Description

定位基站确定方法、定位服务器、服务基站以及网络系统 技术领域
本发明涉及移动通信领域，尤其涉及一种确定用于定位终端设备的定位基站的技术。
背景技术
随着通信业务的发展，定位业务作为移动通信和个人通信服务的一个不可或缺的部分，发挥着重要作用。近年来，随着人们物质生活水平的不断提高，人们对位置服务的需求也与日俱增，如在安全监控、紧急救援、出行指南等诸多方面对定位的广泛需求。特别是在紧急救援等特殊应用场景，用户设备(User Equipment，简称UE)的定位信息尤为重要。
在长期演进(Long Term Evolution，简称LTE)系统中，网络设备或UE测量用于定位的参考信号，并根据定位算法对所述测量结果进行计算以得到所述UE的位置坐标，所述测量结果可以包含信号场强、信号到达时间差、以及信号到达方向角中的一种或多种等。
现有技术中，网络设备或者定位服务器接收UE的定位请求，通知UE向所述网络设备或定位服务器上报邻区信息，并根据所述上报的邻区信息选择参与定位的基站。在定位过程中，所述网络设备或定位服务器接收到定位请求后，需要通知UE上报邻区信息，UE响应于所述通知测量并向所述网络设备或定位服务器上报邻区信息。因此，所述网络设备或定位服务器不能及时获取所述邻区信息，导致定位速度较慢，定位效率较低不能满足对定位信息需求较为迫切的场景的需要。
因此，针对上述情况，目前还没有有效的解决方案。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式做出进一步地详细描述。
图1示出了本发明实施例提供的定位基站确定方法所涉及的网络架构。所述网络架构包含基站1、基站2、基站3以及终端设备，以及定位服务器。本发明实施例的技术方案中由所述定位服务器计算所述终端设备的位置。
基于到达时间差(Time Difference of Arrival，简称TDOA)测量的定位算法是重要的定位算法。可观察到达时间差(Observed Time Difference Of Arrival，简称OTDOA)和上行到达时间差(Uplink Time Difference Of Arrival，简称UTDOA)是常见的基于到达时间差测量的定位技术。OTDOA和UTDOA方法均是通过检测信号到达的时间差来确定终端设备的位置。为了获得精确定位，OTDOA/UTDOA方法要求同时有三个以上的基站参与定位参数的测量。下文以OTDOA和UTDOA两种方法为例阐述终端设备的定位方法。
当采用OTDOA定位技术时，定位服务器确定三个或三个以上的基站，并基于由所述基站发送的参考信号到达终端设备的时间差(Reference Signal Time Difference，简称RSTD)计算所述终端设备的位置。具体的，在LTE系统中，演进的服务移动位置中心(Evolved Serving Mobile Location Center，简称E-SMLC)确定参与定位的多个基站，并获取所述多个基站的定位参考信号(Positioning Reference Signaling，简称PRS)配置信息。所述终端设备根据所述参与定位的基站的PRS配置信息，接收并测量所述基站发送的PRS，并将所述测量结果发送给所述E-SMLC，所述E-SMLC基于所述测量结果计算所述终端设备的位置。其中，所述PRS配置信息包括但不限于资源映射(例如资源单元(Resource Element，简称RE)映射)信息、PRS序列初始值(Initial PRS Sequence)、子帧配置(Subframe Configuration)信息、用于定位的基站位置坐标、邻区信息等信息中的一个或多个。其中所述子帧 配置信息可以为用于承载所述PRS的子帧的配置信息。所述终端设备可以通过LTE定位协议(LTE Positioning Protocol，简称LPP)定义的辅助数据消息，从E-SMLC获取参与定位的基站的PRS配置信息。LPP提供的辅助数据消息中可能包括以下信息：
①参考小区信息，包括参考小区的物理小区识别码(Physical Cell Identification，简称PCI)和/或PRS配置信息等信息，参考小区可以是所要定位的终端设备的服务小区，但是并不局限于服务小区，也可以是其他小区，如，服务小区的邻区等；
②邻区列表，包括每个邻区的PCI、PRS配置等信息。邻区信息列表是根据预先对终端设备位置的估计而选取的一些利于测量PRS的邻区。
当采用UTDOA定位技术时，定位服务器确定三个或三个以上的基站，并根据由终端设备向所述基站发送的参考信号到达所述各个基站的时间差RSTD计算所述终端设备的位置。具体的，在LTE系统中，E-SMLC确定参与定位的多个基站，并获取所述终端设备发送的探测参考信号(Sounding Reference Signal，简称SRS)配置信息。所述参与定位的基站根据所述SRS配置信息，接收并测量所述终端设备发送的SRS，并将所述测量结果发送给所述E-SMLC，所述E-SMLC基于所述测量结果计算所述终端设备的位置。其中，所述SRS配置信息包括但不限于资源映射(例如RE映射)信息、SRS序列初始值(Initial SRS Sequence)、子帧配置信息等。其中所述子帧配置信息可以为用于承载所述SRS的子帧的配置信息。所述基站可以通过LPP定义的辅助数据消息，从E-SMLC获取所述终端设备的SRS配置信息。辅助数据消息可能包含的内容参见上文记载，这里不再赘述。
现有的终端设备定位方法中(包括但不限于UTDOA和OTDOA方法)，定位服务器先确定可供选择的基站，并从所述确定可供选择的基站中选择参与定位的基站。一般来说，定位服务器响应于终端设备的定位请求，通知所述终端设备上报相邻基站信息。所述终端设备测量相邻基站或相邻小区信息，将测量结果上报给所述定位服务器。所述定位服务器根据所述测量结果 确定可供选择的基站，并进一步选择参与定位的基站。因此，终端设备测量相邻基站或相邻小区时，定位服务器处于等待状态，延长了定位时间。
本发明实施例提供了一种定位基站确定方法，能够高效选择基站参与定位，提高了定位速度，改善了定位效率。
本发明实施例涉及的终端设备，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(PCS，Personal Communication Service)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL，Wireless Local Loop)站、个人数字助理(PDA，Personal Digital Assistant)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。
本发明实施例所涉及的基站，包括但不限于宏基站、微型基站、微微基站，归属于同一个宏基站的微型射频拉远单元(pico Remote Radio Unit，简称pRRU)与射频拉远单元(Remote Radio Head，简称RRH)等、归属于不同宏基站的pRRU与RRH等中的一个或多个。另外，基站可以是全球移动通信(Global System for Mobile communications，简称GSM)系统或码分多址(Code Division Multiple Access，简称CDMA)系统中的基站，也可以是宽带码分多址(Wideband Code Division Multiple Access Wireless，简称WCDMA)系统中的基站(NodeB)，还可以是LTE中的演进型基站(evolutional Node B，简称eNB或e-NodeB)，本申请并不限定。
本发明实施例所涉及的定位服务器，可以是一个集成在网络设备中的逻辑实体(例如，网络设备中设置的参与定位的网元)或者硬件设备，也可以是独立于基站或者其他网络设备的网元设备，本申请并不限定。
本发明实施例所提供的终端设备定位方法中，网络设备和终端设备之间需要利用选定的资源传输参考信号。其中，所述资源可以由网络设备分配，也可以由终端设备在网络设备分配的资源池中选择，所述资源可以是时频上的任意资源。
下面结合图2对本发明实施例提供的定位基站确定方法进行描述。
S201：定位服务器从终端设备接收定位请求消息。
S202：所述定位服务器根据所述定位请求消息从服务基站获取可选基站信息，其中，所述服务基站为所述终端设备的服务基站，所述可选基站信息指示至少一个基站。

本发明实施例提供了一种定位基站的确定方法，定位服务器可以直接从服务基站获取可选基站信息，进而确定用于定位的定位基站集合。采用本发明实施例所提供的定位基站的确定方法，定位服务器可以及时获取可选基站信息，节约了定位时间，提高了定位效率。
需要说明的是，本发明实施例中的服务基站，可以是负责和终端设备直接通信的一个基站或一组基站。例如，若终端设备支持载波聚合技术，服务基站可以是每个载波对应的基站。又如，服务基站也可以是用于寻找终端设备的一组基站，若终端设备处于闲置状态，未与基站进行通信，当网络系统需要唤醒处于闲置状态的所述终端设备时，一个或多个基站用于尝试联系所述终端设备，该一个或多个基站在本发明实施例中也被视做服务基站。
为了避免引起歧义，本发明所有实施例中可以将服务基站称为第一基站，将所述可选基站信息指示的所述至少一个基站称为第二基站。

又一可选的实施例中，所述可选基站信息包含至少一个基站的标识以及至少一个相邻小区的标识。所述至少一个基站包含所述服务基站和/或所述终端设备的相邻基站，所述至少一个相邻小区包含所述终端设备的相邻小区。所述服务基站获取所述相邻基站和所述相邻小区的信息，保存为可选基站信 息，所述可选基站信息至少包含所述至少一个基站的标识以及所述至少一个小区的标识。
具体的，所述服务基站获取所述相邻基站和所述相邻小区的信息的方式可以参见上述可选的实施例中的记载，这里不再赘述。
在该可选的实施例中，所述服务基站中存储的可选基站信息包含至少一个相邻小区的信息。所述服务基站将所述可选基站信息上报给所述定位服务器，所述定位服务器则根据所述至少一个相邻小区的信息，确定所述至少一个相邻小区的基站的信息。具体的，所述服务基站可以基于现有技术中的多种方式，通过所述相邻小区的标识获取相邻小区的基站信息。例如，服务基站可以通过基站之间的通信接口(例如，e-NodeB之间的通信接口X2)向周边基站发送查询指令，所述相邻小区的基站响应于所述查询指令，向所述服务基站反馈所述相邻小区的基站标识。
步骤S203中，所述定位服务器根据所述可选基站信息确定定位基站集合。由于本发明实施例中用于指示至少一个基站的所述可选基站信息可以包含至少一个基站的标识和/或至少一个相邻小区的标识。因此在确定所述定位基站集合之前，所述定位服务器需要根据所述可选基站信息确定可选的基站的信息。
当所述可选基站信息包含至少一个基站的标识时，所述定位服务器根据所述至少一个基站的标识确定所述定位基站集合。
当所述可选基站信息包含至少一个相邻小区的标识时，所述定位服务器则根据至少一个相邻小区的标识确定所述定位基站集合。具体的，所述定位服务器可以根据所述至少一个相邻小区的标识确定所述至少一个相邻小区对应的至少一个基站的信息，然后根据所述至少一个基站的信息确定所述定位基站集合。
具体的，所述定位服务器根据所述可选基站信息包含的至少一个基站的信息确定所述定位基站集合可以通过多种方式实现。
例如，一种实现方式中，所述至少一个基站的信息至少包含所述至少一 个基站的标识。所述定位服务器可以根据所述至少一个基站的标识，对所述至少一个基站发送请求消息。所述请求消息用于请求所述至少一个基站反馈基站坐标、基站负载、基站定位参考信号配置情况等信息中的至少一个，所述至少一个基站响应于所述请求消息，反馈相应的信息。所述定位服务器根据所述至少一个基站反馈的信息决定参与定位的基站。
进一步的，所述请求消息还用于请求所述至少一个基站反馈相邻基站或相邻小区信息，所述至少一个基站响应于所述请求消息，反馈相应信息。所述定位服务器根据所述反馈信息，获取更多的可用于所述终端设备定位的基站。所述定位服务器可以对所述至少一个基站反馈的相邻基站或相邻小区的基站发送请求消息，所述请求消息用于请求获取所述相邻基站或相邻小区的相邻基站或相邻小区，以获得更多的可用于所述终端设备定位的基站。该步骤为所述定位服务器提供了更多用于终端设备定位的可选基站，使得所述定位服务器可以确定最合适的一定数量的基站进行所述终端设备的定位。
又如，另一实现方式中，所述至少一个基站的信息至少包含所述至少一个基站的标识以及所述至少一个基站的状态信息，所述的定位服务器根据所述至少一个基站的标识和所述状态信息确定定位基站集合。
可选的，所述至少一个基站的状态信息可以包含所述终端设备的接收功率，所述定位服务器可以根据所述接收功率，选择所述至少一个基站和所述服务基站中前N个接收功率较大的基站作为定位基站，确定定位基站集合，所述N为正整数。
可选的，所述至少一个基站的状态信息可以包含基站估计的路损、基站坐标、基站定位参考信号配置情况、基站负载、基站接收功率、基站接收上下行信号时间等信息中的至少一个。所述定位服务器可以根据上述状态信息中的一个或多个，选择N个合适的基站作为定位基站，确定定位基站集合，所述N为正整数。
在该实现方式中，所述可选基站信息指示的至少一个基站的状态信息可以由所述服务基站发送给所述定位服务器。该状态信息可以与所述至少一个 基站的标识同时由所述服务基站发送到所述定位服务器，也可以单独由所述服务基站发送到所述定位服务器。例如，所述服务基站可以先发送所述至少一个基站的标识给所述定位服务器，响应于所述定位服务器对所述至少一个基站的状态信息的需求，所述服务基站获取所述至少一个基站的状态信息并将所述状态信息发送到所述定位服务器；或者，所述服务基站根据所述至少一个基站的标识，自动获取所述至少一个基站的状态信息，同时将所述标识和状态信息，或者独立地将所述标识和状态信息发送到所述定位服务器。对于所述服务基站获取所述至少一个基站的状态信息的方式，现有技术中存在多种实现，这里不再赘述。
对于以上任一种实施例或者实现方式，需要说明的是，对于OTDOA、UTDOA等定位方法，需要三个或三个以上的定位基站。因此，所述可选基站信息需要指示至少两个基站。所述定位服务器根据所述可选基站信息，确定M个定位基站，所述M大于或等于3。
例如，所述M个定位基站包括所述可选基站信息指示的至少两个基站中的至少两个以及所述服务基站。
又如，所述可选基站信息指示至少三个基站，所述N个定位基站包括所述可选基站信息指示的至少三个基站中的至少三个。

下面以OTDOA和UTDOA方法为例，分别描述应用本发明实施例提供的定位基站确定方法的终端设备定位方法。
在一实现方式中，将本发明实施例提供的定位基站确定方法应用到OTDOA定位方法中。定位流程如图6所示，具体流程如下：
S601：终端设备发送定位请求消息给定位服务器，所述定位服务器接收定位请求消息；该步骤为可选步骤。
S602：定位服务器向所述终端设备的服务基站发送指示信息；
S603：所述服务基站接收并响应所述指示信息，获取可选基站信息，所述服务基站向所述定位服务器发送所述可选基站信息；
S604：所述定位服务器根据所述可选基站信息，确定用于所述终端设备定位的定位基站集合，并通知所述定位基站集合中的基站1-n向所述终端设 备发送PRS；
具体的，所述定位服务器向所述终端设备发送辅助数据消息，所述辅助数据消息指示所述PRS配置信息，以供所述终端设备接收并测量所述下行参考信号。所述PRS配置信息包括但不限于资源映射(例如资源单元(Resource Element，简称RE)映射)信息、PRS序列初始值(Initial PRS Sequence)、子帧配置(Subframe Configuration)信息、用于定位的基站位置坐标、邻区信息等信息中的一个或多个。
S605：所述定位基站集合中的各个基站发送PRS；

S607：所述定位服务器根据所述终端设备上报的RSTD测量值，计算得到所述终端设备的位置坐标。
具体的，OTDOA定位方法中，通过检测至少三个不同基站发送的PRS到达终端设备的时间差来确定所述终端设备的位置。具体算法可以为：所述终端设备位于以两个基站为焦点的双曲线上,获取所述终端设备的坐标为(x，y)，基站i的位置坐标为(xi，yi)，基站i发送信号的时间为Ti，所述终端设备接收到该PRS的时间为ti。建立两个以上的双曲线方程，两条双曲线的交点为所述终端设备的二维位置坐标。求解方程组即可得所述终端设备的二维地理坐标。
在另一实现方式中，将本发明实施例提供的定位基站确定方法应用到UTDOA定位方法中。定位流程如图7所示，具体流程如下：
S701：终端设备发送定位请求消息给定位服务器，所述定位服务器接收定位请求消息；该步骤为可选步骤。

S703：所述服务基站接收并响应所述指示信息，获取可选基站信息，所述服务基站向所述定位服务器发送所述可选基站信息；

S705：所述终端设备向所述定位集合中的各个基站1-n发送SRS；
S706：所述各个基站测量并记录所述SRS的到达时间，并上报给所述定位服务器；
S707：所述定位服务器接收所述到达时间，计算所述每两个基站的SRS到达时间差RSTD，计算得到所述终端设备的位置坐标。
具体的，所述UTDOA定位方法中计算终端设备位置的具体算法可以参见上文中的OTDOA定位方法中的位置计算算法，这里不再赘述。
在上述UTDOA/OTDOA定位方法中，定位服务器直接从服务基站获取可选基站信息，并用于进行定位的定位基站集合的确定，节约了定位时间，提高了定位效率。
