Description

TECHNICAL FIELD

The present disclosure relates to the field of communication technologies and, more particularly, to a method and a device for accessing a wireless network.

BACKGROUND

With the development of communication technologies, more and more users use terminals with a wireless access function to access wireless networks. A Wireless Fidelity (Wi-Fi) network is one of the mainstream wireless networks at present.

A conventional method for a terminal to access a Wi-Fi network generally includes the following steps. Firstly, the terminal detects one or more Wi-Fi network access devices, and generates a Wi-Fi network list including one or more Wi-Fi networks provided by the one or more Wi-Fi network access devices. A user of the terminal can then select a Wi-Fi network in the Wi-Fi network list and enter a password. Accordingly, the terminal sends a certification request carrying the password to the Wi-Fi network access device corresponding to the selected Wi-Fi network. The Wi-Fi network access device records the terminal as an authorized device after the password is successfully verified, and returns an authorization response to the terminal. After receiving the authorization response, the terminal sends a request to the Wi-Fi network access device to establish a connection, and the Wi-Fi network access device enables the terminal to access the Wi-Fi network based on the request.

In the conventional method, there are generally multiple input operations, such as selecting the Wi-Fi network and entering the password, required when the user connects the terminal to the Wi-Fi network. However, for a terminal other than a mobile phone or a tablet computer, such as a smart TV, a smart wearable device, a Wi-Fi camera, etc., the terminal may not include an input device for those input operations, which makes it inconvenient for the user to select a Wi-Fi network or enter a password.

DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the invention as recited in the appended claims.

FIG. 1 is a flow chart of a method 100 for accessing a wireless network, according to an exemplary embodiment. For example, the wireless network is a Wi-Fi network, and the method 100 is used in a network access device providing the Wi-Fi network. Referring to FIG. 1, the method 100 includes the following steps.

In step 101, the network access device receives an access request sent from a terminal, and determines whether the terminal meets a free-of-authorization condition based on a terminal identification included in the free-authorization access request. If it is determined that the terminal meets the free-of-authorization condition, the network access device can enable the terminal to access the Wi-Fi network without performing a direct authorization on the terminal device.

In step 102, the network access device sends a connection invitation to the terminal, if it is determined that the terminal meets the free-of-authorization condition.

In step 103, the network access device receives a connection request sent from the terminal based on the connection invitation, and enables the terminal to access the Wi-Fi network based on the connection request.

In the illustrated embodiment, the terminal is enabled to access the Wi-Fi network without receiving a user input operation at the terminal. Accordingly, the access efficiency is improved.

FIG. 2 is a flow chart of a method 200 for accessing a wireless network, according to an exemplary embodiment. For example, the wireless network is a Wi-Fi network provided by a network access device, and the method 200 is used in a terminal, such as a smart TV, a smart wearable device, a Wi-Fi camera, etc. Referring to FIG. 2, the method 200 includes the following steps.

In step 201, the terminal sends, e.g., broadcasts, an access request to the network access device, the access request including a terminal identification of the terminal.

In step 202, the terminal receives a connection invitation sent from the network access device, after the network access device determines that the terminal meets a free-of-authorization condition based on the access request. If it is determined that the terminal meets the free-of-authorization condition, the network access device can enable the terminal to access the Wi-Fi network without performing a direct authorization on the terminal device.

In step 203, the terminal sends a connection request to the network access device based on the connection invitation, for the network access device to enable the terminal to access the Wi-Fi network.

In the illustrated embodiment, the terminal is enabled to access the Wi-Fi network without receiving a user input operation at the terminal. Accordingly, the access efficiency is improved.

FIG. 3 is a flow chart of a method 300 for accessing a wireless network, according to an exemplary embodiment. For example, the wireless network is a Wi-Fi network provided by a network access device. Referring to FIG. 3, the method 300 includes the following steps.

In step 301, a first terminal sends an access request to the network access device, the access request including a terminal identification of the first terminal.

For example, the first terminal is a Wi-Fi terminal to access the Wi-Fi network. In one exemplary embodiment, after the first terminal is turned on, the first terminal periodically broadcasts the access request through its wireless module.

Accordingly, the network access device receives the access request sent from the first terminal, and determines whether the first terminal meets a free-of-authorization condition based on the terminal identification included in the access request. If it is determined that the first terminal meets the free-of-authorization condition, the network access device can enable the terminal to access the Wi-Fi network without performing a direct authorization on the first terminal device.

For example, when receiving the access request, the network access device records into a list of terminals to be confirmed the terminal identification included in the access request and a time, e.g., a first time, when the access request is received. The time when the access request is received can then be used as a parameter to determine whether the first terminal meets the free-of-authorization condition.

In exemplary embodiments, the list of terminals to be confirmed in the network access device is provided to a second terminal possessing a confirmation permission, such that a user can view the list on the second terminal and select a terminal in the list. In one exemplary embodiment, prior to step 301, the second terminal is set to possess the confirmation permission for access to the Wi-Fi network by the first terminal.

Still referring to FIG. 3, in exemplary embodiments, whether the first terminal meets the free-of-authorization condition may be determined as follows. In step 3021, the network access device receives from the second terminal a confirmation request for the access to the Wi-Fi network by the first terminal. In step 3022, the list of terminals to be confirmed, including the terminal identification of the first terminal, is sent to the second terminal. In step 3023, the network access device receives a confirmation sent from the second terminal, the confirmation including a terminal identification selected at the second terminal. In step 3024, it is confirmed that the first terminal meets the free-of-authorization condition, if the terminal identification selected at the second terminal that is included in the confirmation matches the terminal identification of the first terminal included in the access request.

In exemplary embodiments, after confirming that the first terminal meets the free-of-authorization condition, the first terminal may be added into a free-of-authorization terminal list maintained by the network access device. For example, the free-of-authorization terminal list is used for recording terminals that have access to the Wi-Fi network without passing a direct authorization by the network access device, so that the network access device can further confirm a third terminal confirmed by a terminal in the free-of-authorization terminal list when the third terminal accesses the Wi-Fi network. As a result, access security is increased.

In step 303, the network access device sends a connection invitation to the first terminal, if it is determined that the first terminal meets the free-of-authorization condition. For example, the connection invitation includes an identification of the network access device, so that the first terminal can access the Wi-Fi network based on the identification of the network access device.

In step 304, the network access device records the first terminal in the free-of-authorization terminal list, and sets an authorized time period for the first terminal in the free-of-authorization terminal list. When the authorized time period expires, the first terminal will be deleted from the free-of-authorization terminal list, and will not be allowed to access the Wi-Fi network.

In exemplary embodiments, the network access device maintains the free-of-authorization terminal list based on authorized time periods corresponding to the respective terminals satisfying the free-of-authorization condition, and deletes from the free-of-authorization terminal list the record of a terminal for which the authorized time period expires.

In step 305, the first terminal receives the connection invitation sent from the network access device, after the network access device confirms the first terminal meets the free-of-authorization condition based on the access request of the first terminal.

In exemplary embodiments, when the first terminal has a display screen, the identification of the network access device sending the connection invitation is displayed on the display screen, to inform the user that the first terminal will be connected to the network access device. As a result, the user can confirm the connection to the network access device.

In step 306, the first terminal sends a connection request to the network access device based on the connection invitation, so that the network access device enables the first terminal to access the Wi-Fi network. For example, the connection request does not include password information.

Accordingly, the network access device receives the connection request sent from the first terminal, which enables the first terminal to access the Wi-Fi network based on the connection request.

In one exemplary embodiment, when the first terminal accesses the Wi-Fi network, the network access device further performs authorization on the first terminal.

In exemplary embodiments, the network access device performs a search of the terminal identification included in the connection request, in the free-of-authorization terminal list. If the terminal identification is included in the list, accessing the Wi-Fi network is enabled, and if the terminal identification is not included in the list, accessing the Wi-Fi network is refused.

Accordingly, in step 3071, the network access device determines whether the first terminal is included in the free-of-authorization terminal list. In step 3072, the first terminal is enabled to access the Wi-Fi network according to the connection request, if the first terminal is identified in the free-of-authorization terminal list.

In the illustrated embodiment, the first terminal is enabled to access the Wi-Fi network without receiving a user input operation at the first terminal. Accordingly, the access efficiency is improved.
