However, the following problems exist: the AP cannot be connected to the Internet or the networking speed is slow. In this case, the user cannot manually detect the abnormal situation and the user cannot perform normal network access. Go to other network interfaces. The complexity of the use of the WLAN AP is increased, which has a large negative impact on the normal use of the user and the user experience.

请参阅图2，图2为本发明一个实施例的无线网络接入点的连接方法流程图，主要描述了多个无线接入点(以下称WLAN AP)状态检测以及智能化切换的主要过程，以下按照标识对流程中的步骤进行较详细的描述与说明：Referring to FIG. 2, FIG. 2 is a flowchart of a method for connecting a wireless network access point according to an embodiment of the present invention, and mainly describes a main process of state detection and intelligent handover of multiple wireless access points (hereinafter referred to as WLAN APs). The following is a detailed description and description of the steps in the process according to the identification:
步骤101，读取WLAN AP列表；所述WLAN AP列表是预先设置到终端或者用户手动添加生成，预置的WLAN AP列表在出厂前保持在终端设备的数据库里；开机后，用户也可以通过WEB UI(网络用户界面)连接设备 后手动添加WLAN AP；Step 101: Read the WLAN AP list; the WLAN AP list is preset to the terminal or manually added by the user, and the preset WLAN AP list is kept in the database of the terminal device before leaving the factory; after booting, the user can also pass the WEB. UI (network user interface) connection device Manually add a WLAN AP;
步骤102，判断当前WLAN AP列表是否为空；如果为空则执行步骤108，如果不为空则执行步骤103； Step 102, it is determined whether the current WLAN AP list is empty; if it is empty, step 108 is performed, if not empty, step 103 is performed;
步骤103，开启设备的WLAN功能，扫描周围的WLAN AP；Step 103: Enable the WLAN function of the device, and scan the surrounding WLAN AP.
步骤104，检测预先设置的WLAN AP的信号强度是否可以连接；如果当前没有可连接的WLAN AP，则执行步骤108，如果当前有可连接的WLAN AP，则执行步骤105； Step 104, detecting whether the signal strength of the preset WLAN AP can be connected; if there is currently no WLAN AP that can be connected, step 108 is performed, if there is currently a connectable WLAN AP, step 105 is performed;
步骤105，连接WLAN AP； Step 105, connecting to the WLAN AP;
其中，根据预先设置的WLAN AP列表的优先级进行连接WLAN AP；如果存在多个AP(接入点)，则选择信号强度最强的AP连接。The WLAN AP is connected according to the priority of the preset WLAN AP list; if there are multiple APs (access points), the AP with the strongest signal strength is selected.
步骤106，判断当前WLAN AP连接是否成功；如果Wi-Fi连接失败或获取IP失败，则执行步骤107；如果Wi-Fi连接成功且获取IP成功，则执行步骤109； Step 106, it is determined whether the current WLAN AP connection is successful; if the Wi-Fi connection fails or the IP acquisition fails, step 107 is performed; if the Wi-Fi connection is successful and the IP acquisition is successful, step 109 is performed;
步骤107：切换其他可连接的WLAN AP，如果没有则执行步骤108，如果有，则执行步骤105；Step 107: Switching other connectable WLAN APs, if not, executing step 108, if yes, executing step 105;
步骤108，当前WLAN AP列表为空或没有可连接的WLAN AP时，则切换到其他网络，如SIM卡的2G、3G或4G上网或者有线网络接口；Step 108: If the current WLAN AP list is empty or has no connectable WLAN AP, switch to another network, such as a 2G, 3G or 4G Internet access or a wired network interface of the SIM card;
步骤109，检测当前WLAN AP的网络连通性状态，通过连通性检测技术判断网络是否可达，如果否，则执行步骤107；如果可达，执行步骤110； Step 109, detecting the current network connectivity state of the WLAN AP, determining whether the network is reachable by the connectivity detection technology, if not, executing step 107; if yes, executing step 110;
其中，请结合参照图5，步骤109可采用ping的方法流程、trace route命令检测或者直接访问页面等方式检测当前AP的网络连通性状态。以下举例采用ping的方法流程：For example, referring to FIG. 5, step 109 can detect the network connectivity status of the current AP by using a ping method flow, a trace route command, or a direct access page. The following example uses the ping method flow:
连通性检测技术可以通过设备向外网服务器发送ping报文来检测当前网络是否连通可达。外网服务器是部署在互联网上的一服务器，例如：Google提供的免费DNS服务器，这是一组快速，安全并且完全免费的DNS解析服务器(主服务器IP地址为8.8.8.8，备用服务器IP地址为8.8.4.4)。通讯采用一问一答的方式，由设备主动发起，当外网服务器收到终端所发送的ping请求报文后，构造相应的ping回应报文并发送，设备通过解析ping回应报 文判断网络是否连通，其中，通过预置响应时间阈值对比ping报文响应时间判断当前网络速度。The connectivity detection technology can send ping packets to the external network server to check whether the current network is reachable. The external server is a server deployed on the Internet, for example: a free DNS server provided by Google. This is a fast, secure and completely free DNS resolution server (the primary server IP address is 8.8.8.8, and the standby server IP address is 8.8.4.4). The communication is initiated by the device. When the external network server receives the ping request packet sent by the terminal, it constructs a corresponding ping response packet and sends it. The device responds by pinging the ping response. The text determines whether the network is connected, wherein the current network speed is determined by comparing the preset response time threshold with the ping message response time.
步骤110，实时检测当前AP的网络连接性能参数；其中，可通过多种技术手段检测实时网络性能参数；同时对当前连接网络接口的数据进行分析，检测是否存在对实时性要求很高的通讯存在；如果满足性能要求，则执行步骤111；如果无法满足性能要求，则执行步骤107；Step 110: Real-time detection of network connection performance parameters of the current AP; wherein, real-time network performance parameters can be detected by various technical means; and data of the currently connected network interface is analyzed to detect whether there is communication with high real-time requirements. If the performance requirements are met, step 111 is performed; if the performance requirements are not met, step 107 is performed;
步骤111，保持当前BSSID连接，返回步骤110。In step 111, the current BSSID connection is maintained, and the process returns to step 110.
其中，本实施例中网络性能通过计算定长时间内端口单向的数据包总流量获得速率。速率常用统计单位是比特/秒(bps)，1Mbps＝1024kbps，1kbps＝1024bps。其中，分别计算WLAN侧发送或接收报文接口的流量(TX:transmit发送的端口流量；RX:receive接收到的端口流量)，基于流量，根据算式：流量差/时间差获取当前速率。The network performance in this embodiment is obtained by calculating the total traffic rate of the unidirectional data packet of the port for a long time. The common statistical unit of rate is bit/second (bps), 1Mbps=1024kbps, and 1kbps=1024bps. The traffic of the interface that sends or receives the packet on the WLAN side (TX: the port traffic sent by the transmit; RX: the received port traffic) is calculated based on the traffic, and the current rate is obtained according to the formula: the traffic difference/time difference.
例如，可以通过FTP(File Transfer Protocol，文件传输协议)或HTTP(HyperText Transfer Protocol，超文本传输协议)的方式进行下载速率检测，获得连接当前AP的下载速率对比信息。为了能够较准确的获得速率信息，可以采用启动多个线程同时进行一定时间下载的方式；另外在不同接口的情况下，可以选择不同的测速服务以保证测速数据的准确性。由于FTP或HTTP协议属于标准协议，因此此处不做更详细的描述。For example, the download rate detection can be performed by means of FTP (File Transfer Protocol) or HTTP (HyperText Transfer Protocol) to obtain the download rate comparison information of the current AP. In order to obtain rate information more accurately, a method of starting multiple threads simultaneously for a certain time of downloading may be adopted; in addition, in different interface situations, different speed measuring services may be selected to ensure the accuracy of the speed measuring data. Since the FTP or HTTP protocol is a standard protocol, it will not be described in more detail here.
由于存在很多对实时性要求很高的应用，如电话会议、VOIP(Voice over Internet Protocol，网络电话)等，为保证用户正常使用，在检测到此类应用时不应该进行AP的切换，等待这些业务停止之后方再进行切换。首先需要形成此类应用的报文特征样本库，包括协议的端口、协议报文中的特征信息等，为了后续扩展，此样本库可以支持不断添加新协议的样本。出于性能考虑，检测的实现主要借助旁路方式的报文监听技术，如tcpdump、原始套接字等，对流经MIFI、CPE的所有网络报文进行旁路式的采集并分析，判断报文特征是否与特征样本库匹配，如若匹配则认为当前存在对实时性要求较高的应用。Because there are many applications that require high real-time performance, such as teleconferencing, VOIP (Voice over Internet Protocol), etc., in order to ensure the normal use of users, APs should not be switched when detecting such applications. Wait for these. Switch after the business is stopped. First, it is necessary to form a message sample database of such applications, including the protocol port, the feature information in the protocol message, etc., for subsequent expansion, the sample library can support the continuous addition of new protocol samples. For performance reasons, the detection is implemented by bypassing the packet monitoring technology, such as tcpdump and original sockets. Bypassing and analyzing all network packets flowing through the MIFI and CPE, and determining the packet. Whether the feature matches the feature sample library, if it matches, it is considered that there is currently an application with high real-time requirements.
