Description
本发明涉及移动终端应用技术，尤其涉及一种控制无线局域网后台扫描的方法和装置。The present invention relates to mobile terminal application technologies, and in particular, to a method and apparatus for controlling background scanning of a wireless local area network.
随着移动互联网技术的迅猛发展，移动终端如智能手机和平板电脑得到了高速发展和广泛应用。移动终端普遍支持无线局域网通信功能，从而支持通过连接到无线局域网访问网络如因特网来获取信息。目前，为了改善移动终端中使用无线局域网的用户体验，移动终端中普遍支持无线局域网后台扫描。当启动无线局域网后台扫描时，移动终端会定期(例如，每分钟一次)扫描无线局域网热点即能够接入的无线局域网，当确定出无线局域网热点为之前鉴权的无线局域网热点即之前成功连接过的无线局域网热点时，移动终端自动连接到该无线局域网热点。With the rapid development of mobile Internet technology, mobile terminals such as smart phones and tablets have been rapidly developed and widely used. Mobile terminals generally support wireless local area network communication functions to support access to information by connecting to a wireless local area network such as the Internet. Currently, in order to improve the user experience of using a wireless local area network in a mobile terminal, wireless local area network background scanning is generally supported in mobile terminals. When the wireless LAN background scan is started, the mobile terminal scans the wireless local area network hotspot, that is, the wireless local area network that can be accessed periodically (for example, once per minute), and successfully determines that the wireless local area network hotspot is the previously authenticated wireless local area network hot spot. When the WLAN hotspot is hot, the mobile terminal automatically connects to the WLAN hotspot.
无线局域网后台扫描虽然能够改善动终端中使用无线局域网的用户体验，但是当开启无线局域网后台扫描时，扫描无线局域网热点是由移动终端的主处理单元如中央处理器(CPU)进行的，因此每次需要扫描无线局域网热点时都需要唤醒主处理单元。Although the wireless LAN background scanning can improve the user experience of using the wireless local area network in the mobile terminal, when the wireless local area network background scanning is turned on, the scanning wireless local area network hot spot is performed by the mobile terminal's main processing unit such as a central processing unit (CPU), so each The main processing unit needs to be woken up when scanning the wireless LAN hotspot.
发明内容Summary of the invention
由于移动终端在以较高速度移动时，在很短时间内就会移出无线局域网热点的覆盖范围，此时的移动终端一般是通过无线通信的数据业务服务而不会通过连接到无线局域网访问网络，因此，当移动终端以较高速度移动时，移动终端的主处理单元进行无线局域网后台扫描是没有必要的。主处理单元是移动终端中功耗最大的器件之一，当移动终端以较高速度移动时无线局域网后台扫描会较大地增加移动终端的功耗，从而降低移动终端的电池的利用率。
Since the mobile terminal moves out at a higher speed, the coverage of the wireless local area network hotspot is removed in a short time, and the mobile terminal at this time generally uses the data communication service of wireless communication without accessing the network through the connection to the wireless local area network. Therefore, when the mobile terminal moves at a higher speed, it is not necessary for the main processing unit of the mobile terminal to perform wireless LAN background scanning. The main processing unit is one of the most power-consuming devices in the mobile terminal. When the mobile terminal moves at a higher speed, the wireless local area network background scanning greatly increases the power consumption of the mobile terminal, thereby reducing the battery utilization rate of the mobile terminal.
本发明实施例提供了一种控制无线局域网后台扫描的方法和装置，能够避免当移动终端以较高速度移动时移动终端的主处理单元不必要进行的无线局域网后台扫描，从而能够节省移动终端的功耗。The embodiment of the invention provides a method and a device for controlling the background scanning of the wireless local area network, which can avoid the wireless local area network background scanning that the main processing unit of the mobile terminal does not need to perform when the mobile terminal moves at a higher speed, thereby saving the mobile terminal.

本发明的较佳实施方式Preferred embodiment of the invention
下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机***中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，
可以以不同于此处的顺序执行所示出或描述的步骤。The steps illustrated in the flowchart of the figures may be executed in a computer system such as a set of computer executable instructions. And, although the logical order is shown in the flowchart, in some cases,
The steps shown or described may be performed in an order different than that herein.
图1为本发明实施例的移动终端中控制无线局域网后台扫描的流程图，如图1所示，包括：FIG. 1 is a flowchart of controlling a background scanning of a wireless local area network in a mobile terminal according to an embodiment of the present invention, as shown in FIG. 1 , including:
步骤101：当移动终端处于黑屏状态时，移动终端的定位单元按照预先设置的比较周期确定检测到的两个或两个以上移动速度是否均大于预先设置的速度阈值。Step 101: When the mobile terminal is in a black screen state, the positioning unit of the mobile terminal determines whether the detected two or more moving speeds are greater than a preset speed threshold according to a preset comparison period.
本领域技术人员熟知的是，当定位单元如GPS芯片工作时，其定期如每0.1秒钟检测移动终端的移动速度。本领域技术人员容易理解的是，可以通过配置定位单元的相关参数使得定位单元实现本步骤。It is well known to those skilled in the art that when a positioning unit, such as a GPS chip, operates, it periodically detects the moving speed of the mobile terminal every 0.1 second. It will be readily understood by those skilled in the art that the positioning unit can implement the present step by configuring relevant parameters of the positioning unit.
本步骤中，比较周期可以预先设置为1秒、2秒或5秒，速度阈值可以预先设置为1米/秒、2米/秒，5米/秒。In this step, the comparison period may be preset to 1 second, 2 seconds, or 5 seconds, and the speed threshold may be preset to 1 meter/second, 2 meters/second, and 5 meters/second.
需要说明的是，当移动终端处于亮屏状态(例如，用户操作移动终端)时，预先设置的比较周期和速度阈值可以通过外部指令进行重新设置，其中，外部指令可以通过本领域技术人员公知的人机交互技术进行获取。It should be noted that when the mobile terminal is in a bright screen state (for example, the user operates the mobile terminal), the preset comparison period and the speed threshold may be reset by an external command, wherein the external command may be known by a person skilled in the art. Human-computer interaction technology is acquired.
其中，确定移动终端处于黑屏状态或者亮屏状态的技术是本领域技术人员公知的。Among them, a technique for determining that the mobile terminal is in a black screen state or a bright screen state is well known to those skilled in the art.
步骤102：如果确定结果是均大于预先设置的速度阈值，移动终端的主处理单元停止无线局域网后台扫描。Step 102: If the determined result is greater than a preset speed threshold, the main processing unit of the mobile terminal stops the wireless local area network background scanning.
其中，主处理单元停止无线局域网后台扫描的具体实现，为本领域技术人员的惯用技术手段，不用于限制本发明的保护范围，此处不再赘述。The specific processing unit of the main processing unit stops the WLAN background scanning, which is a common technical means for those skilled in the art, and is not used to limit the protection scope of the present invention, and details are not described herein again.
如果移动速度均大于速度阈值，说明移动终端以较高速度移动，则停止无线局域网后台扫描，这样避免了移动终端的主处理单元不必要进行的无线局域网后台扫描，也就是说，避免了主处理单元频繁唤醒。If the moving speed is greater than the speed threshold, indicating that the mobile terminal moves at a higher speed, the wireless local area network background scanning is stopped, thereby avoiding unnecessary wireless LAN background scanning by the main processing unit of the mobile terminal, that is, avoiding main processing. The unit wakes up frequently.
需要说明的是，当前比较周期结束即下一个比较周期开始，且确定结果是均大于预先设置的速度阈值时，定位单元发送确定结果给主处理单元，触发其停止无线局域网后台扫描。It should be noted that, when the current comparison period ends, that is, the next comparison period starts, and the determination result is greater than the preset speed threshold, the positioning unit sends the determination result to the main processing unit, and triggers it to stop the wireless local area network background scanning.
可选地，如果确定结果是均小于或等于速度阈值，本发明实施例的方法还包括：主处理单元开启无线局域网后台扫描。
Optionally, if the determined result is less than or equal to the speed threshold, the method of the embodiment of the present invention further includes: the main processing unit turns on the wireless local area network background scanning.
其中，主处理单元开启无线局域网后台扫描的具体实现，为本领域技术人员的惯用技术手段，不用于限制本发明的保护范围，此处不再赘述。The specific implementation of the WLAN back-end scanning by the main processing unit is a common technical means for those skilled in the art, and is not used to limit the protection scope of the present invention, and details are not described herein again.
如果移动速度均小于或等于速度阈值，说明移动终端以较低速度移动或者静止，则开启无线局域网后台扫描，这样当用户想操作移动终端通过无线局域网获取信息，且移动终端能够扫描到之前鉴权的无线局域网热点时，移动终端已经提前自动连接到该无线局域网热点，使得用户直接可以通过无线局域网获取信息而不用等待移动终端连接到无线局域网热点，从而改善了移动终端中使用无线局域网的用户体验。If the moving speed is less than or equal to the speed threshold, indicating that the mobile terminal moves at a lower speed or is stationary, the wireless local area network background scanning is turned on, so that when the user wants to operate the mobile terminal to obtain information through the wireless local area network, and the mobile terminal can scan the previous authentication. When the WLAN hotspot is hot, the mobile terminal has automatically connected to the WLAN hotspot in advance, so that the user can directly obtain information through the WLAN without waiting for the mobile terminal to connect to the WLAN hotspot, thereby improving the user experience of using the WLAN in the mobile terminal. .
需要说明的是，当前检测周期结束即下一个检测周期开始，且确定结果是均小于或等于速度阈值时，定位单元发送确定结果给主处理单元，触发其开启无线局域网后台扫描。It should be noted that, when the current detection period ends, that is, the next detection period starts, and the determination result is less than or equal to the speed threshold, the positioning unit sends the determination result to the main processing unit to trigger the wireless local area network background scanning.
综上所述，当开启无线局域网后台扫描时，主处理单元单元定期唤醒，而本发明实施例的方法在移动终端以较高速度移动时，一方面，主处理单元唤醒一次，另一方面，定位单元的功耗明显小于当开启无线局域网后台扫描时定期唤醒主处理单元时主处理单元的功耗。因此，本发明实施例的方法明显降低了移动终端以较高速度移动时主处理单元的唤醒次数，从而较好地降低了移动终端的功耗，提高了移动终端的电池的利用率。In summary, when the WLAN background scan is enabled, the main processing unit unit wakes up periodically, and the method of the embodiment of the present invention, when the mobile terminal moves at a higher speed, on the one hand, the main processing unit wakes up once, on the other hand, The power consumption of the positioning unit is significantly less than the power consumption of the main processing unit when the main processing unit is periodically woken up when the wireless LAN background scanning is turned on. Therefore, the method of the embodiment of the invention significantly reduces the number of wakeups of the main processing unit when the mobile terminal moves at a higher speed, thereby better reducing the power consumption of the mobile terminal and improving the utilization rate of the battery of the mobile terminal.
可选地，当移动终端处于亮屏状态时，本发明实施例的方法还包括：主处理单元开启无线局域网后台扫描。这样实现了在该情况下，无线局域网后台扫描始终开启，保证了用户能够始终通过连接到无线局域获取信息。Optionally, when the mobile terminal is in a bright screen state, the method of the embodiment of the present invention further includes: the main processing unit turns on the wireless local area network background scanning. This achieves that in this case, the wireless LAN background scan is always on, ensuring that the user can always obtain information by connecting to the wireless local area.
