Embodiments of the present disclosure disclose a handover processing method. The method includes: before a source Donor E-UTRAN Node B (DeNB) makes a handover decision, sending auxiliary information for obtaining a pre-configured parameter; receiving the pre-configured parameter; and performing a handover from the source DeNB to a target DeNB according to the pre-configured parameter. The relay device includes: a first sending module, configured to send, before a source DeNB makes a handover decision, auxiliary information for obtaining the pre-configured parameter; a first receiving module, configured to receive the pre-configured parameter; and a handover module, configured to perform a handover from the source DeNB to a target DeNB according to the pre-configured parameter. According to the embodiments of the present disclosure, the technical problem that the service interruption of the UE controlled by the relay device is prolonged due to a long delay in the handover operation is solved.
