Fig. 4-1 is the flow chart of another wireless local area network access method shown according to an exemplary embodiment, can be with For implementation environment as shown in Figure 1, comprising:

Step 401, terminal obtain access information, which includes the mark of each access point of terminal surrounding.

When terminal does not access WLAN, network acquisition instruction, the network acquisition instruction first can be received by terminal It can be by user's triggering.Illustratively, user can when needing to connect Wireless LAN operating terminal, triggering terminal Generate network acquisition instruction；Alternatively, terminal can also obtain network acquisition instruction in booting automatically.

Access point can continue to broadcast the facility information of itself, for example, wireless router facility information may include SSID and The address MAC (media access control, Media Access Control).Terminal, can be with after obtaining network acquisition instruction According to network acquisition instruction come access point searching, terminal may search for the facility information of neighbouring access point broadcast.It needs to illustrate , each terminal have one it is preset can scanning range, therefore, " surrounding " described in the disclosure refers to that the terminal can be swept It retouches in range.

It should be noted that in the embodiments of the present disclosure, the mark of access point can in SSID and MAC Address at least One kind, the mark of the access point plays the role of being identified access point differentiation, in practical application, since SSID is alterable , in the SSID variation of access point, if network server record has the SSID before access point variation, can by terminal or Access point notifies the network server.Since MAC Address is usually unique constant, there can be criterion using MAC Address Know access point, in practical application, SSID can also be added to identify access point using MAC Address.

Assuming that the access point is wireless router, in the related technology, SSID41 that terminal broadcasts access point and corresponding Signal strength 42 is shown to user in user interface, and as shown in the Fig. 4-2, by user, therefrom selection target SSID, terminal connection are somebody's turn to do The corresponding wireless router of target SSID.But since target SSID is selected by user, safety or signal stabilization Property it is poor, cause access WLAN good service can not be provided, it may be necessary to user's frequent switching provide service Wireless router, therefore, the efficiency for accessing WLAN is poor.

In the embodiment of the present disclosure, access point identity can be obtained by the facility information of scanning access point broadcast, such as SSID, without showing user interface as shown in the Fig. 4-2.

Step 402, terminal send access information to network server.

In practical application, the access information that terminal can directly will acquire is sent to network server, can also be according to adding Confidential information obtains new access information to the further screening of access information progress and is then forwarded to network server.

Exemplary, Fig. 4-3 is that a kind of terminal shown according to an exemplary embodiment is believed to network server transmission access The method flow diagram of breath, comprising:

Step 4021, terminal are indicated according to the encryption of each access point, and each access point is divided into encryption access point set It closes and non-encrypted access point set, the encryption accesses point set and be used for recording of encrypted access point, which uses In recording non-encrypted access point, encryption instruction is used to indicate whether access point encrypts.

In practical application, access point can carry encryption information in the facility information of broadcast, which includes: adding Close instruction.Terminal can extract encryption instruction in the encryption information, when establishing connection with encryption access point, need to carry phase The password answered, and when establishing connection with non-encrypted access point, then without carrying password.

It is exemplary, it is assumed that as shown in table 1, terminal scanning to 4 access points around, mark be respectively " CMCC ", " 123 ", " CMCC-WEB " and " ABC " are indicated according to encryption, it is recognised that access point " CMCC " and " 123 " encryption, access point Therefore access point " CMCC " and " 123 " encryption can be divided to encryption access point set by " CMCC-WEB " and " ABC " unencryption It closes, access point " CMCC-WEB " and " ABC " are divided to non-encrypted access point set.In practical application, encryption instruction can be used Binary-coded character indicates that such as " 0 " represents encryption, and " 1 " represent unencryption.

Table 1

The mark of access point	Encryption instruction
		CMCC	Encryption
123	Encryption
		CMCC-WEB	Unencryption
ABC	Unencryption

Whether recording of encrypted accesses the access point in point set in the preset access point cipher table of step 4022, terminal inquiry Password.

Since, when connecting the WLAN that some encryption access points provide, user can input corresponding close before terminal These passwords can be recorded in access point cipher table by code, terminal, so that terminal accesses corresponding encryption access point in next time When the WLAN of offer, password is inputted without user.

Terminal can inquire in the preset access point cipher table whether access point in recording of encrypted access point set Password, if in access point cipher table recording of encrypted access point set in access point password, the encryption access point for A non-encrypted access point is equivalent to for terminal.

Step 4023, when in preset access point cipher table record have encryption access point set in any access point it is close Any access point is determined as access point to be selected by code, terminal.

It is exemplary, it is assumed that record has the close of the access point " 123 " for being divided to encryption access point set in access point cipher table Code, then the access point " 123 " is determined as access point to be selected by terminal.

Step 4024, terminal update access information, and making updated access information includes: connecing in alternative access point set The mark of access point, it includes: the access point in access point to be selected and non-encrypted access point set that this, which alternatively accesses point set,.

It is exemplary, it is assumed that access point to be selected is access point " 123 ", and non-encrypted access point set record has access point " CMCC- WEB " and " ABC ", then updated access information includes the mark of access point " 123 ", " CMCC-WEB " and " ABC ".

It should be noted that when determining that non-recording of encrypted accesses point set in preset access point cipher table in step 4022 In access point password, then alternatively access point set in access point to be selected be 0.

Step 4025, terminal send updated access information to network server.

In the embodiment of the present disclosure, terminal, may nothings by some terminals by according to encryption instruction and access point cipher table Method establishes the access point deletion of connection, reduces the access point number that network server is ranked up, to reduce network clothes The computational load of business device, avoids the unnecessary wasting of resources.

In practical application, due to the weak access point potential range terminal of signal strength distance farther out, can not be mentioned to terminal For good network service, these access points can be weeded out, such as terminal can be according to each access point scanned Signal strength is ranked up each access point, and then the mark of the access point of the predetermined number by sequence earlier above passes through access letter Breath is reported to network server, and others are rejected, to reduce the computational load of network server, avoids unnecessary resource Waste.

Step 403, network server sort each access point according to access information to obtain access priority list.

The access priority list records access priority of each access point.Network server receives what terminal was sent It, can be by determining the access priority of each access point with pre-set access-in point information table after access information, it can also be with The access priority of each access point is calculated according to the parameters carried in access information, the disclosure illustratively provides Mode can be achieved as follows:

Can be in realization mode at the first, webserver storage has access-in point information table, and access-in point information table has recorded The mark and switching performance information of the access point of the network server management, switching performance information include: safety, connectivity and steady It is at least one of qualitative, wherein safety is used to assess the security performance of access point, and the higher access point of safety is not allowed more Rogue attacks are subject to, the probability for revealing privacy of user is lower；Connectivity is used to characterize the quality of connection of access point, connectivity Stronger access point, connectivity is higher, and the Connection Time is shorter, and the information interactive process for establishing connection is fewer；Stability is used After characterization terminal and access point establish connection, the stability of access point offer service, the stronger access point of stability, Network speed is faster, and the connection with terminal is less susceptible to break.

Correspondingly, shown in Fig. 4-4, Fig. 4-4 be it is shown according to an exemplary embodiment it is a kind of according to access information to each A access point sorts to obtain the method flow diagram of access priority list, comprising:

Step 4031a, network server inquires access-in point information table, obtains each connect according to the mark of each access point The corresponding switching performance information of access point.

In the embodiment of the present disclosure, the access-in point information table that is stored in network server can according to each terminal with access Point establishes connection procedure (after the WLAN that scanning and access point including access point provide establishes connection and establishes connection Preset time period in) in be reported to what the information of network server generated, be also possible to pre-set, can also be basis What the information that the access point of the network server management uploads in real time or the period uploads generated, wherein the network server pipe The access point of reason can be the pre-registered access point in the network server, usually the safety of its WLAN provided Property is higher.

It is exemplary, it is assumed that the pre-stored access-in point information table of network server is as shown in table 2, it is assumed that the link information table The switching performance information of middle record includes: safety, connectivity and stability, can also include according to preset algorithm (as weighted Average algorithm or average algorithm) according to the comprehensive performance of safety, connectivity and stable calculation, it as shown in table 2, can be with Each performance parameter is quantified, such as sets multiple grades for each performance, the size of rank is directly proportional to performance number, that is, grade Not higher, performance is better.It is exemplary, it is assumed that safety, connectivity and stability are provided with 5 grades, and respectively 1-5 grades, 5 Grade represents highest level, and comprehensive performance is obtained using average algorithm, then the property of each access point recorded in link information table Energy rank is as shown in table 2.For example, the safety grades of access point " CMCC " are 1 grade in table 2, connectivity grade is 3 grades, is stablized Property grade be 2 grades, overall performance rating is 2 grades, in practical application, the rank of each performance parameter be also provided with it is a variety of, Such as it is advanced, intermediate, rudimentary etc., the embodiment of the present disclosure only schematically illustrates.

Table 2

Step 4032a, network server arranges each access point according to the corresponding switching performance information of each access point Sequence.

Network server can be successively by the mark of the access point recorded in access information and the progress of access-in point information table Match, obtains the corresponding switching performance information of mark of each access point, it should be noted that if not recording in access-in point information table The switching performance information of a certain access point, illustrating the access point not is regular access point, such as the access point is for network The priority of the access point can be set as minimum by the access point etc. of attack.

Since switching performance information includes: at least one of safety, connectivity and stability or may include comprehensive Performance is closed, therefore, according to the different performance for each access point that inquiry obtains, available different ranking results, the disclosure Embodiment assume the mark of access point carried in access information that network server obtains be respectively " CMCC ", " 123 ", " CMCC-WEB " and " ABC " sorts to obtain each by inquiring access-in point information table as shown in Table 2 with the rank of safety The priority ranking of access point is as shown in table 3.The priority ranking of access point be followed successively by from high to low " 123 ", " ABC ", " CMCC " and " CMCC-WEB " takes other performances, and the process as comprehensive performance is ranked up can be with reference to the above process, the disclosure Embodiment repeats no more this.

Table 3

The mark of access point	Safety	Priority
			123	5	5
ABC	4	4
			CMCC	1	1
CMCC-WEB	0	0

It, can since the access point number recorded in the access-in point information table of network server is more due in practical application Can have it is thousands of, successively carry out access point match may operand it is larger, increase the computational load of network server, can basis Terminal present position carries out screening early period.Exemplary, access-in point information table can recorde the location information of multiple access points, Such as global positioning system (English: Global Positioning System；Referred to as: GPS) address, and the access that terminal reports The location information of the current time terminal is carried in information, network server is determined according to the location information of multiple access point Then access point in the regional scope of position indicated by location information in the terminal connects what is carried in access information Access point switching performance information corresponding with the access point filtered out, can effectively reduce matching process in this way.Wherein, the region model Enclosing can be terminal that terminal reports and can be also possible to pre-set range in scanning range.

Step 4033a, network server generates access priority list according to ranking results.

The sequence of each access point and the ranking results of above-mentioned steps 4032a can phases in the access priority list of generation Together.

In second of achievable mode, access information further includes the encryption information of each access point, and encryption information includes: It supports Types of Local Area Networks, support at least one of cryptographic protocol type and encryption instruction, wherein support what Types of Local Area Networks referred to It is the WLAN that access point can be supported, for example, Wi-Fi, WAPI etc..Cryptographic protocol type is supported to refer to access point The encryption standard that can be supported, such as Wi-Fi secure accessing (English: Wi-Fi Protected Access；Referred to as: WPA) assist View, WPA2 (the WPA second edition) agreement, Wired Equivalent Privacy (English: Wired Equivalent Privacy；Referred to as: WEP), Wired Equivalent Privacy-wildcard mode (English: Wired Equivalent Privacy-Pre-Shared Key；Letter Claim: WPA-PSK) agreement etc., it should be noted that PSK, also referred to as personality frame.Encryption instruction, which is used to indicate access point, is No encryption.The process that terminal obtains encryption information can refer to above-mentioned steps 4021, and terminal can be according to the encryption information of acquisition It generates access information and is sent to network server.

Correspondingly, shown in Fig. 4-5, Fig. 4-5 be it is shown according to an exemplary embodiment it is a kind of according to access information to each A access point sorts to obtain the method flow diagram of access priority list, comprising:
