301st, terminal to server sends download request, the download request carried terminal positional information.

In embodiments of the present invention, terminal has the function of connection access point.Terminal can send to server Download request, the access-in point information of same geographic area is located to be obtained from server with terminal positional information And corresponding password.Terminal can periodically send download request, or terminal is detecting triggering bar Download request is sent during part, the embodiment of the present invention is not especially limited to this.Wherein, trigger condition can be When terminal is in network connection state, or for terminal detects the trigger action that data are downloaded, or it is end End detects access point attended operation, and the embodiment of the present invention is not especially limited to this.

302nd, server obtains data to be sent after the download request for receiving terminal, and this is to be sent Data is activation to terminal, the data to be sent include being located at same geographic area with terminal positional information Access-in point information and corresponding password, 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 detected to any access The attended operation of point, terminal can obtain request to the password of server hair access point, be connect according to this by server The access-in point information of access point returns to the password of the access point, and terminal connects the access point according to the password for receiving. But, based on some reason (data networks of such as, terminal data flow deficiency, or terminal position Network dtr signal etc.), terminal cannot connection server, and then access point cannot be connected.

In embodiments of the present invention, server can store substantial amounts of access-in point information and corresponding password, example Such as access-in point information of WiFi access points and corresponding WiFi passwords.In order that terminal is in arbitrary network Under state, the password of access point particularly can be got under non-network connection status, and then be connected to access , to reach the purpose of online, server can be according to the download request of terminal, and the data that will store (including connect for point Access point information and corresponding password) send to terminal so that the data storage that terminal will can be received is Offline database, and the password of access point just can be directly obtained by offline database.

Further, it is contemplated that the memory capacity of terminal is limited, in order to improve the utilization rate of terminal storage space, Ensure that terminal connects the success rate of access point simultaneously, server can be according to default screening conditions, in connecing for storage In access point information and corresponding password, filter out a part and be worth access point letter higher for a user Breath, afterwards, obtains from the data for filtering out and is located at the to be sent of same geographic area with terminal positional information Data, and by data is activation to be sent to terminal.

Wherein, because the scope of activities of user is usually fixed, server is sieved in the data to storing When selecting, can be screened according to geographic area, to reduce the scope of follow-up further screening, be improved screening effect Rate, specific screening process can be divided into following several situations：

The first situation：Obtain and number of times is requested in the same geographic area more than the of the first predetermined threshold value One access-in point information and corresponding password, according to geographic area to the first access-in point information for getting and Corresponding password carries out packet storage.

Wherein, the first predetermined threshold value can as needed be pre-set or be changed by server, the present invention Embodiment is not especially limited to this.

It should be noted that for any access-in point information of server storage, server is receiving terminal When password to the access point obtains request, can the corresponding record requested number of times of the access-in point information.To be asked The reason for asking number of times more than the first predetermined threshold value as screening conditions is that the requested number of times is reflected and accordingly connect The connected number of times of access point, correspondingly, the corresponding requested number of times of the access-in point information is higher, illustrates terminal The probability for connecting corresponding access point is higher, that is to say, the access point is worth higher for user.Therefore, Screened by the way that terminal is connected into probability access-in point information high, disclosure satisfy that the connection of end-on access point Demand, while avoiding the waste of terminal storage space.

Wherein, requested number of times can also be the requested number of times in preset time period, and the preset time period can Pre-set according to demand by server or changed, the preset time period can be 1 day, 1 week, 1 month Deng the embodiment of the present invention is not especially limited to this.Due to access point be connected situation may with when Between being continually changing, than if any access point at least 10 terminals connections daily within a period of time, and can Subsequently no terminal can be caused to connect the access point because businessman closes, therefore by counting Preset Time Connected number of times in section so that the data for screening can more meet the actual connection of access point, carry The accuracy of screening high, it is ensured that terminal connects the success rate of access point.

Second situation：Obtain positioned at data network signals intensity in same geographic area less than the second default threshold Second access-in point information and corresponding password of value, believe the second access point for getting according to geographic area Breath and corresponding password carry out packet storage.

Wherein, the second predetermined threshold value can as needed be pre-set or be changed by server, the present invention Embodiment is not especially limited to this.

It should be noted that for any access-in point information of server storage, server can also be to that should connect The data network signals intensity of access point information record terminal.Specifically, the access that terminal can be near searching During point, the access-in point information and the data network signals intensity of itself for searching are reported to server, by taking The business device corresponding access-in point information of correspondence records the data signal strength.Wherein, the data network signals of record When weaker, network cannot be connected when illustrating terminal near the access point, now, terminal needs connection, and this connects The possibility of access point is bigger, that is to say, the valency for user of the weaker corresponding access point of data network signals Value is higher.Therefore, screened by by the weaker access-in point information of data network signals, disclosure satisfy that end The connection requirement to access point is held, while avoiding the waste of terminal storage space.

The third situation：Screened with reference to above-mentioned the first situation and second situation so that filter out Data can either cover connected number of times access-in point information higher, and it is weaker to cover data network signals again Access-in point information, expand the coverage of the selection result, can further improve terminal connection access The success rate of point.

It should be noted that above-mentioned geographic area can be divided according to administrative region, such as, according to difference City divide etc.；Or divided according to other region division modes, the embodiment of the present invention is to this It is not especially limited.Specifically, for any access-in point information of server storage, server can be corresponded to The positional information of the access point is stored, the positional information of the access point can be by server in user (such as businessman) Obtained during registration access-in point information；Or the positional information of itself is reported when access point is connected by terminal, take The positional information of terminal to report is stored as business device the positional information of the access point.Server can be according to access Point positional information determine it where geographic area.

It should be noted that because the access-in point information and corresponding password of server storage can update, For example, the record of new access-in point information and correspondence password is increased, or access-in point information is changed, The SSID of such as access point is changed, or the password of access point occurs change etc., and server can be according to reality The situation of change on border, is performed a plurality of times the process of screening, to ensure the accuracy of the data for filtering out.For every The data that primary screening goes out, server can be its interpolation data according to the geographic area belonging to the data Version so that terminal can be updated according to version to local data.For example, when geographic area is Beijing, The version of the data that server meets above-mentioned screening conditions in the Beijing Area that filters out for the first time is Bj-version1, meets the version of the data of above-mentioned screening conditions in the Beijing Area that server programmed screening goes out It is bj-version2 etc. so that when the version of terminal local data is bj-version1, can be obtained from server The data that version is bj-version2 are taken to be updated.

In embodiments of the present invention, in order to ensure the security of data, the number to be sent that server gets According to can be to be encrypted the ciphertext for obtaining to access-in point information and corresponding password.Specifically, server exists Get with terminal positional information after the access-in point information and corresponding password of same geographic area, according to First AES, the SSID and BSSID included to access point packet is encrypted, and obtains access point letter Breath ciphertext；According to the 3rd AES, pair password corresponding with access-in point information is encrypted, and obtains and connects The corresponding Crypted password of access point information ciphertext.Further, since the memory space that the ciphertext after encryption takes is less than The memory space that plaintext before encryption takes, therefore, can also further be reduced by encryption to be sent The memory space that data take in terminal, and then improve the memory space utilization rate of terminal.

Wherein, the first AES and the 3rd AES can be the same or different.Due to connecting in terminal When connecing access point, to the representation of access-in point information be in plain text or ciphertext is not required, and is connected in terminal When connecing access point, the plaintext of clear and definite password is needed, therefore, the actual demand of access point is connected with reference to terminal, together When further strengthen the security of data, it is preferable that the first AES is irreversible encryption algorithm, the Three AESs are irreversible cryptographic algorithm.

When the first AES is irreversible encryption algorithm, first AES can be hash algorithm, phase Ying Di, the process that the SSID and BSSID included to access point packet are encrypted can be：Calculate SSID Cryptographic Hash and BSSID cryptographic Hash；The cryptographic Hash of SSID is combined with the cryptographic Hash of BSSID, Obtain access-in point information ciphertext.Wherein, the cryptographic Hash of SSID is combined with the cryptographic Hash of BSSID, Can be the simple concatenation of the cryptographic Hash with the cryptographic Hash of BSSID of SSID, for the sequencing of the two, The embodiment of the present invention is not especially limited.Additionally, the first AES can also be in addition to hash algorithm Other irreversible AESs, the embodiment of the present invention is not especially limited to this.

When the 3rd AES is reversible AES, the 3rd AES can be calculated for XXTea is encrypted Method or other reversible AESs, the embodiment of the present invention are not especially limited to this.

303rd, the data storage is offline database after the data for receiving server transmission by terminal.

In embodiments of the present invention, because the access-in point information and corresponding password of server storage may Real-time update, for the real-time of data in the offline database for ensureing terminal, terminal can also be to off-line data Storehouse is updated, and specific update mode includes following several situations：

The first situation：Terminal obtains the data of latest edition from server, and the data of the latest edition are deposited It is offline database to store up.

Specifically, when terminal detects the trigger action for updating offline database, data are sent to server Request is updated, the data update carried terminal positional information in request, are believed according to the terminal location by server Breath, obtains and returns the data of the latest edition that same geographic area is located at the terminal positional information.Terminal After receiving the data of the latest edition, original offline database is deleted, the data of the latest edition are deposited It is offline database to store up.

Second situation：What terminal did not included from the server local offline database of acquisition updates the data, will This updates the data and is inserted into local offline database.

Specifically, when terminal detects the trigger action for updating offline database, data are sent to server Request is updated, the data update request carried terminal positional information and terminal current version, by server root According to the terminal positional information and terminal current version, acquisition is updated the data.It refers to latest edition that this is updated the data Has discrepant access-in point information and corresponding close between this data and the data of the terminal current version Code.Afterwards, updated the data according to this, offline database is updated, detailed process can be：

Whether the access-in point information that each included in for updating the data updates, judges deposited in offline database In the access-in point information of the renewal；If it does not exist, then the access-in point information of the renewal and correspondence are updated Password be added in offline database.If it is present first deleting connecing for the renewal from offline database The corresponding record of access point information, the password addition for then again updating the access-in point information of the renewal and correspondence To in offline database.

It should be noted that above-mentioned the first situation and second situation, terminal can also according to predetermined period, Periodically offline database is updated, the predetermined period can be pre-set or be changed by server； Or, when server has redaction to update, remind terminal to carry out renewal of offline database etc., the present invention Embodiment is not especially limited to the opportunity that terminal carries out offline database renewal.

If it should be noted that in preset duration, being not detected by updating the trigger action of offline database, Then terminal can also be updated to offline database automatically.Specifically, when terminal detect already exceed it is default When duration is not updated to offline database, local offline database is deleted.Afterwards, from trend server Download request is sent, the data of latest edition are reacquired from server, and by the data storage of latest edition It is offline database.Preset duration can be preset by server, when offline database exceedes to be preset When length does not update, illustrate that the data of the offline database are expired, it is impossible to meet the company of end-on access point Connect demand.Wherein, the opportunity that terminal obtains the data of latest edition from server can be to delete local offline Obtained during database, or the attended operation of access point is detected after the local offline database of terminal deletion When obtain etc., the embodiment of the present invention is not especially limited to this.

It should be noted that database of the offline database of terminal local for key-value types, uses The database of key-value types can improve efficiency data query, while improving the utilization rate of terminal storage space.

In embodiments of the present invention, terminal has been after offline database has been locally stored, using offline database, The password of access point is obtained, and then carries out the connection of access point, detailed process is referring to following step 304 to step Rapid 306.

304th, when terminal detects the attended operation to target access, target access information, mesh are determined Mark access-in point information is used to identify target access.

In embodiments of the present invention, terminal can be scanned for neighbouring access point, for connecing for searching Access point, terminal can obtain the access-in point information of the access point, that is to say, terminal can get the access point SSID and BSSID, and show the access-in point information.In the access point for searching, when terminal is detected During to the attended operation of target access, terminal can determine that the target access information of target access, namely It is the SSID and BSSID of target access.

305th, terminal obtains target close according to target access information from locally stored offline database Code, the target password is the password matched with access-in point information.

In embodiments of the present invention, according to access-in point information in offline database and the not similar shape of correspondence password Formula, the process for obtaining target password 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 correspondence password, eventually Holding the process for obtaining target password can be：Terminal searches offline number according to the target access information for obtaining Whether the target access information is included according in storehouse；If comprising, obtain with the target access information pair The password answered, target password is defined as by the password of acquisition.If do not included, return and obtain failed message.

Second situation：The access-in point information and correspondence password stored in offline database are by server The ciphertext for obtaining is encrypted, be that is to say, off-line data library storage is access-in point information ciphertext and correspondence Crypted password, then terminal obtain target password process as shown in Figure 3 B, comprise the following steps：

Step 1：Terminal-pair target access information is encrypted, and obtains target access information ciphertext.

Step 2：Whether target access information ciphertext is included in terminal judges offline database.

Step 3：If comprising terminal then obtains corresponding with target access information ciphertext from offline database Crypted password.

Step 4：The Crypted password that terminal will get is decrypted, and obtains target password.

Step 5：If do not included, return and obtain failed message.

Wherein, terminal need to use with server identical AES, target access information is encrypted, To obtain target access information ciphertext, detailed process can be：According to the first AES, SSID is calculated Cryptographic Hash and BSSID cryptographic Hash；The cryptographic Hash of SSID is combined with the cryptographic Hash of BSSID, Obtain access point ciphertext.The process that be combined for the cryptographic Hash of the cryptographic Hash of SSID and BSSID by terminal, The process for being combined the cryptographic Hash of the cryptographic Hash of SSID and BSSID with server similarly, herein no longer Repeat.Wherein, terminal need to be solved using decipherment algorithm corresponding with server for encrypting algorithm to Crypted password It is close, to obtain target password.

In another embodiment, terminal can also independently update offline database.If terminal does not get target Password, that is to say, the password not being stored with offline database with the target access information matches, then eventually End can obtain corresponding password from server, so according to the target access information and get it is close Code is updated to offline database.Specifically, if terminal is in non-network when not getting target password Connection status, then terminal the target access information can be recorded, treat terminal be in network connection state When, the target access information is sent to server, target access information correspondence is returned to by server Password；Terminal is updated according to the target access information and the password for getting to off-line data. If terminal can be obtained directly in network connection state, terminal when not getting target password from server Corresponding password, and then offline database is updated.Offline database is independently updated by terminal, is carried The high flexibility for updating offline database.

Below by offline database store be access-in point information and correspondence password ciphertext as a example by, to end The autonomous process for updating offline database in end is explained, and as shown in Figure 3 C, is comprised the following steps：

Step 1：The SSID and BSSID that terminal includes target access information are encrypted, and obtain mesh Mark access-in point information ciphertext.
