A mobility management optimizing function in a wireless network receives geographic location information associated with a user equipment device (UE), wherein the UE is associated with a vehicle and generates a predictive handover schedule based on the received location information. Handover processing is initiated based on the predictive handover schedule, wherein initiating the handover processing comprises: transmitting one or more handover initiation messages to a plurality of cell sites in a service provider wireless network at times based on the predictive handover schedule, wherein, upon receipt of a handover initiation message, the plurality of cell sites will initiate handover processing based on the received handover initiation message.
