为使本发明实施例要解决的技术问题、 技术方案和优点更加清楚, 下 面将结合附图及具体实施例进行详细描述。
本发明实施例提供了一种定位方法, 用于定位中心, 所述方法如图 1 所示, 包括:
步骤 11, 当接收到请求定位第一终端的定位请求消息时, 根据预存的 终端标识与终端当前所在基站的基站信息之间的第一对应关系, 计算所述 第一终端的原始位置范围, 其中所述定位请求消息中携带所述第一终端的 第一终端标识;
步骤 12, 获取处于目标位置范围内的至少三个第二终端的第二位置信 息, 其中所述第二终端的定位精度高于所述第一终端的定位精度, 所述目 标位置范围根据所述第一终端的原始位置范围和预设的区域半径确定; 步骤 13, 根据所述第一终端标识, 获取所述第一终端测量的与所述第 二终端之间的距离的测量结果;
步骤 14, 根据所述第二位置信息和所述测量结果, 计算所述第一终端 的第一位置信息。
在本发明实施例提供的上述方法中, 利用具有更高定位精度的第二终 端, 通过测量被定位的第一终端与第二终端的距离, 通过计算, 使得定位 精度较低的第一终端提高了定位精度, 实现了本发明的目的。
优选地, 第一终端为不具备 GPS定位的终端, 第二终端为具备 GPS定 位的终端。 第一终端在有障碍物遮挡的场所, 例如室内, 只能通过基站定 位确定第一位置信息, 而通过本发明实施例提供的方法, 第一终端可以在 有障碍物遮挡的场所进行高精度定位, 提高了用户体验。 从而还可进行各 种高精度位置应用。
当然, 除了上述情况, 在其他情况下, 只要第二终端的定位精度高于 第一终端的定位精度, 使用本发明实施例提供的方法计算第一终端的第一 位置信息, 均能提高第一终端的定位精度。 下面分步骤介绍一下本发明实施例提供的上述方法。
步骤 11, 当接收到请求定位第一终端的定位请求消息时, 根据预存的 终端标识与终端当前所在基站的基站信息之间的第一对应关系, 计算所述 第一终端的原始位置范围, 其中所述定位请求消息中携带所述第一终端的 第一终端标识。
这里的定位请求消息可以是第一终端发送的, 也可以是第三方平台通 过定位业务服务器发送到所述定位中心的。 即本发明实施例不仅适用于由 终端发起的定位过程, 也适用于由定位业务服务器发起的定位过程。
在接收到定位请求消息后, 定位中心需要首先确定第一终端的原始位 置范围。 其中, 优选地, 根据预存的终端标识与终端当前所在基站的基站 信息之间的第一对应关系, 计算所述第一终端的原始位置范围包括:
根据所述第一对应关系, 确定与所述第一终端标识对应的第一基站信 息;
根据所述第一基站信息进行基站定位, 计算所述第一终端的原始位置 范围。
定位中心与预存第一对应关系的数据库连接, 当接收到定位请求消息 后, 查询所述数据库, 确定与第一终端的第一终端标识对应的第一基站信 息, 在根据该第一基站信息进行基站定位, 计算出第一终端的原始位置范 围。 这个原始位置范围是一个精确度较低的范围。
由于终端在发生位置更新时, 会发送消息到移动通信网络进行基站切 换。 因此, 在本发明实施例中, 可以在移动通信网络检测到终端发生位置 改变后, 获取终端当前所述的基站信息等发送到定位中心, 定位中心将终 端的标识信息与所在基站的基站信息更新到所述数据库中。 这样, 可以确 保数据库中始终存储着最新的终端的标识信息与所在基站的基站信息的第 一对应关系。 这里的终端既可以是第一终端, 也可以是定位精度较高的第 二终端。
对于上述形成第一对应关系的过程, 如图 2所示, 包括:
步骤 21, 终端 (包括第一终端和第二终端)通过移动通信信号接入移 动网络, 当其位置改变时, 发送消息到移动通信网络进行基站切换。
步骤 22, 移动通信网络基站系统检测到终端位置发生改变后, 将该终 端所属基站等信息发送给定位中心。
步骤 23, 定位中心收到终端位置改变消息后, 发送消息到数据库, 更 新该终端的基站信息。
在确定了第一终端的原始位置范围后, 需要执行步骤 12, 获取处于目 标位置范围内的至少三个第二终端的第二位置信息, 其中所述第二终端的 定位精度高于所述第一终端的定位精度, 所述目标位置范围根据所述第一 终端的原始位置范围和预设的区域半径确定。
获取第二位置信息时可以通过以下两种方式实现。
<方式一 >
步骤 13包括:
根据所述第一对应关系, 确定处于目标位置范围内的至少三个第二终 端的第二终端标识;
所述定位中心根据所述第二终端标识, 发送请求获取所述第二终端的 第二位置信息的位置请求消息到所述第二终端;
获取所述第二终端根据所述位置请求消息进行定位后确定的所述第二 位置信息。
在本发明实施例中, 优选地, 以第一终端的原始位置范围为圓心, 根 据预设的区域半径确定出目标区域范围。 再根据终端标识与基站信息之间 的第一对应关系, 确定出在目标区域范围内的基站下的至少三个第二终端 的第二终端标识。 终端标识为能够标识该终端的信息, 可以为国际移动用 户 i只另 ll码 ( International Mobile Subscriber Identification Number, IMSI ), 也
MSISDN )。 此时, 定位中心会请求第二终端对自身进行定位, 并将准确的 第二定位信息返回给定位中心。 由于第二终端的定位精度高于第一终端, 那么定位中心获得的第二位置信息也是较为准确的。
另外, 对于定位精度较高的第二终端, 可以直接将第二终端的第二定 位信息保存到数据库中, 形成终端标识和位置信息的第二对应关系, 这样 步骤 13就可以直接通过以下方式实现。
<方式二 >
步骤 12包括:
从预存的终端标识和终端的位置信息的第二对应关系中, 确定处于目 标位置范围内的至少三个第二终端的第二终端标识;
根据第二终端的第二终端标识和所述第二对应关系, 确定所述第二位 置信息。
在方式二中, 同样需要先确定出目标区域范围, 进一步地, 确定处于 目标区域范围内的至少三个第二终端的第二终端标识, 并根据第二对应关 系, 直接获取所述第二位置信息。
无论釆用上述何种方式获取第二位置信息后, 需要执行步骤 13, 根据 所述第一终端标识, 获取所述第一终端测量的与所述第二终端之间的距离 的测量结果。
步骤 13优选地, 包括:
根据所述第一终端标识, 发送请求测量所述第一终端与所述第二终端 之间的距离的测量请求消息到所述第一终端;
获取所述第一终端根据所述测量请求消息测量所述第一终端与所述第 二终端之间的距离的测量结果。 其中, 所述测量请求消息中需要携带所述第二终端的第二终端标识。 第一终端根据测量请求消息中携带的第二终端标识, 优选地, 通过无 线电信号测量与所述第二终端之间的距离, 获取所述测量结果。
具体地, 第一终端根据第二终端标识, 向第二终端通过无线电信号发 送请求测量距离的测量请求消息, 将此时对应的时间点记为 Tl。 这里主要 是考虑到无线电信号是具有固定的传输速率的。 第二终端在收到第一终端 发送的请求消息后, 立即通过无线电信号返回响应消息给第一终端。 第一 终端接收到第二终端返回的响应消息的时间点为 Τ2。第一终端可以根据 Τ2 与 T1的时间差, 以及无线电信号的传输速率计算出第一终端与第二终端之 间的 巨离。
第一终端测量出与所述第二终端之间的距离后, 定位中心获取该测量 结果。
再执行步骤 14, 定位中心根据所述第二位置信息和所述测量结果, 计 算所述第一终端的第一位置信息。
其中优选地, 步骤 14具体为:
根据所述第二位置信息和所述测量结果, 进行三角计算, 得到所述第 一终端的第一位置信息。
对应于上述用于定位中心的定位方法, 本发明实施例还提供了一种定 位方法, 用于第一终端, 所述方法如图 3所示, 包括:
步骤 31, 接收定位中心在接收到对所述第一终端进行定位的定位请求 消息后发送的距离测量消息, 其中所述距离测量消息请求测量所述第一终 端与第二终端之间的距离, 所述第二终端的定位精度高于所述第一终端的 定位精度;
步骤 32, 根据所述测量请求消息, 测量与所述第二终端之间的距离, 获得测量结果; 步骤 33, 将所述测量结果返回所述定位中心, 使得所述定位中心根据 所述第二位置信息和所述测量结果, 计算所述第一终端的第一位置信息。
上述的定位方法, 其中, 所述测量请求中携带所述第二终端的第二终 端标识;
根据所述测量请求消息, 测量与所述第二终端之间的距离, 获得测量 结果具体为:
根据所述测量请求消息中携带的所述第二终端标识, 通过无线电信号 测量与所述第二终端之间的距离, 获取所述测量结果。
下面具体介绍一下本发明实施例提供的定位方法的整体过程, 如图 4 所示, 包括:
步骤 41, 定位业务服务器发起定位请求, 当然还可以是第一终端 A发 起的定位请求, 如果第一终端 A发起定位, 则第一终端 A相当于定位业务 服务器, 也可以是其他的第三方平台或第三终端等接入定位业务服务器发 起定位请求;
步骤 42, 定位中心向数据库发起查询第一终端 A的第一基站信息的请 求;
步骤 43, 数据库向定位中心返回第一基站信息;
步骤 44, 定位中心根据第一基站信息, 计算出第一终端 A的原始位置 范围, 然后向数据库查询以第一终端 A的原始位置范围为圓心的预设区域 半径内的至少三个第二终端的第二终端标识, 其中第二终端 B/C/D的定位 精度高于第一终端 A;
步骤 45, 数据库返回第二终端 B/C/D的第二终端标识给定位中心; 步骤 46, 定位中心发送消息到第二终端, 要求其进行高精度定位; 步骤 47, 第二终端 B/C/D进行定位, 定位完成后将确定的第二位置信 息发给定位中心; 步骤 48, 定位中心记录每个第二终端的第二位置信息;
步骤 49, 当每收到一个第二终端的第二位置信息后, 定位中心立刻将 该第二终端的第二终端标识发送给第一终端, 要求第一终端测试其与第二 终端之间的距离;
步骤 410, 第一终端通过无线电信号发送测量请求消息到第二终端; 步骤 411, 第二终端收到第一终端的测量请求消息后, 立刻发送响应消 息给第一终端;
步骤 412,第一终端将测量的与第二终端的距离作为测量结果发送给定 位中心;
步骤 413,当定位中心收齐至少三个第二终端的第二位置信息以及其对 应的与第一终端的距离后, 进行三角计算, 计算出第一终端的第一位置信 息;
步骤 414, 定位中心将第一位置信息发送给定位业务服务器。
本发明实施例提供的定位方法, 不仅适用于由终端发起的定位过程, 也适用于由定位业务服务器发起的定位过程。 利用具有更高定位精度的第 二终端, 通过测量被定位的第一终端与第二终端的距离, 通过计算, 使得 定位精度较低的第一终端提高了定位精度; 进而可以在有障碍物遮挡的场 所进行高精度定位, 提高用户体验; 还可以进行各种高精度位置应用。
