Embodiment
The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the application, rather than the restriction to the application.It also should be noted that in order to just
The part related to the application rather than entire infrastructure are illustrate only in description, accompanying drawing.
With the development of wireless network, terminal can get neighbouring wireless network, and connected and arranged by wireless network
The traveling of table, the title (such as SSID) of wireless network around is shown to user.User selects some wireless network to be connect
Enter, and then realize and accessed by the internet based on WLAN (such as wifi).The characters such as man are as wireless network
The part of title, need to be encoded in transmitting terminal (such as radio access node), and solved in receiving terminal (such as mobile phone)
Code.But due to having much for the coded system of man, receiving terminal can not know transmitting terminal using which kind of coding staff
Formula, therefore occur that the receiving terminal decoding process used and compiling method mode that transmitting terminal uses are inconsistent, cause decoding error
Situation.Now, the wireless network name that receiving terminal is shown is the title of mess code or display mistake, causes user can not the degree of accuracy
Find objective network.
The application first judges the form of target code, looked for before being decoded to target code (SSID after coding)
To decoding algorithm corresponding to target code.Especially when target code had not only met Unicode codings but also met GBK codings, sentence
It whether there is non-commonly used word in disconnected decoded result, final decoding process determined according to judged result.Realize accurately to target
Coding is decoded, and improves SSID decoding efficiency.The technical scheme provided below in conjunction with the accompanying drawings the application is retouched in detail
State.
Fig. 1 is the flow chart that a kind of decoding algorithm that the embodiment of the present application provides determines method, and the present embodiment is applicable to
The situation that terminal-pair service set (Service Set Identifier, abbreviation SSID) is identified, this method can be by
The terminal of objective network is connected to perform, the terminal can be mobile terminal, tablet personal computer, wearable device, notebook electricity
Brain etc., this method specifically comprises the following steps：
Step 110, judge whether target code meets the first decoding algorithm and the second decoding algorithm.
Wireless access points (WirelessAccessPoint, abbreviation AP) are by the title of itself with service set
Traveling is broadcasted.When terminal is entered in the range of AP, the SSID of AP broadcast can detect.In order to guarantee data security, AP exists
Before sending SSID, SSID can be encoded.The rule of coding can according to coding method corresponding to the first decoding algorithm,
It can be coding method corresponding to the second decoding algorithm.Optionally, coding method corresponding to the first decoding algorithm is Unicode
(Unicode) decoding algorithm, coding method corresponding to the second decoding algorithm are Chinese Internal Code Specification (Chinese
Internal Code Specification, GBK) decoding algorithm.Wherein, in Unicode code characters transmitting procedure, use
UTF-8 coding transmissions, for the sake of convenient, the character of Unicode codings is also known as UTF-8 code characters, Unicode decoding algorithms
Also known as UTF-8 decoding algorithms.UTF-8 (8-bit Unicode Transformation Format) is that one kind is directed to
Unicode variable length character coding, also known as Unicode.AP can be based on any one mode pair in Unicode or GBK
SSID is encoded.In the specification that GBK is encoded and UTF-8 is encoded there is the character repeated in itself, if having used mistake during decoding
By mistake decoding process mistake then occurs, cause wifi hotspot title show mess code the problem of.
Terminal listen to AP broadcast coding SSID after, the SSID of coding form is judged first,
Determine whether to meet the first decoding algorithm, do not meet the second decoding algorithm.Or, if meet the second decoding algorithm, do not meet
First decoding algorithm.Or judge whether to meet the first decoding algorithm and the second decoding algorithm simultaneously.Or judge whether i.e.
Do not meet the first decoding algorithm and do not meet the second decoding algorithm again.
In one implementation, it can judge whether target code meets the first decoding algorithm and based on byte quantity
Two decoding algorithms.
Because GBK is encoded by the way of two byte representations, one character, therefore after target code is got,
Judge whether target code is even bit.If even bit, then it can primarily determine that and meet UTF-8 or GBK.If odd number
Position, then can determine that and only meet UTF-8.
In addition, UTF-8 is usually 2-4 positions to the character quantity of target code, if the character quantity of target code is more than 4
Position, then can determine that it is applied to GBK.
In another implementation, can be judged based on span target code whether meet the first decoding algorithm and
Second decoding algorithm.
UTF-8 span covers Chinese and English character, and GBK only covers whole Chinese texts.Therefore
GBK span whether can be exceeded according to target code, determine that target code meets and whether meet UTF-8.
In another implementation, the list of physical addresses stored is also based on, judges whether target code accords with
Close the first decoding algorithm and the second decoding algorithm.
If the communication connection that AP is successfully established with terminal, i.e. terminal have used correct SSID and have input correctly close
Code, then record the facility information of the AP and the decoding algorithm corresponding relation of use, obtain list of physical addresses in the terminal.Should
Facility information includes physical address, and obtained corresponding relation can be entered by the mode of key-value pair (physical address, decoding algorithm)
Row storage.When terminal and the AP are again coupled to, AP physical address can be first searched from the list of physical addresses of preservation, according to
The physical address determines decoding algorithm.
Specifically, first, obtain target physical address corresponding to target code.Then, whether target physical address is judged
It is present in first list and second list simultaneously, or is not present in first list and second list；First list is used to remember
The physical address of the first decoding algorithm matching is recorded, second list is used for the physical address for recording the matching of the second decoding algorithm.
If step 120, target code meet the first decoding algorithm and the second decoding algorithm, according to the first decoding algorithm
Obtain the valid data position of target code.
First decoding algorithm can be UTF-8 decoding algorithms.
If determine that target code meets the first decoding algorithm and the second decoding algorithm simultaneously, is present in step 110
Decoding algorithm using mistake causes the possibility for decoding mess code or incorrect man.
Optionally, the flag bit in target code is searched according to the first decoding algorithm；Valid data are determined according to flag bit
Position.
UTF-8 encryption algorithms are after character is converted into numeral, and every group of numeral represents a character.Between every group of numeral
Between-line spacing is entered by identifier, and for identifying character sequence.Exemplary, " 110 " mark is added before set of number
Symbol, " 10 " identifier is added before second group of numeral.Character in target code is identified, when recognizing " 110 ",
It is determined that find flag bit corresponding to first character, read the first character behind " 110 ", until reading
" 10 ", by the character between " 110 " and " 10 " as set of number.By that analogy, second group of numeral, the 3rd group of numeral are obtained
To N groups numeral, each group numeral is grouped together, obtains the valid data position in target code.
Step 130, target decoder algorithm is determined according to valid data.
It is and the first decoding algorithm that can obtain decoded result corresponding to the first decoding algorithm according to valid data.According to
First decoding algorithm is decoded to obtain the first decoded result to target code.If mess code is not present in the first decoded result,
Then can determine that the first decoding algorithm is target algorithm.Or if the digit of the first decoded result meets wireless network name
Length threshold, then the first decoding algorithm is defined as target decoder algorithm.
If WAP uses the second coding method, when terminal is decoded using the first decoding algorithm,
Obtained number of significant digit may be zero, it is also possible to number of significant digit be present but parsed according to valid data position and the first decoding algorithm
The character gone out is mess code, and the second coding method now is defined as into target decoder algorithm.
In practice, it has been found that position and quantity of the UTF-8 significance bit in target code are often fixed, therefore,
Target decoder algorithm can be determined according to the digit of valid data position.
Specifically, if identifier corresponding to UTF-8 occurs on predeterminated position in target code, and there is effect character
Quantity is predetermined number, then can determine that the first decoding algorithm is target decoder method algorithm.Identifier is " 100 ", " 10 " etc., is preset
Quantity can be 20.Determine that target decoder algorithm can save decoding checking according to the digit to valid data position, further carry
High decoding efficiency.
Further, will be according to target decoder algorithm and another decoding algorithm after target decoder algorithm is determined
Obtain decoded result to be exported, target decoder algorithm is updated according to the feedback information that user inputs.
Optionally, when exporting decoded result, identifier is added first for wireless network name corresponding to target code.So
Afterwards, when user clicks on identifier, output plays frame, plays the feedback information that frame is used to show decoded result and receive user's input.
Wherein, identifier can be newly-increased prompting icon in list item corresponding to target code in wireless network list, should
Network name in the icon representation list item is to be confirmed.Bullet frame, including the SSID obtained according to default decoding algorithm, and for
The correct button and wrong button of family input feedback information.If user clicks on correct button, triggering confirms instruction.If with
Wrong button is clicked at family, then instruction is changed in triggering.
Further, as shown in Fig. 2 SSID that default decoding algorithm obtains can be exported in frame is played and using other solutions
The SSID that code algorithm obtains.Decoding algorithm corresponding to the SSID that user is clicked on is defined as target decoder algorithm.As shown in Fig. 2
The SSID obtained using default decoding algorithm is network D, and the SSID obtained using other decoding algorithms is network D-1.User's point
Hit wherein any one when, triggering confirm instruction.Decoding algorithm is defined as used by terminal will confirm that the SSID that instruction is pointed to
Target decoder algorithm.
User can be determined correct when requiring connect to the wireless network of some AP offers by AP supplier
SSID.Such as the WiFi titles in its family of inquiry householder, or the WiFi titles of inquiry waiter retail shop.If wireless network arranges
The SSID that user finds is not present in table, then user can click on the identifier in wireless network list, and then trigger and play frame, and defeated
Enter feedback command.
Because user knows its SSID found, thus the feedback message inputted according to user can determine that it is currently used pre-
If whether decoding algorithm is correct.If incorrect use other decoding processes instead, and will use what other decoding processes obtained
Decoded result is exported, then obtains the feedback information of user's input, and determines target decoder algorithm according to feedback information.
Optionally, if user's input validation instructs, default decoding algorithm is defined as target decoder algorithm.If with
Instruction is changed in family input, then other decoding algorithms is defined as into target decoder algorithm, other decoding algorithms are the first decoding algorithm
With the decoding algorithm in the second decoding algorithm in addition to default decoding algorithm.
In another implementation, if non-Chinese characters in common use in decoded result be present, other decoding algorithms pair are used
Target code is decoded.If non-Chinese characters in common use are not present in the decoded result obtained using other decoding algorithms, by it
His decoding algorithm is defined as target decoder algorithm.
The decoding algorithm that the embodiment of the present application provides determines method, first determines whether target code meets the first decoding calculation
Method and the second decoding algorithm；If target code meets the first decoding algorithm and the second decoding algorithm, calculated according to the first decoding
Method obtains the valid data position of target code；Target decoder algorithm is determined according to valid data.Relative to being used in correlation technique
Default algorithm or using fixed decoding algorithm, the application can meet the first decoding algorithm and the judging target code
During two decoding algorithms, the valid data position in target code is obtained, and the valid data position for giving acquisition determines target
Decoding algorithm, and then quick determination target decoder algorithm, improve SSID decoding efficiencies.

Wifi lists, as shown in figure 3, including：
Step 210, mobile phone around searching after AP, judge coding corresponding to AP SSID whether UTF-8 decoding algorithms
With GBK decoding algorithms.
Specifically, judge whether to meet the requirement of UTF-8 bytes number and whether meet GBK coding span requirements.
If step 220, meeting UTF-8 decoding algorithms, GBK decoding algorithms are not met, then judge that current SSID belongs to
UTF-8 is encoded, and the physical address of the AP is added in UTF-8 the encoding lists.
In the present embodiment, UTF-8 and AP relation list can be established, wherein preserving the physics for the AP for meeting UTF-8
Address.
If step 230, not meeting UTF-8 decoding algorithms, meet GBK decoding algorithms, then judge that current SSID belongs to
UTF-8 is encoded, and the MAC of AP address is added in the list of GBK codings.
In the present embodiment, GBK and AP relation list can be established, wherein preserving the physical address for the AP for meeting GBK.
If step 240, do not meet UTF-8 decoding algorithms and do not meet GBK decoding algorithms yet, according to default decoding process
Decoded.Default decoding process can be that the first decoding algorithm can also be the second decoding algorithm.
If step 250, meeting UTF-8 decoding algorithms and also complying with GBK decoding algorithms, mesh is obtained according to the first decoding algorithm
