附图说明
图1是示出根据本发明的示例性实施例的定位检测方法的流程图；
图2是示出根据本发明的示例性实施例的定位检测的装置结构框图。
具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本发明进行详细描述。
图1示出了本发明一种定位检测方法的优选实施例的流程图。图2示出的一种定位检测装置可用于实现图1中所述的方法。
参照图1，在110中，所述装置获取任意一条定位请求的定位信号。
其中，该定位请求可以线上的，也可以是线下的，对此本发明没有限制。
在120中，所述装置通过已有的定位服务***获得与该定位请求的定位信号对应的位置信息。
在130中，所述装置从预置的不良定位结果(即Badcase)数据库中获得与该定位请求的定位信号对应的不良定位结果(即Badcase)的位置信息，所述不良定位结果(即Badcase)数据库用于存储定位请求的定位信号及定位请求的定位信号对应的不良定位结果(即Badcase)的位置信息。
在140中，所述装置确定获得的位置信息与获得的不良定位结果(即Badcase)的位置信息是否相近。
在150中，如果获得的位置信息与获得的不良定位结果(即Badcase)的位置信息相近，则所述装置确定获得的位置信息为不良定位结果(即Badcase)。
由于用户每天都会不断地产生新的定位请求，为了使得不良定位结果(即Badcase)数据库能够及时、准确地反映出定位服务***中新增的不良定位结果(即Badcase)，需要对用户新增的日志数据进行不良定位结果(即Badcase)挖掘，根据本发明的一个可选实施例，在图1所示的实施例中，所述方法还包括：所述装置在从预置的不良定位结果(即Badcase)数据库中获得与该定位请求的定位信号对应的不良定位结果(即Badcase)的位置信息以前，更新不良定位结果(即Badcase)数据库。
根据本发明的一个示例性实施例，所述装置更新不良定位结果(即Badcase)数据库的具体步骤为：所述装置从定位服务***生成的定位日志中挖掘不良定位结果(即Badcase)；根据挖掘的不良定位结果(即 Badcase)更新不良定位结果(即Badcase)数据库。具体实施，所述装置可在线下通过hadoop(即一种分布式软件框架)平台对已有的定位服务***每日生成的定位日志进行不良定位结果(即Badcase)挖掘和汇总。
其中，所述装置从定位服务***生成的定位日志中挖掘不良定位结果(即Badcase)的具体步骤为：所述装置从定位服务***生成的定位日志中获取任意一条定位请求的定位信号及定位服务***根据该定位请求的定位信号计算的位置信息；确定计算的位置与该定位请求的实际位置之间的距离；如果确定的距离大于给定阈值，则确定计算的位置信息为不良定位结果(即Badcase)。
其中，该定位请求的实际位置可以是已知的，也可以通过该手机定位请求携带的GPS(Global Positioning System，即全球定位***)信息获得，对此本发明不作限制。
另外，还需要指出的是，上述不良定位结果(即Badcase)数据库的更新方式仅仅只是示例性的，本发明并不受限与此，只要有助于获得最新的不良定位结果(即Badcase)数据，则均可应用于本发明。
根据本发明的手机定位请求携带有GPS信息的示例性实施例，用户如果在手机上开启了GPS定位服务，则所述装置获得的定位请求中不仅包含有定位请求的定位信号，而且还包含有定位请求的GPS信息，即该定位请求的实际位置(gps_x,gps_y)；所述装置通过已有的定位服务***获得与该定位请求的定位信息对应的位置信息(resx,resy)，然后计算获得的位置(resx,resy)与该定位请求的实际位置(gps_x,gps_y)之间的距离，如果计算的距离大于给定阈值，则确定计算的位置信息为不良定位结果(即Badcase)，也就是说，通过已有的定位服务***获得的位置信息(resx, resy)偏离了该定位请求的实际位置(gps_x,gps_y)，所述装置可将其作为一条不良定位结果(即Badcase)存储至不良定位结果(即Badcase)数据库中，具体实施时，所述装置可以将获得的整个定位请求及通过定位服务***获得的位置信息按照对应关系存储至不良定位结果(即Badcase)数据库中，具体的数据格式如下：
Request_context,resx,resy
其中，Request_context为手机定位请求内容，该请求内容可以是基站定位信息，也可以是Wi-Fi定位信息，还可以是两者的组合，对此本发明也不作限制。
为了给修复定位服务***提供合理可靠的依据，根据本发明的另一可选实施例，在图1所示的实施例中，还包括：所述装置确定造成获得的位置信息为不良定位结果(即Badcase)的原因。
具体地，根据本发明的该定位请求的定位信号为基站定位信号的示例性实施例，所述装置确定造成获得的位置信息为不良定位结果(即Badcase)的原因的具体步骤为：所述装置从定位服务***的基站信息数据库中获得与该定位请求的基站定位信号对应的基站位置信息；确定获得的基站位置与该定位请求的实际位置之间的距离；如果确定的距离小于第一预设距离，则确定获得的基站位置相对于该定位请求的实际位置没有发生偏离，并且确定造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***根据获得的基站位置信息确定与该定位请求的基站定位信号对应的基站位置信息的方式出现了错误；如果确定的距离不小于第一预设距离，则确定获得的基站位置相对于该定位请求的实际位置发生了偏离，并且确定造成获得的位置信息为不良定位结果 (即Badcase)的原因是获得的基站位置相对于该定位请求的实际位置发生了偏离。
更为具体地，根据本发明的该定位请求的定位信号为基站定位信号的示例性实施例，所述装置确定造成获得的位置信息为不良定位结果(即Badcase)的原因是获得的基站位置相对于该定位请求的实际位置发生了偏离的具体步骤为：所述装置从定位服务***的基站信息数据库中获得与该定位请求的基站定位信号对应的基站位置信息的置信范围；如果该定位请求的实际位置在获得的置信范围内，则确定获得的置信范围的数据是正确的，并且确定造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***的基站信息数据库创建与该定位请求的基站定位信号对应的基站位置信息的方式出现了错误；如果该定位请求的实际位置不在获得的置信范围内，则确定获得的置信范围的数据不是正确的，并且确定造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***的基站信息数据库的所有位置数据都是错误的。
具体地，根据本发明的该定位请求的定位信号为Wi-Fi定位信号的示例性实施例，所述装置确定造成获得的位置信息为不良定位结果(即Badcase)的原因的具体步骤为：所述装置从定位服务***的Wi-Fi热点信息数据库中获得与该定位请求的Wi-Fi定位信号对应的Wi-Fi热点位置信息；确定获得的Wi-Fi热点位置与该定位请求的实际位置之间的距离；如果确定的距离小于第二预设距离，则确定获得的Wi-Fi热点位置相对于该定位请求的实际位置没有发生偏离，并且确定造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***根据获得的Wi-Fi热点位置信息确定与该定位请求的Wi-Fi定位信号对应的Wi-Fi热点位置信 息的方式出现了错误；如果确定的距离不小于第二预设距离，则确定获得的Wi-Fi热点位置相对于该定位请求的实际位置发生了偏离，并且确定造成获得的位置信息为不良定位结果(即Badcase)的原因是获得的Wi-Fi热点位置相对于该定位请求的实际位置发生了偏离。
更为具体地，根据本发明的该定位请求的定位信号为Wi-Fi定位信号的示例性实施例，所述装置确定造成获得的位置信息为不良定位结果(即Badcase)的原因是获得的Wi-Fi热点位置相对于该定位请求的实际位置发生了偏离的具体步骤为：所述装置从定位服务***的Wi-Fi热点信息数据库中获得与该定位请求的Wi-Fi定位信号对应的Wi-Fi热点位置信息的置信范围；如果该定位请求的实际位置在获得的置信范围内，则确定获得的置信范围的数据是正确的，并且确定造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***的Wi-Fi热点信息数据库创建与该定位请求的Wi-Fi定位信号对应的Wi-Fi热点位置信息的方式出现了错误；如果该定位请求的实际位置不在获得的置信范围内，则确定获得的置信范围的数据不是正确的，并且确定造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***的Wi-Fi热点信息数据库的所有位置数据都是错误的。
需要指出的是，所述装置可以单独实施上述两个示例性实施例中任意一个，也可以将上述两个示例性实施组合在一起实施。
以下以Wi-Fi定位信息为例，对本发明的具体实施过程作进一步的说明：
其中，Wi-Fi定位信息的具体数据内容如下：
mac1,rssi1|mac2；rssi2|……
上述数据表示的是该定位请求中周围各个热点的mac地址及其对应的信号强度rssi，这说明Wi-Fi定位包含有mac和rssi两个字段信息。
当该定位请求的定位信息为Wi-Fi定位信息时，所述装置通过已有的***定位服务***获得与该定位请求的Wi-Fi定位信息对应的Wi-Fi热点位置信息(wifix,wifiy)；然后确定获得的Wi-Fi热点位置信息(wifix,wifiy)与该定位请求的实际位置(gps_x,gps_y)之间的距离；如果确定的距离不大或者很小，则说明获得的Wi-Fi热点位置相对于该定位请求的实际位置没有发生偏离，造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***根据获得的Wi-Fi热点位置信息确定与该定位请求的Wi-Fi定位信号对应的Wi-Fi热点位置信息的方式有问题；如果确定的距离很大，则说明获得的Wi-Fi热点位置相对于该定位请求的实际位置发生了偏离，造成获得的位置信息为不良定位结果(即Badcase)的原因是获得的Wi-Fi热点位置相对于该定位请求的实际位置发生了偏离。
为进一步确定出上述偏离对已有的定位服务***造成的影响，所述装置可继续从定位服务***的Wi-Fi热点信息数据库中获得与该定位请求的Wi-Fi定位信号对应的Wi-Fi热点位置信息的置信范围(wifix,wifiy,wifi_radius)；如果该定位请求的实际位置(gps_x,gps_y)在获得的置信范围内，则说明造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***的Wi-Fi热点信息数据库创建与该定位请求的Wi-Fi定位信号对应的Wi-Fi热点位置信息的方式出现了问题；如果该定位请求的实际位置(gps_x,gps_y)不在获得的置信范围内，则说明造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***的Wi-Fi热点信息数据库的整体数据都是错误的。
如果走基站定位策略的请求中会带有基站信息(cellID)，走wifi定位策略的请求中会带有wifi信息(mac,rssi)，如果请求中同时带有基站信息和wifi信息，定位服务通常走的是整合两个信息的wifi定位策略。
图2示出了本发明一种定位检测装置的优选实施例结构框图。
参照图2，所述装置至少包括定位请求获取单元201、原有定位服务单元202、不良定位单元203、结果对比单元204以及不良定位确定单元205。
其中，定位请求获取单元201，用于获取任意一条定位请求的定位信号。
原有定位服务单元202，用于通过已有的定位服务***获得与该定位请求的定位信号对应的位置信息。
不良定位单元203，用于从预置的不良定位结果(即Badcase)数据库中获得与该定位请求的定位信号对应的不良定位结果(即Badcase)的位置信息，所述不良定位结果(即Badcase)数据库用于存储定位请求的定位信号及定位请求的定位信号对应的不良定位结果(即Badcase)的位置信息。
结果对比单元204，用于确定获得的位置信息与获得的不良定位结果(即Badcase)的位置信息是否相近。
不良定位确定单元205，用于如果获得的位置信息与获得的不良定位结果(即Badcase)的位置信息相近，则确定获得的位置信息为不良定位结果(即Badcase)。
由于用户每天都会不断地产生新的定位请求，为了使得不良定位结果(即Badcase)数据库能够及时、准确地反映出定位服务***中新增的不良定位结果(即Badcase)，还需要对用户新增的日志数据进行不良定 位结果(即Badcase)挖掘，根据本发明的一个可选实施例，在图2所示的实施例中，还包括：不良定位更新单元(图中未示出)，用于在从预置的不良定位结果(即Badcase)数据库中获得与该定位请求的定位信号对应的不良定位结果(即Badcase)的位置信息之前，更新不良定位结果(即Badcase)数据库。
根据本发明的一个示例性实施例，所述不良定位更新单元包括：不良定位挖掘子单元(图中未示出)，用于从定位服务***生成的定位日志中挖掘不良定位结果(即Badcase)；不良定位更新子单元(图中未示出)，用于根据挖掘的不良定位结果(即Badcase)更新不良定位结果(即Badcase)数据库。
其中，该定位请求的实际位置可以是已知的，也可以通过该手机定位请求携带的GPS信息获得，对此本发明不作限制。
另外，还需要指出的是，上述不良定位结果(即Badcase)数据库的更新方式仅仅只是示例性的，本发明并不受限与此，只要有助于获得最新的不良定位结果(即Badcase)数据，则均可应用于本发明。
为了给修复定位服务***提供合理可靠的依据，根据本发明的另一可选实施例，在图2所示的实施例中，还包括：不良定位分析单元(图中未示出)，用于确定造成获得的位置信息为不良定位结果(即Badcase)的原因。

更为具体地，根据本发明的该定位请求的定位信号为基站定位信号的示例性实施例，所述第二分析子单元从定位服务***的基站信息数据库中获得与该定位请求的基站定位信号对应的基站位置信息的置信范围；如果该定位请求的实际位置在获得的置信范围内，则确定获得的置信范围的数据是正确的，并且确定造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***的基站信息数据库创建与该定位请求的基站定位信号对应的基站位置信息的方式出现了错误；如果该定位请求的实际位置不在获得的置信范围内，则确定获得的置信范围的数据不是正确的，并且确定造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***的基站信息数据库的所有位置数据都是错误的。
具体地，根据本发明的该定位请求的定位信号为Wi-Fi定位信号的示例性实施例，所述不良定位分析单元包括：Wi-Fi信息获取子单元，用于从定位服务***的Wi-Fi热点信息数据库中获得与该定位请求的Wi-Fi定位信号对应的Wi-Fi热点位置信息；第二距离确定子单元，用于确定获得 的Wi-Fi热点位置与该定位请求的实际位置之间的距离；第三分析子单元，用于如果确定的距离小于第二预设距离，则确定获得的Wi-Fi热点位置相对于该定位请求的实际位置没有发生偏离，并且确定造成获得的位置信息为不良定位结果(即Badcase)的原因是定位服务***根据获得的Wi-Fi热点位置信息确定与该定位请求的Wi-Fi定位信号对应的Wi-Fi热点位置信息的方式出现了错误；第四分析子单元，用于如果确定的距离不小于第二预设距离，则确定获得的Wi-Fi热点位置相对于该定位请求的实际位置发生了偏离，并且确定造成获得的位置信息为不良定位结果(即Badcase)的原因是获得的Wi-Fi热点位置相对于该定位请求的实际位置发生了偏离。
