  • Method for synchronizing registration information within intra-domain
    Patent number: 7085813
    Abstract: Disclosed herein is a method for synchronizing user registration information in an inter-domain. In this synchronization method, the current position information of a random user is registered through a register message when the user moves from one user agent to another. An up-sync message is transmitted upstream of a tree structure and a down-sync message is transmitted downstream of the tree structure when user registration information is created or changed. The synchronization of the user registration information is carried out in upper and lower session initiation protocol servers/registrars having received the up-sync and down-sync messages, respectively.
