Abstract
A method for providing private sidestream transmissions between a first and second client in a wireless network generally includes sending a location discovery request from a first client to an access point and receiving a location discovery response from the access point. The response includes a ticket encrypted with a session key of the second client and containing a sidestream key. The method further includes sending a direct communication request from the first client to the second client. The request includes the ticket and an authenticator encrypted with the sidestream key. A direct communication response including an updated authenticator is received from the second client. A method and apparatus for secure context transfer during client roaming are also disclosed.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
