Description

一种定位及其控制方法及装置 本申请要求在 2012年 07月 19 日提交中国专利局、 申请号为 201210251658.0、 发明 名称为"一种定位及其控制方法及装置"的中国专利申请的优先权, 其全部内容通过引用结 合在本申请中。 技术领域
本发明涉及通信技术领域, 尤其涉及一种定位及其控制方法及装置。 背景技术
在未来的移动通信系统中, 希望通过引入网络自优化的机制, 减少网络规划和操作维 护的人工参与, 由网络根据统计量自动优化参数, 降低网络的建设和运营成本。 为了减少 网络的运维成本, 希望能够釆取网络配置用户设备(User Equipment, UE )上报或者网络 侧收集方法, 减少人工路测的工作。 另一方面, 也希望能够获得普通路测无法到达的区域 的无线测量信息。 基于上述原因, 最小化路测被引入。 最小化路测中, 除了提供一些测量 信息外, 还需要提供当时发生的时间及尽可能精确的地理位置信息。 在已有的标准中, 已 经支持了在无法获取精确的 UE的经纬度信息的情况下, 可以上报对邻小区信号强度和盾 量的测量(这种测量也叫做 RF finger print测量)上报。 另外, 目前 2G和 3G的网络相对 成熟,有的网络已经建立了 RF finger print的地图,但是长期演进 ( Long Term Evolvement, LTE ) ( 4G ) 网络仍然处于建网阶段, 相关的 RF finger print的地图还没有形成, 那么 UE 上报 RF finger print的结果后, 也无法根据已经建成的地图模型来获取地理位置信息, 而 只能粗略估计离哪些邻小区更近。
定位筒介:
一、独立的 (standalone )全球卫星导航 ( Global Navigation Satellite System, GNSS )。 如果 UE具有 GNSS功能, 如全球定位系统( Global Positioning System, GPS ), 可以 直接利用 GPS获得 UE当前的位置, 这种称为 standalone GNSS定位。
目前 standalone GNSS主要被上层应用所启用, 还没有支持为了接入层的需求而触发。 在 LTE 系统中引入的辅助全球导航卫星系统 (Assisted Global Navagation Satellite System , A-GNS S )的定位方法, 主要是为了解决 standalone GNS S搜索卫星时间过长的问 题, 而让网络提供一些辅助数据, 让 UE更快地搜索到卫星, 从而更早地进行定位。 通常, A-GNSS 方法的启用也是上层应用或者第三方定位客户端发起, 没有为了最小化路测 ( Minimization of Drive Tests, MDT )或者接入层( Access Stratum, AS ) 的其他目的而触 发。 二、 观测到达时间差 (Observed Time Difference of Arrival, OTDOA ) 的定位方法。 在通用移动通信系统( Universal Mobile Telecommunication System, UMTS )中, OTDOA 方法主要依据 "系统帧号 (System Frame Number, SFN ) 观察时间差 (observed time difference, OTD )类型 2 ( SFN-SFN OTD type 2 ),, 的测量结果, 可以参考各小区的第一路 径类型 ( First Path Type )、 "下行导频时隙 (DwPTS)上的接收信号强度( Receiving Signal Strength, RSS ) ( RSS on DwPTS )"和 "终端的移动速度( UE Related Speed )"的测量结果, 估计 UE所在位置。 这些测量结果结合实际路测以及网络规划的结果, 可以用来有效估计 UE 所在位置。 该方法的测量精度取决于可测量小区的数目、 测量周期、 测量精度以及位 置估计算法。 并且, 可以通过一些存在非直达路径的定位系统的处理和补偿方法, # ^据测 量上报的 "First Path Type" , 保留了根据不同信道情况选择不同的估计器, 获得更好的位 置估计结果。
比如, 在时分同步码分多址接入 ( Time Division Synchronized Code Division Multiple Access, TD-SCDMA )系统中, 它是通过检测两个基站信号到达的时间差来确定 UE位置, 测量量为 SFN-SFN观察时间差( SFN-SFN Observed Time Difference ), 该测量由 UE执行。 OTDOA方法又称为双曲线定位, UE位于以两个基站为焦点的双曲线上。 由于确定 UE位 置需要建立两个以上的双曲线方程, 两条双曲线的交点为 UE 的二维位置坐标, 因此, OTDOA方法要求同时有三个以上的基站参与定位参数的测量。
OTDOA的基本算法原理:
假设不定位 UE的高度, 假设 UE的坐标为 ( X, y ), 则最少需要 3个基站信号被接收, 第 i个基站发射机的位置坐标为 (Xi, yi), i= 1, 2, 3。 UE观测的时间差分别为 τι,2» τ2,3' τι,3。 则解方程组: l(x-x2f +(y-y2f - li - .f +iy-y.f = Tl2C
< l(x-x3)2 + (y-y3)2 - l(x-Xi)2 + ( - if
l(x-x3)2 + (y-y3)2 -^(x-x2)2 + ( - 2) = ¾c 其中, c表示光速。
那么, 根据上式可以得到 UE的坐标(x, y)。 如果 UE测量正确, 且没有多径千扰的 影响, 那么以上 3个方程中存在冗余的一个, 也就是 3个方程是 2个不相关方程。
当方程只有一个解时, 该解即为 UE的坐标解。
当方程有 2个解时使用与本小区基站距离较小的那个解作为最后解, 对另一解进行抛 弃。 当方程无解时, 此次定位测量无效。
该方法的定位精度大 4既在 10-200米。 在 LTE系统中, 该方法的原理是类似的。 只是测量的量为参考信号时间差(Reference Signal Time Difference , RSTD ),其含义是接收到的两个小区的参考信号的时间差。与 UMTS 系统中的 SFN-SFN OTD type2是类似的。 在定位中的使用方法也是类似的。
LTE系统与 UMTS系统的 OTDOA方法还存在一个重要的差异, 在 UMTS系统中, OTDOA的辅助数据是可以通过系统信息广播发下来的, 可以让空闲 (idle )状态下的 UE 也能进行自身的定位。 但是, LTE系统中, 辅助数据只能发给连接状态下的 UE, idle下的 UE无法釆用该方法进行定位。
三、 RF finger print方法。
UE上报所测的邻小区和服务小区的信号盾量, 比如 LTE系统中, 测量参考信号接收 功率 ( Reference signal received power, RSRP )和参考信号接收盾量 ( Reference Signal Received Quality, RSRQ ), 在 UMTS ( 3G )系统中, 测量接收信号码功率( Received Signal Code Power, RSCP )和接收信号强度指示 ( Received Signal Strength Indicator, RSSI )等。 网络根据已经建立的指紋(finger print, 这里指终端在某个地点测到的服务小区以及邻小 区的信号盾量)地图, 来确定 UE的大概位置。
现有技术中引入的 MDT测量分类有:
立即上报的(Immediate ) MDT: 连接态进行的 MDT测量与上报。 复用无线资源管理 ( Radio Resource Management, RRM ) 测量机制, 一旦满足上报条件, 立即对演进基站 ( Evolved NodeB , e B )或无线网络控制器( Radio Network Controller, RNC )进行上艮。
记录的 (Logged ) MDT: 空闲态进行的 MDT测量, 在后续连接态进行上 ·¾。 一旦满 足了配置的触发条件, 将获取测量结果并进行储存(log ), 在后续的合适时机上报给 eNB 或 RNC。
当前 UE是否支持 standalone GNSS定位能力, 作为 UE能力中的一项告知网络侧。 但 现有技术中, 考虑到 UE的耗电及复杂性, MDT相关的位置信息是尽力提供的, 即如果有 有效的详细地理位置信息, 则在记录结果时包括该地理位置信息; 否则, 记录当时其他邻 小区的测量信息 (RF finger print ), 网络侧通过这些信息估算当时的地理位置信息, 并没 有为了 MDT目的而特别进行相关的定位过程来获得位置信息。
上述 Immediate MDT和 Logged MDT, 均是 UE侧进行 MDT测量量收集, 并关联地 理位置信息一块上报给网络侧。 当前针对服务盾量 (Quality of Service, QoS )验证这一 MDT用例, 同意了统计调度的 IP包吞吐量( Scheduled IP throughput )测量量, 该测量量 由基站侧来执行, 地理位置可以由 UE侧上 4艮, 具体细节还未确定。
由于进行 MDT收集时, 记录当时测量所在的位置信息是很重要的, 因此未来技术中 有必要对地理位置信息进行增强。
但是, 现有技术中如何对 MDT中的详细地理位置信息进行增强, 现在还未有结论。 如果通过 standalone GNSS定位强制获得详细地理位置信息, 不会给网络侧带来复杂度, 且精度高, 但并不是所有 UE都具备 standalone GNSS定位能力, 且在室内场景, GNSS信 号衰减大, 也不能使用 standalone GNSS进行定位。 另外 LTE网络处于部署阶段, 可能没 有定位服务, 而且网络部署变化会比较大, 比如不断的调整小区配置参数, 或者增减小区 等, 没有可靠的 RF finger print地图, 那么 UE提供的位置信息的可信度就很难保证。 发明内容 本发明实施例提供了一种定位及其控制方法及装置, 以及一种地图建立方法及装置, 用以通过异系统获取 UE位置信息并提供给 LTE系统使用, 从而为执行 LTE MDT功能提 供了更多的获取 UE位置信息的方式。

本发明实施例考虑到 2G和 3G的网络日益成熟,通过 2G、 3G定位的位置信息可靠性 更高一些, 也有利于 LTE形成自己的地图, 因此, 本发明提供了一种通过异系统获取位置 信息提供给 LTE系统使用的方法。
本发明提供的技术方案主要包括: 双模 UE通过另一个无线接入类型 (Radio Access Type, RAT ) 的定位功能来辅助完成 LTE模式的 MDT功能。 即接收 2G、 3G网络广播的 定位辅助数据来进行定位, 或者, 通过对 2G、 3G以及 LTE系统的网络进行 finger print的 测量, 通过 LTE系统的 logged MDT (终端在空闲状态下执行 MDT测量并记录下来, 等到 进入到连接状态时再上报给网络,这种方式叫 logged MDT,即记录的 MDT )或者 IMM MDT (终端在连接状态下测到 MDT的测量之后立即上报 MDT测量结果的方式称为 immediate MDT,即立即上报的 MDT )上报给 eNB,再发给运行、管理和维护( Operations、 Administration and Maintenance, 0AM )建立 LTE系统 RF finger print地图。

在 OAM侧, 参见图 3 , 本发明提供的一种地图建立方法, 包括:
5301、 获取 UE上报的 2G或 3G系统的定位结果, 和 /或邻小区及服务小区的信号盾 量测量结果;

下面给出几个具体实施例的说明。
实施例一:
UE支持 LTE和 3G系统的两种模式, 并且支持双待机, 即两个模式的系统可以同时 工作。 网络部署 3G和 LTE系统网络并存, 3G网络是覆盖较好的成熟网络, LTE网络是新 建的网络。 UE在开机注册期间通过 UE能力上报了自身的能力, 包括支持的模式, 支持双 模同时工作, 同时也上报了定位的能力和 MDT的能力。 LTE系统的基站收到后, 可以选 择该 UE执行 MDT任务。 如果 UE在收到 MDT配置之后, 无法上报位置信息, 即 UE没 有可用的有效的位置信息。 基站可以指示 UE通过不同于 LTE系统的无线接入类型系统进 行定位, 以辅助完成 LTE 系统的 MDT 功能, 即指示 UE 釆用无线接入类型系统间 ( inter-RAT )定位的方式来获取位置信息, 该信息也可以连同 MDT的配置一起发给 UE, 由 UE自行启动 inter-RAT的定位(即通过不同于 LTE系统的无线接入类型系统进行定位, 以辅助完成 LTE系统的最小化路测 MDT功能)。 UE的 3G模块根据 3G网络的系统信息 中的定位辅助数据以及自己所支持的定位方法, 自行决定釆用哪种定位方法。 例如, UE 支持 GNSS的定位,则通过 3G的系统信息中所提供的 GNSS辅助数据进行 GNSS的定位, 或者, UE支持 OTDOA ( Observed Time Difference Of Arrival, 观测到达时间差)定位, 则 通过 3G的系统信息中所提供的 OTDOA辅助数据进行 OTDOA。然后,将定位结果提供给 LTE模块, 再通过 logged MDT或者 IMM MDT上报给 LTE网络。 对于 OTDOA的方法, 如果 UE根据辅助数据无法进行位置计算, 也可以将 OTDOA的测量结果发给 LTE模块, 通过 LTE模式上报给 LTE网络, 进行后台处理。
实施例二:
UE支持 LTE系统和 3G两种模式, 并且支持双待机, 即两个模式的系统可以同时工 作。 网络部署是 3G系统和 LTE系统网络并存, 3G网络是覆盖较好的成熟网络, LTE网络 是新建的网络。 UE在开机注册期间通过 UE能力上报了自身的能力, 包括支持的模式、 支 持双模同时工作, 同时也上报了定位的能力和 MDT的能力。 LTE的基站收到后, 可以选 择该 UE执行 MDT任务。 如果 UE在收到 MDT配置之后, 无法上报位置信息, 即 UE没 有可用的有效的位置信息。 基站可以指示其上报多系统的 RF finger print测量, 也可以 UE 自行开启多系统的 RF finger print测量。 UE的 3G模块执行 3G小区的 RSCP、和 /或 ISCP、 和 /或 RSSI等测量, 并将这些测量结果提供给 LTE模块。 在同一测量周期内, LTE模块也 执行对 LTE小区的 RSRP、 和 /或 RSRQ等 finger print测量。 如果 UE处于 LTE 空闲状态, 则在 MDT记录文件中将 3G和 LTE系统的相关测量结果记录下来, 并提供时间信息。 如 果 UE处于 LTE连接状态,则在测量上报中将 3G和 LTE的相关测量结果一起上报给 e B。 e B收到后将这些测量转发给 OAM。
OAM可以根据 3G的测量结果以及已经成熟的 3G RF finger print地图来获取 UE的大 概位置, 同时关联 LTE的 RF finger print的测量结果来建立 LTE的 RF finger print地图。 当然, 为了增加地图的准确性和可信度, 在建立地图的过程中, 应该釆集大量的样本, 而 不能基于一两个 UE的测量结果。
该实施例中的 UE是双模双待机。 但实际上, 也不排除双模单待机使用该方法。 如果 UE是双模单待机 UE, 即 UE支持两种模式,但一个时刻只能在一个模式下工作。只是 UE 在执行 LTE和 3G系统的测量的时候, 不能同时进行, 需要分时执行。 即 LTE模式下要留 出一段时间进行 inter-RAT的定位测量或者 RF finger print的测量, 在进行 LTE MDT上报 时, 将 inter-RAT的相关测量结果同时上 4艮给网络。
实施例三:
基于实施例一, 下面给出连接状态下, UE釆用 3G的 GNSS或者 OTDOA辅助定位的 主要流程如图 4所示, 其中 TCE是跟踪(trace )数据收集实体。 在图 4所示流程中, UE在 LTE下执行 MDT测量时, 如果无法获取地理位置信息, 网络才重新决定让 UE执行 inter-RAT定位。 实际上, 也允许网络在第一次配置 MDT测量 时就配置 UE执行 inter-RAT定位;也允许 UE在 LTE下无法获取位置信息的时候自动启动 inter-RAT定位。 相关 inter-RAT定位结果连同 MDT测量结果(如果有的话)通过 LTE模 块发送给网络。
补充说明: 在图 4所示流程中, UE执行定位测量的同时, 如果需要的话, 也会执行 MDT的相关测量。
实施例四:
基于实施例一, 下面给出空闲状态下, UE釆用 3G的 GNSS或者 OTDOA辅助定位的 筒化流程如图 5所示, 在连接状态下, UE上报了自身的能力, 基站根据 UE的能力选择其 执行 logged MDT任务, 即在 idle状态下执行 MDT的相关测量。 其中, MDT配置中, 可 以明确指示釆用哪种 inter-RAT的定位方法, 也可以让 UE执行尽力而为( best effort )的定 位测量, 即如果不能使用 GNSS、 A-GNSS以及 OTDOA的方法进行定位的话, 就自动执 行两种无线接入下的 RF finger print测量。相关的测量结果保存到 MDT log文件中。在 UE 进入连接状态后, 将 MDT log上报。
补充说明: 在图 5所示流程中, UE执行定位测量的同时, 如果需要的话, 也会执行 MDT的相关测量。
实施例五:
根据实施例二, 下面给出空闲状态下, UE釆用 RF finger print测量来提供位置信息的 主要流程如图 6所示,在该流程中,数据到达 TCE之后,意味着运营商获取了相关的信息, 运营商可以后台处理数据, 根据 3G的 RF finger print地图以及相关的测量量, 获取 UE的 位置, 并建立 LTE的 RF finger print地图。
在上述流程中, 理论上, 如果 LTE网络是已经部署好的网络, 2G和 3G网络是后部署 的网络, 则 UE也可以执行 LTE的定位, 辅助 2G、 3G网络的部署优化和地图形成。 当然, 这是实际中很少出现的场景。
补充说明: 在图 6所示的流程中, UE执行定位测量的同时, 如果需要的话, 也会执 行 MDT的相关测量。
实施例六:
LTE系统收到 UE上报的 inter-RAT的定位结果或者定位测量结果后,可以使用其形成
LTE的地图, 也可以作为 LTE MDT中使用的位置信息对所在位置进行优化。 例如, UE上 报的 inter-RAT的定位结果, 如经纬度信息, 以及 LTE的 RF finger print测量结果。 OAM 可以将该位置信息与 LTE的 RF finger print测量结果相关联, 并保存在数据库中。 当收集 到足够多的位置信息和 RF finger print的测量结果样本, 就可以形成 LTE RF finger print的 地图数据库。 之后如果只有 LTE的 RF finger print的测量结果上报, 就可以从数据库中查 到与此测量结果想接近的地理位置信息。
如果 UE上报的是 inter-RAT的 RF finger print和 LTE的 RF finger print的测量结果, 则 OAM可以根据 inter-RAT的 RF finger print的地图获取该测量量, 获得其所在的地理位 置信息, 再将此地理位置信息与 LTE的 RF finger print的测量结果进行关联, 形成 LTE的 RF finger print的地图数据库。当获得的地图相对成熟时,就可以用于根据 LTE的 RF finger print测量结果查找 LTE的 RF finger print数据库来获取位置信息。

综上所述, 本发明双模 UE通过另一个 RAT的定位功能来辅助完成 LTE模式的 MDT 功能。 即接收 2G、 3G网络广播的定位辅助数据来进行定位,或者通过对 2G、 3G以及 LTE 系统的网络进行 finger print的测量, 通过 LTE系统的 logged MDT或者 IMM MDT上报给 e B , 再发给 OAM建立 LTE系统 RF finger print地图。
具体地, 在 UE侧:
双模 UE可以在 LTE系统下上报 inter-RAT的定位能力。
双模 UE在 2G或 3G模式下执行定位功能,并将其定位结果通过 LTE模块上报给 LTE 网络。
双模 UE在 LTE的空中接口能够同时上报 2G或 3G, 和 LTE的 RF finger print测量结 果, 即通过 RRC信令上报。
上报 2G或 3G模式下的定位结果时,也可以连同 LTE的 RF finger print测量结果一起 上报。
其定位结果可以是经纬度信息, 也可以是 OTDOA定位的测量结果。
在基站侧:
基站( eNB )根据双模 UE的能力信息选择其执行 MDT任务, 并能够配置该 UE执行 inter-RAT的定位。
基站(eNB )将 UE的 inter-RAT ( 20或30 ) 定位结果或者测量结果上报给 TCE。 基站( eNB )将 UE的 2G或 3G的 RF finger print测量结果连同 LTE的 RF finger print 测量结果一起上报给 TCE。
其中, 基站也可以将 UE的 inter-RAT ( 2G或 3G )定位结果或者测量结果连同 LTE的 RF finger print测量结果一起上 ·ί艮给 TCE。
需要说明的是: 本发明不但适用于双模双待 UE, 也适用于双模单待 UE, 只是双模单 待 UE可能执行测量的时间略长, 定位的精度比双模双待 UE要低一些。
因此, 本发明提供了一种双模 UE执行 MDT时获得位置信息方法, 为执行 LTE MDT 功能提供了更多的获取位置信息的方式。 本发明同时也提供了一种在无法进行 GNSS、
OTDOA等定位方式获取位置信息的情况下, 通过对已有的 inter-RAT RF finger print的测 量以及 LTE网络的 RF finger print的测量来建立 LTE网络的 RF finger print地图的方法, 使得运营商可以在布 LTE网络时, 通过已有的网络的 RF finger print地图建立新建 LTE网 络的 RF finger print地图。
