Abstract

Described is a system and method for providing differentiated service levels to wireless devices in a wireless network. The method comprises receiving, on a first network arrangement connected to a network, an authentication request from a wireless device. The network uses a first access protocol having a plurality of access categories and the wireless device uses a second access protocol. The authentication request including one of the plurality of access categories. The wireless device is verified to ensure that it is authorized to communicate at the one of the plurality of access categories. When the wireless device is verified as authorized, a response is communicated to a second network arrangement that indicates the one of the plurality of access categories is used for communications with the wireless device.

Claims

1. A method, comprising:

receiving, on a first network arrangement connected to a network, an authentication request from a wireless device, wherein the network uses a first access protocol having a plurality of access categories and the wireless device uses a second access protocol, the authentication request including one of the plurality of access categories;

verifying the wireless device is authorized to communicate at the one of the plurality of access categories; and

communicating, when the wireless device is verified as authorized, a response to a second network arrangement that indicates the one of the plurality of access categories is used for communications with the wireless device.

2. The method of claim 1;

wherein the second network arrangement is one of a wireless switch, an access point and an access port.

3. The method of claim 1, wherein the first network arrangement is an authentication server.

4. The method of claim 1, wherein the second access protocol is a legacy protocol not including the plurality of access categories.

5. The method of claim 1, wherein the one of the plurality of access categories in the authentication request is based on an application being executed by the device.

6. The method of claim 1, wherein the first access protocol is an IEEE 802.11e protocol.

7. The method of claim 1, wherein the plurality of access categories includes one of a voice category, a video category, a best effort category and a background category.

8. The method of claim 1, wherein the wireless device is one of a mobile computing device, a PDA, a mobile phone, a laptop computer, a scanner, an RFID reader, a network interface card, a cash register and a bar code reader.

9. The method of claim 1, wherein the authentication request further includes one of (i) a password, (ii) a username, (iii) a certificate and (iv) a token card.

10. The method of claim 9, wherein the one of the plurality of access categories in the authentication request is based on the username in the authentication request.

11. The method of claim 1, wherein the response further includes at least one quality-of-service attribute to be assigned to the device.

12. A system, comprising:

a first network arrangement connected to a network to receive an authentication request from a wireless device, wherein the network uses a first access protocol having a plurality of access categories and the devices uses a second access protocol, the authentication request including one of the plurality of access categories; and

a second network arrangement connected to the network to receive the authentication request from the first network arrangement, verify the wireless device is authorized to communicate at the one of the plurality of access categories and communicate, when the wireless device is verified as authorized, a response to the first network arrangement that indicates the one of the plurality of access categories is used for communications with the wireless device.

13. The system of claim 12, wherein the first network arrangement is one of a wireless switch, an access point and an access port.

14. The system of claim 12, wherein the second network arrangement is an authentication server.

15. The system of claim 12, wherein the one of the plurality of access categories in the authentication request is based on one of an application being executed by the device and a username included in the authentication request.

16. The system of claim 12, wherein the first access protocol is an IEEE 802.11e protocol.

17. The system of claim 12, wherein the plurality of access categories includes one of a voice category, a video category, a best effort category and a background category.

18. The system of claim 12, wherein the response further includes at least one quality-of-service attribute to be assigned to the device.

19. A system comprising a memory storing a set of instructions and a processor to execute the instructions, the set of instructions configured to:

receive an authentication request from a wireless device attempting to connect to a network, wherein the network uses a first access protocol having a plurality of access categories and the wireless device uses a second access protocol, the authentication request including one of the plurality of access categories;

verify the wireless device is authorized to communicate at the one of the plurality of access categories; and

communicate, when the wireless device is verified as authorized, a response indicating the one of the plurality of access categories is used for communications with the wireless device.

20. A system, comprising:

a first means connected to a network for receiving an authentication request from a wireless device, wherein the network uses a first access protocol having a plurality of access categories and the devices uses a second access protocol, the authentication request including one of the plurality of access categories; and

a second means connected to the network for receiving the authentication request from the first means, verifying the wireless device is authorized to communicate at the one of the plurality of access categories and communicating, when the wireless device is verified as authorized, a response to the first means that indicates the one of the plurality of access categories is used for communications with the wireless device.
