摘要：
A method for managing mobility of an AT in a mobile communication system using Mobile IPv4. The AAA and the AT generate a first key for mutual authentication between the AT and a HA, and the AAA and the AG generate a second key for mutual authentication between the AG and the HA. The AG generates a third key for mutual authentication between the AG and the AT. The AT acquires a CoA that it will use in a foreign network. The AT sends an RRQ message to the AG. The AG verifies the RRQ message received from the AT, using a third authentication key. The AG then sends to the HA an RRQ message. The HA verifies the AT and the AG, and allocates an HoA of the AT. The HA sends an RRP message including the allocated HoA of the AT in response to the RRQ message.
