本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其他步骤或单元。

本申请实施例所涉及到的电子设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(user equipment，UE)，移动台(mobile station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为电子设备。下面对本申请实施例进行详细介绍。
请参照图1，本申请实施例提供一种导航方法的流程示意图。该导航方法应用于电子设备，该电子设备可采用链路聚合技术。该链路聚合是指使设备可以同时使用两个或两个以上的网口同时进行上网。比如在手机上通过链路聚合的同时使用无线保真(Wireless-Fidelity，Wi-Fi)网络和移动数据网络进行网络访问。其中，Wi-Fi网络又称为无线网络。
本申请对于电子设备连接的多个网络不做限定。如图2所示的网络构架图，电子设备200可与第一基站202提供移动数据网络连接。该移动数据网络可提供不同频段的网络。例如：第二代手机移动规格(2-Generation wireless telephone technology，2G)网络、第三代移动通信技术(3rd-Generation，3G)网络、第四代移动通信技术(the 4th Generation mobile communication technology，4G)网络、第五代移动通信技术(5th-Generation，5G)网络。电子设备200也可以与不同设备提供的无线网络连接。例如：第一热点设备204提供Wi-Fi网络和蓝牙网络、第一路由器206提供2.4GHz的Wi-Fi网络和5GHz的Wi-Fi网 络。
无线网络为了其安全性，设置了身份验证步骤。即在电子设备接入该无线网络时，该无线网络需验证电子设备的身份信息。在验证成功时与电子设备建立网络连接。例如：无线网络的命名为sanhuan，验证密码为65498231。则当且仅当电子设备提交65498231时，该无线网络与电子设备建立连接。
具体的，如图1所示，一种导航方法，包括：
S101：确定电子设备的导航路线。
在本申请中，导航路线可以是针对行车的路线，也可以是针对行人的路线，在此不做限定。若电子设备与车载设备连接、或电子设备处于车库的位置等情况，可首先确定针对行车的路线。该导航路线可以是电子设备根据电子设备所搜索到的多个参考路线所自动推荐的导航路线，也可以是用户根据电子设备显示的多个参考路线所选择的导航路线。
在一种可能的示例中，所述确定所述电子设备的导航路线包括：确定所述电子设备对应的起点位置和终点位置；搜索所述起点位置和所述终点位置对应的多个参考路线；确定所述多个参考路线中每一参考路线对应的评价值，得到多个评价值；选取所述多个评价值中的最大值对应的参考路线为所述导航路线。
其中，起点位置即导航操作的开始位置，可以是电子设备的当前位置，也可以是用户在电子设备中输入的位置。终点位置即导航操作的结束位置，可以是用户在电子设备中输入的位置，也可以是共享路线中的一个位置，在此均不作限定。当前位置可根据电子设备的定位模块进行确定，也可根据搜索到的网络设备的网速确定电子设备与该网络设备之间的距离，以及根据该网络设备的信号方向确定电子设备的当前位置。
该定位模块可以是全球定位系统(Global Positioning System，GPS)模块或无线局域网(Wireless Local Area Networks，WLAN)模块。其中，GPS模块利用GPS定位卫星，在全球范围内实时进行定位、导航。WLAN模块利用射频技术，使用电磁波，在空中进行通信连接。其定位方法可依据所连入的热点设备，例如：无线路由器或开启热点的电子设备等。
在本申请中，多个参考路线为从起点位置到终点位置对应的多个不同的路线。本申请对于确定各个参考路线对应的评价值的方法不做限定，可根据各个 参考路线对应的路线长度、限速、拥堵状态、网络状态、收费情况、用户的熟悉程度等多个维度进行确定，以此确定各个参考路线的优劣。
可以理解，先确定电子设备对应的起点位置和终点位置，然后根据起点位置和终端位置搜索多个参考路线，再确定各个参考路线的评价值，选取多个评价值中的最大值对应的参考路线为导航路线。如此，可提高用户的导航体验。
在一种可能的示例中，所述确定所述多个参考路线中每一参考路线对应的评价值，得到多个评价值，包括：确定所述电子设备的当前时间；根据所述当前时间确定目标参考路线中各个目标参考路段对应的通行速率；确定所述目标参考路线中各个目标参考路段对应的路线长度；根据所述目标参考路线中各个目标参考路段对应的路线长度和通行速率确定所述目标参考路线的预估时长；根据所述预估时长确定所述目标参考路线的评价值。
其中，当前时间可根据电子设备的时间管理器进行确定。
目标参考路线为所述多个参考路线中的任一参考路线，目标参考路线包括多个目标参考路段。
通行速率用于描述目标参考路段的拥堵状态，即通行速率越大，表示目标参考路段越不拥堵，通行速率越小，表示目标参考路段越拥堵。在实际应用中，通行速率应小于或等于目标参考路段对应的限制速率。
可以理解，在本申请中以目标参考路线描述评价值的确定方法，多个参考路段中的其它参考路段可参考此方法，在此不再赘述。具体的，由于不同时段各个路段的拥堵状态不同，尤其是上下班的高峰期，周末或节假日，可根据当前时间确定各个目标参考路段的拥堵状态。即确定电子设备在各个目标参考路段的通行速率，再根据通行速率和该目标参考路段的路线长度预估该目标参考路段的通行时长以得到目标参考路线的预估时长，则评价值越大，对应的参考路线的预估时长越短，而导航路线对应的评价值为多个评价值中的最大值，从而可缩短导航路线的通行时长，提高了用户的导航体验。
S102：确定所述导航路线中的目标路段，在所述目标路段所述电子设备的第一网络速率小于预设阈值。
在本申请中，预设阈值不做限定，可根据电子设备当前所需的最小网络速率进行确定。导航路线包括多个导航路段，若电子设备在其中的一个导航路段 对应的第一网络速率小于预设阈值，则将该导航路段作为目标路段，目标路段的数量可为一或多，在此不做限定。
在一种可能的示例中，所述导航路线包括多个导航路段，所述确定所述导航路线中的目标路段，包括：获取在所述多个导航路段中每一导航路段所述电子设备使用移动数据网络的历史使用记录集，得到多个历史使用记录集；根据所述多个历史使用记录集确定所述多个导航路段中每一导航路段的网络速率，得到多个第二网络速率；确定所述多个第二网络速率中小于所述预设阈值的第二网络速率对应的导航路段为所述目标路段。
其中，历史使用记录集包括多个在对应路段中电子设备使用移动数据网络的历史使用记录，每一历史使用记录可包括以下至少一项：使用时长、网络速率、使用网络数量、网络掉线率等。
可以理解，先获取在各个导航路段电子设备使用移动数据网络的历史使用记录集，然后根据多个历史使用记录集确定各个导航路段的网络速率以得到多个第二网络速率，然后将小于预设阈值的第二网络速率对应的导航路段确定为目标路段。如此，依据历史使用记录集确定各个导航路段的第二网络速率，可提高确定第二网络速率的准确性，即便于提高确定目标路段的准确性。
本申请对于根据历史使用记录集确定第二网络速率的方法不做限定，在一种可能的示例中，所述根据所述多个历史使用记录集确定所述多个导航路段中每一导航路段的网络速率，得到多个第二网络速率，包括：根据在参考导航路段所述电子设备使用移动无线网络对应的历史使用记录集确定所述电子设备对应的多个天线中每一天线中的网络速率和使用次数，得到多个参考网络速率和多个使用次数；根据所述参考导航路段对应的历史使用记录集统计所述多个天线中每一天线对应的使用次数，得到多个使用次数；根据所述多个使用次数确定所述多个天线中每一天线对应的权值，得到多个权值；根据所述多个参考网络速率和所述多个权值确定所述参考导航路段对应的第二网络速率。
其中，所述参考导航路段为所述多个路段中的任一路段。
多个天线可以为贴片天线、柔性电路板(Flexible Printed Circuit，FPC)天线、基于激光直接成型技术(Laser Direct Structuring，LDS)的天线、基于平面印刷工艺(Print Direct Structuring，PDS)的天线等。其类型可包括支持 2G、3G、4G或5G频段等支持移动数据网络的天线。
可以理解，在本申请中以参考导航路段描述第二网络速率的确定方法，多个导航路段中的其它导航路段可参考此方法，在此不再赘述。具体的，根据在参考导航路段所述电子设备使用移动无线网络对应的历史使用记录集分别确定电子设备对应的各个天线的参考网络速率，和各个天线的使用次数。然后根据各个天线的使用次数确定对应天线的权值以得到多个权值。最后根据各个天线的参考网络速率和权值确定该参考导航路段对应的第二网络速率。如此，基于各个天线在该参考导航路段的参考网络速率以及使用次数确定第二网络速率，可提高确定第二网络速率的准确性。
在一种可能的示例中，所述方法还包括：确定所述多个导航路段中每一导航路段的限制速度，得到多个限制速度；根据所述多个限制速度确定所述预设阈值。
其中，限制速度用于描述导航路段中的最低速度或最高速度。在该示例中，可将多个限制速度中的最小值设置为预设阈值，也可以将多个限制速度中的平均值设置为预设阈值，还可将平均值对应的比例值设置为预设阈值等等，在此也不做限定。
可以理解，根据导航路线中各个导航路段的限制速度确定预设阈值，可便于根据预设阈值选取目标路段的准确性。
S103：在所述目标路段连接所述目标路段对应的预设无线网络，并基于所述预设无线网络播放所述目标路段对应的导航信息。
在本申请中，预设无线网络可以为该目标路段中的备选无线网络。本申请对于确定预设无线网络的方法不做限定，在一种可能的示例中，所述方法还包括：搜索所述目标路段对应的多个参考无线网络；获取所述多个参考无线网络中每一参考无线网络的性能参数，得到多个性能参数；根据所述多个性能参数获取所述多个参考无线网络中每一参考无线网络的网络质量值，得到多个网络质量值；确定所述多个网络质量值中的最大值对应的参考无线网络为所述预设无线网络。
其中，参考无线网络为目标路段中已经验证成功或不需要验证的安全网络，其中，安全网络可以是预设数据库中未被登记的网络。
性能参数可以包括以下至少一项网络掉线率、网络速率、接收信号强度、发射功率等多个网络维度信息，在此不做限定。
网络质量值用于描述每一参考无线网络在目标路段的网络质量。网络质量值可依据电子设备预先存储的各个网络维度信息对应的权值，与每一网络维度信息对应的评价值之间进行加权，以得到该网络质量值。如此，考虑了每一网络维度信息在该网络维度信息之间的评价值，以及各个网络维度信息对应的权值，可提高确定第一网络质量值的准确性。
可以理解，先搜索目标路段可与电子设备连接的多个参考无线网络，再确定各个参考无线网络的性能参数以得到多个性能参数。然后，根据各个性能参数获取对应参考无线网络的网络质量值以得到多个网络质量值。最后将多个网络质量值中的最大值作为预设无线网络。如此，可提高基于预设无线网络进行导航的网络质量。
在如图1所示的导航方法中，先确定电子设备的导航路线，再确定所述导航路线中所述电子设备的第一网络速率小于预设阈值的目标路段。然后，在所述目标路段连接所述目标路段对应的预设无线网络，并基于所述预设无线网络播放所述目标路段对应的导航信息。如此，电子设备基于预设无线网络进行导航，可提高电子设备进入该目标路段的网络质量，提高导航的网络质量。
在一种可能的示例中，所述方法还包括：确定所述预设无线网络的第三网络速率；若所述第三网络速率小于所述预设阈值，则根据在所述目标路段所述电子设备使用移动无线网络对应的历史使用记录集获取所述目标路段对应的行驶信息；根据所述行驶信息生成所述导航信息；在所述电子设备到达所述目标路段的起始位置时，播放所述导航信息。
其中，行驶信息可包括目标路段的行驶方向、限制速率、行驶速率等。
可以理解，先确定预设无线网络的第三网络速率，若第三网络速率小于预设阈值，则根据在目标路段电子设备使用移动数据网络对应的历史使用记录集获取与目标路段对应的行驶信息，再根据该行驶信息生成目标路段对应的导航信息，在电子设备到达目标路段的起始位置时，播放该导航信息。如此，依据之前存储的行驶信息生成目标路段的离线导航信息，提高了网络故障处理能力。
在本申请中，第三网络速率可根据电子设备的网速检测模块进行获取，也 可根据预设无线网络对应的网络设备与所述电子设备之间的相对距离，以及目标路段对应的网络参数进行获取，在此不做限定。
在一种可能的示例中，所述确定所述预设无线网络的第三网络速率，包括：确定所述预设无线网络对应的网络设备的性能参数；根据所述网络设备的性能参数确定第四网络速率；确定所述网络设备与所述电子设备之间的相对距离；确定所述电子设备在所述目标路段的行驶速率；根据所述相对距离和所述行驶速率确定网络速率影响值；确定所述网络速率影响值和所述第四网络速率之间的乘积为所述第三网络速率。
其中，预设无线网络对应的网络设备的性能参数也可包括网络掉线率、网络速率、接收信号强度、发射功率等多个网络维度信息，在此不做限定。
本申请对于如何确定网络设备和电子设备之间的相对距离不做限定，在一种可能的示例中，与所述网络设备建立邻近感知网络连接，基于所述邻近感知网络的距离测量方式检测所述网络设备与所述电子设备之间的相对距离。
其中，邻近感知网络(Neighborhood Aware Networking，NAN)，又称无线保真邻近感知网络(Wireless Fidelity Alliance，Wi-Fi Alliance)，在本申请实施例中采用NAN进行描述。该NAN功能主要用于实现实时高效发现机制，从而扩展Wi-Fi功能，改进此时此地的应用体验。
NAN的距离测量方式ranging用于检测建立NAN网络的设备之间的距离。该距离可由电子设备获取，也可由网络设备获取，在此不做限定。
可以理解，若预设无线网络对应的网络设备可与电子设备建立NAN连接，则电子设备可基于NAN的ranging获取网络设备与电子设备之间的相对距离，也可由网络设备基于NAN的ranging获取该网络设备与电子设备之间的相对距离，再向电子设备发送该相对距离。
在本申请中，行驶速率可根据目标路段对应的行驶信息进行确定，还可根据上述的确定多个评价值中的方法，将目标路段对应的通行速率作为行驶速率，在此不做限定。
可以理解，先确定预设无线网络对应的网络设备的性能参数，再根据该性能参数确定电子设备可使用预设无线网络所预期的第四网络速率。然后确定预设无线网络对应的网络设备与电子设备之间的相对距离，以及电子设备在目标 路段的行驶速率。由于移动速率可影响无线网络的网络速率，例如：在高速行驶的火车上，信号难以稳定，且与网络设备的距离越远，网络信号越弱。因此，在本申请中，根据预设无线网络对应的网络设备与所述电子设备之间的相对距离和电子设备在所述目标路段的行驶速率确定网络速率影响值。最后根据第四网络速率和网络速率影响值之间的乘积确定第三网络速率，则在本申请中，考虑了行驶速率和相对距离对于网络速率的影响，便于提高确定第三网络速率的准确性。
