Description

A kind of login method of Wi-Fi hotspot
Technical field
The present invention relates to wireless communication field, more specifically, relate to and a kind ofly realize the login method that user terminal accesses Wi-Fi hotspot automatically.
Background technology
WiFi is a kind of wireless local area network technology, defers to IEEE 802.11 protocol family, comprises IEEE 802.11a/b/g/n etc.The AP(access point of WiFi, focus) pattern is the major way that terminal uses WiFi access network.An AP to its SSID(service set identifier of all terminal broadcast in its signal coverage areas, service set), terminal is determined to log in this AP account number used and password by the SSID received.Because the SSID of each AP can freely name, if adjacent multiple AP adopt same SSID, then the terminal being in these AP signal overlap regions will face problems.As shown in Figure 1, mobile terminal M4 is positioned at the signal overlap region of two focus AP1 and AP2, AP1 with AP2 adopts individual login mode (namely without account number cipher log in) and SSID is identical and password is different, then M4 login wherein any one AP time cannot determine password used according to SSID.In order to avoid the problems referred to above caused because of duplication of name SSID, one in practice effective method be make each AP adopt different SSID.
SSID is the character string that the length be defined in certain character set (such as, ASCII, Unicode etc.) is no more than 32 characters, and SSID may be the substring of another SSID.As shown in Figure 2, the SSID being numbered T1, T2 and T3 is defined in character set { a, b, c, the character string on 1,2,3}, and T1 is a substring of T2 and T3.For convenience of describing, the length claiming the Longest Common Substring of two SSID is both matching lengths.Such as, the Longest Common Substring of T1 and T2 is abc, and therefore both matching lengths are 3.Further, if the matching length of two SSID is not 0, then one of them is claimed to be another coupling.Such as, the matching length of T1 and T2 is non-vanishing, and therefore T1 is a coupling of T2, and vice versa.Especially, claim the coupling of two SSID of the same name to be one and mate completely, and the coupling of two different name SSID is Incomplete matchings.
Prior art proposes multiple technical solution for the problem such as search identification and access of wireless signal, specific as follows:
1) provided service is divided into multiple territory by the access point apparatus in the method for device of wireless local area network access point managing mobile terminal, and arrange different SSID for each territory, thus mobile terminal can according to own service demand each service-domain by different SSID access devices.
2) method of Network Recognition in WLAN (wireless local area network), its MAC Address using overall situation unique distinguishes extended service set ESS as mark.
3) WLAN cut-in method, Apparatus and system, the problem that the accuracy in order to solve terminal access WLAN in prior art is lower.By using unaware authentication techniques, make when mobile terminal to search is to the SSID of periphery AP, it can use the user account number that is stored in advance in this locality and password, and oneself is dynamically connected this AP.
4) device using access technology identifier to facilitate network to select and correlation technique is also had, specifically, mobile terminal is at local maintenance signal access list, and when terminal receives the signal registered in lists, it is from the AP of this signal of broadcast that is dynamically connected.If receive multiple registration signal simultaneously, it connects one of them according to predefine priority.
Summary of the invention
The present invention, for overcoming the duplication of name SSID problem described in above-mentioned prior art, first proposes a kind of login method of Wi-Fi hotspot, and the method allows the Wi-Fi hotspot using same account number and the multiple different SSID of password login.
For solving the problems of the technologies described above, technical scheme of the present invention is as follows:
For achieving the above object, the present invention proposes a kind of login method of Wi-Fi hotspot, client stores a focus AP log form in this locality, and every bar record comprises SSID, account number, password and pattern field, and the method for automatic login of client side WIFI hot spot AP comprises the following steps:
S1. client receives the SSID information of periphery AP broadcast, and chooses one of them SSID(and can choose according to the power of signal);
S2. the maximum SSID of the priority obtained with step S1, as keyword search AP log form, chooses pattern-word segment value with the consistent record of AP login mode, calculates the matching length of record ssid field value and keyword; If there are many records is not 0 with keyword match length, then calculates the priority of every bar matched record, choose the record that priority is maximum; As: define a two-level priority { matching length, SSID length }, by the number of character contained by the matching length of more each matched record ssid field value and this field value, from candidate record, choose one that the maximum and ssid field of matching length is the shortest;
Account and the password of the record correspondence S3. obtained with step S2 log in WIFI hot spot AP automatically; This WIFI hot spot AP is the WIFI hot spot AP corresponding to SSID that step S1 chooses.
Known existing conventional WiFi login mode WPA2-PSK a guy and enterprise two kinds, the former only need input password, and latter need input account number and password.The Wi-Fi hotspot login method that the present invention applies for supports above two kinds of secure log modes simultaneously.
Further, client is automatically logging in AP process, when because when matched record does not exist or account number, password bad cause login failure, then client upgrades as follows and safeguards AP log form:
1) in step s 2, the matching length in the record that the SSID of AP finds in log form is 0, then point out that user manually inputs account number, password to log in AP, and will record { SSID, account number, password, pattern } and add in log form after logining successfully;
Or
2) when the Incomplete matching of SSID finding AP in step s 2, and in step s3 because the account number in this matched record and password bad cause automatic login failure, user is then pointed out manually to input account number and password to log in AP, and by { SSID after logining successfully, account number, password, pattern } add in log form;
Or
3) if find one of the SSID of AP to mate completely in login step S2, and in step s3 because the account number in this matched record and password bad cause automatic login failure, then point out user manually to input account number and password to log in AP, and after logining successfully, upgrade the account number of respective record in log form and password field is user input values.
Further, the ssid field value storage of described client end AP log form is the reversion character string of its corresponding SSID, and records in AP log form and arrange from small to large according to the dictionary order of this field value in advance.
Further, the reversion character string of the SSID that described use step S1 obtains, as keyword search AP log form, chooses the record that pattern field is consistent with the AP login mode of step S1, calculates the matching length of this keyword and each record ssid field; Concrete mode is, client scan A P log form from small to large first by number, the record that filtered model field is inconsistent, by the ssid field value of character comparison keyword and each record from left to right, and the longest common prefix length of both calculating; Thereafter, using position in matching length and table as priority, successively comparison match record matching length and be recorded in position in table, and be finally all the candidate record of maximum from multiple matching length and be chosen at the most forward one in position in table.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
1. prior art records account number and password according to SSID, different but log in account number each AP identical with password and need to store a record respectively in the log form of client to SSID.And the focus login method that the present invention proposes supports the Wi-Fi hotspot of same account number SSID different from password login.
2. login method of the present invention has good compatibility, only need realize login method of the present invention in the focus login module of client, just normally can run in existing WiFi equipment and network.
