Description

A kind of login method of Wi-Fi hotspot
Technical field
The present invention relates to wireless communication fields, and Wi-Fi hotspot is automatically accessed more particularly, to a kind of realization user terminal Login method.
Background technology
WiFi is a kind of wireless local area network technology, defers to 802.11 protocol families of IEEE, including IEEE 802.11a/b/g/n Deng.The AP of WiFi（Access point, hot spot）Pattern is major way of the terminal using WiFi access networks.One AP to its All terminal broadcasts its SSID in signal coverage areas（Service set identifier, service set）, terminal is logical The SSID that receives is crossed to determine the account number and password that log in used in the AP.Because the SSID of each AP can be named freely, adjacent If multiple AP, using same SSID, the terminal in these AP signal overlaps regions will face problems.Such as Fig. 1 institutes Show, mobile terminal M4 is located in the signal overlap region of two hot spots AP1 and AP2, and AP1 and AP2 use personal login mode （Logged in without account number cipher）And SSID is identical and password is different, then M4 can not basis when logging in wherein any one AP SSID determines password used.In order to avoid the above problem caused by duplication of name SSID, one in practice effective method be Each AP is enabled to use different SSID.
SSID is defined in some character set（For example, ASCII, Unicode etc.）On of length no more than 32 characters Character string, and a SSID may be the substring of another SSID.As shown in Fig. 2, the SSID that number is T1, T2 and T3 is definition Character string in character set { a, b, c, 1,2,3 }, and T1 is a substring of T2 and T3.For convenience of description, claim two SSID Longest Common Substring length be both matching length.For example, the Longest Common Substring of T1 and T2 is abc, therefore the two Matching length be 3.Further, if the matching length of two SSID is not 0, it is another matching to claim one of them. For example, the matching length of T1 and T2 is not zero, therefore T1 is a matching of T2, and vice versa.Particularly, title two is of the same name The matching of SSID is one and exactly matches, and the matching of two different name SSID is an Incomplete matching.
The prior art is directed to the search to wireless signal and identifies and propose multiple technical solutions the problems such as access have Body is as follows：
1）The service that access point apparatus in the method for device of wireless local area network access point management mobile terminal will be provided Multiple domains are divided into, and different SSID is set for each domain, to which mobile terminal can pass through not according to own service demand Each service-domain of same SSID access devices.
2）The method of Network Recognition in WLAN, the MAC Address globally unique using one come area as mark Divide extended service set ESS.
3）WLAN cut-in methods, apparatus and system, to solve terminal in the prior art access WLAN accuracy it is relatively low The problem of.By using unaware authentication techniques so that as SSID of the mobile terminal to search to periphery AP, can be used advance It is stored in local user account number and password and connects the AP automatically.
4）The device and correlation technique for also facilitating network to select using access technology identifier, specifically, mobile Terminal opens signal access list in local maintenance one, when terminal receives the signal registered in lists, connects automatically Meet the AP for broadcasting the signal.If receiving multiple registration signals simultaneously, one of those is connected according to predefined priority.
Invention content
The present invention is the duplication of name SSID overcome the problems, such as described in the above-mentioned prior art, proposes a kind of login of Wi-Fi hotspot first Method, this method allow the Wi-Fi hotspot using same account number and the multiple and different SSID of password login.
In order to solve the above technical problems, technical scheme is as follows：
To achieve the above object, the present invention proposes that a kind of login method of Wi-Fi hotspot, client are being locally stored one Hot spot AP log forms, and every record includes SSID, account number, password and pattern field, automatic login of client side WIFI hot spot AP Method include the following steps：
S1. client receives the SSID information of periphery AP broadcast, and chooses one of SSID（It can be according to the power of signal It chooses）；
S2. it uses the maximum SSID of the priority that step S1 is obtained to search AP log forms as keyword, chooses pattern The field value record consistent with AP login modes calculates the matching length of record ssid field value and keyword；If there are a plurality of Record is not 0 with keyword match length, then calculates the priority of every matching record, chooses the maximum note of priority Record；Such as：A two-level priority { matching length, SSID length } is defined, of ssid field value is recorded by comparing each matching Number with character contained by length and the field value chooses matching length maximum and ssid field shortest one from candidate record It is a；
S3. corresponding account and password automated log on WIFI hot spot AP are recorded with what step S2 was obtained；WIFI hot spot AP It is the WIFI hot spot AP corresponding to the SSID of step S1 selections.
Known existing common WiFi login modes WPA2-PSK has personal and two kinds of enterprise, the former only need to input password, The latter then needs input account number and password.The apllied Wi-Fi hotspot login method of the present invention supports both the above secure log simultaneously Mode.
Further, client is during automated log on AP, when because matching record be not present or account number, password not just When really leading to login failure, then client updates and safeguards AP log forms as follows：
1) it in step s 2, when the matching length in the record that the SSID of AP is found in log form is 0, then prompts to use Family is manually entered account number, password to log in AP, and record { SSID, account number, password, pattern } is added to and is stepped on after logining successfully It records in table；
Or
2) when the Incomplete matching for the SSID for finding AP in step s 2, and in step s3 since the matching records In account number and password bad cause automated log on to fail, then prompt user to be manually entered account number and password to log in AP, and { SSID, account number, password, pattern } is added in log form after logining successfully；
Or
If 3) one that finds the SSID of AP in login step S2 exactly matches, and in step s3 since the matching is remembered Account number and password bad in record cause automated log on to fail, then user is prompted to be manually entered account number and password to log in AP, And it is user input values that the account number of respective record and password field in log form are updated after logining successfully.
Further, the ssid field value storage of the client end AP log form is that it corresponds to the reversion character string of SSID, And it records in AP log forms and is arranged from small to large according to the dictionary order of the field value in advance.
Further, the reversion character string of the SSID obtained using step S1 searches AP log forms as keyword, The pattern field record consistent with the AP login modes of step S1 is chosen, the matching of the keyword and each record ssid field is calculated Length；Concrete mode is that client scans AP log forms, the inconsistent note of filtered model field from small to large by number first Record calculates the longest common prefix length of the two by the ssid field value of character comparison keyword and each record from left to right；Its Afterwards, position in matching length and table is weighed as priority, successively the matching length of comparison match record and the position being recorded in table It sets, and is finally all to be chosen in table position in the candidate record of maximum value near preceding one from multiple matching lengths.
Compared with prior art, the advantageous effect of technical solution of the present invention is：
1. the prior art records account number and password according to SSID, but login account number different to SSID and password are identical each A AP needs the log form in client to store a record respectively.And hot spot login method proposed by the present invention supports same account The Wi-Fi hotspot of number SSIDs different with password login.
2. the login method of the present invention has good compatibility, this need to be only realized in the hot spot login module of client The login method of invention, can in existing WiFi equipment and network normal operation.
