Abstract: A handover method in a mobile CCN. In the method, when detecting a UE performing a handover, a source local CCNx node caches data directed to the UE. The source local CCNx node transmits a request to stop transmission of the data directed to the UE to a target local CCNx node based on a condition. The target local CCNx node requests the source local CCNx node to stop transmission of contents that are being cached. The source local CCNx node transmits cached contents to the target local CCNx node. The target local CCNx node requests a CCNx entry node to stop transmission of specific contents based on a condition. The CCNx entry node transmits contents to the target local CCNx node. When detecting, the UE completing the handover, the target local CCNx node transmits the contents received from the CCNx entry node to the UE.
