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.
A computer program product encoding a computer program for executing a computer process on a mobile node, a network being coupled to a first base station and a second base station and the mobile node being fully authenticated by the first base station for fully authenticated access to the network, the computer process providing the mobile node with credential authenticated access to the network through the second base station prior to completion of full authentication of the mobile node by the second base station, the computer process comprising:
In a network coupled to a first base station and a second base station and the mobile node being fully authenticated by the first base station for fully authenticated access to the network, a method for providing the mobile node with credential authenticated access to the network through the second base station prior to completion of full authentication of the mobile node by the second base station, the method comprising:
A mobile node capable of coupling to a network, the network being coupled to a first base station and a second base station and the mobile node being fully authenticated by the first base station for fully authenticated access to the network, the mobile node being capable of accessing with credential authenticated access to the network through the second base station prior to completion of fall authentication of the mobile node by the second base station, the mobile node comprising:
A computer program product encoding a computer program for executing a computer process on a mobile node, the computer process providing the mobile node with credential authenticated access to a network through a first base station after termination of fully authenticated access to the network through the first base station, the computer process comprising:
A method of providing a mobile node with credential authenticated access to a network through a first base station after termination of fully authenticated access to the network through the first base station, the method comprising:
A mobile node capable of establishing credential authenticated access to a network through a first base station after termination of fully authenticated access of the mobile node through the first base station, the mobile node comprising:
A computer program product encoding a computer program for executing a computer process on a computer system, a network being coupled to a first and a second base station, the computer process providing a mobile node with credential authenticated access to the network through the second base station prior to completion of full authentication of the mobile node through the second base station, the computer process comprising:
In a network coupled to a first and a second base station, a method of providing a mobile node with credential authenticated access to the network through the second base station prior to completion of full authentication of the mobile node through the second base station, the method comprising:
A first base station providing a mobile node with credential authenticated access to the network through the second base station prior to completion of full authentication of the mobile node through the second base station, the first base station comprising:
A computer program product encoding a computer program for executing a computer process on a computer system, wherein the network is coupled to a first and a second base station and the mobile node is fully authenticated by the first base station, the computer process for providing a mobile node with credential authenticated access to a network through a second base station prior to full authentication of the mobile node by the second base station, the mobile node having a credential received from the first base station responsive to full authentication by the first base station, the computer process comprising:
In a network coupled to a first base station and a second base station, a method of providing a mobile node with credential authenticated access to the network through the second base station prior to full authentication of the mobile node by the second base station, the mobile node having previously been fully authenticated by the first base station, the mobile node having a credential received from the first base station responsive to full authentication by the first base station, the method comprising:
An authenticating base station for providing a mobile node with credential authenticated access to a network through the authenticating base station prior to full authentication of the mobile node through the authenticating base station, the mobile node having a credential received from another base station responsive to being fully authenticated by the other base station, the authenticating base station comprising:
