Background technique

With the development of computer technology, all kinds of mobile terminals (such as notebook computers, tablet computers, smart phones, personal digital assistants and other electronic devices) flock to appear, which brings great convenience to people's life and work. For example, people can make calls, take pictures, listen to music, play games, locate and so on through their smartphones. Wireless network technology is a technology that can wirelessly connect different terminals to each other. WiFi (Wireless Fidelity, Wireless Fidelity), as one of the wireless network technologies, can be networked through radio waves, and has the advantages of fast data transmission speed, no wiring, and high security. For various terminals with WiFi function, a WiFi connection method can be used to establish a connection with the wireless router within the effective range of the radio wave coverage of the wireless router, so as to realize networking.

However, for mobile terminals such as mobile phones and tablet computers, they are limited by the limitation of battery capacity. Even if they are equipped with super-capacity batteries, they are also faced with the embarrassing situation of charging once a day. Now when the mobile phone is in standby, if the WiFi is turned on but not connected to the router, the upper-layer software of the mobile phone will wake up the system regularly, and the upper-layer software will automatically initiate an active scan command. The WiFi module starts active scanning. After the active scanning is over, the scanning results are reported to the software and displayed through the software. In the above process, the wake-up time of the mobile terminal is long, which in turn leads to increased power consumption and short battery life of the mobile terminal.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

In order to better understand a method for accessing a wireless network and a mobile terminal disclosed in the embodiments of the present invention, the embodiments of the present invention are described in detail below.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a method for accessing a wireless network according to an embodiment of the present invention. As shown in FIG. 1, the method for accessing a wireless network in the embodiment of the present invention includes the following steps:

S101. When determining that the WiFi module of the mobile terminal is not connected to a wireless network and the system of the mobile terminal is in a standby state, the mobile terminal receives and records at least one beacon frame signal through the WiFi module.

Specifically, the standby state refers to a state in which an electronic device such as a mobile phone or a computer is turned on but does not perform any substantive work (eg, no operations on files and programs). The WiFi module of the mobile terminal is not connected to the wireless network is that the WiFi module of the mobile terminal is turned on but is not connected to any access point, for example, the case of downloading files through WiFi connection but disconnected in the middle picture. That is, when the mobile phone is in standby and the WiFi module is turned on but no route is connected, a command is sent to the WiFi module to indicate the current connection status. After receiving the upper-layer command, the WiFi module enters the mode of regularly receiving beacon frame signals.

Wherein, the specific implementation of receiving and recording at least one beacon frame signal through the WiFi module may be: when the channel number of the current channel is an unprocessed channel number, switch to the current channel, The WiFi module receives a Beacon frame signal on the current channel within a preset duration range, and when receiving a Beacon frame signal, records the received Beacon frame signal in a preset Beacon frame signal set, and records the received Beacon frame signal in the Beacon frame signal set. After the preset time period, the channel number of the current channel is updated to the unprocessed channel number according to the channel list.

Specifically, the process of connecting the mobile terminal to the wireless access point can be roughly divided into three processes: scanning (Scanning), authentication (Authentication), and association (Association). Specifically, when the user clicks to open the WIFI on the mobile phone, the WIFI module is powered on and runs, and of course the WIFI driver will be loaded accordingly. After the opening is completed, the mobile phone displays that the nearby WIFI hotspots have been searched. This search process is the process of scanning. The purpose of scanning is to find a wireless network and then join the network. To join a wireless network, you need to find its network name, which is the SSID. This SSID is actually the parameter that the wireless access point (Access Point) takes when responding to the workstation scan, as well as other network parameters, including BSSID (which can be understood as the MAC address of the access point), signal strength, encryption and authentication methods, etc. . There are two types of scanning, one is active scanning and the other is passive scanning. The process of receiving and recording at least one beacon frame signal by the WiFi module in the above step S102 is a process of passive scanning.

S102. When detecting that the system is switched from the standby state to the awake state, the mobile terminal acquires at least one Beacon frame signal recorded by the WiFi module, and accesses the corresponding wireless network according to the at least one Beacon frame signal.

Specifically, after receiving and recording at least one beacon frame signal through the WiFi module, if the upper-layer software wakes up the system, the recorded at least one beacon frame signal will be notified to the upper-layer software, otherwise the system will not be woken up.

Wherein, the specific implementation manner of acquiring at least one Beacon frame signal recorded by the WiFi module may be: acquiring at least one Beacon frame signal recorded by the WiFi module from the preset Beacon frame signal set.

The specific implementation manner of accessing the corresponding wireless network according to the at least one Beacon frame signal may be:

At least one wireless network identifier corresponding to the at least one Beacon frame signal is displayed on the screen, and the at least one wireless network identifier includes the target wireless network identifier; when a selection operation for the target wireless network identifier is detected, the entered access authentication information; send the first access authentication information to the first wireless access point corresponding to the target wireless network identifier, where the first access authentication information is used for the first access authentication information corresponding to the target wireless network identifier After confirming the identity of the mobile terminal, the wireless access point associates the mobile terminal with the first wireless network.

It can be seen that in the wireless network access method provided by the embodiment of the present invention, when the mobile terminal determines that the WiFi module is not connected to the wireless network and the system of the mobile terminal is in a standby state, the mobile terminal receives and records at least A beacon Beacon frame signal, when it is detected that the system is switched from the standby state to the wake-up state, obtain at least one Beacon frame signal recorded by the WiFi module, and access the corresponding Beacon frame signal according to the at least one Beacon frame signal. wireless network. It can be seen that when the mobile terminal determines that it is not connected to the wireless network and is in the standby state, it adopts passive scanning instead of active scanning to obtain access points that can be accessed, and only when it detects that the system is switched from the standby state to the wake-up state, Acquire at least one Beacon frame signal recorded by the WiFi module, and access the corresponding wireless network according to the at least one Beacon frame signal, otherwise the system is not woken up. Compared with the prior art, the wake-up time is reduced, and at the same time, the passive scanning process does not need to send any signals, and accesses the wireless network based on the received Beacon frame signal, which is beneficial for the mobile terminal to reduce power consumption and prolong the battery life of the mobile terminal.

Optionally, when it is determined that the WiFi module of the mobile terminal is not connected to a wireless network and the system of the mobile terminal is in a standby state, before receiving and recording at least one beacon frame signal through the WiFi module, the The mobile terminal can also perform the following operations:

Sending a probe request Probe Request frame; detecting whether a probe response Probe Response frame generated by the second wireless access point in response to the ProbeRequest frame is received; When the probe responds to the Probe Response frame, send second access authentication information to the second wireless access point, where the second access authentication information is used by the second wireless access point to confirm the identity of the mobile terminal Then, the mobile terminal is associated with the second wireless network.

Consistent with the embodiment shown in FIG. 1 above, please refer to FIG. 2 , which is a schematic flowchart of another wireless network access method provided by an embodiment of the present invention. As shown in FIG. 2 , a method for accessing a wireless network in an embodiment of the present invention includes:

S201. The mobile terminal sends a Probe Request frame of a probe request.

S202. The mobile terminal detects whether a probe response Probe Response frame generated by the second wireless access point in response to the Probe Request frame is received.

S203. When detecting and receiving a probe response Probe Response frame generated by the second wireless access point in response to the Probe Request frame, the mobile terminal sends second access authentication information to the second wireless access point. The second access authentication information is used by the second wireless access point to associate the mobile terminal with the second wireless network after confirming the identity of the mobile terminal.

Specifically, the above steps S201 to S203 are active scanning processes. That is, the mobile phone (station STA) sends out a Probe Request frame on each channel in an active manner, requesting a specific wireless network to respond. Active scanning is actively looking for a network, rather than waiting for the wireless network to declare itself. A station using active scanning will scan the channels listed in the channel table with the following procedure: (1) Jump to a channel, then wait for an indication of an incoming frame or wait until the ProbeDelay timer expires. If a frame is received on this channel, it proves that the channel is being used by a user and can therefore be probed. And the ProbeDelay timer can be used to prevent an idle channel from stopping the whole process, because the station does not keep waiting for the arrival of the frame. (2) Use the basic DCF access process to obtain the right to use the medium, and then send a Probe Request frame. (3) Wait at least for the shortest channel time (ie MinChannelTime). a. If the medium is not busy, it means that there is no network, so you can skip to the next channel. b. If the medium is very busy during the MinChannelTime period, continue to wait for a period of time until the longest channel time (ie, MaxChannelTime) times out, and then process any Probe Response frames. When the mobile phone searches for WIFI hotspots, it sometimes takes a long time because there are multiple access points (APs) in the area you are in. When the mobile phone sends a ProbeRequest frame, multiple access points (APs) pass through the competition window ( congestionwindow) responds to the Probe Response frame, and this contention process is limited by the longest channel time (ie, MaxChannelTime). When a wireless network receives a Probe Request searching for the Extended Service Set (ESS) to which it belongs, it sends out a Probe Response frame. To find all nearby wireless networks, the Probe Request frame can use the broadcastSSID, so that all 802.11 wireless networks in the area will respond with a Probe Response.

S204. When it is determined that the WiFi module of the mobile terminal is not connected to the wireless network and the system of the mobile terminal is in a standby state, when the channel number of the current channel is an unprocessed channel number, switch to the current channel, and pass The WiFi module receives a Beacon frame signal on the current channel within a preset duration range, and when receiving the Beacon frame signal, records the received Beacon frame signal in a preset Beacon frame signal set, and records the received Beacon frame signal in the set of Beacon frame signals. After the preset time period, the channel number of the current channel is updated to the unprocessed channel number according to the channel list.

Specifically, the mobile terminal continuously switches between the channels listed in the channel list (channel list), and waits for the arrival of the Beacon frame. Any frames received are temporarily stored for retrieval of data related to the BSS that transmitted them. During the scan, the workstation will constantly switch between channels and will log information from any Beacon it receives. Beacon is designed to let workstations know the parameters required to join a basic service set (Basic Service Set, BSS for short) in order to communicate.

S205. When it is detected that the system is switched from the standby state to the wake-up state, acquire at least one Beacon frame signal recorded by the WiFi module from the preset Beacon frame signal set.

S206. Display on the screen at least one wireless network identifier corresponding to the at least one Beacon frame signal, where the at least one wireless network identifier includes a target wireless network identifier.

S207: When a selection operation for the target wireless network identifier is detected, obtain the entered access authentication information.

S208. Send the first access authentication information to the first wireless access point corresponding to the target wireless network identifier, where the first access authentication information is used for the first wireless access point corresponding to the target wireless network identifier The point is to associate the mobile terminal with the first wireless network after confirming the identity of the mobile terminal.

It can be seen that in the wireless network access method provided by the embodiment of the present invention, when the mobile terminal determines that the WiFi module is not connected to the wireless network and the system of the mobile terminal is in a standby state, the mobile terminal receives and records at least A beacon Beacon frame signal, when it is detected that the system is switched from the standby state to the wake-up state, obtain at least one Beacon frame signal recorded by the WiFi module, and access the corresponding Beacon frame signal according to the at least one Beacon frame signal. wireless network. It can be seen that when the mobile terminal determines that it is not connected to the wireless network and is in the standby state, it adopts passive scanning instead of active scanning to obtain access points that can be accessed, and only when it detects that the system is switched from the standby state to the wake-up state, Acquire at least one Beacon frame signal recorded by the WiFi module, and access the corresponding wireless network according to the at least one Beacon frame signal, otherwise the system is not woken up.
