    Abstract: A method and apparatus for updating information in a personal mobility database server with information concerning a user's nomadicity.

PMDNS takes user's terminal personalization, together with usage profile, session characteristics into account to map a party's identifier to a terminal's identifier. The IP address of the user's current location is used in concert with the terminal's identifier, which is itself an IP address, to route incoming computing communications connection requests to the current location of the user. This information will be returned by the PMDNS directory server to the access network for the setup of the communications.
