Abstract
Allowing multiple copies of authentication information for a mobile telephone to exist in switching nodes of a distributed switching system. The mobile telephone is only registered on one switching node at a time. One copy is maintained on the resident switching node, and another copy is maintained on the switching node on which the mobile telephone was last registered other than the resident switching node. If the mobile telephone normal only registers on the resident switching node and one other switching node, the authentication information is present on both switching nodes, and both always have the authentication information to register the mobile telephone stored internally which speeds up the registration process. Further, the authentication information does not have to be repeatly communicated through the distributed switching system. If the switching nodes are arranged into an authentication hierarchical structure, the authentication information remains stored on a switching node that last used the authentication information within the authentication hierarchical structure, so that all switching nodes in that authentication hierarchical structure can access the authentication information.

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.
