ABSTRACT:
Methods and apparatus for processing a registration request packet received from a mobile node during registration are disclosed. The registration request packet is received from a mobile node. The Home Agent then determines whether an IP address has previously been assigned to the mobile node. When the Home Agent determines that an IP address has previously been assigned to the mobile node, the Home Agent obtains the IP address previously assigned to the mobile node, composes a registration reply including the IP address previously assigned to the mobile node and sends the registration reply to the mobile node. When the Home Agent determines that an IP address has not previously been assigned to the mobile node, the Home Agent assigns an IP address to the mobile node, composes a registration reply including the IP address and sends the registration reply to the mobile node.
