TECHNICAL FIELD
The present invention relates to the field of communications technologies, and in particular, to a wireless local area network authentication method and a mobile terminal.
BACKGROUND
With the development of a mobile data service, a wireless local area network (WLAN) technology becomes a widely used wireless access technology, and various major telecommunications carriers list a wireless local area network as a key service to expand. To attract existing users and facilitate charging, carriers all introduce a web authentication manner. That is, after a user accesses a wireless local area network hotspot of a carrier, the user will be directed to a web authentication page; and after the user enters an account and a password on the web authentication page and authentication is performed by a network server successfully, the user can use a wireless local area network provided by the carrier.
However, although web authentication is beneficial to charging performed by a carrier for usage of a wireless local area network, a user needs to enter an account and a password on a web authentication page each time when the user accesses the wireless local area network. For the user, such a complex and repetitive operation is meaningless, and wastes a lot of time.

DETAILED DESCRIPTION
In order to make the objectives, technical solutions and advantages of the present invention clearer, specific embodiments of the present invention are described in detail in the following with reference to the accompanying drawings. The described embodiments are a part rather than all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
First, it should be noted that, a mobile terminal described in the embodiments of the present invention includes, but is not limited to, a terminal device that can access a wireless local area network, such as a mobile phone or a tablet computer.
Method Embodiments
Embodiment 1
Referring to FIG. 1, Embodiment 1 of the present invention provides a wireless local area network authentication method, which includes the following steps:
Step 11: A mobile terminal automatically obtains an access account and an access password.
The access account and the access password are an account and a password used by the mobile terminal to complete authentication performed by a network server to access a wireless local area network. Specifically, the mobile terminal may store a wireless local area network hotspot of a carrier in advance according to setting of a user, for example, store a service set identifier (SSID) of the wireless local area network hotspot as “ChinaNet”. The mobile terminal needs no account and password to establish a connection to a wireless local area network hotspot; therefore, when the mobile terminal needs to access a wireless local area network, the mobile terminal first automatically establishes a connection to a preset wireless local area network hotspot “ChinaNet”, then sends a wireless local area network access request to the network server, and receives web authentication page data returned by the network server, but does not display a web authentication page to the user. Then, the mobile terminal automatically obtains an access account and an access password of the wireless local area network; and when the mobile terminal automatically obtains the access account and the access password of the wireless local area network, the user does not need to perform any operation.
Step 12: The mobile terminal automatically sends a web authentication request to the network server, where the web authentication request carries the access account and the access password.
The mobile terminal automatically sends a web authentication request to the network server, where the web authentication request carries the access account and the access password that are automatically obtained in step 11, and the web authentication request may be data that is based on a data protocol such as the Hypertext Transfer Protocol (HTTP). The network server authenticates the access account and the access password. If the access account and the access password are correct, the network server returns an authentication result that a network connection succeeds to the mobile terminal; and if the access account and the access password are incorrect, the network server returns an authentication result that a network connection fails to the mobile terminal. In this step, the user does not need to enter the account and the password, and the mobile terminal does not need to display a web authentication interface to the user either, where the web authentication interface is sent by the network server.
In this embodiment, a mobile terminal automatically obtains an access account and an access password, and automatically sends, to a network server, a web authentication request that carries the access account and the access password. By applying this embodiment, a mobile terminal can automatically complete web authentication of a wireless local area network, a user does not need to enter an account and a password, and a web authentication interface does not need to be displayed to the user either, thereby avoiding a complex and repetitive authentication operation and improving user experience.
Embodiment 2
Referring to FIG. 2, Embodiment 2 of the present invention provides another wireless local area network authentication method, which adopts a static authentication manner, and includes the following steps:
Step 21: A mobile terminal stores an access account and an access password.
Optionally, the mobile terminal may select a static authentication manner or a dynamic authentication manner to perform wireless local area network access authentication. In Embodiment 2, the static authentication manner is selected.
The mobile terminal first stores the access account and the access password according to an input of a user, and may also store an SSID of a wireless local area network hotspot, for example, according to the input of the user, store the SSID of the wireless local area network hotspot as “ChinaNet”, store the access account as “user”, and store the access password as “1234”. Herein, the access account and the access password are determined through negotiation between a user and a carrier. The mobile terminal may store multiple SSIDs and access accounts and access passwords corresponding to the multiple SSIDs. For example, the mobile terminal may store SSIDs of both China Telecom and China Mobile. The SSIDs of both China Telecom and China Mobile correspond to different access accounts and access passwords, so that when being connected to a different wireless local area network hotspot, the mobile terminal may perform authentication by using an access account and an access password corresponding to an SSID of the wireless local area network hotspot.
Step 22: The mobile terminal establishes a connection to a wireless local area network hotspot.
Currently, a mobile terminal and a wireless local area network hotspot are connected in an open manner, and therefore the mobile terminal may establish a connection to the wireless local area network hotspot according to the SSID that is stored in advance in step 21.
Step 23: The mobile terminal sends a wireless local area network access request to a network server.
The network server is a network server that provides a service for the wireless local area network hotspot to which the mobile terminal establishes the connection.
Step 24: The network server returns web authentication page data to the mobile terminal.
It should be noted that, after receiving the web authentication page data from the network server, the mobile terminal does not need to display a web authentication page to the user.
Step 25: The mobile terminal automatically obtains the access account and the access password.
The mobile terminal automatically obtains the access account and the access password that are stored in step 21, where the access account and the access password correspond to the SSID of the wireless local area network hotspot that is currently connected to the mobile terminal.
Step 26: The mobile terminal automatically sends a web authentication request to the network server, where the web authentication request carries the access account and the access password.
The mobile terminal encapsulates the access account and the access password that are automatically obtained by the mobile terminal into a web authentication request in a format of an HTTP data packet, and sends the web authentication request to the network server. Therefore, in an authentication process for the mobile terminal to access a wireless local area network, the user does not need to perform an operation such as entering an account and a password, and the mobile terminal does not need to display a web authentication interface to the user either, where the web authentication interface is sent by the network server.
Step 27: The network server authenticates the web authentication request, and returns an authentication result to the mobile terminal.
The network server authenticates the access account and the access password. If the access account and the access password are correct, the network server returns an authentication result that a network connection succeeds to the mobile terminal; and if the access account and the access password are incorrect, the network server returns an authentication result that a network connection fails to the mobile terminal.
In this embodiment, a mobile terminal adopts a static authentication manner to perform wireless local area network authentication. The mobile terminal stores an access account and an access password, establishes a connection to a wireless local area network hotspot, and receives web authentication page data returned by a network server, but does not display the web authentication page data to a user; and then the mobile terminal automatically obtains the access account and the access password, and automatically sends, to the network server, a web authentication request that carries the access account and the access password. The network server authenticates the web authentication request, and returns an authentication result to the mobile terminal. By applying this embodiment, a mobile terminal can automatically complete static web authentication of a wireless local area network, a user does not need to enter an account and a password, and a web authentication interface does not need to be displayed to the user either, thereby avoiding a complex and repetitive authentication operation and improving user experience.
Embodiment 3
Referring to FIG. 3, Embodiment 3 of the present invention provides another wireless local area network authentication method, which adopts a dynamic authentication manner, and includes the following steps:
Step 31: A mobile terminal stores a local phone number.
Optionally, the mobile terminal may select a static authentication manner or a dynamic authentication manner to perform wireless local area network access authentication. In embodiment 3, the dynamic authentication manner is selected.
Optionally, the mobile terminal may store a local phone number and an SSID according to an input of a user, for example, store the SSID as “ChinaNet” and the local phone number as “18912345678” according to the input of the user; and the mobile terminal may also read and store the local phone number by itself. If the mobile terminal is a terminal into which two subscriber identity module cards can be inserted and which can read two local phone numbers, the user selects a local phone number for storing.
Step 32: The mobile terminal establishes a connection to a wireless local area network hotspot.
Step 33: The mobile terminal sends a wireless local area network access request to a network server.
Step 34: The network server returns web authentication page data to the mobile terminal.
Step 32 to step 34 are similar to step 22 to step 24 in Embodiment 2. Refer to Embodiment 2 for specific description, which is not repeated herein.
Step 35: The mobile terminal automatically obtains the local phone number “18912345678” stored in the mobile terminal, and sends, to the network server, a dynamic password request that carries the local phone number “18912345678”.
The dynamic password request carries the local phone number “18912345678”, so that the network server sends, according to the local phone number “18912345678”, a short message that carries a dynamic password, to the mobile terminal whose number is “18912345678”.
Step 36: The network server returns, to the mobile terminal, a short message that carries a dynamic password.
Optionally, the short message that carries the dynamic password may carry a dynamic password and a dynamic account; or may carry only a dynamic password but does not carry a dynamic account.
Step 37: The mobile terminal automatically obtains an access account and an access password.
Optionally, if the short message received in step 36 also carries a dynamic account, the mobile terminal may obtain the dynamic account carried in the short message, to use the dynamic account as the access account, and obtain the dynamic password carried in the short message, to use the dynamic password as the access password; and if the short message received in step 36 does not carry a dynamic account, the mobile terminal may obtain the local phone number stored in the mobile terminal, to use the local phone number as the access account, and obtain the dynamic password carried in the short message, to use the dynamic password as the access password.
Specifically, the mobile terminal may screen, in a manner of matching a sending number or textual content, the short message that carries the dynamic password; and may obtain the dynamic account or the dynamic password from the short message in a manner of matching a keyword. For example, the mobile terminal screens, in a manner of matching a sending number “10001”, the short message that carries the dynamic password; and if a calling number of a certain received short message is “10001”, the mobile terminal considers that the short message is the short message that carries the dynamic password. Alternatively, the mobile terminal screens, in a manner of matching content that includes a text similar to “WLAN”, “WiFi”, “password”, and the like, the short message that carries the dynamic password, and the mobile terminal scans a received short message; and if a certain short message carries textual content such as “WLAN” or “password”, the mobile terminal considers that the short message is the short message that carries the dynamic password. Then, the mobile terminal obtains the dynamic account and the dynamic password by matching a keyword, such as “account”, “user name”, or “password”. The following short message is used as an example: “Dear user, your temporary WLAN access account is 31919236104, and the password is 807602, valid within 6 hours.” In this case, the mobile terminal scans the short message, matches keywords “account” and “password”, and reads a dynamic account as “31919236104” and a dynamic password as “807602”. If the short message is “Dear user, your temporary WLAN access password is 807602, valid within 6 hours”, and the mobile terminal, through scanning and matching, reads the dynamic password as “807602” but fails to read the dynamic account, the mobile terminal obtains the local phone number “18912345678” that is stored in step 31, to use the local phone number “18912345678” as the access account. In this way, the mobile terminal can automatically obtain an access account and an access password, so that the user neither needs to read a short message from the network server, nor needs to perform an operation of entering a dynamic password or a dynamic account included in the short message.
Step 38: The mobile terminal automatically sends a web authentication request to the network server, where the web authentication request carries the access account and the access password.
Step 39: The network server authenticates the web authentication request, and returns an authentication result to the mobile terminal.
Step 38 and step 39 are similar to step 26 to step 27 in Embodiment 2. Refer to Embodiment 2 for specific description, which is not repeated herein.
In this embodiment, a mobile terminal adopts a dynamic authentication manner to perform wireless local area network authentication. The mobile terminal stores a local phone number, and establishes a connection to a wireless local area network hotspot; the network server returns web authentication page data to the mobile terminal; the mobile terminal sends, to the network server, a dynamic password request that carries the local phone number; the network server returns, to the mobile terminal, a short message that carries a dynamic password; and then the mobile terminal automatically obtains an access account and an access password, and automatically sends, to the network server, a web authentication request that carries the access account and the access password; and the network server authenticates the web authentication request, and returns an authentication result to the mobile terminal. By applying this embodiment, a mobile terminal can automatically complete dynamic web authentication of a wireless local area network, a user does not need to enter a local phone number, an access password, or an access account when the user accesses the wireless local area network, and a web authentication interface does not need to be displayed to the user either, and the user does not need to read a short message that carries a dynamic password, thereby avoiding a complex and repetitive authentication operation and improving user experience.

Specifically, first the memory 44b stores a local phone number and an SSID according to an input of a user by using the input/output apparatus 43. The following is an example. The SSID is stored as “ChinaNet” and the local phone number is stored as “18912345678” according to the input of the user. When the mobile terminal needs to access a wireless local area network, the second reader 413 obtains the local phone number “18912345678” stored in the memory 44b, and then the dynamic password requester 414 obtains the local phone number “18912345678” from the second reader 413, and sends, by using the input/output apparatus 43, a dynamic password request that carries the local phone number “18912345678” to the network server; and the network server sends a short message that carries the dynamic password to the mobile terminal whose number is “18912345678”, where the short message that carries the dynamic password may carry a dynamic password and a dynamic account, or may carry only a dynamic password but does not carry a dynamic account.
Specifically, the short message determiner 415 may perform screening in a manner of matching a sending number or textual content, so as to receive the short message that carries the dynamic password. For example, the short message determiner 415 screens, in a manner of matching a sending number “10001”, the short message that carries the dynamic password; and if a calling number of a certain received short message is “10001”, the short message determiner 415 considers that the short message is the short message that carries the dynamic password. Alternatively, the short message determiner 415 screens, in a manner of matching content that includes a text similar to “WLAN”, “password”, and the like, the short message that carries the dynamic password, and the short message determiner 415 scans a short message that is received by using an input/output device; and if a certain short message carries textual content such as “WLAN”, “WiFi”, “password”, and the like, the short message determiner 415 considers that the short message is the short message that carries the dynamic password. After obtaining the short message that carries the dynamic password from the short message determiner 415, the second reader 413 may obtain the dynamic account or the dynamic password from the short message in a manner of matching a keyword, for example by matching “account”, “user name”, or “password”. The following short message is used as an example: “Dear user, your temporary WLAN access account is 31919236104, and the password is 807602, valid within 6 hours.” In this case, the second reader 413 scans the short message, matches keywords “account” and “password”, and reads a dynamic account as “31919236104” and a dynamic password as “807602”. If the short message is “Dear user, your temporary WLAN access password is 807602, valid within 6 hours”, and the second reader 413, by scanning and matching, reads the dynamic password as “807602” but fails to read the dynamic account, the second reader 413 obtains the local phone number “18912345678” that is stored in step 31, to use the local phone number “18912345678” as the access account. In this way, the mobile terminal can automatically obtain an access account and an access password, so that the user neither needs to read a short message from the network server, nor needs to perform an operation of entering a dynamic password or a dynamic account included in the short message.
Then, the second transmitter 416 obtains the access account and the access password from the second reader 413, and transmits them to the web authentication request initiating apparatus 42; the web authentication request initiating apparatus 42 encapsulates the access account and access password into a web authentication request that is based on a data protocol such as the HTTP, and automatically sends, by using the input/output apparatus 43, the web authentication request to the network server for authentication.
In this embodiment, the mobile terminal accesses a wireless local area network in a dynamic authentication manner, and includes the following structure: the account and password obtaining apparatus 41, the web authentication request initiating apparatus 42, the input/output apparatus 43, and the memory 44b, where the account and password obtaining apparatus 41 further includes: the second reader 413, the dynamic password requester 414, the short message determiner 415, and the second transmitter 416, where the memory 44b stores a local phone number, the second reader 413 reads the local phone number stored in the memory 44b, and the dynamic password requester 414 obtains the local phone number from the second reader 413, and sends, to a network server by using the input/output apparatus 43, a dynamic password request that carries the local phone number; and then the short message determiner 415 receives, by using the input/output apparatus 43, a short message that carries a dynamic password from the network server, the second reader 413 obtains an access account and an access password from the short message that carries the dynamic password, the second transmitter 416 obtains the access account and the access password from the short message that carries the dynamic password, and sends the access account and the access password to the web authentication request initiating apparatus 42, the web authentication request initiating apparatus 42 generates, according to the access account and the access password, a web authentication request that carries the access account and the access password, and sends the web authentication request to the network server by using the input/output apparatus 43, and the network server performs authentication. By applying this embodiment, a mobile terminal only needs to store a local phone number to automatically complete web authentication of a wireless local area network, so that a user does not need to read a short message from a network server, the account and the password do not need to be repeatedly entered, and a web authentication interface does not need to be displayed to the user, thereby avoiding a complex and repetitive authentication operation and improving user experience.
