Description

获取定位数据的方法、 装置及系统 技术领域
本发明涉及无线通信技术领域, 尤其涉及一种获取定位数据的方法、 装 置及系统。 背景技术
位置服务(Location Service, 简称 LCS)是移动通信网络通过测量无线 信号来确定用户设备(User Equipment, 简称 UE )地理位置信息及其移动速 度的技术。 目前主流的位置服务包括增强型网元标识(Enhance-Cell ID, 简 称 E— CID), 到达时间观察时间差 ( Observed Time Difference of Arrival , 简称 0TD0A)和辅助 GPS (Assisted GPS, 简称 A-GPS)三种不同的定位方法, 每种定位方法需要不同的网络配置, 通过选择与网络配置相适应的定位方法 可获得 UE的位置信息。
0TD0A 是一种根据三个基站与移动终端信号传播的时间差值进行定位的 技术, 总体分为两部分:
1、 终端获得其到各基站的时间, 生成信号到达每一对(每两个基站) 的 时间差。具体的: UE对基站进行监听并通过定位参考信号( Position Reference Signal, 简称 PRS)测量出信号到达每两个基站的时间, 在根据两个时间得到 到达两个基站的时间差。
2、 终端根据生成的时间差进行定位。 具体的: 每两个基站得到一个时 间差, 同时每两个基站形成一个双曲线定位区。 三个基站共得到 2 个双曲线 定位区, 求解出他们的交点, 并施以附加条件(如基站自身地理位置信息等) 就可得到 UE的确切位置。
在实现上述第一部分获取定位数据的过程中, 发明人发现现有技术中至 少存在如下问题: 在进行 0TD0A定位方法时, 需要依靠 UE自带的 LCS功能。 当 UE具有 LCS功能时, 先与基站进行空口控制信令交互, 造成终端和基站空 口信令负载的增加; 在通过空口控制信令与基站进行交互后, 再进行 PRS信 号的测量, 增加终端耗电, 降低终端使用时长。 若 UE不具有 LCS功能, 则无 法测量 PRS信号, 进而无法得到信号到达每一对基站的时间差, 因此无法进 行 0TD0A定位。 发明内容
本发明的实施例提供一种获取定位数据的方法、 装置及系统, 能够解决 使用 0TD0A进行定位时, 当 UE具有 LCS功能时, 先与基站进行空口控制信令 交互, 造成终端和基站空口信令负载的增加; 在通过空口控制信令与基站进 行交互后, 再进行 PRS信号的测量, 增加终端耗电, 降低终端使用时长。 若 UE不具有 LCS功能, 则无法测量 PRS信号, 进而无法得到信号到达每一对基 站的时间差, 因此无法进行 0TD0A定位的问题。

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, 所描述的实施例仅仅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。
本发明实施例提供了一种获取定位数据的装置, 所述装置位于接入基站 中, 如图 1所示, 所述接入基站包括,接口电路 1 1和处理器 12 , 图 1中还示 出了存储 1 3器和总线 14 , 该处理器 12、 接口电路 11和存储器 1 3通过总线 14连接并完成相互间的通信。 所述装置包括:
接口电路 11 , 用于向至少一个相邻基站发送配置信息, 所述配置信息用 于描述用户设备 UE进行接入操作所使用的预设物理信道, 所述接入基站为当 前为所述 UE提供服务的基站, 所述相邻基站为与所述接入基站覆盖范围相邻 或部分重叠的基站;
向所述 UE发送重连接指令, 所述重连接指令用于所述 UE向所述接入基 站发起接入流程;
接收所述 UE根据所述重连接指令发送的序列 Preamble信息的第一时刻。 接口电路 11在发配置信息时, 向周边全部相邻基站进行发送。 接入基站 具有固定的信号覆盖范围, 该信号覆盖范围存在下述两种情况:
1、 如图 2所示, 该信号覆盖范围中存在部分与其他信号覆盖范围部分重 叠的情况, 提供重叠覆盖区域的基站为相邻基站。 图 2 所示的是两个相邻基 站同时与接入基站具有重叠覆盖区域的情况。
1、如图 3所示,该信号覆盖范围的边缘与其他信号覆盖范围的边缘相接, 提供上述其他信号的基站为相邻基站。 图 1 所示的是两个相邻基站同时与接 入基站的边缘相接的情况。
该接口电路 11用于实现接入基站与相邻基站、 接入基站与 UE进行通信 的数据传输接口, 例 ¾口通用公共无线接口 (Common Publ ic Radio Interface, 简称 CPRI ), 用于与基站的射频部分连接, 通过天线接收 UE发送的 Preamble 信息。
处理器 12 , 用于记录所述接口电路 11接收到所述 UE根据所述重连接指 令发送的序列 Preamble信息的第一时刻。
处理器 12通过总线 14将记录的第一时刻存储到存储器 13中。
所述接口电路 11还用于, 接收所述相邻基站发送的第二时刻, 所述第二 时刻为所述相邻基站接收到所述 UE根据所述重连接指令发送的 Preamble信 息的时刻。
接口电路 11通过总线 14将记录的第一时刻存储到存储器 13中。 所述处理器 12还用于, 根据存储器 13存储的所述第一时刻和所述第二 时刻确定传输时差, 所述传输时差用于对所述 UE进行定位。
需要说明的是, 本发明实施例所述的处理器 12可以是一个处理器, 也可 以是多个处理元件的统称。 例如, 该处理器 12 可以是中央处理器 (Central Processing Unit,简称 CPU),也可以是特定集成电路( Appl icat ion Specific Integrated Circuit, 简称 ASIC), 或者是被配置成实施本发明实施例的一个 或多个集成电路, 例如: 一个或多个 !¾:处理器 ( digital signal processor, 简称 DSP), 或, 一个或者多个现场可编程门阵列 (Field Programmable Gate Array, 简称 FPGA)。
存储器 13可以是一个存储装置, 也可以是多个存储元件的统称, 且用于 存储可执行程序代码等。 且存储器 13可以包括随机存储器(RAM), 也可以包 括非易失性存储器(non- volatile memory ), 例如磁盘存储器, 闪存(Flash) 等。
总线 14可以是工业标准体系结构 ( Industry Standard Architecture, ISA) 总线、 外部设备互连(Peripheral Component, PCI ) 总线或扩展工业 标准体系结构 ( Extended Industry Standard Architecture, EISA ) 总线等。 该总线 14可以分为地址总线、 数据总线、 控制总线等。 为便于表示, 图 1中 仅用一条粗线表示, 但并不表示仅有一根总线或一种类型的总线。
优选的 ,所述接入基站和所述相邻基站均为演进型基站( evolved Node B, 简称 eNB)。 本发明实施例提供的一种获取定位数据的装置, 能够由接口电路 11向至 少一个相邻基站发送配置信息、 向所述 UE发送重连接指令, 接收所述 UE根 据所述重连接指令发送的序列 Preamble信息, 处理器 12能够记录接口电路 11接收到所述 UE根据所述重连接指令发送的序列 Preamble信息的第一时刻 以接口电路 11接收所述相邻基站发送的第二时刻, 最后处理器 12根据所述 第一时刻和所述第二时刻确定传输时差。 现有技术由 UE通过测量 PRS信号确 定传输时差。 本发明通过接入基站通过向至少一个相邻基站发送配置信息, 使得相邻基站在配合信息描述的预设物理信道中监听 UE发送的信号, 接入基 站再向 UE发送重连接指令以使 UE在预设物理信道中发送 Preamble信息, 接 入基站和相邻基站分别记录监听到 Preamble信息的时刻, 相邻基站将将听到
Preamble信息的第二时刻发送到接入基站, 接入基站根据该第二时刻以及自 身监听到的第一时刻得到传输时差。 本发明中 UE仅需要执行一次连接流程, 即可完成定位, 无需依靠 UE 自身的 LCS功能。 当 UE不具备 LCS功能时, 接 入基站能够为 UE提供定位服务。 当 UE具备 LCS功能时, 接入基站代替 UE获 取传输时差, UE无需使用宝贵电量进行传输时差的获取, 进而提高终端的使 用时长。 此外, 接入基站从相邻基站处获得第二时刻, 接入基站和相邻基站 无需为 UE分配用于发送定位参考信号的空口资源,提高空口资源的使用效率。 同时, 由于使用 UE进行时间差测量需要执行测量配置、 UE测量和测量上报等 操作, UE进行上述操作时需要一定的数据传输时间, 本发明中无需指向上述 操作, 进而提高传输时差的获取速度。 此外, 现有技术使用的是 UE与基站之 间的通信信道, 其传输速度受到 UE所处环境的影响 (基站与 UE之间有多个 遮挡物或建筑物时, 信号质量降低导致传输速率降低), 因此定位响应时间较 长, 本发明中, 采用基站与基站之间的通信信道进行数据传输, 进一步提高 传输时差的获取速度。
本发明实施例还提供了一种获取定位数据的装置, 作为对图 1 所示装置 的具体说明, 所述接口电路 11还用于, 与所述相邻基站进行时间同步。
为了保证获取到的传输时差是在较为统一的时间下进行确定的, 在接口 电路 11向至少一个相邻基站发送配置信息之前, 接口电路 11与所述相邻基 站进行时间同步, 以保证接入基站和相邻基站使用相同的时间。
通过下述两种方式进行时间同步:
1、通过 GPS进行时间同步。 eNB通过全球定位系统(G loba l Pos i t ioning Sys tem, 简称 GPS )进行时间的更新。 GPS系统为卫星提供的定位及更新系统, 现有 GPS的定位指标为 +/-35ns (s i gma) ,基站的接入检测精度可以达到 12Ts , 即 390Ns左右, 在网络设备间往返的总的精度在 880Ns 以内, 因此总的定位 精度大概 260米以内。
2、通过 1588V2时钟进行时间同步。 1588V2点到点一跳的指标为 +/-30ns , eNB选用 1588V2作为时间同步时钟源, 精度都可以保证在 l O ONs以内。 本发明实施例提供的获取定位数据的装置, 能够在传输配置信息之前, 使接入基站和相邻基站之间进行时间同步, 保证确定出的传输时差的准确性。
本发明实施例还提供了一种获取定位数据的装置, 作为对图 1 所示装置 的具体说明, 所述接口电路 11 , 还用于向至少一个相邻基站发送物理随机接 入信道 PRACH信息。

所述接口电路 11 ,还用于向所述用户设备 UE发送物理下行控制信道指令 PDCCH order。
PDCCH order能够使 UE启动与接入基站之间的接入操作, 接入基站通过 获取接入操作中 UE发射的信号到信号传输的时间。
本发明实施例提供的获取定位数据的装置, 能够使用现有的信令与相邻 基站和 UE发送数据, 进而避免使用额外频谱进行通信, 节约带宽。

本发明实施例还提供了一种获取定位数据的装置, 作为对图 1 所示装置 的进一步说明, 所述处理单元还用于, 记录向所述用户设备 UE发送所述重连 接指令时的第三时刻;
根据所述第三时刻和所述第一时刻确定连接时长。 所述接口电路还用于, 将所述传输时差和所述连接时长上报核心网。 本发明实施例提供的获取定位数据的装置, 能够根据第三时刻和第一时 刻确定连接时长, 通过将传输时差和连接时长上报到核心网, 能够得到 UE的 定位信息。 现有技术由于获取连接时长的步骤繁瑣, 终端定位时间长。 本发 明中通过第三时刻和第一时刻能够确定连接时长, 避免 UE因测量造成使用时 长降低, 并能够减少数据传输的次数; 同时基站处理能力比 UE强, 进而提高 终端定位的速度。
本发明实施例还提供了一种获取定位数据的装置, 所述装置位于用户设 备 UE中, 如图 4所示, 所述装置包括:
接收器 21 , 用于接收接入基站发送的重连接指令, 所述重连接指令用于 所述 UE向所述接入基站发起接入流程。
UE根据重连接执行, 重新启动与接入基站的接入操作, 该接入操作为 UE 与接入基站建立连接的过程。
发射器 22 , 用于在预设物理信道中发射序列 Preamb l e信息。
该 Preamb le信息用于与接入基站进行接入操作。 由于发射器 22是在预 设物理信道中发射 Preamb le信息, 因此对该预设物理信道进行监听的相邻接 站也捕获到该 Preamb le信息。
本发明实施例提供的获取定位数据的装置, UE仅需要根据接入基站发送 的重连接指令发起接入流程, 即可达到 UE定位的效果。 现有技术中, UE需要 具有 LCS功能, 即 UE先向接入基站和相邻基站发起数据请求用以计算各基站 与 UE之间的传输时间, 再结合公式计算出 UE的位置, 步骤繁多且影响 UE耗 电量高缩短使用时长, 同时, UE在于各基站进行数据交互时, 通过 RRC信令 进行连接, 基站需要为该数据交互分配专门的空口资源, 占用基站空口资源。 本发明无需 UE具有 LCS功能, 同时在 UE定位过程中, 仅需要 UE根据重连接 指令执行一遍接入流程, 在解放 UE的同时, 提高的 UE定位的效率。 同时 UE 与接入基站之间无需进行 RRC信令交互, 进而节省信令开销。
本发明实施例还提供了一种获取定位数据的装置, 作为对图 4 所示装置 的具体说明, 所述接收器 21还用于, 接收接入基站发送的物理下行控制信道 指令 PDCCH order。
本发明实施例提供的获取定位数据的装置, 能够使用现有的信令与接入 基站进行通信, 进而避免使用额外频谱进行通信, 节约带宽。

现有技术由 UE通过测量 PRS信号确定传输时差。 本发明通过接入基站通 过向至少一个相邻基站发送配置信息, 使得相邻基站在配合信息描述的预设 物理信道中监听 UE发送的信号, 接入基站再向 UE发送重连接指令以使 UE在 预设物理信道中发送 Preamb le 信息, 接入基站和相邻基站分别记录监听到 Preamb le信息的时刻 ,相邻基站将将听到 Preamb le信息的第二时刻发送到接 入基站, 接入基站根据该第二时刻以及自身监听到的第一时刻得到传输时差。 本发明中 UE仅需要执行一次连接流程, 即可完成定位, 无需依靠 UE 自身的 LCS功能。 当 UE不具备 LCS功能时, 接入基站能够为 UE提供定位服务。 当 UE具备 LCS功能时, 接入基站代替 UE获取传输时差, UE无需使用宝贵电量 进行传输时差的获取, 进而提高终端的使用时长。 此外, 接入基站从相邻基 站处获得第二时刻, 接入基站和相邻基站无需为 UE分配用于发送定位参考信 号的空口资源, 提高空口资源的使用效率。 同时, 由于使用 UE进行时间差测 量需要执行测量配置、 UE测量和测量上报等操作, UE进行上述操作时需要一 定的数据传输时间, 本发明中无需指向上述操作, 进而提高传输时差的获取 速度。 此外, 现有技术使用的是 UE与基站之间的通信信道, 其传输速度受到 UE所处环境的影响(基站与 UE之间有多个遮挡物或建筑物时, 信号质量降低 导致传输速率降低), 因此定位响应时间较长, 本发明中, 采用基站与基站之 间的通信信道进行数据传输, 进一步提高传输时差的获取速度。
本发明实施例还提供了一种获取定位数据的方法, 作为对图 13所示方法 的进一步说明, 如图 14所示, 在步骤 1301、 向至少一个相邻基站发送配置信 息之前, 所述方法还包括:
步骤 1300、 接入基站与相邻基站进行时间同步。
本发明实施例还提供了一种获取定位数据的方法, 作为对图 13所示方法 的具体说明, 如图 15所示, 步骤 1301、 向至少一个相邻基站发送配置信息, 包括:
步骤 1501、 向至少一个相邻基站发送物理随机接入信道 PRACH信息。 步骤 1302、 向用户设备 UE发送重连接指令包括:
步骤 1502、 向用户设备 UE发送物理下行控制信道指令 PDCCH order。 本发明实施例还提供了一种获取定位数据的方法, 作为对图 13所示方法 的具体说明, 如图 16所示, 步骤 1303、 记录接收到所述 UE根据所述重连接 指令发送的序列 Preamble信息的第一时刻, 包括:
步骤 1601、 在预设物理信道中监听 UE 根据重连接指令发送的序列 Preamble信息。
步骤 1602、 当监听到 Preamble信息时, 接收 Preamble信息。
步骤 1603、 记录接收 Preamble信息的第一时刻。 本发明实施例还提供了一种获取定位数据的方法, 作为对图 1 3所示方法 的具体说明, 如图 17所示, 在步骤 1 302、 向用户设备 UE发送重连接指令之 后, 所述方法还包括:
步骤 1701、 记录向用户设备 UE发送重连接指令时的第三时刻。
步骤 1 303、 在记录接收到 UE根据重连接指令发送的序列 Preamb l e信息 的第一时刻之后, 方法还包括:
步骤 1702、 根据第三时刻和第一时刻确定连接时长。
步骤 1703、 将传输时差和连接时长上报核心网。
本发明还提供了一种获取定位数据的方法,所述方法用于用户设备 UE中, 如图 18所示, 所述方法包括:
步骤 1801、接收接入基站发送的重连接指令, 重连接指令用于 UE向接入 基站发起接入流程。
步骤 1802、 在预设物理信道中发射序列 Preamb le信息。
本发明实施例提供的获取定位数据的方法, UE仅需要根据接入基站发送 的重连接指令发起接入流程, 即可达到 UE定位的效果。 现有技术中, UE需要 具有 LCS功能, 即 UE先向接入基站和相邻基站发起数据请求用以计算各基站 与 UE之间的传输时间, 再结合公式计算出 UE的位置, 步骤繁多且影响 UE耗 电量高缩短使用时长, 同时, UE在于各基站进行数据交互时, 通过 RRC信令 进行连接, 基站侧需要为该数据交互分配专门的空口资源, 占用基站空口资 源。 本发明无需 UE具有 LCS功能, 同时在 UE定位过程中, 仅需要 UE根据重 连接指令执行一遍接入流程, 在解放 UE的同时, 提高的 UE定位的效率。 同 时 UE与接入基站之间无需进行 RRC信令交互, 进而节省空口信令开销。
进一步的, 所述接收接入基站发送的重连接指令包括:
接收接入基站发送的物理下行控制信道指令 PDCCH order。
本发明还提供了一种获取定位数据的方法, 所述方法用于相邻基站中, 如图 19所示, 所述方法包括:
步骤 1901、 接收接入基站发送的配置信息。 所述配置信息用于描述用户设备 UE 进行接入操作所使用的预设物理信 道, 所述接入基站为当前为所述 UE提供服务的基站, 所述相邻基站为与所述 接入基站覆盖范围相邻或部分重叠的基站;
步骤 1902、在所述配置信息描述的所述预设物理信道中监听所述 UE发出 的序列 Preamb le信息。
