Abstract
Abstract Methods and apparatus for assigning an IP address to a mobile node during registration are disclosed. According to one aspect, a registration request is sent by a mobile node. A mobile node ID associated with the mobile node is obtained. A registration request packet is then composed. The registration request packet stores at least a portion of the mobile node ID in the registration request packet. The registration request packet is sent to a Home Agent associated with the mobile node. According to another aspect, a registration request packet is processed by a Home Agent. The Home Agent receives the registration request packet and ascertains whether the mobile node designated by the registration request packet needs an IP address. An IP address is assigned to the mobile node if it is ascertained that the mobile node needs an IP address. A registration reply specifying the IP address assigned to the mobile node is then composed. According to another aspect, a registration reply packet received by a Foreign Agent is processed. The registration reply packet is received from a Home Agent. The registration reply packet specifies a portion of a mobile node ID and an IP address associated with a mobile node. The portion of the mobile node ID and the IP address are obtained from the registration reply packet. A visitor table is updated with a mapping of the mobile node ID to the IP address. The registration reply packet is sent to the mobile node.
