detailed description

In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to related drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

An embodiment of the present application provides a wireless fidelity Wi-Fi access method, which is applied to a client. As shown in FIG. 1, the method includes:

S101. Receive a wireless local area network opening command and search for alternative networks in the wireless local area network;

The electronic device can monitor the receiving behavior of the application's wireless LAN open command through the built-in monitoring function (listen ()). Taking the electronic device of the Android system as an example, the system can be created at the system framework layer (native / framework layer) The monitoring module of the same level, through the monitoring module, monitors the command line of the application's wireless local area network, or independently creates a monitoring process and monitors whether the wireless local area network is turned on through a message transmission mechanism. For example, you can set up a monitoring module at the framework layer and run it in the system service program (system_server). Because the monitoring module is set up at the system-level service framework layer, you can easily interact with other system services without worrying about system calls. Permissions issue. In addition, you can also create an independent monitoring process, set up and call a separate monitoring function in this process, can be set to start automatically after booting, and monitor the receiving command line and query command line of any other application in real time, specifically , It can capture the data information and open status identification of the currently called wireless local area network interface in real time to determine whether the wireless local area network opening command is currently received. It can be independently developed without coupling with the system, which is convenient for subsequent development and upgrade.

Wi-Fi power consumption of electronic products is relatively large. Therefore, the upper-layer application sets switches to turn the Wi-Fi function on and off. When the user clicks on the mobile phone to open Wi-Fi, the Wi-Fi module is powered on and runs, and of course the Wi-Fi driver will be loaded accordingly. Use the listen function (listen ()) to monitor the wireless LAN opening command, which means that the Wi-Fi function is turned on, and the electronic product displays that the nearby Wi-Fi hotspot is searched. This search process is scanning. Use the scan to find the wireless network, and then join the alternative network. In the process of accessing the network, the access point (Access Point, AP) sends a beacon frame to the mobile terminal. The beacon frame can contain the network's Service Set Identifier (SSID), and the user can choose himself according to the SSID A wireless LAN that can be joined. The SSID is actually the parameter that the Access Point responds to when the workstation scans, as well as other network parameters, including the Media Access Control (MAC) address, signal strength, encryption, and authentication method of the access point Wait. It should be pointed out that during the scan network detection of the Wi-Fi alternative network, if it is detected that the Internet is still not available within the preset time, other alternative network detection is triggered. Among them, the preset time is set according to the Wi-Fi optional network scanning detection process. The specific time can be set by the engineer according to the hardware parameters or software algorithms, and will not be described here.

S102. Select and confirm an access network in the alternative network, and select a preset configuration Internet Protocol (Internet Protocol, IP) method for the access network to configure an IP address of the access network, where, The preset IP configuration modes include: static IP configuration mode, dynamic IP configuration mode, and Point-to-Point Protocol over Ethernet (PPPoE) configuration mode based on Ethernet. It should be noted that the selection method of configuring the Internet protocol IP mode may be that the preset configuration IP mode is automatically selected according to the priority policy of the IP configuration mode. The priority policy may be set as follows: the dynamic IP configuration mode has a higher priority than the PPPoE configuration IP mode; the PPPoE configuration IP mode has a higher priority than the static IP configuration mode. Wherein, the modification authority of the priority policy may be provided by the user. The user can modify the priority strategy according to personal needs.

In a wireless local area network, electronic devices communicate based on the wireless fidelity (WIreless-FIdelity, Wi-Fi) protocol. During the process of accessing the network, the access point (Access Point, AP) sends a beacon frame to the mobile terminal. The target frame can include the service set identifier (SSID) of the network, and the user can select the wireless local area network that he can join according to the SSID.

Static IP configuration is a static IP address set by the user to the electronic device according to the characteristics of the router's own IP address. This address will not change when the device is restarted or the router is restarted. Dynamic IP configuration is automatically assigned by the Dynamic Host Configuration Protocol (DHCP) server. DHCP is the network protocol of the local area network and uses the UDP protocol to work. The DHCP protocol allows the server to dynamically assign IP addresses and configuration information to clients. The DHCP protocol supports a C / S structure, which is mainly divided into a client and a server. The IP address assigned by the DHCP server is affected by the lease of the address and the status of the device. After the lease expires, the IP address will be recovered by the DHCP server. Restarting the device, restarting the router, or reconnecting to the network will cause the DHCP server to reassign IP. address.

The PPPoE configuration method has a high cost performance, and it is widely used in a series of applications including community networking construction. The current popular broadband access methods such as Asymmetric Digital Subscriber Line (ADSL) use PPPoE protocol . PPPoE uses Ethernet to form a large number of hosts into a network, connect to the Internet through a remote access device, and implement control and billing functions for each host accessed. Most computers that access the Internet through ADSL are connected to the Internet through an Ethernet card (Ethernet). The same TCP / IP method is also used, and no new protocol is added. The dial-up Internet access of the modem uses Point-to-Point Protocol (PPP), which has the functions of user authentication and notification of IP address. The PPP Over Ethernet (PPPoE) protocol is a technology for relaying PPP frame information in an Ethernet network, and is particularly suitable for ADSL and other methods.

The priority strategy of the IP configuration mode can be automatically selected, mainly involving the transition from high priority to low priority, for example, including: two cases,

First, the current IP configuration method is automatically selected as the dynamic IP configuration method, but if the DHCP server cannot allocate dynamic IP, it automatically switches to the PPPoE configuration IP method. The specific steps are as follows: detect that the IP configuration mode is automatically selected as the dynamic IP configuration mode; according to the dynamic host configuration DHCP protocol, detect that the client's physical network interface connection end does not have a DHCP server, then directly switch the client's IP configuration mode to all The PPPoE method is described. Or, detect that the IP configuration mode is automatically selected as the dynamic IP configuration mode; according to the dynamic host configuration DHCP protocol, detect that the DHCP server exists at the connection end of the physical network interface, and then detect whether the physical network interface and the DHCP server A DHCP session is established, and it is found that the physical network interface has not established a call with the DHCP server; then the client's IP configuration mode is switched to the PPPoE mode.

Second, the current IP configuration mode is automatically selected as the PPPoE configuration mode, but the PPPoE server cannot automatically assign a dynamic IP and then automatically switches to the static configuration IP mode. The specific steps are as follows: detecting that the IP configuration mode is automatically selected as the PPPoE mode; according to the PPPOE protocol, detecting that there is no PPPoE server on the client's physical network interface connection end, and switching the client's IP configuration mode to the static IP configuration mode. Or, detect that the IP configuration mode is automatically selected as the PPPoE mode; according to the PPPOE protocol, detect that there is a PPPoE server at the connection end of the physical network interface, then detect whether the physical network interface establishes a PPPoE session with the PPPoE server; if not established During a call, switch the client's IP configuration mode to the static IP configuration mode.

It should be noted that if the priority policy is a priority policy set by the user, for example, the priority of the PPPoE configuration IP method is higher than that of the dynamic IP configuration method or the dynamic IP configuration method The level is higher than the dynamic configuration IP mode. The automatic switching detection method of the IP configuration mode is the same, for example: the PPPoE configuration IP mode has a higher priority than the dynamic IP configuration mode, then the electronic equipment is automatically selected as the PPPoE mode; according to the PPPOE protocol, the detection There is no PPPoE server at the connection end of the physical network interface of the client, and the IP configuration mode of the client is switched to the dynamic IP configuration mode. Or, detect that the IP configuration mode is automatically selected as the PPPoE mode; according to the PPPOE protocol, detect that there is a PPPoE server at the connection end of the physical network interface, then detect whether the physical network interface establishes a PPPoE session with the PPPoE server; if not established During a call, switch the IP configuration mode of the client to the dynamic IP configuration mode. Setting other priority policies, the switch detection method of the IP configuration method is similar, and will not be described here.

S103. Detect that the IP configuration mode is the PPPoE configuration mode, and pop up a user account information input box to obtain the account information input by the user;

The method of detecting the configuration IP method can monitor the configuration IP interface occupancy information of the application through the built-in monitoring function of the electronic device. Taking the electronic device of the Android system as an example, a system-level can be created at the system framework layer (native / framework layer) The monitoring module monitors the configuration IP mode of the application through the monitoring module, or independently creates a monitoring process and monitors the configuration IP mode of the application through the message transmission mechanism. For example, you can set up a monitoring module at the framework layer and run it in the system service program (system_server). Because the monitoring module is set up at the system-level service framework layer, you can easily interact with other system services without worrying about system calls. Permissions issue. If the IP mode is configured as a PPPoE configuration mode, that is, the condition that the user's account information input box is triggered to display is met, the electronic device screen displays the account information input box, and the user fills in the legal account information to establish a connection.

The user confirms the alternative network by entering the wireless network selection information. The user sets the IP configuration mode for the alternative network. If the IP configuration mode is the PPPoE configuration mode, a user account information input box pops up, and the user establishes a network connection by entering the account information . Among them, the input information includes, legal user name information and password information matching the user name.

S104. Perform PPPoE authentication according to the input account information, and establish a connection with the access network. The account information input box is also used to back up the account information using a cloud server. The specific method includes: storing the account information and uploading it to the cloud server, and receiving a response from the cloud server that the account information has been successfully saved; if the client is reset or replaced, according to the input The user name sends a request to the server to obtain the password corresponding to the user name; receives the password corresponding to the user name issued by the cloud server, and fills in the password input box to enable PPPoE authentication of the user's account information .

The PPPoE method for configuring the IP connection to the network includes: the client and the access concentrator (Access) acquire the Ethernet physical address of the peer, and the client and the access concentrator share a unique session ID; The client sends a Discovery Phase Initialization (PPPoE Active Discovery, Initiation, PADI) broadcast message to the preset broadcast domain to apply for services from the AC in the preset broadcast domain, where the preset broadcast area may be within the cell. Or any value within the range of 1m-1000m, including the range; preset one or more AC Discovery Phase Reply (PPPoEActive Discovery, Offer, PADO) messages in the broadcast domain, in response to which the client can be served; the client host is based on the preset Need to select an AC and send it a discovery phase request (PPPoE Active Discovery Request, PADR) message to request services from the AC, where the preset requirements of the client host can be signal strength, distance information, or security information; The AC sends a session commitment (PPPoEActive Discovery Session, Configuration, PADS) message to the client to announce the provision of services to the client and share a unique session ID with the client. The client and the access concentrator establish a dial-up connection through the session ID and perform point-to-point network layer data packet transmission; the PPP negotiation at the PPPoE session negotiation stage is the same as the ordinary PPP negotiation; the client connects Enter the network and interact with data. The client or the access concentrator, when the client or server needs to terminate the session, can send such a PADT message. Both parties to the session can send a termination message (PPPoEActiveDiscoveryTerminate, PADT) as required. Disconnect the PPPoE connection between the two sides of the session.

The method provided in this embodiment of the present application may further include:

S105. If the dial-up connection established in the PPPoE mode is abnormally offline, and the abnormal offline belongs to the preset abnormal offline entry, the client sends a request to the server to authenticate the identity of the PPPoE client. If the server authentication is successful, the dial-up connection is restored. Specifically, it may include: acquiring data information of abnormal log-off; querying the abnormal log-off identifier of the data information, confirming that the abnormal log-off identifier is in the preset abnormal log-off entry, wherein the preset abnormal log-off table The item may include a router restart, a short power outage of the device, link flapping, hardware failure, and client restart, etc .; if it belongs to any of the above table items, it is sent to the server to request authentication of the client identity Authentication message; receiving the identity authentication success response returned by the server, and recovering the abnormal offline dial-up connection.

In the application of the existing network based on the Point-to-Point Protocol over Ethernet (PPPoE), usually the client and the Broadband Remote Access Server (BRAS) device are interconnected through a Layer 2 switch. When the access port link of the BRAS device fluctuates or the hardware fails, the client will be abnormally offline. The public network address of the BRAS device in the client still exists. The client can still continue to access the public network, but the BRAS device should The user entry of the access port corresponding to the client will be automatically cleared, and the BRAS device cannot send PADT messages to the client, so the client cannot perceive the failure. In this case, the client can only rely on its own periodic keepalive detection mechanism to sense that it has been abnormally offline. Obtain the abnormal offline data information through the client; and query the abnormal offline identifier of the data information to confirm that the abnormal offline identifier is in the preset abnormal offline entry, then send to the server for An authentication message requesting authentication of the identity of the client; when receiving the identity authentication success response returned by the server, the abnormal offline dial-up connection is restored. The network recovery connection method in other situations in the preset abnormal offline entry is similar to the link recovery and hardware failure network recovery connection method. I won't repeat them here.

For example, you can set up a monitoring module at the framework layer and run it in the system service program (system_server). Because the monitoring module is set up at the system-level service framework layer, you can easily interact with other system services without worrying about system calls. Permissions issue. In addition, you can also create an independent monitoring process, set up and call a separate monitoring function in this process, can be set to start automatically after booting, and monitor the receiving command line and query command line of any other application in real time, specifically , It can capture the data information and open status identification of the currently called wireless local area network interface in real time to determine whether the wireless local area network opening command is currently received. It can be independently developed without coupling with the system, which is convenient for subsequent development and upgrade.
