Abstract

A wireless network system provides for a wireless access point. The wireless access point is configured to receive data, from a wireless computing device, that is encrypted using encryption key data and to determine if the encryption key data corresponds to a home computing device or a visitor computing device. An IP address is assigned to the wireless computing device to identify it on the network system. The IP address is assigned based upon the encryption key data.

Claims

1. A method of granting network access to a wireless computing device, said method comprising the steps of:

receiving data encrypted using predetermined encryption key data from a wireless computing device via a wireless connection;

said encryption key data corresponds to a predetermined user class; and

assigning an Internet protocol (IP) address to said wireless computing device that is indicative of said predetermined user class, based upon said encryption key data.

2. The method of claim 1, further comprising the step of granting said wireless computing device access to a visitor resource, where said IP address corresponds to a visitor computing device, said visitor resource comprises a network resource that is accessible to the visitor computing device.

3. The method of claim 1, further comprising the step of granting said wireless computing device access to a home resource, where said IP address corresponds to a home computing device, said home resource comprises a network resource that is accessible by the home computing device.

4. The method of claim 2, wherein said visitor resource comprises the Internet.

5. The method of claim 3, wherein said home resource comprises an Intranet.

6. The method of claim 5, wherein said home resource further comprises the Internet.

7. The method of claim 1, wherein said user class corresponds to a visitor computing device.

8. The method of claim 1, wherein said IP address determines the extent to which said wireless computing device is allowed access to resources on said network.

9. A wireless access point configured to receive data, encrypted using predetermined encryption key data that corresponds to a predetermined user class, from a wireless device and to assign an Internet Protocol (IP) address based on the predetermined encryption key data to said wireless device to identify the wireless device on a network, the IP address indicative of the predetermined user class.

10. The wireless access point according to claim 9, further comprising:

a controller configured to receive the data and to assign the IP address.

11. The wireless access point of claim 10, further comprising memory for storing software instructions for controlling the operation of said controller.

12. The wireless access point of claim 10, further comprising a wireless transceiver for exchanging data with the wireless device.

13. A wireless access point comprising:

a controller;

a memory;

a wireless transceiver for exchanging data with a wireless computing device;

a connector for connecting to a network; and

wherein said controller is configured to receive data, encrypted using predetermined encryption key data that corresponds to a predetermined user class, from said wireless computing device and to assign an Internet Protocol (IP) address to said wireless computing device based on the predetermined encryption key data to identify said wireless computing device on said network, the IP address indicative of the predetermined user class.

14. The wireless access point of claim 13, wherein said wireless computing device comprises a visitor computing device.

15. The wireless access point of claim 14, wherein said controller is further configured to assign a visitor IP address to said visitor computing device where said encryption key data comprises a visitor encryption key.

16. The wireless access point of claim 13, wherein said wireless computing device comprises a borne computing device.

17. The wireless access point of claim 16, wherein said controller is further configured to assign a home IP address to said borne computing device where said encryption key data comprises a home encryption key.

18. The wireless access point of claim 13, wherein said controller is further configured to provide a firewall to said network.

19. A method of granting network access to a wireless computing device, said method comprising the steps of:

receiving data encrypted using predetermined encryption key data from a wireless computing device via a wireless connection;

determining whether the encryption key data is a visitor encryption key or a home encryption key; and

assigning an Internet protocol (IP) address to said wireless computing device based upon said encryption key data,

wherein assigning the IP address comprises assigning a visitor IP address to the wireless computing device in response to determining that the encryption key data is a visitor encryption key, and

wherein assigning the IP address comprises assigning a home IP address to the wireless computing device in response to determining that the encryption key data is a home encryption key.

20. The method of claim 19, wherein the visitor IP address contains at least a first predetermined digit to identify the wireless computing device as a visitor wireless computing device, and the home IF address contains at least a second predetermined digit, different from the first predetermined digit, to identify the wireless computing device as a home wireless computing device.

21. A wireless access point configured to receive data, encrypted using predetermined encryption key data, from a wireless device and to assign an Internet Protocol (IP) address based on the predetermined encryption key data to said wireless device to identify the wireless device on a network, the wireless access point further configured to:

determine whether the encryption key data is a visitor encryption key or a home encryption key,

wherein the assigned IP address is a visitor IP address in response to the encryption key data being a visitor encryption key, and

wherein the assigned IP address is a home IP address in response to the encryption key data being a home encryption key.

22. A wireless access point comprising:

a controller;

a memory;

a wireless transceiver for exchanging data with a wireless computing device;

a connector for connecting to a network; and

wherein said controller is configured to receive data, encrypted using predetermined encryption key data, from said wireless computing device and to assign an Internet Protocol (IP) address to said wireless computing device based on the predetermined encryption key data to identify said wireless computing device on said network, wherein the controller is configured to further;

determine whether the encryption key data is a visitor encryption key or a home encryption key,

wherein the assigned IP address is a visitor IP address in response to the encryption key data being a visitor encryption key, and

wherein the assigned IP address is a home IP address in response to the encryption key data being a home encryption key.

23. A computer-readable medium containing instructions that when executed cause a system to:

receive, from a wireless computing device, data encrypted using encryption key data;

determine whether the encryption key data is a visitor encryption key or a home encryption key;

in response to determining that the encryption key data is a visitor encryption key, assign a visitor Internet Protocol (IP) address to the wireless computing device; and

in response to determining that the encryption key data is a home encryption key, assign a home IP address to the wireless computing device, the home IP address being different from the visitor IP address.

24. The computer-readable medium of claim 23, wherein each of the visitor IP address and home IP address contains plural digits, at least one digit in the visitor IP address being different from a corresponding at least one digit in the home IP address.
