  • Solving PANA bootstrapping timing problem
    Patent number: 8270948
    Abstract: A method for avoiding loss of data or consumption of resources between a mobile node and an new access network in which an authentication agent performs authentication with an authentication client of the mobile node to effect access to an enforcement point of said access network, said method comprising informing an authentication client of said mobile node that an authentication agent has completed an installation process with the enforcement point.

  • Assisted proactive IP address acquisition
    Patent number: 8223716
    Abstract: The present invention relates to reducing the time required to provide an IP address to a mobile node by pro-actively obtaining IP addresses, through the use of PANA-assisted pro-active IP address acquisition, IKEv2-assisted proactive IP address acquisition, or by pro-active IP address acquisition using DHCP only.

  • ASSISTED PROACTIVE IP ADDRESS ACQUISITION
    Publication number: 20080130647
    Abstract: The present invention relates to reducing the time required to provide an IP address to a mobile node by pro-actively obtaining IP addresses, through the use of PANA-assisted pro-active IP address acquisition, IKEv2-assisted proactive IP address acquisition, or by pro-active IP address acquisition using DHCP only. Where a DHCP is used to pre-configure an IP address in an MPA framework, a PAA generates a plurality of Session-Ids, the plurality of Session-Ids is maintained as a pool of Session-Ids, a Session-Id is retrieved from the pool when the PAA sends a PANA-Auth-Request, and providing a pre-generated IP address to an MN reduces pre-authentication time. Where a IKEv2-assisted pro-active IP address acquisition to pre-fetch IP addresses, is used to reduce the time required to provide an IP address to a MN an IP address is obtained from a CTN as part of a standard IKEv2 procedure.
