Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention discloses a method for automatically accessing an AP (access point), which is shown in figure 1 and comprises the following steps:
s100, when a new terminal requests to access the AP for the first time, reading historical connection information of the new terminal;
s200, reading historical connection information of each terminal accessed to the AP;
s300, acquiring a correlation value between the new terminal and each terminal accessed to the AP according to the historical connection information of the new terminal and the historical connection information of each terminal accessed to the AP;
s400, judging whether a correlation value which is larger than or equal to a preset threshold value exists in the correlation values of the new terminal and each terminal accessed to the AP or not, if so, entering a step S500, otherwise, entering a step S600;
s500, allowing the new terminal to access the AP to realize automatic network access;
s600, the new terminal is refused to automatically access the AP.
In this embodiment, the step S200 includes: s210 reads the historical connection information of each terminal currently accessing the AP. Or: s220 reads the historical connection information of each terminal currently accessing the AP and the stored historical terminals historically accessing the AP. That is, the terminal accessing the AP includes a terminal currently accessing the AP or a terminal accessing the AP (a terminal currently and once accessing the AP), and two schemes are included here:
1. the method comprises the steps of reading historical connection information of all terminals which are currently accessed to an AP, obtaining correlation values of a new terminal and all terminals which are currently accessed to the AP according to the historical connection information of the new terminal and the historical connection information of all terminals which are currently accessed to the AP, comparing the correlation values with a preset threshold value respectively, and allowing the new terminal to be automatically accessed for the first time as long as one correlation value (the correlation value of the new terminal and one of the terminals which are currently accessed to the AP) is larger than or equal to the preset threshold value without inputting passwords manually. For example, if you go to a restaurant for eating and the colleagues go to the restaurant for the first time without connecting to the network of the restaurant, then under the condition that your colleagues are connected to the network of the restaurant, the correlation degree between your mobile phone and your colleagues 'mobile phones is judged to be high according to the read historical connection records before your colleagues' mobile phones and the read connection records before your mobile phones (the same network is connected to the company between your colleagues and your colleagues), so that even if you enter the restaurant for the first time, the user does not need to input passwords, and your mobile phones can be automatically connected to the network.
2. And reading the current historical connection information and the historical connection information of the terminal which is connected with the AP once. And judging whether the new terminal has higher correlation with the currently connected terminal or the terminal connected at one time or not by combining the historical connection information of the new terminal, and if the correlation is higher (higher than or equal to a preset threshold), automatically accessing the network. In the present scheme, on the basis of the previous scheme, historical connection information of a terminal that has been connected to the AP may also be read, but this requires that the read historical connection information of the terminal that has accessed the AP is stored in the AP, for example, after the terminal a connects to the AP, the historical connection information of the terminal a is read and stored, so that even if the terminal disconnects from the AP, the previously read historical connection information of the terminal is stored in the AP. This gives more possibilities for automatic access to the relevant new terminals for later access. Also take the wireless network of a restaurant as an example, if your colleague has gone to the restaurant to eat before, the restaurant's network is connected. Then, even if you do not go with your colleague for the first time but you go to the restaurant for eating for the first time, the correlation degree of the mobile phones of your colleague and your colleague can be judged to be very high according to the historical connection information of the mobile phones of your colleague, which is stored before, so that you are allowed to access the network without inputting a password.
Both schemes can be adopted, and in addition, in view of that historical connection information of the terminal is more and more along with the passage of time, historical connection information in a preset time period can be selected according to requirements, for example, historical connection information in the last two months can be read.
In the above embodiment, the historical connection information includes SSID, BSSID, and connection time information record of the historical connected wireless network.
The SSID (Service Set Identifier) can also be written as ESSID to distinguish different networks, there may be 32 characters at most, the wireless network card can enter different networks if it is Set with different SSIDs, the SSID is usually broadcast by the AP, and the SSID in the current area can be seen through the scan function of the XP itself. For security reasons, the SSID may not be broadcast, and the user may manually set the SSID to access the corresponding network. In brief, the SSID is the name of a lan, and only computers with the same SSID name can communicate with each other.
The BSSID refers to the MAC address of the station, (STA) at an access point, (AP) in an infrastructure mode, and the BSS is defined by the IEEE802.11-1999 wlan specification. This area uniquely defines each BSS. In an IBSS, the BSSID is a locally administered IEEE MAC address, generated from an arbitrary encoding of 46 bits. The individual/group bit of the address is set to 0. The universal/local address bit is set to 1. Colloquially, the SSID is the router broadcast address and the BSSID is the router mac address.
And acquiring the correlation degree of the new terminal and the terminal accessed to the AP according to the historical connection information of the new terminal and the terminal accessed to the AP, and judging whether the new terminal is allowed to have the authority of automatically accessing the network or not according to the correlation degree. In the historical connection information, if the new terminal and one of the terminals accessing the AP have accessed the same network once, it indicates that the two terminals have correlation, and the degree of correlation can be further determined according to the information such as the MAC address (i.e., BSSID) and connection time of the access point. For example, you and colleague a often access the network of the company, and then the comparison can determine that the correlation between you and colleague a is relatively high, so that even if you apply for accessing the network for the first time, the authority of automatically connecting the network can be obtained in view of the high correlation between you and colleague under the condition that you and colleague currently access the network or you and colleague once access the network, which is convenient and fast.
The automatic access method can be also suitable for a future intelligent household wireless device set, and by migrating one device to a new network, other devices can be migrated at the same time because the other devices and the device are in the same intelligent household wireless network before and have high correlation degree, so that the new network can be automatically accessed without independently inputting a network password on each device to connect the new network, and the management of a large number of wireless devices is greatly facilitated.
The embodiment allows the personnel who have certain intimacy with the wireless AP accessed person to share the wireless AP, so that the repeated and complicated password input work can be better saved. The identification of the wireless AP to the access person is realized, and the intelligence of the wireless AP is improved to a great extent.
Another embodiment of the present invention, as shown in fig. 2, comprises:
s100, when a new terminal requests to access the AP for the first time, reading historical connection information of the new terminal;
s200, reading historical connection information of each terminal accessed to the AP;
s310, selecting a terminal related to the new terminal from all terminals accessed to the AP as a target terminal;
s320, determining a correlation value between the new terminal and the target terminal according to the historical connection information of the target terminal and the historical connection information of the new terminal;
s410, judging whether a correlation value larger than or equal to a preset threshold value exists in the correlation values of the new terminal and the target terminal, if so, entering a step S500, otherwise, entering a step S600;
s500, allowing the new terminal to access the AP to realize automatic network access;
s600, refusing to newly read the historical connection information of each terminal accessed to the AP;
in the embodiment of the invention, a terminal related to a new terminal is selected from terminals accessed to an AP (access point) as a target terminal, then a correlation value between the new terminal and each target terminal is determined according to historical connection information of the target terminal and the new terminal, and then whether the authority of accessing a network is given is judged according to the comparison between the correlation value obtained by determination and a preset threshold value. As in the previous example of a restaurant, if the mobile phones of your colleague are connected to the network of the restaurant or are currently connected to the network of the restaurant, then if you enter the restaurant for the first time, the mobile phones of your colleague are selected from the terminals accessing the AP as the target terminals, and then the correlation values between your mobile phones and the mobile phones of your colleague are calculated. Of course, the number of the target terminals is not limited, and may be one or more. And the target terminal is selected according to the historical connection record of the new terminal, and then the target terminal is matched with the historical record of the terminal accessed to the AP (currently accessed or accessed) so as to select the target terminal associated with the new terminal. The selection threshold of the destination terminal may also be set by itself, for example, the destination terminal has once connected to the same network, or has once connected to the same network for more than a times, or history connection information records the connection records of the same BSSID, that is, the destination terminal has connected to the same router. Of course, more than two identical SSIDs (networks) may be connected in the last two months, for example, the SSIDs connected by the terminal a accessing the AP include: x, Y, Z, M, S; the SSID read that the new terminal b has connected in the last two months is: y, B, M, D, A; then, the new terminal b and the terminal a accessing the AP are both connected through the networks Y and M, so the terminal a accessing the AP can be set as the target terminal of the new terminal b, and certainly, if the terminal c accessing the AP is connected through the networks U, Y, D, a, Q, and Z in about two months, the terminal c accessing the AP can also be set as the target terminal of the new terminal b because 3 identical SSIDs (Y, D, and a, respectively) are found in match with the new terminal; after the target terminal is selected (if only two target terminals are a and c), determining the correlation value of the new terminal b and the target terminal a according to historical connection information, judging whether the correlation value is larger than or equal to a preset threshold value, if so, allowing the new terminal to access the network, otherwise, calculating the correlation value of the new terminal b and the terminal c, judging whether the correlation value is larger than the preset threshold value, if so, allowing the new terminal to access the network, otherwise, refusing the new terminal b to automatically access the network, and requiring the new terminal b to input a connection password and then verifying the access. Of course, the correlation value between the new terminal b and the target terminal a and the correlation value between the new terminal b and the target terminal c may be calculated, and then compared with the preset threshold, and the new terminal c may be allowed to access the current network only if the correlation value greater than or equal to the preset threshold exists.
Another embodiment of the present invention, as shown in fig. 3, comprises:
s100, when a new terminal requests to access the AP for the first time, reading historical connection information of the new terminal;
s200, reading historical connection information of each terminal accessed to the AP;
s311, searching whether SSID information with the recording times larger than the preset times exists or not according to SSID records in the historical connection information of the new terminal, if so, entering S312, and otherwise, entering S600;
s312, marking the SSID with the recording times larger than the preset times as a target SSID;
s313, searching whether the information record of the target SSID exists in the historical connection information of each terminal accessed to the AP, if so, entering S314;
s314, selecting the terminal which is recorded with the information record of the target SSID and is accessed into the AP as a target terminal. (ii) a
S320, determining a correlation value between the new terminal and the target terminal according to the historical connection information of the target terminal and the historical connection information of the new terminal;
s410, judging whether a correlation value larger than or equal to a preset threshold value exists in the correlation values of the new terminal and the target terminal, if so, entering a step S500, otherwise, entering a step S600;
s500, allowing the new terminal to access the AP to realize automatic network access;
s600, the new terminal is refused to automatically access the AP.
On the basis of the above embodiments, the embodiments of the present invention explain in detail the selection of the target terminal. Specifically, for example, if the preset number of times is set to 5, the network with SSID 123 and the network with SSID 456 are searched in the historical connection record of the new terminal, for example, 6 networks with SSID 123 and 8 networks with SSID 456 are found, both the network with SSID 123 and the network with SSID 456 can be used as target SSIDs, then whether a network with SSID 123 is connected or not is found in the historical connection information of the terminal accessing the AP, or whether a network with SSID 456 is connected or not is found, if yes, the terminal connected to the network 123 or the network 456 is selected as the target terminal, then a correlation value between the new terminal and the target terminal is calculated, and then the correlation value is compared with the preset correlation value to determine whether the new terminal has the authority to automatically connect to the network. Preferably, the target SSID and the target terminal may also be obtained by only searching the historical connection record of the preset time period. Or more strictly, selecting the target BSSID of the new terminal by the same method, selecting the target terminal from the terminals accessed to the AP according to the target BSSID, determining the correlation value of the new terminal and each target terminal, and comparing to determine whether to give access authority. If the correlation between the two devices is high, the number of times of connecting to the same network is also high, for example, if the two devices are co-workers, the number of times of connecting to the company network is high, and therefore, the company network can be used as the target SSID. And then searching a target terminal in the terminals accessed to the AP according to the information, and calculating the correlation degree of the new terminal and the target terminal so as to determine whether to give the new terminal the authority of automatically accessing the network.
Preferably, step S320 of the above embodiment includes: s321, determining a correlation value between the new terminal and the target terminal by adopting a preset correlation algorithm according to the historical connection information of the target terminal and the historical connection information of the new terminal; wherein, the preset correlation algorithm is as follows:
Tm＝e -h/12 (2)
wherein, R: the correlation value of the new terminal and the target terminal;
m: the number of the wireless AP of the historical connection of the target terminal is started from 1;
a: the total number of the historical access wireless APs of the target terminal;
tm: the time constant of the wireless AP with the historical connection number of m of the target terminal;
f (m): the value of the coefficient of the wireless AP with the target terminal connection number m is 1 when the BSSID of the historical connection wireless AP accessed by the target terminal and the new terminal is the same; when different, the value is 0;
h: the last connection time between the target terminal and the wireless AP with the number m is the number of months from the current time.
For example, a correlation value between the new terminal x and the target terminal y is calculated, and if the target terminal y has 5 connection records in which BSSIDs of two connections (if items 3 and 5) are present, the new terminal x has been connected. Then the correlation value between the new terminal x and the target terminal y is:
R＝[T 1 f(1)+T 2 f(2)+T 3 f(3)+T 4 f(4)+T 5 f(5)]/(T 1 +T 2 +T 3 +T 4 +T 5 )
and f (m) is a coefficient value of the target terminal, which is 1 when BSSIDs of the historically connected wireless APs to which the target terminal and the new terminal access are the same; when different, the value is 0; therefore:
R＝(T 3 +T 5 )/(T 1 +T 2 +T 3 +T 4 +T 5 )
and then, according to the connection time for connecting each AP in the connection record, obtaining the number of months (which can be decimal) from the current time, then obtaining the value of each time constant Tm according to a formula (2), and substituting the value into the formula to obtain the correlation value between the terminal x and the target terminal y. And then the judgment is carried out according to the preset correlation value. In the algorithm, the time constant Tm is closely related to the connection time, and the influence is smaller as the connection time between the directory terminal y and the wireless AP (number m) connected in history is longer than the current time. The preset correlation value can be set between 0 and 1 (including itself) according to the requirement, for example, 0.2 (i.e. 20%) is set, and the wireless network cannot be accessed if the calculated correlation value R is less than 0.2.
In this embodiment, according to the historical access records of the wireless terminal devices that are accessed, a method of calculating the degree of correlation is used to determine the access authority of the wireless terminal devices, and through calculation with the wireless terminal devices that have already been accessed to the wireless AP, the wireless terminal devices that have a higher degree of correlation can be automatically accessed, and the wireless terminal devices that have a lower degree of correlation can refuse to automatically access, and seek access by other methods, so that new people can automatically connect according to their intimacy, otherwise access by means of inputting passwords.
Another embodiment of the present invention is schematically shown in fig. 4, and the main contents thereof include:
1, a plurality of wireless terminal devices already exist in a wireless network, and the wireless AP reads the stored SSID and BSSID of the historically connected wireless AP from the wireless terminal devices; for the wireless terminal equipment which requests to join for the first time, the SSID and BSSID of the wireless AP which is connected with the wireless terminal equipment in history are read;
and 2, the wireless hotspot AP calculates the SSID and BSSID of the historical connection wireless hotspot of the wireless terminal equipment which requests access for the first time and the information retrieval algorithm of the accessed equipment to obtain a correlation value, namely an R value (Relevance value), and the wireless AP compares the R value obtained by calculation with a preset value to determine the authority of the wireless terminal equipment.
Specifically, the detailed scheme of the embodiment includes:
1, if a wireless terminal device requests to access a wireless AP, and the wireless AP does not currently access the wireless terminal device, the wireless terminal device needs to use a form of inputting a password or adopt an automatic connection technology. The wireless terminal equipment starts the authority allowing the wireless AP to acquire the historical connection record of the wireless AP, and the wireless terminal equipment records the SSID and BSSID information of the router which is connected currently. Meanwhile, the wireless AP end acquires SSID and BSSID information of the historical connected wireless AP of the equipment
2, if a wireless terminal device requests to access the wireless AP, the wireless AP end has the wireless terminal device access, at the wireless terminal device end, the wireless terminal device starts the authority of allowing the wireless AP to obtain the historical connection record, and simultaneously the wireless terminal device records the SSID and BSSID information of the router which is connected currently. At the wireless AP end, the SSID and BSSID information of the wireless AP which is in historical connection with the wireless terminal equipment which requests to join the network is obtained, algorithm processing is carried out on the SSID and BSSID information and the SSID and BSSID of the wireless terminal equipment which is in the connection state at the same time, the R value of the wireless AP is obtained, the authority of the wireless AP is output by calling the judgment logic of the R value and the preset value, different R values are obtained by calculating the wireless AP with different accessed wireless terminals until the authority is found to allow access.
And 3, the judgment logic of the wireless AP on the R value is carried out by adopting the following method:
a. if: r ≧ MCS (preset value). Then the authority: the addition is allowed.
b. If: r < MCS (preset value). Then the authority: the join is denied.
And searching in the relation table through the MCS function according to the set preset value, and searching the corresponding correlation value. The search table is as in table 1:
| preset value | Corresponding degree of correlation | Remarks for note |
| 0.9 | 90％ | Level 1 |
| 0.8 | 80％ | Stage 2 |
| 0.6 | 60％ | Grade 3 |
| 0.4 | 40％ | Grade 4 |
| 0.2 | 20％ | Others |
Table 1 relationship correspondence search table
