Abstract

A wireless data card includes a detecting module that is adapted to send a notification message to an executing module after detecting a DNS resolution request sent by a computer and detecting that no user account information exists in the wireless data card. An executing module is adapted to receive the notification message sent by the detecting module, to send prompt information to the computer so as to prompt a user to input the user account information, and to write the input user account information into the wireless data card so that the computer can use the user account information to access the Internet through the wireless data card.

Claims

1. A wireless data card connected to a computer, the wireless data card comprising:

a detecting module, adapted to send a notification message after detecting a Domain Name System (DNS) resolution request sent by the computer and detecting that no user account information exists in the wireless data card; and

an executing module, adapted to receive the notification message sent by the detecting module, to send prompt information to the computer so as to prompt a user to input the user account information, and to write the input user account information into the wireless data card so that the computer can use the user account information to access the Internet through the wireless data card.

2. The wireless data card according to claim 1, further comprising:

an address allocating module, adapted to allocate a private Internet Protocol (IP) address to the computer; and

an address translating module, adapted to translate addresses between the private IP address and a public IP address of the computer.

3. The wireless data card according to claim 1, further comprising:

a Graphic User Interface (GUI) module, adapted to provide the computer with a GUI for monitoring and configuring the wireless data card.

4. The wireless data card according to claim 1, further comprising:

a storage unit, adapted to store the user account information input by the user and preset default account information, wherein the default account information is used for logging in to a server of an operator of the wireless data card to obtain the user account information.

5. The wireless data card according to claim 1, further comprising:

a configuring module, adapted to configure a first physical address for communicating with the computer and a second physical address for communicating in a public network.

6. The wireless data card according to claim 5, wherein all wireless data cards have the same first physical address.

7. A method of operating a wireless data card that is connected to a computer, the method comprising:

sending prompt information to the computer after detecting a Domain Name System (DNS) resolution request sent by the computer and detecting that no user account information exists in the wireless data card, wherein the prompt information prompts a user to input the user account information; and

writing the input user account information into the wireless data card so that the computer can use the user account information to access the Internet through the wireless data card.

8. The method according to claim 7, further comprising using default account information to log in to a server of an operator of the wireless data card to obtain the user account information.

9. The method according to claim 8, wherein the default account information is preset in the wireless data card.

10. The method according to claim 7, further comprising providing the computer with a Graphic User Interface (GUI) for monitoring and configuring the wireless data card.

11. The method according to claim 7, wherein a first physical address for communicating with the computer and a second physical address for communicating in a public network are configured in the wireless data card.

12. The method according to claim 11, wherein all wireless data cards have the same first physical address.

13. A method of operating a wireless data card that is connected to a computer, the method comprising:

detecting a Domain Name System (DNS) resolution request sent by the computer and detecting that no user account information exists in the wireless data card;

sending a notification message after detecting the DNS resolution request and detecting that no user account information exists in the wireless data card;

in response to the notification message, sending prompt information to prompt a user to input the user account information; and

writing the input user account information into the wireless data card so that the computer can use the user account information to access the Internet through the wireless data card.

14. The method according to claim 13, further comprising:

allocating a private Internet Protocol (IP) address to the computer; and

translating addresses between the private IP address and a public IP address of the computer.

15. The method according to claim 13, further comprising providing the computer with a GUI for monitoring and configuring the wireless data card.

16. The method according to claim 13, further comprising storing the user account information input by the user and preset default account information, wherein the default account information is used for logging in to a server of an operator of the wireless data card to obtain the user account information.

17. The method according to claim 13, further comprising configuring a first physical address for communicating with the computer and a second physical address for communicating in a public network.

18. The method according to claim 17, wherein all wireless data cards have the same first physical address.
