BACKGROUND
An electronic device such as a personal digital assistance (Personal Digital Assistance, PDA) and a mobile phone can access a network, so as to implement operations such as web browsing, email sending and receiving, and data downloading. The electronic device can access a network in multiple manners. For example, the mobile phone can access a 3G or 4G network by using a subscriber identity module (Subscriber Identity Module, SIM) card; and the PDA can access the Internet network by using a Wireless Fidelity (Wireless Fidelity, Wi-Fi) hotspot. However, in an area beyond the coverage of the Wi-Fi hotspot, the PDA cannot access the network by using the Wi-Fi hotspot.
At present, some electronic devices provide a Bluetooth access point (Access Point, AP) function, that is, a Bluetooth network sharing function. By using the Bluetooth network sharing function, these electronic devices can serve as an AP to provide another electronic device that needs to access the network with a network connection. Based on the foregoing Bluetooth network sharing function, in an area beyond the coverage of a Wi-Fi hotspot, the PDA can access the network by using the electronic device having the Bluetooth network sharing function. For example, the PDA may access the network by using a mobile phone having the Bluetooth network sharing function, and a network access process is that: The mobile phone establishes a Bluetooth connection to the PDA, and then a user turns on the Bluetooth network sharing function of the mobile phone manually, so as to provide the PDA with a network connection.
However, in the foregoing method in which the PDA accesses the network by using a mobile phone having the Bluetooth network sharing function, for each operation, the user needs to turn on the Bluetooth network sharing function (Bluetooth AP function) of the electronic device through manual configuration, which is a troublesome process and leads to an excessively long time to access a network.

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 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.
Referring to FIG. 1, FIG. 1 is a flowchart of a network access method according to an embodiment of the present invention. This embodiment is executed by an electronic device having a Bluetooth AP function, for example, a mobile phone. A Bluetooth terminal described in this embodiment is an electronic device that has a Bluetooth function and needs to access a network, for example, a PDA. As shown in FIG. 1, the network access method provided in this embodiment includes:
101. Establish a Bluetooth connection to a Bluetooth terminal.
102. Receive, by using the Bluetooth connection, a network access request sent by the Bluetooth terminal.
After the connection is established to the Bluetooth terminal, if the Bluetooth terminal needs to access a network, the Bluetooth terminal sends the network access request, for example, a Hyper Text Transportation Protocol (Hyper Text Transportation Protocol, HTTP) request.
Optionally, in a possible implementation manner of this embodiment, before the Bluetooth connection to the Bluetooth terminal is established, the network access method provided in this embodiment may further include:
performing Bluetooth pairing with the Bluetooth terminal, and during a process of the Bluetooth pairing, receiving an authorization request sent by the Bluetooth terminal; and
accepting the authorization request, and identifying the Bluetooth terminal as an authorized device.
For security reasons, Bluetooth pairing needs to be performed before communication is performed between two Bluetooth devices, and then data can be exchanged. Pairing (also referred to as binding sometimes) refers to a process in which two Bluetooth devices exchange protection keys with each other. After pairing succeeds, all information sent between the Bluetooth devices by using the Bluetooth connection is encrypted and can only reach a Bluetooth device that is permitted by the pairing to receive the information. Once pairing between the Bluetooth devices succeeds, the connection can be established.
By using signaling in a process of the Bluetooth pairing, the entity executing this embodiment can receive the authorization request. The authorization request may be a protocol agreed upon between the entity executing this embodiment and the Bluetooth terminal. After receiving the protocol, the entity executing this embodiment accepts the authorization request and identifies the Bluetooth terminal as an authorized device automatically.
Optionally, in another possible implementation manner of this embodiment, after the entity executing this embodiment establishes the Bluetooth connection to the Bluetooth terminal and before the entity executing this embodiment determines whether the Bluetooth terminal is an authorized device, the network access method provided in this embodiment may further include:
prompting a user to input an authorization confirmation instruction of the Bluetooth terminal by using a human-computer interaction manner; and
after the authorization confirmation instruction is received, identifying the Bluetooth terminal as an authorized device.
The entity executing this embodiment stores an authorization record. When an authorized Bluetooth terminal initiates a network request again, the entity executing this embodiment can directly search the authorization record to find whether the Bluetooth terminal that initiates the network request currently is an authorized device.
103. If the Bluetooth terminal is an authorized device, activate a Bluetooth network sharing function automatically and forward the network access request to a wide area network.
The entity executing this embodiment determines whether the Bluetooth terminal that initiates the network access request currently is an authorized device. If the Bluetooth terminal is an authorized device, the entity executing this embodiment activates the Bluetooth network sharing function automatically. Optionally, a method for determining whether the Bluetooth device that initiates the network access request is an authorized device may be: searching an authorization record to find whether authorization for the Bluetooth device is included, where if the authorization for the Bluetooth device is included, the Bluetooth device is an authorized device.
The entity executing this embodiment can provide the Bluetooth terminal with a network access service by means of an access control list (Access Control List, ACL) of Bluetooth. When the Bluetooth terminal is an authorized device, the entity executing this embodiment activates the Bluetooth network sharing function automatically and forwards the network access request to a corresponding server in the wide area network by means of the ACL, so as to obtain requested content.
Optionally, in order to prevent the Bluetooth network sharing function from being activated in a case in which the Bluetooth network sharing function is not required, which leads to a waste of power and resources, and also in order to further improve user experience, in this embodiment, after the network access request is received and the network access request is forwarded to the wide area network, if a new network access request is not received within a preset time, the Bluetooth network sharing function is turned off. The preset time herein may be set to a proper time value according to a specific application, which is not limited herein.
This embodiment further protects a computer storage medium. The computer storage medium stores a computer program, and when the computer program in the computer storage medium is read in a computer, the computer program can enable the computer to implement the foregoing steps in this embodiment.
In this embodiment, when a network access request sent by a Bluetooth terminal is received, and when it is determined that the Bluetooth terminal is an authorized device, a Bluetooth network sharing function is activated automatically and the network access request is forwarded to a wide area network, so as to enable the Bluetooth terminal to access a network. When a Bluetooth terminal that needs to access a network is an authorized device, a Bluetooth network sharing function can be activated automatically in the present invention, so as to achieve a simple operation and low time consumption for a Bluetooth terminal to access a network.
Referring to FIG. 2, FIG. 2 is a flowchart of another network access method according to an embodiment of the present invention, where a Bluetooth terminal is a PDA, and an electronic device that provides the PDA with a Bluetooth network sharing function is a mobile phone having a Bluetooth AP function. As shown in FIG. 2, the method in this embodiment includes:
201. A mobile phone performs Bluetooth pairing with a PDA, and the mobile phone receives an authorization request sent by the PDA.
Optionally, by using signaling in a process of the Bluetooth pairing, the PDA sends an authorization request, and the authorization request may be a protocol agreed upon between the mobile phone and the PDA.
202. The mobile phone accepts the authorization request and identifies the PDA as an authorized device.
203. The mobile phone establishes a Bluetooth connection to the PDA.
204. The mobile phone receives a network access request sent by the PDA.
The network access request may be an HTTP request.
205. When the PDA is an authorized device, the mobile phone activates the Bluetooth network sharing function.
206. The mobile phone provides the PDA with a network connection.
For a method for providing the PDA with a network connection by the mobile phone, refer to the embodiment of FIG. 1, and details are not described herein again.
207. If the mobile phone does not receive a new network request within a preset time, the mobile phone turns off the Bluetooth network sharing function.
After the mobile phone forwards a previous network access request to a wide area network, if a new network access request is not received within a preset time, the mobile phone turns off the Bluetooth network sharing function.
In this embodiment, by using signaling in a process of Bluetooth pairing, a PDA sends an agreed-upon authorization request protocol to a mobile phone, so that the mobile phone identifies the PDA as an authorized device, and when the PDA initiates a network request subsequently, the mobile phone identifies the PDA automatically and turns on a Bluetooth AP function for the PDA. In this embodiment, the PDA can access a network by using Bluetooth without Wi-Fi, achieving a simple process and low time consumption for network access.
Referring to FIG. 3, FIG. 3 is a flowchart of still another network access method according to an embodiment of the present invention, where a Bluetooth terminal is a PDA, and an electronic device that provides the PDA with a Bluetooth network sharing function is a mobile phone having a Bluetooth AP function. As shown in FIG. 3, the method in this embodiment includes:
301. A mobile phone performs Bluetooth pairing with a PDA.
302. The mobile phone establishes a Bluetooth connection to the PDA.
303. The mobile phone prompts a user to input an authorization confirmation instruction by using a human-computer interaction manner.
The human-computer interaction manner may be: the mobile phone displays, on a screen, information that prompts the user whether to confirm authorization for the device, and the user may confirm authorization by using a corresponding confirmation button and may abandon authorization by using a corresponding cancel button.
304. The mobile phone receives the authorization confirmation instruction input by the user.
305. The mobile phone identifies the PDA as an authorized device.
When the user inputs the authorization confirmation instruction by using the corresponding confirmation button, the mobile phone identifies the PDA as an authorized device after receiving the confirmation instruction.
306. The mobile phone receives a network access request sent by the PDA.
The network access request may be an HTTP request.
Step 303 to step 305 may also be executed after step 306. After the mobile phone performs the Bluetooth pairing with the PDA, the mobile phone does not immediately prompt the user to input an authorization confirmation instruction. However, after step 306, the mobile phone is triggered to execute step 303 after receiving the network access request sent by the PDA, and execute step 305 after receiving the authorization confirmation instruction input by the user.
307. When the PDA is an authorized device, the mobile phone activates the Bluetooth network sharing function.
308. The mobile phone provides the PDA with a network connection.
For a method for providing the PDA with a network connection by the mobile phone, refer to the embodiment of FIG. 1, and details are not described herein again.
