Abstract

A device to request and receive a packet of information that details WLAN network information prior to association with the WLAN. This network information about the WLAN allows the device to complete automated network selection and enrollment.

Claims

1. A device to operate in a Wireless Local Area Network (WLAN), comprising:

a transceiver to transmit data packets that query configuration information about the WLAN; and

a connection manager to analyze details about the WLAN received in response to the query that determine pre-association WLAN decisions to automate network selection in the device.

2. The device of claim 1 wherein the configuration information received by the device in response to the query includes authentication requirements for the device to join the WLAN.

3. The device of claim 1 wherein the configuration information received by the device in response to the query includes information of open access or an access charge for the device to join the WLAN.

4. The device of claim 1 wherein the configuration information received by the device in response to the query includes network type and support for online enrollment for the device to join the WLAN.

5. The device of claim 1 wherein the configuration information received by the device in response to the query includes preferred enrollment methods for Unlicensed Mobile Alliance (UMA) access and Extensible Authentication Protocol (EAP).

6. The device of claim 1 wherein the connection manager executes network selection based on user preferences.

7. A Wireless Local Area Network (WLAN) device, comprising:

a transceiver to receive and transmit data packets; and

a processor coupled to the transceiver to issue a query request that elicits a received response of stored configuration information having details about a WLAN that the processor uses to make pre-association WLAN decisions about selecting and joining the WLAN.

8. The WLAN device of claim 7 wherein a Connection Manager (CM) module in the WLAN device detects a type of WLAN network.

9. The WLAN device of claim 8 wherein the CM module in the WLAN device uses the configuration information to establish network selection and enrollment.

10. The WLAN device of claim 8 wherein the CM module in the WLAN device makes the configuration information available to other users.

11. The WLAN device of claim 8 wherein the CM module in the WLAN device makes network type configuration information available for display by the device to allow a user to make connection decisions or the network type configuration information is programmatically handled within the WLAN device.

12. The WLAN device of claim 8 further comprising:

a network type and online enrollment Information Element (IE) that includes information that pertains to the network type and supported online enrollment methods for a network.

13. A WLAN connecting first and second devices, comprising:

dual antenna;

a transceiver in the first device coupled to the dual antenna to query for WLAN network characteristics information; and

a storage memory in the second device accessible to provide configuration information about WLAN network type and enrollment information in response to the query that allows the first device to make pre-association WLAN decisions to automate network selection in the first device.

14. The WLAN of claim 13 wherein the first device listens to the WLAN network characteristics information prior to WLAN association to make informed decisions as to whether to connect to the network.

15. The WLAN of claim 13 wherein the storage memory maintains network type bits that provide the WLAN network type including public WLAN and private WLAN.

16. The WLAN of claim 13 wherein the storage memory maintains online enrollment capability bits that provide status of authentication requirements.

17. The WLAN of claim 13 wherein the storage memory maintains online enrollment capability bits that provide status of enrollment support.

18. The WLAN of claim 13 wherein the storage memory maintains online enrollment capability bits that provide status of open access or fee-based access.

19. The WLAN of claim 13 wherein the storage memory maintains an online enrollment information bitmap that contains a list of supported online enrollment methods UAM and EAP.
