1. A user entity for communication over a cellular network, wherein the user entity is configured to
manage a set of one or more preemptively prepared handovers,
continuously check a schedule of a time-varying tracking area whether the user entity leaves the time-varying tracking area, and
send a tracking area update message to the cellular network in case of the user entity leaving the time-varying tracking/paging area.
