Personal mobility: In universal personal telecommunications, (a) the ability of a user to access telecommunication services at any UPT terminal on the basis of a personal identifier, and (b) the capability of the network to provide those services in accord with the user's service profile.

Note 1: Personal mobility involves the network's capability to locate the terminal associated with the user for the purposes of addressing, routing, and charging the user for calls.

Note 2: "Access" is intended to convey the concepts of both originating and terminating services.

Note 3: Management of the service profile by the user is not part of personal mobility. The personal mobility aspects of personal communications are based on the UPT number.
