Abstract
Methods and apparatuses for conserving addresses. The invention allows a mobile node to manage its own address, shifting responsibility away from the home agent. The home agent is able to detect when a mobile node has already been assigned an address for use of resources on the network. When the home agent recognizes that the mobile address has already been assigned an address, it allows the mobile node to use its already-assigned address in connection with mobile IP services. Additionally, the mobile node can be notified that it is now responsible for renewing the address.
