Description

移动终端定位方法、 装置及移动终端
技术领域 本发明涉及移动通信技术领域, 尤其涉及一种无线保真 (Wireless Fidelity, 简称 为 WiFi) 定位和移动蜂窝网络小区标识 (CelllD) 定位相结合的移动终端定位方法、 装置及移动终端。 背景技术 随着移动通信技术的迅速发展, 基于位置的服务(Location Based Service, 简称为 LBS) 越来越受到人们的关注, LBS在智能交通、 紧急救援、 工作流管理、 财产监控 等方面的应用已相当普遍, 而提供这些 LBS服务的基础就是移动定位技术。 目前,移动定位技术可以分为基于卫星的定位技术、基于 WiFi的定位技术和基于 移动蜂窝网络 (Cellid) 的定位技术。 其中, 基于卫星的定位技术主要有全球定位系统(Global Position System, 简称为 GPS)、 格洛纳斯导航系统 (GLONASS, 俄罗斯的卫星导航系统) 以及北斗等。 GPS 定位的基本原理是把高速运动的卫星瞬时所在的位置作为已知的计算数据, 采用空间 距离后方交会的方法来计算待测点的位置,它要求 GPS接收机在某一时刻接收 4颗及 以上的 GPS卫星信号。 GPS定位技术具有定位精度高的特点, 但是它只适合在室外开 阔环境中进行定位, 在室内及高楼林立的城市环境中由于卫星信号受到遮挡而很难实 现定位。
WiFi定位的原理是: 由于 WiFi热点位置比较固定, 一般很少变动, 如果能事先 知道各个 WiFi热点的经纬度坐标, 就可以根据移动终端搜索到的 WiFi热点信息查询 该热点对应的经纬度坐标, 进而实现定位。 WiFi定位具有定位速度快, 定位精度高, 非常适合在人口、 楼群越密集的地方进行定位的特点。 但是, 其缺点在于: 有时候会 有人为的挪动 WiFi位置的情况(比如搬家把无线路由器从一个地方挪到另一个地方), 此时, 若单纯依靠 WiFi定位就可能造成定位错误的情况。 CelllD定位原理和 WiFi定位原理相似,定位服务器会事先存储每个基站的经纬度 信息, 移动终端在向定位服务器请求位置信息时, 会把当前搜索到的基站信息发送给 定位服务器,定位服务器根据收到的基站信息就可以查询到该基站对应的经纬度坐标, 并把该经纬度坐标返回给移动终端作为移动终端当前所在的位置, 这样移动终端就实 现了定位。 CelllD虽然定位速度快, 但是其定位精度很低, 很难满足高精度定位的需 求。 通常对于用户而言, 首先考虑的是定位位置的正确性, 其次是定位的精度, 如果 在室外开阔地带, GPS自然是用户的首选定位方式, 但是如果在室内或高楼林立的不 适合 GPS定位的环境,则要考虑使用 WiFi或 CelllD进行定位。而单独使用 WiFi定位, 如果 WiFi位置被人为挪动(比如搬家)就有可能出现定位错误的情况, 这对用户来说 是无法接受的; 如果单独使用 CelllD定位, 由于基站位置不会轻易的被挪动, 因此定 位位置不会有大的错误, 但是定位精度却较低。 发明内容 本发明实施例提供了一种移动终端定位方法、 装置及移动终端, 旨在提高移动终 端定位的准确性和定位精度。 为了达到上述目的, 本发明实施例提出了一种移动终端定位方法, 包括: 接收应 用服务器发起的定位请求; 根据所述定位请求分别发起 WiFi定位流程和 CelllD定位 流程, 并分别获取 WiFi定位结果和 CelllD定位结果; 采用预定规则对所述 WiFi定位 结果和 CelllD定位结果进行处理, 获取最终定位结果。 优选地, 所述根据定位请求发起 WiFi定位流程获取 WiFi定位结果的步骤包括: WiFi定位模块向 WiFi定位服务器发送当前探测到的 WiFi热点信息并请求定位结果; WiFi定位模块接收所述 WiFi定位服务器返回的 WiFi定位结果。 优选地,所述根据定位请求发起 CelllD定位流程获取 CelllD定位结果的步骤包括: CelllD 定位模块向 CelllD 定位服务器发送当前探测到的移动网络信息并请求定位结 果; CelllD定位模块接收所述 CelllD定位服务器返回的 CelllD定位结果。 优选地, 所述采用预定规则对所述 WiFi定位结果和 CelllD定位结果进行处理, 获取最终定位结果的步骤包括: 将所述 WiFi定位结果和 CelllD定位结果进行比较; 若所述 WiFi定位结果与 CelllD定位结果之间的差值小于预设阈值, 则以所述 WiFi定 位结果作为最终定位结果; 否则, 以所述 CelllD定位结果作为最终定位结果。 优选地, 该方法还包括: 将获取的所述最终定位结果返回给所述应用服务器。 本发明实施例还提出了一种移动终端定位装置,包括:接收模块、 WiFi定位模块、 CelllD定位模块及数据处理模块, 其中: 所述接收模块设置为接收应用服务器发起的 定位请求; 所述 WiFi 定位模块设置为根据所述定位请求发起 WiFi 定位流程, 获取 WiFi定位结果, 并将所述 WiFi定位结果发送给所述数据处理模块; 所述 CelllD定位 模块设置为根据所述定位请求发起 CelllD定位流程, 获取 CelllD定位结果, 并将所述 CelllD定位结果发送给所述数据处理模块; 所述数据处理模块设置为采用预定规则对 所述 WiFi定位结果和 CelllD定位结果进行处理, 获取最终定位结果。 优选地,所述 WiFi定位模块还设置为向 WiFi定位服务器发送当前探测到的 WiFi 热点信息并请求定位结果; 接收所述 WiFi定位服务器返回的 WiFi定位结果。 优选地,所述 CelllD定位模块还设置为向 CelllD定位服务器发送当前探测到的移 动网络信息并请求定位结果; 接收所述 CelllD定位服务器返回的 CelllD定位结果。 优选地, 所述数据处理模块还设置为将所述 WiFi定位结果和 CelllD定位结果进 行比较; 若所述 WiFi定位结果与 CelllD定位结果之间的差值小于预设阈值, 则以所 述 WiFi定位结果作为最终定位结果; 否则, 以所述 CelllD定位结果作为最终定位结 果。 优选地,所述数据处理模块还设置为将所述最终定位结果返回给所述应用服务器。 本发明实施例还提出了一种移动终端, 包括如上所述的装置。 本发明实施例提出的移动终端定位方法、 装置及移动终端, 在需要定位时, 根据 定位请求分别发起 WiFi定位流程和 CelllD定位流程,获取 WiFi定位结果和 CelllD定 位结果, 然后对该 WiFi定位结果和 CelllD定位结果采用一定的规则进行处理, 得到 最终定位结果, 由于综合考虑了 WiFi定位结果和 CelllD定位结果, 从而解决了单独 依靠 WiFi定位在 WiFi位置变动后导致定位错误、单独依靠 CelllD定位存在的定位精 度低的问题, 提高了移动终端定位的准确性和定位精度。 附图说明 图 1是本发明实施例的移动终端定位方法一的流程示意图; 图 2 是本发明实施例的移动终端定位方法一的优选流程示意图; 图 3是本发明实施例的移动终端定位装置一的结构示意图。 为了使本发明的技术方案更加清楚、 明了, 下面将结合附图作进一步详述。 具体实施方式 本发明实施例的方案是: 在需要定位时,根据定位请求分别发起 WiFi定位流程和 CelllD定位流程, 获取 WiFi定位结果和 CelllD定位结果, 然后对该 WiFi定位结果和 CelllD定位结果采用一定的规则进行处理, 得到最终定位结果, 以解决单独依靠 WiFi 定位在 WiFi位置变动后导致定位错误、 单独依靠 CelllD定位存在的定位精度低的问 题, 提高移动终端定位的准确性和定位精度。 本发明实施例中移动终端具有 WiFi定位和 CelllD定位功能。 如图 1所示, 本发明实施例提出了一种移动终端定位方法, 包括: 步骤 S101, 接收应用服务器发起的定位请求; 本实施例方法运行环境涉及移动终端、对移动终端进行定位的 WiFi定位服务器和

WiFi定位模块 201探测移动终端周围的 WiFi热点信息(这里包含 WiFi热点的全 球唯一的 MAC地址), 发起 WiFi定位流程, 将当前探测到的 WiFi热点信息发送给 WiFi定位服务器, 并请求定位结果。
WiFi定位服务器根据收到的 WiFi热点信息查询该 WiFi热点对应的经纬度坐标, 并把该对应的经纬度坐标返回给 WiFi定位模块 201 作为移动终端当前所在的位置, WiFi定位模块 201接收到 WiFi定位服务器返回的 WiFi定位结果后, 将此 WiFi定位 结果发送给数据处理模块 203进行处理。
CelllD定位流程包括: CelllD定位模块 202探测移动终端周围的移动网络信号, 发起 CelllD定位流程, 将当前探测到的移动网络信息 (这里包含探测到的基站的 ID号) 发送给 CelllD定位 服务器并请求定位结果。
CelllD定位服务器根据收到的基站信息查询到该基站对应的经纬度坐标, 并把该 经纬度坐标返回给 CelllD定位模块 202作为移动终端当前所在的位置。
CelllD定位模块 202接收到 CelllD定位服务器返回的 CelllD定位结果后,把 CelllD 定位结果发送给数据处理模块 203进行处理。 数据处理模块 203对 WiFi定位结果和 CelllD定位结果进行处理, 以决定最终的 定位结果。 处理规则如下: 如果 WiFi定位结果和 CelllD定位结果相差小于预设阈值比如 2
KM (该值由 CelllD的定位精度确定, 由于 CelllD的定位精度一般是 1~2KM, 所以这 里可以取最大误差 2KM), 则认为 WiFi定位有效, 由于 WiFi定位精度更高, 此时使 用 WiFi定位结果作为最终的定位结果; 否则认为 WiFi定位结果无效 (这种情况下一 般是 WiFi位置变动导致), 使用 CelllD定位结果作为最终的定位结果。 之后, 数据处理模块 203把最终的定位结果返回给应用服务器。 本实施例处理流程如图 2所示。 本实施例通过上述方案, 综合考虑了 WiFi定位结果和 CelllD定位结果, 从而解 决了单独依靠 WiFi定位在 WiFi位置变动后导致定位错误、单独依靠 CelllD定位存在 的定位精度低的问题, 提高了移动终端定位的准确性和定位精度。 此外, 本实施例还提出了一种移动终端, 该移动终端包括上述实施例所述的移动 终端定位装置, 在此不再赘述。 本发明实施例移动终端定位方法、 装置及移动终端, 在需要定位时, 根据定位请 求分别发起 WiFi定位流程和 CelllD定位流程,获取 WiFi定位结果和 CelllD定位结果, 然后对该 WiFi定位结果和 CelllD定位结果采用一定的规则进行处理, 得到最终定位 结果, 由于综合考虑了 WiFi定位结果和 CelllD定位结果, 从而解决了单独依靠 WiFi 定位在 WiFi位置变动后导致定位错误、 单独依靠 CelllD定位存在的定位精度低的问 题, 提高了移动终端定位的准确性和定位精度。 工业实用性 本发明实施例在需要定位时同时发起 WiFi定位流程和 CelllD定位流程, 并同时 考虑了两种定位流程的结果, 提供了一种移动终端定位方法、 装置及移动终端, 从而 提高了移动终端定位的准确性和精度。 该方案是将两种定位流程的结合, 只需要在将 用于两种定位流程的模块结合使用即可, 不需要投入过多的新模块的研发工作, 具有 广阔的使用前景。 以上所述仅为本发明的优选实施例, 并非因此限制本发明的专利范围, 凡是利用 本发明说明书及附图内容所作的等效结构或流程变换, 或直接或间接运用在其它相关 的技术领域, 均同理包括在本发明的专利保护范围内。
