Abstract
The present invention provides a registration method for managing NAT shutdown. In Internet communication field, a user must perform registrations intermittently to a server through NAT, and increase the time interval of registration step by step. But NAT itself will shutdown if no packet is passed through for a long period. The registration method of the present invention is to adjust the time interval of registration step by step so that the time interval of registration is slightly less than the shutdown time of NAT, and then fix the time interval of registration to assure that all of the Invite packet can pass through without blocking up by the shutdown of NAT.
