信质量需求时, 上述无线接入设备从当前位置移动到目标位 置。
其中, 无线接入设备移动到目标位置时, 第二组无线接入链路的质量 满足上述移动终端集合的通信质量需求, 其中, 第二组无线接入链路包括 R条第二无线接入链路, 第二无线接入链路为无线接入设备在目标位置到 R个移动终端的任一移动终端之间的无线接入链路。
第一种实现方式是, 当第一组无线接入链路的质量不满足移动终端集 合的通信质量需求时, 就触发无线接入设备就从当前位置移动到目标位 置。
第二种实现方式是, 当第一组无线接入链路的质量不满足移动终端集 合的通信质量需求时, 学习历史时间段内第一组无线接入链路的质量, 根 据历史时间段内第一组无线接入链路的质量及当前的检测结果确定是否 触发无线接入设备移动。 也就是, 在无线接入设备从当前位置移动到目标 位置之前, 还包括: 无线接入设备判断最近的前 N次检测第一组无线接入 链路的质量是否满足移动终端集合的通信质量需求, 其中 N为大于等于 1 的整数,只有在前 N次检测第一组无线接入链路的质量不满足移动终端集 合的通信质量需求时, 无线接入设备才从当前位置移动到目标位置, 这样 可以避免无线接入设备的不必要的移动。
针对第二种实现方式, 举例来说明, 假设, 在前 N次检测第一组无线 接入链路的质量一直都满足移动终端集合的通信质量需求, 第一次检测到 第一组无线接入链路的质量不满足因素和条件, 可能是因为无线接入设备 与移动终端直接有障碍物通过、 或者是有干扰源通过导致了第一组无线接 入链路质量的下降, 当障碍物通过之后, 或者干扰源消除之后, 第一组无 线接入链路的质量则会恢复, 也就是, 在这种情况下, 第一组无线接入链 路的质量只是在短时间内下降, 无需无线接入设备进行移动, 这样, 可以 避免无线接入设备不必要的移动。假设, 在前 N次检测到第一组无线接入 链路的质量都不满足移动终端集合的通信质量需求, 并且, 当前检测到的 第一组无线接入链路的质量依然不满足移动终端集合的通信质量需求, 在 这种情况下才通过无线接入设备从当前位置移动到目标位置的方式来满 足移动终端集合的通信质量需求。
当无线接入设备确定要通过无线接入设备移动的方式满足移动终端集合 的通信质量需求之后, 首先要获取获取目标位置, 其中一种实现方式是无线 接入设备根据 R条第一无线接入链路的参数确定目标位置,。 然后, 规划无线 接入设备从当前位置移动到目标位置的路径。
首先, 下面详细介绍获取目标位置的过程:
第一歩: 无线接入设备根据 R条第一无线接入链路的参数获取 R个移动终 端分别相对于无线接入设备的位置信息。
其中, 第一无线接入链路的参数包括第一无线接入链路上传输的信号的 参数以及与第一无线接入链路相关的天线的参数, 其中, 第一无线接入链路 上传输的信号的参数包括: 无线信号的强度、 方向、 时延、 TOA、 AOA等, 与第一无线接入链路相关的天线的参数包括: 通过第一无线接入链路传输信 号的移动终端接入无线设备的天线的波束的方向。当存在多条无线链路时候, 参数还进一歩包括, 根据上述无线信号的强度、 方向、 时延等特性得到的关 于 RSSI, 无线电波方向及通信两端的距离等相关参数的特点所做的分布情况 统计, 可用于做位置估计等。
位置信息是指移动终端相对于无线接入设备的方向和 /或距离, 即可以根 据移动终端相对于无线接入设备的方向和 /或距离确定移动终端相对于无线 接入设备的位置信息, 当然, 位置信息也可以是移动终端的坐标信息。
本发明确定 R个移动终端中每个移动终端相对于无线接入设备的位置信 息的方法相同, 在此, 仅以确定一个移动终端相对于无线接入设备的位置信 息的方法为例进行详细说明, 确定其他的移动终端相对于无线接入设备的位 置信息的方法类似, 在此不再赘述。
本发明包括但不限于下述两种确定移动终端相对于无线接入设备的位置 的方式: 第一种实现方式, 常常应用于无线接入设备具有智能天线的场景, 以智 能天线中的定向天线为例进行说明, 定向天线是指在某一个或某几个特定方 向上发射及接收电磁波特别强, 而在其它的方向上发射及接收电磁波则为零 或极小的一种天线。 当采用定向天线来发射信号后, 就可以把信号的发射区 域从一个圆形缩小到一个扇形, 这样就可以根据天线波束方向确定移动终端 相对于无线接入设备的方向, 提高定位精度。 具有定向天线的无线接入设备, 可以将基于信号强度的方法与无线信号的定向特征结合起来, 再根据无线接 入设备和天线波束方向的映射, 得到移动终端相对于无线接入设备的方向。 如表 1所示, 表 1见图 3所示实施例中的表 1, 在此不再绘制。 以表 1为例, 若移 动终端通过无线接入设备的天线波束 1接入无线网络,则可以确定移动终端在 相对于无线接入设备的正东方向; 若移动终端通过无线接入设备天线波束 2 接入无线网络, 则可以确定移动终端在相对于无线接入设备的正东偏南 30°方 向, 即移动终端相对于无线接入设备的方向可以通过其接入无线网络的无线 接入设备的天线波束确定。 可以理解的是, 无线接入设备中会存储移动终端 当前是通过哪个波束接入无线网络的。 为了便于理解, 本发明还给出了定向 天线波束或覆盖扇区定位移动终端的示意图, 如图 4所示, 图 4为本发明定向 天线波束定位移动终端的示意图, 其中, 每个天线波束对应一个方向。 天线 波束越多, 每个天线波束对应的扇区越小, 定位的方向越精确。
无线接入设备通过定向天线接收信号, 无线接入设备通过无线接入设备 接收这些信号来估算到移动终端相对于无线接入设备的距离, 从而获取移动 终端的位置信息, 例如: 无线接入设备可以根据到达时间 TOA确定移动终端 相对无线接入设备的距离。
采用第一种实现方式获取移动终端相对于无线接入设备的位置信息, 易 于实施、 节省开销、 且可用于室内大范围的高精度的定位。
第二种实现方式以应用于无线接入设备具有多天线阵列场景为例, 但不 限于这种场景,无线接入设备根据 R个移动终端分别到天线阵列中的两个天线 的到达角确定 R个移动终端分别相对无线接入设备的方向与距离。
同样的, 下面以确定一个移动终端相对无线接入设备的方向与距离为例 进行说明, 确定其他移动终端相对无线接入设备的方向与距离的方法类似, 在此不再赘述。 具体地, 根据移动终端分别到天线阵列中的两个天线的到达角确定移动 终端相对无线接入设备的方向与距离, 由于无线通信中移动终端和无线接入 设备周围的散射环境不同, 使得多天线系统中不同位置的天线经历的衰落不 同, 从而产生角度色散, 即空间选择性衰落。 因此, 随着智能天线和多输入 MIMO系统的引入, 信道信息从原来的二维信息 (时间、 频率), 扩充到三维 信息 (时间、 频率、 空间), 因此, 与单天线的研究不同, 在对多天线的研究 中, 室内定位可以充分利用诸如 AOA、 AOD之类的空间角度的信息。 针对 WLAN系统, 无线接入设备多天线阵列配置已经越来与越普遍, 因此可以通 过多天线的 AOA、 TOA和 TDOA参数进行移动终端的定位。 基于 TDOA技术 的定位算法, 在高斯噪声环境下能取得较好的定位精度。 随着智能天线阵在 基站中的使用, 当无线接入设备与移动终端之间为视距 (LOS)环境时, 基站能 够测得比较精确的 AOA值, 利用 TDOA与 AOA的混合定位方法, 定位精度比 只用 TDOA定位方法进一歩提高。
以利用两个天线的 AOA进行定位为例进行描述,图 5为本发明利用两个天 线的 AOA进行定位的示意图, 如图 5所示, 天线 1、天线 2和移动终端三个点分 别为三角行的三个顶点, 坐标分别为 (χι, y , ( χ 2, ^ ), (χ™, ^ ), 天线
1和移动终端之间的边长为 i, 天线 2和移动终端之间的边长为 ^, 其中, 和 ^可以通过根据 TOA确定移动终端相对无线接入设备的距离。 移动终端的坐 标 (χ™, 则可以根据图 3所示实施例中的公式 (1 ) 和公式 (2) 获得: 针对第二种实现方式, 当无线接入设备检测到多个 ΑΟΑ时, 具体采用哪 两个 ΑΟΑ进行计算, 可以进一歩通过传感器获取环境信息, 以确定哪个 ΑΟΑ 是直接从移动终端过来的, 哪个 ΑΟΑ是通过障碍物反射过来的, 通过障碍物 反射的情况如图 6所示, 图 6为本发明中通过障碍物反射的 ΑΟΑ的示意图, 通 过删除通过障碍物反射过来的干扰 ΑΟΑ方向, 准确估计用户位置。
类似的, 还可以用 ΤΟΑ和 TDOA, 以及上述多种无线信号统计特性联合 来做移动终端的定位。 基本做法就是基于 TOA、 DOA、 接收信号强度 (RSS) 等参数求解几何方程的定位方法或是几种参数的联合定位移动终端的位置。 详细的求解过程, 此处不再赘述。
第二歩:无线接入设备根据 R个移动终端相对无线接入设备的位置信息确 定目标位置。 可选地,在根据 R个移动终端相对无线接入设备的位置信息确定目标位置 时,还可以结合无线接入设备和 R个移动终端所处的环境,确定出更为准确可 行的目标位置。也可以在根据 R个移动终端相对无线接入设备的位置信息确定 目标位置之后,再根据无线接入设备和 R个移动终端所处的环境,调整上述目 标位置, 得到调整后的目标位置。
具体地, 当确定了 R个移动终端相对无线接入设备的位置信息之后,如果 无线接入设备本地具有无线接入设备和 R个移动终端所处环境的全局详细地 图(也可以外部输入), 则可以直接根据自身的位置、 感知到的障碍物和地图 上标识的障碍物信息、 根据最短距离等路径规划原则, 确定需要移动的目标 位置, 目标位置具体可以通过方向、 坐标、 时间及速度等信息标识。
如果无线接入设备本地不具有无线接入设备与 R个移动终端所处环境的 全局详细地图, 则可以先获取无线接入设备与 R个移动终端所处的环境。 可 通过无线接入设备采用传感器感知无线接入设备与 R个移动终端所处的环境 中的障碍物信息, 根据传感器感知的障碍物信息构造无线接入设备与 R个移 动终端所处的环境。 具体地, 无线接入设备根据传感器感知障碍物的信息, 在平面图上抽取出障碍物的质心作为顶点, 基于沃罗诺伊图(Voronoi)理论, 采用近似构造法,构造一般环境的 Voron 图, 即相当于模拟了无线接入设备 与移动终端之间的环境。 如图 7所示, 图 7为本发明的无线接入设备的通过 传感器感知的构造的环境, 图中各圆圈即为本发明无线接入设备的传感器感 知的障碍物。
可选地, 如果无线接入设备的计算能力支持, 其可以在本地模拟无线接 入设备移动到目标位置之后, 第二组无线接入链路是否能够满足移动终端集 合的通信质量需求, 若模拟结果为是, 即无线接入设备移动到目标位置之后, 第二组无线接入链路可以满足移动终端集合的通信质量需求, 则无线接入设 备触发无线接入设备则执行移动到目标位置, 若否, 无线接入设备则重新规 划目标位置。
然后, 下面再介绍规划无线接入设备从当前位置移动到目标位置的路径 过程:
确定目标位置之后, 通过将无线接入设备当前位置和目标位置连入 Voronoi图, 形成无线接入设备运动的无碰撞路径网络。 把障碍物近似成质点 那么无线接入设备沿着环境障碍物的 Voronoi边行走碰到障碍物的几率是最小 的。 或者, 通过其他的方式规划当前位置到目标位置的路径信息, 路径信息 可以是一个目标位置的点的坐标、 或者一个角度标识的方向、 或者是当前位 置到目标位置之间的多个连续的点坐标,或者是某个方向上的连续移动时间、 以及移动的速度等。 简单来说, 路径规划可以只规划出无线接入设备移动的 下一个点的位置或方向, 而无线接入设备如何移动路径不做规划。 当无线接 入设备通过上述多种移动终端定位机制,定位出了移动终端的空间位置为 P r, Θ ), 即在以无线接入设备本地坐标的 Θ方向上,距离为 r的点。 上述坐标为二 维坐标, 在平面的机械装置, 如用轮子驱动的接入点装置中, 无需在进一歩 做坐标转换, 可以直接用该信息, 做下一歩处理。 当需要转换成三维空间中 的位置时, 可以无线接入设备的高度等信息, 转换成机械控制单元可识别的 坐标 P'(X',y',Z':>,转换后的目标位置会放入无线接入设备当前存储的本地的地 图中, 该地图包含了传感器模块感知的环境信息, 如障碍物信息等。
规划出来的路径信息 (即目标位置信息) 可以用如下形式表示:
1、 方向: T1 (α), 即沿着以无线接入设备的当前为诶之为坐标系远点的 α方向移动;
2、 方向 +距离方式: Tl ( a, L ), 即沿着以无线接入设备的当前位置为 坐标系原点的坐标系的 α方向, 平移 L距离。
3、 方向 +时间: Tl (a, t), 即沿着以无线接入设备的当前位置为坐标系 原点的坐标系的 α方向, 移动 t时间。
4、 方向 +速度 +时间方式: T2 (α, ν, t), 即无线接入设备沿着以无线接 入设备的当前位置为坐标系原点的坐标系的 α方向, 以速度 V平移 t时间后停 止; 这里, 因为有速度的规划信息, 因此, 除了获取移动终端的位置信息, 还需要更具位置的变化规律, 预测无线接入设备移动的速度;
5、 目标点位置方式: T3 ( X , y, z), 即无线接入设备移动到空间坐标为
( X , y, z ) 的点后停止移动。
6、 多点组成的连续路径: 可以是上述多种方式的组合, 也可以是某一种 方式, 区别是, 该连续路径, 包含了多歩移动的点的信息。
当规划出路径信息之后, 无线接入设备根据路径信息移动到目标位置之 后, 无线接入设备接收无线接入设备反馈的第二组无线接入链路的质量与移 动前的第一组无线接入链路的质量的比较结果, 无线接入设备根据比较结果 以及第二无线接入链路的参数, 确定下一次移动的目标位置。 gp, 无线接入 无线接入设备移动到目标位置之后会对比移动后的无线接入链路是否满足移 动终端集合的通信质量需求, 若满足, 则反馈规划成功的反馈信息, 若不满 足, 则反馈规划失败的反馈信息, 以供无线接入设备进一歩规划路径。
本发明实施例, 通过无线接入设备检测第一组无线接入链路的质量是否 满足移动终端集合的通信质量需求, 若无线接入设备判断第一组无线接入链 路的质量不满足移动终端集合的通信质量需求, 无线接入设备从当前位置移 动到目标位置, 以使移动后的第二组无线接入链路满足移动终端集合的通信 质量需求, 即通过无线接入设备的移动提高无线接入链路的质量, 以满足移 动终端集合的通信质量需求。
图 9为本发明的无线接入服务方法实施例三的流程示意图,本实施例是针 对图 1所示的场景,即接入无线接入设备的移动终端中只有一个移动终端具有 通信质量需求的情况, 也就是 R=l的情况, 如图 9所示, 本实施例的方法包括: S901 : 无线接入设备检测第一组无线接入链路的质量是否满足单个移动 终端的通信质量需求。
本歩骤与图 8所示实施例的歩骤 S801类似, 在此不再赘述。
S902: 当无线接入设备判断第一组无线接入链路的质量不满足单个移动 终端的通信质量需求时, 无线接入设备通过向不同的方向移动第一距离, 确 定接收信号最强的方向为移动终端相对无线接入设备的方向。
如图 10所示, 图 10为本发明将无线接入设备所在的二维平面分成固定的 区域的示意图, 无线接入设备将其所在的二维平面分成 8个固定的区域, 即分 为 8个方向, 无线接入设备通过向不同的方向移动第一距离 (一般很短), 比 较各个方向的接入信号强度, 确定接入信号最强的方向为移动终端相对无线 接入设备的方向。
S903 : 无线接入设备根据 TOA确定移动终端相对无线接入设备的距离。 即根据信号的传播速率与时间获得信号传输的路径的长短, 即无线接入 设备与移动终端之间的距离。
S904: 无线接入设备结合移动终端相对无线接入设备的方向和距离, 确 定目标位置。 可参见图 8所示实施例的具体描述, 在此不再赘述。
无线接入设备从当前位置移动到目标位置。
根据机械运动原理进行移动, 对此, 本发明不作详细描述。
可选地, 当无线接入设备移动到目标位置之后, 还可以反馈路径规划的 效果 (无线接入设备在目标位置与移动终端之间的第二组无线接入链路质 量)。 以使无线接入设备根据反馈效果确定下一次移动的目标位置。
本实施例是针对无线接入设备只有一个具有通信质量需求的场景, 通 过无线接入设备尝试向不同的方向移动, 根据接收信号的强度确定移动终 端相对无线接入设备的方法, 再根据 TOA等方式确定移动终端相对无线 接入设备的距离, 进而结合移动终端相对无线接入设备的方向和距离确定 目标位置。

本歩骤的详细描述可以参见 S801 , 不同的是, S801的执行主体是无线接 入设备, 本歩骤是远端控制中心, 但其实现的功能相同, 在此不再赘述。
S1102:当上述远端控制中心判断上述第一组无线接入链路的质量不满足 移动终端集合的通信质量需求, 上述远端控制中心触发上述无线接入设备从 当前位置移动到目标位置。
其中, 上述无线接入设备移动到上述目标位置时, 第二组无线接入链路 的质量满足上述移动终端集合的通信质量需求, 其中, 上述第二组无线接入 链路包括 R条第二无线接入链路, 上述第二无线接入链路为无线接入设备在 目标位置到上述 R个移动终端中的任一移动终端之间的无线接入链路。
