301, terminal to server, which is sent, downloads request, which asks carried terminal location information.
In embodiments of the present invention, terminal has the function of connecting access point.Terminal can send to download to server and ask It asks, to be located at the access-in point information of same geographic area and corresponding password with terminal positional information from server acquisition. Terminal can periodically send download request or terminal sends download request when detecting trigger condition, and the present invention is real Example is applied to be not especially limited this.Wherein, it when trigger condition can be that terminal is in network connection state, or is detected for terminal The trigger action downloaded to data, or detect that access point attended operation, the embodiment of the present invention are not made this specifically for terminal It limits.
302, server obtains data to be sent, by the data to be sent after the download request for receiving terminal It is sent to terminal, which includes being located at the access-in point information of same geographic area and right with terminal positional information The password answered, access-in point information include the SSID and BSSID of access point.
In the prior art, usually when terminal is in network connection state, if detecting the company to any access point Operation is connect, the password that terminal can send out access point to server obtains request, by server according to the access-in point information of the access point The password of the access point is returned to, terminal connects the access point according to the password received.But based on some reasons (for example, eventually The data network signals of end data underfed or terminal position are poor etc.), terminal can not Connection Service device, in turn Access point can not be connected.
In embodiments of the present invention, server can store a large amount of access-in point information and corresponding password, such as WiFi The access-in point information of access point and corresponding WiFi passwords etc..Especially it is non-net to make terminal under arbitrary network state The password of access point can be got under network connection status, and then is connected to access point to achieve the purpose that online, server can It is asked according to the download of terminal, the data (including access-in point information and corresponding password) of storage is sent to terminal so that The data received can be stored as offline database by terminal, and directly can obtain access point by offline database Password.
Further, it is contemplated that the memory capacity of terminal is limited, in order to improve the utilization rate of terminal storage space, protects simultaneously The success rate of terminal connection access point is demonstrate,proved, server can be according to default screening conditions, in the access-in point information and correspondence of storage Password in, filter out a part be worth higher access-in point information for a user, later, obtained from the data filtered out The data to be sent for being located at same geographic area with terminal positional information are taken, and data to be sent are sent to terminal.
Wherein, since the scope of activities of user is usually fixed, server, can when the data to storage are screened It is screened according to geographic area, to reduce the range subsequently further screened, improves screening efficiency, specific screening process can To be divided into following several situations：
The first situation：Obtain the first access for being located at and being requested that number is more than the first predetermined threshold value in same geographic area Point information and corresponding password, divide the first access-in point information got and corresponding password according to geographic area Group storage.
Wherein, the first predetermined threshold value can be pre-set or changed as needed by server, the embodiment of the present invention This is not especially limited.
It should be noted that for any access-in point information of server storage, receiving terminal-pair, this connects server It, can the requested number of the corresponding record access-in point information when password of access point obtains request.It is more than first pre- by requested number If threshold value is as the reason of screening conditions, which reflects the corresponding connected number of access point, correspondingly, should The corresponding requested number of access-in point information is higher, illustrate terminal connect corresponding access point probability it is higher, that is to say, the access Point is worth higher for users.Therefore, it is screened by the way that terminal is connected the high access-in point information of probability, disclosure satisfy that end The connection requirement to access point is held, while avoiding the waste of terminal storage space.
Wherein, it can be requested number within a preset period of time to be requested number also, which can be by servicing Device is pre-set or is changed according to demand, which can be 1 day, 1 week, 1 month etc., and the embodiment of the present invention is to this It is not especially limited.Since the connected situation of access point may constantly change with the time, than if any access point exist At least 10 terminal connections daily in a period of time, and may be closed due to businessman causes not having subsequently terminal connection should Access point, therefore by counting the connected number in preset time period so that the data screened can more meet access point Practical connection, improve the accuracy of screening, ensure that terminal connection access point success rate.
The second situation：It obtains and is located at data network signals intensity in same geographic area and is less than the of the second predetermined threshold value Two access-in point informations and corresponding password, according to geographic area to the second access-in point information got and corresponding password It is grouped storage.
Wherein, the second predetermined threshold value can be pre-set or changed as needed by server, the embodiment of the present invention This is not especially limited.
It should be noted that for any access-in point information of server storage, server can also correspond to access point letter The data network signals intensity of breath record terminal.Specifically, terminal can be reported when searching neighbouring access point to server The access-in point information searched and the data network signals intensity of itself correspond to corresponding access-in point information by server and record The data signal strength.Wherein, it when the data network signals of record are weaker, can not be connected when illustrating terminal near the access point Network that is to say at this point, terminal needs the possibility for connecting the access point bigger, the weaker corresponding access of data network signals The value for users of point is higher.Therefore, by screening the weaker access-in point information of data network signals, Neng Gouman The connection requirement of sufficient end-on access point, while avoiding the waste of terminal storage space.
The third situation：It is screened in conjunction with the first above-mentioned situation and the second situation so that the data filtered out were both The higher access-in point information of connected number can be covered, and the weaker access-in point information of data network signals can be covered, is expanded The big coverage area of the selection result, can be further improved the success rate of terminal connection access point.
It should be noted that above-mentioned geographic area can be divided according to administrative region, for example, according to different cities into Row division etc.；Or divided according to other region division modes, the embodiment of the present invention is not especially limited this.Specifically Ground, for any access-in point information of server storage, server can correspond to the location information for storing the access point, the access The location information of point can be obtained by server when user (such as businessman) registers access-in point information；Or it is connect in connection by terminal Report the location information of itself, server that the location information that terminal reports is stored as to the location information of the access point when access point. Server can determine the geographic area where it according to the location information of access point.
It should be noted that since the access-in point information of server storage and corresponding password can update, for example, The record or access-in point information for increasing new access-in point information and corresponding password are changed, such as access point SSID is changed or change etc. occurs for the password of access point, and sieve can be performed a plurality of times according to actual situation of change in server The process of choosing, to ensure the accuracy of the data filtered out.For the data filtered out each time, server can be according to the number It is the version of its interpolation data so that terminal can be updated local data according to version according to affiliated geographic area.Example Such as, when geographic area is Beijing, the version of the data of above-mentioned screening conditions is met in the Beijing Area that server filters out for the first time This is bj-version1, and the version for the data for meeting above-mentioned screening conditions in the Beijing Area that server programmed screening goes out is Bj-version2 etc. so that when the version of terminal local data is bj-version1, it is bj- that version can be obtained from server The data of version2 are updated.
In embodiments of the present invention, in order to ensure that the safety of data, the data to be sent that server is got can be The ciphertext that access-in point information and corresponding password are encrypted.Specifically, server is being got and terminal location Information is after the access-in point information and corresponding password of same geographic area, according to the first Encryption Algorithm, to access-in point information Including SSID and BSSID be encrypted, obtain access-in point information ciphertext；According to third Encryption Algorithm, pair and access-in point information Corresponding password is encrypted, and obtains Crypted password corresponding with access-in point information ciphertext.Further, since encrypted ciphertext accounts for Memory space is less than the memory space that plaintext before encrypting occupies, and therefore, can also further be reduced and be waited for by encryption The memory space that the data of transmission are occupied in terminal, and then improve the memory space utilization rate of terminal.
Wherein, the first Encryption Algorithm and third Encryption Algorithm can be the same or different.It is accessed due to being connected in terminal When point, the representation to access-in point information is in plain text or ciphertext does not require, and when terminal connects access point, it need to define Therefore the plaintext of password connects the actual demand of access point in conjunction with terminal, while further reinforcing the safety of data, excellent Selection of land, the first Encryption Algorithm are irreversible encryption algorithm, and third Encryption Algorithm is irreversible cryptographic algorithm.
When the first Encryption Algorithm is irreversible encryption algorithm, which can be hash algorithm, correspondingly, right The process that the SSID and BSSID that access-in point information includes are encrypted can be：Calculate the cryptographic Hash of SSID and the Kazakhstan of BSSID Uncommon value；The cryptographic Hash of the cryptographic Hash of SSID and BSSID is combined, access-in point information ciphertext is obtained.Wherein, by the Kazakhstan of SSID Uncommon value and the cryptographic Hash of BSSID are combined, and can be the simple concatenation of the cryptographic Hash of the cryptographic Hash and BSSID of SSID, for The sequencing of the two, the embodiment of the present invention are not especially limited.In addition, the first Encryption Algorithm can also be in addition to hash algorithm it Other outer irreversible Encryption Algorithm, the embodiment of the present invention are not especially limited this.
When third Encryption Algorithm be reversible Encryption Algorithm when, the third Encryption Algorithm can be XXTea Encryption Algorithm or its Its reversible Encryption Algorithm, the embodiment of the present invention are not especially limited this.
303, the data are stored as offline database by terminal after the data for receiving server transmission.
In embodiments of the present invention, since the access-in point information of server storage and corresponding password may in real time more Newly, in the offline database in order to ensure terminal data real-time, terminal can also be updated offline database, specifically more New paragon includes following several situations：
The first situation：Terminal from server obtain latest edition data, by the data of the latest edition be stored as from Line database.
Specifically, it when terminal detects the trigger action of update offline database, is asked to the update of server transmission data It asks, carried terminal location information in data update request, by server according to the terminal positional information, obtains and return and be somebody's turn to do Terminal positional information is located at the data of the latest edition of same geographic area.After terminal receives the data of the latest edition, delete Except original offline database, the data of the latest edition are stored as offline database.
The second situation：What terminal did not included from the local offline database of server acquisition updates the data, by the update Data are inserted into local offline database.
Specifically, it when terminal detects the trigger action of update offline database, is asked to the update of server transmission data It asks, which asks carried terminal location information and terminal current version, by server according to the terminal positional information And terminal current version, acquisition update the data.This update the data refer to latest edition data and the terminal current version Have discrepant access-in point information and corresponding password between data.Later, updated the data according to this, to offline database into Row update, detailed process can be：
For each of including newer access-in point information in updating the data, judge in offline database with the presence or absence of this more New access-in point information；If it does not exist, then the newer access-in point information and corresponding newer password are added to offline In database.If it is present first deleting the corresponding record of the newer access-in point information from offline database, then again will The newer access-in point information and corresponding newer password are added in offline database.
It should be noted that the first above-mentioned situation and the second situation, terminal can also be according to predetermined period, periodically Offline database is updated, which can be pre-set or be changed by server；Alternatively, when server has newly When version updating, terminal is reminded to carry out the update etc. of offline database, the embodiment of the present invention carries out offline database more to terminal New opportunity is not especially limited.
It should be noted that if in preset duration, the trigger action of update offline database is not detected, then terminal Also offline database can be updated automatically.Specifically, preset duration is alreadyd exceed not to off-line data when terminal detects When library is updated, local offline database is deleted.Later, it is sent from trend server and downloads request, obtained again from server The data of latest edition are taken, and the data of latest edition are stored as offline database.Preset duration can be carried out pre- by server It first sets, when offline database does not update more than preset duration, illustrates that the data of the offline database are expired, Wu Faman The connection requirement of sufficient end-on access point.Wherein, the opportunity that terminal obtains the data of latest edition from server can be to delete It is obtained when local offline database, or when detecting the attended operation of access point after the offline database of terminal deletion local Obtain etc., the embodiment of the present invention is not especially limited this.
It should be noted that the offline database of terminal local is the database of key-value types, using key-value The database of type can improve efficiency data query, while improve the utilization rate of terminal storage space.
In embodiments of the present invention, terminal is after being locally stored offline database, and using offline database, acquisition connects The password of access point, and then the connection of access point is carried out, detailed process is referring to following step 304 to step 306.
304, when terminal detects the attended operation to target access, target access information, target access are determined Point information is for identifying target access.
In embodiments of the present invention, terminal can scan for neighbouring access point, for the access point searched, eventually End can obtain the access-in point information of the access point, that is to say, terminal can get the SSID and BSSID of the access point, and show Show the access-in point information.In the access point searched, when terminal detects the attended operation to target access, terminal can The target access information for determining target access that is to say the SSID and BSSID of target access.
305, terminal obtains target password according to target access information from locally stored offline database, should Target password be and the matched password of access-in point information.
In embodiments of the present invention, it according to the different form of access-in point information in offline database and corresponding password, obtains Take the process of target password that can be divided into the following two kinds situation：
The first situation：What is stored in offline database is the plaintext of access-in point information and corresponding password, and terminal obtains The process of target password can be：For terminal whether according to the target access information of acquisition, it includes to be somebody's turn to do to search in offline database Target access information；If including obtaining password corresponding with the target access information, the password of acquisition is determined as Target password.If do not included, acquisition failed message is returned.
The second situation：The access-in point information and corresponding password stored in offline database is to be added by server Close obtained ciphertext, that is to say, off-line data library storage is access-in point information ciphertext and corresponding Crypted password, then terminal The process for obtaining target password is as shown in Figure 3B, includes the following steps：
Step 1：Terminal-pair target access information is encrypted, and obtains target access information ciphertext.
Step 2：Whether terminal judges in offline database to include target access information ciphertext.
Step 3：If including encryption corresponding with target access information ciphertext is obtained if terminal from offline database Password.
Step 4：The Crypted password got is decrypted terminal, obtains target password.
Step 5：If do not included, acquisition failed message is returned.
