Abstract
A method is disclosed for a mobile node to register with a home agent on a home network when the mobile node is located near a border between two or more foreign domains. A buffer zone is defined that includes the border between the foreign domains and overlapping portions of the foreign domains. When the mobile node is located inside the buffer zone, mobile node re-registration with either foreign agent is limited to once for each registration lifetime rather than each time the mobile node crosses from one foreign domain to another foreign domain.
