A mobile terminal (station STA) establishes a connection with a wireless access point (Access Point, AP) by using a wireless fidelity (Wireless Fidelity, Wi-Fi) technology to access a wireless local area network. Specifically, the mobile terminal has a built-in Wi-Fi module. In order to access the wireless local area network, the mobile terminal first needs to scan to find out whether there is an available wireless local area network nearby. There are two scanning methods: active scanning and passive scanning. Among them, the mobile terminal must first obtain the relevant information of the available access points through the scanning mechanism. No matter where the user is, such as shopping, going to work, traveling, etc., the same scanning method is used to obtain the available access points. The scanning process has problems of high power consumption and short battery life.

The working environment involves various application scenarios, for example, including Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), Global System for Mobile Communication (GSM), and WLAN, etc. . As a non-limiting example, the following description refers to a WLAN communication system, but such teachings are equally applicable to other types of systems. As shown in FIG. 1 , its working environment involves a mobile terminal 100, a cloud server 101, a base station 102, and a wireless access device (eg, a wireless access point, AP) 103, and the mobile terminal 100 and the base station 102 can communicate with each other , each base station 102 can communicate with the cloud server 101, the mobile terminal 100 can also communicate with the cloud server 101 through a related network other than the base station 102, and the mobile terminal 100 can also communicate with the wireless access device 103 to establish a wireless network connect.

如图2所示，在一个实施例中，提供了一种移动终端无线局域网扫描方法，应用于具备移动通信功能的移动终端，本实施例以该移动终端无线局域网扫描方法应用于上述图1中的工作环境的移动终端100来举例说明。该无线局域网开关的控制方法具体包括如下步骤：As shown in FIG. 2 , in one embodiment, a method for scanning a wireless local area network of a mobile terminal is provided, which is applied to a mobile terminal with a mobile communication function. In this embodiment, the method for scanning a wireless local area network of a mobile terminal is applied to the above-mentioned FIG. 1 The working environment of the mobile terminal 100 is exemplified. The control method of the wireless local area network switch specifically includes the following steps:
步骤202：获取当前可为移动终端提供通信服务的所有基站对应的基站信息，形成当前基站信息列表。Step 202: Acquire base station information corresponding to all base stations that can currently provide communication services for the mobile terminal, and form a current base station information list.
移动终端能够随时通过移动网络与基站进行信息交互，其中，移动网络采用蜂窝布局。当移动终端在扫描周围的无线局域网时，可以扫描到能够为当前移动终端提供通信服务的基站的基站信息，其扫描到的基站的数量可以1个、2个或多个。The mobile terminal can exchange information with the base station through the mobile network at any time, wherein the mobile network adopts a cellular layout. When the mobile terminal scans the surrounding wireless local area network, it can scan the base station information of the base stations that can provide communication services for the current mobile terminal, and the number of the scanned base stations can be one, two or more.
具体地，基站信息通常包含有移动国家代码(Mobile country code，MCC)、移动网络号码(Mobile Network Code，MNC)、位置区域码(location area code，LAC)、基站编号(Cell Identity，CID)以及基站信号强度(Base Station Signal Strength，BSSS)等。对于每一个基站，其位置区域码和基站编号都是唯一的，因此通过获取基站信息可以唯一识别基站，并且能够确定基站的所属区域，以实现区域的识别。当移动终端的所处位置固定不变，且基站发射出的基站信息能够覆盖当前移动终端所处的位置区域时，则认为该基站可以理解为能够为移动终端提供通信服务的基站。将获取的当前可为移动终端提供通信服务的所有基站对应的基站信息按照基站编号或位置区域码形成当前基站信息列表。Specifically, the base station information usually includes a mobile country code (Mobile country code, MCC), a mobile network code (Mobile Network Code, MNC), a location area code (location area code, LAC), a base station number (Cell Identity, CID) and Base Station Signal Strength (BSSS), etc. For each base station, its location area code and base station number are unique, so by acquiring base station information, the base station can be uniquely identified, and the area to which the base station belongs can be determined to realize the identification of the area. When the location of the mobile terminal is fixed and the base station information transmitted by the base station can cover the current location area of the mobile terminal, it is considered that the base station can be understood as a base station that can provide communication services for the mobile terminal. The acquired base station information corresponding to all base stations that can currently provide communication services for the mobile terminal is formed into a current base station information list according to the base station number or location area code.
可选的，移动终端还可以将获取的基站信息还可以被发送至云服务器，由云服务器根据基站信息对基站进行识别，再由云服务器返回识别结果给移动终端，本实施例对此不作限定。Optionally, the mobile terminal may also send the acquired base station information to a cloud server, and the cloud server identifies the base station according to the base station information, and then the cloud server returns the identification result to the mobile terminal, which is not limited in this embodiment. .
步骤204：调用预设基站数据库，所述预设基站数据库用于存储至少一个可用无线接入设备对应的所有目标基站的基站信息。Step 204: Invoke a preset base station database, where the preset base station database is used to store base station information of all target base stations corresponding to at least one available wireless access device.
预设基站数据库中存储有至少一个可用无线接入设备对应的所有目标基站的基站信息。其中，无线接入设备可以为无线接入点AP，可用无线接入设备为移动终端已经成功访问过该无线接入设备的无线局域网，例如，家用可用AP、工作单位可用AP、经常访问的可用AP或其他公共区域可用AP等等。The base station information of all target base stations corresponding to at least one available wireless access device is stored in the preset base station database. The wireless access device may be a wireless access point AP, and the available wireless access device is a wireless local area network where the mobile terminal has successfully accessed the wireless access device. AP or other public area available AP and so on.
当移动终端与一个可用无线接入设备进行通信时，移动终端会自动记录当前周围能够为移动终端提供通信服务的所有目标基站的基站信息，并将这些目标基站的基站信息按照预设存储机制存储在预设基站数据库。When the mobile terminal communicates with an available wireless access device, the mobile terminal will automatically record the base station information of all target base stations around it that can provide communication services for the mobile terminal, and store the base station information of these target base stations according to the preset storage mechanism in the preset base station database.
步骤206：当所述当前基站信息列表中不存在所述预设基站数据库中所述目标基站的基站信息时，启用扫描切换策略，将主动扫描方式切换为被动扫描方式来对无线局域网进行扫描。Step 206 : when the base station information of the target base station in the preset base station database does not exist in the current base station information list, a scanning switching strategy is enabled, and the active scanning mode is switched to the passive scanning mode to scan the wireless local area network.
将获取的基站信息列表中的基站信息与预设基站数据库中所述目标基站的基站信息进行对比，当发现当前基站信息列表中不存在预设基站数据库中所述目标基站的基站信息时，则表明移动终端已经离开了任意可用无线接入设备的无线局域网的覆盖区域，例如出差、旅游、在上下班的路上等等，当移动终端已经离开了任意可用无线接入设备的无线局域网的覆盖区域时，启动扫描切换策略，将主动扫描方式切换为被动扫描方式来对无线局域网进行扫描，并不会影响到用户体验，同时还能够节省功耗，提高续航能力，还可以减少辐射，可以避免采用主动扫描无形中增加移动终端的功耗，缩短整机的待机时长。Compare the base station information in the acquired base station information list with the base station information of the target base station in the preset base station database, and when it is found that the base station information of the target base station in the preset base station database does not exist in the current base station information list, then Indicates that the mobile terminal has left the coverage area of the wireless local area network of any available wireless access device, such as on a business trip, traveling, on the way to and from get off work, etc., when the mobile terminal has left the coverage area of the wireless local area network of any available wireless access device When the scanning switch strategy is activated, the active scanning mode is switched to the passive scanning mode to scan the wireless LAN, which will not affect the user experience, and can also save power consumption, improve battery life, and reduce radiation. Active scanning virtually increases the power consumption of the mobile terminal and shortens the standby time of the whole machine.
需要说明的是，对于被动扫描方式，移动终端不会主动发送探测请求帧，就是被动的接收无线接入点定期发送的信标帧(Beacon)来发现网络。信标帧包括有无线接入点AP的服务集标识、支持速率、无线接入点的MAC地址、支持的认证方式，加密算法、信标帧发送间隔，使用的信道等信息。例如，无线接入点发送信标帧的默认周期为100ms，即无线接入点每100ms都会广播发送一次信标帧。STA就是通过在其支持的每个信道上侦听信标帧，来获知周围存在的无线网络。It should be noted that, for the passive scanning mode, the mobile terminal does not actively send a probe request frame, but passively receives a beacon frame (Beacon) periodically sent by the wireless access point to discover the network. The beacon frame includes information such as the service set identifier of the wireless access point AP, the supported rate, the MAC address of the wireless access point, the supported authentication method, the encryption algorithm, the beacon frame sending interval, and the channel used. For example, the default period for the wireless access point to send the beacon frame is 100ms, that is, the wireless access point broadcasts and sends the beacon frame every 100ms. The STA learns the surrounding wireless network by listening to the beacon frame on each channel it supports.
需要说明的是，对于主动扫描方式，移动终端会主动在其所支持的信道上依次发送探测信号，用于探测周围存在的无线网络。移动终端发送的探测信号称为探测请求帧(Probe Request)，通过接受探查响应帧(Probe Response)来获取网络信号。探测请求帧又可以分为两类，一类是未指定服务集标识(Service Set Identifier，SSID)，一类是指定服务集标识。若探测请求帧里面未没指定服务集标识，意味着这个探测请求想要获取到周围所有能够获取到的无线网络信号，所有收到这个广播探测请求帧的无线接入点都会回应移动终端。若探测请求帧中指定了服务集标识，意味着移动终端只想找到特定的服务集标识，不需要除指定服务集标识之外的其它无线网络。无线接入点接收探测请求帧后，只有发现探测请求帧中的服务集标识和自己的服务集标识是相同的情况下，才会回应移动终端。It should be noted that, for the active scanning mode, the mobile terminal will actively send detection signals in sequence on the channels supported by the mobile terminal, so as to detect the surrounding wireless networks. The probe signal sent by the mobile terminal is called a probe request frame (Probe Request), and a network signal is obtained by receiving a probe response frame (Probe Response). The probe request frame can be further divided into two categories, one is an unspecified service set identifier (Service Set Identifier, SSID), and the other is a specified service set identifier. If the service set identifier is not specified in the probe request frame, it means that the probe request wants to obtain all available wireless network signals around, and all wireless access points that receive the broadcast probe request frame will respond to the mobile terminal. If the service set ID is specified in the probe request frame, it means that the mobile terminal only wants to find a specific service set ID, and does not need other wireless networks other than the specified service set ID. After the wireless access point receives the probe request frame, it will respond to the mobile terminal only when it finds that the service set ID in the probe request frame is the same as its own service set ID.
上述移动终端无线局域网扫描方法，当所述当前基站信息列表中不存在所述预设基站数据库中所述目标基站的基站信息时，则表明移动终端已经离开了任意可用无线接入设备的无线局域网的覆盖区域，此时，启动扫描切换策略，将主动扫描方式切换为被动扫描方式来对无线局域网进行扫描，能够节省功耗，提高续航能力，可以减少辐射，同时也不会影响用户的体验。In the above-mentioned mobile terminal wireless local area network scanning method, when the base station information of the target base station in the preset base station database does not exist in the current base station information list, it indicates that the mobile terminal has left the wireless local area network of any available wireless access device At this time, the scanning switching strategy is activated, and the active scanning mode is switched to the passive scanning mode to scan the wireless local area network, which can save power consumption, improve battery life, and reduce radiation without affecting the user experience.
如图3所示，在一个实施例中，在所述调用预设基站数据库之前，还包括：As shown in FIG. 3, in one embodiment, before the invoking the preset base station database, the method further includes:
步骤302：当移动终端与无线接入设备连接时，记录可为所述移动终端提供通信服务的所有目标基站对应的基站信息。Step 302: When the mobile terminal is connected to the wireless access device, record base station information corresponding to all target base stations that can provide communication services for the mobile terminal.
当移动终端与可用无线接入设备连接时，移动终端会自动记录当前周围能够为移动终端提供通信服务的所有目标基站的基站信息。其中，目标基站的基站信息包括移动国家代码、移动网络号码、位置区域码、基站编号以及基站信号强度等。对于每一个基站，其位置区域码和基站编号都是唯一的，可以通过对获取的能够为移动终端提供通信服务的所有目标基站对应的基站信息进行分析，进而可以确定基站的所属区域，以实现对地理区域的定位。When the mobile terminal is connected to an available wireless access device, the mobile terminal will automatically record the base station information of all target base stations around it that can provide communication services for the mobile terminal. The base station information of the target base station includes a mobile country code, a mobile network number, a location area code, a base station number, and a signal strength of the base station. For each base station, its location area code and base station number are unique. By analyzing the acquired base station information corresponding to all target base stations that can provide communication services for mobile terminals, the area to which the base station belongs can be determined to achieve Targeting a geographic area.
步骤304：将与所述无线接入设备对应的所有目标基站的基站信息存储在目标基站信息列表中，以形成所述预设基站数据库。Step 304: Store base station information of all target base stations corresponding to the wireless access device in a target base station information list to form the preset base station database.
当移动终端与一个可用无线接入设备连接时，移动终端会自动记录当前周围能够为移动终端提供通信服务的所有目标基站的基站信息。一个可用无线接入设备可以对应多个目标基站的基站信息。也即，可以将该可用无线接入设备对应的所有目标基站的基站信息存储在一个目标基站信息列表中。该目标基站信息列表与该可用无线接入设备一一对应，可以用该可用无线接入设备的名称、唯一标识等信息对该目标基站信息列表进行命名。When the mobile terminal is connected to an available wireless access device, the mobile terminal will automatically record the base station information of all target base stations around it that can provide communication services for the mobile terminal. One available wireless access device may correspond to base station information of multiple target base stations. That is, the base station information of all target base stations corresponding to the available wireless access device may be stored in a target base station information list. The target base station information list is in one-to-one correspondence with the available wireless access devices, and the target base station information list can be named with information such as the name and unique identifier of the available wireless access devices.
当移动终端与分别依次与多个可用无线接入设备进行无线连接时，就可以形成多个与可用无线接入设备一一对应的多个目标基站信息列表，形成的多个目标信息列表就可以形成预设基站数据库。When the mobile terminal is wirelessly connected to multiple available wireless access devices in sequence, multiple target base station information lists corresponding to the available wireless access devices can be formed, and the formed multiple target information lists can be A preset base station database is formed.
需要说明的是，该目标基站信息列表可以以数据包、文件夹等形式存储在预设基站数据库中，但是存储形式并不限于此。It should be noted that the target base station information list may be stored in the preset base station database in the form of a data package, a folder, etc., but the storage form is not limited to this.
如图4所示，在一个实施例中，所述记录可为所述移动终端提供通信服务的所有目标基站对应的基站信息前，还包括：As shown in FIG. 4 , in one embodiment, before the recording of base station information corresponding to all target base stations that can provide communication services for the mobile terminal, the method further includes:
步骤402：获取可为所述移动终端提供通信服务的目标基站的所述基站信号强度信息。Step 402: Acquire the signal strength information of the base station of the target base station that can provide the communication service for the mobile terminal.
在获取可为移动终端提供通信服务的目标基站的基站信息时，也就可以获取基站信息中的基站信号强度信息(Base Station Signal Strength，BSSS)。基站基站信号强度信息为移动终端接收到的由基站发射出的信号强度。When acquiring the base station information of the target base station that can provide the communication service for the mobile terminal, the base station signal strength information (Base Station Signal Strength, BSSS) in the base station information can also be acquired. The base station signal strength information is the signal strength received by the mobile terminal and transmitted by the base station.
步骤404：当所述基站信号强度信息大于预设信号强度阈值时，则记录所述可为移动终端提供通信服务的基站对应的基站信息。Step 404: When the base station signal strength information is greater than a preset signal strength threshold, record the base station information corresponding to the base station that can provide communication services for the mobile terminal.
由于距离、地势等原因，移动终端接入可用无线接入设备时，其此时能够为移动终端提供通信服务的目标基站的基站信息强度信息并不相同，有强有弱。Due to distance, terrain and other reasons, when a mobile terminal accesses an available wireless access device, the base station information strength information of the target base station that can provide communication services for the mobile terminal at this time is not the same.
将获取的基站信号强度信息与预设信号强度阈值进行比较，只将大于该预设信号强度阈值的基站信号强度信息对应的目标基站收录在目标基站信息列表中。而将小于等于该预设信号强度阈值的基站信号强度信息对应的目标基站删除，可以提高预设基站数据库的准确性，进而可以提高对可用无线接入设备无线局域网的覆盖区域的周围区域的辨识度。The acquired base station signal strength information is compared with a preset signal strength threshold, and only target base stations corresponding to base station signal strength information greater than the preset signal strength threshold are included in the target base station information list. Deleting the target base station corresponding to the base station signal strength information less than or equal to the preset signal strength threshold can improve the accuracy of the preset base station database, thereby improving the identification of the surrounding area of the coverage area of the wireless local area network of the available wireless access equipment. Spend.
如图5所示，在一个实施例中，所述形成所述预设基站数据库后，还包括：As shown in FIG. 5 , in an embodiment, after forming the preset base station database, the method further includes:
步骤502：获取所述无线接入设备的无线局域网的覆盖区域。Step 502: Acquire the coverage area of the wireless local area network of the wireless access device.
每个无线接入设备根据自己设备的属性，其能够提供的无线局域网的覆盖区域并不相同，如图6所示，虚线框以内的区域为无线接入设备1的无线局域网的覆盖区域。当移动终端与该无线接入设备1建立通信时，可为移动终端提供通信服务的目标基站有n个，分别为基站1、基站2、...、基站(n-1)、基站n。Each wireless access device can provide different coverage areas of the wireless local area network according to the attributes of its own device. As shown in FIG. When the mobile terminal establishes communication with the wireless access device 1, there are n target base stations that can provide communication services for the mobile terminal, namely base station 1, base station 2, ..., base station (n-1), and base station n.
步骤504：当移动终端在所述覆盖区域移动时，若获取到新的可为所述移动终端提供通信服务的目标基站的基站信息时，更新所述无线接入设备对应的目标基站信息列表。Step 504: When the mobile terminal moves in the coverage area, if new base station information of a target base station that can provide communication services for the mobile terminal is acquired, update the target base station information list corresponding to the wireless access device.
如无线接入设备1的无线局域网的覆盖区域较大，用户手持移动终端在无线接入设备1的无线局域网的覆盖区域内移动时，仍可以保持与该无线接入设备1的通信连接，此时，移动就可以获取新的可为移动终端提供通信服务的目标基站的基站信息，并将获取的新得可为移动终端提供通信服务的目标基站的基站信息更新到无线接入设备对应的目标基站信息列表中，这样就能够实时更新目标基站信息列表，提升用户体验。For example, the coverage area of the wireless local area network of the wireless access device 1 is relatively large, and the user can still maintain the communication connection with the wireless access device 1 when the mobile terminal moves within the coverage area of the wireless local area network of the wireless access device 1. , the mobile can obtain the base station information of the new target base station that can provide communication services for the mobile terminal, and update the newly acquired base station information of the target base station that can provide communication services for the mobile terminal to the target corresponding to the wireless access device. In this way, the target base station information list can be updated in real time, and the user experience can be improved.
结合图6，可以进一步地理解：当当前基站信息列表中不存在预设基站数据库中目标基站的基站信息。也即，当前基站信息列表中不存在预设基站数据库中目标基站的建站信息时，则可以理解为，当前移动终端已经离开了可用无线接入设备的无线局域网的覆盖区域1，或能够为当前移动终端提供通信服务的基站的信号覆盖区域且不再可用无线接入设备的无线局域网的覆盖区域2。此时，可以将移动终端默认的主动扫描方式切换为被动扫描方式，能够节省功耗，提高续航能力，还可以减少辐射，同时，也不会影响到用户体验。With reference to FIG. 6 , it can be further understood that: when there is no base station information of the target base station in the preset base station database in the current base station information list. That is, when there is no site establishment information of the target base station in the preset base station database in the current base station information list, it can be understood that the current mobile terminal has left the coverage area 1 of the wireless local area network of the available wireless access device, or can be the current mobile terminal.

需要说明的是，将可用无线接入设备的无线局域网的覆盖区域1和能够为当前移动终端提供通信服务的基站的信号覆盖区域且不再可用无线接入设备的无线局域网的覆盖区域2称之为主动扫描区域，将除该主动扫描区域的区域称之为被动扫描区域。It should be noted that the coverage area 1 of the wireless local area network where the wireless access device is available and the signal coverage area 2 of the base station that can provide communication services for the current mobile terminal and the wireless local area network where the wireless access device is no longer available are referred to as It is an active scanning area, and the area other than the active scanning area is called a passive scanning area.

The moving speed is inversely proportional to the scanning frequency. . When the wireless local area network is scanned in the passive scanning mode, the scanning frequency is reduced to increase the scanning period, thereby saving power consumption.
