Abstract:
1. A method reducing the time required to provide an Internet Protocol (IP) address to a mobile node (MN) using a Dynamic Host Configuration Protocol (DHCP) to pre-configure an IP address in a Media-independent Pre-Authentication (MPA) framework, comprising the steps of: a) a Protocol for carrying Authentication for Network Access (PANA) authentication agent (PAA) generating a plurality of Session-Ids, b) maintaining said plurality of Session-Ids as a pool of Session-Ids, c) retrieving a Session-Id from said pool when said PAA sends the first PANA message that requires a Session-Id, wherein providing a pre-generated IP address to an MN reduces pre-authentication time, and wherein said PAA acts as either a DHCP relay or DHCP client when sending a DHCP request to a DHCP server using a DHCP Client Identifier Option that contains a pre-generated PANA Session-Id, and said PAA receives from the DHCP server an IP address based on said identifier.
