Description

一种信息推荐方法及装置 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种信息推荐方法及装置。
背景技术
目前，手机等终端可以通过采集用户在终端上的行为数据分析出用户的行为偏好，进而在各种应用场景下为用户提供一些智能的提醒事件，例如，根据用户的运动习惯对用户进行健康管理，根据接收到的乘车信息为用户添加备忘提醒，根据用户的位置为用户提供出行路线等。
然而，当用户位于密集的建筑物或者地铁站等全球定位系统(Global Positioning System，GPS)信号较弱的位置时，终端无法准确的对用户所处的位置进行定位，此时，终端无法用户提供准确的出行信息，甚至发生路线规划失败等无法响应的现象。
发明内容
本申请的实施例提供一种信息推荐方法及装置，可以在GPS信号较弱时提高终端的定位精度，从而为用户提供较为准确的出行信息。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，本申请的实施例提供一种信息推荐方法，包括：终端检测预设的地铁公共Wi-Fi网络的信号强度，得到T(T＞0)时间内该地铁公共Wi-Fi网络的信号强度变化情况；当该地铁公共Wi-Fi网络的信号强度变化情况满足由强变弱的预设规律时，终端可向用户提示与第一地铁站(即该地铁公共Wi-Fi网络所在的地铁站)相关联的出行信息。
这样一来，在GPS信号较弱的地铁站中，终端仍然可以根据其所处位置处Wi-Fi信号的强度变化对用户进行定位，并识别用户在该地铁站的出行意图，当用户具有出行意图时，终端可为用户推荐与该地铁站相关的出行信息，从而在GPS信号较弱时提高终端的定位精度，并且为用户提供与其出行意图匹配的较为准确的出行信息。还可以降低因开启GPS定位功能而增加的手机耗电量。
在一种可能的设计方法中，终端内存储有第一地铁站周边的小区ID名单；那么，当该地铁公共Wi-Fi网络的信号强度变化情况满足由强变弱的预设规律时，该方法还包括：终端获取终端当前的小区ID；终端确定终端当前的小区ID位于第一地铁站周边的小区ID名单中。
在一种可能的设计方法中，当该地铁公共Wi-Fi网络的信号强度变化情况满足由强变弱的预设规律时，该方法还包括：终端获取用户的运动状态信息；终端根据该运动状态信息确定用户的运动状态为步行态，或该用户的运动状态已由乘车态转换为步行态。
在一种可能的设计方法中，当该地铁公共Wi-Fi网络的信号强度变化情 况满足由强变弱的预设规律时，该方法还包括：终端通过查询NFC刷卡事件的记录信息，确定在预设时间内终端执行了NFC刷卡事件。
在一种可能的设计方法中，当该地铁公共Wi-Fi网络的信号强度变化情况满足由强变弱的预设规律时，该方法还包括：终端通过麦克风获取当前的环境音；终端根据获取到的环境音确定终端位于公共场所。
也就是说，终端可以通过上述辅助条件进一步确认用户离开地铁站的出行意图，避免因为目标WiFi网络的WiFi信号不稳定而导致终端错误确认用户出行意图的现象，从而提高终端确定用户出行意图时的准确性，以便后续为用户提供更加准确的出行信息。
在一种可能的设计方法中，该地铁公共Wi-Fi网络的信号强度变化情况满足由强变弱的预设规律，包括：该地铁公共Wi-Fi的信号强度降低至预设的信号强度阈值以下，和/或，该地铁公共Wi-Fi的信号的衰减速率大于预设的速率阈值。
在一种可能的设计方法中，该出行信息包括：以第一地铁站为出发地的交通工具信息，和/或，从第一地铁站到第二位置的路线信息；其中，该交通工具信息包括第一地铁站周边目标交通工具的数量信息、位置信息、预约信息以及实时公交信息中的至少一项。
在一种可能的设计方法中，在终端向用户提示与第一地铁站相关联的出行信息之前，还包括：终端在终端的下拉菜单、负一屏菜单或锁屏界面中显示该出行信息的提示信息，该提示信息用于提示用户查看该出行信息，使得用户通过提示信息可以及时查看终端为其推荐的出行信息，以提高出行效率
第二方面，本申请的实施例提供一种信息推荐方法，包括：终端检测目标Wi-Fi网络的信号强度，从而得到T(T＞0)时间内该目标Wi-Fi网络的信号变化情况；当该目标Wi-Fi网络的信号强度变化情况满足由强变弱的预设规律时，终端向用户提示与第一位置相关联的出行信息，第一位置为该目标Wi-Fi网络覆盖的区域。
这样一来，在GPS信号较弱的位置，终端仍然可以根据其所处位置处Wi-Fi信号的强度变化对用户进行定位，并识别用户在该位置处的出行意图，当用户具有出行意图时，终端可将该位置处作为出发地为用户推荐相关的出行信息，从而在GPS信号较弱时提高终端的定位精度，并且为用户提供与其出行意图匹配的较为准确的出行信息。还可以降低因开启GPS定位功能而增加的手机耗电量。
在一种可能的设计方法中，在终端向用户提示与当前位置相关联的出行信息之前，还包括：终端获取场景描述数据，该场景描述数据用于指示终端所处的应用场景；终端确定该场景描述数据满足预设的辅助条件，该辅助条件用于指示该用户准备离开第一位置。
例如，当该场景描述数据包括终端当前的小区ID时，该辅助条件包括终端当前的小区ID为预设的目标小区ID之一，该目标小区ID为第一位置周边的小区ID；当该场景描述数据包括该用户的运动状态时，该辅助条件包括该 用户的运动状态为步行态，或该用户的运动状态由乘车态转换为步行态；当该场景描述数据包括终端执行的NFC刷卡事件时，该辅助条件包括终端执行的NFC刷卡事件发生在预设时间内；当该场景描述数据包括终端的环境信息时，该辅助条件包括该环境信息用于指示终端位于公共场所。
也就是说，终端可以通过上述辅助条件进一步确认用户离开第一位置的出行意图，避免因为目标WiFi网络的WiFi信号不稳定而导致终端错误确认用户出行意图的现象，从而提高终端确定用户出行意图时的准确性，以便后续为用户提供更加准确的出行信息。
在一种可能的设计方法中，终端内预先存储有该目标Wi-Fi网络的描述信息，其中，该目标Wi-Fi网络的描述信息为用户预先输入和/或终端预先下载的。
例如，该目标Wi-Fi网络的描述信息为该目标Wi-Fi网络的服务集标识SSID；此时，在终端检测目标Wi-Fi网络的信号强度之前，还包括：终端检测上述第一位置处覆盖的N(N＞0)个Wi-Fi网络；进而，终端从这N个Wi-Fi网络中选择与预先存储的SSID相同的Wi-Fi网络作为目标Wi-Fi网络。这样，通过终端的Wi-Fi装置便可较为准确的对用户进行定位，同时降低手机的耗电量。
在一种可能的设计方法中，该目标Wi-Fi网络的信号强度变化情况满足由强变弱的预设规律，包括：该目标Wi-Fi的信号强度降低至预设的信号强度阈值以下，和/或，该目标Wi-Fi的信号的衰减速率大于预设的速率阈值。
在一种可能的设计方法中，该出行信息包括以第一位置为出发地的交通工具信息，该交通工具信息中包括：目标交通工具的数量信息、位置信息、预约信息，以及距离第一位置最近目标公交站的实时公交信息中的至少一个。

具体实施方式
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
本申请实施例提供一种信息推荐方法，可应用于图1所示的无线保真(Wireless Fidelity，Wi-Fi)网络架构中。
在一种可能的设计方法中，如图1中的(a)所示，上述Wi-Fi网络中包括网络侧的服务器11，与服务器11连接的无线局域网的接入点(Access Point，AP)12，以及与接入点12连接的至少一个站点(Station，STA)13。
其中，接入点12是一个无线网络的创建者，可以为站点13提供Wi-Fi信号源，同时，接入点12可以与网络侧的服务器11进行通信，以使得站点13可以通过无线的方式与网络侧的服务器11交互。例如，一般家庭或者办公室中使用的路由器或Wi-Fi信号发射端均可以作为上述接入点11。而每一个连接到上述Wi-Fi网络中的终端(例如，手机、笔记本电脑、PDA及其它可以联网的用户设备)都可称为站点13。
在一种可能的设计方法中，如图1中的(b)所示，当某个区域的面积较大时，一个接入点12往往不能覆盖全部的区域，例如，大型商场或者地铁站等公共场所，此时，可以利用接入点12进行无线中继的方法实现同一WiFi网络的大面积覆盖。在这种Wi-Fi网络中包括多个接入点12，例如，多个无线路由器，每一个无线路由器对各个站点13均显示同一WiFi网络的名称。
以手机100作为上述站点13，无线路由器200作为上述接入点12举例，当手机100开启无线局域网功能后，如图2所示，手机可以获取到无线路由器200定期发送的探测请求(Probe Request)帧，该Probe Request中携带有无线局域网的服务集标识(Service Set Identifier，SSID)，即Wi-Fi网络的名称。这样，手机100可以探测到无线路由器200提供的无线局域网的SSID(如Xyzd)和手机100在其所在区域内检测到的其他无线局域网的SSID。
此时，如果用户打开手机100中的无线局域网的设置界面，可显示如图3所示的无线局域网界面201。如图3所示，该无线局域网界面201可以包括：地铁公共Wi-Fi 203、Xyzd 204(即无线路由器200提供的Wi-Fi网络的SSID)和Zhangsan 205等多个SSID。
可选的，在终端探测到当前覆盖的至少一个无线局域网的SSID后，用户可以在无线局域网界面201中选择相应SSID的无线局域网，并输入预先设置的接入密码，此时，仍如图2所示，手机100可以向无线路由器200发送鉴权请求(Authentication Request)，当接收到无线路由器200发送的鉴权通过响应(Authentication Response)后，手机100可以向无线路由器200发送连接请求(Association Request)，当接收到无线路由器200发送的连接完成响应(Association Response)后，手机100与无线路由器200建立Wi-Fi连接，从而可以进行数据交互。
示例性的，图4示出了本申请提供的一种Probe Request帧的帧结构实例示意图。如图4所示，Probe Request帧220中可以包括：帧头(即MAC头)221、帧实体(Frame Body)222和帧校验(Frame Check Sequence，FCS)域223。
其中，如图4所示，上述MAC头221可以包括帧控制域(Frame Control)、持续时间/标识(Duration/ID)、地址域(Address)和序列控制域(Sequence Control)等。
其中，帧控制域中可以包括协议版本域(Protocol Version)和类型域。协议版本域用于指示Probe Request帧220所遵循的协议版本，该协议版本通常为0。类型域可以包括Type和Subtype，Type用于指示对应帧为管理帧、 数据帧或者控制帧，Subtype用于指示帧的子类型，例如，当Type＝00时，可以指示对应帧为管理帧。地址域中可以包括源地址、目的地址、传输工作站地址、接收工作站地址等地址信息，其中，目的地址可以为单播地址(Unicast address)、多播地址(Multicast address)、广播地址(Broadcast address)中的任一个。
如图4所示，帧实体222中具体包括SSID字段2221、支持速率(Supported Rates)2222和扩展支持速率(Extended Supported Rates)2223。其中，SSID字段2221中携带有无线局域网的服务集标识，例如，该SSID为图3中所示的Xyzd 204；支持速率2222和扩展支持速率2223用于指示手机或者无线路由器所支持的速率集合。
上述Probe Request帧可以是IEEE802.11中的一种管理帧(Management Frame)。站点13(如上述手机100)还可以通过主动发送Probe Request帧的方式探测Wi-Fi信号。
示例性的，如图5所示，当手机100开启无线局域网功能后，手机可以定期向无线路由器200发送探测请求(Probe Request)帧，此时，手机100发送的Probe Request中的SSID字段为空，即不携带Wi-Fi网络的名称。那么，无线路由器200接收到手机100发送的探测请求后，将其提供的无线局域网的SSID(如Xyzd)携带在探测响应(Probe Response)中发送给手机100，这样，手机100可以探测到无线路由器200提供的无线局域网的SSID(如Xyzd)和手机100在其所在区域内检测到的其他无线局域网的SSID。
可选的，终端在探测到无线局域网之后还可以进一步接入相应的无线局域网。与图2中无线路由器200主动发送Probe Request帧的方式类似的，用户可以在上述无线局域网界面201中选择相应SSID的无线局域网，输入预先设置的接入密码后，仍如图5所示，手机100可以向无线路由器200发送鉴权请求，当接收到无线路由器200发送的鉴权通过响应后，手机100可以向无线路由器200发送连接请求，当接收到无线路由器200发送的连接完成响应后，手机100与无线路由器200建立Wi-Fi连接，从而可以进行数据交互。
基于图2或图5所示的无线局域网络的探测过程，在本申请实施例中，终端(例如上述手机100)探测到或接入某一位置处的Wi-Fi网络后，可以根据该Wi-Fi网络中Wi-Fi信号的强弱变化，识别出用户在该位置处的出行意图。
例如，手机100探测并接入了SSID为“Xyzd”，即Wi-Fi名称为“Xyzd”的Wi-Fi网络，该名称为“Xyzd”的Wi-Fi网络为用户家中设置的Wi-Fi网络。
那么，当手机100检测到名称为“Xyzd”的Wi-Fi网络的Wi-Fi信号由强变弱，直至该Wi-Fi信号的信号强度低于某一预设值时，例如，手机100连接的名称为“Xyzd”的Wi-Fi网络突然断开时，说明用户携带手机100逐渐离开名称为“Xyzd”的Wi-Fi网络的覆盖范围，那么，手机100可确定用户此时具有离开家中的出行意图。进而，手机100可以为用户推荐出发地为：用户家中时的出行信息，例如，在手机100中显示用户家附近的单车数目和位置等出行信息。
这样一来，在GPS信号较弱的位置，手机100可以根据在该位置处Wi-Fi信号的强度变化对用户进行定位，并识别用户在该位置处的出行意图，当用户具有出行意图时，手机100可将该位置处作为出发地为用户推荐相关的出行信息，从而在GPS信号较弱时提高手机100的定位精度，并且为用户提供与其出行意图匹配的较为准确的出行信息。还可以降低因开启GPS定位功能而增加的手机耗电量。
当然，手机100也可以在没有接入上述Wi-Fi网络的情况下确定用户的出行意图，例如，手机100探测到上述名称为“Xyzd”的Wi-Fi网络后，便可以检测该Wi-Fi网络中Wi-Fi信号的信号强度，当该Wi-Fi信号的信号强度低于某一预设值时，也可说明用户携带手机100逐渐离开名称为“Xyzd”的Wi-Fi网络的覆盖范围，因此，手机100可确定用户此时具有离开家中的出行意图。另外，本申请实施例提供的上述站点13，具体可以为手机、可穿戴设备、AR(增强现实)\VR(虚拟现实)设备、平板电脑、笔记本电脑、UMPC(超级移动个人计算机)、上网本、PDA(个人数字助理)等任意终端，本申请实施例对此不作任何限制。
如图6所示，本申请实施例中的终端可以为手机100。下面以手机100为例对实施例进行具体说明。应该理解的是，图示手机100仅是终端的一个范例，并且手机100可以具有比图中所示出的更多的或者更少的部件，可以组合两个或更多的部件，或者可以具有不同的部件配置。
如图6所示，手机100具体可以包括：处理器101、射频(RF)电路102、存储器103、触摸屏104、蓝牙装置105、一个或多个传感器106、Wi-Fi装置107、定位装置108、音频电路109、外设接口110以及电源系统111等部件。这些部件可通过一根或多根通信总线或信号线(图6中未示出)进行通信。本领域技术人员可以理解，图6中示出的硬件结构并不构成对手机的限定，手机100可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
下面结合图6对手机100的各个部件进行具体的介绍：
处理器101是手机100的控制中心，利用各种接口和线路连接手机100的各个部分，通过运行或执行存储在存储器103内的应用程序(以下可以简称App)，以及调用存储在存储器103内的数据，执行手机100的各种功能和处理数据。在一些实施例中，处理器101可包括一个或多个处理单元；举例来说，处理器101可以是华为技术有限公司制造的麒麟960芯片。
射频电路102可用于在收发信息或通话过程中，无线信号的接收和发送。特别地，射频电路102可以将基站的下行数据接收后，给处理器101处理；另外，将涉及上行的数据发送给基站。通常，射频电路包括但不限于天线、至少一个放大器、收发信机、耦合器、低噪声放大器、双工器等。此外，射频电路102还可以通过无线通信和其他设备通信。所述无线通信可以使用任一通信标准或协议，包括但不限于全球移动通讯系统、通用分组无线服务、码分多址、宽带码分多址、长期演进、电子邮件、短消息服务等。
存储器103用于存储应用程序以及数据，处理器101通过运行存储在存储器103的应用程序以及数据，执行手机100的各种功能以及数据处理。存储器103主要包括存储程序区以及存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)；存储数据区可以存储根据使用手机100时所创建的数据(比如音频数据、电话本等)。此外，存储器103可以包括高速随机存取存储器，还可以包括非易失存储器，例如磁盘存储器件、闪存器件或其他易失性固态存储器件等。存储器103可以存储各种操作系统，例如，苹果公司所开发的iOS操作系统，谷歌公司所开发的Android操作系统等。
触摸屏104可以包括触控板104-1和显示器104-2。其中，触控板104-1可采集手机100的用户在其上或附近的触摸事件(比如用户使用手指、触控笔等任何适合的物体在触控板104-1上或在触控板104-1附近的操作)，并将采集到的触摸信息发送给其他器件例如处理器101。
其中，用户在触控板104-1附近的触摸事件可以称之为悬浮触控；悬浮触控可以是指，用户无需为了选择、移动或拖动目标(例如图标等)而直接接触触控板，而只需用户位于终端附近以便执行所想要的功能。在悬浮触控的应用场景下，术语“触摸”、“接触”等不会暗示用于直接接触触摸屏，而是附近或接近的接触。
具体的，可以在触控板104-1内设置两种电容式传感器，即互电容传感器和自电容传感器，这两种电容传感器可以交替地阵列排布在触控板104-1上。其中，互电容传感器用于实现正常传统的多点触控；而自电容传感器能够产生比互电容更为强大的信号，从而检测到距离触控板104-1更远的手指感应。因此，当用户的手指在屏幕上悬停时，如图3所示，由于自电容传感器产生的信号要比互电容传感器产生的信号大，使得手机100可以检测到在屏幕上方，例如，距离触控板104-1上方20mm处用户的手势。
可选的，能够进行悬浮触控的触控板104-1可以采用电容式、红外光感以及超声波等实现。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型来实现触控板104-1。显示器(也称为显示屏)104-2可用于显示由用户输入的信息或提供给用户的信息以及手机100的各种菜单。可以采用液晶显示器、有机发光二极管等形式来配置显示器104-2。触控板104-1可以覆盖在显示器104-2之上，当触控板104-1检测到在其上或附近的触摸事件后，传送给处理器101以确定触摸事件的类型，随后处理器101可以根据触摸事件的类型在显示器104-2上提供相应的视觉输出。虽然在图6中，触控板104-1与显示屏104-2是作为两个独立的部件来实现手机100的输入和输出功能，但是在某些实施例中，可以将触控板104-1与显示屏104-2集成而实现手机100的输入和输出功能。可以理解的是，触摸屏104是由多层的材料堆叠而成，本申请实施例中只展示出了触控板(层)和显示屏(层)，其他层在本申请实施例中不予记载。另外，在本申请其他一些实施例中，触控板104-1可以覆盖在显示器104-2之上，并且触控板104-1的尺寸大于显示屏104-2的尺寸， 使得显示屏104-2全部覆盖在触控板104-1下面，或者，上述触控板104-1可以以全面板的形式配置在手机100的正面，也即用户在手机100正面的触摸均能被手机感知，这样就可以实现手机正面的全触控体验。在其他一些实施例中，触控板104-1以全面板的形式配置在手机100的正面，显示屏104-2也可以以全面板的形式配置在手机100的正面，这样在手机的正面就能够实现无边框的结构。
在本申请实施例中，手机100还可以具有指纹识别功能。例如，可以在手机100的背面(例如后置摄像头的下方)配置指纹识别器112，或者在手机100的正面(例如触摸屏104的下方)配置指纹识别器112。又例如，可以在触摸屏104中配置指纹采集器件112来实现指纹识别功能，即指纹采集器件112可以与触摸屏104集成在一起来实现手机100的指纹识别功能。在这种情况下，该指纹采集器件112配置在触摸屏104中，可以是触摸屏104的一部分，也可以以其他方式配置在触摸屏104中。另外，该指纹采集器件112还可以被实现为全面板指纹采集器件。因此，可以把触摸屏104看成是任何位置都可以进行指纹识别的一个面板。该指纹采集器件112可以将采集到的指纹发送给处理器101，以便处理器101对该指纹进行处理(例如指纹验证等)。本申请实施例中的指纹采集器件112的主要部件是指纹传感器，该指纹传感器可以采用任何类型的感测技术，包括但不限于光学式、电容式、压电式或超声波传感技术等。
手机100还可以包括蓝牙装置105，用于实现手机100与其他短距离的终端(例如手机、智能手表等)之间的数据交换。本申请实施例中的蓝牙装置可以是集成电路或者蓝牙芯片等。
手机100还可以包括至少一种传感器106，比如光传感器、运动传感器以及其他传感器。具体地，光传感器可包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节触摸屏104的显示器的亮度，接近传感器可在手机100移动到耳边时，关闭显示器的电源。作为运动传感器的一种，加速计传感器可检测各个方向上(一般为三轴)加速度的大小，静止时可检测出重力的大小及方向，可用于识别手机姿态的应用(比如横竖屏切换、相关游戏、磁力计姿态校准)、振动识别相关功能(比如计步器、敲击)等；至于手机100还可配置的陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。
Wi-Fi装置107，用于为手机100提供遵循Wi-Fi相关标准协议的网络接入，手机100可以通过Wi-Fi装置107接入到Wi-Fi接入点，进而帮助用户收发电子邮件、浏览网页和访问流媒体等，它为用户提供了无线的宽带互联网访问。在其他一些实施例中，该Wi-Fi装置107也可以作为Wi-Fi无线接入点，可以为其他终端提供Wi-Fi网络接入。
定位装置108，用于为手机100提供地理位置。可以理解的是，该定位装置108具体可以是全球定位系统(GPS)或北斗卫星导航系统、俄罗斯GLONASS等定位系统的接收器。定位装置108在接收到上述定位系统发送的 地理位置后，将该信息发送给处理器101进行处理，或者发送给存储器103进行保存。在另外的一些实施例中，该定位装置108还可以是辅助全球卫星定位系统(AGPS)的接收器，AGPS系统通过作为辅助服务器来协助定位装置108完成测距和定位服务，在这种情况下，辅助定位服务器通过无线通信网络与终端例如手机100的定位装置108(即GPS接收器)通信而提供定位协助。在另外的一些实施例中，该定位装置108也可以是基于Wi-Fi接入点的定位技术。由于每一个Wi-Fi接入点都有一个全球唯一的MAC地址，终端在开启Wi-Fi的情况下即可扫描并收集周围的Wi-Fi接入点的广播信号，因此可以获取到Wi-Fi接入点广播出来的MAC地址；终端将这些能够标示Wi-Fi接入点的数据(例如MAC地址)通过无线通信网络发送给位置服务器，由位置服务器检索出每一个Wi-Fi接入点的地理位置，并结合Wi-Fi广播信号的强弱程度，计算出该终端的地理位置并发送到该终端的定位装置108中。
音频电路109、扬声器113、麦克风114可提供用户与手机100之间的音频接口。音频电路109可将接收到的音频数据转换后的电信号，传输到扬声器113，由扬声器113转换为声音信号输出；另一方面，麦克风114将收集的声音信号转换为电信号，由音频电路109接收后转换为音频数据，再将音频数据输出至RF电路102以发送给比如另一手机，或者将音频数据输出至存储器103以便进一步处理。
外设接口110，用于为外部的输入/输出设备(例如键盘、鼠标、外接显示器、外部存储器、用户识别模块卡等)提供各种接口。例如通过通用串行总线(USB)接口与鼠标连接，通过用户识别模块卡卡槽上的金属触点与电信运营商提供的用户识别模块卡(SIM)卡进行连接。外设接口110可以被用来将上述外部的输入/输出外围设备耦接到处理器101和存储器103。
手机100还可以包括给各个部件供电的电源装置111(比如电池和电源管理芯片)，电池可以通过电源管理芯片与处理器101逻辑相连，从而通过电源装置111实现管理充电、放电、以及功耗管理等功能。
尽管图6未示出，手机100还可以包括摄像头(前置摄像头和/或后置摄像头)、闪光灯、微型投影装置、近场通信(NFC)装置等，在此不再赘述。
以下，将以上述手机100为例，结合具体实施例详细阐述本申请实施例提供的一种信息推荐方法，如图7所示，该方法包括：
301、手机从探测到的N个Wi-Fi网络中选择目标Wi-Fi网络，N＞0。
其中，手机探测其所在位置处覆盖的Wi-Fi网络的方法可参考图2或图5的相关描述，故此处不再赘述。
需要说明的是，手机探测到Wi-Fi网络后可以自动或由用户手动接入探测到的Wi-Fi网络，例如，手机已经接入过名称为“Xyzd”的Wi-Fi网络，那么，当手机再次探测到该名称为“Xyzd”的Wi-Fi网络时，由于手机内存储有该Wi-Fi网络的接入密码，因此，手机可自动接入该Wi-Fi网络。当然，手机探测到Wi-Fi网络后也可以不接入探测到的Wi-Fi网络，例如，手机处于黑屏状态时，手机内的Wi-Fi装置可在后台探测当前覆盖的Wi-Fi网络，但无需接 入探测到的Wi-Fi网络，本申请实施例对此不作任何限制。
另外，手机可通过其Wi-Fi装置(例如图6中的Wi-Fi装置107)探测当前覆盖的Wi-Fi网络，此时，手机的处理器(例如图6中的处理器101)可处于休眠状态或低功耗状态，从而降低手机的耗电量。
具体的，当手机探测到当前所处位置覆盖的N个Wi-Fi网络时，例如，这N个Wi-Fi网络包括：名称为“Xyzd”的Wi-Fi网络，名称为“地铁公共Wi-Fi”的Wi-Fi网络以及名称为“Zhangsan”的Wi-Fi网络。那么，手机可以从这3个Wi-Fi网络中选择一个作为目标Wi-Fi网络，该目标Wi-Fi网络可以为用户预先设置的Wi-Fi网络，例如，用户家中的Wi-Fi网络(名称为“Tom的家”)，也可以为用户曾经接入过的Wi-Fi网络，例如，用户在**路的肯德基吃饭时接入的名称为“肯德基123”的Wi-Fi网络，或者，用户在**地铁站接入的名称为“深圳地铁”的Wi-Fi网络。
示例性的，手机探测到的N个Wi-Fi网络中可能有多个Wi-Fi网络均为预先设置或曾经接入过的Wi-Fi网络，例如，用户在**地铁站时，其手机探测到名称为“深圳地铁”的Wi-Fi网络和名称为“肯德基123”的Wi-Fi网络均为曾经接入过的Wi-Fi网络，此时，手机可以分别检测这两个Wi-Fi网络中Wi-Fi信号的强度，并将Wi-Fi信号强度最大的Wi-Fi网络，例如，名称为“深圳地铁”的Wi-Fi网络，作为上述目标Wi-Fi网络。
又或者，当手机探测到当前覆盖的N个Wi-Fi网络后，如果用户进入图3所示的无线局域网界面201选择某个Wi-Fi网络并接入，则手机可以将已接入的Wi-Fi网络作为上述目标Wi-Fi网络。
又或者，可以预先在手机内存储上述目标Wi-Fi网络的SSID，例如，预先存储的SSID为“深圳地铁”，那么，当手机探测到当前覆盖的N个Wi-Fi网络后，手机可以查找这N个Wi-Fi网络的SSID中是否包含预先存储的SSID为“深圳地铁”的Wi-Fi网络，如果查找到SSID为“深圳地铁”的Wi-Fi网络，则将该SSID为“深圳地铁”的Wi-Fi网络作为上述目标Wi-Fi网络。
也就是说，在步骤301中，手机通过选择目标Wi-Fi网络可以确定出用户当前的地理位置，即对用户进行定位，这样，在一些GPS信号较弱，或者手机电量不足的场景下，手机可以通过其Wi-Fi装置较为准确的对用户进行定位，同时降低手机的耗电量。
需要说明的是，上述目标Wi-Fi网络可以为一个或多个，本申请实施例对此不作任何限制。
302、手机检测上述目标Wi-Fi网络的信号强度，得到T时间内目标Wi-Fi的信号变化情况，T＞0。
在步骤302中，当手机确定目标Wi-Fi网络后，可以通过检测在该目标Wi-Fi网络中的Wi-Fi信号强度，获取到该目标Wi-Fi网络的信号强度在T时间内的变化情况。
其中，Wi-Fi信号的强度可以用dB(分贝)来表示，用于指示Wi-Fi信号发射功率的增益；也可以用dBm(分贝毫瓦)来表示，用于指示Wi-Fi信 号发射功率的绝对值。又或者，手机还可以计算目标Wi-Fi网络中目标Wi-Fi信号的接收信号强度指示(Received signal strength indicator，RSSI)值，通过目标Wi-Fi信号的RSSI值表示目标Wi-Fi的信号强度，本申请实施例对此不作任何限制。
示例性的，手机确定目标Wi-Fi网络是名称为“深圳地铁”的地铁公共Wi-Fi网络，进而，手机可以周期性的检测该目标Wi-Fi网络在不同时刻的M(M＞1)个Wi-Fi信号强度值。例如，可以以5秒为周期，手机可以检测到未来20秒内名称为“深圳地铁”的Wi-Fi网络的信号强度，得到4个目标Wi-Fi网络的信号强度值。这4个目标Wi-Fi网络的信号强度值反映了20秒内名称为“深圳地铁”的Wi-Fi网络的信号变化情况，同时，目标Wi-Fi的信号变化情况也反映出了用户在目标Wi-Fi网络的覆盖范围内的移动规律。
303、当上述目标Wi-Fi的信号强度由强变弱时，手机确定用户在第一位置的出行意图。
上述第一位置即为步骤301中与手机确定的目标Wi-Fi网络覆盖的区域。例如，如图8所示，当目标Wi-Fi网络为名称为“Tom的家”的Wi-Fi网络1时，与其对应的第一位置即为Wi-Fi网络1的网络覆盖区域，即Tom的家(例如，中山大街88号)；如图9所示，当目标Wi-Fi网络为名称为“肯德基123”的Wi-Fi网络2时，与其对应的第一位置即为Wi-Fi网络2的网络覆盖区域，即该肯德基所在的地理位置(例如，西安路38号)；如图10所示，当目标Wi-Fi网络为名称为“深圳地铁”的Wi-Fi网络3时，与其对应的第一位置即为Wi-Fi网络3的网络覆盖区域，即该地铁站所在的地理位置(例如，五和大道47号)。
由于Wi-Fi网络发出的Wi-Fi信号通常是以中心向四周辐射的形式传播的，因此，当检测到上述目标Wi-Fi的信号强度由强变弱时，说明用户可能携带手机逐渐远离目标Wi-Fi网络所覆盖的第一位置，此时，可触发手机确定用户在第一位置是否具有的出行意图，即用户是否准备离开该第一位置。
示例性的，手机中可预先存储一个信号强度阈值，那么，当检测到目标WiFi网络的信号强度小于上述信号强度阈值时，说明用户此时刚离开第一位置，因此，手机可确定用户此时在第一位置具有的出行意图。
又例如，如果手机已经接入上述目标Wi-Fi网络，那么，当手机接收到目标Wi-Fi网络中Wi-Fi信号的信号强度低于某一信号强度阈值时，手机会自动断开该目标Wi-Fi网络，此时，手机也可确认用户离开第一位置出行意图。
又例如，还可以在手机中预先存储一个信号衰减速率的速率阈值，那么，当检测到在预设时间，例如，在10秒内，如果步骤302中获取到的M个目标Wi-Fi信号强度的衰减速率大于上述速率阈值时，说明用户此时想要离开第一位置，因此，手机可确定用户此时在第一位置具有的出行意图。
又例如，手机中也可预先存储用于指示用户离开或准备离开上述第一位置时的信号衰减模型，例如，该信号衰减模型包括：根据用户步行的速度确定出的用户离开第一位置过程中目标Wi-Fi信号的衰减速率范围，并根据目 标Wi-Fi的信号发射功率确定用户离开第一位置时的最低信号强度阈值。
那么，在步骤303中，手机可以将步骤302中获取到的M个目标Wi-Fi信号强度与预设的信号衰减模型进行比较。当这M个目标Wi-Fi信号强度所反映的信号衰减速率位于上述信号衰减模型中的衰减速率范围，且这M个目标Wi-Fi信号强度中最后检测到的目标Wi-Fi信号强度低于上述最低信号强度阈值时，手机可确定用户在该第一位置的出行意图，即用户准备离开第一位置。
仍如图8所示，用户Tom在家中时，其手机将探测到的名称为“Tom的家”的Wi-Fi网络1作为目标Wi-Fi网络，进而，手机可以持续检测Wi-Fi网络1的Wi-Fi信号强度。在Tom携带手机从家中的位置A移动至家外的位置B的过程中，手机可以检测到上述Wi-Fi网络1的Wi-Fi信号强度由强变弱，当检测到上述Wi-Fi网络1的Wi-Fi信号强度小于上述信号强度阈值时，手机可以确定出用户Tom从家中离开这一出行意图。
又例如，如图9所示，用户Tom在西安路38号的肯德基餐厅时，其手机将探测到的名称为“肯德基123”的Wi-Fi网络2作为目标Wi-Fi网络，进而，手机可以持续检测Wi-Fi网络2的Wi-Fi信号强度。在Tom携带手机从该肯德基餐厅内的位置A移动至肯德基餐厅外的位置B的过程中，如果手机检测到上述Wi-Fi网络2的Wi-Fi信号强度在20秒内的衰减速率大于上述速率阈值，则手机可以确定出用户Tom从西安路38号的肯德基餐厅离开这一出行意图。
又例如，如图10所示，用户Tom在五和地铁站时，其手机将探测到的名称为“深圳地铁”的Wi-Fi网络3作为目标Wi-Fi网络，进而，手机可以持续检测Wi-Fi网络3的Wi-Fi信号强度。在Tom携带手机从五和地铁站的位置A移动至靠近出站口的位置B的过程中，如果手机检测到上述Wi-Fi网络3的Wi-Fi信号强度由强变弱，且其Wi-Fi信号强度的衰减规律满足上述信号衰减模型，此时，手机可以确定出用户Tom从五和地铁站离开这一出行意图。
可以看出，在上述实施例中，手机通过开启Wi-Fi装置便可以定位出用户所在的第一位置，并识别出用户在第一位置处的出行意图，使得手机在GPS信号不好的应用场景下也可以实现对用户的准确定位功能，并且可减轻手机因开启GPS定位功能所带来的功耗开销。
进一步地，当手机检测到上述目标Wi-Fi的信号强度由强变弱，或者，检测到上述目标Wi-Fi的信号的衰减规律满足上述信号衰减模型时，手机还可以进一步获取用于指示当前手机所处的应用场景的场景描述数据，根据这些场景描述数据确定当前的应用场景是否满足预设的辅助条件，即通过一些辅助措施进一步对用户离开第一位置的出行意图，以提高手机确定用户出行意图时的准确性。
例如，手机内可以预先存储上述第一位置处的小区ID名单，那么，以图10为例，当手机检测到上述目标Wi-Fi的信号强度由强变弱时，还可触发手机通过调制解调器(modem)获取当前的小区ID，当获取到的小区ID位于预 先存储的五和地铁站周边的小区ID名单中时，可确认用户从五和地铁站离开的出行意图。
又例如，手机在检测上述目标Wi-Fi信号强度的同时，该手机或与该手机相连的可穿戴设备还可以检测其运动状态，并且，手机或者可穿戴设备还可以将不同时刻检测到的运动状态作为运动状态信息记录下来。那么，仍以图10为例，当手机在检测到上述目标Wi-Fi的信号强度由强变弱时，还可以触发手机进一步查询最近一段时间内，例如，最近20秒内，手机或者可穿戴设备存储的运动状态信息，例如，当查询到手机最近20秒内的运动状态从每秒50公里的速度转变为每秒1米的速度，则可认为用户从乘车态转换为步行态，那么，手机可确认用户从五和地铁站离开的出行意图。
又例如，手机在检测上述目标Wi-Fi信号强度的同时，还可以检测在预设时间内手机是否执行NFC刷卡行为。如图11所示，用户可使用NFC功能刷卡出地铁站，此时，手机内的NFC模块会上报一个NFC刷卡事件，手机可将检测到的NFC刷卡事件记录下来，形成NFC刷卡事件的记录信息。那么，仍以图10为例，当手机在检测到上述目标Wi-Fi的信号强度由强变弱后，可触发手机进一步从上述记录信息中查询最近1分钟内手机是否上报过NFC刷卡事件，那么，如果查询到最近1分钟内的NFC刷卡事件，则手机可进一步确认用户从五和地铁站离开的出行意图。
又例如，手机在检测到上述目标Wi-Fi信号强度由强变弱时，还可以打开手机的麦克风检测当前的环境音，通过获取到的环境音识别手机所处的环境是否为公共场所，当识别出手机所处的环境为公共场所时，手机可进一步确认用户从第一位置离开的出行意图。
当然，手机还可以开启GPS定位功能进一步确认用户从第一位置离开的出行意图，本申请实施例对此不作任何限制。
手机通过执行上述辅助措施可以进一步确认用户离开第一位置的出行意图，避免因为目标WiFi网络的WiFi信号不稳定而导致手机错误确认用户出行意图的现象，从而提高手机确定用户出行意图时的准确性，以便后续为用户提供更加准确的出行信息。
另外，当上述目标Wi-Fi网络有多个时，对于每一个目标Wi-Fi网络，手机都可以使用上述方法确定用户的出行意图。例如，当地铁站或高铁站较大时，用户在出站的过程中可能会经过多个Wi-Fi网络覆盖的区域，这多个Wi-Fi网络的SSID可能均为手机预先存储的目标Wi-Fi网络的SSID。那么，对于每一个目标Wi-Fi网络，当检测到该目标Wi-Fi网络的Wi-Fi信号强度满足上述有强变弱的预设规律时，即可触发手机确认用户离开其网络覆盖区域的意图；当然，也可以设置当这多个目标Wi-Fi网络的信号强度均满足上述有强变弱的预设规律时，触发手机确认用户离开地铁站或高铁站的出行意图，本申请实施例对此不作任何限制。
可选的，上述步骤301-303可以是手机在锁屏或黑屏状态下自动执行的，也就是说，手机可以在用户无感知的情况下检测目标Wi-Fi网络的信号强度， 并根据信号强度的变化情况确定用户的出行意图，以便手机在用户无感知的情况下快速及时的为用户确定准确的出行信息，这样，当用户唤醒手机后可以在第一时间获取到该出行信息，从而提高用户的出行效率和出行体验。
304、手机向用户提示与上述第一位置相关联的出行信息。
具体的，在步骤304中，手机确定出用户在上述第一位置的出行意图后，可以将该第一位置或第一位置附近的车站、出入口等标志性地理位置作为出发地，生成相应的出行信息推荐给用户。
在一种可能的设计方法中，手机可以在显示界面(例如手机的下拉菜单、手机的负一屏菜单)中，将确定出的用户当前所在的第一位置提示给用户。
在另一种可能的设计方法中，手机还可以与公共交通服务商的服务器连接，获取以上述第一位置为出发地的交通工具信息，并将该交通工具信息作为上述出行信息显示在手机上，从而将出行信息推荐给用户。
例如，手机确定出用户在五和地铁站C口的出行意图后，可与共享单车APP的服务器交互，获取位于五和地铁站C口附近的单车数目和位置等信息作为上述出行信息。进而，可在手机的下拉菜单401中显示如图12所示的界面，其中，下拉菜单401中显示有提示信息402，该提示信息402用于提示用户查看五和地铁站C口附近的单车。那么，当用户点击该提示信息402后，手机可调用共享单车APP的应用程序编程接口(Application Programming Interface，API)，跳转至共享单车APP中查看附近单车功能的应用界面，显示五和地铁站C口附近的单车数目和位置等出行信息，使得用户能够及时准确的获取到手机推荐的出行信息。
又例如，手机确定出用户在五和地铁站C口的出行意图后，可与共享单车APP的服务器交互，为用户提供单车预约服务。此时，如图13所示，手机可以在其负一屏菜单501中显示提示信息502，该提示信息402用于提示用户预约五和地铁站C口附近的单车。那么，当用户点击该提示信息502后，手机可调用共享单车APP的API，跳转至如图14所示的单车预约功能的应用界面503，并为用户显示在五和地铁站C口附近的单车预约结果，使得用户能够根据手机推荐的出行信息快速预约单车，提高出行效率。
在另一种可能的设计方法中，手机还可以将上述第一位置作为出发地，为用户规划相应的出行路线，并将规划的出行路线作为上述出行信息显示在手机上，从而将出行信息推荐给用户。
例如，手机确定出用户在五和地铁站的出行意图后，如果该五和地铁站位于用户设置的下班回家路径上，且当前时间(如图15所示的18:11)处于预先设置的下班时间范围内，则可以确定用户出行的目的地(即第二位置)为用户的家。那么，手机可以自动为用户规划从五和地铁站回家的路线(例如，用户预先在地图应用中已经设置家的具体地理位置)。此时，如果手机处于黑屏状态，则如图15所示，手机可以点亮手机屏幕，并在手机呈现的锁屏界面601上显示提示信息602，该提示信息602用于提示用户查看手机已经规划好的从五和地铁站回家的路线。那么，当用户点击该提示信息602后，手 机可调用百度地图APP的API，跳转至从五和地铁站回家的路线导航界面，使得用户能够根据手机推荐的出行信息快速确定出行路线，提高出行效率。
又例如，手机确定出用户在五和地铁站的出行意图后，还可以获取第一位置附近的公交信息，例如，与五和地铁站距离最近的公交站为五和站。那么，手机可以获取路过五和站的一路或多路公交车的实时公交信息，以M461路公交车为例，该实时公交信息可以包括距离五和站最近的公交车的位置和站点信息。进而，如图16所示，手机可以将获取到的实时公交信息701显示在手机当前的显示界面702中，以便用户查看和选择相应的公交出行。
当然，如果该五和地铁站位于用户设置的下班回家路径上，且当前时间(如图16所示的18:11)处于预先设置的下班时间范围内，则手机可以仅获取或显示经过五和站和用户家的一路或多路公交车的实时公交信息，本申请实施例对此不作任何限制。
另外，手机还可以通过语音、震动等多种形式向用户提示上述与第一位置相关联的出行信息，本申请实施例对此不作任何限制。
进一步地，用户还可通过进入图17所示的设置界面，手动开启或关闭上述实施例提供的出行信息推荐功能。当用户开启该出行信息推荐功能后，还可以手动添加相应的目标Wi-Fi，当然，手机也可以在每次接入Wi-Fi网络时提示用户是否添加该Wi-Fi网络为出行信息推荐时的目标Wi-Fi，本申请实施例对此不作任何限制。
另外，手机还可以手动定制符合用户出行习惯或出行需求的出行信息，例如，用户打开图17中所示的“公交信息”和“附近的单车”这两个选项时，手机在确定用户在第一位置的出行意图后，会同时提供第一位置附近的公交信息，以及第一位置附近的单车这两项出行信息。
进一步地，当用户选择添加目标Wi-Fi网络的设置功能时，如图18所示，手机可以为用户提供手动添加目标Wi-Fi网络和自动下载目标Wi-Fi网络这两种添加方式。在手动添加目标Wi-Fi网络时，用户可以手动输入待添加的目标Wi-Fi网络的SSID以及IP地址等描述信息；在自动下载加目标Wi-Fi网络时，由于与手机相连的服务器可以定期更新各个城市的地铁站、机场以及火车站等位置的公共Wi-Fi网络，因此，用户可以选择其所需的目标Wi-Fi网络，由手机从服务器下载用户选择的目标Wi-Fi网络的描述信息，以便后续根据该目标Wi-Fi网络的信号强度变化情况为用户推荐相关的出行信息。
至此，通过上述步骤301-304，手机可以通过检测目标Wi-Fi网络的信号强度变化，确定出用户在第一位置的出行意图，进而为用户推荐与该第一位置相关联的各类出行信息，这样，当用户离开第一位置时可以及时在手机上获取到与自身出行意图匹配的出行信息，从而提高用户的出行效率和出行体验。
