Many examples exist of a mobile node moving between the operational zones of
multiple network access points or base stations. To minimize delay in re-authenticating
with the network through a new base station, an additional form authenticated access
mode called "credential authenticated" access is provided. The mobile unit is fully
authenticated in the first base station (e.g., the user has logged in and paid
for service). Thereafter, the first base unit transmits a "credential" to the mobile
node that may be used by other base stations to establish trust with the mobile
node prior to full re-authentication. Upon entering the operational zone of the
second base station, the mobile node can transmit the credential to the second
base station, which may accept the credential and allow access by the mobile node
to the network through the second base station before full authentication has completed.
