Description

定位信息的发送方法与装置 技术领域
本发明涉及终端的用户终端（ UE, User Equipment )的定位技术， 尤其 涉及一种定位信息的发送方法与装置。 背景技术
在目前定位的协议中， 支持基于演进的小区标识（ E-CID, Evolved Cell Identifier ) 的 UE定位方法。 该方法通过 UE或基站测量下行或上行无线信 号， 结合 UE所在小区的标识来估算 UE的位置信息。 同时， 基于 E-CID的 定位方法还支持基于 UE和基于基站的方式， 其中基于 UE的方式是指由 UE自己根据测量结果和基站的标识等信息计算位置信息， 然后将位置信息 反馈给网络中的服务移动定位中心 （ SMLC , Serving Mobile Location Center ); 基于基站的方式是指由基站根据测量结果和基站的标识等信息计 算 UE的位置信息， 并将位置信息反馈给 SMLC。
在现有技术中， 指出由基站发送给 SMLC的信息中包括 UE的定时提 前信息， UE上行信号到达基站的角度， 对 UE上行信号的测量结果。 然而 如果釆用基于基站的方式， 现有协议并不支持将 UE 的位置信息上报给 SMLC , 这相当于不支持基站对 UE实现定位。 发明内容
有鉴于此， 本发明的主要目的在于提供一种定位信息的发送方法与装 置， 以通过基站也能实现对 UE的准确定位， 并将位置信息上"¾至网络侧。
为达到上述目的， 本发明的技术方案是这样实现的：

优选地， 所述用户终端的位置信息或所述基站的位置信息承载于新设 的专用信息中。
优选地， 所述用户终端的位置信息承载于新设的专用信息中时， 所述 基站不再向所述 SMLC发送定位信息或所发送的定位信息为空。
一种定位信息的发送装置， 包括：
定位单元， 用于对用户终端进行定位；
发送单元， 用于将所述定位单元确定的所述用户终端的位置信息或所 述基站的位置信息发送给服务移动定位中心 SMLC。
优选地， 所述定位单元包括：
测量模块， 用于对所述用户终端上行无线信号进行测量， 测量项包括 载波的信号强度指示、 参考信号的接收功率及参考信号接收质量中的至少 一种；
位置确定模块， 用于根据所述测量模块的测量结果和所述用户终端当 前所属基站的地理位置信息确定所述用户终端的位置信息。
优选地， 所述发送单元将所述用户终端的位置信息或所述基站的位置 信息承载于所述用户终端所属基站与所述 SMLC之间的定位信息中。
优选地， 所述用户终端的位置信息承载于所述定位信息中时， 所述定 位信息中的所述用户终端的定时提前信息， 所述用户终端上行信号的到达 角度以及测量结果所在的网元为空。
优选地， 所述发送单元将所述用户终端的位置信息或所述基站的位置 信息承载于新设的专用信息中。
优选地， 所述用户终端的位置信息承载于新设的专用信息中时， 所述 发送单元不再向所述 SMLC发送定位信息或所发送的定位信息为空。
本发明中， 通过扩展基站与 SMLC之间的定位信息， 增加携带 UE的 位置信息或基站位置信息的网元，使基站也能将 UE的位置信息或基站位置 信息上报至 SMLC, 从而实现基站对 UE的定位。 本发明是对现有对 UE定 位方式的弥补， 实现简单且实用。 附图说明
图 1是本发明定位信息的发送方法的流程图；
图 2是本发明定位信息的发送装置的组成结构示意图；
图 3是本发明定位单元的组成结构示意图。 具体实施方式
本发明的基本思想是： 通过扩展基站与 SMLC之间的定位信息， 增加 携带 UE的位置信息或基站位置信息的网元，使基站也能将 UE的位置信息 或基站位置信息上报至 SMLC,从而实现基站对 UE的定位。本发明是对现 有对 UE定位方式的弥补， 利用现有的定位信息发送 UE的位置信息， 实现 简单且实用。
为使本发明的目的、 技术方案和优点更加清楚明白， 以下举实施例并 参照附图， 对本发明进一步详细说明。
步骤 101 : SMLC决定使用上行 E-CID定位方法来对 UE进行定位， 并 且釆用基于基站的方式。
步骤 102: SMLC将定位请求发送给基站。 这里的基站是当前为 UE服 务的基站。
步骤 103:基站接收到 SMLC的定位请求后，对 UE的上行无线信号进 行测量。 测量项包括载波信号强度指示、 参考信号接收功率以及参考信号 接收质量中的至少一项。 上述各测量项由基站中的对应的测量单元完成。
步骤 104: 在获得终端的无线信号测量结果后，基站根据测量结果和自 己的地理位置信息计算 UE的位置信息。 具体的， 基站根据 UE的上行信号 到达角度（即 UE的波达角）、 UE当前服务小区的小区标识信息以及 UE上 行信号的信道质量指示或参考信号接收功率或参考信号接收质量确定 UE 距离基站的距离， 其原理是： 距离基站越远的 UE, 上行信号的信号强度就 越弱， 通过上下信号的信号强度的相关信息， 即可确定出 UE的位置信息。 UE服务小区的小区标识信息包括演进的小区全球标识 （ ECGI , Evolved Cell Global Identifier )或物理小区标识 ( Physical Cell ID )信息。
步骤 105: 基站发送 UE的位置信息给 SMLC。 具体的， 基站将 UE的 位置信息承载于基站与 SMLC之间的定位信息中， 而该定位信息之前并未 设置承载 UE 的位置信息的网元， 本发明对定位信息进行扩展， 增加承载 UE的位置信息的网元， 如表 1、 表 2中所示， 表中斜体部分 "UE位置信 息 ( UE location information )，， 及 "基站位置信息 ( eNode B location information )" 是在定位信息中新增的网元。 UE 位置信息包括纬度 ( Latitude ), 经度（ Longitude )及海拔（ Altitude )信息等， 由基站根据前 述的测量结果确定。 基站位置信息包括地理坐标 （ geographical coordinate ) 等信息， 基站的位置信息在设置基站时即确定了其位置信息， 通过基站的 配置信息即可获取。 定位信息中还包括 UE无线信号时间提前（TA, Timing Advance )信息以及到达角 （ AoA, Angle of Arrival ), 还包括对 UE无线信 号测量结果的信息 （ E-UTRA Measurement Result List ) , 包括 ECGI或物理 小区标识信息、 载波接收信号强度 ( RSSI , Received Signal Strength Indicator ). 接收参考信号功率 ( RSRP , Reference Signal Received Power ) 和接收参考信号质量 ( S Q , Reference Signal Received Quality )。

表 3的信息结构意味着，如果是釆用基于基站的 UE定位方式，基站只发送 UE的位置信息即可， 其他信息如上行信号的测量结果等信息可不再发送， 基站发送基站的位置信息而不发送 UE的位置信息时，需要将原定位信息中 的其他信息也发送给 SMLC , 这是因为， 仅通过基站的位置信息不能实现 对 UE位置信息的确定，需要其他信息一起才能确定出 UE准确的位置信息。
需要说明的是， UE的位置信息也可以通过专门设置的新信息格式来承 载， 即在基站与 SMLC之间新设置信息来传送 UE的位置信息， 而系统中 原来的定位信息仍正常发送。 这样， 如表 3 所示的信息结构， 当新设置的 专用信息中承载的是 UE的位置信息时，原定位信息中的各网元中的信息可 以为空， 即不在发送原来定位信息中的任何信息。 而如果新设的专用信息 中承载的是基站的位置信息时， 原定位信息必须发送并且其中的各网元信 息必须携带。 需要说明的是，本发明中的 UE的位置信息与基站的位置信息可同时发 送给 SMLC, 最终确定出 UE的位置信息。
本发明是对现有对 UE定位方式的弥补，利用现有的定位信息或者、新 设的专用信息发送 UE的位置信息， 实现简单且实用。
图 2是本发明定位信息的发送装置的组成结构示意图， 如图 2所示， 本发明定位信息的发送装置包括定位单元 20和发送单元 21 , 其中， 定位单 元 20用于对用户终端进行定位； 发送单元 21用于将定位单元 20确定的用 户终端的位置信息或基站的位置信息发送给 SMLC。 发送单元 21将所述用 户终端的位置信息或所述基站的位置信息承载于所述用户终端所属基站与 所述 SMLC之间的定位信息中， 所述用户终端的位置信息或所述用户终端 所属基站的位置信息作为所述定位信息的新设网元。 所述用户终端的位置 信息承载于所述定位信息中时， 所述定位信息中的所述用户终端的定时提 前信息， 所述用户终端上行信号的到达角度以及测量结果所在的网元为空。 发送单元 21将所述用户终端的位置信息或所述基站的位置信息承载于新设 的专用信息中。 所述用户终端的位置信息承载于新设的专用信息中时， 所 述发送单元不再向所述 SMLC发送定位信息或所发送的定位信息为空。
图 3是本发明定位单元的组成结构示意图， 如图 3所示， 本发明定位 单元 20包括： 测量模块 201和位置确定模块 202 , 其中， 测量模块 201用 于对所述用户终端上行无线信号进行测量， 测量项包括载波的信号强度指 示、 参考信号的接收功率及参考信号接收质量中的至少一种； 位置确定模 块 202用于根据测量模块 201 的测量结果和所述用户终端当前所属基站的 地理位置信息确定所述用户终端的位置信息。
本领域技术人员应当理解， 图 2所示的定位信息的发送装置是为实现 前述的定位信息的发送方法而设置的， 图 2及图 3所示的装置中各单元及 各模块的功能可通过运行于处理器上的程序而实现， 也可通过具体的逻辑 电路而实现。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。
