DESCRIPTION OF EMBODIMENTS

The following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely some but not all of the embodiments of the present invention. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
FIG. 1 is a schematic diagram of an application scenario in which a mobile terminal accesses a wireless local area network established by a hotspot terminal according to an embodiment of the present invention. As shown in FIG. 1, a device A is a hotspot terminal, and the device A is used as an application access point (AP) of a wide area network (WAN) to log in to a remote network. A device B is a mobile terminal on a local area network (LAN) side, and the mobile terminal accesses a wireless local area network (WLAN) established by the device A that is used as an AP, so as to implement data services, such as watching a video, browsing a web page, instant messaging, or listening to music. In the application scenario of this embodiment of the present invention, a person who operates the device A is referred to as an administrator, and a person who operates the device B is referred to as a user.
FIG. 2 is a schematic diagram of an application scenario in which a mobile terminal accesses a wireless local area network established by a hotspot terminal according to another embodiment of the present invention. As shown in FIG. 2, a device A is a hotspot terminal and is used as an application access point of a WAN to log in to a remote network. A device B is a mobile terminal on a LAN side, and the mobile terminal accesses a WLAN established by the device A that is used as an AP, so as to implement data services, such as watching a video, browsing a web page, instant messaging, or listening to music. A device C is a mobile terminal on the LAN side and is referred to as a management terminal. In the application scenario of this embodiment of the present invention, a person who operates the device C is referred to as an administrator, and a person who operates the device B is referred to as a user.
In the present invention, a mobile terminal involved may be, for example, a mobile phone, a personal computer (PC), a tablet computer, a digital camera, and a game console. A hotspot terminal may be, for example, a wireless router, a portable router, a wireless modem, a mobile phone, a PC, a tablet computer, and a digital camera. A management terminal may be, for example, a mobile phone, a PC, a tablet computer, a digital camera, and a game console.
In the prior art, to ensure security of a mobile terminal that accesses a wireless local area network, a hotspot terminal establishes a wireless local area network for which a password is set. A correct password needs to be entered for the mobile terminal to access an encrypted WLAN established by the hotspot terminal, so as to implement a data service. In some application scenarios, when the mobile terminal accesses the encrypted WLAN established by the hotspot terminal, the following problems are likely to occur: it is difficult to enter the password, or it is difficult to acquire the password because the password is too complex; or any mobile terminal can access the encrypted WLAN when the password is disclosed. As a result, a process in which the mobile terminal accesses the encrypted WLAN established by the hotspot terminal is tedious and complex.
FIG. 3 is a schematic flowchart of a network connection method according to an embodiment of the present invention. The method includes the following steps:
S301. A hotspot terminal receives an Internet access request sent by a mobile terminal.
The Internet access request is sent to the hotspot terminal after the mobile terminal accesses, according to a service set identifier (SSID) of the hotspot terminal, an unencrypted WLAN established by the hotspot terminal. When the mobile terminal accesses, according to the SSID of the hotspot terminal, the unencrypted WLAN established by the hotspot terminal, the hotspot terminal acquires a MAC address of the mobile terminal, where the MAC address of the mobile terminal is used to uniquely identify the mobile terminal.
The SSID of the hotspot terminal may be broadcasted by the hotspot terminal in a wireless fidelity (Wi-Fi) manner, or may be broadcasted by the hotspot terminal in another manner, such as near field communication (NFC).
The Internet access request may be specifically a request for logging in to a website, such as sina (a news website), yahoo, sohu (a video website), or youku (a video website); or a request for logging in to another application program that requires Internet access, such as MSN or QQ (a chat tool).
When the mobile terminal finds the SSID of the hotspot terminal, the mobile terminal requests to access, according to the found SSID of the hotspot terminal, the WLAN established by the hotspot terminal. The hotspot terminal establishes the unencrypted WLAN, that is, the mobile terminal may access, according to the SSID, the unencrypted WLAN established by the hotspot terminal in a case in which no password needs to be entered.
FIG. 4 is a schematic diagram of an user interface showing that a mobile terminal finds an SSID of a hotspot terminal; as shown in FIG. 4, the mobile terminal finds an SSID that does not require password entering: E5730-Open, and the mobile terminal may access, according to the E5730-Open, an unencrypted WLAN established by the hotspot terminal.
After the mobile terminal accesses the unencrypted WLAN established by the hotspot terminal, the mobile terminal sends, according to a user requirement such as watching a video, browsing a web page, instant messaging, or listening to music, an Internet access request to the hotspot terminal to request to log in to a remote network by using the hotspot terminal. For example, the mobile terminal requests to log in to sina (a news website), yahoo, sohu (a video website), or youku (a video website) by using the hotspot terminal.
S302. The hotspot terminal sends an input request to the mobile terminal according to the received Internet access request, where the input request is used to request the mobile terminal to send user identity information.
When the hotspot terminal receives the Internet access request sent by the mobile terminal, the hotspot terminal sends the input request to the mobile terminal according to the received Internet access request. Specifically, the mobile terminal requests to log in to a remote network by using the hotspot terminal, and the hotspot terminal prevents, according to the received Internet access request, the mobile terminal from logging in to the remote network, and sends the input request to the mobile terminal to request the mobile terminal to send the user identity information. The user identity information is used to identify a user who uses the mobile terminal, and the user identity information may include at least one piece of information of a user name, a user nickname, a user phone number, and user convention information. The foregoing at least one piece of information of a user name, a user nickname, a user phone number, and user convention information is used to enable an administrator to distinguish an identity of the user.
In another embodiment of the present invention, the hotspot terminal prevents, according to the received Internet access request, the mobile terminal from logging in to the remote network and sends the input request to the mobile terminal, which may be implemented by the hotspot terminal in a redirection manner. That is, the hotspot terminal redirects the Internet access request sent by the mobile terminal to the input request in the redirection manner. For example, the mobile terminal requests to log in to sina, and the hotspot terminal sends an input request to the mobile terminal in the redirection manner; FIG. 5A is an example of a specific display user interface of the input request.
FIG. 5A is a schematic diagram of an user interface showing that a hotspot terminal sends an input request to a mobile terminal. As shown in FIG. 5A, the hotspot terminal sends, according to the received Internet access request, the input request to the mobile terminal to request the mobile terminal to send the user identity information.
The user identity information that requires to be entered is displayed on the schematic diagram of the user interface in FIG. 5A, and for example, may include any one or more of the following information: permission application information, a nickname, and a user phone number.
S303. The hotspot terminal receives the user identity information sent by the mobile terminal.
The user identity information may be, for example, at least one piece of information of a user name, a user nickname, a user phone number, and user convention information. The user convention information may be any information about a convention between the user and the administrator, such as a piece of specific text and a string of specific numbers.
FIG. 5B is a schematic diagram of an user interface of user identity information that is sent by a mobile terminal and received by a hotspot terminal. The schematic diagram of the user interface in FIG. 5B is used as an example for description.
A user enters user identity information according to the user identity information that is displayed on the user interface and requires to be entered; for example, the entered user identity information includes that permission application information is “I am Li Si, and I want to log in to a remote network by using your AP; please approve” and that a nickname is “Tom”. The user identity information sent by the mobile terminal to the hotspot terminal is the permission application information “I am Li Si, and I want to log in to a remote network by using your AP; please approve” and the nickname “Tom”.
It should be noted that a display user interface of the mobile terminal may further include other content, such as “Please notify me of an approval result by an SMS message”, and the user may choose whether to receive the approval result by an SMS message; if the user chooses to receive the approval result by an SMS message, the user may fill in a phone number for receiving the SMS message. In addition, the display user interface of the mobile terminal may further include description about a current WLAN, such as “E5730-Open”, and “This is a wireless router of Zhang San”.
S304. The hotspot terminal receives a permission confirmation instruction that is entered by an administrator according to the user identity information.
Similarly, the schematic diagram of the user interface in FIG. 5B is used as an example for description. After the user enters the user identity information and the user clicks for confirmation (for example, clicks “Apply for Internet access”), the hotspot terminal receives the user identity information sent by the mobile terminal, and the user identity information displayed on the user interface includes the permission application information “I am Li Si, and I want to log in to a remote network by using your AP; please approve” and the nickname “Tom”.
Optionally, the user identity information sent by the mobile terminal may include only the permission application information, or may include only the nickname, or may be other identity information that is used to enable the administrator to identify the user, for example, at least one of a user name, a user phone number, or user convention information.
There may be two manners in which the hotspot terminal receives the permission confirmation instruction that is entered by the administrator according to the user identity information.
One manner is as follows: The hotspot terminal sends the user identity information to a management terminal, and the hotspot terminal receives the permission confirmation instruction sent by the management terminal, where the permission confirmation instruction is entered by the administrator according to the user identity information displayed by the management terminal.
For example, the hotspot terminal sends the user identity information to the management terminal, and the user identity information includes “I am Li Si, and I want to log in to a remote network by using your AP; please approve” and the nickname “Tom”.
The user identity information displayed on an user interface of the management terminal includes the permission application information “I am Li Si, and I want to log in to a remote network by using your AP; please approve” and the nickname “Tom”. According to the user identity information displayed by the management terminal, including the permission application information “I am Li Si, and I want to log in to a remote network by using your AP; please approve” and the nickname “Tom”, the administrator enters the permission confirmation instruction by operating a touchscreen of the management terminal, or pressing a physical button of the management terminal, or in another manner.
In the other manner, receiving, by the hotspot terminal, the permission confirmation instruction that is entered by the administrator according to the user identity information specifically includes: displaying, by the hotspot terminal, the user identity information, and receiving, by the hotspot terminal, the permission confirmation instruction that is entered by the administrator according to the user identity information.
For example, the user identity information is displayed on an user interface of the hotspot terminal, and the user identity information includes the permission application information “I am Li Si, and I want to log in to a remote network by using your AP; please approve” and the nickname “Tom”.
According to the user identity information displayed by the hotspot terminal, including the permission application information “I am Li Si, and I want to log in to a remote network by using your AP; please approve” and the nickname “Tom”, the administrator enters the permission confirmation instruction by operating a touchscreen of the hotspot terminal, or pressing a physical button of the hotspot terminal, or in another manner.
S305. The hotspot terminal determines Internet access permission of the mobile terminal according to the received permission confirmation instruction.
The hotspot terminal determines, according to the received permission confirmation instruction that is entered by the administrator according to the user identity information, whether the mobile terminal can log in to a remote network by using the hotspot terminal.
In this embodiment of the present invention, when a hotspot terminal receives an Internet access request of a mobile terminal, the hotspot terminal sends an input request to the mobile terminal, and the hotspot terminal receives a permission confirmation instruction that is entered by an administrator according to user identity information, and determines Internet access permission of the mobile terminal according to the received permission confirmation instruction. A problem that entering a password when the mobile terminal logs in to a remote network by using the hotspot terminal is complex and tedious is resolved. A convenient and efficient method for performing network connection by the mobile terminal by using the hotspot terminal is provided under the premise of ensuring that the mobile terminal can securely log in to the remote network by using the hotspot terminal.
FIG. 6 is a schematic flowchart of a network connection method according to another embodiment of the present invention. The method includes the following steps:
S601. A mobile terminal accesses, according to an SSID of a hotspot terminal, an unencrypted WLAN established by the hotspot terminal.
The hotspot terminal establishes the unencrypted WLAN, that is, the mobile terminal may access, according to the SSID, the unencrypted WLAN established by the hotspot terminal in a case in which no password needs to be entered. For example, the mobile terminal finds an SSID that does not require password entering: E5730-Open, and the mobile terminal may access, according to the E5730-Open, an unencrypted WLAN established by the hotspot terminal.
The SSID of the hotspot terminal may be broadcasted by the hotspot terminal in a Wi-Fi manner, or may be broadcasted by the hotspot terminal in another manner, such as NFC.
When the mobile terminal accesses, according to the SSID of the hotspot terminal, the unencrypted WLAN established by the hotspot terminal, the hotspot terminal acquires a MAC address of the mobile terminal, where the MAC address of the mobile terminal is used to uniquely identify the mobile terminal.
S602. The mobile terminal sends an Internet access request to the hotspot terminal.
The Internet access request may be specifically a request for logging in to a website, such as sina (a news website), yahoo, sohu (a video website), or youku (a video website); or a request for logging in to another application program that requires Internet access, such as MSN or QQ (a chat tool).
After the mobile terminal accesses the unencrypted WLAN established by the hotspot terminal, the mobile terminal sends, according to a user requirement such as watching a video, browsing a web page, instant messaging, or listening to music, an Internet access request to the hotspot terminal to request to log in to a remote network by using the hotspot terminal. For example, the mobile terminal requests to log in to sina (a news website), yahoo, sohu (a video website), youku (a video website), or the like by using the hotspot terminal.
S603. The hotspot terminal sends an input request to the mobile terminal according to the received Internet access request.
The input request is used to request the mobile terminal to send user identity information.
When the hotspot terminal receives the Internet access request sent by the mobile terminal, the hotspot terminal sends the input request to the mobile terminal according to the received Internet access request. Specifically, the mobile terminal requests to log in to a remote network by using the hotspot terminal, and the hotspot terminal prevents, according to the received Internet access request, the mobile terminal from logging in to the remote network, and sends the input request to the mobile terminal to request the mobile terminal to send the user identity information. The user identity information is used to identify a user who uses the mobile terminal, and the user identity information includes at least one piece of information of a user name, a user nickname, a user phone number, and user convention information.
In another embodiment of the present invention, the hotspot terminal prevents, according to the received Internet access request, the mobile terminal from logging in to the remote network and sends the input request to the mobile terminal, which may be implemented by the hotspot terminal in a redirection manner. That is, the hotspot terminal redirects the Internet access request sent by the mobile terminal to the input request in the redirection manner. For example, the mobile terminal requests to log in to sina, and the hotspot terminal sends an input request to the mobile terminal in the redirection manner; FIG. 5A is an example of a specific display user interface of the input request.
S604. The mobile terminal sends user identity information to the hotspot terminal according to the received input request.
The user identity information may be, for example, at least one piece of information of a user name, a user nickname, a user phone number, and user convention information.
S605. The hotspot terminal displays the received user identity information.
A schematic diagram of an user interface in FIG. 5B is used as an example for description, and permission application information that is entered by the user according to a requirement displayed on the user interface is “I am Li Si, and I want to log in to a remote network by using your AP; please approve.” The user identity information sent by the mobile terminal to the hotspot terminal is the permission application information “I am Li Si, and I want to log in to a remote network by using your AP; please approve” and a nickname “Tom”.
S606. The hotspot terminal receives a permission confirmation instruction that is entered by an administrator according to the user identity information.
The administrator enters the permission confirmation instruction according to the user identity information displayed by the hotspot terminal.
For example, the user identity information is displayed on an user interface of the hotspot terminal, and the user identity information includes the permission application information “I am Li Si, and I want to log in to a remote network by using your AP; please approve” and the nickname “Tom”.
According to the user identity information displayed by the hotspot terminal, where the user identity information includes the permission application information “I am Li Si, and I want to log in to a remote network by using your AP; please approve” and the nickname “Tom”, the administrator enters the permission confirmation instruction by operating a touchscreen of the hotspot terminal, or pressing a physical button of the hotspot terminal, or in another manner.
S607. The hotspot terminal determines Internet access permission of the mobile terminal according to the received permission confirmation instruction.
The hotspot terminal determines, according to the received permission confirmation instruction that is entered by the administrator according to the user identity information, whether the mobile terminal can log in to a remote network by using the hotspot terminal.
In another embodiment of the present invention, after the hotspot terminal performs step S607 and determines that the mobile terminal has the Internet access permission, the hotspot terminal may further perform step S608.
S608. The hotspot terminal sets, according to a preset Internet access condition, an Internet access limitation of accessing the hotspot terminal by the mobile terminal.
The Internet access limitation may be specifically time of accessing the unencrypted WLAN established by the hotspot terminal, or an Internet access range, or a bandwidth limitation.
Optionally, the Internet access limitation may be set by the administrator, or the Internet access limitation may be set according to a result of searching for, by the hotspot terminal according to the MAC address of the mobile terminal, an Internet access condition of the mobile terminal in a pre-stored whitelist.
According to MAC addresses of mobile terminals, the hotspot terminal may set time of accessing, by different mobile terminals, the unencrypted WLAN established by the hotspot terminal, or set Internet access ranges of different mobile terminals, or set bandwidth limitations of different mobile terminals, as shown in Table 1.

TABLE 1

Example:

	Access		Bandwidth
MAC address	time	Internet access range	limitation

44-45-53-54-00-00	10 min	Limited to a news web page	2 Mbit/s
44-45-53-54-00-01	30 min	Limited to a news web page	10 Mbit/s

For a mobile terminal that has Internet access permission, which is determined by the hotspot terminal, the hotspot terminal may establish a whitelist; when the mobile terminal in the whitelist sends an Internet access request again, the hotspot terminal may search the whitelist and determine Internet access permission and an Internet access limitation of the mobile terminal according to the whitelist.
In another embodiment of the present invention, after the hotspot terminal performs step S607 and determines the Internet access permission of the mobile terminal, the hotspot terminal may further perform step S609.
S609. The hotspot terminal sends reminder information to the mobile terminal.
The reminder information is used to remind whether the Internet access request of the mobile terminal is approved.
In this embodiment of the present invention, when a hotspot terminal receives an Internet access request of a mobile terminal, the hotspot terminal sends an input request to the mobile terminal, and the hotspot terminal receives a permission confirmation instruction that is entered by an administrator according to user identity information, and determines Internet access permission of the mobile terminal according to the received permission confirmation instruction.
