Abstract
Methods and apparatus are presented to reduce the number of registration requests transmitted by a mobile node to a foreign agent. Rather than always sending the re-registration request at pre-determined times before the expiry of registration lifetime, re-registration requests are transmitted only if some data transfer takes place after a time period demarcated by the previous successful registration.
