Abstract

A method and/or apparatus to permit non-authorized wireless mobile devices access to public domain services of a local area network. One embodiment of the invention provides a wireless access point device, with a wireless port and a wired network port, with at least two modes of operation to permit authorized mobile devices access to network services and non-authorized mobile devices access to a particular set of network services. A list of free and/or pay-per-use network services is provided to non-authorized mobile devices to select the desired service(s). For pay-per-use services, a mobile device user can provide a form of payment for validation.

8. The method of claim 5 further comprising:

providing a secure transmission of information between the non-authorized mobile device and the access point device.

9. The method of claim 5 further comprising:

sending payment information from the non-authorized mobile device to the access point device wirelessly.

10. The method of claim 5 further comprising:

validating the payment information provided by the non-authorized mobile device; and

providing the validation results to the non-authorized mobile device.

11. The method of claim 10 further comprising:

establishing a connection between the non-authorized mobile device and a selected network service only if payment validation is successful.

12. The method of claim 11 further comprising:

if a payment for the non-authorized mobile device expires, disconnecting the non-authorized mobile device from a selected network service of the available network services.

13. The method of claim 1 further comprising:

performing data exchanges between the non-authorized mobile device and a selected network service of the available network services through the access point.

14. The method of claim 1 further comprising:

disconnecting the non-authorized mobile device from the access point device to terminate access to the available network services.

15. The method of claim 1 wherein the establishment of the connection uses an authentication procedure provided in the Electrical and Electronics Engineers (IEEE) Standard 802.11 Specification or its supplements.

28. The method of claim 1, wherein the private mode of operation includes a secure service as specified in the Electrical and Electronics Engineers (IEEE) Standard 802.11 Specification or its supplements.

29. The method of claim 1, wherein the plurality of modes of operation includes a simultaneous mode of operation, the simultaneous mode of operation providing authorized mobile devices access to private network services and authorized or non-authorized mobile devices access to public network services simultaneously via the access point device.

32. The method of claim 15, wherein:

the establishment of a connection in the private mode comprises use of Secure Service procedures as specified in IEEE Standard 802.11 Specification or its supplements; and

the establishment of a connection in the public mode comprises use of Open System procedures as specified in IEEE Standard 802.11 Specification or its supplements.

16. A machine-readable medium having one or more instructions for enabling a non-authorized user to wirelessly access a number of network services, which when executed by a processor, causes the processor to perform operations comprising:

wirelessly transmitting a synchronization signal indicating one of a plurality of modes of operation for an access point, the plurality of modes of operation including a private mode of operation for authorized devices and a public mode of operation for authorized or non-authorized devices;

wirelessly transmitting available network services if the mode of operation is the public mode of operation;

receiving a request for connection establishment from a non-authorized user in response to the transmission of a synchronization signal for the public mode of operation;

establishing a connection with the non-authorized user;

receiving a request for access to a selected network service, from among the available network services, by the non-authorized user; and

providing the non-authorized user access to the selected network service;

wherein establishing a connection in the private mode comprises use of authentication and association handshakes, and wherein establishing a connection in the public mode comprises use of a registration process.

17. The machine-readable medium of claim 16 further comprising:

requesting a form of payment from the non-authorized user for access to pay-per-use network services.

18. The machine-readable medium of claim 17 further comprising:

validating the payment information provided by the non-authorized user.

19. The machine-readable medium of claim 18 further comprising:

if payment from the non-authorized mobile device expires, disconnecting the non-authorized mobile device from the selected network service.

20. The machine-readable medium of claim 16 further comprising:
