Background

At present, the wifi access mode of the mobile phone device only includes two access modes of Dynamic Host Configuration Protocol (DHCP) and Static IP configuration, for a hotspot needing authentication, after the hotspot is connected, a browser is automatically started to pop up an authentication page, and a user can input an account password in the browser to perform authentication login. However, the static IP configuration allocates a fixed IP address to each computer, so that it is easy for an address allocated by a valid user to be illegally stolen, which not only affects the normal use of the network, but also easily causes loss and potential safety hazard to the valid user because the stolen address often has higher authority. The DHCP server with dynamic IP configuration has no limitation to the access of users, and any computer can obtain correct network configuration through the DHCP server after networking, thereby accessing the network. Illegal users can easily enter the internal network, and potential safety hazards are brought. Especially, when the DHCP server is impersonated, the DHCP server cannot find out the leased IP address, which causes network confusion.

Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

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

s101, receiving a wireless local area network starting command, and searching for an alternative network in the wireless local area network;

the electronic device can monitor the receiving behavior of the wlan open command of the application program through a built-in monitoring function (listen ()), for example, taking the electronic device of the android system as an example, a system-level monitoring module can be created in a system framework layer (native/frame layer), the wlan open command behavior of the application program is monitored through the monitoring module, or a monitoring process is created independently, and whether the wlan is open or not is monitored through a message transmission mechanism. For example, a monitoring module can be set up in a framework layer and run in a system service program (system _ server), and because the monitoring module is set up in a service framework layer of a system level, interaction with other system services can be facilitated without worrying about the authority problem when the system is called. In addition, an independent monitoring process can be created, an independent monitoring function is set and called in the process, the process can be set to be started up automatically, the command receiving line and the command inquiring line of any other application program are monitored in real time, and specifically, data information and an opening state identifier of a currently called wireless local area network interface can be captured in real time, so that whether a wireless local area network opening command is received currently or not is determined, independent development can be achieved, coupling with a system is avoided, and subsequent development and upgrading are facilitated.

The power consumption of the electronic product Wi-Fi is large. Thus, the upper layer application sets a switch for turning on and off the Wi-Fi function. When a user clicks on the mobile phone to open the Wi-Fi, the Wi-Fi module is powered on to run, and certainly, a driver of the Wi-Fi is loaded correspondingly. And monitoring a wireless local area network starting command by using a monitoring function (listen ()), namely indicating that the Wi-Fi function is started, displaying and searching nearby Wi-Fi hotspots by the electronic product, and Scanning (Scanning). Wireless networks are found using the scan and then joined to the alternate network. In the process of accessing the network, an Access Point (AP) sends a beacon frame to a mobile terminal, where the beacon frame may include a Service Set Identifier (SSID) of the network, and a user may select a wireless local area network that the user can join according to the SSID. SSID is actually a parameter carried by an Access Point (Access Point) in response to a station scan, and other network parameters include a Media Access Control (MAC) Address, signal strength, encryption and authentication methods, and the like of the Access Point. It needs to be pointed out that when the Wi-Fi alternative network is scanned for network detection, if it is detected that the network cannot be accessed within the preset time, other alternative network detection is triggered. The preset time is set according to the Wi-Fi alternative network scanning detection process, and the specific time can be set by an engineer according to hardware parameters or a software algorithm, which is not described herein again.

S102, selecting and confirming an access network from the alternative networks, selecting a preset configuration Internet Protocol (IP) mode for the access network to configure an IP address of the access network, wherein the preset configuration IP mode comprises the following steps: 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 manner for configuring the IP manner of the internet protocol may be to automatically select the preset configuration IP manner according to the priority policy of the IP configuration manner. Setting the priority policy may be: the priority of the dynamic IP configuration mode is higher than that of the PPPoE configuration IP mode; the priority of the PPPoE configuration IP mode is higher than that of the static IP configuration mode. Wherein the modification authority of the priority policy can be provided for the user. The user can modify the priority policy according to personal requirements.

In a WIreless local area network, an electronic device communicates based on a WIreless-FIdelity (Wi-Fi) protocol, and in a process of accessing a network, an Access Point (AP) sends a beacon frame to a mobile terminal, where the beacon frame may include a Service Set Identifier (SSID) of the network, and a user may select a WIreless local area network that the user can join according to the SSID.

The static IP configuration is a static IP address set by a user for the electronic device according to the characteristics of the IP address of the router, and the address cannot be changed due to device restart or router restart. The Dynamic IP Configuration is automatically assigned by a Dynamic Host Configuration Protocol (DHCP) server, and the DHCP is a network Protocol of a local area network and works using a UDP Protocol. The DHCP protocol allows the server to dynamically assign IP addresses and configuration information to clients. The DHCP protocol supports a C/S structure and is mainly divided into a client and a server. The IP address allocated by the DHCP server is influenced by the address lease and the equipment state, after the lease expires, the IP address is recovered by the DHCP server, and the IP address is reallocated by the DHCP server due to the equipment restart, the router restart or the network re-access.

The PPPoE configuration mode has higher cost performance, is widely adopted in a series of applications including cell networking construction and the like, and the current popular broadband access mode such as Asymmetric Digital Subscriber Line (ADSL) uses a PPPoE protocol. PPPoE uses Ethernet to form a network with a large number of hosts, and connects to the Internet through a remote access device, and realizes control and charging functions for each host. Computers accessing the internet in the ADSL mode are mostly connected to the internet through an Ethernet card (Ethernet). The same is used with the ordinary TCP/IP method, and no new protocol is added. The dial-up networking of the modem uses a Point-to-Point Protocol (PPP) which has the functions of user authentication and IP address notification. The PPP over Ethernet (PPPoE) protocol is a technique for relaying PPP frame information in an Ethernet network, and is particularly suitable for ADSL and other systems.

The priority policy of the IP configuration may be automatically selected, mainly involving a jump from high priority to low priority, and includes, for example: in both cases, the number of the first and second cases,

first, the current IP configuration mode is automatically selected as the dynamic IP configuration mode, but the DHCP server cannot allocate the dynamic IP and automatically switches to the PPPoE configuration IP mode. The method comprises the following specific steps: detecting that the IP configuration mode is automatically selected as a dynamic IP configuration mode; and configuring a DHCP protocol according to the dynamic host, and directly switching the IP configuration mode of the client to the PPPoE mode if detecting that the physical network interface connecting end of the client does not have a DHCP server. Or, detecting that the IP configuration mode is automatically selected as a dynamic IP configuration mode; configuring a DHCP protocol according to a dynamic host, detecting that the DHCP server exists at the connection end of the physical network interface, further detecting whether a DHCP session is established between the physical network interface and the DHCP server, and finding that a call is not established between the physical network interface and the DHCP server; the IP configuration mode of the client is switched to the PPPoE mode.

Secondly, the current IP configuration mode is automatically selected as a PPPoE configuration mode, but the PPPoE server can not distribute dynamic IP and automatically switches to a static configuration IP mode. The method comprises the following specific steps: detecting that the IP configuration mode is automatically selected to be a PPPoE mode; according to the PPPOE protocol, detecting that a PPPOE server does not exist at a physical network interface connecting end of a client, and switching an IP configuration mode of the client to a static IP configuration mode. Or, detecting that the IP configuration mode is automatically selected to be a PPPoE mode; detecting whether a PPPoE server exists at the physical network interface connecting end according to a PPPoE protocol, and detecting whether a PPPoE session is established between the physical network interface and the PPPoE server; and if the call is not established, switching the IP configuration mode of the client 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 mode is higher than that of the dynamic IP configuration mode or the priority of the dynamic IP configuration mode is higher than that of the dynamic IP configuration mode. The automatic switching detection methods of the IP configuration modes are consistent, for example: if the priority of the PPPoE configuration IP mode is higher than that of the dynamic IP configuration mode, detecting that the IP configuration mode of the electronic equipment is automatically selected to be the PPPoE mode; according to the PPPOE protocol, detecting that a PPPOE server does not exist at a physical network interface connecting end of a client, and switching the IP configuration mode of the client to the dynamic IP configuration mode. Or, detecting that the IP configuration mode is automatically selected to be a PPPoE mode; detecting whether a PPPoE server exists at the physical network interface connecting end according to a PPPoE protocol, and detecting whether a PPPoE session is established between the physical network interface and the PPPoE server; and if the call is not established, switching the IP configuration mode of the client to the dynamic IP configuration mode. Other priority policies are set, and the switching detection method of the IP configuration mode is similar, and is not described herein again.

S103, detecting that the configuration IP mode is a PPPoE configuration mode, and popping up an account information input box of a user to acquire account information input by the user;

the method for detecting the configured IP mode can monitor the occupied information of the configured IP interface of the application program through a monitoring function built in the electronic equipment, for example, the electronic equipment of an android system can create a system-level monitoring module on a system framework layer (native/frame layer), and monitor the configured IP mode of the application program through the monitoring module, or independently create a monitoring process and monitor the configured IP mode of the application program through a message transmission mechanism. For example, a monitoring module can be set up in a framework layer and run in a system service program (system _ server), and because the monitoring module is set up in a service framework layer of a system level, interaction with other system services can be facilitated without worrying about the authority problem when the system is called. If the configured IP mode is a PPPoE configuration mode, namely the condition that the account information input box of the user triggers display is met, the screen of the electronic equipment displays the account information input box, and the user fills in legal account information, so that connection can be established.

The user confirms the network to be selected by inputting the wireless network selection information, the user sets an IP configuration mode for the network to be selected, if the IP configuration mode is a PPPoE configuration mode, an account information input box of the user is popped up, and the user establishes network connection by inputting the account information. The input information comprises legal user name information and password information matched with the user name.

And S104, performing PPPoE authentication according to the input account information, and establishing connection with the access network. The account information input box is further used for backing up the account information by using a cloud server. The specific method comprises the following steps: storing the account information, uploading the account information to the cloud server, and receiving a response that the account information returned by the cloud server is successfully stored; if the client is reset or replaced, sending a request for acquiring a password corresponding to the user name to the server according to the input user name; and receiving a password corresponding to the user name issued by the cloud server, and filling the password in a password input box so as to perform PPPoE authentication on the account information of the user.

The method for configuring the IP connection access network by the PPPoE comprises the following steps: a client and an Access Concentrator (AC) acquire an Ethernet physical address of an opposite terminal, and the client and the Access Concentrator share a unique session ID; the client sends a Discovery phase Discovery Initiation (PADI) broadcast packet to a preset broadcast domain to apply for a service to an AC in the preset broadcast domain, where the preset broadcast domain may be in a cell. Or any value of the square circle 1m-1000m can be included in the range; one or more AC Discovery phase reply (PADO) messages in a preset broadcast domain can provide service for a client; the client host selects an AC according to preset requirements, and sends a Discovery phase Request (PADR) message to the AC to Request services from the AC, wherein the preset requirements of the client host can be signal strength, distance information or safety information; the AC sends a Session acceptance (PADS) message to the client to announce that the service is provided to the client and shares a unique Session ID with the client. The client and the access concentrator establish dial-up connection through the session ID and carry out point-to-point network layer data message transmission; PPP negotiation in the PPPoE session negotiation stage is consistent with a common PPP negotiation mode; the client accesses the network and carries out data interaction. When the client or the access concentrator needs to Terminate the session, the client or the server can send a terminating message (PADT) according to the requirement, so as to disconnect the PPPoE connections of the two parties of the session.

The method provided by the embodiment of the application can further comprise the following steps:

s105, if the dialing connection established in the PPPoE mode is abnormally off-line and the abnormal off-line belongs to the preset abnormal off-line table item, the client sends a request to a server to authenticate the identity of the PPPoE client, and if the server is successfully authenticated, the dialing connection is recovered. The method specifically comprises the following steps: acquiring abnormal offline data information; inquiring the abnormal offline identification of the data information, and confirming that the abnormal offline identification is in the preset abnormal offline table entry, wherein the preset abnormal offline table entry can comprise router restart, equipment short-time power failure, link oscillation, hardware failure, client restart and the like; if the list item belongs to any one of the list items, sending an authentication message for requesting authentication of the client identity to the server; and receiving an identity authentication success response returned by the server, and recovering the abnormal offline dialing connection.

In a current network based on Point-to-Point protocol over Ethernet (PPPoE), a client and a Broadband Remote Access Server (BRAS) device are typically interconnected through a two-layer switch. When the link of the access port of the BRAS equipment vibrates or hardware fails, the client is abnormally off-line, the public network address of the BRAS equipment in the client still exists, the client can still access the public network, but the user table entry of the access port corresponding to the client on the BRAS equipment is automatically cleared, the BRAS equipment cannot send a PADT message to the client, and therefore the client cannot sense the failure. In this case, the client can only rely on its periodic keep-alive detection mechanism to sense that it has been abnormally taken off-line. Acquiring data information of abnormal offline through a client; inquiring the abnormal offline identification of the data information, and sending an authentication message for requesting authentication of the client identity to the server if the abnormal offline identification is confirmed to be in the preset abnormal offline table entry; and when receiving an identity authentication success response returned by the server, recovering the abnormal offline dialing connection. The network recovery connection mode of other conditions in the preset abnormal offline table entry is similar to the network recovery connection mode of link oscillation and hardware failure. And will not be described in detail herein.

For example, a monitoring module can be set up in a framework layer and run in a system service program (system _ server), and because the monitoring module is set up in a service framework layer of a system level, interaction with other system services can be facilitated without worrying about the authority problem when the system is called. In addition, an independent monitoring process can be created, an independent monitoring function is set and called in the process, the process can be set to be started up automatically, the command receiving line and the command inquiring line of any other application program are monitored in real time, and specifically, data information and an opening state identifier of a currently called wireless local area network interface can be captured in real time, so that whether a wireless local area network opening command is received currently or not is determined, independent development can be achieved, coupling with a system is avoided, and subsequent development and upgrading are facilitated.
