为了解决现有技术中接入同一个基站的待定位终端只能返回同一个位置信息，导致基于基站的定位不准确的问题，本发明实施例提出了一种基于基站的定位方法，包括：获取待定位终端所接入基站的当前基站标识；根据所述当前基站标识，获取所述当前基站标识对应的常用位置信息集合；根据所述待定位终端前一次上传的位置信息从获取的常用位置信息集合中选取符合预定条件的常用位置信息以作为所述待定位终端的即时位置信息。本发明实施例有效地提高了基于基站的定位精度，提升用户体验。
图1示意性示出了本发明一个实施例的基于基站的定位方法的流程示意图。
参照图1，本发明实施例的基于基站的定位方法包括以下步骤：
步骤S11、获取待定位终端所接入基站的当前基站标识。
需要说明的是，本实施例中的待定位终端为智能手表、智能手环等智能设备，当然，还可为其他具有基于基站进行定位功能的智能设备和移动终端，如手机、平板电脑、掌上电脑PDA或笔记本等，本发明对此不加以限制。
其中，当前基站标识为待定位终端当前接入的基站对应的基站标识，所述基站标识用于唯一标示基站。具体的，所述基站标识可以为基站的身份标识码(Identity，简称id)、硬件地址(Media Access Control，简称MAC)等信息中的一种或多种。
步骤S12、根据所述当前基站标识，获取所述当前基站标识对应的常用位置信息集合。
需要说明的是，本实施例中的常用位置信息集合为针对具体基站的常用位置信息的集合，可包括一个或多个具体的位置信息。具体的，常用位置信息可以为待定位终端经常活动或停留的地点对应的位置信息。
在具体实现中，常用位置信息集合中的常用位置信息，可采用实际的位置坐标，也可采用实际的位置坐标对应的标志性的建筑物名称的方式实现。
需要说明的是，上面提到的常用位置信息集合中的常用位置信息的实现方式仅是举例，除了上述情况之外还可以包括其他的情况。本发明不需要对具体根据怎样的模式实现常用位置信息的具体表现形式进行限定，本领域技术人员需要根据实际应用进行设置。
在一个具体示例中，如，对于一个学龄儿童，其所述具有的智能手表即作为待定位终端。其可以对应有多个常用的基站，每一常用的基站均对应有常用位置信息集合。例如，从家到学校的路上，可能会经过家-早餐店-公园-少年宫-图书大厦-学校。其中，家、早餐店和公园组成第一基站对应的常用位置信息集合，少年宫、图书大厦和学校组成第二基站对应的常用位置信息集合。

需要说明的是，所述即时位置信息即对待定位终端进行定位时对应的实时位置信息。
在具体实现中，服务端会不断的对待定位终端进行定位，当待定位终端处于室外时，可优先通过GPS对待定位终端进行定位，当待定位终端处于室内时，可优选通过wifi对待定位终端进行定位，进而保证在有GPS信号或wifi时，优先采用定位精度高的方式实现对待定位终端的定位。当由于信号问题，无法通过GPS信号或wifi
进行定位时，从待定位终端前一次上传的位置信息中获取终端当前接入基站的基站标识，进而确定该基站标识对应的常用位置信息集合，并根据待定位终端前一次上传的位置信息从获取的常用位置信息集合中选取符合预定条件的常用位置信息以作为所述待定位终端的即时位置信息。进而保证在无法通过GPS信号或wifi进行定位时，能够通过基站对待定位终端进行准确的定位。
本发明实施例提供的基于基站的定位方法，通过获取待定位终端所接入基站的当前基站标识，根据当前基站标识，获取当前基站标识对应的常用位置信息集合，并根据待定位终端前一次上传的位置信息从获取的常用位置信息集合中选取符合预定条件的常用位置信息以作为待定位终端的即时位置信息，解决了接入同一个基站的待定位终端只能返回同一个位置信息的问题，有效地提高了基于基站的定位精度。

图3示意性示出了本发明另一实施例的基于基站的定位方法的流程示意图。
参照图3，本发明实施例的基于基站的定位方法包括以下步骤：
步骤S31、根据所述待定位终端的历史定位信息，确定所述待定位终端对应的基站标识以及与所述基站标识相关的常用位置信息集合。
在具体应用中，服务端通过根据所述待定位终端的历史定位信息，可以得到待定位终端的运动轨迹信息，进而通过对历史定位信息的学习，确定待定位终端对应的常用的一个或多个基站的基站标识以及与每一基站标识相关的常用位置信息集合。
步骤S32、根据所述待定位终端对应的基站标识以及与所述基站标识相关的常用位置信息集合建立所述预设映射关系。
步骤S33、获取待定位终端所接入基站的当前基站标识。
步骤S34、根据所述当前基站标识查找预设映射关系，以获取

根据本发明的一个优选实施例，所述待定位终端的历史定位信息中包括多个历史位置信息以及每一历史位置信息相关的基站标识。
进一步地，所述步骤S31，如图4所示，具体包括以下步骤：
步骤S311、根据所述待定位终端的历史定位信息中基站标识出现的频率，确定所述待定位终端对应的基站标识。
在本发明的一个可选实施例，步骤S311具体包括：从所述待定位终端的历史定位信息中选取出现频率大于预设频率的基站标识，并将选取的基站标识作为所述待定位终端对应的基站标识。
在本发明的一个可选实施例，步骤S311具体包括：从所述待定位终端的历史定位信息中按照基站标识出现频率从高到低的顺序依次选取预设数量的基站标识，并将选取的基站标识作为所述待定位终端对应的基站标识。
步骤S312、对所述待定位终端对应的基站标识相关的历史位置信息进行聚类，得到与所述待定位终端对应的基站标识相关的常用位置信息集合。
在实际用于中，根据步骤S311，可以根据待定位终端的历史定位信息中基站标识出现的频率，确定出待定位终端对应的所有基站标识，但是，其中每一基站标识可能对应有多个相关的历史位置信息，为了保证基于基站的定位的准确性，本步骤中，通过对待定位终端对应的基站标识相关的历史位置信息进行基于密度的聚类，并通过对位置信息进行加权平均，进而准确的得到与所述待定位终端对应的基站标识相关的常用位置信息集合。
本发明实施例，首先根据所述待定位终端的历史定位信息中基站标识出现的频率，将出现频率高的基站标识确定为所述待定位终端对应的基站标识，并通过对所述待定位终端对应的基站标识相关的历史位置信息进行聚类、加权等计算，进而准确的得到待定位终端对应的基站标识以及与所述基站标识相关的常用位置信息集合，更加快速的实现基于基站的准确定位，提高基于基站的定位的速度，从而更好地满足用户的需求和体验。
