## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation of U.S. patent application Ser. No. 14/980,412, filed on Dec. 28, 2015, which is a continuation of International Application No. PCT/CN2014/075529, filed on Apr. 16, 2014. Both of the aforementioned applications are hereby incorporated by reference in their entireties.


TECHNICAL FIELD
The present disclosure relates to the field of communications, and in particular, to a wireless local area network access method, a terminal, and a server.
BACKGROUND
As wireless access points are widely deployed, Internet access via a wireless local area network (WLAN) becomes an important manner of Internet access. A user manually selects, on a terminal, a wireless access point that needs to be accessed and manually enters a password to access the access point. Thereby the user may access the internet via the WLAN.
At present, when a terminal moves from one location to another location, because a surrounding wireless access point probably changes, in this case, a user generally needs to reset information related to the wireless access point for connection. That is, the user cannot connect to the WLAN before reselecting an appropriate wireless access point and re-entering a password. The resetting manner brings an operation burden to the user.
In other approaches, in order to solve the foregoing problem, the following two manners may be used for implementation.
Manner 1: Implementation in a Wi-Fi Protected Setup (WPS) manner. This manner can help a user automatically set a network name (that is, a service set identifier (SSID)) and a security secret key. When a terminal moves to a new location, because a function key is generally designed on a body of a wireless product having such a function, the user presses the function key or enters a personal identification number (PIN) code, and then performs two or three operations to implement wireless password setting and wireless connection between a client and a router.
Manner 2: Collecting a large amount of wireless access point information in advance in an application of a terminal, where the information includes a name of a wireless access point and a corresponding connection password when a connection password is set for the wireless access point. If the terminal moves to a new location, when the terminal runs the application, wireless access points surrounding the terminal at that time are displayed to a user. Then, the user manually selects, according to a requirement, a specific wireless access point for connection.
It can be seen from the foregoing that, in the foregoing two manners, manual operation steps of a user are simplified to some extent. However, in the two manners, the user needs to be involved, and the user at least needs to manually select a specific wireless access point.

DESCRIPTION OF EMBODIMENTS
The following clearly describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. The described embodiments are merely a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
Embodiment 1
Embodiment 1 of the present disclosure provides a WLAN access method, which is applied to a terminal. The terminal may be a mobile phone, a notebook computer, a tablet computer, a personal digital assistant, or any mobile device that has a function of accessing a WLAN. As shown in FIG. 1, the method includes the following steps.
101: A terminal sends a request for querying an available wireless access point to a server, to query information about the available wireless access point.
Because a wireless local area network features regionality, when the terminal is located in different geographic locations, a wireless access point in an environment surrounding the terminal also changes. Therefore, in this step, when a user starts WLAN access on the terminal, the terminal sends the request for querying an available wireless access point to the server, to query the information about the available wireless access point. Wireless access point information includes at least one wireless access point identifier. The wireless access point identifier is generally represented by an SSID, and is used to differentiate wireless access points.
Wireless access points near the environment in which the terminal is located are not necessarily managed by a server associated with the terminal. Therefore, step 101 may be that the terminal sends the request for querying an available wireless access point to the server, to query a wireless access point managed by the server.
For example, after the user starts WLAN access, and when the terminal detects that a geographical location in which the terminal is located changes, the terminal sends the query request to the server, to query the wireless access point managed by the server. For another example, as long as the terminal detects that the geographical location in which the terminal is located changes, the terminal sends, to the server, the request for querying the available wireless access point managed by the server. A condition for triggering the terminal to send the query request is not specifically limited in the present disclosure.
Optionally, in this step, the request for querying the available wireless access point may carry at least one of the following parameters: an area identifier, a charge rate identifier, a traffic identifier, and a duration identifier. When the query request sent by the terminal to the server carries the foregoing parameters, the server finds a matched wireless access point according to a parameter condition. The area identifier is used to identify an area range to which the wireless connection point belongs as required in the query request sent by the terminal to the server. For example, it is required that the wireless connection point is located within a range of 30 meters from a terminal location. The terminal location may be represented in a form, such as latitude and longitude, a geographic name, and a building name. The charge rate identifier is used to identify a charge rate type to which the wireless connection point belongs as required in the query request sent by the terminal to the server. The traffic identifier is used to identify a traffic type to which the wireless connection point belongs as required in the query request sent by the terminal to the server. The duration identifier is used to identify a minimum usage time of the wireless connection point as required in the query request sent by the terminal to the server.
It can be understood that a parameter carried in the query request sent by the terminal to the server includes but is not limited to the foregoing parameters.
The request for querying the available wireless access point may carry no parameter. For example, when the query request sent by the terminal to the server does not carry any parameter, the server provides the terminal with all wireless access points managed by the server.
102: The terminal receives wireless access point information returned by the server.
In this step, when the server receives the request for querying the available wireless access point from the terminal, the server returns, according to the request, corresponding wireless access point information. It can be understood that, when the wireless access point information includes multiple wireless access points, the wireless access points may form a wireless access point list and are returned by the server to the terminal in a list form. That is, the wireless access point information returned by the server and received by the terminal is the wireless access point list.
Optionally, when step 101 is that the terminal sends the request for querying an available wireless access point to the server, to query the wireless access point managed by the server, correspondingly, step 102 is that, after the server obtains, by querying, and sends information about wireless access points managed by the server, the terminal receives the wireless access point information returned by the server.
It can be understood that, after step 102, a step of storing, by the terminal, the received wireless access point information may further be included.
103: The terminal determines a specific wireless access point from the received wireless access point information.
The specific wireless access point represents a wireless access point, and preferably, the access point may be a most appropriate wireless access point. In some cases, the access point may also be a second appropriate wireless access point, which is not specifically limited in the present disclosure.
Optionally, in an embodiment of the present disclosure, step 103 may include determining the specific wireless access point from the received wireless access point information according to a preset rule, where the preset rule is one or more of the following: a signal strength, a charge rate, available traffic, and the like. The user may choose to set the preset rule according to a requirement of the user. For example, when the user learns that a WLAN in an area in which the terminal is located is charged, the rule may be set to a “charge rate”, and the terminal determines a wireless access point with a lowest charge rate from the received wireless access point information. For another example, in order to obtain a good and long-term valid Internet access environment, the user may set the rule to signal strength and available traffic, and the terminal determines a wireless access point with a strongest signal strength and most available traffic from the received wireless access point information.
It should be noted that the foregoing preset rule may be the same as a type of a parameter carried in the foregoing request, sent by the terminal to the server, for querying the available wireless access point. For example, in a case in which a default setting is used in a system and not manually modified, when the type of the parameter carried in the request, sent by the terminal to the server, for querying the available wireless access point is the traffic identifier, the preset rule is the available traffic by default. In addition, the two may also be different, and this may be set according to a condition by the user, which is not limited in the present disclosure.
In addition, in a common case, a WLAN service provider (namely, an operator that provides a WLAN service) charges for a WLAN provided to the user, and from a perspective of the WLAN service provider, proper allocation of network resources helps reduce costs. Different network resources are generally allocated to different users by means of allocating different network permissions. Permission allocation may use such a policy: more networks are used, a higher permission is allocated. For example, duration and traffic that a terminal A uses a network are greater than duration and traffic that a terminal B uses a network, and then a permission allocated to the terminal A is higher than a permission allocated to the terminal B, that is, the terminal A obtains longer duration and more traffic than the terminal B. This policy can not only meet requirements of different users but also properly allocate the network resources, thereby effectively reducing costs of the WLAN service provider.
Considering the foregoing case in which the server allocates a permission to the terminal before the terminal is connected to a network, optionally, in an embodiment of the present disclosure, before step 103, the method further includes the following steps.
First, the terminal sends a connection permission application request to the server, where the connection permission application request is used to request the server to determine whether the terminal has a connection permission. Then, in a case of having the connection permission, the terminal receives a permission allocation result sent by the server.
In this case, step 103 includes that the terminal determines the specific wireless access point from the wireless access point information according to the received permission allocation result.
More specifically, after the terminal sends the connection permission application request to the server, if the server determines that the terminal has the connection permission, the server allocates a permission to the terminal; after the server sends the permission allocation result to the terminal, the terminal receives the permission allocation result sent by the server; and then the terminal determines the specific wireless access point from the wireless access point information according to the permission allocation result. For example, the server allocates 100 megabit traffic to a wireless access point A and allocates 50 megabit traffic to a wireless access point B, and the server returns the foregoing information to the terminal. Then, the terminal may preferably select, according to the foregoing information, the wireless access point A with more traffic for connection.
The connection permission application request may carry parameters in the following four forms, to apply to the server for the connection permission.

    
    
        Form 1: The connection permission application request carries a terminal identifier.
        Form 2: The connection permission application request carries a user identifier.
        Form 3: The connection permission application request carries a terminal identifier, a permission application type, and a permission value corresponding to the permission application type, where the permission type includes traffic, connection duration, a charge, and the like.
        Form 4: The connection permission application request carries a user identifier, a permission application type, and a permission value corresponding to the permission application type, where the permission type includes traffic, connection duration, a charge, and the like.
    
    


In the foregoing form 1, a terminal is used as a unit in this manner, that is, when the terminal requests the connection permission from the server, and the terminal reports the terminal identifier to the server. In this way, the server may allocate the permission according to the terminal identifier. In addition, only the terminal identifier is carried, and therefore, the server allocates the permission according to a policy of the server. An allocation policy may be the aforementioned policy “more networks are used, a higher permission is allocated”. For example, in a case in which the permission type is the traffic, if the terminal uses more traffic of a cellular network provided by the operator, the operator rewards the terminal with more WLAN traffic.
In the foregoing form 2, a user is used as a unit in this manner, and this manner is applicable to a scenario in which a same user uses multiple terminals. The user needs to register with the server to establish a binding relationship between the user identifier and a terminal identifier. When a terminal applies for a connection permission, the user identifier needs to be carried. In addition, only the user identifier is carried, and therefore, the server allocates the permission according to a policy of the server. An allocation policy may be the aforementioned policy “more networks are used, a higher permission is allocated”.
In the foregoing form 3, a terminal is used as a unit in this manner, that is, when the terminal requests the connection permission from the server, the terminal reports the terminal identifier to the server. In this way, the server may allocate the permission according to the terminal identifier. In addition, besides the terminal identifier that is carried, the permission application type and the permission value corresponding to the permission application type are further carried. In this case, the server determines whether the permission type and the permission value corresponding to the permission type that are of the permission applied for by the terminal are within an allocation range. If the permission type and the corresponding permission value that are of the permission applied for by the terminal are within the allocation range, the server allocates a corresponding permission to the terminal; and if the permission type and the corresponding permission value that are of the permission applied for by the terminal are not within the allocation range, the server provides, according to an allocation policy of the server, an allocable permission to the terminal.
In the foregoing form 4, a user is used as a unit in this manner, and this manner is applicable to a scenario in which a same user uses multiple terminals. The user needs to register with the server to establish a binding relationship between the user identifier and a terminal identifier. In this way, when a terminal applies for a connection permission, only the user identifier needs to be carried. In addition, besides the user identifier that is carried, the permission application type and the permission value corresponding to the permission application type are further carried. In this case, the server determines whether the permission type and the permission value corresponding to the permission type that are of the permission applied for by the terminal are within an allocation range. If the permission type and the corresponding permission value that are of the permission applied for by the terminal are within the allocation range, the server allocates a corresponding permission to the terminal; and if the permission type and the corresponding permission value that are of the permission applied for by the terminal are not within the allocation range, the server provides, according to an allocation policy of the server, an allocable permission to the terminal.
The following uses an example to describe how the terminal sends a permission application request carrying a parameter and how the server allocates a WLAN access service permission to the terminal according to a permission request. For example, parameters carried in a connection permission request are a terminal identifier and connection duration. First, the terminal collects statistics about duration that the terminal uses a cellular network for data communication within a specific period of time. For example, duration that the terminal uses the cellular network in five days before a current day of statistics collection is one hour. Then, the terminal sends a permission request to the server according to a duration result obtained through statistics collection, where the request carries a cellular network usage status within the specific period of time, for example, a start date is a first day, an end date is a fifth day, and the duration is 1 hour. The server determines, according to the foregoing received information, whether the permission request is within an allocation range. If it is determined that the permission request is within the allocation range, the terminal is allocated a WLAN access permission with same duration, and the allocation result is returned to the terminal. If it is determined that the permission request is not within the allocation range, the server sends prompt information being “incomformity” to the terminal, and sends, to the terminal according to an allocation policy of the server, information for confirming whether a permission is allocated in this way. After the terminal sends confirmation, the server allocates the permission to the terminal.
As shown in FIG. 2, this embodiment of the present disclosure further provides a display interface for permission connection. In a main control interface shown in FIG. 2, when a switch is in an “on” state, a signal strength icon may use a color or shape to identify that the terminal is connected to a wireless access point. For example, the signal strength icon turns green and a quantity of bars is displayed dynamically to show a signal strength. When the switch is in an “off” state, the signal strength icon may use another color or shape to identify that the connection is ended, for example, the signal strength icon turns grey and is in a static state. In addition, on the interface, there is also a configuration button that is used to set a permission type. After the user clicks the configuration button, another new interface can be displayed to the user, namely, a permission type setting interface shown in FIG. 2. On the interface, there may be three permission types, and the user may select one or more types in the three types according to a requirement. After the user selects a permission type, the terminal collects statistics about data corresponding to the permission type, and sends the data to the server, to apply for a corresponding permission.
104: The terminal acquires authentication information of the specific wireless access point from the server, where the authentication information is used to connect the terminal to the specific wireless access point corresponding to the authentication information.
Optionally, in an embodiment of the present disclosure, step 104 may include the following steps.
1041: The terminal sends, to the server, an authentication information request corresponding to the specific wireless connection point.
In a process in which the terminal requests, from the server, the authentication information corresponding to the specific wireless access point, a wireless access point identifier and the terminal identifier; or a wireless access point identifier and the user identifier may be carried.
1042: The terminal receives the authentication information that is corresponding to the specific wireless access point and sent by the server.
The authentication information may be a password, or may be a combination of “user name-password”.
In this case, the method further includes the following steps.
1043: The terminal sends the received authentication information to the specific wireless access point, to apply for authentication.
For example, the terminal sends a user name being “User1” and password being “Vvvv” to a wireless access point AP1, to apply for authentication.
1044: The terminal receives an authentication result sent by the specific wireless access point, where if the authentication result is that the authentication is successful, the terminal connects to a network using the specific wireless access point.
More specifically, when the terminal receives an authentication result sent by the specific wireless access point AP1, and if the authentication result is that the authentication is successful, the terminal connects to the network using the specific wireless access point AP1.
In addition, before step 103, a step of applying to the server for a connection permission by the terminal is further included. The terminal sends a connection permission application request to the server, where the connection permission application request is used to request the server to determine whether the terminal has the connection permission. In a case of having the connection permission, the terminal receives a permission allocation result sent by the server. Therefore, the terminal determines the specific wireless access point in wireless access point information according to the received permission allocation result. That is, the server allocates a permission to the terminal according to the request, and when the permission is successfully allocated, the terminal may connect to the specific wireless access point. In this case, the terminal needs to report a permission usage status to the server. Therefore, after the terminal is connected to the specific wireless access point, the method further includes the following steps.
First, the terminal sends permission usage information to the server. The permission usage information includes the terminal identifier and consumed permission information, or the user identifier and consumed permission information.
The permission usage permission is corresponding to “a parameter carried in the connection permission application request” described above. That is, when a terminal is used as a unit, the permission usage information includes the terminal identifier and the consumed permission information; when a user is used as a unit, the permission usage information includes the user identifier and the consumed permission information. In addition, the permission usage information may further include the wireless access point identifier, authentication information (for example, a user name), and the like.
Then, the terminal receives unused permission information sent by the server, where the unused permission information is obtained by the server by performing processing according to a permission allocated to the terminal and the permission usage information.
The unused permission information is obtained by the server by performing processing according to the permission allocated to the terminal and the permission usage information. That is, the unused permission information of the terminal includes the terminal identifier and unconsumed permission information; or the user identifier and unconsumed permission information. The unconsumed permission information may be represented by a value, where the value equals to a value obtained by subtracting a value of a used permission from a value of an allocated permission. For example, the value corresponding to the permission allocated to the terminal is 1 hour, the value corresponding to the used permission is 0.8 hour, and the value corresponding to the unused permission information is 0.2 hour.
Then, the terminal acquires the unused permission information sent by the server, and when the unused permission information is that the permission corresponding to the terminal is already exhausted, the terminal is disconnected from the specific wireless access point.
The WLAN access method provided in Embodiment 1 of the present disclosure is applied to a terminal. First, the terminal sends a request for querying an available wireless access point to a server, to query information about the available wireless access point; then, the terminal receives wireless access point information returned by the server, and determines a specific wireless access point from the wireless access point information; then, the terminal acquires authentication information of the specific wireless access point from the server, where the authentication information is used to connect the terminal to the specific wireless access point corresponding to the authentication information. It can be seen from the foregoing that the terminal determines the specific wireless access point from the received wireless access point information returned by the server, and this manner avoids a problem that when the wireless access point changes, a user needs to perform a manual operation to select a wireless access point from multiple wireless access points. Therefore, this manner is more intelligent and can further simplify a user operation.
Embodiment 2
Embodiment 2 of the present disclosure provides a WLAN access method, which is applied to a server. As shown in FIG. 3, the method includes the following steps.
201: A server receives a request that is for querying an available wireless access point and sent by a terminal.
Because a wireless local area network features regionality, when the terminal is located in different geographic locations, a wireless access point in an environment surrounding the terminal also changes. Therefore, in this step, when a user starts WLAN access on the terminal, the server receives the request that is for querying the available wireless access point and sent by the terminal. The query request is used to query information about the available wireless access point.
Wireless access points near the environment in which the terminal is located are not necessarily managed by a server that is associated with the terminal. Therefore, the server receives the query request sent by the terminal, where the query request is used to query a wireless access point managed by the server.
Optionally, the request for querying the available wireless access point may carry at least one of the following parameters: an area identifier, a charge rate identifier, a traffic identifier, and a duration identifier. Represented meanings of the three parameters are the same as those described in Embodiment 1, and are not repeatedly described herein.
It can be understood that the request for querying the available wireless access point may carry no parameter. For example, when the query request sent by the terminal to the server does not carry any parameter, the server may provide the terminal with all wireless access points managed by the server.
202: The server obtains information about the available wireless access point according to the query request, and sends the obtained information about the available wireless access point to the terminal.
More specifically, the server obtains, by querying according to the query request, the information about the available wireless access point from storage of the server, and sends, to the terminal, the information that is of the available wireless access point and obtained by querying. The available wireless access point information includes at least one wireless access point identifier, where the identifier is used to differentiate different wireless access points.
Considering that, in a common case, a WLAN service provider charges for a WLAN provided to the user, on a basis of meeting a user requirement, proper allocation of network resources helps reduce costs. Different network resources are generally allocated to different users by means of allocating different network permissions. Permission allocation may use such a policy: more cellular networks are used, a higher WLAN access permission is allocated. This policy can not only meet requirements of different users but also properly allocate the network resources, thereby effectively reducing costs of the WLAN service provider.
Based on a case in which the server allocates a permission to the terminal before the terminal is connected to a network, optionally, in an embodiment of the present disclosure, after the server sends the obtained wireless access point information to the terminal in step 202, the method further includes determining whether the terminal has a connection permission.
Determining whether the terminal has a connection permission specifically is divided into the following several steps.
First, the server receives a connection permission application request sent by the terminal.
Then, the server determines, according to the received request, whether the terminal can be allocated a connection permission.
Then, when the server determines that the terminal can be allocated the connection permission, the server sends a permission allocation result to the terminal. Optionally, the server may store the permission allocation result that is sent to the terminal.
Optionally, in an embodiment of the present disclosure, a parameter carried in the connection permission application request includes a terminal identifier; or a user identifier; or a terminal identifier, a permission application type, and a permission value corresponding to the permission application type; or a user identifier, a permission application type, and a permission value corresponding to the permission application type. Meanings of the parameters in the four forms are the same as those in Embodiment 1, and are not repeatedly described herein.
203: When the server receives an authentication information request of a specific wireless access point from the terminal, the server sends authentication information corresponding to the specific wireless access point to the terminal, where the authentication information is used to connect the terminal to the specific wireless access point.
More specifically, when the server receives the authentication information request of the specific wireless access point from the terminal, the server selects, according to the authentication information request of the terminal, corresponding authentication information and sends the authentication information to the terminal. The authentication information may be a password, or may be a combination of “user name-password”. Then, the terminal sends the received authentication information to the specific wireless access point, to apply for authentication, and if the authentication is successful, the terminal may connect to a network using the specific wireless access point.
In addition, considering that a case in which the server allocates a permission to the terminal exists before the terminal is connected to the wireless access point, correspondingly, after the terminal is connected to the specific wireless access point, a case in which the terminal consumes the permission also exists. Therefore, optionally, in an embodiment of the present disclosure, after the terminal is connected to the specific wireless access point, the following steps are further included.
2041: The server receives permission usage information sent by the terminal.
The permission usage information includes the terminal identifier and consumed permission information, or the user identifier and consumed permission information. In addition, the permission usage information may further include parameters, such as a wireless access point identifier, and authentication information (for example, a user name).
2042: The server performs processing according to a permission allocated to the terminal and the permission usage information to obtain unused permission information of the terminal.
The unused permission information is obtained by the server by performing processing according to the permission allocated to the terminal and the permission usage information. That is, the unused permission information of the terminal includes the terminal identifier and unconsumed permission information; or the user identifier and unconsumed permission information. The unconsumed permission information may be represented by a value, where the value equals to a value obtained by subtracting a value of a used permission from a value of an allocated permission. For example, the value corresponding to the permission allocated to the terminal is 1 hour, the value corresponding to the used permission is 0.8 hour, and the value corresponding to the unused permission information is 0.2 hour.
2043: The server sends the unused permission information to the terminal, where the unused permission information is used by the terminal to determine whether to keep connected to the specific wireless access point.
For example, when the permission corresponding to the terminal is already exhausted, the terminal is disconnected from the specific wireless access point.
Embodiment 2 of the present disclosure provides a WLAN access method, which is applied to a server. First, the server receives a request that is for querying an available wireless access point and sent by a terminal; then, the server obtains information about the available wireless access point according to the query request, and sends the obtained information about the available wireless access point to the terminal; then, when receiving an authentication information request of a specific wireless access point from the terminal, the server sends authentication information corresponding to the specific wireless access point to the terminal, where the authentication information is used to connect the terminal to the specific wireless access point. It can be seen from the foregoing that the terminal determines the specific wireless access point from the received wireless access point information returned by the server, and this manner avoids a problem that when the wireless access point changes, a user needs to perform a manual operation to select a wireless access point from multiple wireless access points. Therefore, this method is more intelligent and further simplifies a user operation.
In addition, before the terminal applies to the server for corresponding authentication information for connecting to the specific wireless access point, the server needs to have the authentication information of the specific wireless access point in advance. Therefore, optionally, the method further includes the following step.
Acquire wireless connection authentication information from at least one WLAN service provider.
Preferably, the wireless connection authentication information is acquired in batches. In addition, the acquiring manner may also be acquiring one by one, which is not specifically limited in the present disclosure.
Optionally, the foregoing step may be divided into the following several steps. First, send, to the at least one WLAN service provider, a request for applying for connection authentication information. After the WLAN generates and sends the connection authentication information according to the request, receive the authentication information provided by the WLAN service provider; and store the received authentication information.
The authentication information may be a password, or may be a combination of “user name-password”. Using a form of “user name-password” as an example, the authentication information may be a form shown in Table 1. In this way, an available user name and password may be retrieved according to a wireless access point identifier.











TABLE 1
