Abstract
Advance handover notice is given to a 'target' base station of a group of mobile radio connections that will be soon be handed over the to the target base station from a current, 'serving' base station. This advance notice permits the target base station to reserve resources and prepare for the handovers of the mobile radio connections. In addition, the handover operation is initiated earlier than it would be otherwise. Early handover initiation is possible because the route of the moving vehicle is known or is predictable, and therefore, the serving and target base stations are known or may be predicted in advance. In this way, the likelihood of successful handovers with no dropped calls is increased for mobile stations moving at high speed and/or together as a group.
