Abstract

A method for facilitating communication between a wireless client and a network is disclosed. The method comprises communicating information between the wireless client and the network prior to associating the wireless client to the network. The information can be related to setup features or services.

Claims

1. A method of selecting a wireless access point by a wireless client, the method comprising:

receiving one or more messages from one or more wireless access points prior to associating with the wireless access points, each of messages including first information regarding network services provided by a respective wireless access point from the one or more wireless access points;

selecting a first wireless access point from the wireless access points based on the first information; and

associating with the first wireless access point;

wherein the first information includes;

a connection speed between the respective wireless access point and a wide area network (WAN) beyond a local area network (LAN) to which the wireless access point belongs; and

a quality of service supported by the WAN.

2. The method of claim 1 wherein the first information further comprises whether the LAN is connected to the WAN.

3. The method of claim 1, further comprising:

transmitting a request to the wireless access points prior to associating with the wireless access points, the request including second information regarding network services desired by the wireless client;

wherein the second information includes;

a desired connection speed between respective LANs to which the wireless access points belong and corresponding WANs beyond the respective LANs; and

a desired quality of service supported by the corresponding WANs.

4. The method of claim 3 wherein the second information further comprises a desire for a connection between the respective LANs and the corresponding WANs.

5. The method of claim 3 wherein one of the messages includes at least one 802.11 information element.

6. The method of claim 3 wherein the request includes at least one 802.11 information element.

7. The method of claim 3 wherein at least one of the desired network services is included in the provided network services.

8. The method of claim 1 wherein the WAN is an Internet.

9. The method of claim 1 wherein the messages include at least one 802.11 information element.

10. The method of claim 1 wherein the first information further includes information associated with one or more items selected from a group consisting of:

client service type,

network address translation scenario,

network address port translation scenario,

virtual private network utilization,

access point upstream network utilization,

access point management,

access point owner,

access point operator,

access point manufacturer,

access point model,

access point type,

access point firmware version, and

cost information associated with use of the respective wireless access point.

11. The method of claim 1 wherein the wireless client is selected from a group consisting of a portable wireless client, a personal digital assistant, a telephone, a printer, a data storage device, a camera, a music storage device, an audio player, a video player, and a portable computer.

12. The method of claim 1 wherein the one or more messages are beacons.

13. A method of selecting a wireless access point by a wireless client, the method comprising:

receiving one or more messages from one or more wireless access points prior to associating with the wireless access points, each of messages including first information regarding network services provided by a respective wireless access point from the one or more wireless access points;

selecting a first wireless access point from the wireless access points based on the first information; and

associating with the first wireless access point;

wherein the first information includes whether or not a local area network (LAN) to which the access point belongs is connected to a wide area network (WAN).

14. A networking device comprising:

a memory circuit to store first information regarding network services provided by the networking device;

a receiver; and

a transmitter;

wherein;

the receiver is configured to receive a request from a wireless client prior to the wireless client associating with the networking device, the request comprising second information regarding network services desired by the wireless client;

the transmitter is configured to transmit a response to the request received from the wireless client, the response including at least a portion of the first information;

the first information includes whether a local area network (LAN) to which the networking device belongs is connected to a wide area network (WAN) beyond the LAN; and

the second information includes a desire that the LAN be connected to the WAN.

15. The networking device of claim 14 wherein the networking device is configured to associate with the wireless client.

16. The networking device of claim 14 wherein the networking device is an access point.

17. The networking device of claim 14 wherein the transmitter is further configured to transmit a beacon, the beacon including at least a portion of the first information.

18. The networking device of claim 14 wherein the first information further includes information associated with one or more items selected from a group consisting of:

a connection speed between the networking device and the WAN,

a quality of service supported by the WAN,

client service type,

network address translation scenario,

network address port translation scenario,

virtual private network utilization,

access point upstream network utilization,

access point management,

access point owner,

access point operator,

access point manufacturer,

access point model,

access point type,

access point firmware version, and

cost information associated with use of the networking device.

19. The networking device of claim 14 wherein the WAN in an Internet.

20. The networking device of claim 14 wherein the response includes at least one 802.11 information element.
