网络定位方法、计算机设备及非易失性可读存储介质
相关申请的交叉引用
本申请要求于2017年3月14日提交中国专利局、申请号为2017101509224、发明名称为“网络定位方法、装置及计算机设备”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
本申请涉及网络技术领域，特别是涉及一种网络定位方法、计算机设备及非易失性可读存储介质。
背景技术
LBS(Location Based Service，基于位置服务)指的是通过电信或移动等运营商的无线电通讯网络，例如GSM(Global System for Mobile Communication，全球移动通信系统)网络、CDMA(Code Division Multiple Access，码多分址)网络等，或外部定位方式，例如GPS(Global Positioning System，全球定位系统)等，获取移动终端用户的位置信息，在GIS(Geographic Information System，地理信息系统)平台的支持下，为用户提供相应服务的一种增值业务。
各大网络定位提供商为了推广自身的LBS服务，通常会公布定位的SDK(Software Development Kit，软件开发工具包)，传统的LBS应用大多都集成了由第三方网络定位提供商提供的SDK。由于SDK的独立性，移动终端上的每一个LBS应用在每次进行网络定位时，都需要扫描获取无线网络信息，才能实现网络定位。当被使用的LBS应用较多时，各LBS应用集成的SDK会频繁地主动发起无线网络信息扫描，导致移动终端上的系统功耗增大，并引起无线上网延迟等问题。

如图2所示，在一个实施例中，提供一种网络定位方法，包括以下步骤：
步骤S210，接收网络定位请求。
在本申请实施例中，当用户在移动终端上使用LBS应用上的网络定位功能时，LBS应用可向移动终端的操作系统发送网络定位请求，其中，移动终端可包括手机、个人数字助理、笔记本电脑及台式计算机等，LBS应用可包括社交型LBS应用、生活服务型LBS应用及游戏型LBS应用等。每个LBS应用中可集成有由第三方网络定位提供商提供的SDK。
步骤S220，根据网络定位请求从共享文件中读取最新写入的无线网络信息。
移动终端的操作系统接收由LBS应用发送的网络定位请求，可根据网络定位请求从共享文件中读取最新写入的无线网络信息，其中，共享文件用于存储移动终端连接的无线网络信息，可将移动终端每一次连接的无线网络信 息写入共享文件中。无线网络信息可包括WiFi(Wireless Fidelity，无线保真)的热点信息和/或移动通讯中的基站信息等，其中，WiFi热点指的是WiFi的接入点(Access Point，AP)，可主要包括路由交换接入一体设备和纯接入点设备等，路由交换接入一体设备可执行接入和路由功能，纯接入设备只负责无线接入，移动终端可通过接入WiFi热点使用WiFi网络。WiFi的热点信息可包括WiFi热点的BSSID(Basic Service Set Identifier，基本服务集标识)、SSID(Service Set Identifier，服务集标识)及信号强度等，其中，BSSID用于标识一个基本服务集，一般可为WiFi热点的MAC(Media Access Control，介质访问控制)地址，SSID用于标识WiFi热点，一般可为WiFi热点的名称。基站信息可包括基站的CID(Cell Identity，基站编号)、LAC(Location Area Code，位置区域码)及信号强度等。
在一个实施例中，当将移动终端每一次连接的无线网络信息写入共享文件时，可同时在共享文件中记录写入时间，操作系统可按照写入时间的先后，从共享文件中选取写入时间最后的无线网络信息，即为最新写入的无线网络信息进行读取。
在一个实施例中，移动终端可预先规定共享文件中无线网络信息的写入位置，例如，每次都将无线网络信息写入共享文件的最末端，其中，写入共享文件的最末端指的是在共享文件原内容的末尾写入新的无线网络信息，在不同时刻写入的无线网络信息中间可用空格或空行隔开。当移动终端的操作系统接收到网络定位请求，可从共享文件中选取位于文件内容最后面的无线网络信息，即为最新写入的无线网络信息进行读取。
步骤S230，根据无线网络信息确定对应的位置信息。
移动终端的操作系统从共享文件中读取无线网络信息后，可根据无线网络信息获取对应的位置信息，其中，位置信息可包含经纬度信息等，经纬度是经度与纬度组成的一个坐标系统，称为地理坐标系统，它是一种利用三度空间的球面来定义地球上的空间的球面坐标系统，能够标示地球上的任何一个位置。位置信息可以是移动终端上预先存储的与无线网络信息对应的位置 信息，也可以是由定位服务器根据无线网络信息实时进行计算得到。
在一个实施例中，移动终端的操作系统获取与无线网络信息对应的位置信息后，可将位置信息返回给发送网络定位请求的LBS应用，LBS应用可根据位置信息进行展示，例如，在地图上展示与位置信息对应的点，或是展示与该位置信息相关的美食、银行、超市等生活服务等，但不限于此，具体的展示内容可根据LBS应用提供的具体服务功能确定。
上述网络定位方法，接收网络定位请求，根据网络定位请求从共享文件中读取最新写入的无线网络信息，根据无线网络信息确定对应的位置信息，通过共享文件实现各LBS应用之间无线网络信息的共享，无需每次进行网络定位时都主动发起无线网络信息扫描，可降低扫描无线网络信息频率，从而有效降低网络定位时的系统功耗，并减少无线上网延迟。
如图3所示，在一个实施例中，在步骤S210接收网络定位请求之前，还包括以下步骤：
步骤S302，对无线网络信息进行监听。
移动终端中可预先建立用于监听网络状态的进程，对无线网络信息进行监听，当移动终端的操作系统中的无线网络信息发生了变化，例如，移动终端连接的WiFi热点发生变化，或移动终端连接的基站发生变化等，操作系统可向监听无线网络信息的进程广播无线网络变化消息。
步骤S304，当检测到无线网络信息发生变化时，将变化后的无线网络信息写入共享文件。
当移动终端中用于监听无线网络信息的进程接收到无线网络变化消息，也即，当检测到无线网络信息发生变化时，该进程解析接收到的无线网络变化消息，可得到变化后的WiFi热点信息或基站信息等无线网络信息，并将变化后的无线网络信息写入预先创建的共享文件中，其中，共享文件除了存储移动终端连接的无线网络信息外，也可存储其它共享数据，移动终端上的不同应用可通过共享文件实现数据共享。
在本实施例中，可对无线网络信息进行监听，并将变化后的无线网络信 息写入共享文件，通过共享文件实现各LBS应用之间无线网络信息的共享，无需每次进行网络定位时都主动发起无线网络信息扫描，可降低扫描无线网络信息频率，从而有效降低网络定位时的系统功耗，并减少无线上网延迟。
如图4所示，在一个实施例中，步骤S220根据网络定位请求从共享文件中读取最新写入的无线网络信息，包括以下步骤：
步骤S402，判断共享文件中是否包含无线网络信息，若是，则执行步骤S404，若否，则执行步骤S406。
在本申请实施例中，LBS应用向移动终端的操作系统发送网络定位请求，当操作系统接收到网络定位请求时，可从共享文件中读取最新写入的无线网络信息。在一个实施例中，可每隔预设时间对共享文件中写入的数据进行清空，例如，每隔12小时、24小时等，可减少操作系统从共享文件中读取数据的时间，提高网络定位的速度。当操作系统要从共享文件中读取最新写入的无线网络信息时，可先判断共享文件中是否包含无线网络信息，若共享文件中存储有无线网络信息，则操作系统可从共享文件中读取最新写入的无线网络信息，并根据读取的无线网络信息确定对应的位置信息。
步骤S404，从共享文件中读取最新写入的无线网络信息。
步骤S406，扫描在移动终端预设范围内的无线网络设备，并获取无线网络设备的无线网络信息。
若共享文件中不包含无线网络信息，也即共享文件中的无线网络信息为空，则移动终端的操作系统可扫描在移动终端预设范围内的无线网络设备，其中，预设范围可根据移动终端实际所处区域中各无线网络设备发出的信号强度而定，若无线网络设备发出的信号强度较强，则预设范围较大，若无线网络设备发出的信号强度较弱，则预设范围较小，例如移动终端扫描300米内的无线网络设备，或扫描500米内的无线网络设备等，并不限于此。无线网络设备可以是作为WiFi热点的设备，例如路由交换接入一体设备、路由器及纯接入设备等，也可以是基站等。
在一个实施例中，移动终端对预设范围内的无线网络设备进行扫描，可 以采用主动扫描或被动扫描等方式。主动扫描指的是移动终端以主动的方式在每个信道上发出探测请求(Probe Request)帧，当预设范围内的无线网络设备接收到探测请求帧时，可发送探测应答(Probe Request)帧进行回应。若移动终端在某信道上接收到探测应答帧，则可进一步获取发出该探测应答帧的无线网络设备的无线网络信息。被动扫描指的是预设范围内的无线网络设备以定时广播的方式发送Beacon(信标)帧，移动终端会在各个信道中切换，接收Beacon帧并进行记录，从而进一步获取发送Beacon帧的无线网络设备的无线网信息。移动终端可采用被动扫描的方式对预设范围内的无线网络设备进行扫描，并获取无线网络信号，因在扫描过程中不需要传送任何信号，可以节省移动终端的功耗。
在本实施例中，当LBS应用进行网络定位时，可直接从共享文件中读取最新写入的无线网络信息，无需每次进行网络定位时都主动发起无线网络信息扫描，可降低扫描无线网络信息频率，从而有效降低网络定位时的系统功耗，并减少无线上网延迟。
如图5所示，在一个实施例中，步骤S230根据无线网络信息确定对应的位置信息，还包括：
步骤S502，获取与最新写入的无线网络信息匹配的标志位。
在一个实施例中，移动终端可通过预先建立的监听进程监听无线网络信息，当无线网络信息发送变化时，监听进程可将变化后的无线网络信息写入共享文件中，并将写入的无线网络信息的标志位置为第二标志位。无线网络信息的标志位可用于标志无线网络信息是否曾被用于计算位置信息，也即，标志位可用于表示在共享文件中是否存储有与无线网络信息对应的位置信息。在本实施例中，当无线网络信息的标志位为第一标志位时，表示该无线网络信息曾被用于计算位置信息，也即共享文件中存储有与该无线网络信息对应的位置信息；当无线网络信息的标志位为第二标志位时，表示该无线网络信息不曾被用于计算位置信息，也即共享文件中没有存储与该无线网络信息对应的位置信息。第一标志位、第二标志位可根据实际需求设定不同的表 示方式，例如第一标志位为false，第二标志位为true，或是第一标志位为0，第二标志位为1等，并不限于此。
步骤S504，判断标志位为第一标志位还是第二标志位，若是第一标志位，则执行步骤S506，若是第二标志位，则执行步骤S508。
当共享文件中包含无线网络信息时，移动终端的操作系统可从共享文件中读取最新写入的无线网络信息，同时可获取该无线网络信息的标志位，并判断标志位为第一标志位还是第二标志位。
步骤S506，从共享文件中读取与最新写入的无线网络信息对应的位置信息，并根据位置信息进行展示。
若获取的标志位为第一标志位，则说明共享文件中存储有与最新写入的无线网络信息对应的位置信息，操作系统可直接从共享文件中读取与最新写入的无线网络信息对应的位置信息，并将该位置信息返回给发起网络定位请求的LBS应用。LBS应用可根据位置信息进行展示，例如，在地图上展示与位置信息对应的点，或是展示与该位置信息相关的美食、银行、超市等生活服务等，但不限于此，具体的展示内容可根据LBS应用提供的具体服务功能确定。
步骤S508，将最新写入的无线网络信息发送至定位服务器，以使定位服务器根据无线网络信息计算对应的位置信息。
若获取的标志位为第二标志位，则说明共享文件中没有存储与最新写入的无线网络信息对应的位置信息，移动终端可将从共享文件中读取的最新写入的无线网络信息发送至定位服务器。定位服务器可根据无线网络信息中WiFi热点的BSSID、SSID或基站的CID等信息，在数据库中查询计算与接收的无线网络信息对应的位置信息。
步骤S510，接收定位服务器返回的位置信息。
步骤S512，将位置信息写入共享文件，并将标志位置为第一标志位。
移动终端接收由定位服务器返回的与无线网络信息对应的位置信息后，可将位置信息写入共享文件中，在共享文件中建立该位置信息与无线网络信 息的对应关系，并将无线网络信息的标志位置为第一标志位。
步骤S514，根据位置信息进行展示。
移动终端的操作系统可将该位置信息返回给发送网络定位请求的LBS应用，LBS应用可根据位置信息进行展示，例如，在地图上展示与位置信息对应的点，或是展示与该位置信息相关的美食、银行、超市等生活服务等，但不限于此，具体的展示内容可根据LBS应用提供的具体服务功能确定。
在本实施例中，当LBS应用进行网络定位时，除了可直接从共享文件中读取最新写入的无线网络信息外，也可从共享文件中读取对应的位置信息，无需每次进行网络定位时都主动发起无线网络信息扫描，也无需每次进行网络定位时都对定位服务器进行访问，可降低扫描无线网络信息及访问定位服务器的频率，在有效降低网络定位的系统功耗的同时，也可快速响应网络定位请求。
如图6所示，在一个实施例中，步骤S230根据无线网络信息确定对应的位置信息，包括以下步骤：
步骤S602，当共享文件中不包含无线网络信息时，将扫描获取的无线网络信息发送至定位服务器，以使定位服务器根据无线网络信息计算对应的位置信息。
当共享文件中不包含无线网络信息时，移动终端可扫描预设范围内的无线网络设备，并获取无线网络信息。在一个实施例中，移动终端扫描获取的无线网络信息可以是一份或多份，移动终端可从中选取信号强度最强的无线网络设备的无线网络信息发送至定位服务器，也可以根据获取的多份无线网络信息生成无线网络信息列表，并将无线网络信息列表发送至定位服务器，从而提高位置信息的准确度。定位服务器可根据接收的无线网络信息或无线网络信息列表，在数据库中查询计算对应的位置信息。
步骤S604，接收定位服务器返回的位置信息。
步骤S606，将位置信息及扫描获取的无线网络信息写入共享文件，并将扫描获取的无线网络信息的标志位置为第一标志位。
移动终端接收由定位服务器返回的位置信息后，可将位置信息与发送给定位服务器的无线网络信息或无线网络信息列表一起写入共享文件中，建立写入的位置信息与无线网络信息或无线网络信息列表的对应关系，并将写入的无线网络信息或无线网络信息列表的标志位置为第一标志位，当下一LBS应用发起网络定位请求时，移动终端的操作系统可直接从共享文件中读取无线网络信息及对应的位置信息。
步骤S608，根据位置信息进行展示。
移动终端的操作系统可将该位置信息返回给发送网络定位请求的LBS应用，LBS应用可根据位置信息进行展示，例如，在地图上展示与位置信息对应的点，或是展示与该位置信息相关的美食、银行、超市等生活服务等，但不限于此，具体的展示内容可根据LBS应用提供的具体服务功能确定。
可以理解地，将无线网络信息写入共享文件中，除了实现各LBS应用间无线网络信息的共享外，其它非LBS应用当需要获取无线网络信息时，也可直接从共享文件中读取，并不仅限于LBS应用及网络定位功能。
在本实施例中，可将扫描获取的无线网络信息及由定位服务器查询计算的位置信息写入共享文件中，实现各LBS应用间无线网络信息与位置信息的共享，可降低扫描无线网络信息及访问定位服务器的频率，在有效降低网络定位时的系统功耗的同时，也可快速响应网络定位请求。
