Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.

The network access method provided by the embodiment of the disclosure can be applied to a scene of detecting the network connection state, for example, a scene of accessing a wireless network according to the network connection state when a station performs network selection connection, or a scene of detecting whether the network state is successfully connected when the station uses the current wireless network.

In the related art, the beacon of the wireless access point includes two layers of network load information (QBSS Load Element) for identifying the load condition of the current wireless access point, and the station can flexibly select a low-load wireless access point to access the wireless network according to the load condition of the current wireless access point.

In one scenario, there are multiple wireless access points around the current station, and among these wireless access points, there is a condition that the wireless access point is successfully connected to the network or a condition that the wireless access point is disconnected from the network. In the related art, when a station selects a wireless access point, only the load condition of the wireless access point is considered, and the state that the wireless access point is connected to a network or not connected to the network is not considered. The information broadcast by the wireless access point to the station also does not include information whether the wireless access point can access the network. In this scenario, the station may choose to connect to a wireless access point that is not connected to the network, making the user experience poor.

In another scenario, the current station has access to a wireless access point that is in a network connection state, and the wireless access point is disconnected from the wireless network due to certain factors, such as operator network state events, network cable unplugging, power outage, etc. The wireless access point cannot actively inform the station that the network connection is disconnected, and the station senses longer time delay of the wireless network state due to the fact that the wireless access point is polled for the time length and complex logic detects the current network state. If the network is disconnected when the station uses the current network, the station automatically selects other available networks and re-accesses the other available networks, but a longer time delay exists. If the time length of the station polling is shortened, the station can reduce the time delay for sensing the disconnection of the network, but the extra load of the station system is increased, and the user experience is poor.

In view of this, the disclosure provides a method for accessing a network, which adds a network connection state (QBSS Internet Load Element) of a three-layer network in a tag parameter of a wireless access point beacon to identify the network state of the three-layer network of the wireless access point as a network connection state or a network unconnected state. When the station selects the network, the wireless access point broadcasts a beacon frame, and the station receives the beacon frame broadcast by the wireless access point and periodically polls the network state of the wireless access point to acquire the network state of the wireless access point. A wireless access point in a network connected state can be preferentially selected. If the network state of the wireless access point is in the network unconnected state, the station acquires the information of the network unconnected state of the wireless access point according to the beacon frame of the wireless access point, so that the station can sense the disconnection of the wireless network in a short time, and select the network again to ensure the network surfing experience of a user.

The network connection state is a network connection state of a three-layer network.

Fig. 1 is a flow chart illustrating a method of accessing a network according to an exemplary embodiment. As shown in fig. 1, the method of accessing a network is used for a station, and includes the following steps.

In step S11, a beacon frame broadcasted by the wireless access point is monitored, and a network state identifier is set in the beacon frame, where the network state identifier is used to characterize a network connection state of the wireless access point, and the network connection state is a network connection state of a three-layer network of the wireless access point.

In step S12, a wireless access point to be accessed is determined based on the network status identification.

In step S13, the wireless access point to be accessed is determined based on the network connection state of the wireless access point.

In step S14, the network is accessed based on the wireless access point to be accessed.

In the embodiment of the disclosure, a station listens to a wireless access point to broadcast a Beacon frame, wherein the Beacon frame comprises a Beacon (Beacon) of the wireless access point, and a probe report (probe response) sent to the station according to a probe request (probe request) sent by the station. The beacon, probe request, and probe report include network status identification, tagging parameters (tagged parameters), and two-layer network load information (QBSS Load Element). Wherein the network state identifier is used for indicating the network connection state of the three-layer network of the wireless access point.

In the embodiment of the disclosure, the beacon included in the beacon frame is wireless access point information actively broadcast to the station by the wireless access point, and the probe report included in the beacon frame is a probe report sent to the station by the wireless access point according to the probe request when the station sends the probe request to the wireless access point.

In the embodiment of the disclosure, a station acquires a network connection state sent by a wireless access point according to a beacon frame. The network connection state is a connection state between the wireless access point and the network, and comprises a network connection state and a network unconnected state. If the wireless access point is in an unconnected state with the network, the station accesses the wireless access point and cannot connect with the network through the wireless access point. If the wireless access point is in a network connection state with the network, the station is accessed to the wireless access point and can be connected with the network through the wireless access point. The station determines a wireless access point to be accessed according to the network connection state between the wireless access point and the network, and accesses the network according to the wireless access point to be accessed.

In an exemplary embodiment, taking the case that a wireless access point a and a wireless access point B exist around a station, the wireless access point a and the network are in a network connection state, and the wireless access point B and the network are in a network non-connection state. The station acquires the network connection states of the wireless access point A and the wireless access point B, judges that the wireless access point A is in the connection state with the network, determines the wireless access point A as the wireless access point to be accessed, and accesses the wireless access point A and the network.

According to the method for accessing the network, the station can acquire the connection state of the wireless access point and the network according to the beacon frame of the wireless access point, so that when the station selects the wireless access point to access the network, the station can select the access point in the network connection state to access, the situation that the wireless access point accessed by the station possibly has the network unconnected state is avoided, the accuracy of the station in selecting the wireless access point to access the network is improved, and the experience of a user in using the network is improved.

The method for accessing the network provided by the embodiment of the disclosure can judge whether the wireless access point is in the network connection state or not through the identification value.

Fig. 2 is a flowchart illustrating a method of determining a network connection status of a wireless access point, according to an example embodiment. As shown in fig. 2, determining a network connection status of a wireless access point based on a network status identification includes the following steps.

In step S21, an identification value corresponding to the network state identification is determined, wherein different network connection states correspond to different identification values.

In step S22, the network connection state of the wireless access point is determined based on the identification value corresponding to the network state identification.

In the embodiment of the disclosure, a station determines a network connection state of a wireless access point through an identification value corresponding to a network state identification, and different network connection states correspond to different identification values. The identification value corresponding to the network connection state is preset.

In an example, referring to table 1, an identification value corresponding to a network state preset in a custom module of an 802.11 wireless protocol is shown. As shown in table 1, in the custom module of the 802.11 wireless protocol, an Information element (Information Element, IE), specifically, QBSS Internet Load Element IE, a command function (vendor specific) with an attribute name of 211, a Length (Length) of 5 bytes, and Information (Information) including an organization unique identifier OUI (Organizationally Unique Identifier), a first column of a manufacturer identification code, a second column of an organization unique identifier type, a third column of a value of QBSS Internet Load Element, 0200 indicating that the network connection state of the wireless access point is a network unconnected state, and 0201 indicating that the network connection state of the wireless access point is a network connected state are preset. Wherein 211 is a field used by the manufacturer to add IEs to the 802.11 wireless protocol, which can be modified as needed.

TABLE 1

In an exemplary embodiment, the station acquires the beacon frame sent by the wireless access point, and takes the value of Data as 0201 when the wireless access point is in the network connection state, and takes the value of Data as 0200 when the wireless access point is in the network non-connection state as an example. If the station acquires the identifier value of 0200, the network connection state of the wireless access point is determined to be the network unconnected state, and if the station acquires the identifier value of 0201, the network connection state of the wireless access point is determined to be the network connection state.

In the method for accessing the network provided by the embodiment of the disclosure, the network connection state of the wireless access point can be determined by the identification value corresponding to the network state identification.

In the embodiment of the disclosure, if a plurality of wireless access points exist around a station, when the station performs automatic network selection, the wireless access point to be accessed can be determined according to the scores of the plurality of wireless access points.

Fig. 3 is a flowchart illustrating a method of determining a wireless access point to be accessed, according to an example embodiment. As shown in fig. 3, the determination of the wireless access point to be accessed based on the network connection status includes the following steps.

In step S31, in response to the number of wireless access points being plural, scores of the plural wireless access points are determined, and the scores are scored based on the network connection status information.

In step S32, the wireless access point with the highest score is selected as the wireless access point to be accessed.

In the embodiment of the disclosure, if a plurality of wireless access points exist around a station, the plurality of wireless access points can be scored according to network connection state information to determine the scores of the plurality of wireless access points, and the station selects the wireless access point with the highest score as the wireless access point to be accessed. An access request is sent to a wireless access point to be accessed, and the station accesses the network.

The scoring may be based on a signal Score (RSSI Score) of the wireless access point, two-layer load information (throughput Score) of the bypass load wireless access point, and a network connection status identifier value QBSS Internet Load Element, where the scoring is performed on the plurality of wireless access points, and the station selects the wireless access point with the highest Score as the wireless access point to be accessed.

It will be appreciated that the scoring bases described above are merely exemplary, and that the present disclosure is capable of scoring wireless access points according to other scoring forms including network connection status identification values, and selecting the wireless access point with the highest score as the wireless access point to be accessed.

In an exemplary embodiment, taking an example that the wireless access point a is in a network unconnected state and the wireless access point B is in a network connected state, the station scans and/or transmits a probe request to the wireless access point A, B, and the wireless access point A, B transmits a beacon and a probe report to the station, where the beacon array includes a signal fraction of the wireless network A, B, two-layer load information of the wireless access point A, B, and QBSS Internet Load Element of the three-layer network, and the station scores the wireless access point according to the above information. Since the wireless access point a is in the network unconnected state and the wireless access point B is in the network connected state, the score of the wireless access point a is lower than the score of the wireless access point B, for example, the score of the wireless access point a is 49 and the score of the wireless access point B is 55. The station automatically selects the wireless access point B for connection and accesses the wireless network B.

According to the embodiment of the disclosure, the station can select the wireless access point capable of being connected to the wireless network to connect, so that after the station is accessed to the wireless access point, the network can be smoothly used, and the experience of using the network by a user is improved.

By the method for accessing the network, the station can select the wireless access point with the highest score from a plurality of wireless access points to connect so as to ensure the Internet surfing experience of the user.

The method for accessing the network can also quickly acquire the network unconnected state of the current network access point and redetermine the wireless access point to be accessed when the wireless access point is accessed by the station if the network connected state of the wireless access point changes, so that the experience of a user on using the network is improved.

Fig. 4 is a flow chart illustrating a method of accessing a network according to an exemplary embodiment. As shown in fig. 5, the following steps are also included.

In step S41, the network connection status of the wireless access point is periodically polled.

In step S42, in response to the polling that the network connection status is the unconnected status, the wireless access point to be accessed is determined again based on the network connection status.

In the embodiment of the disclosure, a station polls a network connection state of a wireless access point, and when the station accesses the wireless access point and the network state of the wireless access point which is polled to access is in a network unconnected state, the wireless access point to be accessed is redetermined according to a wireless access point beacon frame existing around the station. The polling may be that the station transmits a probe request to the wireless access point, and the wireless access point transmits a probe report to the station in response to the probe request.

In an exemplary embodiment, a station polls a wireless access point for 3 seconds, where a polling manner is to send a probe request to the wireless access point, and the station sends the probe request to the wireless access point every 3 seconds, and if a network connection state of the current access point is identified as a network unconnected state in a probe report in response to the probe request, the station redetermines the wireless access point to be accessed according to beacon frames of wireless access points existing around, and accesses the network.

Fig. 5 shows a schematic diagram of a network connection state change and redetermining a wireless access point to be accessed in an exemplary embodiment of the present disclosure. Referring to fig. 5, taking a station as an example, the terminal has accessed to the wireless network, and when detecting that the screen of the terminal is on, the wireless network module of the terminal can periodically acquire some information of the current wireless network access point of the terminal, and acquire the wireless network access point QBSS Internet Load Element which is currently accessed. Where the period may be 3 seconds, the information may include RX TX and RSSI signals. If the Data value of QBSS Internet Load Element acquired by the terminal is 0201, the terminal polls according to the period, and if the Data value of QBSS Internet Load Element acquired by the terminal is 0200, the wireless access point is in a network unconnected state, and the terminal determines the wireless access point to be accessed again.

According to the method provided by the embodiment of the disclosure, since the terminal periodically polls the wireless network access point information, the terminal can quickly sense when the network connection is disconnected, so that the time for the terminal to sense the disconnection of the network is greatly reduced, and the QBSS Internet Load Element is arranged in the beacon, so that the extra power consumption and the system load of the system are not increased.

By the method for accessing the network, the station can acquire the network connection state of the wireless access point in a short time, monitor the network connection state of the access point, and re-determine the wireless access point to be accessed when the network connection state of the access point is acquired to be in an unconnected state. To reduce the duration of the station perceiving the network unconnected state and without adding additional power consumption.

The embodiment of the disclosure also provides a method for accessing the network, which is applied to the wireless access point.

In step S52, the network connection state of the wireless access point is determined based on the beacon frame.

In step S53, the network connection state is transmitted to the station.

In step S54, an access request of a station is received, and a connection is made with the station based on the access request of the station.

In the disclosed embodiments, a wireless access point broadcasts a beacon frame to communicate information of network connection status. The Beacon frame includes a Beacon (Beacon) of the wireless access point, and a probe report (probe response) transmitted to the station according to a probe request (probe request) transmitted by the station. The beacon, probe request, and probe report include a network status identifier, a tag parameter (taggeddameters), and two-layer network load information (QBSS Load Element). Wherein the network state identifier is used for indicating the network connection state of the three-layer network of the wireless access point. The different network connection states correspond to different identification values, and the network connection states comprise a network connection state or a network unconnected state.

In the embodiment of the disclosure, a wireless access point determines a network connection state according to a beacon frame, and sends the network connection state to a station, if the station selects the wireless access point as a wireless access point to be accessed, the station sends an access request to the wireless access point, the wireless access point receives the access request of the station, and connects with the station according to the access request of the station, so that the station can access the network through the wireless access point.

In an exemplary embodiment, the beacon frame of the wireless access point includes a beacon of the wireless access point and a probe report transmitted by the wireless access point in response to a probe request of the station. In the marking parameter of the wireless access point beacon, QBSS Internet Load Element of the network connection status is set, which is used for identifying whether the three layers of networks are connected for example, and when the station determines that the wireless access point is to be accessed, the station can acquire the network connection status sent by the wireless access point, and the network connection status or the network unconnected status is obtained.

According to the method for accessing the network, the wireless access point can send the network connection state to the station, so that the station can determine the network connection state of the wireless access point. If the wireless access point is in a network connection state, the station selects the wireless access point as the wireless access point to be accessed, and the wireless access point receives an access request of the station and is connected with the station. The wireless access point in the network unconnected state is prevented from being selected by the station to serve as the wireless access point to be accessed, and therefore the experience of a user in using the network is improved.

In the embodiments of the present disclosure, the wireless access point can also send a beacon frame to the station according to the periodic polling of the station. The polling is periodic to ensure that the station acquires the network connection status in time through the information in the beacon frame.

And when registering the network state event of the operator, acquiring the network connection state of the current wireless access point according to the network state event allocation. And in the network state detection module, the network connection state of the wireless access point can be judged according to the callback event of the network detection module of the wireless access point, and the current network state result is obtained. And sending the current network state result to the station through a beacon frame by a packet sending module of the wireless access point so that the station can sense the current network state. The beacon frame may be a beacon of the wireless access point and/or a probe report of the wireless access point.

Referring to fig. 9, the station includes a wireless network scanning module and a wireless network selecting module, wherein the wireless network scanning module is used for scanning and receiving information sent to the station, and the wireless network selecting module is used for forming a wireless access point for the station to connect according to the scanning result. The user opens a wireless network access setting so that the station can access the network, wherein the station has stored a plurality of wireless access points, and the user can connect to the network at will through own selection.

The network scanning module of the station monitors the beacon from the wireless access point and periodically sends a detection request to the wireless access point to acquire the wireless access points around the current environment of the station and the related information of the wireless access points. After receiving the probe request of the station, the wireless access point replies a probe report to the station according to the probe request. The wireless access point network status assigns the beacon and the Data of QBSS Internet Load Element field in the probe report as the identification value according to the current network condition. When the wireless access point is in a network connection state, the identification value is 0201, and when the wireless access point is in a network non-connection state, the identification value is 0200. Wherein the identification value is determined according to a preset Data item in the 802.11 wireless protocol. And the network scanning module of the station acquires a scanning result (scan result) of the wireless access point according to the beacon and the detection report sent by the wireless access point, and sends the result to the network selecting module of the station. And the network selecting module of the network forms a candidate wireless access point (candidata) for the station to connect according to the received scanning result. The station scores candidate wireless access points available for connection by the station to obtain a score for the wireless access point, the score being based on the score comprising the signal, the load information of two layers of the BSS load wireless access point, and the network connection status in the beacon frame (QBSS Internet Load Element). If one wireless access point is in a network connection state, the score of the wireless access point is higher than the score of the wireless access point in a network non-connection state. The wireless access point can be accessed by the site through automatic network selection, or can be accessed by the user-defined site, wherein the score of the wireless access point can be displayed on a network selection interface of the site. Under the condition of automatic network selection, a network selection module of a station can be automatically connected with a wireless access point with highest score; under the condition that a user customizes a wireless access point accessed by a site, the wireless access point accessed by the site can be customized according to the scoring condition of the wireless access point.
