Description

一种LMU的选择方法及相关设备
本申请要求于2016年09月07日提交中国专利局、申请号为201610807850.1、发明名称为“一种LMU的选择方法及相关设备”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
本发明涉及定位技术领域，具体涉及一种位置测量单元(location measurement unit，LMU)的选择方法及相关设备。
背景技术
移动定位业务(location service，LCS)是一种根据用户所在的位置信息提供的增值业务，它是在全球移动通信系统(global system for mobile communication，GSM)标准规范的发展过程中提出的，指电信运营商或者第三方业务提供商利用用户设备(user equipment，UE)可得到的位置信息所提供的业务，LCS处于全球电信市场的竞争的需要，能够有效提供电信运营商的竞争力。
其中，在R11协议中提出了一种上行到达时间差(uplink time difference of arrival，UTDOA)定位算法，UTDOA定位算法利用UE的参考信号，例如：探测参考信号(sounding reference signal，SRS)，对UE本身没有要求，由无线LMU进行SRS测量，然后将SRS的测量数据上报给演进的定位服务中心(evolved serving mobile location centre，E-SMLC)，E-SMLC根据测量数据进行定位。如图1所示，为LCS定位系统的一个结构示意图，整个定位过程为：
1、LCS客户端发起定位请求，并将定位请求发送到与LCS客户端连接的网关移动位置中心(gateway mobile location center，GMLC)。
2、GMLC通过查询归属用户服务器(home subscriber server，HSS)得到UE当前接入的移动管理实体(Mobile Managenment Entity，MME)，然后GMLC将定位请求发送给UE当前接入的MME。
3、MME接收到定位请求后，向E-SMLC转发该定位请求。
4、E-SMLC接收到定位请求后，选择UTDOA定位算法，向基站(eNodeB)发起定位测量请求。
5、eNodeB接收到定位测量请求后，配置UE的SRS，将SRS下发给UE，同时返回SRS给E-SMLC，UE接收到SRS后，开始进行SRS广播。
6、E-SMLC收到eNodeB返回的SRS，选择进行SRS测量的目标LMU，并向选择的目标LMU发起定位测量请求。
7、目标LMU将测量数据返回给E-SMLC。
8、E-SMLC根据测量数据进行位置计算，将UE的位置计算结果返回给MME。
9、MME接收到UE的位置计算结果后，将UE的位置计算结果返回GMLC。
10、GMLC将UE的位置计算结果上报给LCS客户端，定位流程结束。
在E-SMLC选择目标LMU时，要求选择合适的LMU进行UE的SRS测量，一般而言，LMU信噪比越高，距离UE越近，LMU测量的数据越准确，定位精度越高。当前协议上要求LMU向E-SMLC发送LMU的位置信息、LMU支持的带宽信息，如表一所示。
Figure PCTCN2017099632-appb-000001
表一
同时，E-SMLC还需要静态配置UE当前所在小区的位置信息，例如：演进的通用陆地无线接入网(evolved universal terrestrial radio access network，E-UTRAN)小区全局标识(E-UTRAN cell global identifier，ECGI)、外设互联标准(Personal Computer Interface，PCI)信息等。
E-SMLC选择合适的LMU时，根据LMU的位置信息和UE当前所在小区的位置信息，并根据距离远近对LMU进行排序，选择较近的LMU作为目标LMU进行SRS测量。由于移动网络中LMU的规格和小区的规格都很大，达到数万到数十万的规格，在海量数据中进行距离计算来确定目标LMU，整个过程计算量大，从而影响LMU的选择效率。
发明内容
本发明实施例提供了一种LMU的选择方法及相关设备，用于解决现有LMU的选择过程所存在的计算量大的问题，整个选择目标LMU的过程计算量小，从而有效提高LMU的选择效率。
本发明第一方面提供一种LMU的选择方法，该方法应用于移动定位业务LCS定位系统，该LCS定位系统中至少包括第一网络设备，该第一网络设备首先获取用户设备UE当前所在的目标小区，再确定该目标小区对应的第一位置测量单元LMU，然后确定与该目标小区相邻的邻接小区对应的第二LMU，这样，该第一网络设备就可以直接选择第一LMU和第二LMU 作为目标LMU。
与现有技术不同的是，在获取UE当前所在的目标小区后，并非根据目标小区的位置信息和LMU的位置信息确定目标LMU，而是确定该目标小区对应的第一LMU以及与该目标小区相邻的邻接小区对应的第二LMU，则直接选择该第一LMU和该第二LMU作为目标LMU。这样，整个选择目标LMU的过程计算量小，从而有效提高LMU的选择效率。
在一些可能的实现方式中，在第一网络设备确定与目标小区相邻的邻接小区对应的第二LMU之前，该第一网络设备获取该目标小区的位置信息以及小区邻接关系表，然后根据该目标小区的位置信息从该小区邻接关系表中获取与该目标小区相邻的邻接小区。
与现有技术不同的是，无需在第一网络设备上配置小区的位置信息，而是第一网络设备获取小区邻接关系表，第一网络设备根据该目标小区的位置信息从获取的小区邻接关系表中直接获取与该目标小区相邻的邻接小区，计算量少，简单便捷。
在实际应用中，第一网络设备获取小区邻接关系表的方式有很多种，下面介绍可能实现的几种获取方式：
第一种获取方式为：第一网络设备从第二网络设备获取小区邻接关系表，其中，该小区邻接关系表配置在第二网络设备上。可见，无需在第一网络设备上配置小区的位置信息，而是第一网络设备通过第二网络设备获取小区邻接关系表，从而减少了第一网络设备的配置工作量。
第二种获取方式为：第一网络设备从本地获取小区邻接关系表，其中，该小区邻接关系表配置在所述第一网络设备上。在实际应用中，第一网络设备是通过其他的设备将该小区邻接关系表配置在该第一网络设备上，从而减少了第一网络设备的配置工作量。
在一些可能的实现方式中，第一网络设备确定目标小区对应的第一LMU之前，第一网络设备获取N个LMU的N个位置信息和配置在N个LMU上的N个小区的N个位置信息，其中，N为大于0的整数，这样，第一网络设备根据N个LMU的N个位置信息和N个小区的N个位置信息确定小区与LMU之间的对应关系。在实际应用中，该小区与LMU之间的对应关系可以以列表的形式本地保存，便于后续查找。则后续第一网络设备直接根据小区与LMU之间的对应关系确定目标小区对应的第一LMU，第一网络设备直接根据小区与LMU之间的对应关系确定与目标小区相邻的邻接小区对应的第二LMU，其中，该第二LMU至少有一个。
可见，不需要在第一网络设备上静态配置数据，从而节省大量维护工作量，减少维护难度，提高了网络变更时数据更新的实时性。同时，不需要根据距离计算来选择第一LMU或者第二LMU，从而减轻了第一网络设备的计算工作量，降低第一网络设备的性能消耗。
在一些可能的实现方式中，第一网络设备从第三网络设备获取LMU邻接关系表，然后根据所述第一LMU从所述LMU邻接关系表获取与该目标小区相邻的邻接小区对应的第二LMU。
可见，该第一网络设备直接根据该LMU邻接关系表获取与第一LMU相邻的第二LMU，从而有效节省了第一网络设备的配置工作量，然后第一网络设备直接选择UE当前所在的目标小区对应的第一LMU和与该目标小区相邻的邻接小区对应的第二LMU作为该目标LMU，整个选择目标LMU的过程计算量小，从而有效提高LMU的选择效率。
本发明第二方面提供一种网络设备，该网络设备为LCS定位系统中的第一网络设备，该第一网络设备被配置实现上述第一方面提供的方法的功能。该功能可以通过硬件实现，也可以通过硬件执行相应的软件实现，该硬件或软件包括一个或多个与上述功能相对应的模块。
本发明第三方面提供一种网络设备，该网络设备为LCS定位系统中的第一网络设备，该第一网络设备包括有线或者无线网络接口、存储器、处理器，其中，存储器中存储一个或多个程序，该存储器用于向处理器提供该一个或多个程序包括的操作指令和数据，该处理器执行该存储器中存储的程序用于实现上述第一方面提供的方法中的步骤。

请参阅图4，为本发明实施例中LMU的选择方法的一个实施例示意图，该方法应用于LCS定位系统，该LCS定位系统包括第一网络设备和第二网络设备，该实施例的具体流程如下：
步骤401、第一网络设备获取UE当前所在的目标小区。
本发明实施例中，该第一网络设备可以是E-SMLC，该目标小区为用于定位的UE当前所在的小区。在实际应用中，E-SMLC从MME获取对UE的定位请求，E-SMLC选择UTDOA定位算法向基站发送定位测量请求，则基站根据接收到的定位测量请求配置UE的SRS，并将配置的SRS下发给UE以及返回给E-SMLC，E-SMLC根据SRS选择进行SRS测量的目标LMU，则在选择目标LMU之前，需要获取UE当前所在的目标小区。
步骤402、第一网络设备获取N个LMU的N个位置信息和配置在N个LMU上的N个小区的N个位置信息，其中，N为大于0的整数。
与现有技术不同的是，无需在第一网络设备(例如：E-SMLC)配置小区的位置信息，而是在LMU上配置小区的位置信息，从而减少了E-SMLC的配置数据的工作量。其中，该小区的位置信息包括ECGI、PCI及频点等信息。
步骤403、第一网络设备根据N个LMU的N个位置信息和N个小区的N个位置信息确定小区与LMU之间的对应关系。
本发明实施例中，第一网络设备根据获取的N个LMU的N个位置信息和N个小区的N个位置信息提前确定好小区与LMU之间的对应关系，在实际应用中，该第一网络设备还可以将确定的小区与LMU之间的对应关系以列表的形式进行本地保存，便于后续查找使用。
在实际应用中，在LMU上配置ECGI、POI及频点等信息，如下表二：
Figure PCTCN2017099632-appb-000002
表二
进一步，E-SMLC确定LMU和无线小区的位置信息(ECGI、PCI及频点等信息)之间的绑定关系，在LMU接入到E-SMLC时，将这个绑定关系携带给E-SMLC。
步骤404、第一网络设备根据所述小区与LMU之间的对应关系确定目标小区对应的第一LMU。
本发明实施例中，由于第一网络设备提前确定小区与LMU之间的对应关系，则当确定UE当前所在的目标小区后，则直接根据小区与LMU之间的对应关系确定该目标小区对应的第一LMU，其中，该第一LMU为目标小区对应的LMU。
步骤405、第一网络设备获取目标小区的位置信息。
本发明实施例中，当确定目标小区对应的第一LMU后，还需要确定与该目标小区相邻的邻接小区对应的第二LMU，其中，在确定与该目标小区相邻的邻接小区对应的第二LMU之前，先确定该目标小区的位置信息，便于根据该目标小区的位置信息确定与该目标小区 相邻的邻接小区。
步骤406、第一网络设备从第二网络设备获取小区邻接关系表，其中，该小区邻接关系表配置在第二网络设备上。
与现有技术不同的是，无需在第一网络设备上配置小区的位置信息，而是第一网络设备通过第二网络设备获取小区邻接关系表，由于在第二网络设备上提前配置有小区邻接关系表，其中，该第二网络设备可以是基站，以第一网络设备为E-SMLC为例，E-SMLC直接从基站获取该目标小区对应的小区邻接关系表。
步骤407、第一网络设备根据目标小区的位置信息从小区邻接关系表中获取与目标小区相邻的邻接小区。
本发明实施例中，第一网络设备根据该目标小区的位置信息从获取的小区邻接关系表中直接获取与该目标小区相邻的邻接小区，计算量少，简单便捷。
步骤408、第一网络设备根据小区与LMU之间的对应关系确定与目标小区相邻的邻接小区对应的第二LMU。
本发明实施例中，第一网络设备直接根据提前确定的小区与LMU之间的对应关系确定与该目标小区相邻的邻接小区对应的第二LMU，其中，该第二LMU为该邻接小区对应的LMU，该第二LMU至少有一个。
步骤409、第一网络设备选择第一LMU和第二LMU作为目标LMU。
本发明实施例中，第一网络设备直接选择UE当前所在的目标小区对应的第一LMU和与该目标小区相邻的邻接小区对应的第二LMU作为该目标LMU，整个选择目标LMU的过程计算量小，从而有效提高LMU的选择效率。
如图5a所示，在实际应用中，以第一网络设备为E-SMLC为例，在LMU上配置LMU的标识码、LMU的位置信息、LMU的能力集以及归属小区的ECGI、PCI及频点等信息，LMU通过创建请求(SLm Setup Request)的方式接入到E-SMLC时，其中，该SLm Setup Request中包括小区位置信息，例如：ECGI、PCI、频点等信息。
E-SMLC从SLm Setup Request中获取LMU的位置信息及配置在LMU上的小区的位置信息，若E-SMLC对UE进行定位，则E-SMLC从第二网络设备(例如：基站)获取UE当前所在的目标小区的小区邻接关系表，在实际应用中，该小区邻接关系表以预设的顺序形成列表，便于后续查找。如图5b所示，E-SMLC在通过UTDOA定位算法选择目标LMU时，直接选择UE当前所在的目标小区对应的LMU及与与该目标小区相邻的邻接小区对应的LMU，将这些LMU作为用于定位测量的目标LMU。
可见，在LMU接入E-SMLC时，LMU主动向E-SMLC上报LMU的位置信息及配置在LMU上的小区的位置信息，在定位过程中，E-SMLC直接从基站获取UE当前所在的目标小区的小区邻接关系表，则不需要在E-SMLC上静态配置数据，从而节省大量维护工作量，减少维护难度，提高了网络变更时数据更新的实时性。同时，不需要根据距离计算来选择目标LMU，从而减轻了E-SMLC的计算工作量，降低E-SMLC的性能消耗。
请参阅图6，为本发明实施例中LMU的选择方法的另一个实施例示意图，该方法应用于LCS定位系统，该LCS定位系统包括第一网络设备，该实施例的具体流程如下：
步骤601、第一网络设备获取UE当前所在的目标小区。
步骤602、第一网络设备获取N个LMU的N个位置信息和配置在N个LMU上的N个小区的N个位置信息，其中，N为大于0的整数。
步骤603、第一网络设备根据N个LMU的N个位置信息和N个小区的N个位置信息确定小区与LMU之间的对应关系。
步骤604、第一网络设备根据所述小区与LMU之间的对应关系确定目标小区对应的第一LMU。
步骤605、第一网络设备获取目标小区的位置信息。
步骤606、第一网络设备从本地获取小区邻接关系表，其中，该小区邻接关系表配置在第一网络设备上。
与图4所示实施例不同的是，第一网络设备从本地获取该小区邻接关系表，在实际应用中，是通过其他的设备将该小区邻接关系表配置在该第一网络设备上，从而减少了第一网络设备的配置工作量。
步骤607、第一网络设备根据目标小区的位置信息从小区邻接关系表中获取与目标小区相邻的邻接小区。
步骤608、第一网络设备根据小区与LMU之间的对应关系确定与目标小区相邻的邻接小区对应的第二LMU。
步骤609、第一网络设备选择第一LMU和第二LMU作为目标LMU。
需要说明的是，步骤601至步骤605以及步骤607至步骤609与图4所示的步骤401至步骤405以及步骤407至步骤409相同或者相似，具体可参阅步骤401至步骤405以及步骤407至步骤409的描述，此处不再赘述。
如图7所示，在实际应用中，以第一网络设备为E-SMLC为例，在LMU上配置LMU的标识码、LMU的位置信息、LMU的能力集以及归属小区的ECGI、PCI及频点等信息，LMU通过SLm Setup Request的方式接入到E-SMLC时，其中，该SLm Setup Request中包括ECGI、PCI、频点等信息，E-SMLC从SLm Setup Request中获取LMU的位置信息及配置在LMU上的小区的位置信息。通过运营支撑系统(The Office of Strategic Services，OSS)在E-SMLC上配置小区间的小区邻接关系表。
若E-SMLC对UE定位，则E-SMLC根据UE当前所在的目标小区，从配置多个小区的小区邻接关系表中查找UE当前所在的目标小区的小区邻接关系表，则选择目标LMU时直接选择UE当前所在的目标小区对应的LMU及与该目标小区相邻的邻接小区对应的LMU，将这些LMU作为定位测量的目标LMU。
可见，在LMU接入E-SMLC时，LMU主动上报LMU的位置信息及小区的位置信息，通过OSS在E-SMLC上配置系统内的小区间的小区邻接关系表，能够节省静态数据配置的工作量，节省维护工作量。另外，不需要根据距离计算来选择目标LMU，从而减轻了E-SMLC的计算工作量，降低了E-SMLC的性能消耗。
请参阅图8，为本发明实施例中LMU的选择方法的一个实施例示意图，该方法应用于LCS定位系统，该LCS定位系统包括第一网络设备和第三网络设备，该实施例的具体流程 如下：
步骤801、第一网络设备获取用户设备UE当前所在的目标小区。
步骤802、第一网络设备确定目标小区对应的第一LMU。
在实际应用中，该第一网络设备可以根据该目标小区的位置信息，选取离该目标小区距离比较近的LMU作为该第一LMU。当然，在实际应用中，还可以通过其他方式确定该目标小区对应的第一LMU，此处不做具体限定。
步骤803、第一网络设备从第三网络设备获取LMU邻接关系表。
与图4和图6所示实施例不同的是，无需确定小区与LMU之间的对应关系，当确定该目标小区对应的第一LMU后，直接从第三网络设备获取该LMU邻接关系表，即获取与该第一LMU相邻的第二LMU，该第二LMU至少有一个。
步骤804、第一网络设备根据所述第一LMU从LMU邻接关系表获取与目标小区相邻的邻接小区对应的第二LMU。
本发明实施例中，该第一网络设备直接根据该LMU邻接关系表获取与第一LMU相邻的第二LMU，从而有效节省了第一网络设备的配置工作量。
步骤805、第一网络设备选择第一LMU和第二LMU作为目标LMU。
本发明实施例中，第一网络设备直接选择UE当前所在的目标小区对应的第一LMU和与该目标小区相邻的邻接小区对应的第二LMU作为该目标LMU，整个选择目标LMU的过程计算量小，从而有效提高LMU的选择效率。
如图9所示，在实际应用中，以第一网络设备为E-SMLC为例，在LMU上配置LMU的标识码、LMU的位置信息、LMU的能力集以及小区归属的ECGI、PCI及频点等信息，在LCS定位系统中部署额外的第三网络设备，例如：邻接关系学习服务器，用于搜集LMU的位置信息、归属小区的ECGI、PCI及频点等信息，并自学LMU邻接关系，形成全网LMU间的LMU邻接关系表。
LMU通过SLm Setup Request接入到E-SMLC，E-SMLC本地存储LMU的位置信息。若E-SMLC在对UE定位，选择目标LMU，则E-SMLC直接从邻接关系学习服务器获取与UE所在的目标小区相邻的邻接小区对应的LMU，将这些LMU作为定位测量的目标LMU。
可见，在LCS定位系统种新增额外的邻接关系学习服务器来搜集维护LMU邻接关系，节省E-SMLC的维护工作量，也减轻了E-SMLC的计算工作量，降低E-SMLC的性能消耗。
为便于更好的实施本发明实施例的上述相关方法，下面还提供用于配合上述方法的相关设备。
请参阅图10，为本发明实施例中第一网络设备1000的一个结构示意图，该第一网络设备为LCS定位系统中的网络设备，该第一网络设备1000包括获取模块1100，确定模块1200，选择模块1300。
获取模块1100，用于获取用户设备UE当前所在的目标小区；
确定模块1200，用于确定所述目标小区对应的第一位置测量单元LMU；
所述确定模块1200，还用于确定与所述目标小区相邻的邻接小区对应的第二LMU；
选择模块1300，用于选择所述确定模块1200确定的所述第一LMU和所述第二LMU作 为目标LMU。
在一些可能的实现方式中，所述获取模块1100，还用于所述确定模块1200确定与所述目标小区相邻的邻接小区对应的第二LMU之前，获取所述目标小区的位置信息；获取小区邻接关系表；根据所述目标小区的位置信息从所述小区邻接关系表中获取与所述目标小区相邻的邻接小区。
在一些可能的实现方式中，所述获取模块1100具体用于从第二网络设备获取所述小区邻接关系表，其中，所述小区邻接关系表配置在所述第二网络设备上。
在一些可能的实现方式中，所述获取模块1100具体用于从本地获取所述小区邻接关系表，其中，所述小区邻接关系表配置在所述第一网络设备上。
在一些可能的实现方式中，
所述获取模块1100，还用于所述确定模块确定所述目标小区对应的第一LMU之前，获取N个LMU的N个位置信息和配置在所述N个LMU上的N个小区的N个位置信息，其中，N为大于0的整数；
所述确定模块1200，还用于根据所述N个LMU的N个位置信息和所述N个小区的N个位置信息确定小区与LMU之间的对应关系。
在一些可能的实现方式中，所述确定模块1200具体用于根据所述小区与LMU之间的对应关系确定所述目标小区对应的第一LMU。
在一些可能的实现方式中，所述确定模块1200具体用于根据所述小区与LMU之间的对应关系确定与所述目标小区相邻的邻接小区对应的第二LMU。
在一些可能的实现方式中，所述确定模块具体用于从第三网络设备获取LMU邻接关系表；根据所述第一LMU从所述LMU邻接关系表获取与所述目标小区相邻的邻接小区对应的第二LMU。
与现有技术不同的是，在获取模块1100获取UE当前所在的目标小区后，确定模块1200并非根据目标小区的位置信息和LMU的位置信息确定目标LMU，而是确定该目标小区对应的第一LMU以及与该目标小区相邻的邻接小区对应的第二LMU，则选择模块1300直接选择该第一LMU和该第二LMU作为目标LMU。这样，选择目标LMU的过程计算量小，从而有效提高LMU的选择效率。
