The present disclosure reduces the time required to perform wireless service handover by detecting the movement status of the mobile relay relative to a candidate DeNB as to determine whether a mobile relay is approaching or leaving a candidate handover DeNB.

The movement status could be determined based on the propagation time of signals, a list of neighbor cell information, or the Doppler effect.
