1. A cellular network supporting a preemptive preparation of a handover for a user entity,
wherein the cellular network comprises a microprocessor configured for, or an electronic circuit configured for, or a computer programmed with a program stored in a memory configured for
request, from the user entity, a transmission of predicted future route information;
receiving, from the user entity, the predicted future route information, the predicted future route information including list of locations along the predicted future route, determining, based on the predicted future route information, a preliminary set of one or more base stations of the cellular network, wherein the cardinality of the set of one or more base stations is greater than one;
sending a query from a centralized unit of the cellular network to each of the preliminary set of one or more base stations of the cellular network regarding an accessibility of the cellular network via the respective base station at an expected time at which the user entity enters a cell of the respective base station, and
sending an answer from the respective base station to the centralized unit.
