The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
In order to better understand the access method of the wireless network and the mobile terminal disclosed in the embodiments of the present invention, the following detailed description is provided for embodiments of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an access method of a wireless network according to an embodiment of the present invention, where as shown in fig. 1, the access method of the wireless network according to the embodiment of the present invention includes the following steps:
s101, when the mobile terminal judges that the WiFi module of the mobile terminal is not accessed 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 substantial work (for example, does not perform various operations on files and programs), and the standby state refers to a state in which the mobile phone is in a standby state when the mobile phone is in a standby state. The mobile terminal WiFi module is not accessed to the wireless network, and the mobile terminal WiFi module is opened but is not connected with any access point, for example, the situation that files are downloaded through WiFi connection but a middle map is disconnected. Namely, when the mobile phone is in standby and the WiFi module is turned on but no route is connected, a command is issued to the WiFi module to indicate the current connection state, and after receiving the upper layer command, the WiFi module enters a mode of regularly receiving beacon frame signals.
The specific implementation manner of receiving and recording at least one Beacon frame signal by the WiFi module may be: when the channel number of current channel is unprocessed channel number, switch to the current channel, pass through the wiFi module is in predetermineeing the duration within range the Beacon frame signal is received to current channel to when receiving Beacon frame signal, record in predetermined Beacon frame signal set received Beacon frame signal, and be in according to the channel number that the channel list updated current channel after predetermineeing for unprocessed channel number.
Specifically, the process of connecting the mobile terminal with the wireless access point can be roughly divided into: scanning (Scanning), Authentication (Authentication), Association (Association), and the like. Specifically, when the user clicks on the WIFI on the mobile phone, the WIFI module is powered on to operate, and certainly, the driver of the WIFI module is loaded correspondingly. After the mobile phone is opened, the mobile phone displays a searched WIFI hotspot nearby, the searching process is a Scanning (Scanning) process, and the Scanning process aims to find a wireless network and then join the wireless network. To join a wireless network, it is necessary to find its network name, i.e., SSID. This SSID is actually a parameter carried by the wireless Access Point (Access Point) in response to the station scan, and other network parameters include BSSID (which can be understood as the MAC address of the Access Point), signal strength, encryption, and authentication methods. The scan types are divided into two types, one is active scanning (active scanning), and the other is passive scanning (passive scanning). The process of receiving and recording at least one Beacon frame signal through the WiFi module in the step S102 is a passive scanning process.
S102, when detecting that the system is switched from the standby state to the awakening state, the mobile terminal acquires at least one Beacon frame signal recorded by the WiFi module, and accesses a corresponding wireless network according to the at least one Beacon frame signal.
Specifically, after the WiFi module receives and records at least one Beacon frame signal, if the upper layer software wakes up the system, the recorded at least one Beacon frame signal is sent to the upper layer software for notification, otherwise, the system is not woken up.
The specific implementation manner of acquiring the at least one Beacon frame signal recorded by the WiFi module may be: and obtaining 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:
displaying at least one wireless network identifier corresponding to the at least one Beacon frame signal on a screen, wherein the at least one wireless network identifier comprises a target wireless network identifier; when the selection operation aiming at the target wireless network identification is detected, the input access authentication information is obtained; and sending the first access authentication information to a first wireless access point corresponding to the target wireless network identifier, wherein the first access authentication information is used for associating the mobile terminal to a first wireless network after the first wireless access point corresponding to the target wireless network identifier confirms the identity of the mobile terminal.
It can be seen that in the method for accessing a wireless network provided in the embodiment of the present invention, when the mobile terminal determines that the WiFi module is not accessed to the wireless network and the system of the mobile terminal is in the standby state, the mobile terminal receives and records at least one Beacon frame signal through the WiFi module, and when it is detected that the system is switched from the standby state to the awake state, the mobile terminal obtains the 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. It can be seen that when the mobile terminal judges that the mobile terminal does not access the wireless network and is in the standby state, the mobile terminal adopts passive scanning to replace active scanning to acquire an access point which can be accessed, and only when the mobile terminal detects that the system is switched from the standby state to the awakening state, at least one Beacon frame signal recorded by the WiFi module is acquired, and the mobile terminal accesses the corresponding wireless network according to the at least one Beacon frame signal, otherwise, the mobile terminal does not awaken the system. Compared with the prior art, the awakening time is shortened, meanwhile, any signal does not need to be sent in the passive scanning process, and the Beacon frame signal is accessed into the wireless network based on the received Beacon frame signal, so that the power consumption of the mobile terminal can be reduced, and the endurance time of the mobile terminal can be prolonged.
Optionally, 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 the standby state, before the WiFi module receives and records at least one Beacon frame signal, the mobile terminal may further perform the following operations:
sending a Probe Request frame; detecting whether a Probe Response frame generated by the second wireless access point in Response to the Probe request frame is received; and when detecting that a Probe Response frame generated by a second wireless access point responding to the Probe Request frame is received, sending second access authentication information to the second wireless access point, wherein the second access authentication information is used for associating the mobile terminal to a second wireless network after the second wireless access point confirms the identity of the mobile terminal.
Referring to fig. 2, fig. 2 is a flowchart illustrating another method for accessing a wireless network according to an embodiment of the present invention, consistent with the embodiment shown in fig. 1. As shown in fig. 2, the method for accessing a wireless network in the embodiment of the present invention includes:
s201, the mobile terminal sends a Probe Request frame.
S202, the mobile terminal detects whether a Probe Response P Probe Response frame generated by the second wireless access point responding to the Probe Request frame is received.
S203, when detecting that a Probe Response frame generated by a second wireless access point responding to the Probe Request frame is received, the mobile terminal sends second access authentication information to the second wireless access point, wherein the second access authentication information is used for the second wireless access point to associate the mobile terminal to a second wireless network after confirming the identity of the mobile terminal.
Specifically, the steps S201 to S203 are an active scanning process. That is, the mobile phone (STA) sends out a Probe Request frame on each channel in an active manner, requesting a specific wireless network to respond. Active scanning is an active search for networks rather than waiting for a wireless network to declare the existence of itself. A station using active scanning will scan the channels listed in the channel list in the following procedure: (1) jump to a certain channel and then wait for an indication of a frame (indicatof associating frame) or wait until the ProbeDelay timer times out. If a frame is received on this channel, it is verified that the channel is in use by a user and can be probed accordingly. The ProbeDelay timer can be used to prevent an idle channel from stopping the whole process because the station will not wait for a frame. (2) The basic DCF access process is used to obtain the medium usage right and then send out a Probe Request frame. (3) Waiting for at least a minimum channel time (MinChannelTime). a. If the medium is not busy, it indicates that no network is present and therefore can jump to the next channel. b. If the medium is very busy during the period of MinChannelTime, it continues to wait for a period of time until the longest channel time (i.e., MaxChannelTime) times out and then processes any Probe Response frames. When a mobile phone performs WIFI hotspot search, sometimes the time is long because there are multiple Access Points (APs) in the area where you are, and when the mobile phone sends out a ProbeRequest frame, the multiple Access Points (APs) respond to the Probe Response frame through a contention window (contentionwindow), and this contention process is limited to the longest channel time (i.e., MaxChannelTime). When a wireless network receives a Probe Request for searching an Extended Service Set (ESS) to which the wireless network belongs, a Probe Response frame is sent. If all wireless networks in the vicinity are to be found, the Probe Request frame may use a broadcastSSID, so that all 802.11 wireless networks in the sector respond with a Probe Response.
S204, judging that mobile terminal wiFi module does not insert wireless network, just when mobile terminal' S system is in standby state, when the channel number of current channel is unprocessed channel number, switch over to current channel, through the wiFi module is in predetermineeing the interior of duration range the Beacon frame signal is received to current channel to when receiving Beacon frame signal, record in the set of Beacon frame signal of predetermineeing the received Beacon frame signal, and the channel number of according to the current channel of channel list renewal after predetermineeing the duration is unprocessed channel number.
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 buffered to extract data related to the BSS transmitting the frames. During the scan, the station will switch between channels and will record information from any Beacon received. Beacon is designed to let the stations know the parameters needed to join a Basic Service Set (BSS) for communication.
S205, when detecting that the system is switched from the standby state to the awakening state, acquiring at least one Beacon frame signal recorded by the WiFi module from the preset Beacon frame signal set.
S206, displaying at least one wireless network identifier corresponding to the at least one Beacon frame signal on a screen, wherein the at least one wireless network identifier comprises a target wireless network identifier.
S207, when the selection operation aiming at the target wireless network identification is detected, the recorded access authentication information is obtained.
S208, sending the first access authentication information to the first wireless access point corresponding to the target wireless network identifier, wherein the first access authentication information is used for associating the mobile terminal to a first wireless network after the first wireless access point corresponding to the target wireless network identifier confirms the identity of the mobile terminal.
It can be seen that in the method for accessing a wireless network provided in the embodiment of the present invention, when the mobile terminal determines that the WiFi module is not accessed to the wireless network and the system of the mobile terminal is in the standby state, the mobile terminal receives and records at least one Beacon frame signal through the WiFi module, and when it is detected that the system is switched from the standby state to the awake state, the mobile terminal obtains the 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. It can be seen that when the mobile terminal judges that the mobile terminal does not access the wireless network and is in the standby state, the mobile terminal adopts passive scanning to replace active scanning to acquire an access point which can be accessed, and only when the mobile terminal detects that the system is switched from the standby state to the awakening state, at least one Beacon frame signal recorded by the WiFi module is acquired, and the mobile terminal accesses the corresponding wireless network according to the at least one Beacon frame signal, otherwise, the mobile terminal does not awaken the system. Compared with the prior art, the awakening time is shortened, meanwhile, any signal does not need to be sent in the passive scanning process, and the Beacon frame signal is accessed into the wireless network based on the received Beacon frame signal, so that the power consumption of the mobile terminal can be reduced, and the endurance time of the mobile terminal can be prolonged.
