Description

Method and device for accessing wireless local area network

Background

With the development of communication technology, WiFi (Wireless Fidelity) coverage is implemented in large areas such as office buildings, shopping centers, squares, railway stations, and the like. Currently, because a WiFi coverage area of a single AP (Access Point) device is limited, WiFi in a large area is usually provided by a plurality of AP devices connected in the same wlan. As people move around in an area, mobile terminals carried by people usually need to access a wireless local area network through different AP devices in the same wireless local area network.

In the related art, after a user manually configures an SSID (Service set identifier) of an AP device in the same wlan as the same SSID, the user can access the wlan through different AP devices in the same wlan.

However, since the process of configuring the SSID requires professional knowledge, it is difficult for non-professional network personnel to operate, and when the number of AP devices is large, the AP devices are configured one by one, which is cumbersome to operate.

As shown in fig. 1A, fig. 1A is a flowchart illustrating a method for accessing a wireless local area network according to an exemplary embodiment of the present disclosure, where the method is applied to a terminal device, and the terminal device accesses the wireless local area network through an access point AP device corresponding to a first service set identifier SSID, and may include the following steps:

in step 101, when a set condition is satisfied, at least one SSID other than a first SSID currently detected by a terminal device is determined.

The terminal device in this embodiment is an electronic device with a WiFi internet access function, and in practical application, the terminal device may include: smart phones, tablet computers, smart watches, computer devices, and the like.

In this embodiment, the terminal device may scan WiFi hotspots in the current network environment through a Scanning (Scanning) operation, to obtain information of the AP device corresponding to each WiFi hotspot in the current network environment, where the information includes: the service set of the AP device identifies SSID, BSSID, signal strength, encryption, authentication method, and the like, where SSID is a network name of the AP device, and BSSID is a MAC address of the AP device.

It should be noted that, the terminal device in this embodiment may perform the scanning operation when the terminal device uses the wireless network, or may perform the scanning operation when the terminal device uses the data traffic, which is not limited in this embodiment.

The AP (Access Point) device in this embodiment is a wireless switch in a wireless network, is an Access Point for a terminal device user to enter a wired network, and is mainly used for home broadband, enterprise internal network deployment, and the like, and has a wireless coverage distance of several tens of meters to hundreds of meters, and a main technology of 802.11X series. In practical applications, the AP device may include: the system comprises a simplex AP device and an extended AP device, wherein the simplex AP device does not have a routing function and is equivalent to a wireless switch, and the extended AP device has a routing function, namely a wireless router.

In step 102, a second SSID in the same wireless local area network as the first SSID is determined from the at least one SSID.

In this embodiment, the AP device corresponding to the first SSID and the AP device corresponding to the second SSID are in the same wireless local area network.

In step 103, the AP device corresponding to the second SSID accesses the wireless lan.

In this embodiment, the wireless local area network accessed by the terminal device through the AP device corresponding to the second SSID is the same as the wireless local area network accessed through the AP device corresponding to the first SSID.

In an exemplary application scenario, as shown in fig. 1B, the application scenario includes: the terminal device 100 accesses a wireless local area network through the first AP device 110, the SSID of the first AP device is a first SSID, the first AP device 110, the second AP device 120, and the third AP device 130 are all in the first wireless local area network, the fourth AP device 140 is in the second wireless local area network, and all the four AP devices can be scanned by the terminal device 110.

When the set conditions are met, the terminal device may obtain, by scanning the current network environment, the first SSID of the first AP device 110, the SSID of the second AP device 120, the SSID of the third AP device 130, and the SSID of the fourth AP device 140, and because the terminal device 100 currently accesses the wireless lan through the first AP device 110, a second SSID that is in the same wireless lan as the first SSID is determined from the SSID of the second AP device 120, the SSID of the third AP device 130, and the SSID of the fourth AP device 140 obtained by scanning this time, for example, when it is determined that the SSID of the second AP device 120 is the second SSID, the terminal device 100 accesses the wireless lan through the second AP device 120.

As can be seen from the foregoing embodiment, in this embodiment, a second SSID that is in the same wireless local area network as a first SSID can be determined from other SSIDs that are different from the first SSID and are currently detected, and then the AP device corresponding to the second SSID is accessed to the wireless local area network, so that the AP devices corresponding to different SSIDs in the same wireless local area network are accessed to the same wireless local area network, and a user does not need to configure all the AP devices in the same wireless local area network as the same SSID in advance, which is relatively simple to operate.

As shown in fig. 2, fig. 2 is a flowchart illustrating another method for accessing a wireless local area network according to an exemplary embodiment of the present disclosure, where it may be determined whether two different SSIDs are in the same wireless local area network according to authentication information, and in this case, the method may include the following steps:

in step 201, when a set condition is satisfied, at least one SSID other than the first SSID currently detected by the terminal device is determined.

Step 201 in this embodiment is similar to step 101 in the embodiment shown in fig. 1A, and this embodiment is not described again.

In step 202, determining whether a first SSID and a second SSID of the at least one SSID are in the same local area network according to first authentication information corresponding to the first SSID and at least one authentication information corresponding to the at least one SSID; when at least one authentication information contains first authentication information, determining that one SSID corresponding to the first authentication information in the at least one authentication information is a second SSID which is in the same wireless local area network with the first SSID.

It should be noted that, at present, although the SSIDs of the AP devices in the same wireless lan are not completely the same, the authentication information corresponding to the AP devices is the same, and the terminal device is connected to the AP device through the SSID of the AP device and the corresponding authentication information.

In this case, the embodiment may determine whether the first SSID and the second SSID are in the same wireless lan by comparing whether the authentication information corresponding to the first SSID and the second SSID are the same, and determine that the first SSID and the second SSID are in the same wireless lan when the authentication information corresponding to the first SSID and the second SSID are the same; and when the authentication information corresponding to the first SSID is different from the authentication information corresponding to the second SSID, determining that the first SSID and the second SSID are in different wireless local area networks.

The authentication information in this embodiment may include: login password and MAC address of gateway.

In this embodiment, in a case that the terminal device accesses the wireless local area network through the AP device corresponding to the at least one SSID before, if the terminal device locally stores at least one authentication information corresponding to the at least one SSID, the terminal device may obtain, from the local area, the first authentication information corresponding to the first SSID and the at least one authentication information corresponding to the at least one SSID.

The first authentication information corresponding to the first SSID and the at least one authentication information corresponding to the at least one SSID may also be obtained by other terminal devices, and when the authentication information is obtained by other terminal devices, the terminal device executing the method of this embodiment may obtain a lan classification result obtained according to the authentication information obtained by other terminal devices through a certain way, for example, other terminal devices upload the lan classification result obtained according to the authentication information to a server, and the terminal device directly obtains the lan classification result from the server.

In step 203, the AP device corresponding to the second SSID accesses the wireless lan.

Step 203 in this embodiment is similar to step 103 in the embodiment shown in fig. 1A, and this embodiment is not described again.

As can be seen from the above embodiments, in the embodiments, whether two different SSIDs are in the same wlan can be determined according to the authentication information corresponding to the two different SSIDs, and when the authentication information is the same, the two different SSIDs are in the same wlan, so that access to the same wlan is achieved through AP devices corresponding to different SSIDs in the same wlan, without requiring a user to configure all AP devices in the same wlan as the same SSID in advance, and the operation is relatively simple.

As shown in fig. 3, fig. 3 is a flowchart illustrating another method for accessing a wireless local area network according to an exemplary embodiment of the present disclosure, where whether two different SSIDs are in the same wireless local area network may be determined according to a roaming SSID list, and the method may include the following steps:

in step 301, when a set condition is satisfied, at least one SSID other than the first SSID currently detected by the terminal device is determined.

Step 301 in this embodiment is similar to step 101 in the embodiment shown in fig. 1A, and this embodiment is not described again.

In step 302, a roaming SSID list corresponding to the first SSID is obtained from the server, where the roaming SSID list records at least one SSID in the same wireless lan as the first SSID and a MAC address of the AP device corresponding to each SSID.

The server in this embodiment stores a roaming SSID list, and the roaming SSID list may be a list manually configured by a server maintainer or a list automatically generated by the server according to information uploaded by one or more terminal devices, where a generation process of the list is described in the embodiment shown in fig. 4 below.

For ease of understanding, the roaming SSID list is shown below in table 1.

In step 303, when the at least one SSID includes an SSID that is the same as an SSID in the roaming SSID list and the MAC addresses of the AP devices corresponding to the same SSID are the same, it is determined that one SSID of the same SSID is a second SSID in the same wireless lan as the first SSID.

With reference to table 1, for example, the SSID of the AP device corresponding to the first SSID is SSID1 and the MAC address is MAC address 1, the SSID of the AP device corresponding to the second SSID is SSID2 and the MAC address is MAC address 2, and table 1 shows that both the first SSID and the second SSID are in the first wireless lan.

In step 304, the AP device corresponding to the second SSID accesses the wireless lan.

Step 304 in this embodiment is similar to step 103 in the embodiment shown in fig. 1A, and this embodiment is not described again.

As can be seen from the above embodiments, in this embodiment, whether two different SSIDs are in the same wlan can be determined by automatically searching the roaming SSID list, and when it is recorded in the roaming SSID list that two different SSIDs are in the same wlan, it is determined that the two different SSIDs are in the same wlan, so that access to the same wlan is achieved through AP devices corresponding to different SSIDs in the same wlan, without requiring a user to configure all AP devices in the same wlan as the same SSID in advance, which is relatively simple to operate.

Because the authentication information corresponding to the SSIDs in the same wlan is the same, it can be determined whether different SSIDs are in the same wlan according to the authentication information, based on which, in another embodiment provided by the present disclosure, the embodiment may add the following steps on the basis of the embodiment shown in fig. 3:

Since AP devices are sometimes added or deleted in the wlan, in order to ensure the accuracy and comprehensiveness of the contents in the roaming SSID list stored in the server, the terminal device in this embodiment may classify the SSID and the MAC address of the locally connected AP device according to the authentication information, and feed back the classification result to the server, so that the server updates the roaming SSID list.

In another embodiment provided by the present disclosure, on the basis of any one of the above method embodiments, the step in this embodiment of accessing to the wireless local area network through the AP device corresponding to the second SSID may include:

acquiring first authentication information corresponding to the first SSID from the terminal equipment locally; and connecting to the AP equipment corresponding to the second SSID based on the first authentication information and the second SSID.

Because the first SSID and the second SSID are in the same wireless local area network, the authentication information corresponding to the first SSID is the same as the authentication information corresponding to the second SSID; and because the terminal device accesses the wireless local area network through the AP device corresponding to the first SSID, the terminal device stores authentication information corresponding to the first SSID, that is, first authentication information.

As can be seen from the above embodiments, after it is determined that the first SSID and the second SSID are in the same wlan, the embodiment may directly read the authentication information corresponding to the second SSID from the terminal device locally, and then access the wlan through the AP device corresponding to the second SSID based on the authentication information, without requiring the user to manually input the authentication information, which is relatively simple to operate.

In another embodiment provided by the present disclosure, on the basis of any one of the above method embodiments, the preset condition in this embodiment may include: and the network quality score of the AP equipment corresponding to the first SSID is lower than a preset threshold value.

In order to ensure the network quality of the terminal device, the terminal device may score the network quality of the AP device corresponding to the first SSID at intervals of a certain duration, and the scoring process may include the following steps S1 and S2, wherein,

s1, acquiring a network quality parameter of the AP device corresponding to the first SSID, where the network quality parameter may include: signal strength RSSI, signal-to-noise ratio, network transmission rate, or operating frequency band;

and S2, scoring the network quality of the AP equipment corresponding to the first SSID according to the acquired network quality parameters and the preset scoring rules.

For example, the network quality parameters include RSSI, network transmission rate, and operating frequency band, and when the network transmission rate of the AP device corresponding to the first SSID is lower than a set rate threshold, the roaming score is started. The scoring rule is as follows: score +14 when RSSI > -80dbm for the AP device; score +8 when RSSI of AP device is < -80 dbm; when the operating band of the AP device is 5G spectrum and RSSI > -60dbm, score +5 (60 dbm-RSSI).

As can be seen from the above embodiments, in this embodiment, the network signal quality of the AP device can be determined according to the network quality parameter of the AP device, the AP device with poor network signal quality can be found in time, the AP device with strong signal quality can be screened for connection, and the situations that the network access speed of the terminal device is slow due to poor network signal quality of the AP device can be avoided.

In another embodiment provided by the present disclosure, on the basis of any one of the above method embodiments, the authentication information in this embodiment may include: login password and MAC address of gateway.

It should be noted that the MAC address of the gateway is a different concept from the MAC address of the AP device, the MAC address of the gateway is unique in a wireless lan, and the MAC address of the AP device is used to identify the uniqueness of the AP device in the network.

As shown in fig. 4, fig. 4 is a flowchart illustrating another method for accessing a wireless local area network according to an exemplary embodiment of the present disclosure, which is applied to a server, and the method may include the following steps:

in step 401, a list acquisition request sent by a terminal device is received.

In step 402, a roaming SSID list corresponding to the first SSID and requested by the list acquisition request is sent to the terminal device, where the roaming SSID list records at least one SSID in the same wireless lan as the first SSID and a MAC address of the AP device corresponding to each SSID.

The server in this embodiment stores a roaming SSID list, which may be a list manually configured by a server maintenance person or a list automatically generated by the server.

As can be seen from the foregoing embodiments, the server in this embodiment may send the locally stored roaming SSID list to the terminal device, so that the terminal device determines whether two different SSIDs are in the same wireless lan according to the SSID list, thereby implementing access to the same wireless lan through the AP devices corresponding to different SSIDs in the same wireless lan without a user configuring all AP devices in the same wireless lan to the same SSID in advance, which is relatively simple to operate.

In another embodiment provided by the present disclosure, the embodiment may add the following steps on the basis of the embodiment shown in fig. 4:

In this embodiment, the server may automatically generate a roaming SSID list according to an SSID sent by the terminal device and a MAC address of the AP device, where the generation process of the roaming SSID list is as follows:

the method comprises the steps that a server receives a plurality of SSIDs which are sent by one or more mobile terminals and classified according to a wireless local area network and MAC addresses of AP equipment corresponding to the SSIDs;

after receiving the SSIDs and the MAC addresses of the AP devices corresponding to the SSIDs, the server may classify and summarize the SSIDs and the MAC addresses of the AP devices corresponding to the SSIDs according to the differences of the wireless local area networks, and divide the SSIDs and the MAC addresses of the AP devices corresponding to the SSIDs in the same wireless local area network into one wireless local area network, thereby generating a roaming SSID list.

On one hand, since the AP device is sometimes added or deleted in the wlan, in order to ensure the accuracy and comprehensiveness of the content in the roamable SSID list stored in the server, the server in this embodiment may receive, in real time, the SSID and the MAC address of the AP device that is locally connected to the terminal device and is sent by the terminal device according to the authentication information, so as to update the roamable SSID list in real time; on the other hand, the roaming SSID list can be generated according to the AP device connection condition uploaded by one or more terminal devices, so that the determination is performed by using the list, and the method is more accurate and higher in efficiency.
